When he started out a “man”, he was clearly not masculine in the slightest way, but he had a little body hair. No one discussed or thought about his hole, and it only winked open, having only been stretched by the fingers and hair brush handles he had satisfied it with. Then as he became a “boy” all of his body hair disappeared. His cock was hard all the time. His hole became regularly used for the pleasure of real Men, who mostly referred to it as his “boy hole”, until, as he became smoother and smoother, a few began to refer to it as his “boy cunt”. He began to dress to show off his butt specifically, and began consciously trying to attract men. As he transitioned to being a “boi”, he became able to cum only when a cock was slamming away at his “pussy”, what nearly every Man called it now. He became very sensitive about his figure, and he became slimmer and slimmer, and lost any of the minimal muscle mass he might once have had. Since physiologically his body was naturally suited to the transition that was occurring, his butt remained round and protruding, even as the muscle tone disappeared. It softened considerably, and it was well on its way to becoming a natural cushion to the pounding of Men’s hips. After several months of being a “boi”, his brain associated being fucked exclusively with sexual pleasure, and his cock began cumming without bothering to get hard first. When it did, it was referred to as a “clit”. His “pussy” was loosening, becoming a soft, pliable entrance. His “pussy lips” became more noticeable, especially when they became engorged when he was aroused. As this continued the men who used him began calling him a “gurl” more frequently than a “boi”. He became perpetually preoccupied with making a cock hard and pleasing it, to the point where every dim thought he had revolved around Men and their cocks, such that when Men began telling him that he had a “bimbo brain”, he was relieved to have his condition explained to him in a manner he could understand, and this contributed to him thinking of himself as a “she” rather than a “he”. Her “clit” was merely a mild distraction now, it never made any effort to become erect, and the muted sensations it could provide were no match to the all consuming pleasure his increasingly sensitive “twat” generated, heightened by his body naturally directing all of the increased blood flow to his now prominent “pussy lips”, which ringed his loose, relaxed welcoming fuck hole. He now thought of his “twat” as much more of an entrance to his body than an exit, and it was used as such much more often as well. As his “clit” never became erect any longer, his insignificant balls began to shrink, which pleased her as they took on a more feminine appearance. As did her ass, which was now a soft, beautifully round object of desire for any Man. But neither her ass nor her over used, stretched, pinched, abused, swollen and sensitive nipples were prominent enough for her taste. In her slow “bimbo brain” she reasoned that while men found them arousing now, they would find them even more arousing if they were larger. So she sobbed with joy when Men offered her hormones which they explained to her would make not only both her nipples and buns larger, but also her clit and “ovaries” smaller. From this point forward, she will laugh and cry with delight as her body responds remarkably quickly, thrilling when Men tell her that the hormones make more visible changes in her body than in any they’d seen before, her sensitive, budding chest swelling with pride when they explain the reason is her body had simply always been meant to be supplemented with female hormones. And she is filled with determination and hope when they tell her that maybe, just maybe, if her ass and tits get big enough, and her clit and ovaries get small enough, someday, if she tries hard enough, and enough cum gets pumped into her twat, she just might be able to get pregnant and have a baby.
