In the midst of a heated argument, a young stepsister lashes out, "Fuck me, stepbrother, then shut up!" Her words hang heavy in the air, shocking them both. Before either can react, she lunges at him, pushing him onto the bed, straddling him. She grinds on his growing erection, her tight pussy soaking through her panties. He tries to resist, but her lust is infectious. She pulls down her panties, revealing her glistening slit, and guides his cock inside her, riding him silently, their arguing forgotten in the heat of their forbidden passion.
