When I was in college my roommate was one of my old friends from High School, I had a bit of a crush on him for years, but unfortunately, he was as straight as they come (LoL! I'm gay if you hadn't already figured that out). So, one evening he had been out to a party and staggers in drunk off his ass, he proceeds to strip down naked and fumble around for clean pair of boxers, after a few minutes he gives up and flops down buck naked on the couch. Through this whole episode I'm sitting behind my computer desk drooling with a raging boner. He's still laying they're on the couch and mumbling for a few minutes before he dozes off. Well I realize I'm so horned up I'm not going to get anything done until I get some relief. So, still sitting at the computer desk, I slip my dick out of my shorts and rub one out while looking at his naked body.
Do admit I felt a little scummy the next day. But after years of dreaming of seeing him naked that was one hell of knee-buckling orgasm.
