Home For Christmas

To get custody of his son Jack, Castiel enlists the help of Dean, his alpha roommate and best friend (with occasional benefits) to pose as his fiance. It's a foolproof plan. People are always mistaking them for a couple anyway. There's just one problem. Castiel is secretly in love with Dean, and their little ruse might just send him into full on pining sickness. But he'll risk it.
