The three-story giantess laid the Kraken before her, tilting its tiny tip down towards her entrance. The peak of the tentacle looked downright puny at just one inch thick, but it was its foot-wide base that Viv was interested in. This dildo was going to make her fucking gargantuan.

Her pussy loved the thought of it, guzzling out ounces of cum a second now. Some of it dribbled into her asshole, still gaping in the cyclops’s wake, but it mostly trickled down into a puddle that now spread far beyond her back, easily taking up most of the floor space. The smell of her sex, so thick in the backroom, wafted out to the front of the shop; it could probably be picked up outside the storefront.

Viv brushed the tip of the tentacle along her labia, closing her eyes as she descended into a lurid pirate fantasy. It started out innocently enough, with her chained to her swashbuckling partner in crime (god, Jake would look good in an eyepatch, she thought) as they awaited execution in some ship’s damp cellar. Then some foreign tendril would slither in through a loose plank and penetrate her; her handsome companion would rush to save her, but she would simply kiss him, aroused by this wonderful new feeling inside of her. And as the giant octopus slid further in, she’d grow with it, smashing cabins and bursting through the deck of the ship as she kept her tiny buccaneer safe against the cushions of her lips. And yet even as she outgrew the ship itself, sending screaming crewmen plunging into the waters below, the tentacle inside her seemed to swell more and more, surging—

Wait. The tentacle was feeling bigger.

Viv opened her eyes to find herself grinding against the Kraken, six times the size it had just been. No— she had shrunk! The spell had made her smaller to fit the dildo since she had only been pleasuring herself with the tip.

Pushing both hands against the four-foot cock’s underside, she found she couldn’t even lift it now. Viv huffed. She was as small as she had been when she started, maybe even smaller. She wouldn’t have to start the whole process over again, right?

No. She had a boy to grow for, and she needed him badly.

Arching her hips up to slide the tip inside of her, Viv took a deep breath and, clenching her teeth, thrust herself onto the beast. Oh god, maybe the spell just wore off, she realized a second too late.

But luck was in her favor, and every part of her shot outward to accommodate the nine inches of cock she had just swallowed. She bucked her hips again. Another inch of cock, another foot of height. Two more inches, two more feet. Her swelling hips touched the ground. Reaching forward, the twelve-foot woman was able to grab onto the base of the Kraken now, and she pulled herself onto it with all her might.

“FFFFFFUHHHCCKKK,” Viv cried as the giant tentacle pushed up through her depths. Her back slammed into one wall as her feet hit another. 16 feet, 20 feet, 24 feet. She slid down onto her back like before, but her head and toes both raced towards the ceiling even as she tried to keep both as low as possible. A loose hand knocked over two filing cabinets — sending papers floating towards the ground, where they drowned in a growing pool of cum.

The room was dangerously tight now, and as the concrete walls held firm, they seemed as if they might crumple the swelling giantess. Viv clenched her teeth as her knees folded up against her chest. Her lust for growth was going to kill her.

But growth was the solution, too. With a deep breath, she stuffed more of the Kraken inside of her.

In the front room, two giant feet burst through like the Kool-Aid Man, spilling debris onto the display racks below. Calves and thighs followed, kicking out and crushing whatever poor display tables they landed on.

Stretching out, Viv bulldozed the wall’s lower half with her butt so she could lay flat. She had become an amateur renovator of sorts, converting two rooms into one and pushing aside everything to make room for the store’s growing centerpiece.

As she lovingly shoved the Kraken further inside her, her soles shot out a few more feet, racing towards the storefront. Forget the backroom; this building was about to have trouble containing this much woman.

And the woman in question fucking loved it. Viv used her free hand to knock clear the rest of the dividing wall, giving her a full view of her new domain. She slammed a vengeful leg against the counter she had spent so many shifts at, sending glass exploding everywhere. That type of thing didn’t hurt her, not when she had skin so thick you’d need a butcher’s knife to pierce it.

With a final thrust, Viv’s pussy ate up the last of the sea monster, making her buck her hips in ecstasy — and then send them slamming to the ground again, causing dildos everywhere to fall off their shelves. With a moan, she laid her giant head down onto the backroom floor, her hair soaking in her own cum. Candi’s Shoppe was roughly the size of a twin mattress to her, with the front section encompassing everything from her nipples on down. The ceiling wouldn’t even reach her knees if she was standing, and she figured that must have made her about 40 feet tall.

