Nick looked in every room.
"Twerp left without saying goodbye. Good thing too. I am fucking horny, and I couldn't jack off with family around," Nick said aloud. Then he began tugging on his cock. He didn't know when Jeff or his folks would be back, so he needed to work fast.
He was already hard when he flopped down on the mattress. He pulled Jeff out and started pumping in earnest.
Jeff was conflicted. Full of Nick's blood was giving him such a headrush. He was high, this felt great, but he was embarrassed too. Suddenly, Jeff realized that Nick was in Jeff's room, not his own. He was jerking off in Jeff's bed. Had he done this before? Jeff was angry. Nick came.
Splooge.
Jeff was gushing up thick hot gooey porridge. It got all over his face and body. Yuck, what a mess. The head rush was gone. Jeff was exhausted. He wanted to get cleaned up and sleep. Mostly he wanted to sleep.
Nick got up. Grabbing Jeff's pillow, he wiped his cock and abs off on the underside of the pillow and put it back on Jeff's bed. He patted it and chuckled, "Pleasant dreams, Jeffy. Maybe if you made your bed when you got up, things like this wouldn't happen."
Nick walked naked back to his own room. His bed was nearly made. Nick's words echoed in Jeff's mind as he shrank beneath Nick's foreskin. Nice and warm and cozy. "Pleasant dreams, Jeffy."
Nick was staring at his worm in his bedroom mirror. It must've always looked like that. Except he felt certain he had been circumcised. He had teased Jeff about not be cut like he was. Except Nick could see and knew that he was uncut. He was confused. Having a foreskin felt so wrong, but (as he ran his fingers over the velvety sheath) it felt so good too.
