He saw Corven's face twist, "Sadly, she will only accept a man that she has never met before, and after that night, will never see again. No matter wh...t happens. She should be loved by somebody on a permanent basis, but sadly with this perversity in her nature, this cannot happen. She is my sister, and I'd give anything to see her happy. Her demands are not daily" He paused as he stopped for a red light. "Quite acceptable demands. Maybe once a week, maybe a fortnight. She is no nympho."Harry. He said his friend was John and sent us pictures of him in cycling gear. John was in his mid fifties and like David was married but unlike Mike and I, had a stagnant sex life. Our sex life is amazing and I never have to go short, either with Mike or one of our many friends. Anyway the day of David and John's visit arrived. I was really excited and put on a fairly loose skirt, easy access, stockings and suspenders and matching bra and panties. Mike and David had worked it out earlier that it was. I’m not sure what came over me, but maybe it was the way you two assholes have been teasing me about my small dick and your big cocks, and I just had to have a feel of it. Is that what you were hoping for when you pressed your cock against my ass?”He answered, “No, it was an accident when I first pushed against you, and I didn’t think anything about it since you didn’t say anything or move away. But then you reached back to feel my cock, and I knew that I had to see how far you were willing to. I was curious to develop sexuality and when I saw in videos and magazines a lot written about BDSM. I was curious to try. Then one day I saw an advertisement from a dominant woman in a common sex magazine, where she looked for a slave for a long term relation. i contacted her and to my surprise she invited me to her home. I learned later that her husband was also a Sub of her, but that doesn’t matter as all dates with her were without him. Then we had a first date. I visited her and she did.
