Incestuous siblings' hidden pleasure

Locked in their shared home, a brother and sister find solace in taboo masturbation as their parents argue downstairs. The brother, hidden by the bathroom door, listens to his sister's moans as she pleasures herself, her fingers tracing her slick folds. When he bursts in, catching her in the act, they clash, but later, they admit their mutual desire. Naked, they stroke and tease each other, the sister's eyes widening at the sight of her brother's thick, hard cock. As they're about to go further, a creaking floorboard stops them, leaving them breathless and yearning.
