The first pr0n movie i ever got was from a friend who went by the name khaki. he had one of those compiliation tapes that had 3 movies on them. the first movie all i remember was the name 'klinik' and was probably one of the best videos i ever saw. it had little short stories to each scene and (as strange as this may sound) they were actually very interesting to watch. not just for the sex, but they ended with a twist. they were like episodes of Twin Peaks with hardcore sex. It was amazing. one scene i could have sworn starred the lovely Lucia Mendez (maybe not her but someone who looks pretty similar).
The 2nd video was Black Girls Do It Better with Sahara and Angel Kelly (yummy) and i think Buck Adams.
The 3rd video was Anal Annie and the Magic Dildo. This one was not as stroke worthy as the other 2 but it did introduced me to Nina Hartley.
One of my friends however lost this video (at the time i was living in italy) and Khaki had become expensive so i was forced to get the local stuff. The first videos i got i still remember (amazing). They starred Lilli Caratti and were Una Ragazza molto viziosa and Il Vizio preferito di mia moglie. It wasnt, however, until i discovered a video called Manbait that i finally realized i was hooked!

BTW: if anyone knows the name of that 'Klinik' video i would appreciate it. All i remember was that it had many different stories with really good plot twists at the end. One scene had one of the girls fantasizing about being a housekeeper and getting into a threesome with the main couple of the house.
