Fluorofalsomide, one and a half milliliters. Difaikline, eight milliliters. Dymthyoline nitrate, five milliliters. Water, twenty milliliters.

Chee combined the chemicals in a vial and stirred until the mixture smoothed. It illuminated its immediate surroundings in radioactive green.

This was the culmination of a year's worth of experimentation. Dozens of failed concoctions that had singed his whiskers and exploded vials in cartoonish puffs of atomic smoke resulted in this--the final compound.

He pushed back his safety glasses and tilted the vial toward his mouth. Chee gathered a few drops on his lips and lapped them off. The syrupy potion had a hint of sweetness, but was otherwise tasteless and odorless.

Chee waited. He swished the remaining contents of the vial and watched concoction slosh up the glass sides. Nothing happened. Something should have been happening. Had he gotten the ratios wrong again? Was one of the ingredients off? Chee waited a few more heartbeats, then tossed his head back and downed the remainder of his elixir.

His heart started to pound and his skin felt too tight. This was it! He'd finally done it! His body throbbed and he purred with satisfaction. A tingling, stretching feeling pulsed through him, pulling every muscle fiber and tendon taut and then stretching them past their limits with a spike of pressure somewhere between pleasure and ache. He was at first drawn-out--skeletal--but with every heartbeat his figure bulked, filling in his newfound size until he began to regain his original slim proportions. His lab coat grew too tight and Chee looked to his forearms as the material bulged and then ripped away to reveal the spotted fur underneath. Then Chee had a realization that if he kept growing with every whoosh of his pulse in his ears, he was going to be too large to get out of his house.

On his hands and knees, Chee scrambled for the stairs, but the rate of his growth increased. By the time he'd reached them, he was too large climb down. The floor underneath him cracked like a matchstick, but didn't give, and he sat up and banged his head on the ceiling. Bits of drywall fell around his face and gathered in his fur.

He ducked his head again but was still too large for the space. With his chest almost touching the floor, the tips of Chee's ears grazed the ceiling and his toes touched the far wall of his lab. Still he grew, body throbbing and tingling all over, until he was curled in a ball and his shoulder blades touched the ceiling.

The floor gave out and he crashed on his hands and knees into the lower level. With the free space, Chee stood, but within seconds he was hunched over again, then crouched, top of his head against the ceiling again. He tried to brace his hand on the wall beside him, but his strength matched his increasing size and he broke through it into the home next to him.

With another, hard throb, he grew several meters and his head burst through the ceiling. Rubble and roof tiles fell around him and Chee stood, demolishing the remainder of the upper level of his home and collapsing half of the connected houses at his sides. The final shreds of his lab coat fell from his body as he emerged from the wreckage and stepped out of the debris, shaking out his fur to dislodge pieces of his former home. Chee sneezed, dusted off his head and face, and looked to the ground below.

Around him, people fled from their damaged homes. They grew smaller beneath him--first the size of one of his fingers, then half the size, then smaller.

Chee's skin pulled taut against his body with a sensation like pulling on a tight rubber glove, then went slack. The sensation became a sound that creaked from his skin on the next pulse of growth, putting him in a constant state of tightness followed by his skin relaxing around him, then stretching again as his body continued to grow. He was chest-height with the terrace houses he'd destroyed and looked over their roofs.


A massive cheetah had emerged from the rubble of the collapsed buildings. Most onlookers below fled from his growing mass lest they be trampled, but several people in the streets remained paralyzed with their heads craned backward, staring up as the cheetah's body continued to enlarge at a steady rate. He shifted his weight and his feet crunched bushes beneath him and his paw pads dented car-sized craters in the ground.


Chee's height allowed him to see farther and farther into the distance. To his right, the city gave way to suburbs, and to his left, buildings huddled closer and closer together into a metropolis. The jewel of that metropolis was a 600 meter tall skyscraper that dwarfed the 200 and 300 meter tall skyscrapers spattered around it. Arousal flushed Chee's body at the realization that he was already half the size of the smaller towers. His cock throbbed and started to stiffen.

Chee shook off the final remnants of his collapsed home and started on his way toward the heart of the city.


