Chapter 1 by Jacksmith

It was supposed to be an average gig. Research facility, first floor: in and out. The kind of thing I can do in my sleep. Plus, the money was better than usual.

I cleared the guards and the laser tripwires in record time. My standard. Skeptics usually take one look and disregard me before they’ve seen me in action. They laugh sometimes and ask how someone as tall and curvy as me, with pearl skin and ginger-fire for hair that stands out in the dark, could make an effective stealth operative. Those are the people I haven’t stolen from yet.

Once I was in the lab, though, I could tell something was wrong. Things weren’t where they were supposed to be, and it was screwing with my timeline. An alarm went off and the guards came rushing in. They sealed the exits and told me to get down on the ground, and even before I could move, I heard them clicking off the safeties. That’s when I knew someone either gave me a bad tip or just wanted to set me up.

I got down like they said. I could hear my heart in ears. This was a first for me, since you don’t really stay in this business if you get caught, but I’ve always got a trick up my sleeve. When the first guy came near me, I’d already broken his wrist before he could even make a sound. I had his gun then, which helped even things a little, but once they opened fire on the whole lab, I saw my chances running out. Beakers and containment units burst and sprayed all around me. Tanks split open and started seeping chemicals. I took one guy down, just before I felt the sting of a bullet in my side.

I went down, but just then the gunfire stopped. Everyone piled back out the only door left and sealed it behind them. Suddenly I was stuck in a closed laboratory filling up with toxic fumes. I did my best to filter the air, but I could feel it entering my lungs, and worse, there were no masks left out in the lab.

I was just running through my own last rites when I realized the pain in my side was gone. Strange, I thought, since I was shot and all. Maybe the chemicals were giving me a high right before the poison kicked in. Then that numbness turned to tingling, starting from the wound and spreading across my whole leather-clad body, from the top of my head to the tips of my toes, then back again. I stood up, feeling all right and more than a little shocked, but nothing could’ve prepared me for what came next.

My clothes were getting tighter, and fast. I could feel the seams straining against my hips. The fabric stretched over my breasts. Each stitch was coming undone at once. Threads popped around every curve of my body. Even my boots were tearing over my ankles. I admit I’ve got long feet, but they weren’t big enough to tear through shoes, at least not until now. By the time I figured out what was happening, it was too late to try taking off my clothes because they were so taut to my skin. Instead, I grabbed hold of the nearest lab table to ride it out. I felt my clothes shaving into patchwork shreds, starting around my shoulders and waist, but spreading quickly. In no time, I was standing there in the tatters of my uniform, and only when I let go of the table again did I notice it was over a foot lower than it was when I grabbed on.

I wasn’t hallucinating, and my clothes weren’t shrinking. My body was expanding. Not getting chunkier or longer, but swelling outward in perfect proportion. It seemed impossible, but it was happening anyway. I was growing.

I didn’t know what to do, except think of ways to get out before I became too big for the room. I tried the exits and air shafts around the perimeter, but all of them were sealed tight. Still, my body kept growing, becoming bigger and taller all the time. In less than two minutes, I’d bypassed seven feet, and I didn’t think it was going to stop. Soon, I bumped my head on the ceiling. Even after I sunk to my knees, it didn’t make much difference. My body was eating up the space in the lab faster than I could adapt, and I had nowhere else to go. The rest of my catsuit fell off in ribbons, and finally my bra and panties ripped away too.

I felt exposed, but only for a second. I had much bigger problems. With the ceiling approaching over my head, I braced myself for impact. I pressed my hands flat against the ground, flexed my soles, closed my eyes, and…

In the span of a second, my body redoubled and quadrupled the speed of my growth. When I arched up to meet the ceiling, my head passed right through it as easily as aluminum foil. There was no pain, only surprise as I watched the floor above buckling from the pressure of my body breaking in. Dollhouse-sized tables and lab equipment scattered. When I reared to my full height at last, my shoulders and the rest of my torso crashed through the next floor above. And then I felt something else. Something I would never have expected to feel after I’d been caught, shot, and exposed to a chemical disaster.

