Shimokawa just plays the role of her good boss, and her actual personality is a metamorphosis that likes to smell big tits and stuffy pantyhose, and she secretly aimed at Mizuho. One day, a male employee will hold a social gathering at her business trip to welcome new office lady Mizuho. Mizuho, who likes to drink liquor cheerfully, drinks up the poured liquor and crushes it.
