By day, the lecherous young wife Mei indulges in sex with her casual partner every day. After her husband leaves for work, she can't control her lust and turns on her erotic switch, masturbating. When a delivery man arrives, she pushes him down at the entrance, sniffs his scent, 'You smell of sweat,' and makes him remove his pants, finishing him off with oral sex. Later, when a salesman comes, she forcefully brings him into the room and begs for sex. The salesman is a sadist, and Mei becomes 'obedient,' ending up with him ejaculating inside her. Finally, even the neighbor's casual partner, an older man, joins in for an 'anything goes threesome.' She is made to crawl on all fours with a vibrator tied inside her, and her vagina is cleaned out with water.
