    exhausted ourselves Sunday afternoon. I had paid little attention to her small nipples during our first session, but that afternoon I started to discover just how sensitive they were. Gently sucking on them while I didiled her pussy with my fingers, brought her to the edge in minutes, so I had to back off to prolong the session. After she played with my cock for a few minutes, I explored her cunt with my tongue while gently twisting her nipples like the dial on a radio. She loved that too. After over an hour, she said that she couldn't wait any longer, and that we had to finish. That time, she straddled me, in what would become her favorite position, and we orgasmed together. I saw the strain in her face, as she struggled to cum, but I saw the pure love and concern in her eyes too. We did it again on Tuesday, and Thursday. Mom told me that she was so happy to have stayed on the pill. She'd never used birth control with Dad, because they had always hoped for a second child. Once Dad was gone she had gone on the pill thinking that she would be getting a lot of "swinging single" sex. It hadn't happened. She'd had just 2 one night stands, where the guys didn't call. She had been about to stop taking her pills, when she started up with me. On Friday, I was looking forward to Saturday. At supper on Friday, Mom said, "Let me tell you about Aunt Sue". What was to know? I saw Aunt Sue, and her daughter Kassie, at least twice a month, and I knew that Mom and Auntie talked on the ...

Sue and the baby had lived with us for 3 years. Dad had not been as willing as I may have thought. Mom had told Dad that as long as Sue could live in the house, he would get to have sex with one, or the other, every night, or if he wasn't willing, he would get almost no sex at all. In the end, he agreed, and Mom said that he had been a very considerate lover, "Just as you are". She said that on her nights, he was always as enthusiastic as if he had not been laid for a week. Auntie gave him great marks too, and Dad and Sue continued to have occasional sex, even after Sue moved out. He had been Sue's only constant, between a series of shitty boyfriends, and when Dad moved out of town, Aunt Sue missed the sex as much as Mom did. "The bottom line, Will, is that if you are willing, I'd like to share you with Aunt Sue. She needs a lover, and I know that I can't keep up with you for long!" I asked when we would start, and she said,"She will be here at 7." After a few minutes of hellos and small talk, Sue said that in order to hide our affair from Kassie, she would only stay an hour, and then go home, "So we need to get started!", she laughed. Mom said that she had some shopping to do, and left. Sue was younger than Mom, but they looked a lot alike, except that Mom dyed her hair a different color than Sue did. I thought that Sue ...
