You hear your step-sister sneak out of the house Friday night, so you decide to stay up to give her a little scare when she comes home. When she finally comes shuffling in, you turn on the light to freak her out. She gets mad, but she’s relieved it’s not her mom. She tells you that she went to Samantha’s party and brought back a bottle of wine. She doesn’t know why you act like it’s a big deal; you could have gone to the party too if you weren’t such a lameass. You decide to tease her a bit about telling her mom on her. When she takes off her jacket and you can basically see her nipples through her top, you decide to up the ante a bit. You ask to see her tits, and she agrees since you can basically see them already (plus she wants you to keep your mouth shut). She jokes around with you and makes you share the wine with her, but then she sees that you have a boner. She laughs and calls you a perv since she’s technically your sister. But, she says she’s curious to know what your dick looks like, so she tells you to pull it out. Her face says it all and she can’t believe how nice your dick is. She teases you some more and shakes her ass while telling you to stroke. Before long she gives in and tells you that she’s going to suck your dick. She drops down to her knees and tells you how good she is at giving blowjobs. She starts sucking your cock, getting it messy, and jokes about how you’re hard for your sister. She likes how dirty it feels to be sucking you, and soon she’s begging you to cum in her mouth!
