Nozomi had married a promising young employee and left her job to enjoy a happy life as a housewife, but in reality, she was forced into a master-servant relationship with her department chief, Kono. Even her marriage was arranged under Kono's orders, and while harboring guilt toward her innocent husband, Nozomi obediently followed commands, enduring repeated tied-up BDSM training sessions with various men. Through this process, her latent masochism gradually awakened, leading her further down an irreversible path toward becoming a sex slave and cumdump.
