It had been a long day. Tails wiped his forehead as he made the final touches to his new invention. A lot of time had passed since Tails' adventures with Sonic against Eggman or Doctor Robotnik, or any other adversaries they had battled against. Over the years Tails had matured and focused closely on his inventions not as tools to defeat an enemy, but to enhance his own life. His skills had matured just as he did, and the adult fox had discovered himself along the way, particularly when he became of age.

He was 21 now. Still in contact with Sonic and co., the fox frequently relished showing off his new technology to his friends, but this one was different. His laboratory had grown to the size of a large supermarket, complete with all sorts of gadgets and gizmos he'd invented in the past. This one, however, was the big one. Life-changing. For once, Tails felt like he could really be 'decadent' with this invention.

It took the form of a giant metal compartment in the corner of the lab, with a small opening roughly Tails' size, a few indiscernible dials and lights on the inside, and a rather egregious headline-sign above that read:

"Tails' incredible slave-cloning machine!"

The fox let loose a small chortle, resembling a mad scientist. Usually he was known for being innocent and chirpy, and the latter was still true. He had to admit he was going to try all sorts of things with this cloning device, however. Of course, with Tails discovering himself, he very quickly realised he had a preference for other guys. Liaisons with Sonic and Knuckles had recently brought up feelings he hadn't felt before about them, ones where he would often have to leave for a quick moment to 'calm himself down'; vivid images of them taking advantage of Tails and having their way with him invading his mind. With this cloning machine, he initially planned on exploring himself quite literally.

It was time to test it out. Moving into the machine and tapping a few dials here and there, he set the machine's settings. It already had Tails' DNA inside, so all he had to do now was set the "neurological personality modulator"; he was essentially programming what his own clone would look and act like!

Output: 1 clone

Personality: Loyal

Appearance: Normal

Directive:

He put a hand to his chin. What would be his new "friend's" first objective? He had to test it with something...

Directive: Get Tails a sandwich. Await orders after.

There! That way the clone would obey what Tails said to do after he'd gotten his lunch. What could go wrong?

The door closed as Tails operated the mechanism. With a few mechanical noises, Tails emerged from the machine as steam followed him. It only took about 5 seconds, which the fox seemed enthused about; damn he was efficient!

From the other side of the machine, a similar figure emerged. Tails gasped with his mouth held open. No way, it worked! Tails watched as his clone slowly stumbled out of the machine, then approached him. The "master-fox" as he entitled himself so he wasn't too confused in recordings wasn't sure how to approach the situation. Was there a social decorum here? The clone wasn't saying anything...

"Hello..." Tails said as the clone suddenly walked off and out of the laboratory in an almost robotic-like fashion. Tails stood forward to follow it until it returned holding a plate, true to its orders, with a sandwich on it. Tails took it and munched on it. Yup, just a sandwich. If anything it was pretty good; generous fillings with high quality bread. Tails smiled as he gulped.

"So uh... you follow orders now?" Tails said, finishing his meal. The clone simply nodded silently. "C-can you say anything? You're weirding me out here..."

"I can."

This was incredible. The device worked! Tails felt a sudden rush of excitement as he realised the extraordinary power he had just imbued himself with.

"Ok! I'm gonna keep testing this, what do I say now?"

"Do you want me to do anything, or is my purpose complete?" The clone responded with a monotonous manner.

"Y-your purpose is complete now I'd say..." Tails responded. The clone lit up, smiling briefly at its master before it disappeared with a blinding light, and Tails was left alone in his lab again with more questions than answers. First thing's first, he'd make sure he'd specify more on the personality function, he was unsure about having soul-less slaves, but then considered his options. He couldn't just have them do whatever he wanted, he could literally decide on their personalities! There'd be other versions of him with all sorts of personal tropes, yet they'd still have to obey him since he operated the machine! He smiled impishly to himself. The possibilities were endless...

A few hours had passed as Tails wrote out a few reminders on what to consider for his next few settings. It was late. So late that any neighbours were asleep, and he was left alone. Suddenly the familiar feeling of being able to take advantage of his solace came as he felt a rush between his hips. Tails was particularly virile, and wasn't afraid to satisfy any urges he had right there and then. Sitting in his lab, he watched between his legs as his member slowly grew and pulsed. In his mind he had images of guys. Fantasies with Sonic and Knuckles, fantasies with much bigger guys than him having their way, fantasies with...

"Wait!"

Tails looked at his new toy, and grinned. His cock twitched as he reached full size, 6 inches of pulsing fox meat between his legs. "Whatever I want..." He said underneath his breath as he stepped back into the machine, playing with some of the settings.

Output: 1 clone

Personality: Submissive

Tails then shrugged. Who was he kidding, thinking about himself being taken caused his cock to stand rigidly to attention.

Personality: Dominant, Horny

The fox let out a few moans typing that out. No-one was going to stop him from doing this.

Appearance: Normal

Wait no! He was going to do whatever he wanted, and test this machine at the same time! Panting nervously, he returned back to the controls, resetting everything.

Output: 1 clone

Personality: Dominant, Horny

Appearance: Increase cock size 200%

Objective: Fuck Tails

The fox was ridiculously horny now as the door closed, stroking himself eagerly. He emerged, awaiting his new fuck-buddy, who came out the other side and greeted him.

"So you're the one looking to help me with this thing, huh?" This clone had a lot more personality, but more noticeably, a massive, throbbing cock 12 inches long and proportionately thick. Tails stared at his own clone, that huge thing between his legs! He could only moan as the clone approached him, his mischievous face and foxy demeanour so ready to ravish his 'creator'.

