Celestia’s shape jiggled as she stood in place, her mouth covered in ‘protein shake’. She felt totally exhausted, her tits and ass were huge now, and she just wanted out of these damned cursed heels that Eris had stuck to her feet. She looked up at the female draconequus with a groan, emptied fleshlight in hand and trying her best to keep her tits from knocking her face first. “Okay, we did it… Are we done, Eris…?”

“Not yet~! We still need the big finale!”

“Th-The… Big finale…?” Celestia gulped nervously. “A-And what would that b-EEEEEE!!”

Suddenly, Eris gripped onto Celestia’s ear and pushed her head in, stretching it cartoonishly as she pushed deeper and deeper in. Celestia squirted involuntarily at such a strange sensation, her eyes derped and her tongue hanging out as more and more of Eris fit in her head. She didn’t know how she could fit in, but she was more worried about what Eris’s plan was.

Soon, Eris’s whole body fit inside Celestia’s head, and with a little wiggle, shrunk down to the size of a speck, perhaps one obsessed with a secret burger recipe. “And much like that speck, I’ve got the perfect tool to control this princess~” Eris thought, reaching behind her body and producing from nowhere a large remote control with buttons and levers in it. She plugged it into the princess’s brain, producing an audible squish and a loud “BUHEEE!” from Celestia.

“E-Eris, what are you doing in there??” Celestia shouted before suddenly finding her body standing at attention. Then, her arms moved out as she began to zombie walk forward. “H-Hey!!! What gives!!”

“Like I said, Celly! It’s all for the grand finale!” Eris snickered inside Celestia’s head. “A nice stroll around the castle before all of your loyal subjects~”

Celestia’s eyes widened. During the humiliation, she was counting on the fact that nopony was around to see her get humiliated to carry her through all this, knowing she could play it off. With the threat of being spotted on the line, she finally caved and started to pathetically beg. “Okay, Eris! Jokes over! Take these heels off now!”

Eris giggled and shook a finger back and forth in Celestia’s face. “Not yet, Celly! You’re going to give the guards a show first!”

Celestia’s voice sounded more frantic as she pleaded. “I’m sorry I ate your cake! I’ll get you a new one! H-Heck, I’ll eat you out every night for a year!”

“No can do… That cake’s gone straight to your butt, and I’m going to make sure you work it all off tonight!” Eris cackled as she saw Celestia march to her fate, satisfied with her revenge. Just seconds into it, however, she held out a hand. “WAAAAAAAAAIT!!!”

Celestia’s body froze mid-march, a wave of relief flooding her body. Finally, Eris had come to her senses! Maybe she’d have to do some other compromising things, but it was better than letting everypony see her in this state.

Eris crossed her arms as she looked down at Celestia’s brain. “Do you know why I stopped you, ma’am?”

“Ummm…” Celestia’s eyes looked around nervously. “Because you’ve had a change of heart and decided it wasn’t worth humiliating me over a cake?”

“No, you dummy!!” Eris reprimanded her, waving a finger in her face before pointing at the ground just before her. “Look! You almost hit that puddle of your own juices! You or somepony else could’ve gotten into a serious accident! Obviously, that needs to be cleaned.”

Celestia awkwardly gazed down, and sure enough, a large amount of the floor was covered in her feminine fluids spilled out on the floor. Her mind had been so foggy, she didn’t even realize how much she’d cum until right at this moment. She’d utter a nervous chuckle, looking up at Eris. Maybe I could stall her with menial tasks…? “I-I suppose you’re correct. Shall I clean-?”

“Well of course you’re cleaning it! And with the best tool known to man!” Eris snickered and snapped her fingers, Celestia quickly becoming subsumed in the flash.

As she quickly recovered, Tia wasn’t fully sure what had happened. She didn’t see a mop, and her body seemed unchanged… That was until she opened her mouth, and suddenly her newly elongated tongue came rolling out.

“B-Bleeeehphgh!” She tried to speak, only for her body to get down on all fours.

“Ehehehe! Start cleaning, Tongue-Twat~” Eris mockingly said as she watched Celestia’s newly changed appendage slowly run up and down the bathhouse tiles. Seeing the princess closing her eyes in an attempt to avoid acknowledging what she was doing, the chaos goddess gave a coy smirk and snapped her fingers. With a quick point to the princess’s lips, Celestia’s eyelids shot open, watching as her new big tongue slowly slurped and licked every inch of the puddle-covered tiles until they were spotless.

Once done, Eris cackled in delight. “Wow, Celly~ Didn’t take you for such a thorough floor cleaner! This floor is so spotless, I could eat off of it! In fact…” With a snap of her fingers, she produced a whole feast all over the floor and had Celestia eat from it with her large tongue. After just a few bites, however, she shrugged and tossed her utensils on the floor. “Eh, I’m not hungry. Celly, clean this up.”

“Bbblg?? Pppbbloo bbllln pptt!!” Celestia tried to indignantly say, only to have her tongue in the way.

“What? A little tongue-tied~? Here!” With a big grin, Eris made Celestia snatch her own tongue and scoop up the feast with one lick, then with a quick stretch forward, the tongue shot back and flew into the mare’s mouth with the sound of coughs and sputters. “See, was that so hard?~”

“Y-You… If only I could get my hands on you… I-I’d-” Celestia coughed out as she tried to get her hands on her own breath, but Eris simply waved her off in dismissal.

“Yes, yes. Big threats from the big, scary mare. Look, we’re way behind schedule!” She whipped out a big clock and pointed to it before swatting Celly on the ass. “You need to get moving, missy! Or you’ll be late for your show!”

“YIPE!! B-But wait-MMM!!” Celestia’s pleas were stopped as the corners of her mouth were stretched back into a big smile, ruby red lips on display as she stood up straight then began strutting with a big sway in her hips. As she moved her arms to try and move her mouth, they shot to her sides while her hands moved to a flat position, giving the impression of a slutty, show-offy mare definitely not held against her will by a spiteful draconequus. Now, all she could do was watch as she strutted out of the bathhouse in view of the two guards before stopping in front of them. Eris pressed a button, producing a microphone which caused Celestia to speak whatever Eris said.

“Heya boooys~” Celestia spoke through her forced smile. “Like, wanna see my sexy dance moves?~”

She slowly stuck her ass out, moving her big ass up and down for the guards who watched in complete shock. Neither knew if this was a test or a prank, and were afraid to say otherwise. They just watched as Celestia gradually squatted down low and wobbled her flanks one cheek at a time. The rhythm was so fast, the clapping audible and enough to make the stone-faced guard red in the face. “Like, you better jerk off to me lots and lots! That’s a princess’s order!”

Just saying and doing all this was enough to make the princess’s cheeks bright red, but she was barely able to control herself out of a Eris then had Celestia rise seductively, slapping her own ass and winking at them. “Like, hope to see ya studs soon~” She said coyly before putting her hands back on her hips and strutting out towards the castle, all with Eris’s control.

“Hey…” One guard spoke up as he watched his princess’s bare ass wobbling from side to side. “Was that-?”

“Yup.”

“Huh… Should we… Do something?”

