Everything was quiet; bedrooms were empty, furniture lay untouched, and not a single person stirred besides a middle-aged fox. Having the entire house to himself felt odd to Miles Prower, who'd spent the last few decades raising his children and being a devoted husband to his wife, Mina. The routine that he'd followed all those years had only recently been broken, and it left him with a ton of free time that he didn't know how to fill, at first.

He'd grown used to having his children around and seeing them move out and head off to school struck him hard, feeling the effects of the empty nest almost immediately. It took a little while for him and his wife to adjust to the change, but they still had each other, and that was more than enough to get them by.

They spent their time hopelessly devoted to one another, doing everything together that they didn't have the time to do with their kids around; it kept the pair of them active as they aged. And then one day his wife received an invitation from some friends to go on a vacation for a month. Initially hesitant, she was ready to decline before he convinced her to go and have fun by saying that he'd be fine. She left yesterday, making this the first time in a long time that he was by himself, and there was only one thing on his mind that he wanted to do above everything else - start work on his inventions again.

It'd been ages since he last had the opportunity to tinker with the stuff in his large workspace. Sure, he worked on the odd creation here and there, but nothing really worth talking about - nothing that really got his brain going, nothing big.

And it was in his work station where Miles had the components ready to go for an idea that he'd had for years. In his youth he'd stumbled across the concept that matter cannot be created nor destroyed, merely converted from one form into another. There were plenty of natural examples of the phenomenon that he could easily cite - such as the breakfast that he'd eaten earlier in the day - but he wanted to know if he could harness that kind of power. Would he even be possible? The answer to that question was close, he could feel it in his bones.

Diligently he worked, poring over his notes in an attempt to recall where his headspace was when he wrote everything down in the first place. It all made sense to him, though he realized that he'd learned quite a few things related to this idea since the last time that he really got down to working on it. The thought of making it far more efficient than he originally planned for it to be tickled him.

If there was one thing that he could be proud of, it was that he always did an excellent job of preparing his future self for the task of final assembly. As such, even though some of these parts sat for longer than his children had been alive, all they took was a simple dusting before they were operational again.

And just like that the device was complete! He pushed his goggles to the top of his head as he warmly regarded his invention. It was fairly simple in its construction - at least to him - but its purpose could have potentially life-changing effects for everyone across the planet. Baring that it worked properly, of course.

But the machine would only be as good as its interface, which it didn't natively have as it had yet to even be programmed. Fortunately for him he had the layout of a plan in his mind, just needing to implement it on his computer so that he could get this show on the road. There were certainly days that it paid to be a genius.

The large monitor filled with dozens of different windows, all telling Miles something different and all of it being understood. It was fortunate that he'd at least kept up with coding over the years as a way to keep his brain sharp as it meant that this stage was a breeze in comparison to how difficult it could've been.

It had barely been an hour since first walking into his work station but he was ready to test his invention. The hard part now was determining what exactly would be an adequate first experiment, only for his eyes to twinkle with excitement when he happened to glance up at the overhead lights. It was a little rudimentary, but it would be perfect!

The device couldn't select any target automatically - he needed to do that with the software that he just created and download the information into the machine in order for it to work properly. From there it would read the instructions given to it and wirelessly transfer any energy inputted to its destination. That's how it was supposed to work, of course, but it wouldn't necessarily be a guarantee until he actually tried it out.

Now, there were a number of different ways that he could conduct the experiment as there were a number of different forms of energy available to test with. The most basic was a large crank that he could turn to induce motion, though as he wasn't the strongest person around he decided that one success with it was more than enough.

Flicking the switch to his workspace off, he got to work on rotating the apparatus after flicking his red scarf out of the way, his arms burning in spite of how well-lubricated the internal mechanism was. All the while he kept his gaze squarely focused on the lights hanging from the ceiling, sighing in relief when he saw a flickering glow emanate from them. Thank fuck that worked!

The next test was far simpler to conduct given how little he had to exert himself. A sound sensor had been installed into the machine, allowing him to merely clap his gloved hands and produce waves to be converted into energy of a different form with minimal losses. He tried that as well as other methods, such as shouting, stomping his boots on the ground, and clattering his tools on his computer desk, all of which made the bulbs brightly shine before dimming once more. Another success!

