After Hours - A Klaine Fanfic

Kurt, despite his goals for the future, has somehow landed himself back at Mckinley. As a teacher, no less. He's independent, making a decent living, and somewhat over Blaine Anderson. Or, at least, that's what he thought up until the ex-History teacher ex-fiance shows up in his workplace after hours, drunk off his ass and that much hornier. He wants to give him and Kurt - Klaine - another shot at working out. He wants them to be more than the occasional booty call. Can they make this work once more? Or will both of their less flattering traits picked up over the years send their relationship spiraling back down the drain?