_There was the distant was the sound of cracking and crunching, and soon the ground shook with a repeating thud. The people in the streets began to panic. Was this an earthquake? There were never earthquakes in this part of the country.

Those on foot stopped in the street. One person turned, screamed, and drew the attention of others nearby. In unison, people stopped in their tracks, tilted their noses skyward, and stared, petrified, as the figure in the distance approached.

It was at first hard to determine what it was beyond the clusters of buildings, but a pale yellow, spotted figure began to emerge as the entity grew closer. It was a massive cheetah, blue-eyed and approaching fast. Not only did he appear larger as he closed in on the metropolis, but it was apparent beside the buildings that he was becoming larger still. His cock throbbed and grew with the rest of his body, becoming more and more massive--and more and more stiff--with each pulse and casting a lengthening shadow over the city as he closed in on its center. Once he'd reached the city heart, with the tallest buildings, his cock stood at full attention, so huge that the barbs on the tip of his tapered cockhead were as large as one of the people below._


Chee's feet and calves crashed through multi-level buildings like stepping through grass. He delighted in their crunch--like dry leaves--underneath and between his toes, but his attention drifted to bigger and better things. Chee stopped beside a skyscraper about 300 meters tall; he was just over three-quarters of its height.

Chee pressed his hips forward and sandwiched his cock between the wall of the skyscraper and his stomach. Precum oozed from his cockhead, which he rubbed against the building. The skyscraper quaked under his grinding and his barbs raked the skyscraper's concrete walls. Windows shattered and the glass sprinkled his cock like dust.

The unyielding firmness against his cock was everything he hoped it'd be. And rather than the cold one might expect, the building was warm--heated by the sun and the microclimate of the structures below and around. Chee thrust his cock against building and looked up to gauge his height. He was now only a dozen or so meters shorter than the structure.

He pressed into the building again and his newfound strength cracked the concrete under his cock. Chee leaned back to survey the damage as he rutted against the building. He dented the concrete farther and farther until a cock-shaped hole collapsed into the side of the building.

A cock-shaped and cock-sized hole. Chee held the building with both hands on either side, pulled back, and thrust into it. He was large enough that the girth of his cock alone was a few floors high and demolished the barriers between them, which provided a pleasant tingle on his cockhead as he thrust into the structure, farther and farther each time until his hips were flush with the concrete and he was pounding the skyscraper. It cracked more and more beneath his grip and rutting.


Chunks of concrete and massive, people-sized shards of glass rained from the skyscraper. The swarms of citizens on the ground now knew beyond doubt that nothing and no one was safe. In cars and on foot, they fled the vicinity as the massive cheetah masturbated against the building, every motion of his hips thundering another crack of the battered building through the city below.


Chee was taller than the skyscraper now. He shifted, crushing buildings behind him when his tail swung, and rested his chin on its roof. The larger he grew, the faster he seemed to grow. He was suddenly twice as tall as the skyscraper, hunched over it to keep breeding the hole he'd carved out. His cock penetrated straight through to the other side of the building, which remained held together by flexing steel beams on either side. But it couldn't withstand the onslaught much longer. Chee's cock expanded farther with a massive growth spurt that rocketed him to an overall 800 meter height and pushed him to the edge of climax. The bulge toward the center of his cock burst outward, shearing the building in half and halting his pleasure in its tracks.

The skyscraper crumbled around his cock and collapsed to the ground. Cock throbbing, Chee surveyed the city, and reveling in the dozen or so square kilometers he'd already destroyed, and searched for the next target to sate his lust.

He turned to one of the 200 meter skyscrapers. Chee tramped over to it, razing blocks upon blocks of businesses before he came to a stop in front of his target. He bent at the knee and wrapped his hands around the base of the skyscraper. With a tug, he tore the building and its entire foundation straight out of the ground, leaving a gaping hole where it had been.

The building was as heavy as he'd expected a concrete and metal structure to be, and he shifted its weight around to get a better hold on it. From his crouched position, Chee fell backward onto his rear. The buildings beneath him crumbled to dust and his weight quaked the roads, sidewalks, and the ground itself, leaving two craters where his rear rested. The localized shock wave that rippled outward rattled nearby structures and brought many to street level.

