In a private room, Liam's stepsister, her eyes hooded with desire, climbs onto his lap, her ass rubbing against his crotch. She grinds slowly, her breath hitching as she feels his growing hardness. Turning around, she faces him, her hands on his knees, and begins to twerk, her asshole and pussy on full display. Liam, unable to resist, reaches out, running a finger along her wet slit, making her gasp and clench her asshole, eager for more.
