Try to use more than one camera if possible, and get some different angles. A fixed camera gets rather dull after a while.
Some F/M has too much close up focus on the tickled victim's body parts, and we don't see enough of the Ler. This problem is even more severe in F/F films. The thinking is that people are only interested in seeing the victim tickled, and it matters not by whom or what.
I'm a fan of F/F and F/M because I like watching female lers going after both men and women. I like scenes in which the ler is visible. Not necessarily a full head to toe, but at least some feminine part of her, such as her breasts or her hips.
A good example of what I'm talking about is this one particular scene in the Harmony movie TK7 - Ticklish Interrogation. Misty Lang is holding Catherine Beaumont's feet (tied together at the ankles) against her ample breasts with one hand and tickling them with her free hand. Extremely hot.
Another example was an F/M film in which the camera angle for a few moments was from directly behind the tickler's bottom, in which her butt and thighs were very close and you could see the tickling more in the background. Extremely sexy.
The Ler's face is the most crucial. To see the satisfied look on her face as she puts her victim though ticklish hell, knowing that person is in the throws of torment but plowing on, regardless.
That's what it's all about for this ticklish guy.
