Ferrous, the Cesar of a vast empire in the northern Equestrian wastes, enjoys a visit to his favorite place on Earth.

Ferrous has ruled over his empire for a number of years now, and has watched it grow into the brightest example of civilization since the fall of the megaspells over two hundred years ago. All of his success has been built off the back of a powerful, seemingly impossible asset: an army of clone soldiers. Thousands of identical soldiers flooded across the northern reaches of the wasteland, asserting their dominance and bringing some semblance of peace to the tumultuous land.

Though he now sits at the top of his world, Ferrous will never forget what made this all possible, what made his dreams come to life. The individuals who continue to work to allow him to achieve his goals.
In fact, it's just about time to pay them another visit.

Chapter: The First One

It wasn’t that long of a walk, to be honest, and it’s not like he was out of shape or anything. No, it should’ve been perfectly reasonable, the only problem was all the damn stairs. Six flights, seven, and then finally the stallion topped the eighth flight, taking a moment on the landing to lean against the rail and catch his breath. Ferrous was a fairly mild mannered fellow, but sweet Faust did he hate stairs. It didn’t help that he had never even been in a building with more than two floors growing up, and now that he was here, he had to go up and down these infernal things an ungodly number of times every single day. For right now, however, the view from the top balcony of his Curia Julia was more than worth it.

Ferrous slowly strode out onto the hanging terrace, a soft smile growing over his features. The capital was beautiful this time of year, the trees lining the streets an amalgam of autumn reds and yellows with the last vestiges of their lush summer greens. An early morning haze muted the sky as the rising sunlight burned through the mist, turning the whole world a comfortably soft orange. A small breeze ruffled the stallion’s bangs, bringing with it the wonderful aromas of baking breads and grilling fish as the vendors in the bazaar below prepared for a day of business. He could feel the slightest hint of a chill in the dawn air, a reminder than in only a few weeks the cold winds of the north would creep south and fall would grip them tightly, bringing with it snow and hard times for everybody. But for now, the temperature was damn near perfect, and living was easy.

Ferrus leaned against the decorative banner, watching as his ponies walked about near ninety feet below, looking like thousands of marching ants as they went about their lives. If he had his druthers, Ferrous would spend his entire day up here, watching out over his city, relaxing in the cool, fresh air. But alas, he had duties too, and the representatives wouldn’t be happy if he was late to court. Sighing, The stallion propped himself back upright and once again walked down the accursed stairs, though going down was always better than going up. Stopping into to his personal quarters, he found his way into the bathroom and walked up to face the full body mirror, inspecting his form.

Ferrous was a stallion of average build and height, standing no higher than six feet. He exercised when he could, and that was enough to keep slim and toned, but by no means was he excessively muscular. His brown fur was somewhat thicker than average, a trait he associated with having been born in the cold northern reaches of the Equestrian Wastes. A feathery black mane ran down to his shoulders, decorative beads of obsidian and turquoise having been braided into a strand hanging down the left side of his face, denoting his status as the Cesar of his empire. He ran his fingers through the fluff growing under his chin, wishing he had more time to shave.

Turning away from the mirror, Ferrous decided he would take a quick bath before having breakfast, something he wasn’t able to do as much as he would like, much to the chagrin of his maids. Turning on the faucet, he carefully disrobed as the tub filled with warm water, making sure not to dent the ridiculously expensive regalia. Solid gold gauntlets, a sash woven with rubies and mother of pearl, and a crown embedded with diamonds and engraved with heroic scenes of battle. To be honest, he felt it was all a bit excessive, but the representatives insisted it instilled a sense of confidence in his citizens, that their leader was strong and noble. Bunch of bs in his opinion, but it wasn’t worth fighting. As he removed his leather trousers, he exposed his cutie marks, a simple image of a lump of iron ore with a pickaxe plastered to each of his slim hips.

Once the bath was filled satisfactorily, Ferrous slowly slipped below the water, his tight muscles immediately relaxing. As hard as he tried to expedite the process, he just couldn’t bring himself to start washing, completely entranced by the heavenly warmth. Maybe they could wait for just a bit.

For over two hundred years after the fall of the megaspells, the Northeast stretches of Equestria remained largely untamed and unorganized. The largest settlements were coastal fishing villages with perhaps a dozen ramshackle buildings, and maybe fifty ponies living in them. Any further inland and the best semblance of civilization you might come across would be a small family farm, or a trading outpost. The biggest populations in these harsh lands were raiders, supermutants, and the irradiated animals that called this barren wilderness home.

And then, one day, a shining light of hope burst into being, illuminating the shadows that had swallowed the land for hundreds of years. An army appeared, enormous stallions with matching armor and armed to the teeth, and began to fight against the forces that had oppressed and stifled growth in the region. Nopony knew where they came from, or why they appeared to all be completely identical, with stark white fur, bright blue eyes, golden manes and no cutie marks to speak of. And really, nopony cared. All they needed to know was that somepony, anypony, was willing to help them. Soon, a brown, black haired earth pony, calling himself the General of this clone army, began to travel from farm to farm, asking to make a deal. Donate food to the cause, and be personally protected against future attack. The alliance spread wherever they went, families practically tripping over themselves to join and ensure their safety. As the army grew and the threat of attack diminished, more and more ponies began to migrate north, eager to make a life for themselves under the protection of the burly soldiers.

As the population grew, towns were built, which soon became villages. Small, subsistence farms became vast plantations, turning much of the irradiated waste into lush, fertile countryside. Amongst the villages, five cities were constructed, spaced out evenly across the territory. The surrounding villages and towns were incorporated into districts, with each city acting as the central government of each district, as well as giving each district its name.

To the east, there were two coastal districts that provided seafood for the rest of the empire. Piscariam Boreus, in the North, braved ice flows all year long that drifted down from the Frozen Barrier, a place where the sea ice never melted, and the harsh mountains kept even the bravest explorers from finding what lay behind them. Ancient stories tell of a gleaming empire nestled in the cold wastes, but the truth has been lost to time. While Piscariam Boreus specialized in large coldwater fish such as tuna and cod, the warmer waters off of Piscariam Australis brought in a plethora of shellfish, smaller fish like haddock and sardines, and even kelp. To the west was the enormous district of Villa Primus that stretched the entire length of the empire, top to bottom. Hay, carrots, razorgrain, corn, and more were grown in soil made fertile through a long and arduous effort of mages and farmers alike to purge the regolith of persisting thaumaturgic radiation. In the Southern reaches of the district, mutfruit fields, tato vineyards, and tarberry bogs provided the empire with the freshest fruits in the wasteland.

In the central north lay the largely unorganized district of Vocivus. Stark, rocky hills, arid heaths, and harsh weather had kept progress slow here, and the number of citizens living here were small. Vocivus was the smallest of the five cities. The empty tracts had allowed small groups of both raiders and supermutants to survive in areas of this district, though the expeditionary corps ran multiple hunting parties through known hotspots each day, whittling down their numbers.

And in the central south lay the capital district of Praetorius. By far the most populated district, ponies from all walks of life came to the capital to try and make something of themselves. Merchants, vendors and traders, bankers, teachers, there was a job for anypony willing to work. The capital city was a shining beacon of civilization, and in its center was the Palace, the Curia Julia, the seat of government for the empire. As well as acting as the home of the Cesar, the Curia was where five representatives from each district went to vote on laws, assign and distribute resources, and in general decide the direction of the nation. That such order, organization, and overall, peace could exist in a place as dark and violent as the Equestrian Wasteland was remarkable. And Ferrous could never have accomplished it without the help of a very special friend.

Ferrous watched through the window of his chariot as the countryside slowly rolled by. His head would bounce with every bump in the cobble road, annoying him to no end. Heaving a sigh, the stallion calmed his beligured mind, reminding himself that there was only one checkpoint to go before they reached their destination. Reaching his head out of the window, Ferrous looked forward, towards the pair of enormous, brawny clones pulling the cart. “How ya holding up?” he called to them.

