Day One - Breaking them in

Author's Note

After looking at a myriad of art, I got inspired to do this little piece. Hope you enjoy.

Day One - Breaking them in

A slow moan of pain gasped from the lips of a long, slender creature, stirring pitifully in the cloying darkness. Cracking open one of her eyes, the pink orb peered into the blackness. From first looks, the walls appeared to be those of a cave, rounded and worn, distinct completely from that of a normal building. Adjusting to the gloom, she spied multiple lamps on the walls, oval in shape, casting a very dim green down the sickly green/grey walls. Following the contoured architecture down, her eyes met the surface of what appeared to be a great body of liquid. A distinct lack of wind caused the surface to remain static, even as long globs of the stuff leaked from the ceiling, depositing themselves with quiet plops. Thin fingers were curled against herself, aware of the cool, but humid air.

Tilting her head, she caught sight of her body, her fully exposed, naked body. A small, involuntary shiver ran down her back as her hands flew to cover her breasts. Panic starting to fill her body, she glanced to her side, barely picking up the sounds of quiet breathing. Laying there on the bank was a blue alicorn, just as naked as she was. Her flowing, ethereal hair was piled up around her head, acting like a pillow on the hard flooring. “Luna! Luna get up!” the mare hissed, reaching over with a white hand, giving her a nudge on the shoulder.

“Celly…just 5 more minutes…” Luna responded, rolling over, resulting in her banging her arm sharply on the floor, jolting her awake. In an instant her deep sapphire eyes shot open, peering around the room. “What in the name of Equestria?” she called out, eyes flicking back over to the white mare, her face creasing in worry. “What is going on sister?”

Celestia pushed herself upright, finding the strength to rise to her feet. “I have no idea, the last thing I remember doing was tucking myself in last night, finishing a small slice of cake. Now I haven’t got the foggiest idea where we are…” Reaching a hand towards the night princess, Luna graciously took it, rising to her full height. Now they were fully lucid, Celestia craned her head around, looking for an exit. What she noticed was a subtle sweet smell in the air. It smelt fresh and had a somewhat organic smell to it the mare couldn’t quite place. Scanning the walls, she was disappointed to see that they looked sealed, like the room had been built around them. Squinting in the darkness, she decided to light her horn.

Instantly, she felt an odd tingle in her horn, with no light appearing. Frowning, she tried again, only to be met with the same feeling. Reaching up, she placed her hands onto the long keratin spike, only for them to collide with something first. “My word, Celly, what in the world is that?” Luna’s voice called out; her eyes transfixed upon the strange device. Surrounding her horn, were 4 long black rods, with metallic bands ringing around them every so often. A number of dull green gems were embedded into slots on the rods, which pulsed slightly with light as Celestia attempted to light her horn once more. Looking back over to Luna’s own head, she noticed a similar looking artefact placed onto her head.

Grasping it with a hand, Celestia attempted to pull it off, only for it to remain in place, even after some painful sharp tugs. Just as Luna was starting to fiddle with her own, a long bubbling, tearing sound came from the wall behind them. In an instant, the sister whirled around, hands at their sides. Brighter, but still green light poured through the hole, which was obscured as multiple silhouettes blocked the passage. A low snickering, followed by a cackling rang out as a tall figure slowly made her way in.

She was dressed in what appeared to be a bodysuit and legging, made of overlapping layers of green petal like structures, it’s dull shine giving the appearance of leather. This was tightly wrapped around her onyx skin, with the tops of her shapely thighs to remain exposed. Her large bust was tightly wrapped up too, with the large orbs almost threatening to pop out at a moment’s notice. A nasty smirk was plastered onto her lips as she strutted forwards, flanked by several guards.

“My my… Look at you two, you do look pathetic, well, more so than usual.” At those words, the alicorns fell into a battle stance, raising their arms ready to fight her.

