I got a plan how you seduce her and fuck her and so I came to my room and turn on my pc and I have some xxx movie cd.I insert cd and I was watching th...at and I got very horny and hot. I was naked and I am think about my sister cousin and masturbating. I was very hot and call her name Sara name changed she ask what happen and I told come here and I hide myself behind door and the movie was playing.She came inside room and search for me and call my name and she saw on pc xxx movie was playing she. . but obviously not if she'd been fucking with this nasty ass nigger.He slapped my ass and I cried out, not so much in pain but in pleasure. The pleasure intensified, he rubbed it and licked and I could feel my balls tighten up. He pushed on finger in and then with a slight pop sensation, my ass was penetrated for the first time ever. I cried out in pain."Please Duke, stop!" I begged, my voice weak with feeling this strange sensation."Don't worry shawty, I got you. This ass I so right, I am. Tell me how it can possibly get any better than that.I didn't keep count as to how many time that Sarah and I had sex of one type or another that summer, but I know that we slept in the same bed at least twice a week. There was never any giddiness or stupid immature macho bullshit. It was just the loving relationship between a brother and his sister. Although she really did not enjoy being fucked in her ass, she did allow me to do that about once a month or so, just because it was so exciting. At that point he slapped my bare bottom with one more good smack then went into the bathroom to pee. As I was still crying naked with my face in the corner, he walked out of the bathroom toward me and told me to “shut up and bend over”. I knew exactly want to do next so I bent way over and he immediately dropped his trousers and inserted his long skinny dick into my vagina with a hard humping action. He told me I was his sex slave girl from now on and I better come over to his place.
