Six months ago, when Saya and her husband visited her father-in-law, he unexpectedly kissed her while drunk. Perhaps her father-in-law did not remember, but Saya could not forget the kiss from him. Today, when the couple visited her father again, Saya felt anxious, worried that the past incident might happen again. However, the night passed without any incident, and Saya was 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 had not forgotten that kiss, and Saya was in great need of money, as her husband's salary made her feel ashamed when dining out with friends. Without waiting for her consent, her father-in-law rushed to kiss her passionately on her soft lips. He licked her entire body, stimulating all the sensitive spots on her. Saya wanted to resist, but her body did not listen, craving more, wanting to enjoy the sensations that her husband could not provide. From then on, she continuously let her father-in-law have sex with her, and each time he rewarded her with money. Despite returning 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...
