The film features the beautiful actress Shunka Ayami in three segments with different circumstances and situations.
The first segment is just like the movie title; that day, Ayami and her male colleague had to stay late for work, so on their way home, they stopped by a fast-food restaurant. Nothing would have happened if Ayami hadn’t had a drink. After just a few sips, her mind started to become unstable, she began to ramble incessantly, and even touched her colleague's penis sitting next to her, causing it to become erect. Feeling embarrassed in a crowded place, he took her to the restroom and taught her a memorable lesson.
In the second part, Ayami plays the role of a girlfriend whose boyfriend has an accident at work and needs to go to the hospital. The 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.
