This is
Mistress Rousson, an online dominatrix. She popped up in the Purple Port thread a few months ago; her profile there seems to have been deleted.
Be that as it may, she seems to be making videos these days, where she asks her worshipers and slaves to give her money so she can make more videos just for them, where she will show all of her breasts if they behave. I did come across one video of her at one of those free porn video upload sites; I'm sure there are more of them out there.
(I note that I really wanted to post one of her sample GIFs, because it's the video that made me want to "pop", but I can't find one small enough to meet our size restrictions!)
