Amane Uran, a married woman with a scat fetish, works as an illegal home helper to earn extra cash while her husband is away. She visits clients' homes dressed provocatively, performing housework and sexual services. One day, she is caught on camera by a neighbor who then forces her into a high-paying helper contract as a settlement. Teaming up with her colleague Aragaki Kotori, they begin a stench-filled service involving intense odor torture. They expose clients to the smells of toe sweat, saliva, anal odor, urine, and feces, then obsessively lick their faces with foul, tainted tongues. An abnormal scandal unfolds as the men become dominated by the odors and addicted to their body stenches.
