Chapter Text
Sam knows that Dean is going to be pissed at him for what he's about to do, but Dean’s scent is drenched in despair, and Sam can't take it anymore. Sam picks up the phone to call Gabriel, his friend and the owner of an exclusive Alpha agency. Gabe is the only one who won't ask questions or judge. Sam also hopes, selfishly, that if he gets an Alpha vetted by Gabriel, Dean will hate him less.
It isn't until after the call that the full weight of what he has just done hits Sam. He has placed an order for a strange Alpha to come and assist his brother through his Heat. It doesn't matter that Gabe assured Sam he was sending his best, his own brother, for Christ’s sake, or that this sort of thing happens all the time; Dean is still going to be, rightfully, upset at him. His brother is the kind of man who won't go to the doctor unless something is falling off, and even then, he'd probably still try to sew it back on himself first. Calling an Alpha in to assist with a Heat that Dean is only experiencing because of shitty, bootleg suppressants is definitely grounds for a fight.
Sam paces the wrap-around porch of Dean’s country home as he waits for Gabe’s brother, Cas, to show up. He thinks about how, in a civilized society, he'd be able to fix this with a trip to the pharmacy. Maybe if people hadn't been so fucking backwards for so long, modern medicine could have produced a pheromone replacement or… fuck, anything that would help. But Sam has known too many Omegas. He knows the only advice they're likely to get from a medical professional is to do what he's already done - call for an Alpha.
The acrid, pain-filled scent of Dean’s discomfort wafting out from under the door makes Sam’s stomach roll. He doesn't go to Dean; his familial Alpha scent won't be of any use, and he figures Dean would prefer only for a stranger to see him in whatever state he's in. Dean can send away Cas and never have to think about him again. That's a little more difficult with his own brother. Sam had been prepared to let Dean ride it out. Omegas frequently spend their heats alone, especially in this day and age! But Sam guesses that going so long without a heat, close to two decades, has probably messed something up that only spending a Heat with an Alpha can help.
Sam really hopes spending the Heat with an Alpha helps.
Gabriel’s flashy sports car, which Sam never cared to learn the make and model of, creeps up the drive fifteen minutes later. Sam knows whoever is behind the wheel had to haul ass to get here so quickly, and he's grateful. To his surprise, the stranger doesn't exit the driver's side of the vehicle when it stops. The large, dark-haired Alpha with an intense, blue-eyed gaze pours himself out of the passenger seat and leaves the door open as he walks towards Sam.
“Good evening, I am Castiel Novak, Gabriel's brother.” The stranger, Cas, holds out his hand to Sam.
“Sam Winchester. Uh, Dean's brother.” Sam shakes his hand. Sam is taken aback by the wave of calm that seems to radiate from Cas. It's not because the man is an Alpha; Sam’s also an Alpha, after all. There's something about the sheer presence of the man. As much as he hates to admit it, Sam often has to manually tell his body not to posture at other Alphas, especially when they get as close as Cas has. But here Sam is, with no urge to bare his teeth, despite standing between this stranger and his brother.
“Do you know anything beyond what I can smell?” Cas asks, looking calmer than Sam thinks he'd be in the same situation.
“Not really. He was coherent enough to tell me to ‘fuck off’ through the door an hour ago, but his scent is…” Sam gestures towards the door.
“Then I shall go inside and do my best to provide him some relief. Gabriel requests your company.” Cas mimics Sam’s gesture, but he points it towards the car.
This does make Sam bare his teeth. “I'm not going anywhere! What if…”
“I believe his intention is for you both to remain here in the car.” Cas doesn't make any move to answer Sam’s aggression. He also doesn't spell out why Sam may not want to be in the house while Cas goes about bringing his brother relief.
Sam deflates. He trusts Gabe, and Cas seems to be a professional. Dean would appreciate the privacy. It's going to be okay, he tells himself as he nods at Cas. He heads off towards Gabriel’s car.
