Bradley Remington, the strapping stepbrother, is in the shower when he hears his step-sister Mandy Muse masturbating in the next room. Intrigued, he turns off the water and listens. Mandy's moans grow louder, and Bradley can't help but stroke his cock to the sound. Suddenly, Mandy bursts into the bathroom, catching Bradley mid-act. She's shocked but intrigued, her eyes lingering on his thick, hard cock. Bradley, emboldened, asks her if she wants to touch it. Mandy hesitates, then nods, stepping closer. Bradley guides her hand, showing her how to stroke him. Mandy's touch is tentative at first, but she soon finds a rhythm, her small tits heaving with excitement. Bradley's cock throbs in her hand, and he knows he needs more. He turns Mandy around, bending her over the sink, and plunges into her virgin ass, making her gasp and moan as he fucks her hard, filling the bathroom with the sound of their flesh slapping together.
