Stephanie feels Laura's biceps

    by: Lvmsclgrls Author IconMail Icon
Once Stephanie reached Laura, she had to pause. This monster muscle girl was shorter than she was. Yet she was displaying more muscle than any person she had ever seen. Stephanie was drawn to the power, the confidence and the muscles. Stephanie had always like big, strong muscles. She just had never imagined that she would meet a girl that met her base desires.

So as she looked down into Laura’s smiling eyes with wonder and watched the incredible bicep flex up into a mountain of she muscle, Stephanie practically panted as she reached out to touch the rising peak. Tentatively placing her fingers on the upper bicep Stephanie brought both hands into play as Laura tensed harder, infusing an extra two inches of pure muscle into her upper arm. Stephanie’s hands jerked slightly and she let out a surprised “Oh”. Laura giggled.

“So Stephanie. What do you think? Are my biceps bigger than Greg’s over there?”

Stephanie, wide eyed and enamored, simply nodded her head as she continued to probe Laura’s arm. Another hard squeeze by Laura shot her bicep up even higher, pushing her forearm away from her now monumental 30 inch bicep.

“Hear that Greg? Your little sister is flexing up a bicep bigger than yours. Bet you never thought you’d see that happen, huh?”

Greg didn’t even nod his head as he stared on with disbelief. Laura grunted lightly and looked at her ever growing bicep. “Go ahead and try and squeeze it Stephanie. See if you can.”

As Laura’s muscles continued to grow in size and strength, blasting forth more muscular than the biggest of bodybuilding men, Stephanie tried to squeeze down. But when her initial attempt failed, Stephanie tried with all of her strength, but was unable to press into Laura’s muscle at all. Stephanie’s face turned red from the effort and she let out a defeated sigh as she pulled her hands away and stepped back, staring with awe and a bit of lust at the power Laura clearly had. Laura smiled and flexed up her bicep again, this time up to 40 impossible inches around!

“Pretty hard, huh? Like, oh, I don’t know. Steel?”

Stephanie nodded and as Laura looked toward Greg she narrowed her eyes to a more dominating stare as the color escaped his face. Laura snickered and bringing her arms down in front of her, flexed her chest, pulling her massive pectoral slabs up and down, causing her chest to put on a show that put Greg’s to shame. Standing back up, Laura pulled her arms up into another double bicep pose. The incredible growth was nearing an end and her strength was now out of this world.

Back up on her toes for a final flex, Laura’s 5 foot 4 inch height seemed even shorter, as her enormous muscles had piled up onto her slim frame like massive rocks, pressing out in every direction in defiance of normal human anatomy. Her feet were the same size they always were, which made the curve to her volleyball sized calves even more incredible. And those pink balls of power curved into the same narrow knees that were practically engulfed by her beyond massive quads. Her thighs were deeply separated, thick as a bag of water softener salt and two incredibly feet wide each. These huge pillars of female muscle dramatically curved into a stomach that was now even narrower than her former 30 inch flabby midsection, but was covered completely with muscle blocks to put any man or woman to shame. Her incredible abs whipped back out to an insanely wide back now flexed to nearly four feet wide, while her equally massive chest pumped up with twin basketball sized jagged pectorals that bristled with impossible strength and hardness. Smiling as she flexed up her biceps into two female mountains of fury, her triceps dipped low into her lats and her biceps exploded upward, bigger than her head, rising up to touch her fists! Laura was now simply the most muscular person to ever have lived. She was an 18 year old super girl. And she loved it!

“So Greg, what do think of your sister now? Not so puny anymore, huh?”

Greg, Stephanie and many onlookers nearly swallowed their teeth. Laura laughed and releasing her flex looked around. Vanessa was in the crowd to, holding her own phone and looked less shocked than everybody else. Laura grunted nervously and smiled at Vanessa.

Looking back at Greg and Stephanie, Laura shook off her concerns. She had a captive audience and was unsure as to what to do next. Thinking quickly, Laura decided to.

You have the following choices:
