A Forgotten Magic

"Pardon me Your Majesty, I believe Princess Luna is waiting for you in her room."
Celestia eyed the intendant, making an effort to conceal her annoyance.
"Thank you Grey Hooves, I will join her immediately."
The monarch crossed of a brisk step the hallways of Canterlot Castle, relieved to walk without a small battalion at her sides. Now that she had recovered all her strengths, she finally had the liberty to wander without watchful eyes following her every move. Not that the mischievous monarch minded the coveting glances on her lush behind; some of her guards seemed quite appreciative of her new figure. As soon as the kingdom affairs would be sorted out, Celestia was planning a quick detour by the royal confectioner's workshop. The memory of her carnivorous feast was giving the goddess nausea; hopefully for her, sugary treats had always been of great help when it came to get rid of unpleasant thoughts. After a few hours attending to her royal duties, the appeal of sweets was just growing irresistible. Yet she had to find the time to consult the magical archives; regaining a slender stature would be much more convenient with the help of an appropriate spell, as her mind was preoccupied by too many concerns to add to them an inconvenient diet.
As Celestia was finally entering her sister's room, Luna moved her graceful muzzle off her pillow, observing her with curiosity. She greeted her with a reserved smile.
"Dear sister, I am glad to see you back in shape."
Celestia gave a hint of a frown, as soon brushed off. She could have sworn her sister's voice had facetious accents. Luna slowly rose to greet her.
"I can see the remedy to your affliction had a few side effects."
Despite her younger sister's teasing, the Sun Goddess kept her composure.
"It had to be done. I know how it had been wearing for you to assume our respective charges."
The Night Princess brushed her neck against her sister's.
"I should have visited you yesterday..."
Celestia had a comprehensive smile.
"You needed the rest as much as I did."
They paused muzzle against muzzle, horn against horn; Celestia continued.
"If you wish so I could take your charges for a while. I can tell you could use some vacation."
Luna nodded in assent with a relieved smile.

"Twilight? Twiiilight?"
Hearing the young dragon, Twilight Sparkle suspended her reading. One of the archivists' voice interrupted him.
"Quiet! It's a place of study.
— Sorry, sorry..."
Leaning between the shelves, the purple pony waved to her friend. Spike joined her under the severe gaze of the archivist.
"Twilight! Want to join me for lunch?"
The hardworking student took a peek at the clock; she had been so absorbed by her study she did not see the time fly. Twilight Sparkle had a discreet blush as her stomach quietly groaned in agreement; her copious breakfast was no more than a distant memory. The studious unicorn put the agronomic treatise back on its shelf. She would have to remember to say a word to Applejack about it.

"And you tell me this dragon ambassador is from another continent?
— There is a whole country ruled by dragons in the east, they want to buy some of Equestria gems."
A waiter came in, serving the two friends' command. Spike bit delightedly in his gem garnished sandwich. He continued, his mouth full.
"I can't believe they let me have this."
Twilight Sparkle had a short laugh.
"Spike, your mouth!"
She started on her own dish, a salad of dandelion greens seasoned of croutons. Its honeyed vinaigrette was a perfect fit.
"Princess Celestia probably put a word in for you."
Spike lowered his voice, taking on a conspiratorial look.
"About Princess Celestia, did you see her today? She seems..."
Twilight Sparkle rolled her eyes.
"Yes Spike, I know. Don't worry about that."
Changing subject, the young dragon took upon himself to narrate the entirety of his time spent with his kind. Although the topic was enthralling, it did not stop Twilight Sparkle cleaning her plate while listening carefully the words of her friend. Meanwhile Spike had still to finish the first half of his sandwich, busy he was talking about his stay in Canterlot. The unsatiated mare waved to a waiter.
"Excuse me, can I have another plate of this?"
