Joan was stamping through the forest, tree after tree being decimated by her mega muscular form. Towering over the majority of the treeline, most only really coming up to just over her knees, her massive breasts rose and sunk and jiggled with every step, her muscles swelling and pulsating with pure power as she carried on walking, native animals fleeing her form for miles around. The hungry muscle monster came to a clearing and much to her liking she found nothing other than a lake, even larger than the last, more fitting to accommodate her form. She smiled and flexed her biceps watching them swell and pump larger with hardly any effort, it was a miracle she could see past her huge tits at this point as they filled so much of her view. She stood admiring herself on the edge of the lake, feeling her muscles up and down and moaning with every touch of her large nipples, luckily for Cra, these moans helped her pinpoint Joan's location and much to her liking also, she smiled as she came across the lake, but unlike Joan, she took no time in hesitating to jump in, the water sweeping over her, she instantly started expanding and moaned insanely loud as her 30 foot form quaked and bulged all over, tits shuddering and jutting out foot by foot at a time, the water being absorbed up her crotch as she squealed at the feeling, her abs began to throw anatomy out the window and just pile more and more there, she was transforming all over, her body becoming unstable as muscles piled on top of muscle, row after row of abs were forming on her stomach as she cried out in blissful orgasm as she reached 40 feet, "IM BECOMING.. UNSTOPPABLE!" She cried out again, 50 feet, 60 feet, her body was undertaking a transformation much like Joan's where her shoulders and traps boomed way over her head, her arms now so large it was impossible to leave them directly by her side, 70 feet, 80 feet and still going, her breasts were no longer jutting out, they were straight up surging beyond all comprehension, her body overloading as she let out a guttural moan and cry, her head flying back into her still expanding bulk as it grew and grew like the rest of her. A few minutes later, despite the racket of moans and groans not 5 minutes ago, Joan snapped out of her power filled trance to see Cra! over 170 feet tall, her humongous tits right in Joan's face, it took all of her restraint to not lean forward and bite on one, although it wouldnt have mattered anyways as she felt the ground rumble beneath her, the tits that were roughly half the size of her began to rumble followed by "MMMMHMMMM YEAH!" And then it happened, Cra bulged in every direction gaining impossible levels of muscle and titflesh, "OH GOD, NO WONDER YOU LOVED THIS SO MUCH!! *Swell bulge pop expand sweeEEEEEELLLLlllllll* YESSSS!!" Hissed Cra as she reached 200 feet, she was now only knee deep in the lake, her muscles rumbling and bulging, rising way over her head, growing so big so fast she couldnt help but orgasm as her clit pulsed with untold and relentless energy, Joan, stupidly, tried attacking the colossal Cra by doing what was the most stupid thing to do in that situation, she reared back and let a full force punch hit Cra straight in her clitoris, it pulsed and swelled for a few seconds and the moaning stopped, Joan looked up at the towering behemoth wondering if it worked, but what she couldnt see was Cra's face, mouth wide open but clearly smiling, her entire body then trembled intensely, more and more until she fell, straight down onto her back, no longer in the lake. The silence continued for a few more seconds until "FUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU" *BOOM!! BULGE!! SWEEEEEELLLLLL!!* "MY GGGGGGGOOOOOODDDDDDDDDDDDDD!!!" Her body rocketed in every direction, 250 feet, 300 feet, 350 feet, cum jetted out of her like a firehose, a shotgun like spray covering the forest for miles on end Joan was smothered underbutt before she could even blink the expansion was so fast, Cra came and came and grew and grew, her muscles going on a seemingly endless surge, her arms and legs bulging with such immensity, leveling every part of the forest they bulged and grew into, she screamed as her surge slowly came to an end at 500 feet, her tits had zero sag and were sticking at least 300 feet into the air by now, her nipples adding another 50 to that as they spat out the magical lake water, coming back down and soaking her tits, adding more to her obscene growth, she sat up and reveled in the feeling of nothing but pure pleasure and power, the pure rush of infinite ecstasy running through her river like veins, "HO.. HOLY SHIT, THE POWER!! I FEEL LIKE A GOD, LOOK AT ME! THIS SIZE! THESE MUSCLES! THESE TITS!! IM HUGE, M..M..MUST G..GET BIGGER! OHHHH!!" She cried out, the power had really changed hands this time, but what she didnt know is that her body had transformed from the intake of so much magical lake water that she was basically a living factory of the stuff, she grapsed what she could of her huge tits at least 250 feet in circumference with her tiny house sized hands, squeezing and moaning as water jetted out of her nipples. But who or what did it hit? if anything.
