When the girl’s had come to the mall Becky’s mom had asked her bring along her younger sister, Olivia. At only 14, small and frail, she had just recently gone through puberty and to her dismay, she didn’t change as much as she hoped for. Her sister gave her a bit of hard time about it, but Rob would joke with her about being a little boy. This caused her already low self esteem to dip lower since she had a bit of crush on him.
So when Olivia saw her sister and her friends emerge from the Green Machine, she saw her salvation. Waiting until the girls left, Olivia moved toward the salesman.
“Excuse me sir. Can I try the machine out too?”
The salesman looked down at the 5 foot tall young girl and furrowed his brow. She stood there in blue shorts, flip flops and a pink shirt with a Batman logo. Her long dark hair fell over her thin shoulders as she stared up at him with her sad green eyes.
“Well…. I was going to start charging. But I suppose if someone as small as you can grow a little bigger, that can only help the sales job.”
Olivia lit up. Now she had to wonder just how big she could become. Becky was big and muscular, but Cassie was huge! Peering over at the controls, Olivia waited as the salesman adjusted the dials.
“Um. Just how big am I going to get?”
The salesman put on his best fake smile. “Oh, we’ll see. Remember, results may vary.”
As he was about ready to usher Olivia into the machine, a man distracted him, asking him some questions. With the salesman’s attention diverted, Olivia stepped toward the display and saw that height, strength and muscle were all labeled. He had set them to make Olivia 6 inches taller, as muscular as an average male athlete and just as strong. Olivia had other ideas. Darting her eyes to the distracted salesman and back to the display, Olivia pushed the strength dial up, unsure how high she left it. She then pushed the muscle dial up too. Just as she was about to reach for the height dial, the salesman turned back toward her.
“OK, little lady. Go ahead and step in.”
Olivia blushed from excitement and turned toward the machine, not willing to take any chances he would notice the changes. As she climbed in and the door shut, the salesman didn’t bother to look at the dials and hit the button. The normal humming was louder than before. Much louder. In fact, the energy being pulled into the machine was dulling the lights in the entire mall. The salesman looked nervous as the machines hum was now a roar. Glancing at the display, his eyes widened. Had he mistakenly set the dials that high? He was under strict orders not to exceed certain parameters. And he saw that not only was the strength dial up dangerously high, but the muscle dial was equally high. Two settings that could multiply the effects of one another. As the roar continued and the lights in the mall dimmed further, he swallowed nervously. Before the machine tripped the circuit breakers, the bell rung like a gong and the door opened.
Inside the machine, once the door closed, Olivia forced herself to take a breath. What had she done? She had no idea what fiddling with those dials could do. But as the machine cycled on, all those thoughts disappeared. The lights grew brighter and she could feel waves of energy sweep across her body. Letting out a pleasurable sigh, Olivia could see her body begin to change by looking at the mirror like surface of the inside of the chamber. As she grew taller, her once thin body began to morph into the chiseled frame of an Olympic athlete. She blinked as her outfit changed too. The shorts became athletic spandex, pulled tight around her growing curves and surging muscles. Her top pulled up and began to shrink, exposing her six pack abs and her now bulging arms. The Batman logo had changed to a Spiderman logo. Olivia smiled at the prospects.
“Hmmm. I wonder if the logo is an indication of strength. Am I really as strong as Spiderman? I know I feel stronger.”
As the seconds ticked away and the energy intensified, Olivia continued to sense her strength swelling as her height inched up and her muscles expanded. The shirt morphed into a tight spandex athletic top barely covering her surging pectorals and widening back. The sleeves were now two inch wide straps that ran over her thickening shoulders. The logo was now that of Wonder Woman. Olivia gasped.
“Wonder Woman? Am I really as strong as Wonder Woman? I know my muscles have eclipsed her level, so if I am, little Olivia is now a super powered Olivia!
