For Science

“Mohohohohohore! Mohohohohohohore!” Pinkie squealed, twisting and turning her hips as much as she could, but the straps wouldn’t let her budge far.

“Pinkie, I’m almost at the maximum setting, are you sure?” Twilight warned, looking over at the machine readings. Pinkie’s heart rate was naturally high, the stress she was putting on her restraints wasn’t going to break anything anytime soon. Nothing too out of the ordinary, but she still felt the need to be cautious.

“Do it do it doohoohoo ihihihihit!” Pinkie challenged, a manic glint in her eye.

The pony was currently laying on her back, spread eagle on a table down in Twilight’s basement. Pill vibrators were attached to her armpits and soles, buzzing at such a high frequency it seemed specifically made for tickling instead of pleasure.

Twilight and Pinkie were spending the afternoon experimenting. At Pinkie’s request, she wanted the kind of experiments that got her tickled. Something that Twilight was more than happy to accommodate.

The kinds of things they experimented on were fairly standard: Which pegasi’s feathers tickled more? Did baby oil or lotion make feet more sensitive to hairbrushes? Is Pinkie’s left foot or right foot more ticklish?

After extensive testing, they discovered: Fluttershy’s feathers, Rarity’s secret pampering lotion, and inconclusive, will need several trial runs to provide a more definitive answer.

Twilight was pleased to use hard data in order to have objective facts for this fetishistic interest. Pinkie was just happy with an excuse to get tickled all day long.

Their current experiment being conducted was trying to determine if pill vibrators tickle more on Pinkie’s soles or her armpits. Both were proven to be highly sensitive spots on Pinkie. Even through casual observation, whenever she was tickled on either spot, she would almost certainly start squealing in hysterics.

Pinkie, being at the receiving end of all the tickling, was thought to be the best judge of what was tickling her more. But as the vibrator’s slowly increased in levels of intensity, her choice kept swapping.

And from Twilight’s perspective, Pinkie’s constant changing of her mind was consistent with the data. Whenever she claimed the vibrators were tickling her feet more, she was kicking far more frequently, adding stress to the ropes at her ankles. When it was tickling her armpits more, she pulled her arms down, reflexively trying to protect her pits and straining the higher pair of ropes.

Still, there was one more setting to go, and both mares were curious to what the results were going to be.

Only one way to find out.

Twilight clicked the remote, making all four vibrators buzz at maximum speed. As their whirring pitch got higher, so did Pinkie’s squealing.

“NAAAAHAHAHAHAAHAHAAAAHAHA!”

“So, Pinkie…” Twilight said, picking up her clipboard, trying not to enjoy the sound of Pinkie laughing her head off too much. “Where does it tickle more? Your armpits, or your feet?”

“EEEHEEHAHAHAHAHAHAHAHAHA!” Pinkie’s response was a burst of laughter and shaking followed by a loud snort.

“Mm, that’s fair,” Twilight dryly noted, scribbling something down. “Just let me know when you’ve made a decision.”

Pinkie rolled her head, squeaking and snorting as the laughter kept pouring out. She wanted to tell Twilight which one tickled more, but it was so hard to decide! She bucked and jumped, her toes curled and her fingers splayed out helplessly. “AAAHAHAHAHAHAHA! T-THEY BOHOHOHOHOTH TIHIHIHIHICKLE SOHOHOHO MUUUUCH! C-CAN I SAY BOHOHOHOTH?”

Twilight glanced over at the machine, looking at the hard data. It seemed Pinkie wasn’t just being indecisive. Her wrists and ankles were both struggling at roughly equal measure. There was a bit of variance, but nothing truly significant enough. “Fascinating…both it is!” She made a quick little scribble on her clipboard before grabbing the remote.

Pinkie’s eyes widened, trying to reach over to Twilight. “W-WAHAHAHAHAHAIT! DOHOHOHOHON’T!”

Twilight looked over at Pinkie, raising an eyebrow. “What, you changed your mind?”

“NOHOHOHO! I JUST DON’T WANT IT TO STAHAHAHAHAHAHAP!”

With a soft chuckle, Twilight playfully rolled her eyes and set the remote down. “Alright, I guess I can wait and see if there’s anything that might happen to change your mind…” She said, making up an excuse to let the tickling continue.

“EEEHEEHEEHEEHEE!” Pinkie squealed in delight, wiggling around as the vibrators buzzed on her tickle spots. Eventually, she started to get used to the intense buzzing, and her struggling became less frequent. She still twitched and squirmed, but there was less violent jerking. All her wiggling was purely from the enjoyment of her ticklish predicament.

