wow that was hard

Jaz was from Vault 78 and she was all alone now. Well, sort of alone. The others were still there, just…in a different way.

The vault door groaned. The oversized cog was rusty and flakes of red and orange fell as it moved. Unlike the other vaults, this vault door wasn’t just big, it was massive. From top to bottom it was nearly 100 feet tall and weighed metric tons. Despite this however, is was beginning to move.

Taking a deep breath, Jaz felt her legs getting tired. They were wobbly and the muscles in them were getting hot. Sweat was beginning to drench her blue jump suit with its iconic gold trim and numbers. Her cleavage was dripping, and she had already pulled the front zipper down, letting the bounty of her bosom pop out. Despite the suit’s synthetic weave that had been made specially for her vault, the material was beginning to strain. Her buttocks, having worked so hard to push, was ready to explode out!

Looking over her shoulder and down her backside, Jaz frowned as she squeezed one big butt cheek. It wasn’t just big and plump, but also shaped by muscle and power. But still, why did so many of them have to go there? Her butt seemed totally fine with this, being perky despite its mass it held itself up with a boastful pride that said that it was not at all ashamed.

With a sigh, Jaz turned back to the vault door and started to push on it once more. She was nearly as tall as the comically oversized cog, which was the intention of the people who designed the cog in the first place. In fact, everything about Jaz had been designed by those people from so long ago, from the amazingly stretchy material of her jump suit, the vault door that dwarfed all the other vaults, and…well her! All of her…all 90 feet of her.

Sitting down, Jaz leaned against the door. The entire contraption groaned against her weight and flakes of red and brown fell into her black hair. She blew some of it off her face and rolled her eyes. Why couldn’t the overseer had people grease this damn thing?

Vault 78 had been advertised as being the home of the future! A future that was destined to be washed over by the tides of atomic warfare. A home that would preserve the mankind of today, for the world of tomorrow. A shelter for the centuries of radioactive domination that would follow mankind’s hubris before the world finally became green once more.

Vault 78 had succeeded in this, and while the world wasn’t entirely green yet, the radiation was tolerable. And while not the genetic lineage of everyone who have moved into the vault was still around, there was still Jaz.

And Jaz, well she was all that mattered. It was Jaz who ultimately was the biproduct of Vault 78. For while other vaults were intended to be the incubators of mankind, others such as vault 78, were made just incase things were…well, a little more ‘out of hand’ and if the mankind needed a boost in order to survive. In fact, if everything went according to plan, then Jaz would help usher on a new order of mankind. Or would it be womankind?

Jaz wondered about this for a moment before shaking her head. “If I don’t get out of her, I’ll just end up as some oversized skeleton for someone to dig up.” With that she got up. If she didn’t get out of her, not only would she end up dead, but the fate of the other vault dwellers would have been for nothing! Jaz was fine with being what she was.

Vault 78, unlike the other vaults, was self-aware of its experiment and ultimate purpose. Most of the vault dwellers were scientists, many specializing in radioactive genetic manipulation. For decades that had worked to create the first ‘ever growing’ human being. A being that was capable of not only surviving and thriving in a nuclear wasteland, but also able to dominate the new, strange, and enlarged monsters that roamed the world.

Humanity was no longer at the top of the food chain. So, before humanity could take back its role as the most dominate species, humanity would need to once again conquer the food chain.

Jaz, being fortunate enough to have been born in a vault, was even more fortunate when the vault finally made the breath through, and like winning a lottery, she drew the stick to become the facilitator of the vault’s purpose.

Jaz became the growing giantess of vault 78.

It had been over a year since she was injected with the G-Strain. She could still remember that day so clearly. The Overseer had been the one to inject her with it. There were others there too. Coming up to the day of injection, many were worried that the Oversee would inject herself! She might have too had it not been for her fear of the mob. So, she injected the scrawny Jaz.

People were jealous of Jaz after that day. Walking the corridors that ringed around the unique steel beehive, she could feel them looking at her with envy. With every inch she grew they became more and more sullen, especially the women. Some of the men appeared to be the opposite.

