A Tough Lesson

Several hours had passed since Cozy Glow had tried to take over Equestria and become Empress of Friendship. She had been captured and placed in a random guest room for holding. Various ponies who thought she was their friend were angry, and some were sad to find out how evil she’d turned out to be. How could she have done all of this and for what? Because she wanted friends?

In Cozy Glow’s head she thought she had done the right thing, all she wanted was to make ponies be her friends and complement her. Why did the ponies see this as a bad thing? Friendship meant power, the more friends one had the more powerful they became. And the filly had thought that if she played her cards right, she’d be make everypony be her friend. So where had it all gone wrong?

“I don't get it. I just wanted some friends, is that so wrong? Making friends is easier when you have power, power means respect.” She thought as she looked at Twilight from behind, as the filly was pushed into the guest room. For her own safety, she’d been told. What, did they think anypony would want to hurt a defenseless filly like her?

“I’d hoped they’d send me directly to Tartarus, I really want to pay a visit to my ‘pen pal’ and tell him how wrong he was,” Cozy thought to herself. Everything had been going great until those nosy creatures and the annoying Sandbar got in the way. But on the bright side she had managed to at least prevent anypony from figuring out her true goal. The magic drain was only the first step, once she’d taken because she saw no other way to get attention. “It's weird since I gave them a few hints. Can’t they figure anything out? They think a filly like me would reach out to Tirek just ‘cause I wanted friends?” She paced around the room and waited. She thought of escaping through the window but that wasn’t a good option. Celestia and Luna had put guards all around to prevent her from escaping. She was in fact a prisoner already.

“I guess I have no choice but to wait and see what they do to little ol me.” She said to herself and walked over to the bed and lay down while she waited for the Princess of Friendship. She fully expected Twilight Sparkle to walk in and send her straight to Tartarus, the only thing suitable for a filly like her especially after what she recently did. And when she did, she’d be sure to give Tirek a piece of her mind for ratting her out. Some friend he turned out to be.

Although she sat silently in the room the filly didn't exactly like it, she was surprisingly bored out of her mind. She walked to the wall and tried to see if she could hear anypony from the other side but all she could hear were muffled sounds.

Twilight stood in between Princess Celestia and Princess Luna her thoughts remained on Cozy Glow. The one pony she thought she could trust, the pony no one expected to just betray them. How or why did that filly think it was right? Yet was Tartarus really the best place for Cozy? She had been pen pals with Tirek, after all. And never in Equestria’s history had a child been sent to Tartarus. Then again, a child had never done what Cozy had done.

But Twilight couldn’t convince herself that Tartarus was a suitable punishment. “Princess Celestia, Princess Luna,” She gulped. “I know what Cozy Glow did was bad, and what she did deserves serious punishment. But... I think it's going a little too far sending her to Tartarus. Give time to figure out a new punishment for her. Maybe I could even find her parents to get their side on this. She has to have parents or caretakers somewhere.” The young alicorn spoke up, awaiting the princess’ response.

Princess Celestia wasn’t exactly happy about this. Tartarus was a harsh punishment reserved only for the worst offenders, and it was hard for her to stomach the idea of sending a minor there. But Twilight had managed to redeem those that seemed lost before: Sunset Shimmer, Starlight Glimmer, and even Discord were all testaments to her abilities (even if Discord was more Fluttershy’s doing than anypony else’s). “Twilight, I would gladly let you pick the punishment. But it needs to be one that changes Cozy into a better pony, one that understands friendship,” She declared. “If you need to you can go look for her parents, but I highly suspect her file might not have any. Still, as long as Cozy can do nomore damage, take as much time as you need to think of an alternative to Tartarus. I’ll decide if it’s suitable for the crime.” Celestia replied and decided it was time to leave.

Princess Luna simply said to Twilight “I’ll just leave the guards here until you figure something out. Choose wisely. If Cozy’s punishment is too lenient, ponies will think she’s getting off the hook and peace may not be restored.” Then Luna followed her sister back to their castle, leaving Twilight to stand there and think about this mess.

A little later, Twilight arrived back at her castle. Spike was already inside, waiting for her. “Hello, Spike,” She greeted the dragon. “I suspect you enjoyed today's Power Ponies issue?

Spike only nodded, he knew Twilight doesn't really care much for Power Ponies. Plus he could see Twilight was quite stressed out simply by the look in her eyes. “What's wrong, Twilight?” He asked as he got her a seat.

Twilight sighed as she sank into the chair in the castle library. “It's this mess with Cozy Glow, it makes me sad for her. I know it’s probably wrong to feel that way but I can’t help it. That her of all ponies would betray us like she did, using us to get what she wanted. We were going to send her to Tartarus. Spike! Tartarus!” She exclaimed in horror! “But... I thought it was a little extreme for such a young filly, even considering what she did. I need to figure out a better punishment before tomorrow. If I don't," She gulped and finished by saying “She'll have to go to Tartarus! Oh, I am such a failure! Not only did I not notice the warning signs with Cozy, but I also couldn’t give her a punishment that would help her learn about friendship!”

