This is exactly what I've been saying for years. Any video producer who follows this formula will instantly make many thousands of dollars, with three simple rules.
1.) Book someone for a "bondage" video, where the contract contains a list of approved activities, like "model agrees to appear in a video which could include depictions or scenes of struggling, pleading, confusion, disorientation, tickling, obedience or capitulation." Get the contract signed in advance. (If asked about the tickling, a nonchalant, "yes, there could be some tickling" should suffice. If pressed on the issue, a "look, this is just our contract, you can sign it or not" should do the job.)
2.) Ease into the tickling slowly, but then build to maximum intensity.
3.) If at any point, the model truly sounds like she's scared for her life, having an emotional breakdown or is truly traumatized, then simply stop. The great majority won't be. Trust me, I've done this many times in my private life -- most girls just laugh, a few like it, but even though most will be highly annoyed with you, most are not psychologically traumatized -- but again, if they express that they are, you just stop.
Detractors always assume that non-con'ers have Asperger's and will have no ability to hear other human beings, and so these detractors can't seem to wrap their heads around my rule #3. In fact, it would work quite easily and would lead to a new crop of completely kick ass videos, without the fake, exaggerated-for-the-camera laughter that can be heard on most videos today.
These three simple steps would lead to a creative breakthrough in a video genre that's become quite stale the last five years.
