I'm not sure which scene is referred to here...
In her authenticated interview, Lucy did say that she relished the chance to have sex with black men, and she mentioned specifically Gangland Creampie 8, in which she features as a Christmas present:
and also Black Pipe Layers 4, the famous scene in which she is overwhelmed and has to take a break by the window.
But in both scenes, it is three, not two, lucky black guys who play with Lucy, and she is more like 20 than 18.
The earlier interview, which I recall reading first in Spanish, is also the source of the information that having left porn, Lucy worked in a bar in Prague. That is a few years ago now, but one can imagine her still enjoying this fairly easy lifestyle.
My guess is that she made some good savings in porn - clearly not a flighty girl who would waste money on fancy clothes, much less drugs - so she bought a couple of apartments back in Prague, and lives in one while letting the other to tourists.
She said in the interview that she retired because of an STD scare at the time and also no doubt to avoid doing her body permanent damage. That her parents expect her to marry, and she would like that but is not in a hurry. That she still loves sex but is not as wild-crazy with it as when she was younger.
Again, only surmising, but you can imagine that when a Black tourist strays into Lucy's workplace, he gets the delightful surprise of her number written down on his beermat. And whenever a northamerican basketball team is on tour in Prague, Lucy is the first to know...
