And how couldn’t he, since it was the single best thing he had ever experienced in his life? The only reason Niz had stopped breathing in the gas before was a combination of apprehension at it being the first use, wanting to surprise his partner and just the tiniest smidgeon of fear for what his neighbors might think; now that the first two things were taken care of, the third wasn’t nearly big and powerful enough to intimidate him into taking even the slightest amount of precautions, resulting in the once-diminutive Niz happily huffing the growth agent until his body began to break through the walls, ceiling and even floor! There wouldn’t be a lot left of their apartment by the time they were done, but that hardly mattered considering that they wouldn’t need an apartment by the time they were done; thoughts of practicality or home ownership weren’t the first ones to make themselves known when the mental image of himself as a giant was all the Kig Yar really needed to keep going.

So… he kept going. He kept taking long, deep, greedy breaths from the gas canister, even the air became thick with dust and rubble, even as the foot that had breached through the front door of his home did the same for his neighbor on the other side of the hallway, even when his bent knee punched a hole through the ceiling and toppled the large sofa that the tenant above him kept in the middle of their living room, for some reason. He kept breathing long after he should’ve stopped, and only really put an end to it when he couldn’t hold it back any longer; he had to moan. It was a necessity, a visceral desire that made him feel increasingly restless for every second he spent not doing it; he had to tell the world, had to let everyone know how unbelievably good it felt to grow into a giant, even if one made mostly out of compressed air.

So he did. He opened his mouth, let the nozzle drop from it, and let loose a sonic blast so powerful that the windows in the couple’s apartment shattered into tiny shards of glass, along with those on the rest of that side of the building once his vocalizations were free to criss-cross through the air outside. He moaned loudly enough that Za’Vark went temporarily deaf just from the impact, his ears ringing as the sounds became muffled; loudly enough that every single person in the apartment block, and everyone in the blocks next to theirs, had their eyes open wide if they weren’t already. This was the mating call of some unfathomably massive creature looking for someone to mate with, and it wouldn’t be more than five minutes before the first emergency sirens reared into action, informing all those who heard them that they were supposed to be out of earshot the day before.

As the evacuation efforts began in earnest, so too did the two lover’s intimacy reach new levels, especially once the Sangheili noticed the macro gas canister was right there on the ground next to him. Not a lot of things that could be done with it that didn’t involve completely relinquishing control of oneself to the glory of growing, and Za’Vark wasn’t about to rack his brains trying to find an alternative; after all, with Niz already well on their way to outgrowing the building they were in, inflating his own body was nothing if not a precautionary measure, what with him having to protect himself from the rest of the structure once it inevitably came down on them… or so Za’Vark chose to see it. There were absolutely no thoughts in mind regarding the excessiveness of it all, or the rampant self-indulgence that was about to lead them straight towards a strike team armed with tranquilizers, absolutely not; just personal safety and zero arousal whatsoever. This was precisely why he didn’t moan as loudly as he could once he tasted the gas himself, breathing it in through deep mouthfuls that bulged his throat out, almost like he was actually drinking something; he merely moaned powerful enough that Niz knew what was going on, lest the Kig Yar try to steal the macro gas away.

The effect were anything but subdued though; as much as the Sangheili might’ve tried to pretend to convince himself he was just doing it for the sake of keeping himself safe, it was hard to deny how fantastic the growth itself felt, especially since it was his first time and he had very little frame of reference beyond his swollen arm. It was utterly indescribable, beyond perhaps the realization that it was, indeed, exactly like he always expected to be, despite the obvious impossibility of reality living up to fantasy; everything, from the sense of pressure, to the shift in perspective that came with his body burgeoning outwards, even the “looming fantasies”, as he liked to call them, they were all there… and they all helped him along whenever the slightest hesitation dared to show itself, giving him the power and determination to either ignore his doubts or outright stamp them down, plowing through regardless of how dangerous it was to him, to Niz, to everyone around the two.

