Notes:

This is the first time in my life I tried to write smut, so if it’s awkward and weird I am sorry. I hope it is readable.:))

I recently started supernatural, I know it’s late, but better late then never, yeah?:) So I hope it’s not to out of character.

I would say this happens sometime in season eight.

I hope you enjoy it!

(See the end of the work for more notes.)

Work Text:


The air in the bunker was filled with a thick and fuming tension.

The trio had just gotten back from a somewhat successful case. ‘Somewhat’ because the monster they were hunting was dead, but it left Castiel in bad shape after a reckless decision on his part to make himself bait in order to save the victim. The plan worked, in the end. And Castiel survived, but that doesn’t make Dean any less angry.

Sam left them alone in the bunker, sensing the tension a mile away. He didn’t want to be involved in the argument they surly will have. 

„I can’t believe you.“ Dean finally spoke up, after he and Castiel are alone. „What were you thinking, Cas?!“

„Dean. I saved an innocent life, so I do not understand your anger. It’s what we do.“ Castiel looks at Dean a bit confused, he doesn’t understand, they do this all the time, so what’s the problem? Sure his grace is low right now, so he can’t heal himself, but thankfully the injury is not too bad. 

Deans face contorts into a mix of anger and concern.

 „You don't get it, do you?“ He steps closer, his voice dropping to a gentler tone. „It's not about the end result, Cas. It's about the process. You put yourself in unnecessary danger!“

„Like I said, Dean. We do this all the time, and I am an angel of the lord. I know how to ‚look after myself‘ as you would say.“ Castiel walks past Dean into the bunker. He doesn’t need to sleep or eat to regain his power and grace, but laying down sounds like a good idea to him. 

Dean follows Castiel into the bunker, his expression a blend of frustration and worry. 

„An angel of the Lord or not, you're not invincible, Cas. Your grace is low, and who knows what could've happened if that plan went south.“

Castiel starts to get irritated. After all, he did what he thought was right, and in the end, it worked just fine.

 „You are right, Dean, however it worked in our favor, so let’s not argue about something in the past.“ 

Dean crosses his arms over his chest. 

„Past or not, it's a pattern, Cas. You keep pulling these 'I'll be the bait' stunts, and sooner or later, it's going to bite you in the rear. And then what?“

Castiel is silent for a moment.

„Then so be it. It’s my duty to guard you and every other soul in need.“ He says honestly. „Dean, I- understand your worries, however they are unnecessary I can protect myself, low grace or not, do not waste your worry on me... I think I will rest in my room, so if you don’t need anything, you will find me there.“

Castiel would have wanted to fly to the room he calls his, but with his injured side and his low grace, he really can’t. If Castiel is honest with himself, he knows Dean was right, it was risky, he could have died, but that’s not important. No he wants to help as much as he can. He already bought chaos to this earth, the least he can do is to try to help and if he dies in the process, well… he wouldn’t feel bad about it. 

As Castiel turns to leave, Dean's voice stops him, a tinge of desperation creeping into his tone. 

Castiel, wait...“ He uncrosses his arms and steps closer, his expression softening. 

„You're right, it’s your duty. And we’re grateful.“

„Your welcome… I will always protect you and your brother.“  Castiel whispers in Dean's direction. Without another word, he goes to his room and closes the door silently after himself. Dean hesitates for a moment, then follows Castiel.

He softly opens the door, Castiel just closed. He watches Castiel lie down on the bed, his gaze flicking to his injured side. Dean's expression is pained, seeing his best friend hurt.

„Dean, it’s alright.“ Cas turns around to look Dean in the face. 

Dean always gives himself the fault, but it’s not, and Castiel wants him to know that.

Dean's eyes meet the angel’s, searching for the truth in them. He sighs, running a hand through his hair in frustration. 

„You're so damn stubborn, you know that?“ He sits down on the edge of the bed, his eyes lingering on the injury before looking back up at his friend. 

„I have learned from the best, after all.“ Castiel smiles shyly at his try to make a joke. He sees the hunter eyeing his injured side and sighs again. 

