movie 1 is a big lady playing with her breasts, she lifts them up and there are faces attached underneath them making grimacing faces.
movie 2 is a scene where a guy has a face in the middle of his ass.
anyone? anyone? sorry about the vague scenes i described.
I suggest Gothic (1986) for #1 and Society (1989) for #2.
1 is Night Angel (1990).
Society has to be the number 2. Here’s a photo for reference… probably goes without saying DEFINITELY NSFW http://www.tasteofcinema.com/wp-content/uploads/2015/01/Society-1989.jpg
