Wanted to find a copy of this one, starring the lovely Louise Hodges, but the number you quote is 51957 which, on the Your Choice site shows up as Super Freaks 6. A very nice video, I'm sure, but NOT what I was looking for! Their copy with Sperma Klinik on it is part of a 2 film dvd entitled Big Tits/Sperma Klinik and has serial no 51597 on it. Could you update your records please guys?
Many thanks for the tip on this one though! Keep up the good work!
