Always Check Your Equipment

The sounds of mechanical churning and the buzzing of electricity were what woke Trixie from her slumber. Her vision was blurry and dim, even as she woke up, and her memory was foggy at best. The last thing she remembered, she was in Manehatten, still slightly bitter after being humiliated by Twilight Sparkle but deciding to take time away to "refocus" herself. This, to her, involved plenty of sleep, performing on the street of what was known as Busker Street, and wallowing in her own self-pity and cider while pretending not to be a grump. She tried to shake her head but found it stuck. Something was holding it up in place. In fact, her entire body was standing perfectly straight, a feat she was surprised she could pull off. However, that was pushed aside immediately as she noticed that she was completely topless. She yelped and tried to cover up her light blue breasts, but noticed that the rest of her body laid bare as well, her usual "flirty magician" attire completely absent and nowhere in her immediate sight.

"Oh good! You're awake!!"

She turned slightly at the voice as she focused, noticing a shape moving towards her. As her vision regained clarity, she noticed both the figure and her surroundings. She was in what looked like some kind of laboratory full of weird machines and gadgets, tables with beakers and all manner of things science. At least, that's what Trixie saw. She wasn't really sure what it all meant, considering that she wasn't the biggest mare when it came to "book smarts". The figure herself was a mare about her height, magenta coat and a green mane, wearing nothing but a lab coat that was buttoned down to show plenty of cleavage and barely covering her ass, revealing her spiral cutie mark. She had a smile on her face as she walked across a platform with a wrench, going to a podium and opening one of the sides to work on it, although from Trixie's angle, she couldn't make heads or tails of it.

"Don't mind me, I'm just fixing up this machine a bit! We'll have it- and you- up and running in no time!"

"Whaa... What is going on? The Great and Powerful Trixie demands to know where she is and why she's naked!"

"Hmmm?" She peeked up curiously from the panel. "Oh, you're in my lab! I'm Sleepy, Sleepy Spirals! All my patients just call me Doctor S, though."

"Doctor S...?" Trixie tilted her head as best as she could in confusion. "Wait, does this have to do with giving Trixie an exam?"

"What? No, silly! I'm not that kind of doctor!... Although, I did have that pharmacy... Does that count?"

"Well, why is Trixie here and why is she naked??"

"Well, I didn't want your new boobs and butt ripping up that cute outfit you had!!"

Trixie paused, staring at the doctor in bewilderment. "New... Boobs?"

"Yeah! I've got my handy little Brainscrubber here..." She patted the machine, letting an audible metal thunk echo out from it. "And it's going to take all those silly magic tricks and make them magic sex tricks!!"

"E-Excuse Trixie?!?" Trixie wanted to lean in, but her head was still held up. She finally turned her gaze upward, noticing the pink helmet holding her head in place. From what she could tell, it was connected to some long tube that was, in turn, connected to glass sphere and then a massive device similar to electric orbs you saw in the cheesy sci-fi movies (Not that the Great and Powerful Trixie would subject herself to those, especially not on weekends). It seemed to crackle dimly, so Trixie thought it smart to try and wriggle out of the helmet.

"Ah ah ah! Careful, if you move too much in that thing, it'll just go off right now and turn your brains into goo! You won't be much of anything but a giant tit fucksleeve at that point!"

She watched as Sleepy looked at the clothing, smiling a bit as she held up the cape. "I gotta say, this is quite the lovely cape!" She held it out just out of Trixie's grasp, causing her to lunge her hand out and grab at it, running her hand through it and yets failing to actually grab it, closing her fist. She covered her tits back up and sighed, putting her free hand on her hip. "So, you plan to drain Trixie's brain with this thing?"

"Mhm! Drain it and make it a proper bimbo brain! Nothin' but sex up there, ponies'll think your brain's in your pussy!"

"So... How did you get Trixie here in the first place...?"

"Oh, that was easy!" She pulled out a ray gun, giving it a twirl. "This little baby comes in all kinds of modes! Stun, Hypno, Bimbo, Buttslut~... Of course, the ray gun is just temporary. The Brainscrubber here does a muuuch better job!"

"And just why are you intending to turn Trixie into said bimbo?"

"Well, isn't it obvious?~" Sleepy lept up, causing her own double D's to bounce. "Cause bimbos are the best! Also, I was planning on using your magic stripper shows to make lots of money."

