"Scientist Creates Perfect Ticklish Woman" CUE-1 from Close Up entertainment.
First Licking video Lorelei produced, before she started doing them for Harmony, and it includes Cathryn Beaumonts (the girl pictured) first tickling work , as she just turned 18 and was legal to use. Ashley Renee is in it also.
If memory serves, Renee has no lines whatsoever in it (though she is made to laugh a lot). It's that scene with Beaumont that is the standout, though. I loved the way the hand kept creeping back into the camera view to torment her soles. I believe it was supposed to be a "dream sequence", no?
