Weird Image Inspiration

In this set I have no idea which came first since I don't know who the artist on the right is.  The one on the left is Glen Fabry in one of the paintings done for the comic book Preacher.  I just thought it was particular that an image of a winged demon on top of another figure one resembling the act of sex and the other in the act of sex.  Strange and full of impact and debatable on whether one was inspired by the other.
