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.

Try inflating your one cheek more and more. I alteast notice that my other “relaxed” cheek get’s less and less relaxed. I am almost like pressing that cheek together.
So yeah, the other cheek is not relaxed.
Or try sucking in the air in only one cheek. You will notice quickly that your other check also get’s sucked in but to a lesser extend (because you are working against it, but your muscles or not as good in that direction).
(Btw, great question, I had to experiment myself)
