After sampling too many diuretic energy drinks, Emi and her subordinate are accidentally locked in the records room overnight. Desperate to pee, she squirms until she can no longer hold it, orders him to look away, lowers her panties, and urinates noisily into a nearby bucket—unaware that he is secretly filming her. With that footage as leverage, he later makes her hold her bladder during a meeting while controlling a remote vibrator. She eventually loses control and publicly wets herself, then is forced through repeated piss-soaked sex as urine and squirt spill everywhere.