Twilight smirked as she looked at all the notes she took so far. All of it was fantastic data, and certainly would be something that would come in handy later. Especially at something like, say, a tickle fight at an upcoming slumber party this weekend.

“OOH! TWILIHIHIHIGHT! TWILIHIHIHIGHT!”

“Yes, Pinkie?”

“P-PUT IT ON MY TOHOHOHOES NOW!” Pinkie suggested. “I WANNAHAHAHA SEEHEEHEEHEEHEE IF IT TIHIHIHIHIHICKLES MOHOHOHORE!”

“I dunno, Pinkie,” Twilight smirked as she turned the vibrators off. “Your armpits have probably gotten used to all the tickling by now, it wouldn’t be a fair trial that way.”

She walked over to gently remove the tickle tools from Pinkie’s body. “Plus they were about to run out of power anyway.”

“Awww! Boooo!” Pinkie jeered and pouted, though she couldn’t even pretend to be upset for long, she was having too much fun. “So! What’s next, Twilight?”

Twilight briefly flipped through her notes. “Hmm, I don’t know, Pinkie. We went through a lot today.”

“Aw, come on! You don’t have aaaanything else in mind?” Pinkie batted her eyelashes, looking at Twilight with puppy-dog eyes.

Twilight could feel her heartstrings being tugged at, and yet she couldn’t bring herself to look away. “Fine! I’m sure I can come up with something!”

Pinkie gasped in excitement, wiggling her hips to show her happiness. “Yay! Ooh, maybe you could try a tickle spell!”

“Tickle spell, hm?” Pinkie’s suggestion got Twilight’s gears turning. Come to think of it, there was something along those lines she could do. It was a long while ago. Something Princess Celestia performed on her plenty of times to tease her. She had only done the spell herself only a couple times. But this would be a perfect opportunity to practice casting it…

“...I think I have an idea, just give me a moment to prepare it,” Twilight untied the knots around Pinkie’s wrists and ankles so she could have proper time to rest.

Pinkie quickly sprung up, wiggling her toes in excitement. “Eee! I can’t wait!”

Twilight briefly left the basement, needing Spike to send a quick letter and hope that Celestia wasn’t reading her messages aloud in public.

Thankfully, Twilight wasn’t gone too long, and she returned to the basement with a scroll in hand. “Alright, Pinkie. This is a tickle spell made by Princess Celestia and Princess Luna themselves!”

“Oooh, really?” Pinkie leapt off the bondage table, yelping due to the oversensitivity of her soles as she bounced her way to Twilight, trying to get a good look at the scroll. She kept bouncing, pushing herself off on her toes to prevent pressing her tired and tender soles into the cold floor.

“W-Well…I just know that they use it…like…a lot…” Twilight said as her cheeks got redder. “But, how about we give it a try and see how much it tickles compared to all the other stuff we did today?”

Pinkie quickly bounced back to the table, eagerly wiggling her toes. “Sounds like a plan!”

“Alright, keep your feet together, Pinkie,” Twilight commanded. “It’ll work better if I can cast the spell on just one area.”

Pinkie did as she was told, sitting up straight and keeping her feet together in front of her.

Just as a precaution, Twilight added some straps to keep Pinkie’s feet secure, wrapping them around her ankles and her thighs. “Is that good? Not too tight?”

Pinkie did a few test kicks and wiggles with her legs to see. Not that she was expecting to break out, but even being tied down had its perks. She was pretty snug in place. She couldn’t move her legs apart, but she could still flex and curl her feet to tease Twilight. “I’m all snuggled up!”

Twilight’s gaze was focused on the straps to see any signs of wear, but the moment Pinkie started wiggling her feet, it immediately caught her attention. Her cheeks started glowing red as she couldn’t tear her eyes away from those blushing soles.

“Twiiiiiliiiiight…” Pinkie giggled, spreading out her toes and waving to her with her feet.

“Hm?” Twilight absentmindedly asked, still transfixed by Pinkie’s soles.

“Aren’t ya gonna cast the tickle spell?” Pinkie smirked, lifting up her legs and booping her on the nose with her big toes.

“Huh? O-Oh, right! Ehehe…” Twilight sheepishly chuckled, hiding her embarrassed blush behind the scroll as she read it one more time.

