I usually inhale air to make my burps, but it doesn't work so well on an empty stomach. So this time I decided to see what guzzling a litre of soda could do. It resulted in smaller, bubblier gurgles and burps that are a bit breathy. Once my stomach is full I open my throat and inhale. My collar bones pop out, my chest puffs up, and I let out some longer, louder, deeper belches until my tummy starts getting too grumbly. 1920x1080 HD
