She suddenly staggered from a sudden weight behind her. She turned and saw her rear was swelling to triple it's original size. She dropped the script she was holding and stared at her rear. Her eyes refused to look anywhere else, ignoring the fact that her breasts were starting to become bigger, ignoring the fact that the space between her top and pants were starting to become wider and wider, revealing a rather large blue belly. She luckily snapped out of her trance just in time to realize that her clothes were becoming way too tight as her body continued to swell bigger and bigger; she had to get out of them.
