Who is she? Where to find more videos?

I think that is right. Clarian The Librarian
I don't see this exact pic on the tumbler, but it looks like her. Looks like she hasn't done anything since 2013, but here is her tumblr where she has the only picture I can find:
http://clarianthelibrarian.tumblr.com/

Here is where she used to sell her videos, but they are all gone now:

http://clips4sale.com/69413

Her Twitter seems to be deleted:
https://twitter.com/Clarianxo

Her FreeCams homepage looks bare:
http://profiles.myfreecams.com/clarian

Looks like she made an XVideos page for herself, but it has no videos:

A copy was called "Big Brother Masturbation Humiliation Revenge" on Motherless.com, but that video has been deleted:


Here is an additional cached image of the video, but it is also deleted there as well:

This page has a link almost at the bottom called "Big Brother Masturbation Humiliation Revenge Part 1"
http://www.aisextube.com/tags/sister%20masturbating
but it goes to a page that gives and http 500 error
http://www.aisextube.com/video/#4367151

This page shows the thumbnail for the motherless video, but obviously doesn't show the video:

here is a Reddit where someone asks the question, but the answer is deleted as well:

The quality seems like a smaller studio, but I didn't find anything matching that title in Clips4Sale.com. Maybe this will help someone else.

Looks a lot like Tiffany Furlan but differently not her.
