I am a straight married man but I have a secret in my past that no one knows about. Well, I guess the person who I was with knows about it.
I was about 10 years old when I first started having and going to sleepovers. I had one friend -- we'll call him Steve -- who was as curious and horny as I was at that time. Every sleepover we had was a jerk off fest. There was one time when it was a little different. A usual sleep over consisted of us watching movies in Steve's basement until his dad told us to go to sleep. Once in our sleeping bags we would start talking about girls and quietly jerk off.
Steve was always more impulsive than me and, on one particular occasion, Steve got out of his sleeping bag. He began walking around the basement with his hard on sticking out in front of him. Without much urging I was out of my sleeping bag and both of us were walking around with our hard-ons, or swords as we called them.
Eventually, and without much thought, we brought our swords together. We whacked them together and poked each other in the pelvic area. At one point they were pressed together so hard I thought mine would explode. I could see them clearly in the moonlight coming through the basement window and the sight nearly made me cum. I could feel the heat coming from his dick and could feel the soft skin. We stood like that for a few minutes not knowing what else to do. Then the moment broke and we laughed and went back to our respective sleeping bags. Once inside we didn't have to jerk off much more before we came. We both laughed again and fell asleep.