“You’re not a failure, Twilight! You just need to fix this,” Spike encouraged. “You’ve been able to redeem ponies no one else thought redeemable. Even Tempest, and she was working for the Storm King. I know you’ll find a solution that works for everypony. If you ask me, I think Cozy needs a little bit of discipline in her life to straighten her out. Maybe if you let her know what fate awaits her if she doesn’t change her ways, you can scare her into going straight.” He suggested and walked back upstairs to his room, deciding to let Twilight work this out by herself (Starlight was still recovering from regaining her magic after being imprisoned inside that bubble).

Twilight reluctantly walked to her own bedroom a short time later and looked though some of Cozy Glow’s files. She had to find her parents, maybe get their point of view on this. Surely they would know why Cozy had gone so wrong.

Yet as she looked, the princess couldn’t find anything on her parents. In fact it seemed as if Cozy Glow had written everything herself when she signed up to go to the school. Even the signatures looked way too similar to her class writings. “But in order come to my school you need a parent to help sign these! Please tell me she didn’t sign it on her own!” She mentally pleaded and just re-read everything over and over again. Yet there it all was, plain as day.

“Huh this is most definitely her hoof writing, it seems she either isn’t in contact with her parents or doesn’t have them,” Twilight thought. “And since I have no idea who her parents even are, I guess as School Headmare, I have to give her a suitable punishment, one that she deserves. But what?” She closed the files and walked around the room for a while, thinking about a decent punishment. She first thought of maybe putting Cozy in a cage without having to send her to Tartarus. Let her be locked up as an example, and she would earn her freedom when she was ready to be reformed. But even that felt like too much to Twilight, if she was going to put Cozy in a cage then why not just send her to Tartarus? The punishment needed to be more suitable than that, something that could ensure Cozy learned her lesson.

Then, out of the blue, an unconventional idea came to Twilight. “Hm. She's going to hate this but I think this might help Cozy Glow learn to accept friendship in the long run. If she wants to act like a foal then that's exactly how she’ll be treated. And Spike also had a good idea, she will probably need a fair deal of discipline after what she’s done. I just hope she won’t be too much of a hoofful.” The princess said aloud and galloped outside, giggling all the way to the foal store. She smiled, confident of her solution. “I’m sure Celestia and Luna will approve of this rather unconventional method. Foal years are the best time to get them educated.” She thought.

A day had passed since Cozy Glow commited the crime, and Twilight and her friends (who had all been filled in on the plan) were preparing a special room in Twilight’s castle for Cozy Glow, a nursery of sorts. “If that filly tries to escape you better have a plan, Twilight,” Rainbow Dash commented in worry. “And what if she tries removing her… you know what?”

“Don’t worry, Rainbow Dash, I’ve got both covered,” Twilight reassured her friend. “Though I’d like to leave the spanking to you, Rainbow Dash. You’re a lot tougher when it comes to that type of punishment.”

“For a pony like Cozy, she kind of deserves it. Nothing personal.” Rainbow admitted.’

Twilight just finished putting the troys in the crib and a few stacks of diapers in the closet. “Now then, girls, I need one of you to bring the foal here to begin the punishment. Pinkie, would you mind doing that? You have the most experience with foals out of any of us.” Twilight asked her party planning friend.

“Okie dokie loki, one naughty foal coming up,” Pinkie replied and hopped out of the room, surprisingly eager to bring Cozy Glow to her new room. “This is going to be super duper fun. Just when the Cake Twins are starting to graduate from diapers, we get a brand new foal to take care of. And if she acts naughty… well, Rainbow Dash will give her something to think about for sure.”

Pinkie was fast at bringing Cozy Glow in. She’d been told they were getting her punishment ready and the filly thought for sure that meant they were going to send her to Tartarus. But she had no idea how wrong she was going to be. Something even worse awaited her.

Cozy saw that it was a pink colored room. Pink down to the walls and carpeted floor. Foal toys were stacked all around, some unused pacifiers lay scattered on the floor and worst of all she saw different colored diapers in the closet. “I uh, I don’t understand. What is all this?” She asked, really confused. “I don’t wet the bed if that’s what you’re wondering, and I’m pretty sure they have bathrooms in Tartarus.”

“It's your punishment, baby,” Twilight cooed.” You sure love to act like a foal, a foal who still needs diapers I might add.

“But… I… don’t understand. Why would you do that? I thought I was going to Tartarus.” Cozy protested.

“You were, but Twilight thought this would be a perfect punishment for a missbehaved foal like yourself,” Rainbow instructed. “You don’t know how lucky you are to avoid that. But before we get into the nitty gritty of being a foal, come to my lap and bend over. You will receive a few swats to your behind!”

Cozy Glow’s jaw dropped upon hearing this. She thought she was going to meet her pen pal Tirek in Tartarus. But now they wanted to put her back into diapers and spank her like she was a foal that had done something dangerous. Naturally, she protested and stuck out her tongue. “I refuse to listen to your words! If you need me, I’m leaving and going somewhere where a filly like me won’t be a bother to anyone! I hear the Everfree Forest is lovely this time of year.” She began to walk towards the back door, but to her surprise Pinkie and Rarity stopped her by blocking the way! Then she went towards the right and to the window, hoping to get out that way. But Twilight used her magic to close and lock it.

Cozy Glow looked around the room for any sort of way that she could escape! She saw one thing that she could hopefully fit into. Next to the wall she saw a vent, she flapped her wings as fast as she could and flew towards it!

