I can just agree with you Dragon's Muse, though you've got longer and deeper experience than me. It's not a simply military command relation, it's about trust, and no sub in his/her right mind would accept that the Dom/me razes down their hard limits without flinching and damages them just to demonstrate the total power trip (this happens in fantasies of course, kidnapping/rape and the like, but fantasies and real brute reality are two different things)

I wouldn't expect Mistress to order things that would hurt me bad or put me in irrevocable grave danger, but I do expect her to push me deeper into submission, bring out the slave she wants to see, and to some extent impose her wishes on me. Slave louise handcuffs herself and gives Her the key, to keep for as long as She wishes.
