I really don't know how this happened. I am married with children, and have never had a gay experience. I don't even particularly like the colleague in question, nor is he particularly attractive. He is in his mid-50s, average looking, and skinny as a rail. He probably weighs 115 pounds.
What happened was we were sitting at the lobby bar with a group of about 10. As time passed, people began drifting away until it was just he and I. We sat there drinking and watching TV for another 2 hours, and I was beginning to get lit. At this point, the hows and the whys are a little fuzzy, but suffice to say, I wound up on my knees in his hotel room with his cock in my mouth.
I must have done a pretty good job, because he came in my mouth after about only 2 minutes. What's worse is that I swallowed it. Voluntarily. He hadn't even asked.
Thank god we were going home the next day. I don't think I could have faced him. Or anyone else.