“Chrysalis! I should have known it was you!” Celestia growled out, watching as the guards filed in behind, covered in thick chitinous armour, before the wall closed again with a slick snap. They had their hands wrapped tightly around a mixture of weapons. One brutish looking individual brandished a warhammer, lightly drumming his fingers on the shaft. “Whatever you have planned, I won’t let you get away with it!” Her horn attempted to glow with energy once more, only for it to be syphoned off once more. The Queen’s mouth split in a terrible laugh, which was joined by her guards, as her own horn hummed to life. Sickly green energies dancing around the crooked spike, arcs of magically charged electric dissipating with a small whiff of ozone.

Instantly, the sisters suddenly felt a sharp pain in their heads, forcing them to their knees as they cried out. “Oh, such bravado will get you nowhere Celestia. You see, I admire how powerful your magic is. If I were to let you go, you or your sister could vaporise me where I stand. So, I did the one thing that would stop you… cut off your magic and turn it against you.” Reaching out with a long finger, she traced it down the metallic rod, watching as a small arc of magic leapt to her finger.

“You see, standard inhibitor rings would have just burnt out from the raw energies alicorns produce, so I had my best artificers make these ultimate nullifiers. Able to store the intense magic inside specially crafted and refined storage gems, then release them when needed, say… when a certain bad princess is being a little too hot headed.” Glancing over to her minions, they instantly surged forwards, grabbing the two mares, dragging them over to the lakeside with some difficulty as they tried to shake off their vice like grips. Now with their faces just over the water’s edge, Luna could clearly smell the sweet odor of the liquid.

“W…What is this?” Luna muttered, wincing slightly at the tight grip the guard had on her arm.

“That, is none of your concern, only that it is… a little experiment so to speak.” The two raised an eyebrow, Celestia’s face knotting in concern. “You will drink the liquid, and I will watch you do so.” Luna was about to resist, when the intense pain that the inhibitor brought flashed back through her mind. Gulping, she knew she had no choice in the matter. Slowly, the night princess leaned down, before submerging her mouth into the liquid. She nearly gagged when she took her first mouthful, not expecting it to be so viscous. It reminded her of jam or thin syrup, where she could barely gulp it down.

Bland was the best word to describe the taste. Bland with the same slight sweet flavour behind it. It wasn’t unpleasant, just uninteresting. As it slid down into her belly, she pulled her face out of it, with long ribbons of ooze still attached to the surface. Luna then felt the Queen’s hand forcefully push her back down again. “Did I say you were finished? You will be done when full to bursting with my special formula, so get sucking Princess!” Knuckling down, the pair drank in silence, the only sound being the gulping and occasional complaint of their stomachs as the foreign goop was forced in.

Surprisingly, as they drank down more, the better it started to taste. Going from the tasteless muck, soon an almost candy flavour blossomed, like that of an apple. Luna took another, even larger gulp, swelling her cheeks out like a chipmunk. “That’s it… keep going, gulp swallow, gulp swallow. There’s nothing too it…” Kneeling down, she reached out her hands, giving their distended bellies a rub, both sputtering from the pressure on their sensitive stretched skin.

Already, the heavy goo had stretched out their stomachs a fair bit. Their trim, flat middles pushing out into slight pot bellies from the sheer quantity of goop shoved into their guts. As they continued taking in mouthfuls, another effect was becoming apparent, though the two were too engrossed to notice. Before, they had to force down each throat rippling glob, but now they were picking up the pace with a little vigour. “Oh, I should mention, that special formula has a slightly addictive property… Not that you can stop now of course, you’ve already packed your alicorn bellies to the max with the stuff, flooding your brain with pleasure signals.” Giving the aforementioned guts a pat, she watched in fascination as they still wobbled and sloshed, despite how packed they were.

A moment later, the pair were dragged back from the edge, pushing them onto their backs with a dull thud and a slight strained blorp. The pair winced as they blinked, the slight glassy sheen dissipating as they came too, before another angry gurgle rose from their guts. Leaning against a nearby pillar, Chrysalis was tempted to let them suffer, but she had a job to do. Lighting her horn, she targeted the devices surrounding their horns. With a crackle, the gems pulsed angrily, coronas of excess energy spiralling off as the second function of the insidious contraptions worked. Both the sisters felt a tug of magic in their skulls, unnatural and unwilling, like a leech drawing blood.

