I am a straight married man, but was curious about an area of woods in a large park in town that I had heard was where men went for anonymous sex. One day I was nearby and decided to walk through the woods just to see if anything went on. There was a series of small trails leading in many directions through dense bush - a very private setting. As I watched from a distance I saw several men, of varying ages from 25ish to 65ish appearing and disappearing down various paths. It took some courage, but I headed in on one of the trails.
The trail took several loops and bends and there was nothing and nobody to be seen until I turned one bend. Ahead of me were three me men. Two were standing, one with his back to me and one sideways to me. The third was sitting on a fallen log in front of the man whose back was to me. It was pretty obvious that the one sitting was sucking the cock of one of the guys and the other guy had his out and was stroking it. I held back until one of them waved me to come toward them.
I walked up to them and the guy sitting was taking turns sucking each of the others. One was circumcised and his cock looked about the same size as mine. The other wasn't circumcises and his cock looked to be as big around as a beer can. Nobody seemed to mind me watching so I took my cock out and starting stroking while taking in all the action. A fourth guy came by. He had sweat pants on and reached into them and started stroking, but he never showed us his cock.
I started to get embarrassed, and was scared about what might be expected of me. I sure didn't want to get a disease, but I sure was horny watching. I stuck my cock back in my pants and left. I walked around a couple of more bends where it was private, took it out again and shot my load in about 5 strokes. Then I left. I haven't been back, but some horny day I am sure I will.
