Bianca Screws and Madison Wilde are working on boxing as a form of self defense and also because there's a struggle coming up that they're highly spunky about. When Parker Ambrose, Bianca Bangs's stepbrother, comes out and asks what they're doing, the gals argue about who's going to win. Later, Parker comes via Bianca teaching topless. Madison rips her own t-shirt off, too. Knowing that Parker is watching, the gals argue even harder, going torso to naked chest. Later, Parker comes to Bianca's guest room to watch that the gals have made up. Since no one technically lost, they agree they can drill Parker together. Crawling via the bed, they extract Parker's stiffie and go to work together. Briefly they've both liquidated their t-shirts as they munch and inhale down Parker's hardon.Bianca takes the first flip on Parker's hardon as he lays on his back. Railing in switch sides cowgirl, Madison eases Bianca so Bianca can rail her stepbrother's tongue. Once Bianca has sucked the trio's testicle tonic 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 opens up her thighs for him. He prizes her dedication with a internal ejaculation that leaves her running in rivulets with her stepbrother's love.
