Under the pretense of a shared bath, siblings succumb to their repressed longings. The brother, his cock hard from the sight of his sister's naked body, can't resist the urge to stroke himself. She watches, her pussy throbbing, before joining him, her hand slipping between her legs to rub her clit. The room fills with their quiet moans and the sound of running water, as they pleasure themselves, their eyes locked on each other. The tension builds, and soon, they're unable to resist the pull any longer, coming together in a passionate, taboo embrace, their bodies slick with water and desire.
