Andy and Rebecca had a problem.

A long-lasting, fulfilling, very sexually active relationship had left them both in a position where they didn’t know what to do next. Not in any meaningful emotional way, but in terms of bedroom matters; after so much time spent together and so many nights “lost” making sure the mattress’ springs were up to task, things were bound to get… monotonous. Not boring per se, but repetitive, which was something that worried them both deeply; if they couldn’t find the same satisfaction as they did before, then what did the future hold for them? Just the same-old same-old, bereft of the spark that made their early liaisons so magical?

To that end, both of them agreed to look into ways to spice up their sex life, and seeing as variety is the best member of life’s spice rack, it was only natural that the two began to experiment. It started off softly enough, simply trying out new positions, but progressed to more in-depth stuff that required a heaping dose of acrobatics and, at times, power tools. Even that could only tide them over for so long, though; months, perhaps, but even the most novel of ideas eventually becomes routine, and from routine takes a highway straight to being boring again. It got so bad that vanilla stuff actually felt like a new experience for a while, but they both knew they couldn’t spend the rest of their lives going through a cycle… or else that would turn boring as well.

Maybe a large wheel with random stuff each week?

While Andy was trying his best to brainstorm up new ideas for their bedroom hours, Rebecca had taken a different approach entirely by tapping into the collective knowledge of all of furkind: the internet. Not the best of places unless one knew where to look, and even then she had to trawl through countless fake links, poorly-made malware traps and even a few well-intentioned but ultimately bogus “supplements” based on spurious-at-best pseudoscience; the last thing she wanted was to take “super milk” pills that forced her to puke out her insides with a massive allergic reaction. However, amidst the enormous, sky-high pillars of bullshit, there was something that kept cropping up: a reference to a phone app that could modify one’s body at will.

Normally, Rebecca would take these comments and shove them onto the same pile as she did the growth bras or hyper juices or whatever else was being advertised to her, but one thing that made her eyebrows rise was how consistent those references were. They were never bots, and yet they all talked about it in much the same way, and with the same name as well: “InBoMo”. No one seemed to know what that meant, or indeed if it was an abbreviation at all, but what truly sparked the vixen’s interest was how every time the app was namedropped, the moderators for whatever forum or imageboard it happened in weren’t too far behind. Something, or someone, was trying to hide the existence of that thing, and that was too much of an irresistible nut to crack for her to just pass up on.

It took her weeks before anything new happened, and even then it was pure luck. When prowling through one of the forums she earmarked as being a potential hotspot, she caught a fresh post containing a link. It was absurdly long and most likely would end up getting flagged by her antivirus software, but the vixen copied it anyway and pasted it onto a text file. Not five minutes later, the post was deleted by a mod, citing concerns over “security leaks”. Now fully engrossed in her discovery process, Rebecca plowed through the inherent mistrust in random links on the internet and opened it.

Surprisingly, nothing of note happened; the website in question was unlisted, but at no point did any notification pop up letting her know she was going into dangerous territory. In fact, the site itself looked to be entirely innocuous; it wouldn’t be out of place as the front page of a major tech company, and in fact it looked to be one, even if neither her nor apparently Google had ever heard of the name “Rivtech” before. It purported to sell a wide variety of products, most of which were electronic in nature, but Rebecca only had eyes for one section: their app store.

There, it only took her a couple of seconds to find what she was looking for. Like a dream come true, there it was, “InBoMo”, the Instant Body Modification app. It was absurd to think it would work, because it literally couldn’t, but the vixen was too caught up in her little victory to care about it in any way. Figuring that the constant link deletion might mean the website migrated to different domains at regular intervals, she downloaded the file and closed her browser and internet connection, then spent the better part of an hour making sure it wasn’t some kind of horrible piece of malware. As soon as her fear was assuaged, Rebecca transferred the software over to her phone and began the installation process.

It was a slow affair, mostly because it got stuck in the “synchronization” screen for what felt like half an hour. What it was synchronizing with was anyone’s guess, but it gave her enough time to go to the kitchen and fix herself some lunch before it was finally done… after which it became patently obvious what the damned thing had been doing all that time. The vixen practically dropped her plate on the ground when she heard a digitized voice say her name, every hair on her body standing on end before she realized it had come from the phone itself. Rushing to see what had happened, she was even more surprised and shocked when the screen lit up and revealed… herself.

It was a 3D rendering of her body, so photorealistic that it could very well have been a direct video feed if it weren’t T-posing and rotating slowly. Everything down to the patterns of colour on her fur, even birthmarks on her skin that she had completely forgotten about, they were all beautifully recreated with a level of detail that left her wondering just what exactly she had gotten herself into. The app didn’t appear to have any menu at all, only the in-built zoom-in function that came with the phone itself. She fiddled around with it for quite a while before noticing a few faint letters on the top right, periodically glowing just visibly enough for her to make out what they spelled: “Voice Command Activation”

“Ok, so, do I need to tell you what I want?” she spoke, thinking she might very well be going completely crazy, “What, do I need to ask you very nicely? Make my tits bigger, please and thank you?”

She half-expected it to work, but of course it didn’t. Her breasts did light up on the displayed model, but nothing else happened… at least until a notification popped up reading “ERROR: QUANTIFY NOT SPECIFIED”.

“You have to be kidding me…” Rebecca sighed, rubbing her temple, “Alright, make my tits bigger by four cup sizes, would you kindly?”

