nymphomania

by ed miller


part 1

i was walking along on the first day of college, on my way to my dorm, when i was grabbed from behind. i felt a sharp pain and that's the last thing i remember. i awoke naked in a featureless room, my hands and feet restrained. a bright light was in my eyes, and a woman's voice was in my ears. "you are an experiment," she said. "we are testing certain compounds we believe will genetically alter a living subject, and others that we hope will have an effect on your physical structure and behavior." another pain and i lost consciousness again. when i awoke i felt different. the lights were out, so i couldn't see, but my body felt strange. among other things, there was a peculiar weight on my chest. the restraints felt looser, and i just felt generally smaller. i struggled against my bonds for a while, then i just waited. before long, the lights came on and i could see what was weighing down on my chest. i had breasts! not large ones, but breasts nonetheless. looking down between my legs, i saw what i dreaded: that the change extended down there as well. my dick was gone, and in its place was a pussy! the voice spoke again, from nowhere. "you see the changes we have effected. allow me to explain. we have altered your dna; you are now a fully functional woman. apart from that, we have caused some other changes. every time you orgasm, it increases your sex drive, particularly your craving for cum." "what craving for cum?" i thought, but immediately answered myself. as the thought of a big hard dick entered my mind, my nipples immediately became rock hard and my pussy juices started to flow. "also," the voice continued, "you'll notice some interesting physical effects when you come into contact with sperm. have a nice day." i felt the pain again, and again became unconscious. i woke up in what i assumed was my dorm. i had never seen it, as i was on my way there for the first time when i was kidnapped. "wow, what a weird dream," i thought to myself. as i sat up, i felt my breasts shift and realized it was not a dream. i looked around and concluded that whoever my roommate was, he or she was not here, which was fortunate as i was still completely naked. i got up and went to the bathroom that connected the room to the other one in the suite, locking both doors. i examined myself in the mirror. curiously, the first thing i noticed was that i was probably about a full foot shorter, perhaps about 5'3". yes, i was indeed a girl. small breasts, but breasts nonetheless. blond hair, about shoulder-length, and a blond patch between my legs. i sat on the edge of the tub and spread my legs to examine that patch a little closer. i pulled the lips apart and saw what looked an awful lot like every other cunt i had ever seen. inner lips, a hole, and the clit up top with its little hood. "that certainly isn't my dick," i said to myself. at the thought of my dick, i immediately felt a warmth between my legs. my nipples became hard, and my pussy started to wet itself. i rushed out of the bathroom and covered myself with the sheet from my bed to hide my nakedness from view, and keep from masturbating. i decided to watch some tv to take my mind off of sex. the only problem with that is that it made me hornier. even though they were fully clothed, my male mind reacted to the women on television, and my female body reacted to the men. my sex drive was much higher than it had ever been, even as a 15-year-old boy. there was nothing particularly sexual about the shows i was watching, but they were making me more turned on than ever just from looking at the people in them. my pussy juice was flowing and my nipples were so hard they ached. i started masturbating without ever thinking about it. after a while, i just realized that one hand was between my legs stroking the outside of my lips, and the other was cupping one of my tits. my whole crotch was slippery as i rubbed my slippery finger against up and down my slit. i concentrated on my clit, because it gave the most sensation. it felt kind of like the head of my dick, but the sensations were so much more intense. with my other hand, i explored the sensation of stroking my tits. i rolled my tiny, hard nipples around with my palm, then squeezed them. after a few minutes of this, i began to feel a hotter feeling, starting in my crotch, but spreading throughout my entire body. it slowly intensified, becoming this tingling sort of ecstasy, into my first female orgasm. i could feel my nipples clench up even tighter. i lay there, breathing heavy, for a few moments until i realized that i was still horny. i thought about how i used to jack off my dick or fuck my girlfriends, and how i would be completely satisfied (and usually sleeping) five minutes after i came. i still would rather be a man, but womanhood had at least some advantages. or maybe it was just the effects of whatever had been done to my body; the female voice had said something about my sex drive increasing. the thought of jacking off my dick made me even hornier. i was taken by a sudden need to be penetrated. i reached down into my still soaking, hot, wet pussy and spread the lips. i slipped my index finger into my sopping wet hole up to the first joint and left it there for a moment, just savoring the feel of being penetrated. soon, however, i lost all control and slammed it in all the way, moving it in and out as fast as i could, feeling my finger rubbing up against my inner walls. it felt kind of like stroking my dick, but in reverse. i put my middle finger inside myself also, finding that i was kind of tight (not surprisingly.) my fingers were slipping in and out of my new cunt, as my palm rubbed up against my clit at the end of each stroke. after a few minutes of this i came again, more violently than the first time. i thrashed back and forth on the bed and started to scream, but i didn't stop fingering myself. instead, i took my left hand from it's place on my right breast, and swished it around my clit for a while, still pumping my hole with my right. that felt good, and i kept it up for a while, but what i really wanted was to feel another kind of penetration, so as soon as i had my finger good and lubricated, i turned over. supporting myself on my knees and head, i stuck my little ass way up into the air, spreading my cheeks wide, and while still pumping my pussy as fast as i could, i started to slowly insert the index finger of my other hand into my asshole. at first, it hurt a bit, so i took my time and eased it in slowly. once i had it in to the hilt, i started to pump it very slowly in and out. my ass was even tighter than my (virgin!) pussy, so even using only one finger i felt completely full back there. i pumped faster and faster, realizing that this sensation was nearly as good, if somewhat different, than the one i was causing in my cunt. i was soon pumping my pussy and asshole for all i was worth, causing loud slapping and squishing sounds that would have been more audible if i hadn't been moaning so loudly. the warm feeling began again, centering both on my pussy and my asshole, and then i had my third female orgasm. i must have fallen asleep, as the next thing i remember is hearing my new roommate entering the room. at least it was a girl. i was wet at once when i saw her but i didn't drag her down on the carpet immediately and[censored]her, as i might have done had it been a man. she introduced herself as tiffany, and i blurted out my real name and was thankful that it's chris, if it were something more obviously male i would have had some explaining to do. as i said, as soon as she walked in my cunt was soaking and my nipples were hard again (those things were perpetually hard.) that would probably have been true no matter what she looked like, considering the shape my sex drive was in, but the fact that she was gorgeous didn't help matters. she was an inch or two taller than i was (now. i would have towered over her when i was still a man,) and she had hair about two shades lighter than my new color, and longer. her tits were gigantic, there's no other way to describe them (i found out later that her bra size was an e cup, and she had trouble shopping for anything that large,) and the rest of her was thin, but still with nice curves and wide hips. the only problem was that i was still naked. luckily, i had moved around in my sleep and covered myself with the sheet, but it was thin and white and i was pretty sure it didn't hide anything. i was trying to figure out a way to get up and dressed without tiffany finding out how naked and horny i was at the sight of her, when she saved me the trouble. she surprised me, actually. most of the lesbians i had met looked like men, some complete with facial hair, so it never occurred to me (in the first five minutes of our acquaintance) that tiffany would be one. she wasn't actually, she was bisexual, but i didn't find that out until later. she came over to my bed and gently pulled the sheet down. her gaze went first to my crotch, which was glistening, then to my nipples, which were starting to ache again. "thought so," she said softly, grinning. then she took off her shirt, unclasped her bra, and lifted one of those huge, gravity-defying tits up. i didn't need another invitation; i started to suck it. i had always loved breasts as a man, and it was good to know that one thing at least had not changed. i licked her nipple around and around, occasionally grasping it lightly between my teeth. she moaned quietly as she unbuttoned her jeans. getting up on her hands and knees, wearing only a pair of thong bikini underwear that rode up between her cheeks, she stuck her ass in the air and spread my legs. going down onto her elbow (with her tits rubbing against the mattress) she started to rub her thumb along my slit. she was deliberately teasing me, just brushing the clit, getting me hotter and wetter with each stroke. after a while, she lowered her mouth to my new cunt. if i had known how good it felt to have your pussy licked, i would have done it to more girls when i was still a man. she licked up and down the length of my cunt, like she had been doing with her thumb, but her tongue was so much more slippery and pliant. she barely brushed my clit, then pushed her tongue as far as she could into my hole and fucked me with it like it was a dick. i decided that, as long as i was a woman, i loved the feel of my cunt being slippery and having it penetrated. then she stopped that, and started sucking my clit. this was too much, and i came. when i was done moaning, i opened my eyes to see that tiffany had strapped on a ten-inch dildo over her panties. i was of two minds with regards to that: my male side was disgusted at having sex with anything resembling a dick, but my female body was more than willing. i decided that, since this wasn't a man but only a woman with a dildo, it would be all right. i wanted to be taken doggy style, so that at least i wouldn't have to see it, so i turned over onto my knees and elbows, noticing as i did that my tits didn't hang down to touch the bed like tiffany's had. i felt her move the head of the huge dildo around at the entrance to my pussy to lubricate it, then slowly she pushed it into me. i nearly cried out from pain at first, as the largest thing that had been in my pussy so far was my two fingers, but she stuck it in slowly, going an inch or so and waiting for me to relax, so eventually she had almost the full ten inches in. then she started to buck her hips slowly back and forth. i was in ecstasy. penetration was what this body was set up to get pleasure from, and i loved it. my inner walls, having loosened to accommodate this intruder, tightened again to maximize my pleasure. tiffany reached around the front of me to rub my clittie while fucking my pussy. after a few minutes of this, i had lost my reservations about seeing the dildo going into my cunt, and i made her stop and lay back on the bed. i let her lay there for a minute, letting our anticipation build, as i kneeled next to her fingering my pussy and cupping one of my tits. i was glad they weren't as large as tiffany's; breasts that big must be unwieldy. then, i straddled my new lesbian lover and impaled myself on the dildo sticking up from her midsection in one thrust. i thrashed around on top of her, manipulating both my tits with my hands, for about five minutes, until she came from the friction. i kept going, though, leaning over to kiss her mouth and neck, and rubbing my small, a cup breasts against her ridiculously larger ones. just as i was about to come, she pushed me off of her, and sat up. "do you like it in the ass?" she whispered to me. i didn't reply, i just grinned and nodded, and i got back on my hands and knees again, but this time she put the dildo, even more slowly and gently, into my other opening. this was a bit weirder for me, because it occurred to me that i could conceivably have done this even when i was a guy, but it felt too good to stop. i was so horny that i didn't notice any pain at all, and soon tiffany was ramming that dildo in and out of my asshole at top speed. again, she reached around to finger my cunt, her fingers slipping in and out of that hole as her dildo assaulted the rear opening. i came quickly, and she came again from the friction immediately after. i wanted more, but tiffany was worn out, so we fell asleep on the bed, in each other's arms. i woke up long before tiff, having had a long nap before she showed up, and went into the bathroom to shower and wash the sweat and pussy juice off of me. i made sure to lock the door behind me, as i had one other plan in the bathroom. after i took a hot shower, luxuriating in the feel of the water splashing over my tits, i got to thinking. i would still rather be a man, but unless i could find whoever did this to me, i would have to remain a girl for a while, and at least i had a great supply of lesbian sex. that was something that had always turned me on as a man, and it was even more fun in reality than in fantasy, and as a participant than as a spectator. the other thing that i had noticed about female sex was that i really liked the sensation of my cunt being so wet that it was completely slippery, inside and out. the one thing standing in the way of that was all the hair around either side of my slit, so i decided to shave the hair off of my lips to make them more smooth and slippery. i looked under the sink, searching for a razor or something, and came out instead with a pair of electric clippers. what would tiff do with these? i shrugged and decided these would do to start with. i sat down on the floor and spread my legs as wide as possible. it still looked extremely strange to see a cunt there instead of my dick, but after the sex i had had, i was starting to get used to it. i turned the clippers on and started shaving, way back on what was actually the very bottoms of my ass cheeks, slowly working my way up towards my cunt. the clippers, cold to start with, started to warm up as i reached my cuntlips, and the vibration was turning me on. my pussy, always on a hair trigger, got wet again, and my nipples, already hard (of course) got even harder. i had shaved my lips, but i didn't want the sensation to stop, so i continued, shaving as slowly as possible, to trim the sparse hairs around on either side of my patch of pubic hair. i also removed the sparse hairs across the top of my mound, evening out my growth into a triangle at the top of my slit. i still didn't want to stop, so i went around the triangle again, trimming it in a bit on the sides and down by about an inch across the top. i was still enjoying myself, so i went around the triangle again, reducing it to a little circle, about one inch around and about one half inch above my slit. looking at the ridiculously small patch of pubic hair i had left and feeling a little sheepish, i decided i might as well go all the way, and i removed the last of my pubes. i ran my finger across the top of my mound, intending to masturbate, and found that i could still feel the stubble. to remedy that, i stepped back into the shower and, using shampoo as a cream, used tiff's leg razor to gently remove all trace of pubic hair from my crotch. the shampoo made me really slick, but i decided that i didn't need any help, so i got out and dried myself off. looking in the mirror i realized that, because my pubic hair had been blond, the follicles were now invisible. with my tiny breasts, completely smooth pussy, and young looking face, i could have passed for fifteen. a very horny fifteen year old, though, as i discovered as i felt the smoothness of my newly shaven twat. i sank down onto the carpet and started to finger myself again. my right hand pounding my cunt, i wet my left in my pussy juices and slowly inserted it into my asshole again. it was much easier now that tiffany had loosened me up, but it felt just as good. i was moaning as quietly as possible, so as not to wake tiff, and rapidly approaching orgasm when i heard the jiggling of a doorknob. too late, i realized that i had forgotten to lock the door to the other room in the suite. while i was lying there, two fingers in my pussy and one stuck up my ass, the door opened and in walked a guy, wearing just a pair of boxers. i came to the conclusion that this was a co-ed dorm. while i was lying there, both hands still inside myself, i stared between my upthrust knees at his crotch. i had one of the hardest decisions of my life. my mind abhorred the idea of sex with a man, but as soon as he walked in my pussy had gotten even wetter and my nipples had become so hard that i moaned in pain and arousal. i couldn't take my eyes off his crotch, tracing the outline of the dick that i knew was concealed there. i tried to resist, but with what had been done to me i never really had a chance. i tore my gaze away from his crotch to see the surprised and dazed look on his face. i grinned at him, then got to my knees and pulled his boxers to his ankles. in that moment, i needed cum, anyway i could get it. i took his already hard and quite thick eight inch cock into my mouth and administered my first blowjob. i took as much as possible into my mouth, cramming it in as best i could, and then removed it and licked up and down the shaft. after alternating these for about three minutes, i took the head in my mouth and sucked as hard as i could, while pumping the shaft with my hand. he came into my mouth, and i swallowed it all, my gag reflex forced down by the chemical need for sperm that had been instilled in me. immediately after ingesting the cum, i began to feel strange. i felt dazed, and a tingling sensation kind of like the beginning of an orgasm enveloped my whole body, centering on my breasts and my lower torso. also, i immediately felt hornier and my craving for cum increased immensely, so i pushed this guy (we still hadn't exchanged a word, let alone names) back into his room and onto his bed. i knew he would immediately feel like falling asleep, but i had other needs, so i again sucked his cock until he had another raging hardon. then i got on my hands and knees (so at least i could avoid kissing him,) and he took the hint and pushed into me. unlike tiffany, he had very little finesse, he just plunged in. luckily, i was already quite wet and stretched out, and i didn't really want finesse anyway, i just needed his cum. it did feel good, though, to be filled with warm flesh instead of just molded plastic. i pushed my butt back against him, intensifying his strokes. he pounded my pussy for about five minutes, then shot his wad into me. once again, i turned around and started to suck him off to get him hard. it took longer this time, and i had to put some effort into it. eventually, though, he was hard enough and i turned back around, presenting my shaved little pussy to be fucked. he went to it more slowly, but after almost ten minutes i was rewarded with another load. my cunt felt warm and sticky, and the strange feeling that had come over me after he came in my mouth was getting stronger, intensifying even more in my breasts and crotch. when i tried to get him hard again, i was unable. i took his limp cock into my mouth and swirled my tongue around it, sucking as hard as i could, but even after about five minutes of this, he still couldn't get it up. i was desperate. i needed more cum, and my mind was racing to find some way of inducing an erection. suddenly, i thought of one fantasy that most guys had but few girls will ever let them try. "would you like to fuck my ass?" were my first words to him. suddenly, his cock was stirring, and as i sucked it, it blossomed into a full blown hardon. i