Just wondering how many like to incorporate games (complete with rewards and penalties) into a session?

I love this kind of thing and have often done stuff that resulted in penalties that could include X number of strokes of CP, Y minutes in challenging bondage, a set amount of electro play or other sensation play. etc etc

Rewards were a certain amount of teasing/edging/pleasure play.

I've played both guessing games and a game where I had to remain motionless and silent while she teased and edged me trying to provoke a reaction.

The Domme can obviously rig the outcome but I like the illusion that activities are somewhat outside her control. That sets up a scene where the Domme can play being kind and sympathetic while inflicting severe punishment. A sort of "Oh dear, you poor thing. You got 4 demerits. I'm so sorry, I hate to do this but the rules say I have to give you 40 with this strap now."