No sooner had she finished talking than the effects began to take hold of her. Yelping in surprise, Rebecca dropped her phone on the floor before her butt became firmly acquainted with it as well, the vixen crawling back as far away from the app as possible, perhaps hoping distance would stop the sudden pressure she felt inside of her bust. If nothing else, the app was certainly thorough: within a short ten or so seconds her bra was feeling incredibly tight and barely fitting, leaving her overflowing from it so much that it was getting hard to breathe! Throwing her shirt above her head didn’t help matters either, as it only revealed the extent of the “damage” done to her; without so much as a warning or a wink, she did in fact grow four cup sizes in the time it took for her to react properly to the change, and judging from how they felt, they were all natural as well.

It took Rebecca a while to process what she was seeing, but the moment the realization hit her was the best moment of her life. Assuming all of that day hadn’t been one long, incredibly vivid dream, then she now had the power to sculpt herself in the palm of her hands, to be used for as long as her phone had any battery left. Her smile was positively psychotic by the time she crawled back to where she’d dropped it, her bra already removed and thrown somewhere else in the room. Though it pained her to ask the app to shrink her down, she had to try; she wanted to use it in the bedroom, not show it off for anyone that might have eyes.

“Alright, send me back to normal please!”

The software took a few moments to react, as if wondering why anyone would want to go back to how they used to be after being shown such potential. Nonetheless, it did as instructed, and Rebecca got to watch as her tits shrunk down to their original weight, leaving her both incredibly unsatisfied and yet somehow even more excited for how malleable her body was. The glint in her eyes was half-unbridled lust, half-maniacal insanity and one hundred percent mad scientist, because Andy would only be coming back home in a few hours and this gave her way too much time to experiment with herself.

The male fox, in the meantime, was trying not to worry too much about his unfortunate situation. He already had plenty to focus on during work, so having to dedicate brainpower to fixing his sexual boredom woes wasn’t high on his priority list; if anything, doing something else helped take his mind off of it, which is precisely why walking back into his home later that day left him so confused. Rebecca’s clothes were strewn all over the place, and while his first instinct was to panic, he then heard her giggle from all the way over at the front door. With a smile spreading on his lips, Andy put down his briefcase and went to work removing his work attire, figuring his precious vixen might have found something interesting for them to do.

“You know, someone’s gonna need to clean this up after we’re done,” he called out, by now completely nude, “and it ain’t gonna be me. And why are they all torn up, did you try to go for the punk aesth-oh my God what the fuck?!”

Andy’s thought process was interrupted by what he saw after rounding the corner in the corridor. The room to their bedroom was wide open, and in front of it was someone with Rebecca’s face. It couldn’t be the vixen, because last he checked she wasn’t so tall that the top of her head was bumping against the ceiling, her ass wasn’t wide enough to have cracked the doorframe and her breasts certainly didn’t cover about half of her torso either. To say nothing of how well-defined those muscles of hers were; it awoke a certain few things in him he didn’t even know were there, and yet all he could do was wonder just who in blazes that woman was supposed to be.

This was not made easy by how when she spoke, it was Rebecca’s voice coming out of her mouth.

“Hey hun~” she cooed, kneeling down and still being taller than him, “I thought I’d give myself a new look and I may have gone a bit overboard… what do you think, though~?”

There were so many things Andy wanted to say that he was wondering if he should say anything at all; surely, the fact that his pants now had a noticeably bulge in them did all the talking for him, no? Rebecca seemed to think so, seeing as one of her fingers immediately poked him somewhere that was incredibly sensitive, leaving the fox reeling from how strong she was.

“Seems to me you’re liking this quite a lot, aren’t you~?” she kept on talking, her voice like honey to his ears, “My oh my, I didn’t know you were into bigger women, Andy~”

“... please explain;” he whimpered back, thoroughly defeated, “I don’t get it.”

The manic grin and fiery look melted away almost instantly after the fox begged for his partner to give him some context, and in that instant the enormous, domineering vixen turned into the overexcited nerd that he fell for all those years ago. She fiddled around with her cleavage, producing a very foggy-screened phone before rambling on about her discoveries, how she found Rivtech’s page, the realization that it was actually all true and the many, many hours she spent experimenting with things before finally settling with the body shape he was seeing in front of them.

“And it’s great too because it doesn’t leave any excedent lying around, I could literally turn back into my normal shape and it wouldn’t do anything to it,” Rebecca rattled off in quick succession, “but it’s not like I’d do it normally really it’s just something interesting to note did you know I managed to make my tits go all the way to th-”

“Rebecca,” Andy interrupted her, “breathe.”

The vixen’s words got caught up in her throat as she flinched, a slight blush spreading over her cheeks after she caught herself going on a monologue again. She excused herself sheepishly before turning her attention to the app and telling it to return her to normal; within a short minute, where once had stood a magnificent, ceiling-tall vixen with curves for days, was now just Rebecca, her body returned to what it had once been, with her twirling around a couple of times to show off how amazing her new plaything was.

“Pretty cool, huh?” she giggled, “You wanna give it a spin?”

“Think it’ll work on me?” the fox wondered, taking the phone regardless, “Do I need to do anything, or…?”

“I’unno, just tell it to synchronize or something.”

