This is Minami's first time returning to her husband's house, where she was born and raised. But it seems that the parents-in-law are quarrelling, the two of them don't talk or care about each other. But Satoshi said that it was because his father often drank alcohol, so Minami ignored it. The next morning, his father told him that he was sick, so Minami stayed at home to take care of him, and Satoshi went to see his childhood friends again. Minami was offered jelly by her father, and while eating, she felt extremely sleepy. When she woke up, she found herself being invaded by her father-in-law and orgasmed at any time. Since he filmed the sex scene, Minami had to comply with his wishes. Her mother-in-law found out about everything but couldn't do anything because she herself was having an affair!!
