Rei Kitajima's final work announcing her retirement. Before filming, she was fitted with a chastity belt to enforce strict self-control. The moment the key was removed, infinite lust buried within her body exploded. Her eyes rolled back as she reached climax, foaming at the mouth while convulsing, then stiffening into heavenly ecstasy—an utterly intense spectacle. This last FUCK encapsulates all the lewd, depraved eroticism she's shown throughout her career. Her appearance will captivate viewers and leave a lasting impression forever.
