Keep fighting

You try to run away, but Rex’s grip on you is too tight. You throw your head backwards as hard as you can, hitting Rex just hard enough to get him to release you for just a moment. You throw the door open and sprint down the hall. You turn around for a half a second to see Rex running after you with a couple drops of blood around his nose. You throw the front door open and sprint out to your car, cage in place.

You never did get your cage off, there was no reason for it to be taken off, your dick being so small and useless.