The last thing that he wanted to try for the time being was the thermal sensor, able to detect any heat energy nearby it, though for the sake of experimentation he fashioned it into a bar that could be held onto. A few seconds of briskly rubbing his hands together to cause friction was all that was needed, with him grabbing onto the handle and seeing the bulbs glow for a brief moment before dying off again. His twin tails swished behind him in excitement. That one was definitely difficult to maintain for long, but he could clearly see that it was also operational.

After years of it being at the back of his mind, Miles had gone and turned one of his oldest ideas into reality. While he wanted to celebrate his incredible triumph, he realized that he'd tuckered himself out far faster than he anticipated - his former lifestyle wasn't the most high-impact one that he could've lived. That didn't matter as there were other means of input that he could try.

But he figured that a change in target was in order first. It took him a hot second to come up with what exactly, but he thought of something perfect to try out, scrambling to the kitchen and coming back with a half-full pot of water that he set on an insulated table. If this worked, he might not need to drop any money on the stove upgrade that he promised his wife.

All that needed to be done now was adjust the target, which, of course, needed the lights back on in order to see properly. His fingers clacked away at the keys as he reprogrammed the target, though he stopped when the software gave him grief. For whatever reason it fought him when it came time to select a new object, and he grumbled over how he should've tested his code more before trying it out.

Fiddling with the program gave him a headache when it became apparent that it wasn't about to cooperate, him hanging his head and sighing in frustration as his computer froze from what should've been an effortless task. Deliberation about calling it a day and starting again tomorrow vapourized the instant that he saw the software return to normal. What's more was that it actually did what was asked, singling out the pot of water as the target. He didn't know what all _that_was about, but he was glad that it was now over.

Or, was it? Had he paid closer attention, he'd have noticed that the target was composed of more than just water. Many different elements would've populated the screen had he chosen to view additional details of the target, all ones that, when combined, would've taken the shape of a particular middle-aged, twin-tailed fox. He, unfortunately, was oblivious to that fact as he downloaded the new instructions to his invention.

Brimming with eager anticipation, Miles grabbed the device's power cord - currently wrapped around a notch in the back of the case - and tugged it towards a wall outlet. He beamed with zealous glee over seeing another success. If his calculations were correct, the energy being blasted directly into the water itself should heat it up faster than it would by regular means of convection. His excitement was palpable.

Well, it would've been had the water started boiling then and there. Uh, did he make a mistake somewhere in the design of his machine? He couldn't have, considering that it powered the lights without a hitch. As much as it pained him, he might just have to concede that his device didn't work as efficiently as he'd hoped it would. Ah well, the thermometer that he stuck in the water would indicate that at least some heat energy had been induced in the pot.

Only the thermometer didn't measure any difference in temperature at all, much to his supreme confusion. It left him scratching his head, ignorant to the fact that he'd gained a slight definition across his frame that he'd never had before. His creation was actually a smashing success were he aware of it, only instead of heating up a boring pot of water it chemically induced a multitude of changes in his own body.

The biggest of which was that he'd grown musculature that he'd never had before in his life, as his friends and family could attest to. Why would he need it when his calling was in the sciences? There were plenty of people who had being brawny down pat, meaning that he could focus his efforts elsewhere.

But now he looked like he'd actually attempted following in their footsteps. What was once a completely flat chest that he never paid attention to had now become modestly rounded as if he'd spent a couple months lifting weights in a gym, though not insignificant enough to be ignored. Not a single person would overlook it given that it was on him of all people.

And the rest of his body followed suit as well, with his limbs not appearing as noodly as what they used to be. The problem was that none of these changes were enough to catch his eye as his mind was firmly concentrating on his apparent failure. What could be the issue?!

Surely there wasn't a fault in any of the device's components, right? A quick test with his multimeter could disprove that in a jiff. And yet when Miles opened up the side panel where guts of the machine lay, every single test that he could think of all indicated that his invention was fully operational. But how could it be when it literally couldn't do the thing that it asked him to?

There had to be something wrong with it, he just couldn't think of what and it maddened him. Man, he was so close to nailing this idea it burned him how it took only two tests for it to fail. Was it the pot of water itself? Maybe the vessel was inadequate for this application. Maybe water wasn't an acceptable target after all, though his extensive calculations should've rendered that problem impossible. All sorts of similar ideas flashed through his head, never once thinking to check if he'd even selected the right target.