"Ok master, raise those tails for me, I feel like I could blow any second!"

Tails willingly did so, breathing heavily and moaning as he placed his hands on a nearby table. He lifted his rump and exposed himself to the clone and his huge endowments. Staring back, the clone's balls had increased in size too, swaying with each step. Tails stroked himself at the sight of the clone as it lined its massive foxy cock against him. He could feel the tip throbbing underneath his tails as he gasped suddenly.

"I want you to fuck me. I want you to make me the sluttiest fox this world has ever seen!"

With that, Tails felt his ass stretch around the clone's massive cock as it pulsed and twitched deep inside of him. He writhed in pleasure against the desk as the clone continued to press himself further inwards, causing Tails to reach down and violently jerk himself off. He could create absolutely anything to indulge in his perverse pleasures and no-one would know!

He felt the clone grab his hips suddenly and pull him inwards, forcing more cock inside of him. Tails started to gain rhythm, clenching around the clone's massive cock as it grunted, thrusting aggressively. Pre spurted copiously inside the slutty fox as Tails felt his internals flood warmly with it. The clone was fucking him with his entire length now as his huge, heavy balls slapped against Tails'.

"Y-yes! Fuck me harder! Make me your own personal slut! Cum inside of me!"

The clone simply gritted his teeth and started thrusting his massive endowment into Tails all the way to the hilt as the spurts of pre grew more frequent and copious with each hump. Tails clutched onto his gut as he suddenly jerked with pleasure, howling loudly. He felt his belly fill with warmth as the clone started cumming. It didn't feel like Tails' usual load, this had MUCH more volume to it.

"K-keep going! Fill me up!"

Tails only encouraged the clone as it let loose spurt after massive spurt into him. In response, Tails only clenched his ass around the massive, erupting cock as he continued to fill with his own seed. Tails looked down at himself as his tummy started to bulge slightly. This was getting out of hand, yet Tails felt a sudden sensation for even more.

"MORE!"

He simply yelled as his belly continued to round outwards. The clone was so well endowed that Tails was starting to inflate a little, his mid section continuing to expand as the clone panted heavily. Tails' gut must have surged at least a full foot in front of him when the clone eventually tapered off and removed his huge member from the greedy fox.

"Oh f-fuck..." Tails said, laying down on his back as the clone stared over him. He rubbed his belly, something about it being this big and soft had a big impact on him. Was it that he enjoyed being bigger? Perhaps a testament on how he was always the sidekick? This was all just psychological fetish-crazed nonsense of course, but one thing was for sure, Tails liked it.

"B-before I dismiss you... c-could you tell me how big I am compared to before?". Ordinarily this would be an odd request, but of course, the clone was designed to obey everything.

"Hehe, you're certainly looking a lot rounder now that I'm done with you, Tails..." The clone teased as Tails stroked himself eagerly, lying on the floor and patting his bloated tummy. Each stroke caused a ripple across his expanded mid-section.

"Goodness, look at you! It's like you've had a hundred of those sandwiches!" The clone said, jiggling Tails' gut as the fox's breathing grew short and loud. "You keep taking cock like this and you'll be enormous! Knowing you, you'd like that. Bigger cocks, bigger Tails, are you ever gonna stop?!" The teasing was too much, the clone knew exactly which buttons to press as Tails' mind went into overload with hidden fantasies he never knew he had.

"D-DISMISS! FUCK!" he said as the clone evaporated just as the last did. Tails thrusted against himself as he jerked off, coating his bloated belly in fox-seed. He always knew he'd be submissive, but this was something entirely different altogether. Never before had Tails orgasmed this hard, and as he let loose a few more eager spurts, he was eager to feel it again. Sitting up against a nearby wall, he took time to play with his newly swollen gut a few times, moaning loudly in the lab as he lifted it and dropped it, admiring his increased bulk.

"W-whatever I want..." Tails said, rubbing his belly, imagining it even bigger. He was a lot more perverted than he thought, and now he had the tools to really enable his kinks. He fell asleep as it was late, fully engaged with what he might do to himself, or rather, have clones do to him, tomorrow...

The next day approached and Tails woke up eagerly. Everyone else was either off on some sort of adventure or busy, leaving the fox completely to his own devices for the entire day. He could do whatever he wanted with it, especially considering he could summon an obedient helper or two at will. Any good scientist would at LEAST muck around with his new invention...

He'd keep the objective for his next clone the same. More than anything, he wanted to see what changing the personality to different options would do. Time to get creative...

Output: 1 clone

Personality: Mischievous

Appearance: Normal

Directive: Get Tails 4 sandwiches

Tails giggled. Perhaps he was getting into a dangerous area by selecting that personality, but he needed to see what would happen. The 4 sandwiches was simple greed; Tails had rounded out a little due to recent events, his slightly bigger belly was evidence of that. He'd done his part for so many adventures, he could treat himself. Besides, no-one would know...

Eventually the clone emerged just as before, and approached Tails willingly.

"So your directive is-"

"Yup, I know, get you sandwiches, I get it..." the clone responded in a tongue-in-cheek tone. Perhaps 'mischievous' was ONE way to describe this clone. At least he was responsive to orders.

Eventually, while Tails was working on something unimportant in the lab, the clone came back offering the fox a plate. Something was off. The bread was much larger than he was used to, and absolutely stuffed with a range of fillings. Tails gave the clone a weird look, taking a bite from one of the sandwiches as his eyes lit up. It had all sorts of spices and meats and other fillings that he didn't mind the difference! Munching up the rest of it, he realised it was a lot more dense, much larger than he expected.

"I made it just for you, Tails!" The clone grinned widely.

