As she opens her mouth to ask Rita for a change, Leah lets out a deafening wet fart. Unlike the previous ones, it's not a small amount of poop that escapes. Leah gasps as she feels a torrent of feces flood her diaper. The smell wafts from her to Rita quickly.
"Uh oh," Rita says quietly. Her body completely out of her control, Leah can only bend into a squat and pray for it to be over soon. The liquid poop thankfully turns into mush, which turns into a solid. Leah's face turns red with humiliation as a log begins to crown. At this point, she finally has some control back, but is too far gone to stop it. She bends deeper into the squat, grunting, actively pushing the log into her packed diaper. When the log pinches off, it's followed by more mush and liquid poop.
Leah squats there for ten minutes, helplessly filling her diaper with more poop than she ever would have thought she could create at once. Halfway through, she starts to worry that her diaper isn't built for this sort of mess. Her worry is proven when she feels liquid trickling down her leg.
"Well...I guess I should have got you multiple outfits," Rita says quietly, confirming what Leah felt: her diaper is leaking.
When Leah finally finishes, she doesn't bother asking for Rita to take her to the bathroom for a change. Still stunned by the display she just put on, she allows Rita to lead her to a small corner, tucked away but still very much in public.
"All right, I'm going to call it quits, sweetheart," Rita says as she undresses Leah. "You're clearly sick. The park is no place for a poopy tummy girl." Leah doesn't protest over the juvenile language. She merely lays back for her diaper change, staring silently at the sky.
It takes forever for Rita to clean Leah up, and when she's done, she leaves Leah in just her fresh diaper.
"Sorry, I didn't get you any other clothes," Rita says quietly. "I didn't think you'd have a blowout like that."
"Me neither," Leah mumbles. Rita puts the pacifier in her mouth, and Leah sucks on it instinctively. Not only will it help with her disguise as a toddler, but it's providing her some much needed comfort.
Rita picks Leah up and makes a beeline for the park entrance. No one bats an eye as they pass, seeing only a woman carrying a toddler girl. When they get to the car, Rita buckles Leah into a back seat. She strokes Leah's hair.
"Okay, we're going to go get you..."
