The aviation industry has been hit hard by the times. Still, I don't want to quit this job, which has been my dream since I was little. One day, while drinking alone, a middle-aged man talks to him. In exchange for help, why don't you have an adult relationship just once? In order to live, I decided to have a secret meeting at the hotel. However, this man is a true CA maniac. And a pervert whose hobby is to dye it in his own color. Airi who went to be held "only once" falls into a vortex of climax that can not escape.
