Max Fills, the neglectful stepbrother, has a new fixation: his thick-hipped stepsister Hailey Rose and her curvy friend Amanda Thickk. He ignores them, leaving them to their own devices, but that only fuels their free-use fantasies. They use each other, fucking whenever the desire strikes, their bodies always ready and willing. But Max soon tires of their independence and decides to assert his dominance. He uses them both, whenever he pleases, turning them into his personal sex objects, always ready and eager to serve his needs.
