Being seen in public with your stepsister can be embarrassing, especially when she's twerking the night away. So when River Lynn asks her stepbro Tony Rubino if she can go to his friend's party with him, he isn't very receptive. He tells River she can't twerk and his friends gave him hell for it for weeks after! River is a little self-conscious so goes to her bedroom to practice her moves. Tony takes the opportunity to spy on her - the truth is his stepsister can twerk well and she has a nice ass! Tony got a little too distracted watching his stepsister's cheeks bounce when she catches him watching her. River can see the bulge in her stepbrother's pants. She lifts her shirt to tease him with her perky teen tits
