Sarah marched over to the still stunned Dennis, her humongous muscles surging and swelling to ridiculous proportions as she walked. Sarah was now wearing a mini super strong black rubber bikini, designed to withstand her normal movements. Nothing on earth, however, could withstand her muscles once she started flexing or lifting weights. She had long passed super strong and was now nothing short of ultra strong. Bending steel girders bored her two years ago. Lifting tour busses was a breeze. She was juggling tanks two months ago for fun. The army was now so afraid of her that they no longer wanted to test her strength as she only continued to grow stronger with every lift. It appeared that Sarah had no limit. That no matter what she was asked to lift, given enough effort, Sarah was soon able to lift it. And as she grew stronger her muscles would grow larger, harder and tougher. She now laughed at tank shells and complained that surface to air missiles tickled.
So with the army calling on her less and less, in order to keep her own obsession of ever increasing strength in tack, she had demanded a work out area. The basement was now designed with gravitational devices meant to give her proper workouts, but they had already had to upgrade it twice. And as her strength and muscle power still had no limit in site, Sarah also felt the need to subjugate everyone around her to keep herself occupied. She had no real desire to rule the world just yet, but was able to gain perverse pleasure in controlling people. When they started lifting together a few years ago, Marcy actually kept up for a while, but it soon became apparent just who deserved the label “Super”. And to top it all off, Sarah had blossomed into a vision of beauty. Her 5 foot four inch mega muscled frame was topped with a face with piercing blue eyes, long blonde hair, full lips and overall gorgeous features. Her looks alone were enough to land a modeling job, so add that with seemingly unlimited strength, a mean streak and massive, bulging muscles and she was the recipe for the ultimate bad girl. Sarah was unattainable, untamed and completely aware of who she was and what she could do.
And yet her worthless brother was actually questioning her authority. This was unacceptable. She could crush his body without even trying, but that would only put in him in the hospital. And how could he service her from there? No, there was a much better way to control Dennis. Sarah knew full well his lust after female muscle and strength. It was obviously why he was trying to go after Marcy. But if he thought Marcy had the body he lusted after, she’d easily show him what real muscles and strength were all about. And Dennis would quickly be hers to control. So with a stern look on face, she stared up at the stunned Dennis.
“Strip.”
Dennis gulped again, trying to comprehend just what had happened. He had stolen a glance at the gym and the noticed a large electronic box mounted to the wall with a large digital display. He also noticed the large picture of Sarah, completely nude, holding up a train engine. With one arm. And the picture was two years old. Looking back at Sarah he now realized what he had done. Sarah was super strong. No damn it, Marcy was super strong. Sarah was super duper strong. She was the ultimate embodiment of female muscle and power. He could only contemplate what Sarah had in store for him. Looking down at the camera, he looked up at his simmering sister.
“Last chance Dennis. Or I have your dream girl over there start breaking every bone in your body one at a time.”
Putting the camera down quickly, Dennis hoped he would have another chance to use it to correct things, but now he started taking off his shirt while shaking. Sarah walked over toward the control box and flipped a large switch. A loud hum was generated and the digital display grew bright. As Dennis paused with his shirt off, Sarah frowned at him.
“Did I say stop?”
Dennis pulled off his jeans next, so he was standing in his boxers and socks. Sarah, her mood changing slightly, dropped her voice.
“Your shorts too mister.”
As Dennis blushed and his body shook, he nervously started to pull down his boxers, just as Sarah started flexing up her body. Mega powered muscles began to bulge across her knockout frame. Dennis had to blink slowly to take in Sarah’s otherworldly physique. He was so confused and scared, that he hadn’t had time to realize just how beautiful, how curvy and how over the top muscular his sister was. With her left hand on her hip, Sarah pulled up her right arm and slowly began to pump her biceps. Her legs casually flexed into waves of inhuman muscles, distended, petrified to twice the size of the biggest male bodybuilder, yet flowing with feminine curves and smooth, ivory skin. Her abs were narrow and completely covered with bumps, caverns and muscles Dennis never even knew existed. Her mega muscled basketball sized pecs pushed the bikini outward with a groan as her lats widened passed four feet and her shoulders and traps bulged up her thin neck. Without so much as a single flex, Dennis was already overtaken by his sister’s complete muscle superiority. This caused Sarah to smirk as she noticed the effect she having on her brother already.
