One is a fill to prompt in hobbit_kink (and seriously, that thing is hell lot of fun). Featuring Fili, devious plotting and emotional constipation on his part, and him pining after Kili. Yes, that's how low I get =] Can be read here in AO3 – Escape is a dish best served cold.
The other one is mostly around Bofur and his social insecurities, love life (Fili) and meddling younger brothers (Kili). Can also be found in AO3 – And then you substitute the hat for a crown.
And there's a complete Bofur/Fili fic, a little something I wrote for hobbit_kink. Can be found here, under the prompt, or in AO3 with spelling mistakes
Edit 23.04.14: I've started a third WIP, also Bofur/Fili. @ Hobbit Kink Meme, for this prompt. Don't know how to continue it yet, but I feel my muse is almost resurrected and my writing is almost back in full bloom. So it'll be interesting!
