Looking for a specific fic where blaine and kurt have a daddy/little relationship where kurt has regressed full time to the point where we wears diapers 24/7!
There's a time where they have to go back to Lima for something (I think it was Burt and carols anniversary party) which they have avoided for years due to how regressed kurt is!
There's a scene on the flight to Lima where kurt have to change his own pull up in the plane bathroom which he's really proud of himself when he does it all on his own!
When back in Lima his friends and family grow concerned that blaine is abusing him because Rachel asks if blaine has ever hit him and kurt says yes but he means only a spanking when he's been bratty. Everyone tried to keep blaine away from him and kurt is calling for his 'daddy' which Burt thinks is him!
In the end they have to explain their relationship! Can't remember much else but if someone knows the fic I'd love to read it again!
