The main character is an ordinary young bachelor in his thirties who leads an ordinary unremarkable life. One day, while walking late at night, he stumbled into an alleyway and stumbled upon a strange structure. Inside, waiting for him were two female gyaru students, blond Ami and dark-haired Nana with incredibly seductive bodies. For a certain amount of money, they are ready to fulfill his every sexual desire... Ami or Itano Atsumi is a bright friendly person who loves to wear bright or even flamboyant clothes typical of a gyar. She is very popular with her peers and is oddly enough smart and intelligent, as well as very athletic. However, what she loves most in life is sex and the rustling of bills. Perhaps that is why she became a prostitute. Nana or Nana Celis - A very nice and serious girl. Because of her elegant appearance and hairstyle with long straight dark hair, she is perceived as a girl of high society and noble blood. However, this is all just on the outside, but inside she is a sex-crazed pervert. Nana loves armchair sex, deep hickey kisses, and of course blowjobs without a condom for her clients.
