Kanade was secretly carrying out missions abroad as a covert operative, but due to a minor mistake, she was brought back to her home country and enrolled into a re-education program. Her body possessed a critical flaw: intense sexual stimulation triggered uncontrollable, overwhelming orgasms. To achieve complete domination over her mind and body, the instructors began her training with no limits, using any means necessary. However, her reactions proved far more extreme than anticipated—her lewdness and writhing agony gradually stripped the instructors of their composure, drawing them into the depths of their own desires. As a result, her body became not just a site for training, but a boundless abyss of pleasure, consumed by the instructors' unrestrained lust.
