Sumie (Hatori Sumika) runs a yakitori shop with her husband. Although her husband inherited the business due to family circumstances, his naturally antisocial personality led him to leave everything in Sumie's hands. Despite this, Sumie worked hard to manage the store and carry on with daily life. However, her sex life with her husband had long been neglected, making her a lustful wife who indulged in masturbation every night. One day, she fell for an older man dispatched from a senior job center and finally gave in to him physically. From that moment, Sumie's desires awakened, and she began craving one man after another. Soon, her lust spilled into the shop itself, leading to shocking new developments.
