A slave is kept safe and sound, isolated from any threats. 

I wanted to do a story linked to the lockdowns for a while and finally came up with this story. The idea of someone using them to put someone in extended bodage or imprisonment is an interesting scenario. 

Also the second story fully from the master's perspective, as I think the broken slave's perspective would be quite s8mple by this point, probably something like in the story permanent bondage, where they're only aware when used and played with. Plus I like the crazy mind of the master in this one.