Though confused, Andy did exactly that, fumbling with the screen for a few seconds before asking the application to “synch to me”, after which both of them stood around for a good half an hour again, slowly whittling the time as they waited for the software to process all the new information. They could only hope it didn’t take that long every time they wanted to change it from one to another; neither of them could afford to have a wait that long in the middle of their sexual escapades, it’d completely ruin the mood!

Once it was done, Andy’s reaction to seeing himself was far more subdued than his partner’s, though admittedly he was given far more time to prepare for it; on staring at the replica model, all he could think about were all the things he ever wanted to change about himself, all the minute, barely-noticeable blemishes that nevertheless bothered him to no end. It surprised even Rebecca when his first command was to make his right ear half an inch larger in order to match the left one, with the second one being to remove a birthmark on one of his asscheeks that even the vixen wasn’t aware was there. The fox looked terribly embarrassed over his choices, but kept on going through the list, leaving his lover flabbergasted at the sudden vanity; at no point did she even begin to imagine he had so many things he wanted to get rid of before he got to the juicy transformations, but there she had it. Fifteen minutes of admiring himself in front of a mirror later, he was finally ready to get started.

“Alright… time for… or maybe…”

Andy brought his mouth close to the phone’s screen, speaking so low that Rebecca couldn’t hear what he was saying before setting the thing on a table and walking closer to her. He took longer than expected, which was perfectly normal considering what he told the app to do to him: while initially it seemed like it was just an illusion, there was no doubt after a couple of feet that the fox was growing significantly larger between the legs; each step added inches to his cock, each motion made his nuts swing wider and fuller as they bloated with newfound capacity and productivity. Rebecca could hear them from where she stood, her eyes practically glazed over as that thing bulged out to reach her partner’s knees and yet still kept going regardless. It seemed like it wouldn’t stop growing, and indeed it kept packing on mass even after he stopped right next to her, the sounds of groaning as the skin on it stretched itself filling her ears just as much as the package itself was filling her eyes.

When it was done, his shaft, while still entirely flaccid, was poking the floor with its tip, which each ball hung so close to the ground it’d have to contend with the carpet rubbing against it. He didn’t have to say anything for Rebecca to get the picture; the vixen smiled a dreamy smile when she knelt down next to it, marvelling as it was large enough for her to give it a proper hug, rubbing her whole body against it and making the fox so weak-kneed that he had to outstretch a hand to the nearest wall just to keep balance. He wasn’t expecting it to be as sensitive as it was; now that he had Rebecca going at it with far more gusto that he thought possible, he was beginning to regret his decisions. Maybe he should have just made himself larger, that would’ve balanced out the whole issue with half of his neuron endings being somewhere around the groin.

Maybe.

But there was something to it all that made him feel a lot more confident about his position than he had any right to be. Rebecca had hours, hours to practice with the app, and judging from how many clothes were strewn about the vixen most likely experimented with a great many number of forms before settling on her amazonian one. She had plenty of time to get accustomed to it, for her brain to fine-tune itself into being able to comprehend the changes wrought upon it and the body it controlled, while he didn’t. He just came home and saw the end result, then tried to make his cock bigger as a goof and realized he bit off a lot more than he could chew. And yet still he found that this was a lot more pleasurable than it was worrying, and while he should be concerned about that reaction, there were just too many promises hidden away in that piece of software for him to think about imposing limits on himself.

He had already gotten rid of all of his imperfections, made sure to fix even the most miniscule of blemishes that even his other half didn’t know about. But those were just corrections, things to fix in order for him to reach a baseline. Now that all of that was taken care of, now that he had a solid foundation to work on… it was time to improve himself; and what better way to do so than to mimic what Rebecca herself had done, giving himself the kind of body that remained, up until then, within the purview of smutty artwork? The mere idea of it was enough to get his shaft to harden even more, giving the vixen something to think about while his attention focused on the phone again. He turned his head around and made a great number of demands, the first one of which was for the application to synch back to Rebecca; this turned out to be instant, a pleasant surprise once the software loudly announced that it still kept her scan in its database.

What followed was a return to form, with the vixen’s body being made to become the best that it could be, even better than what she had prepared for him when he returned home. She was taller now, so much that she couldn’t even stand without needing to hunch over. Her musculature was so well-defined and toned that Andy was salivating at the prospect of being worked over by her, while her hips, ass and thighs still maintained just the right amount of pudge to remain eminently squishable and far too large to pass through doors. Her tits as well were made to develop beyond what they had already, until she was no longer using her body to service his rod; those mounds made a perfect platform for the best titfuck he’d ever received in his whole life.

One might wonder why Rebecca was forced to change before he did, but that was part of the fun as far as the fox was concerned; she may be big, and she might be so feisty as to fill his ears with all manner of depravities, but she was still enamored by the sight and feel of his cock, and that gave him the upper hand for the time being. All he had to do was lie down and let that beast throb, and his lover would do the rest for him: tease him, knead him, squeeze him, beg for him to grow larger until she too was openly drooling at the prospect, it was all worth it just to set up what would happen next. The house would have to go obviously, but that was hardly important; when he was done playing around with that app they wouldn’t need a house to go back to, nor would any ever be large enough to fit them. It was now their destiny to embody excess, and Andy was rather excited to go down that road.

