Jason has come to visit his step-niece, Allie Addison, and his stepsister, Harmony Wonder. Uncle J asks Harmony if she wants to go to the fair with him, and the girls end up arguing as Jason walks in. He says if the girls get along, he’ll take the two girls. Instead of making things better, Uncle J’s offer makes it worse. The girls start arguing and Harmony reveals that she must be the favorite because Jason let her suck his cock once. Jason points out that it was supposed to be a secret, but the damage is done. Now Allie wants to suck Uncle J.
The girls chase Uncle J into the bedroom and corner him on the bed, where Allie relieves him of his pants and starts sucking. Harmony isn’t about to let Allie have fun. She stands there for a moment, palpating her small tits and fat ass until she can’t resist the temptation for a moment longer. She changes places with Allie, but it doesn’t take long before the girls start sucking together. Harmony finally stands up and slides on Uncle J’s cock as Allie helps her feel good. Then the girls change again.
After another BJ, the girls each take turns climbing on top of Uncle J so they can explore what it’s like to ride his cock. Harmony gets the first try, but it doesn’t take long before Allie gives Uncle J a reverse cowgirl ride. Girls love Uncle J’s big cock as Harmony takes it on his back while Allie rides his face. Next, Allie mirrors Harmony’s previous position, with her stepsister’s pussy over her mouth. On her stomach, Harmony takes it from behind as she feasts on Allie, who is also on her stomach. As Uncle J approaches ejaculation, the girls lie down side by side so that he can fuck them both. They end their threesome with their mouths open to welcome his nut on their faces. Now the girls get along well to go to the fair in a happy group.
