OK so I’ve read a good few, but these particular ones stuck with me. I feel like sharing them here and I will definitely add more and flesh this list out a bit more as I find more :)
I’m Just a Love Machine
PG - 13Summary: The Impala finally gets the chance to love Dean back. The problem is, Castiel seems to be in its way.
Not Usually a Good Thing
Summary: Five ways Castiel made Dean feel.
Summary: There was not a dream that Castiel did not know, except this one.
Jump The Track
Summary: High school AU. It’s Dean’s senior year at Lawrence High, and he’s already given up on himself. It takes the arrival of the strange, intense, awkward Castiel Delacroix at the school to prove to Dean that maybe his life is worth saving after all.
Summary: AU: Loosely based on Grimm’s Cinderella. Once upon a time, a merchant’s wife gave birth to a little boy named Castiel, who was perfect in all ways, right down to the beautiful black wings sprouting out of his back. However, in a country still fighting the phobia of human-to-animal shapeshifters, not everyone agrees, and when his mother dies, Castiel is left at the hands of his stepfather Zachariah, who doesn’t condone non-human traits despite being part-bird himself. And then there’s Dean, the only friend Castiel has in the world, who thinks Castiel’s wings are awesome, but is hiding a few problems of his own.
Summary: College AU: Dean’s life at twenty-four makes him feel like he’s forty—he works two jobs to help pay bills for his house and put his genius little brother through private school, and has spent six years (on and off, let’s be honest) working on his mechanical engineering degree at KU. With so much of his life devoted to his family, Dean has little time in his schedule for class and no time for social interaction. Then, while getting his classes together for the fall, he finds himself in a do-or-die situation: He must take his last literature class now, his spring already filled with those left for his major…except that none of the English classes will fit his schedule.
Sing and I will hear you
Summary: AU: Castiel is cursed to be a kitten every day of his life (a small, gray cat, very cute and fluffy) from 4am to 8pm sharp until he finds his true love. Dean finds him one day after a group of teenagers were basically torturing the poor thing. He takes care of him (and he’s hurt real bad) but Castiel runs away to transform when Dean leaves him unattended. During the night, Dean finds Castiel in human form, still weak and weary from what happened to him in kitty form.
Dean always thought of himself as more of a dog-man…kittens were for girls.
Summary: AU: When Sam Winchester prays for his brother, Castiel is finally sent on his very first assignment. But what should be a simple love match turns into much more and Castiel finds himself risking everything to ensure the happiness of his extremely frustrating charge.
In Real Life
Summary: AU:High school teachers. Castiel is the English teacher at the school Sam teaches history at. Dean is a writer who has been sending his stories to an online friend (Castiel) for editing. Sam finds out and realizes that Dean and Castiel don’t know each other in real life, but really should.
Summary: Dean never really gave Castiel’s wings much thought, but he didn’t let himself think about Cas’ mouth much either.