turned around once again, this time presenting not my smooth pussy but my asshole to be fucked. the male part of me that was rebelling against all this was horrified, but my unbelievably horny female body overruled me, and my craving for cum ended any chance of resisting this final degradation. he slipped into my asshole and i was too filled with pleasure to stop. he pumped me for the longest time yet, more than fifteen minutes, and i couldn't help loving every minute of it. my ass was so tight that it felt like i could feel every vein on his cock pushing in and out of me. i reached down between my legs and finger fucked myself while he was pummeling my asshole. i had just come for the third time when he shot his fourth wad deep up into my abdomen. he pulled out and rolled over, passing out almost immediately. i didn't want to suck his cock after it had been in my ass, so i rolled off the bed and stood up. i realized in doing so that i had a lot more weight on my chest. looking down at myself confirmed it. i went back into the bathroom to look in the mirror. my pussy was still bald, but i couldn't be mistaken for a teenager anymore. my tits had somehow grown to the size of baseballs, and were nearly as spherical. the fact that they hadn't been resisting years of gravity made them almost impossibly round and perky. my tiny nipples (still hard!) jutted out from the upper half of my growing breasts. my hips were also wider, and my waist maybe a bit skinnier, but nothing as radical as the breast growth. i now knew what that voice had meant when it said that cum would cause physical changes. all this staring at my body had made me horny again, so i went back to my room, got tiffany's dildo, and laid down on the other bed. i spread my legs as wide as i could, and plunged the dildo into myself all the way on the first stroke. i fucked myself furiously, bringing my little bald cunt to an orgasm five or six times in succession before i passed out from exhaustion. i woke the next day again thinking, "what a strange dream," but today i didn't even have to move to feel the extra weight on my chest and my pussy, still full of tiffany's dildo, to realize that this was reality. i opened my eyes and looked down at my breasts. yes, not only was i still a girl, but it looked like my tits were going to blow up like balloons every time i came into contact with cum. "ah well," i thought, "i'll just have to keep self control and keep myself satiated with lots of lesbian sex with tiffany." at the thought of tiff, i turned to look at the other bed. she was still there, asleep on her back wearing only those black thong panties with her tits sticking up like twin mountains growing out of her chest. i hoped that mine never got that large. looking at tiffany was making me horny, and as i was supposed to be practicing self control, i went back into the bathroom to take a cold shower. on the way, i checked the dresser that tiffany had not emptied her clothes into, and found that it was stocked not with my clothes but with women's clothes that would probably fit me now. most of them were just jeans and t shirts, so i didn't worry that i'd feel like i was in drag, but the underwear bothered me. all the bottoms were thong panties even skimpier than tiffany's and there were lots of bras in there, in varying sizes. they went from a and b (which i would never need now,) up through c, which was what i figured i was currently, and up past tiffany's e cup size all the way to an h cup that must have been custom made; i'd never heard of such a thing. it was huge, designed to hold tits the size of watermelons cut in half. i decided that with my new resolve and self control, i'd never need such a thing. i also decided that there was no need for me to dress up in these girls clothes quite yet. after all, i had been naked all day yesterday, so a few more hours couldn't hurt me. i went into the bathroom and started the shower. while washing myself, i thought about how i could find whoever had done this to me, and turn myself back into a man. sex as a woman was enjoyable, but i had been born a man and that was the way things were meant to be. however, i really had no clues as to who was responsible for my current state. i felt a wave of depression rushing towards me, but then realized that whoever did this wouldn't just ignore me now that it was done. they had gone to all the trouble to wake me up to gloat about it, so they would probably make contact with me again. the only thing i could do for now was to be inconspicuous and wait until i had more information. about this time i noticed that the cold shower wasn't doing much to offset my horniness. it made my constantly hard nipples even harder, and that led to my cunt getting wet. for the past few minutes, i had been absently fingering myself. i put a stop to that immediately. i got out of the shower and dried off, and was about to go get dressed when i heard the jiggling of the doorhandle to the other room in the suite. i fought the urge to open it, but then i told myself that i should at least exchange names with the man i had fucked last night, so i opened the door just wide enough to poke my head out. i saw a completely different boy's face. "uh, hello," he said, embarrassed. "my name's greg. um, i guess we're suite-mates." "i'm chris," i said. "and your roommate?" "oh, you met him?" he replied. "his name's ian." i saw greg's face turn red and realized that i had unconsciously opened the door wide enough to give him a good view of my shaved pussy and one breast. i also realized that i wanted to open the door even wider, tear his clothes off, and fuck him. i fought with myself for a moment, but the thought of cum had entered my head again, and my self control was not nearly as strong as i had thought before. i pushed open the door and stepped through. greg started to try at least to gain his composure, and as it was obvious to both of us what was happening, he pulled off his shorts for me. i saw to my great surprise that his cock was shaved as bare as my pussy. i had heard of a few girls doing that, but never a guy. i realized, though, that it turned me on. actually, by now almost everything turned me on, but in any case it felt good as i dropped to my knees and took greg into my mouth as he sat on the edge of the bed. his dick was slicker than ian's, and longer, nearly as long as tiffany's dildo. but it was the slickness that i really enjoyed, as i took as much as i could into my mouth and wrapped my hand around the rest, feeling the smooth, hairless skin around the base. i pumped my face back and forth on his dick, and there was enough extra that i couldn't swallow that i was also jacking him off with my hand. i pulled my mouth off of him, and just licked the tip in circles around the hole, jerking the shaft with both my hands now. then i had an urge to take it all in, so i let go with both my hands and just tried to swallow all of his dick. i couldn't get it all down. after a few minutes of trying, my jaw was getting sore, so i just sat there and looked at this hairless cock while jacking it off in my hand. after a minute or two of this, greg started to moan and buck his hips, and i knew that his orgasm was about to hit. i jacked him even faster, but as the first bit of cum started to appear at the tip, i was overtaken with a craving. i needed every last drop i could get. i knew what would happen if i touched any of his cum, but i couldn't help myself. suddenly, i was rationalizing. my tits would only get a little bit bigger from one dose of cum, and that wasn't so bad. i took the head in my mouth and pumped for all i was worth, sucking his cum down my throat. i kept jacking and sucking even after his orgasm finished, craving every drop i could get. that tingly feeling immediately sprung up in my tits and midsection, but i knew it would. i was still horny though, and suddenly it seemed that just one load of cum wouldn't be enough. i continued to suck greg back to an erection, rationalizing that i would have him pull out at the last moment and spurt onto the bed. as soon as i had sucked greg's cock back to an erection, i stood up, ready to push him back onto the bed and mount his cock, but he stood up and entered me still standing up, face to face. he then reached around behind me, grabbed my ass cheeks, and lifted me up, with his cock still filling me, spinning me around and landing us in the bed, with him on top. this was the very position i was trying to avoid, as i did not want to be face to face with a man, fucking him. now that i was actually in the situation, though, with his big cock sliding in and out of my slick, shaved pussy, i found i couldn't work too hard at changing position. i still didn't want to kiss him, so i stretched my neck up, getting my lips out of the way. he kissed my neck, but i decided i could live with that. i just concentrated to the sensations he was causing in my body. it felt wonderful! my pussy was filled and stretched with his cock, and as he thrust in and out i could feel the tip of him butting against my rear wall. his hands were playing with my tits, cupping them, kneading them, and playing with my nipples as he continued to fuck me. i loved having my breasts played with! after playing with my breasts for a few minutes, constantly fucking me at a furious pace, greg reached under my ass and grabbed my cheeks. at first, i think he just wanted more leverage, and he used his arms to pull my pussy more forcefully onto his cock. in the process, he was spreading my ass cheeks as wide as they'd go, and an idea occurred to him. he wet his finger with the pussy juice that was freely flowing down my ass crack and then inserted it into my asshole. this was not a new sensation to me, but it should be obvious if you've read this far that it was one i enjoyed very much. i bucked my hips back and forth violently. every time i pushed forward, his cock pushed into my pussy, and each time i pulled back down, his finger invaded my asshole. i increased my bucking motion, and started to orgasm. i thrashed my head back and forth, uttering something halfway between a moan and a scream, and bucked my hips even faster onto his cock and his finger. just as my orgasm was subsiding, his began, and he shot his wad deep up into my cunt. within a few seconds, i had flipped him over off of me, and was slurping my still hot pussy juice off of his softening dick. it stopped softening shortly, and started to grow into an erection again. after he was hard again, i moved up along his body and positioned myself over his cock. slowly, so as to tease myself with the pleasure, i lowered myself down onto his cock. when he had penetrated my completely, i started to roll my hips, ever so slightly, which caused his dick in my pussy to move against the inner walls just a little bit. without ever intending to increase the motion, i sped up and intensified, just from naturally wanting to feel more of it. soon i was bouncing up and down on his cock as hard as i could. i noticed that the motion was kind of uncomfortable for my tits, so i reached up to press them against my chest. they were already noticeably bigger! i pressed them against my chest and bounced up and down, but after a while, i didn't want to use my hands only for this, so i leaned forward (making sure to keep my lips still out of reach) and rested my breasts against his chest. i didn't have to bend forward as far as i would have an hour ago. after fucking greg like that for a few minutes, i felt the bed shift. i felt hands spreading my ass cheeks, and a warm, hard dick slipping into my asshole. i had forgotten about ian, the guy i had fucked the night before. apparently, our fucking and my screaming had woke him up, and he couldn't restrain himself from fucking my ass again. i reveled in the sensation of having both my holes filled with hot, thrusting cock. i never would have believed myself capable of being such a nymphomaniac, but i told myself that the chemical changes that had been forced on me were responsible, and it was not my fault. my conscience soothed, i was able to concentrate on enjoying it! i lay there between these two dicks, unable to do anything except let them fuck me. greg fucked my pussy while ian pounded my asshole, and the varied sensation when they would get out of sync with each other pleasured me just as much as the feeling of being doubly fucked. i orgasmed once, and experienced something only women can: the orgasm didn't stop, it just got stronger and weaker in waves. i lost all conception of time; they might have fucked me like that for fifteen minutes, or it might have been a week, all i know was that i was in ecstasy and i never wanted it to stop. after some unmeasurable time, however, ian shot his load into my asshole, and pulled out. greg orgasmed a moment later, and collapsed onto the bed, exhausted. i had just received a double load of cum, and the tingling in my breasts increased accordingly. looking down, i imagined that i could almost see them growing. i still craved cum, however, and as it looked like greg was down for the count, ian was the only supply. unfortunately, he had just fucked me in my ass, and i didn't want to suck his dick. instead, i pushed him back onto the bed and kneeled in front of him. i reached down to my bald cunt, and started to finger fuck myself, all the while whispering how i wished he was hard again so he could fuck me. that caused his cock to perk up somewhat, but it wasn't yet all the way hard, so i grasped one of my breasts and lifted it up as far as i could. i found, as i had suspected, that it was now large enough for me to get the nipple into my mouth. i kneeled on the bed, sucking my own tit and fingering my pussy in front of this guy like a cock crazed slut. i realized that that description was probably accurate, i was a cock crazedslut, but as his cock stiffened to full erection, i simply didn't care. i didn't want him to stick his dick into my pussy. i'd heard you could catch some diseases that way, so i turned over onto my hands and knees and told him to stick his dick back up my ass. i noticed that my breasts hung down significantly lower than they had before, and i actually enjoyed the fact! i was fucking guys left and right, their cum was making my tits grow out of control, and i couldn't help but enjoy it, it felt so good! ian fucked my ass with all the excitement he had shown last night. more, in fact, as he reached around the front of me and played with my breasts. i don't know what he thought of my sudden growth, but at least it kept my hands free, one for support and one to play with my slick slit. i rubbed my fingers up and down my lips as ian's dick plunged in and out of my ass, both of us growing closer to orgasm. i reached it first, and though it wasn't one of those endless ones like the last one, it was excruciatingly good. just a few strokes after my orgasm was subsiding, ian pulled back on my breasts, burying his cock all the way up my asshole, and shot his thick white cum up my anus. then he rolled over and fell back asleep. i got up and went back into the bathroom that connected our rooms, looking in the mirror. i was amazed at the changes. my hips were obviously inches wider, but the most noticeable difference was in my tits. they were now the size of ripened cantaloupes! i guessed now i'd never need the c or d cup bras either, it looked as if i'd jumped straight to the dd's! they didn't hang or sag, though. they were almost perfectly round and rode as high and perkily as they had when they were half the size. with my huge tits, wide hips, and bare shaved cunt, i looked like the sexiest girl i had ever seen! i went back into my room to wake tiffany and see what she thought of the changes. tiffany was still asleep, as i expected somewhat. i had worn her out the night before, and it was actually only eight thirty in the morning now, so it wasn't surprising that she slept right through my screaming sex session with the boys next door. i didn't intend her to sleep too much longer though, and i wanted to wake her up in a good mood. i looked at her, still lying there in only her g string, her gigantic tits standing up on her chest. i was glad that at least mine weren't that big ("yet," a small part of my mind said.) it comforted me that she still made me horny. i still was attracted to girls, and if that made me bisexual, it was only because my body was beyond my control and so strongly oriented on men. i leaned over and, while she continued to sleep, began to lick her breasts. i licked around the bottoms, lifting them up slightly to lick the area that had been folded over, and worked my way up to the nipples. i sucked these very gently, alternating from one to the other, wanting tiffany to wake up slowly to the sensation. she stirred and moaned a but, but wasn't awake, so i decided to give her a stronger sensation. slowly, i worked the sides of her g string down her hips, pulling her panties slowly down her legs. when i had removed her underwear, i gently and slowly spread her legs, and settled my head down between them. as long as i could, i took a good look at tiffany's little blond pussy. it looked like she did shave the sides and top of her pubic hair in by a couple of inches, as she only had three or four square inches of hair at the top of her slit, and none on the actual lips. i was glad about that, because i had never really liked to lick excessively hairy cunts. other than that, she had a normal looking, but very soft and pretty, little mound. i leaned down between her legs and brushed my tongue slowly from the very bottom of her slit, almost on the asshole, up to the clit, then back down again. back and forth, back and forth i licked, and tiffany started to stir a bit more, moaning out louder. i concentrated on her clit for a moment, and she cried out softly. i knew she was awake when she reached up to stroke my hair, and grasped my head gently and pulled it closer to her pussy. "lick my clit again," she said. "say please," i replied, teasingly. "please," she said, "lick my pussy. stroke my clit with your tongue. i need it! oh! yes! like that!" after that, she didn't have much more to say, but she made a bit of noise. in my opinion, that's probably a good way to wake up. i remember hoping she returned the favor for me some time. after tiff had finished cumming, she sat up and licked her pussy juice off of my face. although i wouldn't kiss greg and ian, i had no such compunctions when it came to tiffany, and we sat there face to face on the bed for a while, kissing and stroking up and down each others bodies. i slid my hands down to her hips as she reached around behind me to grab my ass cheeks and knead them for a while. i slid my hands up to her chest to squeeze her nipples, twisting them gently, and she started to do the same to me. "what the hell is this!?!?" she nearly screamed. "uh, i'm not really sure," i said. it suddenly occurred to me that i had no explanation for my rapid growth in the chest and hips. i decided to tell at least part of the truth. "i don't understand how this happened," i explained. that, at least was true. "i noticed they were like this as soon as i finished..." i trailed off, not wanting to admit i had fucked and sucked two guys i had never met before. "as soon as you finished what?" she asked, curiously. "well..." i started. "screwing the guys in the next room, to put it bluntly." "guys?" she asked. "as in 'more than one guy'?" "two, actually." "why didn't you wake me?" she said. "greedy. you didn't want to share." we laughed at that, and that led, by easy steps, to us kissing and stroking each other again, my breast growth temporarily forgotten. i decided that if she asked again, i would stick to the truth: that i really didn't understand what had happened. i knew that i was going to have to stop it from happening again, though. after tiffany and i 69'ed for a while, and we both had several great orgasms, she said: "whoa, that's enough for a while. you may be a little nymphomaniac, and i really don't mind, but i really need to get to class. have you showered yet, or do you mind if i go first?" while she was in the shower, i found my own class schedule in my dresser. the classes here the same as the ones i had signed up for, but the name on the schedule was "christine taylor" instead of "christopher." my wallet was also in the dresser, and my license had been changed similarly. whoever had done this to me was thorough. i started to get dressed. i put on the woman's underwear for the first time (after running around three rooms naked for over twenty four hours, i realized) and felt the black thong underwear pull up into the