Well ladies and gentlemen, it ain't spur of the moment, and it ain't unscripted.
But it sure is a helluva lotta fun, eh?
The pool videos come from a clip store named "Tickle Tortured Babes" (you gotta love a company that sticks with the simple stuff). And that's not all.
Each bikini-clad vixen takes a turn being strapped down next to the pool and tickled.

The clips are scattered a bit throughout the six pages of absolutely hot women being tickled, so you'll just have to browse through non-pool images.
Oh, the horror.
