Commission for Iron99 on FA. Caught, and subjected to animal testing... Well, a form of it at least, isn't something that Iron planned for. The snacks and benefits are pretty darn great though!


Iron knew something was up with the treats being offered to him. The coyote was suspicious of them, of course, but he had yet to eat anything since he had been captured, and that had been nearly a day before. He had been out, wandering throughout the desert as he was one to do, and then suddenly... Nothing. He remembered feeling a small prick in his side, not unlike the stab of a cactus' spine, but even that memory was somewhat vague. He couldn't place what had happened next, only that he remembered the pinch, then blackness. When he had awoken from that dreamless sleep, something he was hardly accustomed to as he often had food-laden dreams filled with all the meat he could ever want, the canine was trapped. The enclosure he had woken up in wasn't small or confining by any means, but it was nonetheless an enclosure. The coyote wasn't used to being trapped, and as such, he just wandered around and sniffed out the new room curiously for a few minutes before truly realizing that there was no way out of the room. He tried digging against the dirt floor, running into the walls... Anything and everything that his feral mind could think of, and yet it was all for naught. Nothing was going to get him out, and so Iron had just laid down in the middle of the room and whined for release; he didn't like this new habitat.

He had been there for hours before his captors finally showed their faces or at least one of them. This captor looked to be an anthro ursine, though Iron wasn't used to dealing with anthros as they usually shunned ferals like him. Backing away from the bear at first, Iron temporarily forgot that he was trapped in the room with the ursine. He remembered, however, the second his backside touched the wall behind him, pressing into it slightly before the canine realized his predicament and began to growl in nervous anger. Iron wasn't one to fight, but being approached by the towering bear was enough to intimidate him plenty, and with nowhere to scamper off to, the coyote knew he would need to stand his ground. This didn't come to pass, though, as the bear just leaned down and extended a paw instead of attacking. In that outstretched mitt, there were treats of some sort... Ones that Iron had never seen before. He had managed to scrounge such things from anthros' homes before, sneaking in and rooting them out, but these ones smelled slightly different from what he remembered. Their scent was more... Chemical-laced, but it wasn't quite enough to deter the coyote. He approached cautiously, his ears still pinned back against his head and his tail drooped between his legs in fear as he did so. Plodding over, cowering almost before the bear, the canine gave an experimental sniff to the treats again to further confirm that they were something he could eat. Satisfied, Iron snatched the treats from the bear's paw in one swipe of his muzzle, gathering them all up into his muzzle with nary an issue; there had been a full pawful, but Iron was an expert at using his entire mouth. This fact was evidenced by his build; he didn't have the normal lithe physique of most of his ilk. No, Iron was filled out nicely, not fat, but certainly not the normal, emaciated look that coyotes were known for. Pleasantly plump, he remembered a woman calling him... And he couldn't help that fact; food was just too good to pass up, and as he scampered off with his muzzleful of treats, the canine couldn't help but remembered that fact.

***********

"Subject has taken the bait," the bear said with a hint of excitement in his voice, stepping out of the hidden doorway in the enclosure and into the hall beyond. Another ursine, this one smaller all around than the first, looked up from a computer and gave a small grin.

"Excellent. Did you give the subject just one like we agreed?"

"Just one? The notes said to give a full pawful..." The first ursine replied, the color draining from his face as the second bear stood up in shock. Quickly typing out the mistake on the computer, the smaller bear went just as pale as the first as numbers began to flash on the screen; red, angry numbers. The bear turned towards the first with a look of both anger and terror on their face; clearly, the numbers weren't what they wanted to see.

"T-That bad?"

"Did you at least give them the newest batch?"

"The notes said Batch 86," the bear responded, causing what little color was in the smaller bear's face to drain even further. More typing, more angry numbers, and even more anger finding it's way onto the ursine's face.

"Who... In... The... Hell took those notes?!"

************

Scarfing down those treats, Iron hadn't noticed the first ursine leaving the room. The coyote was too enraptured in his first morsel to eat in nearly a day, and he devoured it as such. Of course, once he did... The canine immediately knew something was wrong. He could feel something in his stomach just gurgling with anger, and it made the coyote squirm a little bit in place. He didn't quite know what to do, as his stomach just gurgled and groaned for a few moments once the treats had been consumed. That gurgling and groaning didn't go away, though, instead getting louder with the passing moments until it was nigh constant for the coyote. With that increased noise from his stomach, the canine started to feel hungry... And then famished... And then a level of ravenous that he had never experienced. Being a scavenger, he had gone a day or two without food before, and that always left him starving. This was some new level of hunger that he had never experienced before, though_;_ he _needed_to eat something. The canine's eyes went wide as he began to frantically look around the room, his muzzle contorting into a snarl as he winced with the pain of hunger pangs wracking his body. Every bit of him wilted slightly as these waves of hunger just assaulted his very being, from the tips of his pointed ears to the end of his fluffy, drooping tail. All of the deep-brown fur on his back was on end, making the large coyote look even bigger as he fluffed up in a fearful response to what his body perceived as an attack. Iron was becoming desperate, and as such, his body was going into attack mode.

