"Alright Madison, I'll make you normal." You tell her.
Her sobbing stops. She loops up at you with hope.
"...on one condition." You add.
She nods.
"Whatever it is, I'll do it!"
"Good." You say, getting up and heading for her dresser drawers.
"All you have to do, is go out with me to the store."
"...that's all?" She asks, hopefully.
"Well, mostly." You say, picking out a pair of shorts for her to wear. You kneel down by her and step her into the shorts, lift them up and button them.
"H-hey, I need to...clean up first." She frets.
"Oh, well, we're not doing that here." You say, getting up and assembling your things.
"...what?" She starts to get worried, turning around to follow you.
"We're doing it at the store."
"W-wait! Why AT the store???" She starts to freak out.
"Well, we can't very well change you here. We haven't the wipes or powder! We'll have to go to the store to buy them, and we wouldn't want to waste any more time before getting you clean." You head out her door.
"Bbbbbbbut!!" She puts a pin in her protesting, not wanting to discuss this next to her family. She reluctantly follows you down the steps, cringing at the sensation of her mess shifting around in her diaper as she moves. She waits until you are both outside to resume her questioning.
"But but but! You said I wasn't gonna have to wear diapers anymore!"
"Don't worry, you won't." You say, you and her getting into the car. "Once we get home, I'll undo everything and you'll be 100% back to normal."
"But!!!" She slams her hand into the seat, as she reluctantly buckles up.
"Hey Maddie, if you complain too much, I might change my mind back, and then some."
Madison is about to go off on you, but barely keeps it bottled up. She catches her breath.