But she didn’t reach it in time, Rainbow Dash flew over and caught her before she could even get a chance to escape. “Let me go you big bully!” Cozy complained and squirmed in the cyan mares hooves, trying hard to escape from her capture but to no anvil.

“You know, I’m getting real tired of this, enough is enough! It's time for you to get what you deserve!” Rainbow Dash declared and put Cozy Glow on her stomach as she gave her some small swats on her her rump. The filly squirmed and tried to escape as Rainbow Dash spanked her, but she couldn't get away from this. For the first time In her life somepony actually punished her. She’d always gotten away with things before but this was too much.

Cozy Glow gasped as Dash laid her hooves on top of her flank “Let go of your empress this instance! I demand it!” She cried out, only to be ignored.

“My mother used to give me spankings when I acted badly, which wasn’t often but it still hurt. What makes you think you should be treated any differently?” She asked and continued her spanking attack.

“Okay, OKAY! I’m sorry! Please, just stop, ow, spanking me!” Cozy yelled as a few tears flowed off her cheeks. She wasn’t expecting it to be as painful as it was. She rubbed her reddened bottom when Dash released her.

“Okay, Dash, I think that's enough for now. But if she does misbehave like that again you can punish her,” Twilight advised. “But for now, let's get the foal into her diapers so her cheeks can cool down. Now come on, Cozy Glow, we wouldn’t want you to make a mess on my floor now would we?” She asked and motioned for the foal to come forward.

Cozy sighed, she was in no position to fight back. “Whatever, just because she's putting me back in diapers doesn't mean I have to listen. She wants me to wear those stupid things? Well I’ll make sure to give her a very hard time with her new foal.” She thought and reluctantly laid down on the changing mat.

Twilight smiled and cooed at the foal “Okay then, shall we get started?” She asked and gathered the supplies.

Cozy knew this was going to be real tough. But what's the worst that could happen? Being a foal couldn’t be that hard could it? She’d just need to do it until they got tired of her attitude and sent her to Tartarus.

Author's Note

This Is officially the first padded story with Cozy Glow, I felt like she deserved this after everything she did, I'm not completely sure how long this story will be.

First Day Padded

Twilight used her magic and levitated over a diaper the perfect size for a grumpy little filly, some powder to help Cozy Glow’s bottom after being spanked. She thought about bringing some mittens so Cozy wouldn’t be tempted to remove her padding, but she thought it would be better to let Cozy see what happens if she ever tried taking it off. “She's going to be in for quite the surprise! Foals shouldn’t play with their diapers.” She thought and levitated Cozy up a little bit to slide the purple colored diaper underneath the filly’s rump.

Cozy Glow started squirming as the alicorn placed the diaper underneath her. Her breathing started to increase, she (needless to say) didn’t like the idea of having to put diapers back on. Especially since she’d been potty trained for at least ten years. She could remember it had been a nightmare for her parents to potty train her, and now she was being put back into the very thing she thought she’d be done wearing.

Twilight got really annoyed with this squirming. “Cozy Glow, stop that this instant unless you want another spanking from Dash!” She protested as Dash started to walk closer to Cozy.

Cozy found herself at a complete loss for words. She didn’t want another spanking, that last one had been more painful than she thought and her rump was still sore. She finally managed to find the courage to squeak out. “I... uh, no I don’t. I… I’ll be a good girl, I swear.” And so she sat completely still for Twilight and let the headmare finish the diapering job.

Twilight smiled and put the powder over Cozy Glow’s rump, then taped the diaper up snuggly around her waist. She helped Cozy up and gave her a small pat on the rump. “Aww, you look so adorable in your new diapers Cozy. Now let's get your pacifier in, shall we? If you’re going to wear diapers, you might as well look the part.” Cozy simply pouted and folded her hooves. How had she ended up in this situation?

Pinkie Pie, meanwhile, hopped over and just for the sake of it checked to see if Cozy Glow had used her diaper. Everything seemed okay. “Huh, I could’ve sworn I heard a hissing noise coming from this. Oh well, must be my imagination. Even the twins don’t need diapers anymore. Don’t worry, the foal’s still clean, Twilight,” She said at all once, saluting her friend. “But if she needs a change and you need some pointers, just ask me. I have plenty of experience foalsitting Pound and Pumpkin Cake.”

“What do you think you’re doing, you idiot? I know how to use the potty!” Cozy Glow snapped. “I don't need these stupid things!” And she slapped Pinkie’s hooves away.

Then Cozy started to notice there were a lot of toys in this place, many of them designated for her. She felt like it was a little too much, not even a foal would be able to play with all those toys. Her thoughts were interrupted as a small, purple colored pacifier was shoved into her mouth, making her lose her train of thought.

“Wow, somepony’s grumpy,” Pinkie commented. “Nopony likes a pouty baby.”

“Pinkie’s right,” Twilight spoke up. “And since you’re going to be a baby, Cozy Glow, you might as well act the part. But first, let's get the rules taken care of. Now sit down and hear me out, Cozy, unless you want to sit on my lap while I read the rules to you?” She asked in an almost motherly tone.

Cozy Glow looked at her new guardian with disgust. “I absolutely refuse to sit on your lap!” She hissed and sat down on the floor. The new rules couldn’t be that bad, right?