Mercifully, an answer to his predicament appeared mere moments after it began. A hose of some sort descended from the false sky above him, the thick, opaque tube lowering itself down into the middle of the room. Iron, still curious despite the fact that his stomach felt as though it was trying to eat itself more and more with every passing moment. Iron slowly trudged over, snarling and panting in pain with every step that he took as even the light coating of fat already on his frame moving was enough to shake his stomach, and that in turn just shook even more hunger pangs loose from the tumultuous organ. It was agony for Iron, but as soon as he reached the hose and gave it a sniff... The canine knew that his problems would be solved. That sniff gave away that there was pudding of some sort in the pipeline, and he was going to get at it no matter what. Picking up that hose with his mouth, the malleable plastic at the end of it easily contorted to fit inside his jaws. His teeth bit down through that plastic as he subconsciously tried to eat even that, but thankfully there would be no tearing of the material in his muzzle; his teeth just got stuck in it. Sliding his tongue into the tube, Iron licked what few bits of pudding he could from the inside of the hose in desperate need of something, anything to eat. He then swallowed hard, hoping that those few drips of something edible would be enough to quiet his stomach. This had the opposite effect, though, as his gut just groaned louder and demanded more now that it had been given something to satiate the strong need it had for food. Iron collapsed to the ground in pain as another hunger pang wracked his body, yowling out around the hose as it stayed tightly trapped by his teeth and his body's involuntary need to try and chew through whatever was in his mouth. Food was now beyond necessary for the canine; he felt like he would die if there was nothing to eat...

Mercifully, somewhere up above him, the gods had heard his pleas and send down exactly what Iron needed. The hose in the canine's muzzle twitched, making Iron open an eye a small bit just to see what he could of the hose. In that hose, more pudding looked to be flooding towards him, the hose bulging out greatly just above where he was. That sight alone was enough to make Iron's eyes bulge open in surprise, but that surprise paled in comparison to the shock of just how much pudding came racing down into the coyote. Iron had mistakenly latched onto a water hose before, so he knew what it was like to be pumped full of liquid, but this was an entirely unique experience for him. His cheeks bulged to their maximum capacity in an instant, his throat seemed to lose the ability to swallow as the liquid forced itself down into him, and his stomach... Oh that poor, tortured organ now had all the food it could ever want. Thankfully, the fact that Iron had bit down as hard as he had into the plastic nozzle at the end of the hose meant that none escaped his maw, and as such, there was no mess to worry about as he ate... But, more importantly, none of that food went to waste. No, every single drop of the onslaught of vanilla pudding the hose pumped out went straight into Iron, and as such, the canine began to expand like a balloon on a faucet. It was subtle at first, his empty stomach just filling itself back out to the small ball that it rounded into once Iron had eaten a hearty meal. From there, though, his stomach began to grow further, expanding out past just full. The coyote blew right past stuffed, filled, and cram-packed with food in less than three minutes on the hose, and before he knew it, the tan fur on his stomach looked to nearly be thinning thanks to just how much his stomach had inflated in such a short time. The worst part of this? His hunger pangs hadn't gone down... No, they were still wracking his body, but the feral coyote was at least given a modicum of solace in that he was no longer painfully hungry. He just had an innate need to eat a lot more than he had, but with a quick glance back to look at his hanging stomach, the canine wasn't quite sure just how much more he could take.

Right as Iron reached the point that he felt his bulging ball of a gut could take no more, another weird phenomenon reared its head for the canine. His stomach began to empty at the same pace it was being filled, and with it's emptying... Fat began to pile onto the feral coyote's frame at an alarming rate. Digestion had kicked in at the same pace as his consumption, meaning that Iron was left feeling breathlessly full, and fattening like the pudding he was being forced to consume by the gallon was going straight into his hide. His legs blimped up in moments, his haunches going from merely soft around the edges to bulbous and sagging just as fast. His stomach, which already looked like a basketball glued to the underside of an average canine, swelled out with fat rapidly. The bulk of Iron's weight gain, in fact, went to that part of his frame, bringing him from simply an overfull coyote to a first-class hog of a canine in no time flat. His stomach wasn't alone in that ballooning though, rolls of fat finding their way onto Iron's back quickly as his shoulders filled out and began to sag lightly. The canine's chest, neck, and even his cheeks all bloated with fat, Iron expanding out to be just a porker of a coyote as though he had been on that steady diet of pudding for years, and not minutes. Whimpering and whining, the canine couldn't make heads or tails of his situation, but he couldn't deny that something about it felt just intoxicatingly good to him. To feel this much size was certainly odd, and something he hadn't expected ever... But he was now easily the biggest coyote he had ever seen, and with the flow of pudding showing no signs of stopping, the canine knew that he was going to get bigger yet. His stomach was already brushing the ground, causing Iron to involuntarily arch his back to keep that overfilled balloon of food from pressing down beneath him. That effort was short-lived, though, as the fat on his frame was too attracted to the ground to let them be separated for long. As such, Iron's legs were becoming too overburdened with the newfound weight of their owner to stay vertical for long. Shakily, Iron fought against gravity to the best of his abilities, but... It was a losing battle for the canine. His stomach was going to win that fight, and as it began to push out against his ankles and splay his legs too wide to even fully reach the ground, Iron knew that he had lost. As such, he just gave up and let his whole weight sink down onto his stomach, his legs coming up to rest against the sides of his swollen stomach as they left the ground for what Iron, somehow, knew would be the last time. He was now beached, immobile, trapped... And while being a coyote meant that process was somewhat terrifying, at the same time, Iron felt the power of being so large somewhere in the recesses of his mind. Now, if only he could get out of that room...

