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.

no, it’s not.
you’re tensing the muscles and holding it taut. try relaxing your mouth – see how your puffed out cheek deflates, and the pressure equalizes between the two sides? that’s because you’ve relaxed and both cheeks are now ‘floppy.’