“Just fine, sir,” the closest one replied. They were never much for conversation, but that didn’t keep Ferrous from checking up on them from time to time, he did care for them after all. They were currently heading south, and were finally nearing the border of the empire. They had been traveling for nearly five days straight, and Ferrous was itching to get to his destination.

After another three hours of bumpy riding, it had finally come into view. A vast complex of metal and concrete, hexagonal in shape, with each side stretching hundreds of meters across. Each of the three floors were lined with small windows, and the roof was segmented into defensive battlements, auto turrets and big, mean looking cannons pointing out over the flat, dusty landscape.

The entourage approached the military checkpoint situated about 300 meters from the entrance to the complex, a trio of identical stallions standing guard in front of a large gate. To either side of the gate, and electrified fence stretched as far as Ferrous cared to see. After a quick exchange of papers, the chariot was pulled through the guard station and began its final approach. This was it, the Seminarium. The place where his look-alike soldiers were made.

Upon entering, Ferrous immediately made for the westernmost section of the building, not needing any guide or escort. He knew this place like the back of his hand, he did orchestrate its construction after all. It was separated into four sections: living quarters to the west, mess hall to the south, a large open air training yard in the center of the complex, and the classrooms to the east, with the northern section being reserved for administrative offices. As Ferrous walked through the large hallways, he passed multiple troops of young clones of varying ages, each lead by an adult drill sergeant. He continued on until he reached the living quarters, making his way into the general recreation room. He pushed open the double doors and stopped, smiling at the sight waiting for him, doing nothing to try and hide the tent slowly growing under the leather coverings of his trousers.

Before him was a large, open plan room filled with toys and activities suited to young colts, too young to begin training. Colored blocks, wooden guns, foam swords, and more were being played with by hundreds of colts as they ran around and enjoyed themselves. But that wasn’t what was making Ferrous excited. No, what was getting him hot and bothered was the dozens of mares that also populated the room, each one minding her own group of colts.

Due to the shear number of clones that were being produced every year, Ferrous had found himself in a dire logistics problem. Despite their accelerated growth, with development from infant to a maturity level about equivalent to 25 years of age, after which they slow to the normal rate of a pony, taking about a year, there were too many being produced for him to take care of by himself. Not long after his empire began to take shape, Ferrous developed a solution for this particular problem. He had put together a team of ponies, mostly newly accepted citizens with a high level of education, to create a kind of secret service. Agents would go about seemingly normal lives, while simultaneously being on the lookout for young mares that displayed attributes, both physical qualities and mental disposition, that would make them the best caregivers he could get. These young mares would be lead out away from their villages, usually with an invite to work at the capital, and while en route they would be captured, brought in to a secret government facility for “capitulation training”, and then be exported to the Seminarium. As bad as it sounds, it usually wouldn’t take too much convincing. In fact, once it was explained to them what they were expected to do, as well as the benefits that they would be entitled too, many mares accepted the position willingly.

Once they arrived at the complex, these mares were developed into proper caretakers. As well as formal training, their bodies had to be improved so as to be able to provide for the colts under their supervision. To accomplish this, in addition to an extravagant and all-you-can-eat diet, part of the incentives to keep the mares happy, they were required to maintain a consistent intake of milk from Subject-01, known colloquially amongst themselves as “ambrosia”. This milk was what allowed the entire operation to take place. When consumed by the clones, it was responsible for the intense age acceleration they experienced. The only problem was that, as production of clones increased, the source of this strange milk began to struggle to create enough to satisfy the needs of the facility.

This was where the caretakers came in. As they drank, it changed them. Their bodies began to hold on to calories to an extent that Ferrous’ scientists had only seen once before, causing them to gain large amounts of weight extraordinary quickly. It also stimulated their mammary glands, causing them to produce bountiful quantities of milk themselves. And not only did they make enough milk to feed the hordes of new clones, the milk they produced had the exact same effects as the ambrosia they were fed.

The result of all of this was what Ferrous was ogling at this this moment: a room full of obese mares, ranging from “extremely fat”, to “how the hell can you even move?”, all with bean bag chair sized breasts resting atop their big, flabby bellies. Despiste their size, all of the mare’s chests were round and full, and barely sagged at all, their fullness keeping their shape and causing them to slosh with every movement. Most were occupied with a group of the little boys, trying to keep them from hurting themselves as they played. Almost all of them had a colt suckling at each tit, greedily gulping down the fresh milk they needed to develop.

Ferrous greeted the mares as he walked through the room, giving a wave and a quick hello to anypony who would acknowledge him. The newest additions would always keep their heads down and pretend not to see him, still too shy to even look at him. It was okay, though. He certainly wasn’t offended, and they would get used to him over time, they always did. He continued on his course until he came across a very familiar figure lumbering away from him, making her way around the groups of colts.

Most of what he could see was simply a gray furred ass rolling and creasing with every step as the mare waddled toward the back of the room. Now, fat asses aren’t a distinguishing trait in the Seminarium. Every mare there would easily outclass such a description. This one, however, put all the others to shame. The shear size of this mare’s butt left Ferrous absolutely enamored, her rump swelling outward to create a massive shelf swinging and bouncing behind her. Her hips flared out so as to make her every bit as wide as she was tall, while her cutie marks, what looked like a collection of small pebbles, were distorted as they stretched across their massive canvases. Each thigh was far bigger than any tree trunk Ferrous had seen, eternally squashed together and rubbing against one another as she shuffled along. The fat on her legs continued down to her calves, encasing her legs in a sheath of lard with only her modestly sized feet poking out. The top swell of her ass pushed into the fat halfway up her back, obscuring most of her torso from Ferrous’ view, each enormous cheek containing twice as much mass as the entirety of Ferrous himself. Yes, he knew this figure very well. She was one of the very first caretakers, and by far his favorite.

He sneakily moved up behind her, making sure not to make too much noise on the cracked linoleum flooring. As he slowly followed her, Ferrous took a moment to just watched her rump move, trembling violently with every step the huge mare took. Her light gray coat shined brilliantly in the bright lights, making her big naked body practically glow. Past a certain point, all the mares in the Seminarium decided to go naked full time. It simply wasn’t worth getting new clothing when they knew they were only going to tear it to shreds in couple weeks anyway. And this mare, a unicorn named Rockslide, had reached that point years ago.

Getting a devilish idea, Ferrous wound his open hand back, and with as much force as he could muster, drove it down into the cheek closest to him. The impact crater that formed sunk nearly half a foot into the soft, yielding flesh, sending ripples across the sea of fat that was her butt, the shock waves jiggling the titanic cheeks like gelatin. The loud slap reverberated through the room like a gunshot, silencing the horde of children and drawing all eyes on the pair. After a moment, however, everypony went back to what they were doing and the incomprehensible drone of excited squealing picked back up.

“Alright,” the big mare said, drawing Ferrous’ attention away from the mountainous rump and towards the back of her head, “whose the wiseguy?” The mare said in lighthearted tone as she began the process of turning her humongous body around. The amount of fat on her legs forced her to take tiny steps, lest she risk toppling over in a heap of flab. As she slowly turned around, Ferrous got a great view of what her butt had been hiding from him. The mare’s belly was incredibly big, an apron of fat hanging just above her knees, keeping her decent by completely covering her genitals. Her belly button was cavernous, and her arms were swollen into near uselessness, resting on her pillowy belly as they were too heavy for her to use for long. Once she had turned enough so as to see who it was that had slapped her ass into next week, Rockslide’s face immediately brightened, her chubby cheeks creasing with her smile.

