Department head Kita travels to the countryside with several employees for an important business meeting and stays at a nearby hot-spring inn. After the banquet, new employee Honoka Furukawa invites him to continue drinking. The quiet office newcomer gets him drunk, slips into his room, and transforms into a commanding seductress. She toys with the middle-aged boss, repeatedly edging him at the brink before finally making him ejaculate, then keeps going until he has nothing left.
