Hello! Can you rec me some really good sebklaine fic where all three are in love with each other? Thank you!
This is not a trope that we normally read, although I do have two fic recs below.
I did a search on AO3 and there are 122 fics tagged with Blaine Anderson/Kurt Hummel/Sebastian Smythe.
There is also a website called SebKlaine.net that has 705 stories that feature SebKlaine, Kurtbastian, or Seblaine.
Stray From What You Are by sparrow30
The Kingdom of Aldern has always been ruled by a magical guardian of royal heritage, and their non-royal political consort. When Dominant political advisor Sebastian Smythe hears from his submissive Blaine Anderson that Crown Prince Kurt Hummel has begun his search for a consort, he sees a perfect opportunity for a bit of social climbing - and if he gets a piece of royal ass in the process then so much the better.
Unfortunately Sebastian forgot to read the small-print; there's a lot more to this union than simple politics, and soon he finds himself on the outskirts of a budding relationship between Kurt and Blaine. If he's not careful he's going to lose everything he's ever worked for, and his submissive to boot.
But maybe, if he plays his cards right, he'll win something better than he ever imagined possible.

When they stumble upon a talented, humble piano player named Blaine, however, everything begins to change. - GKM fill
