You and Cas had recently just met. He had dragged you out of Hell. He left a red hand print on your right shoulder, which is basically a claim on you. And as you two grew closer, you learned to have an... obsession, with his blood. The taste, the way it looked, the way it felt as it dripped into your mouth, the way it smoothly ran down your throat as you swallowed it. Everything about it was just... perfect. You wished you could be around Cas at all times, just to taste his blood more.

You had just returned to the motel you were staying at. Cas was sitting on the bed. When he saw you, he stood. He looked as proper as ever. All business. Always.

He said with a nod, greeting you.
