She was stark naked, straddling a chair, and riding a large lifelike dildo, whilst vigorously playing with her nipples and clitoris.I was about to tur... and go back to my room to masturbate, when she looked up, saw me and beckoned me into the room, lasciviously licking her lips as she did so. By now I had the beginnings of an erection, and as I walked into the room, she rather pointedly looked at my groin and smiled."Come and sit down on that other chair, William," she said. "You can sit there. I felt John rubbing at my pussy from behind with his hand. My pussy was dripping juices into his hand as he did. I felt him take his hand and he smeared my juices upward between my butt cheeks. I felt his tongue lapping at my own asshole as I licked at Gina’s asshole.Gina was rocking her pussy against my fingers and grinding that lovely ass into my tongue. John had his whole tongue buried up my own asshole. DeRonda would moan then Gina, then me as we played with each other on the bed. I could. She almost fell over as she spun her head to see what had caused the searing pain in her arse cheeks. Tim laughed as he held up the twenty inch leather paddle which had just left the bright red area of skin on his mother's arse. He told her, "I never gave you permission, bitch to touch my cock let alone to take it in your slutty mouth!"A shocked and yet very excited Alison asked, "Where did you get the paddle from Tim"From Grandma was his reply and he then went on to explain that Grandma had. Even Dad followed us into the office. I wondered what was going on when Mom dialed the phone and put it on speaker."Hey, Mom, did you find your genealogy chart?" my mom asked my grandmother."I did. Now tell me again. What was the girl's name?" Lisa Felton. She's sixteen, and has a brother Billy, who is a couple of years younger," I said."Yep, here they are. Your great grandfather had two boys, Claude and Jedidiah. So you are related to Lisa." Thanks, Mom," my mom said and then hung up.Everyone.
