Please help me find this video...

Before Pornhub was ruined, my favorite video of all time used to be there. It was a beautiful, dark haired woman playing the part of someone doing "research" about foot tickling. She started out in nylons and eventually went to bare feet. No bondage, it was just her letting the cameraman tickle her feet in different positions while she talked about "getting good research" or something along those lines. I think she was wearing red dress with a lab coat? I've tried looking for it everywhere, and can't even find it on Clips4Sale. Please someone help me; I miss my favorite video. I don't remember what it was called, but I need to find it again.
