We're not entirely sure what "Black Snake Oil" is, but Julia De Lucia starred in the 2016 video by the same title. We can only assume that it's some kind of secretion that needs to be sucked out of gashes promptly before it gets into the bloodstream. There might also be some pornographic subtext here since the girl in question is a porn star from Romania. Come to think about it, we've never seen a girl shake a scrotum about like Julia when she's chugging cocks. Julia worked and lived in Mallorca for three years before becoming a regular at porn industry shows like the Venus in Berlin.
