As the rain pours down in Los Angeles, a brother and sister find themselves trapped in their apartment, their desire for each other growing with each passing moment. The sister, her body covered in a thin sheen of sweat, begs her brother to fuck her, to fill her with his come. The brother, his cock hard and ready, obliges, pushing his sister down onto the bed and plunging into her with a ferocity that surprises them both. They fuck with abandon, their bodies slapping together, their moans filling the room, until they both come, their bodies shaking with the force of their release.
