I had been in a confusing incestuous threeway for almost a year. It started one night when my sister crawled into my bed and gained steam three months...later when my mother caught me in her closet taping her being gangbanged by four men while my father was out of town on business. Sis knew about mom, but mom never knew about Sis. Between the two of them I was getting more pussy than I could handle. In fact I was getting so much pussy that I never ever bothered to get a girl friend. I was virgin. After a little while of first meeting her i had started to hear some strories about her mother from guys in work that she was kind of tomboyish she liked to drink pints watch rugby and was kind of one of the boys . A story that did stick out to me was that she sucked a couple of guys cock up the back of a bus on the way home from a rugby match and this just made me fancy her mum even more knowing that she was as big a slut as her daughter. One night when i was staying over i heard her mother. It was especially nice to follow Susan and Karen which didn't help lower my erection in the least.Dennis and his mom and dad dove directly in the water and started swimming around as Karen went over to lay down on a chaise lounge. I went to lay down too and get some sun.I raised my leg up, shielding my erection from the view of those in the pool as Karen said, "You might want to take care of that while they're swimming in the pool. I don't mind watching, Dennis and my dad do it all the time. She stood before the full length mirror. She was tanned and latin looking. With long curly brown hair and even longer legs. She wasnt skinny but she was by no means fat either. Just curvy in the right places. Since she had given birth, a year ago, men paid particular attention to her breasts as they had gone from a 36c to a 40dd and were often swollen with Milk. Her husband, Michael, considered himself a lucky man (and so did his friends). She dressed in her black skirt heels with a white.
