I LOVE this kind of stuff, where tickling occurs where it's not necessarily supposed to. Also known as "accidental tickling"
This one is called "PEDICURE Black and white design 🌸 Feet that are ticklish"
*warning* there a little bit of gross extreme close up pedicure stuff (callous filing, digging under nails, etc) early on, if you're not into that fast forward, but from 5:00 - 7:15 mark she breaks out the files and "special devices" on this ticklish (and beautifully shaped, I might add) foot and you can tell the recipient is going nuts from her body language. Unfortunately you can't see her face, nor can you hear her laughter, but there are some funny cartoon emojis that convey that she's laughing like crazy during this pedicure.
Anybody speak Russian and can translate?
Anyway, enjoy!
