Cosplay Roshutsu Kenkyuukai

Using a doujin game by Pin-Point.

Aya, a waitress at the cosplay cafe, receives an E-mail asking her to visit an anime convention, in which she'll get paid around she would like, however with one condition: to obey each of the males' orders. She winds up moving away from curiosity, but the normal perversity on the list of otaku and her dirty thoughts turn the photo session into an exhibitionism session.
