He Is My Master (2005)

Two runaways, Izumi Sawatari and her younger sister Mitsuki, are in need of a place to stay. They hear of a young millionaire, Yoshitaka Nakabayashi, who is living all by himself after the death of his parents and who is in need of being looked after. They take the job... then discover that Yoshitake is a shameless pervert who will seize any opportunity to take a look at them in various stages of undress! Izumi is disgusted with Yoshitaka's attitude and does whatever she can to keep him away from her and her sister, but she has no alternative but to stay as his maid and cope with his near-psychopathic fetish for her. And as time passes, her feelings for Yoshitaka start to deepen...
