They are definitely a bonus when a Mistress is looking to put a slave into inescapable bondage.
Chains. Big thick heavy chains. Coupled with a few padlocks can guarantee that the slave will be just where you left them. Usually quite frustrated but accepting of the inevitable.
I have to try to be mindful of what the slave is wearing as it so hard to try and dress one when they are dripping in metal work from every corner.
The motto of the story? Be careful what you wish for – it may just come true.