Cas is distressed beyond belief. He doesn't even take on clients; he just happened to be having dinner at Gabriel's when Sam’s call came in. The only reason he is registered and up to date on all his tests is because Gabriel needed a legitimate first entry for his business before he could begin recruiting other clients. With their different last names, it looked as though Gabriel had successfully managed to convince an unrelated Alpha to work for him. Cas didn't see the big deal, but Gabriel had assured him that seeding the operation would convince Alphas that their dicks wouldn't fall off if they worked for an Omega.
Cas has to force himself to walk inside the modest home calmly. He wants to run to the distressed Omega so that he can fix whatever is causing his scent to sour, but he knows that will only scare the man he is here to help. Cas knows the moment the Omega, Dean, Gabriel had said, realizes that there is a strange Alpha in his house. Gabriel had yammered incessantly on their way over here about Dean, so Cas had expected an Omega growl.
The yearning howl makes Cas’ heart ache. Cas makes his way to the door, which is not hard to find; he just has to follow his nose, and knocks. This is where he gets the Omega growl from the other side of the door. If Cas were an asshole, he would just use his Alpha voice to tell Dean to calm down and let him do what he came here for. Cas is not an asshole. So, the knowledge that he might have to use his Alpha voice to keep the Omega from seriously hurting himself sits like lead in his stomach. He does his best to keep that out of his scent as he opens the door.
Cas is not immediately attacked, which he appreciates, but he is assaulted by the scent of distressed Omega. He made an error in assuming the room didn't have any scent-dampening based on how much was leaking out through the rest of the house. No wonder Sam was so worried. Cas is worried. He grabs onto the doorframe, letting the edge of it dig into his palm, to keep himself from rushing towards Dean. He counts to five in his head, then finally peers into the room.
The naked Omega, crumpled up on the bed, weakly growling, hissing and crying, is the most beautiful creature Cas has ever laid eyes on. The man’s green eyes are watery, his lips red and puffy, and his skin adorably freckled. The broad, 6ft frame would put off lesser Alphas, but Cas finds him sexy and solid. Cas’ traitorous Alpha-brain salivates at the sturdiness of him and how well he would be able to care for and protect his pups. Cas shakes his head to steady himself. This is not why he's here. He is here to help Dean, who hasn’t moved to either fight or present, which is concerning. Dean is just staring at him. He's even given up on the growling and hissing. Cas feels like he's being studied.
“Hello, I'm Castiel. I am from AlphaLand agency…” Cas starts but is cut off.
“Gabe,” Dean croaks.
“Yes, Gabe owns the…”
“No. Blood.”
Cas supposes it isn't totally out of the question for someone to be able to smell their relation, even if most people don't clock it. He's impressed with the nose on The Omega. He is not impressed with the way he can't seem to speak in full sentences. The situation is better than it could be, but it's still uncomfortable for Cas. It's getting more difficult to fight off his inner Alpha; the pain of the door frame against his hand can only do so much. The pained notes in Dean’s scent are off-putting, but underneath, there's still an Omega in Heat, naked, a few feet from him.
“May I enter your nest, Omega?” Cas asks, though it doesn't look like there was much of an attempt to make a nest. There just seems to be a couple of blankets and a few articles of clothing strewn around the bed. Still, Cas doesn’t want to be offensive.
The Omega starts growling again. Cas wonders why The Omega still continues to lie there. Dean doesn't seem to be making any moves to provide himself with relief. Perhaps he has already tried and given up? Cas has never heard of an Omega giving up like that before; usually, they keep attempting to alleviate themselves to the point of danger. Why doesn't the Omega stand up to fight Cas? That would be a more common reaction than this load of nothing that Dean is doing. Cas doesn't know what to do here.
“Yes,” The Omega growls.
Cas takes two steps into the room and closes the door. He turns back to Dean and begins to remove his coat, jacket, and shirt. Dean watches him the whole time and eventually stops growling when Cas reveals his naked chest. Cas wonders if the reason that Dean isn't fighting him is because Dean is actually fighting himself. Sam had said Dean was on suppressants for an alarming amount of time. Cas pauses in slipping off his shoes as he thinks about how humiliated an Omega would have to be to not try to relieve themselves.
