Just speculating a bit here:
One of the things I've noticed as a guy who loves context (most guys don't seem to care about plots or story-lines and say "as long as she's hot I don't care"), is that women really need things put into context and for a more relational aspect to make things realistic. Here's a survey from a couple of years ago of women's porn habits to illustrate this point:

That being the case, we've already had a few tickling clips like this and a few producers who try to introduce more relational aspects and realism into the picture. Granted, a lot of producers do put a lot of effort to create a story-line but it's so obviously bogus and silly you can't suspend reality and enjoy it from my perspective.
The only problem with this approach is it takes a lot more time and more creativity to come up with stuff like that. Most of your clips are going to be the garden variety 'here's a paid model getting tickled' schtick.' Which is infinitely easier, quicker to put out and get a return on investment than those videos.
