Marilyn Chambers' Sin, Sex & Science - Who's the Blonde Actress?

[UHGAM]

Good evening. I'm trying to determine who the blonde is in the first scene of this film (linked below). I know you guys probably won't be able to view the scene, but I'm hoping someone happens to know.

This is a movie that's frequently played on Cinemax as well (Best of Premium Link Upgrade Book Three).

Thanks for any help.
