Actually the "milking table" videos were out before the other. The "milking table" videos were from the early 2000's. They had a website and everything. That was when porn was just beginning to be popular online. Lots & lots & lots of people started posting videos of just about everything/anything and the websites soon followed.Honestly, I can't remember what they went by. It was something with "milking table" that was specific to her. But now if you search that, it's a whole different (while still similar) feel - usually a guy laying face down on a table with his cock through a hole.
The guy in those videos was sitting on that toy that had a shaft vibrating in his ass. She would turn it up and down and stroke him and others until they came. These were some of the first videos that really started to peak my interest in being fucked from behind.
