I’ve had a few, but probably the most embarrassing was a few years ago while on a business trip with two of my supposedly straight colleagues. We were all staying at the same hotel (separate rooms) and decided after we got back from the work dinner with the client to all hit the hotel gym together for an evening workout. We had the place to ourselves and it turned out that there was a sauna in the men’s locker room. After our workout we decided to use the sauna and sit and talk about the next days presentation. Because it was late in the evening, the batch of fresh towels had not arrived and there were only a few clean towels to be found and we needed them for our post workout shower, so we decided to just go into the sauna naked and each sit on a clean washcloth again, saving the full sized towels to dry off after our shower. Well sitting there in the heat, post workout blood flow at maximum, I watched as all three of our cocks started to plump up a bit. The only thing was, my two colleagues stayed at a healthy semi, hanging down between their legs as we sat and talked, but mine continued to rise. Within a minute or two I was at full erection pointing straight up. At first they didn’t say anything about it, but it was hard to ignore and Matt made a comment. I just said that I’d not cum in a few days and that the heat must be making it hard. Thankfully no other guests entered. It finally subsided to a semi and we finished and showered and went to our separate rooms. Well about ten minutes later, there was a knock on my door and it was Matt saying he wanted to go over something for the next days meeting. He mentioned that he also had not cum in a few days. Needless to say, we jerked off and sucked each other on the hotel bed.
