Playing around with my mouth, using my lips, tongue, inner cheeks, uvula, esophagus and throat muscles to give the inside of my mouth a wave effect. Drinking plenty of water to keep my mouth moist causing esophagus bubbles and gentle burping. I like showing off my razor sharp straight teeth, sticking out my pointy tongue playfully and giving my lips a good licking. Lighting makes it clear to see all of the inside of my throat contracting as well as the outside trachea bobbing up and down.