Maybe, for whatever reason, it was just the form of input that didn't work; after all, he didn't initially use electrical energy to turn on the lights. It hurt to think that he somehow messed something as trivial as that up, but he was running out of potential solutions at this rate. He was willing to try anything to end this day on a high note.

So he turned to the methods that he already knew worked, starting by stimulating the thermal sensor, only he'd thought up a much better way to do so for his experimentation. The one device in his house that could produce any sort of thermal energy in an instant was their blow dryer, which he scampered off to retrieve. He found it a little silly that he was using heat to induce heat in the water, but he figured the idea to be brilliant given the incredible output of the dryer.

With a confident smirk, he activated the appliance and held it near the sensor, knowing that he'd start hearing bubbling come from the pot soon enough... only for nothing to happen after nearly half of a minute passed. Both tilting the device towards his fur and giving the handle a light touch indicated that heat had been created. He checked the thermometer again and, sure enough, the temperature was exactly the same as before, maybe even a little bit colder. It boggled his mind that something that worked before didn't now.

Maybe sound would do the trick; yeah, that one easily had the best results with the lights! Snatching some tools from the desk he let them fall to the ground, the noise produced evident to him, however, the water remained as tranquil as ever. His muscled shoulders slumped forward in disbelief. Perhaps more sound was needed? Just about the loudest noise that he could come up with was repeatedly slamming his wrench into a metal garbage can lid, and even that failed to stir the water.

His heart raced in his chest as he scrambled to come up with some explanation as to why his experiment floundered so hard, and he'd have found his answer if he'd only have looked down. Because of the additional input to his machine, the rate of growth in his body jumped slightly, giving him a physique of someone just starting out in a contact sport. And yet he'd gotten so frazzled that he interpreted the tensing of his now thicker musculature as agitation from a lack of results. If only he could realize just how much of a success his invention really was.

Now he was growing desperate; so desperate, in fact, that he genuinely considered using the crank again. Maybe he accidentally utilized faulty sensors and that's why the other inputs weren't working past the first attempt, but the analog nature of the wheel meant that any potential lack of success would be immediately obvious to him. Well, he undoubtedly hoped that was the case.

His eyes still glued to the pot sitting on the table, Miles spun the crank as fast as his arms would allow, which happened to be significantly faster than when he started his testing. He'd grown so focused on making his hypothesis work that he didn't see his own body swell in real time. Every rotation of the wheel pumped another inch onto every measurement across his frame, which in turn created a feedback loop where he turned the crank faster. In his pursuit for scientific greatness the motion had become effortless, fueled by his desire to see--

Hold on, why was cranking the wheel so much easier now? He distinctly remembered having the hardest time trying to make even one revolution, which meant that doing dozens of them without thinking about it struck him as an impossibility, almost like a real-world glitch of sorts. Certainly there must've been something that came loose within the mechanism, it couldn't have been that--

He'd gotten stronger. That wasn't a guess based on his previous lack of success, but a confirmation with his own two eyes, which nearly fell out of their sockets as he observed his frightfully bulging physique. He looked like a goddamn bodybuilder now, completely unbefitting for a scientist of his calibre! His hypothesis that it was a trick of his eyes fell flat when he gripped a flexing bicep, feeling for himself that the solid bunch of muscle was assuredly his. But how?!

His discovery made him pause as he tried to formulate a theory that actually made sense. It wasn't like he went out of his way to grow him bigger - why would he? He'd been fine with his size for decades now, that morning included. It didn't follow any logic that he should suddenly find himself multiple times the fox that he used to be when all he did was perform some experiments.

And that's when he realized that all of this happened because of his device; it had to be as every other variable had been accounted for. But... wait, that still didn't make any sense. He ensured that the pot of water was the target, right?

One look at the software running the device indicated that, no, he was the target the entire time, much to his chagrin. If only he caught the error earlier, then he could've saved himself the massive headache that followed. Oh well, live and learn.

Or not quite; that would only be feasible if he didn't happen to run into the same problem as earlier. For some godforsaken reason his program broke again, the act of trying to switch selections causing it to hang without him able to do anything about it. Seeing the screen frozen in spite of barely having touched his computer got his mouth to scrunch up in frustration, having to wait several agonizing moments before regaining control again.

