The Igarashi family lives in a small town. Wife Shinobu is popular, beautiful, and well-built, with a deeply affectionate relationship with her husband. Every year, her husband leaves for temporary work, and each time he's gone, Shinobu grows lonely, cherishing her private nighttime moments. As this year's departure draws near, Shinobu sees him off, looking slightly melancholy. A few days after he leaves, a package arrives—clothes and underwear still carrying his scent. Unable to resist, Shinobu spends her nights alone, indulging in masturbation. Deep down, every act is filled with longing and devotion to her husband.
