Plot Summary

Government undercover agent Karin Kitaoka infiltrates a drug syndicate’s stronghold, only to be betrayed by a junior agent and taken captive. She is forced to endure an injection of a potent, syndicate-produced drug. The substance causes violent, full-body and vaginal spasms, while hypersensitizing her entire body. Despite her repeated attempts to escape the abuse inflicted by the men, she remains trapped—a situation that escalates further when the syndicate’s boss arrives to intensify her torment. The official description highlights the progression from capture and injection to a state of continuous, convulsive orgasms. With a runtime of approximately 121 minutes, the film focuses on drug-induced hypersensitivity and multiple nakadashi (creampie) sequences. IESP-764 K2

Key Highlights of the Film

Drug-Induced Full-Body Vaginal Spasms

The core of this film is "drug-induced vaginal spasms" (yaku-zuke chitsu keiren). After being injected, Karin Kitaoka’s sensitivity skyrockets; her body trembles and convulses uncontrollably, with her lower regions reacting with particular intensity. The camera focuses on her expressions during the continuous orgasms and spasms triggered by the drugs. The combination of her uniform and the "investigator" premise creates a striking contrast. This sequence emphasizes a total loss of physical control—rather than voluntary participation—highlighting the "drug-coerced" theme that is a staple of this series.

Group Ordeals and Nakadashi (Internal Ejaculation) Following Capture

After being betrayed, the protagonist finds herself in a multi-partner scenario, where men take turns subjecting her to various acts and nakadashi. While in a state of constant spasms, Karin Kitaoka endures 3P and 4P encounters; the footage highlights bodily fluids, involuntary convulsions, and the moments of internal ejaculation. Official tags include nakadashi and 3P/4P, underscoring her transition from resistance to being completely "broken in"—a perfect fit for viewers who enjoy multi-partner scenes and themes of forced submission. IESP-764 K5

The Contrast Between Investigator Uniform and Resistance

Appearing as an undercover agent, she is initially seen in uniform, armed and composed—a stark contrast to her disheveled, vulnerable state after being captured. Her repeated, failed attempts to escape—thwarted by the effects of drugs—culminate in a powerful emotional climax when she finally comes face-to-face with the crime boss. This sequence intensifies the narrative tension and serves as a signature highlight of the "Narcotics Investigator" series.
