Beginnings; Mark

This is a part of my behinds series about all my early sexual encounters. Although they are mostly women I did have a M4M encounter in my teens as well. I was 16 he was 15. Mark and I were friends who hung out all the time and we were never into each other, but one summer we hung out a lot, and on one particular day we took it to the bedroom. Before this day we had played with each other’s cocks, giving each other hand jobs and what not. We progressed to blow jobs when we went on hikes together. It was super hot to step off the path and pull each other’s cocks out and take turns sucking each other’s dicks. Even though Mark was younger than me his dick was bigger and thicker. He was always very clean and did not have much public hair. When we were in his bedroom we would spend a long time sucking each other off. Kissing, and licking and sucking cock for a long time. I preferred going down on him than him on me. So back to this one day in particular. We were alone in the house and we were hanging out playing video games while the other goes down on them. We decided to get naked and jump under the covers. I was about to go down on him again when he asked if I could top him. I was shocked but said okay. He got on all fours and pulled his cheek back and helped me guide my dick into his as. It was slow going at first. I told him to relax and after a few attempts I got my dick in all the way. It felt good to me and I asked him did it feel good for him. He said it’s weird, but told me not to stop moving back and forth. I continued to slide my dick back forth as he got used to to it, and then at some point I could feel him relax completely and it allowed my cock to go deeper, and then I started to speed up and go harder. He was now moaning as I I held onto his waist while I continued to thrust my dick in him. He started to jerk off as I banged him. I told him I want to cum. He pleaded for me to hold on until he did. I held in there and we came together. Me in him and he all over his bed. We collapsed on your backs, our socks throbbing and drained. We took a shower together and had a wonderful time of making out and dick swallowing. And the whole summer was what I labeled my bi-summer. Fucking girls and my friend all the time.
