Flight attendants for major airlines are hired only from high-spec women, making it a profession known as the "unreachable flower." Among them, Ms. Nanatsumori is rumored to be exceptionally beautiful. While her customer service and attitude are outstanding, she makes her first mistake (accidentally breaking a passenger's luggage), which leads a passenger in full "complainer mode" to demand sexual service as compensation. Intending only as an apology, she allows her body to be taken once, but the passenger gets carried away and demands sex on every flight. Eventually, he even brings a friend along for a threesome. Their tickets are now premium ones that come with sex services. The in-flight service of this beautiful flight attendant, who gave up her body due to a single mistake, now comes with a high-spec pussy as a bonus.
