Witch Shrink n Step
You were in the wrong place at the wrong time, and you were captured by a witch who just wanted a tiny man to step on. You awaken in her lair and she looms over you. At first you think it a trick of the eyes until you realize you are shrunk down. She laughs and asks you if you notice anything else strange about your body. You don't.. so se explains you are now made of very stretchy rubber. She intends to use you like a stress ball for her feet. Human men made of flesh often break so fast she never feels fully satisfied although the crunching and squelching is nice. But she wanted you to last. So while you will feel every movement and step onto you, you will pop back into shape for her to reuse over and over. She tried out every part of her foot- heel, arch, toes and all. She smears you across the floor and revels in how fun it is for your body to be moldable. Your eyes and body being ground down under her so you look like a blob before retaining your man-shape again. She looms over you, tall and enjoying the power of you being so small and defenseless. She is going to see just how much torment you can take before your mind gives in an you fade out for a while. After all, you feel every second of the activities she is doing, you just aren't breaking. All the same sensations and none of the sweet release because you are now her eternal stepping toy to use until se decides otherwise!
