This happened when I was 12 in seventh grade. Me and my friend Chris got to know each other in sixth grade. In seventh we had 3 classes together, and we became close friends. He invited me over to his house one night. We played video games and his mom went out for groceries, with no one in the house he pulled out his dads playboy mags. We talked about girls and looked at the magazines while we both noticed each others little weiners sticking up.
His mom came home and his dad got home from work, we ate dinner and went to his room for bed. We went in to his room, and he said, we can change into our pajamas now. We both kind of hesitated and we stripped naked. We put our pajamas on over our briefs, and I unrollled my sleeping bag on the floor. He said, don't you want to sleep on the bed? the floor isn't comfortable. I said 'yeah, sure'. So I put my sleeping bag on the bed. We locked the door and both hopped in.
We played video games until we got bored, and we started wrestling in his bed. We were pulling on each others balls, and I skimmed his crotch and his penis was hard. I was hard too, and we both slid under the covers. He slid his hand down and grabbed his penis. I said 'how big is yours? and he said 'if you show me I'll show you?. We put the topsheet over our heads and used a flash light to see, we slid our briefs off and looked at each others. Then Chris touched my penis, and I flinched and then touched his. We were both sticking straight up, then he leaned over and put his hand on my penis, and said do the same, and we played with each others balls and little four inch dicks until we had a dry orgasm. It was great. The next day when his parents went to work, we took a shower together and touched each other too. It was something I won't forget, even though we were both straight.