Twilight smiled at the cooperation. “She’ll come around to this stuff eventually, I hope,” Twilight though, hoping Cozy Glow would be a good girl one day (now that's what she was looking forward to the most). She levitated her short list of rules for Cozy Glow to her as she thought. “She's going to hate us for this, but it has to be done!”

“Okay, Cozy. The first rule is: You have to go to bed when we tell you to. That means no hissy fits, no temper tantrums, no buts or what ifs about it, and no exceptions. The second rule is: You will from now on drink out of baby bottles and eat only what is served to you. If anypony catches you trying to eat or drink from the grown up plates and cup, you will be put in the timeout corner,
The last and most important rule: You have to use your diapers, at least until you can prove to us that you’re learning. But if you’re good you might be able to use the potty again someday,” She instructed as she put it away and walked over to Cozy Glow as she smiled. “Now please try to listen and be a good girl, okay?”

Cozy Glow got up and out of anger slapped Twilight, there was no way anypony would make her use only her diaper, that was insane! “There's no way I’m going to use my diaper! You might have me in diapers but that doesn’t mean I have to use it! She screamed, only to be levitated by Twilight’s magic.

“Cozy Glow bad girl!” Twilight scolded. “You do NOT hit ponies! She walked over to the timeout corner and placed her young charge on a stool, plopping her down as her diaper crinkled.She was sure to put a magical setrap over her so she couldn’t escape. “Now sit here for ten minutes and think about what you’ve done, baby.” She instructed and then decided to check up on Starlight Glimmer to brief her on the punishment.

Not long after Twilight left, Cozy Glow tried to escape. As she did so her diaper crinkled and she blushed deeply. “The moment that dumb alicorn lets me go, I’m going to rip this stupid diaper off and throw it in her face!” She declared, before she noticed the pacifier Twilight had given her was on the floor. Although she didn’t really want to do it, the filly wondered if a pacifier would soothe her. It was better than sitting here with nothing to do, that stupid magic strap held her more or less in place. Reluctantly she reached down, put it in her mouth and suckled on it for a few minutes. “Huh, I guess this isn’t too bad…” She unknowingly said aloud as a flash of light not unlike that from a camera hit her! She spun around and saw that Pinkie Pie had taken a picture.

“Aw, little Cozy Glow is enjoying her paci. I’ll be sure to put this up on the wall to show Twilight,” She cooed and put the camera away. “Now be a good girl, Coz. There’s only five minutes left and then you’re free to move.”

Twilight returned shortly with Starlight, having filled the unicorn in on Cozy’s punishment and what it entitled. “So, Starlight would you mind watching over Cozy Glow tomorrow?” She asked. “I have to visit the princesses and tell them everything that's going on, as well the punishment we’ll be giving Cozy. It’s certainly better than sending her to Tartarus for life.” She said with a bright smile.

“Okay I guess,” Starlight replied. At least as a diapered foal Cozy didn’t seem like she would be able to cause anymore harm. “Maybe could I dress her up and take her out to the park?” She suggested. “I think she’d like her new situation more if she was around other foals,” She waved at Cozy Glow. “I must admit, those diapers do look good on her”

“I know, I had no idea foal stores were in on my popularity too,” Twilight giggled. “And dressing up Cozy could work. It might help her understand friendship a lot more, if she’s around foals. They could also probably serve as a role model for her. Just keep an eye on her, because something tells me our new little one is going to be quite the explorer.”.

Cozy, meanwhile, saw that the magic strap had finally released her. But as it did she tried to remove her diaper with her hooves. Instead of ripping it off however, the diaper became bigger and poofier, making it harder for her to walk. “HEY! What gives?!” She demanded in a confused tone as her diaper inflated.

“I knew you'd try to remove it, which is why I took the liberty of putting a spell on the diapers,” Twilight explained. “If you try to remove it, it gets poofy and harder for you to walk. Only the grown ups can remove it, not you silly filly. And don’t even try removing it with scissors, it won’t work. I put everything I had into that spell, and from what I read parents used to place on their little ones diapers all the time, until foals started inflating their diapers to the size of balloons,” Then she smiled. “Let’s put you down for a nap for now, shall we? You’re being quite the fussy foal today, and I think that’s because you didn’t take your nap. All foals get fussy if they don’t take their naps.” She picked up Cozy Glow with her magic and carried her over to the crib slowly, making sure her foal didn’t fall. Soon, she put her safely in the crib and covered her up with a blanket.

“Oh, I almost forgot!” Twilight realized and rushed out of the room. She quickly came back with a warm bottle of milk and put it in Cozy Glow’s hooves so she could drink it. “Drink up little one, it’ll help you sleep.”

Cozy Glow sighed, there was no other choice here. She couldn’t get the diaper off, so she had to obey them, for now at least. It didn’t mean she’d completely listen to them, she’d be sure to give them the most uncooperative foal imaginable before long. But for now she was kind of thirsty, so she started drinking her warm milk. Once she’d finished, Twilight picked her up and burped her, then put her back in the crib. “Goodnight sweetheart.” She called and she kissed Cozy on the head, then turned off the lights and left the room.

“This is going to be a long and embarrassing stay,” Cozy said to herself as her tummy started growling ominously. “Oh please just be hungry, please don't let it be my other business…” She pleaded and tried harder to sleep, through the extra padding on her rump made it difficult.

