Dean/John pretend to be couple fics

[fic-obsessed.livejournal.com]

Hi guys! General search here. There's so many fics about Dean and Sam or Dean and Cas pretending to be a couple, but I've NEVER read one where Dean and John do.

It doesn't have to lead to a relationship or anything, it can be totally gen, but I'd love to read a fic where Dean and John have to pretend to be a couple for a hunt or something, and the awkwardness that goes with that.

**Please nothing underage (not that it'd really fit this request anyway) especially if there is some slash in the fic, but other than that, I'm good.
**Also, bonus points if Sam finds out about them having to pretend, and laughs his ass off, and mocks them for ages about it. (Along the lines of "Did you kiss him?" when Bobby made a deal with Crowley, that kinda thing.)

Thanks guys, you're the best.
