Season 1 Fic.

[http://users.livejournal.com/_alicesprings/]

For the life of me I cannot remember the name of the fic where Justin's obsessed with brushing his teeth. It's by one of my favourite writers I'm sure, yet I have gone completely brain dead and can't think of it. Help!

It's a bit prOny, and it has Justin running off to brush his teeth before bed, and Brian being amused that Justin can put his tongue up someone's ass, but gets grossed out by not flossing. And just to piss him off, he kisses Justin with his smoky, dirty mouth after he's brushed.