Touching the store’s front wall with her right foot, Viv curiously traced her toes along display racks and posters, leaving a visible trail of destruction wherever they went. It felt like messing with a sequin pillow. Wrecking things was fun, though she supposed at her size it was just a side-effect of existing.

Her foot landed on the five-foot phallic sculpture she had been cleaning earlier, back when she was just a hair taller than it. Her big toe stroked it lustily. Of course — the store’s biggest cock had been sitting in front of her all along. Unlike the Kraken, he was thick all the way through. Thick enough to bust her free from this pathetic coffin she was laying in. 

Removing the monstrous tentacle from her insides with a squick, Viv carefully slid the stone dildo towards her with her foot.

Using both hands to get a hold of the heavy sculpture’s girth, she pulled it up to her lips — her actual lips. She had to see this colossus up close; any scratches caused by her reckless growth might upset her pussy. Her foot-wide tongue glossed its polished surface, not even coming close to covering its impressive girth. Going down the sculpture, she rubbed her cute little nose against a (literally) rock-hard shaft. Not a scrape to be found. He was perfect.

She slid the sculpture back down across her stomach, its form feeling like a heavy dumbbell even against her 13-ton body. Cum was now trickling from her pussy with ludicrous intensity, and had begun to trickle out past the front doors — giving the outside world the first visible evidence of the giantess, though there would soon be a lot more where that came from.

Careful not to dent the sculpture (indeed, it was now the only item in the shop to have gone unscathed), Viv guided it to the ground between her thighs and slid it towards her labia.

The first thing she felt was cold. Her body heat had turned the whole store into a sauna, but the sculpture was taking longer to adjust; relative to the silicone toys from before, it felt like an icicle against her folds. The second thing she felt was pain, as she had slid the column’s thick head a little too quickly through her entrance.

Both feelings were instantly subsumed by pleasure, however, and her pussy eagerly throbbed for more of the gigantic dong. She was thrusting it in and out now, feeding herself a few more inches with every push, and her body reacted accordingly. Those feet that she had stretched towards the front walls were now flatly pressed against it. She stuck a hand on her head to lessen the growing pressure of the back wall on her scalp.

Up until now, the giantess had managed to hide her growing body from Shelby Beach, despite easily being the Earth’s heaviest land animal. But some secrets are just too big to keep.

And so the elephant outgrew the room. Two soles taller than people exploded through the storefront, sending debris scattering across the street ahead. At the other end, Viv’s head broke through into the night sky, gasping as she finally received a breath of air not pungent with the scent of her own cum. She spread two titanic legs apart, busting down the side walls and sending the entire rooftop collapsing down onto her body. Her hand shielded her privates from the falling debris, and the giantess kept pumping herself full of stone cock, still growing six inches a second.

Sliding her other hand into the wreckage, she grabbed into the sculpture’s base with ten fingers and heaved her giant body onto it, shoving all of the five-foot cock into her tunnel. Her heels stretched past the sidewalk and onto the asphalt. She came gallons.

Viv let out a satisfied moan, making some nearby squirrels scatter. She sat up, disrupting the sea of structural damage that had formed on her lap, and stretched two massive arms high into the night sky.

No helicopters circled her head, and no news crews formed at her feet; it was past midnight on the far edge of town, and it was still likely no one had seen her at all. Far away from any streetlights, she was just a big dark blob against the night sky.

Even with her car-sized asscheeks on the ground, Viv was Shelby Beach’s tallest structure, and she watched as the sleepy town twinkled before her. She thought to check the time on her phone before realizing it, like the rest of her former life, was likely gone forever in the rubble around her hips. Even if she managed to dig it out, it would be the size of a fingernail, useless to a titaness like herself.

Titaness. Viv smiled. She had become Jake’s 50 Foot Woman. His cock was too big for her just years before, and now she had a pussy he could crawl into. Another moan escaped her lips at the thought of it, and a finger slid back into the debris to rub her clit.

She looked to the east side of town, imagining Jake asleep in his bed, deep into some giantess fantasy that was about to become very, very real.

No… he had to be at Lana’s. Stopping by the store earlier, she had said her parents were away for the week. That bitch would have dragged him back to that hideous McMansion of hers.

Looking towards the large house at the top of a distant hill, Viv scowled. The lights were still on. They were probably fucking at this very second.

The giantess stood up, brushing off insect-sized dildos that had stuck to her sweaty ass. When she ruled over Shelby Beach tomorrow, she didn’t plan on being entirely merciless. Those who kissed her enormous feet would be well-compensated. But heathens? They deserved special treatment — and the demoness who had ruined her life would be the first to stand trial.
