Ty decided to keep his vagina after that. He enjoyed the freedom of not having his former junk dangling between his legs, though it was still a little tough to piss sitting down. Nick was also alright with it and the two had regular 'jack off' sessions, though it was a little awkward how he had a pussy during this.
What Ty had also discovered was that he was no longer making testosterone due to his new ovaries. This came as quite the surprise when Nick started gaining chest hair and Ty had his abs grow out into a tiny pair of boobs. These boobs were't even A-cups, but they were warm and squishy, something Ty liked to play with when he had the chance. Ty realized his new hormones were turning him into a girl, and he wanted to see how long it would take. Already by the near end of summer Ty's breaths had grown to a small a-cup and he'd slimmed down immensely to an androgynous figure compared to Nick's hulking stature.
In Ty's opinion it turned him on seeing Nick in all his glory. Ty was becoming a Teenage girl and Nick was the perfect partner to fuck him. And he wanted it soon.
