Destiel smut/fluff/angst. My first Destiel, I hope it's okay.

An Angel and Human suffering from famine. Dean, Sam, Bobby, and Castiel have spent their time looking for the horsemen so they finally decide to hunt them down but their only in lead to one, Famine. Dean and Castiel's bickering have caused them to be left behind. What will they do all alone and hungry?

The angels have fallen. Castiel lost his grace, and is now a human. He experiences hunger, cold, need, but still pondered at the thought of love. Dean takes him under his wing and helps him understand his new way of life; every aspect. Even though his grace is lost, the affair between a man and an angel is forbidden. Not to mention, an angel and a Winchester. In addition to the internal conflicts between the two, they also have to worry about the bounty put on Castiel's head by the other fallen angels.

They looked into each other's eyes and knew. But the true question was whether or not this was right. Perhaps it was so very wrong. But they didn't care. All they cared about was each other. Includes Sabriel

Cas, Dean, and Sam have been hunting together and splitting off to take smaller jobs. The story starts with the three of them on three separate hunts. Cas is human and wounded. He shows up at Dean's motel in need of help. What proceeds is the two of them meeting up with Sam and going on an involved hunt, over the course of which Dean and Cas slowly figure out their feelings for each other. Lots of awkwardness (in a good way), some mild angst, comfort, and eventually fluff and smut.

How to make a human Castiel behave and learn... physical attention.
