Knowing In Advance Made Me Very Horny

I'm happily married, but my wife doesn't 'put out' any more just like your wife [jstfrths]. I understand this is common at our age. I have a friend I jerk off with all the time. She knows, and although she's not entirely fine with it, she puts up with the situation. I think she's also secretly relieved that he eliminates my sexual tension, letting her off the hook. I went to see my buddy. We have experimented together many times. Mostly, he comes up with good ideas, and I enjoy being his guinea pig. We meet at his place typically once or twice a month. When I got there, we stripped without fanfare, as we have done many times before. He invited me to go first onto the sheet covered mattress he had put on the floor. He told me that this time, he was going to make me cum, and when I came, he would squeeze the tip of my penis closed, blocking the ejaculation. In the days before our meeting, I had become terribly aroused just thinking about it. And a bit frightened too, I was assuming it was OK. It wasn't going to kill me. I mean, if it was a bad idea, there'd be dead guys all over the world, because I'm sure guys have experimented with this sort of thing before. Still, it scared me, and I do believe that was a major part of the horniness. So, he started with a gentle handjob, slowly working me toward orgasm. Then I couldn't hold off, and I started contracting, and true to his word, he squeezed the tip of my penis closed with his thumb and the side of his first finger. I was so scared I begged him to let go. But he ignored me, holding my penis closed during the entire orgasm. Interestingly, the contractions lasted twice as long as normal. My body tried really hard to force the cum out, but it wasn't happening. It hurt a little bit, but not very much at all, really. I immediately knew this wouldn't be the last time I'd like to play with this new experience. As my orgasm finally subsided and my dick started to soften, he continued to hold my penis pinched closed. He asked whether I'd like the cum forced back and into my bladder. Oh my god, just the thought of it caused my penis to harden up again. And this was right after an orgasm! And, I was also scared again. Would something in me burst? I guessed if it hadn't already, I'd be alright. I said 'Yes', but with a little reluctance. The cum trapped in my urethra was starting to itch a bit, something else I've never experienced. I'm guessing it is a bit alkaline, to nutralize the acidic urine, but that the urethra doesn't want long-term exposure to it. Still holding the tip, he started pushing his finger tips into my urethra, working slowly to the base of my dick. He was pushing a little hard for my taste, but it also felt very interesting. As he worked farther down, he removed his fingers from the squeezed tip of my penis. Nothing came out. Now, he used both hands working down toward the base. Finally, he was pushing on the area between my balls and my anus, when suddenly I felt a sort of 'blurb, blurb' as the cum started flowing backward through my sphincters into my bladder. I couldn't wait to pee to see what would happen. Now, it was his turn, and I gave him a nice, long handjob, focusing on that continuing orgasm thing you've been preaching [see some other Solotouch articles on that technique]. We've been able to accomplish it on occasion. With him, on this evening, I was able to bring him to several dry orgasms, complete with contractions, but I wouldn't say we got to genuine continuous orgasm. Anyway, after a while, he fully ejaculated. After staying with him a minute while he recovered, I excused myself to go pee. He followed me into his bathroom, wanting to watch, which in itself made me want to have another orgasm. There's something about being watched while naked and doing something sort of vulnerable... Anyway, about 3/4 of the way through urinating, I suddenly felt a sort of 'chunk, chunk, chunk' feeling as globs of cum flew out with my urine. Very cool! I can't wait to see what he comes up with next!
