Shoving the beaten Arnold to the ground, Tricia, his once best friend stepped closer.

“And what was it that Popeye did when he ate his spinach? Something I know you’ll just love! Something I know will drive you absolutely crazy!”

Pushing out one hip, Tricia brought her arm out and super powered muscles bristled forward, morphing her tricep bigger than a football and her forearm to Popeye width. An anchor tattoo rose up along the surface of her forearm as Tricia tensed her fist.

“You always did like girls with big biceps. Well what do you think about mine?”

The sound of an explosion echoed across the neighborhood as waves of energy rushed out of Tricia’s all powerful bicep. Arnold squinted, but was shaking with anticipation at the same time. As Tricia brought her forearm up, a large, mountainous bicep ground forward with the picture of a nuclear bomb hitting an island. A flash of light followed and as the mushroom cloud formed, her bicep rose higher and higher. And higher and higher! Muscle fibers raced to the surface, pressing against thin, perfect indestructible skin as her bicep climbed to three feet high! Arnold’s erection pounded along with it and as the waves of power subsided and the mushroom cloud dissipated, he let loose a load, soiling his pants. Tricia laughed again.

“Ha-ha-ha! Is that BIG enough for you Arnold? I’ll bet you’d just looooove to touch this super powered, spinach fueled muscle wouldn’t you?”

As Arnold sat up, he reached out like a zombie, enthralled with the thought. But as he drew closer, Tricia chuckled and with a quick puff of breath knocked him backward, head over heals. She released her flex and her bicep returned to the previous huge, but super sexy size she started with.

“Well you can forget it! In fact, just my very presents turns you on doesn’t it? Just look at your pants. Well if that’s the case, it’s time for me to leave. I believe Lila and I need to find out who the queen bitch of this planet is! Good bye Arnold!”

Bending her knees, Tricia leapt into the air and with a sonic boom, flew out of sight.

Sighing deeply, Arnold struggled to his feet and wandered home. His younger sister Jane was sitting on the front stairs sucking on a fudge sickle. Arnold let out a disgusted sigh, rolling his eyes at the sight of his short, pudgy, acne faced sister. Just turning 16 she had been begging Arnold to drive with her, but he had avoided all of her attempts. Jane was always overprotective of Arnold, even though she was younger than he was. This drove him crazy. He had to put locks on his doors and even changed classes at school to avoid her. But after what had happened today he didn’t care as he plopped down next to her on the stairs and buried his head into his hands.

Jane looked over at him, surprised he would sit next to her, but thrilled that he did.

“Arnold. What is going on today? You look terrible. Is there anything I can do to help?”

Arnold sat back, looking out across the street. Normally he would tell her to get lost. But he was so frustrated and confused he started talking, staring straight ahead the whole time. He explained the first gun, how he had made his dream girl Katie bigger and all she did was hurt him. How he made Amanda bigger (not mentioning the shrinking part) and how she had hurt him. How he made Lila super powered with his second gun and how she ridiculed him and how he even made his friend Tricia super powered and how she turned on him. Once he stopped, an uncomfortable silence followed until Jane stood up and turned toward him.

“Arnold! All of that is unbelievable. And terrible. You deserve better than that.”

Arnold looked up, his annoyance at even the presence of his younger sister returning. He shook his head. Her tan tank top was too small, with her belly fat sticking out over her silly red biker shorts. Her chunky arms and legs wiggled as she shifted back and forth on her yellow thongs. He turned away from her.

“No. There’s nothing you can do. There’s nothing I WANT you to do!”

Jane sighed deeply as she shook her long dark stringy hair. But then her mood changed.

“I know! Why don’t you make ME as powerful as those other girls! Oh! Even more so! As powerful as all of them COMBINED! Then I could protect you from them! I could finally protect you from everyone who wants to hurt you!”

Arnold looked up, his eyes flashing anger. “NO! Don’t you dare say that! Don’t you dare make me even THINK that!”

Jane ignored him. “But Arnold! Now is the opportunity I’ve been waiting for! To finally do what I’ve always wanted! And now you can help me! I love you Arnold! And I’ll always protect you from harm! Make me strong Arnold! Make me super strong! Give me the same muscles! The same strength! The same beauty! Then give me more! Make me stronger! Bigger! More powerful! More powerful than any of them! More powerful than ALL of them! Then you’ll want to stay with me! To never leave me! You can watch me beat up all of those bullies who treated you badly! To flex my rock hard, bulging, giant super muscles so you can caress them. So you can feel the mighty muscles of your protector! Do it Arnold! Do it!”

Arnold had his hands pressed against his ears. He rocked back and forth spurting out “No! No! No!” But just like before as hard as tried to NOT want it, the stronger the will for it to happen rose within him. The thought of his sister becoming as strong as Katie and as strong as Amanda, and as strong as Lila and as strong as Tricia filled his head. But not just AS strong, but stronger. As strong all of them put together! Stronger than all of them put together! As powerful as the Silver Surfer! As mighty as Thor! As beautiful as Aphrodite! And with the feeling of a punch to the gut, Arnold sat up straight with his eyes wide open, looking ahead at his gleeful sister.

“Yes! Yes! Yes! You’re doing it Arnold! You’re doing ALL of it! I can already FEEL the power filling my body, making me stronger, bigger and super! Don’t stop Arnold! Give me it ALL! Make me your Mega Sister!”

