She uses it on her shoes.

She grabbed a few Upgraders and click-clacked her way to the bench,

"Now, how do I use them? They won't fit in the keyhole."

The girl noticed that the front end of the cylinder was flexible and figured that she could apply it to any part of her outfit. She took one of the Upgraders and was about to find a place on the swimsuit to use it, but suddenly stared at her shoes.

They were undeniably beautiful, but they were poisoning the very process of walking for long enough.

"Stupid heels, I'm so fucking done with you." — she missed wearing her usual sneakers so much that the sight of these terribly impractical shoes still stuck on her feet made her very angry.

"You know what? You go first."

Jen held an Upgrader against her right ankle. A green rectangle started glowing on the side of the device, and it started pumping the substance right into the strap. When it became empty, it fell off on its own.

As the keyhole stayed in place, Jen hurried to add a second device to the left ankle. When it did not have any immediate effect as well, her patience was gone.

"I'll use as many as needed to get rid of you, you stubborn fucking little white shits!" — she yelled and put two more Upgraders at the same area.

As soon as she did that, she noticed that the shoes' leather surface began extending both down and up from the ankle straps! Anger replaced by fear, she tried to pull the second pair of Upgraders away to stop them from pumping more cement-like substance into her shoes, but they appeared to be vacuum-sealed and detached only when they were done with that.

White leather flowed over Jen's feet, turning shoes into boots. When this was done, the material started conquering her whole lower legs with more **** than in the beginning. The girl also noticed that the heel and platform was quickly becoming higher and thinner. The thought of having an even worse time walking made her burst in tears, and she turned away, unable to bear helplessly watching the upgrading of her footwear.

The boots rose to Jen's knees, while the ankle strap developed strange metal rings from its sides. Soon they were repeated at the knees, and the leather kept climbing upwards. The girl moved her arms away from her thighs to not get them sealed underneath by accident, and adjusted her leg position. When she heard two quiet clicks, she reluctantly looked down at what was happening, and saw that the rings on the inner sides of her ankles and her knees somehow linked together.

"No... I can't even walk anymore at all!"

Gorgeous genuine leather went up Jen's thighs and joined together at her crotch before extending further up her hips, covering the steel swimsuit and hiding her pussy under another layer of smooth high-quality material. Another pair of rings grew from her hips, and the growth stopped a few inches lower than her waist.

Jen tried pulling down the waist high boots, but the top line was completely unyielding. As a finishing touch, the whole ensemble obtained the glossy coating that the original shoes had.

In the meantime, the boots' toeboxes shrunk to the point when only Jen's toes could be there, while the rest of her feet were arched at insane angle. The needle-thin heel height exceeded 10 inches by now, while the 3-inch high platform was barely wider than the heel at its bottom part. There was one keyhole per ankle strap before, now there were five.

Two pairs of linked rings left maximum circumference of 5 inches. Jen could not separate her ankles and knees further than that, despite her increasingly fierce attempts.

"Why... WHY?! FUCK THESE UPGRADERS! FUCK THIS PLACE! LET ME OUT!"

She jumped up and held onto the closest shelf, starting to move towards the exit as quickly as possible. Needless to say, she tripped on her third step. The shelf she was hanging on was not accustomed to such overload and collapsed onto her.

When Jen managed to crawl onto it to escape the tiles, the hyperventilating girl noticed at least five more Upgraders doing their job on both her 'boots' and her 'swimsuit' after she dropped a shelf full of them over herself. It was too much for her, and she fainted.

As she lied still, evil devices detached and rolled down to the floor. Steel of her swimsuit moved out to encase her head, leaving only two nostrils for breathing, as the leather rose all the way up to her shoulders, buckling her hands to her hips with rings in the process...

***

Jen awoke, but could not see anything or even turn her head. The shell that contained her head was made of steel, and she instinctively reached to touch it with her leather-clad hands, only to discover that they were attached to her hips.

She quickly found out that she was in some kind of plastic cell, and started banging and kicking against it. After approximately an hour of fighting, she ran out of her raging fury and probed the walls with her gloved fingers. There was no damage.

Jen was alone. Even her second voice abandoned her. In despair, she started crying again, right into her new steel helmet.
