Wow, this is a bit different for a chastity device !!  An all stainless steel egg that encloses the entire cock and balls and it locks.  To add an extra touch of chastity, within the egg itself, there is a circle of "teeth" to make the user think twice about getting an erection.

If you want to go a step further, elecrify the egg to add another element of excitement to the users mindset.

Devious indeed and a must for the serious Dom!!
