The studio from which that clip originated- Tickle Central- were masters of producing videos that featured verbal teasing, and I fully agree that can make a tickling video so much better.
Sadly, it seems to be a lost art nowadays, but as you say, if producers want to give their videos something...
The clip with the mirrors is absolutely superb. It's a truly original concept and it really plays into the psychological aspect of being tickled, as the 'lee can't escape the tickling itself and the feeling of being tickled by multiple tools, which would surely ramp up the intensity.
Excellent...
‘Tickled Pink’ have some fabulous behind-the-scenes content on their C4S store. Highly recommended!
