I was living with my best friend and although we were both straight, we would sometimes rent porn and watch it together. On several nights, after smoking a LOT of weed and striking out at the bar, he or I would grab a movie and pop it in the VCR and have our fantasy girlfriends do what we wanted. Most of the time we would go to our separate rooms at some point and I'm sure he did the same thing I did...jack off and cum hard.
One night, I got back before he did and started to watch one of my favorites. I got semi-hard and pulled out my dick and started trying to beat off. I must have drunk too much cuz I wasn't having much luck getting it hard enough that I could cum. Frustrated, I sat there and stroked and watched the movie and at some point, I fell asleep. I woke up later, hand still wrapped around my dick and saw Jim silhouetted against the TV. He had his pants down and was jerking furiously! I was kind of freaked out especially sine he was easily as big as his nickname "beast" implied but didn't know what to do. If I got up, it would have been awkward in the extreme so I pretended to still be asleep and at some time I must have dozed off again. I woke up suddenly when I heard Jim grunt and then felt something hot and wet splash against my dick and hand! I opened my eyes wide and started to yell at him, to ask him what the fuck he thought he was doing but as I opened my mouth to yell at him, he let go with another spurt and it hit me on my chest, chin, and a few drops landed in my mouth!
That's when I did yell and he started laughing so hard that he couldn't stand up and fell next to the TV. I got up, still yelling and went to the bathroom to wash his cum off of me. Jim lay there laughing. When I got back, Jim was asleep. I tried to wake him up but he was gone to the world.
Pissed and somewhat sober, I went upstairs We lived in a basement apartment and the upstairs tenants were 2 ok looking blondes. Kathy was sitting on her back porch (our front porch) drinking a beer when I came out. She asked what the yelling was about and I mumbled something. she offered a beer and we sat there while I got drunk again and she rattled on about her job. At some point, she left and I sat there thinking about what had happened earlier with Jim and I suddenly realized that was finally rock hard.
