I had posted in another thread that a few know. However, when Beth first went black only, it was on business trips to NJ and her black boyfriend liked openly express his control over my wife, and would tell people (cabbies, bartenders, waitresses, etc) that I am her cuckold. Some knew what it meant, for some he had to explain. A couple of times the women would say to my wife that they wished their hubby was obedient like me. It was both embarrassing but also strangely erotic too.
The most embarrassing time was in a Marriott lobby, a hotel which I frequented on business trips. Her boyfriend was taking a cab over to take us to a club near him. Beth and I had been sitting in the lobby for awhile, and it was pretty obvious we are husband and wife. When he arrived we walked over the greet him. He put his arms around her with his hands on her ass as he french-kissed her. I felt ever eye in the place focused on us. They walked out arm-in-arm as I held the door.
