This choice: Like brother, like sister, Steven and Rachel are now both muscular and huge! • Go Back...Chapter #5Like brother, like sister, Steven and Rachel ar... by: Lvmsclgrls   Rachel not only wanted to have big muscles just like her brother. She wanted bigger muscles. Big, bad, earth shaking muscles to put any man on earth to shame! Now THAT would be cool.
Steven handed her the necklace and she put it on, smiling up at Steven. His 5 foot 10 inch frame carried the 200 pounds of muscle like a football linebacker. Her 5 foot tall frame was thin and weak. Her blonde hair fell over her shoulders of the blue t-shirt and her thin legs stuck out of her shorts down to her bare feet.
Rachel then made her wish. She’d get the muscle size of her brother to start. Then she’d really have some fun. And then she wondered how strong he was. With the necklace on, she could tell his strength matched his muscle size. He was strong, but no stronger than any man that size. Rachel giggled again. She would have none of that. Oh no. She would have massive strength too. Thinking of the Hulk video game she had playing she figured that she wanted that kind of strength! Or perhaps that of Wonder Woman from the Justice League game. But first things first. She wanted muscles to match her brother. And by concentrating on that, Rachel’s muscles began to pulse and grow.
Her legs quickly piled on slabs of strong, rippling muscles. Her calves expanded into softball sized balls of power. Her thighs ground forward to match those of a world class sprinter. And along with her muscle filled glutes, her muscle filled lower body ripped her shorts up to the waist. Her shirt filled with muscles immediately and just like her brother, exploded off her body and fell to the floor. Rachel was sporting a massive torso to match her brother’s. Her chest was strong and thick, her back was muscular and wide, her shoulders and traps bulged up and her abs were a six pack of solid muscle. Rachel smiled as she brought up her right arm and flexed her bicep. The muscle consolidated and crunched into a ball of muscle 15 inches around. Stripped of fat, the bicep split was clearly seen, the tricep dipped low to match the large mound of muscle resting on her arm. Rachel looked up at her brother who nodded his head, admiring the muscles that matched his own.
Rachel’s blue eyes flickered mischievously.
“Hey, big brother, let’s compare biceps.”
Steven stood in front of her and leaned to the side, flexing his arm so that they could compare. His arm bunched up and matched that of his little sister, maybe looking a bit bigger on his larger frame.
“Not bad Rachel, you’re bicep is about as big as mine. Nobody will messing with us at school any more.”
Rachel giggled as she now wished for muscles bigger than Steven. And just as he was about to release his flex, Rachel’s arm twitched, and began to slowly grow, punctuated with an unearthly throb matching her heartbeat. And each beat pushed the bicep a little bigger. Soon her bicep matched his, then it grew bigger, reaching 16 inches around in a few seconds. Steven’s eyes widened as he could see her bicep peak rise up over his. A few moments later, the peak rose higher, exposing more of her massive bicep behind his. At 17 inches around, Rachel’s bicep was clearly larger, at 18 inches there was no doubt as to who had the bigger arm. Rachel giggled.
“Hmmm. It looks like my girl arm larger than your man arm big brother. But why stop there? I’m sure there are still people with bigger biceps. And stronger biceps. But not for long!”
Rachel started pumping her arm, pressing a full inch of girl muscle into her arm each time she reached the apex and clenched her fist. Steven remained frozen in his spot, watching with fascination at the transformation of his younger sister. 19 inch biceps were soon 20 and then 21 inches. And with each flex, Rachel wished to double her strength. By the time her bicep had reached 22 inches she was the strongest human on the planet and her muscles began to crackle as they grew harder and denser. Soon Rachel’s bicep was rising up higher and higher above Steven’s to 24 inches, to 26 inches! He had never seen a bicep this big! And each time she pumped her arm, the bicep grew bigger! At 28 inches, her arm looked surreal. At 30 inches it was completely eclipsing his, having now doubled in size! Steven finally released his flex and turned around. Rachel stood there, holding her incredible flex. Steven gasped. All of her muscles had doubled in size! She was sporting muscles to put any bodybuilder on earth to shame! Massive, tree trunk legs curved wickedly into a narrow set of steel belted abs and back out into lats as wide a door and a twin bowling ball sized set of pecs! Her left arm flexed a massive horseshoe tricep that jutted out six inches and right arm was now flexing up a gigantic 32 inch bicep that peaked up near her wrist! The muscles were all rippled across her flawless skin and with her small joints looked gigantic. Her beautiful blue eyes sparkled and her blonde hair shined. And not only that but these massive muscles carried the strength of over 100,000 men!
“Now we’re talking some REAL muscles!”
Releasing her flex, Rachel grabbed her brother’s arm and quickly pulled him outside. Reaching down at the corner of their house, Rachel slammed her arms into the ground, gripping the foundation. She looked over at her stunned brother who was rubbing his sore forearm bruised from her steel grip.
“And not only that, but we’re talking about some REAL strength!”
Rachel pulled against the house and with explosive force, ripped the entire house out the ground shooting dirt and rocks all around. Standing back up, Steven’s eyes went wide and his jaw dropped as his little sister hoisted their house up over her head!
“And this isn’t all that heavy either! Just image what else I can lift Steven! Tanks! Trains! Maybe even skyscrapers!”
Rachel carefully placed the house back down, not looking to destroy it. At least not yet.
“So big brother, now that I’m the strongest, most muscular girl on earth, what ever shall we do next?”
