In the dimly lit hallway, a curious look passes between step-siblings Michelle and her brother. Their parents out, they're left alone, their eyes wandering over each other's bodies. Michelle's mind drifts to the taboo, her pussy dampening as she imagines his thick cock. He catches her gaze, his cock stirring. They retreat to separate rooms, but the tension's palpable. Michelle strips, her fingers finding her clit, her moans echoing. Her brother, unable to resist, joins her, his massive cock in hand. They masturbate openly, their lustful eyes locked. Just as he's about to move towards her, a noise startles them, forcing them to quickly dress and part ways, leaving their incestuous desires unexplored.