Maybe it was just natural for the females of the vault to be jealous of her. The entire vault was now purposed to facilitate the needs of Jaz and her growing body. Shaped like a giant carved out beehive, the center of the vault was made into Jaz’s living quarters. Wrapped around her room were the small rooms of the other vault dwellers, the attendants of the growing giantess.

After four months Jaz had grown to 20 feet and her calorie intake dwarfed anyone else. Despite this, the vault was able to facilitate her needs. Not only was her body growing, it was also filling out. She had been scrawny the day the Overseer injected her. Jaz wasn’t even a scientist, thus she had always been given the smallest ration portion, which was deemed fair as she was just a mechanic. Thus, malnutrition had stunted her more feminine qualities.

The G-Strain changed all that.

Reaching 30 feet, Jaz had a bust that could milk an entire infirmary! By 50 feet, her butt was big enough for people to use as a trampoline. And by 60 feet…well, by 60 feet she was a virtual goddess of bountiful fertility. Jaz had loved this. She had always wanted to have more curve and not just be a twig like grease monkey. Now she had boobs that made me ogle and women to fume. She had more cushion for the pushin than any woman in human history. Most of all, she wasn’t just a grease monkey anymore.

Jaz loved every foot that she grew bigger. The attention from all the scientists in the morning, their tentative care for her like she was one of those pre-war celebrities…it was amazing. And yes, in time the envy she felt no longer made her cheeks blush hotly with embarrassment. As she got bigger, the waves of jealousy became like…like rays of energy that made her smile from ear to ear.

When she reached 60 feet, she spent that night sprawled on her floor, her legs splayed out wide, and she played herself. It had been nearly half a year since she had the privacy to slip her hand down her waist band. Since she was moved to the center chamber, she was too embarrassed to ever please herself. Now that was big enough to pick a man up with a single hand, her fingers wrapping around him, and lifting him up like a doll…well, it didn’t seem to matter to her anymore that she should care. That night she let the entire vault smell the sweet aroma of her arousal, hear the wet slick noises of her pink flower that could eat a man whole, and then finally the cry of her ecstasy that shook the walls.

It was also at 60 feet that Vault 78 realized that it had a caloric problem as the founders never knew just how many calories a growing giant or giantess would need in order to not only be sustained, but to grow…

Jaz glared at her stomach. “Maybe if not all of you had gone straight to my ass, I’d have pushed this damn thing by now.”

With that, Jaz got up and glared at the vault door. This was the last barrier between her and the whole world. A world that was for her. Not just some world that she read about and looked at pictures. Not a world that belonged to a past people that had blasted themselves into ash. No. Just outside that door, this big, stupid, oversized cog, was a world that could be hers. HER world.

If she could push this door open she would have the world at her feet. LITERALLY at her feet. She could shape the future. Direct mankind at her behest…and she wouldn’t starve.

Jaz’s belly growled at her, which made her steel herself before bracing against the door.

The giantess’s teeth were bared as she pushed. Her muscled tightened and coiled as she pushed. Flakes of red and orange fell down like snowflakes and the great steel contraption squealed in protest. Then, as she pushed herself to the limit, the metal began to move!

Suddenly a gust of fresh air blew into the vault, and the recycled air of two centuries was sucked out and back into the world it once came.

Jaz was suddenly left standing there in the doorway. Her eyes were wide as she stepped out, her feet crunching against sand and rock…and a bit of bones.

The giantesses had never seen the sky before. Never had she looked up to see an endless view. She had always seen a roof, a ceiling of restricting metal and concrete. Now…now she saw endless potential.

Looking down, she peered across the horizon, at the shambled world that was once ruled by man. The husks of his endeavors were strewn about. From them she could hear the pop shots of rifles and pistols and the shrieks of strange creatures.

All of these sounds seemed very small to her however, as they were very small.

Jaz licked her lips.

“I’m going to get so freaking BIG.”
