Slender-bodied Yuki Toma is known as an elite investigator. Today, she receives a Class A mission to infiltrate a human trafficking ring linked to a loan shark operation, with rumors of a high-ranking politician involved behind the scenes. Yuki swiftly goes undercover, taking down the gang's thugs with her signature laxative trick to rescue the captive woman. However, the victim has betrayed the investigation, siding with the criminals in exchange for debt forgiveness, and captures Yuki. She is then restrained with paralyzing drugs, penetrated with a cock, brought to orgasm repeatedly with a vibrator, and kept drugged and helpless.
