Shrunk at Daycare!

You plop into a thick, sticky liquid. The smell here is sour and stale, it smells both sweet and old. The stomach is still dry and empty, there is only liquid food and juice in it, but after 5 seconds you hear the noise of water, gastric acid began to ooze from the walls of the young stomach, which surely flowed down and increased the volume of the contents. You are floating on the surface of the lake, trying to find at least some platform in this fleshy prison in the dark, which may be your last place where you have been. Outside, you can still hear slurping and sucking, after which a sticky and sweet stream of liquid food falls on you, which drowns you down and the lake is already thickening, it's harder for you to row with your hands and come to the surface, but you were lucky to get a whole piece of food in your stomach, you barely swim out of the water and rise to a piece of food.
Trenton's stomach bulges out from under his T-shirt on the outside. You hear the glass being put on the table with the last sip, another stream of liquid is pouring on you, then Trenton starts to get off the chair, because the inside started shaking, the liquid splashed out, and you were knocked down, and your raft was twitching around, the stomach started. The stomach perked up, its walls shrank, bent. Trenton gets off the chair, he presses his hand to his stomach, you see the outline of the hand inside, and then everything starts to boil inside, shake, Trenton feels the pressure growing inside, and then...

Trenton makes a nice, sweet burp. At this point, can you grab the wind and fly out through the esophagus, out of Trenton's mouth?