His plan went off without a hitch, and he got to spend a good ten minutes having an amazonian mini-giantess tending to his every need without so much as stopping to breathe. It was getting so hot in the room that he felt sweat pouring down from his brow, and if not for a timely request for his stamina to be improved, it was quite likely that he would’ve blown his load long before he had the idea to join his lover and grow out his own body. Of course, it wouldn’t do to simply become taller or bulkier; it wouldn’t even do for him to become perfect. No, the fox’s body had to be sculpted in such a way that everyone, literally everyone who saw it would drop to their knees in adoration, unable to resist its allure; the only person who would ever be immune to it would be Rebecca, because honestly things were a lot more fun when they were both operating on the same wavelength.

Not even bothering to grab the phone, Andy instead barked out a series of orders meant to transform him into the pinnacle of perfection and beyond, with the house rumbling all around him as the process began. Every unnecessary ounce of fat was burned away from him, replaced with sinew and rock-hard muscle mass, glistening under the ceiling lights and the sheen of his velvety-smooth fur. His pecs and abs grew so well-defined that they could probably be used to grate cheese without much hassle, while his biceps bulged out to the point where it felt and looked like Andy was constantly flexing. His body bulged out in every direction until the hallway they were in lacked any room to move in, his paws in the living room and his head in the bedroom, more or less completely stuck while the smaller vixen continued to work on his shaft. She’d soon have a lot more to work with as well, given that it grew to match the fox’s torso in length and about half of it in girth. His nuts, too, grew to encompass most of his thighs and part of his knees, becoming large enough to overflow from them and so tight that any amount of pressure placed on them was enough to get him to spurt gallons of his seed; there was no precum left to give to anyone, just the real deal.

Rebecca did a wonderful job at keeping up with the changes, but seeing as Andy was now reaching fifteen height in height and his shaft was about half of that by itself, there was only so much she could do with her own nine feet; the vixen tried to pleasure it as much as she could, but it was clear that her current body just wouldn’t cut it. Of course, this didn’t mean she’d stop; Andy’s head being next to the phone gave her the perfect excuse not to enact any changes upon her, instead offloading that job onto her partner with a wink and a moan… but mostly a moan. The changes were simple, and the fox quickly queued up a series of them that amounted to making Rebecca about as large and well-proportioned as he was; what really sold it wasn’t the growth spurt, but how it finally tore down the walls around them.

There wasn’t a lot more room where they could exist in, so the building became a thing of the past. Clouds of debris floated around them when the two became equals in scale, muffled yelling coming from all around them as their neighbors loudly wondered just what was going on. Meanwhile, the two vulpines were deeply engrossed in one another, especially now that Rebecca had enough bosom to her to give her lover’s cock a proper tittyfuck, even if she had to poke her head into the floor above to do it; not like Andy hadn’t done so already, after all. The two forgot where they were, the fox in particular lounging about with his hands behind his head while he watched his other half try and fail to bring him to climax; the vixen’s inner thighs were wet with her own juices, her face stricken with need and her body shaking as the thought of being speared through by that colossus of a cock kept nudging its way into the forefront of her mind… and yet, Andy refused to orgasm, his seemingly-infinite stamina only increased further by the extra size and mass he was given.

A perfect opportunity to turn the tables.

The house was surprisingly easy to take down once he began moving, the walls offering about as much resistance as wet tissue paper when he lifted himself to a seating position and grabbed Rebecca’s shoulders, the vixen’s surprised expression turning to shock when she yelped at being pulled down and turned around, her back to the fox’s front and her partner’s shaft emerging from between her own legs. Now that she got to admire it in its full glory, throbbing, its veins pulsating, thick ropes of Andy’s seed bubbling from the tip with each heartbeat, it was even more delicious than she first thought; Rebecca couldn’t wait to feel that thing split her insides in half, and the burgeoning fox giant beneath her had no intention to keep her waiting. He arched his back and aimed his cock directly at her slit, not even bothering with any more foreplay before bucking his hips and thrusting forward, plunging most of it into Rebecca and bulging out her insides.

Biology had already been thrown out the window, so seeing his own shaft outlined against his lover’s skin didn’t strike Andy as particularly out of the ordinary; if anything, it was just further confirmation that the two of them were destined for greater things than just conventional sex or roleplay. The world was their oyster, and now that they knew that for a fact, it was about time for said world to get a good glimpse at them. He turned his head to the side, confirming the phone was still there, and commanded the app to synch to both of them, a risky move that nonetheless paid off after a couple of seconds of processing. His dick was still firmly hilted inside of Rebecca, whose eyes had glazed over and whose tongue was lolling out of her mouth while her brain tried to comprehend what was happening to her, and with that came an idea: making their sexual encounter also be the vehicle for their growth.

Andy ordered the software to make them larger while maintaining their proportions, but to only do so whenever he thrust fully into the vixen on top of him. The moment Rebecca heard this, rather than moaning out even louder than before, the vixen instead added that their climaxes be linked to one another; this surprised even Andy, who had assumed that her greatest desire would be to cum her brains out as quickly as possible. Rather than that, she turned her head around, planted a deep, unashamedly tongue-filled kiss on him, then demanded he fill her up in the most obscene way possible, using words and expressions that even the fox found to be provocative enough to make him blush furiously.

Still, the intent was clear and so was their lust, so why even bother trying to hold back? Though it took a bit of acrobatics and back-bending exercise to get it to work, the conditional growth kicked in the moment Andy anchored his feet properly and restarted his thrusting into Rebecca, himself grunting just as loudly as she squeaked and begged for him to keep going; it was only then that Andy realized that maybe not setting any kind of limit was, perhaps, a very bad idea, because the first growth spurt alone was enough to completely destroy their house and significantly damage their neighbors’, and by the time they realized that had happened the two of them were already on the outside… or rather, there ceased to be a building for them to be inside of.

