Young art student and aspiring painter Natsuki Oriyama makes her unexpected AV debut! A prize-winning artist in numerous painting contests, she dreams of funding her own solo exhibition through her artwork. However, to raise the money for her dream, she decides to enter the adult video industry. With only one prior sexual experience, she's overwhelmed by the skill of the male performer, writhing in simultaneous surprise and excitement as pleasure consumes her body. Experiencing a piston-like rhythm unlike anything she's had with her boyfriend, she begins craving new forms of ecstasy. Bound to a chair and tormented with sex toys, her pussy gushes with arousal as she convulses into climax. Acknowledging herself as a natural masochist, she dives headfirst into a thrilling new world of pleasure through intense sex.