Pinkie saw Twilight’s horn start glowing with her magical aura, her toes wiggling in excitement as she waited for the tickling to start.

“Alright, I can concentrate this spell on a specific area, Pinkie. Where do you want to be tickled first?” Twilight asked, her horn at the ready.

“Oooh! My toes! Tickle my toes!” Pinkie eagerly pointed to her wiggling toes over and over, bouncing up and down on the table.

“Okay, okay! Your toes it is! Just hold still or I might mess it up!” Twilight chuckled. Pinkie Pie’s giddy exuberance was far too infectious for her own good.

Pinkie stopped rocking the table, but she could barely stop trembling and giggling in anticipation.

Twilight looked down at Pinkie’s toes, focusing her magic on them, and trying not to get too distracted by how cute and pudgy they were, especially with Pinkie curling and wiggling them like that.

As Pinkie watched Twilight’s magic aura start to envelop her toes, she was already squeaking trying to imagine how much it was going to tickle. Would it start out slow and build up to the good stuff? Or would it be super intense from the get-go? Would it start at just one toe and slowly spread to the rest over time? Maybe after that, it could spread to the rest of her feet, and then maybe make its way up her entire body! Now that would be fun!

Of course, now that she was thinking about it, Twilight mentioned before that this was a spell that the princesses used. And she blushed super hard when she said it, too. That totally meant that they used this spell on her before. That’d be so cool to see! Two princesses with super powerful magic tickling Twilight at the same time. Oh, she must have been squealing super-duper hard when they did it.

The aura surrounded Pinkie Pie’s toes, staying there after Twilight’s magic faded from her horn. Pinkie watched and waited for the tickling to start, leaning in to watch her feet as close as she could.

As the magic on Pinkie’s feet started to fade as well, the two waited for the spell to take effect. Precious seconds ticked by, all without tickling.

Twilight took another look back at the scroll, trying to see if she performed the spell wrong somehow.

Pinkie’s eager grin slowly faded with every second passed that she wasn’t getting tickled. “Um, Twilight? Did Princess Celestia send you the right-WOOOAAAAAH!”

Startled by Pinkie’s shout, Twilight looked up from the scroll, rushing over to her friend’s side. “Pinkie? What happened?”

Pinkie’s smile quickly returned to her face as she watched her feet twitch. The twitching turned to trembling. Her eyes widened as she felt something at her toes. It was an all-too familiar tickly sensation. A squeal started building up from inside the earth pony as the sensation got stronger and stronger.

“...Pinkie? Is-”

“AAAHAAAAAAHAHAHAHAAAA!”

Twilight recoiled at Pinkie’s explosion of laughter. She was about to cast the spell again, but perhaps it was for the best that she didn’t.

“EEEEHEEHEE IT TIHIHIHIHIHIHIHICKLES! IT’S TIHIHIHIHICKLING MY TOHOHOHOHOHOES!” Pinkie squealed, pointing at her feet. Her toes were frantically wiggling about.

“...Huh.” Twilight leaned down to get a closer look at Pinkie’s feet. Her magic aura was gone entirely, so it just looked like Pinkie was getting tickled by nothing. “So that’s what it’s like…” she noted to herself. When Celestia was performing the spell on her, she was either on her stomach, or Celestia was sitting on her ankles, so she had no clear view on her own feet.

“AAHAHAHAHA OHMYGOSH IT SUHUHUHUPER DUHUHUHUPER TIHIHIHICKLES!” Pinkie Pie was bouncing on the bondage table, the straps barely keeping her from leaping off. Her toes curled and uncurled as she heartily laughed.

“Oh? How much does it tickle?” Twilight grabbed her clipboard. “On a scale from one to ten, with ten being the most ticklish.”

“T-TEHEHEHEN! EEHEEHEEASILY A TEHEHEHEHEHEHEHEHEN!” Pinkie answered with no hesitation. “AAAAA MAYBE EHEHEHELEHEHEVEN!”

“Mmm, makes sense,” Twilight nodded, writing Pinkie’s answer down. It’s not like she could take it when Celestia and Luna performed the spell on her.

Twilight took another look at Pinkie Pie’s feet. She had never seen her toes wiggle that much while being tickled. Or perhaps she just wasn’t paying enough attention. Admittedly, now that she was looking closer, it was cute to see her chubby toes wiggling about like this.

“NAAHAAAHAHAHAHAHA!” Pinkie threw her head back with wild laughter. Her toes splayed out in shock as another wave of tickly sensations hit her toes. Her legs kept trying to kick, but nothing her legs did would let her get away from the tickling. Not that she wanted to escape, her body just couldn’t help itself.

