A janitor with a peculiar fascination for cleaning toilets in an office building takes pleasure in the smells of urine and feces. The after-lunch hour is her favorite time, as that is when the office ladies typically come to relieve themselves. She discreetly waits and listens for them to enter the restroom.
On this particular day, she is caught peeping by a lady who angrily pushes her. Fearing the worst, she is surprised when the lady spreads her legs and urinates in her mouth, followed by making her perform oral sex to clean her. What a turn of events!
