Surprise Chastity Security Piercing

Take him by surprise and force him to be strapped and locked to a chair or bench while he has the base of the top of his penis pierced (for added security in the Chastity Device). 

You may need a girlfriend or two to help you with this. 

Make sure he's blindfolded before stripping his pants off and getting on with the procedure.
