like most subs ( i think), I use the safe word as a "safe" word. I happen to like receiveing pain in certain ways and my loving Mistress is a sadistic giving woman. She is very good at changing up at just the moment when I might use one, she off to something else. and I love her for it. The more she enjoys I enjoy, it is the play that stimulates the relationship. She has yet, to punish me, but I feel ( oh god I hope ) she would show the concern then as always