The customers were scarce in the restaurant, and her second order was quickly served. Twilight Sparkle started on her dish with appetite, though she was paying more attention to her loquacious friend than to the tasty salad she was consuming. Her plate emptied, the distracted pony realized Spike had not made much progress through his sandwich; her stomach had a discreet grumble. One thing was for sure, paying attention to the young dragon's incessant conversation was not filling her up. Watching her taking another order, Spike had a startled look; he could not remember seeing the disciplined unicorn eat with such drive. The pony's new course arrived, the young dragon's stupefaction redoubled. The garden salad was looking like a copious serving for two healthy stallions; countless clover sprouts garnished of numerous walnuts, hard-boiled eggs, goat cheese, grated carrots and cucumber slices, the whole liberally seasoned of a creamy dressing. Twilight Sparkle contemplated the hefty vegetable pile with surprise; it was much more than she had expected. Yet despite the two salads she just had, the thought of so much food before her was not the less intimidating. The hungry mare started on her copious course.
"Now than I think about it, there couldn't be a better place than Canterlot to learn more about cuisine."
Observing her, Spike had his eyes wide open.
"Are you gonna eat all of this? It's not like you to have so much."
Twilight Sparkle answered him between two bites, thoughtful.
"You're right, after the breakfast I had this morning I shouldn't be that hungry."
The young dragon seemed perplexed.
"What do you mean?
— I had a lot of pancakes for breakfast.
— A lot?"
The embarrassed mare blushed.
"Two dozen."
Spike had an incredulous expression.
"And you counted them?"
Twilight Sparkle had a self-conscious look.
"And half a dozen wafles."
The flustered unicorn began to speak faster.
"There was this breakfast cart charged with all these delicious things in my room, and I knew I wasn't supposed to eat it all but everything was so good, and once I started I couldn't stop..."
Spike had an appeasing gesture.
"Wow, wow, relax Twilight. You always figure things out, right? And it could be nothing."
Twilight Sparkle had a reassured look; if she had to, she knew where to begin her search.
"You're right Spike, I'll be fine."
The calmed mare observed her plate, perplexed. Grabbing his sandwich, Spike addressed her a shrug. Twilight Sparkle could hear her stomach groaning, barely protruding. She had an approving smile as they both resumed their meal. Cleaning her plate, the sated mare had a contented sigh; after such a feast, her soft belly had grown a noticeable bulge. Spike consulted the desserts menu, undecided before the vast choice of tempting confections. Twilight Sparkle had an interested look.
"Can I see?"
Going through the list of sweets, the curious pony prodded her rounded tummy, hesitant...

The gorged mare had an exhausted sigh as she finally entered her room, lying on her side on her comfortable bed. Twilight Sparkle touched her distended belly with a cautious hoof, listening to its churning sounds. She could not believe she had more food than at the Apple Family reunion, that day she met Applejack for the first time.
As soon as she had finished that filling banana split for dessert, Spike and her had left the restaurant. And if she felt slightly bloated after her copious meal, it was not enough to be a source of concern. But as they parted, Twilight Sparkle could not help thinking of extending her culinary knowledge in the most obvious manner. Rather to get back to the library, the intrigued mare had taken the way to the castle patisserie, resolute to learn more about all these appetizing items she knew the Princess had a fondness for. And the curious pony surely did, as she savored nun's puffs, éclairs, mille-feuilles, lattices and many more fruity or creamy confections. Her interest getting stronger at each mouthful had distracted her of her growing tummy, as it was rounding out to a sizable paunch. It was only once she had a taste of everything that she had retreated to her room, her belly now liberally spreading on her sides.
Something was not right, she had to talk to the Princess. Yet as Twilight Sparkle was patting the large mass of her jutting belly, she could only think of the cooking books lying on the shelves of the castle library...

Princess Celestia was biting her lips as she was rolling her bountiful hips in the hallways of the castle, her majestic behind drawing all eyes on her passage; she was simply dying for sweets. The few days succeeding her recovery had been punctuated of incessant snacking pauses, and not even the necessities of her function could stop her from nibbling constantly. Consequently the greedy goddess had not lost any weight, only growing fuller by the day. Her thighs had gained a luscious plumpness, and her juicy plot was more and more evocative of two pillowy globes. Her soft belly was rounding out, her sides sensibly bulging at all times; even her graceful neck had slightly thickened. Yet in her sister's absence, the monarch had too many responsibilities to take the time to consider such issue. Occupied by the kingdom affairs, Celestia had neglected for a few days to enquire about her protégée. It was hearing Spike's concerns that she had finally decided to visit her. Arrived at her guest's door, the Princess raised her voice.
