Cas' little sister (Dean Winchester)

Fbi

Dean's POV: y/n was still hurt, I felt bad for leaving her. Sam, Cas and I had to go to the local authorities about a recent attack. People's hearts torn out and their blood sucked out of them. A vampire and werewolf working together? No it couldn't be. A vampire werewolf hybrid? A werepire? A vampolf?

I can't help but stare at y/n, I liked when I held her close to me when I slept. She moved closer to me and slept peacefully. She may be an angel, but she's perfect to me. I couldn't help but fall for her, she's adorable, she's funny, sweet, loving and perfect.

*dean kisses your forehead and pushes a piece of hair out of your face*

Dean: we'll see you later angel.
Sam: Dean let's go.
Dean: coming.

*dean leaves and he quietly closes the door and locks it.*

Cas: Dean.
Dean: what Cas?
Cas: stop making moves on my sister.
Dean: what?
Cas: stop flirting with my sister. She is very naïve and gullible. You hurt her, I'll send you back to hell. So I suggest you stop making moves on her.

Later

You wake up and see that the guys left, you got out of bed and limped to the table and saw a note.

Note:

Hey y/n, we got a case. We didn't wake you because you're still recovering. Be back later, no leaving the room. See you later angel. Get plenty of rest.

Dean xoxo

You couldn't help but smile, you loved when Dean held you when you both slept and he said he wouldn't force you to do anything. You knew his reputation with women but you were glad he didn't force you into anything. You felt safe with Dean and you started to get feelings for him.

Meanwhile

You heard the impala pull up, you saw Dean kiss another woman and it hurt you. You felt your heart break and you felt your eyes fill up with water. You then flashed out, hurt, confused, betrayed and heartbroken
