In the sun-soaked paradise of Gran Canaria, sisters on holiday find themselves in a steamy situation. One night, after a few drinks too many, they share a shower. The water cascading down their bodies awakens desires they've long suppressed. With soap-slicked hands, they explore each other's curves, their moans echoing off the tiled walls. Their shared secret becomes a taboo thrill, fueling their passionate encounters throughout the week.
