Everything was going perfectly fine until she decided to go out and train under the sun.

The whole day had been about as monotonous as it could be, with nothing out of the ordinary happening, being suggested, or apparently being possible. Both Heather and Stella got out of the bed, had breakfast, spent their morning cleaning the house thoroughly, enjoyed some lunch and had decided to spend the afternoon just doing whatever in order to pass the time; Stella had the plants in her garden to water, and Heather had her training regimen which she religiously followed every day. It was important to stay in shape with a body like hers, lest her prodigious bust end up causing no end of back pain, and besides, it was something to do in order to help stave off boredom and get that sweet, sweet serotonin hit she so desperately craved at times. So, the Poké-gal got her sports bra and shorts on, grabbed a sports drink from the fridge, and headed out into the backyard in order to enjoy herself.

And, at least for a time, it seemed like things would carry on the way they usually did. In fact, nothing out of the ordinary seemed to happen at all, apart from the can she brought from the fridge being remarkably different than the usual brand; Heather recalled her partner saying something about a “new thing” that she saw on the news and wanted to try out, something about a sports drink that was also a diet soda while simultaneously being something to be enjoyed as a fine drink, a combination that was, as far as the Lopdra cared, positively ludicrous. At least it tasted somewhat nice; nothing out of the ordinary, but not like some of the swill she’d had the misfortune of experimenting with in the past. Certainly nothing that would indicate what it had in store for her.

So, she resumed her workout, going through the motions the way she usually did. Heather had initially started getting exercise done after a growth spurt left her with a set of breasts a bit too heavy for her body to carry properly, especially given how light she already was, but by the time her back was well-toned enough to carry those things without too much trouble, she’d grown so accustomed to the routine that it almost felt like a waste to just stop; besides, it had given her a physique that, truth be told, was enjoyed by herself and Stella in equal measure, and if it let her last longer in the bedroom while providing for her partner even more, then why stop? At least, that’s what the logic had been up until that point, and given that nothing strange had happened, Heather saw no reason to think that anything would be different. That is, of course, until about thirty minutes into her cardio, when she felt something inside of her chest.

Having never experienced any side-effects from skirting so close to lunch when starting her workout, to suddenly have that odd sense of churning pressure push against her from the inside left Heather slightly concerned that something might be dreadfully wrong. Then again, despite the sensation coming mostly from where her lungs were, she didn’t feel short of breath, nor did she start to hyperventilate, voluntarily or otherwise; in fact, apart from the pressure just being there, she felt exactly the same as before, and since it wasn’t exactly painful or anything of the sort, it left her feeling more… mildly uncomfortable rather than anything else, like a foreign body had just lodged inside of her without actually affecting her in any way. The goo-bun was about to turn around and call for Stella’s help when she noticed that there was something remarkably different about herself when she tried to move: her balance.

Having had time to get used to her new bust, the change in Heather’s center of gravity had long-since migrated to that part of her brain that no longer worried about things and just sort of went on with its day, relegated to automatic processing, if even that. Thus, when she tried to move around and was met by the same kind of sudden weight shifting that she’d had to deal with it those many months prior, Heather was slightly concerned about what might be happening to her; the cause for this was obvious, and indeed should have been perfectly evident if she only bothered to look down, but doing so would give her confirmation, and the Poké-gal doubted whether she’d be able to keep her wits about herself if she had undeniable evidence that her tits were getting bigger again. Not that it was a bad thing, but she was part Lopunny, and what they said about rabbits had an unfortunate tendency to be entirely spot-on; getting that kind of workout so soon after lunch might genuinely have nasty side-effects.

She couldn’t help herself though, not after taking a step and feeling her breasts bouncing in a way that shouldn’t be possible with her sports bra being as tight around her chest as it was; there shouldn’t be any bounce, much less the kind that brought to mind memories of that time she spent dealing with the extra cup sizes before buying entirely new lingerie. Again, not exactly the worst of memories, but being horny during a potential growth spurt was not the best mindspace to be in if she wanted to avoid any unnecessary injury to herself; it was depressingly easy to get caught in the process and forget about such things as walls or sharp corners. Or bras snapping. Or clothes ripping. Or a myriad of different things that Heather was certain she was going to experience before the hour was over.

