You Are All I Need (And Then Some)
All I Need
The door to the throne room opened gently, making barely a creak. Celestia looked up from her place on the throne where she slouched, having had no royal business all day and easily being able to afford the luxury of laziness. She smiled as she soon as she saw who had entered.
“Ah, hello there, Twilight,” she said, smiling at her former student. “How are you this evening?”
“Very well, Princess,” Twilight said, returning the Princess’s smile. “Extraordinarily well, one might say.”
“Oh?” Celestia asked, straightening up in her throne. “What brings you into such a great mood today?”
“I’ve had an epiphany!” Twilight said, her wings rustling as she spoke. “No small part thanks to you bestowing these wings to me, of course. In fact… it’s directly related to my new position as a Princess.”
“I see. Care to share with me?”
“Mmm, yes.” Twilight took a few steps closer towards the throne, the soft evening light casting long shadows across the room. “You see, Princess… I’ve been thinking a lot about how things have changed now that I’ve got my wings. Now that I’ve been tasked as the Princess of Magic.”
“Well, not too much, as luck would have it,” Celestia said. “Certainly, you have more duties to fulfill, but naturally you were gaining more and more responsibilities while you were in Ponyville. You would have been a princess in your own right even if you hadn’t completed Starswirl’s spell. In fact…” she tapped her chin, horn glimmering slightly as the the sun slid down just a little bit more. “I believe the only drastic change that isn’t physical would be that you are no longer my student and have instead come into your own as a princess.”
“And that’s just the thing, Celestia.” Twilight was now just a few feet from the throne at this point. “I’ve exceeded your ability to teach me. I’m a princess now; your equal.”
“Well, I don’t like to put on the air that I’m superior to my subjects—“
“And yet, you clearly are,” Twilight interrupted her. “There’s no denying that. In fact, you were superior to me for a long time.”
“But now that we’re both princesses, we are equal.” Celestia nodded. “Yes, I can see this. We are the same, yet different… rulers of great power but in differing aspects.”
“Well, see, Princess,” Twilight said with a chuckle. “I don’t think our power is all too different.”
Celestia raised an eyebrow. “Oh?”
“Yes, as a matter of fact, I think that our powers our very much the same. Why, I feel as if I could raise and lower the sun myself!” Twilight’s face broke out into a manic, almost sadistic, wild-eyed grin. “So I did.”
Celestia felt her heart skip a beat. “Excuse me?”
“I raised the sun by myself today, Princess.” Twilight stood where she was, maddened smile still plastered to her face. “I woke up extra early and even though it took great concentration… I raised it all myself. And after the initial headache, why, it was hardly any trouble at all.”
Celestia stared at Twilight, mouth agape.
Twilight chuckled and looked down at her hooves for a moment before lifting her head to resume eye contact with the princess. “Really, it’s quite remarkable that you didn’t notice today. I made sure to do it just a moment earlier than you, though—I have all sorts of sun and moon charts to reference to make sure that I could start earlier enough so that I would be sure it was me who rose the sun, but late enough so that you could mistake it was you who was doing your regular work. Why… I’ve been lowering the sun this entire time and you haven’t even noticed!”
Celestia’s mouth went dry. It had been remarkably easy to raise the sun today… but she had felt that she may have just been more on point than usual this morning! She tried to reconcile with herself that perhaps it was easy because Twilight had been aiding her, and they had done it together, but she knew this was denial as soon as the thought crossed her mind; raising the sun was a singular effort.
“Th-That’s…” Celestia swallowed. “That’s remarkable, Twilight.” Her voice came out as a rough croak, as if her throat had been lined with sawdust and cotton. “I had n-no idea you had grown so skilled.”
“Yes, and the proof of my power this morning solidified a line of thought I had been entertaining since I was first bestowed my wings and you informed me that I was no longer your student…”
“And that is?” Celestia could hear her heart pounding in her ears, and she knew that she would fear the answer.
“I no longer need you,” Twilight said, her grin growing to insane proportions. Her horn sparked, and Celestia saw purple sparks fly around her. Petrified, she slowly levitated as a pale lavender aura surrounded her.
“Twilight!” Celestia gasped. “What are you doing?”
