Horny Friend at Sleepover

One night I was staying at a friend's house and we were watching late night TV, and he switched onto softcore porn. He had cable and I'd not seen anything like it. We were both horny - I was hard, he was I think, but we let it go. We were staying in the same bed that night and I wanted to sleep, so he stayed up while I turned over and went to sleep.

About 45 minutes later I woke up feeling something. I was on my side facing away from him, and all I could feel was him up against me humping my ass through my boxers. I jolted awake and reached to feel his cock - he'd taken his boxers off. He gasped and started apologising profusely and I laughed and said "whatever dude, I don't mind". I was hard too and he slowly started rubbing his cock and balls against my ass. I pulled my boxers down and in about ten seconds he moaned and spurted cum all up my back and over my ass.

He said sorry for making a mess and said "why not do it too?" He turned around but I pushed him on his front and straddled his ass and rubbed my cock and balls up and down his ass crack and must have cum in about 15 seconds. My cum went all up his back as high as his shoulders.

We didn't talk about it for a while but in our next sleepover we ended up doing the same thing... The time after we used our mouths. So started our first proper experience!