A little drop of bliss, starting at my core and working its way through. Goosebumps prickled my skin and warmth stirred under the surface. Soon it blossomed to full-on euphoria. I was taken aback, even more than I already was, just as my head touched the third floor and stretched the metal like tissue. My arms rose through the collapsing wreckage and I touched my fingers to my cheeks, just to check if I was dreaming. But I wasn’t.

My hair came undone in the back, and suddenly fiery strands were hanging in my eyeline. I brushed them aside just as I hit the fourth floor. Here, security gathered again in the debris, but when they opened fire, it sounded more like singing cicadas, and it hurt me even less. I laughed the kind of booming laugh that could echo across a whole countryside. Most of the men doubled over just to cover their ears. I should’ve felt afraid. I should’ve felt ashamed that everyone would be able to see me naked, and alarmed that nothing could ever be the same again. But I didn’t feel any of those things. When I looked down at myself, I saw only a form to be admired and respected, even worshiped in time.

I felt good. Powerful. But I wanted more.

More to come soon.
Chapter 2 by Jacksmith

“Oh my God, what a rush. You can’t imagine what this feels like. Thank you, boys, for your help in making this happen.”

Before they could pick their tiny guns back up, I swatted them aside with my gargantuan fingers and blew them over with a gentle gust of my breath.

By the time I entered the fifth floor, I could feel rubble below crumbling as soon as it touched my body. Fires were starting, the flames lapping at my skin, but they didn’t do much more than make me even more relaxed. Plaster and steel cracked wherever I laid my fist or even turned my head. I didn’t have to move to wreck everything around me since I was growing so fast, but of course I did, because I couldn’t wait to see what would happen next. When I lifted my foot for the first time and set it down somewhere else in the collapsing lab, I felt a generator squashing under my heel like a soda can. When I pressed down and rolled it along my arch, it exploded into a chemical fireball, but only tickled my sole. I couldn’t help but laugh, and like a thunderclap, my voice easily overpowered the downfall of an entire laboratory complex.

It was wonderful.

The building was coming apart at the foundations just to fit around my growing body. I heard the stone rumbling below my bare feet, which now filled in most of the laboratory I was trapped inside not a minute ago. Girders crashed all around, and walls came tumbling over, but all it took was a wave of my hand or even a flick of my finger to clear it away. Windows blasted outward when I felt my ass swelling against the tiny pocketed panes. My body ascended fast through the sixth, seventh, and eighth floors. Each time I burst through another story, everything broke even easier, until I barely noticed it at all. My hips reached the east and west walls of the building, threatening to tear through it just like I’d outgrown my clothes. Most of the facility was a husk now, and what was left standing was only intact because I could hold it up.

“Everyone better watch out. I’m on my way now,” I announced, so anyone in a three-mile range could hear. I crossed my arms and inhaled slowly, just as the crown of my head tested the paper-thin brick of the roof. “I’d tell you all to get ready, but I don’t think anything could ever really prepare you for me.”

At once, I spread my arms wide and stretched my legs out. What remained of the building turned to splinters, most of it on me. I wiped away what I could, and for the first time had a real sense of just how big I’d gotten. I knew it had to be pretty damn huge as I counted the floors of the lab cracking one at a time, but only when I was standing almost as tall as the cityscape beyond did it really sink in how enormous I’d become, and I was only growing bigger all the time.

“Oh, this is going to be fun, isn’t it?” I said to myself, and laughed again. Just hearing the sound of my own voice and booming laughter span across the land filled me with delight. What’s more, that sense of exhilaration swimming within had made its way between my legs, and I wasn’t merely enjoying myself anymore. In fact, it went beyond plain old horniness. None of my random lays ever felt anywhere near this good. Hell, I’d never made myself feel this good. I staggered for a second, catching myself against a satellite tower beside the trashed laboratory. It curved and snapped off in my hand like a twig, but by then I’d adjusted, and knew I had to see this through. When I lifted my foot from where it landed, a few cars flat as flies peeled away, imprinted with the shape of my wrinkled sole.

