IESP-500 Undercover Narcotics Investigator Tsubomi Is Captured and Degraded by Drug Traffickers

Undercover narcotics investigator Tsubomi, along with a colleague, raids a drug trafficking organization, but the mission goes wrong when the colleague is knocked out and Tsubomi is captured. She is restrained by men in black and forced to ingest the drugs she was meant to seize, then subjected to further abuse while unconscious. After waking, she attempts to escape but is recaptured, leading to a series of humiliating acts including deep throating and being used as a 'drug dog' by the boss.
