They wouldn’t though; nothing that could feasibly be in their way would ever be able to stand up to their growing might, not the cheap building materials that made up most of the apartment blocks there, not the asphalt, not even the occasional stone wall separating bits of greenery from the rest of the urban jungle. Theirs was a world that was free for the taking, open for them to swell into, to grow and barrel over, even when that technically wasn’t even their original intention; it was hard to hold onto simpler goals when the world gave them so much more than that, when their physical bodies felt like pressurized canisters themselves just begging to pop or, barring that, take up increasingly more room.

And more room they took, as the sunlight did its magic and carried on forcing the gas inside of them to expand, taking the rest of their bodies along with it. The process was incredibly disproportionate, just like the original burst of size courtesy of the macro gas back in their home, and given how the sun wasn’t really going anywhere, it was doubtful that it’d stabilize any time soon; indeed, minutes passed with no sign of the sudden expansion stopping, with both Niz and Za’Vark writhing under the glare of the sun as their minds struggled to even begin to comprehend what was happening to their bodies. Arms bloated far in excess to the torsos they were attached to, with the excess gas pouring into their torsos and causing them to swell up like balloons before the extra pressure was distributed… but then their legs would overshadow their bodies, before their tails did the same, and the whole process started all over again with random starting and endpoints. Theirs was a fluid form, one that existed at the mercy of the substance that made them larger than most buildings around them, and while the two should have been worried about the implications, they were too busy playing with themselves and one another to really notice how much their frames were being pushed to the limit.

Be it with their hands holding onto a cock that was of immensely variable length depending on how much of the heated gas was being pumped into it, their knees or legs rubbing up against an equally-gigantic set of nuts, or just the two of them turning to the side to enjoy a prolonged, deep and incredibly exotic tongue-filled kiss, given how even that appendage was eager to receive part of the growth spurt, the two giants had surrendered to the sheer excess of it all. An experience that had once been the exclusive purview of their lewd little minds had been brought to life and handed to them on a silver platter, and they’d be damned if they weren’t going to make the most of it, especially if it all turned out to be temporary; not that they were really thinking about time limits, of course, given that their minds were far too preoccupied with simply enjoying each passing moment as it stretched into infinity.

Their bodies, too, were stretching quite a bit, though not as much as their libidos. With evacuation efforts well underway, it fell to local emergency services to try and do something of worth to stop the two burgeoning colossi growing in the middle of their fair city, all while the access roads were clogged up by escaping vehicles and the streets were choked by those scrambling to the nearest emergency bunker on foot. There wasn’t much else the crowd could go but hope that the authorities fixed this problem; macro-level rampages were always incredibly complex and nasty affairs, often the cause of years of litigation, and if the day ended without anyone getting hurt, then it would be a bona fide miracle, no exaggeration there. Unfortunately for everyone involved though, the fact that neither Za’Vark nor Niz were registered as being hypers, much less macros, response was significantly slower and far less coordinated than it could’ve been; without an established plan of action, no one involved really knew what those two were capable of, forcing them into a “wait and see” approach that left everyone on edge and waiting for any opportunity to strike.

Given the sort of noises coming off of those two though, it was hard to tell just what exactly they could even do; the creaking and groaning were, if nothing else, far too reminiscent of plastic being stretched, like the couple were actually made of balloon-grade rubber rubbing against itself, while the continuous growth spurt they were undergoing was so oddly disjointed that not a single person present really knew what to make of it. In many aspects, it was an entirely novel incident; what were they supposed to do if they had no clue what either of those two giants were capable of?

Regardless of whatever they came up with, those giants weren’t going to stop just because others wanted them to. As their forms ascended to break through the hundred-and-fifty foot mark, rapidly approaching the big two hundred, the disproportionate aspect of their inflation began to smooth out; perhaps the macro gas inside of them wasn’t hot enough to keep expanding at a ludicrously exponential rate, or maybe their skin itself had reached some sort of limit, but whatever the case, they found themselves swelling in all directions, reasonably at the same peace, with their forms returning to a more default state. They were identifiable as Niz and Za’Vark again, at the very least, even if they had become big enough to step on a building and flatten it without even breaking a sweat… something that they were both suddenly very keen on trying.

