I am looking for a specific age difference Kurt/Blaine fic where Blaine is 18 or close to it and Kurt is about 25. The gist of the story was Kurt lives in NYC and comes home to Lima to take care of Burt because he is undergoing cancer treatment. One day he goes in the Lima Bean where Blaine, and possibly Tina, works and Blaine is a smitten kitten. They, of course, get together.
Specific things I remember:
I remember there was a bit of an innocence kink going on because one of the plot points was them having sex in Kurt's old bedroom and it being Blaine's first time.
Kurt is only in Lima for three weeks and has to go back to work but is very worried about Burt's health.
Blaine and Burt have a heart-to-heart in the living room at one point, and I remember Burt being in a hospital bed set up in there for him.
I believe part of the resolution was Blaine telling Kurt he already had plans to go to college in NYC, so they could be together again there.
FOUND: I was mashing two stories together: Somewhere Along the Way I Missed You by missbeizy and Push by Jude Araya. See comments below for links.
