she tried to stretch but her fabric struggled against the expanding curve 
the sensation was intense a pulsating beat deep within her expanding glutes 
soon the entire room seemed to shrink as her ass became immense taking up every available inch 
her daughter Violet watched in amazement and shock as her mothers behind turned gigantic 
then Violet felt it too a similar warmth spreading through her own posterior regions 
her school uniform stretched to its limits as her butt swelled rapidly a delightful pressure 
now both Elastigirl and Violet possessed unbelievably huge butts a sight to behold and adore 
the expansion continued an unstoppable wave of flesh and curves 
their figures reshaped into a monument to bigness a sensuous exhibition 
soon the family home was barely able to contain their glorious bottoms a truly awe inspiring view 
the air was thick with the scent of taut material and lustful anticipation 
the Parr family now boasted the biggest butts in the city a reason for pleasure 
every movement caused a sensuous ripple through their enormous cheeks 
a chorus of curves a tantalizing display for all to see and admire 
they knew this was their new reality a curvy life filled with expanding pleasure 
Elastigirl and Violet embraced their new forms cherishing every curve 
they continued to save the day but now with extra bounce and magnificent flair 
a legendary sight of female power and super sized butts 
the world would never be the same after the helen parr ass transformation a truly memorable happening
