So I'm looking for this specific fic in which Puck's in a band with Finn and Sam and they play at a gay club. Puck just got out of an abusive relationship with a guy called Justin, I think. Blaine dragged Kurt to the same bar.
Puck started singing accusing songs at Justin and when he tried to escape, Lauren held him in place. Puck then spotted Kurt looking absolutely adorable and asked him to play along. Puck started singing to Kurt and Kurt acted like his new boy-toy.
After they finished playing the first half or something Puck called the audience horny bastards or something. Sam told them to stop hitting on the drummer (Finn) because he was straight. Someone asked Sam "what about you?" & Sam actually enjoys all the attention.
I think Puck sang a song called Blue Eyes or something to Kurt.
They left together after the show.
