I had talked to my wife for ages about swinging, all with no luck, but she was always into the idea when we were having sex. A few years later on holiday in Florida we met a guy who ran the local picture gallery, he took a shine to her and I finally convinced her to fuck him. Holiday fever and excitement took over and She agreed but I couldn't watch. This was half way through our time there. She told me all about it and she knew how excited it made me when she recounted the sex with him.
After a lot a discussion she agreed to fuck him whilst I watched. I spoke to the guy explaining the situation and he also agreed provided I just watched, which was more than fine by me.
I still remember that for me special moment. I was so nervous, almost shaking. I sat in a chair in our hotel room a little to the side, she didn't want eye contact with me she said.
When the moment came and she spread her legs and he moved above her between them although I couldn't see the actual moment of penetation, when he pushed forward she raised her hips and gasped, and held his hips with both hands, I knew he was then in her. He stayed still for some time before starting. I almost came in my trousers. I looked at her face she had her eyes closed but I could see in her expression what she had just experienced. I just could not believe what I was seeing, to me it was the greatest sexual charge I had ever had. He was very good with her, aware that she and also me were so very nervous.
It was the most exciting pit of stomach churning feeling I have ever had.
Since that time I have watched her with many men it always turns me on, but never like that very first time.
