[Chinese]JUX-535 Before the master returns... The forbidden everyday life of my brother-in-law and sister-in-law Satou Haruki

Haruki's wife, Haruki's loneliness for her husband, who devotes himself to work and neglects his family, ends up having a physical relationship with his brother-in-law, Katsumi. As she meets with her only once a week, Haruki's feelings of guilt for her husband gradually change into her love for Katsumi. One day, Katsumi decided to go abroad for work reasons. Katsumi, who takes his relationship with his sister-in-law seriously, tries to turn him down, but Haruki strongly holds him back.