Dean makes a dissatisfied noise that spurs Cas back into action. That's a good sign, right? Dean clearly understands that Cas is there to help, and isn’t keen on him dilly-dallying. The Omega makes a gorgeous, wanton sound when Cas shucks his pants and underwear, revealing his half-hard cock and burgeoning knot.
“I'm going to come over to the bed now,” Cas says soothingly. He waits a beat for the words to sink in before he does just that.
“Alpha,” Dean whines and makes his first move of the night - he flips up on his hands and knees and Presents.
Cas has to consciously keep walking towards the bed because he both wants to dive in and stop dead at the sight of Dean's chest on the mattress and ass up in the air. He'd been wrong about Dean not doing anything to make himself feel better. Cas can see the base of the plug in Dean’s red, puffy hole as he climbs on the bed. The poor Omega seems to have fucked himself raw. Cas will have to be careful. He places a hand in the center of Dean’s back to acclimatize him to touch, and the moment his hand makes contact, Dean pushes up into it with a pathetic sound.
“Oh, Omega. It's okay, you're okay. I'll make it better. Alpha is here,” Cas lets his Alpha-brain run his mouth on autopilot as he pets Dean and takes a closer look at his hole.
“Alpha?” It's clear Dean is still crying, even though Cas can't see his face.
“I'm here, Honey. I just wanted to make sure I wasn't going to hurt you worse. I'm going to remove the plug, okay?” Cas asks softly, like he's talking to a spooked animal. In a lot of ways, he is.
When Dean doesn't protest, Cas moves the hand not soothing across Dean's back to take hold of the base of the plug. He's surprised at the moan Dean makes and the way the Omega shoves his hips back. Cas slides his hand from Dean’s back down to his hip to hold the Omega steady, then gently begins to pull. It's bigger than Cas thought it would be, but it comes out easily. Cas sets it off to the side on a Metallica T-shirt.
The Alpha doesn't remember telling his hands to wander again, but they are smoothing over Dean’s beautiful freckled skin. Cas is trembling with the effort of not fucking Dean with wild abandon. Especially now that some of the more miserable tones of his scent have dissipated, leaving only an intoxicating sweet and spicy aroma.
“Are you ready for me to mount you, Omega?” Cas asks.
“Please,” Dean practically whispers.
Cas gives himself a stroke; he feels like he should need it with how upset he knows Dean must be, but the Heat scent has overtaken his concerns. He's hard as a rock. The Alpha lines himself up with the Omega’s hole, then pushes in gently. Cas' eyes roll in the back of his head as he slides into the tight, warm clutch of Dean's channel. Every instinct in him is screaming to FUCK this man and breed his Omega. He grunts and counts the vertebrae in Dean's spine as he drags his fingers along the length. It doesn't do much to quiet the Alpha in him, but it's enough to keep him from rutting mindlessly.
“Alpha!” Dean says loud enough that it startles Cas. He is reaching back for something, but Cas doesn't know what he wants or needs.
Cas gives Dean his hand, and the Omega pulls him down so Cas is blanketing Dean’s back.
“Alpha’s here, Omega. I'm going to take good care of you,” Cas assures as he bottoms out.
Tears are still spilling from the corner of Dean’s eye that's upturned towards Cas. The Alpha moves so that he can kiss the tear track as he pulls out of Dean, then makes his first thrust in. Dean makes a pleased trill, and Cas can't wait to get more noises like that out of him. With Cas’ face so close to Dean’s scent gland, the pleasured Omega scent easily drowns out any of the lingering pain and despair from earlier that still hangs around the room, and Cas feels like he's drunk on it.
“You smell so good, you're doing so well,” Cas praises and settles into a slow pace that will still get him off fairly quickly, but shouldn't make Dean too sore later.
“Scruff,” Dean grits out as he pushes back into Cas’ thrusts.