"B-but why so big? Why so much? This is too much for me..."

"Too much for a brilliant scientist like you?" the clone teased. "Let's face it, you're a sidekick to cocky companions who walk over you like a doormat!"

That was a bit harsh.

"Well you don't have to-"

"Maybe, but look at that tummy of yours. So round, you've put it on recently, it shows. So why not SPOIL yourself? I saw your face light up when I brought in your meal, I saw it light up again while you were eating. Maybe I did make the sandwich a lot bigger, and maybe it's a bit big of a meal for you..." The clone gleamed as he stared at Tails' bloated belly and rubbed it. "But you deserve it. You programmed me yourself, I'm here to play pranks and be silly, you know that. And I think I want to enable you into spoiling yourself as my prank..."

The clone, as weird and seemingly perverse as he was being, had somehow managed to zero in on Tails' deepest inner thoughts. The fact that he felt underneath sonic and the others, the fact that he felt like he deserved more, those were internal. It was natural for his own clone to know about that. What struck him as odd was that the clone was teasing on his apparent thing for fat. Perhaps it was all those years of being called "little guy" by friends, or perhaps he just wanted to indulge, but having his own apparition tell him that this was ok and in fact what he deserved was having an effect.

Tails moved onto the second sandwich.

"See? No-one else around here but you and me. And you CREATED me because you wanted to see what I would do. Look at that tummy, I know a quick way to sort out being called "little guy" for a start."

Tails continued to eat, stuffing more of the sandwich into his maw. He couldn't help it. He DID deserve to indulge himself, he worked hard!

"You know what strikes me as brilliant? You've got your meal, and you haven't even dismissed me! Look, you're already on the 3rd sandwich! What a fatty fox, keep it going, keep eating! I think you LIKE being enabled..." The clone encouraged as Tails let out a soft whimper.

Perhaps 'mischievous' was a risky option after all. Not a single word the clone said was untrue as Tails continued to eat himself into a gluttonous stupor. He could feel that round white tummy of his continue to swell as he ate and ate. Each sandwich was roughly the size of his head, so it was no wonder they were having an effect on his waistline. The portly fox no longer resembled his old self, rather a much pudgier, rounder version as he ate halfway through the fourth and final sandwich. His belly splayed out a further foot in front of him as his rear comfortably filled out his lab chair. Tails was fairly round, his chest puffing out slightly to form foxy moobs, his belly bulging forwards.

"I may have also made sure those were quite calorific. Hey, we've talked, we both know you like this."

As Tails finished the final sandwich and patted his now substantially large white belly, he couldn't deny it. He looked up towards the clone and smiled as he felt his belly jiggle with each pat and slap. Tails was fat, all within a day with a "mischievous clone". Just as he opened his mouth to dismiss the clone, he was interrupted.

"Ah ah, don't dismiss me yet, let me say this. At least save my personality, you know how. Summon me back, because you're gonna want to." The clone winked as Tails eventually dismissed him, and just like that, the clone was gone, leaving Tails to play with his big, soft, bloated tummy.

He stood up and looked in the mirror. Hefting his gut up, he dropped it, causing it to wobble slightly as he swayed left and right. He huffed a couple of times, not with exhaustion, but with excitement. The clone was right. He DID like being bigger. Inspecting his chunkier arms and legs, his bulbous rump, his soft white moobs, every part of him was larger than before. Clearly the clone must've put something in that sandwich to make Tails this big, but he didn't mind. In fact, he loved it. Perhaps he would summon the clone again...

Tails slept more comfortably than he ever had before that night. While his bed was spacious, it was more likely the extra bulk and fluff that he had packed on that contributed to it. He felt so soft, lying there, patting his tummy and feeling it jiggle, turning to do the same with his butt. He found that the covers often struggled to cover his fatter form, but this only made him grin. Those enabling words echoed in the fox's mind over and over; it was ok to eat so much, no-one had to know, he was enjoying getting fat...

If Sonic could see him now, Tails thought, he'd definitely have some comments about the way Tails' gut swayed with each step, and sagged past his knees when he was sitting down. Tails wasn't ashamed in the slightest. The clone had successfully awoken some sort of fattening obsession within the fox. Grinning widely to himself in his sleep, he dreamt of binging just to see himself get even bigger. He moaned as under the sheets, he humped gently against his belly, getting erect at the idea of completely letting his gluttony get the better of him and becoming too fat to do anything but sit and eat even more. His cock bulged as images of himself getting too heavy for his lab chair and breaking it caused him to groan loudly in his sleep. The sounds of the bed creaking underneath him only further displayed how much weight he had gained, and caused him to grow hornier as he ended up letting loose small amounts of pre against his underbelly. Tails needed more.

The next day, Tails woke up with a new outlook on himself. Breakfast took almost an hour to make, and half that to eat it all. He'd made dozens of sausages, piles of bacon that towered over him as he ate, huge stacks of pancakes sodden with syrup that he'd previously not be able to manage, but the fox sat there and ate. And ate and ate. He couldn't help it, the clone had gotten to him. The entire time he was eating, he'd quietly whisper statements to himself like

"I DO deserve this."

"I can get as big as I like!"

"I need more, and there's no-one around to stop me from eating more!"

Of course it didn't help that Tails' libido had increased tenfold after becoming so greedy and obese; every bite he took from his meal was met with more humps, bucking his chunky hips against his own mass as he felt that familiar feeling of feeling full, then still going. All those calories were going to go somewhere, was it gonna be his moobs? His ass? His huge belly? Gritting his teeth, he leaked against the floor as he humped harder just to feel himself wobble. His cock felt like it was going to explode with how horny he was making himself.