She wanted to say something, but each time the bun opened her mouth to speak, whatever words she could conjure up were left stuck in her throat and unable to move any further from that, just as her hands refused to stay put and began to gravitate towards her chest at about the same time as her feet stopped moving her closer to the house and instead remained rooted in their spot. Heather would soon be feeling the softness of her bust, sinking her fingers into it as she felt it expand in every direction, pushing against and overflowing from her tight clothing, the ripping and tearing of fabric accompanying each inch that she felt herself gain; the bun couldn’t even look down to see it happen in real-time, knowing for a fact that if she were to stare at her own cleavage, deepening and lengthening as the tits creating it grew fatter and fatter still, she’d drop to her knees and immediately give in to her own arousal.

Then again, she ended up doing that anyway, making the whole thing a moot point; there was only so much one could withstand when it came to that sort of stimulation, and as soon as her sports bra outright snapped, forcing Heather to hold the tattered remnants of it with both hands, the sudden weight on her palms was enough to make something click inside of her head. Now there was nothing in there but those exact sensations, the softness, the warmth, the sheer size as it oozed between her fingers… she wanted to let go, allow her bra to just fall onto the ground and have her breasts set free, but not yet; more was needed, to make the final release that much sweeter and more enjoyable.

Just as Heather was starting to deal with a pair of breasts that were very quickly becoming big enough to cover most of her upper body, Stella was starting to feel like something was… definitely off about herself. She’d never been quite as blessed as her mate was, and even if she was, she probably wouldn’t have taken up exercise as a regular thing; rather, the Poké-gal was one far more inclined for the simple, mentally fulfilling exercise of gardening, and was happy to spend hours tending to her beautifully, meticulously cared for flowerbed. It had taken months, sometimes years of hard work to get it to the state that it was, and though most of the work required was just maintenance, there was still enough space left to do some experimenting with exotic seeds; none of this left her even remotely winded, much less tired or exhausted, which is exactly why the sudden shortness of breath caught her so off-guard.

Though, it wasn’t necessarily hard to breathe as much as it simply felt like it should be. It was hard to describe, almost like she’d just swallowed something and it got stuck in her throat, despite Stella’s lunch being very much safely packed inside of her stomach. It was bad enough to prompt her to take the can of drink she brought from the fridge and take a couple of sips to hopefully get rid of whatever that blockage was… only for the sense of intrusion and pressure to grow worse instead. The Goodra hybrid practically keeled over as she wrapped both arms around her belly, just barely managing to miss her garden when bending over, her teeth gritted as she tried to stifle a loud, painful scream… yet there was no pain there, none that she could tell at least. There should be pain, from what she was feeling, but instead it was almost relaxing, in an odd, roundabout way; it wasn’t until she opened her eyes and looked down, seeing what was happening to her breasts, that she realized what was happening.

Sprinting through the house to warn Heather not to take the spiked drink was made remarkably harder than it should be thanks to those new weights on her chest, harder still considering they never really stopped growing. Each leap she took caused her breasts to bounce eagerly on her torso, ripping through her clothes almost pathetically easily as they packed on pound after pound of mass from seemingly nowhere; the process took her by surprise, and progressed so much quicker than it did with Heather, thanks to Stella drinking more of the tainted substance, that she actually had to stop running after barely covering half of their house. Not because she was too tired to do it, but the sensations had simply overpowered her better judgement, leaving her unable to do anything but shamble towards the closest door, tongue lolling out of her mouth, dragging her feet across the floor as her hands flew to her bloating, swelling breasts to find them so immensely engorged that her fingers could sink and vanish into their plush pudge.

Better yet, it wasn’t just her bust growing larger; though it was nearly imperceptible at first, Stella eventually came to realize that her slow motions were being seriously unbalanced by quite a bit of extra weight somewhere below the waist, and after successfully wrenching one of her hands away from her tits and onto her ass, her suspicions were confirmed when it indeed grabbed hold of a cheek that was substantially larger than what it was just moments before. The ensuing moan was loud enough to be heard all the way from across the street, and certainly loud enough that Heather, also stuck in place and fondling themselves, was given the confirmation they needed to know that their partner was undergoing the same transformation they were.

