The film features the beautiful actress Shunka Ayami in three segments with different circumstances and situations.
The first segment is just as the title of the movie suggests; that day Ayami and her male colleague had to stay late at work, so on their way home, they stopped by a fast food restaurant. Nothing would have happened if Ayami hadn’t started drinking. After just a few sips, her mind began to become unstable, she rambled incessantly, and even began to touch her colleague's penis sitting next to her, causing it to harden. Feeling embarrassed in a public place, he led her to the restroom and gave her a lesson she wouldn't forget.
In the second part, Ayami plays a girlfriend whose boyfriend has an accident at work and needs to go to the emergency room. The very next day, she immediately came to take care of him. Here the two could not control their own desires, they secretly had sex even with patients and doctors next to them.
Eventually, Ayami has a boyfriend who is a senior at a university. She is very satisfied because she has a lover who pampers and takes care of her as much as possible, especially in sex. Until one day her boyfriend takes his best friend to the playroom and doesn't hesitate to have sex with her in front of him, causing him to indulge in Ayami's writhing body in lust. After having sex, the boyfriend rolled off to sleep while Ayami still didn't feel satisfied. And of course, his best friend was lucky to be chosen by her to meet his physiological needs.
