Bet's mom's torso started to spread out.
As it did, she grew two extra heads which rested on her, now their, shoulders.
Her sisters looked exactly like her, too.
She grew two more pairs of arms and had 6.
She grew an extra pair of legs to compensate for her torso. One on each side of her, to give her 4.
She also had three breasts, about D cup.
Her clothes modified, too. She had a larger shirt, with three neck holes and 6 arm sleeves. Bet's mom, now moms, also had a pair of modiefied jeans with 4 pant legs.
"Mom" Bet said in fear "what happened to you?"