Trixie rolled her eyes with a smirk. She was starting to buy this less and less. "Bimbofy me? With this thing? There's no way the great intellect of Trixie's could be washed away by a mere machine." She smirked more, her hand covering her breasts shifting a bit.

"Oh?" Sleepy leaned over the podium with a coy little grin. "Is that a bet?"

Trixie waved the hand on her hips over to the podium. "By all means, try... Just know that Trixie will have you in that machine soon enough~"

"Oh, we'll see about that!" Sleepy hit a few buttons on the panel. The screen went through a few lines of random code before eventually bringing up a screen.

With a final grin, she pressed a finger on the panel, the machine whirling up and sparking to life. The lights flickered as it powered up more and more, Trixie looking up nervously as she tried to tug at it. "T-Trixie takes it back! Get it off, it's sucking at my head!" Still, her pleas came on deaf ears as the sounds of the Brainscrubber roared and Sleepy cackled in absolute glee, shoving a hand down to her pussy and rubbing it in anticipation.

And that was when all the light died in the facility, save for a few quick flickers. The machine suddenly went silent and Trixie, although shaken, still had her intelligence. "Oh, come on! I thought we properly fixed the fusebox!" Sleepy shouted as she pulled out a big flashlight, turning it on to reveal the area "Seriously, we need better fuses for this place... E-Excuse me a moment." She scampered off behind her to tend to the power, leaving Trixie there with an ever-loosening helmet. She tried her magic, but the helmet seemed to come with a built-in inhibitor, leaving her to carefully jimmy her way out. The machine seemed to have no reaction to it, thankfully, leaving her to escape with relative ease. Shaking herself free, she moved her mane aside, spotting Sleepy in the middle of repairs. She grinned as she looked at her hand...

Within a couple of minutes, the power came up to full brightness, the scientist sighing happily as she wiped her brow, walking back with the most oblivious expression. "Well, that takes care of that! Now, why don't we-Hey!"

She spotted Trixie leaning against the panel with her cape, smirking as she swished her tail. "Miss me?~" Sleepy reached into her coat, but before she could pull out her ray gun, Trixie threw down her trump card: A smoke pellet she always hid in her secret compartment. A cloud of azure smoke filled the air, completely obscuring the scientist's vision, who opted to fire blindly into the cloud and hope she hit her target. Of course, being lifted by some kind of force proved that this method, as always, wasn't a smart plan. She flew forwards and into the Brainscrubber, the helmet latching on rather easily as her lab coat was removed. "H-Hey!!" She yelped as she squirmed in place, remembering her countermeasures. "That's not fair!! You tricked me!"

Trixie simply shrugged with a smirk as she got behind the podium, watching it go through the same process again as it rebooted. "What can I say? I told you I'd have you in this device soon enough~"

Once the Brainscrubber properly rebooted itself, it started itself back to the beginning, asking if she wanted to continue. She reached a finger down...

"Boop!"

The machine roared to life once again, lights flickering as the electricity within sparked, powering up as it began to vacuum at Sleepy's head. Yelping in shock, she squirmed and reached out with a nervous giggle. "H-Hey now, Trixie! We can be reasonable! J-Just cancel the sequence now and I'll Uhhh... I-I can get you special devices to make people enthralled in your show! O-Oh, jeez, my braaaain...~" Her knees buckled as her eyes cocked upwards. "J-Just name your price, hehehe! Just get it off, my brain is getting SuuuUUuuuhhhh...~" With one slurp, Sleepy slumped forward a bit, drooling over her breasts as a massive amount of grey energy was pumped into the glass sphere above. Trixie watched in awe as it slowly molded itself, going from an off-grey to a more light pink, then a brighter, more obnoxious pink, before that energy was stuffed back down into Sleepy, the helmet soon releasing her from her binding with a Ding! Her tits and ass gradually expanded the more the pool of energy was put in and her dimwitted gaze became a ditzy, bubbly smile that seemed to stare into space. Her hands glided up to her chest, squeezing and rubbing it slowly with both hands as she let out a mix of a moan and a giggle.

"Hehehe~ Like, Sleepy's brain feels all better! Thanks sooo much, Trixie!"

