Iribitari Gal ni Manko Tsukawasete Morau Hanashi Episode 4

At the house of the inconspicuous “otaku” classmate who nobody really notices in class, Kuroda Hikari regularly comes over to read his manga. One day, Hikari suddenly brings along the scary/deliquent classmate, Nishizono Ria. She told me: Do to me the same thing you always do with Hikari. At first the otaku is so nervous he can’t even process what’s happening, but little by little his excitement starts building up inside him. Only for Nishizono to coldly declare, “I didn’t get anything out of it,” and write him off completely… “N-Nishizono-san…! I-I can still keep going!” Now, the otaku’s complete loss of control begins.
