Tossing a quick glance at the basketball players, Amanda turned and slowly walked toward the weight area, allowing the groups to pick their spots. After a few moments of being ignored by everyone as usual, she gravitated toward the largest boys as they set up the bench press and were ready to start a contest. Looking around, nobody was paying any attention to her as she moved in closer. The weight was already up to 300 pounds and only a few boys were still in competition. Samantha was fawning over Jake, who had just finished pressing the weight. This was her chance. Walking toward the bench she looked right at Jake and Samantha.

“Mind if I give this a try?”

Everyone paying attention laughed. Other heads turned to see what was so funny.

Jake pointed at her. “You? Amanda, you couldn’t bench press this bar, much less 300 pounds. Are you on Meth?”

Samantha smiled too, but gave Amanda a quizzical look next as the last time she saw Amanda, she was much smaller. Amanda simply smiled back at both of them and stood next to the bench.

“Well there’s no harm in trying, now is there. But before I do, has everyone seen the Incredible Hulk movies?”

The large group all nodded, wondering what she was talking about. Smiling at their confusion, Amanda made sure all eyes were on her.

“Then you’ll recognize this!”

Amanda thought about the Incredible Hulk. How a small man turned into a huge muscle beast. Only Amanda also thought about keeping her female curves to go along with bigger muscles. And not only that, but she thought about increasing her strength too.

And just like that, Amanda’s muscles began to expand. Her exposed legs slowly pressed forward thicker quads and bigger calves until she sported the legs of the best sprinters in school. Her upper body pressed bigger with wider lats, a thicker chest and bigger boobs, pulling her shirt up to expose a killer six pack. Her shoulders pressed out too as Amanda pulled her expanding arms out and purposefully brought them up into a double bicep pose.

“Or maybe I should have said a female version of the Hulk! Bigger muscles on a female frame.”

The crowd started gasping and murmuring as Amanda’s muscles continued to expand and her shirt started groaning. Winking at Jake, Amanda flexed her arms and those baseball biceps blossomed forth and quickly loomed bigger. Amanda thought about her muscles becoming super strong, and just like that her body crystallized with the hardness of a top level female bodybuilder as striations rippled across her frame. Amanda giggled as the shot of strength tickled her body and her biceps surged up to the size of softballs. And as more people began to stare at Amanda, she flexed her biceps harder and they surged forward with deep splits, detailed muscle fibers, large pulsing veins and twin throbbing peaks. Once she was satisfied with the slack jaws of her on lookers, Amanda released her flex and sat down at the bench, reaching up to grab the bar before the stunned crowd.

“Now that I have your attention, let’s see just how strong these muscles really are!”

Licking her lips, Amanda pulled the 300 pound weight off the rack and chuckled at how light it felt.

“You call this a heavy weight? Are you sure these aren’t just painted Styrofoam disks?”

Amanda pulled the bar down to her chest as her athletic bra and top rose up higher and tighter against her surging pectorals and C sized boobs. Rubbing the bar against her breasts for a moment, the pressure caused her to moan. Not with pain, but with pleasure. She let out a happy sigh. A 300 pound weight felt like a light squeeze, barely compressing her breasts! Just how strong and powerful was she already?

As the crowd looked on, Amanda pressed the bar up quickly and with a short pause for effect, cranked out 10 quick repetitions before racking the weight. Sitting up quickly, Amanda pulled her arms back, making sure to press her chest out. Her boobs pushed forward incredibly, seemingly defying gravity as her nipples tented through the athletic bra and the t-shirt so hard that a line formed between them. With a final stretch, the threads on the side of the shirt began to grown as her muscles rippled and surged.

“How’s that for a start Jake? Care to add more weight?”

Glancing to the side, Amanda saw a list of the best lifts and noticed it was at 520 pounds.

“Why don’t you double the weight? A 600 pound bench press would beat the school record!”

The other boys looked over toward Jake who was both stunned and to his surprise, turned on. Samantha noticed this and frowned, not liking where this was going. She pointed to the boys.

“So little miss ‘I grew bigger’ thinks she’s that strong? Why not see just how strong she is! Put on 1200 pounds!”

Looking back at Amanda with daggers, she spat. “Unless you’re afraid?”

Amanda smiled coolly. This was great! She was shocking Jake, maybe even turning him on in the process, and pissing off Samantha too. Amanda looked around, trying to maintain her own composure. She would have liked to try out her new found powers on her own before seeing how they worked and what her limits were. But sensing she could tackle anything thrown at her, Amanda simply nodded.