Chee couldn't be bothered with that, though. His cock oozed precum, which he smeared along the skyscraper he held with both hands against his cock. He pressed it against the underside of his cock and dragged it up and down the length of it, skyscraper lubricated by his dripping tip.

The tower grew smaller in his hands--or his hands grew larger around it. Soon it took him one hand to carry it, and soon it matched the length--it was just shy of the width--of his cock. Chee was able to wrap his hand around both himself and the building, stroking his top side with his thumb and the bottom with the skyscraper.

It didn't take long for him to build up to where he'd been before the first skyscraper had collapsed. Chee's breathing grew heavier, and with a mewl, he came in a burst that flung ropes of cum out over the city.


The gigantic cheetah's fall into a sitting position had lurched the ground beneath the fleeing citizens' feet and threw them. The macro who had leveled half the city had been panting so hard it was like a storm had hit the streets, almost sweeping away those who were too close for safety.

Then, with a few final, heavy breaths, the masturbating behemoth climaxed. His cum jetted across the sky, shadowing the streets and buildings below just before it splattered to earth. It flooded a few blocks closest to him, sweeping away everything in its path, and coated a dozen or more buildings in a thick layer of pungent cheetah semen that oozed to the ground.


Chee dropped the building beside him--it collapsed in on itself with a loud crunch--and drifted down from the pleasure of orgasm, cock slowly softening. He surveyed the city--the blocks and blocks he'd leveled, where only concrete dust remained; the crater he'd pulled the skyscraper from; and the buildings drenched in his cum. There remained distant specs of cars and those fleeing on foot from the chaos that had spawned in their city.

He didn't know how long he'd fucked the buildings, only that he'd quaffed his compound in the early afternoon and now there were a couple hours before sunset. Chee exhaled a long sigh. A hint of his own musk tickled his nose and he wondered how strong it was to those on the ground.

His pulse pounded hard in his ears and Chee went through another growth spurt. The size increase lurched everything around his sitting figure out of the way, leaving splinters of concrete and asphalt jutting from the streets below--splinters that were nothing more than dirt to Chee.

Judging by the several remaining 200 meter skyscrapers, Chee estimated his height around 1,750 meters. His calculations had determined that even if he consumed the entire flask of his concotion, his growth would level out at one kilometer high, yet still he could feel the pulse of growth within him. It was a miraculous surprise.

Chee purred, rattling the ground below. Lust sated, his attention shifted elsewhere. A pressure low in his bladder made him survey the city around him for a suitable urinal. His eyes fell to a sports stadium. The deep bowl was the perfect size and shape.

He stood from the cozy spot he'd dented in the ground--leveled blocks collapsed into the craters--and made his way to the stadium. Chee looked into the bowl, took his cock in hand, and let loose into it. He watched with satisfaction as his urine splashed into the stadium and gradually filled it--first the field, then the first row of seating, and the next, and the next--dislodging the chairs and washing away miscellaneous abandoned equipment and tools.

His stream stopped just below the lip of the stadium, though a few macro-sized droplets splashed over the edge and flooded out a few vehicles in the parking lot. They drifted several meters in the yellow wash and came to a stop near the edge of the lot, soaking wet.

The devastation his urine alone could cause sent desire straight to Chee's cock. It started to stiffen again and he scanned the area for something he could use to satisfy himself once more. The buildings were smaller and smaller beneath him. Only one was large enough to attract his attention--the 600 meter tower that was the city's most prized piece of architecture. It was just over a third of his current height and three times the length of his cock.

Chee razed several more blocks en route to the skyscraper that dwarfed the others, the shortest of which were now a few dozen meters above ankle height on Chee. He stared down at the 600-meter building that came above his knee, cock at attention and oozing precum. It was a beautiful building--sleek and modern. He wondered if it would stay together longer than the other skyscrapers had.

He lowered into a crouch, wrapped both hands around the building's base, one above the other, and gave a pull. The foundation cracked and rose several meters from the ground, but otherwise remained fixed. Chee braced himself again, wiggled the building's base, and with one big tug that set him off balance, he uprooted the structure entirely.

