Ty continued watching the news, figuring it might give him some ideas. Suddenly, a story came on about a girl his age who was a social media star.
That gave Ty an idea: how about he tried turning into a girl for a while? He felt like it might be fun to become popular with guys like they could be, and to be honest he felt kinda jealous of how much closer they seemed to each other than boys did.
He decided it'd be fun to watch this change happen, so he wished no one would be able to interrupt or see his changes, and then got up, walked over to the mirror in his room and stripped naked. Gazing at himself, he thought, "I wish I was a popular girl at school."
A shiver of anticipation raced through his body, and everything started to feel fuzzy as the hormonal balance in his body rapidly changed. His skin rapidly felt softer and smoother, and his muscle mass decreased, his arms and legs turning more lithe and shapely while his hands and feet noticeably shrank. His shoulders narrowed and his figure slimmed, while his butt grew more pronounced and his hips widened. Even his facial features seemed subtly different, his lips slightly puffier and his jawline softer. He swallowed and felt his larynx shrink, the bulge vanishing from his throat and his voice rising a few octaves.
At last the change moved to his reproductive system. He gasped in excitement as his nipples surged with sensitivity and swelled, new desires emerging in his mind- the urge to have them rubbed, pinched, pulled, sucked, bitten. Mounds of flesh formed around them and rapidly budded outwards, softer and warmer and more sensitive than anything he'd ever felt, even more sensitive than his hard penis.
All of a sudden, he gave a little groan as something tugged his balls up inside him, starting to reshape them. She peered over her new breasts to see his shaft slowly vanishing inside her with it. Her sexual desires were shifting, not merely her sexuality but her physiological needs- instead of wanting his shaft to rub things and be inside them, she felt her body needed to take things inside of it and be filled. As his shaft shrank back into her, her body was forming a fuckable passage, moistening it to take an insertion. When what had been his penis finally slid into place as her clitoris, what had been his scrotum parted and finished forming her vaginal lips.
She looked at her newly-formed girl's body, and smiled. She looked very pretty, and any guy would be hard-pressed not to feel attracted to her. Now she'd finished changing, she wondered what to do...
