Ty had always wondered what it would be like to be a girl - specifically what a vagina would feel like. He had never been particularly well endowed, a fact that Dustin rarely let him forget, and he was beginning to become unsure about his sexuality. He didn't want to become a girl all at once though, so eventually he made his mind up to start with just adding a vagina to his crotch, behind his balls. He stripped, putting his clothes carefully on his bed, and thought to himself about getting a new vagina.
Suddenly, he felt warm and tingly between his legs. He sat down on his bed to get a clearer view, becoming more aroused by the second. His penis rose up, looking bigger than ever as he resisted the urge to touch it! He stroked his cock gently, which seemed to excite him more than usual. He could feel his arousal growing not only in his cock, but also a growing arousal around his taint. He reached behind his scrotum to feel this growing arousal and could feel his skin pulling into his growing hole as he could feel his new opening growing and forming into a working vagina, with labia and clitoris forming around his probing fingers, which were pressing deep into his fresh vaginal opening as he felt like he was about to cum. Finally, he was overcome with a wave of pleasure unlike anything he had experienced before, his new, moist, female lips contracted, sucking his fingers in deeper as he moaned in ecstasy as his stiff member releasing his load and he cums all over his hands and stomach.
A few moments later and after a few more orgasms, Ty lay resting on his bed, wondering what he should do next. Firstly, he decided to get used to his new sex. He got up and had a look in his mirror. It was strange, Ty looked exactly the same everywhere, until you look behind his sack. In addition to his modest 6 inches of rod, he now also had a narrow slit. It was quite hard to see, so he moved his desk chair, spread his legs and lifted his balls. It was a slightly darker color than the rest of is skin, with pale pink lips which could only be seen if he moved his head as close as possible. There was a small lump hidden between the flaps, about the size of a jelly bean, but it felt just as sensitive as his penis above it. He guessed correctly that this was his clitoris. He subconsciously began to dive deeper, but was suddenly interrupted by a grouchy voice:
"Ty, get down here, you're going to be late!"
Ty looked around his room quickly, scrambling to get dressed. He contemplated wishing up panties to wear instead of boxers, but then realized that that probably wouldn't work well with his male equipment still at his crotch. He opts to continue using boxers for the time being. Then he wondered: could he get away with keeping his new vagina hidden, would anyone but him notice the oh so subtle change?
