Iribitari Gal ni Manko Tsukawasete Morau Hanashi Animation

Synopsis

Hikari Kuroda, a classmate who often comes over to read manga to my house, the house of an inconspicuous "otaku" in class. The reason why Kuroda, who I thought I would never have anything to do with, started hanging out at an otaku's house three months ago was because she asked me if I had all the volumes of a very popular manga, and when I answered that I did... "I'm bored today, so I'll go read it." I don't find it annoying at all that she's started hanging out at my house. Because... She lets me use her pussy instead. (Source: Fanza, translated and edited)
