The moment I greet Mr. and Mrs. Hatano, who have moved due to my husband's job transfer, and Mr. and Mrs. Otsuki, who live downstairs, the gears of fate begin to go crazy.She is invited to a meal by Mr. and Mrs. Otsuki, and her Yui drinks as she is told. She is carried to her bedroom by the trick of two people and is held by Otsuki husband. Yui, who was held once, is called after that and she is addicted to SEX while being tormented by her guilt against her husband.At that time, Hatanoo was also fucked by Hibiki and the physical relationship began.What will be the fate of Mr. and Mrs. Hatano who have been fucked?