With a cruel smile, she watched as their horns flared to life, the normal white and blue magic tainted by swirls of the sickly changeling magic. It swam through the aura, like pollution spreading through a crystal-clear lake. Even in their altered state of mind, the alicorns could feel how wrong this was, how their own magic signature was being violated by an outside force. Suddenly, the workings of a spell were formed, as Celestia watched her corrupted essence encircle her gut before she felt the pressure inside dissipate and shrink. Eyes widening, she watched as her breasts began to expand outwards, like a balloon at a fair. But unlike a balloon, she could feel the new heft being added to them, like they were filling with a liquid.

“Oh perfect, the formula is working just as planned!” The Queen crowed in excitement as Luna jumped from a D cup to an E cup in a few short moments. However, something else had caught the insectoid’s attention “It seems that it isn’t completely perfect though.” Luna let out a gasp as the sable hand encircled a new formed belly, currently puffed out onto her lap. Indeed, breasts were not the only thing that had grown. The once trim sisters now were bloated and podgy, as budding love handles encircled the tops of their rounded thighs. Upper arms swelled out, the beginning of bingo wings starting to touch their elbows. Their lean, shapely faces had rounded out, the ghost of a pair of jowls on the horizon for the pair.

“You… you monster… How dare you do this to us. Violating our bodies and disfiguring them!” Luna burst out, anger tingeing her widened cheeks red. Fists clenched, she took deep breaths as she glared over the changeling, who gave her a mock blown kiss, then pointed to the night princesses horn.

“I dare? Of course, I dare. You two are prisoners of the Changeling hive. You have no idea how long it took for me to set this in motion. The amount of deception I have been sowing. There will be no evidence I ever captured you two.” Sauntering over to Luna, she booped her swiftly on the nose, though it was more of a smack than a friendly gesture. “I. Own. You. Both. I own your bodies, your magic.” She turned around, heading to where the door should be. A moment later, it peeled back, allowing the procession of ‘lings to exit. With a small clatter of armour and weapons, they swiftly made their exit. Just as Chrysalis was about to leave, she pivoted on her heels. “And soon, I’ll own your mind too…sweet dreams.” With that the door slammed shut, leaving the room in near darkness.

For a moment, the two didn’t know what to say, just looking across at each other with saddened expressions. Celestia watched as a thin line of white liquid leaked from Luna’s right nipple, dibbling down onto her flabby tummy. Already, she could feel an unnatural wave of fatigue pass over her, as the accursed device began to work another involuntary spell. “That Harlot… I already feel like a fattened sow.” Luna whispered, nearly inaudible. “If only we fought harder…”

“I certainly hope she was bluffing about the planning. Fret not dear sister, I’m sure that Twilight and her friends are already looking for us. Hay… I’m sure everypony in Equestria is looking for us. Give it a few days, and we’ll be out, right as rain and ready to hit the gym.” Celestia smiled, half believing her own lie. The air of confidence surrounding the Changeling was near asphyxiating. She knew, deep down, that she was going to be here for a long while.

Another burst of fatigue caused her eyes to droop, flutily staving off sleep, until she collapsed, followed moments later by Luna. As they descended into dreamless slumbers, the only sounds were that of their light, airy snores filling the room. Only for it to be interrupted from a quiet, wet slap of a new load of goo ringing out as it was deposited into the pool.

Day Nineteen - Beginning production

Several weeks had passed since they had first arrived in their damp, humid chamber. Unfortunately for the pair, no help of any sort had arrived. At least, they assumed a few weeks had passed. With no natural light, it was extremely hard to judge the passage of time, aside from the visits from their captor. She had made it a personal point to go and visit the helpless alicorns, taunting and belittling them at every opportunity she had, sapping the pairs resolve.

She would stand there, as her guards hauled them to the lakeside, forcing their muzzles back into the gunk. Although, she needed to force them less and less to do so. Despite the fact they wanted to fight back at the tyrannical bug, they simply couldn’t find the will. Every gulp of that irresistibly sweet ooze would further pump their system full of the addictive chemicals. So much so that they would only need the slightest prodding to do so.