Getting back on their feet was significantly harder than it was before though, with the both of them having to exercise caution not to trip over thanks to their weirdly-shifted center of gravity. They may be enormous, but given the gas content of their bodies was significantly higher than the meaty bits, however that was supposed to work, they found themselves to be far lighter than anyone of their scale should be, thoroughly violating the square cube law for their own fun and profit. It made moving simultaneously a chore and quite a bit of fun in and of itself, as while they had to exercise caution not to take steps that were too wide, they could also reap the benefits of being, effectively, two massive parade balloons with perfect control over their motion, even going so far as to step on nearby apartment blocks without them crumbling into bits.

Needless to say, this left onlookers flabbergasted at how this was even possible, with the police officers especially wondering whether they could even use tranquilizer guns without accidentally “popping” either of the two (or worse, both); it was a surreal sight to be sure, having two rampaging, marauding macros who should be turning the whole city into a pile of wreckage instead harmlessly and effortlessly float about as if they were weightless. It made very little sense, it defied all known data on macro-level hypers, and frankly, it was now officially far above the paygrade of just the local fire department or police station; this required governmental intervention at some level.

Meanwhile, the Kig Yar and their Sangheili partner were, for lack of a better word, frolicking about in their new domain, figuring that the best way to truly introduce themselves to the world would be to simply move through it and put their glorious forms on full display. It was exactly as enticing and arousing as all of their “kaiju versus city” roleplaying sessions, and with none of the bothersome destruction to ruin the fun with potential casualties; just the two of them and a whole host of buildings they chose to believe were empty, even as the tiny ones ran between their feet in the short openings they were given. Occasionally, one of them would feel a tiny pinprick, courtesy of someone trying to open fire on them, presumably with a non-lethal tranq dart; despite their skin being stretched taut and their insides being predominantly stuffed with some kind of growth-inducing gaseous substance, however, there was no pop, no rip, no ending note where their bodies would immediately begin to deflate. Instead, they just… kept going, as if nothing ever happened, until they simply began to ignore these little stings whenever they dared to show up. Besides, there was a bigger problem to deal with.

Both Za’Vark and Niz were happy to accept the “fact” that their bodies had stabilized. After the growth spurt left them as positively titanic versions of themselves, with both being easily over two hundred feet by that point, the fact that they had stopped growing (or at least slowed down enough to count as the same), as well as how their proportions had normalized once more, convinced them that the worst was over. They were still out in the sun, but whatever that gas inside of them was and how it operated, then surely it had reached the endpoint of its effects and they were now running on borrowed time; eventually, they would each other in their arms, do something silly and then the whole city would be covered in their spunk after a small tornado was created by the gusts of wind produced by them… emptying out, so to speak.

What the couple didn’t account for, however, was that their second guess might actually be right, that it hadn’t been the gas that stopped expanding, but their bodies which had reached a limit, unable to stretch any further for some unknown reason. In reality, the heat was still working its magic on the macro gas inside of them, still agitating its molecules, still making it so that the substance attempted to fill up a larger and larger amount of space; but just as it attempted to push the boundaries of the two roomies’ bodies even more, suddenly it found itself being pushed back as the pair of giants had, put simply, grown too much. A barrier was erected, preventing them from going any further, whether by design or by some genetic happenstance, and now there was only one way that things could progress: more pressure.

It was easy enough to ignore at first, even if they really shouldn’t have. Both the Sangheili and their Kig Yar partner were happy to believe that it was just a regular part of turning into a macro, that it was something that would “go away” on its own, even if they didn’t formulate those thoughts exactly with that wording. It was secondary, if even that, and their main concern was to enjoy themselves as the colossi they had become while they still had the chance for it; but their lack of care didn’t make it any less serious, and indeed it was precisely their unwillingness to pay attention to it that allowed the rising pressure to sneak up on them and suddenly take them by storm after it reached a critical point, both Niz and Za’Vark becoming aware of how tight their bodies felt at about the same time. With their eyes going wide and their perpetual smiles drooping, the two mates looked at one another, as if to confirm that the other had also felt it, with panic soon rising in equal measure as they confirmed it… though not necessarily for any sane reasons.

For anyone else, it might’ve been a sign that their bodies were about to give up and explode, courtesy of them being literally filled to the brim with gas. To the two giants there present however, it meant something far different: it meant that they were about to finish. Admittedly, this wasn’t exactly the case; they were very much in danger of injury if they didn’t do something about the vast quantities of growth substance trying to break through any opening in their bodies, but given their experiences in the previous day, it was hard to blame them for coming to such a faulty conclusion. Besides, it led them down to the same solution: clearly, they had to make the best use of their limited amount of time and rut like animals while they were still gigantic. Not only would that let them get the most bang for their buck, but the explosive finale would be… something else, that much they were certain of.

