It was five-thirty, but the Dazzlings weren’t going anywhere.

They were lined up at the front of the classroom. Sonata, hands clasped in front of her skirt as though she’d done something wrong, Adagio with her arms crossed in annoyance, and Aria, hanging her head to try and hide her red cheeks.

One day. They couldn’t make it one day at school before someone found out about their diapers.

Before them, Vice Principal Luna stood with her hands on her hips. Beside her, Principal Celestia, called in to deal with this… unique situation.

The silence in the room was heavy.

Finally, Celestia sighed. “Well, let me see them.”

Aria’s face tightened. She knew what it was the principal meant, but she was not eager to show off her padding again. Thankfully, Sonata was. The girl lifted her skirt, revealing the plain white diaper wrapped around her waist.

Luna’s jaw dropped. “Wait, you too?”

“Uh huh!” Sonata nodded. “We all—”

“Sonata!” Adagio growled through her teeth. But it was too late.

“All of you, then?” Principal Celestia blinked in surprise.

Aria clenched her jaw, but had finally surrendered her dignity. She pulled her skirt up stiffly, exposing her diaper and plastic pants to the principals.

“I see.” Celestia tightened her lip before turning to Adagio. “And you too?”

Adagio glared, but tugged up her skirt and revealed her pampers to the women, and the blue and white striped panties she had desperately tried to use to cover them. “Yes,” she grumbled.

“Umm… okay then.” Celestia seemed to be thinking for a moment.

Luna, on the other hand, was starting to grow red in the cheeks herself. “You can cover yourselves again, girls,” she managed.

Aria and Adagio gratefully dropped their skirts, faces flushed and frustrated. Sonata seemed a little more reluctant to lower hers, but did so anyway. She must’ve been worried they were already in enough trouble as is.

“Can we go now?” Adagio huffed, looking away. As if that would hide her blush.

“Hold on,” Principal Celestia said. “I’m afraid I don’t understand. What exactly is the meaning of this? Why are you all wearing… um… those undergarments?”

“It’s none of your business,” Adagio snapped.

“We aren’t potty trained,” Sonata said.

Adagio stamped her foot, practically shouting through her clenched jaw. “Sonata!”

Vice Principal Luna snorted, not catching herself in time. Aria clenched her fist, absolutely livid. This woman was laughing at them, when not even two weeks ago she’d been their puppet. Life just wasn’t fair.

“O-kay…” Principal Celestia seemed at a loss for words. Granted it was a little difficult to process. If she were just another high schooler, Celestia would’ve been free to laugh her ass off at them. But she was an adult. An authority figure. She had to maintain some sense of compurse. “Well that’s… not part of the dress code, you know.”

Luna cackled, snorting it short when she got a look. Aria groaned.

“Really?” Adagio asked. “That’s your biggest concern here?”

“Well no, I just— I meant—”

“But if we don’t have our diapers we’d end up ruining our panties,” Sonata oh-so-helpfully pointed out.

“Sonata!” Adagio went up an octave with that one.

“I wasn’t suggesting you…” Celestia shivered. “I’m sorry, I’m afraid I’m still processing your, um… unique predicament.”

Adagio returned to crossing her arms, face still boiling from her blush. “Whatever. Can we just go now? Detention’s over already.”

Celestia opened her mouth to respond, but Luna stepped in instead. “Now hold on there. You may be fine to leave, Ms. Dazzle. But there’s still the matter of Ms. Dusk and Ms. Blaze’s little outburst from earlier to deal with.”

Aria groaned again. “Oh come on! I am not staying another hour just because Sonata is an idiot.”

Sonata gasped. “You were the one trying to steal from me!”

“Only because you locked me in my… these things!”

Sonata stuck out her tongue. “Well if you’re just going to be a big baby about it.”

“Enough!” The Vice Principal’s voice bellowed through the room. The bickering girls had to settle down after that, but only Sonata looked particularly ashamed, as though she’d just been scolded by her mother.

Hand in her head, Principal Celestia sighed. “I’m afraid I have to agree with Vice Principal Luna on this matter. Regardless of your, uh… situations, you still broke school rules with your fight. You’ll have to stay for another hour.”

Aria cursed under her breath.

“Uh…” Adagio raised her hand. “Yeah, that won’t work. If I need a…” Her face reddened. “A little help while they’re stuck in here, what am I supposed to do?”

“A little…” Celestia’s face flushed as she realized Adagio was referring to the possibility that she might poop herself. “That’s… well… um…” she was a bumbling mess. In fairness, very little could’ve prepared her for concerns such as these. Aria would’ve been proud of the fact that the Dazzlings were difficult to deal with, if not for the fact that it involved them being stuck in diapers, that is.

“Sister, if I may,” Luna posited. “Superintendent Starswirl did recently rescind the district restrictions on corporal punishments, didn’t he?”

Aria’s eyebrows climbed her forehead. She didn’t like the sound of that.