"Twilight, are you here?"
A cheerful voice answered her.
"Princess Celestia! Please come in."
Celestia entered the room, and the first thing appearing before her eyes was a large and tantalizing red berries cake. Her mouth watered scrutinizing the creamy confection; raspberries on the top layer, strawberries on the middle and cherries on the bottom... a summer masterpiece. Twilight Sparkle's cheerful voice pulled her out of her contemplation.
"Princess, I haven't seen you for days!"
Celestia turned to her, observing the young dragon's source of preoccupation. Her favorite was lying on the floor, an open baking book at her side; she was surrounded by plates where only crumbs remained. The purple pony was eating the last slice of a rich mocha cake; her portion engulfed, she stood up with a visible effort. It became apparent the studious mare had not only devoured books recently; her rounding tummy was obvious to the eye. As they snuggled against each other, the Sun Goddess had a charmed look for the young unicorn. Twilight Sparkle had grown a comfortable cushion over her whole body, turning her to a quite chubby mare; even more conspicuous were the progresses of the pony's squishy paunch. Celestia mischievously poked of the hoof Twilight Sparkle's generous bulge.
"It seems you have grown quite an appetite yourself, Twilight."
The plump unicorn had a sigh.
"I wanted to tell you Princess, but since a few days I just can't stop myself... and the castle cooks keep bringing me food, whatever I ask them."
Celestia had an amused smile.
"It is their duty to serve our guests."
Twilight Sparkle had a concerned look.
"It has to be the spell, right?"
Her mentor nodded her assent; Celestia's eyes wandered on the tempting red berries cake.
"This... this seems delicious..."
The purple pony followed her gaze, hesitant to speak. She did not have to, as the door of the room opened.

The Sun Goddess was nibbling the last serving of the red berries confection, observing the full plates newly arranged around her favorite and her. Twilight Sparkle had ordered so many of them to end her day of self-indulgence...
As inexplicable as it seemed, the student was probably even more affected by the spell than her mentor. Hopefully, it seemed the charm protected her of the physical harm such excesses should usually lead to. As soon as the dishes had been served, Twilight Sparkle had resumed her banquet, eating conscientiously slices after slices of a dense lemon cream cake. The plate emptied, she had started on a peach garnished confection. Lying on the floor, Celestia observed her, fascinated by the chubby mare's appetite. The Princess knew she had to inquire about the issue, yet the occasion was irresistible. She prodded of the hoof her own soft belly, tempted by more after the red berries delicacy.
"Twilight, you wouldn't mind if..."
Twilight Sparkle articulated her answer between two mouthfuls.
"Of course Princess."
Making use of her powers, she offered a large slice to her mentor; they ate together, exchanging a knowing look. Her serving consumed, Celestia had a suggestive smile.
"Twilight, you don't have to show such restraint with me.
— What do you mean Princess?"
The Sun Goddess' hoof touched the pony's bulging paunch.
"I can hear it."
Twilight Sparkle seemed embarrassed; Celestia continued.
"I can feel you are distracted Twilight, as I am now. If we let that craving drive us, we won't be able to find a solution to this problem."
The perplexed mare sounded hesitant.
"Do you think we could get rid of it?
— I know we could quench it, at least for some time."
Twilight Sparkle had a worried look.
"You mean... like you did the other day? Princess Celestia, I don't know if I can!"
Brushing the pony's pudgy belly, Celestia had a comforting smile.
"You don't have to worry Twilight, I have no doubt we won't have to resort to such extremes."
The sensitive unicorn blushed under the Princess' touch.
"If you think we should."
The pleased monarch looked over the piles of food amassed around them; she whispered mischievously to her favorite's ear.
