"Mom!" Called Diamond Tiara from her room. "Have you seen my saddlebags anywhere?"

Thanks to her mother's position on the school board, Diamond's absences from the past two weeks had already been excused. She had been registered as sick for most of it. Unfortunately, that luxury only lasted so long and starting today she would have to go back to attending class. It was already a miracle that the whole Silver Spoon incident a few days ago had ended well so she did not want to take any unnecessary risks that could raise suspicion.

Diamond looked under every blanket, scoured through every drawer, and even checked among the numerous empty diaper packages that were strewn around the room. She was searching for her missing school saddlebags. Last she could remember they had been sitting in her closet with her diapers but now she couldn't find them anywhere.

As she moved around, the wet diaper she had been wearing during the night sagged down between her rear legs. She had woken up late for school, having forgotten about it entirely, and was too busy searching to change and shower. The crinkling and squishing of her diaper would be pretty loud to most but Diamond Tiara was used to it and barely even registered the sounds. At the same time, her special magic amulet remained around her neck, feeling lighter than a feather despite its size.

"I left you saddlebags by the front door for you sweetie!" Her mother called up from the kitchen downstairs.

Bursting out of her bedroom, Diamond trotted quickly downstairs. Just as her mother said, there her saddlebags were, sitting on the floor just to the left of the front door. They also appeared to be already packed up for school today. Diamond didn't remember ever having Spoiled do that...

Running over, Diamond quickly picked up and threw her saddlebags onto her back before fastening the strap firmly around her barrel. She had just been about to throw the door open and leave when her mother spoke up from behind her.

"Hold on, master, I must insist that you eat somthing before you go." She said, stepping into the hall from the kitchen while carrying a plate. The plate had two pieces of toast and a small glass of milk balance on top of it. "After all, It's never good to learn on an empty stomach."

Not having any time to argue, Diamond quickly snatched the two pieces of toast off the plate, stuffing them down her gullet as fast as she could. Grabbing the small glass next she downed the entire thing in one swing. Taking a napkin that her mother held out to her, Diamond wiped her mouth before turning to run out the front door. She was already pretty late for classes but hopefully, she could make up some time.

"Have a good day at school, master." Spoiled called out to Diamond Tiara as she sped towards the metal gates in front of their home.

Peeking out the front door, she watched as her daughter slipped through the gate and then rushed off down the street. Spoiled Rich sighed happily as her vision remained firmly focused on her master's behind and the sagging diaper that was still around it.

'Hmm, she must have forgotten that she still had one on...perhaps I should have told her. Then again I suppose it's for the better...she will need it. I certainly do hope she enjoys the special surprise ingredients that I took the time to add to her breakfast.' Spoiled thought, grinning as she wondered how many new ponies would surely be added to her master's collection today...

Diamond Tiara was eventually forced to slow down to a quick trot as she got tired of running halfway to the school. As she passed through town, she constantly stared down at the ground, contemplating things. All the while, she failed to notice the odd looks and stares that passing ponies would give her, as well as the wet crinkling that was coming from her rear. Not many ponies were out and about this early in the morning but there we a fair few.

'Something is definitely up with mom.' Diamond Tiara thought.

Ever since the very close call with Silver Spoon, her mother had become even more...independent. She no longer needed any orders to perform activities and would even surprise Diamond with her forward thinking. Her saddlebags had been a perfect example of this, already packed and ready by the door before she even woke up. Diamond wasn't even sure if she had actually told her mother that she was going to school today.

Before she had used her own magic from the amulet on Silver Spoon, Spoiled had been about as independent as her father was now. But now? It barely even seemed like she was even under the effects of the amulet at all. Just about the only tell that gave it away was when her mother would occasionally call her 'master', but even that had been getting progressively more uncommon.

Curious, Diamond had also asked her mother if there was a way that she herself could cast the variation of the amulet's spell used on Silver Spoon. Her mother had eagerly obliged, and it turned out to be fairly simple. Should she ever want to enchant somepony with that specific version of the spell, all she had to do was say a different chant. This would result in the target being made to be completely okay with whatever Diamond Tiara did rather than make them her slave. Based on Silver Spoon's behavior it seemed like it also encouraged them to 'join in' but she wasn't so sure.