I made my way along the winding road, through the shrub-height trees and toward the downtown area, which still twinkled against the black night sky. Every time I took a step, my foot sunk into the ground like beach sand and left behind a long swimming pool-sized crater. After I got used to this, I could move faster, crossing whole blocks in one stride. Only once I was halfway to the city did I notice that cars were still humming along the road, and a lot of them were now crushed flat into my footprints. There wasn’t really a point to watching my steps at this point, I thought, so I kept right on moving. This time I tried focusing on the sensation of every toy vehicle smashing to smithereens under my growing feet, slowly screeching and popping to scrap from the weight of my soles, which I found only enhanced the experience. I wanted to feel and savor everything now.

And God, did I ever. Even though I was eager to arrive in town and let the people see me outgrow the buildings, I couldn’t help but take a detour, wandering off the country road and down the hill toward a little suburb still with a few lights switched on in the windows to guide me. Yes, it would be fun to show off my progress in the city, but the lure of this side-trip was too great, just imagining half the neighborhood already asleep in their beds, only to awaken when their rooms shuddered from repeating aftershocks. Steps away now from reaching the closest backyard, already just barely large enough for me to set both feet inside without knocking over fences, I could picture the people sleepily drawing back the curtains to see what the fuss was about, expecting other neighbors concerned about the earthquake, but instead finding little ol’ me trespassing in whatever was left of their lawn after I finished trampling it. But, on the plus side for them, they’d come out of this with a free swimming pool pit wherever my foot landed. They really should’ve all thanked me.

Choosing my target, I wedged both feet into the fenced-in lot while I could still fit, then lifted one leg high over the roof before dropping my heel. I barely even had to touch the chimney to make the structure implode. Since I’d already bent and broken straight through the skeleton of the laboratory easier than a cheap Halloween costume, I guess I shouldn’t have been surprised at how effortless it was, but I was still getting used to the many delights of my new size, and every act was just as affecting as the first. A whole staircase cracked under my toes; appliances, furniture, and probably-residents were all pulverized to powder under the curve of my arch.

A fresh burst of the same thrill shot through me as my foot passed clean through the house, rafters and walls leaning in around my leg as I let my sole sink fully through the sagging floors, crushing them to sawdust all the way down to the basement. When I withdrew my foot, wriggling my toes and letting debris tumble like snow through the sensitive crevices, the crackling afterglow was even better. Now that most of the house had been redesigned with a massive blown-out void in the exact shape of my growing foot, the place was teetering on collapse, and all it took was a nudge from my big toe to finish leveling it.

“Yeah, okay,” I murmured in acknowledgement of the ecstasy burgeoning inside. “Maybe just one more.”


Chapter 3 by Jacksmith

Naturally, the next-door neighbor’s house seemed a bit undersized compared to the last, but that was only because I had swelled higher, and this time I just had to make contact once to literally bring down the house. Rather than hammer down my whole meaty sole this time, I took a gentler approach, pointing my toes like a ballerina and dipping my dangled foot into the roof. Everything still collapsed around my foot, with my ankle the only thing maintaining any kind of structure for the crumbling place, as though it was all made of popsicle sticks on the verge of ruin. As soon as I pulled my foot out again, it disintegrated to junk. Satisfied now, I hiked back up the shallower hill, resuming my stroll on the road and letting cars splat like beetles under my heels.

By the time I reached the city, buildings which looked double my height from the lab site now just barely reached above the top of my head, but I was gaining on them fast. I could hardly keep up with the rate of my growth. All I knew was that my size was increasing faster all the time. It was impossible to estimate, except to acknowledge that I now had to be the largest living thing on planet Earth. And I was just getting started.

