We have been married 4 years, the second marriage for both of us. I have recently discovered some secret writings my wife wrote about a guy we both know through work. We attend symposiums around the country and he is at most of them with his company. My wife often attends these meetings without me. Her thoughts are very specific, very romantic and discuss her intense emotions. My wife was away when I discovered this. On her return I brought up the subject, I was angry, felt let down but, also excited. After a lot of discussions we realized that this just a fantasy of hers. I told her it made me horny. She then told me one of the few times she had watched porn and was turned on by it was when watching a husband share his wife. She also told me of another fantasy, being fucked by more than one guy. I have always been turned on by the thought of someone else’s cock fucking her, pre this, so we decided that a couple of times a month we would take turns in exploring fantasies. She has told me she doesn’t actually want to fuck anyone else but I would really like that to happen. How do I take this bit by bit to the next stage? PS I’m aware of and have considered the potential problems.
