One night, while working too hard to even spare a trip to the bathroom, Nanami and her subordinate end up locked in the document room. When they realize they can't go outside until morning, their urge to pee grows stronger. Nanami secretly squirms and squirms, crosses her legs, and bends, but he guesses, "Maybe you're holding in your pee? lol." As her subordinate showers her with vulgar looks, Nanami makes up her mind, tells him to look away, takes off her panties, and urinates into a nearby bucket. The sound of water echoes through the room, and the pee overflows endlessly for a long time... her subordinate is secretly peeking in on all of this.
