My first mutual buddy was when we were both ten and discovered masturbation...and well, just kept discovering new things to do!
In college, my roommate had a sailboat, and on warm nights liked to go out and sail--and jack off together. When I transfered schools and lived in a dorm, I began talking about masturbation with guys here and there, and then one of them wanted to do it together. So we did, and then did it again, and again!
Then I had a gf who used to like to go over to this guy's apartment, and they would kind of spar with sexual innuendos--he was always trying to fuck her. He was very dominant and VERY persuasive. She finally admitted to me that she had sucked him off a few times, and I thought that was really hot. She told me that she'd sucked him the other day, when I was away. She asked if I was angry, and I said, no, I really could see how she would want to, and it was really hot, thinking of her sucking him.
Well, a week or so later we were over at his place, and he started on her again, and this time she wasn't going to pretend that she didn't want to. He tried to get her to take off her top, and she resisted a little, and then flopped out her tits. In a flash his cock was out and ready for her. I watched as she began sucking him--she was totally hot and turned on. He told me to jack off if I wanted to, and so I did. We went home and fucked like crazy!
Well, that was the first time, but the story didn't end there. Without thinking about it, one afternoon I found myself at his place alone. He talked and kidded and stuff, and then out of the blue, he asked if I wanted to jack off with him. We both got out pants off and were wankin pretty hard when he said, "You wanna suck me?"
Instinctively, I said no, but he saw through that. "Hell you don't!" He stood up and stuck his cock in my face. I took it and began sucking, nervous and confused--and totally hot. I have no idea what kind of bj I gave him, but he did cum pretty hard.
I tried to get him to say he wouldn't tell Sharon, but I knew he wood (he was a nasty bastard!) Then I realized I wanted her to know. When I left, I decided I would tell her--some time. Well, I got home and the bastard had already called her to tell her that I'd just swallowed a load of his cum. She was flushed and crazy when I walked in, and in a moment landed a long French kiss on me. Then she told me. And kissed me again. And told me it made her very hot to think that my lips had been around his cock, and she could taste him. Well, another really hot fuck lasting hours!
We decided to both go over the next day, or whenever we could, and then on the way she told me she wanted to fuck him in front of me. Oh shit! I felt sick all the way there, until we got to his door. Then this huge wave of heat came over me, I'd never felt so hot before in my life. He took us to his bedroom and told us to strip. She'd already arranged that he could fuck her, and was hot and eager to do whatever she said. I hadn't talked to him since I'd sucked him, and didn't know what to say. It didn't matter. She was quickly on the bed and his cock was in her, doggy style. He fucked her crazy and I jacked off like never before!
We went over there several times before end of the year, when she moved away. The next year, I would go over every week or so by myself, and after the second or third time, he got into masturbating and sucking me, too.
