The next morning, the boy Ty had slept with thanked her and made sure she'd been alright with everything, and then made an offer that Ty really liked the sound of. He suggested they could be friends with benefits if she wanted to. Ty said yes and gave him her number, and she got his- it turned out his name was Dan. He led her out of his place, and she assured him she could make her own way home, giving him a kiss goodbye and promising to text him once she was home safe.
Once she was back in her bedroom having sneaked in, she stripped off her girl's clothes and wished to turn back into a boy. And as she walked, she felt her body turn back into its old form- her breasts shrank away, her figure and muscles expanded, her pussy sealed up and her ovaries slid down inside to form his scrotum and testicles, and her clitoris swelled up into a penis. He sighed in his deepened masculine voice, both contented and weirdly disappointed to see his old self again. At least he knew he could move between the sexes at will. He got his phone once he'd dressed in boy's clothes and texted Dan to let him know she'd got home safely.

And for another, her fantasies about Dan while she was a girl were starting to bleed into his fantasies as a boy. He imagined the other boy making him suck his cock and fucking his ass, and when out of curiosity he decided to try jacking off to that idea he came faster than he had as a boy for a long time.
He'd kept texting Dan during this time, though obviously he hadn't told him any of this, and eventually just over a week later Dan sent a text asking, "Hey Ty do you maybe wanna come over tonight? I miss you
