What a wonderful site this is!
When I was thirteen I went camping with my folks. We brought my cousin John with us who was fourteen. The first night there it was very hot and humid so we decided to take a swim after my parents were asleep. John suggested we go skinny dipping. I reluctantly agreed as I was always shy about being naked around people.
Once we were in the water John started rough housing with me, dunking each other and wrestling. I remember at some point I got really aroused and he must have too because I felt his hard cock brushing against me. John dared me to walk back to the tent naked, which I did and so did he. When we got in the tent I started to put my shorts on but John told me to wait. He asked me if I wanted to jerk off with him. I told him I wasn't sure. He assured me it would be okay so I agreed.
We sat face side by side on the sleeping bags and started to stroke our hard young cocks. Then John reached over and put his hand around my swollen dick and took my hand and put it on his. Oh my God, it was the hottest thing I had ever experienced.(I was still a virgin then.) His cock felt so good in my hands. We stroked each other furiously until we both came at the same time and shot all over each others hand. We spent the next two nights enjoying each others cocks. John was killed in a car accident that same summer, but I will never forget that weekend that my cousin opened up a whole new world for me. I miss him still.
