Burning Ball Bell Throb
by Charless X. Stain.
Another Exist to Suffer conditioning file.

This file will condition you to suffer at the words burn and burning exist to suffer,
and small bell of your choice. Make sure it is bell you dedicate to your sessions only and that you can get dirty. It is also to condition you to feel ball throbbing pain at the ring sound and vibration of the bell. You will be touching yourself with the bell, So make sure it is the correct size and vibration.

Woman may do this too considering their boobs as balls.

This may become permanent if repeated but you may react to all bells eventually so be careful.... Do to this reason i put this under curse, however to uncondition  yourself you will have to replace it with a new trigger.
