Locker confinement, collars, pissing, and trampling. The ultimate corporate slave OL training by an introverted senior colleague. Seina, a rookie OL with high pride, becomes the target of her senior. Forced to inhale aphrodisiacs, she is driven into heat within the office, unable to resist. A must-see scene is her humiliation when she is locked in a locker and forced to piss herself right at the workplace without being allowed to go to the toilet. Bound by a collar and forced to grovel in dogeza while being trampled upon. This is the complete record of Seina Arima's descent into a complete penitent pet over three days of office breeding. [Highlights] - Aphrodisiac injection and office ravaging driven by the introverted senior's abnormal obsession - Confinement in office lockers and breaking-point pissing (wetting herself) - Thorough humiliation through collars, dogeza, and trampling - Reason vanishes under aphrodisiacs, turning her into a bitch who begs for "cock" - Treated as a complete pet, fed from a dog bowl - Erotic costumes in the late-night office, wand massager squirting, and continuous creampies
