“That’s a good, obedient girl, boss. You deserve another reward today.” Meguri is the sales manager at an office-equipment company in central Tokyo. She devotes herself completely to work while her marriage has gone cold, and the pressure keeps mounting with no way to relieve her stress. She is also plagued by Yoshino, an unmotivated subordinate. One day, she lets her guard down and he discovers her submissive, masochistic desires. Yoshino begins summoning her to a shady hotel during lunch breaks, using the pain and pleasure of S&M sex to train his boss into an obedient pet.
