Celestial Body Swelling

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.

As Celestia watched the room blacken, lights snuffing out, one last pleasured moan rang out from the impossibly large creature, those pink orbs shutting, cocooned in the fleshy embrace of herself and her sister as she drifted back off into a dreamless sleep.
