Wife Reina initially comes across as glamorous and arrogant, but through relentless domination after domination, she awakens to the masochistic nature hidden within her. Subjected to constant stimulation from vibrators and dildos, she repeatedly reaches climax, enduring deep-throat penetration until she's on the verge of vomiting, experiencing intense, extreme pleasure. She also undergoes humiliating experiences such as masturbating in public and being raped with creampie after groveling in apology, each incident deepening her masochism. The more intense the torment, the more pleasure she shows, fully revealing her true self as a genuine masochist.
