Elegant flight attendant Mizuhata Asami looks nothing like an extreme masochist, yet her sex drive is so intense that she masturbates in the aircraft restroom. She says a bar manager trained her while she was an adult student working part-time, and even after becoming a successful flight attendant she could never forget the thrill. Unable to suppress the growing desire, she applies to appear and publicly begs the group to put her through exhaustive humiliation and BDSM training.