“Ferrous!” the mare nearly shrieked, clearly excited to see the earth stallion. In a moment, the mass of her belly lurched forward as she reached up and grabbed his head, pulling him into a bone crushing hug. His face was smothered by her soft chest, while her thick arms felt like comfy blankets across the back of his head. Despite barely being able to breath, Ferrous did his best to hug her back, wrapping his arms around what he could of her belly, feeling them disappear into the flab.

“Oh, it’s so good to see you!” she said as she released him, finally allowing him to breath again as she beamed at him. “I’ve missed you so much!”

“I’ve missed you too, Rocky,” Ferrous replied with a smile of his own, still panting slightly. He leaned back in and gave each of the obese mare’s cheeks a quick kiss, causing her to flush red with embarrassment. As he leaned back, he noticed something about her that just didn’t seem right. After only a moment or two, the puzzle pieces fell together and he realized what was wrong.

“Your boobs!” Ferrous shouted without warning, once again drawing the attention of some of the closer mare’s around them. “What happened?”

As well as being the fattest, Rockslide normally had the biggest bust of all 100+ caretakers. But today, her boobs were relatively tiny! Instead of a pair of giant milk bags hanging down just as far as her belly, nipples nearly dripping from being full to bursting with milk, Rockslide was only sporting knockers about the size of beach balls. To be fair, boobs that big would be nearly unmanageable for a normal pony. But for this hippo of a mare, they seemed totally insignificant.

Upon him mentioning them, Rockslide’s already red cheeks darkened further, and she did her best to hide her face in the collar of fat that wrapped around her neck.

“Haven’t you been drinking like you’re supposed to?” Ferrous asked with concern, pointing to the metal canteen hanging from her wide hip. Like all the other mares, Rockslide kept a canteen of ambrosia with her, secured to her hip by a thin fabric belt wrapped around her waist, that she was required to finish by the end of each day. This was supposed to keep her tits full of milk for the colts, but obviously she had been completely drained.

Rockslide looked back up at him sheepishly, trying her best to force herself to make eye contact. “Can, um, can we talk about it privately? Please?” she nearly pleaded with him.

“Of course! Of course! There’s nothing wrong, is there?” he asked worriedly.

“Well...” the obese mare said before stopping herself, “I’ll tell you once we get to my room.”

With that, the pair slowly made their way in the direction she had originally been heading in, her fat body wobbling with every lumbering waddle. After a few minutes they finally reached the entrance to her room. Rockslide opened the door and pushed her belly through, its sides scraping and molding to the shape of the doorway. As she reached her butt, however, she was stopped dead in her tracks. The width of her enormous ass was more than a match for the extra wide door, her big cheeks jiggling as she struggle to work them through, her cutie marks distorting even more than they already had.

“Hold on, let me help,” Ferrous said as he approach the stuck unicorn. At first he tried to wrap his arms around the entirety of Rockslide’s butt and squeeze it through. He quickly realized, however, that he couldn’t reach anywhere near all of it at one. Rockslide let out a quiet moan as he fondled her sensitive flesh, trying not to focus on his strong hands roaming over her humongous rear. Ferrous then started to squish and push each cheek through the door separately, alternating between them whenever he made a little progress. After a while of going back and forth, he had finally gotten her nearly all the way there. All she needed was one last push, and she’d be through.

“Alright, Rocky, you might want to hold on to something,” the stallion said as he began to back up.

“Wait, what? Why?” she asked, her voice betraying her concern. She didn’t receive an answer, however, as Ferrous had already began his charge. Lowering his shoulder, the earthy brown stallion rammed into the soft wall of fat has hard as he could. In an instant, his world had gone black as all of his senses seemed to have been shut off. In reality, his entire upper body had been swallowed by Rockslide’s rump. For a moment, Ferrous simply enjoyed the sensation of being smothered by soft, warm ass fat. Then, a lurch sent his head spinning, the feeling of falling without seeing causing a small amount of vertigo. He simply laid there for a few moments, comfortable in the warm embrace. Then, pushing his hands down even further into the seemingly endless rump, he slowly pushed himself up, his head coming up and back into the light. The sight that greeted him caused a sharp laugh that he just couldn’t suppress.

Rockslide lay flat on her belly, head tilted down as though she were balancing on a yoga ball. Her butt, as well as Ferrous himself, was pointed towards the ceiling, with her pillar-like legs dangling off the ground. Rockslide’s muzzle was buried in her cleavage, her chubby cheeks squishing out against the fleshy orbs. Still chuckling, Ferrous crawled over the top of his friend, though it felt more like swimming through the soft fat, making the rest of his way through the door and hopping off once inside the room. He knelt in front of her head, doing his best to hide his amused smile.

“You uh, you alright?” he asked.

Rockslide lifted her head up slightly and looked at him, giving him an amused smile of her own. “Yeah, I’m alright. I don’t know if you’ve noticed, but I’ve got a lot of padding.”

Ferrous chuckled again, relieved that she wasn’t mad at him. Standing back up, he reached down and took ahold of her pudgy hand, gripping onto her sausage like fingers as she reciprocated. “You ready?” he asked the beached mare.

“Yup,” she replied simply, shooting him an impish smile, “are you?”

“Well, I certainly hope so,” the stallion answered as confidently as he could. He really wasn’t sure if he could lift the behemoth mare onto her feet, but he was absolutely going to try.

“Alright,” he said, straightening his back while bracing his legs,”one, two, three!” Ferrous pulled up on Rockslide’s hand just as hard as he could, while at the same time the obese mare pushed down with her other hand, adding all the extra force she was able to. And they needed every last bit of it.

At first it went fairly well, her head and boobs coming up off the floor with relative ease. Once they reached her belly is where they began to have problems. The solid mass of heavy lard sat like a doughy bolder on the floor, unwilling to be moved. Ferrous visibly strained, pulling with every ounce of strength he had. And very slowly, Rockslide began to shift upright. Eventually, the pair had managed to get her past a tipping point, the weight of her colossal butt pulling her the rest of the way into a seated position, landing with a loud thump. Once again Rockslide’s ass pressed against the open door, moolding and creasing against it, though this time from inside the room. Taking a moment to catch his breath, Ferrous leaned against the wall, panting as he glanced over to his rotund friend. Her legs were sprawled out in from of her, her incredibly fat thighs still squishing together all the way to her knees. Her thick paunch pooled on top of the crease between her round legs. Rockslide herself looked back at the brown stallion expectantly.

“Well, don’t stop now,” she said as she stuck both her hands up, gesturing him to grab them, ”the jobs only half done!”

Sighing, Ferrous trudged back over and once again gripped her outstretched digits. With a heave, he threw himself backwards, trying to use his own weight to supplement his pulling. As heavy as her belly was, her largest feature by far was nearly twice as big. Nevertheless, Rockslide slowly lifted off her rear, the job getting easier as her legs straightened, allowing her to use them in the struggle. Finally, she steadied herself on her feet, careful not to immediately trip and end up right back on the floor.

Ferrous, now completely out of breath, leaned against her, his forehead buried in the collar of fat around her neck, as he panted. Seeing her winded friend, Rockslide gave a short, sharp laugh.

“Ha! Now you know how I feel trying to get out of bed every morning!” Despite her teasing, she was still grateful, as she wrapped a pillowy arm around him and gave him a light squeeze into her doughy side. “Thanks, though,” she said much more softly.

“Heh, no problem,” Ferrous replied, putting his own arm around her shoulders and giving a squeeze of his own. Pulling out of the hug, Ferrous stood directly in front of the hefty mare, refocusing on the reason they were there in the first place.

“Now,” he said, reaching over the top of her gut and grabbing onto one of her boobs, rolling the beach ball sized orb in his hand and looking at her accusingly, “why are these so small? You know the rules, how are you gonna feed your kids? Have they already missed a meal?”

“Alright, first of all,” she began, making no effort to free her tit from his grasp, “I literally just put them down for their nap, and I fed them all as I did that. So no, none of them have missed any meals.”

