Chapter 3
It was about an hour after putting on the diapers for the first time, and the 5 furs were playing in the playroom. They had just finished up the tour of the camp building, having seen the playground, the dining hall, their sleeping quarters, the bathroom (which didn’t have a potty of course), and the few classrooms and playrooms for doing activities. Lunch was going to be served in about 20 minutes, so for now the kids were just playing to pass the time. Winter was sitting looking over them, because Tart was helping the kitchen staff with preparing lunch.
Misty was rolling a toy car back and forth across the floor, when behind her she heard: “Winter? Winter?! Winter!” she turned around to see Red squirming uncomfortably, waving his paws in the air to get Winter’s attention.
“What is it Red?” asked Winter walking over to the little fox.
“I really really REALLY need to go potty!” replied Red, pressing his paws against the front of his diaper.
“Do you need some help using your diaper for the first time?” asked Winter gently. Red nodded desperately, continuing to squirm uncomfortably. “How about you try this,” said Winter, grabbing a firm pillow that looked like a chocolate covered donut. “If you pull down your pants (but leave your diaper on) and sit on this it will feel a little bit closer to being on the potty. That might help you go more easily.”
Red nodded, continuing to squirm and hold his paws on his diaper. He pulled his pants down, revealing a white diaper with a fire pattern. He sat down on the donut pillow, and removed his paws from the diaper. “Now, just try and relax and let it happen,” said Winter encouragingly. Red nodded and took a deep breath, trying to relax his body. Suddenly, he let out a slight gasp that quickly turned into a sigh as he fully relaxed into the donut pillow. “Good job bud!” said Winter, rustling the fur on his head. “All done? Do you want a change or do you want to wait until later?”
“I think I want a change,” replied Red, looking down at his diaper that now seemed slightly swollen at the front. “That felt weird. But not in a bad way. Just in a weird way.” Winter and Red walked out of the room, leaving the other four there to play.

Lunch was very pleasant. The five young furs and their two counsellors all sat around a table and had PBJs, chicken nuggets, sliced carrots, strawberries, and lemonade. After the big meal, Misty leaned back in her seat.
“What’s happening now?” asked Tilly curiously.
“Well,” said Tart. “On a normal day we would do some sort of activity now. But since it’s the first day it might be best to just take some more time to get settled.”
The group went outside to the playground to just have some time to have fun and get to know each other a little better. Misty was playing on the seesaw with Tilly when suddenly she felt a familiar feeling in her belly.
“Winter? Tart?” she called out, hopping off the seesaw and running over to where they were sitting. “I need to go potty… but um… I need to…”
“Have you got to do a number 1 and a number 2?” asked Winter, gently teasing the little bat. Misty nodded, tears forming in her eyes.
“Hey, that’s okay. That's what your diapers are for.” said Tart, noticing Misty’s discomfort. “Do you want to go somewhere a little more private?”
Misty whipped her eyes and nodded and Tart led her inside and into the playroom. They went over to the donut pillow that Red had used before. Misty pulled down her shorts and sat on the donut pillow. Despite the diaper and the squishiness of the donut pillow, it did strangely feel quite a bit like being on the potty. The pressure in her tummy was building though, and she could tell what was going to happen soon, whether she liked it or not. She flapped her hand nervously, not sure if she was ready.
“Just relax,” said Tart gently. “It’s okay. In fact, that's the point.”
Misty closed her eyes and tried to relax, almost immediately feeling a warm, wet feeling spreading across the front of her diaper. It felt much more pleasant than she thought it would, but the pressure in her tummy was only continuing to build. Taking a deep breath in, she clenched her hands into fist and pushed. It took a few pushes, but she started to feel it coming out. With one last big push, a heavy weight fell into the diaper, causing it to sag down a little in the back.
“All done?” asked Tart, to which she nodded. “Good job, let’s go get you changed.” Misty followed Tart into one of the changing rooms, getting up on the changing table. She felt weird having her mess squish up against her body, but it wasn’t actually bad. Tart pulled off her shorts and untapped the diaper. He wiped her up thoroughly, making sure she was nice and clean, before putting on a new diaper and helping her off the changing table.
“Before you head back out to play, there’s one more thing we need to do.” said Tart, pulling a clipboard out from the cabinet. He shuffled through the papers and wrote a few things down before holding out the clipboard to Misty. “Here, you can pick out two stickers and stick them onto this chart here.” Misty selected two matching sparkly rainbow stars and stuck them into the first spot on the chart.
“What are the stickers for?” she asked, looking over the paper to try and figure out what it was for.
“It’s a diaper training chart.” he replied, tucking the clipboard back into the cabinet. “Just like how you had a potty training chart, this chart will track your progress on using diapers. When you fill it up to a certain amount, you’ll get a prize.”
The two walked back outside and were met almost immediately by Tilly, with Winter just behind her.
“How was it?” asked Tilly excitedly. “Was it hard to do? What did it feel like?”
“Now now Tilly,” said Winter, placing a paw on the young horse’s head. “I’m sure Misty will tell you all about it when she’s ready to. For now, I need to take Bubbles in for a change. They’ve also done their first number 2.”
