Giantess Ivory discovered that her sweaty feet work as a shrinking potion. You just have to worship her sweaty feet and the vapors will shrink you a little more each time. She takes her tiny and puts him into her smelly, sweaty flats. He is desperate to shrink even smaller and he worships his way around the inside of her shoe and soles. Her thick wrinkles surround his body and the foot funk starts to seep into every centimeter of him. Her foot vapor is taking effect and she dumps a slightly smaller tiny out of her shoe. Her foot funk has worked! He shrunk a bit more for her. She puts him to work in this shrunken state. She likes him even more the smaller he is. She can keep him safe between her toes and wrinkles, instead of feeling like she has a pebble stuck in her shoe. She is so happy she shrunk him and tells him how he will be staying in her shoe more often.
