Janey paused, smiled and twisted the dial up to 100%.

“This way, they’ll NEVER become as big and strong as me, since I started out bigger and stronger. Those two won’t know what hit them when I’m done!”

Janey turned the gun toward herself and pulled the trigger. The now familiar bright green flash of light shot out of the gun and engulfed Janey. Janey tossed the gun onto the bed and turned toward the mirror on Amanda’s door as she felt a pleasurable warmth fill her body. The pleasurable warmth soon became a near orgasmic heat as Janey could feel incredible strength building and building within her. Moaning with pleasure, her nipples became engorged, pressing her bra below them and pushing the nipples hard against her shirt, nearly piercing the material as they crystallized into twin bullets. Her breasts started expanding, spilling out of the v-neck and ripping the shirt down the center and along the sides as the soft breast tissue was quickly replaced with rock hard, super strong muscles. Within moments her bra snapped under the strain as her lats widened and thickened to back up her massive chest.

Janey groaned as she could feel her muscles pulse and tense and throb and flex, growing harder, stronger and bigger. “Oh my god! This is the best feeling ever! I feel so strong! So powerful! Like there’s nothing I can’t do! Nothing I can’t lift! Sally thought she could toss me around, huh? I’ll toss her to the next state!”

As another wave of power swept through her body, Janey squealed as her legs exploded with muscles, doubling in size to hard, defined, pillars of power. Mammoth thighs burst forth and calves the size of canned hams tore her socks. Standing on her toes, she injected even more strength and size into her legs, expanding her thighs out into twin sides of beef and her calves toward the size of pumpkins with the strength to squat an air craft carrier!

“Holy crap! I’ve never seen legs this big and muscular on anyone! These make Brad’s look like toothpicks! And their bigger than Sally and Amanda combined! And I can feel the strength in them. Strength to jump over a mountain! Strength drop kick those two losers to the moon! Hah!”

Janey’s attention moved back to her upper body as the v-neck continued to rip down the middle against her ever expanding torso. Grunting, Janey reached out and tore the ruined top off of her body, exposing her bubbling, pool ball abs and her steel hard mega muscled boobs backed with thick, writhing pectorals. “Now THIS is a chest! No sag in these babies. I’ll never need a bra again!”

Janey sucked in a breath as yet another wave of strength bolted into her muscles, causing her to tense her chest again sending striations running across her basketball sized muscle breasts, filling her chest with even more strength and power. Her nipples hardened into diamonds, tingling erotically. She flexed her pectorals and her chest rose to her chin. She placed her arms to her side and tensed, sending her triceps out into huge horseshoes, 6 inches thick. Her chest crackled and surged forward with 18 inches of pure muscle cleavage and the strength to bench press the town square!

“So those two bitches thought they had big chests did they? Well look who’s on top again! These bad boys are the biggest, hardest, densest set of muscle boobs the world has ever seen. I’ll bet I could smash through a bank safe with this chest alone! My nipples could cut through steel! Hell, I could balance the entire bank on my chest without breaking a sweat!”

And through it all, Janey’s body continued to transform, continued to grow stronger, continued to grow more powerful. Sally had small fit muscles and grew as large as a male bodybuilder with a 10 percent shot. Amanda had weak, normal girl muscles and had groan twice as big with a 30 percent shot. Now the gun was working with a very fit and strong girl who had dialed the gun up to 100%. Superman himself would soon have trouble dealing with the result. The Hulk would soon be at a loss to match her muscularity. For Janey’s muscles continued to grow harder and stronger. Denser and stronger. Bigger and stronger. More defined and stronger! Stronger and stronger! Her muscles were growing hard enough to withstand nuclear bombs! Dense enough to withstand the pressure at the center of the sun! Big enough to dwarf Godzilla! Strong enough to toss around sky scrapers. Strong enough to lift mountains! Strong enough to lift continents!

Her body shuddered with orgasm after orgasm as wave after wave of strength and power continued to pound into Janey’s mega muscled super strong body. Janey growled and pulled up her right arm. The lemon sized bicep had already grown to the size of a cantaloupe. And Janey hadn’t even flexed down yet.

“So Sally thought those 25 inch biceps were big and strong huh?”

Janey flexed down and her bicep surged up to her wrist. Muscle fibers pulsed across her biceps and veins rose to the surface. “And Amanda thought she was big and strong when her biceps reached the top of her fist.”

Janey pulled her forearm down and flexing hard, brought her arm back up, and blasted her bicep to the size of a watermelon. The peak pressed up above Janey’s head! “And the Hulk thinks he’s big and strong when he flexes biceps the size of boulders.”

Janey pumped her arm once again, feeling another rush of strength pore into her muscles, more than doubling the size of her bicep, infusing her muscles with unthinkable strength and power! Janey laughed as she looked up at her mountainous bicep that now tickled the ceiling. “King Kong think his biceps are big just because he’s 50 feet tall!

Janey flexed her bicep again and with a mighty crunch, her bicep blasted through the ceiling, through the attic, through the roof and up into the sky! She continued to flex down, sending more and more strength into her gigantic muscle as it rose 10 feet high, 20 feet high, 30 feet high! The air sizzled around her mega powered muscle as the strength to curl mountains continued to pound into her other worldly biceps!

“I’ll show those two what a big bicep is all about! I’ll show everybody! I’ll destroy ARMIES! I’ll curl this entire state with the biggest biceps ever dreamed!”

And still her bicep rose higher, climbing to 40 feet tall! And then with one final earth shaking flex, Janey detonated her bicep up to 1200 inches around and 50 feet tall!

“Ha! My bicep is now as BIG as King Kong! My muscles are stronger than any being in the GALAXY! I can FEEL it!”

As the waves of strength finally slowed to a stop and the red hot power pounding in her muscles finally cooled, Janey released her flex and her bicep receded, pulling all of the cosmic power back into her 5 foot two inch frame. Janey now glowed as her naked body pulsed with power across every muscles of her magnificent teen age girl body. Every small movement engorged her petrified muscles with unthinkable strength.

“To hell with Sally and Amanda! I’ve got bigger fish to fry! Time to take this pumped up super body for a test spin!”

Janey bent down and with a small tense of her titanic muscles blasted up through the roof, sailing into the air and landing half a mile away with explosive force, cracking the pavement and sending out a wave of destruction all around her. Smiling as she looked around, her thoughts had slipped passed Shally and Amanda. Those girls were beneath her interest now.

Her vision now enhanced to super human levels, Janey eyed the maximum security prison for the most powerful villains on the planet. Giggling at the prospects, Janey soon floated upward, her strength and power no longer held in check by the force of gravity. The prison was 100 miles away. Janey soared up a mile into the air and with a sonic boom flew toward the prison and Doomsday, the Abomination and others. She smiled at the prospects. She’d destroy the strongest villains, then aim toward the heroes. New Krypton was next. Thousands of beings as strong as Superman to test her strength. She could hardly wait.

“They’re all in for a surprise when Ultimate Janey shows them who’s boss!”