“I’m telling you what I’m gonna do,” the second guard mumbled as he walked into the bathhouse. “Obey the princess’s orders and rub one out. Watch my spot.”

~~~

Inside the castle, a maid quietly hummed as she dusted off a priceless vase, smiling at its spotlessness before turning to move on to the paintings. Just as she did, she felt something smack into her face. It was big, jiggly, and soft, but moved with enough force to make the poor mare stumble slightly.

“Hey, watch where you’re-!”

She immediately cut off as she saw just who it was that knocked into her. Princess Celestia, dressed in nothing but a pair of shiny heels and a smile as she sauntered down the hall like a sultry mare of the night. The maid’s eyes widened, rubbing them as she looked utterly confused.

“P-Princess?” She called out, feeling like her eyes, or even her mind, were deceiving her. “Princess Celestia! Is that you?”

Sure enough, Celestia looked back and gave an alluring wave and a shake of her widened hips to confirm that it was her, smile never fading. Of course, none could notice that the smile was strained and being held up by magic, the same coming from those shining heels. However, that was far from relevant at this point as Celestia paused and slowly squatted down.

‘W-What should I do??’ The maid thought in a slight panic, her eyes locked onto those clapping cheeks. ‘I-I have to warn somepony! The guards, Princess Luna, any-!’

CLAP CLAP CLAP CLAP!

DING!

“Booooty…~”

Suddenly, Celestia began to bounce her ass up and down, creating ripples in her ass that blended with the magic and captivated the helpless maid. As Celestia continued to clap her cheeks with her hands down near the floor, she could hear Eris cackling in her mind.

‘Ohhh, this is priceless…!’ she squealed, audibly chomping on popcorn in the Princess’s mind. ‘I don’t know how it can get any better…!’

‘D-Don’t think… You’ve won, Eris…!’ Celestia angrily through her wide smile. ‘Y-You made a fatal mistake in your hubris…! My hands are just within shoe grabbing range!’

‘Wait, what?’ Eris watched as Celestia’s hands managed to grab at the heels. ‘Wait, don’t! C’mon, Celly! I’ll put you back, just don’t try and take ‘em off!’

‘Too late! Now take this!’ Celestia, confident beyond measure, tried to pull off the heels and used the limited mobility she had to flop out of them.

tug.

Nothing. She blinked, and tried harder.

tug tug.

Still nothing.

No matter how hard she tried, the alicorn couldn’t escape, and now, she was being punished by hearing the cackling giggles of Eris. ‘You idiot! You totally fell for it! Ohhhh, this got soooo much better~!’

Celestia’s cheeks (the ones on her face) turned a bright red from blushing in embarrassment, finally stopping her futile escape attempt. ‘W-Whatever… Hope you’re happy…’

‘Oh, far from it! My Celly being a naughty filly and trying to stop our game early? Very, very naughty! I think we need a bit of a PENALTY GAME~!’

SNAP!

BWOOOOMMP!

Suddenly, Celestia’s ass expanded to double its size, bouncing with much greater ease and making much louder clapping noises as a result. Her tempo picked up, making the loud claps more frequent, and, to add insult to injury, Celly’s mouth opened wide… And shouted.

“Like, heya! Come and watch Celly Sunbuns bounce this big fat royal booty for everypony! Watch it jiggle and wobble! You’d, like, swear my brain was in my ass~!”

‘N-No, my subjects! Don’t come any closer!’ She thought, but it was futile. Soon, residents of the castle that caught an earful were slowly coming out. They looked confused, worried, and the guards were on high alert, keeping a sharp eye in case anyone dared try and invade on their watch. However, once they got to the hall, all they caught was an eyeful of their princess shamelessly shaking her ass for them.

“That’s it, studs and sluts! Keep, like, comin’ and get a load of this~!” Celestia’s upper half pushed itself on the floor while keeping her legs standing and spread, making her ass the most visible thing as she began to shake harder. The claps moved in a rhythm, and the ponies who dared look followed the cheek’s rhythm back and forth, back and forth…

CLAP CLAP CLAP CLAP CLAP!

Their eyes widened, but soon drooped as they began to stare at that alluring wobblemeat. Soldiers dropping weapons and cleaners dropped their tools as all of them stayed glued on the greatest thing that they’d ever seen.

“There we go, slut! Look at your audience! You’re a star!’ Eris teased.

‘I’m a laughing stock!’ Celestia retorted back as she shoved her ass against a guard’s face and slapped his face with her cheeks.

“Oh, please. They’re not gonna remember this. Probably. Anyways, you know what this calls for?”

‘A trip to my room to hide…?’

“No, idiot! A song!”

‘Wait, wha-?’

Suddenly, Celestia’s ass smashed against the wall, revealing from it a boombox with spiral patterns against the speakers. Without missing a beat, she knocked the device in the air with an upwards butt bump before letting it land on her ass like a shelf. With a simple press, the device began to let out a funky beat which Tia’s ass was unable to resist. Her twerking moved to the fast, thumping beats, and with it, the eyes of the servants began to swirl. Their mouths hung open, and they were left totally entranced.

“Bam! Now that’s a group of subjugated slackers I see~!” Eris clapped in delight. “Now, why don’t we go on and look for more~?”

‘No no, you can’t make-!’

“Like, right away, boss~!” Celly giggled as she marched on, her inner voice screaming until it was briefly silenced with a bonk that was only heard in the mind of the doomed princess.

~

Celestia would repeat this process every so often, gaining more and more hypnotized followers as she stopped to make impromptu ‘performances’ for anyone unaffected, and it was always effective. No one was able to resist, and soon, she had a full force following her.

“And, PAUSE!”

Celestia’s body came to a stop at Eris’s command, and her arms moved in order to turn off the boombox. Her whole body was drenched in sweat, and despite never breaking her smile, she definitely seemed a bit worn out.

‘Th-Thank… Goodness…!’ Celestia panted in her mind, her ass still jiggling on its own.

Eris snickered at the state Celestia was in. “Awww, is Celly Sun-Buns all worn out?”

‘Sh-Shut up…’

“You know, you really should be thanking me. This is probably the best workout you’ve gotten in years-”

‘J-Just give me some water, you whorse!!’ Celestia finally snapped back in anger, only to realize her mistake half a second later. ‘I-I’m sorry, Eris. I’m just… S-So worn out-”

“Well you don’t have to be rude about it!” Eris huffed loudly as she snapped her fingers. “If you wanted hydration, I know JUST the way we could fix that!”

‘... H-How…?’ Her head slowly drifted towards the door to her right, and her eyes, even under Eris’s control, widened. ‘N-No… Not there! Not her!’

“Too late! Should’ve been nice!”

‘Eris please-!’

“Get to struttin’, Sunbuns!”

Celestia felt an invisible hand smack her ass, causing her body to strut in and wave. “Hiiii, Luna!”

Luna, originally lost in thought with some texts she was reading, nearly leaped up and turned back to face what sounded like her sister. “For Faustia’s sake, sister! Must you-... You…” Her eyes looked up and down at the completely nude visage of Celestia, completely caught off guard as she shook her head and cleared her throat while her cheeks felt warm. “S-Sister… Might I ask why you are parading around in nothing but… W-Well, a pair of heels for a mare of the night.”

“Well, I was in the bathhouse, got bored, wanted to see you!” ‘Celestia’ said through the puppeteering of Eris, sauntering over to Luna’s desk and leaning forward while pushing her ass out.

“Y-Yes, well… Surely, you could’ve had the patience to put on clothes or at least a towel before meeting me…” Luna tried to look away as she blushed, but for some reason, she kept stealing glances at that enormous posterior.

“Well, I did have one, but it fell off and I didn’t wanna pick it up! My tits are sooo big, I’d probably be stuck forever!” As the princess of the sun giggled, she began to shake her ass from side to side in a playful manner. Luna’s eyes widened as she saw the rhythmic jiggling of flesh, her face nearly going bright pink. Now, it was taking all her might to not stare at that bouncing bubble butt, and even then, she had at least one eye trained on it.

“I-I see…” Luna mumbled, trying to focus even as her thoughts began to get filled with thoughts of butts. “A-Are you positive nothing… H-Happened…?”

“Happened? Like what?” This time, Eris had Celestia ‘stretch’ her ass back, shoving it out closer towards Luna. Her shaking began to get more intensive, returning to an outright twerk and the sheer sight of rippling buttcheeks and rhythmic clapping made thinking a near impossibility.

“L-Like, uhhh…” Luna blinked, a bit of drool escaping her mouth. “Uhhh… Buh…”

“Buh? Like, Butt? Ass? Booty? Cabooze? Dump truck~?” ‘Celestia’ snickered as she looked back at Luna, the poor Princess of the Night becoming so enthralled in her own ‘sister’s’ performance. She was hunched forward, eyes becoming filled with colorful swirls as she was totally entranced. Ignoring Celestia’s feeble attempts at regaining control, Eris made Celestia slap her own ass.

“Hmmm? Loony-Luna, you seem, like, totes distracted~ What’s on your mind~?”

Luna could only respond in a dull monotone, staring forward as she mumbled. “Butt… Ass… Booty… Caboose…”

“Awww, my sissy’s totally butt-notized~ Guess she won’t mind if I…” Celestia sauntered over to the floor, heels clacking on the tile floor has her hips bounced from side to side. She cupped the chin of her sister and slowly lifted her head up, looking down at ‘her’ sister with a smirk.

“Golly goodness… I could do SO many fun things here…”