Tails had always weighed around 44lbs during his adventures with Sonic (or at least that's what the mystical 4th-wall breaking scribes of the internet stated) but he got the feeling that this was likely going to be different now, especially after watching himself bloat larger with each passing minute of his tremendous breakfast. The fox eventually finished, admiring the stacks of plates he'd previously devoured, and patted one of his moobs, which had now grown to the size of grape-fruits. Making his way to a set of scales he previously set up in the lab, he realised quickly that he had trouble seeing past his own belly. It took quite a bit of effort, but smooshing against himself and leaning over past his bulk eventually gave him the ability to read "150lbs"!.

"I've... TRIPLED IN WEIGHT?!" Tails exclaimed, echoing through the lab. This was absurd! The more the fox thought about it though, the more explanations he thought of. The scale couldn't be wrong, if anything it made sense considering Tails had supersized to the point where his belly reached 3 feet in front of him and sagged past his knees, his rump only marginally smaller behind him. Could the clone have spiked him with a metabolism slower? Or maybe an appetite enhancer? Or was his newfound obsession with being huge and soft so significant that he hadn't even realised the toll it was taking on his body? Blushing a little as he rubbed himself all over, one thing was for certain.

He liked it. A lot.

Tails imagined himself on those scales as they rose day by day. He imagined becoming so enormously obese that the scales broke. So fat that he'd need industrial vehicular scales to weigh his many tons and tell him how much of a fat-ass he was letting himself become. Again Tails started humping his own mass, but this time he'd gone too far with his fantasies, he needed to release.

"I'm gonna be so fat I won't be able to move!"

Tails spoke to himself as his cock was enveloped underneath his belly, his soft flab massaging his junk as he panted and puffed. He was at full size now, gritting his teeth once more as each thrust against himself caused every curve and roll on his body to wobble in rhythm with his movements.

"Then I'll eat even more! I'll be the biggest, fattest fox on this island! On this PLANET!"

Puddles of pre were forming in front of him as the fox's cock spurted against his underbelly and onto the floor. He hadn't been this pent up in a very long time, and the additional feeling of his bulk moving in momentum with his thrusts wasn't helping. Tails' balls felt swollen as his arousal peaked.

"I'll eat everything I can! I'll have everything within miles stuffed into my maw just to make me FATTER! SEXIER! MORE, I WANT TO EAT!"

With that, Tails jerked his head back, his double chin jiggling as he let loose thick spurts of fox cum against the wall in front of him. His belly continued to rub against his cock as he couldn't seem to stop, the mess pooling up as this was the most powerful climax he'd ever had before. The feeling of his curves jostling about him only worsened his need to release as he eventually tapered off, huffing, exhausted with the energy he exerted in pleasuring himself. Tails' kink was getting out of control, and there was no-one around to stop him from turning himself into a blimp of a fox.

The day proceeded with Tails making the usual adjustments to his inventions. All sorts of machines needed maintenance, and a few experiments here and there needed tending to. The difference today was that Tails was having trouble reaching over himself. Literally, his belly was so big he'd have trouble reaching over tables without knocking them over. He'd frequently move past furniture accidentally knocking it with his big round hips, and any maintenance that required crouching or sitting was met with the struggle of dealing with his gigantic rump, which cushioned anywhere he sat at the cost of him being unable to fit himself under spaces he usually would be able to fit through. Tails wasn't bothered in the slightest. Instead, he anxiously laughed at how ready he was to fatten himself up even further.

It was lunch time. Well, really it was only 10:30am, but Tails' gut growled loudly enough that he knew his next meal was coming regardless of what time it was. He was hungrier than ever.

Picturing himself in the kitchen and preparing food was met with clumsy images of him again accidentally knocking things over with his bulk and struggling to reach over his new mass. He was either too lazy to make anything, or simply indulged in the idea of being too fat to be able to. That's when Tails turned his head over to the cloning machine.

"I really shouldn't..." he whispered to himself, remembering the "mischief" the clone had with his body. Tails couldn't resist. He needed to feel that enabling again. He wanted to be fattened up. Heading over to the machine, Tails input the details he wanted.

Output: 1 clone

Personality: Mischievous

Appearance: Normal weight

If anything, Tails was going to make sure HE was the fattest in the lab. He revelled in the idea of having his body blimped and worshipped by like-minded foxes, who only wanted him bigger. He got a little too excited and typed the next part.

Objective: Increase Tails' weight.

Tails was no longer just hungry, he was eager to be fattened up. He wanted to grow heavier.

The clone emerged from the machine, like Tails but with that same cocky smirk he was so fond of. It feigned surprise at Tails' body as it gasped loudly.

"Hehe, look at you! Looks like I rubbed off on you, huh? Have you been gaining without me?"

The clone leant forward and rubbed his gut as Tails let out a soft moan. It felt amazing being this size. He was so soft, and the attention to his belly was only highlighting that.

"Aww, fatty foxy, enjoying your belly rubs? I'm glad you brought me back, this thing here is still far too small..." The clone said, hefting Tails' gut up and dropping it, causing the fatty fox to jiggle.

Barely a minute had passed before the clone returned with a wide grin on his face and a platter comically stacked with at least 30 burgers. Tails previously left all the ingredients out for the clone to prepare, and with the experimental instruments he had, it took barely any time to create some sumptuous looking burgers. As expected, the scent caused Tails' gut to growl monstrously, to which the clone only narrowed his eyes.

"Two days. Two days since you started this, and already you're huge and too greedy to stop yourself. Heh, I wonder when you're gonna need me around permanently to keep that belly filled..."

