Exactly Samantha. I'm glad to see so many folks in this thread who understand that the
negative version of breaking a 'lee, where she's upset and angry and can no longer trust you, is wrong wrong and a little more
wrong. It's selfish and a violation. Having said that, there's a far more positive version of 'breaking' that lurks in the heart and mind of many a 'lee, myself included. It involves starting out feisty and even defiant, and taking the play to a level, both mental and physical, where the 'lee finally feels totally enveloped in the sensation, and totally at the mercy of the 'ler to the point of feeling completely bent to their will. And
wanting it that way. Logic has little to do with what the soul wants; sometimes we feel safest when we know there's no escape, and we feel most loved when we know there's not much chance for mercy
Example: one evening a few years ago, my longterm Dominant randomly decided that he wanted me to say the word "tickle" for him. I couldn't then and I can't now, especially put on the spot that way...he didn't care. He never used bondage, he's 6'2 and weighs 100 lbs more than I do. Don't even ask me how long he tickled me that night, I have no idea. All I know is that finally he had me flat on my back on the carpet in just a short sleeveless nightie, both my wrists in one of his hands and my legs tangled up in his while he lay halfway on top of me, his ridiculously ticklish goatee dividing it's time between my underarm and my neck (bastard) and his free fingers doing terrible, terrible things to my hipbones (BASTARD). Let's not even mention that area on my lower sides that only a few of you know about...and yet it wasn't the tickling that 'broke' me. It was the way he kept whispering
"say it little girl, say it or I'll never let you go and you know I've got all night SAY IT" over and over that finally destroyed all my resistance. In fact, technically I never even said it, I remember going "Ti-Ti-Ti-T..." and having that sad attempt accepted because I honestly couldn't say anymore, I was that gone

Afterward he gave me a long rubdown and was nothing but kind and nurturing, it's still one of my favorite sessions ever. And was I broken? Hell yeah

You can definitely break someone safely. And fuel their fantasies for years.