‘R-Really, Eris. You don’t need to do this! I’ll let you give me a big cock! I’ll let you have me run around and act like a chicken! Let’s get out of here and-!’

“Now kiss!”

‘M-Mmmm!!’

Before Celestia could plead any further, she was suddenly embracing her sister in a deep, passionate kiss. She wrapped her arms around her waist and rubbed her body up against Luna’s without an ounce of shame. Luna’s body seemed to move on its own, moving up around Celestia’s neck as she returned the kiss. Eris cackled in perverted glee as she practically held them in place, making their tongues rub against one another vigorously.

“Mwah, mwah~ ‘Ohhh, Celly Sunbuns! You’re soooo sexy!’” Eris teased, badly imitating the voices of the sisters. “‘Oh, Loony-Luna! Your boobs are the finest in the land! But they could be BETTER!’”

Celestia was about to lash out until she noticed a sensation pushing against her chest. Barely able to open up one eye, she looked down to see Luna’s chest start to expand. Her breasts, lithe and modest, pushed out more and more against their fabric prisons, straining against the bra until an audible SNAP was heard and her tits bounced a bit. Even then, they didn’t stop expanding, pushing against Celestia’s chest and putting more and more stress against the elegant royal dress until-

RIIIIIIIIIIIIIIIP!

The enormous tits caused a tear right down the middle, exposing Luna’s enormous breasts even more and making an audible sloshing sound as if filled with liquid. In fact, when Celestia looked past the kissing, she saw that Luna’s nipples were in fact leaking…

“Mmmm… Sis’s, like… Parched…” Celestia mumbled as she broke the kiss, panting as she slowly moved down and kissed down her sister’s dark blue chest. She ran her tongue along those enormous peaks, her ears picking up the silky smooth sound of Luna’s moans which made her own nethers warm with Eris’s aid. Her lips curled around one of the leaking nipples as she began to suckle.

“M-Mmm??” Even controlled, Celestia let out a squeak of surprise. As she suckled at the teat of her sister, she found something that wasn’t milk but rather… Something watery and sweet, like water, but if it had a fruity flavor. Almost… Blue flavored. Shifting her eyes to the other nipple with all her might, she’d noticed that, indeed, what was pouring out wasn’t white but rather a clear blue liquid.

“Do ya like it?” Eris chimed in. “It’s my newest creation, Luna-ade! Guaranteed to rehydrate and reinvigorate in one big gulp!”

‘You think you can use us like this?? I promise you, Eris, I’ll make sure you- Oh…’ The Celestia in her mind was surprised as she noticed her exhaustion and dehydration had begun to fade. ‘Well, that’s… Surprising.’

“See?? You were SO worried about this for NO reason!”

‘Eris, I am suckling on my sister’s tits which now produce some strange drink that is causing me to become wetter than pegasus racing through a rainstorm. I have ample reason to be worried.’

“Well, I know JUST how you can relax!”

Eris piloted Celestia to grab hold of Luna, holding her up over her head before chucking her onto the bed. As her younger sister ragdolled and landed with spread legs, Celestia leaped on top of her and began to kiss and lick her way straight down her flat tummy and below. Once she reached the crotch, she nestled herself into the fine crop of trimmed navy blue hair that welcomed her to that pristine pussy. Nestling her snout against those folds, she unfurled her tongue and began to lick away.

“Mmmm… Feel good… Butts…” Luna mumbled in her sleep, squirming weakly on the bed as she felt her sister’s tongue work her nethers like an expert. ‘Celestia’ swished her tongue about, almost recklessly as if she were trying to make Luna cum quickly. In truth, Eris was plotting a devious plot, savoring the mix of moans and groans of both pleasure and despair from the sisters.

All the while, she was moving Celestia around like her toy, moving the mare’s hand to Luna’s now moist pussy and sliding a few fingers inside. The insertion alone caused Luna to cry out in bliss, but the fast back-and-forth sliding of her fingers added to it and made her grip the sheets. Of course, all that Luna could see right now, all that occupied her mind, was butts. Big ones. Big, bouncy, jiggly ones in her face, for her to bury her face in and be smothered. An ass to eat out and be lost deep between the two round cheeks forever.

And soon, she’d get exactly that wish, as Celestia’s body shifted around on top of while never stopping her feast of royal snatch. As she flipped on top of Luna, the princess of the night would suddenly find herself staring up at the most perfect ass in all of Equestria. An ass that she couldn’t help but worship. An ass that she eagerly dove in and began to eat out as hard as Celestia was eating out her twat.

“M-Mmmmm~” Celestia’s eyes rolled up as she felt Luna’s tongue across her pussy, her tongue working that virgin snatch even harder. Her hips bounced up and down, slamming her ass against her sister’s face. For what felt like hours, they’d eat away at each other, and when Eris snapped her fingers, they were suddenly scissoring each other. They mashed their pussies together, rubbing back and forth like their minds could only think about sex. She could still taste the juices that spilled out of her sister on her tongue, but neither of them seemed like she never fully came. It was as if the two were locked forever on the edge of orgasm.

‘E-Eris… Please…’

“Hmmm? Please what?” Eris spoke in that tone of false ignorance, and despite the fact that she could hear the chaos goddess smiling, Celestia’s pride was crumbled under the weight of her need to cum.

‘P-Please… G-Give it… L-Let me…’

“C’mon, Celly. Use words. I can’t give anything to you if I don’t know what you-”

‘Cum! I need to cuuuum! I’ll be good, just let me spray my nasty juices!’

“Awww, why didn’t you say so! But, if you cum, you’ll be sharing it with Luna, and if she feels both orgasms at once, she might get all loopy~”

‘I don’t caaaare! Just let me-!’

SNAP!

“Ohhhhhhhhhhh~!!!”

Suddenly, the sisters were hit with the greatest orgasm of their lives, reverberating to their very souls as they squirted all over the place. Celestia had never cum so much in her life, and had she any awareness left, she swore she could feel her mind pop like a bubble. Even the part of her mind that was her own had fallen further away, screaming in pure ecstasy.

But if she was having such a good time, then Luna was falling deep into pure perverted nirvana. Her swirly eyes spun faster and faster as the twerking asses in her vision bounced faster and faster. She felt every inch of bliss from Celestia’s and her own orgasm, forming a stream of drool on her tits as her body seemed lost in a spiral of perversion and colors. Her body seemed totally weightless, floating about in her melting mind. She fell faster and faster, a huge, lustful smile on her face as she saw the infinity of lewd, seeing all that she desired…

But in reality, she’d passed out from the pleasure, snoring peacefully as she lay in a puddle of her own fluids and giving the occasional twitch. Celestia huffed as she lied by her sister and tried to process everything that happened. However, before she could even do that, she heard an all too familiar sound.

SNAP!

FLASH!

Suddenly, from between her sister’s spread legs, an enormous blue cock and balls sprouted from nowhere and stayed erect in the air. It twitched at the feeling of the air, sensitive yet strong. It was practically begging to be sucked on, and it didn’t help that Eris had the sight of such a beat causing Celestia to drool. Before she could even say anything, the Lady of Chaos had Celestia crawling over and wrapping her lips around that rod.

“G-Gck…!” She groaned as she felt it penetrate her mouth, slowly bouncing on the tip. She could feel herself getting lower and lower as her slobber dripped down, lubricating the cock and somehow letting it slide down her throat. She could smell how Eris had the cock produce this… Scent about it, a smell unbecoming of a princess, but something that made Celestia’s already moist and sensitive nethers cry out for more. A hand slowly moved down as she bounced further and further.

However, no matter how hard she tried, she never got all the way down. Time ticked on, and she bounced further and further down. Eris made Celestia grab and fondle her sleeping sister’s balls while her tongue lolled around and moved deeper and deeper down. She thought she’d only be bouncing for a few minutes, then those minutes became melded into a couple of hours. Sweat poured down on her brow as she gagged and took Luna all the way down to her base, taking in her sister’s scent as her own eyes rolled up.

SPLURT!

Suddenly, she was met with the rush of thick seed spilled out. She herself squirted a bit, her legs trembling as she sucked the cum out of Luna’s sack. The feeling was so blissful, and she couldn’t tell if it was Eris’s doing or her own perverted desires. Once Luna stopped, she pulled off, watching as Luna’s limp cock flopped to the side. However, she’d only get a moment to breathe before she felt an invisible hand slap her ass and cause her to stand up.

“Alright! Break time’s over! Time to get back to strutting!”

‘W-Wait, give me a break…! That was so much, I need to-!’

SMACK!

‘YEE-OUCH!!’

“Right away boss! Back to my strutties!” ‘Celestia’ saluted with a smile, quickly moving back to her rhythmic strut out of the room and down the hall, where her butt-notized subjects were waiting with swirly eyes, hard cocks, and moist pussies for her. None of them dared move or even try anything until they bore witness to the glorious sun-butt. From there, the gathering of brainwashed subjects held their arms out and zombie-walked behind Celestia as she strutted down the hall, moving to find more ‘playmates’ while her mind continued its helpless resistance.

