Nothing stays a secret forever (Destiel)

Cas is human and lives in the Bunker with Sam, Dean and Kevin. Sometimes they go hunting but it's mostly quiet in the supernatural world. After one particular hunt it gets hard for Dean to keep his feelings towards Castiel a secret any longer. But what will happen if Cas finds out what Dean really feels about him?

This is my first Fanfiction and English is not my first language, so please be nice! . The Fic is set nowhere special I am just taking all the facts and mix them up so please don't be confused when I mention things from season 11 although Cas is human. Also I will not accept the fact that certain characters are dead so in this fic they are not. I don't own any of the characters, but i do own the story. Enjoy!
