Alpha! Canine! Dean and Omega! Feline! Castiel.

Holy. Crap. Has it seriously been a year since I've updated this thing? Damn. Heh, oops.

Enjoy!

Castiel scrambled down a steep slope, stumbling a little when he reached its bottom. From there he jumped the narrow stream that ran along the sandy valley and made for the nearest cluster of trees. The moon was full overhead, and while it would give him the advantage it would do the same for his pursuer.

As he sprinted up a gradual slope for denser cover the Omega fought to keep down the panic, to think rationally. It wasn't easy with adrenaline pumping through his veins, his instincts kicking into survival overdrive. He wasn't so far gone, but he'd slipped enough that he no longer cared that fear-scent would be tainting his trial. That whoever followed him would have a stronger line to track. He should be used to it by now, every Chase he thought for sure this would be the time he kept his head all through it.

But no, here he was in a near mad dash through the forest. Again. It would be something the Feline mourned over later, when he had the spare time. Now he had no such commodity. Perhaps it wouldn't be so bad, but he could hear their howls filling the air. Hear whimpers and cries and yelps as others fled or fell to the hunters that chased them. There weren't as many as there might be for a First Chase, but depending on the time of year Anniversary Chases could be just as full. Like many others of their kind the anniversary Castiel shared with his mate fell around the time of his heat. At least it being in early spring meant he didn't have to slog through ice and snow, nor did he have to run through a muggy night.

Hearing others fall to the Alphas that chased them made his ears quiver, but they stayed alert rather than press flat. They'd be no good to him otherwise. His tail was also holding strong, staying out for balance rather than hampering his legs by trying to tuck up. Though it did twitch uneasily every time he heard the howl of a Canine Alpha or caught the Canine yip of delight as another Omega fell. It was the one thing he could never quite get used to, being surrounded by Canines rather than other Felines. He liked living among his mate's people, but there was a natural comfort from being around one's kind, especially when you were down to bare instincts.

Castiel skirted a boulder twice as tall as he was, then began scanning the area as his chest began to ache, a stich making itself known in his side. He'd put up a good enough fight, surely. He'd come farther than he had last year, he could tell that much. Perhaps now if he could find a good tree to climb-

A breathless yelp was squeezed out of his lungs as someone collided with him, taking them both to the grassy ground. Instantly panic flooded his veins. Castiel sucked air back into his winded lungs and began to thrash as soon as he was sure nothing was broken. Bucking and twisting and writhing in the Alpha's hold, snapping when he felt a hand come too close to his mouth. When a familiar scent reached his nose Castiel only paused briefly, then bared his teeth and hissed in defiance.

In response a hand clamped over the back of his neck, pinning him to the ground. Another began yanking at his clothes, peeling running pants and boxers down his thighs, cool night air washing over his skin. Castiel yowled to the star-filled sky, trying desperately to shake the Alpha, with no luck. His ears finally flicked flat, tail curling uneasily. A growl thrummed in a chest pressed to his back, hands covered in calluses shoving his thighs apart so the Alpha could kneel between them. Fingers stroked his cleft, and a tiny, unwilling whimper was uttered as the Omega heard them come into contact with wetness.

There was that growl again, but now it was less threatening, more soothing. Castiel closed his eyes, letting the fight leak out of his body. An approving kiss was pressed to his neck, right before he felt the Alpha shift lower on his prone body. Warm lips brushed his hip, then the Feline gasped as a hot tongue ran up over one cheek, catching the edge of spreading slick.

The Omega whimpered, squirming as the taunting licks drew closer to his entrance. What was the point of cleaning up the slick now if it would just be produced tenfold before the night was out? But when he started shifting in the Canine's hold he was only rewarded with teeth sinking into one cheek, not enough to break skin but enough to make him yelp.

Reluctantly Castiel stilled, biting his lip as the licking resumed. Only when the Alpha was apparently satisfied did it stop, even giving the area he'd bitten a comforting nuzzle before crawling back over the Feline's quivering body. Rough cloth brushed the Omega's thighs as he did, the hand on his neck tightening as he stiffened again. The Canine was still fully dressed, though he could hear a zipper being opened behind him, a belt clinking.

