A couple years back I was traveling quite a bit for work often with a coworker friend who my wife and I went to school with. One weekend trip my wife was along and we ended up having a threesome and have been together several times since which is always a blast. One night he and I were on a trip and were back in our room having a few beers when the conversation turned to sex with my wife and we even called her to tease her. She wasn't amused and cut the call short so there we were, comfortable with each other obviously and the more we drank and talked the hornier I got, I got up to get a beer and my buddy noticed my hardon, asking what I planned to do with it. I dropped my boxers and stroked it a little and asked him if he was hard, he said no and I challenged him so he stood up and slid his drawers down revealing a limp dick. I said it was a shame, he asked why, I laughed and said I might blow him if he was as horny as me. I don't know why I said it because I had never sucked a guy before but he replied what's stopping you, I said I was only kidding but maybe I would. With that he walked over and said have at it so I knelt down and took his dick in my mouth. It was awkward at first but he was getting hard and I was starting to enjoy it and it seemed like a short time passed and he said he was going to cum. I backed off at first but thought what the hell and didn't want to spoil his fun and soon felt a blast of hot cum against the back of my throat then a few more. I swallowed and licked him clean then he returned the favor, we have had fun sucking each other several times since. I don't think I'm gay and don't have a desire for another guy but it is what it is
