Touko, who works as an executive at her husband's company, has long since lost sight of their marital relationship, having strayed with numerous lovers. When a new, earnest and innocent young employee named Saji enters the company, Touko finds herself secretly lusting after him. One day, an opportunity arises: her husband asks her to take his place on a business trip. Seizing the moment, Touko orders Saji to accompany her, claiming it will be "good experience." Upon arriving at the hotel, she invites him to a celebratory drink and proceeds to sate her hungry pussy with Saji under the guise of "education."
