Pranks For That

Starlight yawned, putting a hoof over her mouth as she traversed the castle halls. Her nap may have been over, but it would still be a while before she truly recovered from overextending her magic. More rest would likely do the trick, but for now she was just too excited to go back to sleep.

Three hours had passed since her prank had been set in motion. The fifteen minute cat-nap she’d hoped to sneak in had really ballooned, and now she was worried she might have missed everything.

Three whole hours, Starlight thought to herself with a snicker. I bet she’s freaking out right about now!

Of course, there was also the possibility that Twilight had managed to escape the prank already, even though Starlight had put everything she could into guaranteeing Twilight wouldn’t be able to get out on her own. They’d long since proven their power was equal, after all, so that hopefully meant Twilight couldn’t get free without help. But she wasn’t going to bet on that. Who knew how things had gone down so far?

If she missed her chance to catch Twilight diapered then her first prank ever would be ruined. That was not going to happen.

Tired though she was, Starlight picked up her pace to make a beeline to the throne room. There wasn’t even a guarantee Twilight was still there, but it was still the best place to start looking. Besides, while diapered there were only so many places Twilight could go. Starlight would find her eventually.

The tall doors to the throne room came up even sooner than she expected. Starlight’s heart began to beat faster with anticipation. Any more waiting and she risked it bursting out of her chest.

Even with that fact in mind, she still lingered just outside the doorway, ears at attention as she pressed them into the thick door.

crinkle. crinkle. crinkle.

“mmph. mmmrr!”

A near sadistic grin spread across Starlight’s face. Those foalish crinkles were unmistakable, and the same could be said for the struggling grunts that accompanied them.

“Yes!” Starlight whisper-cheered, hoof pumping the air. Her first prank had gone off without a hitch! She hadn’t even missed it.

Her heart may have been racing before, but now it was full throttle. She’d done it! She’d actually pulled off a successful prank. The only thing left to do now was…

Drink in the glory. Starlight’s smile was crooked.

The heavy doors found themselves wrapped in the blue aura of her magic. Starlight threw them open effortlessly, prancing into the throne room with her manic look only growing.

“GOTCHA!” She yelled.

And then Starlight froze, only just now stopping to actually see the result of her prank.

Twilight was suspended in mid-air. Her hind legs dangled a solid three feet from the floor, as a baby bouncer cradled her right where her throne was supposed to be. That alone would’ve been enough to drop Starlight’s jaw through the floor. But what sent her jaw hurtling towards the center of the planet was what Twilight was wearing.

The diaper peeking out from the purple seat of the bouncer was expected, but the matching booties, goofy filly dress, pacifier with straps, and horn ring were most definitely not.

Twilight’s disheveled eyes made contact with Starlight, stirring up a frenzy.

“Mmmhmmph!” She cried, kicking her hind legs and throwing her body forward. She swung the baby bouncer forward, turning herself into a foalish pendulum. “Hmmph mmrr!”

It managed to snap Starlight from her confusion, but still left her with questions. The standard “what?”, “why?”, “how?”, and “huh?” all flashed across her mind as she regained her composure and retrieved her jaw from the hole it’d made in the ground. For a brief second she wondered if Twilight had gotten herself dressed up like this on purpose, but the mare’s repeated struggles and muffled cries for help quickly disproved that.

So then how…? Starlight’s eyelids fluttered with realization. Her spell!

Did the Padded Prison do all of this? She wondered, walking closer to the spectacle before her.

It was the most plausible possibility she could come up with. But if so, how? The Prankopedia hadn’t mentioned anything like this in the spell’s description. All it had covered was just the unremovable diaper.

Well, that and a few lines of red text begging the practitioner not to... overcharge... the spell…

Oh…

“Heh heh,” she nervously uttered, rubbing the back of her neck. “S-Sorry about this Twilight.”

“Mmmrmmrgh!” Twilight angrily kicked her hooves, glaring at Starlight. It hadn’t taken the sharp mare too long to figure out what Starlight had meant by that ‘gotcha!’ earlier, and her apology just now had sealed it. Starlight was in for one heck of a scolding.

“Oh come on,” Starlight grinned meekly, trying to save face. “It’s just a prank, Twilight. An itty bitty little prank.”

“Mmr phrammk?” Twilight twisted in her bouncer, as though trying to hurl herself at Starlight. “Mmh?”

Starlight held up a hoof, silently asking Twilight to take it easy. “Well, yeah. I swear it was just supposed to be the diaper though. All this other stuff was an accident.”

Twilight face flushed even redder all of a sudden. Right as Starlight uttered the word ‘accident’, as if it was some touchy subject.

It was right then that Starlight’s nose detected something that had flown under her radar up until now. The stale stench of urine masked the air around them. Starlight sniffed, nose wrinkling at the smell.

It didn’t take long to put two and two together.

“Oh…” Starlight’s pupils shrank slightly. “You mean you had to…”

“Mmmrph!” Twilight grunted, narrowly missing Starlight’s head with her hind leg. Starlight retreated a few steps after that.

