An excerpt from an entry by Mistress Jenn that clearly captures the difference between play scenes and a true ongoing D/s dynamic:
… What I realized is that I don’t want instant obedience I want instant acceptance and willingness. I don’t need to make arbitrary rules to get that. I need to, have I think, trained him to accept my rules completely as they happen. If tell him to lick my feet in the grocery store I want instant mental acceptance of My right to do that. I don’t need to make 24 hours to do that. I want that mental acceptance all the time. I’ve got it. Why take something so great and bind it to something that doesn’t matter like ‘this saturday’. I will never do that again. If I want to play interrogator and captive it will be spontaneous and fun and lively…just as I am. I will never again force something to happen. Why would I when I can have it all anyway.
A lot of things to say I think.