Chee fell back onto his rear with the structure in his hands. This was the big prize--the last thing the city had to offer him. He turned the building over in his hands and flicked off jagged bits of the foundation; it tore away. With the slab forming the base of the building gone, its guts were exposed from the bottom. The walls within the building that separated rooms and hallways were like a fine mesh.

An idea crept into Chee's mind. This building was special, so it would be a waste to rub it against his cock like he had the 200 or 300 meter tall skyscrapers. Instead, he maneuvered the building until the hole in the bottom was aligned with the tip of his cock. With a slow, curious movement, he brought the building down and pushed the head of his cock against the building's opening.

It was immediately better than rubbing something along his cock. The reinforced inner walls seemed to melt along his cock, wrapping it in the building's innards. As Chee thrust deeper, the skyscraper wrapped around more and more of his cock. He mewled in pleasure while the building continued to wrap around his dick. He sank his cock completely inside of it; the building's base rested against Chee's body. There was a significant amount his cock couldn't reach--yet.

He pressed his hips into the building, then lifted it off his cock several dozen meters and brought it down again. The fine insides that dissolved around his cock shot a pang of pleasure through him and made him throb, eager for more.

Chee used the building as a cock sleeve, bucking his hips into it and panting. The base started to give to the force of being slammed against Chee's body on repeat, and gradually it began to crumble. That wasn't a problem, though. There was so much more of the building to fuck, so each time it lost meters upon meters of height from the bottom, it only blanketed Chee's cockhead with another layer of its soft insides.

Chee slammed his cock into the building again and again at an increasing pace. Each thrust trimmed the building shorter in his hands, dusting his balls with its smashed fragments. Meanwhile, he continued to grow. Chee's cock expanded within the building, breaking apart more of its insides.

Then finally, with one last, hard thrust, and one hard throb of further growth, Chee's cockhead burst through the roof of the building and he came, flooding the city with more thick strings of cum.

He sat there for some time, panting in the afterglow, cock wrapped in the crumbling building's shell, and surveyed his destruction. The sun set and the stars came out. What little of the city that remained connected to the power grid illuminated the ground in sections like Christmas lights. The formerly 600-meter-tall building cracked one final time, fell off Chee's cock, and crumpled on the ground below in a heap of concrete and steel.

Chee yawned, flopped down on his back--another section of the city collapsed and went dark--and looked up at the sky, then around to the landscape. There were no man-made structures left to compare himself to, only the rolling hills and the mountains just beyond them. He must have been at least 2500 meters tall, and hoped that by morning, he'd be even more massive.

He purred in satisfaction, tucked his arms behind his head, and drifted to sleep.


_Not all had fled the city. Some had hidden in the outskirts where the buildings thinned and that the cheetah seemed uninterested in. But they were interested in him--very interested.

There was a discussion about what to do and how to do it. There was alcohol involved. Climbing gear was packed, the group crammed themselves into a bus, and they headed for the snoozing giant. The closer they grew, the more a scent filled the air--the musky scent of someone who'd had a wholly satisfying day. It grew stronger, until when they were unloading near the cheetah's hip, the smell permeated the air.

There was more alcohol involved. It was 11pm, and if they wanted to reach the cheetah's summit before daylight, they'd have to climb quick. They took out their supplies and started off, free climbing through the cheetah's fur. He continued to grow beneath them, extending their climb by meters at a time. His musk thickened as the group made progress up the enormous body until they'd climbed his thigh and were able to take a breather on the top of his hip._

A few dozen meters away was the source of the scent--the cheetah's cock and balls. There was more alcohol still, and the drunken, yipping people waded through the giant's fur and up to his soft cock, where the musk was miasmic. They played on his balls, rolling in the plush fur there, and a handful of adventurers marveled at the gigantic cock itself. One drunk vixen licked the side of the cheetah's cock and a drunk feline climbed onto the cock itself, using the smaller keratinous barbs on the head as climbing anchors. Once she was halfway up the cock, she called down at her group. Half of them abandoned their play on the cheetah's balls, rushed to his cock, and began their own climb.


Chee shifted in his sleep. He was vaguely aware of a tickle on his cock and balls, but not enough of one that warranted moving his arms out of their comfortable position to scratch. He shifted his legs and fell asleep again.


