While using the bathroom, Michelle stumbles upon her stepbrother in the ensuite. He's sprawled on the counter, naked and stroking his massive cock. She freezes, then watches, transfixed, as he brings himself closer to climax. Their eyes meet, and before she knows it, she's joining him, stripping off her clothes, and climbing onto the counter. He spreads her legs, revealing her glistening pussy, and guides his thick cock inside her.
