It doesn't even have to be a real slap. Something symbolic, my hand cupping her chin, extending my fingertips and regrabbing her chin including the side of the cheek, has all the intent of a slap, gets the same emotional reaction, and establishes her submission... when something has occurred that garners a moment of rebellion.
Yep that also does it for me... sits back and hopes Master gets that way tonight..
