Maude, Mabel and Elizabeth have been working at the local snack cake factory for the summer. The company, as such companys often are, was very generous with their product and there was often plates of free snack cake in the canteen or free boxes of slightly imperfect snack cake for the taking . The girls had not wanted to overindulge but as the weeks passed they found they simply couldn't continue to resist the the call of all that spongy creamy goodness. All three of them ended up devouring countless extra-high calorie treats. By the end of the summer they had gained a LOT of weight.
Maude and Mabels' figures are quite ruined. 

However, to  Maude and Mabel's distinct vexation, while their cousin Elizabeth ate twice as many cakes as either of them, her body has stored the extra pounds in a rather different manner.

Alternative story:
The identical triplets had all discussed trying to join the Sisters of Feminine power but only Catherine had actually gone through with it. Clarabell and Clare had thought that the idea of psychically-powered breasts was just too weird.
 After months serving the Sisters Catherine had passed the Sister's Test of Nobility and been activated. 
Six months went by and Catherine's IQ got higher and higher, her big belly shrank into a slender flat tummy, her hair turned blonde and wavy, her plump limbs became slender and beautiful, she developed telekinesis, telepathy, and matter manipulation, her flabby butt became something so tight you could bounce a quarter off it, her piggy-nosed mug developed into somethinglike the face of a particuarily cute angel, she gained strength and agilty that meant that with High Phase Delta Energy levitating/controlling her breasts she could perfomed olympic level feats of gymnastics and...
her formally flat chest expanded and firmed and developed and improved and swelled and enlarged and waxed and bolstered and widened and bloomed and GREW until it had reached a truly Ludicrous size.
She also had a cute boyfriend... or six.
The other two stubbornly refused to admit they had been wrong but standing at the bus stop looking at their sister's incredible body they began to feel it was time to give in and see if they could join the sisters as well.
Of course what bugged them even more was knowing that Catherine was *still* growing and even if they got activated tomorrow their formally identical triplet would always be (much) bigger.
