New office lady Mizuhomisono (Mizuhomisono) is being lectured by a senior colleague for making a mistake at work when the department head Shitakawa kindly treats her. However, Shitakawa is just playing the role of a good boss; in reality, he enjoys smelling large breasts and the scent of sweaty pantyhose and has been secretly targeting Mizuhomisono. One day, male colleagues hold a welcome party for new office lady Mizuhomisono during a business trip. Mizuhomisono, who loves drinking alcohol cheerfully, keeps downing the poured drinks and ends up passing out.