Twilight might as well ask some questions while Pinkie was still able to answer. “So, Pinkie, what does the tickling feel like? Feathers, brushes, electric-y?” Twilight wanted to see if Pinkie’s answer matched her own experiences.

That question made Pinkie think a bit. As hard as it was with all the tickling. It didn’t really feel like any conventional tool. Not like feathers sawing between her toes, or an electric toothbrush buzzing on her feet, or Rarity’s manicured fingernails scritching against her soles. It was an entirely different sensation entirely. It was hard to describe how it felt, other than…

“HEEHEEHAHAHAHA! I-IT JUST TIHIHIHIHICKLES! IT’S REEHEEHEEALLY TIHIHIHICKLY!”

Now that was an interesting response. To Twilight’s knowledge, she was expecting it to feel like dozens of miniature scratchers on each individual toe. “Hm…are you sure? It doesn’t feel like feathers or vibrators or anything?”

“N-NOHOHOPE! IT’S SUPER DUPER TIHIHIHIHICKLY!” Pinkie responded, though she knew that probably wasn’t very helpful to Twilight. She tried to think of the best way to get the message across. “I-IT’S LIHIHIHIKE! LIKE IT MADE MY TOHOHOHOHOES SO TIHIHIHICKLISH, THE AIR TIHIHIHICKLES!”

Well that was certainly a more helpful way of describing it. Twilight looked at Pinkie’s toes again, still expressive as ever. Her snorting laughs accentuated by a brief splaying of her toes. “Do you think you can stop wiggling your toes so much, Pinkie?”

“I CAHAHAHAHAHAN’T!”

“You can’t?” Twilight tilted her head. “Does it tickle that much?”

“NOHOHOHO!” Pinkie frantically shook her head. “M-MY TOES CAHAHAHAHAN’T STAHAHAHAHAP WIGGLING!”

“What do you mean they can’t stop? Try curling up your toes,” Twilight suggested.

Twilight saw Pinkie’s wiggling toes start twitching. She heard Pinkie let out a long squeal as her toes bent forward, but no matter how hard she tried, she couldn’t keep her toes down for long.

“EEEEHEEHEE! I-I’M TRYING TWIHIHIHILIGHT! I…I THINK IT’S MAHAHAHAKING MY TOHOHOHOES MOVE!”

“You think the spell is making your toes move as it tickles them?” Twilight wondered out loud. If Pinkie couldn’t stop moving her toes on her own, then perhaps…

“Hold on, Pinkie, let me try something.” Twilight put an arm on Pinkie’s ankles for stability, then pressed her palm against the toes of one of Pinkie’s feet.

As soon as Twilight tried, however, she felt Pinkie’s toes wiggling against her hand, constantly fighting back to keep flailing about freely. “Pinkie! Try to keep your toes still, would you?”

“I’M TRYIHIHIHING! IT TIHIHIHICKLES SOHOHOHO MUHUHUHUHUCH!” Pinkie squealed, trying to reach forward and help Twilight hold her toes back.

After a tough struggle, Twilight eventually got all the toes on Pinkie’s foot pinned back, though she could tell Pinkie was still fighting back. Her palm felt all the trembles from the toes trying to push back.

To both their surprise, Pinkie’s laughter died down significantly. She was still letting out a constant stream of laughter, but the earth pony wasn’t screaming hysterically with every breath.

“H-Hehehehey! It doesn’t tihihihihickle as muhuhuhuhuch! Eeheeheeheeheep!” Though Twilight was holding one foot back, her other foot was free to wiggle and flail with ticklish glee.

“So if your toes aren’t wiggling, it isn’t tickling you, huh?” Twilight’s arm was trembling. Even if she wasn’t doing it on purpose, Pinkie’s foot was clearly fighting for freedom.

“Ooh! Thihihihis is fuhuhuhuhun! It’s super tihihihickly ahahahahall the time!” Pinkie giggled.

“If that’s the case…” Twilight thought out loud. “Then I wonder…” She pulled her hand back, allowing all of Pinkie’s toes to move freely.

Pinkie’s eyes widened in surprise as she felt her toes move again, and the intense laughter came pouring back out. “AAAAAHAHAHAHAHAHAHAAAA!” She snorted and howled with laughter. The sudden spike in tickling caught her by surprise, and she laid backwards on the table, pounding her fists she squirmed on the table.