By all means, they should’ve stopped whatever they were doing and taken stock of their situation; it was miracle that no one got hurt when the whole building came crashing down on them, though plenty of people were grumbling loudly about the whole situation, and their bodies were already threatening to flatten a significant portion of their city block. In any other situation, their sanity would’ve prevailed and the two vulpines would have stopped… but not then. Not ever, in fact, not after being shown what it was like to wield the powers of creation for their own lewd benefit; why stop now that they knew things could be made to last for as long as they wanted them to? They could destroy everything around them just by fucking one another like rabid bunnies, and if there was anything they loved doing it was precisely that.

Rebecca in particular took to the exercise a lot better than Andy expected her to; it was so easy for her to just lie back and get rutted into the ground, especially after she already gave up the “feisty tough amazon” act and made it explicitly clear how much she wanted his cock inside of her. But maybe the ascension into a giantess had given her the same kind of enthusiasm as it did him, because she didn’t look like she wanted to play the part of the pliable fucktoy… at least not as much as before. Both her hands were firmly stuck to her breasts, squeezing them hard enough where Andy was wondering if it shouldn’t be painful to her, while the claws on her feet were digging long, deep grooves into the road, sidewalk and ruins all around them. Their position was untenable with what she had in mind, and they both knew it; for that reason alone, the fox helped push her up, just so Rebecca could have some fun being a cowgirl for once.

The vixen was beyond herself at the new sights, enough that for a few brief moments she even forgot what she was riding on. The whole city sprawled out in front of her, a carpet of roofs that only the tallest of highrises escaped from. She gave it a single, long look, and in that moment knew that it wasn’t enough. She was still building-sized and that was terrible; it just wasn’t right for either of them to be so small, and to that end, she knew exactly what to do.

Impaling herself on Andy’s cock was fun, but there came a point where enjoyment had to come in a more refined way; for her, this meant slowing things down to a point where she could enjoy the sight of a manhood that colossal stretching her insides out so hard that she could feel them being rearranged just trying to take that beast into her. It also conveniently gave her the time to start doting on those nuts of his, both of which were easily large enough that they could fit a large bus inside and still have plenty of room. The fox wasn’t about to say no to this; it was always a pleasure when the vixen showed some initiative and took matters into her own hands, as it let him kick back and relax while being given one hell of a show.

That day, however… wasn’t so simple. Maybe it worked when they were person-sized, but now that each motion carried with it the threat of tearing out large chunks of the buildings around them, everything was magnified a thousandfold. The sight of his cock vanishing into his lover’s lower folds, only to reappear as a stretched-out bulge the size of her lower torso was enough to get him to involuntarily thrust upwards and ignore any kind of pacing; this obviously led to the both of them growing even more, thus making the problem significantly worse. All the while, Rebecca did her best to keep a rhythm, employing the best theatrics when she heaved her body off the shaft it was stuck on and then fought gravity all the way down. No doubt, if they weren’t destroying everything around them, it might’ve been some great entertainment for everyone on the streets; as it stood, they were tearing through tarmac and concrete every few seconds, the panicked crowd just barely staying ahead of them.

It was heaven… and they couldn’t get enough of it. Andy in particular was struggling to keep himself together, but for once he wasn’t fighting against his need for release, but against his brain telling him to grow bigger. He knew, deep down, that what they were doing was unsustainable and would eventually come back to bite them in the ass. He knew they had to stop, that he alone had the power to say that enough was enough and get Rebecca to go along with him… but he didn’t want to. Or at least, a large part of him didn’t want to; there yet remained a small portion of his mind that clung to delusions of control, to the belief that what they were doing could be halted at any point or, heavens forbid, turned back around. That bit of himself was under siege by literally everything else, and the moment Andy’s head plowed through one of their favourite shopping centers, its death was all but assured. There would be no control, no limits, no nothing; the two of them were going to keep growing until there was nothing left that could stand in their path, and if he had to fuck the vixen raw against the ground until they were both sweating enough to fill several lakes, then that’s exactly what he would do. No more beating around the bush; things were going to escalate and he was going to make sure they didn’t stop until the city was flattened, damn the consequences!

He ordered the app to “increase the effects”, not really thinking about what that would mean in practice; in fact, he was barely even aware if the phone was even still there at all or had already been turned to dust by all the constant grinding they were subjecting their surroundings to. He received his confirmation the next time he bottomed out inside of Rebecca, and not only did half of the city get vaporized in an instant, but every neuron in their body screamed in unison at the sudden beating they received; the fox didn’t think that not specifying which effects might have a few unwanted consequences, and now both of them were stuck with bodies that reacted to the slightest touch by making them cling off the edge by a single thread… and there was a lot of body to go around between them.

Even the breeze was starting to be enough, which was quite a bit of a problem for the vixen, whose body would soon be approaching the lower cloud layers; she was already tall enough to be constantly buffeted by gusts of wind stronger than those at ground level, and if it weren’t for her hands being stuck to her tits, then she might just have complete broken under the strain. As it stood however, the increased sensitivity and the sheer size of them ensured that there was very little Rebecca left to break at all, replaced with a mindless beast driven entirely by ravenous sexual desire and the need to get fucked even harder, all of that being fuel for the true pleasure of ascending further and further towards godhood… or something. It was hard to think when she was in a perpetual state of near-climax.

