In the sun-drenched coastal town of Argentina, siblings find solace in each other's arms, far from the watchful eyes of their parents. The sister, a sultry brunette, teases her brother with glimpses of her toned body as she sunbathes on the terrace. He, unable to resist, sneaks peeks from his bedroom window, his cock hardening at the sight of her. One evening, after a few drinks, they succumb to their desires, fucking fiercely and feverishly on the cold, hard tiles of the terrace, the moon their only witness.
