He could almost hear the mark whispering promises of him burning once more and how this time an angel wouldn't find him in time. Dean gritted his teeth and rubbed his hand over it. Everything inside him was screaming at him to hide it from everyone.

He never really said anything about the day. Didn't think it was that important. Just another day on the calendar. Another year gone full of violence and death and pain with a few fleeting moments of happiness. There was no reason to celebrate and no reason to even care aside from Sam's usual Happy Birthday Dean. But apparently no one had explained that to his angel.

But with grace flowing through him once more the angel found himself wishing for the chaotic emotions and experiences he'd suffered as a human. Anything to stop him from seeing the pain flaring through Dean Winchester's soul. (Coda for 9.10)

Ever since he was hired Dean has been finding ways to combine his class with Castiel Novak's. And it was getting harder and harder to hide the giant crush he'd accidentally developed on the other teacher. But he wasn't hiding it as well as he thought and now his students have noticed. Teacher!Dean, Teacher!Cas

Over the two years they had been going out Castiel had managed to buy a whole drawer worth of expensive, soft and silky panties for Dean. Some with lace. Some with bows. But all of them looked perfect on Dean. (warnings inside)

He just wants Cas. Just wants this whole thing to be done because he's been Cas's since the Alpha first laid eyes on him years ago when they were children. Dean had known that if he was ever going to have a mate, belong to an Alpha, it was going to be Cas. Cas who treated him like an equal, who stood too close to him and baked him pie for his birthday. (Alpha!Cas/Omega!Dean)

He needed the other cat. Wanted him because the Heat is flying through his veins. Dean wants Cas. Catboy!Cas/Catboy!Dean (warnings inside) Possible series..

Cas and Dean take their kids out trick or treating. The kids might be tired but their parents aren't. Dean stood several steps in their bedroom wearing the cowboy hat and a cocky smirk. It took seconds before Cas was crossing the room and pulling him into a kiss. Tongue pushing past Dean's lips and exploring his mouth "I love your costume." (warning inside: alpha/omega)

He has been forcing himself to stop touching his stomach around his family; from acknowledging that there is a life growing inside of him. Dean regularly covers his scent and doesn't bring any of his family back to his apartment. The same one he shares with his mate because Cas is his and he wants that for a little while longer. (Alpha!Cas/Omega!Dean)

Cas paused in the doorway watching Dean cooking. Breathing in the scents of food and home and mate. Everything filling him with calm and happiness as he allowed himself to focus more on Dean. On the green apron their daughter picked out and how Dean effortlessly moved around. His mate is humming under his breath. (Alpha!Cas/Omega!Dean)

There is only one who knows. That knows what he is and it's because the angel built him from the ground up. Had cradled Dean's soul in his grace and recreated the hunter's body. Atom by atom. Cell by cell. Knew every single part of Dean including what he was and had never treated him differently. Had kept the secret when Dean had asked him. Begged him. (Alpha!Cas/Omega!Dean)

Dean's been hiding what he really is for years. But all it takes is forgetting to take his suppressants once for his best friend to find out the truth. (Alpha!Cas/Omega!Dean)

Cas chose this room for the window. For the metal of the bed frame as he had secured Dean's wrists there and kept the other man from moving from his position. (D/S...more warnings inside)

He's the only one who has ever taken an angel mate, who has ever managed it, and Cas doesn't bother to hold back the feelings of dark pleasure at that knowledge. There had been a fight in the beginning but Cas always got what he wanted and he had wanted the golden winged submissive angel. Demon!Cas/Angel!Dean (Warnings: D/S...more inside)

At day 30 in Purgatory Dean's prayers to Cas get more creative and this time the angel actually reacts. (warnings: dirty praying, smut, grace sex, wings)

Dean notices that Cas needs something and he just wants to help. But he never expected this. Never expected to be pressed down into a mattress but he can't find it in himself to regret any of it. (future!cas/past!dean)

Dean never thought he would have this. That he would find such a strong mate. A dominant angel who he would want a nest with. One he could create a profound bond with and share his grace. Castiel was clearly the best choice. (angel!dean)

Dean realizes exactly why he's so upset. Why Cas finally getting laid isn't what he wanted. Why it is far from what he wanted. But it takes Cas for anything to actually happen and even then Dean is still stuck in his head. Written for a Prompt: How do you think a first kiss or realization (or declaration) of feelings would happen, in canon. (set in season nine somewhere)

He's sitting there staring at scraped palms and scuffed shoes. When he looks around he can't see souls. Can't see the dark weight of sin or the joy of life lighting them up. The hidden layers of life are no longer visible to him and he swallows around the pain. His wings are gone. His grace stolen. Everything is cold and hard and sharp.

Cas starts off drawing everything. Memories from the very beginning and stretching to the current moment. The drawings fill books. Detailed. Precise. Brilliantly colored and carefully put down onto paper. Snapshots of time. Things he found remarkable or interesting. Then he starts drawing something else. He fixates on it. Hands. Arms. A nose. Eyes. Freckles.

