As Meg swallows the formula an audible “gulp” is heard. She licks her lips and smirks as she grabs her boobs and moans. Another growth wave goes through her body.
Her ass started expanding outward, crushing the house below her, as her towering form goes higher and higher into the sky reaching 60, 70, 80 and finally a 100 feet in height. The giant pre-teen giggles, each giggle can be heard hundreds of feet away from their source. Joe tried to plug his ears, but to no avail, they started to lightly bleed.
Finally, Meg stopped giggling, her massive tits the size of hot air balloons, her ass completely crushed the house, yet Erin managed to survive, now staring at Meg-Zilla from a safe distance, worryingly looking at Joe, who hangs limply in his sister’s massive fist.
Meg looks at Joe, a lusty look in her eyes, she puts him down on her boob and attracts his attention by turning his head with a finger.
‘JOEY? I WANT TO GROW EVEN BIGGER, DO YOU HAVE ANY MORE OF THAT GROWTH JUICE?’ she asks. Joe covers his ears and when his kid sister stops talking, violently shakes his head, ‘No, Meg! I don’t have any more growth formula! And I sure as heck wouldn’t give it to you, you’re massive already, what will mom do to me when she comes back?!!’
Megan sticks out her tongue and swats the air, ‘I DON’T HAVE FO LISTEN TO MOM ANYMORE, I’M A MEG-ZILLA NOW! AND NOW YOU HAVE TO LISTEN TO ME, SO MAKE ME SOME MORE OF THAT FORMULA!’
She slaps her boobs, causing them to wobble. Joe looses his footing and falls on his back, immediately sinking into the soft tit flesh.
After he struggles to get out of the fleshy trap he sighs with regret, why did he even decide on this project?! Of course something would go wrong! He rubs the bridge of his nose and, slowly, remembering that although the giant size he is still speaking to a literal seven-year-old, explains, ‘No Meg, I can’t do that, your ass flattened all of my lab equipment! I physically can’t produce more formula!’
But Meg won’t listen: ‘LIAR! OF COURSE YOU CAN! YOU JUST DON’T WANT YOUR LITTLE SISTER TO BECOME BIGGER THAN GINORMA GIRL!’ she yells out.
and now it’s your choice to pick:
A. Joe and Megan notice Erin, who is standing beside some equipment she managed to salvage from the basement, anticipating Meg’s growth spurt
B. Joe rebells against Meg, refusing to do her will (something unexpected happens)