Dean.“ He says gravely.

He waits till Dean looks him in the eyes again and sits up. Castiel grimaces at the pain, but he doesn’t let it stop him. He grabs Dean's hand, as he saw him do the same with others sometimes. It seems to relax Dean.

„Dean. Listen, it’s not your fault. Do not beat yourself up about this.“ He says it as slowly as he can so the stubborn man in front of him gets what he is trying to tell him.

Dean's expression softens as Cas grabs his hand, and he looks at him with a mix of concern and affection. He listens intently to the words, his grip on Cas hand tightening slightly as he tries to process the words. 

„Cas, I... I feel responsible.“

Castiel stares at their hands. He is out of his depth here.

„Dean…“ He doesn’t know what to say. He is an angel of the lord, he normally doesn’t have these types of feelings and worries, but he knows he doesn’t want Dean to feel this way because of him.

Dean's thumb gently caresses the back of Cas hand as he speaks softly. 

„I know you're trying to protect me, to protect everyone. And that's... that's one of the things I admire most about you.“

„Ah, ahm- thank you, Dean.“ Castiel blushes slightly. Dean usually doesn’t compliment him, so he must really feel bad.

Dean gives his hand a gentle squeeze. 

„But, Cas... you're not invincible. And seeing you hurt... It's like a punch to the gut. You mean too much to me to risk yourself like that.“ He pauses, his eyes searching he angel‘s.

„I-“  Wow, Dean is never this honest about his feelings, so Castiel looks away. This is new. He blushes hardly.

Dean notices Cas sudden distraction and follows his gaze. He reaches out to gently tilt his chin up, forcing him to look at him. 

Cas, look at me.“ He whispers, his voice trembling slightly. „Please.“ He waits patiently for Cas to meet his gaze again.

The angel looks back at him. It’s hard for him. He knows, he must surly look as red as a tomato. 

„I also care deeply for you.“ Castiel whispers back. 

Dean's expression softens even more, a gentle smile tugging at his lips.

„I know.“ he murmurs. He leans forward slowly, giving Cas plenty of time to pull away if he wants to. His warm, gentle kiss presses against the angel’s lips like a silent promise.

Castiel is very still. He can’t believe it… Dean is kissing him! It feels so good, and his lips feel so soft.

Dean deepens the kiss, his arm wrapping around Castiels waist to pull him closer. He breaks the kiss only to press his forehead against the other, both of them breathing heavily. 

„I... I think I'm falling for you, Cas.“ He admits quietly, his eyes locked onto the blue ones.

Dean.“ Castiel says breathlessly. He looks away from the spying eyes to look at their hands, which are still locked together. He brings them upward. Dean watches as Cas brings their joint hands up, and he follows his lead as Cas places them over his heart.

Cas…“ He breathes, understanding the silent message. He looks into the ocean blue eyes, seeing the depth of emotion in them. 

„I'm yours, okay? All yours.“

„And I am yours too. Always was. Forever.“ Castiel smiles brightly at the hunter. He closes his eyes to feel this moment. It’s a beautiful and quiet moment with just the two of them. He never wants this to end. If the world ends tomorrow, then he will still be happy.

Dean's heart swells with love and happiness as he listens to Castiels words. He brings their hands up to his lips, pressing a soft kiss to Cas knuckles.

„Forever.“ He agrees, his voice filled with emotion. He wraps his arms around the angel, holding him tightly against his side. He rests his head on top of Cas, inhaling his scent deeply.

„I love you, Cas.“ He whispers, his voice shaking with emotion. He feels like he's floating on cloud nine, completely overwhelmed with happiness.

Castiel warps his arms around Deans neck. Snuggling against his collarbone. It feels like home.

„I love you, too.“ He says softly and slowly against his neck.

Dean tilts his head down, nuzzling against the hair of his loved one. 

„I know we have a lot to figure out. But we'll take this slow, okay? No need to rush anything.“ He wants to make sure they are both on the same page as they navigate this new relationship together.

