Aoi, whose husband was fired from his company and was having trouble making ends meet, came to Ozawa's company for an interview. Aoi is looking for an office job, but Ozawa suggests that she work as her secretary. Her salary is double, but it includes her mistress contract. Even though she is my mistress, I don't have any physical relations with her, only kissing her. She accepts such conditions for the sake of her life. However, kissing Ozawa is as obscene and pleasurable as the copulation between a cock and a pussy.
