A year after their marriage, dissatisfaction with many aspects between Kojima and her husband grew day by day, which culminated in him making the difficult decision to send her to her father's house for a week. From the first night, her lewdness was manifested by masturbation in the bedroom, but her soft moans could not reach the ears of her father-in-law, who was old but still very prolific and interested in sex. This is the beginning of the upcoming long series of days of the beautiful daughter-in-law immersed in the sensuality of incestuous love affairs with none other than her father-in-law.
