Inverted Theory: a BDSM dungeon master finds an advertisement for people wanting a Dungeon master and it's not the kind of Dungeon Master that (s)he was expecting.
so a pen&paper game, where the players and the game master have to demonstrate what they want their characters to do?That sounds like fun, "Dungeon Mistress" + Pen and Paper Group. Should be one girl in the group as well for some diversity ;-)
