I don't know if this is relevant due to it being Dutch Tickler (I don't know if he's in Holland or what, although he can obviously write good English!), but what I would like to see in a video that is set in a dungeon is a lot of taunting by the ler(s), telling the lee how helpless she is, and what's going to happen to her, in detail. Tell her how they're going to tickle her for as long as they want, and there's nothing she can do to stop it because she's helpless etc.
Then give her a short period of tickling, and go back and tell her that was only a fraction of what's in store for her.
Another idea (if she's on a table with lots of straps such as RT have used) would be to have her tied pretty loosely, with just a fastening at the wrist and ankle, and lots of mobility, then tell her what's in store - they're going to tickle her without mercy, and after each period they're going to fasten more straps, making her more and more helpless until finally she's totally immobile, and then they're really going to go to town on her, maybe for hours.
If the lee isn't able to beg convincingly after hearing these desciptions, then maybe a gag would be good, so we can just see the scared look in her eyes at the descriptions of what's to come!
Not that I'm cruel or anything.
On the subject of nudity, it's not necessary, although it would be good to see someone doing orgasm denial with the tickling - tickle them for a while, then tell them you're going to make them come, get them right to the edge and then say you've changed your mind, and go back to tickling!