“So why haven’t you, ya know, ‘recharged’?” Ferrous interrupted, pointing to her hip where the bottle of milk still hung. “I can tell your canteen is still full, so what gives?”

Rockslide looked away from her friend as she crossed her arms underneath her bust, resting her hands on top of her belly as she twiddled her thumbs. “W-well, it’s not like I don’t want to. It’s just that, well,” she sighed as her arms fell back to her sides, “I can’t...I can’t reach it.”

Ferrous just looked at her, confused. “Uh, I’m sorry?”

“You heard me,” she replied with an annoyed glare, “I had Strawberry Strudel fill it up this morning, and now I can’t reach it, see?” Ferrous looked down as she demonstrated. Indeed, her fat hips had swelled so far outwards that she simply couldn’t quite reach where the canteen dangled, her hand just patting the outer edge of her cutie mark. After a moment of staring, Ferrous burst out into an uncontrollable belly laugh, doubling over in his mirth.

“Yeah, yeah,” Rockslide said, annoyed, “laugh it up. I’m so fat I can’t even get a drink, I get it. I look ridiculous, I know.”

Quickly calming down from his moment of joy, Ferrous cupped one of her pudgy cheeks with a hand, getting her attention once again. He looked into her shiny golden eyes, a compassionate expression and a soft smile adorning his features.

“Actually,” he said quietly, ”I think it’s pretty fuckin’ hot.”

Rockslide rose an eyebrow at this, putting on an amused smirk. She had certainly expected something a little more eloquent from her Cesar, but hey, she’d take it.

“Oh yeah?” she replied, her eyebrow still raised. “Why don’t you put your penis where your mouth is and prove?” As soon as the words had left her, the mare’s face fell completely flat, both eyes now wide in slight shock. “Uh, that sounded better in my head.”

Ferrous laughed despite the awkward comment, reaching around and again slapping her gargantuan ass, setting it off into another fit of quaking and shaking. “Sorry Rocky, but my schedule’s too tight for today, maybe next time,” he said with a wink.

“Oh, fine,” she said, feigning disappointment, though part of her wondered how much of it was fake, and how much was genuine sadness.

“Although, that does bring up the question, what are you up to now?”

“Dude, really?” she said, looking up at him with an unconvincing smile. “You must know there’s no way for me to see a scale I’m standing on, right? Not with this thing in the way.” She gave her rotund belly a couple firm pats for emphasis.

“Yeah, I do know that,” he replied, rubbing the same spot on her belly that a moment before she had been patting, “but I also know you, and that there’s no way you wouldn’t have someone check for you. You’re just too curious not to.” The two stared at each other for a moment, before the flabby mare closed her eyes and sighed.

“Okay, you got me,” Rockslide admitted, holding her hands up in defeat, “as of yesterday, I’m 1,134lbs.”

“Jeez Rocky,” Ferrous said, somewhat shocked, “over eleven hundred pounds?”

“Yup!,” she replied proudly, “it probably won’t be long before I get so big I can’t move anymore, too.”

“Heh, I can’t wait to see that,” Ferrous said as he grabbed a silver pocket watch from his trousers, opening up the face and checking the time. “Oof, don’t have much time left.”

“Oh,” Rockslide said, somewhat crestfallen, “well, it was really nice to see you.”

“Hang on, hang on, I do still have time to help you out with this,” the stallion said as he grabbed the canteen on her hip, unclipping it and unscrewing the cap. “You ready? Again?”

“Yup,” Rockslide replied, giggling softly. She thanked him before opening up her mouth, ready to accept the liquid within. Ferrous then lifted the receptacle up and pressed it against the mare’s lips, tipping it forward until the white, creamy substance began to pour.

For the first couple gulps, Rockslide felt no changes. Soon after, however, the ambrosia began to make itself known. It started off as a pleasant tingling at the tips of her nipples, causing them to expand as they hardened. The sensation traveled down her nips, spreading across her areolas before a new feeling started in the center of her breasts, a comfortable warmth growing into an intense heat. It was then she felt them begin to stretch, her mammary glands working overtime to produce as much milk as they could. The more ambrosia she drank, the faster her breasts filled, growing past the size of beach balls and becoming more akin to yoga balls. As she was very experienced with the effects of the drink, Rockslide knew that the amount she had consumed would be plenty to get her through the next meal time, she would finish up with her boobs about the same size combined as her belly. She expected Ferrous to stop at that point, but the longer he went continuing to tip the bottle forward, the more she thought he might have other plans. Ferrous knew very well what he was doing, and it was not out of ignorance that he kept going.

“Mmph! Mmph!” Rockslide tried to get his attention, but to no avail. The liquid kept coming, and she kept growing. Her tits had now reached the front of her belly, hanging down over it as they swelled into Ferrous’ own chest, ever so slowly pushing him away. The tingling and heat had combined and spread throughout the sloshing bags of milk, making her crotch start to drip with slick, sweet smelling pre.

“Mmph! Mmph! M-mmmmmmm,” her panicked cries were interrupted with a low, sensual moan. Ferrous had brought his free hand down and grabbed one of her rock hard nipples, squeezing it between his fingers and sending a sharp spike of pleasure shooting up her spine. Her pussy was itching badly now, desperate for satisfaction. In an attempt to at least throw some water on the fire, the obese mare rubbed her huge thighs together, the friction calming her aching snatch at least somewhat.

With just a few more gulps, flow of ambrosia stopped, the last few drops hitting her tongue softly. Each breast was now bigger that Ferrous, and they still kept expanding. The stallion himself was forced to the side, pushed away by the unstoppable tide of tit flesh. Bigger and bigger they grew, Rockslide trying to grip their sides, her hands disappearing into the soft sacks of milk. Finally, just as the massive boobs touched the ground, completely obscuring her belly from view, their growth slowed to a stop. The enormous fun bags were so big they gave her ass a run for its money as her biggest attraction. Rockslide herself could only stare at them, not really believing that her girls had gotten so huge. She shifted her gaze to Ferrous, still looking dumbfounded.

“Welp,” the stallion said, smiling happily, “that’s all the time I’ve got for today.” He leaned in and gave her flabby cheek a kiss. “I’ll see you next time,” he said as he moved back to the door.

“Wait!” Rockslide shouted as she tried to turn towards the exiting stallion. The weight of her full boobs dragging on the floor, however, kept her firmly planted facing forward. “You’re just gonna leave? How am I supposed to get back out?”

“Oh, uh, I’ll send someone to get you. Anyway, I really gotta run. I’ll see you later, bye!” And with that he hurried out of the room.

“Wait!” she shouted, but he was already gone. “Celestia dammit,” Rockslide sighed as she looked down to her comically over inflated boobs, massaging what she could reach of them, hands digging into the sensitive flesh. Despite herself, the rotund mare smiled, thinking fondly of the mischievous Cesar, and what he had done. “You’re immature, you’ve got no sense of responsibility, and you do shit like this to me,” she said quietly to herself. She then collected as much of her tits as she could into a tight hug and buried her muzzle into the vast cleavage. “So why do I like you so much?”

Chapter: The Second One

Not many ponies came this way, as was to be expected. After all, access was extremely limited, only her guards, a handful of scientists, and of course, Ferrous himself were permitted to enter the most secretive section of the complex. The entrance wasn’t hidden, it was just about smack in the center of the living quarters. But to the rest of the ponies living here, all this place was was where the infant clones came from. Every two weeks or so, another batch of three to four dozen would be hauled out and split up between caretaker’s who’s previous groups had just graduated.

The entrance itself was fairly large, salvaged from the mechanism operating a pre-war garage door. It had to be big to accommodate the padded carts used to transport the infants to processing. Just passed the door was a long ramp that spiraled down, deep into the earth, the remnants of an old bottling plant. The complex itself had been built around the crumbling remains of the warehouse, while the underground storeroom had been retrofitted into a makeshift laboratory. After, of course, they had removed the thousands of bottles of soft drink that had been piled up everywhere.