Even still, it took them the better part of ten minutes just to cross the few remaining yards that yet separated them, what with their feet refusing to obey them when they tried to get them to move in any direction at all, and their minds being so focused on extracting as much pleasure out of their burgeoning bodies as possible that they occasionally found themselves forgetting to breathe properly. It was an overwhelming experience, especially when their bodies themselves began to expand outwards along with their assets, ensuring that getting through the last couple of doorframes was so much harder than it should be, and yet so much better than it ever could be. With Heather on one side pulling on two arms and Stella on the other trying to push herself through a tight opening, her ass stuck between both sides of the door, the two would inevitably end up collapsed into a heap of goopy curves once the latter popped free from his constraints, tumbling around along the ground for a couple of feet before stopping in an odd, but oddly comfortable position.

There was no way either of them were going to resist the allure of the other one’s body at that point. Even the short time they were apart was enough to cause immense changes to their physical forms, with body women significantly taller than they used to be, and their curves magnified, if not tenfold, then very close to it. All they could do was feel as their tits smushed against one another and their legs rubbed up in ways that defied conventional logic with how smooth and delectable it felt, all while they bloated further, filling with phantom mass as the tainted drink worked through their system and continuously improved them. With a gentle push, Stella was moved onto her side, the weight having become too much for even Heather to deal with; this allowed the two women to truly get down to work and focus their attention on one another’s burgeoning frames, their hands flying from curve to curve as they found new and more inventive ways of taking advantage of their heightened sensitivity. Even a single squeeze was enough to elicit a throaty moan, with anything more leading to their bodies vibrating as their constituent goo lost some of its solidity with the amount of stimulation it was receiving; soon enough, they would be dripping all over the place, but for some reason they didn’t really care all that much about that.

No, the only thing in their minds was the need to grow, not even to pleasure themselves; sure, that they had one another there at their disposal was fine and all, absolutely fantastic to a certain point, but the main drive keeping them going was this incessant desire to become bigger. To grow taller, thicker, curvier, with plumper busts and fuller butts, with hips that would let them hip-check trees off their roots and sloshing that would cause deafness in whoever heard it. All they could think of was how they were out in the backyard and yet only occupied a frankly pitiful amount of it, rather than the whole thing, rather than looming over their whole house as their growth became unsustainable and caused them to explode outwards with even more size. And seeing as how their bodies seemed unwilling to stop, there really wasn’t any excuse for them not to do just that; after all, who was stopping them? Who was telling them they couldn’t just outgrow everything?

It was such a liberating realization that it shouldn’t have come as a surprise that the first thing their bodies did as a reaction to it was… grow. Several feet, in fact, almost as if the two women coming to that understanding had released some kind of pressure valve and allowed their true selves to shine through, even if it was nothing more than a tainted drink polluting their veins and wrapping their physical forms; then again, considering what kind of transformation they were undergoing, “tainted” might be going a bit too far. They weren’t growing disfigured, just bigger, with the disproportionality going to just the right spots for it feel exceedingly arousing: rounder, fuller breasts, plushier, pudgier butts, hips that flared out and outgrew any door in existence, all of it packaged with a body that itself became so much taller than it used to be that both women were very much convinced they wouldn’t be able to stand up properly ever again; not because they couldn’t if they really tried, but because it’d just make them too horny to keep going without collapsing into a heap again.

Thankfully, being “stuck” on the ground as they were, they didn’t need to worry about such things; in fact, with nothing to stand in their way, they could focus exclusively in getting as much enjoyment out of this situation as they could, which of course involved getting their grabby little fingers onto as many curves as possible. Their only regret was that the drink didn’t give them extra hands to work with, though then again, if it had, it was doubtful that they’d be able to remain conscious from the sheer stimulation overload they would no doubt be on the receiving end of. Still, two hands were more than enough to thoroughly enjoy everything one another’s bodies had to provide, and as both Heather and Stella continued to grow, the list of opportunities only got longer and deliciously more detailed.

Wouldn’t take too long before their house was being threatened by both of their burgeoning selves, their paws occasionally crashing through a section of the wall or shattering a window pane, not to mention the groaning of plaster and wood whenever they rolled around too close to it for comfort. That said, why exactly should they care? The thought that the transformation might very well be temporary didn’t really cross their minds, nor the idea that they might have to go back to an existence where they could live inside closed walls; as far as either Poké-gal was truly concerned, this that they were experiencing would be their true selves going forward, and any concerns they might’ve had about lodgings and home ownership before was now entirely moot and unworthy of having time spent thinking about it. They were better now, better than houses and small spaces and tight confines; they were bigger, curvier, much too gigantic to be contained by a simple domicile, and judging from the way the pressure inside their bodies was intensifying, this was only going to get worse (better?) as time went on.

