Sam/Dean, hair pulling kink (Sam's hair)

[kelios.livejournal.com]

I read a fic years ago, in which Sam gets off from having his hair pulled by Dean. I'm specifically looking for a fic in which Dean pulls Sam's hair while riding him. It's not the one by latentfunction/keysmash--that one is great but the one I'd like to read again doesn't have d/s overtones.

Any other recs you might have with hairpulling would also be appreciated!
