We've been friends since 16 years old
One Saturday back in the spring of 1987 I was sitting at my girlfriends house watching porn, since she had gone for the day. She had a pretty good collection of lesbian porn, since she was Bi herself.
About noon or so, my best friend D, I had run with for 20 years or so showed up to do some work on an old car I had in the girlfriends garage. We had been working on this old car for several weekends an evenings already.
Anyway, when he walked into the house, he seen that I watching porn, an got him a chair an sit beside me to watch for awhile before we started working on that old car.
After about 15 minutes I said to D that these lesbian movies are sure giving me a hard-on an he said, yeah, me too.
I ask him if he minded if I jacked off while we watched, and he said no problem. I told him that he might just as well do it too since I was. He unzipped and pulled his hard dick out of his pants and started to jackoff at the same time I was. I looked over and saw that his dick was a twin to mine except his had a dark bush, where mine is a light brown. Both of us is right at 6 3/4' long and circumsized.
After jacking for about 10 minutes I said let's go in the bedroom an take all of our clothes off and be more comfortable on the bed where there is more room. D happily agreed, and less than five minutes later we were both kicked back on the bed watching the porn on the bedroom TV.
I said hey D, why don't you jack mine an I'll do yours, be kind different to have a strange hand on each other. D thought that was a good idea and we slowly jacked each other off for about 15 or 20 minutes until we decided to switch ends and finish each other off up close where we could see each others dick when it cum. We ended up squirting all over each other and had a heck of a mess to clean up.
Haven't done that since, but sure wish we could get together and do it again sometime, last time I talked to him, he sounded like he was game for it the next time I am by his house when his girlfriend would be gone.
We tried some other stuff that day also, but that is another story for another time....
