To clear her fiancé of wrongdoing before their wedding, beautiful secretary Kiho Kanematsu becomes the personal assistant to a disgusting, slug-like company president. Instead of salvation, she is forced into a nightmare of foul breath, body odor, and filthy saliva as he declares her his licking slave. She initially gags while his rough tongue crawls over her entire body, but relentless licking and intimate caresses gradually turn revulsion into irresistible pleasure. Her reason finally collapses, and she begs him to lick her more, completely conquered into shameless obedience in this depraved training-and-kissing cuckolding story.