Such rampant levels of consumption had had rather unfortunate effects upon their bodies. They had positively ballooned in size as the fattening gunk was digested and turned into wobbling layers of flab. Slabs of juicy belly flab hung down to their knees, managing to cover their nudity. The blue and white flesh eagerly wobbled with every small motion they made. Legs and thighs had turned into tree trunk like columns of blubber, just about managing to hold their pendulous forms up. Accordion like rolls of back flab crowded their forms, drowning their once proud wings and sagging onto their tails. Said tails were additionally being consumed by the rising swell of their medicine ball like bottoms.

Their Cutie Marks had become horribly stretched out, reaching the size of a soccer ball as they curved around the swell of their cheeks. Their forearms had additionally been expanded out, bingo wings threatening to swallow their forearms as the excess adipose sagged over their elbows. On their faces, double chins were in full swing, as they budded under their rounded-out faces. Collars of neck fat encircled them like a neck pillow, providing a small cushion to rest on.

The largest change however had been the alicorns breasts. Whilst the formula fattened up the rest of their body, a disproportionate amount of growth had made their way to the utterly insane boobs. The only thing that prevented the sisters from falling over anytime they were forced to stand up was their sheer alicorn strength and the slight counterweight their rumps provided. Even so, they had to have assistance to get to their feet, most of their time was spent pinned by the intense weight of their forms. Gravity was certainly a cruel mistress, as it tugged at every hanging fold, rolls and slab of blubber, pulling them down. Every feeding they would balloon up every larger, milk and flab sloshing around heavily within. They were so big that Celestia had to crane her head over them to get a glimpse of whatever was in front of her.

Their thick, erect nipples were almost constantly leaking creamy milk down, pooling onto the floor. Fortunately, it had a slant to it, allowing the excess milk to drain down small grates, allowing their increasingly cramped sleeping/living area to remain at least slightly dry. Currently, the two were sleeping, slow snores ringing out, causing their bodies to jiggle and rock minutely even whilst they slept.

A familiar organic click rang out as the wall opened once more, revealing Chrysalis. Striding in, she contained a small giggle as she approached the sleeping, obese forms of the endowed alicorns. With an evil grin plastering her fanged mouth, she latched onto one of Luna’s nipples, groaning as her mouth was filled with a small blast of milk. The lunar mare groggily opened her eyes, before almost immediately screwing them up as her form was rocked with waves of pleasure. Sensitive nipples were teased and suckled upon, rivulets of the delicious alicorn milk dripping down her charcoal face as she mashed her face into the navy-blue breast meat.

“Ahhh…oooh…please…nnngh…stop…ahh…!” She moaned out, feeling those sharp fingers encircling her mammoth tits. A couple seconds later, a sharp gasp tore itself from Luna’s mouth, before a burst of fluid slicked the floor between her giant thighs. With one last suck, she drew back, before lighting her horn. Around her, wisps of pink energy floated through the air, radiating off Luna. With another burst of magic, the energy flowed into her open mouth, causing her stomach to pulse a dull pink.

“Oh yes…you do give of some potent waves of lust. I was practically drowning in love. How does it feel, to have no willpower and to just willingly feed your enemy like captured livestock? You are such a pathetic cow Luna.” Said mare gave no response, though a small quiver of her lip told the cruel changeling all she needed to know.

During the commotion, Celestia had opened her own eyes and watched on in despair as her own sister’s body was abused and violated. Just as she was about to shout at her, Chrysalis’s head span around with a grisly amount of articulation, complete with a sickening organic crunch, sending chills down the mare perpetually warm body. Strutting over to the sun princesses’ side, wrapped her hand around her Celestia’s flabby chin, before shutting her mouth with a quiet clack.

“Oh Celestia, Celestia, when will you just give in? Your body has been deformed into that of a fattened bovine, and your rampant addiction to my wonderful formula has warped your mind, filling it with distractions and turmoil.” An angry snort pushed its way out of her nose.

“Never. I will never give in to the likes of you, you perverted locust. As long as I live, and my ponies continue to search for me, I will never surrender myself to you.” A mock look of pity crossed the Queen’s face as she gave Celestia’s thick pink nipple a slight caress, Celestia’s fattened hand clenching into a fist.