Ferrous walked down the ramp with a bit of spring to his step. This was the reason he had come here, and the closer he got the more excited he became. Not even the long, spiraling journey could discourage him, because hey, at least it was better than stairs. After a few more minutes of walking, the stallion finally reach the bottom floor, the ramp dumping out into a wide room with several doors leading in different directions. The dim fluorescent bulbs embedded in the high ceiling provided inadequate light to see clearly, but Ferrous didn’t need it. He knew exactly where he was going. Walking to the left most door in the room, he stopped for a moment and looked up to the backlit sign perched above it. “SUBJECT-01” it said in bold script.

Opening the door, Ferrous mentally scoffed, he hated that name, but it was what the scientists insisted they use. It kept things “impartial” they said, but to him it was straight up demeaning. The guards, at least those that were permitted to know what went on down here, called her the “Brood Mother”, which was a little better, he figured. But to him, she would always just be sweet little Stormy. His sweet little Stormy.

That day had started off just as any other day for Ferrous, the twelve year old colt rising with the sun along with his parents. The sooner he started on his chores for the day, the sooner he could finish, and the sooner he could play with his best friend in the whole world. Well, his world anyway. They lived in a small wooden shack, built many years ago by his father and grandfather. It was only one room, but the fireplace kept them warm and the roof kept them dry. Their home combined with a smattering of others to create the small fishing village of Nordfiske, nestled on the Northeastern coast of the Equestrian wastes, in what would one day become the district of Piscariam Boreus.

His his father left with the other stallions to fish, taking their skiffs to patrol the ice flows in the hopes of catching something substantial. Meanwhile, his mother did her best to maintain their small vegetable garden in the arid, sandy soil, as well as patch cloths and other routine repairs needed around the house. Ferrous hopped to his own duties, heading down to the rocky bay where several long lines had been set up since the previous day. He reeled each one back onto its spool with practiced hands, depositing any fish they brought in into a wheelbarrow. This day had a pretty good haul: seven char, five cod, and even a couple flounders. Not huge, but every fish meant another full belly for that night.

After dropping off his catch at the smokehouse, Ferrous rushed back to the shore, grabbing a spool of line and hopping into his own little skiff. He paddled out into the bay, unspooling the line as he went. Each hook he baited with a piece of last night’s dinner before plopping it into the water and continuing further out. With 30 hooks on each line, it was a time consuming process, and one he would have to repeat four more times, but it made him feel good, knowing that he could be useful to the village.

By midday, Ferrous had completed his task, the young colt rushing through the village to let his mother know that he was going to spend the rest of his day playing.

“Alright,” she said, preoccupied with patching a hole in her husband’s long johns, “but remember, be home before dinner this time, okay?”

“Okay mom!” Ferrous replied excitedly, already running back out of the house, slamming the door shut behind him in his haste. In mere seconds, the boy had found himself standing in front of the door of a shack on the other side of the village, pounding on it with all the might his little body could muster. Almost immediately, he could hear the pitter patter of tiny feet scurrying across the wooden floor inside. Then, the knob slowly turned and the door swung open with a prolonged creak.

Standing in the entryway was a small filly, a head shorter than Ferrous, with a deep blue coat and lighter blue mane. Bright white freckles adorned her face, while her dazzling turquoise eyes seemed to sparkle in the noon sun. Though hidden by a set of hand made overalls, her cutie marks resembled a rain cloud unleashing its payload over a tumultuous stretch of ocean. This was the colt’s best friend since they were babies, Stormwater Seas.

“Hi!” the blue filly said, chipper as always.

“Uh, h-hi,” replied the colt, mostly lost in her brilliant eyes. This caused a giggle to escape from the happy go-lucky girl, giving him a slight punch to the shoulder. Turning around, she shout back to her mother.

“Mommy! I’m going out to play with Ferrous!”

“Okay! Be safe!” came a voice from somewhere inside the house. Stepping out onto the path, Stormwater closed the door behind her before turning around to once again face the colt. She stood there for a moment expectantly, waiting for him to say something. When all Ferrous did was stand there staring, she laughed again and rolled her eyes. Grabbing his arm, the filly sped off away from the house, bringing her unresponsive friend with her.

“Wait!” he shouted, shaken from his stupor in his attempt to keep up, trying his best to not be dragged along the ground by the wrist. “Where are we going?”

“Duh!” she responded, as though it were the most obvious thing in the world. “To the secret place!”

The “secret place”, as it turned out, was actually a pre-war military bunker built into the cliff face along the shore, the entrance hidden by multiple rocky outcroppings. The pair had stumbled upon it one day while messing around, climbing up and down the treacherous rock walls. They had kept its existence all to themselves, not wanting to tell the adults who might ruin their fun. Traveling through the winding corridors, the two made another discovery: this wasn’t just a fallout shelter, it was also an armory. Huge rooms filled with full sets of armor, as well as a full menagerie of weapons. Laser rifles, assault rifles, shotguns, and snipers filled hundreds of weapon lockers. There were a number of robots sitting deactivated in charging stations: protectrons, assaultrons and sentry bots, as well as some of those big metal suits that Stormwater had called “power armor”.

As they spent time exploring the place, they learned more and more about it. Eventually they figured out how to turn on the bunker’s fusion reactor, restoring power and giving them access to the terminals located in the command and control center, deep in bowels of the complex. It was here where this particular trip started out, just like most other visits they made. But today was going to carry consequences that would change their lives forever.

“Well, what do you think?” Stormwater asked, standing behind her friend as he typed away at a terminal.

“I’m not really sure yet, it’s not saying what the problem is.” The screen began to flicker again before Ferrous pounded the top of the monitor once with his fist, fixing it for a few seconds before the flickering returned. “There doesn’t seem to be anything wrong with the terminal, but I can’t seem to...Oh! There it is!”

“What!? What is it?” the filly asked excitedly.

“There, in the error logs, ‘Insufficient power to run program’.”

“Insufficient power? Well how do we get sufficient power?”

“Hold on, i’m looking,” Ferrous said as the flickering resumed, making it almost impossible to read what was on the screen. “Gah! Stupid thing!” He searched through every file he could think of on the machine, going through system after system, skimming directories until finally he came across the diagnostics program.

“Okay, here we go. ‘Reactor malfunction, fuel rotator cuff damaged, please replace.’ It even says where to get a new one, they’re down in the maintenance storeroom.”

“Okay, so we fix the thingamawhatsit, and the power goes back to normal?”

“Looks like,” Ferrous replied, getting up from his chair. “Alright, let’s go.” The trip to the reactor took only a minute or two, the pair standing in front of a consol below a thick polycarbonate window with a full view of the generator, and a large metal door separating them from the machinery inside. Ferrous pressed a large red button located in the center of the consol with the word “OPEN” written in bold font. But instead of the door sliding open, as they expected, a robotic voice called out from speakers attached to the ceiling.

“Master clearance required to access restricted areas. Please insert identification.” And with that, a small black slot on the consol began to flash, blue, arrow shaped lights telling which way to swipe a card. The pair looked at each other, confused.

“Master clearance? What does that mean?” Ferrous asked his companion. Stormwater didn’t reply immediately, holding a hand over her mouth as she thought.

“Hmm,” she said after a while, “do you it means that thing with the picture of the old guy on it? It looks like it would fit in that,” she said, pointing to the card reader.

“Stormy, you’re a genius!” the brown furred colt exclaimed, causing the filly’s cheeks to flush a light pink. “Here, hold this. I’ll be right back.” He thrust the equipment he was holding into her hands and ran off back to the control center, leaving her there still blushing faintly.

