My wife and I both got into the cuckolding lifestyle after I found out she had cheated on me. Our sex was amazing after she told me about it, and after extensive fantasizing for a year and a half that she was for the most part initiating, we finally brought in a 3rd person and I watched and then participated. I have never seen her cum so hard or so many times. She was like a wild animal. and everything went great. Suddenly about a week after that experience she then shut down almost completely. It is just straight missionary sex. she doesn't want to discuss or talk about anything kinky anymore. there has been a 180 degree turn around. At first I thought maybe she was stepping out but that was more than a year ago and i've found no proof of that. please help me interpret this reaction.
