This is my first try at a story here. I've always liked movies about giant animals terrorizing cities. Well now, mankind (womankind I guess) is fighting back.

Life had been hard recently for Tom Noman. The creature known as Godzilla had risen from the deep twice already, and leveled two major cities, rising outside of Dubai and then London. Deep sea sonar had been tracking the monstrosity and they had found it was coming for his home, New York City. As one of the best scientific minds in the country, it had of course fallen to him to produce some defense against the creature. Bombs and missiles were too dangerous for use in the city, and bullets just bounced off of its thick hide.

He had gone through a few robots, but none were sophisticated or powerful enough to stand up to the old dinosaur for more than a second before they were worth less than their weight in scrap metal. He needed something alive, something just as strong and huge as the mammoth reptile.

Tests had begun, starting with lab mice as these tests generally do. It took weeks of effort, but he managed to get one to grow to three times its ordinary size. The female had become a dominating force in the cage, but was strangely mounted most often by the now diminutive males. Strangely, the process didn’t seem to work on males of any species. The chromosomal difference made the serum he was creating incompatible with their bodies, and they would generally die or become comatose.

Soon, he was onto larger animals until he had a deer the size of a buffalo. It was at that moment, an alarm rang in his research center. He looked over to the wall, which spoke with a thunderous voice, “Dr. Noman!”

“Here sir.” Replied Noman quickly

“It’s happening. We need results now. The monster is fifty miles away, and gaining fast.” The voice spoke with the upmost authority. Tom had never learned who was on the other end, but there was no doubt in his mind it was a man with great power who would like to preserve it.

There was a silence. “Sir… I can’t guarantee results. You’re demanding I use this on a human. I don’t know if it’s reversible, I can’t tell if it will have...”

The voice cut him off, “It doesn’t matter. What you will do, is use it. Find a subject, someone you trust implicitly, and use it. I don’t want two monsters.” After a hiss of static, the voice disappeared.

Sighing, Tom gathered all of his serum together. He didn’t know if it would be enough, but it would have to be enough for now. Picking up the phone, he made the most important call of his life. “Holly? Meet me ten miles west of New York as soon as you can. It’s urgent. Thanks, I knew you’d understand.”

Holly was his girlfriend, a bit neglected for the past few weeks as Tom worked, but he knew that she would still want to talk to him. She understood his business, that it controlled him sometimes. And so, she hopped in her smart car and drove off. She knew the place, it was bridge that they had made love under for the first time. In twenty minutes, she was there.

Tom was already waiting for her. Reclining on a blue sports car parked in the grass, he saw the tiny red car approaching. He marveled for a moment at how nice it was just a few miles from the city and the suburbs. Traffic had been incredibly light today; people had been warned off of the streets already by the news casts.

The smart car parked and Holly stepped out. She was dressed for work right now, a tight pants suit and a pair of designer glasses on her angular face, with a pair of significant heels on. Her and Tom were the same height, but with the heels, he stood a few inches shorter than her. They kissed for a moment, before she asked, a little businesslike why he had called her out here.

“You know about Godzilla?” He didn’t have to wait for the nod, “Well, he’s coming for New York.” Or the gasp, “I’ve been working on something to stop him. I tried everything, I really did. I wouldn’t ask this of you if I didn’t have any other choice….” He stopped, unable to continue before she pulled his chin up, leveling his eyes with hers.

“It’s a serum. In animals, it’s caused massive growth and strength increase, the development of a nubile body.” He didn’t mention the huge increase in sex drive he had noticed, he’d let her figure that out on her own. “Every bit I have left is in my car. I want to give it to you. I’d use it on myself, but it only works on women, for genetic reasons. I trust you, more than anybody I know.”

Holly bit her lip. What was he asking of her? To become a monster to fight another monster? She was athletically framed now, a body she had never worked for, over six feet tall in her heels, but she had seen pictures of Godzilla. He would tear her to pieces!

“Please Holly…” he practically whimpered it as tears filled his girlfriend’s eyes before she finally nodded.

“Hurry before I change my mind.” She said. He was already at the trunk, opening it to pull out a series of syringes. There were three, he hoped it would be enough to settle this.

He swabbed her arm with alcohol, pulling off the jacket to do so, raising up the cuff of her shirt underneath. “One… two… three.” He said, pushing it in and downing the plunger in the same motion. The clear serum flooded her veins and she collapsed instantly and stopped moving.

Panic nearly stopped his heart. What had he done? Had he killed her? Fingers probed her neck, feeling for a pulse. It was steady and even, and she gasped when his hands touched her neck. She pulled herself to her feet. He found himself craning his neck more to look at her. And more, and more. It was working!

Alarm settled on her face as she looked down at hands that were far larger than his now. Her feet burst the bond of her shoes quickly, and she looked like a kid about ready to hit a major growth spurt. They became larger than any professional basketball players, the rest of her body waiting as she grew. A few moments later, her calves began to bulge out against her pants, then her thighs, and hips, and torso, her arms and neck and head. She grew from the bottom up. Tom watched in amazement, taking a step back as she grew.

It was an amazing show. The look of panic had been replaced by ecstasy, the pretty blonde’s features twisting in orgasmic agony. She collapsed to her hands and knees to the sound of tearing cloth as her clothes were ripped to pieces. No muscular development, noted Tom with distaste. He liked her body, but she’d need to be a lot stronger when they were finished here.

She panted heavily, the ruins of her clothes not even trying to hold together, an impossibly stretched set of undergarments hiding her from view. She raised her head, amazed to find it level with her boyfriend’s. With a groan, she stood, his head not even reaching her waist now. Delight crossed her features as she rubbed her arms and torso, though she was proportionally the same, she had to be about thirteen feet tall.

“Thirteen feet, seven inches. Eighteen hundred pounds.” The robotic voice of Tom’s scanner snapped her from her reverie. She squealed then, and her thoughts went tumbling on how people would act around her now, wondering where she’d get clothes, ignoring the fight to come.

Tom shook his head, prepping the second syringe, “Not nearly enough still sweetheart.” He said, rubbing her thigh with alcohol. “The second dose is a bit more powerful, it ought to get you in shape for this.” He was about to inject her before he went back to his car and pulled out what looked like a large roll of black fabric. “Put this on. It’ll grow as you do.” After all, he didn’t want everyone seeing his naked girlfriend prancing around downtown.