Evidently, those already under the spell's effects didn't need to do the chant as they were apparently already filled with the amulet's magic. Unfortunately, there was a side effect of using this alternate chant, namely a sudden and very urgent need to use the bathroom, as was demonstrated by her mother after she had enchanted Silver Spoon.

Right now though, the last thing Diamond Tiara wanted to do was make things even more complicated by using the amulet on more ponies. If she kept doing it, eventually somepony would have to find out what was going on. Who knew what might happen should one of the princesses found out! Diamond made a mental note to keep as far away from Twilight's castle as possible. She couldn't really explain why, but something in her chest told her that it would be bad if the purple alicorn spotted her wearing the amulet...

*Grumble*

Diamond Tiara's stomach groaned as she began running again, her stomach growling as it started digested her breakfast. For some reason, something about it felt weird but she decided it was probably nothing to be worried about...

Heat Riser growled angrily as he sat on a lone stool outside the front door of Ponyville's schoolhouse. He had been sent outside and told to sit here for 'misbehaving', again. He didn't think what he did was worth being put in time out but evidently just touching the teacher's flank with the eraser end of his pencil was somehow akin to murder. Worse yet, apparently Cheerilee was planning on talking to his parents about his 'unacceptable behavior' after school today.

'It's not my fault she was practically shoving her flanks in my face! How was I supposed to resist? I'm just a young stallion!'

Cheerilee had been helping another filly in the desk to his left and her flank was pretty much directly next to his face. Unfortunately for him, her tail was down in just the right spot to cover up anything worth seeing. He tried to carefully push her tail aside with the end of his pencil but then she decided to back up slightly. His pencil ended up jabbing forwards and going through her tail. He wasn't sure what he apparently hit but Cheerilee had certainly reacted pretty dramatically.

Heat let his head lay back against the schoolhouse wall, groaning as a wave of boredom began to creep up on him. He felt tempted to sneak off and hang around on the playground, but if he was caught, his punishment would probably just get even worse. Then again, he was sure to die of boredom if he just sat here for the rest of class. The school day had practically just started and wasn't going to end for at least another few hours.

Just when he was about to try and sneak off, some movement caught his eye, making him scramble back onto his stool. Squinting at the source he saw a filly coming up the path to the schoolhouse. He raised a hoof over his eyes to get a better look at who it was.

'Diamond Tiara?'

He was surprised, she had not shown up to class for at least the past two weeks. Still, it pretty much had to be her. There was a line of bushes in the way but her head still stuck out over them, as did the signature tiara atop her head. While this was only Heat's first year of school here since moving to Ponyville, he had already heard all about her. Apparently, she and Silver Spoon used to be big bullies but have since turned over a new leaf.

Regardless, he watched as the filly make her way up the path until she passed by a gap in the hedge-like bushes. Performing a double take, for the brief moment her full body was in view, he could have sworn she was wearing something white and poofy around her rear.

His attention now fully drawn, he watched as Diamond Tiara approached the final turn in the path. Then, as she rounded the corner, his eyes widened as he confirmed what he thought he saw. She was wearing a diaper. He had to stop himself from bursting out laughing at just how ridiculous she looked. She was even waddling slightly as she trotted along.

As he was covering his mouth with a hoof to cover up his smile she seemed to finally notice that he was even there. Upon seeing her look at him with a questioning look he struggling to keep his cool. She didn't appear to realize where exactly on her body he was looking.

It wasn't until she got up to the bottom of the front steps to the schoolhouse that he noticed something else about her diaper. It was sagging down between her back legs and was noticeably tinted yellow. She had wet her diaper too!

Diamond Tiara stared at the strange colt sitting on a stool by the front door of the schoolhouse with a raised eyebrow. What was his problem? He seemed to be having a fit or something. She remembered him as being a new colt that had moved to ponyville this year. She didn't know much about him other than apparently he had a tendency for getting into trouble.

