...An... Insole? What? Whatever could she mean by it? You knew what an insole was, obviously, but how could you 'serve' her as one? This made no sense, none whatsoever. What was this kitsune planning?
Ran took note of your bafflement, and snickered in response.
"Ah, of course, you're not yet aware of what your master is capable of. Mmmm~, I think a little demonstration of my power is in order."
As she said it, Ran extended one of her arms towards you, and opened her palm. Her hand soon began to emit bright, golden light. So bright it was, you had to shield your eyes away from it. Consecutively, you felt some strange power penetrate your body. You weren't sure what it was all about, but since you couldn't do anything at the moment anyways, you've decided to wait it out, and just hope for the best.
Ran's weird little 'ritual' of hers didn't take too long, and once the glowing stopped you were able to open your eyes again. You quickly came to regret that decision.
The change was immediately noticeable. Everything was bigger. The room, the furniture, everything. You've been shrunk down to the size of a tiny toy, half an inch tall at most. That kitsune must've done this, but how!? How did she do it!? How could she do it!? She's... She is... Oh gods...
Your jaw hit the floor the moment your eyes fell upon Ran's colossal form. She was simply gigantic, her size comparable now to that of the Statue of Liberty. She completely dwarfed your small, frail body, easily casting it in the vast shadow of her own, incidental making. At the moment she simply stood there, a menacing grin plastered on her face, as the kitsune was clearly pleased with herself and that 'little' shrinking curse of hers. You could hear the rhythmic drumming of her toes, as she eagerly awaited your panicked reaction to your new circumstances.
Hopefully she was prepared for disappointment.
You tried to move, to run, to scream... but you couldn't. Your mind has been broken, shattered by the impossible predicament that's been so suddenly forced on you. This was simply way too much for a normal guy like you to handle. To the kitsune's mild chagrin, you were simply unable to 'properly' react... So you didn't. You simply stood there still, completely paralyzed. Silent. Unflinching.
Thankfully, Ran knew exactly how to... 'help' you snap out of it.
Without warning, the giantess slammed the heel of her right foot right in front of you, toppling you down on your back, while keeping the rest of her sole elevated over your fallen form. Dizzied and bruised from the impact, your vision cleared to the sight of the vast expanse of rippling, sweltering flesh of her dirtied foot. The kitsune swayed it up and down, constantly exerting her dominance over your pathetic self, as she threatened to crush you into a bloody stain over and over and over again with but a simple downward push of her all-encompassing sole.
Ran's foot already looked pretty imposing back when you were normal sized, but now... It was simply terrifying to behold. Faced with the prospect of a gruesome demise underneath her fetid footstep, you started shouting at the godlike kitsune, begging her for mercy, and pleading for your life. Each whiff of the rancid stench of her sole only made your screaming louder, as did the fear of the giant globes of sweat that rained all around you, pouring from the underside of Ran's swaying footsie.
The cruel titaness let out a haunting cackle the second your squeaky screams reached her vulpine ears. Just like her fellow youkai, Ran draws strength from the fear she instills in humans. The more they fear her, the stronger she becomes. It is thanks to you then, that right now she felt like a goddess, your pitiable wailing more than making up for the effort she put so far into her chores. She had to admit, for a pathetic little speck, you were an astoundingly palatable little morsel.
Alas, though she greatly enjoyed 'teasing' you like this, Ran still had a lot of work ahead of her before she could take her rest. She shrunk you for a reason: to serve as her insole, and hopefully ease some of the burden she, and her feet in particular, have to carry as she goes about her daily routine.
However, as much as she enjoyed the prospect of splitting your mind between two feeble bodies, hopelessly mashed into her almighty feet, as she tramples you over and over and over again, this was far from the limit of her impressive abilities.
She could just as easily turn you into a pair of comfy socks, that would shield her soles from the yet not cleaned floor, while also rubbing off some of the grime already collected on her poor feet.
She could also do something a bit more devious than that, and turn your body into sentient ointment. She would rub you all over her feet to swiftly ease some of her pains, and maybe even save some of you for later use. The kitsune wiggled her toes at the thought of meticulously smearing your sentient, moist form all over and in-between her foul lil'tootsies.
Ah, choices, choices~ In the end, which one will it be?
