First of all, I feel the need to let you know a couple things
1. My writing skills are that of a ninth grader, a pretty good ninth grader.
2. My friend Mike and I are both hetrosexual males, very horny hetrosexual, but hetro none the less.
My friend and I have known each other since middle school (we are both in our middle thirties now) and have always been great friends that have a lot in common, but not so much that we irritate each other (you know what I mean). We always talked pretty frankly about our sex lives but not too much about masturbation, just about our girlfriends, friends, and now...wives.
I think it all started thanks to instant messenger, we both work at companies where we sit in front of computers for most if not all of the day and we talk it up quite a bit, as anyone who has talked to someone on instant messenger knows, you tend to get a little more open when you aren't face to face with the person you are talking to.
His girlfriend Sara was getting more open about her sexuality and letting him take pictures and he would let me see them, plus his computer was having problems and I would come over a lot of days and lunch and work on it then we would surf porn (we both work close to his house) and talk about there newest adventures on the semi- swinger scene.
Anybody who has ever watched porn with anyone else knows how hard it is(pun)to keep your hands off yourself, and how you wish you didn't have to. Well, that day came one afternoon when we were looking at pics of his girlfriend posing in lingerie and he said 'How fucking hot is that' and I said 'I think I need to go and use your bathroom to take care of it.' and he said, 'You can do it right here, I would be right with you'. So I nervously pulled out my cock and started slowly pumping while we sat in chairs next to each other and looked at pics and video clips. He pulled his out a couple minutes later and we assured each other that it was no big deal, but also tried to take a look at the way we were both stroking ourselves whenever we could, this didn't last too long because of the pics and sexual tension in the air, and we both came within seconds of each other.
We now try to get together at least once a week for lunch and porn, but this is just how it started, there are more great MM stories to share but I'll save them in part two (maybe in a few days when I feel literate again)
