Extremely typical NTR with a boss stealing his subordinate's wife, only difference is that the MC is the boss doing the stealing. He uses a lie that Natsumi's husband is using company cash illegally to get her to cooperate. Natsumi, of course, has only ever had sex with her small-dicked husband and becomes easily enraptured with the MC's sex technique, despite the blackmail.
