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.
