First time stroke with another guy

When I was about 16 I went on a summer trip to the beach with my sister, a bunch of her friends and a friend of mine. My friend and I shared one room and the girls camped out in the living room. Well, my friend was HOT for one of the girls and we started talking about her the minute we settled into our room. Later that night, as we settled into bed (we were sharing a bed) we began talking about her and how hot she looked in a bathing suit. We we both starting to get hard and were "secretly" playing with ourselves under the sheet. After about 15 minutes of this he pulled back the sheet unexpectedly and said he was too horny and had to masturbate. I had never done this in fron of someone before and was a little shy. He said he had done this with his brother many times and even a couple of mutual friends of ours. I was rock hard! There was no way I could contain my excitement. I pulled down my shorts and soon we were both stroking and talking about my sister's friend. I was so excited about seeing another guy stroking his cock right in front of me that I could hardly keep myself from squirting right away. I watched him stroke his meat and noted the way he did it which was way different than me. I like the back hand method and he held his hand flat out and rigid and rubbed it back and forth on the underside of his HUGE cock pressing it against his stomach. We stroked ourselves for about 10 minutes and he started breathing really heavy and I knew he was going to cum really hard. I waited and he started bucking and I knew this was it. As it turned out he hadn't really started ejaculating seamen yet and only a few drops came out. I knew that I was a regular Peter North and could drown most porn stars in my load (as I had done many times in my stroking fantasies:) so I was a little self conscious as I was nearing my climax. I couldn't hold it anymore and let out a huge moan follwed by a gallon of cum all over my stomach. He just stared at it in disbelief and when I was finished I noticed his staring and asked if his brother came a lot. He told me that his brother and he stayed on their own beds and never really saw each other. For the next couple of weeks we met regularly in his bedroom and shared erotic stories while we both jerked in front of each other. Then it abruptly stopped and we stopped hanging out. I think it started to bother him but he never said anything. This first experience opened up new doors for me and I had many more experiences with other guys that continue to this day more than 20 years later.