“I’m utilizing you in the most useful way I can think of,” Twilight said, chuckling. “I’m going to let you become a part of me, Princess. Truth be told, Equestria really only needs two Princesses… I’ll be letting Cadance take care of Luna as she sees fit.”
“B-Become a part of you? Twilight, what are you talking about?”
Twilight opened her mouth wide, dangling Celestia a few feet above her head. Her stomach audibly growled, and Celestia’s pupils swelled in terror.
“N-No…”
“Oh, yes.” Twilight licked her lips, and opened her mouth again, her jaw unhinging even wider than before. “I’ve noticed how big you alicorns are… and an increase in my metabolism over the past few weeks that I’ve had my wings.” She giggled, opening her mouth yet again, her gullet extended even wider. “I figured, if I ever wanted any hopes of growing as large as you are, I’d need a big head start.”
“Twilight, please, you don’t have to do this…” Celestia whispered, trembling from head to hoof. “I-I would be more than willing to let you raise the sun in my place! It’s clear that your power is tremendous…”
“And it can be even more tremendous after I consume you,” Twilight said simply. “I’d be gaining all of your magical nutrition as well as your physical nutrition. You’ve got thousands of years of arcane magic stored in there, and I’ve got thousands of years ahead of me… I’m not about to let that go to waste letting you stick around with your only purpose robbed of you.”
“Don’t bother going for the guards," Twilight said, accompanied by a devious little chuckle. “I've sent them off. They trust that I'l be enough to handle their Princess, you see…”
Celestia closed her eyes, sobbing silently as Twilight levitated her closer to her mouth. Twilight’s mouth popped open again, even wider than before, a monstrous growl emanating from her belly. With a spark of her horn, Celestia jerked downwards, and her hooves popped into Twilight’s mouth.
Celestia tried to kick, but as she felt the impulse to do so grow, her muscles locked up. Twilight’s aura tightened around her, squeezing her into magical paralysis. She had to admit, Twilight’s mouth didn’t feel unpleasant—her tongue was soft and her former student’s maw was warm. This did little to assuage the complete, almost unbelievable horror of the situation.
“Please!” Celestia begged again. “Twilight… please…”
But it was too late; Twilight had already swallowed down Celestia’s hindlegs, and her snout was already buried firmly between her asscheeks. Twilight inhaled, smiling briefly around the mass of alicorn in her mouth. The scent was heavenly, thick and musky, causing Twilight to salivate even more than she already was.
This adds a much-needed erotic tinge to this already momentous occasion, Twilight thought to herself as her throat squeezed down on Celestia's legs, dragging them slowly but surely ever closer to Twilight's stomach.
With a shriek, Celestia slid even further into Twilight's gullet, her maw enclosing around her large flanks. Twilight’s cheeks bulged almost comically as her mouth struggled to contain the enormous ass of her former teacher.
“Twilight, it’s not too late,” Celestia called out to her former student. “Stop this! Stop this while you can!”
“Glurgh,” Twilight choked out in response.
Celestia groaned, her horn sparking. Something… something Twilight had done had sapped her of all her energy. Maybe it was a spell, maybe it was something in her saliva, maybe it was the sheer terror and absurdity surrounding the situation… but Celestia, no matter how hard she tried, could not summon up the magical energy to escape from Twilight’s clutches.
Another swallow from Twilight, and Celestia found herself slid down to her chest. Her front legs still stuck out, but her wings and the entirety of her body below them were wrapped in the warm, wet confines of Twilight’s gullet. The outline of her lower body formed an obscene bulge in Twilight’s throat, her shapely flanks and thick, powerful legs twitching and jerking, as if they could barely be contained by the predatory pony’s esophagus.
Twilight screwed up her face, eyes crossing as she struggled to gulp again. But while her throat contracted and pushed against Celestia’s lower body, the pull did not come. Celestia did not find herself sinking further into Twilight. Could this be it? she thought to herself. Could I still have a chance at escaping? Celestia couldn’t resist a smile; for the first time since Twilight showed up, she was beginning to feel somewhat at ease. With a small sigh, Celestia relaxed herself, getting ready to pull herself from the ravenous gullet she had nearly fell victim to.
