This might work very well if the guy has a fantasy and the objective of the session is to fulfill it. To me a first session looks more like a game or a number of games you can play. You have to give a few pointers about which games you are into, and things you absolutely hate, in my case humiliation. I am curious what the mistress brings to the game. Could be things I would not know to ask for. The most important thing is the attitude, to try to find out what the other likes and a sense of fun and experimentation. I see myself as an active partner in the session. I do not believe in preset plans, and if a mistress cannot get the room temperature and customize her plan from the reactions she is getting this will not be an ideal session.

But if the session does not go well I take responsibility too. After all I started this, I initiated the session and I chose the mistress. Having done that I relax because I do not worry about things I cannot control.
