Persona 4 Regression ULTIMAX! Part 7 (Patreon)

Chie knew she should have expected the nursery’s newest arrival. Ms. Nami had mentioned more friends coming, Yukiko was already here and they’d all been together in the food court that day so of course she’d been affected too. All of that didn’t stop the exclamation of her friend's name when she saw her. “Rise!?” she said, staring at her friend in disbelief.

The peppy idol skipped into the center of the room and passed Ms. Nami briefly as the caretaker went to speak with her chaperone. She was wearing a short yellow sundress that differed from Chie’s and Yukiko’s outfits in one key way. Hers was without the snap crotch cover that theirs both had, giving whoever was looking at her a clear view of the rotund exterior the padding that peeked out below the hemline of the skirt.

Rise stopped in the middle of the room, turning gracefully on her feet to find who had addressed her. When she saw Chie sitting on the ground she bent over to bring her face down to the tomboy’s level. “Oh, hi Chie-chan!” she said enthusiastically, “Why’re you on the floor?”

Almost immediately after asking the question, Rise’s nose wrinkled and she made a face, causing a wave of self-consciousness to wash over Chie. Her next statement didn’t make it any better. “Ewww, you’re all stinky!”

The tomboy’s immediate reaction was to blush but she quickly grew defensive about her mushy state. “I can’t help it!” she protested, pushing herself up from the floor, “And you’re wearing a diaper too, I bet you’d do the same.”

In a very snotty tone Rise said, “Nuh-uh,” while crossing her arms proudly “I only have wet accidents. I know how to use the potty like a big girl, that’s why I’m not wearing baby clothes like you and Yuki-chan.”

Chie was flabbergasted, not only at the superior tone her friend was displaying but at her actual jealousy. “I’m a big girl!” she thought, “I bet if I was even given the option of using a toilet I could. Also, who does she think she is? A diaper on obvious display like that  is totally babyish!”

While she might have been fuming internally, Chie didn’t feel like she had a good comeback to say directly to the snooty brat in front of her. The very full diaper sagging against the cradle of her onesie’s bottom was far too much of a distraction.

She couldn’t find a single way to stand comfortably.

Before, the bulk of the diaper had given her a slight waddle, altering her gait because of its thickness. Now she had to contend with the revulsion of squishing the mush of her own waste against her thighs. She was still practically squatting, giving Rise the advantage of height as well as being the only one with a clean diaper.

Before another snarky remark could be fired at Chie the tense standoff between the pair was interrupted by the daycare’s supervisor, who approached them after having finished talking to the woman who’d dropped Rise off.

“Now,” the silver-haired daycare attendant said with a clap of her hands, “Rise, why don’t you go play with Yukiko while I deal with Miss Stinkypants.” The ex-idol threw a hand up to her lips and giggled, nodding gleefully. “Yes Ms. Nami.” she said, trotting off happily in the other direction.

This left Chie with the stern-faced caretaker who lowered her red eyes to look her mush-tushed charge up and down a few times. “Don’t think I’m forgetting about the no-no word you said a minute ago,” she scolded, "You’ve earned yourself ten minutes of corner time for that one.”

“You’re going to make me stay in this!?” Chie asked, indicating the very full padding around her waist.

“That’s right and I’ll change you after. You need to accept the consequences of your actions.” She took Chie by the shoulders, displaying her impressive authority with her height. Chie hadn’t realized before now but due to her current lowered stance, Ms. Nami had almost half a foot in height on her.

She was brought to one corner of the room and turned to stare directly into the corner. “Ten minutes, Miss Satonaka, and I don’t want to hear a peep. Once that’s done you can come out and I’ll help you change.”

It would have been easy for Chie to turn away from the corner and walk away. She was a grown woman and didn’t need to put up with this treatment but even with that knowledge she stayed put. Something was compelling her to obey the commands of the silver-haired caretaker and she had no way to explain it.

For ten whole minutes Chie shifted uncomfortably, bothered by the now lukewarm pile of gunk weighing down the back of her diaper. The tapes of the garment strained due to the weight but never gave up. When her squat became too exhausting to maintain, Chie righted herself, standing up straight and compressing her accident between her thighs in a most unpleasant squish.

At this she winced, almost calling out in disgust but just barely managing to hold it in. The whole experience was made worse by the snarky comments coming from behind her. She could hear the sounds of play between Rise and Yukiko interspersed with comments about the “smelly corner” or how “she and Yukiko would never get sent to the naughty corner, would they?” Chie’s urge to fire back a retort grew but she held it at bay with the knowledge that any retort would add more and more time to her torturous wait for a diaper change.

After what felt like an eternity Chie finally felt the tap of Ms. Nami’s finger on her shoulder. “I hope you learned your lesson from this.” she said, taking Chie’s hand in hers. “Why don’t we get you changed?"

The tomboy followed obediently, thrilled at the promise of release from her soiled undergarments. They just had one quick stop before the table—the potty charts.

Ms. Nami grabbed some stickers from a tote hanging below the charts, placing both a raindrop and a lightning bolt on Chie’s chart for the day. Chie groaned, already bothered by the ever-present reminder that she couldn’t keep her pants clean.
