Seven years ago, during an undercover investigation, agent Melody arrested the boss of a vicious organization, but her trusted partner was killed. After his release from prison, she is captured by the worst man she ever encountered. The boss of that organization, who used synthetic drugs to addict women and sell them, now turns her into a drug addict herself. Waking up in a dazed consciousness... This is a recording of FJIN-140 "Blonde Investigator Captured by Tentacle Organization and Confined as a Flesh Onahole: Melody Hina Marks".