“Sure thing. You thought it was pretty funny when I was shrinking. Let’s see if you’re laughing when I grow bigger. And stronger!”

Jake stammered a reply. “But that’s more than the world record. For men! A lot more!” But then Jake stopped. What if Amanda could do that? His breath shortened and his body tingled. Could Amanda really become some type of She Hulk? Those tits looked awesome! And those muscles were actually a turn on! He blinked, never having made that connection. Sure he liked the athletic girls. Samantha had a hard little body shaped by tumbling and such, but he had never envisioned a girl growing so strong or so, so… Muscular! What if Amanda really did grow into a She-Hulk! What if she did become super strong and muscular?

Lost in thought, Jake didn’t realize that all eyes were on him. And Jake’s bug eyed look forced Samantha’s frown even deeper. The rest of boys waited for his next statement while Amanda’s smile grew wider. Blinking, Jake looked over at Samantha and forced a smile. “Uh, sure, whatever Samantha says.”

Samantha snorted and walked over to the other boys, pointing to the weights. Jake continued to stare at Amanda who brought her arm up to brush the long dark hair off her shoulder. Pausing for effect, Amanda peered over at her bicep and back toward Jake with all the sexiness she could muster. Amanda began to tense and un-tense her bicep for Jake, infusing more mass and more strength into her arm with each tense. The 16 inch softball sized muscle pressed outward, pushing the sleeve of her shirt back toward her shoulder as the peak crept up her forearm. The massive 16 inch bicep slowly pushed toward 17 inches of muscle perfection. Amanda locked eyes with Jake who was seemingly going catatonic with her display. She glanced down and noticed Jake was building an erection as she flexed her bicep. She really was turning him on! How awesome was that! First she’ll make Samantha jealous, then she’ll drive Jake to some kind of muscle lust, then she’ll crush them both! This will be so great!

As the last weight was clanged onto the bar and the screws tightened to the holders, Amanda gave one last bicep squeeze, pressing out a bicep bigger than any woman her size could hope to flex! An 18 ball of wonder consolidated on her thin frame, looking damn scary to Samantha and near perfect to Jake!

Releasing her flex, Amanda laid down on the bench and reached up to the bar. By this time most of the gym was gathering around to see what was going on. Was that Amanda? Were those muscles real? Was she really going to try and bench press that much weight?

As Amanda gripped the bar, she thought about Hercules from her literacy class, about the strongest man competitions she had seen on ESPN, and the most muscular woman she had ever seen on the internet. And thought about putting them all to shame. And with the power of the gun fully at her disposal, her body reacted quickly as her strength multiplied and her muscles expanded. With a soft giggle, Amanda pulled the bar off the rack and held it for a moment as the crowd drew closer. Her legs expanded with raw, male bodybuilder sized muscles, pushing her socks down to her ankles with melon sized calves and 12 inch thick quads. As her upper body expanded, her back widened dramatically, tearing her t-shirt up the sides and pulling it up toward her expanding chest, exposing an incredible array of abdominal muscles that writhed beneath seemingly thinning skin and multiply into steel blocks that even began working their way up her sides.

Nearly laughing, Amanda slowly pulled the bar down to her growing chest, reveling in her strength and size. She could no longer see her stomach as her boobs were now out passed D cups and were tearing up not just the t-shirt but the stretchable athletic bra beneath. Steel hard pectorals rose in concert with her breasts as the bar pressed down, sending another lightning bolt of pleasure into her body. Allowing the weight to settle on her breasts, the bar pushed down into her boobs to her pectorals and stopped. Looking straight up Amanda imagined her boobs becoming filled with muscle. Becoming rock hard. Becoming steel hard. And within moments, the bar began to rise upward. Not from her arms, but from her breasts. Releasing her grip on the bar, she simply cupped the bar in her hand to keep it from rolling off her chest and within seconds the bar was resting against her engorged diamond hard nipples! The 1200 pounds weight was no longer capable of even denting the softest part of her body!

And with a soft, pleasurable sigh, Amanda re-gripped the bar and pressed it upward until her arms locked, causing those watching to let out gasps of disbelief. Was that real? Was this just a show? Jake erection was now pressing painfully forward. Samantha’s rage was turning toward shock. And Amanda’s shirt ripped further up the sides as she pulled the bar back down and pressed it back up quickly.

Amanda giggled. “Yeah, Hercules. That ought to do. For a start!”

Pressing the huge weight a few more times, Amanda racked the bar with a deafening clang. She sat up and looked around at the large crowd now surrounding her and then back at Samantha and Jake. Smiling, she weighed her options.