Miles' fingers flew across the keyboard as he attempted to rectify the problem, however, it appeared that something was fundamentally wrong with the targeting software that he programmed. It forced a frustrated sigh out of him as dealing with the issue wasn't as easy as what he thought it'd be. No matter what he attempted to do, nothing seemed to alleviate his dilemma. His system would require a full reboot as that would ensure that his program would start off fresh again.

But his fixation on the program itself led him to forget one very important detail regarding the device - it held onto whatever target was downloaded into it last, meaning that he would continue having energy pumped into him regardless if his computer was on or not. The problem only grew bigger as the machine was still plugged into the outlet, continually drawing power that he'd forgotten to address. His oversight would become apparent to him soon enough.

At the very least he was able to successfully get the computer to shut down, though only happening after another couple of minutes of attempting to force close the program. He was breathing a little bit easier now that he got his rig cooperating with him again, each breath in particular making his chest rise and fall as it steadily grew bigger.

The constant stream of electricity drawn into the machine kept it continually converting it into chemical energy that his body could use, swelling him out to be the bulkiest vulpine around. Had he the means to inspect himself, he'd see that his back had bloated to a sumptuous degree, on point with certain pinup models that he'd seen on calendars. He honestly had no idea why anyone would want to look the way that they did, but they'd all have been jealous that the canine got to beef up so effortlessly.

Little by little his frame broadened out, the energy pouring into him thickening his musculature well beyond where he'd have ever wanted it to be. Traps that should've been nonexistent now bunched up along his neck, giving him one that a bull would've been proud of. Birds would be envious of the secondary wingspan that his flaring lats gave him, muscles that his basic knowledge of anatomy told him existed as he wouldn't have known that he possessed them before today.

Of course none of that ever crossed his mind as he had far more important things to worry about. The rate in which his computer struggled through his boot cycle worried him as he had no idea as to what exactly could've bogged it down. As unnerving as it would've been, an error message of some kind would've been incredibly helpful at the moment.

Time marched on as his body had other plans, accumulating mass like it's what he was meant to do. His midsection - which he only paid attention to in order to remain lithe enough to fly - had tightened dramatically, giving him abdominals like a perfect cobblestone path. They came with obliques shredded enough to clinch a win at any competition that he would have competed in had he cared about that.

Not wanting to be left behind, Miles' legs also benefited from the growth, swelling up tremendously as they abandoned the stick-like appearance that they used to have. Firm with bulk, they tensed as his agitation mounted, displaying size that he'd gained in mere moments. Quads that only needed to help him get off of the ground now looked like he used them to cycle up the largest of mountains in order to reach the grocery store. This was far more size than necessary that his daily walks required!

And all of this growing came with an unfortunate side effect - it was beginning to feel really good. Try as he might, he couldn't stop himself from grunting as his twin cocks started to come to life, the stimulation of his ballooning heft rubbing against itself starting to feel too good to ignore. He never really considered himself to be all that much of a narcissistic person, so the idea that his own body turned him on like this felt particularly bizarre.

A grunt escaped past his lips as his shafts slithered up his ripped abs, feeling them pulse in sync with one another as even they took advantage of his growth. It was difficult to ignore, though he did try. The last time that he'd even gotten erect like this was ages ago, and his lack of sexual activity had him carefully doubling over his desk as he patiently waited for his computer to boot to the login screen.

He bit his lower lip as the burgeoning feeling persisted in his nether region. Like his endowments, his balls, too, surged as the rest of him grew. They'd been a reliable set of eggs for the entirety of his adult life, though in a matter of moments they'd fattened into a pair of baseballs, only getting bigger the more that time ticked away.

His sexual frustration could be seen in how his two tails spasmed from the intense stimulation coursing through his nervous system. All that he wanted was to maintain composure and hopefully right whatever went wrong with his program, though he had no idea how he could reverse his unbelievable growth. God, this felt way better than it had any right to.

The feeling of his overly sensitive foxhoods throbbing against his swelling abs caused him to pound a fist against his desk, trying his damndest to stay collected and focused on the task at hand. Just about everything that he could think of to alleviate the overwhelming sexual desire pulsing through him had been tried, leaving him bending over as much as he could in order to let his members fall away from his torso due to gravity. He'd be an unsightly mess were anyone around to catch him, making him thank his lucky stars that he was home alone.