“S-Sorry,” she said, though the curving of her lips betrayed her. Starlight covered her mouth in a pitiful attempt to hide a snicker. Come on, Twilight had actually peed herself! It was too funny not to laugh at.

“Mmr! Mrr mmrph mmr mmh!” Twilight’s face burned, only fueling Starlight’s laughter.

“I know, I know! Just—” Starlight dissolved into bubbly chuckles. She’d forced Twilight to pee her diaper! Just wait until Pinkie got a load of this; it would put all of her pranks to shame for sure!

Twilight’s ears flopped down, face diving a few shades of red deeper. Struggling against her binds, she grunted again. “HMMPH MMR!”

“I will, I will,” Starlight promised through laughs. Looking up at Twilight, she couldn’t help but break down all over again. The dress, those booties, that freaking pacifier! Now that the shock of it all had died down, Starlight couldn’t find this whole situation anything other than hilarious.

Her first ever prank had reduced a Princess into a diaper wetting filly. How could she not feel at least a little giddy at that? The inevitable scolding she was due for this hardly registered in her mind. She just howled, barely remembering to breathe.

“HMMPH MMR!” Twilight repeated again, an extra level of embarrassment-fueled rage in her muffled voice.

“Okay…” Starlight struggled to calm down. “Okay.” It was time she actually got Twilight down. If for nothing else than to see that wet diaper for herself.

She approached the dangling mare again, this time wary of her free hooves.

“How’d you even end up like this, anyway?” Starlight asked, her magic enveloping the baby bouncer to pull it free.

“Mmm…” Twilight’s face scrunched with worry. “Rrm, mmhr mrph mmhr—“

Starlight tugged on the bouncer, but was met with surprising resistance. The bouncer stayed firm; all she did was send Twilight’s diaper into a noisy fit.

crinkle. squish. crinkle. squish.

“Huh.” Must be on pretty tight. Made sense, she’d made that diaper really thick. “Hang on, Twilight,” Starlight said.

“Mmmph!” Twilight cried, fearfully.

“Yeah, yeah, I know you want to get out.” Starlight’s magic gripped tighter. “Just give.”

Yank! crinkle. squish.

“Me.”

Yank! crinkle. squish.

“A.”

Yank! crinkle. squish.

“MMMPH!” Twilight cried as the bouncer finally loosened.

“Sec!” Starlight yelled, pulling with all of her might.

crinkle. squish. crinkle.

POOF!

“Ah!” Starlight fell back as a sudden flash of magic consumed the room. The bright blue light looked strangely familiar, for the two milliseconds she saw it before being blinded.

Her plot hit the floor, the light fading away soon after. Starlight blinked to regain her bearings, fuzzy vision coming into focus on Twilight. The diapered mare had already recovered, as though she had practice dealing with such magical outbursts.

Twilight was staring at her, pupils mere specks in her eyes. A weak whine came from her pacified mouth.

“Geeze, what was that?” Starlight asked, her plot sinking deeper into the floor. It was much softer than she remembered. Her eyes drifted down to see why and she froze up, heart skipping a beat.

She was wearing a diaper.

The fluffy, white garment wrapped around her crotch was reminiscent of the same she’d stuck Twilight in, right down to how thick and poofy it was. She strongly suspected it had something to do with that burst of magic. It made her hesitate to try and take it off, fearing it may not budge if she did. Starlight gave a cursory attempt to move her hind legs, and winced at the sound generated.

crinkle. crinkle.

“Uh… alright.” Her face flushed a little. It only reddened more when she looked up back at the staring Twilight. Now the diaper was on the other flank, so to speak.

But Twilight didn’t seem so too happy about the sudden turnabout. In fact, she seemed significantly more afraid then before.

“Mmmrphmm, mmph mrrm.” Twilight nudged her head forward, pointing with her horn.

Starlight wrinkled her brow at first, unsure of what that meant. But her eyes drifted to the inhibitor ring around Twilight’s horn and she suddenly felt her heart sink.

She tried calling upon her magic, hoping her hunch was wrong. Her horn failed to light. Gulping, Starlight brought her hoof up and felt a thick band around it’s base.

Oh no…

“I-I can fix this,” Starlight sputtered, not even really sure how this had happened in the first place. Twilight whimpered, demonstrating her confidence in Starlight’s abilities.

“I can!” Starlight protested. She struggled to her hooves, gait spread by her new poofy friend. “I just need to… to…”

What could she do?

Her magic was sealed off, she was diapered, and Twilight was still stuck in the baby bouncer, among other things.

Well I could— Her thoughts were cut off by a sudden rumbling in her stomach. Starlight’s ears flopped down as she felt a pressure slowly start to build in her bowels. Oh great…

Starlight looked back at her diapered rear, brows furrowing. All of a sudden she deeply regretted eating all of those Etceteras earlier.
