KSBJ-148 Adultery within the family Shiori Tsukada

It all started when a drunken Shiori suddenly kissed her husband's older brother who lives with her. Triggered by that, her domestic affair that she hides from her husband continues. However, Shiori is likely to find out about her husband, so she consults her brother-in-law about ending this relationship. However, her brother-in-law has taken a video of her relationship with Shiori, and refuses to dissolve her relationship with it as a shield.
