Try to resist

You try your hardest to hold out against her powerful squeeze, not wanting to tap out to your little sister, but there is only so much you can handle.

"Oh, is it too tight in there? Getting a little claustrophobic maybe?" She mocks while maintaining her crushing squeeze.

You have never felt anything like this, the intense pain and compression of your ribs rapidly take a toll on you and you can feel yourself quickly reaching your breaking point.