“Pity. Such a shame that you won’t just lay down and throw in the towel.” She walked out towards the lake’s edge, her hands crossed behind her back. “No matter, I don’t care whether you submit or not. The feeding programme will continue on schedule to phase 2, if you like it or not.”

“Feeding programme?” Luna finally spoke, a look of confusion plastered to her rounded complexion. Not speaking, the changelings horn lit up once more. As baleful light filled the chamber, the sisters became aware of the sound of something dragging on the stone flooring or pushing its way through the treacle like fluid. Managing to look past her breasts, they both caught sight of multiple tubes snaking their way out from hidden alcoves in the walls. Like a lot of the things in the hive, they had a distinct organic look to them that set them apart from an ordinary rubber hose. They glistened like wet leather as their bulk skidded up to their sides, accompanied by another set breaching the surface of the pool.

“Yes, feeding programme. My greatest plan, to ensure my hive has a near constant food supply for all eternity. Surely, you must have wondered why I simply didn’t just imprison you inside cramped cells? Why have I spent a near month inflating your boobs into boulder sized mounds of milk?” Slowly, the pieces were clicking together in their minds, eyes widening at the sudden horror they were being involved in.

“Before I decided to capture you two, I decided to do some research about alicorn biology. True alicorn biology mind you, not just ascended ones like that insufferable Cadence or Twilight. No, pure breed is what I needed.” She paused, picking up one of the tubes in her hand, twirling it around like an impromptu lasso.

“Did you know that alicorn milk is one of the most nutritional fluids around? The host's innate, powerful magic seeps into her lactate, saturating it to the point that it is one of the most potent in all mammals. So, what better way to feed up the next generation of changelings then to nurture them on the best stuff in the land? Just think, your bodies literally being used to serve your enemy, every gallon of milk allowing a drone to build new cells to house our young. Every drop being used to strengthen an infiltrator for another perilous, but successful mission.”

Roughly grabbing Luna’s cheek, she forcibly turned her head to gaze into green blazing eyes, ignoring a tricking tear that splashed against her digits. “Your bodies will fuel the continued downfall of Equestria.” A flick of her horn, and the tubes slithered up the sister’s belly rolls before latching onto their nipples. The leathery green material clamping on as the second set from the pool pushed it way into their mouths, forcefully opening their locked lips. Already, Celestia could feel the sweet ooze leaking down her throat, her altered, befuddled mind telling her that she wanted more, more! She tried to fight the overwhelming temptation as pleasure signals fired off ten to the dozen through her brain.

Then, a sudden jolt from her breasts, followed by a regular, rhythmic sucking from the tube. A stuttering moan left her lips before she could stop herself, a blush spreading to her rounded tennis ball cheeks. Watching the tubing, she saw large pale bulges being drawn through the material, disappearing into the gap in the wall. The set locked around Luna’s breasts doing the same, sending litres at a time to flow off to some unknown part of the hive. More and more of the goo was filling her belly, continuing to sap her resolve as she tried to feel some emotion other than pleasure and lust. She wanted to be angry, angry at Chrysalis, angry at herself for not fighting their capture hard enough, angry at even her subjects for leaving them to this fate. Alas, any spark of negativity was washed away like pebbles in the ocean tide, naughty amorous thoughts permeating her brain instead.

Glancing at the devices pressed around the pairs horn, Chrysalis let the opaque aura surround the twisted spire, before triggering the storage gems to release power. “This’ll help keep you eating. That will constantly trigger the digestion spell anytime your bellies fill to the max, keeping you perpetually eating, never feeling full.” From the hoses lodged in the sister’s mouth, they couldn’t respond. Not when their minds were wracked with constant pulses of orgasmic lust and addiction. For a moment, the changeling monarch basked in the intoxicating waves of love pulsing off their bodies, gulping down another few mouthfuls of powerful energy.

With one last drawn out gulp, she licked her lips, satisfied from her meal. “Ahh, you two make excellent love batteries…I may have to find a better way to siphon off all your delectable energy at some point.” About facing, she strode off to the door hearing Luna’s inhibitor lighting up, followed by a low groaning blorp as her body expanded outwards just slightly. Satisfied with the stellar work, she stepped out into the much cooler corridor, the door fusing into a wall. Deep in her thoughts, continuing to scheme, she failed to notice that her outfit felt just a bit tighter, and that her small parts of her form seemed to jiggle ever so slightly as she walked.

