It sure is a fall from grace.
I've talked to some insiders, all of them said that they were hard working girls.
It was not an easy decision, but I guess they ran out of money, it lead them to Vegas, stripping, escorting, ....
That's the dark side of being a Playboy playmate, you have the world (and every man) at your feet at 20, if you do not manage to find a movie star, sports guy old man to marry, you'll be a 30 years old girls being asked "did you ***** with Hefner?"
Other playmates aren't in a better place.
As for the scene, I saw the trailer, while these are not the girls that I saw in Beach House or other shows, the make-up staff at Brazzers did a work of art, they do look good in the scene compared to what you see elsewhere.
Another thing, I guess their inaugural scene was not with Keiran Lee, I guess they were afraid from the way he *****, yes I know it's consensual and scripted, but the way he does it (*******, slapping,....) is more like what facial ***** than sex, and you know that it drove so many girls out of porn.
We'll have to wait and see.
