Under the cover of night, a brother and sister, driven by primal urges, succumb to their incestuous longing. She guides his massive cock into her tight, untouched pussy, gasping as he fills her completely. He grips her hips, thrusting deep, their bodies slapping together in a rhythm as old as time. They fuck with reckless abandon, their cries echoing through the empty house. As they reach their peak, they collapse, spent and panting, their secret safe in the darkness.
