I think she went by the name of "Alina", supposedly a Ukrainian/Russian whore. This guy is a serial monger and books and records prostitutes and posted it on eather reddit/4chan or 7chan I believe.
Thanks for your reply, but she is not Alina (aka Celia aka Ninoska, see my post here viewtopic.php?f=19&t=16045&p=320244#p320242) this is a different girl and, maybe as you say, she is only one of the other prostitutes/escorts that he "worked".
Now, I only wonder if there is a complete video (maybe in higher quality) other than the 3:45 minutes that one can find googling "Amateur blond secretary fuck and suck"