When he returned, Ferrous went straight up to console and inserted the card, sliding it into place. Immediately the robotic voice range out again with a curt “Access granted.” Then followed a loud, piercing alarm, as well as a pair of flashing yellow lights affixed above either side of the large door. A moment later, the door began to slide, the grinding and squealing, as well as the bits of rust it shed as it went along, betraying its hundreds of years of disuse. When the door had fully opened, however, what it revealed was not what they had been expecting. Instead of the reactor, all that was beyond it was yet another door. Once again, the robotic voice chimed in. “Please enter the decontamination chamber.”

The two simply stood there for a moment, not sure how much they wanted to proceed, until Ferrous turned to his friend. “W-well, what you waiting for?” he said to her nervously.

“What? Why me?” she responded, clearly apprehensive about entering such a well guarded place.

“Because, you’re already holding the thing!” he said, giving her a gentle push towards the opening. “Come on Stormy, don’t be such a baby.” Very slowly, the filly began to walk into the room, gripping the replacement part tightly to her chest, as though it would provide some sort of comfort.

When she had fully entered the chamber, Ferrous pressed another large button on the console, this time a bright yellow one labeled “CLOSE”. Once again, the big door screeched to life, slowly closing until it had shut with a hiss of pressurization. Finally, the annoying klaxons and flashing lights ceased.

From inside the chamber, Stormwater watched as the second door in front of her began to open, slowly revealing the towering machine she was there to fix. Instantly she felt something was wrong. Though her core was cool in the chilly metal passageways, her skin began to get hot, almost unbearably hot. In addition, she could feel a strange buzzing sensation bouncing around in her head, creating a strange tingle in the base of her jaw. Steeling herself, the filly closed her eyes and tried to ignore the discomfort, taking a deep breath before once more facing her objective. Daintily, she stepped out into the poorly lit area, taking a moment to observe her surroundings. The room was curved with smooth walls, almost like a big, round pit. In the center was the hulking device, a low, droning hum emanating from somewhere deep within it. To her left was the curved window looking back out, Ferrous eagerly waving to her from the other side.

“Hi!” his energetic voice echoed all around her, though it was slightly tinny. There must have been an intercom in here as well, somewhere. Her response was to give a single tentative wave back, still clinging to the cuff, her face clearly showing her anxiety.

“Okay,” came his voice again, “do you see the pipe running up from the ground into the big round thing on stilts?” Stormwater turned her attention back the machine, locating what it was Ferrous was talking about. Slowly she approached it, that strange buzzing getting louder with every step.

“I’ll take that as a yes,” Ferrous said sarcastically. “Okay, at the top of the pipe there’s a frisbee lookin’ thing just like what you’re holding. You have to undo the latches holding it in place, then put the new one on.” She could barely hear him at this point, the unnatural noise sounding like a swarm of wasps had invaded her brain. She worked quickly, squinting and clenching her teeth through the pain. She undid the first latch, and then the second. After releasing the sixth and final clamp, she carefully removed the disk. All at once everything she had been experiencing increased ten fold, hitting her like a flood and almost knocking her off her feet. She couldn’t hear anything anymore, not even her own screaming. She lost all sense of touch as well, only able to feel the intense heat.

As quickly as she could, Stormwater replaced the cuff and fumbled with the locks, wanting nothing more than to be out of that room. As each latch was hooked, the tormenting force dimmed, until finally it was back to the level she had experienced upon first entering the room. Leaving the broken part on the floor, the desperate filly ran back to the open door, entering the chamber and going right to the barrier separating her from security.

“Open! Open! Open!” she cried through tears, frantically pounding on the metal gate. Ferrous quickly punched the “OPEN” button a second time, the flashing yellow lights and blaring sirens starting up again. Inside the chamber, the door to the reactor slid shut, Stormwater still banging away on the other side. Once it had closed completely, the filly was drenched in what smelled like soap, sprayers in the ceiling offering a downpour of the sudsy liquid.

After about a minute of soaking, the flow abruptly stopped, the same robotic voice declaring, “Decontamination complete.” Finally, the outer doors began to once again grind their way open. The moment a space large enough appeared, the little filly ran out to freedom, and right into the waiting arms of her companion.

Gripping his shirt tightly, Stormwater leaned her entire weight into Ferrous, knocking them both down as she openly cried into his chest, burying her forehead under his chin. Ferrous wrapped both his arms around her, giving the scared filly a comforting squeeze. “Hey, it’s okay. It’s okay,” he said gently, not minding his clothes getting soaking wet. They stayed like that for almost half an hour, until she had finally calmed down enough to get up and go home. They told their mothers that she had fallen in the water by the rocks, agreeing to continue to keep their discovery a secret. It wouldn’t be until much later that they would learn that that amount of thaumaturgic radiation should have been more that enough to kill her.

At first it seemed there would be no consequences from Stormwater’s unwitting brush with death. A year passed and nothing seemed to change. However, as the filly went through puberty, and made the transition to becoming a mare, it became clear that she wasn’t the same as the other girls in the village. The first difference that made itself known was how easily she could gain weight. Despite the fish stocks being down for a couple seasons, Stormwater went from being a rail thin preteen to a fairly chubby teenager. At 15 she had already passed 200lbs, making her heavier than many of the full grown stallions. This started rumors that her parents had been sneaking extra food when nopony was looking. In fact, it had gotten so bad that the village elder had to step in and essentially tell everypony else to knock it off and leave them alone.

The next development was one that caused even more suspicion, though this time predominantly among the mares of town. By the time she was 16, Stoermwater’s bust was by far bigger than any other mare’s. Not only that, but her then cantaloupe sized boobs wouldn’t stop getting larger. Every other week, the developing mare had to get her bra let out.

And that led to the final, strangest change. When she was just 17 years old, Stormwater became pregnant. The only problem was, she was most definitely still a virgin. Of course nopony else believed her. They all just thought she and Ferrous had gotten frisky, the did spend nearly every day together, after all. Except that theory started to fall apart quickly as she progressed. Each day Stormwater’s stomach stretched out further, forming a large baby bump just days after she had found out she was even pregnant. After just two weeks, she had given birth. What also shocked everypony involved was that this baby looked strangely, no, freakishly similar to a little colt who had been born only six months before.

She didn’t keep him, another family offering to adopt him before they trekked out of the village, heading further south. Everypony tried to simply forget what had happened, and pretend that it hadn’t. That became very hard when just a couple months later, she and Ferrous were gawking at how cute a newborn filly was, and the next day she had woken up with terrible morning sickness. Sure enough, two weeks later out popped a living replica of that exact filly.

Stormwater didn’t know what to do. No pony was willing to adopt her this time. She was forced to take care of this filly, which lead to the discovery of yet another strange anomaly. It was after this pregnancy that Stormwater began to lactate, her now watermelon sized breasts filling up for the first time. As the filly suckled from her mother’s tit, it became clear that she wasn’t developing normally. After just two months, she was already walking, and by six months she was forming full sentences. At eight months her baby teeth began falling out, and at ten months she was just as tall as Stormwater. It was at this point she decided to cut her “daughter” off, feeling too weird about someone who at least looked as old as her nursing from her.

The filly herself, despite looking “normal”, clearly wasn’t entirely standard. Perhaps it was her accelerated maturation not giving her brain enough time to properly form, but she seemed...different. She was intelligent enough, she followed directions fine and she gave clear and appropriate answers when asked a question. But she lacked a certain independence that most other fillies her “age” were supposed to have. It made her fairly easy to deal with, but for Stormwater, it kinda freaked her out. Well, freaked her out more anyway.

It was all very distressing to Stormwater and her family, but to Ferrous and his young mind, it was starting to give him ideas. Through subtle, inconspicuous experimentation, he learned as much as he could about her strange inner workings. He ascertained that Stormwater didn’t even need to see a living pony to get unnaturally pregnant. If he could make her feel strongly enough about a drawing of somepony, even one completely made up, two weeks later out would pop an exact copy.

