What you call a presession "consult" is very common but it has a tendency to get shorter after the first session.

The twaddle in your next to last paragraph is something I've seen in several of your posts in the last year or so namely the idea of a Domme "seducing" her CLIENT (yes I know you hate that word) into agreeing to things that exceed his hard limits. This boils down to your obsession (another word you hate because it fits so perfectly) with the idea of SuperSadist Mistresses whose primary motivation is to inflict unbearable suffering on another human being and not to earn money.
