Ura eijô: Chijoku no hanabira

裏令嬢 恥辱の花びら (original title)

Synopsis

Arisa, an erotic novelist, is writing in solitude at a remote mountain guesthouse in an attempt to overcome a creative slump. While she continues to write under the watchful gaze of the suspicious caretaker, Mamiya, she is deeply agitated by the relationship between her lover—a publishing company president named Takada—and Anju, a newcomer author with a background in the sex industry. Takada’s stepdaughter, Misaki, is also staying at the guesthouse; the free-spirited young woman seduces Mamiya and engages in shameless, lewd behavior with him.