~~~

“Alright, stallions! Let’s see some hustle! Don’t stop until I say so!”

The current commander of the Royal Guard shouted as he watched through the training, carefully inspecting every soldier as they trained. Every move, every spell, all of it to protect the Royal Sisters and Equestria as a whole. If they did not, if they relied only on the Elements, they had no reason to be called the Royal Guard! And his pride would not allow for that, not for a second. Of course, these soldiers definitely needed some more intense training, given how a bunch of them were completely distracted and looking away from him.

“Soldiers! What did I say about stopping?? What in Equestria is so important that you-??”

“Like, heya, Cum-mander~”

The commander’s eyes widened as he saw Princess Celestia, and almost by instinct saluted her before he really got a look at her. When he did, he was totally in bewilderment. She posed provocatively, giving the sultry gaze of a lover as she grabbed hold of her own breasts and bounced them up and down. To top it all off, she didn’t wear anything but a pair of shiny heels, seemingly not phased by it in the least!

“P-Princess! What’s gotten hold of you?? Put some clothes on!!”

“Mmmm… Nah.” Celestia giggled as she tweaked her own nipples, moaning. “In fact, I declare that all clothes be, like, gone and stuff, except for my shiny heels!”

The commander’s eyes widened as the crowd behind Celestia obeyed and slowly began to strip down. Something about this situation was wrong, darting his eyes to see if a potential culprit was at hand. “Your Majesty, you can’t declare something so… Depraved!”

“Oh? Why not? I’m, like, in charge and stuff!”

“But princess-!”

“Butt princess? That’s a good idea!” Celestia giggled and turned around, revealing her enlarged ass to the Royal Guard. She pointed to one of the enslaved crowd that held the boombox and snapped her fingers. “Hit it!”

With the push of a button, the music became on, filling the training grounds with the sounds of the brain-blasting beats. Celestia’s eyes crossed as she felt the wubs of the music thump against her brain while her ass immediately got to work following the music. She bounced her ass about to the rhythm, her tongue hanging out of the side of her mouth with the stupidest smile on her face.

The commander stumbled back, in complete shock at how perverse and shameless his princess was acting. Something was wrong, this had to be a trick! An evil spell! And yet… Why was it getting harder to look away…?

Using what willpower he could muster, he darted his eyes away with a growl. “L-Look away, soldiers! Don’t be fooled! This isn’t our princess!”

“Awww, like, so mean!” Celestia pouted, rocking her ass in circles and slapping it. “You act like I’m, like, some kinda big meanie mare! I’m fun! A fun princess! And fun means getting naked and horny when I say so!”