**********

"Subject is immobilized, already." The smaller bear noted down, annoyance clear in their voice. The larger bear, standing behind them, just looked down at the floor in silence; clearly, they had been given a proper dressing down from the smaller ursine. "Progress is even faster than noted in simulations, with no sign of any change in the hunger of subject. Subject will consume the entirety of tank B-6, and then the countermeasure shall be given in order to allow for further testing and caretaking. Damage to the facility for one tank should be minimal, but within expected parameters for such a malfunction in testing."

"Uhm..."

"Yes, what is it?"

"They're servicing the tanks tomorrow, boss..." The larger ursine started, causing the smaller bear to whirl around and glare up at the bigger bear with a look of pure anger on their face. "You got the email about it this morning," the bigger bear continued, seeming to almost wilt from the intense glare they were on the receiving end on. "Maintenance already did the prep work for it, and the shutoff was disengaged right after..."

"You mean..."

"Yes ma'am..."

"...Shit."

***********

Iron was still growing like dough in the oven, rising up further and further on the balloon of his stomach beneath him. His limbs, head, and even tail were starting to sink into the all-encompassing fat of his frame, but the canine didn't give this even a second thought. He was now content as could be, thanks in no small part to just how much size he had managed to garner. He was spread out throughout the entire room that he had been trapped in, filling it from edge to edge, and his fat was beginning to climb those walls. With that, he had also grown closer to the false sky above him, something that his ears were starting to press against on rather hard gulps of the creamy pudding. Iron felt beyond just powerful at that size, for even though he could scarcely move a muscle or see anything over his own chocolate cheeks, the canine just felt big. That size was something he was getting used to as fast as he was gaining it, and as such, he got to enjoy it. He didn't enjoy not being able to move, and the tightness of the room was starting to get to him, but he could feel the walls starting to give all around him. The pressure of his fat was turning out to be too much for the sheetrock and wood, which kept him in place, and as such, Iron knew it would be only a matter of time before he exploded out of the room. Iron didn't know of any other coyote who could take down walls without lifting a muscle, and that made him feel even more powerful. First, though, those walls needed to give way around him... And then the sky was the limit for the binging bulge of blubber.

Seconds later, the walls gave way to Iron's weighty hide, and from there, the canine truly just grew. Out of the confines of the small room, Iron spilled out into hallways around him, then through other walls, and from there, he just continued to grow. The hose was still pumping hard, the coyote was still feeling stuffed in every sense of the word, and yet he was still just growing at the same pace he had been since the entire experience had started for him. As such, it was mere minutes before he was pressing into walls again, and then some more minutes for more walls... And about an hour later, the very building that was struggling to contain the coyote was starting to crumble. Iron couldn't see anything at that point, both the rubble of the building and his own fat blinding him. The hose was the only link he had to the outside world, and the only thing that gave away any sense that what he had become was a living beast. He looked to just be a shapeless blob, a collection of rolls and folds of pure fat that was growing feet per minute. The reason for the increased pace of his growth was simple; his stomach had been stretching, and stretching, and stretching some more in order to allow even more of that pudding inside of it. More pudding to digest meant more weight gain, and more weight gain meant more Iron. The canine was fine with this little reality, though, and as he felt that familiar tightness of his body being trapped in yet another room give way, he knew that even more Iron was quite alright by him.

Free of the lab's large building, Iron just spread out like a flattened marshmallow. This spreading freed the debris from his head, letting Iron see again... Even if all that he could see was his own fat and the sky. The brown fur of his chest and cheeks filled his vision nearly completely, only a sliver of sky above them being the outside that Iron could see. That sliver wasn't growing smaller though, the amount of fat that collared Iron's head keeping the rest of his own horizon at bay for the time being. Iron knew that wasn't going to last forever, but even then, he didn't much care about that reality. He was larger than any animal, anthro or otherwise, had managed to be. He could feel houses slowly felling beneath his girth, trees toppling, whole skyscrapers being pushed aside as though they were mere toys... It was a powerful feeling for the coyote and one that he wanted to relish as much as the pudding that had allowed him to reach such a grandiose size.

After all, he was still hungry.
