My wife

Hello B@W, I am happily married man. With what I believe is
the most wonderful woman on the planet. She means the world to me. We've been together for over 20 years , married for 10. She just amazing. We've had a wonderful sex life for sure. She very into me we've been very faithful to one another I'm the only man she's ever been with. I on the other hand have been around the block and back several times. I have a dark fantasy. For the last 9 years or so I gotten so turned on at the thought of sharing her with hung black men. I can't get it out of my mind. I can't even watch porn with out it being wives on bbc. Has anyone been through this? I don't believe my wife would ever be
On board but u never know? Do many of you married ladies think about sex outside of marriage with black men?
