Looking for an extreme and permanent sort of situation of being kept held captive, heavily restrained and left isolated 24/7 when not being used, and with no chance of escape.

No need for a safeword or any limits - happy to be used, abused, tortured in any ways desired. Relocation would not be a problem wherever you are based.

If this sort of scenario is appealing to you then i'd love to hear from you and would appreciate a message.