A moment later both the Alpha's hands went to work, coiling his belt around Castiel's wrists. Again he began to struggle at the new development, only to be met with a warning growl pressed to his ear, a rock of hips against his own prone posterior. The Feline's shoulders hunched, but he stilled once more.

The Alpha finished his work, dipping his head to press kisses along his jaw and neck, a pleased rumble in his throat. Castiel lay still, eyes fluttering closed, as he felt the Alpha position himself. He tried to relax, but he still gasped when he felt the Canine enter him. Teeth sank into the mate mark on his neck, holding him steady as the Alpha bottomed out inside him, a pleased growl thrumming in his throat.

Castiel's mouth fell open in a silent cry as he pulled mostly out only to snap his hips forward again, fingers digging into his hips to hold him steady. The teeth still on his neck didn't break skin, but it wouldn't surprise him if that changed before the night was out. Depending on how much of a fight he put up the very territorial Alpha might decide it needed renewing.

For now, though, he was too busy enjoying the sensation of a hard, hot cock inside him. He'd never understood the appeal until he'd taken a mate of his own. A mate who, even in cases like this, had no intention of causing him harm. Was driving as much for the Omega's orgasm as his own, even though in a Chase the Alpha's climax was all that was really necessary. In order to secure a mate during a Chase they had to knot the Omega in question as well as bite them, mark them in scent and in flesh.

Castiel buried his face in the grass, a keening moan in his throat as a rough, rhythmic pace was set. It wasn't the same every Chase, he refused to make it easy for his mate and the Alpha wouldn't be nearly as satisfied if he did. He tried to make a different gambit each time, though with each passing year it was getting harder. The Feline decided to take it as a testament to his efforts that his mate had refused to risk turning him over to mate him, instead choosing to mount him so he'd be easier to restrain. Only twice in the last ten years had he been taken on his back during a Chase, and both times had been immediately following a pregnancy, when he hadn't yet returned to his physical best.

The Feline gasped as he felt the teeth in his neck bite down harder, the telltale sting of broken skin. He stiffened, wiggling a little in protest, not that it did him much good. In the back of his mind, in the little corner that would remain sane until he descended into full heat, the Omega felt more miffed than angry about the marks this would leave him with. The kits were getting old enough to ask questions.

A muffled, "Mine," was growled into his neck, fingers biting into his flesh as the Canine's grip tightened. "Mine."

Castiel's eyes rolled back, but in pleasure rather than irritation. This time. His mate had shifted his thrusts just enough to graze his prostate with each stroke. So rather than complain he only moaned in ecstasy, bucking into the thrusts, fingers gouging into the grass. He only squeaked in indignation when one hand released his hip to smack his ass hard enough to smart.

"Deeeeaaaan."

"Mine!"

"Yours! Now fuck me damnit!"

His mate bit him even harder, then began to move faster, rougher. Castiel cracked a faint smile, then let himself sink into the moment. It was primal, coarse, the sort of thing Omega rights activists liked to wail about, but he loved it, gods help him. But only because it was his mate.

Castiel felt it building, a keening whine in his throat as he clawed grass blades out by their roots. His Alpha's pace was starting to get erratic, a steady growl growing in his throat, a sure sign he wasn't far behind. The Omega whimpered needily, crooning his mate's name breathlessly, and was rewarded with a snarl in his ear. It registered a heartbeat before his orgasm crashed over him, taking his breath away for the second time that night. Spots danced under his half open lids, ecstasy rolling through every nerve. Two rough thrusts later his mate shuddered, bottoming out as his own climax made him tremble at the Omega's back. He didn't try to dislodge his mate, only whimpered as the mate mark on his neck was bitten through for a second time that night. Mmm, he must have truly worried Dean, if he was going through so much trouble to fortify his claim. He'd have to try a similar gambit next year.

Castiel let himself gradually float down from that wonderful cloud of bliss, eyes fluttering open as he felt better able to move. He tugged a bit at the belt still around his wrists, wondering if he could convince Dean to remove it. The Omega turned his head as his mate stirred, lifting up off him, dislodging his teeth. His knot would remain for a while still, and when he shifted the Feline couldn't help but moan.