The instant she relaxed the muscles in her legs and lower back, her slackened extremities gave Twilight the little bit of help she needed to successfully swallow again. In less than a moment, Celestia felt her hope fly away from her as she was jerked roughly even further into Twilight’s digestive system. The rest of her torso and her front legs were soon wrapped in the saliva-coated lining of Twilight's cheeks, and even sooner constricted in the tight, muscly tube below. Celestia gaped soundlessly, eyes wide and wet.
It couldn’t end this way…
She was now up to her neck inside Twilight. Her legs had slipped through a tight, muscular passage, and were now settled in a large, warm sack that could only be Twilight’s stomach. She felt an odd sort of numb sensation creep up her legs, small needles tingling through her flesh. She could feel her former student’s teeth clenched around her neck, digging into her coat and rubbing against the skin underneath. She could feel the wet, warm caress of Twilight's tongue against her lower jaw as it snaked around, licking and tasting her with little impunity.
Twilight’s horn sparked, a small arc of magic connecting with Celestia’s own. She let out a small yelp, her eyes going slack and unfocused, her jaw dropping open slightly as Twilight’s throat started moving once again. In a single slick, fluid motion (accompanied by a loud slurp!) Celestia’s entire head had slipped into Twilight’s throat. The bulge of her face was pressed out against Twilight's neck, and the only part of her still left exposed to the air was her long, white horn, which jutted from Twilight’s mouth like an overgrown tusk.
Twilight chomped down on the base of the horn, her strong teeth making a sharp clack! as they hit the surface of the horn. Grinding her lower jaw back and forth for a moment, the young alicorn searched for purchase along the protrusion. After a few seconds, she stopped, apparently satisfied with the configuration of her teeth to the horn. She opened her mouth wide, and bit down hard.
Celestia’s horn was neatly severed, falling to the flagstone floor with a clatter, rolling off a few feet to the side. Twilight closed her eyes, a bead of sweat trailing down her cheek as she swallowed down on Celestia. In one swift motion, she slipped downward into Twilight’s stomach, distending it almost comically.
“MRMPH!” Celestia’s groan of pain was deeply muffled by Twilight’s stomach. Still, she could feel the elder alicorn shifting and squirming inside her, desperate to escape now more than ever.
Twilight sighed, her body resting on top of her large, engorged stomach. She was easily five feet off the ground from where she usually stood, and her hooves were far from touching the floor. Giggling softly as Celestia thrashed and contorted inside her, Twilight rubbed her front hooves against the massive bulge.
“Bruup!” Twilight burped, her eyes falling to half lid as she looked down at where her former Princess was being held captive. “Phew! You sure were a hoofful to eat, Princess… but I managed to come through in the end, didn’t I?”
“Stop this right now!” Celestia’s muffled voice screamed from inside her. Twilight’s tail flicked back and forth, the tremors sending pleasing ripples through her body.”
“To think,” Twilight said, her horn glowing as she levitated Celestia’s disembodied horn up in front of her. “You were once so powerful. Soon, my body will have fully digested you, and your magic, your energy, will all be mine. I’ll be the powerhouse of a Princess Equestria needs me to be.” She giggled, rubbing her belly again as it let loose an enormous growl. “And you? You’ll be nothing but a pile of bones and excrement, my dear Celestia.”
“N-No!” Celestia’s voice shouted, strained and desperate. “Please!”
A few more groans and growls emanated from Twilight’s belly as it shifted around, the stomach lining clenching hard against Celestia as rivulets of stomach acid trickled around her, pooling at the bottom around her hooves and belly.
“It’l be over soon,” Twilight promised. A few more loud growls followed this, the sound almost enough to drown out Celestia's feeble moan.
“P-Please…”
Twilight hummed to herself, closing her eyes, her ears filled with the sounds of digestion. Now was the time where her body was going to do all the work, so she could just sit back, close her eyes, and…
***
Twilight awoke to a loud growling noise. She opened her eyes, and opened her mouth to let loose a yawn. However, instead a thick, deep braaaaaaap! escaped from her instead. Twilight blushed softly, her hoof moving to her stomach.
