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.

When I do this and pull on the deflated cheek I can feel that it’s seeled / pulling a vacuum. Also true when my nose airway is open.
So I wouldn’t exactly say it’s floppy and that you’re using no muscles to do it