A pleased growl thrummed at the sound, the Canine nuzzling his shoulder. Castiel sighed, then raised his hands as much as he could without moving anything else and asked, "Mate? Take it off now?"

Rather than answer right away, a hand came up to stroke his hair. Castiel gradually let himself relax, for all he knew what was coming. When he was about to start purring again the hand fisted in his black hair, pinning his cheek to the grass as his mate bent to rumble in his flattened ear.

"Wait. When you're mine completely once more, then I'll release it. Mine."

"And you are mine," Castiel reminded him patiently.

Rather than object, as some Alphas did this deep in their instincts, Dean began stroking his hair again, touch gentle. Castiel laid his head down, enjoying the ministrations as much as he was everything else. Not for the first time he wondered if it was because he was a Feline, that his mate worried so. Canines mated for life, unless one died or there were serious issues. Alphas and Omegas didn't often pertain to the marriage concept Betas practiced, but then Castiel often thought they needed the social contract in order to feel properly bound to their mates. While they rarely married, Alpha and Omega Canines were bound for life regardless once they decided to settle down with a life mate. Felines tended to be more flexible in that regard, often only staying together if their union produced kits or if they were especially fond of each other.

Castiel rolled his hips, making both of them moan. Dean kissed the back of his neck, nuzzling his soft ears, breath starting to come in pants again. Smiling faintly, Castiel kept going. Stimulating the overly sensitive knot buried inside him, using it to massage his own prostate until they both fell over that edge a second time.

As his mate fell limp over him, panting into his shoulder, Castiel wondered if it wasn't a combination of things that had his Alpha particularly possessive this year. The species difference might hold some part of it, he was still sure. He'd never leave Dean, but then his Alpha could be a bit insecure at times. Hence the yearly need to reaffirm that Castiel was in fact his. The Omega's ability to stay so far ahead in this year's anniversary Chase probably hadn't helped. But at a guess most of it was something else. Something they'd been discussing prior to this.

Well before setting foot on the Chase grounds, Castiel had stopped taking his birth control. They'd decided to round things out at three, then stop for good. Right now they had Henry and Ben, and Castiel was hoping for a girl this time. Henry was the eldest at nine, and Ben had recently turned five. This heat they would try for number three, a daughter if Castiel got his wish. He adored his boys, wouldn't trade them for anything, but there was still that wish for one more. Dean had, naturally, been very enthusiastic about helping to fulfil that wish. Personally Castiel had never understood why some of his own kind had considered it something to tolerate, having an Alpha around. But then Felines didn't always get quite as attached to their offspring's other parent as Canine's did. Frankly Castiel wasn't sure they knew how much they were missing.

Castiel only stirred when he felt the Alpha's knot start to deflate. He lifted his head, propping himself up on his elbows as Dean gingerly separated from him. When he looked up into the Canine's face he could still see thick, Alpha-red glinting in normally evergreen eyes. A soft, low growl thrummed in the Canine's chest as he dipped his head, nuzzling his Omega's cheek, lips brushing his ear. Castiel smiled shyly, a purr starting up in his own throat at the ministrations. It was official, he couldn't get anymore marked than he was now. Dean's scent would be saturating him by now, his knot and their strenuous activities had made sure of that. It also reinforced the mark marring Castiel's neck, the cum that would soon start to drip from him. He'd been chased down and caught by the Alpha's skill alone, nothing else. He'd been won, fair and square, simple as that. Technically he could still reject the Alpha, but he wouldn't. Dean had yet to give him reason to. Even other Felines would be reluctant to change mates this late in the game, considering Dean had already sired both of his kits thus far. But while most of his kind would regard him with a range of emotions from bafflement to ridicule, he loved Dean. The Canine was his best friend as well as his lover, a life partner he cared for deeply. Not to mention he was a wonderful father to their kits.

"Alpha?"

"Mmm?"

"Should we head back now?"

Dean seemed to consider this, then his ears flicked upright. They twitched, his head tilting, eyes glazing over briefly. Castiel held perfectly still with bated breath, his own ears jerking upright and swiveling to find the cause of his mate's unease. It didn't take him long to find it. When he did, a coy smile curled at his lips. He'd never be this bold on any other day, but his instincts were still spiked.

