Desperate Sister Gets Blackmailed V

My best friend told me that he had sex with my sister. I didn't believe him at first, I know she is flirty with a lot of guys, but she's a good girl, she's an excellent student and when she's not studying, she has a part time job tutoring others. She tutors my friend, and I listened to him tell me how he made the moves on her, he knew I wouldn't mind.. I'm not the over protective type, you'd have to be daft to not realize that my sister is one of the hottest women in our town. I listened with interest how he told me that she wasn't that hard to get, he told me what a freak she was and how he helped play out her secret three guy gang bang fantasy she had. I couldn't believe that. I mean, I know my sister can dress a little slutty, but she's a little uptight, and I've overheard her telling her friend how proud she was of keeping her virginity as a gift to give to her husband. My friend pulled out the video on his phone and I was shocked to see my darling little sister taking it in all holes, in her mouth, her ass, her pussy. Fuck.. I am not as masculine as my friend, I guess, I've never had a woman and I'm already a senior in High School. I lie to him and tell him I've had a woman, and he urges me for all the details, "was she tight?," "what'd she feel like?," and he even asked me what she tasted like. I shrugged it off and told him, "for another time, I've got to run." I nabbed that video off of his phone when I was watching it and sent it to my email address. My friend and no clue what I had planned to do with it, and my sister is in for a big surprise tonight. I share a room with my sister. I always thought it was lame until she started growing into her womanly figure. I love my sister, but it doesn't seem like we have that typical family bond like other brothers and sisters do. Our parents sent me off to boarding school in Poland for five years, and now that my sister and I are in our formative years, we're getting better acquainted. I think there's a strong sexual tension between us. She went from wearing flannel pajamas to slinky, silky chemises in bed over the last month. I think she's into me.. I want to see if she'll let me fuck her like she let the guys in her video. I tell her that we need to talk, and she sits up in her bed with interest. I show her the video on my phone, she is horrified. Her first thought it to grab her coat, her shoes, and we'll go over to my buddy's house to make sure that video will be deleted and never see the light of day. Adriana's frantic, she goes between trying to lie to me, telling me that it is some animated version of her, and a bad one at that, it's so clear that it's her, right down to the little freckles on her back, to the same voice. She tries to bargain with me, to show me slivers of her body as she clutches herself in modesty. She can't keep her lies straight, she tells me that she's a virgin, and then later she tells me that she's only done a blow job once. My conscience is clean. My sister obviously loves sex, and she's going to love taking my cock deep into her tight pussy. I want to watch her eyes wince with pain as I pound her hard, and her pussy quiver around my cock, squeezing me, begging me to go deeper. I pinned her against the wall and fucked her as if she was my own personal rag doll. I love how she looked at me with brand new eyes, she kissed me passionately, she whimpered, begged for me to make her cum. We're going to have an entirely new relationship after this day. I'll never complain again about sharing a room with her.
