Movie description: "What My Sister Wants". Kacie Castle has decided that she wants to fuck her stepbrother Tony Martinez, and she'll stop at nothing to get her way. She starts out trying to flirt normally, but Tony rejects her advances. Then she tries approaching him wearing just a bra and thong. She asks if he likes her outfit, and Tony tries to tell her to go change into something more appropriate. Kacie instead crosses the room to sit next to him on the couch and places her hand on Tony's thigh. Eventually, Tony bounces from the room because his sister is creeping him out. Later, Tony is in the shower when Kacie sneaks in and sits down on the toilet. Tony is shocked to see her, and even more upset when she steals his towel. Kacie offers to dry Tony off and he agrees if she doesn't do anything weird. As she's drying him, Tony gets a boner that he can't hide. Taking Tony's stiffie in her hand, Kacie leads her stepbro to the bedroom while promising that no one needs to know. Once she has him right where she wants him, Kacie strokes and sucks Tony to total hardness and then turns around so he can stick it in doggy style. Once Tony gets a taste of Kacie's tight fuck hole, he isn't really interested in stopping. He wraps his big hand around Kacie's neck and keeps pounding away at her, even as she falls to her side with her knees curled high. Then Kacie rolls onto her back and hooks one ankle over her stepbrother's shoulder to hold him nice and close as he keeps on banging her. He tries to pull out when he's ready to cum, but Kacie wraps her legs around him to ensure the creampie she desires.
