In the sweltering bathroom, Michelle's fingers dance over her slick pussy, her moans echoing off the tiles. Unbeknownst to her, her stepbrother is just on the other side of the door, his cock hardening at the sound. As he bursts in, water cascading down his lean body, they lock eyes, Michelle's hand still buried between her legs. The air crackles with tension as they argue, but soon give in to their forbidden desires. Naked, Michelle watches, captivated, as her stepbrother strokes his thick cock. She can't help but imagine it inside her, stretching her tight pussy. But just as they're about to give in to their lust, a sudden knock at the door forces them apart.
