Mrs. Makoto is a 10-year-old boy's mother who always energetically supports her family as an excellent wife and mother. Even amid economic hardship, she steadily earns money through stock trading to save for her child's education. Her husband also values family time despite his busy schedule, making him a wonderful father. The happy family life they've built together is praised by those around them. However, there's just one dissatisfaction—her intimate life with her husband has recently come to a halt. During quiet afternoons, she indulges in masturbation while fantasizing about being forcefully taken by a delivery driver.
