Chisato and her husband returned to their parents' home for the first time in a while. - My husband's parents live with his father-in-law and brother-in-law. - The two were happy to be back home after a long time. - Chisato leaned on her skills and served home-cooked meals for the two men in the household. - Then my brother-in-law told me that a delicious liquor store had opened in the neighborhood. - Chisato and her husband both like to drink, so they immediately went out together. - A few hours later, the two men returned home in a state of staggered inebriation. - When his father-in-law hurried to release the alarm, his son lay down on the sofa in the living room and fell asleep. - Father-in-law picks up Chisato and puts her to sleep on the futon in the guest room. - Just when she thought she had to carry her husband too, Chisato, who thought her father-in-law was her husband, refused to let go and begged for a kiss. - My father-in-law was confused, but he swallowed and kissed the woman's body he hadn't seen in a while. - Then Chisato begged for more and started asking for caresses. - The father-in-law, who cannot escape, begins to caress Chisato. - I was concerned about my son on the sofa, but it gradually escalated and I ended up crossing the line. - While covering Chisato's panting mouth, the act continues while worrying about her son. - Then my brother-in-law, sensing a disturbing atmosphere, quietly came over. - A drunken brother, father and brother's wife are having sex. - My brother-in-law couldn't help but take a photo of the situation. - When her father-in-law finished and the act was over, Chisato began to take a deep breath, perhaps feeling refreshed. - My brother-in-law also left the place quietly. - The next day, Chisato appeared while her brother-in-law was grinning at something. - Chisato was shocked when she went to show her brother-in-law a quick look. - It was a photo of yesterday's action with my father-in-law. - Chisato panics and her brother-in-law tells her that he will keep it a secret if he does the same for her, and Chisato nods and entrusts her body to her brother-in-law...
