Work Text:
Snow drifts down and the wind wipes across Dean’s face. A full body shiver goes through him. He grits his teeth, reaching up and hoisting himself up to the next ledge. He’s only got a little more ways to go before he finds his destination.
This is the first job he doesn’t feel good about. There’s a real chance he won’t make it out alive, but even so, he took it, knowing this one job can set him and Sammy up for life.
He’s hunting a dragon.
The town below this mountain has been dealing with having a dragon as a neighbor for years and they’ve finally pooled their money together in order to hire a proper monster hunter. They’ve dealt with burned crops, stolen animals, and restless weather because apparently just a dragon’s presence is enough to fuck with localized weather. They’re nasty son’s of bitches, but Dean still took the job.
Dean’s never encountered a dragon before. Sure, he’s researched the hell out of them and looked through more books than he cared to admit, but seeing on in real life? That sounds like a dream come true if it weren’t for the whole having to kill it thing. Dean’s always found them oddly beautiful. He might even call them majestic. They’re big and shiny and strong. Maybe in a different life he’d even wish he was born a dragon instead of a monster hunter.
His heart stutters in his chest as he hears something above his head. Movement. The dragon’s lair is obviously ahead. He can’t slow down. He needs to get his head on straight. One wrong move and his life could end up on this mountain.
Dean finishes his climb, finally stepping onto solid, flat ground. There’s an opening to what he can only describe as a cave in front of him. Moving slowly and as quietly as possible, Dean moves forward. He pulls his blade, keeping it steady in his hand, ready for anything.
There’s shuffling and he braces himself.
He’s expecting an ancient dragon. In his reading, he’s learned that an ancient dragon can grow to the size of a house. What he finds instead, if a dragon that’s a bit bigger than a horse.
Dean freezes, his eyes widening as the dragon runs from deep within the cave towards him. His heart picks up speed, his hands shake, and his body tenses. He needs to fight, but for the first time since he was a young boy, he freezes.
The dragon barrels towards him but comes to an abrupt halt once he’s in front of Dean. They stare at each other, his green eyes meeting crystal blue. Dean suddenly feels lost. The dragon is beautiful . He’s never seen anything so beautiful in his entire life.
The dragon has shimmering blue scales with black spikes that run down their spine. They’re bigger than Dean, but Dean still thinks he can take it. This isn’t the biggest monster he’s ever had to deal with.
But is this a monster? There’s intelligence behind those beautiful blue eyes. The dragon watches him, just as intently as Dean is watching them.
The dragon takes a step forward and Dean is still frozen in place. He stares as the dragon’s nose flares wide, breathing Dean in. Their eyes dilate, their pupils blown wide.
A nose bumps into his chest, sniffing him, taking deep breaths. It tickles and makes Dean’s stomach swoop almost violently. Now that the dragon is this close, Dean’s body loosens enough for him to bring his hand up, touching the haunch of the dragon. No one is more surprised than Dean when it’s the hand not holding his blade.
The scales are pleasantly cool against his fingers, impossibly hard yet pliable at the same time. He feels inexplicably drawn towards this creature. His fingers grope the scale, feeling all the way around it before moving up, towards the creature’s face.
The dragon stays completely still, their eyes still wide as he watches Dean explore. When his fingers touch the dragon’s nose, a shiver runs through them both, like maybe the spot is extra sensitive. The dragon opens his mouth, showing off his sharp teeth. Dean sucks in a sharp breath, preparing himself for the worst but instead, the dragon licks his fingers, his tongue huge and wet and warm.
Dean doesn’t know what the fuck is happening right now. He just let a fucking dragon lick him and instead of being terrified, he’s weirdly horny?
The dragon raises their front paw, shoving Dean down. He lets out a grunt as his back hits the ground. The dragon follows him down, his chest leaning down against Dean and pining him against the ground. Their nose presses against his neck and Dean is powerless to do anything but let the dragon do exactly what it wants.
Swallowing thickly, Dean realizes with a start that he wouldn’t mind giving in. Who else could say they fucked a dragon and lived to tell the tale? He’d be a fucking legend. Literally.
That huge tongue presses against the underside of Dean’s throat, covering his cheek. His body heats all over and a groan escapes him without his permission. The dragon’s lower body moves, pressing the two of them together. Dean can feel a long, huge appendage press against him. Apparently the dragon is a boy.
Holy. Fucking. Shit.
The dragon presses his cock against him, rutting against Dean’s leg as he presses his tongue against Dean’s face and throat, over and over. Dean feels himself growing hard in his jeans. He’s not sure if he should be horrified, embarrassed, or a mixture of both. Instead, all he feels is turned the hell on.
“Son of a bitch,” he gasps out and the sound of his voice seems to startle the dragon.
He huffs through his nose, smoke blurring against Dean’s face. The dragon quickly moves away from Dean. Before Dean can stop him or say a single word, the dragon flaps his wings and takes off down the mountainside, leaving Dean laying there all alone.
“Fuck,” he breathes out, running a hand through his hair which is slick with the dragon’s spit. When he said he could take the dragon, he meant in a fucking fight .“Fuck!”
