I have been reading your site for a while and it always arouses me. One thing I have learned is that I enjoy reading stories about men or boys jerking off together. I never did that. I am happily married and very loyal.
A few weeks ago I went into the steam room of my gym and when I walked in it was obvious that the two guys in there had been fondling each other. They quickly covered up when I came in but I had no doubt what had been happening. In a flash I made a decision. I took my towel away and just rubbed myself a bit, casually, just as a way of saying it was ok if they continued. I sat far away but without my towel, and I let my hand run all over my body and rubbed my dick a little too.
In a few minutes they started to uncover and do the same thing, and not too much later they were back at each other. For every move they took with each other I got a little more aggressive with my own dick. I was worried that maybe they would come on to me as I had never experienced this before and didn't know what to expect but nothing like that happened. As they got hotter and heavier in their action so did I with my solo, and after a good while the two of them came at almost the same time, and by then I was going really strong and came not long after.
We all smiled very sweetly at each other afterwards and never said a word. I went back to the shower to clean up. That night I had the hottest sex with my wife that we had had in years, and she commented about it as she was overwhelmed. I feel I did not do anything wrong or disloyal, as all I did was watch. But it was so damn hot. I do not want to tell my wife why I was so hot that night, but it was from watching these guys and kind of being a part of it. I do not want anyone else touching me but I do want to keep watching this action if I get the chance again.
