Null Cage

A soft, comfortable, custom tailored nullbulge to be worn without a need for a suit or belt.
(All custom designs, will require measurements of the user.)
Comes in a variety of different "Securities"
Minimum - For light play, no real lock, mostly for show.
Low security - The equivalent of a loose-fitting cock ring.
Medium - A tight flexible band, may cause irritation if left on for too long.
High - A standard lock and key, with a tighter flexible band.
Administrative (Silicone Only) - Nearly impossible for the sub to take off by themself. Utilizes a brass ring with tiny brass screws to lock the chastity in place. If the chastity is attempted to be taken off by the wearer alone, there is a great risk in which the wearer will be stuck in the chastity.
The best option from there is to use bolt cutters to snap the locking ring.
