Exposing my wife experiences

Last year, I exposed Pam to a guy with a great imagination. He was into being a dom over a housewife while the husband watches and maybe helps. I emphasized that I was not a cuck, but what is called a "stag", or a dom husband that shares a sub wife with another dom. He wrote some great scenarios and we corresponded for a couple of weeks. He hinted at maybe trying to get together with us for a threesome, but I had to create some limits and make sure he knew this was only fantasy play. Once he understood that, he came up with a relatively safe way to see Pam in person. He happened to be a musician in a popular local band in town, and he invited us to his concert one weekend. I could pretend that I was a friend and introduce him during a break to Pam. That way he could see the woman he had already seen posing in lewd, erotic photos. I took a risk, but went ahead and introduced him to Pam. He was thrilled and talked about the thrill of talking to a mature woman who hadn't a clue that he had seen her fully nude, playing with herself, and on her knees sucking a cock. That was fun, and when he starts playing again, we will go back.
