All roles are performed by adults. Urara prefers books to romance or fashion, but an erotic novel she secretly reads in her father's study awakens her fascination with public nudity. Stripping off her uniform in an empty classroom becomes a daily habit, and fantasies of being seen leave her pussy wet. Once she is caught, the humiliation feels even better: she sucks several strangers' cocks, squirts heavily in public, then stands naked before her classmates and confesses that she is an exhibitionist, writhing to a masochistic orgasm under their leering stares.
