Reiko has been feeling stressed lately because her husband is tired and doesn't want to have sex at night. On top of that, he's been traveling more frequently recently, leaving them hardly any time together. One day while jogging, she meets a young man from the neighborhood. He seems energetic and innocent, which arouses her sexual desires. She decides to tease him by wearing revealing workout clothes purchased online, showing off her enticing bare chest and exposed buttocks. As they spend time together, the frustrated housewife can't help but act out on her pent-up needs.
