I just got a soda stream because I am addicted to carbonated water...but I had an idea. What if I carbonate the water three times to recommended amount? I get the water super bubbly, pull my tits out, and start chugging it. My belly gets huge and bloated as I swell and start to get gassy. I burp hard, lots of rumbling deep juicy burps, pausing to chug and make my stomach distend as I push on my sternum and pat my chest, shaking loose lots of burps! I even have to pull my belly out of my shorts to make room... I love fizzy water burping!