She could touch the floor again; her stomach had digested its large meal down to a manageable size, making Twilight appear to have simply let herself go over the past few months, instead of an over-engorged terror. With a small grunt, she hoisted herself to her hooves, and trundled forward towards Celestia’s throne.
“Well, it's not porcelain, but I think it'll be able to do the job all the same,” Twilight said to herself, chuckling. “I can’t think of a more fitting place for you to rest, don’t you agree, Princess?”
Her gut gurgled, and a familiar pressure began to build in the very back of it. Twilight smiled, and turned around, hiking her tail up as she presented her plot to the throne.
Grunting softly, Twilight’s anus puckered, her tail curled neatly against her back as to avoid it getting in the way. She screwed up her face in concentration, her legs spreading slightly as she focused on pushing. The first one’s always the hardest, she reminded herself. It’ll be smooth in just a minute…
With a sigh of relief, a massive, roughly cylindrical turd crowned from her asshole, falling with a wet pfuf onto the seat of Celestia’s throne. Twilight bit her lip and arched her back slightly as she felt another one snake down towards her rectum.
“Oh, this one is going to be—“ she began to say outloud, but was cut off by the sudden expansion in her backside. Twilight expelled a lewd moan from her mouth, just as her ass expelled a massive block of shit.
Turning her head to look at her work, she saw a single white spire jutting from the feces she had just pushed out. “Ah,” Twilight said with a small smile. “Look at that! That’s quite the impressive rib there, Princess. I’m surprised your bones were that durable—usually I manage to digest them along with everything else. Then again… the power you had should leave this as no surprise for me…”
Twilight’s monologue was interrupted by a loud protest from her bowels. Turning her head back away from her backside, she clutched her stomach with a hoof. “Nggh… oh, this is it, here it comes!”
Twilight let her jaw go slack and her eyes roll back as her anus stretched wide, a massive load of shit pouring from it. Unlike the first two chunks, this was not its own, isolated turd—this was the entire contents of Twilight’s bowel rushing and tumbling over itself in an effort to escape from her.
Twilight grit her teeth, the constantly stream of shit still pouring from her ass, her belly vibrating and contracting the whole while. She occasionally felt something harder and sharper move through her as she unloaded her massive dump, but that was soon replaced by the soothing, smooth sensation of a giant rope of uninterrupted shit. Finally, after what seemed like ages, Twilight’s ass pinched off the shit, allowing for it to drop into its massive pile on the throne.
“A-Almost,” Twilight grunt, pushing hard on her lower abdomen. She could still feel something—whatever it was—inside her bowel, churning and yearning to escape. This was too solid, too firm to be mere shit, though…
With a violent moan, Twilight pushed with all her might to expel the object inside her. Her asshole spread wide, wider than it had in a long time, and a bleach-white surface made itself present. Twilight took deep breathes, shaking head to hoof as she forced herself to shit out whatever this was inside her.
With a wet, immensely satisfying pop, it broke free, landing wetly on the pile of shit behind her. She let out a moan of pure ecstacy, a small squirt of femmecum shooting from her urethra and splashed audibly off the object she had just expelled. Twilight groaned, her clitoris winking slightly in the aftermath of her orgasm. Taking a deep breath, she let calm override her, and her urethra spread wide again, a heavy stream of piss splashing down upon the shitpile that had once been the ruler of Equestria.
“That’s a load off my plot,” Twilight said, grinning to herself as her stream of urine died down to a mere trickle before stopping all together. She turned around, and her eyebrows raised as she inspected the object that had given her so much trouble.
The blank, empty sockets of Celestia's skull stared back at her, and a few teeth still remained lodged in the upper jaw; the lower jaw was nowhere to be seen. On the forehead was a small spot of elevated bone in the shape of a circle, the surface smooth and clean-cut.
Twilight smirked, and patted her belly. “Well, well, Princess; this is the first time a skull made it through me. Quite impressive, if I do say so myself. It’s a shame the rest of your body isn’t half as resilient as your bones are, though.”
Twilight turned from the remnants of her former princess, humming softly to herself as she exited the room.
“I wonder how things went with Cadance and Luna…"