Dean adjusts his position, scooping Cas up into his lap and holding him tightly against him, feeling like he's exactly where he's meant to be. Castiel leans back so he can look at the hunter's face again. His eyes go lower to the soft lips. He shyly leans forward to kiss Dean gently on his lips, just like they did seconds ago.

Dean smiles against Cas lips, his arms tightening around him as he returns the kiss. He deepens it slowly, taking his time to explore Cas mouth. He breaks the kiss only to press soft kisses along his jaw and neck, making Castiel giggle. 

„Tickles.“ Cas laughs softly.

Dean chuckles lowly, his hands splaying across Castiels back to support him. He continues to place soft, open-mouthed kisses along Cas neck, his scruff gently abrading the skin. He nips gently at the angel’s pulse point, making him gasp.

„Dean.“ Castiel moans, grabbing Deans hair tight between his fingers. Dean hums appreciatively against Cas skin, his hands roaming up and down his back soothingly. He nips and sucks at his neck, leaving his mark. 

Cas.“ He breathes, his voice hoarse with desire.

The angel looks down at him, looking at his lustful eyes. He is sure his eyes look the same. 

„I want more, Dean.“ He whispers down at him. It feels as if they are the only ones in this fucked up world.

„Are you sure?“ Dean asks, his voice gruff. „We can stop whenever you want.“ He wants to make sure they both are on the same page and that Cas is ready for this. For him. 

Castiel nods down at him. 

„I am sure.“ At Castiels words, Dean's eyes flash with hunger. He captures his lips in a searing kiss, pouring all his passion and love into it. His hands slide down to grip Cas hips, pulling him flush against him. He rolls his hips up, letting the angel feel his growing arousal. 

I need you, Cas.

Castiel moans loudly at Deans words. 

Then take me.“  He says breathlessly. 

Dean growls possessively, his hands tightening on Cas hips as he stands up, with Castiel in his arms, and turns around to toss him back on his bed.

„Dean.“ The angel gasps. He sits up with his elbows to look up at Dean, who stands there like a predator and Cas is his prey.

The hunter slowly unbuttons his shirt, his eyes never leaving Castiels. He tosses the shirt to the floor and begins to unbuckle his belt, his movements deliberate.

„Last chance to change your mind, Cas.“

Castiels eyes follow the movements. His pants feel uncomfortable tight.

„Dean.“ He shallows. „I need you, please. I can’t-“ he shallows again, blushing strongly.

Dean's face breaks into a predatory grin at the words. He unzips his jeans and lets them fall to the floor, stepping out of them. He stands before Cas in just his boxers, his arousal straining against the fabric.

He slowly crawls onto the bed, predatorily stalking towards Castiel. He grabs his ankles and pulls him down to lie flat on the bed, then begins to slowly peel off Castiels clothes, his touch gentle yet firm.

Every time he touches Cas it sends a shiver down Castiels spine, so he just lays there and lets Dean do all the work. He does want to do something, but this is all new to him. He doesn’t know what to do or what not to do, so he lets Dean take the lead. 

Dean takes his time exploring the body with his hands and mouth, mapping out every inch of Castiel. He seems to sense the angel’s nervousness and takes his time, murmuring reassurances.

„You're doing great, Cas. Just relax and let me take care of you.“ His voice is low and soothing.

„Hm.“ Castiel giggles and relaxes as Deans hands explore his torso. 

Dean slowly undresses Castiel. First the trench coat, then the shirt, till there is only the pants left. He leans down to press soft kisses along Cas collarbones and chest, his hands slowly trailing down his sides to the hips. He looks up at Castiel from beneath his lashes, his hands slowly sliding under the hem of his pants.

„Lift up for me, baby.“ His voice is low and gentle.

The angel does as told. He slowly lifts his butt, so it’s easier to take off the pants. Dean gently takes the pants and underwear off and throws them to his clothes somewhere on the floor. 

He takes a moment to admire the naked form in front of him, his eyes roaming appreciatively over every inch of exposed skin. He leans down to place a tender kiss on the left inner thigh, then the other. 