The giant beneath them quaked and the group clung to him for dear life. When he shifted, he went through a growth spurt that launched his cock several meters longer and jostled the furs pressed against him. Once he settled down, they grew bolder. One climbed to the very tip of Chee's stiffening cock, where the smallest bit of precum had begun to collect. She lapped at it and a few friends came over to sample the macro nectar--a treat rarer than a unicorn.

The others rubbed against his cock while some continued play on the giant's musky balls.


That tickle on his cock and balls grew stronger. Chee rustled in his sleep and untucked one of his arms from behind his head. Unconsciously, he rubbed his hand over his cock. The tickle was... pleasant. Chee was suspended on the border between sleep and wakefulness, experiencing pleasure without knowing exactly where it came from.


_They scrambled away from the giant's hand, which came down and closed around the base of his cock. Like slow motion to them, the giant dragged his hand up from the base of his cock and those clinging to him panicked. Several more scaled the barbs to the tip of his cock, slipping on precum, and several jumped onto the cheetah's hand when it approached to avoid being crushed under his strokes.

They'd thought the musk couldn't get stronger, but it did. It was a fog that surrounded them, further clouding their alcohol-dulled minds. Those on his hand clung there, bathed in gusts from the cheetah's movement with each stroke. The vixen near the tip of the giant's cock fell victim to the scent and ground herself against one of the barbs beneath her. She couldn't help but think if she'd arrived during the giant's early growth, she might have been able to fuck herself on one of those barbs._


On the edge of wakefulness--and with his own added, slow stimulation--Chee became more sensitive. He became more aware of the tickle on his balls that increased desire in his cock.


The people on the cheetah's soft ball fur waded through it like warm snow, overwhelmed by the increasing musk. All those who had climbed the living mountain were hardly aware that he was shifting until they were thrown off balance onto either their stomachs or rears. Those who had enough presence of mind to see the sunrise and understand that both the light and the cheetah's self-stimulation would wake him fled through the fur and headed for the climbing ropes they'd secured around the bases of some of the thicker strands.

Some made it down. Most were too slow, and once the cheetah sat up, the motion dragged their climbing ropes too high off the ground to make them useful.


Chee dragged himself into a sitting position and yawned. It didn't take more than a second for him to realize that he was hard and that his hand was wrapped around his cock, but it took him a few more seconds to squint and discover that the tickle on his balls--and the lingering one at the head of his cock--were a group of people who had managed to clamber onto him in the night. Beside him, at ground level, a bus that zoomed away from him as quickly as it could; from his perspective it was a crawl.

How large was he now?


The giant stood and the few furs on his hard cock slipped off. They scrambled for purchase and managed to grapple the hairs beneath his cock enough to avoid falling. They looked down past the swell of the cheetah's balls and to the ground kilometers below.


He was gigantic. Chee looked into the distance, where he could see the curvature of the earth, and tried to measure his height in relation to the surrounding topography. The nearest mountain--dozens of kilometers away, but several steps proportionally--was three kilometers tall, and he was over thrice its height--taller than Mount Everest. His cock throbbed and he felt another slow stretch of growth pulse throughout his body. The city beneath him, crushed to nothing, was exactly that--nothing. It had no more to offer him, but the mountains so close did.

Chee headed for it. His steps parted forests, bulldozing the trees in his path and flattening them. He stepped on rolling hills like stepping stones on a garden path and tread through shallow lakes--puddles smaller than his foot. The rivers were no larger to him than trails of water running away from a car wash.

Chee stopped in front of the mountain, cock throbbing, and stared down at its snow-capped peak. He'd never played with ice before, but he was curious.


The climbers clung to the giant's musky fur for dear life as he traveled kilometers at a time with just a few steps. The cheetah stopped before a nearby mountain and the climbers in his fur might have frozen were it not for his heat.


Chee kneeled and tentatively rested the underside of his cockhead on the mountain's peak. An avalanche of snow tumbled down, annihilating the forest on its face. The heat radiating from Chee's cock melted the snow beneath it and streams of water flooded down, carrying with it chunks of rock and landscape dislodged by the previous avalanche.

