It was obvious that she was unsuccessfully trying to bring her emotions under control. In between sobs she would push away from me a bit and try to sa... something only to have it choked off. It was all I could do to keep control of my own feelings.As things quieted down and we both gained some meager control of our emotions, I said, "I'm Joe. Would you at least tell me your name?"She lifted up for a moment, wiped her eyes and pulled away from me to sit on the steps. She looked at me and at last. The guilty conscience afterwards was already a bit less annoying than in the night before. Gradually I got used to the thought of fucking my granny.Within the next weeks my view on my granny changed. She gradually moved from being my grandma to being a women I was hard for. Being the object of my sexual desire. But I had no clue how to hit on her. But then I had the grand idea: I began lurking around at that one bar I once saw her. I checked in there every Friday. Not for the whole evening,. A second, longer, leash led from her nose ring to Aisha's hand. Not that she needed it, she would follow the slave girl willingly, but it added to her humiliation and discomfort.Her nose smarted with every step she took. She kept her hands as high as she could, straining her breasts to the maximum she could tolerate. That was the first of her quandaries. If she lowered her hands, relieving the pain in her breasts, the pain from her nose ring would be intolerable. She had to balance both. Even when they started comparing notes of the girls they claimed they banged over vacation. Cynthia was great, she let me fuck her and pretended to be my sister for me. But now I had actually boned Aida, my sister. Would it still be good with Cynthia. She was great that night right after my sister had ridden my pole hard. But I thought that was just her. I found myself beating off more then normal and most was thinking of Aida. My sister had jumped at going to school. She spent more and more.
