Sexstation suddenly gone shy?

I was beginning to think the rules might have changed.
I watched Stella for quite while earlier today, and everytime she pointed her arse directly at the camera her thighs were tightly closed. Very unlike her.
Then French Chloe came on and was doing exactly the same.

Stella ........... Chloe

But a few minutes ago, Foxy was on and things are back to normal, see pic below.
It could be they have introduced different rules for the daytime. I hope not. Further investigation is required.
