Having done a word search. I have described two things as Rapey,

Silver Phoenix by Cindy Pon: which had three threats of rape, a tentacle monster and an actual rape in the first forty pages of a YA fantasy novel, with no reason I could see other than angst and to move the plot along.

Lock & Key the audio play, which had a gratuitous rape and murder of the MC's mom, and then pretty constant rape threats for as far as I listened. They... didn't really add anything?
