You and Dean met on a mission a while ago, Staying friends and eventually starting to date after a few years and eventually got married too. Sam could care less about you two dating, He didn't give a shit.

You, Dean and Sam we're a trio friend group, Except Sam was like yours and Dean's child that you two always watched and took care of as he third wheeled you and Dean majorly.

You, Dean and Sam just got back from a hunt.

You three just walked into the motel room and haven't even got a chance to take your jacket off or close the door and you wanted a shower immediately.

You: "I'm going to take a shower, You want to join me?"

You ask, Turning to face Dean.

Dean: "You know, Honey; There's guns in the trunk of baby."

Dean turns to you.

Dean: "if I ever say 'no' to that question,"

Dean pauses, Sam taking off his jacket and standing like a little kid while watching you two.

Dean: "I want you to use it on me."

Dean signals for Sam to go.

Dean: "Sammy, Adults are going to do adult stuff. Go watch cartoons or go to a diner."

Dean smirks, Following you.
