I'm 18 now, but this story happened 5 years ago. My friend from school was coming to stay over at my house for the first time. We did the normal sleepover things, video games, tv, movies, etc. Then we decided to get changed and go to bed. I stripped down in front of him, not thinking anything of it. But then I noticed that he was covering his crotch for some reason. He had a boner! He was really embaressed. But I said I didn't mind, and in fact, it gave me one too! I suggested we compare and that seem to make him more comfortable. He took his out and we kind of looked each other over. Then I reached out and grabbed his dick. He was kind of suprised, but he went with it. He grabbed mine then and we started jacking. It felt great. I leaned over and put his somewhat small cock in my mouth and started sucking. We laid down and he started sucking mine too in a 69 position. It felt great. We finished in eachothers mouths then went to bed. We never really talked about it ever again.
