Cosplay Roshutsu Kenkyuukai

Aya, a waitress at a cosplay cafe, receives an E-mail asking her to go to an anime convention, for which she'll be paid as much as she wants, but with one condition: to obey all the males' orders. She ends up going out of curiosity, but the normal perversity among the otaku and her own dirty thoughts turn the photo session into an exhibitionism session. (This OVA is based on a doujin game by Pin-Point.)
