In an office during overtime, a male employee finds himself alone with a married MILF office lady. It begins with the words, "No one's left, so how about we fool around here...?"—a secret affair hidden from their families. A man and woman, worn out and stressed, seduce each other impulsively and give in to their desires, pressing their bodies together. But this is an office. Precisely because it's a place where they shouldn't be doing it, their passion ignites. A creampie task that can never be told to the boss begins now.
