Whenever Mio Kimijima, an elite office lady and sales manager, gets stressed, she releases it by engaging in exhibitionism. The pleasure of exhibitionism gradually becomes more extreme as she seeks further stimulation. A cleaning worker at the company secretly films her doing so. She is blackmailed with the footage, forced to have sex in the office, and then trained as an exhibitionist. She kneels naked in the bathroom, masturbates naked in front of customers at the library, induces a molester on the train, and has a huge load of semen splashed on her at an offline meetup... Mio exposes her shame and shamelessness and drowns in the bottomless swamp of perverted pleasure. This is the whole story of how this elite office lady falls to the depths of desire!
