...a young man about his age. This boy had started to become unsure of his gender and sexuality- like most boys, he felt attracted to girls, but he also had feelings for boys, and those feelings weren't just desires for homosexual sex with boys, but for the ability to have heterosexual sex with them and homosexual sex with girls. At this particular moment, he looked at his body in the mirror with a sense of confusion and uncertainty. He wished to know for sure how he felt about his gender, and to have a body that he felt comfortable with at any given time
As Ty's wish washed over him, his wishes were granted. He felt an intense wave of sensations fill his body and mind, and watched in wonder as his body capitulated to them. His figure slimmed and grew curvy and pretty, his shoulders narrowed as his hips widened, his chest swelled before his eyes and grew scores of times more sensitive, and his penis shrank rapidly to a nub, his crotch flattening to a subtle mound and a pair of lips and an opening forming at its epicentre. This was a female body. She had become a girl.
She felt a brief twinge of fear, wondering if this was permanent, and as if to answer her her body returned to its masculine form. Her figure firmed up and its curves vanished, her breasts shrank back into a flat chest, her vaginal mound sealed up and balls moved into it, and her clitoris rapidly swelled into a penis. He realized this power was his to control, and felt like he could cry of happiness.
Ty watched contentedly as the boy turned himself into a girl and herself into a boy, and experimented with her powers and how they impacted the world.
