Great idea and actually very simple. A few improvements: Make the piercing on the cock bigger and remove the metal ring so you can get the white plastic pin straight through the pierced hole. Then use the none-replaceable plastic lockers with numbers on and the plastic chastity device can be used when passing through airport security. Should be impossible to pull the cock back and out. So, again, great idea!!
Very smart getting the piercing. I would probably slip into my foreskin and jus pop out. I tried to wear a penis hanger once while working it didn't work out to good
