Edyn Blair just wants to pee in peace, but her pervy stepson Sam Shock won't let her. Sam also likes watching his stepsister Tina Rayne whenever he can. Mom and daughter are sick of Sam's perverted tendencies, so they decide to get back at him. They have their chance when Sam "accidentally" spills a cup of chocolate milk on Tina right in front of Sam, then puts her hands all over her daughter's boobs to try to clean it up. Edyn scolds him and demands that he wash Tina's clothes for her. The catch is that Sam has to get naked, too, and put up with ridicule from his stepmom and stepsis.
Now that the girls have their chance to let Sam know how it feels to be touched and judged without consent, they take it up. Tina grabs Sam's dick and leads him to the bedroom, where she gives him a handjob until he's nice and hard. When Edyn joins her daughter and stepson, the two girls go to work implementing their master plan. They take Sam for a ride, with Tina getting the first opportunity to whip out her titties and straddle Sam's fuck stick. Meanwhile, Edyn plants her greedy snatch on Sam's face to silence his protests.
Sliding forward, Edyn gives Sam a reverse cowgirl ride. Then she urges Tina onto her hands and knees so Sam can fuck her juicy pussy until she's moaning. Edyn takes one final pussy pounding, keeping Sam playing stud until she cums. Only after the girls have gotten dressed do they agree to let Sam get off. Working together, they give him a dual handy until he pops his load all over his stomach, leaving him covered in his own cum with his lesson learned.
