I have seen a few clips that feature this: Two girls in bondage positioned so that they can tickle each other. Does anyone know of any great clips that have this?
It's not strict bondage per se, but I filmed a scenario like this as the conclusion to "Barbie vs. Natasha"; I tied them both together at the knee and told them to tickle one another until one safeworded.
Best clip I ever shot, imho, and now it's available as a standalone for folks who didn't want to buy the whole clip.
There is a classic Magic Touch clip with three girls tied in a triangle (each has one leg tied to her neighbor) and they all go at each other at once. If you ask Jeff in the MYTP forum I'm sure he'll point you at it.
