My cousin and I were always very close, talking openly about masturbation and things like that. That day we were having a garage sale and my dad had this huge closet, so I had never gone through his things, looking for items to sell. After a little while my cousin shouted, 'Hey, look what I found,' and he quickly grabbed two Playboy magazines. I did not say anything because I was afraid dad could hear us. I told him to take them outside and that we'd look at them later.
Later that day he told me he wanted to look at the magazines and obviously I did too, so I agreed and we started. We both quickly got a hard-on and he said he had to go to my room to jack off, because he was way too horny to keep looking and not do anything. He left and said he'd take one of the magazines with him. I told him it was ok. I had never masturbated before because I was very religious, but I was very curious and headed for my room. There he was, jacking off. I stood and did not say anything, but then he looked at me and said that he'd teach me how to do it. At first I refused because of what I said earlier.
He continued jacking off and seeing how much he was enjoying it I finally told him to teach me. He started by telling me to take off my pants and my underwear, so I did. He started to stoke his dick and told me to do the same thing. By now my cock was as hard as a rock, but all this was very new to me, so I was a bit confused and did not know if I was doing it correctly.
He told me to relax and that he'd do it for me if I did not know how to. I let him do it and after a few minutes I came. It was the greatest feeling I had ever felt. He told me to do what he did back to him and I accepted. He said I was doing very good and after eight or ten minutes he came on my hand. After all, we did not even need the magazines.
Ever since this happened my cousin and I have never done anything like that and we've never talked about it.
