I was commissioned to use my burping talent and make a 20 minute video of me drinking a 2 liter and burp. I guzzle the liquid down and let the burps come out. A little at first, but once my tummy is full of bubbles, I can't stop the burps from coming out. More and more I burp and release the pressure from my tummy. I continue drinking the soda and filling up my tummy to continue burping until the 20 minutes are up. If you enjoy a variety of burping, this is for you. Small burps, big burps, one right after the other.
