I am looking for Puckurt future fic.
This is what I remember:
Puck is a teacher with his own Glee club.
The kids are unhappy with his choreography and want to hire someone to help them out.
Kurt is the star chereographer, married to Puck.
So Puck tells the kids he could get THE Kurt Hummel to help th club.
Ring any bells?