Tails simply held his maw open expectantly.

"F-feed me, I don't just want to be full, I want to be FAT!"

The clone simply obliged.

This time there were no doubts or hesitations. Tails simply stuffed as much as he could into his gullet, accompanied with moans and plenty of belly rubs. The burgers, much like the sandwiches, had been supersized to the size of Tails' head each. Of course, this barely stopped the greedy fox from glutting himself. Once more, Tails pressed his paws into his oversized gut and massaged it, feeling that familiar bloating once more. This time, however, his weight gain was much more rapid.

Tails' belly continued to grow outwards in every direction as it pressed against his legs, covering them in soft, foxy flab. His rear was now enveloping the chair entirely as its metal legs started to bend. The screeching of metal buckling to his weight was music to his ears as the clone forced more burgers into his maw. Only five had made their way down to his gullet and Tails already weighed 400lbs. His weight gain was getting out of hand, but he was too into it to care. Clearly the clone was enjoying this too...

"Thaaat's a good fox, you're still way to thin, right? Would Sonic want you to eat this much? Of course not! But he's not here. You can eat and eat and eat. Grow fatter. Grow as fat and huge and immense as you want, there's no-one to stop you from fattening up even more..."

The clone would grope Tails' huge white moobs and plant his entire body into Tails' gut as the fox supersized himself. 500lbs already, and rising rapidly. More and more weight packed onto the fox as his clone continued to tease and grope and rub. Moving around Tails, he gave the fox's massive rear a slap just to see the rest of his body wobble and for Tails to groan.

Tails was now so fat that he didn't even realise the chair he previously sat on was crushed and lodged against his massive butt. He was so immensely greedy that the only thought on his mind was to keep eating and growing, purely enabled by the clone as it kept stuffing more and more into him. His mountainous belly reached the size of a sofa, while his rear behind him followed suit, providing a gigantically soft and yellow cushion for him to sit while he glutted. Only 3 burgers were left as the clone only kept going.

"Man, you must be at half a ton by now! Are you ever gonna stop eating, Tails?"

Tails simply shook his head, immersed within his chins and neck rolls. The clone shoved the third last burger as he watched Tails' body blimp further, his moobs resting atop his belly like over-inflated water balloons.

"And it's a REAL shame that we're running out here, the scientific part of me wants to see just how IMMENSE you'd let yourself get. I'm willing to bet there's literally no limit to how many rolls we could put on you..."

As the clone shoved the second last burger into Tails' maw whole, he gulped it down. He had deliberately planned it so that he'd grow so obese he would lack the ability to move, but of course to prevent it from going chaotic, Tails had lined up enough so that the clone would eventually run out. As the clone held the last burger, Tails licked his lips, groping his colossal love handles and wobbling them for the clone's amusement.

"I mean, it'd be a REAL douche-move if I were to slowly drag this burger away with me and attempt to clone it, right?" The clone said with a wink, patting Tails' bulk forcefully.

Uh oh.

Tails sat there, almost half a ton of fox flab, barely recognisable from his former self, more as a gluttonous whale as he watched the clone grin evilly. It walked towards the machine, holding it in his hand. Tails' rolls of fox flab jiggled as he desperately tried to lift his massive body to resist, but simply couldn't. His stubby, thick legs were nowhere near powerful enough to lift that much weight.

"You don't know what you're doing! I'll never be able to stop!"

Tails cried anxiously as a warning to the clone. Of course, this only furthered the clone's intentions. He thought to himself for a solution and did the first thing that came to his head.

"Dismiss! I dismiss you!" he called, his huge cheeks jiggling with the sudden shouting.

By then, the clone had already typed a few keys into the cloning machine.

"Heh, I guess you have gotten a bit slower with all that soft bulk. I programmed it. You can't dismiss me now. It'll just be you, me, and more food than anyone has ever seen in their life!"

Tails could only watch in terror as he held onto his gut. The clone tossed the burger into the machine. The display was partially visible as Tails made out the settings.

Output: 1 clone

Personality: Burger

Despite the seriousness of the situation, Tails snorted at that.

Appearance: Triple size.

The clone was about to slam his fist on the button, before he stopped himself. Selecting the output setting, he hovered his hand over the number-pad.

"More burgers for the growing fox, right?" the clone winked. Tails was about to object before he saw the dial.

"10 burgers. No, 100 burgers! 1000! A million!"

The clone frantically tapped the "0" button over and over until the value overloaded the display. Tails was doomed; there would be a seemingly infinite amount of burgers to glut on. The very idea of the lab being filled with so much junk food caused Tails' gut to growl ferociously enough to rattle the tables nearby.

"See? You NEED more." the clone said, before slamming the main button.

Almost instantly, the door burst open on the metal compartment as a sudden flood of huge burgers started to fill the lab. Tails sat there in his own flabby mass as he watched all of his inventions sink into what appeared to be a sea of the delectable junk food, helpless to be covered in it all himself. The burgers were each the size of one of Tails' gigantic moobs as the machine just kept producing more and more. Millions of burgers invaded the space of his entire facility as Tails stared in horror, already feeling his resistance failing over his gluttony. A loud buzzing was heard as the machine suddenly halted.

"PROCESS STOPPED; PLEASE MAKE ROOM FOR MORE"

"You hear that, fatty? I'd say you better do the same with that gut if you're gonna make it through all this..." the clone snidely remarked.