Miles gasped and groaned as his expansion continued, now feeling more than just beef being added to his body. In a strange turn of events he felt his frame stretch out, both his shoulders widening as well as his torso getting longer. The sensation flared his nostrils wide, barely able to comprehend the changes happening to him as they did. It felt like he was going through a second puberty, only this was occurring over the course of a few seconds. If only it felt this amazing the first time.

Muscle fibres tore apart and repaired themselves as energy continually pumped into him, his skeleton creaking larger as his computer recognized that something had gone wrong and had begun inspecting its hard drives for damage. Not now! He grunted in annoyance at being locked out of the very thing that could've stopped this from continuing.

And yet it continued, his body piling on muscle mass like it was going out of style. For the first time in his life - or really the first time that he ever saw on someone - his chest had puffed out enough that he could observe it in his peripheral vision. Were he a biologist that could've been an exciting event, but as an inventor it did literally nothing for him but ring alarm bells in his head. Pleasure inundated his very form, coaxing his hands to grip either one of his pillars. It took him everything that he had inside of him not to acquiesce.

In the midst of his growth, there came one side effect that he wouldn't have predicted even if given enough time - every single creak and groan that came from his body fed into his creation's sound sensor, involuntarily feeding back into him and adding to his expansion. It became a vicious cycle of growth, one that he didn't want but his body craved.

He had to get away from his invention if his computer wouldn't load in time. Taking even a few steps was a lot to process as the way that his body undulated against itself sent shivers of ecstasy ripping up his spine. In mere seconds he had to stop and take a breather, feeling the urge to relieve his pent-up tensions that had built up over years of neglecting his baser needs. Had he known that he'd one day be pummeled with euphoria from a freak accident, he might've prepared himself appropriately.

More and more he surged outward in all directions, now standing a full head over where he did moments ago. His weight had positively skyrocketed thanks to carrying hundreds of pounds of vulpine heft. It took him a second to relax enough to keep composed as his knees just about buckled from his flourishing shafts getting caressed by his shredded torso. Man, he'd never felt so heavy before in his life. How do those other people do this regularly?

Unfortunately for him, the sound sensor that he bought all those years ago was purchased with the intent of being overly sensitive, meaning that it still picked up every single noise that his body produced. Things had only grown worse since he recognized that as every groan from both him and his physique had become longer the bigger that he'd gotten. He fought his hands from shooting to his burgeoning pricks, denying himself the pleasure of feeling up both them and the grapefruit-sized balls that he'd gained as well.

It was only then that Miles realized how much tighter both his boots and gloves had become. It used to be a slight discomfort that he could easily ignore, but now it was noticeably painful how little room there was. He didn't even think about removing them before he got to this point, now he wouldn't have the chance. He just had to watch as both his hands and feet busted out of their respective garments, eventually leaving the fabric in shreds.

Still he continued to grow, his arms being forced away from his sides now. That concerned him more than he thought it would. He looked at one and nearly fainted, seeing that the tricep alone was far thicker than what his waist used to be, with the whole arm itself bloated bigger than a steel bar. His biceps both flexed into split peaks - verified by looking at his other arm - displaying the two heads that he'd never seen show up on another person before. Were this not happening to him, he might've found it fascinating.

And his chest! God, he could really see it now, even without looking down. What would he say to someone if they saw him like this? He genuinely had no clue, and it worried him beyond belief. He had no realistic-sounding answer as to why his pectorals had abruptly grown large enough that he couldn't cup one of them with both hands. Not having answers to questions was one of the things that he hated the most.

More and more his cocks grew, thickening the more that time ticked along. They used to only reach his belly button - more than big enough, in his opinion - before now reaching just under his mighty pec shelf. He didn't even have to touch them for them to pulse pleasure into his system, merely flexing his pelvic muscles felt good enough to elicit preseed to dribble from them. The temptation was strong.

Having barely taken any steps away from his computer, he noticed that he'd have issues operating it even if it had loaded up properly as he'd grown more than a foot taller than when he woke up that day. He groaned in frustration that his expansion had picked up so much, forcing him into increasingly uncomfortable positions just to try and ignore it. It pained him how much more frustrating it'd be trying to fix this mess now.

