...change his gender. He'd wondered a lot what it was like to be a girl and what he would've looked like, so that option stood out to him. He clicked it and then clicked 'no' to a pop-up asking if it should be permanent.
For a moment, nothing seemed to happen, and he wondered if this thing didn't actually work. But then an odd sensation swept through his body, and he started breathing heavily as unfamiliar hormones seemed to permeate through his body. His clothes felt uncomfortable against his skin, so he undressed both to ease the tension and to get a better look at what was happening to his body, standing in front of the mirror on his closet door.
This gave him a perfect vantage point to watch as he slowly transformed from male to female. His proportions shrank slightly all over, his figure slimming, his height reducing, his arm and leg muscles turning more lithe and even his hands and feet resizing.
A shiver ran through his face and his features subtly reshaped, his jawline softened and his lips puffed out, while his neck shrank and the bulge of his larynx vanished, with his voice's masculine baritone dissipating in tandem with it.
The changes seemed to assert sex change more and more as they progressed. His skin now seemed to turn more supple and smoothed out, most of his body hair thinning or vanishing altogether. His shoulders shifted inwards while his hips widened, his butt expanding to accompany it.
By now all but his actual sex characteristics had feminized, and as the Chronivac set about correcting this Bryan felt indescribably strong waves of arousal overcome him. An erogenous zone was forming in his chest, and his nipples rapidly grew sensitive and erect. He rubbed them out of curiosity and arousal, and they swelled in response, the once tiny nubs now large and aching to be satisfied. Under them mammary glands formed and soft breast flesh emerged rapidly, until the young man- such as she was- had pert C-cups.
Only the hard penis between his legs still looked or felt like part of a man, and as it started to retreat it shocked him how good it felt. In her head the confusion over his identity rapidly faded, making the sense of emasculation and castration from losing his penis and testicles actively gratifying. His shaft turned more and more sensitive as it shrank away into her, turning from a phallus into a clitoral nub, and his balls pulled up inside the body to form her ovaries while his scrotum sucked inwards and peeled open into her vagina.
Bryony stared at herself in amazement as she started to come down from the high of the transformation. She really had turned into a woman, both how she looked and how she felt. It was as if she'd always been this way and the man she'd been a few minutes ago had never existed, even though she remembered being him. She wondered what to do with her transformed body...