“Every day I grow stronger Dennis. Every day I pump these muscles up to new heights of power and glory. These girl muscles are the biggest, strongest, hardest, toughest muscles to ever be flexed by any being on the plant. I’m stronger than any man, animal or machine that ever existed. I could toss battleships around like empty cans of soda, Dennis. There hasn’t been anything I’ve tried to lift that these muscles didn’t grow strong enough to lift. Nothing can stop me Dennis. No missile, no bomb, no tank. And every day I grow stronger. I lift more and more and more, and never get tired. These magnificent muscles never stop growing stronger. This incredible teen-age girl body never stops becoming more powerful. Now come over and feel the muscles that can lift anything you can dream of Dennis. Come over here and touch the biceps of a REAL Supergirl!”
As Sarah continued to talk, she was producing the desired results. Dennis was growing an erection. And by the time he shuffled toward Sarah and the bicep she was starting to flex, his dick was already hard. Dennis brought his hands up to her bicep and placing them on the 32 inch ball of might, he trembled with fear and desire. Sarah licked her lips.
“Feel the hardness Dennis. Try and squeeze my bicep. There isn’t a harder substance on earth. I’ve placed titanium bars between by bicep and forearm and listened to metal buckle, squeal and crush to liquid with the power of my mighty flexing muscles. I can crush diamonds between my pectorals. And every day these muscles grow harder Dennis. Feel the power pulsing in my muscles Dennis, get a taste of the ultimate girl strength of the strongest being on the planet!”
As Dennis started to breath erratically, his dick began to throb and leak. And then Sarah tensed her bicep, sending waves of strength and power into her muscle, adding six inches or raw female fury into her bicep with that one minor flex, pulling Dennis’s hands up higher and spreading his fingers apart. He could feel the power humming below her thin skin as she flexed, causing his hands to tingle.
“And I can flex these muscles bigger than any man alive. I can flex them bigger and bigger.”
Another flex pushed them up another 8 inches, causing Dennis to moan as he started to cum. Sarah knew full well that even though her other muscles could flex up to monstrous size as well, that her biceps would do him in. Dennis was nearly hers already and she had barely started. She pulled her wrist back slightly and tensed again, sending another shock wave of muscle throbbing across her arm. Her bicep was now the size of a basketball and was over 50 inches around! One more flex jerked Dennis’s arms up higher as her peak now pushed up above her head! Her bicep was now 65 inches of pure muscle glory.
“I can flex my bicep to 6 feet around without hardly trying, Dennis. I can flex it up bigger too. And the bigger I flex it, the harder it becomes. I’ve torn through two foot thick re-enforced steel girders with my biceps alone. I’ve wrapped steel chains used to pull battleships around my biceps and shattered the links by flexing down. And every day these babies grow bigger Dennis. Every day I flex them to new, glorious heights. My strength is unlimited, Dennis. My muscle power is beyond anything on earth. My muscle expansion is greater than any scientist can explain.”
By now Dennis was weak in the knees, and he was barely able to hold on to Sarah’s mighty bicep, now up beyond 72 inches around and over two feet tall! He had cum twice and could only think of Sarah and her super powered body. Another flex pushed her bicep another two impossible feet to 96 inches around!
As Dennis came a third time, he fell backward, his fingers rubbing against Sarah’s ultimately hard biceps as he fell. Sarah looked down at him, smiling ruefully.
“Now Dennis. Is there any question as to who the boss is around here?”
Dennis, shaken and stirred, nodded weakly.
“Good then. Because I’m ready to work out a bit. Think I’ll start with my biceps. I’ll give you the privilege to watch and yank off today for my pleasure to ensure you’re mine. Because if you ever try and cross me, there’s no man or army on the planet who could save you.”
Dennis let out a nervous sigh and bit his lower lip. Sarah smiled at him with dominance and spoke with unwavering command.
“Marcy. Get over to the machine and set the gravity to 1000 times. Time to set some new records.”
Marcy, having cum herself from Sarah’s display, anxiously scurried over to the controls for her master.
As Sarah moved toward a large weight set, she looked at Dennis, who was still stunned and breathing heavy.
“The only regret is that there is no longer anyone or anything left to challenge me. What I wouldn’t give to try out my powers on someone who could take some punishment.”
Dennis was still in a haze. He looked over at the camera. He could do that, he thought. Or for the moment he could simply enjoy watching his sister lift insane amounts of weight. He also shot a quick glance toward Marcy, imagining if perhaps she could be the one to challenge and perhaps surpass Sarah. As he looked back at Sarah and let out a passionate breath, he decided to…
