Watch me chug down a liter of fiji apple sparkling water while I inflate my belly soooo tight with my aquarium pump! I get so full, but I still finish the whole liter and let out some BIG burps and show off my tightly stretched belly button too. My tummy hurts so bad after inflating so much and chugging all that sparkling water, I moan and rub it to try and push out the burps... looks like I'll be round like a balloon for the rest of the day!
