Leah 'eep'ed as Tonya patted her squishy butt.
"Hmmm, you might be a little young for pull-ups. We should probably get you some diapers." Tonya whispered to herself. Leah jumped away from Tonya, but could already feel her potty training deteriorating, forcing her into a potty dance.
"T-Tonya, what the hell?!"
Tonya blinked rapidly before blushing, looking confused herself.
"I don't...know why I did that."
"U-Undo the trigger, I'm about to burst!"
"Oh, then let's get you to the potty quick!" Tonya answered, picking Leah up with another 'eep' and quickly getting her clothes off.
"W-Wait, no, just say the thing! Tonya!" But her overalls were already unsnapped, and she couldn't hold it much longer, so she allowed Tonya to pull down her messy underwear and plop her onto a toilet. She sighed in relief as her bladder released, getting a clap from Tonya.
"Good job! You made it!"
"Tonya, what the fuck was that?"
"Hey, watch the-" She blinked, then blushed again, "I...I just did that. Why did I do that?"
"You made me too young for pull-ups! Just say I'm a big girl!"
"R-Right, right! You're a...a..." Tonya looked to be struggling to speak before she finally burst out with, "You're such a good girl!"
She grabbed her mouth, and Leah was starting to get very concerned.
"Tonya...why didn't you say it?"
"I don't think I can?"
"What do you MEAN you don't think you can?"
"I mean...I can't bring myself to say it. Whenever I think of you, I can't even think of the word b- bi- big g-g-good girl!" She once again covered her mouth, "Leah, you mentioned a weird T.V. Aisle, right?"
"Oh no."
"I think I went through it too."
"Tonya, what did you tell them?"
"They were asking me questions, and I think I said something about..." She winced, "Being...a better...babysitter?"
Leah looked on in horror. Of all the things, they were both hypnotized to fit into each other perfectly in the worst ways.
"So what, now you feel compelled to...babysit me?"
"You just look so young, my brain refuses to see you as anything other than a toddler. It's like I NEED to take care of you!"
"Wait, d-don't-" But it was too late, already Leah could feel the lightheadedness returning, "Jus...be a nowmal giwl? Ah no."
"I-I don't think this is triggered. It feels innate. It's like I..."
