Confined Carnality: Guilt-ridden Grinding

Under the same roof, a brother and sister find themselves alone, their bodies yearning for release from pent-up desires. She touches herself, her moans echoing through the empty house. He catches her in the act, his curiosity piqued. They argue, but the tension is palpable. Later, they come together, naked, their bodies yearning for each other. She takes his cock in her hand, feeling its thickness, imagining it inside her. Just as they're about to give in, a noise from outside breaks the spell.
