A married flight attendant named Yuka, working for international flights at Narita Airport, regularly visits a traditional Thai therapy clinic near the airport. She carries herself as a poised and professional stewardess, taking pride in her work. However, the therapist, who appears kind and trustworthy on the surface, is secretly a lewd and unscrupulous man. Under the guise of massage therapy, she ends up experiencing unexpected sexual therapy sessions. The contrast is shocking—while she maintains an elegant and radiant image as a flight attendant in public, behind closed doors she is brought to orgasm repeatedly.
