This happened when I was 13 over summer
Me and my friend-who i'll call John-were riding bikes and hanging out all summer. We had been best friends for about a year and we were really horny kids. We would give each other sack whacks and wrestle in the middle of video games. We had only seen each others naked from behind, when we would change to swim, but we both were curious.
One time during summer, I spent the night at his house, we were in his room in the far wing of his house. We were playing video games on our stomach in his bed and while we were waiting for it to load, I took my shirt off because it was so hot. The summer heat is crazy where I'm from. John took his off too and then he locked the already closed door. I thought this was strange and I asked him what he was doing. He said that he didn't want anyone bothering us in the middle of the night. It made sense. We wrestled over his winning at halo and then we both kinda started pulling each others shorts off. We were down to our boxers and then we got naked.
John turned out the lights so it was black and we talked about sex and hot girls. We got into his bed and covered ourselves with the lightest sheet. We talked about cumming and we argued over who could do it faster. He wanted to look closer at my weiner and told me about a game where two friends lay on their sides next to each other with their heads at opposite ends to see who can cum the fastest. The loser has to eat it from their face. So we went for it. We spat in our hands and jacked each other. John jizzed first and he won. His jizz went all over my face and I tasted it as he jacked me. Shortly after my tight balls exploded and he ate it too, for fun. We did this all summer every weekend till we got to high school. We still screw around now, but we don't jack anymore. It was a lot of fun back then, and we both turned out straight. We have girlfriends and we still hang out.