Luckily for the couple, their apartment building was empty by the time they grew too big for it. Despite the large air content of their new bodies, it was still mass that was being added to them, to say nothing of the sheer size of their forms after a short while. Ten minutes was all it took in between Niz kickstarting their final ascension and the floor giving up the ghost, causing them to plummet down towards the ground floor while taking everything in the way along with them. Surprisingly, it didn’t really hurt; presumably, their bodies were of such immense size and power already that even something like falling directly down through five stories barely registered anymore, which itself only served to further entice the two to explore their new selves, doubly so given that they had plenty of room now! Without having to worry about walls, doors or anything other than the large amounts of empty space they carved out for themselves, Niz and Za’Vark were free to roll around while trying to find the most comfortable position to start engaging in their most favorite of activities: rutting like animals in heat.

The building wouldn’t last much longer past that point. Oddly enough, neither of the two really knew how to proceed, even though they had played out size kink scenarios before; they always involve size difference to one degree or another, and while the two were a good five to ten feet apart with Niz on the lead, it hardly seemed to matter given the scale they were now operating at. They had just torn down a building with their reckless disregard for their own personal safety, so that sort of distance really only meant that Niz had to slightly lean forward in order to plant a smooch on his better half’s forehead… well, after they were done doing something far more gratifying, that was.

With no real plan on what to do, it fell down to muscle memory to do what it did best, and the couple surrendered themselves to their own bodies, focusing entirely on savouring the experience as best as they could as instincts took over and even more walls were torn down. They were surrounded by enormous clouds of debris as the large structure they were still inside of crumbled into a large pile of wreckage with each tumble they took, each roll they executed, until it began to implode from the sheer lack of structural integrity; while some of the outer walls yet remained, there wasn’t a lot that they could do when the insides had all been gutted, leading to the remaining apartments caving in from the very top all the way to the bottom, showering the two lovers in such a thick layer of detritus that the only reason they even survived at all was the reason it happened in the first place: the very same size that allowed them to stand up from the wreckage and put themselves on display for all to see.

It was anyone’s guess why or how they both had that idea at the same time, but it just felt right. Just as the building came down, so too must they come back up, both in order to play into their long gallery of giant-based kink play and to reaffirm to themselves that this, this thing they were experiencing, it was real. It was happening, right there at their fingertips and all around them, not just as an imagined scenario behind four walls that didn’t even exist and in the privacy of their own bedroom. Now, the whole world would be able to see them for what they were: glorious, unstoppable behemoths who could flatten anything thrown at them with a single foot, even if they weren’t technically that big yet. Logic and concern for logistics hardly mattered though, not when they were taller than most of the structures around them and covered in the dust of the one they had just destroyed, not when they had one another to wrap their arms around and press into a kiss with, not when the light of the sun shone off their bodies in all of their splendour… and made them feel slightly odd, all things considered.

It was a twinge of something else amidst the ecstasy and rapturous glee that permeated every inch of their being, something familiar and yet distinct that evaded capture by their minds and resisted proper definition. Both the Sangheili and Kig Yar knew that it was important, but in their state, could hardly dedicate enough brainpower to figure out why that was; even when the effects of it began to make themselves known, it took them a few minutes to figure out just what had happened.

Neither of them really gave much thought to the fact that they were technically filled with a kind of extremely expansive gas. Neither of them paid much heed to the fact that it was quite sunny outside, and pleasantly warm to booth. And neither of them were that well-versed in fluid dynamics or chemistry anyway, so even if the two sides of the plus sign were well and truly present in their minds, they’d probably not figure out what was supposed to go on the other side of the equation until it was too late to do anything. Heat plus gas equalled expansion of volume, and their bodies would be no different, causing the pressure the two of them felt within them to skyrocket the longer they were exposed to warm sunlight; of course, this only meant that they were unable to think straight, or even gather the willpower needed to do something about it, leading to even more exposure, more warming, and suddenly the two lovers were struggling with extremely disproportionate growth again.

If their forms had stabilized beforehand, even after giving themselves extra doses on the outside, now they were back to misshapen, even if just barely at the beginning; maybe a little more bulging to the biceps here, a tad more to the legs there, an extra to their package sprinkled into the mix, it was all minor stuff that eventually normalized if they just ignored it for long enough. But as the pressure continued to rise and the macro gas they consumed continued to heat up, there was no denying that everything they had already experienced so far had been naught but an appetizer compared to what was to come… and yet, neither of the two could really bring themselves to care; if anything, this just made them more horny and willing to cross the line for the sake of indulging themselves, a line that Niz in particular was going to abuse for fun and profit as soon as he figured out where the canister had gone to.

