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.

You’re using the muscles in one face cheek to contract, tightening up. This pushes the air to the relaxed, floppy face cheek.
The same happens with the water. You’re using muscles to direct the water where you want it to go.
