Giantess Ivorys annoying brother-in-law walks in on her foot training a shrunken slave. Ivory can't stand him and tricks him into making a bet with her that he can last as a tiny. She shrinks him and begins using him as a foot slave, showing him how hard it truly is. She puts the tinies to work against each other making them compete to clean between her toes. At this size, they have no choice. Her big toe and second toe hold them in tight while they slurp buckets of sweat off her perfect feet. She laughs and taunts her in-law endlessly, telling him her other slave wins and giving him a break in her smelly flats. Ivory loves having her in-law shrunken and in full control. She doesn't even want to un-shrink him now. She laughs about how she will probably never grow him back and makes him keep worshiping her feet. At this size, he realizes that he has no control anymore. He is now just something for Ivory to play with. He belongs to her and must get used to the loss of control. He cant believe how stupid he was to let her shrink him.