Diamond rolled her eyes as she made her way up the steps and to the front door of the schoolhouse. Whatever he was laughing about, it was probably about something that had gotten him into trouble in the first place. Sure, she hadn't been to school in over a week but what was so funny about that? Rolling her eyes, Diamond lifted her hoof to the doorknob, turned it and pushed open the door. She was instantly met with an irritated sigh from Cheerilee.

"Heat Riser, I already told you, stay outside or- Oh!" She gasped upon notice Diamond Tiara in the doorway.

Suddenly there was a wave of murmuring and a few giggles from many of the foals and fillies in the classroom. Diamond Tiara looked over to see what was so funny only to find some of them staring or pointing at her.

"Um...welcome back, Diamond Tiara...uh, I hope you'll feel better soon." Cheerilee greeted awkwardly, giving her a nervous smile for some reason.

'What is with everypony today? Why are they acting so weird? Did something happen while I was gone?'

"What do you mean Mrs. Cheerilee?" Diamond Tiara asked, hoping for some sort of explanation as to what was going on.

"Well, I just figured that- you know what never mind...You can go take your seat." She said, pointing her hoof at the empty desk in the middle of the room.

Looking in that direction she found a few students were still giggling to themselves but had quieted down after Cheerilee threw a glare their way. Diamond was able to spot Silver Spoon sitting amongst them but she seemed almost as confused as Diamond felt, looking around at the others with a raised eyebrow.

Diamond Tiara awkwardly made her way through the desks, climbing up into hers and sitting down. As she sat Diamond was surprised at just how comfortable and cushiony her desk felt. She took off her saddlebags and put them down next to her desk. There were a few more giggles from the class until Cheerilee was able to get things back on track.

"Ahem! I'm sure Diamond Tiara doesn't appreciate of all of your attention. Why don't we get back to what we where learning hmm?" She said, finally silencing the rest of the classroom.

The next few minutes went by fairly normally, though there was still the occasional giggle or bout of laughter from a few different students. It wasn't until about thirty minutes later that somepony poked at her side to get her attention. It was Silver Spoon.

"I don't get why everypony is laughing and staring at you, did you do something silly?" She whispered, trying not to draw Cheerilee's attention as she wrote on the board.

"I don't know, everypony is being weird! Is this supposed to be some kind of cruel revenge for bullying them in the past?!" Diamond Tiara whispered back.

"I guess, after all, what's so weird about your diaper? It's not that wet yet." She whispered back.

Diamond Tiara had been about to quietly tell Silver Spoon not to talk about that stuff here when she realized what exactly she just said.

"W-wait, what do you mean?" Diamond whispered, suddenly fearing the idea of looking down.

"Huh? Well-duh, the wet diaper you have on." Silver Spoon answered nonchalantly.

Time seemed to freeze as Diamond Tiara slowly turned her head down. Her heart sunk when she saw the signature puffy padding that surrounded her back legs, currently acting as a padded seat cushion. In addition, it was noticeably yellow in color, clearly having been wet at least three separate times already. Her pupils shrank to pinpricks as she realized something. It was the exact same diaper she had been wearing to bed last night. She forgot to take it off before leaving the house for school!

Diamond Tiara just stared with wide eyes down at her diaper. Everyone in the class right had to be staring at her, everyone she had ever bullied, been mean to, or even recently been friends with was staring and laughing at her. At the same time, it dawned on her that she had likely been seen multiple times while walking through town...everypony would already know that Diamond Tiara wore and used diapers. The secret was out.

"Diamond Tiara?" The concerned voice of Applebloom whispered from her right. "Not meanin ta be rude or nothin but, why are you wearing a diaper?"

Suddenly, an absolutely massive surge of emotion smashed into Diamond Tiara all at once. She felt her amulet growing heavy around her neck and she felt herself being lifted out of her seat. Her eyes slammed shut as she tuned out the rest of the classroom, the unexpected rush of embarrassment and shame becoming too overwhelming. She was unable to hear as the whole classroom gasped as her body began to glow with a green aura, her amulet now giving off an extremely bright light.