"But I doubt that will be enough for both of us..."

Pressed by her mentor's flattering words, little by little Twilight Sparkle was putting aside her inhibitions. Hesitant at first, she had consumed the rests of the peach garnished cake at quite a slow pace. Yet the Princess' encouragements were bearing fruits as she was pushing more dishes toward her; each vanilla cake slice had filled the compliant pony's whole plate. When the hungry unicorn started on the fruit bavarois, she directly ate in the serving platter, following the example of her gluttonous mentor. Before long, the empty dishes were cleared of the rooms as the Celestia's order was brought to them. Once again, the two greedy accomplices were surrounded by an ocean of sugary food. Finishing the bavarois, Twilight Sparkle rested her hoof over her enlarged paunch with a satisfied smile. She couldn't believe how good it felt to let herself go. Pushing a panna cotta toward her, the Princess had a gentle laugh.
"Twilight, I knew you would be more than capable to overcome that ordeal."
The tantalized unicorn blushed, looking with envy at the creamy dessert.
"Princess, I don't know for how long I can go..."
Celestia had an encouraging smile. The goddess herself had took her fair share of sweets, and her jutting belly was curiously appealing; it seemed like an invitation to self-indulgence.
"Twilight, I know you will more than meet my expectations."
Agreeing to these words, the bloated mare cautiously stood up, revealing her bulging tummy; for most ponies it would have grown large enough to be of great discomfort. Hopefully, with the help of her magic to support her weighty paunch, the overindulging unicorn was not suffering any major inconvenience. Twilight Sparkle raised in the air the panna cotta platter, landing it on a coffee table. She started eating the caramel confection; as expected, such position was much more convenient to her feast. Soon many more sweets came to the zealous mare, brought to her by Celestia's magic. Twilight Sparkle started polishing off platter after platter of rich desserts with the same jubilation. She was enjoying any texture or flavor, glutting herself with the same enthusiasm on crunchy chocolate, fruity mousse or creamy caramel. The chubby unicorn's belly was quickly expanding, accommodating the constant flow of sugary food. The pony's small frame compared to the Princess' tall stature was only making her fattening more obvious.
While Twilight Sparkle was eating constantly, carried away as much by her irresistible appetite than her mentor's support, Celestia had not forgot to treat herself with some delicacies of her own. The Princess had relished in a banana flavored cake, taking great enjoyment in gobbling boldly the whole fruits garnishing it. The exercise had tickled her for more, and devouring the cake itself had been a formality. Then the gluttonous goddess had set her mind on a large bowl of floating island; she had first consumed the light meringue, before gulping greedily on the copious amount of crème anglaise.
Celestia was feeling pleasantly heavy now, her rounding paunch displaying luscious curves. An instant she observed her favorite; plates were flying around Twilight Sparkle as the young mare was cramming herself with food. The pony's soft tummy seemed to grow wider before the Princess' very eyes.
This spectacle whetted Celestia's appetite, and for her next service the titillated goddess opted for an outrageous choice. The strawberry cheesecake was a sugary mountain, intended to sit in a reception; looking at the titanic piece, the Princess laughed inwardly of her own intemperance. At first she gorged compulsively on the cake, plastering with fruits and cream her gracious muzzle. Yet before long Celestia felt the fullness of her stomach, weighty of all the rich food she had already consumed; to her surprise, her appetite was already fading away. But something else had succeeded; the voracious goddess carried on her excesses, a light blush coloring her cheeks. She slowed down, struggling to eat even more. Celestia had absorbed eyes, reveling in each mouthful of sugary cream sliding down her throat; what she felt, it was nothing like the effect of the spell. Halfway through the monstruous piece, the binging goddess started feeling slightly nauseated, her inflated paunch becoming too strained to support her. The Princess dropped on her side, and as her royal hoof judged the tautness of her belly, she had a contented sigh. The empty plates were piling up around Twilight Sparkle, and Celestia noticed her favorite was already getting thicker. Could it be an effect of the spell? The pony's growing tummy was pressing against her legs, forcing her in a perilous position; it was doubtful the gorging mare could remain standing much longer.