Tails was helpless. He reached over himself to grab the nearest burger, and instantly took two massive chomps to finish it entirely. It was at that point, as he realised he could binge on literally millions of these, that he lost it completely. Grabbing anything in range of his huge, chubby paws, he'd instantly drag entire burgers into his maw from left and right to binge on. The room echoed with the sound of Tails' constant chewing and gulping as the fox glutted and glutted. Perhaps not immediately visible, Tails' body was blimping out of control underneath the sea of burgers as it slowly rose within view. Already within the past 20 seconds, he'd piled on another 500lbs of flab to his already immense body. Up against his gut was the clone, who was sensually rubbing Tails' expanse as it continued to bloat larger and larger.

That huge white gut continued to expand forwards, foot after foot, as Tails ate more than he ever had in his life; more than a thousand foxes would have ever eaten in their collective lives. Tails was beyond fat, he was truly immense, piling on roll after roll, exceeding 2 tons in weight and showing no signs of stopping. Tails eventually struggled for a number of reasons, mainly his belly which had surged out a good 12 feet in front of him was trouble to reach over, assuming he could see past his gigantic moobs. Reaching behind himself was a problem with his blimp-like rear also. He felt surrounded by his own furry yellow bulk, relishing in the idea that he could possibly even grow so obese. The indulgence was shortly disturbed by the familiar feeling of Tails' gargantuan belly rumbling.

"You sound like you need a hand, there!" the clone quipped, scaling up Tails' expansive waist and placing himself between the fox's huge man-breasts.

"Hey, you know what? Sounds like you need LOTS of hands..."

The clone gave that familiar impish grin that Tails immediately recognised as "oh man, he's going to do something to fatten me up even further". This time it wasn't met with anxiety or worry, he whimpered excitedly at the idea of the clone finding new ways to enable Tails to grow further into extreme obesity. Tails' eyes widened as "Lots of hands" suddenly made sense, understanding what was about to happen next.

With a few authoritative steps, the clone input some commands into the machine once again, but this time walked into the machine himself. Turning around as the door closed, it winked back at the gargantuan fox, as if to say he'd seen nothing yet. Tails took the moment alone to give his rolls a quick few gropes, relishing in his soft, doughy expanse. The door opened, and out came the clone. Then another. Then another.

It was a sight akin to a furry 'Sorcerer's Apprentice', several versions of Tails strolling out of that machine, each one giggling evilly amongst themselves as they approached and surrounded the fluffy beached whale that Tails had turned into. Tails could only gawk past his flabby chins and appendages as the familiar sight of twin tails flailing around his body could only mean one thing. He was going to get even fatter. He literally had an army of like-minded feeders, hell-bent on making sure Tails glutted and gorged on anything and everything. Not only that, but they seemingly had an infinite source of food. Tails could only stare in amazement, saying goodbye to any semblance of weighing less than two tons for the foreseeable future.

One of the clones clambered Tails' huge white belly, grunting with effort as he eventually placed himself between those great big moobs.

"I'm the one who cloned myself. Y'know, just for reference." Tails stared closely at his face, noticing he was wearing a metal ring. "Guess who's commanding all of these guys..."

Tails simply nodded, relishing in the feeling of his neck rolls jiggling.

"Alright, everyone! Feed this fat-ass! Feed him until he looks like he's gonna explode, then DOUBLE his food in-take! I want him outgrowing this lab within the day!"

Tails eyed the master-clone up, noticing a very clear arousal not just with his tone, but between his legs. The familiar sight of pink throbbing and growing from the clone's sheath caused Tails to pant excitedly. The master-clone had no semblance of shame whatsoever; if anything, he was showing off his junk to the gigantic fatty.

"Getting excited, fat-ass? Maybe we'll make you a big fat fox-slut too..."

The clone grunted as his knot had already formed, passionately groping Tails' seemingly endless rolls as his cock throbbed to full mass. Tails couldn't deny it, he was definitely feeling similarly pent up underneath all of that flab.

"Y-you're gonna make me too fat for this place! I'll-"

Tails' clause was immediately interrupted by a sudden barrage of brownies, as one of the clones had obtained a party-sized platter and recklessly shoved it into Tails' gaping maw. All of those calories were instantly consumed by Tails, who gulped it regardless of what it was. His eyes lulled as the taste hit him like a truck, already feeling glutted as the next clone approached with an even larger platter. The master-clone simply stared on as Tails was immersed with hundreds of thousands of calories in the space of a minute. He was stroking himself aggressively, massaging his knot with his fingers, squeezing his length at the sight of Tails as he ate and ate. Pre-dripped on the mountainous fox's fur as some of the other clones started to grow aroused at the multiplying rolls of flab Tails was developing.

"That's it! Keep eating, we're going to make you eat like an elephant! A fat whale! A mountainous GOD of gluttony! You'll be a landmark when we're done with you, and then we'll clone ourselves a thousand times over to keep up with your appetite! Keep stuffing yourself, keep eating, keep FATTENING UP!"

Tails could only continue to blimp with more and more weight, the clones lining up to scale his huge body and feed him even more. His belly gurgled threateningly as it swelled, the fox it was attached to forcing it to grow faster than ever. It pressed down against the lab floor, so heavy it warped some of the floors' tiles with its many tons of blubber. Tails' rear had now widened to the point where it could easily serve as a bed for half of his feeder army, quickly expanding over more and more of his lab. Tails was eating himself into a gluttonous stupor, fully embracing his new title as a gluttonous vulpine god. Technology and lab implements were bent, crushed and knocked over as Tails' weight gain continued to grow more rapidly. The sounds of his experiments clattering against the floor and screeching as they were bent out of shape by his gigantic fox rump only caused him to have more thoughts of avarice, his vocabulary reduced to a series of greedy moans and cries for more.

