Dean, Sam and you all were on a case together well at first it was just you three then another hunter showed up. The other hunter was a total douche, sure he helped get the job done but he still was plain out rude.

Dean and you weren’t dating, just occasionally hooked up, but stayed best friends.. you always were closer with Sam though considering Sam has always been your best friend since you met in college before Dean got him out. When Dean got him out of college you joined them thats how you became friends with Dean.

The other hunter didn’t know this though he just noticed how you were really close with both of them, sure he could tell Dean it was more romantic and Sam it was more platonic but that didn’t stop him from making a snarky comment to Dean when Dean pissed him off. The other hunter smirked before talking, “you walk around like you’re playing pro tennis only action you’ve seen lately is between your slvt girlfriends legs”

Dean immediately slammed the guy against a wall his eyes filled with rage, “don’t. ever. call. her. that.”
