My sister, who is about a year and a half older than me, was the first to discover my talents and my tool. This summer she undressed me in the shower ...at the beach and sucked my rod until I screamed and filled her mouth with my immature semen. After that, we copulated or ate each other every chance we got, and since our parents were in the process of getting a divorce and were both courting other lovers, we had plenty of opportunities. My sister was using a long-term contraceptive she assured. I was nervous, but caught myself starring at his crotch, he caught me too. As I sat there in silence on the edge of his bed, he moved closer and stood right in front of me. I looked up, and starred at his belt buckle as he slowly began to undo his pants.So very eager to suck and taste cock again, I slide down to my knees in front of him as he let his pants fall around his ankles, leaving his hanging cock just inches from my face. I wanted this so much and leaned in, running my lips along his. When she said that him and myself fucking lost it I blew my load in her knickers which I took and he did it in her cunt.After awhile I heard the door open it sounded like her going into the toilet,(one thing you should know about my mother she doesn't like locks on doors so she tends to leave the toilet and her bedroom door open).I snuck to the toilet door and there she was naked and so sweaty could smell the spunk of the slut,Im not great with breast sizes but they wer nice and saggy.I love. She smiled and asked "how was the night.?" I took hold of her breast from behind and said " it should have never ended." I was squeezing breasts again and my crotch was pressing her hips.I asked,"why you did not stop me in auto." "the moment I sat on your lap , I expected some such move from you.If you would not have held my breast having me on your lap in that dark night then I would have thought that you are an impo. But you did more than I expected." I unhooked bra and removed it from body..
