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.

Tried it myself, definitely using cheek muscles. Cheeks are just naturally soft and squishy, which is why it feels like your cheeks are still “floppy” from the outside.
You can feel it if you put a finger inside your mouth and do the same “putting air in one cheek but not the other” thing. One cheek is definitely tensed on the inside.