„You're so beautiful, Cas. I've never wanted anyone as much as I want you right now.“

I-“ Castiel doesn’t know what to say. He is overwhelmed with everything, Deans voice, his words, his touch. Everything. This is his first time, after all. 

Dean smiles softly, sensing Castiels overwhelming emotions. He leans up to capture his lips in a deep, passionate kiss, pouring all his feelings into it. His hand slowly trails up Cas thigh, teasing and caressing. He breaks the kiss to look into his eyes, then he gently lifts Cas legs, settling between his thighs. He looks up at Cas, his eyes filled with love and adoration. 

„I love you, Cas.“ He whispers before leaning down to press a gentle kiss to the entrance.

Castiel looks at Dean through his lashes. He tenses a bit as he feels lips against his entrance. He gasps at this new sensation. It’s weird. 

„Dean.“ He says, a bit unsure.

Dean pauses, looking up at Cas with concern. 

„Too much?“ His voice is soft, checking in with his angel. He rubs soothing circles on Cas thigh, patiently waiting for his response. He won't push him, no matter how much he wants the man in front of him, his comfort and consent are his top priorities.

„I don’t know how this works. It's all so new… I don’t want to disappoint you.“ Castiel looks sincerely up at Dean. He wants this. He does. He loves Dean so much it hurts. Dean always felt so far away, out of reach, and now he is here with him. Wanting him. It’s a bit scary. 

Dean's heart melts at the sweet words and innocent worries. He gently kisses Cas entrance again, this time adding a soft, teasing lick.

„You could never disappoint me, Cas. I'll teach you everything, and we'll figure it out together. Just relax and trust me, okay?“

„Ok, Dean.“

He smiles warmly at the angel’s trust in him. He takes his time, lavishing Cas most intimate area with gentle kisses and teasing licks, letting him get used to the new sensations. His hands caress the thighs and hips soothingly.

„You're doing so good, baby. Just feel good.“

Castiel starts to loosen up. He moans softly at the teasing licks and kisses. 

„De- Dean…“ He gasps and moans.

Dean can feel him relaxing more, so he intensifies his touch. His tongue pushes into Castiel, slowly pumping in and out, mimicking what he'll soon do with his fingers and then his hips. 

He adds a finger alongside his tongue, stretching Cas gently.

„Ah-„ Castiel shudders as Dean adds a finger. It’s a little painful, and it seems that Dean can see his face as it changes to a grimace, because Dean immediately pauses, lifting his head to look at Cas. 

„Babe? Talk to me. Does it hurt?“ His voice is gentle, his eyes filled with concern. He wipes his mouth with the back of his hand, waiting for Cas response. He won't push his angel if this is too much.

„It’s weird, but I want to keep going. Just…- I don’t- be gentle?“ Castiel says, unsure. He really does want to take this step with Dean.

Dean nods understandingly. 

„I will, baby. I promise. I'll go slow and stop if you need me to, okay?“

He, as gently as possible, pushes his finger in deeper. He croons soothing words, praising Castiels bravery and whispering sweet nothing's into Castiels skin, and it relaxes Cas greatly. 

The angel can feel the finger inside him, stretching his hole, and then, without warning, he feels a warmth around his length. He shockingly looks at Dean and sees him licking the head of his cock, said man looks up at Cas with a wicked grin, his mouth wrapped around the head of the angel’s erection. He pushes his finger deeper inside, as he bobs his head, taking more of the length into his warm, wet mouth. The dual sensations have Castiel moaning loudly, his fingers tangling in Deans hair.

Dean pushes another finger inside. He continues to suck Cas off with enthusiasm, his fingers stretching and scissoring inside, preparing him for his thickness. He can tell Cas is getting close, so he pulls off with a wet pop, chuckling at the mewled protest. 

„Not yet, baby.“

Cas breathes loudly, looking disappointed at Dean, but then Dean hits something inside him, that has him screaming and aching his back. He never felt this kind of pleasure. 

Dean smiles proudly at the sound of Castiels scream, knowing he just hit the angel’s prostate. He keeps his fingers inside, curling them to rub against that sensitive spot over and over. 

