Cassandra was used to most of the downsides her vigilante lifestyle came with, from lack of sleep to aching all over, but she had never been as annoyed with her feet as she was tonight. They would always be sore from a hard night of crime fighting, but the itchiness that had plagued them for the last few days was far from typical. It had all started when she went to investigate a chemical factory that had reported a break-in, when she accidentally stepped in a puddle of spilled chemicals that started eating through her foot-wraps. She quickly pulled her compromised footwear off and thankfully found her soles unharmed, but then made the mistake of her continuing her search of the factory barefoot. She of course took great care not to step in anymore spilled chemicals, but the longer she paced around the facility the more irritated her feet seemed to get. She had assumed it was just from the grime building up and simply decided to go grab a shower after she was done, which she soon was as the intruders seemed to be long gone from the factory.
To her confusion and anger however, no matter how much she washed or scrubbed her soles the feeling refused to go away. A closer inspection of her feet revealed several tiny black spots that had appeared on her soles, which refused to budge no matter how she scratched and picked at them. She ruefully accepted that this had to be some kind of medical condition she had developed from the chemical she stepped in, and decided to pay the turtles a visit in the morning to see if they could help. One night of difficult sleep later, she headed to the sewer after first picking up a sample of the spill she had blundered into, which Donatello quickly analysed. The mixture surprisingly turned out to be completely benign, his best guess was that she just had some kind of allergic reaction to it. All he had to offer his short-tempered friend was some pills that should have helped tone down the itching, and the advice to just wait out the reaction. Almost a week later, the spots on her feet remained unchanged. The pills didn't seem to help with anything, and Cassandra has been slowly going mad from the endless irritation of her soles. She had been close to storming back into the lair and smashing things until Donny gave her something that actually worked, when she accidentally found a solution on her own.
She had taken the last few days off since she didn't fancy fighting criminals in her condition, and spent most of them angrily curled up in bed rather than walking around. She therefore hadn't put much pressure onto her feet since this whole thing had started, not until she had a rage-fuelled tantrum after yet another night of restless sleep. She furiously jumped and stomped on the ground, and launched powerful kicks against her walls and furniture. Halfway through her rampage however she suddenly realised that her feet felt normal at last, and even remained that way when she slowly came to a stop and sank onto the couch. Her mind raced even as she indulged in her long-awaited relief, maintaining her focus on her soles as she finally relaxed. Over an hour passed before she felt the frustrating feeling start to kick up yet again, but it only took a single strong stomp to make it cease once more. Several hours passed before the itch dared to try again, Cassandra once again shut it down with a gleeful series of hops. A smug grin was plastered on her face at finally finding a solution to her problem, and she happily donned her fighting outfit again to officially end her vacation. Only an hour into the night however she realised that her foot-wraps seemed to be cushioning her feet too much for the method to work, so she discarded them without a second thought and continued barefoot. From there on out she barely felt a thing as she unleashed a pent-up string of ass-kicking's, the criminals of New York finding her an even more frightening foe than usual. She actually started to relish the rare occurrences where the itch would start again, since it almost felt like another villain she got to pound underfoot...
Meanwhile, the group of thieves that had accidentally spilled a shrinking serum onto themselves were in more torment than ever. Ever since this oddly-dressed giantess had stepped on them while tramping about the factory, they had been completely stuck to her filthy, sweaty sole. A strange reaction between the shrinking serum and the chemical she just stepped in had chemically bound them to her flesh, they were nearly impossible to remove anymore. Every step she took painfully crushed the group of tinies beneath her weight, but they strangely failed to explode into goo like their bug-like size would suggest. Seemingly another side-effect of the chemical cocktail they were exposed to, but their invulnerability was more of a curse with how hellish their new environment was. Constantly ground and scraped across the disgusting ground, forced to huff the pungent odour of Cassandra's weary feet, and endlessly marinated in her salty foot sweat. They struggled with all their might as the brutal days went by to no avail, constantly praying for an end to their torture. All their efforts did however, was make things worse. The angry goddess they were plastered to soon saw fit to punish them for their frantic squirming, and slowly trained them like pets to remain still or face her crushing wrath. They had barely been imprisoned on her foot for a week but their grip on reality was already starting to slip, their anger and indignation towards their tormentor slowly turning towards worship whenever she didn't treat them quite as harshly. With enough time trapped under her mind-melting tread, they would eventually even view her stomping sessions as a gift from their perfect goddess, planting grateful kisses on her sole as she battered them underfoot. Cassandra would never learn about her minuscule devotees, and would even forget about the itchy marks on her feet from time to time. Their lives however were completely dominated by her presence, but after many months of her "tough love", they wouldn't have it any other way...
