Yoha Ishikawa, from the Human Resources Department, comes to work in a sleeveless shirt every day during the summer, unconsciously exuding a refined eroticism that draws the attention of the male employees. As a result of trial and error in order to see her naked, who is always kind and considerate of others and who is in charge of personnel interviews with employees, it turns out that she has an incredibly erotic constitution that makes her cum hard during sex. The contrast with her usual self is amazing.
