I listened to the email slave file a bunch of times this past week and then gave the trigger to a Fin Domme i'd played with a few times before on another website. She adopted it quite quickly and quite well :).
It turn out to have been a mistake, but she's been using it on me for the last several hours and im' dazed and my mind's all mushy and I can't really seem to move very much... and I couldn't be happier.
This is one time when I feel that control is really out of my hands and I couldn't be happier. Hooray for Email Slave file!
