Sparrows Fall

"OH GOD YES. Possessive!Soulless Sam. Cas would be absolutely covered in scratches, bruises and teeth marks because Sam wouldn’t let Cas or anyone else forget that he belongs to him. And yeah, sure Cas is an angel and he could heal them, but he likes it. He likes that this Sam isn’t afraid of hurting him and he likes that dangerous look Sam would get in his eyes any time someone got a little to close. It would be the worst after Cas kisses Meg."
