This looks like a hot video clip from the 1984 movie "Educating Nina", with porn stars Nina Hartley (wearing strap-on) and Karen Summer (receiving strap-on)? Nina would have been around 24 or 25 years old in this video. (It's now 2018 and she's now 59 yrs old.) Feel free to correct me if I'm wrong.
