Yurika cares about her husband who disappeared in a foreign country. A father-in-law who treats Yurika kindly. I thought Yurika, who lives with her father-in-law and brother-in-law, was able to become a member of this family. One day I happened to see her brother-in-law's masturbation, which upsets the gears of everyday life! What is waiting for Yurika who is trapped in a family of fornication...?