He'd swollen to 20 tons now, barely recognisable as a fox, or any normal creature for that matter. Instead he represented some sort of monstrous, expanding, blubberous being that continued to envelop his warehouse with his encroaching flab. The clones had become efficient in the arduous process of over-stuffing Tails, some of them cloning food for the expanding fox, some simply passing food up his gigantic fatty rolls, while others had perfected the process of scaling that enormous belly and feeding it all into the bottomless pit of Tails' gullet.

With every platter, every funnel, every barrel of drink Tails took in, he grew even further. The master-clone was amazed at the sight of Tails' cheeks as they bulged to the size of sofas themselves any time a clone stuffed food into his maw, before he effortlessly gulped it all down, only adding to his furry mass further. "G-god, look at what we're doing to you! You're actually starting to out-fatten this entire lab!"

"FEEDERS, STOP! We need to enjoy ourselves!" The clone said, interrupting the fattening fox clones. The master-clone's cock was pulsing, anxious for attention, dripping pre all over Tails' bloated moobs as he panted desperately. Tails simply looked up at the the clone's member as it loomed over him.

Something inside Tails needed release. Of course, it didn't help that his own cock had been engorged within his flab and was desperate for attention. Many of the other clones had stopped, the ones massaging Tails' body had similarly grown too horny to think rationally. A sudden gasp elicited from the massively obese fox as he felt his many rolls wobble and jiggle; several protrusions being inserted into him. The clones were fucking his folds! This only charged his libido further as Tails looked up at the master-clone, winked, and opened his massive maw. With that, the master clone arched his back over Tails' face, and pointed his needy cock into the greedy fox's mouth.

At this point it was almost instinctual. Tails instantly got to work pleasuring the master clone's cock, so practised with taking vast amounts into his maw that pleasuring the master clone was easy. He used his thick, greedy tongue to wrap around the clone's shaft, giving muffled moans as he could already taste his own pre. The clone simply responded by moaning and thrusting against Tails' maw, which he willingly received, sucking gently and teasing his clone's impressive knot. With Tails' arousal built up with being so monstrously fat, combined with the apparent gluttony for more of that taste, Tails willingly let himself be taken advantage of by the clone and his army of feeders, teasing with his many chins.

Around Tails' body, the clones that weren't fucking Tails where they could had soon joined in. Every single clone had found a fold to fuck. Three of them were taking turns inserting their cocks into Tails' cavernous belly button, the feeling of those tons against their erections too much to handle as they fucked even harder. The jiggling sensation of Tails' blubber only further teased the others including Tails himself as their foxy moans echoed throughout the laboratory.

Several of the clones lined up to take advantage of the world's fattest fox ass as Tails felt many of them invading between his gargantuan cheeks. In response, Tails simply threw his head back with pleasure as he sucked, lifting his comparatively tiny tails to give the clones access to his ass-hole, which he submissively puckered, ready to receive all of their cocks. He could feel himself stretching around the clone's members as they willingly fucked Tails from behind, taking turns, often having more than one inserting themselves into him. The feeling of so many of the clones fucking Tails was causing his libido to build as underneath his enormous belly. His own cock stirred to attention.

The weight gain had apparently contributed to his girth, as a couple of the clones had discovered after hefting Tails' belly up with a jack. At least 3 feet of thick, engorged fox cock bulged anxiously, ready to be teased and massaged. Tails let out another sudden gasp as he felt the clones start to jack off his enormous member, letting loose gallons of pre, matting the fur of his under-belly as the obese fox started to suck even harder. The master-clone complied by grabbing the back of Tails' chubby head and forcing his cock further into his face, causing Tails to deep-throat him. Tails didn't hold back, instead he sucked harder, using his heavy tongue to tease the clone's balls.

"F-fuck, I'm gonna blow. Looks like we've created the world's fattest fucking slut. You're taking a hundred cocks right now. A hundred! Is there no end to your greed? You're just gonna keep fattening up and fucking everyone! You'll be the size of a country and EVERYONE will take advantage of that land-mass you call an ass, won't you?!"

If all the attention from his feeder army wasn't enough, those words would definitely open the floodgates. The clones that were massaging Tails' gigantic cock were now teasing each other on; one humping against his length as the other sucked as much of the tip as he could. Little did that particular clone know that he was in for a powerful surge of Tails' seed as the huge, fat fox started cumming suddenly, his enormous balls letting loose hundreds of litres of fox cum. The clone felt his belly bloat heavily, resting on it as it swelled before he suddenly let his maw go and used his new mass to massage the head of Tails' swollen cock, causing it to release all over the front of the lab, splashing against the wall and pooling in front of the enormous fox.

At the sight of this, the other clones started letting loose into Tails, too enamoured by the sight of the monstrous, cumming blob that they could no longer hold it in. His belly button, his ass, his maw, they were all instantly filled with his own seed as he willingly teased wherever he could, sucking the master-clone's member and gulping everything down, groping his rolls and jiggling his flab to further tease the clones who were filling his massive ass and godly belly button. The display of sheer lust lasted for several minutes as Tails and his many normal-weighted clones panted desperately, exhausted as the lab was a complete mess of his seed and destruction. With a quick half-hour, the clones had eventually recovered their strength.

"Ready for more, you fat fuck? You know we all want you bigger and sexier for us..."

Tails simply grinned. There was no way he'd be able to turn his head to look behind him, or even see past his heavy, wobbling moobs to see ahead. He took it for granted that soon he'd grow too fat for the lab to accommodate him. He didn't even care, his only thought process at this point being "more". He was no longer a scientist and companion to one of the world's most revered heroes. He was a monstrous land-mass capable of emptying any stock-hold the world had in minutes, just to feel the sensation of growing even more obese.

