You don't, thats the entire point of guest mode. It prevents guests/students/customers/employees from stealing the disc.
You can force the computer to turn off holding the power button 10 seconds then hold the mouse key after the boot chime sounds. That will eject all the optical drives.
Depending on the login settings, you may not be able to log back into the guest account.

I was trying to watch a DVD and inserted MY disc. It is out now. Holding mouse button while rebooting.
