ATID-510 Mr. Yuki, a plain librarian, drives a middle-aged man's dick crazy with his abnormal fetish. Rino Yuuki

``I get excited when I smell ink.'' Rino, who works as a librarian, has an unusual sexual habit. She has a tendency to become abnormally excited by the unique smell of ink, and her daily routine is to satisfy her desires alone in the library late at night, surrounded by books. Even though he knows he shouldn't be found by someone, he can't stop himself, and the director, Saeyama, sees the scene.
