JUX-405 After my husband goes to work, I'm always alone with my father-in-law... Asahi Mizuno

Asahi lives with her kind husband Koichi and father-in-law Haruo. His father-in-law, Haruo, was kind to Asahi and told Asahi that he wanted to see his grandchild soon. However, Haruo learns that Asahi is not satisfied with the relationship between him and Koichi, and attacks Asahi when he sees Koichi off to work one morning... Then, every day after that, when the two of them were alone, Haruka repeatedly committed obscene acts.
