I began having a sexual affair with a woman who was my coworker. She had recently broken up from a relationship with a man that was an attorney because she refused to have sex with him unless they were married. I was having lunch once per week with her and she was openly talking about it. Somehow, I stumbled on the right thing to say to encourage her to at least masturbate. She lived alone, but next door to her parents. I told her that they wouldn't see her get nude and touch herself. After a few weeks, she said she wanted to have sex with me, so we began meeting at a nearby hotel and she became sexually active at the age of 33.
