Bored and alone, a brother and sister turn to self-pleasure, their bodies on edge. The brother catches his sister masturbating, her ebony skin glistening with sweat, fingers buried in her wet pussy. Anger flares, but so does desire. They soon give in, naked and throbbing, as she begs for his thick cock to fill her tight cunt. Just as they're about to explode, a voice outside the door freezes them mid-act.
