My step-brother is spying on me while I look through the window at my neighbors. I can't believe it. She is making out with her cousin, that is so wrong. I would never kiss anyone in my family. I see my step-brother getting really close and his dick starting to get hard. I take him out of my room, he is a sick pervert. Later when I enter my room I see my panties on the bed. It smells weird. Is it cum? WTF? Did my step-brother do this? I call him to warn him that if he does it again I will tell our parents. He is crazy. The next day while I am taking a long shower my step-brother is spying on me. What the fuck is wrong with you bro? I am your own step-sister. You need to go to the doctor. You are so crazy, you are a stupid sick guy. You can't see your step-sister naked. He doesn't want to go and leave me alone. He proposes that I help him cum and he will leave me alone. After he begs me I accept. This is so bad. It's going to be quick. I've never seen or touched his cock before. I jerk him off, he's so hard. I hear a noise in the background. Our parents have arrived home. The next day I see through his bedroom door that he's masturbating. I can't help but touch my pussy while I watch him. I make a noise with the door and he asks me to come in and sit next to him. My pussy is wet and he notices it. I want to help him cum. I start jerking him off and sucking my step-brother's cock to drain his balls. He fingers my pussy while I suck. Finally he cums in my mouth. It's a secret of ours. I can't stop thinking about Bro's cum. I text him on his cell phone. I tease him so his cock gets hard. This is so bad but it feels so good. While we talk about what happened last time, I send him hot pictures of my whole body. I want him to fuck me so I tell him I'll wait for him in doggy style in my room. He comes in and starts fucking my pussy. After fucking for a while I ask him to fuck my asshole. He's so hard and my pussy is so wet. He fucks my tight asshole in different positions. I ask him to cum inside my asshole. I love you bro. I never thought I'd love my own step-brother's cock so much.