Dean stands up, looking around. What the fuck is he supposed to do now?
After getting his breathing under control and his heart to calm the fuck down, Dean walks further into the cave. He keeps going until he finds where the dragon has made his home.
If Dean was a smart man, he’d get the fuck out of here. He’d turn around and get back to the town below the mountain as quickly as he could. The dragon will be back and it would be better for them both if Dean was nowhere near here.
He decides to look around instead.
The first room he finds is a very stereotypical dragon’s lair. There are chests filled with gold and gems and other various treasures. If Dean could only take a bag full of this stuff, he’d be set. He walks further into the lair.
The next room he finds is a standard kitchen which is weird because what does a dragon need a kitchen for? They burn their food with their fire breath. Further in, he finds a bedroom with a little table, shelves of books, and a bed.
This just keeps getting weirder and weirder.
Dean sits on the bed, picking up the journal on the bedside table. His eyes skim over the words which are written in beautiful script. Whoever wrote this, has beautiful penmanship.
Dean’s heart picks up speed, his chest fluttering. Apparently, the dragon he just met is the youngest of three. The real problem in the area is his brothers, Michael and Lucifer. They fight and they plunder and they care nothing for human affairs. The only thing keeping them at bay, is the blue eyed dragon.
Affection that Dean can’t explain, fills him, warming him all over. He doesn’t even know how a dragon can write, yet he’s hanging on every single word written. The longer he reads, the more compelled he feels. He needs to meet this dragon properly. He needs to get to know him properly. He needs-- his face heats as he thinks about how it felt to have the dragon over him before.
Dean is so caught up in reading that he doesn’t hear the dragon until he’s in the room with him.
Startled, Dean looks up, his eyes widening in surprise. For the second time today, this dragon leaves him surprised.
“Hello,” the dragon says, his voice deliciously deep and gruff. He’s standing on two feet and looking far more human than earlier. Yet, he’s unmistakingly not human. There are scales across his face and down his chest, his eyes too big for the rest of his face, his nose bridge too wide.
He’s just as beautiful in this form as the other.
Dean does his best to remember he needs air to live instead of just choking on his tongue. He lifts his hand. “Umm, hi.” Then he realizes he’s been caught snooping. He quickly puts the journal back with a wince. “Sorry about that.”
“It’s alright. I don’t mind.”
“You don’t?”
“No. Whatever is mine is yours. You may have anything your heart desires.”
Dean’s brows wrinkle. “And what do you get?”
The dragon tilts his head to the side, looking like a confused bird. Dean really shouldn’t find it adorable, but dammit, he does.
“I get my mate, of course.”
Dean chokes on his own spit. “What? Your mate? Me? No, that can’t be right, man.”
“Castiel. Not man. I’m a dragon.”
“I know that you’re a dragon. What’s Castiel mean?”
“That is my name. Castiel.”
“Right,” Dean says slowly. “I’m Dean.” He’s in a dragon’s lair, with a dragon standing before him, telling him that he’s his mate and Dean is so fucked because the only thing he can think about is the fact that he’s in the dragon’s bed right now. He’s got fucked up priorities.
Castiel steps towards him and Dean’s heart picks up speed, pounding against his ribs. His fingers find the sheets, digging in and holding on tight. Castiel watches him like a predator watches his prey. Dean wants to be caught.
As Castiel steps between his thighs and falls to his knees, Dean’s head spins. He stares down into Castiel’s blue eyes, feeling somehow lost and found at the same time.
“Tell me to stop, and I will,” Castiel says, his fingers touching Dean’s thighs, slowly sliding up. “Tell me to stop, Dean.”
Dean bites his bottom lips, saying nothing. He doesn’t want this to stop. He never wants this to stop.
Castiel pulls his jeans open, his palm wrapping around his cock and pulling it free from his pants. Dean hadn’t even realized he was so hard until right now. He moans, low at the back of his throat.
“Beautiful,” Castiel says before nosing against his cock, breathing in his musk. “Beautiful but I want more, Dean. Can I have more of you? Please?”
Dean feels breathless. “Yes,” he says, his voice coming out shaky. “Yeah, Cas. You can have whatever you want.”
Cas gives him a toothy grin before standing up and grabbing Dean by the hips, flipping him over. His feet are on the floor, his chest pressed against the bed. His entire body feels on fire, desire nipping at his belly.
Dean’s had his fair share of one night stands but this somehow feels so much different, so much better. He doesn’t know if it’s because he’s about to fuck a dragon or because it’s Cas.
“Stunning,” Cas breathes out and Dean shivers, feeling hot breath against his ass. A startled moan leaves his lips as that tongue he’d felt against his face now brushes between his cheeks.
“Oh my god,” Dean hisses out through clenched teeth.
“Relax for me,” Cas says, running his teeth against the swell of Dean’s ass cheek. “Relax and I’ll make you feel so good, Dean.”
