On their first long holiday since Tsukasa and Hiroto got married, the two decided to visit Hiroto's hometown. Hiroto's parents treated Tsukasa very well, but she felt like something was off between them. The next day, as they were getting ready to visit the Yoshida family, they suddenly heard Hiroto's father shouting in pain. His back was hurting, so Tsukasa decided to stay back to take care of him while Hiroto went to the Yoshida household. After applying ointment on his father, Tsukasa found out the reason why Hiroto's parents seemed distant from each other. It turned out that Hiroto's mother was having an affair with a younger man! His father offered Tsukasa some alcohol, intending to refuse but wanting to comfort his father, Tsukasa agreed. After just one glass, Tsukasa felt dizzy and fell asleep. When she woke up, she found herself being licked all over by her father-in-law! Her body felt heavy, unable to move, leaving her only able to lie still and watch as her father-in-law took over her entire body. Even with Hiroto's mother standing nearby, his father continued to violate her as if to tease his wife. Initially feeling disgusted and ashamed, the skilled touch of her father-in-law gradually made Tsukasa's body yield and enjoy this sensation of pleasure...