Trixie smirked and moved past the podium. "That's The Great and Powerful Trixie to you~" She leaned back against the podium and held out her bare foot. "Now, be a good assistant, crawl over here and worship your Great and Powerful Mistress's feet~!"

Squealing in delight, Sleepy got onto all fours and chirped excitedly, "Like, totally Great and Powerful Mistress~" She carefully crawled over, swaying her butt from side to side in anticipation as she pressed her snout into the sole. The scientist-turned-bimbo then took her time carefully planting kiss after kiss on each foot and running her tongue along them, lewd moans and airy giggles coming from her as she gradually earned her permission up the magician's slender, beautiful legs. Trixie, meanwhile, rubbed her own tits in pleasure, the rush of dominance filling her up with more and more as she commanded her, eventually watching the bimbo mare bury her face in between her legs and lap away at Trixie's pussy. She cocked her head back and moaned, both aroused to no end and surprised at Sleepy's skillful technique. Trixie reached down and gripped her hair, grinding against her face as she lapped away, her moans echoing throughout the facility as she was repeatedly tongue fucked by Sleepy. She bit her lip to try and hold it back, but as soon as she felt her sweet spot getting hit, she threw her head back, crying out in pleasure as she sprayed her juices all over the former scientist's face.

"Haaah... Haaah... That was... Amazing..." She panted quietly, wiping the sweat from her forehead as she leaned back against the podium. She looked down at Sleepy, who was apparently edging the whole time, looking as if she were going to collapse. Trixie smirked, reaching her foot down and rubbing the mare's pussy slowly. "Now... Who do you obey, Slutty Spirals?~"

"Ahhhh~!" Slutty, as she was now dubbed, writhed on the floor as she felt her mistress rub her foot against her most sensitive area, drooling with a big, goofy grin on her face. "Like, Slutty obeys The Great and Powerful Trixie~!"

"Mmmhmhmhmmm... And you'll do whatever The Great and Powerful commands, correct?"

"Oooooo, like, yes yes yes~ Obeying The Hot and Sexy Trixie is totes what I live fooor~"

Trixie's grin grew wider as she looked around at the devices and contraptions. "Say, you wouldn't happen to still now how to build your fancy gadgets would you?"

"Like, nope! Why would I wanna do a thing like that?~ I'd much rather fuck and serve The Cute and Busty Trixie and let my robots do the making!" She reached into her lab coat and poked a remote she found in one of the pockets, causing several robotic ponies to march into rows and salute. Trixie rubbed her hands in anticipation. "Excellent..." She muttered, working her plan together.

Twilight stretched as she wandered through the streets of Ponyville. Things seemed to be settling down for a change. Everypony was getting along, there weren't any big villains she had to hunt down and even the minor things were solved in a day. It was nice and peaceful.

...

In fact... It seemed too peaceful. The streets were looking a bit vacant, no one was manning their shops and stands and even her friends seemed to be missing from their usual spots. "Where is everyone?" She wondered to herself as she wandered. That's when she heard the sound of cheery, bombastic music that seemed to lure her towards out of curiosity. She listened carefully for it, wondering if this was another one of Pinkie's surprise parties. However, the crowd in the distance was telling her that this was far from the case. A pit dropped in her stomach as she ran towards the crowd, and that's when she spotted that everypony was naked. Not only that, they were openly masturbating with big, drooly smiles on their faces. She gasped in shock as she tried to wave her hand in Caramel and Lily's faces as well as a few of the others, but this didn't stop them. "Just who is responsible for Thiiiiiiuuuuuhhhhhh..." She looked up in the direction of the others, and that was when she was met with large screens with light blue spirals, with transparent images to a familiar sparkling wand cutie mark and an even more familiar mare, jiggling her bare chest and ass shamelessly for them to see.

Trixie...

Twilight blushed as her mind drifted the more she stared up at the screens, feeling her panties dampening while her hand instinctively went for her crotch. She couldn't even fight it, rubbing herself through her clothes as thoughts of Trixie's ~~perfect~~ body moving and presenting to her, trying ~~and failing~~ to fight it. Her body heated up more and more, her panting getting louder as she gripped at her own clothing. Unable to cope with her burning estrus, she tore the clothes right off her body, spreading her legs wide so she could finger herself better. A ditzy voice came onto the intercom.

"Like, okay everypony! Please stroke yourselves for, like, the one... The only... The Great and Powerful Trixie!!"