crack of my ass. it was uncomfortable at first, but i decided that after all the things i'd had up there in the last day, i really shouldn't complain. actually, after i got used to it, it felt pretty good as it kept my asscheeks slightly spread and rubbed against my sensitive little asshole, but it didn't help my chronic horniness. the bra was even more embarrassing. i'd seen girls put them on often enough, so that wasn't a problem, but all the styles i had been provided with here really sexy. i picked out one of the dd sized ones, black to match my panties, and put it on. it lifted my tits up and held them back against my chest more, and that made me hornier. also, it was one of those half-cup styles that held them up but didn't cover the nipples, so my perpetually hard little nubs stuck out into the cold air enticingly. i covered myself with jeans and a black t shirt, wanting to avoid the dresses and skirts in the dresser, and found some shoes. i left before tiffany even got out of the shower, even though my first class didn't start for more than an hour. i was nervous as hell to be seen outside my room as a girl, and i didn't think i'd be able to get up the courage if i waited too long. as i walked across the campus, i was acutely aware of the sensations of my body. my hips swung in a wider arc, my tits shifted as i walked, and my nipples were constantly brushing up against the inside of my t shirt, which kept them even harder than normal. i looked down at my chest, and saw that they were very clearly visible through my shirt. i was horny as hell, and as i walked around and saw all the men staring at me, i knew i had to do something about it. i was almost horny enough to pull one of them into a clump of bushes and fuck him. or at least suck his dick; my craving for cum was back in force. i could feel a little pain in my stomach, and i just knew that a load of cum would make it go away. i exerted all the willpower i could, and kept my eyes forward as i thought of a plan. i walked as directly as possible to a little shop just off of campus, one that sold "adult books & sex aids." i went inside, and looked around for the dildos. the sleazy looking fat guy behind the counter was staring at my tits the whole time. i found what i was looking for on a shelf in the back of the store. down at the bottom was a little five inch vibrator. as i bent over to get it, my huge tits fell out over the top the half cup bra i was wearing. i knew it was obvious from the way the guy behind the counter was staring at me and almost salivating as i stood up and readjusted myself. i took the dildo up to the counter and bought it, as well as some spare batteries and some condoms. the greasy guy's eyes never left my breasts, even while he was making change. as i walked outside, i shuddered. i was a man, dammit! i didn't enjoy wearing these woman's clothes, i didn't really want breasts or a pussy (though i had to admit to myself that they were capable of giving me some really wonderful sensations.) nonetheless, while i liked the way they felt, and would even have liked the way they looked if it had been on someone else, i really wanted to be able to walk around as a man again. that sleazy guy behind the counter disgusted me. why couldn't he keep his eyes to himself?! i decided that i needed to get a cock back between my legs. that thought led me in the wrong direction though, as i started to think about getting greg's or ian's cock back between my legs. my pussy was starting to soak through my underwear, and that reminded me of the vibrator i had just purchased. i was back on campus now, so i headed for the nearest bathrooms. my head down, i nearly walked into the men's room before i realized my mistake, and then i had to restrain myself from going in anyway. my craving for cum was so bad that i considered walking right in and taking some guy's cock in my mouth as he turned around from the urinals. after fighting with myself for nearly fifteen seconds, i turned reluctantly and headed for the women's room. it helped that i had another option. when i got inside a stall, i pulled down my pants and sat on the toilet. i relieved myself as i pulled the dildo out of my backpack, then i turned it on and placed it right up against my clit. the sensation was very similar to what i had enjoyed from the clippers as i was shaving my pussy bald, but i would never have applied the electric shaver this directly to my sensitive clit. the feeling of the vibrator there was spectacular. i rubbed it up and down my slit and inserted it into my hole, but i always came back to rubbing my clit with the tip. i orgasmed at least three times in ten minutes, being as quiet as possible because girls were coming in and out of the bathroom. i couldn't contain myself from moaning slightly though, and i'm sure they had some idea what was going on from the looks i received when i left the stall. after i had cum three or four times, i was by no means satisfied (i hadn't been completely un-horny since i was changed into a woman,) i wasn't as desperately aroused as i had been when i walked into the bathroom. i left the vibrator on and pushed it completely up into my pussy, pulling my thong panties up to hold it in. i adjusted my clothing and left, ignoring the stares of girls who had heard the buzzing and moaning from my stall. it worked! every time i saw a guy and craved his dick, i just squeezed on the vibrator in my pussy and concentrated on the sensations it caused there, and that distracted me sufficiently. i made it to class, sat down in the back, and pushed all my weight down on the vibrator, impaling myself on it. i wiggled in my seat through the whole class, but i even managed to get some notes down, in between orgasms. as soon as class ended, i rushed directly back to my dorm. i needed some sex, and i needed it now! i just hoped tiffany was back from her class.

part 2

the walk back to my dorm was not an easy one. the dildo buzzing away in my soaking pussy made it possible for me to appear in public without raping every guy i saw, but it had it's own downside. simply put, it felt too good! being that i went to a large state university, it took me almost a half hour to walk from one side of campus, where my class was, to the other side, where my dorm was. inside of that half hour, i came three times. while i had been sitting in class, i had had only four orgasms in three hours. the difference was the extra sensation of walking. as i said before, it made my whole body react. my nipples brushed up against the inside of my t shirt, and were again so hard it was painful. the gentle rolling of my hips as i walked accentuated the sensations coming from the buzzing in my twat, and as soon as i noticed that, i began to intensify the hip motion as i walked. soon, i was rolling my hips like a belly dancer as i walked along, just because it felt sooo good! needless to say, walking across a college campus looking like raw sex gets you some appreciative stares from college guys, especially if you have blond hair, wide hips, a nice ass, 36dd breasts, and (i won't be modest) a pretty face. i'm ashamed to admit, i enjoyed being looked at so lustfully. i remember being surprised at that reaction, so soon after i had been so pissed at the guy from the porn shop for staring at my tits. was i beginning to turn gay? i wondered. no, i decided, it was just that i was so much hornier now, my female body was overriding my male mind and making me lick my lips and smile back at the guys as i passed them. their stares just made me hornier, which made me accentuate my walk more, and the whole thing fed on itself, spinning off out of control like feedback. this particular walk back to the dorm took longer than a half hour, because i had to stop three times and sit down on a bench. i didn't really think i could keep walking normally while in the throes of an orgasm. i didn't think i could have done that as a man, but orgasms as a woman were even more intense, and spread throughout my entire body. actually, i thought as i sat down breathing heavily and came for the third time, these orgasms were even stronger than the first i'd had as a woman. the voice had told me that each time i orgasmed i would get hornier. i guess this was just one more aspect of the change. i thought more about the change as i sat there, wanting to wait a bit more before i tried to get up and walk. i had been a normal man before i woke up in that room, tied to the bed and with a new pussy and some small tits. now, my tits were 36dd and growing every time i touched cum. soon i would run out of letters. i wondered why anyone would want to do this to me? it couldn't be revenge, nobody really had any reason to have a grudge against me. i didn't even know who had done it. i only hoped that i was right, that whoever it was would make contact with me to keep tabs on my progress, and that i could get some information then that would help me force them to turn me back into a man. i really wasn't into being a woman. the sexual sensations were the only thing it had going for it. i had avoided bothering with makeup, i had washed my hair but not done anything with it (i was glad it was fairly short.) i really wasn't one of those guys who got off on dressing like a girl. this morning while getting dressed i had consciously put on jeans and a t shirt, about the most non gender specific outfit you could wear. my sexy underwear was not my fault. all the underwear my unknown persecutor had supplied for me was skimpy and sexy, consisting entirely of thong bikini panties and half cup bras in sizes reaching up to a custom made h cup (which implied something i'd rather not think about.) the best i could do this morning was to choose black underwear instead of the pink. all these thoughts were running through my head as i finally reached my dorm and started climbing the steps to my room. i let myself in, and was immediately disappointed to find that tiffany wasn't there. i was so horny! i thought about my options for a moment, and then realized that i really had no choice. i tried to fight it, but i found myself drawn inexorably to the bathroom that divided our room from ian and greg's. at least i had the presence of mind to grab the condoms from my backpack as i was swept along. as i quietly opened the bathroom door, i heard the shower. peeking around the shower curtain, i saw greg standing under the shower spray with his back to the nozzle, shielding his front from the spray. he didn't see me, so intent was he on what he was doing. i thought back to this morning, when i had seduced greg and found that he kept his cock shaved as bare as my slit. i had found that unbelievably arousing (actually, since i had been changed into a woman, i found almost everything unbelievable arousing.) now, as i watched, he was carefully touching up his shaving job, with his cock lathered up in soap and his razor sliding softly over the smooth skin. apparently, he found it as arousing as i did, because his cock was standing up to a full erection. as i watched, he stopped shaving for a moment and started to stroke his shaft slowly up and down, closing his eyes and opening his mouth into a big 'o' of pleasure. he soon returned to the business at hand, however, and continued shaving his cock and balls until he was apparently satisfied that they were completely smooth. then he took his cock in hand and started to jack off in earnest. i didn't want him to expend all his energies without giving me any pleasure, so i quickly pulled my head out of the shower and got undressed. even though i was embarrassed by my women's underwear, i was a little disappointed when the dental floss thin strip of thong came out of my crack; i was actually enjoying it there. i had a little bit of trouble with the bra, as i found out that these things are even harder to take off of yourself than someone else, but eventually i was naked and ready to fuck. i got into the shower without making any announcement of it and stepped right up to greg, starting to rub my tits and pussy against him. he was so surprised as first that i think he almost cried out, but when i dropped to my knees and took his prick into my mouth, he seemed much more at ease. i had to rinse his dick off first, because i really didn't want to suck something that tasted like a bar of soap, but then i got down to business with a vengeance. i sucked him hungrily, grabbing the base of his cock and pistoning my head back and forth, fucking my face with his dick. there was nothing slow and gently about it, we were both raging sex maniacs and we wanted pleasure now. i was rough with his cock, sliding the tips of my teeth up and down it and nipping at the head, but he just grabbed me by the head and proceeded to force his dick in and out of my mouth, fucking my face even more forcefully than i had been doing to myself. i felt powerless, realizing that greg could easily overpower my body in it's petite, feminine state, and there was nothing i could do but let him pump his cock in and out of my throat at his pleasure. speaking of greg's pleasure, there was one way in which i could seize some sexual initiative, and i did. now that greg was furiously fucking my face, i had both hands free, and he was standing in front of my kneeling form with his legs slightly spread. i felt my way around the tub until i found the bar of soap sliding around forgotten by the drain, and after pausing to lather up my entire right hand as thoroughly as possible, i reached up between greg's legs and parted his ass cheeks. while rubbing and caressing his scrotum with my left hand, i slowly slipped the index finger of my right into his asshole, just up to the first knuckle. greg let out a grunt that sounded half of surprise, half of pleasure, and started to pump his cock down my throat even faster and more forcefully. i wriggled my finger back and forth and started to rotate it, just to get him used to the sensation. i knew from my recent experience with my own asshole that being filled there was quite an enjoyable feeling as long as you had time to get used to the pressure. come to think of it, greg was probably enjoying this even more than i had, because now that i was a woman, i no longer had a prostate. i wondered what anal penetration would feel like for a man, but i continued to stimulate him there as he fucked my throat. i inserted my finger further, curling it over to reach where i had learned in biology class the prostate was located, and i was rewarded with a frantic grunting from greg. i kept my finger there as he fucked my face even faster, his grunts and groans rising in volume. suddenly, greg went rigid. sensing his orgasm was imminent, i forced my finger the rest of the way up his ass, until my knuckles were pressing hard against his sphincters. greg pulled my head violently towards his crotch, shoving the full length of his ten incher down my throat. i hadn't yet been able to take more that about two thirds of it, and the whole thing shoved rudely down my esophagus nearly made me gag. i felt like a sword swallower in a carnival. then the cum started to erupt from his balls and i realized that if i came into contact with a whole lot more of that stuff, i would look like a carnival freak of an entirely different sort. i tried to pull back away from his cock, but his hands held me there as the sperm spurted down into my stomach. by the time he finished rocking back and forth, there was a warm spot at the pit of my belly, and my tits and hips were feeling warm and tingly again. i resolved to touch no more cum, ever again. my breasts were large enough already, and after they finished growing from this load, i didn't want them to grow any more. the though of being a woman was bad enough without being a woman with freakishly large breasts. i was still horny, though, and i had a craving for more cum that had been intensified by the load i had just ingested. summoning all the presence of mind i could while i was essentially drunk on cum, my tits and hips tingling and throbbing as they began to grow, i led greg out of the shower and dried us both off. leading him into his room, i pushed him onto the bed and held up the condom i had brought with me. greg didn't look too happy about that, so i emulated something a girl had once done to me, when i was still a man. i took the rubber in my mouth and positioned it across the inside of my pursed lips. leaning over to engulf greg's prick, i slowly unrolled the condom down his cock, using only my lips and tongue. greg seemed to mind the condom somewhat less when he experienced my manner of employing it. when i had his cock completely wrapped, i got up onto the bed and squatted over it. my pussy was crying out for a reaming, but i waited a minute, teasing myself and greg, with my hand holding his rapidly hardening dick upright, and my cunt suspended less than an inch from the tip. greg started to buck his hips back and forth, rubbing my hand on the base of his crotch and just barely brushing the tip of his dick against my clitoris at the apex of every movement. just the feel of that nearly made me cum, i was so desperately horny. the teasing sensation of the feather-light touches of his head at the focal point of my vagina nearly sent me over the edge. i restrained myself, however. i wanted to be well and completely fucked before i was done with him, especially because i wouldn't have what was normally my main satisfaction, the cum that i craved so badly. so, after letting him tease my clit with his cockhead for a few minutes, i positioned the head at the entrance to my dripping wet hole, and impaled myself upon his cock in one stroke. having my pussy filled at that particular moment was the single most satisfying sensation i could remember. i needed to be fucked, like i'd never needed anything before in my life, and this cock filling me so completely was the most pleasurable thing imaginable. for once, no part of my mind was dismayed by the thought of fucking this man, i just knew in my mind that this was what my body needed, with a biological urge that, though artificially induced, was so desperate that it overrode any objections my mind could have to this form of relief and made it my sole purpose to seek fulfillment from this cock. thinking that the sensations might be slightly muted for greg because of the condom he was wearing, i made a special effort to massage him with my pussy muscles. although i hadn't had them for long, they had been in good shape when i awoke as a girl, and had received almost constant practice and exercise since then. i clenched my cunt as hard as i could around his cock, hearing him grunt from the sudden tightness of my pussy. i bore down on his crotch, rolling my hips with his dick contained in my cunt, unwilling to relinquish any of this incredibly full feeling i was enjoying, even for the sake of stroking his cock in and out. instead, i just rolled my hips, gaining sensations from the way that caused friction between his cock and my pussy, though as wet as i was, i'm surprised there could be any friction at all. all the while i was grinding my clit as hard as possible down against his pubic bone. realizing that my body now weighed so little that i couldn't actually exert much pressure just by force of gravity alone, i grabbed greg's sides and pulled myself down on him that way. realizing my predicament, greg grabbed my asscheeks and grinding my clit down on him with all his force. desperately rolling my hips, i began to whimper, then to moan, and finally to scream as my orgasm raged through me. it seemed to last forever, as the sheer sensation of the orgasm ate up all the other sensations i had. bit by bit, i lost contact with the world, squeezing my eyes shut until it wasn't even black anymore, all i saw was white. eventually i realized i couldn't even feel greg fucking me, i couldn't even feel my body, all i could feel was this colossal orgasm, and i was floating in it with no reference points whatsoever. gradually, i became reacquainted with the real world, and realized i was too spent and exhausted to move a muscle. i was just lying there on top of greg, with his cock still stuck up my pussy, totally limp with my arms and legs lying askew. greg, realizing that i would be no more help to him, and knowing that fucking with the girl on top requires concentration, eased me off of him. rolling over slightly, he deposited on my side in the middle of his bed. standing up, he lifted me easily in his arms and carried me through the bathroom and towards my room. any suspicion i had that he was going to gently deposit me on my bed and return to his own room was proved wrong my the feeling of his