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.

After a minute of shifting a mouthful of air from one side to the other, your non-inflated cheek is more “flexed” than you realize. It doesn’t take much to not inflate, so while it doesn’t feel like you’re consciously flexing the cheek to keep it un-inflated, you are keeping it taut.
