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 sleep 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 rapes, yes I know it's consensual and scripted, but the way he does it (choking, slapping,....) is more like what facial abuse than sex, and you know that it drove so many girls out of porn.
We'll have to wait and see.