He needed to widen his stance, not because his tree-trunk legs fought for any and all space between them, but because the fact that they touched at all caused his vast musculature to spasm uncontrollably. His inner thighs were aggressively sensitive, something that they'd always been but had since intensified upon growing.

The fact that he had so many issues simply standing made him wonder if letting himself fall to his knees was a better alternative, but he quickly dismissed the idea when he realized that it ultimately wouldn't solve anything. Pleasure felt good no matter where it came from.

Ugh, was it getting hotter in there or was it just him? Normally he had the window open to let any warm air out, but he'd forgotten to do so in the midst of his testing. What was causing it though? His device produced minimal heat at best, and his computer hadn't been on long enough to cause those sorts of problems. That made him realize that he must be expending heat at a tremendous rate; the thought made him panic as he recognized then and there what that really meant.

All of the excess thermal energy that Miles gave off activated the heat sensor, which only just stuffed him further with densely-packed muscle mass. In seconds his rate of expansion surged, pushing the bounds of his blimping stature far beyond what he thought a Mobian was capable of. Maybe if he could just stop the device himself...

Nope, not gonna happen - even moving an inch felt too damn good to ignore. His best bet at the moment was to sit tight and wait for his computer to finish the boot cycle and possibly hope that he could muscle through the euphoric bliss enough to halt his impossible growth. That was honestly the best plan that he could come up with, and it scared him given what he'd learned in the short while since having started getting huge.

But he might not even get that shot considering how gigantic he continued swelling. Already two feet taller than where he started, his frame had bulged three times wider than his normal self, his cannonball-like shoulders leading the way. That was true of his thickness as both his chest and back worked together to give him depth that he'd only think was possible in science-fiction. Every time he moved his arm it brushed past a prodigious pectoral, causing him to shudder as his turgid dicks shot more globs of pre out to mat his fur.

All the while the temperature of the enclosed room grew, converting all the thermal energy into pure beef that accrued onto him like his body was addicted to packing on the stuff. As tall as he got, his musculature grew faster, putting his frame to the test by seeing how much mass it could stuff under his pelt before he needed to get even bigger. He wasn't thrilled at becoming an impromptu science experiment.

Already twice as tall as his usual height, Miles could barely believe that such a vantage point was possible without necessary equipment. He shuddered in bliss as his medicine-ball-sized kneeknockers pumped him full of testosterone that only served to fuel his potentially never-ending growth. His orbs audibly churned with potent foxbatter, waiting for the moment in which they could unleash it all, though his arousal swelled along with him, meaning that there was never the chance to cum just yet. The conflicting emotions rushing through his body maddened him severely.

He estimated that, with his inconceivable height, he had to have effortlessly passed a ton in weight by that point, making him comfortably the heaviest person on the planet, if not in existence. He groaned, though wasn't sure if it was in pleasure or irritation at how futile trying to fight his overpowering libido was. The fury of erotic desire welling up inside of him left him far hornier than he was in his sexual prime, which floored him when he considered just how much rope he used to blast on a daily basis in his youth. The fact that he was overtaking the stud that he used to be spoke volumes.

His twin tails swished against his ballooning ass cheeks, neither of them leaving a mark on the dimpled globes no matter how hard they struck them. They'd simply grown far too dense for that to be possible, handily weighing hundreds of pounds apiece and only gaining more as time passed by. He had to be careful that he didn't accidentally sit down on anything as he'd easily crush it beneath his monumental weight, though he could potentially think of some genuine uses for such an ability.

But that'd have to wait as his arousal spiked harder than it ever had previously. Try as he might - and he damn well tried his hardest - he could no longer prevent himself from succumbing to the unrelenting pleasure as it hammered into his very being. It was just too much to handle and he had no choice but to give in.

Immediately he got rocked by euphoria, the slightest fondle of a tremendous pectoral enough to make him moan aloud, causing another quick spurt to hit him. That only pushed his libido even farther, urging him to grope more of his colossal bulk. Fuck it, he'll just get it over with and clear his mind, then get back to finding a solution.

With his titanic traps having practically swallowed his neck, his scarf had grown loose as it clung to whatever muscular crevice that it could find, eventually not wrapping around anything and falling to floor, thankfully unharmed. That left his goggles as the only thing left on his body, though he had no idea for how much longer.

