These are videos from the Color Climax Series. It is a Danish hardcore company that specialized in the more er um, interesting aspects of porn (pissing, rape, teens, bestiality, bodily fluids and incest) Curiously, they obtained the rights to all of John Holmes initial forays into porn, so almost his entire early career is in their catalog. Bill the Bull aka Sampson is a GREAT find and his four or five films that he made for Color Climax are special.
All in all, a GREAT thread Dan the Man, I am proud of you for your taste in vintage classics.