"What I doth is n'rmal to thee!" Diamond Tiara suddenly felt herself shout out into the air, her eyelids opening to reveal nothing but a green light behind them. A huge surge of magical energy pulsed outwards from her body, and then all at once, everything went black...

"Diamond Tiara? Diamond Tiara, are you alright?" the voice of Cheerilee spoke, waking Diamond Tiara from a daze.

"Huh? Mrs. Cheerilee? What just happened?" Diamond Tiara answered groggily, rubbing her eyes with her hooves.

Looking around, everything appeared to still be the same. Cheerilee was standing next to her, looking fairly concerned. Nopony was laughing or whispering anymore, in fact, a few of the students looked about as concerned about her as Cheerilee did. Looking down Diamond remembered that she was still wearing her diaper. However, she was then distracted by something else. Her magical amulet was glowing very brightly, just like after she...

"Mrs. Cheerilee?"

"Yes, Diamond Tiara?" Cheerilee asked.

"This might sound weird but...do you believe I'm your master?"

"I'm afraid that I'm not too sure what you mean." She replied.

'Did I? Did I use the amulet again?' Diamond Tiara thought, looking around at the other students.

Now knowing that she was okay, they all seemed much more disinterested in her now, like it was any other day at school.

"Well, as long as you are feeling okay, I'm going to get back to teaching class. Let me know if you need anything Diamond Tiara." She said before casually trotting back to her desk. Diamond Tiara had been about to turn and ask Silver Spoon what exactly just happened when it hit her.

*Gurgle* *Grumble*

She suddenly she felt her stomach twist, causing her to cringe from a very tight sensation in her lower gut. It felt like something huge was building up inside her, growing bigger and bigger by the second.

*Pwwwfwft-Splorfpt!*

Diamond Tiara gasped as she felt a sudden landslide of liquidy sludge start pouring into her diaper. She tried to clench her anus to stop the torrential flow, but for some reason, she found herself unable to provide any resistance at all. More and more poop noisily flowed out of her ponut, attracting the attention of a few of the other students sitting around her. They watched as her diaper expanded and bulged in the back as it continued to be filled with poo.

The brown muck spread out inside her diaper, quickly covering her flanks with a layer of stinky mess. To add on to the rush of brown filling her diaper to the brim, piss freely started streaming from her sex, soaking her diaper even more and mixing with her poop. The hissing and gassy crackling sounds that came from her diaper seemed to fill the entire room, drawing even more attention her way.

"Diamond Tiara, I must request that you try to keep the noise down while you are having an accident in your diaper, I am trying to teach the class," Cheerilee said from up at the board.

'Where is all this coming from?! Is this because I used the alternate version of the spell?'

Despite what she was currently going through, most of the students seemed to eventually lose interest, though there were a few, namely Silver Spoon, that remained firmly glued to her growing diaper. It didn't take long until the amount of mess became too much for the diaper to contain and it began to leak out through the leg holes. By the time the torrential flood of both poop and piss ended, there was a small yellow puddle in her seat and a few dribbles of brown sludge that dripped down her back legs.

Heat Riser could not believe what he was seeing through the schoolhouse window right now. He had found it too hard to resist and wanted to see how the other colts were reacting to Diamond Tiara's diapered situation. What he didn't expect was to see the earth pony suddenly engulfed in a bright aura of green and begin levitating into the air. After which shafts of green magical energy shot into everyone in the building, including their teacher. Thankfully, whatever had happened didn't seem to have affected him outside the window.

After the spectacle ended, Diamond Tiara gently floated back down into her desk, and then after a moment of confusion from everyone, Cheerilee began to approach her, looking concerned. It was then that Heat Riser ducked back down under the window, eyes wide. He had to tell somepony what he just saw!

Author's Note

Finally got around to doing this chapter. Sorry for the delay for all those tracking this. Future updates may be long as well, but more will likely be done for this story.

Also, much like my Soiled Universe series, I have gone back and revised the previous chapters if you would like to go back and check that out. There are a few minor changes that may be worth looking at if you are following this for the story at all.
