I am looking for this fic that I remember but cannot find: Kurt is a sub and Blaine a dom, and suddenly society decides that there will no longer be subs/doms. I remember that causes Kurt a lot of stress and he has to go in this 'subzone' (I don't know if it's the right word). I think he had to be blindfolded and such.
If anyone knows what I mean please let me know :)
Ooh and if there are more fics which have this subzone you can rec that too :)
(mods, I didn't know if I missed any tags?)
