I was a little shy of six inches and mine was really skinny back then.
We held them together and he was noticeably larger and his turned down a little, while mine turned up. I was very impressed with it and told him so. It had gotten so much bigger, bigger than mine by two inches and really thick. After a while I felt guilty about no touching him so I reached over, he immediately dropped his pants and I could see his cock. His hand came over and went at my crotch and when I didn't stop him he went for my zipper and had my jeans down in a minute. I knew where he was going and didn't really want to but was a little drunk and horny. We parked in a secluded spot and were drinking beer when his questions about sex with girls started.
We were alone for some reason and drinking, I think another friend was with us and someone drove by and he got in the car with them. At 15 I had a girlfriend I was fooling around with and I stopped with him until 17-18. We must have done it 30 times that summer, we did it ever time we could be alone. I wanted to stop doing it with him but didn't. I never felt anything like that before, I had jerked off but this was different. He started shooting on to me and immediately used his semen on me and I started coming. I told him and he just responded that he he was going to "shoot off" as we said back then. We were rubbing them together and looking down watching was putting me very close. We laid on our sides then face to face and teased away on one another. He suggested we try and come at the same time. We would stop the other when we got to close to coming. We were up there for more than an hour, we had no idea that we were edging each other, it came natural. I finally gave in and reached over and played with his. We quickly had our pants and underwear down and he was playing with mine and I was looking at his. I had been thinking all day how good it felt and how wrong it was, the good won out. The next day he asked me up to his room and it all unfolded. As I rolled away from my friend he let go. I'll never forget how it felt answering him while my other friend had a hold of my dick. As I really started getting excited our host woke and rolled looking at us asking if we were still watching the show. His hand went down and his touch was driving me crazy, he had gripped my cock and was stroking it. Last I remember is him saying it will feel better if I go in your underwear. He immediately remarked that I must like that and all I said was it feels good. I was getting hard and didn't know what to do, I just froze as he slid up and began feeling my dick and balls. He didn't stop and he was now inches away from my crotch. He rubbed my thigh a little and in a whisper asked if he was doing right. I was under a blanket and he had his hand under there. He pit his hand on my thigh and asked if that was how you started, I was wearing briefs.
The host had dozed off in front of the tv and my friend started asking about feeling a girl up. We had been talking about sex all day and how we had felt up girls and fingered them. We had a few beers and we're watching tv. We were 12-13 and at a sleep over, he and I at another guys house.
