Might be a long shot, but there's a pro domme called Goddess Bojana, I think she's Serbian. I've never seen her doing any tickling but she dabbles with foot stuff. And she's definitely popular, if there's any community, she'll know about it. Maybe you should try contacting her somehow, if there's anyone active out there, she might know something.
The closest I could get to you is Szeged, Hungary lol