Arnold looked on, ready to cry. He didn’t want this. He didn’t want this most of all. But Jane did and now she was receiving everything he could imagine. As her body took on a heavenly glow, her fat slowly receded, causing her clothes to pull back, but only for a moment. As soon as the fat was gone, the muscles started to build. Big muscles, super muscles, goddess muscles. Smiling, Jane placed her right leg forward and tensed, causing waves of ultra dense muscles to rush to the surface, shredding her shorts with one horrible rip and flexing up Hulk sized quads pounding with unthinkable power. Giggling, Jane stood upright and placing her arms to the side, tensed her torso, tearing off her top and bra with one quick inhale, pushing forth huge, curvy, sexy muscles across her upper body. Her lats pressed out barn door wide bristling down to a narrow, muscle filled midsection that Jane rolled back and forth, shooting off sparks of power with each contraction. She tensed her chest and pectorals to put Superman to shame blasted forth, pulsing across her chest in waves. Her naked, perfect breasts meshed with her chest, becoming harder than any known substance and her excited nipples pressed forward, becoming even harder as they burned white hot!

Arnold sat back, fighting his own thoughts as Jane’s glow brightened with more power filling the sexiest body he had seen yet. Why did it have to be on his sister? Anyone but her! As she smiled down on him, her teeth became perfectly straight and white, her lips turned ruby red, her acne disappeared and her cheek bones rose up. Her dark hair now shined with health and flowed around her head like a super model. And the more he looked at her, the more beautiful she became. Within moments he realized she looked like Lynda Carter. Jane’s eyes even turned blue! Jane was becoming his true dream girl! Ah! Not that! Anything but THAT! Jane let out a satisfying moan as more and more power continued to pore into her body.

“Yes Arnold! Make me stronger! Make me bigger! Make me your dream girl so you’ll never ever leave me! I’ll take care of you! I won’t let anyone hurt you ever again! Make me your Wonder Woman, your Supergirl, your She-Hulk, your Power Girl! Only much, much stronger! Much more powerful!”

Arnold groaned. No! No more! Why did he ever let her read his comics! As the glow of power continued to build, Jane pulled up her arms up and winking at her terrified, weakening big brother, ignoring his pleas. With the sound and lightshow of a fireworks production, Jane tensed her arms and twin boulder biceps boomed into prominence and rose steadily up her forearm until the peaks reached the top of her fists. At this point, every muscle on her body was pumped to a ridiculous degree, flowing sexily around her body like the goddess she was becoming. Her naked, beautiful skin radiating with power and vigor. Against every fiber of his being, he was becoming hard again, further driving his desire to stop this, but only increasing the power of his sister’s transformation. Licking her lips, she gave him a knee weakening smile.

“Make me your Mary Marvel, Arnold! Give me the strength of the gods! Make me MORE powerful than all of them! Let me say the word!”

Arnold yelped. No! He couldn’t! The abilities of the entire Marvel family! The power of Galactus! The strength of the Greek Gods! The might of Darkseid! Sweat pored down his face. Fear gripped his entire body. He shook with disgust and desire. Not her! Not his sister! But as he gulped his next breath, he already knew it was too late. He could already see the knowing twinkle in his sister’s eyes. And with that knowledge, she pressed her lips together.

“SHAZAM!”

And with that one word a massive cloud of energy built up above them both, blotting out the sun! Jane reached up high and huge electrical sparks snapped and crackled with the intensity of a wicked lightning storm across her finger tips! And as Jane looked over at her cowering brother, she pulled her arms down quickly, allowing wave after wave of lightning to blast through her body! An entire electric storm unleashed a full fury of power around Jane and Arnold as a rainbow of energy pored into Jane. Arnold watched as his sister grew taller, pushing up to 6 feet tall and adding more and more muscles along the way! Muscles that could crush mountains grew stronger. Muscles that could destroy planets pulsed with increasing power! Arnold’s breath quickened as the energy continued to rush into his smiling, ultra powerful sister. The strength of the Greek Gods slammed into Jane’s body, the nearly limitless might of Galactus roared into Jane’s muscles, the unimaginable power of the New Gods blasted into every atom of her being!

And with one final thunderclap and a blast of ozone, the last of the energy cloud pulled into Jane as she now floated a foot off the ground. Slowly allowing her body to touch the earth, Jane giggled at her shocked brother.

“You did it! Every power of every hero and villain I could imagine, heck, every power of every hero and villain YOU could imagine is now mine! I could spin this entire planet on my finger like a basketball! I could crush the sun with my muscles without batting an eye! You really have made me all powerful! Thank you, thank you, thank you!”

Moving closer, Jane gently pulled Arnold to his feet as he quivered before her. Looking at him as though he were a small child, Jane moved right next to Arnold, allowing her body to touch his.

“It’s OK Arnold. Reach out and feel the muscles of the most powerful being in existence! Your ultimate protector! Your sister! Your goddess! I’ll never leave you Arnold. And I’ll never let anyone hurt you ever again!”

As Jane flexed up her bicep, the power of every man on earth radiated outward. Arnold shook his head as he watched the most perfect bicep ever flexed crunch up over his sister’s head. His hand trembled as he looked into her deep blue eyes and shivered as he reached up to touch the peak of the last person on earth he wanted to have muscles like this. He knew he was trapped. Jane really wouldn’t give him a moment alone now. And with her power, she really could be with him every waking and sleeping second. Touching the top of the giant, pulsing bicep, he squeezed and caressed the muscle, sobbing inside.

He had created the perfect dream girl. One who would never leave him. And one he could never be with. Releasing her flex, Jane stepped back, her beauty so enthralling that Arnold barely paid attention to her ultra sexy voice.

“Now Arnold, once I take care of Lila and Tricia we can finally be together forever! I can’t wait for you to see me protect you with all of the powers you gave me! Now don’t move, I’ll be right back!”
