Who is the beautiful brunette that is going to ride in a tree?

I found the video on a forum long ago but have not been able to find it since. Video quality would suggest a scene made around the late 70’s early 80’s American. The woman is going to ride a guy up in a tree in all sorts of positions. The clip was unique because the actual sex was not dubbed over with some ridiculous music like most from that time. Instead you can hear her talk dirty which is more common in the newer material.