It was then that the master-clone found one of Tails' fattening inventions he'd previously tinkered with. Essentially a metal box with a nozzle that would output food. The input was air, and there certainly seemed to be an abundance of that, along with the abundance of fox-flab.

"Alright, my glorious, feeding army! Take a break, and admire your handy-work!"

The clones panted and puffed, sitting along the walls of the lab; one of the very few spaces unoccupied by Tails. He'd grown so fat that no scale could weigh him; if any of them estimated how many tons he weighed, they'd easily go into thousands. His appendages had sunk into his rolls a good while ago, his tails swallowed up by his house-sized rump. Some of the clones went up to press themselves against Tails' massive, blimped body, admiring the softness as they sank in. Some groped Tails' rolls and hips, satisfied that even they had grown so fat and immense they were too heavy to lift. This all elicited a moan of pure bliss from Tails, the feeling of hundreds of hands massaging his flab indescribable to him. It was then that the master-clone stood before his giant chins.

"Alright, let's make you blow this place up!"

Forcefully pushing the nozzle into Tails' maw, he barely had to make an effort as Tails simply looked longingly into the clone's eyes, already greedily sucking on that nozzle. The master clone giggled at the display of gluttony, seemingly endless as Tails had already let himself grow so big. Taking off the many warning labels that recommended against any of the higher settings, he simply cranked one of the nozzles to a setting that read "industrial city-strength".

"City-strength, huh? MAYBE this'll be enough to fill you... though I doubt it."

Tails' eyes widened, he suddenly remembered the clean-up he had to do the last time he tested this experiment, many months of dealing with a pile of food that towered over an eighth of the entire town his lab was situated in. Suddenly, the nozzle powerfully blasted triple chocolate fudge into Tails' maw with the force of a fire hydrant. Thanks to Tails' gluttony, very little of it left his maw. The master-clone looked on, giggling. Fudge was a good choice. He felt the fox underneath him rumbling threateningly as Tails' rate of expansion doubled, tripled, quadrupled again and again, his immensity already pressing against the walls of the lab.

The ground rumbled, causing some of the clones to lose their balance and fall, pressed against the floors and walls of the lab by Tails' soft expanse. Tails could only sit immersed in flab, and gulp. He didn't want to stop fattening up. Glp...glp...glp... Some of the clones were evacuating to little avail as they couldn't outrun Tails' blimping figure. As the master-clone bumped his head against the roof, it suddenly became apparent just how strong the walls were to him, and just how little Tails cared about anything else but eating. For the first time, the master-clone was starting to feel apprehensive.

"O-ok, you can stop now big-guy, here let me help!"

He went for the device in Tails' maw, before realising his legs were stuck between the roof and between Tails' enormous moobs. He couldn't release himself as Tails continued to eat and eat and eat, looking mischievously into the master-clone's face. He wanted a fox the size of a mountain, and he was going to get one.

"W-wait, you're getting too fat, Tails! Y-you need to stop eating, wait until we get something ready! Y-you're blimping too much! You're eating way too much! YOU'RE GETTING TOO FAT!"

The lab itself would have been blaring with flashing red warning lights and sirens had Tails not grown so big to the point where his fat easily muffled them all. Pressure was rising as Tails continued to gain more and more weight, the walls continuing to contain it all. Something had to give, and the gigantic fox was determined it wasn't going to be him. Minutes had passed as the fox grew heavier and denser. Beneath one of his gigantic hips, one of the crushed panels lit up with "structural integrity compromised" warnings, letting out a loud, high pitched beep. It was incredibly faint under several hundred tons of fox, but Tails eventually flicked an ear as he heard it. This was it. He'd let himself become so gigantically gluttonous that he was willingly eating to destroy everything he'd created, and he loved it. He loved the idea of bursting through these walls to give himself more room to grow and fatten. He needed to feel the cold air against his expanse, just to let everyone see just how massive he was making himself.

As the walls began to bulge from the outside, cracking noises growing louder, Tails breathed heavily through his nose. He. Needed. MORE.

The few clones that had fortunately managed to escape the lab were treated with perhaps the supreme event of Tails' gluttony. Some breaches in the walls had caused bricks to fly far into the distance, bulging with orange and white fur. As more breaches and holes were created, the ground surrounding Tails' lab began to rumble and quake, before what could only be described as an explosion of fox flab took place within a half-mile radius. Tails' many rolls suddenly blimped outwards for hundreds of yards as his body was finally released from the confines of those walls, allowing his immense rolls of flab to finally retain their growth and cover a land-mass that could be seen from all over town. Amenities, buildings and parks were effortlessly flattened by the gluttonous fox as the sudden feeling of his release caused him to lose control and belch loudly and forcefully enough for the feeding machine to propel itself between his moobs and get stuck between them, stopping itself.

Tails was obese. He was colossal. There were very few words that would accurately describe just how immensely fat Tails had let himself become. Many residents of the neighbouring town had left their front doors to gaze at the mysterious expanse of orange and white fur that loomed in the distance and caused vibrations in the ground so powerful that they could feel it.

Tails couldn't move. With cheeks like blubbery, furry beds and neck rolls to match, there was very little he could see that wasn't himself. To him it looked like a sea of white fur that expanded endlessly. Eventually the clone emerged from his landmass, gently patting Tails behind the ears.

"You know what? You could dismiss me now, I feel like I've accomplished what I wanted. That is... unless you're still feeling hungry?"

Tails narrowed his eyes in response. The clone didn't even have to ask what his answer was. Getting ready to get Tails more food, he simply grinned.
