Hi Isreal!
I'm sure that's from an FM Concepts video. Don't know which one. probably just go to thier site and browse through thier videos. I think they have like 600,000 videos. LOL! Just kidding. As far as the realism goes in thier tickling vids I'd have to say it's questionable at best. We have a lot of thier tickling vids cause they're the only place you used to be able to buy tickling vids but I think there are better places to get tickling videos from, although I have to say there are the occasional good tickling scenes.
I may be wrong, but I'm about 99% sure that the ticklee is Sadie Atkins. It sure does look like her in the facial features. I checked tickleparty.com where you can purchase FM clips and didn't find it under that one though. Maybe it was just a photo shoot??