“N-No! I won’t listen!” The commander stubbornly covered his eyes and shut his eyes tight, trying to block out the princess’s seductive words and the clapping of her rump. Of course, while he was trying to shut things off and try to escape, the other soldiers were way less hesitant to look at the pristine white ass of their ruler. Their eyes stayed locked as ripples pulled their consciousness, their ability to fight back, their inhibitions deeper in the crack of her ass and leaving them squirming as their erections slowly pushed against their armor. Their eyes gradually took on a duller and duller appearance before slowly taking a familiar, colorful swirl. Their mouths slowly hung open and drool dripped down onto the ground as they fell into deeper and deeper levels of butt-nosis. Their bodies leaned in, as if trying to get deeper and deeper into that ass until-

SNAP!

With the sound of fingers snapping in their minds, they zipped to attention, blank expressions on their face while their eyes filled with colorful swirls. They were totally under her command now, and ‘Celestia’ couldn’t be any happier. With a mischievous giggle, she pointed to the self-blinded and deafened commander of the Royal Guard.

“Alrighty, boys! Hold him down and, like, keep him staring at my totally tasty twerk-tush!”

“Yes… Princess…” The soldiers spoke in unison, their stiff bodies suddenly rushing forward to snatch their commander. However, before they got a chance to grab hold of him, the first was quickly tripped and knocked down with a leg sweep.

“Ha! Still green compared to me!” The commander smirked, opening his eyes just enough to look down in confidence at his first dodged cadet before quickly moving to the next and trying to take him down with only his legs. Then the next, then the next. Before long, he was moving seamlessly from one opponent to the next as they barreled forward mindlessly to try and grab him. It was evidence to Eris as to why this one was in charge.

However, that momentum could only last so much. Regardless of how hard he knocked his own butt-notized soldiers down, they got back up just as strong as before. Meanwhile, the commander felt his own body slowly get worn down, especially when he was doing his best to fight and block out that distracting butt in the background. That mission was also not going well, for whenever he was moving, he caught glimpses of that perfect posterior in his peripherals, and soon, it was in his vision for milliseconds, then actual seconds. Even if he couldn’t hear it, the clapping was still reverberating in his head every time they swung, jiggled, and clapped. No matter how hard he tried, he couldn’t resist the butt…

BONK!

And those moments of weakness were just enough for the poor commander to be done in by a whack on the head, his head turning back as he stumbled about to see a soldier he lost track of wielding a stick. Before he could regain his footing, his arms were grabbed, then his legs, and he was dragged towards the princess who smirked victoriously.

“Awww, poor widdle cum-mander~” ‘Celestia’ snickered, cupping his chin only to have it pulled back.

“I don’t know what you did with the princess, imposter! But don’t think you’ll get away with this!”

“Awww, but like, I’m not an imposter!”

‘Yes you are!!’

“Silence, butt-slave!!”

“I’m totes the real deal! Here…” Celestia slowly turned around, rubbing her own ass. “Lemme show ya…~”

Slowly, Celestia moved down to a low squat, nodding to her boombox slave who turned a knob to turn the music up. Suddenly, Celestia’s ass widened as she began to shake harder than ever before, right in the commander’s face. His head quickly tried to look away, but he suddenly had his head held in place. When he tried to close his eyes, they were forced open, leaving him no options but to stare at the ass consuming his vision.

His mind stood no chance. Even as he tried to think of anything else, drill formations, fighting, secrets he knew, one by one it was all dissolved and replaced with butts. Big royal asses. Perfect princess posteriors. It was all being replaced with the sexy Princess Celestia and the dumptruck she swung around recklessly. Soon, the cadets didn’t even need to hold their commander’s eyes open or even hold him in place. His struggling had been reduced to meager twitches as soon, the armor around his crotch began too tight for him while his mind was lost in an endless ass-byss.

SNAP!

The uncontrolled mind of Celestia groaned in dismay while Eris cackled away as the last of the guards had submitted to ‘Celly Sunbuns’ and her hypnotic booty.

“Well, Celly! Looks like you’ve REALLY gotta hire better guards! They can’t even beat one fine ass!”

‘M-My guards are perfectly competent, Eris! Don’t let this little trick of yours be the only judge of them!’

“Oh yeah~?”

‘… Oh no…’

“Alright, my silly guardies! Time to make my royal decree, like, clear and stuff!” Her hand slapped her own ass as she continued to bounce it. “Celly Sunbuns says no clothes.”

“Celly Sunbuns says no clothes…” They mumbled in unison as, one by one, they began to strip themselves of their armor. Their spiral eyes stared forward as they mindlessly moved to make themselves naked, each of their hardened cocks pointed upward and hard still as they were freed.

Even controlled, Celly stared at the hard cocks of her guards with blushy cheeks, licking her lips in excitement as she slapped her ass again. “Good! Your swords gotta be out to like, protect my big buns and stuff! Now, let’s see how good you are with them! Grab those swords, boys~”

“Yes… Princess…” In unison, they all grabbed hold of their stiff cocks which all reacted with a twitch in excitement.

Snickering in delight, Eris had Celestia squat low for them before giving her twerks a fast rhythm. “To the beat with me, meat slaves!”

The guards quickly spread their legs and began to stroke to the beat Celestia’s booty claps. None showed an ounce of shame for masturbating in public, nor any emotion besides mind-melting horny. All they wanted was to obey and serve Celly Sunbuns, beating off their cocks. As they did so, Eris got herself another fun idea and snapped her fingers. At first, it didn’t seem to do anything, but the more the guards stroked themselves, the more their twitching cocks began to grow. Bit by bit with every pump, they grew in length and in girth. Their sacks began to grow with their cock eventually, swelling in size and weight as if filling with cum. Soon, they were taking the cocks in both hands and thrusting into them, their breath heavily leaving their open mouths.

Even as their cocks needed to be two-handed, they didn’t dare stop. They weren’t ordered to. They obeyed Princess Celly Sunbuns. Their tips leaked in precum as they felt themselves about to cum…

“No cumming!” Celly declared as she looked back at them. “Not until Celly says so!”

“Yes… Princess…” And so, they were forced to hold it in, always riding the edge while staring at their princess while their cocks twitched in their hands.

After what felt like an eternity for all of them, Celestia’s body suddenly stopped and snapped its fingers. On cue, the guards took a standing salute while their enlarged cocks dangled and twitched in a desperate need for release. As everyone panted from the strain, Eris finally spoke up.

“Soooo, having fun so far…~?”

‘I-I’m… Going… To send you into… Oh, Faustia… I can’t feel my ass…’

“Well, how about I let you speak a bit?~ Give you a biiit of free reign over your body~”

‘… Are you serious…?’

“Very serious! Just so long as you don’t try to do anything too rash!”

Suddenly, Celestia’s body jolted a bit, and she felt the metaphorical puppet strings controlling her slip just enough for her to finally frown. She turned and saw her subjects, completely brainwashed by her own ass and masturbating without shame. The guards were no better, with modest dicks of varying sizes now all the length of an arm and saluting like the bodies they were attached to. She needed to find a way out without Eris knowing, even though she knew that Eris knew what she was thinking. But she knew that Eris knew what she-

“Oh for goodness sake! Are you going to actually say anything to your subjects, or do I have to do something myself??”

Rolling her eyes, Celestia figured she’d have nothing to lose at this point. She opened her mouth, moving to the ear of her commander as she let out a hushed whisper. “Commander… I need you to-GIVE MY FAT ASS A GOOD SMACKING!”