Indeed, their previous home wasn’t fated to last for much longer, especially not after Stella and Heather both decided that they should actively try and get rid of it once they grew big enough. With breasts smushing against one another and their arms struggling to reach any part of their lover’s body that wasn’t either ass or tit, all that was left was for them to start rolling around even more in the hopes of feeling the weight of their forms on each other other, to permit their curves to hug themselves and their counterparts through flagrant abuse of gravity and their own elasticity. On the one hand, it did provide for the kind of stimulation that left them unable to speak properly thanks to how harshly they moaned out in reflex; on the other, it reduced what used to be a perfectly serviceable family home to little more than shattered foundations, glass shard, bent planks of wood and the occasional pile of rubble. Then again, neither of the women particularly cared about what happened to something that, by that point, was smaller than they were; if they bothered to get up, they could’ve easily boobhated their own roof, and if that took place, there was no doubt it would collapse right away anyway.

That said, if they had bothered to get up and look around, they would’ve noticed they weren’t alone in their expansive journey. After all, the drink that kickstarted the entire process had just hit the stores, and being both commercially available and heavily marketed meant it had found its way into every home in their neighborhood. Either through some divine ordinance or sheer luck and serendipity (or perhaps because it was a pleasantly warm day that invited everyone to head outside to enjoy themselves), Heather and Stella hadn’t been the only ones who thought to savour this new flavoured drink, and they certainly weren’t the only couple who realized what it did to their bodies and deliberately played into it. In fact, an argument could be made that they were underachieving in the size department; being so busy with pleasuring one another, they hadn’t actually gone back to drink more of the tainted drink, limiting just how much they could truly grow, while others nearby had absolutely no such limitations imposed on them.

Of course, “limiting” was very much relative when it came to them. One could hardly call their bodies “limited” when they had outgrown their house in both height and sheer volume, when each of their breasts had become heavy and large enough to flatten long-haul transport trucks just by being dropped on one, when their asses had grown to such a point that they could properly flatten a small ship if one of them tripped onto it. It was excess in its purest form, and the two gals wouldn’t have it any other way; their only regret, once more, was that their arms were simply not enough to properly handle everything they had on offer, though this was easily fixed by just throwing themselves at each other and letting their supple selves handle the rest.

It was as if they were made of gelatin, their softness working very much in their favour as their curves melted and moulded into one another, no longer requiring the tender touch of slender fingers in order to provide the best possible stimulation; not only that, but the drink seemed to have done quite a number on their sensitivity as well, with each inch that was touched upon feeling like a whole mile of nerve endings flared to maximum capacity, all of it feeding back into two brains that were already struggling to deal with everything happening around them. Both of them quickly fell into a fugue state from where they wouldn’t come out of for… quite a while, to say the least, both as a self-protective measure with their minds shielding themselves from the overwhelming pleasure, and, paradoxically, as a way for them to be able to enjoy themselves even further; after all, if all control was handed over to their lower functions, the rest of their brainpower could be focused entirely on experiencing every moment to its fullest.

At least, that was what they assumed, in some far-off corner of their minds that yet retained the ability to think. The truth of the matter was far simpler: they were horny, too horny to think straight, and their brains had to adapt somehow. That they chose to do this by deliberately shutting down any “unnecessary” thought processes and throwing both Poké-gals straight into a pit of their own depravity was probably indicative of something, but neither of them were in any position to pass judgement on that; they were slightly too busy trying to push their hands into soft, pudgy breastflesh or attempting to reach around to grab at asscheek to really do anything else.

The drink really was strong, considering that Heather and Stella had only really taken one or two sips and yet they were still growing after several minutes, past the point where they were larger than their house and big enough to appreciate the collection of other giants being born all around them. Some of them were absolutely colossal, far bigger than they themselves were and most likely overdosed on the tainted drink, casting a shadow over everything around them and looming over so many of their peers that it was doubtful they were even on the same level anymore; some were as gods, their heads reaching into the sky and breaking through the few clouds that dared to stand in their way, roaring and murring and purring and growling and a whole host of other, universally undignified noises that came out of their throats. Cocks, tits, balls, butts, all of it was on proud display for the whole world to see… a world that seemed to have been taken by storm by this odd, entirely inoffensive-tasting sports drink.