Only one way to fix it: fucking. It was the same thing they were going to do anyway, sure, but now they actually had a time limit imposed on them by virtue of them being giants in the first place and the means they used to get there. It was nothing short of distressing that the two of them had to be suddenly confronted with the reality that it was all ultimately temporary, that despite their fantasies they were still just regular-sized individuals who just happened to be given an enormous size boost courtesy of a gas that would, inevitably, seep out out of their bodies. It made things suddenly feel far too “real”, for lack of a better word, as if they had just been mercilessly ripped from their personal heaven and forced back into an uncaring, unloving world where they weren’t the divine couple they envisioned themselves as.

Even worse, the pressure was getting higher and higher the longer they waited, until after a point both Niz and Za’Vark began to wonder if their situation wasn’t worse than what they thought it was; surely, if it was just a matter of the macro gas trying to escape their bodies, then surely every inch of them wouldn’t feel like it was blazing, searing hot, and every single ounce of the substance floating about inside of them would feel as if it was trying to escape from their very pores at every waking moment. The light of the sun, its heat, was causing things to quickly spiral out of control, and though the two colossi were slow to reach that conclusion, mostly courtesy of them wanting to remain blissfully ignorant of it, they couldn’t run away from it for too long: if they did nothing to stop it, their expansion would resume, except that time their physical forms wouldn’t keep up with the demand for extra room… and from there, well, best not think about the consequences.

Thus, the only thing left was for them to rut like rabid animals in heat and hope that it fixed things just like it had the previous day. It was harder than expected to get back to one another; with them being so distracted playing giant among the city’s buildings, they had actually walked quite a fair distance away from each other, and as the gas within their bodies continued to heat up, so too did their buoyancy increase until it was genuinely hard for them to keep their balance without tipping over or having their bodies try to float up like a gigantic helium balloon. They hadn’t gone back to the disproportionate bloating, though that was hardly any consolation given that they were turning into oversized parade balloons in far more ways than just one by that point, and if they did nothing about it, there’d be a lot of needles puncturing them from within.

The sounds that came when the two of them finally reached one another only served to accentuate this, with loud, ominous rumbling replacing the softer creaking or the noises of stretching leather that had dominated their ascension beforehand. Neither of the two could really make sense of it either; as far as they could tell, their bodies were still just as organic as before, just stretched out to their very limit, so the sounds didn’t exactly square up to what they expected them to be… then again, they were in position to complain or raise any questions about it, lest they end up wasting too much time and finding themselves unable to do what had to be done: holding each other in the other’s arms, pulling their two bodies together, and then (almost comically) slowly collapsing to one side, ending up not really crushing a set of buildings, but just draping themselves over them, indeed like parade balloons.

They wouldn’t remain that way for much longer though. With their fantasies having been lived out and their kinks stoked with so much fire and fuel, both the Kig Yar and the Sangheili both sported turgid shafts from all the physical and mental stimulation, and given that the gas seemed to have a predilection for improving their packages, it was no surprise that their nuts had similarly bloated to such an immense degree that they were effectively the only thing really pinning them down to the ground; cum ballast, if they ever bothered to come up with a definition, ballast whose job it would be to leave their bodies and pain the city a thick, creamy white in order to make way for all the gas that was sure to come afterwards.

It really didn’t take long for them to reach their edge either; the two of them were so activated that it was frankly nothing short of miraculous that there hadn’t been some kind of release yet, especially given that both Za’Vark and Niz had actually stopped to openly stroke themselves a couple of times. No, they were yet to truly open the floodgates and let their arousal flow in the most literal sense possible, and thanks to that, they were both carrying so much of their densely compacted seed that, by the time it started to churn and their nuts began to clench, they managed to overpower the quaking of their bodies struggling against the expanding gas. There was no method to the madness there, just two giants rubbing up against one another in a desperate bid to get off before their bodies exploded, their erect cocks forced to smush together as they moved up and down against one another, with the two lovers truly unable to do anything other than frotting now that their physical forms were starting to reach the breaking point. Controlling their muscles became harder, even holding their arms and legs in a bent position was starting to hurt, and it took all of their considerable might and willpower to carry on with what they were doing, packing enough force in their motions that even their lightweight forms managed to crumble a few buildings. But, in the end, it was all worth it, because their climax was something beyond their ability to describe.