One of the first things Castiel noticed once he had fallen was how light he felt. And he hated it. His wings were gone. Stripped from him and he was grounded. So Cas did the only thing he could after his siblings stopped falling from the sky. He started walking. Forced himself to not focus on the lack of weight at his back. How he couldn't stretch his wings or tuck them close.

Dean is halfway asleep when he hears it for the first time. And he can't help but think he hallucinated the whole thing. Then two weeks later he hears it again in the dark as Cas wraps his arms around him and drags him close. Face nuzzling into the back of his neck as legs tangle together with his own.

Cas doesn't enjoy the extreme heat and he thinks Dean wears too many layers outside. Somehow this ends with Cas pressing Dean down into the grass and the hunter can't find himself complaining.

Dean had survived Purgatory. Been beaten to near death by Lucifer himself. After everything. All the fighting and struggling and surviving he was going to die at the hands of some nameless demon who had lucked out on finding him alone. Unprepared for a demon attack. He'd been searching for someone and his biggest regret right now was not finding him.

When Sam goes to pick up his brother and Cas he never expected them to be singing. Especially not that horrible song. They're stumbling drunk and leaning on each other...well within what Dean constantly refers to as "personal space" and Sam has a front row seat to everything.

Dean can't get it out of his head and the guilt is weighing him down. They left so much death and destruction behind them. It wasn't right and the image of Misha's body under that white cloth stained with blood kept haunting him. Giving up on sleep he wanders out into the dark parking lot and asks for help.

Dean can't help but feel smug the first time he hears the music coming from the bathroom even though he's half asleep. Clearly Cas has adopted his taste in music. It isn't until the third time he hears it coming from the bathroom that Dean realizes there is something...different about it.

Emmanuel struggles to remember who he was and where he came from. But there is one constant that tugs at his memory. It's green eyes, a bright soul and he finds pieces of his past in freckles on strangers, burgers and pies. And the voice that he can constantly hear...prayer to someone named Cas.

Cas finally gets Dean to agree to teach him how to cook...

Cas doesn't understand why Dean thinks Batman is better than Superman. After all Superman has powers...

Prayer is a sign of faith. Castiel has had nothing but faith when it comes to Dean Winchester since he pulled the hunter from Hell. But Dean isn't the only one who has been praying every day.

Now that Cas has fallen he can't simply wear the same trench coat and suit every single day. And Dean needs to have his own clothes. The fallen angel gets a bit of a 'hunter makeover' and Dean finds he enjoys this shopping trip a little more than Charlie's. Sam of course notices.

Once Cas had finally stumbled his way back to the bunker, cleaned up, ate something, slept and got some new clothes he was fine. No break down. No complaining about being a human. Nothing to indicate that he'd even cared about being an angel to begin with. He adapted. Learned. Fought. Hunted with them. Could out eat even Dean himself. He accepted no longer being an angel.

Castiel stood there looking around with wide eyes and surprise etched into his features. His sword moved slightly when he turned looking at something new, completely oblivious to the eyes staring at him or the whispers, clothes shifting with his movements. Showing off the lean lines that used to be hidden by a suit and trench coat.

He used to scoff when Sammy would talk about his witch. The 'connection' because how could what was essentially a stranger click everything into place? But Dean would die for Cas. And Cas would die for him. Familiar!Dean, Witch!Castiel

Reverse Verse: The musical sounds of the Host were a distant echo in Dean's mind as he moved away from the others, moving into a darker and more violent part of Hell, closer to the Pit. Closer to his brother long ago cast from Heaven along with his supporters and where he believed the Righteous Man was held. angel!dean, hunter!cas

Eve has been killed and Dean decides he could try with Lisa again. Castiel seems to have his own war and there is nothing Dean can do to help him. But months later Dean calls for his angel and Castiel is experiencing something he never expected. Jealousy.

(Different Choices Verse): After being knocked unconscious by his future self Dean Winchester makes a different decision. One Zachariah had not planned for.

A large hand reached out and stroked a few feathers eliciting a low moan from the angel whose eyes were now hooded. The demon moved his hands and the shirt covering the angel was gone revealing freckled skin. Castiel leaned forward placing a deceptively soft kiss between the angel's wings. Dean swayed on his feet and a chuckle escaped parted lips. "You like that...angel?"

When Dean had followed Cas' future version back to his cabin he hadn't expected this. Pressed against a wall, neck bared for warm lips and a talented tongue.

The Winchesters had sacrificed enough and to Castiel this was the only acceptable option. The gates of Hell would be closed and the Winchesters could finally have a chance. They deserved peace and he was going to grant it to them. No matter the price.

Castiel was never meant to survive the siege against Hell. He was never meant to be the one to find the Righteous Man and lay claim to the brightest soul he'd ever seen. Then again when it came to Dean Winchester nothing really went according to plan and the ex-angel found he had no complaints.

Some human experiences Castiel could honestly do without. And being forced to drink THAT was one of them...
