Just arrived from the countryside to visit his son and daughter-in-law, the eager father immediately noticed Matsunaga's daughter-in-law with her rosy skin. He couldn't stop praising her beauty. After several times unintentionally seeing her cleaning the house, the beastly nature within him began to awaken. He then devised a perfect plan. He ordered an aphrodisiac online and, taking advantage of the daughter-in-law's busyness, he pretended to care for her and gave her a glass of water laced with the drug. Soon after, she began to feel uncomfortable, her body heating up, and just then the despicable father suddenly appeared like a hero, taking advantage of the situation to take advantage of the obedient daughter-in-law.
