Yuka is a diligent housekeeper. One day, she accidentally sucks her master's crotch with a vacuum cleaner, and in a hurry she takes off his pants and looks after him. From then on, her master makes a series of naughty demands of her. She has to wipe the windows with her breasts, do a parent-child threesome, and then give a blowjob and bukkake to the neighbors. Although she is confused, she is an obedient housekeeper to her master.
