Under the cloak of night, siblings, Chief Greenleaf, find themselves alone, bored, and horny. With the house silent, they retreat to their rooms, but the walls are thin, and the sounds of self-pleasure echo. The brother, hard and throbbing, can't help but imagine his sister's tight body. She, too, pictures his thick cock as she fingers her wet slit. Their late-night encounter is interrupted by a creaking floorboard, leaving them breathless and yearning for more.