Attempted Escape!

Cozy Glow tossed and tuned in her brand new bed inside the castle. Being put to bed was humiliating enough. But a crib? That was just too much! The filly refused to be any part of this! She wasn’t going to let them humiliate her, they would never earn that privilege.

The filly’s thoughts soon turned to her diaper, namely what Twilight had allegedly cast on it. “Twilight might have a spell on these cursed things, but that doesn’t mean they’re invincible, I’ll find a way to remove these stupid diapers before I’m forced to use them! I’m not stupid, helpless baby!” She thought as she turned around. Her eyes fell upon a huge teddy bear in the room with a big smiley face. She frowned.

Clearly, somepony had put that there. She hated it, it looked like it was watching her. And that made it hard to sleep. “How in the world am I supposed to sleep in this thing?!” She thought. She tried her best to find a spot that could work out for her. Out of her own curiously she poked her diaper, it made a small crinkling noise as she did so.

“Wait a second,” Cozy realized. “Those fools think I’m already asleep. I can take advantage of that. I’ll escape!” Then she looked down at her diaper. “Although, I’ll have to find some way to remove this stupid diaper. Maybe I could run to the Everfree Forest! They’d never be able to find me in there.” She said quietly and wiggled out of her crib as best she could. She fell down hard on her rump, but the softness of her diaper prevented any sort of serious damage.

Cozy still rubbed her bottom. The fall had been soft but she was still hurting from that spanking earlier. Not even her parents had ever spanked her that hard before. “Curse that Rainbow Trash!” She growled. “I swear when I get complete and ultimate power, I’ll force her to be spanked every single day for the rest of her miserable life! See how she likes it, mwahahaha!”

The filly stopped her cackling and started walking to the door. Or at least, she tried to. It was really more of an embarrassing waddle due to the thick diaper she was strapped in. Even so she was able to reach the door. She opened it very slowly and peered out. She saw Spike sleeping next to the door with one of his comic books on the floor in front of her.

Cozy, being the curious filly that she was, bent down and picked the comic up. She took one look at the cover and gagged. “Power Ponies?! Yuck, only losers read this garbage!” She declared and tore it into tiny pieces, not even caring about Spike’s feelings. Just looking at the comic made her sick. “If I had won against Twilight and her friends I would've totally banned comics, they’re useless!”

Spike’s eyes fluttered open a tiny bit. He could’ve sworn he heard something, but he didn’t notice the padded filly just out of sight behind the door he was guarding. His eyes began to droop and he turned to his side to get more comfortable. As he fell back asleep, he muttered. “Twilight told me to keep an eye on Cozy Glow. But I must be hearing things, she's probably still sleeping.”

Cozy Glow watched as Spike fell asleep, then carefully pushed the door open the rest of the way and waddled out. She was surprised at how how soft her diaper was. It’s too bad it was stuck on her so tight and added so much weight to her, otherwise she could see being somewhat useful.

For now though, there was the dilemma of how she was going to get out without being noticed. “Hm… I could probably climb out the window If I wanted to and not get hurt, but I’ll try that later. They’ll probably be expecting me to do that,” She thought. “I can just escape though the front door, nopony would expect me to do something so obvious! Although, I haven’t planned out what I’ll do once I leave. I just hope nopony sees me like this.” She thought and galloped downstairs.

Cozy looked at her diaper as she slowly descended the steps (there were sure were a lot of them in the castle for some reason). “I really don't want to use this diaper, there has to be a way to take it off,” She thought out loud. “Perhaps I can find that zebra everypony talks up and force her to cook up a potion to remove it? I hear she’s friends with those nosy Cutie Mark whatever they call themselves, bet I can use that to my advantage.” She gleefully started rubbing her hooves together.

A short time later, Cozy finally got downstairs. When she did she saw Starlight Glimmer just around the corner, sitting in a comfy chair and reading a newspaper. It looked almost like gossip of some kind.

Carefully, Cozy snuck behind the wall of the room. She looked towards Starlight, who was indeed a few feet away. The filly had to make sure that pesky unicorn wouldn't even notice her leave. She had no way to trap the unicorn this time.

Starlight was unaware of Cozy’s presence. She just yawned as she got up and stretched. “Well, I guess that's enough reading for today. I need to get some fresh water, then I guess I'll check on the diaper baby before bed.” She declared, putting her newspaper down onto the table and going to the kitchen (which was about two rooms away from the main hallway).

Cozy Glow smiled happily. “This is too easy! Since that stupid Princess doesn't have any guards, I can easily escape without a problem. Sorry Princess Moron, but I win!” She announced and rushed towards the door at the end of the hallway! But she slipped and fell due to her diaper’s weight! She couldn’t stop her headlong slide, and hit her head against the door. “Ouch! That could've gone a lot better….” She grumbled. “Stupid diaper!”

Upon getting back up, Cozy could hear what sounded like hoof steps coming from both the stairs and the kitchen. She had to hurry and escape, otherwise she would be caught! And escaping from this castle next time would surely be harder as a result.

Cozy rubbed her head, quickly got back up on her hooves, and opened the door. But just as she took a step outside, she was caught in some type of huge net and dangled off the ground! It was then that she noticed a wire below the doorway. She had tripped it without even noticing. “Those sneaky little..” She grumbled, struggling to break free of the net.

