In the heart of Argentina, a brother and sister find themselves alone and horny. The sister, a raven-haired beauty, starts to touch herself, her moans filling the small bathroom. Her brother, unable to resist, joins in, his cock hardening at the sight of her. They masturbate together, the sister's fingers working her clit while her brother strokes himself, their eyes locked. The sister, her pussy throbbing with need, begs her brother to fuck her, but just as they're about to cross that line, a noise from outside the door brings them back to reality.
