I'm looking for a Puck/Kurt fic where Kurt is with Blaine who keeps falling asleep before getting Kurt off. Puck steps in and the fic ends with Puck sending Blaine a text about taking better care of his boyfriends. It was on a lj post (or possibly insanejournal) and the song was Not Fair, interspersed between the plot.
Sorry there's not much, it wasn't the longest fic and I read it ages ago.
Thanks for any help!
