There's a WHATquestria?!

Much like her other self, Twilight had quickly realized that it wasn't going to be that easy to get back to Tittyquestria, and resigned herself to exploring the world around her in the meantime. She was baffled by the notion of a society existing without titty and desperately needed to understand it. Besides, maybe she'd pick up a lead.

She sat with Starlight by the front window of Sugarcube Corner, smiling around at the decor.

Pinkie and Mrs. Cake chattered about something at the counter. It was a slow, late afternoon, with no one else present. They could hear Mr. Cake checking the kitchen pantries and making sad whiny sounds, presumably whenever he found something to be lacking in stock.

"This place is just like home," Twilight sighed, biting into a grape danish.

"Really?" Starlight raised an eyebrow. "How so?"

"Everyone here looks exactly right," Twilight smiled, then lowered her voice to a whisper, leaning in. "We don't dare to cross Mrs. Cake in Tittyquestria..."

Starlight glanced at Mrs. Cake's tremendous undercarriage, wobbling obscenely with the slightest motion of her body, and wrinkled her nose, nodding and whispering back. "We shouldn't talk too much about this in the bakery."

"Why not?" Twilight blinked. "Should we not pay our respects?"

Starlight stared at her, opening her mouth to try to explain why not. She blinked a few times, and then Pinkie and Mrs. Cake stopped talking. The bigger lady smiled at them and walked towards them. Starlight drew herself up with a big smile.

"Is everything alright, dears?" Mrs. Cake fussed over them. "Will you be having anything else..?"

Twilight seemed to bow while still at the table. Mrs. Cake blinked at her with a confused pout. "We are always grateful to you and your bounties, Mrs. Cake --"

"Aaaaah, yeah, I could go for a slice of something," Starlight hastened to talk over Twilight, almost diving over the table to draw attention away from her. "Er, pumpkin pie sounds great." She produced a few bits and set them on the table, sitting back down.

"Oh, that's a very popular choice right now, since Nightmare Night is coming up," Mrs. Cake nodded, accepting the bits and counting them quickly with a giggle. "My, you've memorized our prices?"

"Yes," Starlight admitted with a blush. "You folks have the most important shop in the village, after all. I admit I have a bit of an appetite and might go broke... but I'll be damned if I go hungry with such lovely offers."

"Oh, you flatter us!" Mrs. Cake beamed, waving her off. "Please, dear, be frugal with your money, we're doing quite well. And Twilight, dear, will you be having anything more?"

Starlight stared intently at Twilight, as though trying to beam something into her head. Twilight stared back, uncomprehending, before looking back to Mrs. Cake. "I would not wish to dishonor your work by ordering more than I can eat right now... A blueberry muffin would be great," she settled on. Starlight sighed a hoo of apparent relief and added another few bits to the table with a big smile and nervous eyes.

Mrs. Cake momentarily furrowed her brows, then smiled and accepted. "Right away, dears," she smiled and turned, walking back to the counter. "Pinkie, sweetheart, the girls will need a slice of pumpkin pie and a blueberry muffin. If you'll pardon me, I'll be checking on the twins, be back down in a few minutes..." She headed back up the stairs.

Before her steps had faded away, Pinkie had set down a slice of pumpkin pie and a blueberry muffin on the table. Not having been told who was having what, she had set them down in front of the wrong ponies. She grimaced with a blush as they smiled at her and switched them. "Thanks, Pinkie," Starlight nodded.

"Aye-aye, cap'n," Pinkie saluted with her tongue out, and trotted back to the counter. She then sighed in boredom, leaning on the counter with one foreleg, looking around the inactive shop.

Starlight devoured her pumpkin pie slice with ruthless efficiency and sat patiently waiting for Twilight to finish her muffin. Twilight found it unnerving how Starlight was half-glaring at her. "H-hey, do ya mind?" Twilight mumbled. "I like to savor my muffins..."

"I bet you do," Starlight returned. "I just wanted to make sure I finished first, is all."

"Whhh?" Twilight mumbled through a mouthful of muffin, then swallowed. "Why? It's not a race." Seeing Starlight glancing nervously at the stairs, Twilight shrugged and popped the rest of the muffin into her mouth, carefully cleaning all around her teeth with her tongue and swallowing. "Okay, loons, I'm done. Little miss in-a-hurry over here..."

"Great!" Starlight leapt up, tugging Twilight out of her seat magically -- then froze as Mrs. Cake came back down the stairs.

"Oh, have I caught you leaving? Have a great day, dears," she smiled.

Twilight bowed, ignoring Starlight's face quickly turning blue. "We are satisfied and honored as always, o motherly one."

"No," Starlight hissed, "Out..!" She struggled to drag Twilight out the door with her magic as Mrs. Cake leaned back with a hoof to her chest.

"May your wide hips and glorious undercarriage forever swing and never sag," Twilight added, still bowing, her hooves grinding against the wood.

Starlight stopped dragging Twilight as soon as she heard the heavy slap of Mrs. Cake swooning onto her belly, her enormous tits spread to each side on the floor. Starlight roar-sighed, rearing up with both hooves on her forehead and her teeth clenched, and collapsed onto her back.

"Honey?" Mr. Cake called from the kitchen. "Are you okay?"

Thanks to this bizarre alternate Twilight's obsession with the things, Starlight was unusually aware that her teats were on full display and wobbling from the movement she'd just performed, and rolled over at once.

"O-oh," Twilight winced, wriggling her belly in sympathy pains. "D-did I say the blessing wrong..?"

