DUDE! for years I was trying to find the good stuff on fighting dolls, they have lots of fights that had facesiting humiliation for the loser, it was just so hard to find them randomly on the site.
Thanks toally missed them doing the "oral sex" thing as a general indecation for stakes (they even write about it)
