My wife and I have been happily married for sixteen years. About four years ago, my wife and I started talking about spicing up our sex life. One idea we had was for each of us to have other sex partners. While the idea was exciting to me, I could not bring myself to let her go alone with guys I didn't know. My concern is for her safety. So, I asked her if she was interested in any of my friends. I knew before I asked which one she would pick. She told me that she had always liked my best friend Marty. They have always gotten along very well together. They always flirt with each other, and always give each other hello and goodbye kisses on the lips. I always liked that, too. So, I talked to him about it, and he said that he would jump at the chance to have sex with her. One night, we all went out to the casino. I let them hang out together while I went my own way. Later, my wife found me and told me that they were going to go get a room at the casino hotel. I was more turned on right then than I have ever been in my life. I told her that I would go on home and Marty could bring her home the next morning. When she got home, she told me the whole story. Then we went and made love for hours. She still meets up with him every now and then.
