You`re right Derk, together with Karina, Yulia has the same shyness and of course a worldclass body. I think PW did feel the same because he followed her demand to stop in a moment where not many men would stop. What I love so much are her red cheeks
You see exactly in the clip that the meeting with PW was very important for her, because five months later she is no more a girl but a very gentle young woman.
I tried to follow Yulias career a little bit and I am not sure, but I think she now works for Rocco Siffredi, in some new movies ( Rocco only as producer ) she is acting and if not it is her twin sister.
