Now that was out of the way, Greg decided it might be nice to do some experimenting. One idea in particular stood out to him, something he'd wondered for years- what if he'd been a girl? He had never quite felt comfortable as a boy; a part of him even felt a little guilt that that bastard had made his mom have a boy. Ever since his sexuality emerged during puberty, he'd been kinda distant from her because of his sex. He felt like it might be nicer, or at least interesting, to be a girl instead.
Preparing to make the change, he locked his door, undressed and then typed, "I am now female instead of male, and have all the knowledge I will need to comfortably live as a girl instead of a boy."
After hitting Enter, Greg stood shakily and turned to look at his naked body in his room's mirror. Before his eyes, he saw his sex invert itself. His facial structure altered to be less angular and more soft, the bulge vanishing from his neck and his voice increasing in pitch while his lips grew puffier and his hair lengthened down toward his back.
His figure slunk inwards and turned more petite, as he formed narrow shoulders, wide hips, lithe arms and legs, and smaller hands and feet. Much of his body hair vanished and his skin turned more supple and smooth.
At last the Chronivac allowed him to relinquish the Y chromosome he had been given by his biological father, and he slowly became she. His nipples grew puffy and erect, and soft flesh formed at his chests as breasts developed. His penis receded into her body rapidly, the shaft vanishing while the head formed a clitoris, and his testicles reshaped into ovaries and moved up to link to a womb while his scrotum sank inwards and formed a vagina.
Grace, as she was known in this body, slowly managed to focus again having finished changing sex, and she stared at her now female body. She loved how she looked, not simply because she had an impressive figure as a girl but because it felt right to her to be female instead of male, moreso than she'd even hoped for.
