Naoh is married to her husband and lives with her father-in-law. Her sex life with her husband is bland, but Naoh was satisfied. However, as the months and years passed, the frequency of their acts decreased. After all, Naoh's libido is intense, and her husband's stamina reached its limit.

Initially, he thought it was part of her acts with his son, but looking back at the diary, he noticed that her behavior started changing around the time their acts decreased and stopped altogether. One day, when her husband went to work and her father-in-law left for an errand, Naoh was enjoying her alone masturbation time. However, her father-in-law returned after forgetting his errand. He saw Naoh engrossed in masturbation with a surprised expression but got excited seeing her pathetically gasping. He then took Naoh by force. Her father-in-law's experienced caresses were incredible, especially his relentless cunnilingus that made her orgasm multiple times. Her father-in-law's member was bigger, harder, and more erect than her husband's, and Naoh reached an orgasm the moment she was penetrated. A few days later, when the family was out, Naoh alone fumbled and took her father-in-law's underwear from the laundry basket to sniff it gently. Remembering her acts with him, as she slid her fingers down to her crotch, Naoh's underwear was shamefully wet...
