In the quiet of their shared home, a brother and sister, both with pent-up desires, find themselves alone and curious. The sister, Michelle, starts by exploring her body, her fingers dancing over her wet, aching pussy. Her brother, catching her in the act, joins in, his thick, hard cock tenting his shorts. They argue, but the tension only builds. Soon, they're naked, Michelle's eyes locked onto her brother's massive cock. She fantasizes about it filling her, and just as they're about to act, a noise stops them, leaving them breathless and wanting.
