I work as a department head at this company. My subordinate, Niimi, is diligent in her work but not good at the sports club atmosphere. One day, at a drinking party, I was attracted by the gap in her femininity and ended up having a physical relationship. The two of us, unable to turn back, embarked on an affair... As Niimi's true nature as a masochist was revealed, I found myself inexorably turning into a sadist.