prick, so fantastically erect that it was standing almost vertically against his stomach, pressing up against my back as he effortlessly carried me. he did deposit me gently on my bed, but face down. i could already feel the difference in the size of my tits from the load of cum i had swallowed in the shower, and all it did was make me horny. greg arranged my arms comfortably so that i could grasp my tits with what little strength i had left, and he spread my legs out straight across the bed. parting my asscheeks slightly, he reached down deeper between my legs to get some lubrication from my still dripping pussy. he brought this lubrication back up along the crack in my ass to my tight little asshole, and proceeded to rub it in, massaging and loosening my tail as he did so. when he had done this for a moment or two, he put both his hands back to holding my cheeks apart, and i felt a slight pressure against my ass bud. slowly, and gently, he entered my rear opening. although i had had my ass fucked last night by greg's roommate, ian, while greg was busily pumping my pussy, i was not prepared for greg's much bigger cock. apart from being at least two inches longer, greg's tool was much thicker and harder, and my asshole was still very tight. if i had had the strength to do so, i probably would have asked him to stop, but as it was, i could just lay there on my stomach and knead my tits weakly. actually, my exhaustion may very well have been to my advantage, causing my ass muscles to be more relaxed than they ever would have been otherwise. feeling no resistance, greg slowly stroked his cock all the way into my behind. as i lay there and felt it, i was constantly sure that i had reached the last of it, that any time now he would rub the base of his cock up against the outside of my asshole. but it must felt even larger than it had looked, and by the time the base of his cock was actually touching my poor little asscrack, i was more indecently filled than i had ever imagined possible. i thought that there couldn't possibly be any way he could fill me any fuller, but he grasped my (now noticeably wider) hipbones from behind and pushed into my ass, fighting to gain another fraction of an inch of insertion. he seemed reluctant to pull it out, he just wanted to stay there, completely enveloped in my ass, and so he didn't stroke in and out, but just clenched my ass to his cock like a vise and tried to thrust deeper. he never pulled out any, he just tried to go deeper, rocking back and forth ever so slightly. this rocking motion caused a little tiny feeling of friction between his cock and the internal walls of my asshole, as well as rubbing my clit against the sheets bunched up under my hairless mound. i rubbed my tits as forcefully as i could, which wasn't very, and laid there helpless to resist, just enjoying my assfuck. greg continued his attempt to get even further into my ass. i would have thought he had already penetrated me there as deeply as humanly possible, but he continued to redouble his efforts, the muscles on his arms standing out with the strain of pulling my ass back up onto his prick as hard as possible. his rocking continued, speeding up slowly, but the miniscule amount of movement he was causing allowed him to hold out a long time before cumming. i would estimate that he was straining to further explore my asshole for nearly forty five minutes, but i might not have been in a good stated to judge, being that i was so exhausted that i would not have been able to stay awake except for the fact that i was orgasming regularly, every five minutes or so. my clit was getting sore from rubbing against the sheets, and i was wondering how long he could keep this up, when greg suddenly let out a "humph!" and impaled be onto his cock by perhaps another centimeter, which i would a moment earlier have declared impossible. i could feel his cock spasming in my behind, and i could only hope that the condom held, or my tits would be growing even more tonight. greg held himself tightly into my ass for nearly thirty seconds, completely rigid and grunting, before his orgasm subsided. then he collapsed on top of me and laid there for a few minutes before gathering his strength and getting up to stagger drunkenly back towards his room. i was asleep before he reached my door. my dreams were exceedingly strange. i dreamt of being in the room with tiffany, but i was my old male self again. in the dream, though, i had never been otherwise. tiffany's tits were enormous, much larger than they were in real life (not that her real life tits could ever be considered small.) i wanted to fuck her, and suddenly we were naked. without apparently moving to a bed, we were fucking, and the longer we fucked, the smaller her tits got. after a while i noticed that i was growing tits and hips as we fucked, but i still had my dick. eventually, tiffany's tits and hips had shrunk until she was entirely a guy, except for her pussy, and i was outwardly a woman, with ridiculously exaggerated tits and ass, except for my dick. as we continued to fuck, my dick started to shrink, and her pussy became less concave, moving out to match my dick shrinking back. for one short second, we both had smooth, featureless crotches that we nonetheless continued to rub together, then tiffany began to form a dick and my own crotch dimpled in and began to resemble a pussy. finally, i was completely a woman, with huge breasts the size of garbage cans, and tiffany was completely a man, but her dick continued to grow, stretching me wider and wider as we fucked, stretching me all out of shape. i felt it continue up into my body, first one foot, then two feet, until i could feel it almost up to my collarbone, all inside of me. it hurt, but as it grew it pleasured me even more. finally, tiffany began to cum. i felt warm, salty sperm bubble up from the back of my throat. my own orgasm began, and that's when i woke up. once again, i woke expecting to find myself a man, but the squashed sensation of laying on my breasts and the well reamed feeling in my pussy and asshole reminded me that i was in fact a woman. i looked towards the window to find that it was dark. i looked at the clock. 12:42. i had slept almost ten hours, and now i was well rested, but i had nothing to do. i looked over to tiff's bed, to see her sleeping. i could make out the round globes of her gigantic tits under the thin sheet. it looked like she was sleeping topless again. my pussy started to wet itself. i got up and headed towards the bathroom looking to survey the damage i had done by swallowing that one load of cum. the two times before, i had ingested, either by swallowing or by having them shoot it in my pussy or ass, multiple loads, so i hoped that the growth would not be as severe as it was in those cases. my breasts certainly felt heavier, and my hips seemed to swing out a bit wider as i walked, but any changes in your body seem like a huge difference to you. i wanted to look at the mirror and find out how i looked to other people. all in all, i wasn't pleased but it could have been much worse. i had been at the point were i had very large tits but they weren't that far out of the ordinary. quite a few woman have dd cup breasts, although most are not as thin as i am. unfortunately, that means i was at the point where only a little bit more would put me over the top. looking at my new breasts, i thought i still might squeeze into the dd cup bra, especially because all of my bras were those little half cup things, but the custom made e cups i saw in the drawer would probably be more comfortable. the change was noticeable, but not overly pronounced, but the effect was remarkable. with dd size breasts, i looked extremely sexy, but was basically a normal girl (on the outside i mean; i'm currently ignoring the fact that i'm actually a man.) now, however, with only a small change in proportion, i looked as it my body had been purposely designed for sex. my huge tits levitated out from my chest, so spherical that i would almost have thought they looked fake if it weren't for the fact that they swayed and jiggled like real tits. my hips had also flared out by an inch or two on either side, making my waist look thinner. it suddenly occurred to me that my legs, armpits, and pussy might need to be shaved, but when i checked them, only my pussy showed any evidence of stubble. maybe whoever did this to me made my legs and armpits naturally hairless. all in all, i was sure i couldn't go outside the room now without every guy inside of a hundred yards staring at me as i walked. i was a walking incitement to riot. my only comfort was that the effect was largely subliminal. the guys who had seen me in class today would notice me even more tomorrow, but probably wouldn't notice the growth in my chest and hips. i just had to be sure to avoid cum at any cost. i put the condoms in the bathroom counter drawer, so i would be able to grab one as i went from my room to greg's and ian's. then, i decided to get some relief for my dripping pussy and ragingly hard nipples. i had intended to let tiffany sleep, but i now decided she probably wouldn't mind if i woke her up. i went over to her bed, looking at her gigantic breasts and realizing for the first time that mine were now the same size. that brought the new changes in my body home even more, making me realize that this huge breast size i saw before me was the size that was hanging buoyantly on my own chest. that astounded me, even though i already knew it intellectually, but now that i was quickly getting very horny, it didn't bother me so much. in fact, it didn't bother me at all. i just kept looking at the size of her tits through the sheet, and thinking "mine are like that!" my nipples crinkled even more. i wanted to get a good look at her breasts, so i slowly pulled the sheets down off of them, being careful not to wake her. i looked at her like that, laying there on her back with her head pillowed on her long blond hair and her breasts laying back on themselves so that they were really high on her chest and didn't fold over at the bottom at all, but they were still gigantic and stuck up quite far. it suddenly occurred to me that my breasts were prettier. ours were both the same size, but i had only had mine for about two days now, and at first they had been very small, so gravity hadn't had a chance to make them sag (and if i had my way, i would soon be a man again and it never would.) tiffany's breasts, though they were very spherical and rode very high on her chest, showed more evidence of gravity than mine. "not much, though," i thought to myself. "i'd almost think that they were fake, if i hadn't felt them. they feel to good, soft and squishy and firm at the same time, to be silicone breasts. i wondered how the rest of her would compare to the rest of me. on our faces, i had no opinion. hers was pretty, and i knew mine was too, but after only two days, i was actually starting to get used to it, and nobody can actually make good judgements about their own face. my body i could think objectively about, because it hadn't stayed the same long enough for me to get used to it. i pulled down the sheet over tiff's legs, wondering what she was wearing under it. nothing, as it turned out. i pulled the sheet all the way down and off of the bed, revealing her long, smooth legs, laying bent slightly sideways on the bed. as far as legs went, we were about even, but mine had the edge i think because they were so completely smooth. also, since i had never shaved them, they didn't have any razor scars. moving upwards, my hips and ass were a bit wider and rounder than hers, and my waist flared in slightly more, so i guess i won on that point. my stomach was flatter, in fact i was a bit thinner all over my body except for the tits. the tits i already spoke of. i liked mine better because they sagged less (not that anyone would have accused tiffany's of sagging) and also because of the nipples. through all the growth that my breasts had gone through, the nipples had stayed the same size as when i had had a cup boobs. now, i found it incredibly erotic to have these tiny dime sized nipples jutting out rock hard on top of these huge e cup breasts. the final comparison was in the cunt. on that, i won hands down. i hadn't really had any opinion on this point before, but since i had become a woman and felt the huge difference in sensation after i shaved my pussy, i had begun to find the lack of pubic hair extremely visually arousing as well. tiff didn't have much of a patch, just a little tuft of blond hair just above the top of her slit, but to my mind, any at all was too much. i decided that when i got turned back into a man, i would suggest to my next girlfriend that she shave off her pubes, not only for my enjoyment but for the increase in sensation that i now knew it would bring her. i started to think of greg's clean shaven cock, and my breathing got heavier. i wondered at the fact that, looking at it from an objective point of view, i was now prettier and made a better woman that tiffany, who was a knockout by anyone's standards. did that make me a knockout? all i knew is that if i was still a man and i saw a woman who looked like i did now, i would want to fuck her. speaking of wanting to fuck her, i was still getting really horny from staring at tiffany's naked, sleeping form. i went over to her and started to rub my hands over her tits. then i leaned down, and with both hands, i put our tits together and started to rub mine up against hers. tiffany started to roll her head back and forth and moan in her sleep. i got up onto the bed and put my knee between her thighs, rubbing my leg into her crotch. as i rubbed, i could feel the lubrication seeping out of her pussy. her eyes started to flutter, and she moaned "oh, chris!" she wasn't awake yet, so i started to kiss her neck, working my way up to her lips. i kissed her on the lips, forcing my tongue in between her lips. i felt her hot breath blowing on my face as i felt my first kiss as a woman. i stopped to catch my breath, and tiffany moaned "oh, christopher!" that brought me up short for a moment. how could she know my real name, when she'd never met me as a man? i decided that either she was having a dream like i'd been having earlier, or she was just dreaming about someone else and the name resemblance was a coincidence. i went back to kissing her neck. tiffany's eyes fluttered some more and then opened, and then closed again as she sank back with a smile on her face. i was trailing kisses down the middle of her belly, stopping to insert my tongue for a moment into her belly button, then continuing down over her little tuft of pubic hair and into her slit. her pussy was by this time soaking wet, so i didn't really have to linger at it for long, but i did anyway for my own enjoyment, and to tease tiff for a while. i licked up and down the creases on the inside of either thigh, not touching the pussy itself, just stimulating the skin around it. i moved down to the skin between the pussy and the asshole, almost touching the ass bud, and licked there for a while (i'm happy to report that tiff's ass seemed clean as a whistle.) then i began licking the top of her mound, to either side of the carefully shaved pubic hair. by this time i knew tiffany was aching to tell me to eat her out, but was restraining myself because she didn't want me to know how much i turned her on. i stopped licking around her cunt and made as if i was about to go for the main course, but at the last minute i stopped short. i just stayed there, not touching her cunt but blowing softly on it, for twenty seconds or so until she couldn't hold back any more, and she moaned softly, "eat my pussy! please! i need it!" now that i had been asked, i was happy to oblige. i went to the task at hand with a vengeance, licking up and down the slit and sucking the clitoris into my mouth. i inserted my tongue into her cunt hole and fucked her with it until it started to ache a bit, then took her clittie back between my lips and sucked it hard. she moaned, half in pleasure and half in pain. i started to flick her clit gently with my tongue while still keeping it in my mouth and sucking it, and tiff erupted like a volcano. she thrashed around on the bed like a wounded animal, gripping my head between her legs as if they were pincers, and i was just along for the ride. i didn't stop sucking her clit, though, so her orgasm lasted a long time. after about minutes, though, she was done and laying there limp on her bed. i wasn't done, however. i went over to her dresser drawer and pulled out the strap on dildo she had fucked me with the day before from it's hiding place under her sweaters. i belted it on and looked down to see a cock jutting from between my legs for the first time in two days. it was extremely weird to have to look between two enormous tits to see it, and it was longer than mine had been and looked even bigger because the rest of my body (except tits and ass) was smaller, but i felt fairly sure that my eight years of experience would carry over, and i'd be able to use it with some finesse. i was right. from the minute i stuck it into tiffany, she perked back up and was soon fucking wildly. i grabbed her ass and spread her cheeks as i drove the plastic cock into her pussy, and i shoved my tongue down her throat. i found that the friction of the base of the dildo against my clit gave me quite a bit of pleasure, and i tried to abandon myself to the feeling and fuck her as if i were a man. i actually tried to pretend for a while that i was a man again, but it was made impossible by the way our tits rubbed up against each other as we fucked. not that that sensation was at all bad. when i abandoned the idea of trying to pretend this was actually my real dick and fucked her like what i actually was (namely, a sex crazed bisexual cum hungry slut) i found that i actually liked the sensation. either of us had huge tits, but when you pressed them up together there was twice as much flesh between our chests. our breasts pushed us so far apart that it was almost hard to reach each other to kiss, and i loved the feel of our tits and nipples sliding against each other when they began to get sweaty and slippery. i was enjoying myself immensely when i suddenly felt hands spreading my ass cheeks. i looked behind me to see ian standing there, grinning. "have you got a condom?" i asked, wanting to avoid any further enlargements. "why are you so worried all of a sudden?" he retorted. for a minute i considered telling him the truth, but i decided that informing him that cum would cause my breasts to get even bigger might get me raped, so i just said "i just decided that the other way wasn't a good idea. go in the bathroom and get one out of the drawer." he started to sulk and i added, "i'll make it up to you later." he did as i asked, and i went back to reaming tiffany's pussy. she had offered no objection to ian joining in, in fact earlier she had implied that she would want it, so i figured she wouldn't mind. i was kneading her ass cheeks and pinioning the dildo into her cunt with all the force i could muster, so i had almost forgotten about ian when he returned, condom dutifully applied. i felt hands spreading my ass cheeks again, and didn't look around, knowing what was about to happen. ian put the head of his cock up against my asshole (i could feel that he had lubricated it with something, probably the ky jelly i had seen in the bathroom drawer) and pushed it in. it felt tight because i hadn't had any preliminary warm up to this anal penetration, but greg had stretched my ass all out of shape earlier in the day, so it wasn't painful. it began to feel good almost immediately, and though it was hard to maintain a consistent rhythm, with three people involved, i don't think any of us minded the times when we would fall out of sync. tiffany came first, and most often. i wouldn't be surprised if she had orgasmed five times in that session. i came next, and it was a really good one. i decided that i liked being in a sex sandwich between a guy and a girl as much as between two guys (and i started to wonder what it would be like between two girls.) i was thinking about that when my second orgasm hit, a moment later. this one was more leisurely and sedate than the first, but no less enjoyable. i was just winding down from that one when ian tensed up, grunted, and shot his load. i waited for a moment, but i could feel no tingle in my breasts. apparently, my plan had worked. we disentangled ourselves and lay on the bed for a moment, gathering our strength. it was then that i noticed greg standing in the