Okay, here's where it gets confusing...
The girls with the shorter girl usually goes by the name of Dasha:http://tryal.ru/forums/thread/234459.aspx
The other girl usually goes by the name Julia at michelle7.com, but I don't have any sample galleries. They also feature together in several michelle7 sets.
And the only way they are Swedish is if Kiev happens to be a district of Stockholm... :)
