Being a cabin attendant for a major airline is a profession for high-spec women, often described as "flowers on a high peak." 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. This leads the passenger to enter full "complainer mode," demanding sexual service as compensation. To apologize, she allows him to have her body once, but he becomes emboldened, demanding sex on every flight. Eventually, he even brings a friend along for a threesome. For these passengers, their tickets are premium ones that come with sex services. Because of a single mistake, the beautiful flight attendant's in-flight service now comes with a high-spec pussy as a bonus.
