Hitomi Yoshimizu is 43 years old, a mother of one, and has been married for 15 years. In recent years, her intimate life with her husband has been declining, and the thought of having an affair has started to cross her mind. Around that time, she was dispatched as an executive secretary to a certain company. "I have this image of secretaries getting erotic things done to them by powerful, handsome older men (laughs)." However, Hitomi, who wears a tight skirt that looks like it's about to burst from her plump hips, was assigned to an old man who is about the same age as her father... To escape her boring daily life, she realized she had to take action herself. With that determination, she faced this day. This plump-bottomed housewife, starved for eros, takes on her first public infidelity.