Twilight Sparkle paused an instant, still savoring the heady flavor of the chocolate parfait she had just polished off. The original confections never-ending succession was intoxicating, and the captivated mare had engulfed with the same passion all the sweet dishes within her reach. The table was cluttered with empty plates, as so many evidences of her unrestrained binge. Getting ready to clear the table, the insatiable pony realized she was getting too weary to remain standing. Looking at herself, the changes occuring in her left Twilight Sparkle dumbfounded. It was no surprise she was so tired, supporting with her magic her absurdly bloated paunch. Three times as large as her back, her massive gut was down to her knees, feeling like a voluminous boulder hanging between her legs. Yet it was not the only change, as the chubby unicorn was already growing a fuller figure. She walked away of the table of a laborious step, lying on her back near the Princess. The ravenous mare perplexingly poked of the hoof her monumental belly, its skin still flexible to the touch. She observed the gluttonous goddess struggling to finish the scraps of cheesecake scattered on a reception platter.
Watching her favorite indulge in sweets with such fervor, the greedy Princess had long thought of that irresistible sensation possessing her. Her appetite had faded away, yet Celestia's desire to glut was urging her for more. Despite her stomach protests, the plumped goddess had resumed her feast, decided to consume the entirety of the gargantuan cheesecake. Forcing the rich food in her, the Princess was growing ecstatic. Her love handles were disappearing with the progresses of her belly curves, each mouthful stretching further the limits of her prodigious gut. Celestia seemed completely absorbed by her task, a lustful glint in her languishing eyes. Her immaculate paunch was growing distended enough to adopt the shape of a sizeable cask. The Princess finally swallowed the cake last morsels; her oversized paunch slightly rose as she stifled a hiccup of a graceful hoof. Rosy-cheeked, the ravished goddess had laughing eyes and a fulfilled smile. Celestia gauged her spectacular gut of an appreciative hoof; even without the influence of the enchantment, she had gorged to the point she was positively enormous. The gluttonous Princess was falling in love with that overwhelming feeling of fullness, yet for now she was incapable to eat another bit. She was not sensing the mark of the spell on her; meanwhile, its aura had only grown stronger on the young unicorn. The observant monarch noticed her favorite had proved herself in no way unworthy; Twilight Sparkle was resting her hooves over her colossal belly, its roundness evocative of a monstruous berry. To Celestia's delight, The purple pony's chubbiness was now turning ostentatious. There was no doubt in the goddess' mind the spell had its part in these accelerated changes. The overfed mare turned to her with a drowsy expression.
"Did it work Princess?"
Celestia had a considerate smile.
"I feel perfectly fine. What about you Twilight?"
Judging of the hoof her profuse tummy, Twilight Sparkle glanced at the plates all around her; quite a few treats were remaining untouched.
"It's getting better... but I think I could use some more."
Raising a dense black forest cake in the air, the playful goddess had a mischievous look.
"Twilight, I would be pleased to help."
Twilight Sparkle seemed apprehensive.
"I don't know Princess..."
Celestia snuggled against her favorite, their massive bellies touching. Feeling the squishiness of Twilight Sparkle's body, the flirtatious goddess stifled a gasp. Brushing of a considerate hoof the pony's enlarged paunch, the Princess brought to her the luscious cake, whispering to her ear.
"Twilight, we have to make sure you're thinking clearly..."
Pressed against her seductive mentor, the embarrassed unicorn blushed. She leaned on the black forest cake, cautiously tasting the rich dessert. Twilight Sparkle licked her lips, savoring the mix of cherries and dark chocolate. It was delicious, and how could she refuse anything to the Princess? The gluttonous pony slowly porked on the delicacy, the taste of liquor making her slightly light-headed. She was eager to eat all that food, spoiling her tummy like she never had before. The heavenly confection finally devoured, the complying mare let out a gratified sigh. Celestia wiped of her hoof the cream covering the pony's muzzle, tasting it with an impish look. The Princess petted with delectation Twilight Sparkle's billowy belly; the little unicorn was getting so pudgy...
