I had this best friend growing up that I’ll call J for this post. J was always the guy in the friend group talking the most about sex. Always talking about girls, his dick and getting laid. We had been best friends since 4th grade. One Friday night with not much going on our senior year in high school we went to the local gas station and bought a few porno magazines. We were in my room flipping through them talking about the girls etc. I had twin beds a few feet apart. We each grabbed a porno and stripped to our boxers and got into our own bed. Turned off all the lights except the bedside lamps. . We kept talking about the girls and what we would do if we had the opportunity. I was hard and it was obvious J was hard as well as we both casually stroked ourselves under the covers. I mentioned how I was getting hot and took off my boxers and threw off the comforter. I now only had the sheet on my naked body. My hard cock noticeable through the sheet. I saw him look over more at me slowly rubbing myself than looking at his own magazine. That got me even more hard. I liked showing off. I shoved my porn mag under the bed and told J I was tired and was going to sleep. He said he was going to stay up a bit longer. I feigned going to sleep for probably like only 2 minutes then tossed and turned a bit so the sheet conveniently slid off to side and exposed my raging hard dick. Through my squinted eyes I saw J take notice and start actively stroking himself under his sheets. I didn’t know where this was going. All I knew was I was really turned on. I payed there and squeezed my ass cheeks together a few times to make my cock bounce off my chest. J must have liked that as he took off his covers and slid his boxers off and started slowly stroking himself while watching me. I bounced my hard cock a few more times. Watched him stroke a bit faster. He couldn’t take it any longer and came over to my bed. J straddled my legs and started furiously stroking me. It didn’t take me long. I shot a huge rope. Some of it hitting the headboard behind me. Some on my face and on my chest. When I was done he went back to his bed and started masturbating. I was covered in cum so I got up and got a towel. I got back just in time to watch him orgasm and shoot a load on his stomach. I went and got J a towel. We both looked at each other and just nodded. We never really spoke about it but continued similar behavior for years afterwards. J will still ask for pictures of my hard cock on occasion to stroke to.