It took some digging around in the rubble before he found it, and even then he couldn’t be sure that it wasn’t seriously damaged until he carefully extracted it from amid the literal tons of debris it was buried under. Carefully keeping Za’Vark at bay with one foot as the Sangheili tried to resume their ministrations, the Kig Yar instead brought his full attention onto the tiny little metal cylinder that, by that point, he could barely even pick up with the tip of his fingers; it was so unbelievably tiny, and yet so powerful at the same time, so inconsequential, yet so magnificent in the promises it made. He knew, at that point, just what he had to do, and while he still gulped and fretted about it, knowing that it would end up potentially doing more harm than good, there was no turning back; he had to take the rest of the gas.

Of course, he wasn’t about to do it the same way he had before, given that the hose… probably didn’t fit in his mouth anymore. No, better than he just throw the whole damned canister into the air and then catch it with his tongue like it was some sort of sweet treat, before crunching down on it with a single tooth and releasing a surprisingly large amount of gas that was still pressurized inside of it; it was enough to get his cheeks to bulge and some of it to escape through his nostrils somehow, but in the end, he managed to keep his mouth shut and gulp it down, triggering what he believed would be his greatest growth burst yet… and would, indeed, be the greatest spurt he had ever experienced.

What Niz failed to notice was that the gas filled up his mouth as it was at the time: enormous and attached to a head that topped out a body that was very close to eighty or so feet in height. It wasn’t the same trickle that it had been before, when he was still stuck inside of his room, nor was it a mouthful for when he was still so tiny that he fit inside apartments; rather, it was a dose of growth agent so enormous that even his brand new, colossal frame had trouble swallowing it down, and as soon as that realization hit him, far too late for him to actually do anything about it, was when the Kig Yar frantically tried to share some of it with his partner, as the truth of it slammed right into him like a high-speed cannon: he had just robbed Za’Vark of the opportunity to feel the same growth as him because of his own greed.

Niz figured it’d be best not to try and apologize, but instead attempt to make amends as soon and as quickly as he could, for nothing else would be acceptable. So taken by his desire to grow, the now-larger of the two hadn’t even stopped to think about whether or not he was stealing from his better half’s experience of their own ascension, being too worried about his own to really think about it. Now that he felt the growth spurt welling up inside of him, the gas suffusing every inch of his lungs and ready to be dispersed throughout his body, he knew what a colossal mistake that had been, just as big as he was about to become in fact; the only thing he could do to make it up to the Sangheili, even if they themselves didn’t know what had happened, was to turn around, wrap his arms around him, and lock the two into a deep enough kiss that their mouths formed a seal. Only then could Za’Vark share in the bounty… or, at least, that’s what Niz hoped would happen.

The heavens were feeling merciful to them that day, and indeed the second chance that the titanic Kig Yar was hoping for was given to him after he atoned for his sin; Za’Vark’s reaction to the kiss might have initially been the same as ever, with their eyes going half-lidded and their grip on Niz’s back tightening as the two grew closer to one another, but as soon as they tasted the sweet aroma of the macro gas wafting from the Kig Yar’s breath, they too would go wide-eyed and begin to excitedly moan at the prospect of being given another, presumably final upgrade in size. It was all that the two could ever want: themselves, wrapped up and unwilling to let go of one another, sharing a single intimate moment that would let them burgeon outwards and consume more and more of their surroundings the longer it was allowed to last, as their bodies’ store of the growth agent was shared between the two and enhanced the already insane amounts of inflation they were experiencing. Not only did their former apartment block get destroyed thanks to this brand new growthsplosion, but those around it as well, with claw and tail and leg and chest alike barreling through solid concrete and rebar, destroying whatever happened to be in its way as the two lovers grew to unmatched heights, bigger than the biggest of hypers, more powerful than the most magnificent of macros… or so they assumed, at the very least.

