One idea really stood out to Ty- what if he used his power to turn into a girl? He had never fit in well with other boys at school, and since puberty had started for him, he'd felt kind of uncomfortable with himself. Did he want to be a man or a woman? He had trouble telling. But one thing he did know, and didn't like, was that he didn't feel comfortable about the possibility of being trans- he wasn't sure if he'd like to be a girl, and knew his foster family and most of the people he knew at school wouldn't support him.
He felt like getting to try being a girl for a while might clear up his confusion, and at least it'd be a fun way to try out his powers. So he took a deep breath and said, 'I wish I'd turn into a female version of myself.'
A strange vision shot through his head- an egg getting surrounded by sperm, one of them seeming about to get inside and fertilize it only to falter and get surpassed by another one. Ty understood what this was- instead of the sperm which he grew from having a Y chromosome, now it was one with an X chromosome.
The vision faded and Ty found himself in his room again, the waves of pleasure flowing through his body again as he saw it start changing into her body. His faint layer of body hair receded into his skin, which softened all other- his body felt smooth and supple to the touch. His figure got more petite and curvy, his arm and leg muscles turning more lithe, his hands and feet daintier, his torso and shoulders sucked inwards and his hips flared outwards.
A shiver passed through his facial muscles as his face began to feminize. He saw his cheeks soften, his jawline round, his hair lengthen and his lips turn puffier. He swallowed hard and noticed his voice's pitch heighten, realizing a moment later his larynx had shrunk. Looking at his face in the mirror, it felt strange to consider Ty still looked like himself, but not like a man or even a boy.
At last the changes reached Ty's reproductive system, truly making him change from male to female. He felt when his testicles shrank and pinched up, and with two wet pops they moved up inside his body! As his sperm rapidly died off and his gonads altered to produce ova instead, the young man felt emasculated, relinquishing his manhood and aching to embrace her womanhood.
Fittingly, his body continued reshaping to a feminine form. He felt his chest grow warm and sensitive, and saw his nipples widen and lengthen as they became erect. Soft flesh expanded out around them, and Ty recognized she was sprouting breasts. Soon pert C-cups hung from her chest, perfect for her lovers to cup and her offspring to suckle on.
The last vestige of his manhood now gave way- his 9-inch penis began retracting slowly, its sensitivity mounting as the nerve endings bound up tighter and tighter, and his loose scrotum reshaped into lips which her vaginal opening formed inside. Soon Ty had formed a clitoris and a pussy.
Once she had finished transforming, Ty stared at her reflection for a few seconds, astonished that the person she saw was her. She'd really turned into a girl, and she...
