When I ran into Stacy at a coffee shop, I had been broken-up with her older sister, Nora, for six months. She asked me what had happened and I told her that I'd suggested adding another guy for a threesome and she walked out ending it. "That's just like her," she said, "but I like the idea. Let me talk it over with Tom and I'll let you know." Well, I wasn't sure exactly what she meant until her husband invited me over that weekend for burgers and sex with his wife; oh, was she different from her sister. She already had a husband but I became her lover, her open lover, as Tom and I took care of her the way she wanted.
