For a lot of SM lovers this word is music to their ears, because in doing SM, the main part is the brain part. Your body is used as an accessory but you will experience everything through your brain.
Of course you can play with your body, but playing with the mind is on a different level. By this an emotional bond could emerge between Mistress and slave that goes beyond superficial pleasure.
Sometimes this is balancing on the edge of safety but that makes the game more attractive to play. To creep into the mind of the slaves and find out where the borders are and bring out their hidden desires, the female or male sides, the horny feelings and alertness.
An SM game does not start by entering the Studio, in fact it is already started by reading this.
Game on!