“He did, but I don’t see what that has to—”

“Perfect!” Luna didn’t even try to hide her grin. “Then I have a solution that will make everyone happy.”

“Really?” Sonata was smiling. Was she really that stupid?

“I think I might prefer more detention,” Aria mumbled.

“Nonsense.” Vice Principal Luna pulled out a chair, sitting herself down. “I don’t expect you to wait any longer if there’s a chance you’ll have an accident.”

By now, even Celestia had picked up on her sister’s plan. “Luna, I really don’t think this will be necessary.”

“I think it’s entirely necessary,” Luna countered. “I was never satisfied with just giving them detention after everything that went down.”

Oh great. So the Vice Principal was holding a grudge against them just because of a little mind control. That made Aria even more hesitant for what was about to come.

Adagio had already taken a step back, removing herself from the whole ordeal. Apparently their truce didn’t cover something like this. At least, so long as her butt was in the clear

And that left Sonata as the odd girl out. “What’s going on?” She asked with tilted-head confusion.

Vice Principal Luna gave her lap a pat. “Come lie down right here, Sonata. I’ll show you what I have in mind.”

“Okay!” The promised explanation made Sonata seem to forget she was about to be punished. She moved almost eagerly to the Vice Principal, laying belly-down across the woman’s thighs. “Hehe! This is kind of fun!” She giggled, kicking her legs in the air.

Principal Celestia just shook her head, but made no move to stop her sister. She even took a step back, resting her hand on a classroom desk as she waited for it all to be over.

“Now, I think ten is fair. How about you, Sonata?” Luna asked.

“Okay,” the idiot idiotically agreed. “Ten what?”

Luna’s response wasn’t spoken. Instead she pulled up the girl’s skirt, exposing her padded rear. In the instant before Sonata could gasp in surprise, Luna’s hand whipped down and smacked exposed flesh.

SMACK!

“Ah!” Sonata cried

“One.” Luna’s attempt at an even voice failed to mask the sadistic pleasure she got from that. Her hand came up again.

“W-Wait!”

SMACK!

“Owie!”

“Two.”

Sonata started to squirm now. The Vice Principal had to delay her punishment just to wrangle the girl’s arms and pin them down against her back.

“Keep struggling and I’ll start my count again,” Luna warned.

Sonata’s kicking legs slowed. Though she had half-managed to fling herself from the woman’s lap, that threat stopped her cold. Already a red mark was forming on the side of her rear.

“Good.”

SMACK! SMACK! SMACK!

Another three, each hitting the same spot. The red mark gained ground against Sonata’s blue skin, and she openly screamed from the pain.

“No more!” Sonata begged as Luna’s hand shifted to the other cheek’s exposed area. “P-Please.”

“Five,” Luna counted. And her hand came down again.

SMACK! SMACK! SMACK! SMACK! SMACK!

“A-AH!” Sonata cried.

“Ten.” Luna released her hold.

Whining in the back of her throat, Sonata pushed herself away from the Vice Principal’s lap. She winced when she stood up. Hands immediately when down to cover her battered behind, the red glowing so bright it could be seen through the cracks of her fingers.

“Oww…” Sonata sniffled, rubbing her backside. “That hurt!”

“Well that is the point of a spanking.” Luna’s eyes turned from her previous victim to her future one. “Aria, come lay across my lap.”

Having seen what’d just happened to Sonata, Aria was not feeling up to experiencing the same treatment. Seeing her fellow Siren waddle back beside her, wincing with each crinkly step, made her think more detention wasn’t such a bad thing.

“I’ll… pass,” she decided. “Another hour here doesn’t seem so bad.”

Principal Celestia coughed behind her. Looking back, Aria could feel her chances at a longer detention slipping away. Celestia’s reluctant, yet firm, look told her as much.

“I’m afraid we just can’t have that,” Celestia said. “If you’re Ms. Dazzle and Ms. Dusk leave and you uh… need to relieve yourself, there will be no one here to change you.” Aria’s face burned. Celestia looked beyond her to her sister. “Unless you—”

“Absolutely not,” Luna cut her off. “I don’t get paid enough for my current job.”

Aria scowled at her. Oh so happy to spank them, but the second things got a little messy and she was ducking away from even the mention of it.

“Aria, just allow my sister to dispense her… chosen punishment, and you may go home.”

Growling in the back of her throat, Aria tried to fight down her reddening cheeks. “Alright, fine!” She threw her hands up in defeat.

So what if it was humiliating? It couldn’t be that bad. Sonata may still be sniffling in the corner, but she was a complete wimp compared to Aria. She was sure she’d be fine.

She lay across Vice Principal Luna’s lap with a scowl. After all, saying she’d be fine didn’t mean she’d enjoy what was to come. Aria felt her skirt lift up, revealing her padded shame once again. She tried to keep her face from glowing red, crossing her arms and looking away.

