In a cramped closet, Michelle and her brother squeeze close, their bodies pressed together. Michelle's breath hitches as she feels his massive, semi-hard cock against her thigh. She knows it's wrong, but her body responds anyway, her pussy growing wet. Her brother, equally aroused, struggles to maintain control. Their father's voice echoes in their minds, "You mustn't move!" But Michelle can't help it, she grinds against him, feeling his cock harden further. He responds, his hands gripping her ass, pulling her closer. They're lost in their forbidden lust, oblivious to the world outside.