corner, slowly massaging his dick. i didn't know how long he was there, but decided i didn't have many secrets from a guy who had been inside all three of my major orifices (except for the one big secret, but i didn't see any way he could find that out,) so i just shrugged to myself and got up, walking over to him. i applied a condom to his cock with the same technique i had used earlier, thinking to myself that if this went on, i would have to buy condoms by the gross. then i kneeled on the floor in front of him, sucking his condom encased cock for all i was worth. i didn't know where i had developed this appetite for sucking dick, but i assumed it had been a side effect of my chemically induced craving for cum. whatever the reason, i enjoyed doing it now, as i licked up the underside of greg's huge, smooth shaft and let the tip of my tongue dance on the mushroom shaped head. after teasing the tip of his cock, i suddenly enveloped it. after the face fucking i had received, i found it possible (though still by no means easy) to take his entire length down my throat. i still had to fight for it, shaking my head back and forth as if to say "no" when what i was really thinking was "yes!" finally, i had it all down my throat, and i felt him take a hold of my head again and begin to fuck his cock in and out of my mouth. realizing that he could now take his pleasure of my mouth at his own pace, i reached down to give myself some relief. i brushed my left hand across my breasts, lightly touching my nipples, which were again in pleasant pain from being so erect. my right hand went directly down into my soaking crotch. i slid it gently across my mound, feeling the slightest hint of stubble (must remember to shave) and parted my lips, inserting two fingers into my hole. i didn't need any sort of prelude or foreplay, i was already as wet and horny as it was possible to get. i pumped my index and middle fingers in and out of my hole, and my thumb found my clit and started to massage that. i found that it worked best if i didn't try to move my thumb. the constant movement caused by my shoving my first two fingers in and out of my opening caused enough movement in my thumb to do the job on my clit. my left hand was still massaging my breasts, one at a time. more accurately, part of one at a time, because they were now so enormous that i could never hope to fit one completely into anyone's hand, let alone my own dainty feminine ones. my tits felt warm and good, but i wanted to be filled in another place, so i slipped my left hand down into my pussy for some lubrication, and then reached around behind myself, parting my ass cheeks. my asshole had been much used since last time i had masturbated it, and it was somewhat larger than it had been. i now found that i could fit two fingers into it, not at all uncomfortably. i relaxed there on my knees, luxuriating in the feeling of being completely full, ass and pussy. i savored the feeling of my fingers pumping in and out of me, front and back, as greg fucked my face at top speed. finally, i began to cum. i stuck my fingers up my ass and into my pussy up to their knuckles and just rode out the orgasm like that, sucking greg's cock into my mouth harder as i squealed my pleasure. the sight of my playing with my pussy and asshole, quite understandably, had been quite a turn on for greg, and he began to buck his hips in that characteristically uncontrollable way and filled his condom with cum. i fell back from where i had planted his face in his crotch, and lay there on my ass for a moment, looking over to where ian and tiffany were. i needn't have worried about making introductions. ian was seated on the edge of tiffany's bed, and tiff was servicing him in much the way i had just been doing to greg. she was also playing with herself, like me, but instead of fingers up her ass she had the dildo that i had recently been fucking her pussy with. satisfied that they were taken care of, or at least were taking care of each other, i turned back to greg. greg pushed me over onto my back, and then he lowered himself onto the floor next to me. his cock was hardening again, but slowly, and i decided to give it a little hand. i reached out and took it in my hand, stroking it slowly back and forth. this action, at least, felt totally natural. i had done it so many times to myself, it was just weird to be doing it to someone else. greg, meanwhile, had reached up to play with my enormous breasts (what man wouldn't?) and was rolling the nipples around between his thumb and forefinger. this sensation made them even harder, and i started to moan louder and rub his dick faster. greg started to thrust his hips up against me, and soon he couldn't stop himself from mounting me and entering my pussy. i can't say this enough times: i loved having my pussy fucked. the sensation of being full was unbelievable; the ecstasy of fucking was still there, but with this added pressure. not to say that i didn't want to be a man again, but as long as i was a girl i wanted to do this as often as possible. i don't think greg minded either. he reared up between my spread legs and pounded into me with incredible force, while i was all the while encouraging him to fuck me even harder. i reached down between my outstretched legs to feel his dick going in and out of my opening with my hand, reassuring myself that these wonderful sensations i was feeling from my crotch were, in fact, real. greg continued to pump away at my pussy, his hands gripping my hips tightly for leverage. it occurred to me that there was a much better grip now than there had been when i woke up yesterday as a woman, and i actually gloried in the fact. if i was going to be a woman, even for only a short time, i was glorying in the fact that i was a huge titted, round assed whore of a woman, who was repeatedly fucking both of these two guys who i had yet to exchange more than a few sentences with. i thought back to how i would probably reacted in a similar situation when i was still a man, and realized that these two certainly didn't mind. all they really wanted was sex, and as that was all i was interested in from them, i felt we had a fair exchange. i abandoned myself again to the sheer sensation of greg's cock sliding in and out of my two day old pussy, feeling the shaved, hairless area above his cock slap up against the smooth mound above my clit. i really preferred greg's hairless cock to ian's hairy one. by now, greg was starting to speed up in his fucking me and his breathing was becoming irregular. i felt my own orgasm hit without warning, rushing through my body like fire through my veins, and i screamed my appreciation so loud that everyone up and down the hall must have heard it. i felt like i was seeping slowly away from myself as i dissolved into a puddle on the floor. greg tensed up and shot another load into his already full condom. he drove his dick all the way into my pussy and left it there for a bit, while he recuperated. i savored the full feeling all the more because i knew it wouldn't last much longer now. soon, he pulled out of me and got up, walking back to his room. ian, having recently reached his own orgasm, followed his roommate, leaving me and tiffany as two well pleased sluts, lying exhausted about our room. i awoke the next morning still on the floor, with dried pussy juice all over my thighs. i had awoken already with the decision not to go to class today, and as it turned out i didn't really even have the option, as it was already ten o'clock and tiff had already left for class. i got up in a leisurely manner, and headed for the shower. i stopped on the way to examine myself in the mirror. yes, my judgement last night had been correct, the condoms had stopped my tits from getting any bigger. i felt relieved, but also slightly disappointed. the man in me wanted to see tits that grew completely out of proportion with the rest of my body. i got into the tub and washed off my body, feeling the spray of the shower wash over my sensitive skin. i let it linger as long as possible on my huge mammaries, as the hot water was really the only thing that could make my nipples relax completely. they were otherwise always at least a little bit erect. i felt down between my legs and lathered up my mound, shaving it again so that it would be completely smooth. i checked my legs and armpits again, and concluded finally that they were now permanently hairless. i got out of the shower and toweled myself off. i went back into the room and began to get dressed. i picked out a blue pair of thong panties, again avoiding the pink, and one of the half cup bras to match. yes, the e cup did fit much more comfortably than the dd. i then pulled on a pair of jeans and a t shirt. i had to check to make sure that the jeans were the same size as the ones i had worn to class yesterday. they were so tight i could barely get them over my hips, even completely unzipped, and when i did i had a hell of a time zipping them up. i looked at myself in the mirror and realized that they fit me like a second skin. even my formerly loose t shirt was stretched tight over my tits, and my nipples were showing through with no possibility of mistake. i decided that, if i looked this indecent even in clothes, there was no point, and i may as well be comfortable. i lounged around in my underwear. my tits were actually more comfortable in the bra, because of the extra support, and i looked at myself in the mirror wearing just bra and no panties, and decided that i looked stupid (i wouldn't admit even to myself that i actually was enjoying the feeling of the g string wedging itself up into my ass, and rubbing back and forth against my ass nub as i shifted and moved around.) i watched tv most of the day, but as daytime tv wasn't that interesting (even if i was now a girl, i still couldn't get into soap operas and talk shows) mostly what i did was masturbate. spending a whole day with my hands in my panties kept me fairly satiated, and when a knock came on the door connecting our room to the guy's at about three o'clock, i said "come in!" without any immediate intention of raping whoever it was. it was ian, and to my surprise, he was fully clothed. i lay there unselfconsciously, knowing that he had already seen me even less covered up than this. it turns out that the boys wanted to invite me to go with them to a party. i didn't really want to get into the habit of going out on dates with men, but i figured that since it was both of them, it couldn't really be called a date. "jeans and a t shirt ok?" i asked, not really expecting a dress code. "actually," he replied, "it's a bit more upscale than that." he left before i had a chance to respond, so i didn't get the chance to beg off. as i thought about it, though, i decided that wearing a dress wouldn't be so bad. it wasn't like i'd look like a man in drag. i had the kind of body currently that was supposed to wear dresses. also, i was kind of tired of staring at the television, and i wanted to get out and do something. we all left for the party at about ten o'clock. i still hadn't heard seen or heard from tiffany, but i picked out a black dress (the longest one i had, and still the hem was closer to my hips than my knees) and some very low heels, and i was carrying a purse. i still wasn't bothering with cosmetics, but i wanted to carry a few condoms with me, just in case. when we got to the party, at a fraternity house, i was surprised to see that as yet i was the only girl there. the frat boys were standing around looking kind of dejected, so i assumed that this wasn't the plan. they were all doing a good job of drowning their sorrows in beer, however. being the only girl there, and possessing a figure that could stop traffic, i had an endless supply of drinks being handed to me, and i soon became quite drunk. all these faces i didn't know were whirling around me, and i was wondering why they all seemed to be trying to flirt with me. i was a man, wasn't i? after an interminable time, i found myself upstairs in someone's private bedroom with ian. none of the other girls invited had shown up, or at least they hadn't stayed that long, and all the guys were doing quite a job of drinking themselves into a stupor. ian and i had slipped away upstairs for a little quickie, after i had felt inside my purse to make sure i had a condom. i was bent over the bed, my dress hiked up and my thong panties pushed to one side, and ian was behind me, rubbing his dick and applying the condom. when he pushed into my pussy from behind, it felt so different, because i was drunk and so much more relaxed than before. i just rode along the fuck in a blissful, erotic floating state, until i noticed something. i had been letting ian fuck me doggy style for a while, and suddenly it felt different. it felt like the condom was bunched up around the base of his cock. "pull out and make sure the condom's alright," i said i felt him do so, and then he said "shit. damn thing broke." what followed was too important a decision to be made in such a drunken state. i had already had a little bit of his pre-cum in me, and that accelerated my need for more. apart from that, i was more than a little drunk, and feeling the amiable apathy that strong drink brings with it, so before i knew it, ian had put his cock back into my pussy and was fucking me again, and i hadn't raised even a token protest. the first thing i realized was that it actually felt much better to be fucked by a bare cock than one encased in latex. i felt bare skin against my vaginal walls again, and i loved the feeling. i had gotten used to the feeling of being fucked, it seemed almost normal to me now, and i was enjoying the hell out of this particular fuck. ian reached around the front of me and pulled my dress up over my head, leaving me in just my bra and underwear, his dick still pushing the thong to one side and pumping in and out of my slit. he then reached down to my pussy and began to rub my clit as his dick stroked in and out of my hole. as usual, this sensation drove me over the edge, and as i tensed around him, gripping his cock with my inner walls, he reached his own orgasm and shot his cum up into me. the tingling in my tits returned with a vengeance, stronger now that i hadn't felt it in days, and in my drunken state i actually found it quite pleasant. i still knew that more cum would increase the sensation, and all i really wanted right then was to feel more of the wonderful warm, throbbing feeling in my hips and tits, so i quickly turned around and began to lap all my pussy juice off of ian's dick. i licked the length of it and took it into my mouth all the way in the first stroke, continuing to massage it with my tongue and pump it in and out of my face, but keeping it contained in my mouth and sucking it as hard as i could. i made no attempt to vary the sensation, i just stuck with what i knew worked fastest. i now had no intention of just making him hard with my mouth so he could fuck me again, i just wanted his cum inside me as fast as i could get it. when he came, in record time, i swallowed it without stopping and didn't pause, just continued sucking him to another orgasm. when i heard the door open i didn't even look up. i just spread my legs so that greg could pull off my panties, leaving me clothed only in my half cup bra (which was doing nothing, as i was on my hands and knees and my tits were hanging down out of the cups.) he then slithered up under me and slid his dick into my pussy. i was glad, it was just one more source of the cum that i needed so badly. i went on like that, sucking ian's cock while greg screwed me, and ingesting every drop of cum i could possibly get, when i noticed something. i was being fucked in the ass as well. i tried to look behind me to see who it was, but ian was nearing orgasm again and he just grabbed my face and stroked it up and down his cock. i relaxed to the thought. after all it wouldn't be the first time this week i had fucked some guy i didn't even know, and i craved more cum. i was addicted to it, i needed it now more than i had before, and the craving before had been almost unbearable. i floated off into a haze of sex. each time someone would shoot a load of cum into me, someone else would immediately take their place in one of my holes. i wasn't even doing anything anymore, i was just kneeling there on my hands and knees on the bed, as these guys fucked my face, pussy, and asshole. i was just a receptacle for their cum, and that was fine with me. i needed all they could give, and more. i serviced them all, and they began coming back for seconds. the cum filled up my openings, and began dripping out, but i knew that as long as it was touching my skin it would soothe my need for it, so i just cried out for more. the tingling in my breasts and hips was now enough that it was getting me off on it's own. as long as they kept cumming on or in me, the tingling kept up, so i was stuck in this constant orgasm that lasted hours. as you may imagine, it's hard to be to upset about anything while you're constantly cumming, so i didn't even raise a fuss when some bright boy got the idea that they didn't have to keep fucking my cum drenched holes (by now we were far past 'sloppy seconds.' i had serviced at least twenty five guys, and some of them were on thirds or fourths) but instead they could just jack off onto me. as the guy who had been fucking my pussy got out from under me, i realized that i was still on all fours, but my breasts were resting quite firmly on the bed. looking down at them, i could actually see them growing! very slowly, to be sure, but any visible growth was way too much with regards to my already overlarge breasts. as i said before, though, it's hard to mind anything while you're having an uncontrollable, three hour long orgasm, and the cum they were spurting onto me from their drunken circle jerk kept my hips and tits throbbing enough to keep the orgasm up, so i just stayed there. after a little while, i turned over onto my back, so that i could reach down and massage my cunt and finger my asshole while they jacked off on me. this just increased the speed with which they came, and the volume of cum that was splattering down on me, which once again increased the tingling. i was in ecstasy. i have no idea how long it lasted, all i know is that i woke up the next morning back in my room. greg and ian must have brought me back, unconscious. there was no way this morning that i could wake up still thinking i was a man. the immense weight on my chest dispelled that notion before i could even formulate it. i sat up slowly, feeling my ponderous breasts hanging down almost to my lap. looking down, i couldn't even gage their size. i decided to go the bathroom for a closer look. i staggered all the way there. it wasn't a hangover (actually, i felt pretty good,) it was just that my tits hurt a little from the weight whenever i moved and the unbelievable weight of my breasts threatened to overbalance me and send me toppling over. i reached the bathroom, took a deep breath, and looked at myself in the mirror. i started from the bottom, allowing my gaze to travel upwards. my hairless pussy was still naked, apparently whoever had tucked me into bed hadn't bothered to dress me. my hips were supernaturally wide, and as i turned to the side i saw that my ass stuck out in a full half circle. my gaze slid up again, past my impossibly thin waist (but not much past it) to rest on my tits. standing sideways like this, they stuck out more than a foot. as i turned to face the mirror head on, i saw that they were larger than watermelons. i stood there transfixed by the new size of my breasts. i had never imagined such an exaggerated set of proportions on a female body. i was appalled, but at the same time it made me impossibly horny. here was, in truth, too much of a good thing, but my animal nature couldn't help reacting to that good thing. my little hairless pussy was soaking wet, and my nipples (grown somewhat now to quarter size, which still looked ridiculously, arousingly small and pointy on these mammoth mammaries) were already rock hard. i had to masturbate, but first i had to try something. i went out to my room (still no tiffany) and rummaged through my underwear drawer, coming out with the size h custom made bra that was the largest i had been provided with. strapping it on and pulling it up my torso, i found that even it was entirely too small. my over-generous tits flowed out over the half cups, cascading down in front of them and looking generally ridiculous. i could never go outside with tits this size, certainly not without a bra. what could i do?

