Being seen in public with your step-sister can be embarrassing, especially when she's twerking the night away. So when River asks her stepbro Tony 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 step-sister can twerk well and she has a nice ass! Tony got a little too distracted watching his step-sister's cheeks bounce when she catches him watching her. River can see the bulge in her step-brother's pants. She lifts her shirt to tease him with her perky teen tits. River knows her parents aren't home, so she lets her step-brother feel her boobs. River is curious about the bulge in his pants so she pulls out his cock and marvels at her stepbro's big dick. Tony lets his step-sister suck him before she twerks some more, teasing him to fuck her from behind. Tony spears his step-sister's pussy, pounding her hard from the back as her ass jiggles and sways. River grinds her fluffy muff on her stepbro's big dick, giving herself an intense orgasm. Tony takes River in missionary, slamming her twat til she cums again. Tony unloads in River's mouth and she swallows her step-brother's cum. River has proven she can twerk and a whole lot more!
