#samjohn implied

early seasons sam time travels to the later seasons and realizes, with horror, that dean has become just like their father : the same volatile temper, barely restrained aggression when he gets mad at sam, and this unsettling pleasure he takes in control, like sam's submission excites him, gives him a rush. even his voice echoes john in a way that makes sam's stomach drop : just as low, rough and harsh as john's. the voice meant to command.

and sam realizes that this older dean isn't just playing this role. he is comfortable in it than he has ever been.

He got so fucking mad. He feels that his cock swells even harder. Dean grabbed Sam’s hips and slammed into him faster.

“You miss your daddy?” Dean growled. “I’m your dad now. I’m the one fucking you.”

He pounded Sam harder, deep and rough, then leaned down close to his ear.

dean looks like he wants to stop the car in the middle of the road to fuck sam hard in the backseat and force sam to call him dad / daddy.
