Locked in their shared room, the siblings succumb to theirbidden curiosity. The brother, his cock straining against his jeans, watches as his sister, clad only in a thin nightgown, dances sensually for him. She notices his erection and, emboldened, straddles him, rubbing her wet pussy against his hardness. He grabs her ass, pulling her closer, as they grind together, their breathing ragged. Their bodies yearn for more, but they're torn between desire and the taboo that binds them.
