Stacey held the glass up to her face and looked back at Stephanie as if to ask if she could, Stephanie knew that her mother would definitely have more energy drink for her, she wouldnt have just brought one bottle of the stuff,
"Uh yeah sure, go ahead, my mother will have more of the stuff for sure" Said Stephanie,
"Awesome, thanks girl!" Replied Stacey,
Angela still outside of the door overheard her daughter give up the drink and burst through the doors,
"NO STOP!" She shouted,
But it was too late, Stacey had already downed the drink and her breasts had started visibly rumbling, making her elicit a long low level moan,
"Mmmmmm oooooo yeahhhhh.. Y-you really thought i'd forgotten? Oh god yes! *bulge, grow, expand* And t-to t-t-think that a small bottle had m-made ohhhhhhhhh made me this? Fuck knows how.. *buuuugle, growww, expaaand* How huge i'll be now!"
Her entire body was now visibly rumbling, her breasts and muscles shuddering and expanding all over, was she holding it back? Her growth was downright explosive last time, she had made 12 feet tall, her muscles slowly enlarging even further, when all of a sudden her body detonated to 15 feet tall, her muscles erupted with size and power, she began looming even further over the other two as they began backing out of her room, Stacey moaned again as the floor beneath her groaned in pain,
"IM GOING TO OUT G-GROW THIS WHOLE MANSION, OHHH YES! WATCH MY MUSCLES GROWWWW OH GOD!" She screamed,
Angela grabbed her daughters arm and they began running downstairs, Stacey trying to follow but was stopped even bent down by her massive frame taking up the whole doorway and more, she felt the floor groan and creak below her as the pleasure racked up, she threw her head back and lay down on the floor, she couldnt hold back any longer, she felt so powerful and needed her body to match,
"OH FUCKING SHIT YEAH!" She screamed as her entire form detonated to 20 feet tall, her body reached 3 tons in weight and that was all the floor could take, she smashed through it sa she continued to bulge over and over, muscles detonating massively all over, her body nearly wider than it was tall,
"YESSSSSSS OH FUCK THE POWER! *b-b-buuuulge CRASH growwwww* DING DING BOTTOM FLOOR, OHHHHHHH!" Stacey cried out again, 25 feet tall she smashed down to the bottom floor, standing up she crashed back through to the second, flexing both her arms she roared as she let her body grow and expand to 30 feet tall, she hunched over and crouched as her body carried on widening and filling out, each bicep weighing in at 2 tons each, her 16 ton body nigh unstoppable by this point
Meanwhile Angela and Steph had ran to the kitchen, her mother frantically pulling her over to the large jug still full with 9 and a half pints worth of formula, she grabbed two glasses from the cupboard and dunked them in, handing a full glass to her daughter,
"Drink up Steph, hurry for fuck sake!" She said, but it was too late, Stacey smashed through the nearest wall her huge muscular arm bigger than a family SUV had come through the wall,
"PEEK A BOO YOU FUCKS, GIVE ME THAT!" She shouted, smacking the two across the room with a flick of the wrist, grabbing the jug out of pure instinct and bringing it back to her, the house fell silent for a moment, as Steph and her mother looked up at the wall. A huge pair of tits then burst through, brick and debris flying everywhere, orgasms quickly followed as muscle erupted through the wall, tearing the mansion apart with her huge 40 foot form,
"O.. OH... OH-OHHHHHH MY GGGGOOODDDDD!! S.. SO F-FUCKING HUUUUUGE! BIGGER AND BIGGER, OUTGROW EVERYTHING! MORE!" Stacey screamed. she screamed as her pussy gushed and unfathomable amount of cum, her rapid explosive growth couldnt be suppressed anymore, she let control of her body go and let the growth take over, her mouth agape, eyes wide as tens of tons of mass poured on in, never stopping, not even for a second, as her body blew out with muscle and size over ad over, as her tits outgrew entire houses, as her godly muscles outpaced the growth of her body, she let thoughts of using skyscrapers as dildo's and volcanoes as vibrators flood her mind, and that was just scraping the surface of her dark mind, completely warped by the 130 tons of hyper muscle she had become, her face buried indefinitely by her bulk, her growth shot up even faster 110 feet and she burst out of the roof of the mansion, her body tearing up the rest of it as she bulged and widened even further, she led down again, wantint to make good on her promise, she let herself orgasm and squirt all over the grounds, roaring as her body pulsed and bucked and writhed in pleasure, more and more power flooding her already supermassive frame, her boobs shot up and out, shooting straight out in to the sky, nipples larger than buses at this point, 240 feet tall and she was crashing through the last remnants of the mansion, finally destroying it all as she topped out at 270 feet tall, her body still rumbling in excess,
"I T-TOLD YOU I'D OUTGROW IT ALL, HAAAHHHHHHHHH YESSSSSS!! I CANT EVEN IMAGINE HOW MUCH POWER I WIELD BY THIS POINT, BODYBUILDER GONE GODDESS AAAHAHAHA! FUCK IM SO HORNY, SO POWERFUL! ALL I WANT IS MORE, TO BE SATISFIED, UGGHHHHH FUCK.."
Stacey stood at full height, her colossal frame blottted out the sun over the mansion grounds, she turned her massive form around and gazed at the city behind her, opening her arms to it as if to imagine crushing it all against her tits, as she took step after step after step towards it.
Angela and Steph were lucky to be alive, buried under a small amount of rubble the two dug themelves out and watched Stacey wander off, her huge fat ass jiggling with every step, coughing and spluttering Steph turned around to see her mother trying to pull something out of the rubble, a black box of some kind, the kitchen safe! Steph wandered over and tried to help but both of them were rather physically lacking, but after a good few pulls the safe was out, the door was busted inwards but still opened fine to her relief, to reveal the two canisters of the formula, Angela took them out and held them in her arms. Countless police, fire and national guard trucks and cars pulled up to the scene, officers instantly took the canisters and shuffled the two in to a car for questioning back at the station, if it was still there, all on Angela's mind was, what would become of the canisters?
