My first favourites came from the first tape of porn I had a copy of, 3 hours taped from a channel called Eurotika, and my favourites were from a feature that I didn't take note of the name, favourite girl being "blonde with big tits getting fucked next to some rocks on the beach then down on the sand in doggy style before getting cum on her pussy."
There were numerous one on one b/g scenes all over the beach setting then finally at the beach house a big orgy scene.
Secondly however was a feature that some scenes really stood out in my mind and due to remembering the plot all these years later, I was able to ascertain that the film was Legend Part 3 and the actress was Lauren Hall. The wonderfully camp "PP" (Mike Horner) is getting "Linda" ready for her first scenes and tells her"We just need to work on your acting technique, and your orgasm technique." Linda/Lauren responds by saying "FUCK the acting, let's get on with the orgasm technique!" and drops quickly to her knees and sticks PP's dick in her mouth. Wonderful.
When I got the Internet my first favourites were Jenna Jameson, Nikki Tyler and Chasey Lain.
