Some of the replies here about being supposedly straight and either too drunk to say NO or too drunk that you said YES, stirred a memory. Years ago I was on this business trip with a coworker, a three week work assignment. We would hit the Gentlemen Clubs every night and drink a lot. One night during the second week, I got real wasted, which I seldom did. My coworker had to help me to my room, fish in my pants pocket for the key and put me to bed. I remember being undressed and I remember thinking that I was grateful that someone was helping me, as I was in a suit and tie. The only other thing I remembered was my underwear being pulled down and his hand on my dick. I think he tried to suck my dick. I truly don't know if he did or I dreamed it. The next thing I remember was him waking me up at 7 in the morning ( we had a door between our rooms) I started thinking about the night before and remembered that he put me to bed. Then I thought about someone sucking my dick. He never said a word, even about the fact that I got real drunk or had to be put to bed. As I got in the shower, I looked at my pubes for dried jizz or something. I even checked the sheets, underwear and found nothing. I didn't know what to think.
I was becoming bi back then, but this guy had a girlfriend at home and I know he screwed two girls from the district office while we were on the trip. He was sorta handsome and always gave the impression he got a lot of ass, always hitting on women. We never discussed my sexual orientation but I would assume that people where I worked figured that I might be "sorta gay", probably before I did.
The funny thing was that by the middle of the day after trying to sort this all out, I found that I was the one that was uncomfortable and found it hard to make eye contact with him. He was just the same guy and didn't act any different. It kinda complicated the rest of the trip. I would have been a willing participant if I hadn't passed out, but I know that when I do pass out, a bomb could go off and I wouldn't wake up. Before and after that, we sat around on the beds many times in our jockey shorts and I had been eyeing the fact that he had huge head outlined in his shorts. I imagine that it was a fat beer can dick, thinking that I would love to have a few slides on it. But, instead he got me and I got nothing. Sometimes, I am sure this happened because I remember the sensation that I was so drunk and that I couldn't react to what he was doing. I am sure that I couldn't have cum in that condition. Then again, sometimes I think I dreamed it all up. But, as I write this, I am sure he got in my pants. He's now married and has a family.
This share probably belongs in the "abused while sleeping" category but hearing shares about "straight guys" being blown while drunk made me think of this. Kinda of a twist, I think
