Cute, innocent-looking sister and brother find themselves alone, bored, and horny. She starts masturbating, her tiny hands exploring her wet, taught pussy. Her brother, unable to resist, joins in, stroking his hardening cock. They catch each other's eyes, desire igniting. Naked, they face off, her petite frame contrasting his toned muscles. He edges closer, his thick cock brushing her thigh. She gasps, wanting more, but a sudden noise breaks the spell, leaving them breathless and unsatisfied.
