You MUST read this!
The Jungle Book by beadslut and jenna_thorn is a wonderful fast paced action adventure for Jensen and Jared. Replete with familiar characters and some of the best dialogue in the fandom. Iced with great art by smut slut.

Hell is Other People by Sasha-dragon will thrill you with its courageous Jensen who comes up with the best snark while being held prisoner by a true human monster. Jared and his pals are hunters who come to the rescue, although Jared may need rescuing right back. And Misha is simultaneously hilarious and creepy. The only drawback is that it's a WIP. But well worth the read and maybe if enough people poke sasha-dragon, it'll get finished.
