Uchi no Maid ni Seiheki Yugameraremashita

Son of a noble family, Tsubasa Ichijou has a problem. He can only get pleasure from male maids. Azusa Kurokawa, a high school teacher and Tsubasa's exclusive maid, also has a problem. Even though he was nurtured into a full on pain-lover by the young sadistic tyrant that was Tsubasa, he, in turn, brought Tsubasa up to be a gentleman who just won't seem to assault him... As usual, Azusa is getting both annoyed and aroused by Tsubasa's words and actions when he gets an idea!
