There is no air tight barrier in between my two cheeks, so how am I controlling the air in my mouth and directing it to one specific cheek? The deflated cheek is still floppy, so it’s not like I’m tensing a muscle to stop it inflating.
Also works if I have a mouth full of water, and can also be directed to top and bottom lips.
Thank you.

Sitting here and repeatedly moving air from one side of my mouth to the other tells me that what’s happening is that you’re not allowing any air/water to go out of your mouth, either through your throat or your lips. Additionally, your “empty” cheek might not be as tense/distended as the “full” one, but it’s not exactly floppy–you’re not allowing any air/water to be in that cheek, which puts pressure on the contents of your mouth and drives it to the “full” side.
