Strong-willed office worker Haru Minato is about to report senior employee Sato for sexual harassment when he sprays her with an aphrodisiac and leaves her helplessly aroused. Over three days she is locked in office and storage-room lockers, denied the toilet until she wets herself, collared, trampled, and forced to take brutal deep-throat oral until she drools. As the drug strips away her restraint, she begs to suck cock and is made to lap water from a bowl like a pet. The abuse continues at a business-trip hotel with black stockings, oily footjobs, vibrator-induced squirting, and a forced creampie.
