[m] theeesome with wife and sis in law [ff]

My wife and I are very open, we talk about what family members we would fuck. What friends we think like us ect. I had a feeling her sister would be down to fuck me. We heard her and her girlfriend playing next to us and got off to that previously

A few months prior we talked about a swingers club. One day she called my wife, sounded funny. We opened up FaceTime and she was getting her pussy eaten by a girl under the sheets while giving a guy head in a hotel room. She thought I left but I was jacking off to it
