Like many couples, we played the cuckold game. We invited bisexual men over to have sex with her; she would have me orally service him before they had sex, and clean both after sex. Quite often they did not give her an orgasm and after they left she and I had sex. In reality it was cuck play. Thirteen years ago she had her first black man on my business trip to NJ with her, and the dynamic changed dramatically. She had her first multiple squirting orgasm, and had so many she was dehydrated afyer a 5 hour sex marathon. This scene replayed itself for the next 3 nights. Even though she declared her pussy black only after the first night, when we got home I thought things would be back to normal, but in reality the real cuckold marriage had begun. Within a few days she needed more and I brought her back to NJ. Admittedly the first few months were scary. She changed significantly, more in-charge with me, and her sexual hunger at times was insatiable. But over time we actually got closer and she admitted how lucky she is to have a caring loving husband. Ironically I am the 'stud' of her friends. She tells them about her huge multiple squirting orgasms, and other then the limited few with whom she told the truth, the others think it is me. Even her best friend, who craves BBC, but married to a control freak, has told her that she wishes she was married to me. To quote her, "Your hubby gives you every desire."
My wife has come on to black men in public by flirting, or by flaunting her BBC anklet. But typically she does not care for that, too risky not knowing the guy.
