Saki Hatsumi enjoys playing tennis with her husband. One day, a perverted man breaks into her home and rapes her, then blackmails her with photos, forcing her to obey his demands. On the street, her clothes are stripped off, exposing her breasts and ass to passersby. The pervert's desires grow increasingly intense, forcing her into strip tennis and outdoor naked sex. Initially resisting, Saki gradually awakens to the pleasure of exposure, submitting to ever more extreme acts of humiliation and becoming deeper entangled in his depravity.
