I (husband) have met three of them.
Two were met unknowingly of the fact at time, they were her cousins (well, they stiil are lol). Wife used to fool around pretty dirty with them in the past of very early days of sex discovery and I met the first one during a family reunion and the second in our own wedding party. I just didn't know anything about their fucking in the moment. Now I know.
Another one I met already knowing the guy used to play hard with my wife. He is a friend of hers who lives in her hometown. They reconnect and see each other from time to time, also.