As she did she began to notice ponies walking around outside. They would totally see her in her diapers if she did escape, and that struck the filly with a sense of dread! “What will I do if they see me?!” She thought. “I don’t them to make fun of me!”

Spike, Starlight and Twilight came upon Cozy Glow a short time later, and both mares gave a high hoof to each other. They had set the net up just in case something like this happened.

But that also meant that Cozy had tried to escape even after she’d been warned not to. So that meant that now somepony had to give Cozy another spanking. It was obvious that giving her a time out alone wouldn’t suffice.

Twilight used her magic to release Cozy from the net and set the trap back up. She then brought Cozy back into the castle. As she did she was anything but pleased. She was quite furious with the little foal before her and looked her straight in her little eyes, smoke billowing from her nostrils.

“Bad girl, Cozy Glow!” Twilight scolded. “Babies don't get to go outside without a parent to watch them! You could’ve gotten hurt or stuck somewhere! I want an apology, and I want it NOW!” She roared only to have Cozy stick her tongue out at her.

“That does it! You leave me no choice, Cozy!” Twilight scolded and raised her hoof, moving it towards Cozy’s bottom. But before she could bring it down she hesitated. After almost a minute she simply sighed. Something inside her was preventing her from doing it. She didn't really like the idea of spanking Cozy, even considering what the filly had just tried to do. “Starlight, could you spank her?” Twilight suggested as she turned towards the unicorn. “I know I should do it, but I really don't want to. I just don't like the idea of it, even though she needs to be punished, especially with the stunt she just pulled.” Then she pulled out a scroll.

Cozy Glow took a look at the scroll and gasped at what was written on it! “‘Cozy Glow’s Good Day Scroll’?” She wondered what that was for.

Twilight put the scroll on a nearby table and then placed a huge, red X on it! “I was going to give you a check, but you screwed up Cozy,” She then explained. “I was thinking that if you could behave yourself for a week we could see about restoring your potty privileges. But at this rate if you’re going to keep being a naughty foal, you’ll never be able to use the potty like a big girl! You’ll probably be stuck in diapers forever!” She levitated the paper into her saddlebag. “Starlight, you take it from here.” She instructed, and left the room.

Starlight smiled at Cozy Glow. “Okay, Cozy Glow come on sit on my lap,” She spoke as calmly as she good. “It's time for your spanking. I got spanked a few times as a foal myself. It doesn't actually hurt that bad, though I think that’s because my dad was always gentle with me and was never big on the whole spanking thing to begin with,” She pulled the filly close with her magic. “Now, unlike Rainbow Dash I won't go easy on you. You’ll get three swats from me, but I’ll be using a belt, not my hoof.” She proceeded to levitate a small belt over. She had gotten it from Rarity but had never really seen a use for it, until now.

“Three?! No, Starlight she deserves ten at least!” Spike explained. “I found out that, while I was asleep that Cozy brat ripped my Power Ponies comic into tiny pieces! Sure, Twilight restored It with her magic, but Cozy still ripped it up for no good reason. She deserves more then three!” Spike said as he stormed out of the room, still furious about his comic.

Starlight blinked a few times and said. “I guess Spike’s right, Cozy. You shouldn’t touch what doesn’t belong to you. How would you feel If Spike ripped up one of the stuffed teddy bears in your room? Don't try lying to me, I know you love Mr. Snuffles, I saw you holding him in your sleep before.” She brought the belt closer.

“I don't like that stupid bear! But I bet you enjoyed being trapped in that magic barrier I had put in back in the school! Take me back there and I can happily put you and everypony else back in!” Cozy taunted with an evil grin.

Starlight felt torn up to see the filly act in such a way. “It’s just like when that I ran that village in the middle of nowhere.” She thought to herself. But if she could change, then so could Cozy if given the proper guidance. So a spanking was necessary.

Starlight knew that with that diaper on Cozy would be protected from the impact of the spanks, so she used her magic to slide it down a bit and then started swatting her with the belt. As she did she could hear little sniffles coming from Cozy Glow. Once she finished her spanking, she put the diaper back on the filly and said. “There, there. That wasn't so bad now was it, Little Miss Fussy Pants?”

Cozy just stuck her tongue out as Starlight brought her into a loving embrace, hating the hug. “What does she think I am a one year old?” She thought as she was released from the hug.

Starlight. meanwhile, gladly checked Cozy to see if she had wet her diaper at all or otherwise used it. Remarkably, she was dry. “Wow, I’m impressed, Cozy Glow. You still haven’t gone poopy or wet yourself yet. Not many foals could keep their diapers clean this long, even I had trouble keeping them dry all night as a foal.”

“That's because I’m never going to use them! I’ll hold it in for the rest of my life If I have to!” Cozy mentally vowed. She wasn't completely suer how long she could really hold it, but she was NOT going to use the diaper for any means. No matter what, she wasn’t going to break!

finally have a chapter out for this story, sorry for taking forever.

Cozy's Accident

While Cozy was being punished, Twilight decided to get some breakfast ready. She figured that with Starlight taking over punishment, she could at least try doing other things for the poor dear since it had been her idea to treat her as a foal. She could do things like give her bottles, burp her, change her diapers when needed, and maybe even play with some toys alongside her. That last one in particular felt kind of odd to her.

