Six months ago, when Saya and her husband visited her father-in-law at home, he unexpectedly kissed her while drunk. Perhaps her father-in-law didn't remember, but Saya couldn't forget her father's kiss. Today, when the couple visited her father again, Saya felt worried, fearing that the past incident would happen again. However, the night passed without any incident, and Saya was able to feel somewhat relieved. The next day, her husband went fishing early in the morning. Her father-in-law approached her and gave her a large sum of money, in exchange for being able to kiss her like before. It turned out that he hadn't forgotten that kiss, and Saya was in need of money. Her husband's salary always made her feel ashamed when going out to eat with friends. Without waiting for her consent, her father-in-law rushed to passionately kiss her soft lips. He licked all over her body, stimulating every sensitive spot on her body. Saya wanted to resist, but her body wouldn't listen, it wanted to enjoy more, to experience the feeling that her husband couldn't provide. And from then on, she continuously let her father-in-law have sex with her, each time he would give her a sum of money. Even though she had returned to the city with her husband, Saya still secretly went back to the countryside to meet her father, allowing him to have sex with her in exchange for money for herself...
