Vallery is so excited to try this special new soda she just got at the store. It's not just any regular old soda, this is a special magical soda that promised to help her rapidly gain weight. Vallery eagerly pops the top and starts chugging, but is disappointed when nothing happens. She takes a few more chugs and let's out a burp, and that's when things start to happen! Every time she burps her belly gets bigger and bigger right before your eyes! In no time, Vallery is massive thanks to the magical soda and her big burps!
