Dream Bondage Device - Molded Metal Restraints

I had debated writing about these since they are complete sci-fi fantasy fiction that happened to jump into my dreams a while back and made several appearances when I dreamed about similar worlds.  But hey, someone might find them hot, so I figured what the hell.

I had a rather intense dream that happened in a country where men were enslaved, controlled, and monitored by women.  Each male wore a pair of metal cuffs on the wrists and ankles, a belt, and a collar.  They were solid metal without any seams or openings (read as: there was no way to remove them).  Inside each of the restraints were electronics for monitoring location/GPS and health status (pulse, blood pressure, arousal, etc.) as well as capable of delivering punishment jolts to various parts of the body. 

Each of the restraints had an electromagnetic locking feature.  On some flat spots on the collar, cuffs, and belt if the electromagnetic lock was activated, one item could be "locked" to another one via electromagnets.  Wrists or ankles together, wrists to the collar, wrists to the belt, etc.  Also, tethers could be inserted and locked to the flat spots forcing them to be connected by a chain or cable and secured to the item by the same magnets.  In the world where the dream occurred, there were areas like hitching posts as well as spots on walls where subs could be secured by the electromagnets to pads on the posts or walls.  The configuration of how they were to be secured was dictated by a woman via remote control.  The pull of the locks was so strong that activating them would actually pull the limbs to the desired locking position and these devices were worn below the clothes since clothing would not interfere with the pull of the magnets. 


Thankfully, one of my dreams actually involved the application and explanation of these so I have some idea of how these work.  Each of the items starts out as a set of electronics encased in a flexible and mold-able substance of a similar consistency to fresh clay.  The items would then be molded around the body for a snug fit.  Once fitted, the clay-like substance was treated with a liquid that would cause it to solidify into a hard metal alloy that wouldn't rust and was nearly unbreakable. 

There were a few variants including both a chastity device that was part of the belt as well as a head harness that included an in-mouth gag that had an on/off switch allowing or preventing free motion of the jaws as an eye shield that could be made clear or opaque via remote.

Plot holes in the dream:
-Constant exposure to strong electromagnets would likely cause cancer in the wearers.
-Since they were molded snug to the body it didn't allow much for that area of the body to get larger or smaller due to weight/muscle gain/loss, making them not quite so feasible.
-There wasn't ever a notion that they could be removed since they would be impossible to cut (this was alluded to) but this further conflicts with the 2nd point.  This could be rectified if there was a similar process for converting it back into the softer material but that was never brought up in the dream and this would dull some of the "extremeness" of the situation if there was a possibility of removal.

Yes, these are far fetched, but the idea of a permanent restraint device that could be worn under clothing while giving your Mistress full status of your location, physical status, and the ability to execute punishment or restraint at the touch of a button is kind of a fun thought.