The entire audience burst into a loud cheer, never taking their hands off their crotches and just masturbating harder as their siren came onto the stage. Trixie definitely had larger breasts and a larger butt than before, but baring that, her outfit had changed. While it was always a bit risque, here, there was much less material with way more cleavage exposed. At that point, it was hard not to make the comparison between it and a playstallion bunny outfit. She bowed low, giving them all a good look down her immaculate rack and prompting louder cheers and moans.

"Mares and Gentlestallions! It's so nice to see you again, especially now that you all see how great I am!!" They cheered, Trixie basking in the praise. "I promise you that after today's performance, nothing will be the same, and you will all love and adore me!!" With that, she began to perform her usual array of tricks, all with a slightly lewd spin on it and with the aid of her new busty bimbo of an assistant. In truth, not much had changed, but the crowd was so enthralled, they could do nothing but cheer and praise her for her every action. Even Twilight was amazed by her relatively subpar magic tricks. Once the end came, however, Trixie pointed to the crowd with a massive grin. "For my grand finale, I will make the intelligence of the smartest mare in Ponyville disappear~"

The crowd ooo'd in amazement, one of the bright, swirly spotlights pointing down at the one Twilight Sparkle. "Ahhh, there she is~ Come up here! And don't stop rubbing yourself..."

"Ahhhhh... Yes, Trixie, of course! Anything you saaay!" Twilight moaned as she lumbered through the crowd, fingers still within her twat. She clambered onto the stage, flapping her wings in excitement as Slutty brought down a large box with the Brainscrubber attached to it with the press of a button. Trixie then turned to the crowd, tapping the box which opened it, revealing the empty interior (save for the helmet inside). The two shoved Twilight in, strapping the helmet on and shutting the box. She waved her arms around the box, sneakily pressing the device on and bringing the brain-draining device to life. Twilight's cries of surprise and ecstasy could be heard from inside as it quickly gathered up all her knowledge and scrubbing it way, stuffing it all within her tits and ass while the crowd stared in anticipation. The door swung open, and Twilight popped out, stumbling drunkenly and giggling with a dim expression. Her body matched Sleepy's and might have actually gotten a bit larger, and she simply giggled and drooled.

"Like, wow! You made my head feel all quiet and happy and stuff! You're totes better at magic than I thought, Trixie!"

"Why thank you~ But if Trixie's better than magic, wouldn't that mean Trixie should be the Princess here?"

"Like, ummm..." Twilight scrunched up a bit, unsure of how to think of any way around that logic, given she was now as dense as a log. "I guess you're totes right!! Wow, you're suuuper smart! You should definitely be in charge!"

"Why thank you! Why don't we have a little ceremony in my honor~? But first..." She pressed a button on her remote, her updated stage wagon producing a table with outfits matching her own. "Everyone, come and buy your new outfits! You all love and adore Trixie? You want to be like Trixie~? Buy The Great and Powerful Trixie's lovely outfit for just 60 bits apiece!" The crowd clambered towards the table, grabbing their money and handing it in droves as they tried to get their own leotard, fishnets, high heels, capes, and hats...

Everypony stood at town hall, blank, happy expressions all their face. Everyone, even the stallions, were wearing matching sexy magician outfits to match the other, and all to match The Great and Powerful Trixie herself. Mayor Mare and Twilight stood at the town hall's podium, smiling just like the rest (although Twilight's was definitely dumber).

"Mares and gentlestallions," the mayor spoke up. "Today is a wonderful occasion, as we are here to announce the new leader of Ponyville! Our Great and Powerful Leader, Princess Trixie!"

The crowd cheered, clapped and stroked, all to the chorus of "All hail Princess Trixie!" as the princess herself walked onto the podium and waved to everyone. "Hehe, yup!" Twilight spoke up. "And like, Mayor Mare an' me are gonna quit being mayor and princess so we can be her personal servants, sooo... That means you gotta do what she says!"

"Indeed... And the first order I decree... Ponyville will be renamed to Trixieville!" The crowd cheered and rubbed themselves harder, happy to be part of this new town with the best princess ever. Trixie smiled as she pulled her assistant close with one hand and her fallen rival with the other, her hand on both their asses as she groped them slowly. She had big plans for the town, and with Sleepy's robot servants, it would all be too easy.
