Kyle Mason is getting ready to watch a movie in the living room when he is joined by his stepsister, Sia Lust. Sia is getting settles in when she mentions that she knows Kyle’s dad wants to watch the movie, too. Kyle says that his dad is in the shower, but Sia decides to pop into the room to say hi to him anyway. Before Kyle can react, Sia has bounced off to sneak into the bathroom. She slips inside and clearly has her way with her step dad, but she believes that Kyle is clueless. Little does Sia know that Kyle was listening at the door and heard everything.