part 3

my body answered that question almost before i could formulate it. i could masturbate. in fact, i had to masturbate. as the voice had said to me, the more sex i had, the hornier i became. after last night, i knew that i would now be on a very short fuse, and that short fuse had been burned away by my male mind seeing my preposterous female proportions in the mirror. i must clarify something here, just so a reader (if this document ever finds one) won't think badly of me. i'm not one of those men who think that bigger is better, without a limit. if i had met a girl as a man with breasts the size that mine were, most of my mind would have been disgusted. breasts of this size almost qualify as a deformity. however, my more animal side can't help but react to large breasts, and unlike my aesthetic sense, my animal side doesn't have much in the way of limits. check this out with other guys; if they're truthful, they'll tell you it's true. big breasts bypass your higher brain functions and make you horny, the bigger the hornier. with the changes that had been forced upon me, i was constantly pretty horny anyway. i had been a woman for about four days, and my nipples had been hard for the entire time. apart from that, each time i came it made me even hornier. as i unclasped my too small h cup bra, i realized that i didn't feel as hopeless as i had when i first saw my breasts. it was hard to be simultaneously horny and depressed. i lay back, completely naked, onto my bed. i really wished that tiffany was here. i would have to explain my breast growth (or shrug and pretend i had no explanation, as i did last time,) but i much preferred sex with a partner to masturbating alone. i wasn't about to proposition one of the guys; my craving for cum had grown with my tits, and i wasn't too sure that i'd be able to make them put condoms on. even now, without one of them in front of me, just thinking about their creamy cum almost made me go next door and suck them off. thinking about it, but being very careful not to let myself get up off the bed, i let my right hand wander down from my mouth along my neck. when i got to my breasts, i was shocked again at the size of them. i ran my hands over my tits, marveling at how much tit i had to run them over. i had heard that women's breasts were less sensitive the larger they got, but that was not the case with mine. when i had those little a cup things, i could barely feel them, but with these gargantuan tits i could feel every breath of wind on the little, fine hairs that covered them. finally, i reached my nipples. they were so erect that they were sticking out like little points, the little cone shape extending out to the edge of the areola and jutting out perhaps an inch into the air. as the nipples were only about as big around as a quarter (erect, i mean; i had never seen them not aroused,) this meant that they stuck out about as far as they were across. needless to say, in the state i was in, touching them was an amazing experience. i pinched them gently and rolled them back and forth between my fingers, loving the feeling that sent shooting up into my body and straight down to my pussy. i felt like i could cum from just playing with my nipples. i wanted something a bit faster, however. leaving my left hand to continue to stroke my newly enlarged breasts, i trailed the right down along my belly. i felt the stomach that was still, impossibly, smooth and small in spite of the ridiculous growth in my breasts and hips, and trailed my hand down further. when i reached the area just below the subtle incurving of my belly, the place where my blond pubic hair had been until i shaved it off, i started to get even wetter. i loved the feeling of slickness there. i dipped my fingers quickly down into my slit, but brought them back up to my mound quickly. with lubrication from my pussy juice, i could feel the perfect smoothness of my cunt. it was still perfectly smooth from the shaving i did yesterday morning. i concluded that my hair grew very slowly. i didn't really care, though. i just was thankful because i loved the feeling of all that smooth skin above my slit, without a hair in sight. i hadn't even touched the slit yet, i was just rubbing my fingers over the top of my slippery mound. i raised up my head and propped it up on pillows so i could look down at my cunt as i played with it. my pussy looked almost like a little girl's. sitting there, with my legs parted only a little, there was not even a suggestion of stubble under the skin, only the nice little mound that slowly curves from one soft mound into two lips separated by a slit. i rubbed slowly across the mound and extended one finger to the top of the incurving line, just brushing my clit. it was tender! after last night, i wasn't surprised, but i could tell that if i was at all forceful with it, it would be very painful. i proceeded to brush it gently, sometimes not even touching the clit, just brushing around the little hood that enclosed it. even that was enough to give me immense pleasure. it wasn't that my clit was painful to touch, it was just that in it's slightly raw state, it was more sensitive both to pain and to pleasure. so pleasure it i did! i was grasping and pulling on my tits with my left hand while i rubbed my clit with my right. it was amazing! even after all the sex i had had as a woman, nothing had prepared me for this. my dick had never been anywhere near this sensitive. in fact, i wouldn't have been able to conceive as a man of anything being this sensitive. the pleasure i got, just from fingering my clit, wiped out any worries i had about who had done this to me, of how large my tits had become, or anything else. those things would return, but for now i was totally lost to my ecstasy. my wet pussy was crying out to be penetrated, so i wrenched my finger away from my clit and pushed it up into myself. it also felt definitely sore, but because of this soreness, i was so much more aware of the feeling of my finger sliding into me. where before i would have crammed two or even three fingers into my cunt (after last night, i was certainly stretched enough,) i now was completely satisfied to have one there. i moved it in and out for a second, then returned it to my clit. suddenly, i had an idea. i got my little vibrator from where i had hidden it in my dresser (under that pink dd cup bra that i would never wear now,) and grabbed tiffany's dildo from where it lay, forgotten, next to her bed. laying back down on my bed, i inserted the vibrator into my pussy. it filled my only partially, but it still felt extremely good. i didn't even turn it on, i just pushed it in and out of me for a few moments, until it was well lubricated, and then pulled it out. spreading my legs nice and wide, i felt under myself and pulled my asscheeks apart, then slowly inserted the vibrator. my ass was just as sore as my pussy, so the vibrator was slightly painful when i pushed it in for the first time, but i really wanted to be penetrated back there so i just clenched my teeth and kept pushing it slowly, but relentlessly, up my tail. finally, it was completely in. i turned it on, and immediately the pain turned to pleasure. i started to pump it in and out, gently because my asshole was still very sensitive. my pussy momentarily forgotten, i concentrated all my energies on the sensations i was giving myself by fucking my ass with a vibrator. it was amazing. i felt full, that's the best way i can explain it, so sensuously, ecstatically full, and the sensation was coming not from my cunt but from my asshole. after only about a minute of slowly pushing the vibrator in and out of my anal entrance, i came. after the orgasm subsided, and with the vibrator still buzzing in my ass, i began to work on my pussy. i took tiff's dildo and ran the tip of it slowly up and down my slit, teasing like i had done so many times to other girls with my real dick, when i still was a man. the flowing pussy juice lubricated the head of the dildo, and i felt myself gasp as it grazed up against my clitoris. i positioned the head of the plastic cock at the opening of my vagina, and slowly pushed it up inside. now i was filled, front and back, like i loved to be. i used my right hand to pump the dildo slowly in and out of myself, and my left hand to stimulate my clit. now the feeling was truly unbeatable. i had dildos in both my cunt and ass, filling me completely, and i was simultaneously playing with my clit. i knew i couldn't last long before i came. i was right. after only a few minutes of stimulating myself this way, i began to orgasm. unlike the other times i had masturbated, though, i didn't stop playing with myself. it felt too good, and so i decided to play with my pussy up until the moment when i was exhausted from the orgasm and had to stop. i discovered something about women about then. whenever i had cum as a man, there had been a time just after my orgasm when i was too tired to move. as a woman, i kept waiting for that time, but it never happened. my orgasm didn't end, either. it just came in and out of focus, alternately bowling me over with sensation and receding to a pleasant glow between my legs. i knew that girls could maintain orgasms much longer than guys, but this seemed insane. i could keep having this feeling as long as i kept fingering myself. i wondered why women ever stopped! i don't know how long i pleasured myself. it's hard to gage time while you're completely in ecstasy, but i would bet that my orgasm lasted about twenty five to thirty minutes before i collapsed from exhaustion. the next thing i knew, i was being shaken gently awake. i opened my eyes to see tiffany staring back at me. once i was awake, she stopped staring at my eyes and concentrated her full attention on my tits. "what the hell happened here?" she asked. "how much cum did you get?" "i have no idea," i replied. "dammit, girl, it looks like you were the guest of honor at a gang bang!" "actually, that's kind of what happened." i went on to explain the night before, and how horny it had made me, and tiff nodded understandingly, took me in her arms, and started kissing my neck and breasts. i lay back as she undressed herself with expert fingers while her mouth remained glued to my nipples. then, after becoming completely naked, she trailed her head down along my stomach to my hairless pussy. her mouth enveloped my clit and she flicked it with her tongue. she licked me up and down either side of my slit, where the outer lips met the leg. she fucked me with her tongue. she did all the things to me that she knew would make me cum. as i was approaching orgasm, i suddenly remembered something. i had never told tiffany that it was sperm that made me grow. as far as she knew, my enlarging tits had no reason at all. she certainly hadn't known me long enough to observe that my tits only grew when i came into contact with cum. suddenly, i remembered the time when she had called me christopher while she was half asleep. i thought it had been a coincidence, but it was because she knew it was my real name. also, i now knew why her voice was so familiar. it was the voice that i had heard whispering in my ear while i was strapped to the bed, having just been changed into a woman. i was very careful not to betray my sudden revelation. she licked my cunt to orgasm, and i raised her face up to my own, kissing her mouth and reaching around to feel her ass. i kneaded and massaged her ass cheeks as i pushed her back onto the bed, my own wide hips (wider than hers!) between my legs and my pussy rubbing up against hers, humping her as if i had a cock. all the time, though, i was thinking of how i could force her to change me back into a man. i rubbed my pussy against hers, bringing us both to an orgasm after an enjoyable eternity of rubbing our very female bodies together, and all the time i was bent on revenge. tiffany had gone out to order custom made bras for me, and had returned an hour later with a story that the lingerie shop she had gone to had "happened" to have some extremely large sizes on hand. i now had bras ranging in size from an i cup (keep in mind these are unofficial sizes, they were printed on the bras but anything this big had to be custom made) up to an m cup. that one was truly amazing. i thought to myself that i wouldn't need it, but i then reflected on my now overpowering desire for cum, and wasn't so sure. regardless, i still couldn't go outside without attracting too much attention, so i had no choice but to stay in. at least those bras made it easier to move around, and at least they were now so large that half cup bras hadn't been an option. when i first tried it on, the i cup bra fit well, if a bit snugly, but that didn't last very long. as i was laying on my bed, thoroughly bored and more than a little horny, there was a knock on the door that separated our room from the guys'. it opened without waiting for permission, and i saw greg standing there in his boxer shorts. "i wanted to apologize for last night..." he started. i knew that wasn't what he wanted, and i was quite mad at him for causing me to be gang banged, but all that evaporated as soon as i saw the bulge in the front of his boxers. immediately, i was across the room, frantic to get some cum. i tried to resist the craving, but it was now just too strong. i tried to force myself to make him use a condom, so that i could get some satisfaction from his dick and still avoid any more breast growth, but i was unable to do even that. the moment i saw him, my gaze was riveted to his crotch. now, what i craved wasn't even sex, that was secondary. what i needed was cum. if someone had offered it to me in liter sized bottles, i wouldn't even have paused to say "thank you." the craving was now that strong. i dropped to my knees in front of him and pulled his boxers down to his ankles in one smooth movement. i knew what he thought of me; in his mind i was just a slut, not so much a person as a convenient piece of ass. that was obvious from the way he had let me be gang banged last night. however, he wanted to stay on good enough terms to keep fucking me, and so he tried to apologize. instead of letting him, i had reinforced my slut status. but i really had no choice, the craving was completely in control. i took his instantly hard cock into my mouth. i marveled once again, as i had every time, at how good it felt that he was shaved as smooth as me. i had never heard of guys doing that when i was one, but i was glad that one of the guys i had fucked as a woman did it. i took his dick deeper and deeper into my throat, until his dick was pushing down my throat. my gag reflex was, however, overridden by my insatiable desire for cum, so i just kept inserting him further into my face. finally, my lips were wrapped around the base of his cock, and still i could fell no trace of hair or stubble. greg was so fastidious about shaving his cock that it was as smooth as my pussy, it felt like there was no hair to grow there. i loved the feeling of his slick shaft sliding in and out of my face. i pulled my head back until only the tip of his cock was still between my lips, and grasped the base with my right hand. i pumped the base with my hand while i orally stimulated the head. in fact, his dick was large enough that i could pump the base my hand and still pump a good length of the shaft in and out of my mouth, so i soon found myself doing that. feeling his hairless cock in both my hand and my mouth was extremely satisfying, but i still had my own needs, so i reached down between my parted, kneeling legs with my other hand and began to finger my own clean shaven cunt. it was already dripping on the floor, i was so horny. sucking greg's cock was an enjoyable experience, but at the moment, it was only a means to an end. all i really needed right now was cum, so i took what i felt to be the swiftest form of action. i removed his dick from my mouth, making sure it was well lubricated with saliva and pre-cum, and leaned back. i took my left hand from my cunt only long enough to unclasp my bra, letting it fall uncaringly to the floor, and then returned the hand to it's place at my pussy, making sure greg could see what i was doing. with my right hand, i continued to jack him off. i rubbed my hand back and forth like i had loved to along my own cock, as fast as possible, somewhat roughly, and concentrating on the head. i knew that this would be the fastest way to make him cum. predictably, i was right. greg's eyes were looking past his cock straight down to where i was fingering myself. his eyes were glued to my crotch as i slid two fingers very quickly in and out of my hole. i could see that it was as much of a turn on for him as it had been for me when i was a man and one of my girlfriends would masturbate in front of me. my other hand was moving back and forth on his cock so fast it was only a blur. after only a minute or so of this treatment, greg's eyes forced themselves shut and he fell back against the wall, groaning. his entire body tensed up, but i continued to jerk him off as fast as before. as i felt his spasms start, i aimed his cock at the place i needed the sperm most, and he shot his load all over my humongous tits. it came out in three spurts, and each was bigger than the last. after the third, a good portion of my breasts was covered with greg's creamy, white cum. i could feel them starting to tingle, but i was powerless to stop. i didn't even stop jacking greg's dick, i just continued to stroke it while it limpened and then quickly began to harden again. inside of ten minutes after the first, greg deposited a second load of cum onto my tits. after his second orgasm, greg pulled himself out of my grasp and staggered, weakly, over to my bed. he collapsed there on his back, as if he was unable to stand any longer. i followed him to the bed and started to suck his cock. i sucked as hard as i could, but i still could not produce an erection. i was frantic! i needed more cum! i pulled my mouth off of his dick and crawled up over his body. i spread my legs over him and proceeded to rub my soaking wet pussy against his limp dick, grinding my pubic bone into his. my