Dean clenches the sheets, closing his eyes as pleasure rushes through him. Cas’ tongue runs over his ass, over and over and over again until he finally starts to relax. Once he does, that talented tongue points, pushing into his body. It’s like nothing he’s ever felt before.
“Fuck, Cas. Fuck. So good. More. I need more.”
Cas pushes a finger beside his dexterous tongue, opening Dean up, giving him everything he craves. If this form is anything like the one Dean met earlier, he needs to be ready to feel the biggest cock he’s ever felt before. Fuck, he needs it more than he needs the air he’s breathing.
Dean floats endlessly on a cloud of pleasure. Castiel eats him out and fingers him open while Dean moans and squirms below him. Everything is too much yet not enough at the same time. He needs, needs, needs.
Sweat drips down his spine and his body tenses over and over. Every time he’s close to coming on Cas’ fingers, Cas pulls back, leaving him to whine. He praises Dean constantly, his voice grounding him in the moment.
“Please,” Dean finally says, his body more than ready for what’s to come. “Please, Cas. Need you.”
Cas finally pulls away from his ass, giving his cheek one last kiss. Strong hands grip his hips, flipping him over onto his back. Cas pulls his pants off completely before standing between his open thighs.
Dean’s eyes land on Cas’ cock and he groans, his eyes closing as he keeps himself from coming on the spot. His cock is so fucking big. Even with all the prep they just did, Dean’s not sure it’s going to fit.
The tip is slightly tapered before growing thicker below the head. It’s the same blue as the rest of his scales, the sides appearing slightly ridged. God, it’s going to feel so fucking good when he finally gets it into himself.
“You are incredible,” Cas says, his voice making Dean shutter. “I’m going to have you now. You’re going to take every last inch of me and I’m going to make you mine.”
“Yes,” Dean says right away with a nod. “Cas, yes .”
Cas wraps his hands around Dean’s thighs, tugging him forward until his ass is hanging off the side of the bed. He pushes his hips forward, running his cock against Dean’s hip, letting them both see just how big Cas’ cock really is.
Jesus fucking Christ. How the hell is he going to take all of that?
Before he can question how exactly this is going to work, Castiel is pushing the tapered tip into Dean’s ass.
“Fuck, Cas,” he gasps out. Cas is so fucking hot , scorching his insides. It feels so fucking good and somehow makes him relax enough to take more of him.
The stretch is all consuming. Dean can’t think, can’t speak, can do nothing but lay there and let Cas push forward.
“So good,” Cas says. “So fucking good. Look at you take it all. Look at the way you’re stretching open wide just for me. Mine. You’re all mine, Dean.”
Cas pulls back until just the head is in his ass before pushing forward again, feeding just a little more of his cock into Dean’s body. He does that over and over, pulling almost all the way out before pushing more into him.
The stretch is borderline too much but every time he thinks he needs to ask Cas to stop, he pulls back, leaving him aching for more. He’s not sure how long they continue doing this but eventually, Dean looks down at his stomach, seeing the tiniest bulge below his belly button as Cas’ hips touch his.
“You’ve taken all of me,” Cas breathes out, his face filled with wonder. “You’re perfect. The perfect glove for my cock. You were made to hang off my dick, Dean.”
Dean whines, his ass clenching around Cas. His hand goes to his dick, a blur as he strokes himself. Cas begins to move, slowly fucking into him with gentle strokes.
“Cas!”
“Go on. Make yourself come from my cock, Dean. Let me see how much you love the way I fuck you.”
Dean cries out as his body locks up. Lightning bolts of pleasure rushes through him as he comes, covering his stomach with his cum. A moment later, Cas is letting out a growl, his cock somehow becoming impossibly hard and hot inside of him. He feels the way he’s unloading inside his ass and he fucking loves it. Before he gets too full, Cas pulls out, the rest of his cum mixing with Dean’s on his stomach.
He’s completely boneless as he lays there, covered in cum and sweat. He closes his eyes, trying to get his breathing under control.
Gentle fingers touch his chin and Dean’s eyes snap open. Cas leans over his body, smiling softly. They just fucked nasty and they haven’t even kissed yet. Apparently, Cas is thinking the same thing.
“Can I kiss you?”
Dean chuckles. “You just fucked my brains out. I think we’re past you asking for kisses, Cas.”
“Even so, may I?”
Despite everything, it’s this that makes Dean blush. The gentle care, the soft inquiry. Dean feels himself falling.
“Yeah, Cas, you can kiss me.”
Chapped, supple lips press against his own and Dean is lost. His head swims, his body warms, and he’s struck with longing like nothing he’s felt before.
“Oh,” he breathes out. They pull back but don’t go far, their foreheads resting against each other. “I was sent here to kill you.”
Cas nods. “And now?”
“Now, I’d really like to do that again and maybe figure out this whole mate thing together?”
Cas kisses his cheek. “Whatever you want, Dean. You’re my treasure now and I plan on doing everything in my power to keep you.”
There’s so much Dean has to figure out, but for now, he’s content to climb into Cas’ bed fully and spend the night curled up with the dragon who’s apparently his mate.