Thankfully for the both of them, thinking wasn’t really required of them, merely mindless thrusting, groaning, moaning and the will to keep on going far past the point where they should’ve stopped. Curiously, things didn’t seem to get worse as time went on; surely at some point it should’ve become harder to move with their frames being as massive as they were, square cube law and all that, but thanks to Andy completely mismanaging his requests and leaving them so vague, the application had added “muscle mass” to the list of things that grew along with every full motion of the fox’s cock. If it wasn’t enough that every hilting made them tear a larger and larger gash into the surface of the planet, now their well-defined musculature was being made even more absurdly toned with each full cycle as well. If Rebecca was an amazon then Andy had to be a true Adonis, his sculpted physique the true definition of unblemished and perfect, practically glinting in the sunlight from the downpour of sweat coming off of it. And in the middle of all this they still hadn’t reached climax!

… and they wouldn’t, given the fox’s commands. Their increased stamina was a product of the software’s fiddling with their genetics, hence it too was included in the proverbial list of things to improve. For each thrust, each bucking of the hips, each half a mile of land wrecked, they were still no closer to orgasm than they were before. There were ample fluids to go around, that much was for certain; even with Rebecca’s insides being as stretched as they were and her slit still being wonderfully tight despite the constant beating it was receiving from a shaft of that size, there were still whole lakes of cum pouring out of her, Andy’s productivity being such that, were he not constantly releasing, then his backed-up juices would force him to bloat out so hard as to completely overtake the growth itself. Rebecca herself had joined the fun as well in that regard; though nearly not as leaky as her lover was, both her breasts began to exude a river of cream each, their swollen teats producing two waterfalls of such dimensions that whoever was lucky enough not to be caught up in the deluge of cum would surely be swept up in the second wave.

Their fluids mixing made the atmosphere around become suffused with such a confusing, yet overwhelming scent that both vulpines were sent into overdrive, driven to fuck like animals when all concern for their well-being left their minds. Andy reached forward to grab Rebecca by the shoulders once more, this time flipping both of them over and pinning her against the ground with her front to his. Just as he lowered his muzzle to glue it to one of her tits, drinking deeply and greedily from the font, so too did the fox continue the motions that had brought them there to begin with, moving his lower body with renewed vigor, his eyes occasionally darting downwards to see the colossal bulge he was giving her with each motion. The world around them would certainly like to see as well, but it was too busy being destroyed by the couple’s ascension, their forms utterly obliterating anything that stood in their path. With each moan, each grunt, came an earthquake and a shifting of the atmosphere, their bodies assaulted from every direction by cold, harsh winds that nonetheless never failed to yield the same kind of pleasurable yelps from them as a tender caress would.

They were operating on scales they couldn’t even begin to understand and that was fine; the point was no longer to think or consider their options, but to feel, to do, to fuck, forever and always. For Andy, his whole world was now his vixen, his love, there underneath him begging him to go faster, to thrust harder, to fuck her raw; both of them were starting to feel the effects of the fox’s poor choice of words, their bodies ready to keep going for hours but their minds begging, aching for release. Hormones flooded their systems in such vast quantities as to be able to fill up smaller cities, and before long even Andy couldn’t keep going anymore; it wasn’t that he was tired, but the lack of a climax left him such a frazzled mess that he had to stop for a few seconds, hands on either side of his mate’s torso, mouth wide open and creating small tornadoes with each exhale. Rebecca too was trying to make sense of things, her body not at all ready for the kind of trials it was being put through.

They locked eyes for a moment, and though it pained them, they knew they had to take a step down from where they were… but only just a step. Rebecca was the one to take initiative and call out for the phone, not knowing if it would work, but she failed to account for the fact that she was mentally exhausted, too far gone to make good decisions and, perhaps most importantly, didn’t really know how to operate the software on more than a base level. All of these should’ve let her know that her words would have to be chosen very carefully, but being the kind of person she was, plus the whole being larger than a metropolitan area thing they had going, both conspired to ensure that what she said next made things so much worse than they already were: “make us cum more easily.”

They understood the mistake they had made mere seconds after it was done, and by then it was too late to do anything about it. The stamina issue wasn’t resolved, and neither them growing larger and more… everything, whenever Andy forced himself fully into her. What was fixed was them not cumming their brains out, and goodness was it fixed far better than they could’ve hoped for! Both of their floodgates opened on a level never before seen; if the mess they were making was already immense, then what followed after Rebecca’s haphazard command made it look like a defective garden hose on a colossal scale. The landscape around them was painted white by the sudden outpour of seed from Andy’s manhood, bulging out the vixen’s belly so much that even his cock’s shape, outlined against her skin, vanished amidst an overinflated belly stuffed with his spunk. Rebecca’s eyes rolled upwards into her skull just before her voice broke completely, reduced to a pitiable squeak as her body’s limits were stretched very close to the breaking point.

As for Andy, he didn’t know what to do. He had a titanic-sized fire hydrant with a leak attached to him now, and even if he held still, the mere act of being inside of his partner was enough to get him to release with full strength. He could literally do nothing else and he’d still be constantly pouring out a small sea’s worth of his seed… and that was oddly arousing. Far more than it should be, even more than anything else they experienced. Just the thought that he was now stuck in a constant state of orgasm, oddly enough, gave him more energy to work with, even when his legs began to shake underneath the onslaught of sensations taking him over. Knowing that he could make it even worse by powering through the curtain of hazy lust and forcing himself deeper into Rebecca made it an even more delicious prospect; he was already so productive that he could barely imagine what a boost would look like.

