Extremely intense, restrained tickling, with either lingerie/swimwear or nudity (whether lee wears mask or not is fine with me, either way), and you have a lifetime subscriber with me. I have found some of the OF folks out there that do tickling stuff aren't always going hardcore, and instead it's soft/light or teasing tickling, which is fine.
There's definitely a big market for lighter/teasing tickles and of course clothed, but also good demand for the intensive, tickle-to-safeword-type sessions. Just my two cents
Note: Again, masks are cool, as long as I can see at least the mouth and/or the eyes. Always pleasant to see the laughter and desperation in the mouth and eyes