It wasn't icy like he'd expected. The massive amounts of heat he put off made the mountain peak pleasantly chilly--enough to tingle his cock before he pulled it off.

On the mountain peak was a crater where his cockhead had been. Chee thrust his cock along the trench; his balls rested against the mountainside and another tickle drew his attention to that area.


The people tangled in the cheetah's fur deeply enough to survive the trip dismounted his balls and took their chances on the mountain, surviving the altitude only from the giant's heat and slipping through slush on the way down.


The people were specks on the snowy surface, which melted more and more by the moment as Chee's heat permeated the surface.

Skyscrapers were excellent to rut against, but not only had he outgrown them, but the pliability of the soil level on the landscape was satisfying in a way concrete wasn't.

Chee continued to thrust his cock along the mountain and purred. The slippery mountain against him was something like a tongue--if a tongue could apply much more pressure and if it could cling to the underside of his cock even once he'd pulled off. He ground against the crumbling mountain, eventually leaning forward on his hands and knees to continue to move against its dissolving height. With a final thrust, his cockhead sank into the mountain itself and he came into it with a trembling mewl.

He'd hardly recovered from the shock of pleasure when, with another hard throb, his body grew again, cracking some of the earth beneath him. His cock stiffened again and he pulled out of the mountain and rose up onto his knees. With a stroke, he wiped the residue from the topography off and turned to the landscape again. Clouds shrouded his vision and Chee blew on them, breath dispelling them instantly. Directly in front of him were more mountains, in their valleys expanses of forest and plains. One bit stood out to him--a valley narrow enough to sandwich his cock in.

Chee made toward it, leveling more and more forest and crunching short mountains beneath his feet. Once at the valley, he took to his knees again and shoved his cock between the mountains that created it. They closed around the sides of his cock and the valley below pressed against his underside, giving him a three-way pleasure he hadn't experienced since he'd fucked the city's prized skyscraper.

The forest bent inward when Chee thrust into the valley; the canopy tickled the edges of his cock while he fucked it until climax crept up on him again. His musk was intense--so strong that Chee could smell it in the air even with his advanced height. With a hard jerk of his hips, he flooded the valley with a river of cum that rushed through it, washing away what little vegetation had escaped his cock's path.

He was still hard. Chee rubbed against the mountains that led into the valley until they crumbled beneath him and then moved to the next highest peak. His thudded the underside of his cock against it and ground his cock and balls on its peak and slope until it, too, crumbled.

His body throbbed again. The next tallest mountain was 2.8 kilometers tall. Chee was 11 kilometers high beside it, and his body pulsed in a slow motion along with his heartbeat. Rather than rocketing his growth, he grew only a few meters with every beat. Once his growth stopped, Chee was sure his cock would soften again.

He looked over the landscape--through more clouds and into the distance, where mountains gave way to hills and the landscape flattened only to rise again.

Chee stopped beside the mountain, took to his knees, and wrapped his hands around its base. He jerked and it cracked off its base, sending an avalanche of snow and rock down its slopes. Chee rubbed the uprooted mountain against the underside of his cock while he lay his balls on the base which rose a few hundred meters from the ground. While he thrust and dragged the mountain over his cock, he ground his balls against its truncated base. Leaning over a bit farther, he was able to rest his bristled cockhead against the peak of another mountain, wrapping it in the mountain's slope while he crushed the mountain in hand against the underside of his cock.

He panted. The pleasure wound tight in him, and with a final, hard throb that jolted pleasure through his every nerve, Chee came against the mountains, grinding the base beneath his balls into nothingness and smashing the one in his hand against his cock. Cum spurted over the peak his cockhead rested against, sending a different kind of avalanche down its slopes that drowned a village near its base.

With a sigh, Chee righted himself, fell onto his rear, crushing a mountain beneath his balls, and let out a long, pleasured sigh tinged with a purr. With half-shut eyes, he surveyed the leveled mountains and the flattened city in the distance. Had he not been exhausted by his last stretch of growth--and multiple orgasms--he might have crossed the border into another country and shared with them his massive size... but that was for another day. Now, a nap sounded good.

Chee lay back, crumpling several more mountains beneath his weight, closed his eyes, and drifted to sleep under the afternoon sun.