Slowly, Ferrous used her to build his army, using the supplies found in the armory to supply his custom designed soldiers, until finally, he was ready to strike.

All of that planning, all of that building, lead up to now. Ferrous was the king of his castle, the ruler of over a million ponies, but he would never forget the mare that had made it all possible. He strolled quickly through the short connecting hallway, passing another pair of guards as they bowed to either side. Finally, he came to the last door, the final barrier separating him from the one he loved. As he pushed it open, he began to grin wildly as his sweet little Stormy came into view. Although, there was absolutely nothing “little” about her any more.

The room itself was fairly large, probably the size of a small ballroom, and dimly lit. This was the place the old soda plant had kept their stock ready to be shipped. What took the place of soda now, was a daunting figure sat in the center of the chamber. And by Celestia was it, or rather, she massive.

From the angle where Ferrous stood, all he could see was one incredible, deep blue mound that squished out across the floor, swelling up to more than twice his height. As the stallion walked to the side, another mound came into view, joining its twin along a deep crevice that stretched their entire length. Close to the top, a relatively tiny tuft of light blue hair stuck out between the hills, revealing the identity of these monuments to excess. Ferrous was in fact gazing upon the biggest, fattest pair of ass cheeks that he had ever seen, each one nearly the size of an elephant.

Walking up to one cheek, Ferrous reached out and placed a hand onto the round surface, delicately stroking the silky fur that covered it in long, sweeping circles. Slowly he pressed his hand into the yielding flesh, letting it sink further and further in until his shoulder had disappeared. Then, he repeated the process with his other hand, both arms now fully inserted. For support, he leaned into the jiggling mass, most of his legs and torso submerging as well. Now that he had almost entirely been consumed by Stormwater’s colossal butt, he squeezed his arms together, collecting as much ass fat as he could and pressing his forehead into it, giving the soft, warm fat a loving kiss as well.

Extracting himself from the warm embrace of her rump, Ferrous continued walking around the gigantic mare, dragging three fingers through her side as he went. Her cutie marks, now the size of billboards, were so stretched and distorted that they were almost unrecognizable. Looking up, he could see a single arm, or really, a round sleeve of fat under which an arm lay. All that was visible were her fingers, looking less like a hand and more like nubs protruding from a rolled up blanket.

As he reached her front, three distinct shapes came into view. Her belly spread out over the floor, completely swallowing her legs while also creating a shelf upon which two breasts, each about the size of the cart he rode in on, sat comfortably. Ferrous tested the feel of the over inflated milk bags, pressing into them and reveling at how soft they were, though with an underlying hint of firmness.

From his position, Ferrous was unable to see Stormwater’s head, however he could hear a quiet, gentle snoring coming from the top of her humongous body. Reaching up, he gripped the closest tit, digging his hands in and using it as leverage as he lifted himself up unto the mountainous bossom. Once on top, he straddled it between his legs, scooting forward while being careful not to get thrown off by the sloshing waves his movement caused.

Upon summiting her boobs, Ferrous climbed up carefully and positioned himself to place his face in front of hers. He smiled as he watched her sleep, her massive cheeks dimpling and her multiple chins transitioning smoothly into the tire of fat that swaddled her neck. Directly behind her head, the bulbous cheeks of her butt pressed up against her, and still continued to swell upwards for a few more feet. As she slept, she leaned her head back and into the soft ass fat, using it as a natural, ever present pillow.

Reaching out, Ferrous gently caressed one of Stormwater’s big cheeks, running his thumb up and down in a soothing manner.

“Stormy,” he said softly. “Hey, Stormy.” Slowly, the beyond obese mare’s eyes drifted open, her pupils dilating slightly in the dim light. With her vision still blurry, she yawned intensely, smacking her lips together and wetting her tongue. As the world came into focus, she began to recognize the figure that was peering at her.

“Ferrous?” she asked groggily. Once her vision was fully clear, and she could plainly see him nodding in front of her, Stormwater broke into a broad smile, her fat face creasing in her joy.

“Ferrous!” she shouted, and for a moment the stallion thought he could sense movement under him, as though the big mare had attempted to use her atrophied muscles to move the thousands of pounds of fat covering any one part of her body. “It’s so good to see you,” she continued, “I’ve really missed you.”

“I missed you too,” the stallion replied before leaning in and connecting his lips with her’s. The two stayed like that for several seconds, enraptured in the kiss as their tongues danced together. After breaking, Ferrous leaned in further, nuzzling his cheek against her much fatter one. “We don’t see each other enough,” he lamented, pulling away to resume gazing into her beautiful turquoise eyes.

“You’re telling me!” she exclaimed with a bright laugh. “Without you here, all I have to do is sit on my big ass and pump out babies! At least you’re not too fat to move!”

Ferrous laughed as well, happy beyond words to hear his love’s cheery voice once again. “Well, you’ve got me there, honey.” He leaned back in and took another quick smooch. “So how have you been? Besides, ya know, the whole ‘too fat to move’ thing?”

“Ugh, bored! That’s how i’ve been!” she said exasperatedly. “I mean, don’t get me wrong, feeding time is always nice. But when I’m not eating, I don’t have anyone to talk to! The guards are terrible for conversation!”

“Hm,” Ferrous mumbled, stroking the brown tuft under his chin with a thumb and index finger. “There may be something I can do to help with that.”

“Oh?” Stormwater replied, lifting her eyebrows in optimism. “How?”

“One of the caretakers, one I know very well, likes to eat almost as much as you. In a few more weeks, she’s probably beach herself just like you did.” To emphasize his point, Ferrous wound back a hand and slapped the bed of belly fat he was currently laying on, sending it, as well as himself, wobbling heavily. “Once her butt pins her to the ground, we can probably roll her in here and she could keep you company.”

“That’d be awesome,” the big mare said, “but doesn’t she still have to take care of a batch?”

“Eh,” Ferrous replied dismissively, “we can just get a new one. Motherly mares aren’t really hard to find in the empire.”

“Oh, you’re too good to me. Come here,” she commanded, and Ferrous was only too happy to oblige. They locked lips now for the third time, this one even more passionate that the first. Once they separated, Stormwater looked at her lover with an almost predatory gaze, clearly hungry for something other than food.

“Now,” she said with a husky tone. “I know you’re not just here to chat.”

“Oh, frisky already are you?” Her only response was a giddy smile. “Well then, why waste time?” With that, the stallion slid back down the way he came, using her boobs as a ramp before planting both feet onto the ground.

To begin, Ferrous began massaging the mare’s enormous tits, running his hands up and down, pressing into them and sloshing the hundreds of gallons of milk within. His movements elicited a deep groan from atop the mountain of lard, a sign for him to keep going. Focusing on one breast, he slowly massaged towards the tip, cupping his hand over her wide areola and rolling her rock hard nipple between his fingers. More moaning followed, as well as a small drop of white liquid seeping out of the erect teat.

“Mmnnnuh, huff, ha,” was Stormwater’s response, a mix of moans, groans and panting. Her pussy warmed up as juices began to drip from it, soaking the fur that surrounded it. With her vagina buried under thousands of pounds of both thigh and belly fat, as well as her arms being locked to her sides, Stormwater was incapable of pleasuring herself. The last time she had received any satisfaction was Ferrous’ last visit over two months ago. The stallion in question continued teasing her nipple, causing an unbearably wonderful tingle to flood across her sensitive boobs, joining the one tormenting her underused snatch.

“Careful baby, my t-tits are so fucking f-fuuuuuu, oh sh-shit, huff, full.” And she wasn’t lying. Ferrous had requested that to prepare for his visit, the staff would refrain from milking her for a couple days, the result being outrageously full, and incredibly tender breasts.

