In the stifling heat of the summer, two unsuspecting siblings find themselves in a compromising position. As they struggle to set up an old fan in the attic, their bodies press together, their breaths hitching as they feel the undeniable spark between them. They try to ignore it, but as the fan finally starts, its hum drowns out their inhibitions. Before they know it, they're locked in a passionate embrace, their hands roaming, their bodies writhing. They stumble down to the empty house, their clothes left behind as they give in to their primal urges. In the cool darkness of the basement, they explore each other's bodies, their fingers and tongues bringing each other to the brink of ecstasy. As they come together, they collapse, their bodies slick with sweat and their hearts pounding with the thrill of their forbidden love.
