My Young Friend Came Twice

The boy was a friend of mine. He had been talking sex all the time, so I knew what I had to do for his 18th birthday. He was getting a handjob! I was a little reluctant to bring it up, but when I did, he was unabashedly delighted. I jerked him off, and he loved it. Over the next few weeks, we repeated the process several times. Sometimes I'd go first. He'd have me lay on the bed while he sat next to me, or straddled my legs, and wanked me gloriously. Sometimes, he would go first. The version we were both loving is that one guy gets all the attention while the other guy does the 'work.' Then we'd switch. Somehow, and I don't know why, we were very compatible in that neither of us wanted blowjobs, anal sex, or anything like that. Not even kissing. We were just interested in these handjobs. Doing him never felt like work to me. In fact, I was always disappointed that he came too quickly. I mentioned this to him, and to my surprise, he told me there was a part of it he didn't like either. He wasn't done when he ejaculated. I had no idea! Once I cum, I'm very done. Just touching my cock to clean up is excruciating because it has become so sensitive. So, the very next time, as he was ejaculating in my hand, I just kept going as if nothing had happened. He squirmed and moaned a bit for the first minute, but I kept going. The cum was turning into froth piling up in the area between my thumb and first finger. It became like whipped cream. I never realized it would do that. Soon he was going 'Mmmmm,' and arching his back. He ejaculated again. I tried for a third time, but no, he was finished. It took us a year of practice and experimentation, but we finally figured out how to do this to me. He'd give me an excellent handjob. I'd cum. Then, he would continue, but very, very lightly, using only short, slow strokes. That, I could stand. Anything more would have had me pulling away and yelling for him to stop. It took a good few minutes. I didn't go soft, and in fact, although the touching was very light at that point, it was pleasurable. When he saw me settling down, he increased the length, pressure and speed of his strokes, and sure enough, I came again. To this day, we get together every week or two and practice our techniques while our wives go shopping or whatever they do. I'd like to think that they play with their own version of mutual masturbation, but unfortunately, I don't think that's the case. He and I are trying to accomplish cumming three times in a row.
