Nothing... absolutely nothing. Mary laughed it off, expecting some sort of extreme transformation where she would blow up like a balloon, bursting out of her clothes. So she laughed and went into the kitchen to make herself a snack. She grabbed a giant can of cream and just cracked it open and chugged the whole thing down with reckless abandon. After finishing the can, she took a deep breath and burped extremely loud, patting her swollen stomach after. She still felt hungry so she just began breaking containers and bags open and shoving them into her mouth. It seemed so natural to her that she didn’t even question it. After cleaning out her pantry, Mary easily weighed over 250 lbs. She looked a lot closer to the vial picture, but she wasn’t quite there yet, and she was still hungry. Shifting over to the fridge, she then opened it up and began her second round of feasting. This time, her clothes tore to shreds, not being able to contain Mary’s new girth. She only paused eating to burp or fart, clearing more space to stuff herself. After clearing out the fridge, her stomach was finally sated. She looked down and saw the destroyed clothes she was wearing earlier and attempted to reach for them, but gave up after one attempt. She then waddled over to the couch and turned in the TV. She figured she was easily 450lbs and rubbed her massive belly. She then decided to feel over the rest of her body. Her tits had exploded from her normal Cs to GGGs maybe even Hs. Her ass (though flattened by the couch) could easily fill an entire couch by herself. Her thighs were massive and her arms were like flabby wings. She felt like she could stay there a long time...
