I have actively sought this lifestyle and have some experience too. I experience it when I saw my wife flirting with other men would excite me and I wanted to watch her being fucked by other well endowed men as well as women. She had a friend who was very rough looking and he was fucking her in hotels and sharing her with his or friends. She loved being treated like a total slut. It would excite me tremendously. Once , we were attending a party and she got drunk and I had to take her to a room to settle down.. she told me that she needed her friend to come. In and fuck her. I sent the guy up and he was in there fucking her for hours.
