The second time my wife and I had a 3 some with a hung guy (8 x 6), I decided I did not like it. She went fucking crazy and, though my fantasy about it was hot, the reality did not get me a hard-on because I could not believe my wifes intense reaction. And I was also shocked how long they fucked. So you can imagine the scene with me and my small limp dick hovering about and getting her oil to lube up more and him right there with a huge dick pounding away. At one point he looked up and offered her to me but I was unable to fuck. He had to leave early so they would have gone on for more I am sure. He was a nice man, 45 yo, and we were in our early 20s, and he was not even good looking at all -short, glasses, nothing special. So I told her I did not want to do this anymore, and she seemed a little pissed and said I cant turn her on and off to sex with another guy. About 2 months later, we are screwing and I stopped and said that she appeared totally uninterested and unexcited. She then told me that she had been seeing Tom on the side since the last get together. I asked why like I did not know. She said he does not kiss well, and does not orally please her well either. I was much better at both of these things. The only reason she saw him was the fucking, which she said was incredible! I asked how many time they did it meaning how many times did they get together. She paused, thought about it and said about 21 or 22 times! Incredulous, I asked how did she get away so much without me knowing! She said they only met on about 7 occasions but he sometimes fucked her 3 or 4 times (and came) each time they met ! She described him as a sexual superman. always got very, very hard right away and could do it again really soon. He said it was only with her that he was able to do this as she was a very beautiful woman which she as and still is. The only saving grace was that his wife found out about it and they had to stop. Needless to say we broke up for about 6 weeks. We got back together but I have frequently used a dildo to finish her off ever since. We did go on to take up swinging much later in life, but that that is another story. Anyone here have a similar experience?