Day Fifty Three - Blobs and Breasts

Celestia awoke once more, her pink, glassy eyes flicking around the gloom. The same constant dull green glow constantly tinged her white body the same dark green tincture. Coming to her senses, she attempted to stretch her arms. As was typical, nothing happened. She couldn’t see her arms, as an impressive tire of flab encircled her neck, preventing it from turning. If she could look past, she would have seen the appendage hopelessly sunken into her absurdly wide forearm, just as that had sunken into even larger bingo wings.

Not that she could really process these thoughts to any reasonable degree. Her mind was pumped with a potent cocktail of chemicals that prevented her from thinking straight for even a moment. Both from her own arousal, and from the feeding, which had gone one for… some amount of time. She wasn’t sure. It had to have been at least a month or so, or a few weeks? The constant light and irregular sleep patterns had messed with her perception of time. All the while she wallowed in her enormity.

Describing the Alicorn of the Sun and Moon as anything but roiling piles of flesh was folly. Not that anypony had seen them mind you, that privilege was saved for the Queen and the occasional guards who ran maintenance on the equipment. They had to be the size of buildings, easily. Wide mattress-like rolls sagged down from every part of their immense guts, piling against the floor, oozing across the stone. They had grown so large that part of them had to rest in the goo itself, submerging a good portion of their stomachs into the treacle like slime. The crevasses in their rolls were so deep that you could lose entire ponies in them, never to see the light of day.

This was compounded by their butts and thighs. Each were larger than heavy goods wagons, significantly wider too. A myriad of creases cross crossed them, distorting the billboard sized cutie marks plastered across them. The sheer level of deformation of the symbols made it look like they had melted. If you were to look closely, a slight tuft of their tails poked up, looking disproportionately small compared to the mammoth mounds. Her feet had suffered the same fate as her hands, swallowed by calf blubber, which in turn was swallowed by thigh fat, rendering the joint immobile, it’s only function to accumulate more useless lard.

Their wings, majestic and beautifully preened and cleaned, were nowhere to be seen. This was thanks to the great bed like slabs of back fat, drowning them and trapping them in between the giant folds. The tips of one of Luna’s primaries could be seen just poking out of a roll, never to be used again. The only thing which they could do was to continually gulp down more and more, their throat muscles the only thing not atrophied. A mattress-like ring of neck blubber allowed Luna’s beach ball sized cheeks to rest on them, along with the nearly uncountable amount of chins.

However despite their impossibly obese forms, they couldn’t hold a candle to the pair of breasts they had. The best way to describe them would be two ovoid like orbs, each around the same size as the mares immobile bodies. Thick with fat and milk, the nipples were the size of the sisters' entire bodies before their imprisonment. Although you couldn’t see them, with massive tubes firmly latched onto the teats. The near constant pumping sent gallons upon gallons of creamy nutritional milk deep into the hive, more and more to feed the numerous ranks of the changeling hoard. The two of them had become dull to the sensation of being milked. By now, it was a constant process, just like breathing, swallowing or on rare occasions, crying.

Celestia felt her horn activate, her involuntary casting wrapping around the monumentally large swell of her belly. Her overfilled gut groaned for a moment, before the mass of fattening ooze was digested. A low, content sound glorp sounded out, the noise reverberating off the cavernous walls. Moments later, she felt a greasy tingling in her skin as pounds accumulated across her form. Her breasts swelled ever larger, taking up more and more space in the cramped chamber, waves of goo lapping up against them as fluid was displaced. She could feel more of her body sagging onto Luna, their bodies squashed together from the lack of room.

A moment later, a low yawn rang out. The distinct, twin tones of her voice identifying her clear as day. None other than Chrysalis herself was currently laying on one of Luna’s back rolls. Her body was partially sunk into the soft flesh, a body which had become distinctly wider compared to her sleek form of old.

