This is not fanfic but I'm pretty sure it's idfic: Songs You Know By Heart by Dr. Noh.
The song goes 'porn, porn, constantly borderline noncon porn, porn, porn'. A jerk with a secret heart of jerk takes a stray youth into his home for no reason. I love this story, it makes everything beautiful.

(I can't really think of any fic that fit into this category for me, but trying to has filled me with the urge to write my favourite characters as construction worker cowboy princes...)
