Shoko serves as executive director at her husband's company, managing accounting and personnel with excellent results. But her husband spends his nights drinking at clubs, leaving their marriage feeling like a business partnership. When the handsome new graduate Saji joins the company, his youth, strong body, and innocent eyes awaken her desire, and she secretly masturbates while imagining him. Given the chance to travel for a sales meeting, she orders Saji to accompany her under the pretense of experience—when her real goal is to satisfy the lust she has been hiding.
