Locker confinement, collar, urination, trampling. The ultimate training of a corporate slave office lady by a proud, introverted senior colleague.<br /> Office worker Hina becomes the target of narcissistic senior colleague Kanda. Her arrogant attitude is misinterpreted, and she is d** with an aphrodisiac, leaving her helpless and aroused in the office. The humiliating scene of her being locked in a small locker, denied access to the toilet, and f** to urinate miserably at work is a must-see. She is f** to serve him while wearing a collar and having her face stepped on. Her sanity is gradually broken down by the aphrodisiacs, and she is tormented in erotic outfits while on business trips, completely descending into a penitent pet. This is the complete record of Nitori Hina's descent.<br /> [Highlights] - A senior colleague's revenge leads to the injection of an aphrodisiac, and the office is violated in a way that strips the victim of their reason. - Locker confinement, followed by urinating (wetting oneself) and the humiliation of cleaning the floor. - Thorough BDSM t** including collar wearing, face stomping, and cleaning fellatio. - D** with aphrodisiacs, her sense of shame collapses, turning her into a horny bitch who craves a penis. - F** into wearing erotic clothing, using a vibrator to make her squirt, and then being repeatedly penetrated in a hotel room during a business trip.
