Jake liked cocks. He managed to keep it secret because he was a straight acting jock and he didn't want to have sex with any of his teammates. He just wanted to play with their cocks. There were times when seeing a teammates cock dangling near him tempted him to want to grab it but then again, as a straight acting jock, there were times when he could get away with grabbing a teammates cock and they'd think it was just a prank.
Jake's new cock was huge, larger than any he'd ever seen, especially in width. His balls had also grown mostly in length of hang. It looked like a normal cock except for the size and facial features but even the facial features were barely noticeable. When the cock closed it's eyes, it's eyes and ears disappeared. When the cock closed it's mouth, it's mouth and nose disappeared and a normal piss slit appeared instead. Jake stuck the tip of his pinky in the slit. He wasn't trying to masturbate. He just needed to explore this new monstrosity.
With Jake's finger tip in the slit, Mike felt like he had a large gag in his mouth but it also felt incredibly good. Mike the cock felt himself growing harder. With Jake's other hand, he gently pulled on his balls which felt to Mike like his entire crotch was being stimulated. Jake switched from fingering his slit to squeezing his glans which still left Mike muffled but Mike tasted pre-cum drooling out of his mouth.
When Jake switched to a full masturbatory stroke, Mike could finally use his mouth to speak. He yelled, "Get your fucking hands off me." But it was too late. The gush of cum flowed out naturally. Mike's entire cock body spasmed with orgasm. He shot five spurts of cum. Then he felt faint. He tried to speak but the cum in his mouth was like honey coating everything.
Jake asked, "How did this happen?"
Mike said, "I don't know. Tom, Stu and I thought about going surfing and Tom suggested some ridiculous, full-body wetsuits but then Tom and Stu disappeared and I turned into a banana that you ate turning me into your cock. Now keep your fucking hands off me. That was gross."
Jake said, "Sorry, let me clean you up." Jake had aimed into the urinal so there wasn't much mess but he moved to the sink and mirror. Mike got a good look at himself.
Jake turned on the sink but Mike said, "Don't wash me."
Jake asked, "How do you expect to clean yourself?"
Mike said, "Alright but don't touch my genitals."
Jake said, "But that's all you are."
Jake was gentle and it felt really good. Mike began to harden again but Mike yelled for Jake to stop.
