This caused us a real problem. For a period early in our marriage, we were open sexually. We were swinging some, mostly she was bringing her girlfriends into our bedroom. One woman actually lived in our house with us for the summer following a divorce. The reason for the divorce was her desire to become pregnant, and her older husband did not want to go into his golden years going to soccer practice. A summer of threesome fun began and every time I had sex with my wife, her friend would go down on both us and clean us off. After a while, my wife wanted to do this, but she didn't explain to her friend ahead of time what was going on. She simply to me to cum in her pussy. The moment that woman felt me cum inside her pussy, everything we were doing changed. The way she looked at me. After the sex, she began kissing me. I had pulled out every time before. By the time my wife licked it off, it was too late. We had a woman in our bedroom actually asserting herself between us. That led to some tense talk, and she ended up leaving which was pretty sad because I actually did like having her around.