An apron like gut sagged close to the tops of her knees, the bands of green marred by blobby rolls. These circled around her, creating juicy love handles that connected to her flabby back. Pillow like folds stacked atop one another as they flopped onto her wide ass. With a butt comparable to a pair of medicine balls, those cheeks swelled wide with lard, creating heavy onyx globes that compounded upon a myriad of curves. Tree trunk-like legs lead down to her chunky calves and thick thighs. Fleshy, wobbly arms were ended with thickened fingers, which were currently brushing a strand of blue mane out her rounded podgy face.

Her breasts were on full display, though not disproportionately large like the Alicorns had developed. Soccer ball sized, jiggling with ease as they sloshed around, filled with delicious changeling nectar. Currently, they were smooshed against the same slab of mattress thick blubber she was currently rousing herself from. Her predatory eyes flicking open, they adjusted to the low light in an instant. With considerable effort, she hoisted herself to her feet, feeling herself sinking into the pliant body of her old enemies. It was hilarious to her. Those once slim, intimidating and powerful creatures had become nought but a source of food for the hive, and an impromptu waterbed of princess flab to sleep on.

“Mmmm...good morning everypony…” she called out. “I had a wonderful sleep Luna, I must say. Ironic that the princess of the night makes a good sleeping aid.” No response came back. Though, she hadn’t expected one. Their bloated lips were jammed firmly open with the tubes, making any meaningful dialogue impossible. She didn’t mind though, it was certainly better than them constantly telling how they would be ‘rescued’ and that they’ll ‘never give in’. She fought back another round of mocking laughter, stifling herself as she plodded over the vast contours of Luna, moving over to the sun princess instead.

With a wobbling, exaggerated step she clambered onto Celestia’s back instead. Using her love handles as actual handles, she hauled her obese form higher and higher up until she reached the swell of face fat. With a smile, she plopped herself down, laying back on Celestia's neck roll. Her head was resting on the cushion sized slab of cheek fat. “Hello Celly, how are you feeling, hmm?” Reaching across, she gave the other water balloon like cheeks a small pinch, Celestia’s glassy eyes wincing slightly. A moment later, a small content moan rasped out from around the tube.

“Good? I hope so. After all, your mind is ever so quiet as of late. No pesky thoughts of escape, rescue or even the horrifying reality that you are the fattest mare in the world, doomed to become even fatter. How does it feel to turn from a regal princess into a common cow, breasts bigger than barns?” No response as usual. She briefly considered flushing out all the chemicals addling her brain, to see how long it would take to break her again. Alas, that was effort, and she had developed a distinctly sedentary lifestyle.

They didn’t need to go out and hunt prey, risk themselves fighting terrible monsters or all manner of harsh conditions beyond the deep tunnels of stone and resin. Why risk anything when they had literal underground lakes of food? “You know, I still hate you after all this time. Not because of your power or stature. No, I’m past that.”

“I hate that you two destroyed my beautiful figure with your love and milk.” A content smile spread across her face. “But, conversely, I also love you for that too. My hive will thrive forever, even if I have to put on a few hundred pounds for its safety.” Casting her magic, Chrysalis basked in the thick waves of love that had saturated the room. She forced more and more of the potent energy down her throat, topping her flabby gut off. Despite how much she disliked her overblown figure, the availability of so much food in the air was too much temptation to pass up. Belching contently, she splayed out, cooing lightly as she sank further into the plush fold.

Moments later, she was interrupted by a gurgling groan. Luna had just finished her next load of gel, her continued blimping and ballooning pushing against Celestia, which by extension caused her love handles to press against the walls of the chamber. As her immense globes of ass fat squished against the wall, a small pang of concern flitted through the queen's brain. Any more growth and her blobby milk machines would tear through into the main hive. But, then again, she could easily make more room for her prized cows.

Closing her eyes, the changeling queen let the sounds of unrestrained gluttony fill her ears, as her personal pitiful pony princesses let their figures continue to degrade, uncaring as dozens of pounds of fresh, pilant flab accumulated across their grossly bloated bodies. Swelling ever larger, the dim lamps on the wall becoming submerged under the fleshy bulk, making the cramped chamber even darker.