“Cozy Glow’s not going to enjoy this, but how else are we going to reform her? At least this way she won't have to go to Tartarus, the poor foal would've gotten scared for sure. It just isn’t right.” Twilight said to herself as she levitated a bowl and some pancake mix over and began making some for her friends. She thought about serving them to Cozy, but decided against it. If she served those it wouldn’t be much of a punishment. “Perhaps some fresh baby food will work, until she acts more mature anyway. Besides, I don’t what she normally eats. This way I can ensure she gets her nutrition.” She thought to herself.

Spike walked into the kitchen while Twilight was in the midst of thinking. He had just put his restored comic on a shelf, now hopefully away from Cozy Glows’ evil little hooves. “I actually wish I could’ve spanked her. I was supposed to be watching her, and it was my comic she ripped up.” He remarked.

Then as he took a seat at the table, he also noticed an old looking high chair Twilight had brought out. In fact, it looked like one of his old ones and he cringed. “Twilight….. Did you really keep this old thing for all this time?” Spike inquired. Twilight confirmed with a nod. “W-why did you keep it? I know I used it a lot as a baby. I mean, you can even see some of the burn marks I left on it. Is this safe for Cozy to use? What if breaks?” Spike asked while blushing deep red.

Twilight put the pancake mix down and cooed. “Why of course I brought it. I mean, I did bring some of your old stuff to my castle when I visited Canterlot a long time ago. I’m actually going to visit my parents later today to pick up a special surprise for little Cozy Glow.”

“Yeah but did you rea-” Spike began, but was unable to finish his sentence as he saw Starlight Glimmer walk into the kitchen, holding a squirming Cozy with her magic.

Spike blew some smoke out of his nose as he saw Cozy Glow. After what she had done to his comic last night, he now didn’t even want to see the naughty filly. She was a brat, plain and simple. “Let's talk about this later, Twi.” Was all he said and sat down far away from Cozy Glow.

Starlight stretched her hooves as she brought in Cozy Glow. “Well, surprisingly shes still dry and hasn’t made a mess in her diapers yet. But she can’t hold it in forever, she’ll go eventually. Worse comes to worse, some laxatives should do the trick,” She declared as she used her magic, levitated Cozy Glow into the highchair, and strapped her in nice and snug. “There we go, Cozy. See what happens when you cooperate?”

Cozy stuck out her tongue. “Not like I had much choice.” She rubbed her bottom with a hoof, still feeling the impacts from Starlight spanking her with the belt. Even Rainbow Dash’s hooves hadn’t hurt as much.

Twilight smiled as she finished making the pancakes and put two each on plates for herself, Spike, and Starlight. But she only gave Cozy Glow one. Since Cozy was playing the role of a baby, she wouldn’t be able to eat a lot like the rest of them. Besides, it was a punishment. Every foalcare book said that parents had to set clear boundaries with their children and enforce them.

Twilight levitated each plate over to Starlight and Spike, and proceed to put some syrup on top of the pancakes. She then got a fork to feed Cozy Glow.

However, in the time it had taken to obtain a proper fork, it seemed Cozy had already took the liberty of trying to feed herself. As a result her hooves, stomach and parts of her diaper were all sticky and covered with syrup.

Naturally, Twilight was most upset. “COZY GLOW!!” She bellowed at the top of her lungs. “You know the rules! Only big ponies are allowed to feed you, you are just a foal after all. Now look what you’ve done, you’re a mess. And you’re going to need a new diaper, I can’t have you in a sticky, syrup covered one.” She groaned, before she grabbed a few napkins and got them wet, then she went to wipe Cozy Glow clean. Of course that was easier said than done, Cozy kept wiggling about in the chair as Twilight cleaned her.

At least Cozy was rewarded for her efforts with a clean and a pristine diaper, much as she hated the undergarments for how thick and poofy they were. They made it impossible to ignore her current status.

Once Twilight had finished cleaning Cozy, she decided to get the foal a bottle (with tiny hearts printed on it) of milk. “There we go, I got a special drink for our precious little foal. You probably need something to wash those pancakes down.” Twilight cooed as she brought the drink over. She picked Cozy Glow up out of the chair and put the bottle’s nipple into’ Cozy’s mouth.

Cozy Glow didn’t really want to drink the milk. it wasn’t bad enough that she’d already made a mess of her face, now she really had to go potty. Drinking the sweet liquid would only make her have to go even more. But unfortunately she couldn’t do anything to stop it from being offered. So she ended up drinking it slowly. Once it was down her stomach, she was surprised to have Twilight pick her up and pat her back. What was even worse was that she actually burped as a result.

When she was set back down it was all she could do to keep from tearing up as she did the potty dance, trying her hardest not to let anything spill into her diaper. She knew she wasn’t going to be allowed to use the bathroom. “That stupid potty chart! I should rip it up the first chance I get, just like I did to Spike’s stupid comic! That’ll get it through Twilight’s head that I’m not some stupid baby!” She thought to herself.

“Oh, I see somepony’s in a good mood. I’m so glad I could make you smile!” Twilight said as Cozy continued to do her little dance. She promptly picked Cozy Glow up. “Now, I know it’s probably hard to use your diaper with everypony watching. So why don’t I give you something to do to take your mind off that, and then you’ll just do it naturally when you stop focusing on holding it in?” She offered.

