A brother and sister, both religious and sexually frustrated, find themselves alone in their childhood home. The sister, Michelle, has always been haunted by her religious upbringing, her guilt and shame a constant companion. When she catches her brother masturbating in the bathroom, she can't help but feel a pang of jealousy. She wants to feel that way too, to be free from her guilt, if only for a moment. They decide to explore their desires together, a secret between them. They start slowly, touching each other's most intimate places, hesitant at first, but soon they're lost in a whirlwind of pleasure, their bodies moving in sync, their moans echoing in the empty house.