The stuffed monarch could not indulge any more for now, yet she was willing to share; Celestia offered another platter to her protégée. Twilight Sparkle's appetite was nothing more than a distant feeling now, but she was still enjoying the food. And the Princess was so nice to her...
"Princess, I don't think I should."
Celestia had a caring smile.
"There isn't much left."
There was a mango charlotte and a lemon sponge cake, a chocolate torte and a pineapple butter cake... and that perfumed apricot pie Celestia was offering to her. Twilight Sparkle closed her eyes, smelling the tempting treat. A slice came to her muzzle, brought by her mentor's magic. A piece of caramelized apricot made her way through her lips; she gobbled the succulent fruit, her mouth salivating in anticipation. The plumped mare quickly grabbed the pie, pigging out on the enticing dessert. The platter cleaned out, she rested a hoof over her mountainous belly. The pudgy pony had a blissful expression; the sweet dish was barely weighing down on her swollen stomach. Twilight Sparkle suddenly noticed even her forelegs had grown soft and chubby. Celestia pressed her barrel-shaped gut against the pony's doughy paunch, her taut skin rubbing against her favorite's flab. Looking at Twilight Sparkle's eyes, she had an exultant smile. These eyes were all too familiar; the subjugated unicorn could not rest before she had put away any food in her sight.
The mischievous goddess put the mango charlotte within reach of the feasting pony, observing her crane her neck to take on the sweet dessert. The purple mare was heartily munching on the fruity confection, her puffy cheeks and her bangs moving at the rhythm of her mastication. So plump, and so cute...
The delicacy vanished in her gorged stomach, Twilight Sparkle caught her breath, her fat belly raising as a blown-up ballon. The Princess pushed the pineapple butter cake toward her favorite, observing her affectionately. Twilight Sparkle moved on her new course, relishing in her immoderate banquet. The all time rational unicorn was so excited to give in to her newly found sweet tooth. Despite its fruit filling, the butter cake was a rich and dense piece; the persistent mare took her time to cram the oily food in her stretched stomach, struggling against her sleepiness. The last crumbs wolfed down, the weary pony patted lazily her oversized belly. Twilight Sparkle had a blissful smile, won over by the taste of sweets. Yet she was so tired...
Celestia raised to her favorite's muzzle a slice of lemon sponge cake; the pampered unicorn submitted to her, taking a bit of the unctuous dessert. It was a pleasant taste, and Twilight Sparkle promptly gobbled the rest of her portion, pushing further the limits of her growing stomach. The gorging pony was blimping out, yet she did not want to decline any of her mentor's attentions. The caring goddess brought to her another slice, the insatiable unicorn chomping cheerfully on the lemon confection. The Princess had an amused smile; the purple mare was quickly turning into a roly-poly.
Celestia lightly patted her own enlarged paunch; despite its size, its ivory skin seemed to have regained a semblance of suppleness. Perhaps she had started assimilating her gargantuan meal, or it could be she was already growing accustomed to such excesses; in any case regaling her favorite had itched her for more sweets. The gormandizing goddess indulged herself with her share of sponge cake, slowly savoring a generous slice as she was feeding Twilight Sparkle the remains. The glutted Princess had to take her time to not get sick, but the sugary delicacy was worth the effort, as well as the unforgettable heaviness building in her distended gut. Only the chocolate torte was left, Celestia eying lustfully the glazed confection. She discreetly licked her lips in anticipation, thinking of the thick chocolate titillating her taste buds, each mouthful sliding down her throat to fill further her protuberant belly. Yet the effects of the spell vanished, the Sun Goddess could not ignore her responsabilities. As much as the Princess wanted to push her limits, her sister was not present to raise the Sun in her place; Celestia had to put a stop to her dissipated episode. She had a regretful sigh; yet judging her prodigious girth, the sated monarch had a pleased smile. She was imposing, her new figure matching her outstanding height.