‘Dangit!!’

Her body spun around, sticking her ass out and shaking it at the commander in anticipation. Celestia closed her eyes as she braced for the hit… But the hit never came. No matter how long she waited, it never really came. She opened her eyes, visibly relaxing.

SMACK!

“GEHEEEEEEEE~!!”

And Celestia practically sprung up into the air from the intense slap her ass just received. Landing back down, she moved her hands back to rub her cheeks at the point of the red handprint while Eris was cackling in her mind.

“I-In retrospect, I knew that was going to happen…” Celestia grumbled into the dirt. “I shouldn’t have taken the bait…”

“Yeah, well next time, try a code word or another strategy~” Eris snickered as she ethereally watched Celestia nursing her ass. “Oh get over it. You’re telling me your fat flanks aren’t trained for spanking?”

“No!”

“Oh. Huh… Well, I know just the way to fix that!”

Celestia’s body suddenly zipped back to a standing position, her body totally immobile now as a pair of maids suddenly had riding crops in their hands. Only her mouth was able to speak up as she grunting in frustration. “E-Eris, what are you-?”

SMACK!!

“YEOUCH!”

Before she could finish, one of the maids smacked at one of her flanks, making it jiggle as her legs began to march forward. “W-What…? Stop this nonsense this-!”

SMACK!

“YIPE!!” The other maid smacked the other flank and Celestia’s hands stuck out forward on their own. The princess struggled against her own body as it began to walk forward like a zombie, marching through the training area while her head tried to pull back as if to reign herself in.

However, she didn’t get that luxury, as with another hard SMACK, her resistance stopped for just a moment as she kept on going forward. Over and over, she tried, only to get a SMACK and march a bit faster with a squeak. Every little resistance that wasn’t zombie marching around the palace was only to be met with a harsh slapping with another good smack of her cheeks by the maids, and her brainwashed subjects followed along, dropping the remains of their clothes until they were as bare as their princess.

“I said stop, every-”

WHACK!

“OWIE! Hey, cut it-!”

SLAP!

“OOWWWT! Please somepony, kick this-”

SMACK!

“Chaos-crazed idiot out of my-”

SMACK!

“Heeeead!”

~

Celestia’s body would eventually come to a stop at the throne room, with her entourage stopping alongside her. She seemed to be less exhausted by the ‘trip’ than what happened before, but her ass paid the consequence instead. It was bright red, spank marks littered all over those once white globes. It more resembled a big baboon butt than her own pristine white flanks. Eris snickered as she popped out of the princess’s ear.

“Well, now! Look at how far you made it! All the way to the throne room!” She smiled brightly at Celestia, who was forced to smile right back with a snap of Eris’s fingers.

“Y-Yeah…” Celestia said through gritted teeth. “I suuure did a good job.

“Super good, Celly Sunbuns!”

“Y-Yup, that’s me…” She giggled slowly, hoping that Eris would finally go easy on her. “M-Maybe… Good enough to give Celly a reward…?”

“Hmmm… Ya know what? Maybe you DID do a good enough job for a reward!” Eris flew out of Celestia’s ear, making the mare moan with wobbly knees while the draconequus slowly took a seat on the throne and held out her pinched fingers the princess. “So, prepare yourself, Celly Sunbuns! This is gonna be the best present you’ll ever get!”

Celestia let out a small sigh of relief. “Th-Thank you, Eris. You are truly-”

SNAP!

Celestia suddenly stood in place, smiling brightly as her body and mind was now puppeted by Eris. Her legs slowly spread as her ass began to shake, smiling back at the crowd. “Alrighty! Who’s ready to fuck this big fat princess booty? Cause I, like, declare an immediate orgy! All the big cocks fill me up first before using those other sluts! Thus decrees Celly Sunbuns!!”

“Yes… Princess…” The brainwashed crowd mumbled and immediately a flurry of action began. The male members, their cocks enchanted to huge, stiff poles, slowly began to form a line up to the thrones where Celly Sunbuns moved to and show off her body to them eagerly. She moved to the first one, grabbing hold of his dick and stroking it fast before shoving the tip into her mouth. Despite how huge the cock was, she eagerly took it in her mouth, bobbing her head up and down and moving lower and lower. Amazingly (and with a bit of magic on Eris’s part), she took the whole length down her throat as she used one hand to fondle the guard’s balls and another to rub her damp pussy.

Suddenly, she felt somepony grab onto her thighs and hoist her up. With a quick turn of her head, she spotted another guard, too pent up to wait as his huge cock plopped between her fat, sensitive asscheeks. A groan of pleasure tried to escape her lips only to be blocked by the huge pole she was deepthroating, but she quickly moved to bounce her ass up and down in order to hotdog the cock as a signal for the guard to shove it in. The guard obeyed, slowly moving his hips back before pushing his cock inside of Celly’s pussy with a grunt.

“M-Mggk-Ohhh, heck yeah~” Celly’s mouth was quickly freed of the cock in her mouth to emit the groan of bliss while her eyes slowly rolled up. Her ass seemed to move on its own and rapidly rode on that rod currently ramming her rump. The guard’s thrusts soon matched with Celly’s bounces, loud slapping echoing throughout the chamber and blending with the princess’s moans. However, the moans were quickly silenced when the other guard slammed his cock back inside and assisted in spitroasting his ruler. After what felt like long hours, their cocks began to throb, urging them to speed up, to which they dutifully obeyed. After ramming Celestia over and over, they finally gave one thrust before painting her womb and throat full of cum. Their balls clenched as seed spilled out over and over, some spilling out onto the floor and out of her nose. Eventually, they pulled out and walked off to fuck one of the other sluts in the chamber.

Celestia wouldn’t get a chance to rest, as she paused to pant for a whole 10 seconds before two guards hoisted her up and hovered her over her rodes. They gave dirty grins to each other before dropping the princess down, impaling both her ass and pussy at the same time.

“Ahhhhh~” Celly cried out as she arched her back into the guard, feeling two hard dicks roughly massage her insides in sync with one another. Neither let up, one gripping hard on her thighs while the other squeezed her ass tight. The feeling of being fondled and used like a toy was something she’d not felt until today, and it… Wasn’t so ba-

‘N-No! Fight it!’ Celestia tried to resist, shaking her head and trying to resist bursting into a goofy smile. ‘C-Can’t… Let Eris fill my brain with big… Fat… Cooooock…~’

Suddenly, three pegasi flew above the princess, hard cocks at the ready as they waved them about in her face. It wasn’t even a challenge to get her to stare at them, wide-eyed and drooly. It was like they had some gravitational pull on her mind, replacing anything that wasn’t sex and dicks with ONLY those two things. Without hesitation, she grabbed hold of two of them, feeling the pulsing in her hands and getting even more aroused as she began to stroke them. Then, all she had to do was open her mouth to accept the next cock and groan as it easily slammed into her throat.

She could feel it all, her eyes rolling up as she accepted every inch of it down her throat. She felt it push deeper and deeper down her throat, huffing his scent without shame as her legs wrapped around the guard currently ramming her wet twat. Her hands moved faster, rapidly fapping the cocks aimed at her face. The poor princess’s mind felt like it was short circuiting in ecstasy, her tongue rolling around the cock in her mouth. She didn’t want it to stop.

