"Finish going potty, then we'll get you into some diapers," Tonya says, setting Leah down. Leah's bladder immediately lets loose again. She feels the poop she stopped earlier starting again. "You kinda need them now," Tonya finishes. Leah glares at her, though she's not sure how well the expression comes across. She can tell that she's scrunching up her face with effort as she pushes more poop into her underwear.
"Why did you say it like that?" Leah demands. "You just doomed me to be in diapers, even without someone accidentally saying a word that makes me go!" She grunts loudly. The log pinches off and is followed by a series of farts, accompanied by mushy poop. Tonya's eyes widen.
"I'm sorry, I wasn't thinking about it!" Tonya says. "Look, we'll- we're going to figure it out, okay? If it doesn't wear off, I can just say the command that makes you stop."
"Yeah..." Leah grunts again, pushing out one last load of poop. "Ugh. I know I need to be changed, but I don't want to go out there right now. Not like this."
"That's perfectly fine. If you wait in the stall and then let me in when I get back, we can get you changed," Tonya says. Leah nods. She walks into the large handicapped stall and closes the door, locking it, then sits down on the floor to wait for Tonya to come back. As she waits, she can feel another wet accident, but thankfully not another messy one. But given that she hasn't gotten any sort of new trigger, it seems like she's right. Tonya accidentally commanded her to need diapers, not just have an accident when someone says the wrong word or phrase.
Thankfully, Tonya comes back in what seems like record time, carrying a pack of diapers, baby wipes, and a new toddler outfit. This one is distinctly more immature than the other one, being a frilly light blue sundress, with a matching diaper cover. Tonya opens her mouth to explain, but Leah shakes her head.
"No, don't tell me your logic, because you might make something come true that wasn't already true."
"All right. Now, uh, let me change you, and then we can figure out our next step," Tonya says. Leah feels herself freeze into place. She's unable to do anything other than behave perfectly for her change. She can't even wince at the cold diaper wipes, though she wants to. Soon, Leah is diapered and dressed. "Come on, let's get out of here."
Again unable to control herself, Leah follows Tonya out of the bathroom. The diaper crinkles with every step, thick and fluffy, but Leah's able to avoid toddling around. At least, for now.
Once they're back in the main part of the store, Tonya turns to Leah.
"Okay, let's go..." Tonya starts. There's a loud hiss from Leah as she wets herself. "Oh, no! Did I cause that?"
