When I was younger (about ages 12 to 14), one of my good friends and I use to JO together all the time. We made games out of it and everything. Back then though, we always finished ourselves.
He moved away, and for years we lost touch. One day about 4 or 5 years ago now, we reconnected through facebook, met up, and he stayed over that night at my place. Guess what happened. lol. We were actually watching a movie on TV together, when he said he wanted to watch some porn. I got out my laptop and told him to watch whatever he wanted on there. I was still watching the movie at first, but quickly started to pay more attention to the porn. He was rubbing it through his pants, and I started to as well. As time went by, he slid down his pants and was rubbing first through, and then inside his underwear. I followed suite. Soon I was watching him more than I was watching the porn. He whipped it out and so did I. We stroked ourselves for several minutes, until I finally asked him if I could do him. He said he was close, and by the way his cock was twitching, I knew he wasn't lying! I was kind of close myself though, too. So, I grabbed his cock, and almost immediately he grabbed mine. We rubbed each other out in less than five minutes. I started shooting literally about one second after he did, his hand still on me, mine still on him.
Since that night it's only happened once more. (He did spend a few years in the military between then and now though too). I was staying over at his house this time, and we had decided to watch porn on his laptop. We were sitting on his bed watching it together, each rubbing ourselves through and inside our underwear. After a while I just whipped it out and he followed suite. A few minutes later, he reached over to his laptop to pick out another video, and I just reached over and grabbed his dick in my hand and kept the stroking going for him. After he picked the next movie, his hand came over and kicked mine off of my own cock, and once again we were jacking each other off. About ten minutes later I shot off my load, and about 5 minutes after that I had worked his out of him.
Wish this kind of thing could happen more often, but once again he lives far from me. Have always enjoyed stoking with him, and often wish I had another friend like him who lived closer that we could do that together on a more regular basis.