The truth of the matter was somewhere far below where the two placed themselves in the great chain, but that didn’t make them any less of a threat to their surroundings; if anything, it was precisely their overinflated sense of might and self-importance that made them so dangerous to everyone and everything around them, seeing as it wasn’t likely that they’d hold back on showing the world just how “perfect” they were or how “glorious” their bodies happened to be. This was a lesson that the few folks who hadn’t evacuated yet learned the hard way when the growth spurt they believed would just “end on its own”, or whatever random reason they used to justify not getting up from their chairs, ended up destroying the very building they refused to vacate, leaving them scrambling to try and find the nearest exit even as it was being filled up and occupied by the two lovers’ burgeoning, bloating bodies.

Neither Niz nor Za’Vark were really aware of this, of course; their existence was one of pure pleasure, one where they needn’t worry about the concerns of petty mortals, especially after they reached a point where their frames were so immense that they loomed over every structure near them. It didn’t occur to them that they were literally full of hot air, and were thus about as sturdy as a balloon with an extra-thick layer of rubber, but that hardly even mattered when they could still stamp down on a car and reduce it to a thin, metallic disk without even bothering to look in its general direction; in fact, so deep were their delusions of grandeur that they failed to notice when the light of the sun finally began to work its magic on them and cause them to grow to even larger sizes!

They really should have though; seeing as their bodies were so thoroughly filled with the macro gas, the sudden increase in pressure that made them feel like they were ready to pop should have alerted them to the fact that something was deathly wrong and they should do something about it. Instead, both the Kig Yar and the Sangheili instead decided that the best thing they could be doing was trying to get on their feet, something that was made remarkably more difficult than it should be by virtue of neither of them wanting to let go of the other if they could avoid it; a romantic sentiment, perhaps even enviable, if not for the simple fact that it also caused them to trip over and flatten several housing complexes and multiple vehicles, to say nothing of the amount of damage being wrought on the pavement, large sections of which had already collapsed to expose the piping underneath it. Thick spouts of water flooded the area around the couple’s ascension site, serving only to egg them on further as their forms were given a nice wash, a good clean, and a resplendent new sheen as the water droplets clung to their stretched skin.

If they were both told that this was a shared dream they were having based entirely on their mutual kinks, they would probably be ready to accept that it was, but wouldn’t really do anything else; if it was a dream, it was one they wanted to prolong as much as they could, keeping it going until they could explore every single lewd thought that they ever shared with one another in vivid, lurid and surprisingly tactile detail. It was simply too good to be true, is all; with this being the sort of scenario they played out so often in the privacy of their former (?) home, how they could ever accept the fact that it was real, and not just some collective hallucination brought on by the gas they huffed down? For all they knew, it was an intoxicant, and they’d been tripping for the past couple of days.

Then again, even if that was the case, why stop now? Why not try and fail to stand up multiple times, too worried about maintaining physical contact and rubbing their bodies against one another to really do anything else at all? Why not carry on destroying everything they touched as they rolled over their local city block, prompting emergency evacuations and the intervention of emergency services? It only served as a reminder of how massive they were, of how imposing and dominating their bodies happened to be, and how much they still had to gain now that the sun’s warmth was finally giving them what they truly wanted… and what they truly deserved. After all, the gas within their bodies had yet to heat up properly, so clearly what they had now was just a fraction of what they could truly be; therefore, the best possible course of action was to try their best at disentangling themselves from one another in order to bask in the glare, to absorb as much of the sun’s rays as they could, feeling as the air filling them began to expand in every direction as its constituent molecules were agitated further and further.

Groaning and creaking filled their ears, as if two enormous balloons were being stretched to capacity and beyond over and over again, always so close to their limit yet never quite reaching or crossing it; it made for a wonderfully transcendent experience, at the very least, especially once the two of them started to feel the back of their heads digging into the ground or their heels carving out whole trenches in the street and out of whatever building happened to be in their way. If anyone were to ask them what they felt at that point in time, they’d only be able to reply with a long, drawn-out moan and mindless begging for more, even as their forms continued to burgeon outwards, putting them in serious risk of injury if they happened to hit something that wouldn’t budge.