As the last few seconds finished off and Olivia rose up to her new height, she had to close her eyes as the orgasmic feeling of strength and power swept across her body like a tidal wave. Her excited nipples tented the material of her still changing top as her muscles continued to build to super hero proportions.
As the bell rung and the door automatically opened, Olivia opened her eyes and stepped out, glancing at the stunned salesman and smiled knowingly.
“Sorry mister, but if I was going to get more muscular and stronger, I wasn’t going to be second fiddle to my big sister anymore.”
The salesman’s eyes grew wide and his jaw dripped at the sight of her. He was told of the potential of the machine, but he wasn’t warned that the machine could produce someone like this once thin young thing. She was massive. No, she was humongous. He paused, unable to come up with the right terms to describe her. He could only look on and ponder what he had done.
Olivia chuckled at the reaction of the salesman as she turned toward the mirror and the weights and gasped.
The image staring back at her was something only seen from morphs on the web. Her body was covered with the most insane group of muscles that had ever been flexed. Her gigantic legs sported massive, twelve inch thick thighs and 30 inch circumference, diamond calves. The flip flops were some type of athletic sandals that barely covered her small feet. The magnificent thighs curved up to a narrow stomach that sported more muscles than were in any anatomy book, riddling her midsection with seemingly uncountable bumps and grooves. The same narrow midsection roared out into a mind blowing wide back bunched thick with slabs of girl muscle. Her chest was a spectacular display of pectoral muscles and steel hard breasts pushed out into twin spheres of power, 18 inches thick, covered with a spandex bikini top. On one breast was the Superman S, while the other side had Hulk in green letters. Olivia was nothing short of a Super She Hulk!
Looking into the mirror, Olivia smirked and flexed her biceps, causing twin mountains of muscle to rise up like missiles of pure girl power! Her mighty peaks blasted up over her fists as tattoos of mushroom clouds flashed on her biceps, making booming sounds and shaking the foundation of the mall! Giggling at the realization, Olivia flexed down again, sending her biceps peaks soaring up higher than the top of her head, with multiple mushroom clouds flashing on her larger biceps, causing a louder rumble to emanate from her super powered muscles. Now laughing, Olivia pulled her forearms down further, flexed her tiny fists hard and pulled her massive forearms back up, detonating her biceps to dizzying heights over a foot above the top of her head as a video of an asteroid slamming into a planet exploded on her towering biceps as the sound of multiple cannon fires roared from her reality warping muscles!
Releasing her mind altering flex and pulsing her pecs to make them dance, Olivia nodded her head with satisfaction. Nobody would be making fun of her anymore! Reaching down, she picked up a steel dumbbell and giggled at the weightlessness of the 25 pounds. Bringing her other hand into play, Olivia squeezed down, and with a satisfying metal squeal, crushed, twisted and compress the dumbbell into a ball within second. Dropping the weight to the ground with a thud, Olivia turned back toward the shaking salesman and practically floated forward.
“Guess I’m going to have to find something a bit heavier and sturdier to test this super mega powered body. I’m not sure what that will be, but I’m going to have fun trying!”
As she flipped her thick dark hair over her football sized shoulder she walked back into the mall just as Randy turned the corner. He slammed right into Olivia and bounced off her mega powered muscles like a pillow against a brick wall. Randy was knocked backward and onto his behind. He groaned, looked up and was greeted by the smiling eyes of Becky’s younger sister Olivia. And it was clear she had just come out of the Green Machine. She was about 6 inches taller, but her muscles were bigger than any Randy had seen on ANYONE. EVER! His eyes nearly bugged out of his head as Olivia flexed her muscles slightly, causing them to crackle and boom. But it was the smile that formed across her beautiful face that worried him even more. The smile was not all that pleasant.
“Why, hello Randy. Fancy meeting you here! You know, I’ve been wondering how I can try out my new muscles and super strength. Any ideas?”
Randy gulped. He didn’t like where this was headed.
