Maki Amamiya was known as a beautiful young wife, but lately she's felt a lingering unease. Her husband, exhausted from work, comes home, takes a bath, and immediately collapses into bed, leaving almost no time for intimacy. Maki finds herself starved for attention, enduring the growing physical longing in silence. When some male acquaintances learn of her situation, they offer to relieve her emotional and physical frustration by pleasuring her in her husband's place. Tempted by their proposal, Maki begins to entertain the idea, opening herself to a new and forbidden experience.