But he wanted to find out.

Despite his body’s best efforts to knock him unconscious from growth overload, Andy anchored his trembling feet on the ground and moved forward, plowing through the flood of cum pouring out of him to plug Rebecca up completely. The results were astonishing: he could feel her belly swelling even harder still, pushing up against his and almost knocking him off of her from the impact! The moment he bottomed out, things magnified just as expected: not only did they undergo another colossal growth spurt, tearing through a large chunk of the hills west of the city and completely ruining a few outlying suburbs, not only did their sensitivity increase tenfold and leave them shivering just from existing, not only did their stamina get boosted once again… but their climax came even more easily than it did before.

Literally all Andy had to do was stay put and everything would solve itself; a small motion of his hips and there was just enough room between his base and Rebecca’s slit that she could vent the excess cum he was giving her, helping them to lie atop a growing landscape of creamy white that just seemed to be growing out of their control, much like everything else around them. His muscles clenched of their own accord, his body twitching and groaning, trying its best to keep up with what was being demanded of it. Both of them were stuck somewhere they couldn’t get any rest in; the moment a climax abated, another one came knocking immediately afterwards, be it from themselves, the wind, generally just existing as entities or a million other different things. Much as they wanted a second for themselves they were instead forced to go through orgasm after orgasm, their bodies’ immense stamina being tested by how much the experience was draining them. Soon enough even Andy would have to collapse, falling onto his partner’s chest and triggering yet another round of climaxes that left them unable to even think properly.

Something had to be done, but whenever they tried to call for the app to stop, their voices would be interrupted by involuntary moaning and the occasional roar, their brains slaves to the rush of endorphins being produced every half-second or so. There was very little they could do but keep trying until they powered through it, and even then, with their immense power and divine status, it still took them about ten minutes before Rebecca got a command to synchronize to the both of them out, and twenty more before Andy produced a full sentence: “Make us cum normally!”

Respite. Against all odds, things had finally stopped… or at least halted for long enough that the two of them could enjoy a few moments where their bodies weren’t out of their control. Perspective was completely out of whack, with their sight dominated by them and the planet’s curvature; anything smaller than that or the local geography looked like little more than flat adornments on a map, leaving them unable to ascertain just how large they were, or where any part of their bodies happened to be. It was only after being given that moment to rest that Andy and Rebecca fully realized just how colossal they had grown: their bodies were still buffeted by high-speed, high-altitude winds, but they had become so large that they barely even registered anymore, whereas before they had kept them constantly on edge. They felt deathly cold thanks to their proximity to the upper atmosphere, and yet their presence warmed one another. Their eyes could see so far that the planet looked to be absurdly tiny, and even then they could still go for so much longer… it was a confusing mess to try and make sense of, hence why the fox chose not to do anything else but lie on top of his other half until he recovered his breath.

The vixen was in no rush to continue either; the constant climaxing might have stopped, but the effects it had on her certainly didn’t. She was light-headed to the extreme, not helped by the amount of oxygen she needed and wasn’t being adequately supplied, at least until she remembered to ask the app to let them survive without needing to breathe anymore; it was an absurd request, and yet she made it anyway, utterly unaware of the tone shift that implied. Andy followed suit, remembering that they would need some protection against the vacuum and asking for that as well, followed by Rebecca requesting the ability to move around without needing any kind of thrusters. What followed was ten minutes of them shouting at a phone that, miraculously, was still working as intended, and it struggling to give them what they wanted despite how many laws of physics had to be broken; by the end, however, the two were ready to take the next step… or next leap, as it were.

There was no other way that trip of theirs would end if not with their bodies outgrowing some national boundaries. They both knew it, even if they had spent every moment up until then denying it. The couple was already about half as large as their own country anyway, so it wasn’t that much of a stretch for them to take up all the room that was left; hell, all it’d take would be to thrust a few more times and for Andy to hilt him properly and they’d probably overflow entirely! Not that either of them wanted to go through with it right away; what was the point of being that large if they couldn’t enjoy one another’s company before the final explosion?

Barely any thought was given to the amount of damage they were doing to the planet itself when they rolled around, Andy placing Rebecca on top of him before flipping her over, preparing the both of them for the final sprint before an ultimate climax. He at least remembered to make that possible at all, calling on the app to return their stamina to normal (if proportional) levels so they even could orgasm properly; this resulted in them feeling a noticeable shift right afterwards, as if their previous experiences in macro-scale fucking caught up with them and demanded their bodies feel what they had done to themselves, leaving the two panting even harder than they already were, their muscles aching and their limbs sore from all the weight they had been carrying.

There was still some strength left in them, however, enough that the fox brought both arms to bear and wrapped them around Rebecca’s torso, just beneath her luscious breasts; the vixen took the opportunity to caress them once again, greedily kneading and massaging her tits while turning her head around to plant a long, deep kiss on her lover’s lips. The fox giant’s grip tightened, the claws in his paws sunk deep into the planet’s crust, and his muscles tensed in preparation for what was to come. The vixen, for her part, could do very little but brace herself for what was about to happen, and even then it still made the initial impact only slightly more bearable.