"Ya knooooow I should proooobably have cut ya off before ya did that," Pinkie admitted with a blush, leaning next to Mrs. Cake in concern.

Starlight stomped back to her hooves and ripped Twilight out the door without another word.

Twilight wasn't sure what happened. She turned a corner and Starlight wasn't with her anymore. That was fine -- Ponyville was laid out the same as in her world, she could find her way back to the giant crystal castle. Right?

She waved to Vinyl and Octavia as they passed by, turning her head to stare after them as they passed. Huh, she thought. Octavia's ass is still huge, but her tits are even smaller than mine right now. Vinyl's not much, either. She pouted. How can these ponies protect themselves or do much of anything without Titty?!

How indeed? She frowned, thinking it over. They must have some kind of magic that... Her eyes widened in fear. ... isn't based on titty..? She squeezed her eyes shut and shook her head. That's impossible. She felt dirty even thinking about it. The Princess would be shocked I dared to think of such a thing. And even if that were true, I could never master such a power... But then what is this tittyless Twilight's magic..?

It didn't matter. Ponyville was safe - she wasn't in any danger here. The only reason she needed Starlight was to avoid getting lost, like she was now.

Her ears drooped as she realized the reason they got separated was because Starlight had refused to look at her. She hadn't said it outright, but Starlight was furious with her. She didn't understand. Surely a mare with such massive, hefty milkers commanded respect and admiration? What else could ponies structure their courtesy and honor system around?!

She turned back around and hesitated. She was standing too close to the houses and couldn't see the skyline to place the castle. Hmm, she fretted, The individual houses are slightly different, I'm lost without landmarks. I know the castle is west of the bakery, though. She turned and continued in that direction, glancing at the sky in the hopes of seeing the castle.

She stopped mid-step and blinked at a very conspicuous wooden box sitting in the middle of the road. What in the world? she pondered, leaning forward and tilting her head this way and that like a confused puppy.

"Twilight Sparkle!" came the sudden call after she had stared at it for a few seconds.

"W-what!" Twilight popped her head up and glanced all around in alarm. "Who's talking?!" And just after she'd realized she was powerless without titty, too. What were the odds!

"You have made a fatal misstep, and fallen into my trap!" As a strange mare's voice continued to speak, Twilight began to recognize her and relaxed. Oh not this bimbo, she thought, rolling her eyes. Well, let's get this over with...

Pssshh!!! Twilight began coughing on a smoke bomb and heard the sound of skedaddling hooves. "Ahahahaaack-cough-cough!" A powder blue mare rose above the mist, her starry cape and hat swirling in the night sky. "Behold, your nemesis! The daughter of the wind! The sister of the shadows! The Great... and Powerful... TrRrRrixie!!!"

This one hits the Rs too, huh? Twilight mentally sighed.

As the mist cleared, Twilight's eyes widened as she took her in, suddenly filled with horror. "Oh no," she began to shiver. No, that can't be. She took a step back, swallowing in panic. Trixie can't be stronger than this world's Twilight.

Trixie blinked at her in confusion. "Uh, are you okay..?" She cleared her throat. "Uh, Trixie means --" She threw out a hoof illustriously. "Yes! Shiver in terror, Twilight Sparkle! Your doom is at..." She pouted. "Hoof? Horn? Uh, your doom is really close!"

Even in her terror, Twilight found that strange. Why didn't she just say at boob like she always did?

"I... I cannot best you as I am!" Twilight objected, kneeling. "O Great and Powerful Trixie, I yield! Please allow me to pass!"

"Wha..." Trixie froze, blinking. "What?" After a few seconds, she lowered her raised hoof onto the box, tilting her head and scowling. "... Is this a trick?"

"Look between us! You clearly have the advantage..!" Twilight shuddered. I could get seriously hurt in this situation..! she panicked. There's no way I could possibly take her on!!

"You're making fun of me," Trixie scowled, stepping down off the box. "Can you at least try to take this seriously?!"

"T-Trixie," Twilight stammered, stumbling back and falling, "Y-y-you can't seriously expect me to fight such a well-endowed mare..!" She pointed a hoof at Trixie's bouncing undercarriage.

"Wh..!" Trixie's face lit up and she pulled her cloak around herself, stepping back. "What..!" she rasped in a ghostly wail.

"There you are!" Starlight came running, all out of breath. "Trixie, this isn't a good time -- whoa, are you okay? Did she hurt you?"

"N-no," Trixie stared dumbfounded and red-faced, shrunken under her hat and cape. "B-but..."

Starlight looked between the two, her eyes briefly glancing to about where Trixie's boobs would be, then her head jumped up and her eyes closed. She bit her lip. She dropped her head, nodded, and opened her eyes again. "Crossed daffodilling stars," Starlight sighed. "Twilight, come on, let's go, no need to fight, girls."

"Oh Starlight, save me," Twilight clung to her. "You didn't tell me Trixie's tits were still so huge! She'll destroy me! Heck, she'll destroy you too! Let's get out of here!"

"D-don't worry, we're friends," Starlight's face turned red. She glanced again at Trixie, who was basically just wild eyes over a red nose in a cloak and a hat, like Twilight was about to start monkey-howling and trying to bite her boobs off. "But yeah, she's, uh, a natural wonder, let's get you back home, Twilight! I am so sorry, Trixie."

"Trixie has received one compliment from Twilight Sparkle ever and does not feel proud at all," Trixie complained shakily.

"Try a dark bodysuit under the cloak," Starlight gave Trixie an apologetic smile and guided Twilight away in a hurry.