“Fascinating!” Twilight grinned, writing down more notes. And here she thought that the spell merely tickled the daylights out of her when Celestia cast it.

Now that she was recalling old memories, after Celestia cast the spell on her feet, Twilight kept kicking and thrashing around in a vain attempt to lessen the sensations. Celestia never tried to hold her ankles still or restrain her legs, she just commented on how adorable she looked while struggling and squealing. Twilight thought she was just kicking out of instinct, but it was all that flailing her feet were doing that caused her to laugh so much.

Pinkie tried to sit back up to watch her feet dance, but every time she tried to lean forward to get upright, she’d just get too overwhelmed by the tickling at her toes and fall back down. Eventually, she just gave up and laid on her back, holding her head and laughing as Twilight’s spell worked its magic.

Twilight finished jotting down the last bit of her notes. “Alright Pinkie, I think you need a break.” Her horn began to glow as another magic aura surrounded Pinkie’s toes.

Pinkie Pie didn’t hear or see Twilight do anything, but she took notice of the fact that the tickling sensation was dulling, and she was regaining control of her toes. Her frantic laughter slowed to a lingering giggle fit, holding an arm on her forehead as she let the last few laughs out. “Eeeheeheeheehee…hahahahahaha…aaaah…”

Twilight gave Pinkie Pie a moment to breathe and take the time to get her thoughts straightened out. Even for a mare that loved getting tickled more than anypony she knew, that must’ve taken a lot out of her.

Pinkie eventually stopped giggling, at least involuntarily. She smiled in contentment, finally able to sit back up straight again.

“So Pinkie, how was the spell?” Twilight picked up her clipboard, readily tapping the quill to the parchment.

“Oooh, that was so much fun!” Pinkie was already clapping and hopping in place, bouncing her butt against the table. “Cast it again! Cast it again!”

Twilight softly chuckled at Pinkie’s excitement. “Hold on, Pinkie. I gotta perform a few follow-up questions first. It doesn’t tickle anymore, does it?”

“Nope!” Pinkie briefly flexed her toes. “Don’t even feel the usual tingles!”

“Interesting…” Twilight lightly pinched Pinkie’s big toes, manually wiggling them back and forth. “What about this, does it tickle?”

Pinkie shook her head. “Uh-uh!” Pinkie wiggled the rest of her toes to prove it. She was grinning from ear to ear, but not laughing.

“Hmm…” Twilight jotted a few more notes down. “Ok, Pinkie. If you really want, I can cast the spell again. Just keep your feet still and-”

As Twilight’s horn started to glow, Pinkie interjected. “Oooh! Wait wait wait! Cast it on my tummy this time!”

“Your stomach, hm?” Twilight pursed her lip. Celestia had only cast the spell on her feet, if it were cast on someone’s stomach, what would it look like? What would it feel like? “Alright, let’s give it a shot!”

Pinkie eagerly lifted her shirt up, exposing her chubby belly. “Whenever you’re ready, Twilight!”

Twilight readied the spell again, this time, aiming at her stomach. Her magic aura surrounded Pinkie’s midriff, covering her from just below her ribs to just above her hips.

As the magic faded away, Pinkie let her shirt drop. Now that she knew what was about to happen, she was all the more excited for it. Her whole body was trembling from anticipation, until finally…

“EEEEEEEEHEEHEEHEEHEE!”

Pinkie arched her back with a jovial squeal, falling back on the table as she shook her hips from side to side. “Y-YEHEHEHEHES! TIHIHIHIHICKLE MY TUHUHUHUHUMMY!”

Twilight watched Pinkie squirm around. Her feet were mostly still, though Twilight noticed Pinkie curling and uncurling her toes. Her upperbody was where all the action was happening. Since she didn’t tie anything above the waist down, Pinkie was rolling and shaking all over the table, while her legs stayed snugly wrapped up in front of her.

Though it did make Twilight curious. If the spell made Pinkie’s toes wiggle around, if she cast it on her belly…

It seems Pinkie was just as curious as Twilight was, as she lifted her shirt back up to see what the spell was doing to her stomach.

Twilight wasn’t quite sure what she was expecting, but it was certainly a sight to behold.

Pinkie Pie’s chubby belly was wiggling and quivering, far more than what was to be expected from ordinary belly laughs. Of course, thanks to Pinkie laughing up a storm and thrashing around, she was probably making her belly move around more.

