As the rain pours outside, a brother and sister, isolated and horny, find solace in each other's arms. The girl, her pussy dripping with desire, grinds on her brother's thick cock, their bodies slick with sweat. He fingers her, making her moan, as she strokes him to the brink. Their hearts race, and their bodies tense, as they teeter on the edge of orgasm, their moans echoing in the room. Just as they're about to explode, a noise from outside breaks the spell, leaving them panting and yearning for more.
