Something like that happened with me after a cousin's party, except I was only pretending to be asleep until he had fully unloaded me. Then I "woke up" and told him it would cost him his arse, if he didn't want me to tell my auntie / his mother. Oddly enough, one of the best wanks I've ever had. Shagging his butt wasn't bad, either. And it wasn't his first time, either.
Ar the start of my freshman year I got way too drunk and passed out at a small party . I woke up the next morning and went to take a piss I discovered what little amount of pubic hair had been shaved completely off and I looked like I had a year and half earlier. I was so embarrassed two days later when having to shower after gym class as I was the only guy who appeared not to have started puberty.
I never believed that this type of video was legitimate (afterall, who would not wake immediately when someone touched his dick??). UNTIL, I was at a party recently where a high school kid was passed out like this kid, and had a boner in his jeans....and his buds stripped down his pants and 1. cummed on his cock and balls, and 2. painted his cock bright green with (water colors) paint. PS, the dude (16yo) was hung rather well, really well.
so much fun to touch ...
