I'm home bored. I haven't had sex in a long time and I don't want to masturbate. I want a real cock. I call a friend to fuck but he's out of town. My step-brother is home. But this is a really bad idea. He's my step-brother! After thinking about it for a moment I text him. He's playing video games in his room. I send him a picture of my tits to distract him. He doesn't like this and threatens to tell our parents. I try to convince him with more pictures but he resists and tells me I'm disgusting. I'm his step-sister and that's really wrong. I show him my pussy and he gets hard. I just want a picture of his cock. He refuses to show me how hard he is. Finally after several pictures I get a picture of his cock! My own step-brother's cock is huge. I'm so horny and can't resist, I go to his room and jump on him. He resists, he doesn't want his step-sister to ride his cock. After he feels my wet pussy on his cock he changes his mind. We start fucking in different positions. He's my own step-brother but I love his cock. Our parents aren't home. My step-brother fucks my pussy so hard. I never thought I'd see my step-brother thrusting his cock in and out of me. I ask him to cum inside my pussy. He leaves his huge load inside me. Weeks later I have to take a pregnancy test.. FUCK!! Did my step-brother get me pregnant?
