Shrunken OC belongs to https://www.deviantart.com/gigasoph, who I've been done up a few pieces for.

Soph had been taking an evening stroll, walking by a schoolyard fence when a kaleidoscope of colored light suddenly burst around her, and her vision went black. She awoke to a splitting headache, and shocked as she looked around to see some kind of gigantic swamp all around her. Everything from the trees to the grass was gigantic, she felt like a puny bug lost in the world of giants. That gut feeling would be confirmed in the next few minutes as the ground suddenly shook with several thundering booms, and she watched in mute terror as a gigantic girl suddenly pounded into view. Her hair and clothes were disheveled, but all Soph could drink in at the moment was how terrifyingly massive the girl was, gazing up in shock right up to the moment Anne's dirty sock slammed on top of her. She stuck fast to the grimy fabric as the giant girl continued rushing along, completely unaware of her shrunken passenger that she was pounding under foot. Soph spent days living on the bottom of Anne's unwashed sock, slurping up her sweat to survive despite the rank taste. It wasn't until Anne had finally reached civilization that Soph came loose, being given just enough time to celebrate before being stomped flat by an even grosser foot. This time however, she heard an immediate muffled "Huh?", followed by the foot she was stuck to being lifted up and held.

Maddie looked at the strange insect stuck to her sole, which looked completely unlike anything she'd ever seen before. It appeared bipedal... and it was wearing clothes? Her natural instinct was to lick it off her foot, but it's curious appearance stopped her from wasting it as a snack. When she made out the pleas for help that the tiny thing was squeaking at her she was especially thankful for her restraint, this was the coolest test subject she'd ever found! She immediately began rushing back home, not even bothering to pluck Soph off her foot before doing so. The tiny was trampled yet again, but she was sinking even deeper into the slimy, spongy sole of this frog girl than she ever had under Anne... 

Maddie rushed into her room and immediately snatched up her research tome, before hopping onto her stool and kicking up her feet. She relaxed comfortably while she brainstormed all the experiments she could cook up for this strange creature she'd captured, all the while Soph was embedded helplessly in her sweaty sole. An entire hour passed with Maddie jotting down ideas before Soph managed to pry her head free, her throat hoarse from the lack of air. She was already used to the degrading aspects of her new size, and didn't hesitate to start lapping up the mixture of slime and sweat that coated her new owners massive foot. Maddie noticed the small licking sensation after a few minutes, and put her book aside as she curiously observed the tiny being worshipping her pudgy stomper. "Huh... I still have a lot of tests to run with you, but once I'm done documenting your species you could make a pretty neat foot pet. I wonder if I could even get you to lick other parts of my body, there's certainly more than just my feet that need a wash..."

Maddie's heart dropped at the frog witch's musings, which were making her enslavement to giant amphibian sound a lot more permanent than she hoped. Rather than stop in defiance though she actually picked up the pace with her tongue, too terrified at the thought of making this giantess mad even at the risk of becoming some sort of plaything for her. Maddie kicked back even more lazily as Soph did her work, gagging on the rancid taste of Maddie's foot grime even as she slurped down more. This was seeming like her new lot in life, so the sooner she got used to the taste the better she supposed...
