Kyle Mason and his stepsister Destiny Cruz both want to use the living room, but for different reasons. Destiny wants to study for her upcoming test, but Kyle wants to practice his guitar. Destiny is so desperate that she offers to give Kyle a blowjob if he'll leave the room for her. Kyle doesn't take her up on it, but it sure generates some sexual tension, with Kyle responding that he could make her cum by putting his dick in her. Destiny's next attempt to make Kyle leave is telling him that she's going to sit on his amp so he can't play his guitar. That just makes Kyle laugh as he tells Destiny that the amp is basically a giant vibrator. He tells Destiny that she'll cum if she sits on it.Destiny makes a big deal out of how the power of her mind will keep her from orgasming. In fact, even if Kyle was fucking her Destiny is certain she wouldn't get off. She proves her point by sitting on the amp despite Kyle's warnings. After just a few cords, though, Destiny is squirming at the way the vibe is getting her right off. She tries to hide her orgasm and claim she didn't cum, but Kyle doesn't believe her for a second. He tells Destiny to prove that she didn't by showing him that her snatch isn't wet. Of course her pussy is wet, and when Kyle sticks his cock inside her Destiny cums again almost instantly.Now that Destiny is all warmed up for a good fuck, they relocate the couch so they can get busy together. Before Kyle even gets her clothes off her has his stepsister in doggy. Kyle takes a seat and Destiny climbs on top of him so she can ride him in reverse cowgirl. Then she turns around so Kyle can suck her titties as she keeps her hips rocking. Destiny winds up on her back with her stepbrother pounding between her thighs. Dropping to her knees, Destiny opens wide to take a face full of hot cum as reward for a surprisingly fun afternoon.
