I've read the posts on this thread, and I'm having difficulty grasping what seems to be two different approaches to this concept. I have no suggestions for the OP, since this activity is something I want to try, but have no experience. My problem lies in the different approaches taken by people posting in.
I thought that "role-playing' was essentially a fun way to explore some sexual fantasies. Even if they are rather hackneyed, like the schoolgirl/principal role-playing, I thought it was supposed to be light-hearted, and not the end of the world if someone slips out of character.
The idea that a smack to the face would correct a fit of the giggles seems to move the whole enterprise onto a different basis.
^^^^ Like I said in my earlier post, if you can't stop laughing or take the situation seriously, your master giving you a good hard smack in the face should help you view things seriously and with more consequence for your bad behavior.
To me, if the role-playing is just one facet of a serious dom-sub situation, then serious punishment will be an acceptable part of that. When I imagine my partner and I assuming certain roles it would be, I thought, an amusing and arousing form of foreplay, and if either of us had a problem "staying in character" I feel that " a good hard smack in the face" would be the last thing either of us would expect, (or even accept).
I may be missing a point here, but I'm concluding that there may be two totally different approaches. One where the "game" is taken very seriously and not staying in the role would warrant severe punishment. The other where the "game" is just that, and the activity is seen as a chance to carry out acts not usually accepted.