Leaning down, Ferrous wrapped his lips around the nipple, caressing it with his tongue and eliciting a squeele of pleasure from the blimp of pony. Puckering his lips, he gave it a long, hard suck, a torrent of delicious, warm milk flooding into his mouth. He swallowed it all in one gulp, immediately going for another pull, guzzling down all that he could. Again and again, Ferrous suckled from his lover’s tit, a line of the white liquid running down his chin. Stormwater herself was only able to huff and puff, lost in the overwhelming sensations flooding her brain.

As Ferrous drank, the milk’s mutagen properties began to take their effect. When consumed by mares, massive weight gain and overproduction of the same altered milk followed. When consumed by stallions, however, a completely different set of effects took hold.

Almost instantaneously, Ferrous could feel the start of these changes. Within the stallion’s balls, a warm, fluttery feeling accompanied the rush of blood into his penis. As his dick inflated, so too did his testicles, the organs stretching like balloons as they produced more and more semen. Like his balls, Ferrous’ penis grew quickly. But instead of stopping at its normal length, the sensitive organ continued to swell, growing past all manner of sensibility.

It was now that the horny stallion had realized that he had forgotten to take off his pants before starting, an error that would spell the end for this pair of trousers. His dick and balls pressed tightly against the leather garment, stretching and tearing seams as they went. Eventually, the front of his pants burst open, revealing the full glory of his genitals to the world.

At this point, Ferrous’ pecker was 16 inches long, and still it continued to grow; 20 inches, two feet, three feet. The organ pushed out, growing not only in length, but girth as well. And his genitals weren’t the only things growing. Though by comparison it wasn’t much, the stallions muscles also began to pump up, pecs hardening into dense plates, abs appearing where they hadn’t been before, and biceps stretching into the size and shape of cantaloupes. He would need the extra strength, as when his growth finally stopped, his reproductive equipment was well and truly massive.

Ferrous’ penis was now nearly five feet long, rising just above his head, and as thick as his newly muscled arms. He placed a hand on its veiny shaft, causing a thick glob of pre to squirt from its tip. Below, a pair of testes the size of basketballs hung suspended in their fuzzy sack.

Now fully equipped, Ferrous walked around Stormwater until he reached her titanic butt, looking up at the mounds of fat that towered above him. Gently, he pressed his shaft against her ass, slipping it between her furry cheeks, bringing a deep grunt from the stallion and a soft moan from the mare. After a few seconds of hot dogging, Ferrous then, completely wordlessly, thrust his tip deep into her crack, and continued pushing until finally it found paydirt.

The swollen tip pressed hard against Stormwater’s anus, a shocked scream escaping from the immobile mare. In a single, smooth motion, Ferrous thrust into her waiting entrance, stretching it open to accommodate his inflated package. As the pumped up stallion thrust, his hips pounded into the soft globes, sending them quaking violently. To prevent himself from being knocked backwards, Ferrous had to grab ahold of the blubbery glutes, shaking himself in the process. He continued to rail her in the ass until finally, after several minutes, he felt the familiar pulsating flow from his tip to the base of his shaft.

Abruptly, Ferrous pulled out from Stormwater’s ass, being careful not to so much as breathe on his throbbing dick so as to preserving his orgasm. Awkwardly, he waddled back to her belly, swollen balls swaying in front of powerful legs, and saddled up with his tip pointed directly at it. Slowly, he pushed his enormous penis underneath the apron of fat, gritting his teeth and clenching hard to avoid cumming all over the fat mare’s undercarriage. Using his newly muscled arms, he lifted her big gut, or at least some of it, to ease his dick’s passage. As he went, he could faintly feel the firmness of a newly minted batch, not yet developed enough to show under her layers and layers of belly fat.

Ferrous felt the change in pressure as he plunged into her thighs, the compressed fat on either side squeezing hard against him. At last, he felt his tip press against the wet, puffy lips of her slit, Stormwater letting out a gasp upon contact.

“Oh, f-fuck!” she moaned. “Do it baby, send my fat ass to heaven!” Ferrous was not one to object. He pushed himself into her, his hips slamming into the soft belly and sending it wobbling. In and out he went, gripping onto her colossal boobs for support. Stormwater went cross eyed, her neglected pussy now screaming in pleasure as it stretched to fit Ferrous’ massive package. Biting her lip, the immobile mare closed her eyes and leaned her head back, pressing it into the pillowy softness of her ass cheeks.

Ferrous could feel his finale approaching, pumping harder as the sensations reached their peak. With his hardest thrust yet, white, sticky cum exploded into his lover, filling her to the brim with fresh seed. The powerful orgasm racked his body, sending his muscles twitching in ecstacy. But after a moment to enjoy his high, Ferrous resumed his pumping. Stormwater was not yet over the edge, and he wouldn’t stop until she was satisfied. He soldiered on, ignoring the slight stinging of too much friction on his stretched out dick skin, until finally she reached her own climax, her snatch gripping and clenching around his already spent tool. A loud “Yes!” came from atop the jiggling mountain of fat.

Ferrous carefully pulled out, puffing slightly as he recovered from the intense round of sex. Once again, he climbed the slope of her breasts until he was level with her round face. Without even a word, the exhausted stallion went in for a deep kiss. The pair could feel the heat from each other’s cheeks as they made out, their steamy session having worn them both down, though to be fair, it didn’t take much to tire out Stormwater these days.

As they separated, the rotund mare cooed, smiling widely. “I love you Ferrous. I love you so much.”

Ferrous reciprocated her smile and pushed the tip of his muzzle into hers in a gentle boop. “I love you too, Stormy.” With that, the pair closed their eyes and drifted off to sleep, Ferrous nestled cozily with Stormwater as his big, plush mattress.

Ferrous zipped up his new pair of pants, finally able to fit in them now that he had shrunk back down to his original proportions. He walked casually alongside a lab coat-sporting stallion as the two made their way down a dimly lit corridor.

“So,” Ferrous started, “how are the tests coming along?”

“Very well sir,” the gray furred unicorn responded evenly. “In fact, they are exceeding all of our expectations. It seems we have identified precisely which operons can be manipulated to code for the desired phenotypes. And fortunately, the retro subclinical delivery vector achieved a 99.95% transmission rate, meaning that only one exposure was required to be administered.”

“So,” Ferrous said slowly, shooting a confused glance towards the bespectacled stallion. “It worked?”

“Yes,” the scientist responded, a cheeky grin on his face as he returned Ferrous’ gaze. “It worked. See for yourself,” he said as he gestured to the end of the hall. In front of them was a very ordinary looking door set into the wall, and on its right was a long pane of glass looking in to a fairly spacious room. Ferrous stepped up to the window and peered into it.

The decor was somewhat homey, with a cool yellow wallpaper and brown wooden trim. Landscape paintings hung from the walls, and a pair of large bookcases dominated one corner. Along the back wall, underneath a ticking clock, sat a pony in an old wooden chair. The mare, a pegasus on account of the folded wings peeking out from behind her back, was very young, not much older than 20. She had soft pink fur and a flowing purple mane, as well as big, blue eyes. But those were trivial details as far as Ferrous was concerned.

The stallion’s eyes drifted over the unwitting mare’s body, enjoying what he saw. Her butt completely filled her seat, two soft booty cheeks flowing over the top of the chair. Her plush hips and thick thighs poured through the space both under and over the armrests, nearly swallowing them completely. The stretchy black leggings she had somehow gotten her fat ass into sported several tears along its seams. The mare’s swollen breasts sagged freely, unbound by clothes, as she held a leather bound book to her cherubic face. Serving as a platform for her heaving boobs, was the mare’s wonderfully pregnant belly, surging out to extend beyond her knees. As she read, the mare rubbed one hand over her straining gut, the taught organ looking like a yoga ball sitting in her lap.

Ferrous stepped back from what was evidently a two-way mirror, still staring at the amazingly turgid mare. Slowly, his eyes drifted upward to a sign sitting just above the door, struggling slightly to read the dark lettering in the inadequate light.
