My wife has been fucking a coworker of hers. They work for the same company but in different cities. Whenever they travel together they have sex and send me pics. It began with them cheating, I found out but they never stopped. He's coming to town soon for work and is going to stay with us. They've already decided I have to watch. I'm a little nervous about it. Not sure how I'll feel. Any advice on what to expect?
