Although she is not the first "younger sister who looks older than her older sister" to come down the pike...I would do her in a New York minute.
She definitely is related to Ewa as you can tell by her eyes. Both pairs of them.
Another bullseye for the people at Polish Busty, who I strongly suspect have a secret clone factory out there in the hills of Polska, churning out one busty beauty after another. Because we all know it's one thing to have a busty woman factory, and another thing to have a beauty factory, but Busty.pl seems to have a busty beauty factory!
