Fic where Brian really likes Justin's hair long

[bjshipper]

Hi all- I'm looking for a fic where Justin wants to cut his hair but he is hesitant to do so because he knows how much Brian likes it to be long. They end up having sex (surprise, surprise) where Brian really focuses on Justin's hair but after they finish he tells Justin he should do what he wants with his hair. Random- I know. Anybody recognize this one? Thanks in advance for your help!
