Cheating the Cycle of Life- A Padded Pony Collab

Rarity was fully aware that, by deciding to stay at Twilight's side in her strangest hour of need, she was going to live with Twilight's mother, go to Magic Kindergarten with Twilight and, as such, be treated like a foal.

However, after she had presented herself to her and Twilight's new little classmates in a way that caused general giggling in the young audience, Rarity had Twilight explain the rules to her, and she wasn't very pleased.

"You mean that I cannot go to the little fillies' room and that I have to use the diaper?" Rarity pointed at the black sector of the carboard clock, then she pointed cringing at her light pink frilly diaper, making it crinkle and makign the white smock swish around a little, "That's very unladylike!"

"Actually, no," Twiligth said, pretendign to adjust a couple of invisible glasses resting on her muzzle and shifting aroudn in her purple-ish diaper "it just means that you cannot access to it until the teachers decide to bring all the foals there. It's for precaution, you know."

"But we are adults," Rarity said "we can do it safely.I'm sure that the teachers would let us access to the bathroom beofre the little ones." Twilight sighed and shrugged.

"Sadly, we need to abide to the same rules of our classmates. Besides, we are big girls, we can keep it, right?"

Rarity nodded and sighed. "Right, right."

Twilight then started to look around for opportunities to play with her classmates, and Rarity did the same, albeit separated from Twilight.

Time went on. Twilight had dealt with Hard Time's bullying of Lex Populi, while Rarity had found something to do, by playing with dress-up dolls with Ruby Glasses and Turrita and sketching some hypotetical clothes for the two fillies. As Rarity was drawing up the hem of a dress, she found her lower body slightly aching and in need to be empitied. Rarity gritted ehr teeth, as she finsiehd up the drawing, before putting down the green crayon.

"Excuse me, darlings, but I need to do something," Rarity said, getting up and gesturing at the two fillies, who looked with puppy dog eyes at Rarity, who was leaving.

"I will back at you very soon, my little ladies," Rarity siad with a wink, as she went towards the desk, where Nutriz was sitting while scribblind something down on a document. Rarity faked a cough, and the teacher lifted her head up, lookign at Rarity.

"Yes?"

"Nutri- I mean, Ma'am Nutriz, could I please, um..." Rarity blushed a little, then took al her courage in two hooves and said "I need to go out of the class for use the bathroom. Can I go there, please?"

The teacher made a clickling soudn with her mouth. "No, you can't. Wait until Potty Time and we'll talk about that."

"But..."

"No buts and no exceptions," Nutriz then smield and booped Rarity's nose "go back to play with your friends now!"

Rarity pouted and crossed her hooves. "No, I will not, please let me go."

The teacher shook her head, and, seeign there was no point, Rarity sighed and went back to her two little friends.

Hopefully she wasn't going to use her diaper. As she walked next to Turrita, Rarity saw that Turrita holding a jack-in-a-box. Shortly after, the jack-in-he-box opened, but, instead of the usual puppet, Pinkie Pie exited from it, shouting "HI!" and hugging Rarity tightly.

Rarity felt her bowels loosen in surprise. When she realized that...
