Who are they and where or if I can find more about these two

Found these two while drifting around the internet in more than one site, a quick "google image search" leads you to a variety of sites with two separate videos of 'em. However I couldn't identify the origin, so I could go directly to them. They are tagged as twins (being true or not, its how I found them through multiple sites).

They seem to stream or something like it, but couldn't found a name or anything. A video links to maya29x, but its not them.
