Superman took a few steps back, attempting to size up the situation. He had already proven to this girl that he was stronger, but now she was back and looked more powerful, more muscular and more confident than before. All of these facts were playing havoc on his thought process. Could she really have become stronger than before? And just how was she doing it? But worse yet, her naked, glistening, hyper muscular body, womanly curves and beautiful features were sending his normally controlled lust to the forefront. As he finally stopped stepping away from her, he set himself while his manhood continued to rise.

Amanda smiled knowingly. She felt incomparable power pump into her inflated, indestructible muscles. Power so evident that she was causing Superman to back up with respect, fear and apparently attraction. The fact that her muscles were causing another male to get hard at just the sight of her body was immensely satisfying. Not only was she going to break Superman, she was going to drive him into a sexual frenzy at the same time.

Pulling her hands off her hips, Amanda raised her right arm up, causing her bicep to crunch forward into a perfectly detailed mountainous muscle that bulged bigger than Superman could ever hope to flex. Batting her eyes seductively, she brushed her shining brown hair over her dense shoulder and pulsed her chest gently, causing her pectorals to ripple and her breasts to bob. This simple movement also caused Superman to visibly sweat.

“Where are you going Superman? You’re not afraid of a little old teen-age girl are you?”

Superman cleared this throat. “Of course not.” He let out a sigh, pulling his manly chest out as best he could, trying to regain control of the situation, even though his own body continued to betray him. “Now young girl, I already asked you to stop these unnecessary acts of destruction. Yet you continue to damage city property. I am only going to ask you one more time to stop this and come with me.”

Amanda chuckled. “Oh, I can see that you’re about ready to come all by yourself.”

Superman flushed red as he was unable to reduce the quivering down below. He was becoming harder than he had ever been before and part of him didn’t want it to stop. Amanda brought her arm back down and clenched her fists, causing her muscles to inflate across her body into a mass of feminine power. Licking her lips and swaying her hips she pushed her lower lip into a mock pout.

“Awe. If you want me to stop Mr. Superman, you’re welcome to try. After all, you knocked me back pretty far just a few moments ago. Surely I couldn’t have become more powerful than you? Surely your big manly muscles are still stronger than my girl muscles. You’re still in charge around here.”

Amanda’s expression changed slightly, back to one of confidence. “But you’re going to have to prove it tough guy. Give me your best shot!”

Superman’s shoulders slumped slightly. He was hoping to avoid this.

“If that’s the way you want it.”

Pulling his arm back, he stepped forward. Amanda remained in her spot, letting out an excited sigh as Superman clenched his fist and delivered a full powered punch to her breathtakingly muscular abdominals with a deafening boom. The shock wave from the blow shook cars and buildings all around them once again. And just like a few minutes ago, the punch was followed by a yelp of pain and a grunt of disgust. Only this time it was a masculine voice doing the yelping and cursing.

Amanda tried not to laugh as Superman shook his damaged hand. The reversal of fortunes was both funny and arousing. She barely even felt the blow. Raising her eyebrows she winked at Superman.

“Gee Superman, was that your best punch? If you hope to subdue me with little love taps, you’re going to be sorely disappointed. Care to try again?”

Grumbling, but still turned on more than he could even comprehend, Superman pulled his other fist back and this time unleashed a punch with all of his Kryptonian might. A punch that would capsize a battleship sizzled forward. This time the concussion sent waves reverberating for blocks, blowing out more windows and sending cars smashing against buildings.

And as the blast dissipated, Superman stood stunned as Amanda had brought out her own hand and caught his fist, having absorbed his mightiest blow easily. Superman grunted again as his arm quivered and all of his muscles tensed.

“This. This is impossible. You can’t possibly be so. So…..”

Amanda smiled broadly. “What? Strong? Powerful? Hugely muscular? So a teen-age girl can’t possibly be as strong as the mighty Superman. Well too bad for you. It seems that I AM stronger than you now. My muscles are bigger than yours. And this killer body is driving you crazy.”

As Superman struggled, Amanda didn’t move an inch. Her strength now easily eclipsed Superman’s. This both frustrated him and drove him near orgasm. Amanda laughed at his struggles and the tent in his tights.

“Gee Superman, how does it feel to be so much weaker than a teen-age girl? Angry? Confused? Turned on?”

Superman looked with tears in his eyes as the young Mega girl seemed to read his thoughts. Reaching out with other hand to try and break the grip from this beautiful powerhouse, Superman groaned as Amanda began to squeeze his fist with her small hand, crunching bones. A wave of pain swept through his body and the minor squeeze from Amanda sent the Man of Steel down to one knee. Amanda continued to gloat, thoroughly enjoying her dominance over the strongest superhero of them all.

“Face it Superman. You’re hopelessly outclassed. Not only are my sexy muscles bigger than yours but they’re more powerful than your so called super muscles. I’m barely exerting any force and I’ve driven you to you knees. Now it’s your turn to stand down!”

Bringing her other arm back, Amanda pulled her hand into a fist and unleashed a punch into the middle of Superman’s big red S, smashing though his previously invulnerable muscles, crunching his chest and sending him rocketing away.

Amanda giggled with delight as Superman smashed through cars, buildings and anything else in his path, bouncing along the ground, flaying helplessly forward against the most powerful blow he had ever received.

Not willing to give him the chance to escape, Amanda tore after him, enjoying the sensation of super speed as the wind whipped through her hair, the air around her mighty muscles sizzled and the ground below her bare feet crumbled and ripped as she ran forward at blinding speed. A vapor trail of concrete and debris followed in her wake as she quickly caught up to Superman who had smashed through a building a mile away from where Amanda had punched him, finally skidding to a halt in a park, digging a trench into the soft ground.

Superman barely had a chance to regain his senses as Amanda slowed down to walk up next to him, her muscles crackling and sparking with inhuman power and strength. Superman tried to remain conscious as pain racked his entire body. He winced as every breath pushed his broken ribs into his lungs. He could heal quickly, but not fast enough to escape the stunning, insanely muscular girl standing over him. Even in terrible pain, he was turned on more than ever before. To be controlled by a beautiful, muscular woman was apparently more than he could emotionally handle. And to Amanda, her utter command of the situation was turning her on too. Bending over, she smiled at the beaten superhero.

“Well, well, well. It appears that I really AM the most powerful girl on earth. One punch and you’re finished, broken and barely awake. Good thing I only used a fraction of my strength isn’t it?”

Superman groaned with pain and shock. Was she really that much stronger than him now? Amanda chuckled.

“And now that I’m in control you won’t be lecturing me anytime soon, now will you? Of course, I’ll be lecturing you.”

Amanda looked Superman over and giggled. Even bloody, beaten and nearly unconscious, Superman was still sporting some serious wood. So he liked the fact that he was being dominated by a mega muscled Supergirl did he? Well why not just drive him over the edge?

Superman could barely reach up to touch his ear and send out an SOS as Amanda straddled the helpless hero over his midsection. Her naked, mega muscular body was primed back up to immense proportions crackling with incomparable strength and power. As her mighty muscles began to pulse and spark she looked down at the defeated Man of Steel.

“Now that I’ve subdued you Superman. Whatever shall I do next? Any ideas?”
