Yuka works as an executive at her husband’s company, overseeing accounting and training new employees. The business is stable, but her marriage feels more like a partnership between roommates. When earnest and eager young adult hire Saji joins the company, Yuka secretly begins lusting after him while handling his training. Chosen to take her husband’s place on a business trip, she orders Saji to accompany her “for the experience”—but education is hardly her only goal. She intends to satisfy her aching pussy and indulge every selfish desire.
