In the cramped confines of their childhood home, a brother and sister find themselves in a situation they never imagined. As they huddle together in a closet, trying to hide from a storm, the close quarters and the tension between them lead to something neither can resist. They start to touch each other, their hands exploring places they've never been before. The sister guides her brother's hand to her breast, while he tentatively touches her between her legs. Their breaths come in ragged gasps as they give in to their forbidden desires, their bodies pressed together in the darkness, the sound of their lovemaking drowned out by the thunder outside.
