These siblings, left alone in their creaking family home, find solace in forbidden pleasure. The teen girl, frustrated with her pious upbringing, begins to touch herself, her fingers dancing over her wet folds. Her brother, drawn by her soft moans, finds her in the act, his raging hard-on tenting his pants. They argue, but lust wins. She takes him in, her eyes widening at his size, before she decides she wants it all. Just as they're about to merge, a creaking floorboard warns of an intruder, forcing them apart, panting and red-faced.
