A Tale of Two Costumes - Part 2 (Patreon)

"What did you do?!" Cheshire gasped, looking down at herself, able now to clearly see her panties beneath her skirt, even from the front... If you could even really call them panties anymore. It was indisputably a diaper, thick, crinkly, and covered in blue teddy bears.

"Fixing things," the woman replied. "It isn't nearly as offensive now... After all, nobody can be mad at your for being so determined to show off your underthings if you need to have them checked regularly, to make sure you don't get a rash."

"B-But I don't!" Cheshire insisted. "I don't need to be checked... I'm not a baby! I can't walk around like this... I'm an adult!" She started to reach for the tapes, only to remember what had started all of this; if the woman had been right about how revealing her dress was, she didn't exactly want to run around with nothing under it, either. That really would be inappropriate...

"You... You change them back right now!" she said. She had no idea how the woman could have done it in the first place, but surely if she could do that, she could reverse it. "Right now!" she stomped her foot when the woman didn't move.

"I think this suits you much better," the woman replied.

"No, it does not!" Cheshire disagreed vehemently. "I don't know who you are, but if you don't undo this right now, I will..." she advanced on the woman, not sure exactly what she was going to do; she didn't have a chance to figure it out, either, as she tripped over a tree root she'd been certain wasn't there a moment ago, falling to the ground.

"What are you going to do, little girl?" the woman asked, stepping closer. Cheshire tried to scramble to her feet, only managing to sit up instead, her legs feeling extra long and clumsy beneath her. "You can't even keep your pants dry, what do you think you're going to do to a grown-up like me?"

"I can, too!" Cheshire pouted. "I do it all the time, which is why I don't need..."

She paused, wiggling on her backside, frowning. Something felt different... Warmer, squishier... She knew this wasn't the right time, yet she couldn't help glancing down at herself, trying to figure out what could possibly be going on. Even once she'd seen it, she couldn't believe it, her stomach falling as she pressed a hand to her diaper, feeling the wet padding there, starting to bunch up together as it absorbed her... liquid...

"Oh, so you do this all the time?" the woman raised her eyebrow.

"N-No," Cheshire shook her head. "Not this, I..."

"Well, you clearly don't have any changes with you," the woman said. "And I wasn't expecting to run across a baby off by herself... You'd better come with me." She reached down, grabbing Cheshire's hand and pulling her to her feet, still pawing worriedly at her diaper, trying to figure out how it could have happened. "Sorry, but I think your trick or treating is done for this year."
