Looking for a fic

[liz-104.livejournal.com]

I'm looking for a fic (maybe a drabble, I can't remember it) where Justin had the new haircut from S4 and Brian missed the long hair. He doesn't know what to get a hold on when they are fucking, until he starts playing with Justin's pubic hair. 

Thanks, and Happy New Year!

Found it! It's The change, by leelee2005, thanks again!
