Gretchen grows bigger and stronger still

    by: Lvmsclgrls Author IconMail Icon
So as the lights remained on, Gretchen’s desires continued to drive her metamorphosis. As time continued to crawl outside, Gretchen tensed her body as her already incredibly strong muscles grew stronger. While her height increase slowed, her muscle density took a leap forward on the evolutionary scale. Her strength ramped up greater and greater and her muscles grew even larger, defying convention as every muscle group bulged and tightened and hardened until she was sporting muscles larger than any man her height had ever flexed. And then with a quick breath, those same muscles blew out bigger than those of any male heavyweight bodybuilder a foot taller! Her clothes morphed again as her muscles blasted to outlandish dimensions. Her shorts were now bright red bikini briefs and her top stretched taught around her globe sized pectorals, no longer covering the bottom or the top of her magnificent chest. The logo now said I FLIP TANKS WITH ONE ARM.

Chuckling menacingly as she could feel the strength of hundreds pound within her, Gretchen flexed her bicep again and football shaped muscle burst into view and rose up with a powerful peak half way up her thick forearm.

“Hmmmm. Bigger alright. And much, much stronger. But not big enough. Not strong enough! Time to go for the gold! Time to be a super girl!”

Gretchen closed her eyes and she could feel herself continue to change. Dreams of out lifting Superman were now being considered. Flexing muscles to cartoonish dimensions was no longer a silly thought. Lost in her moment, Gretchen barely heard the ding and had to open her eyes to see the lights inside the chamber dimming, the door opening. By now others were outside, including three of the boys from gymnastics. And when they saw Gretchen step out of the chamber, they looked on with awe and fear. Gretchen had grown to 5 foot 6 inches tall and her hair was long, thick, luscious and golden blonde. She looked prettier and definitely more confident. But it was her body that caused the boys, and every other on-looker to pause.

Gretchen turned toward the mirror and gasped. She had never seen muscles this big. Not on a girl, not on a boy, hell, not on anyone! Planting her small foot forward and pushing up on the balls of her feet, Gretchen pushed a leg forward and slowly flexed her leg. The slight tense caused her Herculean quads to balloon outward like steel girders, stretching her skin like saran wrap and showcasing rippling, mind-blowing definition. Calves bigger than cantaloupes bulges and jutted out with feathered muscle fibers and diamond hard definition.

“Now these are the legs of a champion. A super human champion! I could squat a tour bus with these babies!”

Twisting her hips back and forth, her fully exposed abs bunched into a mine field of muscle blocks, plates and uncountable pebble sized steel hard muscles. Giggling as the onlookers gawked, Gretchen leaned forward to crunch her abs with even deeper separation.

“I’d call these abs much better than a six pack. I’ll bet mortor shells would bounce off these babies!”

Tensing her chest, the material of her tight six inch wide tube top did little to hide the ocean of muscles stacked upon each other and thrust forward over a foot in front of her! Her top now read I FLIP HOUSES. FOR REAL. Her back was ridiculously wide, but curved with seemingly impossible feminine angles and sharp turns. Her T shape was from another world. Flexing her pecs up and down a few times, the twin globes of muscle filled chest muscles rippled and flexed into slabs of pure diamond hard girl power. Laughing now as she continued to tense her incredible chest up and down, Gretchen sighed with pleasure.

“I’d bet that my mighty chest is strong enough to bench press that tour bus! There’s never been a thicker chest flexed, much less something this massive being pounded forward by a teen-age girl!”

Pulling up her right arm, muscles few knew existed rippled, tensed and pulsed with one minor squeeze. As her forearm pulled up higher, her tricep dipped lower and her bicep expanded like a round, tiered wedding cake. Muscles stacked on top of each other in blatant disregard of biology as her bicep pressed up and over her mega thick shoulders, rising up toward her wrist and crackling with super strength.

“Now this is more like it! The strength and muscles of a real super girl! The muscles to show those boys what real girl power is all about!”

The three gymnast boys gulped, realizing that Gretchen had seen them in the mirror and was staring at them with a wicked smirk on her face. Releasing her impossible flex, Gretchen turned slowly toward the boys.

“Hello boys. Care to make any smart comments? Care to challenge me to a contest? Or should I just beat you all senseless instead?”
