...try changing his sex. As a 'weak' boy, Ty had been bullied for being 'girly' for years, and he'd always thought it was stupid. He'd started to think it was especially stupid after getting given 'the talk' and finding out things like how women can get pregnant and have children and how a woman's pleasure in orgasm is 10 times that of a man's, and even moreso since he'd started puberty and had become strongly attracted to them. It seemed like the perfect example of a big change to himself to investigate- to see what it'd be like to be herself.
Ty locked his door, undressed and stood in front of the mirror. "I wish I was a girl version of myself," he said. Like with Dustin, this time he didn't change instantaneously, but gradually. His figure seemed to contort subtly as his shoulders and upper body curved a little inwards and his hips and butt flared slightly outwards. His arms and legs seemed thinner, and his body hair had almost vanished except on his head, where it was lengthening past his shoulders. A shiver ran through his face, and when his eyes opened again he noticed even that had changed, his lips looking puffier and his cheeks softer.
By now Ty looked like a girl everywhere except his chest and crotch, and as these started to change he felt surprisingly intense arousal, pleasure and connection to femininity. Ty's nipples expanded and felt sensitive as they became erect, and the new hormones accumulating inside him made Ty understand this was a feeling only a female body could experience. Ty's soft hands moved to them and a soft moan emerged as he rubbed the sensitive teats, mounds of flesh budding under them that ached to be felt and pleasured.
While his chest grew, Ty suddenly felt his manhood start to shrink- but to his surprise, it didn't hurt or even feel scary. The hormones assured Ty that relinquishing his penis would grant greater pleasure and the ability to bear life. This knowledge allowed him to watch his cock shrink away with satisfaction, and when his balls moved inside him and his scrotum started reshaping from a sac into labial lips, the emasculation felt natural. In Ty's head, something clicked- she became female, a woman. Feminine terms felt like they fitted her perfectly. And just to affirm that, she felt her penis recede to a clitoris, her testicles connect up with a womb inside her and form ovaries, and a vaginal slit emerge from the centre of her former scrotum.
The intense transformative feelings finally stopped, and Ty smiled as she saw her new girl self in the mirror. She looked pretty, and felt comfortable with herself in a way she never had as a boy. She also realized her sexual fantasies seemed to have reversed, as she idly imagined handsome boys with big thick cocks. It took her a moment to realize that since he'd been a heterosexual boy, now she was a heterosexual girl.
She wondered what she do to experiment with her power next...
