A cleaning lady is hired to clean up a desperate man's home. The desperate man takes an interest towards the cleaning lady: her friendly behavior, her beautiful smile, and her big fat ass. Her ass is so big that her jeans can't hold up. They have to sag. And sag they do to reveal her rather slutty underwear. The sight of the underwear triggers the desperate man into visioning and eventually committing to having sex with her, no matter the cost. The only problem is she doesn't want to, particularly because she's engaged. (This is a more compelling edit of the real teaser and plot. BETTER NOT TO UNDERSTAND JAPANESE.)