hands were resting on the bed to either side of him, and my arms were still fully extended, but my huge tits still rested heavily on his chest and stomach. i rubbed them back and forth over him, rubbing his own cum off of my breasts and into his skin. i didn't mind losing it; it had already done it's job. i could feel my tits tingling like they were falling asleep, and i imagined i could almost feel them growing. the combination of my crotch grinding against his and my slippery tits sliding over his chest got greg's cock hard again, and as it began to stiffen it slipped immediately into my gaping, wet pussy. just a half hour ago i had been remarking again on how sore i was there from last night, but i was completely unaware of any discomfort now. i did still feel stretched, though. even greg's huge cock wasn't filling me completely. i wanted his cum, though, so i clenched down with my pussy muscles to give him the maximum sensation possible, and continued to grind against him like i had been. greg was exhausted, lying there like a wet rag, so i had to do all the work of fucking him. i rolled my hips back and forth, and side to side, trying to coax the cum from his balls. my slippery breasts were still rubbing against his chest, much more wildly now as i thrashed around on top of him, desperate for his sperm. it took almost ten minutes (an eternity considering the effort i was putting forth) until he shot another load up into my pussy. i immediately jumped off of his cock and started to suck it again. i lapped up the few remaining drops of cum as they squeezed out of the tip of his dick and continued to blow him as his erection softened. i still needed cum, but i was not sure if i would be able to force greg's overused cock into another erection. i concentrated all my efforts on it for almost ten minutes, becoming more frantic as time went by, but he stayed limp. finally, i had an inspiration. continuing to suck him off, i slipped one hand back down to my cunt. i finger fucked myself furiously for a few seconds, trying to get all of the juice from my soaking wet pussy onto my finger. then, i brought the finger back up to greg's crotch. i traced a hairless line around from the base of his cock, up against his balls, and down between his incurving cheeks to his asshole. i slipped the finger gently past his sphincters, realizing that his ass was as tight as mine had been a few short days ago. the difference was much more apparent now. i pushed my finger into his ass a little bit past the first knuckle, then curved it slightly up towards his dick and proceeded to rub his prostate. the effect was immediate. greg's dick stiffened at once, and almost as immediately i was up and on top of it. i knew that i would have to keep him horny enough that he didn't lose his erection, which could happen even while i was fucking him full speed, as exhausted as he was, so i squatted down over his cock and inserted it into my ass instead of my pussy. keeping my back straight, with my amazing breasts standing out from my chest, i made sure he could see that i was fingering my cunt as his cock pumped in and out of my asshole. i could tell he was enjoying himself in spite of his exhaustion, but i also figured this would be the last load i would get out of him. i rode him for all i was worth, pressing my asshole down onto his cock with all my strength. i clenched at his cock with my muscles, and pumped my hand in and out of my pussy, inserting all four fingers into myself. he watched with interest, but despite his exhaustion, it didn't take very long before he closed his eyes and shot his fourth load up into my asshole. i stayed there, no longer bouncing up and down in his lap but still fingering my pussy (because it felt good) and keeping his cock planted firmly all the way up my asshole (so that i would be sure not to waste any of his sperm.) after i was sure i would get no more from him, i left him there unconscious on my bed, and went into his room to see if ian was there. ian was lying on his back on his bed, the sheet thrown back. i could see that he was naked, he had probably been the one to bring me back to my room, in the dark area of my memory that lay between the last i could remember of the gang bang last night and the first thing i could remember about waking up this morning. he had probably been taking a few liberties with my near-unconscious form, and staggered, naked, back into his own room to fall asleep. all of which made no difference. i didn't care, when i saw his morning hardon poking up from the middle of his pubic hair. ian's dick wasn't as big as greg's, he had pubic hair (which i didn't really like,) and he wasn't as good in bed. none of this mattered to me either, because at the moment, all i needed was cum. i went over to ian, leaning down to plant my mouth on his dick. i wrapped my lips around his shaft, considering to myself that i actually knew from experience how good of a way to wake up this was. i took his cock completely into my mouth easily, especially after greg's monster. i rubbed my tongue and lips up and down the shaft, again going as fast as possible to get as much sperm as i could from him in the time i had before he was too tired. ian woke up with a grin on his face, which was understandable. consider this: he was hung over, but he had gang banged a hot slut the night before, and she was waking him up with a morning blowjob. now that's the breakfast of champions. needless to say, it didn't take too long before ian shot his first wad in my mouth, and i savored the taste while i continued to suck him. it bothered me for a moment that i was actually enjoying the taste of cum, but i chalked it up to the craving that had been artificially induced in me. in any case, it was hard to worry about anything while you were that horny. i just shrugged, and continued to suck his cock to orgasm again, fingering myself while i did. this time i jacked him off at the last minute so his cum would shoot on my tits, because that had made them tingle extremely pleasurably when greg did it. this went on much the same way it had with greg, with ian fucking me until he passed out. i then went back into my room, to find greg still passed out on my bed. i roused him to a sluggish semi-conscious state, managed to maneuver him back into his own room, and got one more load of cum shot onto my tits, before he passed out for good. i went back to my room and lay down in my bed, masturbating with my vibrator and tiffany's dildo until i myself passed out. i settled into a steady routine for the next few days. luckily, it was the weekend, because in the whole first week of classes i had only gone to one. i at least got through saturday and sunday without skipping anything, if only because there was nothing to skip. i just laid around my room (laying was easier, because then i didn't have to support my tits, which after the session the morning after the gang bang, had grown another size, to an estimated j cup,) and masturbated, fucking tiffany when she was around and when the boys were around, getting all the cum i could squeeze out of them. i couldn't help myself. i knew the effect it was having on my body, and though it made me horny i detested it, but it was as if i was some sort of sperm addict. i would assure myself that i would retain my self control, but as soon as one of them came into the room i was on my knees, with my gigantic tits hanging out, sucking for all i was worth. by sunday, when my k cup bra fit, i had decided that the next time i could, i had to follow tiffany out of the dorm. i knew she didn't have any classes, because i had looked in her backpack while she was in the shower and it was filled with blank notebooks, but i didn't know where she went when she left the dorm, or where she had done this to me. she left a couple of times over the weekend, and was gone most of the day monday and tuesday, but i didn't dare go out on monday with tits that were by now an l cup, apart from the fact that i knew that as soon as i reached the courtyard, i would be naked in the middle of it trying to fuck or suck any guy i saw. by tuesday night, i was starting to despair. my tits were now barely fitting into the m size bra, which was the largest i had. i weighed about 150 pounds, and about 50 of it was tits and ass. just for the hell of it, i had found a tape measure and taken my measurements: 62-22-41. how did that compare to the 6'2" guy i used to be? i was starting to have trouble getting up and moving around. i knew that my time was limited, and so i was glad when tiffany got ready to leave at about eleven at night. this late, on a tuesday night, the campus should be fairly deserted, and i could move around without too much fear. tiffany left by the door, and i had to hurriedly get dressed and follow her. the only problem was, i hadn't worn anything but a bra (by now, necessary except when i was actually letting greg or ian cum on my tits) since friday. the first thing i did was insert tiffany's dildo into my cunt, and my vibrator into my asshole, and turn it on. i knew that if i were to have any chance of returning to my former self, i could not be sidetracked if i happened to see some guy and crave his cum. this method had worked before, and i was praying that it would work now. it took me a minute to find something that would actually fit over my tits, and a minute more to mind some pants that i could pull up past my hips and ass. by that time, i was sure tiffany would be in the elevator and i would lose her. my heart sank. as a last resort, i decided to try climbing down the tree outside our window. it was much harder than i thought. my female arms had nowhere near the strength in them that my male arms had had, and apart from that my breasts, even strapped securely into the bra, kept getting in the way. finally, i reached the bottom of the tree and saw tiffany, walking off into the shadows. i followed her. she walked a little ways off campus, ducking into a back alley and finally entering a building through a sliding garage type door. i went around to the side of the building and climbed through a window that had been left open a crack, my heart beating up into my throat, because i was sure someone was going to hear me. i crept from the room in which i found myself out towards the light and speech i could hear from further within the building. i arrived in a large room that appeared to have been jury rigged as some sort of laboratory. there was a lot of equipment i didn't understand, but only a very few dim lights, which allowed me to hide back in the shadows. tiffany was in the middle of the room, standing in front of a table, facing and speaking to a group of women (thank god it wasn't men, i don't think i could have controlled the craving.) "...so as i have explained," she said, "this chemical forces a change in the genetic makeup of an individual, substituting an x chromosome for the normal y one, and changing other genetic material that we choose. we can, for example, program for a particular height, or appearance, or hair color. also in this syringe," at which point she held up a syringe, "is a chemical we have formulated to accelerate cell decay and reproduction, so that that individual's body is almost completely replaced with new cells, bearing the new genetic code. we have tested this on a human male subject, who had been living as a woman for slightly more than a week now. in this next vial, we have a substance that causes what in some ways is an even more interesting. it causes a reaction which is to be set off by the release of chemicals within the body, or the physical contact of certain substances from outside the body. in our subjects case, he... or she i guess i must now say, had been chemically programmed to react to human male ejaculate. when uh, she comes into contact with ejaculate, she experiences a destabilization of the fat cells recently ingested, causing them to reconfigure themselves in such a way as to appear to gain mass. this is actually a rather esoteric point, i won't bore you with the details, but the end result is that this fatty deposit is routed directly to certain, shall we say desirable, portions of the anatomy. i've seen this subject," she continued with a smirk, "and i can only describe the current proportions as mammoth." "this next vial," she continued, "is untested, but we're fairly sure it will work. it is the same thing in reverse, to transform a woman into a man. it contains also a compound which will cause penis growth, like the aforementioned breast and hip area growth, but in response to the chemicals released internally in a man during orgasm rather than from some outside source." "this next vial we are particularly proud of. it should alter the actual chemical configuration of the brain. as you know, the brain works on electrical pulses conveyed chemically, so this compound is designed to latch onto and stimulate the pleasure sensors of the brain when the brain itself receives certain stimuli. particularly, the first object that registers in the mind as a person that the subject sees after the drug is administered will be the stimuli. the subject will bond to that person like a baby duck bonds to it's mother at hatching, and their pleasure sensors will stimulate them while in the presence of that other person. i'm sure you can see the uses of these drugs as useful in all manner of brainwashing enterprises. now, if you'll follow me, i'll show you the next part of our facility..." she trailed off, leading the group out the door. i had marked very carefully which syringe she had said was the one to turn females into males. i walked slowly over to the table, realizing that my object was finally within my grasp! i could be a man again! suddenly, though, i remembered that i would not be my old self again. i would look like whatever they had genetically programmed into that drug. also, she had said something about penis growth occurring at each orgasm. did i really want my dick growing out of control, like my tits and ass were now? i realized that i was still doomed. suddenly, however, i got an idea. i took the syringe anyway, but didn't inject myself with it. i also took the syringe next to it, and quickly exited the building the way i had come in, returning to my dorm without incident. once there, i stripped down to bra and panties, and then lay back on my bed and removed those, becoming completely naked. i rubbed my huge tits, thinking that if all went well, this might be the last chance i had to play with them. my right hand slipped down to my cunt, and i masturbated myself as a woman for perhaps (hopefully!) the last time. i took tiffany's dildo from where i had left it lying next to the bed when i removed my panties, and began to ream my pussy furiously with it. after a while, i realized though that the sensation i wanted for my last female masturbation was that of my finger rubbing against my clit, so i removed the dildo and started to get myself off by hand. the feeling was amazing. as my transformation progressed, i had gotten more horny and also more sensitive to pleasure, and by now i was at a point where i was impossibly sensitive to sex. i was constantly turned on, craving cum, and the slightest touch to my clitoris could send me into shivers of ecstasy. there's no way to describe what it felt like; it was so much better than it had been when i was first changed into a woman that it was almost a different sensation. after fingering my clit for a while, i realized that my last masturbation as a girl wouldn't really be complete unless i finger fucked my asshole, so i lubed up my left hand with pussy juice and stuck it up into my ass. the hole was already loosened from the vibrator that had recently been buzzing away in there, as well as more than a week's worth of old fashioned buttfucking by thirty or so different guys. i stuck my finger all the way up into my ass, enjoying the full feeling there, and wiggled it around while i rubbed my clit with the other hand until i came. as was usual since my transformation into a woman, i was still horny. it suddenly occurred to me that since i would be turning back into a man later tonight, i could for the first time indulge my lust for cum without any fear of the consequences. certainly, my breasts and hips would grow as before, but any changes would be completely temporary, only lasting until later tonight when i was a man again. i jumped up from my bed and rushed to the room next door. the guys were laying in their beds, having turned in for the night. i knew they weren't expecting me to take any initiative; since the gang bang i hadn't been able to refuse a good fucking, but i still didn't seek it out, trying to slow the growth of my breasts. now, however, i didn't care. all i knew was that i had an insatiable thirst for cum and tonight i could do my best to quench it, knowing that the consequences would be only temporary. in fact, the small part of my mind that couldn't help enjoying the huge breasts i now possessed had me actually looking forward to my growth. i wondered how big they could actually get? i decided to find out. i went over to greg's bed and climbed on, pulling down the sheets to expose his already hard cock. i took it into my mouth immediately, sucking him as far as i could into my throat. since the gang bang, my only objective in having sex with these guys was to absorb their cum. it was all i wanted, orgasms were secondary almost to the point of unimportance. i sucked off greg's cock as quickly as i could, not even really interested when he woke up. all i knew was that for the first time since i had become a woman i was able to indulge my lust for cum without fear or the consequences, and i gloried in it. greg started to moan as he came the first time, and the noise he was making woke up his roommate. i didn't even acknowledge ian's existence, i just aimed greg's spurting cock so that it shot onto my breasts, and then took him back into my mouth. i needed more sperm. ian, being the ass crazy pervert that i had known he was, immediately got behind me and started fucking my pussy, staying in that hole only long enough to lubricate his dick