Love seeing my wife flirt with black men

My wife and I have been married for 27 years. Two years ago we agree'd to an open relationship. However, the agreement was she could only fuck around with black guys because I new if she got emotionally attached I wouldn't have to worry about her second guessing our marrage and leaving me for another white dude. Reason is her family would disown her. How do we know that. She had a black boy friend in high school and things at home got really bad between her parents, brother and sister. Now she is back with her high school boy friend as a fuck partner and yes it's a good story. Sometime I'll take the time to tell it!