Cas sits up as little as possible to get a hand up to grip the back of Dean’s neck. He's more than happy to provide this extra bit of security and comfort to Dean, even if he is surprised at the Omega asking for such an intimate gesture. Cas wonders if it means Dean truly trusts him, or if Dean is just throwing things at the wall to see what sticks when it comes to feeling better.
The rumble in Cas’ chest comes unbidden. From Dean's scent and the high-pitched noises that he's begun to make, to his tight, fluttering hole, everything about The Omega is perfect to Cas. He knows he won't last long; he can already feel his knot inflating. Cas moves to sit up enough so he can snake an arm around to stroke Dean’s cock, but Dean whines, so Cas stops.
“I'm not leaving, Honey. I just want to touch you,” Cas explains breathlessly. “I want to help you come.”
Dean shakes his head as well as he can with his face in the mattress and scruffed. Cas doesn't fight him on it; Dean knows what he needs better than Cas does, and Cas is sure he wouldn't have been good at it anyway. He is struggling to keep track of his body. His brain is hazy with arousal, and each new lungful of Dean's sent scatters his thoughts even more.
Cas is battling his instincts to bite. He grits his teeth hard enough that he’s surprised his molars don't crack. Cas has never had such a hard time keeping his fangs in his mouth before.
“Alpha, knot,” Dean demands as he shoves back into Cas’ thrusts the best he can.
Cas creates a new sound when he laughs and groans at the same time.
“Soon, Honey,” Cas grits out. True to his word, Cas feels his knot grow too much to pull back out of Dean about a minute later. Cas rumbles in his chest again as his whole body screams at him to bite and breed while his knot fully inflates. After a handful of shallow thrusts, Cas snarls as his stomach flutters and his balls tighten. He shoots warm and wet into Dean, who gasps and moans as Cas’ knot stretches him to his limit.
“Yes!” Dean slurs.
Cas can't speak; he would slump forward if he wasn't already wrapped around Dean. He feels like his puppet strings have been cut. Cas musters up all of this strength and flips them on their sides. As soon as Cas settles his arm around Dean’s middle, Dean snatches it up and yanks until he can get Cas’ scent gland under his nose. Cas hums happily at the knowledge that his scent is desirable to Dean. He lets out a full-on satisfied Alpha rumble from deep in his chest when Dean begins to lick and suck at the scent gland. Sucking on a scent gland for comfort is usually reserved for children, but Cas is extremely pleased that his scent provides Dean comfort.
Cas’ nose is drawn to Dean’s scent gland in his neck like a moth to a flame, and he's a little embarrassed at the way he licks it without preamble. Maybe he's also seeking comfort. Or, maybe, Dean just happens to have the most enticing scent Cas has ever experienced, and he is attempting to drown himself in it.
“You're calm for an Alpha,” Dean observes after long, quiet minutes.
“Thank you?” Cas isn't sure how to respond.
“How?”
Cas thinks for a moment. “Would you like the Nice Version?”
“No,” Dean answers immediately.
Cas is quiet for a minute. “My mother hates Alphas…” Cas pauses, not believing that he's actually saying this, “I had to learn to be different.”
“Sorry,” Dean says softly, then kisses Cas’ hand.
“It's alright, I've adapted.” Cas kisses Dean’s shoulder. “Are you okay?” Cas changes the subject.
Dean shrugs. “Overwhelmed and freaking out.”
“That makes sense.” Cas has noticed that Dean is still only speaking in short sentences. “You're handling it well.” He doesn't know what else to say.
“Firefighter.” Dean shrugs again.
Ah, Cas thinks. Someone with such a demanding, public-facing job would need to be able to keep a lid on themselves. Add in that Dean is an Omega, and therefore unfairly judged, and suddenly Cas understands his extreme reaction. The poor Omega probably has a lot of practice shutting down. He kisses Dean's shoulder again.
Cas doesn't know how to tell Dean that he can relax. How does one tell another that they are a safe person? Cas ponders this as his knot finally deflates enough for him to slip out of Dean.
“Do you need anything before your next wave hits?” Cas steals another lungful of Dean's scent.
Dean starts to shake his head no, but stops himself. “Water?”
