[JUKD-714] Mother-in-law Sayoko Machimura (Censored)

Keiko (Machimura), who was separated from her husband by death, decided to marry Masahiko because of a connection. They were a good couple, but their son Shunichi, who has been raised by Masahiko as a single man, does not find Keiko's existence amusing. One day, Koike, an insurance agent who took care of her husband after his death, appears in front of Keiko. Koike forcibly plays with Keiko's body as if to break the happiness by getting into the couple's love nest. And Shunichi happens to see it... A chain of misfortune begins.