Just thinking of how thick his neck was got Miles to moan again, the loud, rumbling noise flooding him with yet more muscle mass. He'd become trapped in a ceaseless loop, where getting bigger made him get bigger. The thought elicited yet more precum to belch forth from his cocks at the thought of being hit with more pleasure, though his mind knew better. He'd find a way to solve this, he knew that he would.

But that would have to wait as his hands had only just found purchase on his nipples, discovering how great that it felt to tweak them. He twisted the pair of them this way and that, turning them like car radio dials as his grunting only picked up. Did this always feel this good? Maybe his failure that day was a bit of a blessing in disguise as he discovered things about himself that he'd have never considered otherwise.

More and more of his grotesque bulk blimped into itself, sending him reeling with the insane amount of ecstasy coursing through his veins. His sweaty bulk only added to the rising temperature of his work station, the converted energy skyrocketing his size as his exponential acceleration showed no signs of slowing down. Flying may be a bit out of his repertoire at the moment.

And if all of that wasn't enough, his throbbing shafts had been absorbing as much of the energy as they possibly could, surging past his hands and just about into his field of view. They'd become tantalizing in their enormity, each bigger on their own than what ten of his regular-sized body was. The thought titillated him as the pressure in his lower half grew as quickly as he did.

While he'd become focused on letting himself receive all the pleasure given to him, it wasn't like he'd suddenly lost track of his surroundings. He could see himself closing the distance to the ceiling, and with his current rate of growth he'd need to think of something fast if he wanted to keep his workspace in one piece. That's when he got a simple, yet brilliant idea - sit down.

Erm, maybe he was a little too overzealous in his movement. Unaccustomed to his thousands of pounds of heft, he let himself sit down as he normally would, but the astronomic force of gravity acting on him sent him hurting to the floor with a force that he didn't see coming, cratering the concrete like a pair of meteors had just impacted it. That wouldn't be too far off seeing as his overly-muscled cheeks were practically a pair of boulders in their own regard. They'd each swollen far beyond the closest comparison that he could think of - his car - knowing instantly that he'd crush the vehicle into a flat disc of metal, plastic, and glass.

Shit, he was_immense_! The feelings slamming into him were indescribable, especially those emanating from his twin spires. Fuck it - he grabbed onto one of them with each hand, his fingers immediately becoming coated in translucent pre. His balls had grown into the stuff of legends, both easily able to fill a swimming pool on their own had he gotten the chance to test that out. His was currently drained as it wasn't quite summer just yet; if only he'd have thought of it sooner.

His tremendously bloated testosterone factories continued to fatten at an astounding rate, continuing to swell with virile spunk, ready to erupt in a shower of seed when he could finally overcome the hurdle of climax. Oh how he just wanted to cum and get this over with! Yeah, it wouldn't solve his dilemma, but it would at least allow him to think straight again.

Legs thicker than redwoods sat underneath his massive cum tanks, with Miles doing his damndest to stimulate himself enough to get off. Each ripple of pleasure shooting through him got most of his body to tense in reaction, his quads in particular pulsating twice as thick in flexion than at rest. That only provided more surface area for his inner thighs to become inundated with bliss, causing a chain reaction of ecstasy to rattle throughout his body right into his very soul.

While he continued to get taller, he grew thicker at a far faster rate. His pecs, once merely protruding out a foot from his chest, now jutted out about a dozen, with each slab of meat easily around a thousand pounds of beef in and of themselves all bunched up into rock-solid mounds that had swelled scant inches away from his muzzle. The realization of how close they were got him to moan the loudest that he had that whole day, especially when he discovered that an errant flex of his chest got him within kissing range of it. It wouldn't be long before that was a possibility all on its own.

It seemed like no matter what he did, everything that he's produced managed to quickly turn back into energy for more size, save for the pool of pre forming on the floor - to be honest, it genuinely surprised him that he hadn't thought of a way to do that with his invention, but he'd grown thankful that it'd slipped his mind given that he would've busted clean through his work station by then.

Though maybe that wouldn't have been such a bad idea given how hot it'd grown in the room, the temperature sensor doing everything in its power to convert it into more muscle mass for him to enjoy. And his embarrassingly loud moans might not be picked up anymore if he were far enough away from the device. The question then became how far was far enough, and he didn't know if he wanted to actually find out the answer.

