A plain-looking, bespectacled bookstore clerk, speaking in a low, lewd voice using obscene language learned from erotic books, is a silent, demure, and alluring woman. (MIDA-406)

I'm the manager of a bookstore. A new part-time worker, Sakura-chan, recently joined. Although she looks plain, I know she secretly reads erotic books in the sales area and even masturbates in the restroom. "She's definitely a slut," I half-forced her to undress at the back. Her breasts are unbelievably huge—a G-cup! Because nobody pays attention to her, she's willing to do anything. And she seems to have learned a lot from those erotic books, always whispering lewd things (laughs) like, "I want my filthy cunt!" Such a contrast!! Every time our shifts overlap, I want to rub her breasts and have sex!! Even when we call Nakama, she's all smiles during a threesome! Plain-looking girls with great figures are definitely the best!!