Pinkie was absolutely elated. Her stomach looked just like how it felt when she was super hungry, except this time it was tickling her instead of making her crave cupcakes.

Twilight kept looking back and forth between her parchment and Pinkie’s jiggling belly, writing as much as she could down before she ran out of ink or the quill snapped. The way Pinkie’s stomach moved about was strange and oddly hypnotic in a way, yet it weirdly seemed natural just because it was Pinkie Pie.

Meanwhile, Pinkie clutched her sides and squeaked with laughter. It had only been a few minutes, but all the tickling was starting to wear on her endurance. Her cheeks had a heavy blush that showed even through all the pink, and tears were flowing freely down her cheeks. “AAHAHAHAHAHAHA! OOOHOOHOO IT TIHIHIHICKLES!”

Though she never wanted it to stop. She’d never dare ask for the fun to end. Pinkie simply hugged her sides and kept rolling around, letting the magic tickle her silly.

With the spell still being untested on parts that weren’t feet, Twilight decided to cut the experiment early. Her horn lit up and took the tickling sensation away, despite Pinkie’s constant bouncing and rolling making it difficult for her to do so.

Pinkie rolled onto her back, groaning in disappointment as the tickles went away. “Awww, it was getting to the good part!” she pouted. “Can’t you do it again, Twilight?”

“I don’t know, Pinkie, we’ve been doing this for a while without a break…” Twilight explained. “Plus we don’t know what it’ll do if-”

“Pleeeaaaaase? It was so so so so much fun!” Pinkie gazed at Twilight, fluttering her eyelashes and whimpering like a puppy. Her toes also got in on the begging, wiggling and flexing if Twilight decided to sneak a peek.

Pinkie was lucky she was so cute.

“...Fine.” Twilight sighed, casting the spell on Pinkie’s toes, rolling her eyes and smiling as her horn lit up.

“Eeee! Thank you thank you thank you thAAAAHAHAHAHAHAAA!”

Twilight smirked as Pinkie erupted with laughter. As she watched Pinkie’s toes dancing again, she was starting to feel envious. Why let Pinkie have all the tickle fun?

Pinkie was confused when she saw Twilight walking away, but her eyes lit up with excitement when she saw her return, sliding another bondage table right next to her.

Mirroring Pinkie’s situation, Twilight strapped her ankles and legs together, keeping her feet in front of her. She stuck out her tongue, concentrating the magic on her own toes.

As the magic aura disappeared, Twilight waited, wondering if she’d have the same explosive reaction that Pinkie did.

“GYAAAAAHAAAAHAHAHAHAHA!” A sudden tickling sensation washed over all Twilight’s toes at once, making her leap and spread out her wings in shock. She looked down at her feet, her toes were splaying and curling and wiggling as much as they could. Now that Twilight was getting a taste for it herself, she was starting to understand Pinkie’s answers better. It was like her wiggling toes were tickling herself, and she couldn’t stop them from moving.

“EEEK! IT TIHIHIHIHICKLES! I-IT REHEEHEEHEEALLY TIHIHIHICKLES!”

“RIHIHIHIGHT?”

The sensation was intense, though it didn’t feel similar to the times Princess Celestia used the spell on her. Perhaps there was a reason for the disparity? Was it different between casters? If she taught the spell to Rarity or Trixie, would it feel different? Was it different because she was only focusing on the toes?

All these questions started to pop up in Twilight’s head, and yet she didn’t care to answer any of them. It tickled too much for her to concentrate on finding any answers or write any information down.

“P-PINKIEEHEEHEEHEE! MY TOHOHOHOES! EEHAHAHAHA!” Twilight squeaked and danced around in place as her toes twitched and curled.

“HEEHEEHEE! L-LOOK AT THEM WIGGLE!” Pinkie watched Twilight’s expressive feet squirm and shake as she laughed right next to her.

“AAAHAHAHAHA! OH NOHOHOHOHO!” Twilight couldn’t keep herself up, she leaned over onto Pinkie’s table, falling onto her for support.

The two ticklish mares hugged each other tight, watching their toes curl and dance as their wild, unrestrained laughter echoed throughout the basement.

Hopefully, the spell would wear off in time like Twilight planned so she’d be able to get Pinkie Pie out when they were done, or at least let her have enough concentration to undo the spell herself.

If not, then she’d have to hop over to Spike and hope that Princess Celestia wasn’t too busy.

There were worse ways she could be spending the day with Pinkie Pie, at least.