The overbearing heat present in the room hot him sweating up a storm, which in turn got his body to produce copious amounts of musk to form in all his muscular crevices. He'd never normally get to experience just how potent his own scent was had his chest not grown close enough to his nose to detect it. Indeed, he picked it up almost instantaneously, desiring more when he did. That got him to flex his pecs with his nose going right into the valley between them, shoved into a forest of chest fur that contained an abundance of the intoxicating aroma. Ah, that could be his ticket!

He huffed like his life depended on it, the ambrosial smell flooding his being with added arousal. Every part of himself now added to the pleasure jackhammering into him, the pressure in his prostate swelling farther than it ever had before. His back had only just touched the wall, though his constant growth left it pressing into it with greater force, making him panic as he stroked his pillars with greater intensity. He had to finish this now before he actually trashed his workspace, and potentially the rest of his house!

Nothing had crumbled as a result of his beef just yet, but that didn't mean that it wouldn't. The structural integrity of the room was great as he requested it strong enough to withstand possible high-explosive experiments, but nowhere in his mind did he expect himself to be the explosive test!

More moaning departed Miles' throat, though the rate of which grew faster as he drew nearer to release. He was so close that he could practically taste it, though that was likely the masculine essence that wafted from his hairy bulk. Still, he stroked himself as hastily as he could, feeling his traps begin to overtake his pointed ears in size, making them the tallest point on his body. It wouldn't be too much longer before they hit the ceiling now.

Which made it all the more imperative that he cum as quickly as he could. It became his sole focus to get himself off, jerking his hands along his throbbing crotch rockets, his fingers thrumming the veiny flesh as preseed continually poured from the tips. His breathing grew laboured the closer that he got to climax, which he hoped was soon as his ass just hit the wall. He'd been bent over as much as he could to keep his walls in tact, but that might not matter soon if he couldn't--

With a mighty roar - that forced another couple hundred pounds of heavy muscle mass onto his engorged frame - he finally got his cum tanks to unleash everything that they'd produced since he'd started burgeoning less than an hour ago, his twin pillars acting like monumental volcanoes spewing his virile foxbatter around his work station. The damage might be a lot to deal with, but that was more than alright in his books.

Entire lifetimes worth of spunk jettisoned from his shafts, geysering out of them like a firehose on steroids. Had there been any paint on the walls, he would've stripped it without trying as the cum nearly applied enough force to crack the concrete. He'd become a colossal powerhouse of a canine, far on the opposite side of the spectrum of what he was used to. At least this was one experience that he wouldn't soon forget.

What felt like whole eternities had gone by, his fattened orbs slowly starting to feel relief as the pressure built up in his taint also began to dissipate. The feeling was immensely satisfying, with him sighing into his titanic chest with glee. To his infinite surprise, he found that he didn't hate this situation as much as he'd have thought that he would, though he chalked it up to the immeasurable amount of pleasure battering him at every second.

The effects of his output were immediate. While he'd had the foresight to safeguard his computer for events similar to this - not exactly like this, of course - the same couldn't be said for his creation, which bore the brunt of his blasts and short circuited as a result. The unlimited flow of energy into his body stopped right away, giving him instant respite as he rode out the rest of his orgasm. His concerns had finally been alleviated and he almost felt ready to celebrate.

Miles was left a gasping mess of unreasonable bulk as the last of his seed streamed from his leviathan schlongs, the drain at the far end of his workspace doing overtime as it tried its best to corral all of the untold litres of jizz into the plumbing below. He huffed with delight that the ordeal had completely finished, but it left him a bit glad that he got to experience this at all. Maybe once he shrank himself down he'd keep some mass for himself as a memento of this occasion, every fondle of it bringing back potent memories. Uh, surely he'd think of something to explain to his family and friends at some point.

Though that would all have to wait as more pressing issues were at hand. Somehow, he was going to have to access his computer again, hopefully able to temper his arousal enough to debug his program and figure out the issue with the targeting function. That was the hard part as, while he'd accidentally destroyed his invention, he wasn't too upset considering that he knew how to rebuild it by memory alone. And he felt it a good idea to do as he honestly had to admit that it had a ton of potential.