“Hmm…” Luna gripped the plastic pants for a moment, the lock clinking loudly.

“Hey, watch—iiiiiiiiiittt!” Aria squealed as the Vice Principal suddenly yanked the pants, and her diaper, upward. Padding flooded the Siren’s nethers, bunching up as it ran out of space to move. She was being wedgied while wearing the worst possible underwear imaginable.

“Sorry, just needed a little more room,” the Vice Principal explained. And then her hand came down.

SMACK!

Aria hadn’t realized her wedgie had left so much of her bottom exposed. Even after the first hit, when the sting of the slap set in and her flesh rippled from the impact, she was still more distracted by the padding growing taught between her inner thighs.

“H-Hey!” Aria whined, her face burning. She heard a very Adagio snicker from across the room, but before she could turn to glare her next spank hit.

SMACK!

This time Aria felt it. She felt the pain.

Maybe the first had just been a warm-up, or maybe it had just gotten her rear nice and tender. Either way, when Luna’s hand came down for the second strike, right on the spot where the first had landed, Aria yelped in pain.

SMACK!

A third in the same spot. Tears sprung to Aria’s eyes. She squirmed to get away, but only doomed herself.

SMACK! SMACK!

The two blows were a warning: Don’t move. Aria froze after them, despite the pain radiating from her butt. It only seemed to grow while she stayed still. And then Luna shifted focus to the other cheek.

SMACK! SMACK! SMACK! SMACK!

“AAH!”

Four blows in as many seconds. Aria bit her tongue in half trying to hold back another scream. She couldn’t let herself show weakness in front of these two women.

“Annnd ten.”

SMACK!

Aria cried out, showing plenty of weakness. That last blow seemed to have some extra force put behind it. A little going away present from Luna’s hand to Aria’s butt.

“All done,” Vice Principal Luna said, letting the girl on her lap scramble to her feet.

Aria pushed down her diaper, finally freeing herself from the wedgie the older woman had given to her. It made her wince, as the padding now pressed against her freshly wounded rear. She actually sniffled.

“Well, I think that’s all the punishment you’ll need for today.” Luna looked to her sister. “Unless you had something else for them.”

“I don’t believe so.” Celestia stepped away from the group in the back, while Aria took her place. She was cringing as she waddled, in the exact same situation as Sonata despite her earlier bravado.

The Principal turned to face the three of them, but couldn’t make eye contact with the two battered girls. Her fellow administrator stood, a lot more confident about what had just happened. The smile on her face said it all; she had really enjoyed a little bit of revenge against the Dazzlings. But the hunger in her eyes said more; there was still one left she would’ve like to punish.

But Adagio didn’t rise to the bait, instead crossing her arms and looking away for the time being. Seeing her fellow Sirens spanked must have humbled her a bit.

“We’ll be sure to inform your teachers about you… um… situations,” Principal Celestia declared. “It—”

“Absolutely not!” Adagio jumped in.

Celestia blinked in surprise. “Uh… but surely you’ll want them to understand if you suddenly need to go in the middle of class. I don’t expect you three to need hall passes until you’re… well…”

“Potty trained,” Luna filled in, all too happily.

Celestia coughed. “Right.”

“We’ll handle it ourselves,” Adagio snapped through clenched teeth. She grabbed Sonata’s wrist in one hand, Aria’s in another. “Let’s go,” she growled, pulling them forward.

“I— If you insist…” Celestia relented. She let the girls leave undeterred. After all, it was five-forty. Detention was over for today.

Aria bit her lip, her red race wincing in pain with each step. Her diaper already gave her a little waddle, but now that her cheeks were glowing red it practically forced her to toddle to avoid making the pain worse.

Part of her couldn’t believe Adagio had just passed up an opportunity to make their miserable lives at this school a little bit easier, but she also understood. No way she wanted all of her teachers finding out about their diapers. It was bad enough the Principals knew. If anyone else learned about it, it would only make there school year worse, not better.

“Do we have ice at home?” Sonata sniffled as she rubbed her butt.

“Probably,” Adagio grumbled, still leading them through the hall. Her pace quickened, and the paddled Sirens struggled to keep up. “And quit crying. It was your own fault.”

“Aria started it,” Sonata whined.

“Only cause you—”

“Hey!” Adagio barked, cutting off their bickering. “Both of you just can it until we get home, alright?”

Aria wanted to protest, but she also didn’t want to risk Adagio snapping and trying her own hand at spanking her. Their truce was tenuous enough as is.

She stayed quiet the whole walk home, clenching her jaw through the searing pain that was her backside. It wasn’t easy, that wedgie had screwed up her usual snug padding to the point where it was riding up against her tender rear, but she put up with it all the same. Her rage never did cease, however.

One thing was for sure; she never wanted to get spanked by Vice Principal Luna ever again.

Felt like unloading all the chapters I had left. The 'one a week' schedule was driving me nuts.
