Wearing a sleek enamel catsuit, FBX agent Kiki infiltrates as an undercover investigator but falls into the hands of her target, psychiatrist Dr. Nectar. Recalling a previous imprisonment, Dr. Nectar reuses a special restraint device once fitted on Kiki and suspends her from the ceiling. With both arms bound and immobilized, Kiki's body is fitted with vibrators and an electric massager, forcing her to experience intense pleasure. Dr. Nectar then places a rubber hood over her head, suffocating her and pushing her into an extreme state where even breathing becomes impossible.
