Janie, even though she was not sure what happened broke away from her sisters grip and bolted back into the change room. The door slammed and locked behind her.
The room had done this too her in theory it should reverse it.
She took a deep breath then unlocked the door and went back out.
There was a flash of light as her eyes adjust to the sunlight outside..
She smiled as she was no longer crotch level with her little sister. Suzy was still taller than her but at least she could look her in the face.
'Looks like i'm the big sister again.' she told Suzy
Suzy Started to laugh. 'I won't argue with you there BIG sis.'
Janie's Face turned beet red. Something wasn't right.
Janie looked down at her body, and tried to scream but nothing came out. This wasn't her body. she was at least 250+ pounds.
Her tiny bikini was almost invisible in her large rolls of fat.
