About 3 years ago I started fucking my friends wife. He asked me if I would like to do her. I couldn’t refuse as she is quite a babe. He had been working on her for ages and she had finally agreed to go along with him on it. She and I get on and we had joked and flirted for a while. What I didn’t know is that her flirting was real and as it turned out, she was doing it for him to see. When I said ok we all talked. She took over and explained how it was to happen. She said she wanted me to have sex with her and that he would be there watching but I was not to cum in her. She was on the pill as they didn’t want any more children and it wasn’t that she wanted to have protected sex or didn’t trust me but she felt that only a husband should cum in his wife. Her view was that if she followed those rules then she didn’t break her marriage beliefs. I was fine with that. I started to stay at their place at least once a week and sometimes twice. She always was up for more than one fuck too. The first few fucks I did it normal and just shot in the condom and then for variation I used to pull out and tear it off and cum on her stomach or back depending on the position. She suggested that I finish in her mouth which felt great for me and her husband really got off on that as well. I think it may have suggested doing that because she knew it would appeal to his fantasy. Something which was strange to me is that he hardly ever joined in. I only saw him fuck her a couple of times when I stayed over. But he used to tell me how they had a great fuck after I left. He said it was because I got her primed and wanting more. But from what I saw when he fucked her it was over fairly quick. She was always amazed how long I could last. I have had plenty of practice and good teachers so I can control when I cum. It was because of this I asked her could I fuck her bareback and pull out before I came. I promise to do it the same as wearing the condom and just cum on the outside of her body. She didn’t agee at first but eventually came round to letting me do it. He was very excited about and pushed her to do it. She was nervous the first time but it went well and we did it that way after with no problems. I never ever came in her and it obviously felt better without a condom. I am still fucking her and she never tires of me. Her husband is fine with it and I am not complaining. I do have a steady girlfriend now as well but I keep my 2 lives separate until I see how things go there.
