Stranded together in an empty house, a brother and sister find themselves drawn to each other's bodies, exploring their taboo desires. He watches her masturbate, her fingers plunging into her wetness, and she can't help but stare at his growing bulge. Their tension builds as they argue, but it only fuels their need. Finally, they give in, naked and hungry, their bodies entwined as they discover the pleasure of each other's touch.
