A perverted plain office lady who has been trained in-house by the sexual harassment department manager and has become a female

I'm a plain office lady who doesn't stand out at work. That's how I am... I have a fetish that I can't tell anyone about. For some reason, I get excited when I see Section Chief Shimada, who is disliked by 80% of female employees at work, or 90%. His face is big and creepy, his breath smells bad, and his physiologically unacceptable way of speaking. However, there is a person who masturbates by Chief Shimada fantasizing about being raped. I definitely didn't want anyone to know about this, but it turned out to be revealed by Section Chief Shimada.