“Good evening, everyone!” I bellowed. I could practically see the buildings wobble just from the force of my voice, and I hadn’t even laid a finger on them yet. Where my feet came to rest in the street far below, I created a literal traffic jam. Most of the people abandoned their cars, some doing the smart thing and running away as fast as their little legs could carry them, but most of them stopped in their tracks just to look up at me.

I’ve made a career out of never being noticed, yet as I stood above a thousand terrified onlookers, fully exposed, my long legs and shimmering red hair bathed in urban starlight, I realized I’d been missing out. This was the perfect score I’d been waiting for my whole life.

I bent over and reached for a city bus gridlocked in the street. Wrapping my fingers around the sides rekindled the surge of pleasure, and out of instinct, I squeezed. Hard. It only took an instant for the whole machine to crumple against my palm. When I opened my fist, I could see the geometry of my powerful fingers carved into the metal, and I bounced the hunk of metal in my hand like a softball. Just in case my entrance to downtown wasn’t big enough, I cocked my arm and hurled the bus down the street. It rolled and crashed through cars and citizens bowling pin-style, before it came to a stop at the base of a skyscraper.

Tramping down the packed street, I kicked aside cars with my toes and trampled crowds under my heels, but my gaze was locked to the wall of windows making up the tower. The surface was so smooth and mirror-clear, I could see my whole body in the frames. Even better, I could make out my colossal form continuing to expand, outgrowing the reflection, the cataracts of red hair falling over my moonlit breasts. I’d passed up the office buildings on both sides, and soon the street wouldn’t be wide enough to contain me, either. It was all so amazing, and I was tempted then and there to thrust my fingers between my legs and encourage the temptation roiling inside, but I willed myself to wait. There was still so much fun to be had.

By now, the people below had gotten the idea I wasn’t there to be friends. They ran in crazed pandemonium, which didn’t bother me. I got to enjoy the individual tingle of every puny body crushed under my big soles, but I didn’t care about them. All I wanted now was to prove my growing power, to myself and everyone who remained. I wrapped my hands around the sides of the nearest apartment complex and started to rock it side to side. It came loose even easier than I imagined, and with just one hand, I shoved the entire building onto its side. Dust billowed to every direction in a fog, but the gale wind of my rising foot quickly cleared it away, just before it crashed through the downed building like styrofoam. The larger I grew, the finer the texture of the destruction became on the soft undersides of my feet, from shattering glass and stone, to something more like the crunch of a stale cheerio under my big toe.

My hips were starting to outgrow the distance across the street, much like what happened just before I tore through my clothes. I relished the feeling, swinging my arms wide and shaving the top floors off every building packed into the block. When I let my butt swing from side to side, knocking the brickwork and caving it in, I could feel the walls straining to hold me. I called out to everyone below:

“Oh, if only all of you down there knew. If only you could feel what I’m feeling now, I’m sure you’d understand why I’m doing this. It’s intoxicating. Better than any drug, better than sex, better than anything. And the only way to keep it going is to show you what I’m capable of. So that’s what I’m doing. I hope you’re all watching, and I hope you’re all enjoying it even a fraction as much as I am.”

I was studying my reflection in the skyscraper again, wondering how long it would be before I dwarfed the tower as well, when I heard the buzz of insects by my ear. Army helicopters strafing around my head. Several went down when I swatted too fast for them to dodge, but before I could snatch the final two, they launched their payload. Two bombs plummeted, each one landing at the peak of my breasts. Though I noticed the explosions for sure, it didn’t come to much more than the feeling of a nipple tweak, which only heightened things for me. But that wasn’t the only thing.

A sensation, like what I’d experienced back in the lab, electrified my body. I halted in place so fast my foot nudged right through another building, bringing it crashing down with just the tips of my toes burrowed in the foundations. My lips parted and a gasp escaped that resonated across the wreckage. Like last time, I pressed my fist through the skyscraper for support, but once the effect of the bombs leveled off, I was on my way up again, and the tumbling citadel was left at my knees. I was soaring, yet my feet never left the ground. While the night sky approached above and invited me closer, I felt the city vanishing into the river creases of my sole, forests razed under the round of my heels, and civilization itself oozing up in the tender crevices between my long toes.

