Well, so far none of our scenes have been so intense that they could get that far out of habd, you know? And I'm never gagged, so he can tell by the sound of my voice when I really want him to stop, and so far, he's never gone beyond my limits. (As soon as I reacted so negatively to the slapping, he stopped and comforted me. He knew my tears weren't just part of the game.) So for now, I find the lack of safeword to be truly erotic. If I'm ever playing with a different dom, however, like at a play party, there sure as hell will be safewords, and my Daddy will be there to watch over me.