Twilight Sparkle would have been dozing if not for that appetizing chocolate cake taunting her; she observed her mentor, afraid the tasty torte would escape her.
Celestia was rounding out, her growing curves contrasting with her traditional thinness; even more so on her voluptuous thighs and her august rump. But it could be only a prelude, judging the astounding size of the Princess' bloated gut. Yet considering their respective frame, Celestia's belly was not much in comparison of her own... and the goddess' appetite for sweets was not to be underestimated.
The pony's capricious stomach groaned, reclaiming its share. Amused, Celestia gently rubbed the purple mare's colossal gut.
"That's quite a tummy you have there Twilight, don't you think you pushed yourself hard enough?"
Twilight Sparkle had a disapproving look.
"Princess, I'm fine."
The mischievous goddess shook her head.
"I can't let your dedication put you at risk."
Celestia brought a slice of chocolate torte to her lips, taking a bit of the tantalizing confection. She had a disappointed sigh.
"I don't think I can finish this myself."
Twilight Sparkle had an impatient look; a chubby foreleg rested on the Princess' flanks.
"Princess, I know I can."
The Sun Goddess had a gentle smile, and the cake slice came close to the unicorn's lips. The porky mare opened wide her muzzle, quivering of excitement. Celestia pushed the whole slice in the pony offered mouth, devoured with jubilation by her protégée. Twilight Sparkle's tremendous belly gurgled of satisfaction, and the Princess affectionately fondled her favorite's massive gut. Two more slices made their way in the young mare's bloated stomach before her breathing became laborious; the oppressed unicorn had to lie on her side, freeing herself of her own crushing weight. Her fantastic belly crashed on the floor, her lardy paunch rippling as she was catching her breath. Noticing her mentor's worried expression, Twilight Sparkle had a reassuring smile.
"It's... nothing... Princess..."
The insatiable mare moved the torte closer to her, sinking her teeth in the dense chocolate. She gorged on the rich confection under Celestia's attentive eye, covering her muzzle with chocolate. Watching her, the perplexed goddess could not help thinking of an expecting sow feeding herself in her trough. Yet the Princess admitted her own excesses were rarely without their part of messiness.
The chocolate delicacy vanished in her bursting stomach, Twilight Sparkle had a contented sigh. The purple mare felt her own squishiness of a prudent hoof, intrigued. Her whole body was quickly swelling; her thighs and rump were growing soft and large, enough to support her new ample frame. The gaining pony was too stuffed to move, immobilized as a beached whale, yet her situation was unexpectedly satisfying. To her surprise, her own fat was making for a quite comfortable mattress. Celestia gently teased of the hoof her favorite's protruding gut.
"It seems you have quite enjoyed yourself after all."
Holding her gigantic belly, Twilight Sparkle licked of her lips the last remains of chocolate. The embarrassed pony had a self conscious smile.
"Princess, I think I ate more than you did."
Lightly poking at her own prominent paunch, Celestia had a gracious laugh.
"Yet I had enough Twilight."
And it was true the goddess herself was rounding out, her plumping curves giving her an affable charm. Reassured, Twilight Sparkle had a dreamy expression.
"Even after I ate so much, I still enjoyed every bite."
As she said that, the purple pony's belly grumbled softly. With an amused smile, Celestia brushed her bulging side against the young mare's overfed gut.
"Should I get you something else now?"
The bloated unicorn had an astounded look.
"Princess, I can't keep eating like that. We have to find a cure!"
Celestia had a thoughtful look.
"I wish I knew how the spell passed on you, a contagion could have disastrous consequences."
Twilight Sparkle prodded of the hoof her inflated paunch. A thick roll of fat was forming on her swollen gut; she had a flustered sigh.
"Spike is gonna be so worried. And if my friends could see me like this..."
The Princess kindly patted her favorite's growing belly.
"We have to make the best of it Twilight; didn't we have a pleasant time?"
The fattened mare was hesitant.
"Of course Princess, I just wish I wasn't getting that big!"
The fleshy goddess had an elusive smile.
"I am certain we will fix that in due time."