“I can get you water.” Cas plants another kiss on Dean’s shoulder, then gently extracts himself from Dean’s grip to stand up. “Would you like me to grab you something to eat while I'm in the kitchen?”
“Pie.”
Cas waits a moment for more instruction while trying to check Dean for injuries. Dean is hunched in on himself, and Cas gets no further direction, so he heads out towards the bathroom. He cleans himself up some, then searches for the kitchen. There, he finds a giant pack of water bottles on the counter, haphazardly torn open, and six or seven little gas station hostess fruit pies in a white plastic bag. Cas has a sneaking suspicion that he isn't going to find a lot of other food in the cabinets or fridge. He checks. He's right. The Alpha puts several water bottles in the plastic bag and leaves the room.
Cas brings his bounty into the bedroom, where Dean snatches the bag. Cas leaves him to his “meal” and rummages through his clothes for his phone. He sends a quick text to Gabriel to go shopping and pick up some actual groceries. Gabriel answers quicker than Cas thought he would. He had to hear a lot about his brother's attraction to Sam, so he assumed all of his focus would be on the tall Alpha. Gabriel surprises Cas again by being business-like and zero percent lewd. He figures that Gabriel must be more serious about Sam than he thought.
Cas looks up at Dean just as the Omega licks his thumb to clean off some artificial cherry goo. Cas swallows loudly. He had been so wrapped up in helping the Omega, he didn't pay much attention to how goddamn attractive Dean is. The Alpha scans the rest of Dean's body, even though he tells himself Dean probably doesn't want to be leered at.
Alarm bells sound off in Cas’ mind when his eyes get to Dean's cock. It's hard, which is enticing, but it also looks like it's been rubbed raw. It's no wonder he didn't want Cas to touch him earlier. Cas looks up at Dean's face and finds Dean staring back at him, the final bite of pastry halfway to his mouth.
“I…” Dean doesn't finish the sentence, and this face turns an adorable shade of red.
“Please finish your pie,” Cas asks. He makes his way over to sit on the edge of the bed near Dean's hip and watches, with Alpha satisfaction, as Dean chews and swallows his last bite.
“I would like to use my mouth on you,” Cas says as calmly as he can manage. “Healing Alpha saliva should be soothing regardless, but I would also like to attempt to provide you with an orgasm.”
Dean looks like a deer caught in headlights.
“Hey,” Cas says as he gently takes Dean's hand. “You have a choice. I won't do anything you don't want me to.”
“Why do you want to?” Dean sounds strangled.
Cas tilts his head and regards Dean. “Alpha saliva is meant to be used for healing…”
“Yeah, mating bites!” Dean cuts in.
“...And I wish to make you feel good,” Cas finishes. He HATES the prevailing idea that an Alpha doing anything to get an Omega off outside of a knot is a sign of weakness. Unfortunately, he's had to deal with hearing Alpha nonsense his whole life because he was born "part of the club.” Like that time he overheard a particularly stupid conversation where one Alpha told another that Omegas are less likely to get pregnant if they have an orgasm at all. That doesn't even make biological sense!
“Please,” Dean whispers, and it feels like a loaded gun.
Cas leans forward slowly, so he can telegraph his intention. He wants to share a kiss with Dean, but he isn't sure where Dean stands in the matter. Cas takes Dean moving in to close the gap faster as a good sign, but he can only hold on to that thought for a second. He's internally bowled over by how natural and right it feels to kiss Dean. They share a few long sipping kisses before Cas moves his lips to Dean’s jaw, then his neck. Cas wants to get his mouth on Dean before the Omega’s next Heat wave hits, but kissing him is incredibly addictive.
Cas stands up so he can reposition, and his heartbeat thunders in his ears when he sees Dean spread his bow legs. While he settles down between Dean’s thighs, Cas rains down kisses on every bit of the Omega he can reach. He takes pride in each little noise Dean makes.
“You smell so good,” Cas shares emphatically, just before he makes the first, gentle contact of his tongue to Dean’s abused flesh.
