Psychotically Codependent AU - Insane!Dean/Sam
Dean corners Sam in the motel room and if it didn’t already look bad, the look on his brother’s face would most definitely make it bad.
“I’ve been rotting away in hell for a long time, Sammy, and this is how you‘ve been spending your time? Slutting it up with some demon bitch? Can’t say I’m impressed.”
Sam looks torn, like he can hardly feel the split in his lips, the bruising skin right below his mouth, and that’s really not fair because Dean’s incredibly aware of it. He wants to dig a finger into the bluish flush that’s starting to form, wants to watch Sam hiss around it, and he’s about to do just that when Sam speaks up again.
“You were gone. I had to find a way to keep going, Dean.”
It’s a valid excuse, Dean thinks somewhere deep in the back of his head, but what comes out is, “What’ve you guys done together? You fuck her, Sammy? Let her ride you? Huh? Lap up all that blood in your dirty, little mouth? She fuck you as good as me?”
Sam’s eyes shine for a second like he’s about to burst into tears, but he clenches his jaw and looks Dean dead in the eyes as he says, “No one fucks me as good as you.”
Dean feels his lips curl up into a self-satisfied smirk that does nothing to quell the jealousy burning strong and relentless inside of him, and he gives Sam no warning before kicking his shin. He puts a hand on Sam’s shoulder and soon, Sam’s looking up at him. He’s on his knees, mouth still bleeding, and Dean thinks he might lose his mind.
