Aono, a new employee, is staying at a hotel on a business trip with her boss, whom she hates. She doesn't realize that there was an aphrodisiac in the alcohol she drank in the room... She is attacked while asleep, and her body becomes super sensitive and cums on its own. Even though she's the worst, the combination of the middle-aged man's sticky technique and the drug-induced sex brings her to a brain-dead orgasm. She is violated until late at night, drooling and sweating, and repeats her orgasms. She is creampied many times during the escalating hard piston sex, and gradually becomes addicted to the boss's dick... It seems the aphrodisiac worked too well for the new employee.