Dean whines loudly, and Cas stills, staring up at the Omega to gauge if it’s okay to continue. After he gets a little nod from Dean, Cas bends his head back down to softly lick another stripe just under the head of Dean's erection.
“I can feel it healing,” Dean says, almost to himself.
“Is it pleasant?” Cas asks and covers another inch with his tongue.
“Yeah… it's tingly.” Dean rolls his hips up, but stops himself partway through. “Not trying to rush you… I'll take it. Just grateful you're here.”
Cas is glad Dean seems to be speaking better, but he isn't a fan of the contents.
“Dean,” Cas moves so he can catch Dean's eyes. “You are not going to scare me off.”
Dean looks like he's been caught.
Details start to click into place for Cas. “Have you been making decisions to please me?” He swivels his head and kisses Dean's hip. “Possibly because you thought I would leave you alone like this if you didn't?”
Cas was wrong. Dean must not have looked caught earlier, because this is what feeling caught looks like. Dean is red, and his lips keep fluttering like he's going to say something, but nothing comes out.
“I would never leave you to handle this alone, Dean. Even if I did, I'd have to walk out past Gabriel, and he'd get someone else here. You are safe,” Cas says seriously and plants more kisses on Dean’s hip.
“Thank you,” Dean croaks.
“Thank me by asking for what you want.”
“Please use your mouth? Soft… like you were,” Dean’s voice sounds strained.
“Yeah, Honey, I can keep using my mouth,” Cas moves his mouth back over Dean’s cock. “Such a good Omega, asking so sweetly.” Cas delicately pulls Dean’s head into his warm, wet mouth.
Cas’ main goal is healing Dean’s skin first, so instead of sucking, he focuses on licking around the ridge of Dean's cockhead. Dean whines and makes little jerks of his hips that get more of his cock past Cas’ lips. Cas lets out a pleased hum and slides down gently so he can cradle all of Dean in his mouth.
“Alpha,” Dean pants and threads his fingers through Cas’ hair. Poor guy looks like he needs the lifeline.
Cas hums again and smiles at the gasp it gets out of Dean. The Heat scent is getting stronger; the Alpha knows Dean is going to need his knot again soon. He looks up at Dean and gently bobs his head to see if the Omega shows any signs of pain.
“Feels good, Alpha,” Dean groans when he catches Cas looking.
Cas continues on with his tender blowjob, humming around Dean, and drawing the most delicious noises out of the Omega. Why do other Alphas find this demeaning? It feels powerful to reduce Dean to a twitchy mess with just his mouth.
“Gonna come,” Dean says shortly after Cas dedicated his focus to soft swipes against Dean's leaking slit.
Cas hums an affirming noise and continues his motions on Dean's cockhead. He feels Dean jerk in his mouth, then bathe Cas' tongue in warm jets of come. The moan Cas lets out at Dean’s taste makes the Omega whine.
“Alpha!” Dean says pathetically as he shakes through his orgasm.
Cas pulls back from Dean when the Omega makes a pained noise. He checks Dean’s cock to find that his Alpha saliva did the job; the skin is much less inflamed.
“Alpha, I need…” Dean trails off.
“How do you want me, Omega?” Cas can smell what Dean needs, and his body is ready to provide it.
“I want to be on top,” Dean says, determined, but a little too quickly.
“Of course, Dean,” Cas crawls up the bed. “Such a good Omega,” Cas praises as he arranges pillows against the sturdy headboard. “I'm so proud of you for asking for what you want.” Cas continues.
Dean huffs and looks embarrassed as he straddles Cas’ hips. With a look of great concentration, Dean takes hold of Cas’ cock, positions himself, and seats himself fully on Cas. The Omega groans in satisfaction.
“Dean!” Cas wraps his arms around the Omega, overwhelmed already.
Dean leans in close to Cas and wraps his arms around the Alpha’s shoulders. He buries his face into Cas’ scent gland with a hum. Dean doesn't bounce on the Alpha’s cock, he grinds in Cas’ lap, and that seems to be enough for both of them.
