As Amanda stood up, her new, muscle filled physique became apparent to everyone. Her massive legs jumped outward as she tensed her huge quads. In fact, due to the incredible density of her muscles, they sang a tune as she flexed them composed of a light squeal of stretching skin and expanding muscle fibers. Thighs bigger, stronger and sexier than any man or woman had ever flexed quivered, surged and consolidated into twin rippling masses of unreal female beef. Deep valleys ground around her incredible quads, meeting in the middle and blasting outward like two sides of beef. Giggling at the mummers of disbelief around her, Amanda stood on her toes for emphasis and send another shock wave of power down to her calves, causing them to spring outward into twin volleyball sized mounds of pulsing girl power. She could feel her toes dig right through her shoes, ripping the soles. Snickering, she shifted her feet, jutting her gigantic calves back and forth and in the process tearing her shoes and socks into rags.

Taking a step forward out of her socks on her small bare feet, she turned her head toward the onlookers and realized that she had retained her 5 foot 2 inch height, making her muscles even more awe inspiring across her short, slender frame.

“Well, that ought to prove that I’m now the strongest girl in school. Or am I now the strongest person on the planet?”

Walking back behind the bench, Amanda paused and brought her arms down to her sides and tensed her upper body. Waves of super powered muscles rose to prominence, singing another song of pure female might. The t-shirt and athletic top were now hugging the bottom of her muscle tits, exposing two inches of her striated spheres and a wall of abdominal muscles across her thin mid-section that looked like she had swallowed a set of pool balls. Her nipples were dramatically tenting the material to the point of rupture. And as she tensed her mega muscles, her back expanded and her chest pressed up and out, ripping the material up the sides, up the back and down the middle. Her sleeves tore up to her shoulders as she tensed her arms down at her sides, causing nine inch thick horseshoe triceps to split and expand as they continue to add mass up to her shoulders. The shirt also began ripping down the sides from the neck due to her bowling ball sized deltoid.

Amanda looked over at Jake and winked. “So Jake. Am I strong enough for you? Are my muscles big enough for you? Want to see a little more?”

Jake blushed as his erection pressed painfully forward while Samantha fumed, which only drove Amanda further.

And with one more tense of her incredibly buffed up torso, the material finally gave way to the dynamic grinding muscles underneath and with rips and pops, tore away from her body and fell to the floor around her. Giggling at the feeling of power, and the shocked expression and whispers around her, Amanda tensed her chest, first one side and then the next, dancing her basketball sized muscle boobs for those around her. The striations ripped across her massive mammories, showcasing the raw power they held.

“Not bad huh? These babies are big, bad and full of muscle. Stronger than any man alive and harder than steel. Want to see?”

Amanda inhaled, bringing her arms out to her sides, pressing her super human chest out even further as the muscles sang a song of power, showcasing every muscle fiber across her back, shoulders and chest for all to see. Licking her lips seductively, Amanda slowly brought her forearms up and tensed her fists, pulling even more strength and size into her biceps than any being alive. With ever growing power and might, Amanda’s thoughts shifted back to the Incredible Hulk. Unlimited strength and muscle size. To think that SHE now had that power. Staring at the bewildered Jake and Samantha, Amanda pulled her forearms up and they stopped at 90 degrees as her biceps had expanded to the size of volleyballs! Her triceps dipped low, digging into her lats as her biceps rose up over her shoulders and pressed against her thick forearms until the peaks throbbed up to her wrists! Jake’s jaw dropped open as he started to cum in pants right there in front of everybody! Samantha’s own jaw was open with shock and envy, but her expression changed to disgust as she glanced down to the stain in Jake’s shorts. Amanda held her laughter and chimed in seductively.

“Hmmmm. These massive muscle must please you, eh Jake? But it seems as though these biceps are what are driving you over the edge. What do you think they are now? 30 inches around, 35? Would you like to see them grow even bigger? Would you like to see them become even ssssssstronger?”

Jake’s eyes bugged out at the idea that Amanda could actually do that as Amanda purred.

“Well I can you know. They are already strong enough to curl this weight with one arm. Strong enough to curl TEN times this weight! And I can make them stronger too! Strong enough to lift Semi’s. Strong enough to lift freight cars. And all with a mere thought.”

And as she talked Amanda kept her eyes on Jake and pumped her biceps, adding an inch of girl fueled muscle each time, sending her peak higher, making her muscles denser, popping more muscle fibers to the surface and rippling striations across her mountainous, expanding biceps. And as she did, Jake continued to orgasm, messing his shorts further until Amanda had flexed her biceps up over her fists into twin towers of unbridled muscle perfection. Jake exhaled, fully spend. Amanda finally giggled and dropped her arms back to the sides. She looked back at the bar.

“Now as I was saying. This weight is well below my strength now. But that doesn’t mean I can’t use it to show everyone my awesome power.”

Amanda reached forward and pulled the bar off the rack with ridiculous ease. She giggled at how light it felt. And before that amazing feat of strength could register with the onlookers, Amanda started bending the bar. And even more amazing was the fact that she was bending the bar up! The huge steel disks, bending a bit down as they had sat on the bar now sailed upward as the metal screamed in protest as Amanda’s small finger dug into the steel bar and bent it without showing any strain. Amanda continued to bend the bar up until the weights met and then with a twist, crossed her arms, pulling the bar into a pretzel. Smiling, Amanda pulled the bar inward until all of the plates were touching. Amanda then placed the 1200 pound weight in the palm of her left hand and held it there for a moment.

“And if you thought that was impressive, watch this!”

Amanda reached up and began pulling the plates down with her fanatical strength. Her muscles leapt to attention, blasting out across her body in waves as the metal groaned and screeched. To Amanda the hard steel felt like putty. Putty she could mold with her superior strength! Her fingers dug into the metal easily and within moments the barbell was pressed into ball of steel! Amanda then shifted the ball onto her right hand and held it back with ease.

By this point, the entire school was buzzing and teachers were converging on the scene. Jake was already starting to sport another erection and Samantha was ready to cry with frustration. And Amanda was loving every second of it! With seemingly unlimited potential, Amanda looked over at the 1200 pound ball that felt like a beech ball. Smiling she reared back and tossed the huge metal ball upward and it crashed through the ceiling and up high into the air. The onlookers all gasped, including those teaches now watching. Amanda looked back at Jake and Samantha.

“That was too easy!”
