Unbeknownst to each other, step-siblings Michelle and her brother sneak into the bathroom for a private moment. Michelle, entranced by her reflection, slowly strips and teases her curves, fingers dancing on her clit. Her brother, oblivious but aroused, showers nearby, his cock hardening at the scent of her arousal. Caught in the act, Michelle's anger flares, but so does her desire. They decide to indulge, Michelle's eyes widening at her brother's thickness. Just as they're about to unite, a creaking floorboard stops them cold.