before he drove his organ up into my anus. i ignored him, knowing that he was enjoying himself, and that his cum in my ass would intensify the lovely throbbing in my hips and breasts. once again, i could feel the lovely sensation of my breasts growing. this time, all i did was enjoy it without reservation. ian fucked my ass four times before he collapsed, and i managed to coax an unbelievable seven loads of greg's cum out of his dick and onto my tits, before he also collapsed. all through this episode, i was only able to think about my rapidly enlarging breasts. the sex was almost at the back of my mind; i enjoyed it in a completely different way, just as the impetus for making my tits grow. that was my real objective, and all i was really interested in. after i had gotten all the satisfaction from greg and ian that they were capable of giving, and my sperm craving was as satiated as it would ever be, i returned to my room. on the way, i stopped to check the size of my breasts in the mirror. they were gigantic. mounds of flesh stood out from my chest in a way that was completely unbelievable, so impossibly buoyant for their size that i would be convinced they were fake if they hadn't been mine. they were so large they must have made up half my weight, which must now be nearing one-eighty, which was what i had weighed as a man. tearing my gaze away from my awe-inspiring tits, i went into the room i shared with tiffany. she was lying naked on her bed, on her stomach with her ass sticking up into the air. seizing an opportunity, i grabbed the syringe with the mind control drug in it and injected it all into her ass. tiffany woke up from the sudden pain she felt in her right ass cheek, and started to fight against me, realizing what must be happening. i struggled to hold her down, with the weight of my tits on her chest being my only real advantage, but in my weakened female state she was much stronger than me. i struggled to overpower her, wondering how long it would be until the drug took effect, until suddenly and without warning, i felt her relax. i looked down into her face and saw her looking back at me with such a look of adoring, puppy-dog love that i knew she couldn't be faking. i immediately got up, went over to where i had hidden the syringes, and got the other one. i injected it's contents into her ass, and she didn't raise any protest at all. i was amazed at the results. i hadn't expected it to be this fast. within about ten minutes, the tiffany i knew disappeared and was replaced by a 6'5", muscular, well hung stud. the changes were just slow enough that you couldn't actually see them happening, but fast enough that you could close your eyes for a moment and reopen them to see an obviously more masculine figure standing in front of you. "tiffany," i started, eager to get some information before succumbing to what i knew would come next, "can you change me back into my male self?" i wanted to get right to the point, before the craving i now felt for tiffany's new cock took over. "certainly, chris," she replied. "you see, some of your cells didn't actually change. that would be impossible to implement, and it's unnecessary anyway, as long as the vast majority of them change. we've already formulated a drug that finds the oldest form of dna in the subject and reverts the subject to that form, for just such an eventuality. in fact..." "never mind," i interrupted. "right now, all i need is your cock." i crossed the room and pushed tiffany (it felt really weird to realize that this stud in front of my was my very feminine roommate. after a few minutes, i didn't care anymore, as her dick spurted it's first load onto my breasts. as it spurted, it began to lengthen, and i knew i had my revenge. i continued to suck tiff's cock, hardening it again, and rolling it around in my mouth to induce another orgasm. i noticed that the mostly depilitated hair pattern she had had on her pussy had carried over to her dick. it had a little triangular bit of fluff over the very base of it, and the rest was shaved clean. i was kind of glad, thinking how this was the last dick i would ever suck, and i really preferred them shaved. tiffany came again in less than five minutes of oral stimulation. i guessed that tiffany had as little chance of controlling her masculine urges as i had had of resisting my feminine ones. i aimed her dick at my tits again, spurting it's sperm where it would have the greatest effect, and went back to sucking her cock. when i had it hard again, laid back on tiffany's bed and pulled her on top of me. i actually allowed her to kiss me, the first time i had been kissed on the mouth by a man in my time as a woman. i guessed that since it was actually a woman, there was no problem. then i reached down to guide her inexpert but exuberant prick into my pussy. tiffany wasn't even as good of a fuck as ian, let alone greg, but all i really wanted was another load of cum, as well as to force her to have sex as the other sex just like she had forced me. if i had had more time i might have tried to get her gang raped by a bunch of horny girls, but actually that might have been too enjoyable for her, and in any case time was short. i allowed her to cum in my pussy, and then sucked her dick to another erection (it was bigger now, about fourteen inches long, and throbbing with the same rhythm as my tingling tits) and turned over onto my hands and knees, allowing tiffany to bang my asshole. she went to the work at hand with relish, but without subtlety. when she had cum her fourth load, up into my asshole, i exerted all my force of will and tore myself away from her cock. i got dressed and inserted the dildo and vibrator into myself as i had before, finding to my good fortune that tiffany had brought more, larger bras home for me, knowing that soon i would be too large for even the unrealistically large sizes i already had. i finally found myself strapping on an o cup bra, thinking to myself that i now probably had the largest tits in human history. i then forced tiffany to get dressed in clothes borrowed from greg (ian's clothes were too tight in the crotch) and lead me back to her laboratory. we returned to her lab without incident. on the way there, i was constantly finding my thoughts drifting to tiffany's now eighteen-inch cock. i changed my mind. i had originally intended to leave her as a man, but now i realized the advantages that a beautiful woman who was completely under my control could bring me. i decided to have tiffany turn herself back into her old self, so i could use her sexually like she had used me. we entered the room where i had been strapped down during my transformation into a woman, and tiffany immediately got out two doses of the antidote she had described to me. she administered the shots to each of us, assuring me that it would work as quickly as the other shots had worked on her, earlier. i lay down on the cot in the center of the room, stripped, and closed my eyes, waiting to open them as a man again. i must have dozed off, because the next thing i knew i was waking up. i sat up, immediately feeling disappointed. the huge weight on my chest was still there. i saw tiffany sitting naked over in the corner of the room, and she at least was back to her old self. "what went wrong?" i asked. "nothing," she replied. "we were both restored to our former genetic make-ups." "then why am i still a woman?" i asked. "you're not," she said, pointing at my crotch. i looked where she was pointing to see that she was correct, between my legs was now the seven- inch cock i had had before she kidnapped me and conducted her experiments on me. it was hairless, but i knew that hair would grow back. in fact, i had enjoyed having a hairless pussy so much, i might have considered the joys of a bald cock if i hadn't been so enraged by my other bodily attributes. "then why the hell do i still have these?" i asked angrily, grabbing my still humongous tits. she didn't answer at first, she just guided me over to a full length mirror set into the wall. i looked at myself in the mirror, realizing that i was a strange amalgamation of the man i had been born to be and the woman i had been turned into. i had a face that was almost my old one, but softened and feminized. i was also nearly my old height again, and i had a cock, but other than that my build was entirely female. my breasts looked only slightly smaller, but that was explainable by the fact that they were now on a much larger frame. my hips still flared out so much as to make my waist look impossibly thin. i turned around to look at my perfect ass. "now you've done it," i nearly screamed, really starting to get angry now. "i can' even lead as normal a life as i did when i was a woman. i'm some kind of she-male freak! how come what happened to me didn't happen to you? you don't still have a huge cock growing out of your bush!" "the same thing did happen to me," she said, sounding a little hurt at my abuse. her psyche had been altered by the drug so that she wanted to please me, and it was very disturbing for her to be yelled at. "look." she spread her legs to show me her clitoris, inflamed to seven or eight times it's normal size. "the gender swapping was a genetic change," she said, "but the penis, hip and breast growth was simply a rearrangement of fat molecules. it can be undone, but it takes a different drug." she rummaged around in a cabinet full of syringes for a few minutes, coming up with two syringes full of two different mixtures. "this one," she said, injecting herself with the first syringe, "will restore feminine attributes to its subject. and this," injecting me, "will restore your male ones." i waited for something to happen. "it's not working!" i exclaimed hotly after a few seconds. "of course not," she explained. "like the drugs we both experienced before, it needs sexual stimulation to have any effect." with that, she pushed me down onto the cot and strapped my arms and legs down. i knew that this was not a real imprisonment, but just a sexual game for our enjoyment, so i put up no resistance. she climbed onto the table, kneeling between my legs. i could actually see her elongated clit hanging between her legs like some tiny dick, but most of my vision was taken up by my huge mammaries. she snaked her way up onto my body and started to lick them. this was the first time i had had tits to be stimulated without the overriding horniness that had been triggered by my first transformation. before, i could blame my enjoyment of my tits on the physical and mental changes that had been forced on me. now, i had no such excuse. i must admit, it felt just as good, perhaps better, because i could concentrate on the sensations coming from my tits and not have to worry about a powerful need to cum or ingest sperm. tiffany was as expert as ever in manipulating my breasts, licking over the full masses of them. she scraped her teeth over them, nipping them gently, and sucked the nipples completely into her mouth, pinching them also slightly with her teeth. i moaned in ecstasy. she kneaded both my breasts in her hands while sucking them each in turn. she buried her face between them, pushing them up like earmuffs so that they almost enveloped her head. she took both nipples between the fingers of either hand, and suddenly pinched them tightly, rolling them back and forth between her fingers. that pitched me over the edge, and i came. i felt my cock spasm, cumming from the stimulation she had imposed on my breasts, and i shot my first load of cum in a week. it shot up and hit tiffany, and i heard her give a little "oh!" of pleasure. suddenly, my breasts and hips began to tingle again, but differently from before. as i looked at them, they deflated slightly. i looked up at tiffany to see her kneeling between my legs, both her hands at her crotch pulling her cuntlips open and exposing her clit. as i watched, it retracted slowly, becoming not so grossly out of proportion. tiffany was reacting to my cum as i had earlier reacted to hers. that last statement was truer than i knew. tiffany suddenly said to me "my tits feel funny," and we looked at them to see them grow ever-so- slightly larger. i realized that my cock had been tingling, and looked down at it. i wasn't sure, but it looked slightly larger too. in any case, there was nothing to be done about it now. i flipped tiffany over onto her back, the masculine strength starting to return to my arms, and inserted my cock into her pussy. i could still feel how my wide hips pushed her hips extra far apart, and my gigantic tits still cascaded down onto her chest, but now i was penetrating her with a real cock. tiffany, for her part seemed to be enjoying being fucked by a perverted she-male, as her hypertrophied clit was pushing up noticeably against my hairless cock. i reached around behind her to grab and spread her ass cheeks, pulling her cunt onto my dick with my grip on her ass as leverage. i strove to impale her upon my shaft. i was so entranced with again feeling the pleasure of entering a pussy that i wanted to push myself completely up into it. eventually, though, i began to stroke in and out normally. the mix of sensations was what made this fuck so fantastic. my dick was fucking a pussy just like it always had, but i could feel tiffany's hands on my extra wide hips, and my gigantic tits were constantly rubbing up against her smaller (but still very large) ones. the juxtaposition of feelings from my male sex life and my female one, and particularly that they were my favorite sensations from each, drove me wild. considering the tensions of the situation, and how horny we both were, it's not surprising that i couldn't hold out for very long. after ten minutes or so of squatting between this beautiful girl's legs, fucking her as a she-male, i came. as we both watched, my tits and her clit again shrank somewhat. i guided tiffany with my hands, flipping her over yet again so that she was on her hands and knees. i reached down between my legs and started to jack my dick (yes, it was now noticeably bigger) to another erection. looking down between my still huge tits (i estimated that they were now back down to l cups,) i saw my hand jacking my shaft. it was an incredible turn on to see that big cock, so incongruous with the rest of my body, which was so feminine. i jacked myself off for longer than was strictly necessary, enjoying the sensations and the arousing visual effect it had on me. eventually, i pushed the giant head of my well-lubricated cock up against tiffany's puckered asshole. with one thrust i buried my cock completely up her ass. the moan that forced itself past tiff's lips, half pleasure and half pain, was proof that i was butt-fucking her a little bit harder than she had intended. however, i was still a little bit enamoured or having my revenge on her, so i crammed my large cock up her ass and fucked her as hard as i could. my muscles were standing out more, growing closer to their former size with every orgasm i had, so i had even more strength with which to grasp her hips and pull her back onto me, impaling her anus on my dick. i stroked in and out of her asshole, enjoying the tightness i could feel there that was so much more intense than in her pussy. tiffany cried out more in pleasure than in pain now, as her sphincters relaxed to take the length and width of my cock into her tail more easily. i was still assaulting her ass with quite a lot of force, though, pushing her forward until she started to get closer and closer to the table. finally, she was just lying there on her stomach, and i was lying on top of her, my huge breasts rubbing and slipping around against her sweaty back. i forced my cock in and out of her ass, holding her cheeks apart as she lay there limp, offering no resistance as i pummeled and fucked her ass. i felt my orgasm grab me. it felt like it was picking my up and wringing me dry. i thrust my cock as far as i could up into tiffany's ass as time seemed to slow down. i could feel seconds flowing past like hours as my orgasm began. i could not remember ever having a stronger one, as a woman or as a man. it felt like the very essence of my being was being squeezed out through the hole at the end of my cock. finally, after an eternity in which my eyes squeezed shut and the whole world seemed centered around my cock, i could feel the release. my cum shot from my dick and up into tiffany's abdomen. i could hear and feel her moan her pleasure, and i felt my tits deflate slightly again as i collapsed on her back. well, it took all night and part of the next morning, but we finally got back to our right shapes. tiffany's clit was back to normal by the fifth fuck, but i lost count of how many times i had to come before i was completely male again. the side effects on both of us were considerable. i am now 6'4" tall, two inches taller than when this story started, and about twenty pounds heavier, all of it muscle. my dick is now twelve inches long (i'm sure of that figure; tiffany measured it,) and i've got a bit more body hair, except on my dick, which i now keep shaved bald. i decided that i liked the sensation. tiffany's changes are in the other direction. her tits grew two cup sizes, she's now a g cup, and her hips and ass filled out into a nice rounded package. i guess she's even more fuckable now than she was when i met her. i decided to stay roommates with tiff. as i said before, it was a coed dorm on a progressive university campus, and i enjoyed all the sex i got from her. we discovered that the growth effect on our sex organs was only temporary, but i know if we ever want changes in our bodies, that can be accomplished. since i drugged her, though, i'm also sure that tiffany wouldn't transform anyone without my permission. all in all, life is pretty good. i'm doing all right in my classes, and planning on majoring in biochemistry (i've got a great tutor.) i've been hanging out at the bar a lot with the guys from the room next door, but i tell them i don't believe their stories about tiffany's former roommate, some slutty girl with breasts that were amazingly huge. after all, shit like that can't be true, can it?

the end (?)