The next time I took a step, I found I could cover a mile at a time. Forget cities. I could crush entire counties in one go. Once the bombs wore off, I wasn’t growing as fast, but I was still getting bigger by the second. Every muscle I moved resulted in another surge of pleasure through my extremities. So I took a stroll. Hills and low mountains became like dunes and eventually anthills I only had to reach a little farther to clear. Suburbs turned to dust under my feet. New cityscapes were mashed into paste just by planting both soles side-by-side and shuffling through the swath of ankle-high buildings, which came down easier now than cobwebs. Every town I squashed, every road I pancaked, and every speck-sized human I stamped deep into the earth brought me the kind of elation I never dreamed I’d experience in this life. Reeling, power-hungry, desperate for more, I alternated filling the night with my booming laughter and haunting moans the higher I rose.


Chapter 4 by Jacksmith

Looking to the sky, it seemed so little separated me from the heavens now. As though if I only grew a bit bigger, I could reach up and grab handfuls of clouds, maybe even stars. The thought was a bit preposterous, but then again, even an hour ago, I’d have said the same thing about the concept of me growing into a naked colossus, my every delicate step demolishing all life and manmade accomplishment under my weighty sole, cutting new craters into ancient rock easily as wet clay and sending shockwaves to both planetary poles from the moment my toes hit the dirt. Yet here I was, bigger than I imagined any living thing could ever be, and only growing bigger. So, what was any impossibility now in the face of my miracle of a body? I spread my arms overhead, while huge cities continued dwindling lower next to and especially under my constantly swelling bare feet. I couldn’t grab the sky quite yet and bring it crashing down, but I had to be close. Just a little taller, and all would be mine.

My tour of the world continued with no particular direction except where my feet guided me. Eventually I stumbled on a suburb at the edge of the mountain range. While the structures below me were still large enough to be noticed one at a time, which probably wouldn’t last much longer before I outgrew even these specific sensations, I made a point of flexing my toes to a full spread, then proceeded to rake the tips through winding streets of quaint little family homes. Speck-sized cottages were collected into the valley between my digits, but most turned to soot the moment the bulbs of my toes struck them like battering rams. When I arrived in this adorable country town, it took a sweep of my leg to clear the landscape of houses, but by the time I was ready to move on, I didn’t have to do much more than smear my foot to the side to obliterate the leftovers.

Time passed, and I kept right on growing. So too did my arousal expand, almost as fast as my size, and I had to fight the urge to help myself along. Not yet. There was still much to see. In a matter of earth-shaking steps, I’d transported myself somewhere entirely new on the opposite coast. Everywhere on this puny globe seemed within my grasp now, even though it still outsized me, at least for the time being.

As I trekked over new mountains, summiting them all with a stride that now covered multiple miles, I hadn’t fully grasped just how big I’d gotten until I discovered a lovely point of reference. Far below, past the forests and hills, appeared an impressive metropolitan sprawl, the largest city I’d yet encountered, so spacious and populated with hundreds of skyscrapers like silver needles, the place was almost bigger than my foot. Almost. Comparing them next to one another, I could see it wouldn’t take much more of a growth spurt to give me the advantage, but I didn’t think I needed to wait to become any bigger before taking this thoroughly gratifying step. Arms at my sides for balance, I gracefully peeled my sole out of the ravaged terrain and held it aloft above the twinkling span of civilization.

For a moment I let my foot hover over them all, surely eclipsing their night sky view entirely with the flesh of my long sole, and then I gradually lowered to stand on this immaculate urban marvel all at once. Slow as I could move without losing balance, leagues at a time, my sole descended, until I felt the highest lightning rods and skyscraper peaks fracturing against the unstoppable force of my foot’s underside, the sensations so slight they may as well have been insect legs grazing my skin. The rest of it went down just as easily.