However, the twitching cocks told her that it was time for her to receive her next shots of protein in the form of five heavy loads of jizz. She pulled her head back and allowed the cock she was sucking on to aim right at her face before it was completely coated in jizz. Some shots even made it past her face and coated some of her ethereal mane. She could feel it absorb into her as the cocks inside of her dumped her loads, moaning with the dumbest and bubbliest of giggles. She wasn’t done. She needed more…

As she pulled herself free, she didn’t even wait for the next set of stallions to approach her. She grabbed hold of the next in line and pushed them to the ground, hovering her pussy against the tip and swaying her hips provocatively.

“Like, ya want this, stud? Wanna fill up your princess and make her all sticky and stuff~?”

“Y-Yes… Princess…” The stallion groaned out, pleasure breaking through the conditioning as even he felt through this. Celestia giggled and dropped straight down with the most perverted of sounds escaping her. She squatted up and down, panting as she stared up at the stallions who approached her. She didn’t waste time, grabbing hold of their sacks and fondling them while sucking on one of their tips. She could feel the weight of them in her hands, so huge and sloshing with that precious cum her body craved more than anything. She switched between the cocks, slowly moving lower on them just as she was doing with the cock she was sitting on. She never questioned how she was so good at satisfying the needs of cocks this way. Somehow, this was just correct, the thing a princess was supposed to do. She never equated it to Eris, who laughed at the state of the princess while rubbing herself with a confident grin.

While the princess continued to service the seemingly endless line of cocks, the female members of the castle did their best to ensure that the stallions all stayed aroused in line and serviced the ones who were done using Celly Sunbuns. Some would make out with one another, their tongues dancing in each other’s mouths as they explored each other’s bodies, others would begin dancing around in provocative ways to keep those cocks up. Bellydancing, twerking, naked ballet to expose their holes, anything to stir up those needy cocks enough to prevent them from going limp. Some would even start fondling the males in line in a teasing manner, whispering little taunts in their ears.

“Oh, you like that, stud…?”

“Bet you wanna stick it in us too…~”

“Ah ah ah… Only AFTER you give Her Royal Sluttiness her much needed seed…”

The taunting had the well intended effect of arousing the stallions to the point of nearly cumming, but none of them were able to. With a snap of Eris’s fingers, all of them had a lock appear on their aching balls. So long as that was there, no one was cumming an ounce. Instead, they dribbled precum on the floor as they stroked themselves hard, panting and humping at the air, desperate for release.

Once the stallions had finished inside of Celestia, the limit was off, and they could go crazy with the many mares still teasing and taunting the line of stallions. They grabbed hold of a mare and groped their body, and the mare responded with giggles and coos as they rubbed right back.

“Oh my~ You got a real big one on you…”

“You wanna use it? Go ahead and stick it in…”

“Let’s give these stallions a show…”

Their inhibitions destroyed by brainwashing, they parted the mares’ cheeks and slammed their cocks in without shame. The mares would let out loud, pervy moans as they pumped over and over, their insides finally full of dick. It didn’t matter if they were maid or noblemare, guard or cook. They were to fuck, as decreed by Celly Sunbuns. Well, perhaps not decreed. More like, suggested. That was enough for their tiny, sex-fueled minds. All they wanted to do was fuck, and as stallion after stallion emptied his balls into the princess, they would turn the entire place into one big orgy.

Eris couldn’t be any happier. She’d expected to have failed quite a while ago, perhaps leading to a 3-part story that eventually ended in some level of satisfaction. She admired the work she’d put on and rubbed her pussy in excitement. Of course, that wasn’t quite enough for her…

“Hey, slut!” Eris shouted to Celestia, mid-doggy style with one of the guards. “Bring your fat flanks over! Your mistress is in need of your… Services…~”

SNAP!

FLASH!

Suddenly, Celestia found herself met face to face with Eris’s snatch, her instinct being to dive in and begin eating away. However, she only got a bit close when she suddenly felt Eris grab onto her horn.

“Ah ah ah~ I don’t need that floppy cock rag. I prefer…” She moved the horn about, slowly guiding it into Eris as she moaned in bliss. “Ahhhh~ That’s it~”

Celestia felt the chaotic pussy consume her horn, the odd tingling on her horn making it feel extra sensitive. It was like she was getting stimulation sent directly to her head, pouring that delicious feeling that caused her to squirt juices all over the guard right behind her. Combined with the cock still slamming into her snatch, it was even better than the last. Every thrust forward and back made her head instinctively move back and forth, her rationale now melting down further. Instinct took over, and her identity was melting along with that white hot goo being dumped into her.

One of the last thoughts she thought before her brain went into cave-mare mode was as eloquent as her face looked.

