I'm searching for a specific Kurt/Blaine Slave fanfic. I think Kurt was a Designer in NY, and somehow Blaine came in his 'possession'. Kurt is against slavery and begins an anti-slavery campaign. He makes posters with the eyes of the slaves and a brief biography.
I think, Blaine was abused and assaulted by former owners, he's hurt when he comes to with Kurt. Kurt helps him and is very protective.
That's all I remember. I hope, one of you knows which story I'm talking about.
P.S. Found! I's "Def(inition)" by hedgerose
Thanks for the fast answer!