Someone was nearby, and getting closer. It only sounded to be a single individual, and they were creeping along, so he guessed it to be one of those who wandered a Chase grounds for one of two reasons. To swoop in on Omegas who were still alone or had rejected their Alpha, or to simply watch. Despite the security a few always got through. There was even a branch of porn dedicated solely to Chases for pity's sake. While he enjoyed them in the moment Castiel had rarely been tempted to look in from the outside, particularly after he'd met Dean. These were such intimate moments, it seemed too invasive.

Now, though, it sent a thrill up his spine. Knowing someone was watching, knowing they'd see what was done under the moon's silvery light. It made warmth curl anew in his belly.

Tilting his head, Castiel brushed his lips along his Alpha's jaw as he purred, "Claim me again, mate. Breed me, mark me, make me cum while they watch us. Let them see what you do to me."

The spike in arousal was so strong Castiel could smell it in seconds, the scent making him moan. Dean dipped down, kissing him so passionately his tail curled. When he drew away both were gasping again.

"You serious?" the Canine rasped, nuzzling his ear.

"I wouldn't have asked otherwise," Castiel chided lightly. Though he understood the confusion. He'd never displayed exhibitionistic tendencies before.

"You're fucken' awesome, you know that?" he growled in lowered tones, flipping the Omega onto his back.

"I know," Castiel purred, arching up to kiss him, hooking his bound hands over the Alpha's head as he did.

"He's here," Dean murmured, lips brushing his ear.

"So give him a good show."

Castiel arched up, lightly flicking the tip of his tongue over his mate's lips. Dean answered with a growl, and another kiss that was more punishing than gentle. He caught the Feline's lower lip between his teeth as he parted, earning a mewl from his mate.

"You're mine," the Canine snarled, raking his teeth over the still bloody mark, one hand palming the Omega's chest. Fingers grasped a nipple, twisting it roughly, making him gasp. Then they slid farther south, digging into one ass cheek before giving it a slap. "Mine to keep, mine to fuck."

"Please!" the Feline mewled, bucking his hips meaningfully. "Please, Alpha, fuck me. Need you to fuck me now, while I'm at my most fertile. Already given me two kits, please give me another."

That alone earned him another wash of Alpha instincts and a second tail-curling kiss. "Was gonna do that anyway. Can't wait to see you all swollen and pregnant with my seed again."

Castiel mewled, head falling back, panting up at the moon as Dean slithered down his body. He left a trail of harsh nips and light kisses as he went, only stopping when he reached the Omega's throbbing cock and drooling hole. He grasped his cheeks in both hands, prying them apart to study his work thus far.

When he ran his tongue up the Omega's hole and up his taint Castiel bucked, gasping, at the sensation. He writhed where he lay, hands clamping on his hips to hold him steady as a hot tongue probed his fucked entrance, lapping cum and slick alike. Just when Castiel thought he was going to have another orgasm Dean withdrew, leaving the Feline to whimper in dismay.

Crawling back over him, pushing one knee up to his chest, the Alpha growled, "Want to be sure. Not gonna let you walk outta here until you're seeded proper."

The Omega's rapid nod was cut off in a rough, dominating kiss. He could taste himself on his mate's lips, his tongue, as his own was devoured. He still clung to his mate with bound hands, leg hooking around his waist, head falling back with a moan as Dean slid into him.

"Oh gods," he whimpered breathlessly. "Again, Alpha? Already…still sore from last time."

"Too damn bad," was the growled response, accompanied by the sharp snap of his hips. "You want a kit? Wanna see if you can bear me a daughter this time?"

"Yes, please, please mate," the Omega pleaded, gasping out the words between thrusts.

"Then stop bitching and take what you're given."

Back and forth they went, bantering far more than usual as they moved together. That tiny, sane corner of Castiel's brain knew very well this would likely be humiliating to think back on, but damn if it wasn't fun right now. Despite the dirty talk, it was as close to making love as was physically possible when heat instincts and rut instincts were this active. By the end of it all Dean's fingers were laced through Castiel's, both his legs hooked around his Alpha in an attempt to cling to him, panting and swollen lips kissing breathlessly. It was messy and sloppy and oh gods he loved it.

