As soon as Jen had gone around a corner Jake stopped and slid his hand's down his pants. He found his package exactly where it was supposed to be. Relieved he gave it a quick grab and exhaled, he hadn't even noticed he'd been holding his breath. Then he felt something and his heart skipped a beat. His penis was moving even while he was holding it. No... not moving. Shrinking? NO F**KING WAY!
Jake saw the men's bathroom a few steps away, burst in and pulled down his pants and underwear right there. He watched as his penis was slowly shrinking 5”, 4.5” 4” “No No NO!” Jake tried Grabbing on to it to stop it from receding further but this only made it go faster 3”, 2”, 1” and then it was flat. No cock, no balls. For several seconds he explored his bizarre sexless groin. It felt mildly sensitive to the touch, but not concentrated like the sensations from his penis. He looked like a life sized ken doll at the moment. He surprised himself further and laughed a little as he found the skin to be a bit ticklish too.
He felt a small dimple in his groin which made him very curious. As he explored it with his finger it was getting bigger. He pushed it in a little and then POP! Jake gasped as a really weird sensation overtook his body. He felt his groin split open and cool air rushed inside. His insides shifted too, he wasn't sure how complete the change was but it seemed to be a bit more than just superficial. He glanced at himself in the mirror as the changes slowed and took stock. His face was still the same. He flexed his arms, they were the same. His legs were the same, still the same runners build. He lifted his shirt, he was glad to see he had the 4 pack he'd been working on without too much success, and the small patch of chest hair and beginnings of a treasure trail... but the treasure trail went down to a sight that blew his mind, His penis and balls were gone, and in their place was his very own vagina. It had happened just like kyle said it would and he was fully himself, and he was a generally attractive guy despite the change of his genitals.
He spoke out loud “Now what?”
