REAL-761: Aphrodisiac makes low-libido literary woman beg for cock, Aoi Nakashiro

A man finds a book on aphrodisiacs at a second-hand store and tests it on a woman who reads in the park. Under the effect, she loses control, drips, and begs for sex, then straddles him in a trance. Aoi Nakashiro plays the woman, who is restrained during the scene.
