Locked in a basement during a storm, siblings turn to each other for comfort, their bodies pressing close in the cramped space. The sister, her heart pounding, takes her brother's hand and guides it to her breast, her nipple hardening at his touch. He explores her body, his fingers slipping into her wet panties, her hips bucking against his hand. She returns the favor, her small hand wrapping around his thick cock, her thumb rubbing the pre-cum from the tip. They fuck hard and fast, their bodies slick with sweat and rain, their cries of pleasure echoing through the empty house.
