Lost vintage porn!

Well, lets try this again.

I'm looking for the first porn I ever saw. This was back in the 90's. So, I'm guessing the film its self was shot in the 70's or 80's.

The scene I remember takes place in a bedroom between a man and a woman. The man is laying on the bed watching the woman, and he's rubbing his junk on one of her shoes. It's odd, but I hope that stands out enough to ring someones bell.

Please help my brain. It wont let it go.

Please comment if you need more information on the scene.

Room description: The camera is at one corner of the room, looking across at the opposite corner. I recall a small upright dresser with a bed against it on the right wall.

Characters: Male was an average Joe. The girl had, I believe high heel shoes and long curly hair.

I watched this movie around '95, so I want to say it was a 70's or 80's movie. VHS.
