Michelle, the elder sister, is cleaning the room when she notices Elle's hidden stash of vibrators and erotic novels under the bed. Intrigued, she decides to investigate, picking up a book and flipping through its steamy pages. Suddenly, she hears Elle's soft moans from the bathroom. Unable to resist her curiosity, Michelle quietly opens the door to find Elle, naked, pleasuring herself in the shower, her body glistening with water and desire. Michelle watches, her own body responding to the illicit sight, as Elle brings herself to a shuddering orgasm.
