Does anyone know of any fics with the following?

1. Dean is the PA. (I've read a gazillion fics about the reverse, but i was hoping for this?)
2. Dean is a model, and Cas is his photographer?
3. Okay fine. I cave. Dean as someone famous and Cas as his PA.
4. I have a bit of a literary kink. So anything where Dean and Cas are authors, editors, in the publishing business, study english, teach english. Yeah.

Thank you so much!