Castiel had no idea how much time had passed, and honestly he couldn't bring himself to care. As it was, it wasn't until Dean's second knot had swollen inside him, tying them together, that he was coherent enough to start real communication. He leaned up a little to murmur in one pricked forward ear, "Is he still there?" He was very sure their watcher was indeed still hovering behind some brush, he could hear the heavy breathing, smell traces of aroused male Beta Canine on the wind, but he knew his Alpha would be more aware of such things than he. After all, Alpha instincts were geared towards prevision and protection, they would be more honed, on high alert knowing there was someone there while an Omega was being mated and bred.

"Yeah," Dean rasped back, lips ticking the Feline's ear.

"What should we do now?" He too kept his voice low, just loud enough for his mate to hear. Not loud enough for their watcher.

"If he's recording, I ain't letting that get out."

"Catch him?"

"Yeah."

Giving the hand still laced with his own a squeeze, Castiel murmured, "Want to see them. Need to be sure it's not being streamed off-site before you deal with him."

He felt his mate's lips curl into a proud smile against his temple. "Good call. I will bring him to you for judgement."

Castiel smiled himself, arching up a bit to purr, "Thank you, Alpha."

Plan made, they settled down to wait, knowing full well the separation was considered part of the show. Castiel was content beneath his mate, exchanging lazy kisses, practically purring where he lay. Canine's didn't purr, but there was a soft rumble in his throat that Castiel had decided was the rough equivalent. He liked hearing it, especially now.

When his knot did deflate, Dean didn't withdraw right away. He pressed a soft kiss to the Omega's forehead, then untangled their fingers to unbuckle the belt still binding the Feline's wrists. Castiel sighed softly as it came away, drawing his arms down, blinking lazily up at his mate. "Thank you, mate."

The Canine bent to kiss his lips, then slowly pulled out. Castiel's breath hitched at the sensation, lids fluttering, gazing up at Dean as he drew himself to hands and knees. He pulled up his pants, getting everything tucked away and secured before moving to the side, pulling Castiel into a sitting position. The Omega mewled softly, shifting onto his hip, clutching his mate's hand.

A crooked finger tipped up his chin, their lips brushing tougher tenderly.

"Still there," Dean breathed.

"Good. May I see him?"

"'Course, Cas. Wait here."

After one last kiss, Dean rocked to his feet, then trotted into the nearest cluster of trees. Castiel laid back down, stretching languidly on his back, arching on the ground, a maneuver he knew by Dean's past reactions got no small amount of attention. He bit his lip, rolling his hips, humming a little before drawing himself upright. He was in the process of getting his own clothes into place when he heard a yelp, followed immediately by a snarl and a rustle of brush. Smiling, he rolled onto his hip again, watching as the brush rattled violently. His mate was an excellent hunter.

Less than a minute later, Dean stalked out of the brush, dragging a shorter and pudgier Canine with him, belt looped around his neck in a noose. He was hauled by said belt, stumbling and lurching along until he was six feet from the Omega, at which point his legs were knocked out from under him. He stared, eyes wide and bulging, at the Feline cocking a head at him, sitting on his hip, legs tucked up.

"I suppose this is what I should have expected," he mused, tail twitching lazily behind him.

"Please," the Beta managed to wheeze, clawing at the belt. He opened his mouth to say more, but it was choked off as the belt was yanked tighter.

"Don't speak to my mate," Dean warned, voice a growl. He fished something from a pocket, tossing it to the Feline.

Castiel caught it, turning over the device. He'd expected a phone, not an actual video camera. At least this kind it was easy to see if it was streaming to another device, which it wasn't.

"Don't!" the Beta managed to squeak out, one hand flailing free to strain at the Omega as he stopped the recording. "You'll break it!"

Dean yanked him back, not that he'd gotten close to the Omega anyway, a warning growl in his throat. Leaning down, he rumbled, "Shut up. 'Sides, if he breaks it it'll be 'cause he means to."

Castiel paused his work to smile briefly up at his mate. Numbers and tech had always made more sense to him than people, and prior to becoming a stay at home parent he'd worked in I.T. development. He still kept up with tech, so he could go back to work once all the kits were old enough, and because he found it fun. Dean was no slouch himself, he worked in R&D for Roman Industries, but in some things he still deferred to his Omega.

