Bianca Bangs and Madison Wilde are working on boxing as a form of self defense and also because there’s a fight coming up that they’re very passionate about. When Parker Ambrose, Bianca Bangs’s stepbrother, comes out and asks what they’re doing, the girls argue about who’s going to win. Later, Parker comes across Bianca training topless. Madison rips her own shirt off, too. Knowing that Parker is watching, the girls argue even harder, going chest to naked chest. Later, Parker comes to Bianca’s room to see that the girls have made up. Since no one technically lost, they agree they can fuck Parker together. Crawling across the bed, they pull out Parker’s stiffie and go to work together. Soon they’ve both removed their shirts as they slurp and suck down Parker’s hardon.Bianca takes the first spin on Parker’s hardon as he lays on his back. Riding in reverse cowgirl, Madison relieves Bianca so Bianca can ride her stepbrother’s tongue. Once Bianca has sucked the trio’s juices from Parker’s cock, Madison gets on her knees to eat Bianca out while Parker does her in doggy. Bianca is the final recipient of Parker’s ministrations as she spreads her thighs for him. He rewards her dedication with a creampie that leaves her dripping with her stepbrother’s love.