Their only means of comparison, that being what happened back in their living room in the apartment that had since ceased to exist, was something they both thought could serve as a benchmark; both Niz, who actually went through it, and Za’Vark, who had been there every step of the way, assumed that whatever they ended up going through when they were bigger would just be a scaled-up version of what their neighbors had to deal with. And it may have been just that, for all they knew, but the onslaught of confusing and overwhelming sensations that washed over them when their limit was reached and their bodies crossed the line into climax was of such a magnitude, such a degree elevated above what had happened previously, that to try and put it into words would be a disservice to it as a concept, a crime against the heavens themselves.

Their chins were blasted by twin spouts of spunk erupting from their tips, both of which thickened considerably with each second they passed in open release, until they had to let go of one another and give each other some space just to prevent them drowning underneath the deluge of cum pouring out from their bodies. It was genuinely mind-boggling just how much of their seed was being pumped out, even after their nuts had grown to make it almost impossible to walk without waddling to some degree; countless gallons, outright tons being pumped out of them at speeds high enough to strip concrete off of walls and outright punch through solid rock if need be, turning the immediate area around them into a disaster zone that, far from merely being coated in a thick sheen of virile seed, was instead flattened outright before being submerged underneath a dense layer of the stuff, making it hard for the two of them to even move at all, let alone writhe to their heart’s content. And there was a lot of writhing to be done, given what they were feeling at the time; they had barely gotten through the contents of their balls and already their minds were blank and their muscles working entirely on their own.

But it couldn’t last for too long; eventually, even if did take a couple of hours, their nuts would be emptied, their bodies would reach the breaking point, and all the macro gas they’d been holding back would finally be allowed out into the world. Much like it had happened with Niz the day before, one moment they were pouring out goodness knows how much cum, and the next their bodies were assaulted by an extraordinarily powerful gust of wind being produced by their turgid manhoods, pressurized air firing off from their tips at a temperature so high that it made both of them sweat like pigs after being exposed to it. No wonder their bodies were struggling to hold back against the expansive gaseous substance, it was searing hot, so much so that it vented out of them significantly faster than it had with the Kig Yar before; rather than a long, drawn-out release, the two giants might as well have been giant balloon-like versions of themselves with how quickly they deflated, losing foot after foot as if they were being hit by some kind of shrink ray. Not that they really minded; they were too far gone to think about what was happening to them.

Were they in full possession of their mental faculties, they might’ve objected to going back to being the same-old, tiny versions of themselves that they had done such a great job forgetting about in their short macro rampage, but with the orgasm of a lifetime wracking their brains, they were happy to just shut down all unnecessary thought processes and just enjoy themselves while it lasted, all the way down from their two hundred feet height record and back to whatever piddly little height their “real” bodies had. To say that they were left confused and without bearings would be an understatement, given that they suddenly found themselves floating atop a small lake of cum of their own creation; luckily, the two of them had fallen down just close enough to one another that a few shouts were enough for them to locate their partner… that is, after taking a couple of minutes to recover and come back to reality, to a certain degree.

Actually swimming through the grunk was noticeably difficult, and if not for their minds being so broken that they refused to tell their bodies to stop before hurting themselves, they might just have succumbed to their exhaustion and ended up just floating there doing nothing. But they had to find one another, had to see the other’s face after what had been, by all means, the absolute best experience of their life, had to confirm that it had happened and they weren’t just dreaming. It wasn’t until they were right next to one another, close enough that they could once more throw their arms around each other and feel the warmth of their bodies even through the heat rising up from the thick, syrupy liquid they were swimming around in, that they realized the reality of the situation.

Far from a dream, what they had done had actually happened: multiple buildings were destroyed, a significant chunk of the city was flooded, the storm drains weren’t getting rid of it… and there were emergency responders just outside the cum deluge probably waiting to snatch the two giants after they most likely saw them shrink back down to a manageable size. The one thing they should do at that point was run the hell away and try to lay low for long enough that people would forget what they looked like, hopefully so they could start their regular life all over again.

After all, there was more macro gas left to buy.