Andy, it seemed, had remembered a crucial detail about their growth: it only activated if he bottomed out. At no point did he say anything about thrusting in general, leaving him free to buck his hips wildly and still remain the same size as before; with her back to his front and their bodies about ready to burst, there was nothing left but to rut her like a wild animal and hope for the best, only exercising the bare minimum control required not to hilt his cock completely into the fennec. That his knot had popped out certainly helped; with their stamina restored to what were nominally “normal” levels, his body reacted to the sudden rush by having that thing engorge to the point where even Andy, in his lustful, half-conscious state, knew that the moment he plunged that thing into Rebecca, he wouldn’t be able to take it out even if he wanted to. He had to make it count, had to make sure the both of them were moving on the same rhythm and dancing to the same tune, that their release and final climax could arrive at the same time.

This was far easier than he could’ve expected it to be, in part thanks to them already being beyond exhausted and running on the app’s equivalent of fumes; all it took was a couple more minutes of frenzied thrusting before they both felt the end to their little exploratory session approaching at fast speeds. Still, Andy refused to give in, knowing that the only way forward was to keep going with as much strength as he could muster for as long as he could. His growling turned to stifled grunting, coming in spurts through gritted teeth, his breathing laboured as massive currents of air were shifted and changed from region to region in order to keep him going. Rebecca’s voice was once again reduced to half-maddened squeaking, on occasion begging for her partner to go faster, or harder, or deeper, wanting to feel the rush of growth one more time, already in withdrawal from their ascension having been halted.

The planet itself was taking a beating from the two vulpines’ frantic lovemaking; not only were Andy’s claws digging grooves in the ground that would rival the deepest of ocean trenches, but the earth itself was being cracked and torn asunder whenever any of their bodies impacted it, creating earthquakes that were rivalled in strength only by the sonic blasts produced by the fox’s occasional roar. Theirs was a symphony of destruction as much as love, and though they were aware of this, to some degree, though they couldn’t bring themselves to care; all that mattered was one another, there in that one moment of perfect, orgasmic bliss they were trying to achieve. Both lovers felt it coming, far more quickly than they could’ve anticipated, leaving them just barely prepared for when Andy did what would’ve been the unthinkable, and with a final, powerful thrust, sank himself completely into Rebecca’s slit.

The resulting scream of agonized pleasure was heard across the world, with the vixen’s eyes rolling upwards into her skull right before she sensed the first blast of hot cum hitting her so hard that it felt as if her insides were going to burst. It was even better and more powerful than when they accidentally turned their orgasms up to eleven by accident; maybe because it was all-natural, or most likely due to their bodies being so completely spent that it was their way of letting the two foxes know that it was about time to stop and give themselves some rest. Whatever the case, Rebecca’s muscles ceased to function properly at about the same time she saw her belly start to bulge out, just as the two of them underwent the final growth spurt.

To call it colossal would be an understatement, as the coupled burgeoned outwards to meet boundaries they knew for a fact should’ve been impossible. Andy in particular left a massive trail of devastation thanks to forgetting to retract his claws, deep gashes in the planet’s surface being produced as his paws approached one end of the country while his head raced towards the other. In just a few seconds he could feel the cool waters of the Pacific lapping at his toes while the hair on his head was being soaked in the Atlantic, his body in between feeling everything from hot currents of air to the coldness of the upper atmosphere and everything in between, a bizarre collection of sensations that left him unable to process any of them. It was already bad enough that he was still pumping into Rebecca, he didn’t need his nuts being dunked in cold water and forced to clench tighter.

But the vixen certainly appreciated that, at least in the precious few moments of lucidity she still had left. Her hands had left her bosom to focus on her belly, letting her fingers stretch out as much as her skin was, like a breath being taken that never stopped pouring air into her. It was extremely filling, far more than it had any right to be, and thanks to the popped knot inside of her, every last drop was being held back from leaving. Her insides were not only stretched to high heavens by the shaft piercing them, but now had to contend with a flood of cum so voluminous that it could very well have flooded the country entirely if not for her taking one for the team; an act of utmost generosity she was more than happy to perform.

Moments passed in silence, neither of them able to say or do anything beyond remaining as they were, waiting for the release to end. They could hear Andy’s nuts clenching on delay, the sound barrier being broken but still needing quite a bit of time before the shockwaves hit their ears; they were still powerful enough to rattle their ribcages, and enough that the fox himself was having trouble keeping his back arched. When the final spurts came and he felt his climax finally come to an end, all control left him and he collapsed, kicking up dust storms heading north and south while cracking the planet hard enough to nearly break through to the mantle. It was a miracle that their bodies had somehow avoided hurting anyone; they now bore millions of passengers who had somehow gotten stuck to their fur in various places, not that they were aware of them. Even if they were, it was doubtful they’d care much; they just ruined a significant portion of the planet’s surface and the only thing on their mind was how soon they could go at it again.

Not for the next several hours, though. The strain placed on their bodies was such that their refractory periods inflated almost as badly as Rebecca’s belly had, leaving them both thoroughly spent, exhausted and unable to move. The vixen was already busying herself cooing over her cumgut, trying to push her fingers into it only for it to refuse to budge, while Andy was desperately trying to find a way to lie down that wouldn’t mean being smothered by the weight of his own climax bulging Rebecca out against his torso. Only one thing was for certain though: this wasn’t over, not even by a longshot.

After all, the phone was still there. They could even hear it synch up to the both of them again...
