Celestial Body Swelling

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.
