@research purposes: that looks like it was a devonshire video, by or produced by Simon Devon. She was one of the early bondage sites on the web back in 1998 to mid 2000’s I think. They closed down a number of years ago. I vaguly remember they posted something on their page about the trouble of running the site and dealing with keeping minors and other issues in check just wasn’t worth it, but I might be wrong about that. Her things float round tumblr and the web to this day.
