It is Danni and Sarenna. It is a vidcap taken from a segment from the E! channel's "Wild On" series.
IMHO, it is singularly the GREATEST segment in the history of the universe in terms of showcasing GI-NORMOUS boobs. In the scene before the one from the pic, the camera actually focuses in on Danni's cleavage as she bounces her HUGEMONGOUS naturals. They look bigger than I've EVER seen them in that scene.
In all honesty, after I saw this segment, I actually faded away from the whole BE scene because I had the view.... "well, I've seen enough to know I've seen too much"...
As to whether the pic is allowed, I don't know.