For Stella and Heather though, none of this truly mattered; the whole world could be dead for all they truly cared, as all they really needed was one another. One might be forgiven for thinking that such an explosive growth spurt would be so fundamentally sexually charged that it would overload their ability to feel anything other than raw, carnal arousal, but surprisingly enough, both women were having plenty of fun simply enjoying each other’s warm, filling presence, even if their bodies did work overtime on their own to improve on the experience by having them rub up and squish against one another. Sure, there were titans out there that were far bigger than they were, but did that really matter when they had each other right there? When all they had to do was open their eyes and, with some minor work to get boob out of the way, they could stare into one another’s soul for hours on end, letting the other know just how deep their love ran? It almost felt silly to worry about size competitions; let others concern themselves with setting and reaching arbitrary goals, the two Poké-gals already had everything they ever wanted.

That didn’t mean they weren’t going to enjoy it to the fullest extent though; they had grown into about twenty-foot giantesses with tits for days and a dumptruck of an ass each, to say nothing of the egregiously curvaceous thighs they had adorning them, or the just right amount of pudge on their bellies, purely for the sake of being grabbed, kneaded and massaged. It was a far cry from Heather’s more athletic physique, and something that Stella never once imagined she’d be capable of putting on for show, but here it was now, as real as anything could be, and right there at their fingertips. It was so easy to just lose themselves, to have their hands fly from one spot to another on either their own body or that of their lover’s, to have each digit find new and improved ways of messing up the pleasure centers of their brains with how much of an electrical discharge they could trigger with so little work; occasionally they would stop moving, ending up either on top of one another or directly side-by-side, lost in one another’s eyes even as they struggled to filter out an outside world that grew increasingly noisier and far less respecting of their privacy and personal space.

Clearly, something had to be done. Heather and Stella didn’t want to just grow for the sake of it, but clearly, if everyone else was going to keep interrupting their moments together, they had to do something about it; and with all of those colossi all growing increasingly bigger and faster, the very Earth itself shaking underneath the emergence of a brand new race of soda-fueled giants, the two women had to take drastic efforts in order to truly escape this cacophony. Thankfully, they didn’t need to rely on any more cans of that drink, or on finding whatever chemical plant produced that clearly abhorrent genetic slurry; they had one another!

Or, to be more precise, they had their breasts. They’d been doing a good enough job of ignoring all of that sloshing emanating from those two enormous orbs they both sported, good enough that sometimes they even forgot it was there; however, now that they were dead-set on a finding a way off that cramped spot, and into somewhere else where they could enjoy themselves without having to worry about pretenders trying to intrude upon their private time, suddenly all of that running milk felt a lot more appetizing than it did previously. Even better, both of their busts had grown so large that they didn’t even need to take turns suckling on one another; with some minor squishing and pushing around, they each found their way to a teat at the same time, and with very minimal squeezing, the cream began to flow.

To call it sweet was an understatement; the flavour was almost offensively saccharine in its sugar content, and were it not for the two gals being so deep into their own arousal that select parts of their brains were shutting down just to make the experience more palatable, they might’ve recoiled at the extremely strong taste. Instead, they both let loose a series of groans that were very quickly muffled by the gouts of milk erupting into their mouths and down their throats, sounds that only egged them both on further as they worked the tit they were drinking from until gallons of the delicious cream within flowed about as easily as water did. It was the stuff of dreams, of fantasy really, the kind that existed only in their private hours behind locked doors, but it was real then, and it was far better than either of them could’ve ever expected.

In between the taste, the sudden size spurt, the outgrowing of all those titanic sex beasts around them until they were little more than small dots off in the distance beneath them, it was hard to really get a bead for what they were supposed to feel: lust? Arousal? Something beyond and yet related? Bliss, perhaps, was the closest they could get, and even that felt… insufficient somehow, though they couldn’t quite put their finger on the reason why. Then again, like most other things, it ceased to matter past a certain point, because nothing else other than themselves was important; not cities, not other people, not the local geography, certainly not the milk after they had their fill. No, they had something far more meaningful, far more valuable than any of those things, something that would allow them to carry on forever if need be, drunk off of it, fed by nothing more than it, and all the more happy for it.

They had each other.