Cozy Glow was then placed into a playpen near the kitchen, along with other toys, puzzles, and plushies. She desperately wanted to take her mind off of using the bathroom, still determined not to go in her diaper no matter how tempting it seemed and how easy it would be to do so.

So the diapered filly picked up some blocks and just spelled out various words as Spike, Twilight, and Starlight watched her play for a while.

After almost half an hour of playtime, Cozy appeared to be content and under control. So Twilight asked Starlight. “Starlight, I think I should get going to Canterlot. I gotta explain the situation to Celestia and Luna like I promised. Plus, I wanna visit my parents and pick up a few things for Cozy. Do you think you can handle Cozy while I’m gone? Or should I prepare a schedule for you?” Twilight asked as she leaned over the playpen and checked Cozy’s diaper, which was of course still dry. “Hm. Could’ve sworn I heard a hissy sound, must be my imagination. I’m sure our little foal would tell us when she went. Can’t imagine she’d want to get an ouchie diapee rash.” She playfully teased while patting the foal’s head.

Starlight looked at Twilight with confusion. “A schedule? Why would I need a schedule? I’ve foalsat the Cake Twins already plenty of times, even if they were already starting potty training by the time I met them. I know how to take care of this big of a foal. It should be easy, there's not much she could need. And unlike a normal foal, she can tell me if she needs something.”

“Okay, but don't forget that this big ‘Foal’ tried taking over the world, and nearly succeeded too.Just try to be careful. And if you decide to take her outside at least be sure to keep a good eye on her, I wouldn't want her escaping from Ponyville. There’s no telling what she might do if she did.” Twilight replied and decided to just leave, biding farewell to everypony and even giving Cozy Glow a small kiss on the cheek.

Cozy naturally detested such affection. Her parents were smart enough to stop doing that to her by the time she was three. “Stupid Twilight, stupid diapers, stupid everything!” She grumbled as she spelled “Twilight is dumb” with her blocks.

She eventually got bored of that and moved onto playing with her dolls, the very same dolls she’d taunted Chancellor Neighsay with. She grabbed a tiny cloth and put it on the Twilight doll, imaging it was a diaper. “Look at me, I’m Twilight. I’m a big, dumb pony who had to stop Cozy Glow instead of letting her take over the world. I’m such a poopy head, I have to spoil everypony’s fun.” She pretended to take her anger out on the dolls and made them fight each other.

Starlight simply observed the whole thing with frightening concern. Cozy’s anger seemed to be getting worse and not better. “Well…. She's definitely still a little sore about losing, not that I blame her. But I’m sure she’ll get over it eventually, right? I did, and so did Trixie. Ooh, I got it! What If I give little Miss Fussy Pants a surprise tickle attack? That’s a sure fire way to get her to stop being so mean and nasty.” She thought, not realizing Cozy Glow was trying her hardest to hold in her bladder.

Starlight sneakily trotted up the playpen and when she a few feet away from Cozy Glow she used her magic to pull the target close and began her tickle attack! “Surprise! You should’ve been watching your surroundings, Cozy Glow, because now you have to deal with a new monster…. The tickle monster!” She said proudly as she tickled Cozy all over her little body.

Cozy Glow was unable to do a thing. She just kicked her legs, failing to hit anything. “Hey! Get off me, you idiot! You’re gonna make me pee!” She protested even as she couldn’t help but laugh as Starlight started tickling her. Naturally, holding in her pee became a lot more difficult as a result. She held out at first, but then happened to notice Starlight levitate a feather. When she was tickled with said feather, her bladder was unable to hold any longer as she let out a huge surge of pee into her diaper! Her laughter was interrupted as a steady hissing sound could be heard!

As Cozy’s diaper became full, Starlight finally got off her. When Cozy got up, her diaper sagged. “What the- Great job, Starlight you idiot! You made me pee my diaper, and I’m not even a foal! I’m so peeved!” She growled as her eyes narrowed, before Starlight grabbed her by the hoof and led her to the nursery, with Spike following them.

“First off, you are a foal until the punishment is done. Secondly don't call ponies idiots, that's not very nice. And three, if you dare to say such naughty words in front of Twilight or I anymore, I’ll have to scrub that dirty mouth of yours with some soap! Applejack and Rarity told me they did all the time when they raised their younger sisters. And even Pinkie Pie had her mouth washed out a few times growing up on the rock farm. The Pies are very strict about discipline, be thankful I’m not like them,” Starlight scolded as she placed Cozy on the changing table and got a fresh, new diaper for her, this one had tiny, little purple hearts printed on it for wetness indicators. “Now, let's change the grumpy foal. We wouldn't want you getting a rash, would we? Twilight definitely wouldn’t like that.”

“Just shut up!” Was all Cozy said as Starlight prepared the stuff. Deep down she wanted to cry, but that would show weakness. Instead, she just laid there. “Wait… I’ve got an idea!” She thought with a grin. “When Starlight removes the diaper, I can make a run for It and escape! Those poofy diapers have been holding my wings down, so with them off I can get out of here without a problem!” And so she waited for Starlight to remove the diaper so that she could set her plans into motion. They were going to regret ever thinking they could get away with humiliating her like this.