„That's it, baby, scream for me. Let me know how much you love it.“

Dean… Dean…“ Castiel babbles uncontrollably, feeling Dean hitting this place inside him again and again. He twists in the bedsheets.

Dean revels in the reactions he gets, his voice growing hoarse from encouraging the loud responses. 

„Come on, baby, beg for me. Tell me you need more.“ Dean slowly pulls his fingers out.

„More, Dean. More… please.“ Dean grins wickedly at the desperate pleas. 

„More what, baby? Tell me exactly what you need." While waiting for Castiels response, he takes off his boxers and rubs the head of his cock teasingly against Castiels entrance. 

„I want to hear you say it, Cas. Beg for my cock like the needy little thing you are.“ This Dean is new. Cas thinks he likes this new side of Dean. 

Please, Dean… I feel so empty. Give me your cock.“ Castiel breathes hoarsely. 

Dean's grin widens at Cas pleading, his eyes burning with a possessive hunger. 

„Fuck, Cas, you're so cute when you're desperate.“ He lines up his cock with Castiels entrance and slams inside in one brutal thrust, burying himself to the hilt.

Castiel screams. He reaches towards Dean, hugging him tight, moaning and gasping loudly against his ear.

„Dean. Dean.“ He just babbles his name over and over, being completely overwhelmed. Dean pants raggedly, staying still as he gives Cas time to adjust. He nuzzles into Cas neck, peppering soft kisses there. 

„You're doing so good, baby. Look at you, taking me so well.“ Dean's heart swells with affection. He slowly withdraws, only to thrust back inside, setting a steady rhythm. 

He watches the angel’s face closely, loving the way Cas eyes flutter shut, and his mouth falls open in a silent 'O.'

Castiel moves with Dean and lets him set the rhythm. He opens his eyes just a bit to look down where they both are connected, seeing his cock leaking pre come.

Dean's thrusts pick up speed. He hooks Cas leg over his shoulder, allowing him to go even deeper.

Fuck, Cas, you should see yourself right now.“ Dean's free hand reaches up to wipe the saliva from Castiels chin, his thumb stroking the lower lip. 

„So pretty when you're undone like this.“ He punctuates his words with hard, deep thrusts, his balls slapping against Cas ass with each stroke.

Castiel arches into his thrusts. He lifts his hands into Dean’s hair to grab it tightly, pulling the hunter towards himself. He greets him with his lips. It’s a wild and lustful kiss, more teeth than lips.

Dean growls approvingly against Cas mouth, his kisses becoming messier and more demanding as he loses control, his breathing becoming ragged and uncoordinated. 

Cas... gonna...“ With a final, shuddering thrust, he spills inside Castiel, his whole body convulsing with the force of his release. He nuzzles into  Castiels neck, panting.

As Cas feels Dean coming inside of him, he also lets out a final moan and comes too. After the high, he sags back against the bedsheets. His arms come loose from the tight hug he had Dean caged into and fall beside him. 

Dean stays buried inside for a long moment, his arms still wrapped tightly around his angel and his face buried in his neck. He's trying to calm his racing heart and catch his breath. 

Finally, he pulls out and settles beside Castiel, his arm curling around his waist to pull him close.

Cas lets Dean manhandle him, so he ends up laying on top of him, his head on the hunters' chest. He can hear the fast heartbeat slowly coming down. It lures Castiel to close his eyes and hum, satisfied.

Dean runs his fingers through Cas hair, his touch gentle and soothing.

„Sleep now, Cas. You're exhausted.“ He presses a soft kiss to his forehead, his arms wrapping possessively around the other man. 

Castiels injured side is long forgotten in the presence of their love, so he closes his eyes and lets himself drift away, feeling safe and loved.

Dean stays awake for a while, watching over his angel. He strokes the Cas hair, his face, just enjoying the feeling of having him in his arms. Eventually, his own exhaustion catches up with him, and he falls asleep, holding the love of his life tightly in his arms.

Notes:

I never knew how hard it can be to write smut and now I know, but it was a funny process, like I cringed soooo many times at my tries, it’s not even funny. But now! I have this work of art. Cough- cough-