"It's not streaming," he announced, opening the side door and popping out the chip. Holding it up, he said, "This is all there is, mate."

Dean grunted, yanking the still struggling Beta back in line. "Awesome. Want me to take care of it?" he asked, ignoring the strangled squeak of protest from his captive.

The Omega pursed his lips, considering. "Perhaps. But I'd like to see what it looks like first. We've never recorded ourselves before."

"What about the camera?"

"If we give it back he'll probably go right back to it. But if we take it that might slow him down. Henry's been wanting one, anyway." Their eldest was entering something of a videographer phase. "We take the camera and chip, then give him to the Chase officials," he decided, carefully standing.

"Sounds good to me. On your feet." He hauled the Beta upright, then gave him a shove. "March."

"You're gonna let an Omega order you around?" the other Canine protested.

Dean growled at that, effectively shutting up the irritating Beta. Even so, he still added, "All you see is what you like to jerk off to. Freaks like you don't care about anything else. There's more to it than that."

While he did agree, wholeheartedly, Castiel's instincts were still running a bit high. It was unbelievably hot, watching his mate manhandle a Beta, acting all protective and authoritative. He was too sore for more right now, not to mention Dean himself would have that irritating refractory period. Perhaps tomorrow night he could express his delight properly.

In an effort to divert his own attention, Castiel looked over the camera more thoroughly as they walked along. The camera itself was a newer model, he noticed. In good nick, too, for all he wanted to thoroughly disinfect it before giving it to his kit. Particularly since the quality of the camera was as good as confirmation this particular mouth breather sold what he recorded.

"How long have you been selling videos like this?" he asked abruptly.

"First time," the Beta wheezed, having worked his fingers under the belt to spare his throat a bit.

"Don't lie to him," Dean warned.

"Oh come on, at least let me have the camera back. It's bad enough you took the whole chip. Do you have any idea how rare it is to see a Canine mounting a Feline in the wild?"

Castiel's eyes narrowed, even as Dean slammed his charge against the nearest tree, a warning growl in his throat. Still, he knew that if Dean did serious harm to the idiotic Beta he would be kept overnight until the authorities were sure his instincts wouldn't make him a threat to himself or others. That wouldn't do.

"Say one more word, pervy douche bag, I dare you," the Alpha was snarling, eyes flaring red. "Say one more fucking thing."

"Dean?" Castiel pressed himself to his mate's back, leaning up to nuzzle his ear with a soft whine. Lowering his voice, he murmured, "You promised the boys you'd take them to the Lego store tomorrow, and to the park, and for ice cream. A whole day. You can't do that if you're locked away. Please?"

Gradually, he felt the tension leave his mate. He still had to maintain a good grip on the Beta, but he did ease up, yanking him away from the tree and hauling him along with the warning, "One more word out of you, and I'm ripping your fucking tongue out."

Castiel smiled, pleased, and meandered along in his Alpha's wake. No, he had absolutely no cause to change mates. He loved this one. Even if he didn't, Dean was an excellent provider, an excellent protector, a wonderful lover, a best friend, and a wonderful father. Life did happen, but when at all possible he never broke a promise to their kits. He doted on them, really, spending time with them when he could, caving even faster than the Omega when they begged for sweets or a toy. That wasn't to say he wasn't firm, if fair. A good balance in Castiel's opinion. As best he could tell, Dean's eagerness in getting him pregnant again was as much due to the notion of having another kit as it was the sex. Though whether it was a daughter or another son he didn't seem to care.

The Omega watched mutely as their captive was tossed into the official's hands at the Chase's start. The guards gave the still instinct-high Alpha and his hard-won Omega a wide birth, letting them head towards the parking lot without stopping them. Particularly after Dean bit out what the man had been doing.

Castiel nuzzled his mate's neck as an arm was draped around his shoulders, purring quietly. Mmm, it might very well be worth the invasion of their privacy, he decided. Besides, after this many years some excitement was surprisingly nice. Perhaps tomorrow night they could watch the video, see what they looked like from the outside. If it went well, they'd have to do so again, if from the privacy of their own bedroom, thank you very much.
