I am fifty-five and have been divorced for almost ten years now. My son, who is thirty-four, is also divorced. Over the last few years the two of us had started to become pretty good friends as mother and son. We live in the same town and often see each other. About a year ago, he came over to my house one afternoon, and I had had just taken a shower and was just in my robe when I answered the door. Of course my son was not expecting this, and he commented on how he thought that he had an attractive mother. Well, that was a nice compliment, naturally. I said something back about how nice it was to hear complimnets like that, and he remarked about how even if it was from my own son. I replied how I didn't necessary mind that. And I guess that I was feeling in a playful mood, because I teased him and said how of course I didn't know how he would feel about having some fun in the afternoon with his mother. He laughed, and said how that would be fine with him, if I felt like it. It was daring and we both found the idea not unappealing. After teasing each other about fooling around, we went into my bedroom, and I slipped off my robe, and he got undressed, and we stretched out on the bed for some caressing and petting. He got the most wonderful large erection I can tell you, which thrilled me. In no time at all, we were busy having sex and delighting in every heavy breathing moment of it. I had a fabulous orgasm, and thankfully we did not have to worry about birth control, so he went all the way with me. It was so wonderful! After that time, my son and I have been having a marvelous sexual relationship! No, no one knows, of course. Yet, for the two of us this has been the most satisfying and agreeable arrangement.
