Destiel Smut (Demon Dean)

This is my first time ever writing something like this, and I hope whoever reads this enjoys!

The story is based on a Dean Whinchester that runs away from Sam his younger brother and Castiel the Angel that had been by their side for who knows how long, one day the Angel sees Dean and goes to confront him not knowing that he is now part demon and filled with anger and lust! *wink wink*

Btw the art is not mine!
