The fact that people tell you not to put a balloon in your mouth because you might choke doesn't mean you should deep-throat it to your esophagus and exploit the loophole.
I'd be worried that it would pop part way down and then there'd be ballon fragments in my stomach. Those could actually block up your intestines. People have died from less.
I'm gonna have to burst your baloon, but the first one is fake.
Look at her throat, nothing happens. Because she's not swallowing anything. Not a single muscle in there moved when she started to push the baloon in. Which is ******** , even on this site there have already been gifs that showed how it really affects the throat.
I bet every part of baloon she sticks further is being deflated to create the illusion. Or something similar.