‘Uuuungh~ C-COCK!!! COCK IN CELLY HOLES!! CELLY FILL CUM HOLES!! FILL THEM!! BREED BREED BREED BREED BREED BREED BREED BREED BREED-!!!

~~~

Eris wasn’t sure how long she’d had the ponies of the castle fucking. A few hours, half a day, maybe more. Eventually, one by one, the sex-brained ponies would gradually collapse from exhaustion, one by one. It wouldn’t be until the final pair collapsed on the pile that Eris could look at the wasteland of erotica she’d created. Stains littered the floor and walls, decorations knocked over and made a mess, and the whole area had the scent of an orgy that the chaos deity couldn’t get enough of. Now, it was just her and Celestia, who was rapidly lapping away at her mistress’s cunt. The fact that she was even coherent was a miracle, honestly. However, it was clear the princess was close to crashing herself. Her arms and legs wobbled, her gaze was dull and blurry, and everything she did was stiff and robotic. It was hard for her to even tell if she was brainwashed or not.

Truthfully, it was surprising to Eris that so many members of the court had held out for so long. Some had been fucking for hours and hours without stopping, and those she would keep an eye on for another time. However, it would definitely arouse some level of suspicion if things didn’t get put back to normal. Even now, she could tell that if she didn’t put things exactly as they were, she was going to be making herself comfy in a stone statue home, and no amount of pleading with Fluttershy would be able to mend that. So, with a smile, she took a disembodied hand and slapped the alicorn’s ass.

“Good news, Sunbuns! I think I’ll be letting you go in a bit! Buuuut…” Eris waved a floating finger back and forth. “It wouldn’t be right if I didn’t cum-tribute to your little pot of white gold! Although, to call it little…”

She admired the sloshing, cum-filled stomach of Celestia for a bit, humming before snapping her fingers. Suddenly, most of that was suddenly distributed to the ass and tits of the mare, doubling her hourglass figure. All Celestia could do was groan in bliss before returning to her instinct of intense chaos cunnilingus.

“Awww, look at you. So docile, so obedient… So sexy~” Eris slowly lifted Celestia’s chin with a finger, looking down at her from her temporary throne. “It’s almost going to be a shame to let you go free… But, we can’t have me get turned to stone again! How could I mess with you, then??”

She giggled as she watched Celestia licking away at the air, letting go of her sticky mane. “But, let’s see if we can’t fuck you to sleep. And I know just the tool for the job…”

One snap later, and Eris’s nethers changed in a flash. Once sporting a pussy that had its own appearance, much like her other body parts, now she had a large horsecock, easily trouncing the other cocks that Celestia had just went through. Of course, in her state, it was cock, and Celly fucked cock. Without even being given a command, she leaped towards the cock and wrapped her lips around it, sucking the cock as if she were desperate for some sustenance. Even as her energy had been drained for the seemingly endless orgy, she was still desperately trying to pleasure Eris’s enormous cock.

Eris grinned as she watched Celestia bobbed up and down on her new cock, the once elegant princess now a stupid cumslut. She grabbed her cum-coated mane like handlebars, thrusting down the mare’s throat. She watched as Celly’s eyes rolled up, cheeks puffing up as she did her best to take every inch. Eris’s balls slapped at her slut’s chin until eventually, she felt Celestia grab hold of her nuts and massaged them like a true whore. She licked her lips eagerly at the sight of the princess.

‘I’m the best…’ She thought to herself. ‘Maybe I should make this whole thing a yearly tradition…’ She watched as Celly managed to take the cock to the base, which caused the draconequus to cock her head back while gasping in bliss.

“Ohhhh, yes…” She groaned, her sack tensing a bit as buckets of precum leaked out. “Been a while since I really used this thing… But I know I’ve been saving room for the real thing…”

Roughly pulling out of Celestia’s mouth, which left her gasping for breath, Eris snapped her fingers, which caused the heels to glow once more. Celestia slowly stood up, strutting to her throne. She moved down onto her knees, and then moved forward and rested her arms onto the seat. She was left sticking her enlarged ass out, shaking it from side to side.

“Hehehe, good pet…” Eris mumbled as she approached Celestia. She grabbed handfuls of ass with her claws, roughly kneading it in her hands and listening to the tune of her toy’s greedy moans. She could hardly wait as she slammed her massive dick between her cheeks. Celly moved to stroke the cock between her ass while Eris mounted her, the alicorn awaiting penetration with a forced smile.

With no ceremony, she rammed her cock inside with a soft groan, feeling those slick nethers grip tight around her cock. It was perhaps the best she’d ever felt, with the mixture of love juices and cum making the best lube for her. Even though Celly had been fucked countless times at this point, her cunt was still as tight as ever and gripped Eris’s cock like a vice. It pushed her to thrust harder, licking her lips as she gripped on the ass in front of her. The sounds of loud, wet slapping filled the now otherwise silent throne room.

“Mmmph, fuck…” Eris mumbled through clenched teeth, slamming her hips harder and harder. “If only I could fuck this pussy every night and day… Actually…”

Suddenly, an idea popped into Eris’s mind, one that could get her exactly what she wanted. She grit her teeth as she pounded away, feeling her magic pouring into her balls for the biggest nut of her life. She pulled Celly close and squeezed her tight, as if using her like a sex toy. She leaned down and slammed her hips downwards, punishing Celestia’s cunt over and over while continuing to hold on to her seed. She centered the chaos magic’s flow in her into her cock, with that new idea fit within her mad mind.

“Nnngh, so cloooose…~” She moaned as she fucked Celestia, her breath hot and heavy as she gripped on the thighs of the transformed alicorn. She wanted to have fun like this every day, her cock pulsing with excitement as she picked up the case. More precum slivered out, staining to keep it all in. She slowly bottomed out into the princess…

SPLURT!!

“Ahhhhhhhh~!”

As her enormous testicles tightened up, her cock spilled tons of colorful semen down into the princess’s womb. The multicolored goo flooded Celestia, her belly distending outwards as she took more and more into her. It was a sensation that made the mind-controlled mare’s brain finally and fully short-circuit as she collapsed backwards in bliss. She drooled over herself, her eyes closing as she became unconscious from the pleasure of being filled over and over. It was as if every inch of her was made of cum and bliss, that this was all she needed. Only when Eris finally finished that she pulled out, seeing the cum balloon that was now Celestia’s belly.

“My Celly, you sure do fill up nicely~” Eris giggled as she poked at Celestia. “I wonder what would happen if I…”

She pushed down on Celestia’s stomach, causing the multicolored cum to spill out and pour onto the floor. However, rather than forming a puddle, it slowly formed shapes, as if being poured into a mold. As this happened, Celestia’s bimbofied features slowly dissolved with her returning to her normal form. More and more cum spilled out, and more of this form took on a more definitive shape. Eventually, as Celestia’s body was returned completely to her appearance before this entire fiasco began, and the cum was made into a sex doll recreation of Celly Sunbuns, complete with self-lubricating holes.

“Ah, she’s perfect! I’m gonna have fun toying with this one day in and day out!” Eris giggled as she looked back at Celestia. “Don’t worry, Celly! I won’t forget you~ I’ll come back to play another day…~”

With a boop and a giggle, Eris snapped her fingers over Celestia, removing the heels and replacing it with a set of soft pajamas before putting her in a sleeping bag. Next, she performed the same action over the passed-out ponies in the courtroom. Their bodies returned to normal, their clothes returned to normal, and their minds were cleared of this whole incident. A magic wave flew over the castle, cleansing it of any trace of Eris’s shenanigans. In place, all of them would instead be wrapped in sleeping bags. With that, she took a bow and vanished in another snap of her finger.

Nopony quite remembered why everypony decided to have a slumber party in the castle, but they’d all wake up sore and ready to sleep in actual beds. Celestia, for her part, absolutely did. She acted as if nothing was wrong, smiling and telling everypony that she wanted to have a bonding exercise among the many members of the court, guard, and staff together, and everypony just went along with it. The princess let out a sigh in relief and continued to go about her day.

“I should probably check on Luna…” Celestia thought as she walked through the halls leading to her sister’s room. “I know we had an experience, and she hasn’t said anything about what happened… Still, best check on her first.”

She slowly approached the unguarded door to Luna’s chambers when she heard something. Something… Rhythmic, like the sounds of clapping. Her eyes widened slightly in realization. “No… It can’t be…” Celestia’s eyes widened before bursting into the room.

“Luna what’s-??”

“Sis, like, help and stuff!”

There Luna was, totally naked save for a familiar pair of red heels and a smile forcefully held by magic on her face. She was squatting low, throwing her ass back and twerking shamelessly before her sister while giving out a dumb, bubbly giggle.

“I like, found these totes cute heels and wanted to try them on! Now I can’t stop, like, twerking my fat ass!”

“I-I thought I got rid of those! How did they get back??” Celestia thought as her eyes suddenly focused on those huge, navy blue flanks wobbling in front of her. “I need to use magic to save Luna before… B-Before… Buhhh… Butt…”

Celestia leaned forward, eyes becoming enraptured in that ass, her mind hearing a familiar, devilish giggle…

Author's Note

Hope you all enjoyed. I have been getting more and more commissions, every single one of them huge which is why I can't really focus on personal projects. I'd like to, but money beats passion, and I don't think I'm popular or even good enough to set up a Patreon or Subscribestar whatever. Plus, I've got classes. Still, I'll try and post more stuff in general, both here and on FA.

So sorry for the delay. Thank you all for the patience.
