I had separated from my wife and on the way to divorce. A friend allowed me to stay at his place for a while. This guy had a girl Diane living with him, plus he was out screwing other females in the neighborhood. And on weekends he went to see some girl who lived 30 miles away. So one weekend while he was gone Diane told me she asked him for a committment, but he rejected that. So she decided to move out and asked me to help. We moved her stuff into her mother's apartment, then she said she needed to go back to make sure she got everything. When we went back, she said she wanted sex and said her girlfriend Debbie (who I fucked before I was married) told her I was good at eating pussy.
I knew this request for sex was to get revenge on the guy, but it didn't matter as I had always wanted to fuck her.
We went to bed in the bedroom she had shared with him. After sucking and fucking for a whle, I took her home. When the guy returned he was not fazed at all that she moved out, as he still had all those other females to fuck. But I don't think he ever knew I had started fucking Diane.
