That JAV

＜Miyu wants to earn money to please her boyfriend. On the other hand, the manager, who has a fetish for buttocks, has been suffering from the expenses for sex services that promote buttocks. These two situations combine to arrive at a different kind of relationship.... At first it was just about touching butts, but the demands become more extreme with buttocks jobs, then sex, and then Nakadashi. Miyu, too, was unable to refuse as her hourly rate rose with each extreme demand...and her mind was gradually eroded... What am I doing this for?
