Don't forget to focus on quality, also.
I prefer very thin, barely-there, no RHT, flesh colored or suntan pantyhose, because it photographs better than the thicker or shiny kind.
Make sure the set is well lit. Bring in extra lights. The more light, (up till it's all washed out) the better. And make sure the light is even, notice when you are shooting in a well lit room, everything looks great, but when you have a room with artificial with a big window, the light coming through the window looks like the aliens appearing in Close Encounters, and the rest of the room is dark.
Costumes can add an extra touch, I've mentioned harem girl/belly dancers, in pantyhose, but anything is different than the same old bikini girl strapped to a board.
How about either of you WANTING to be tickled, going looking for a tickling?
That's not done very often...
