"Fake" translated means "stop telling the models how to react." Let them react naturally, with perhaps a little exaggeration for effect. <b>If scrubbing a brush across their feet at fifty miles an hour hurts, then let them say it hurts, not keep laughing for fear of not being paid.</b>
It has all already been said above.
You will never see the good ticklers do this kind of frenetic thing until they have established whether the model reacts to it or not. Look at TIB, at Ticklecentral or Frenchtickling. You may not like their movies, but they are able to get what they want out of their models without all the hype. They are polite, they don't force their personalities into the takes. And if you have to do a scenario, get a girl to do the tickling, or at least take part in it.
And, let the models talk, say what they are experiencing. <b>To me it is far more convincing having a model say that she has ticklish whatevers, than for the tickler to keep talking about it.</b>
It may be just me, but I find a good dialogue between ler and lee very helpful, but one that refers to the tickling that is happening, such as in the case of Guiltrip's movies in Nylon Tickling. I do not really go for nylon tickling myself, but the dialogue I find intriguing. <b>It is the sort of thing I try to get when tickling someone myself.</b>
Now I am sure that there are many people who would have better advice. I only know what I like, so a general question on what makes a good video may help.
<b>But all the advice one gets - tighter bondage, don't let her move, etc - leaves me stone cold. I like a movie in which the girl looks good, is not made to look ridiculous with a ball gag, blindfold or other contraption, and where you can see the reactions at least some of the time. Bondage or no bondage, nudity or not, is all one and the same to me. And I don't like any attempts to humiliate her, but rather for the tickler to stick to tickling.</b>
That is what I can say for the moment. Perhaps others can also contribute.