Cinderella herself couldn’t have hoped for a more perfect fit; from toe to heel, it was like this city was made for me to smash underfoot, though it wasn’t long before I’d grown too large to use the municipal map like a creek stepping stone, the last vestiges of the suburban outskirts vanishing under my expanding sole. The place crunched uniformly as a fallen leaf, contouring itself to the slope of my arch. I could feel my heel and the ball of my foot burrowing in the deepest craters, but everything under me, from the tallest high-rise to the squattest citizen, was still squashed down from three into two dimensions. The Earth’s bedrock crust even bowed to the force of my growing body now, denting like the cracked surface of a frozen pond. I knelt closer to the ground, witnessing my foot literally outgrowing the remnants of the pitiful city. My instep, heel, and toes seemed to bulldoze right through the muddy refuse of fallen buildings and twisted streets without having to even move a muscle, since my evolving body needed no extra help. Patches of skyscraper districts which once looked like tiny metallic blades of grass now became more like the scant shapes of computer chips relative to my immense scale, the grand architecture too small for me to distinguish with anything other than direct contact.

Relishing every minute sensation, I rolled my foot to and fro, grating the city into a fine particulate mess, thousands of tons of metal and glass from the expansive downtown effectively turned to glitter now that decorated the crevices between my eager, ever-bigger toes. At this point, I received especially potent confirmation of that myth about the semi-erogenous zones in those doughy spaces, while intermingled buildings, cars, and humanity again gushed through the fleshy openings astride my dexterous toes, only to become ensnared when I clamped my digits together again and pressurized them into pulp.

Though I knew it was impossible, I swore then that I could feel thousands of tiny bodies squeezed into the deep ravines of my sole-wrinkles, infinitesimal hands desperately and fruitlessly pushing up against me in pleading hope of mercy, even when a hundred of them banded together wouldn’t have a hope of resisting a single skin cell of my foot’s underbelly. I didn’t even have to try, though I did anyway, loving each instant of the increasing pleasure. What must it be like, I wondered, to stand in the middle of ashes and barren wasteland where once stood a city, to look up and see nothing but spiraling toeprints, oily textures, and a sky-sized tapestry of peachy sole furrows coming down upon you? The thought only spurred me on, and I pressed down harder than ever, igniting the nerve endings in my brain and cataloguing each microscopic poke I felt dotted beneath my arch. I wanted to thank each and every person down there for their part in firing me up, but I decided the godlike echoes of my sighs would have to be enough. Every illusionary tickle of resistance penetrated my foot, and I couldn’t help but quake where I stood, still loudly thundering my joy across the land while almost wailing with animal lust and glowering down at all of those unfortunate, very-useful souls now painted across my foot.

With my head somewhere in the clouds, long after I’d ceased thinking of the tiny world below and only of my next growth spurt, a nuclear power plant was mashed under my pinky toe. I assume that’s what it was, because only something with that much energy could explain the ascent that followed. I didn’t just grow. I skyrocketed. The faster I outgrew the cities, the townships, and even the land and sea themselves, I knew I was getting close now. My body ached for release just as much as it craved growing again.
I didn’t think anything of it when I felt the curve of the Earth deepening against my soles. The cosmos spanned before me, but before I could even consider reaching out to grab them, I had to finish what I’d started. I wrapped my legs all the way around the planet and clutched it to my body to keep it from floating away, my hand on my hip, my pussy grinding softly on this vulnerable little world. The greatest climax of my life was approaching even faster than I was growing, and only just ahead of Earth’s last gasp. When I came, I do believe any life out in the void heard me, too. Certainly the world felt it just before it cracked between my feet and broke into dust, but I’d already forgotten about them.

All that was left now was the pursuit of becoming bigger and bigger, higher and higher, until there was nowhere left for me to grow.