“There you go, Honey, take what you need. You can have it.” Cas strokes and pets Dean everywhere he can reach. “Do you smell how good you make me feel? You're doing so well.” Cas can't stop himself from babbling. Something about Dean’s scent makes him feel as though he will simply perish if he can't tell Dean how good and perfect he is.
After a few minutes that feel like seconds and years, Cas feels his knot begin to fill out inside of Dean.
“Knot,” Dean whines.
“Not long now, Omega,” Cas promises as he adds his own hip movements to the mix and moves his hand down to gently stroke Dean’s cock. He relishes the moan that Dean lets out when he takes hold of him. There doesn't seem to be any more pain, and Cas is relieved.
Cas can see the edge, can almost taste his orgasm as he works with Dean for another minute or so. He's shaking, and his balls ache by the time his knot inflates. White starbursts explode behind his eyelids, and his heart thunders in his ears as he comes with a choked-off noise.
After a few moments, Cas comes back to Earth to focus on Dean, who sounds like he’s close.
“You’re okay, you can let go,” Cas slurs. A beat later, Dean whines and shoots off in Cas’ hand, covering it in thin Omega come. “There you go, Honey. So good for me."
Cas is spent, sated, and pleasantly drowning in the pleasured Omega scent. He licks Dean’s scent gland because he feels like he'll never get enough of it, and it has a paradoxical reaction of making it easier to not bite the Omega.
After a few seconds, enough fragments swim together for him to have a whole thought. Why does he want to claim Dean so badly?
“Mate,” Cas growls out loud the moment he thinks the word.
“You smell it too, huh?” Dean asks with a smile in his voice. Cas can't see his face; they’re both still buried in each other's scent glands.
“Mine,” Cas growls, and he's mortified. He's being gross and uncivilized!
Dean begins to purr.
Cas can’t believe his ears, but his hands can feel the rumble from deep inside the Omega’s chest, so it must be happening. It can be difficult to get any Omega to purr! Let alone one that was hissing and spitting at him not too long ago.
“Sorry,” Dean whispers.
“Please do not apologize for making such a beautiful sound,” Cas begs.
“How are you real?” Dean mumbles. If his mouth wasn't so close to Cas’ ear, the Alpha wouldn't have been able to understand it.
“Trauma, mostly,” Cas huffs a laugh. Dean chuckles.
“You could tell me about it over coffee?” Dean asks tentatively.
“Only if you tell me all the terrible things about you, too,” Cas counters.
“Deal.” Dean squeezes Cas with his whole body for a few seconds before relaxing into a puddle again. Then, he laughs.
“What's funny?” Cas asks.
“I just set up a first date with my Mate while his knot is in me.” Dean laughs.
Mate. Cas got distracted by Dean feeling comfortable enough to purr to think about it. There's no test or anything, but it's always been said that when True Mates meet each other, they just know. Cas knows.
“I'm sorry it's in that order,” Cas says.
“You're sorry?? I'm the one who has been using illegal suppressants for close to twenty years.”
Cas is glad that Dean is being more verbose, but again, he doesn't like the contents.
“It's often the only way to be treated like a person,” Cas spits. He always gets fired up about the way Omegas are treated, and it's probably going to get worse now.
Dean jerks his head up and kisses Cas so suddenly that it takes the Alpha a second to catch up and kiss back. They make out until Cas slips out of Dean, then they decide they need to shower before the next heat wave hits.
They make it three steps out of the bathroom before they start kissing again. Cas pulls back quickly because he hears a noise that doesn’t make sense. Someone is on the front porch. Before Cas can embarrassingly overreact, he hears Sam say something, too low for him to understand, then Gabriel giggling.
“What the hell are they doing?” Dean asks, ear cocked towards the door, like that will help him hear better.
“I told Gabriel to get groceries when I walked in your kitchen and all you had was plastic chemical water and fake pie.”
Dean sputters comically. “Hey, man, I don't come into your house and make fun of what you eat.”
“I'm certain you will, though.”
Dean laughs, and Cas beams at him.
His Mate.
