Shout out to Voided Evolution, FIREmizuchi, Katlover98, Tiddo-mus, heaoffir, and tottally-anonymous-person! Reviews are my fuel and my fix! :)

Ask and thou shalt receive, my pretties! Okay, honestly, may have vaguely considered adding to this, but it was still an experiment. (Chase Me is my first story outside the Hetalia genre.) But it's surprisingly popular, both here and on AO3. Reviewers on both sites requested a sequel, preferably with smutt and/or sex.

Note: There will be a part three! No guarantee's on delivery, because life's a bitch and adulting is tough, but it will come! :)

Enjoy!

Castiel hadn't flown so fast in a long time. His heart pounded in his chest, the wind whipping through his hair and blasting his face. It was, in a word, exhilarating. He could see why they'd chosen this form of mating ritual, way back when. It was one thing to know it got your instincts revving to go, it was another to experience it.

Flying hard and fast was exhilarating enough, but with an Alpha on your tail? Knowing that once you were caught you would be mated? When he'd first heard of it, Castiel had been uneasy, fearful even. Gradually, as time had gone by, he'd started wishing for it. Now the thought of being caught and claimed sent a surge of delighted anticipation through him. Not that he'd give in so easily, of course. If this Alpha, Dean, wanted him, he'd have to work for it.

Castiel plunged into another cloud, doing a sharp turn and changing course once the vapor hid him from view. When he shot out again, Dean was emerging from a different part of the cloud, and he'd gained a little bit of ground. Laughing in delight, Castiel tucked his black wings to his back, deciding to see if he could keep that newfound distance. He plunged like a stone, dropping towards the ground below. Only when he was just short of crashing did he spread his wings, leveling out and swooping over a lake. He glanced back in time to see Dean pull up a little higher off the water than he had, grinning widely as he continued his pursuit.

The Omega swooped over the lake, climbing higher to fly over the tops of a grown in forest. He was starting to tire, but the Alpha would be too, right? They'd been flying full speed for-

Castiel yelped as something crashed into his back, knocking his wings out of rhythm. He was startled to feel a pair of arms wrapping around him, his wings giving out as the Alpha put all his weight on him. At first he was horrified the were going to crash, but Dean spread his own wings as they started to drop, gliding them into a small clearing with surprising ease.

The Omega stumbled as they landed, but before he could try to run again Dean was on him, shoving him back against a tree and attacking his mouth. Castiel imminently relaxed, clinging to him, returning the kiss eagerly. He was surprised by how much he genuinely wanted this, wanted this Alpha to claim him, make him his own.

Apparently the feeling was mutual. Dean wasted no time in yanking the trench coat from his shoulders before shedding his own jacket, fumbling for their clothes. Castiel, noting with annoyance that human clothes took more effort to escape, fumbled for the Alpha's jeans when Dean pulled away just long enough to peel the shirt over his head. Then those hands were jerking at the soft material of his own clothes, getting them off the Omega with remarkable ease.

It took a minute, but after pulling away to wrench off the heavy footgear he was able to shed the jeans, finally just as naked as Castiel. Rather than stop to admire the Alpha, putting that aside for later, the Omega all but jumped him. Hands in his hair, clinging to his neck and shoulders, wings giving a strong half flap so he could hook both legs around his waist as he kissed the Alpha eagerly.

This bit of initiation was enough to kick Dean's Alpha instincts into gear. Castiel soon found himself dumped against the hill for his troubles, the Alpha on top of him in a heartbeat, one hand pinning his wrists in the grass above his head as his mouth was claimed in a dominating kiss. He gave in with a whimper, returning it where he could, but didn't struggle against the hold. Maybe if he stayed down Dean would hurry up and mate him already.

As if reading his mind, the Alpha used his free hand to grab his hip, hitching it up a little, nudging his thighs farther apart. Castiel hooked his legs around his waist obligingly, gasping when they parted for air. It was then he noticed with a shiver of delight Dean's instincts were in high gear, if not by scent then by his eyes. He couldn't see any of that pretty, jade green anymore, only black. He knew his own eyes must look the same, but it was good to know Dean was in much the same state as he was. It meant there was reciprocation, unmasked mutual attraction.

There was maybe two seconds after Dean had pulled away from the kiss, when Castiel was still panting for breath, before he took the chance to give the Omega exactly what he wanted. Castiel's eyes flew wide, a surprised, pleasured gasp escaping his lips as the Alpha drove into him. A tremble ran through every limb, including his wings, making him shutter. Holy grace, it hurt, but it still felt amazing. Was that right? He knew Gabriel had frolicked down below with the humans, but he hadn't ever felt the urge. Was this normal, or was it because he'd never done this before?

Dean didn't give him the chance to ponder it much. Soon he was too busy to give anything else besides the here and now any thought. Dean, for his part, seemed to be quite good at this. It was all he could do to keep up, if you could call it that. Clumsy returned kisses, fumbled touches, and various vocalizations that were mostly unintelligible were all he could manage.

The Alpha had let go of his wrists once he'd first entered him, but Castiel still wasn't entirely sure what to do with his hands. Suddenly he wished he'd taken Gabriel's advice and ventured into the more risqué forms of entertainment. Maybe not the film stuff, but even written porn would have been better than nothing. He knew he should do more than just lay here, but what was he supposed to do?

Trembling fingers clung to muscled shoulders, combed through short cut dark blond hair, ran up his chest and stomach, feeling the planes of lightly tanned skin. Whenever the Alpha dipped down to recapture his mouth, he tried to return it as best he could, but he never felt like what he did was right. He never actually intended to say anything, either. That just happened. An embarrassing variety of whimpers, half cries, and even a giggle left his lips before he could stop them. Were you supposed to laugh during sex? He'd been mortified initially, but a pleased rumble had thrummed in his Alpha's chest, and the next kiss had an upturned mouth.

Castiel was so busy trying to keep up, and keep his head above water as he all but drowned in pleasure, he didn't know it was coming until it crashed over him. At first he thought a wave had descended on them, despite the lack of a water source. A half gasp half wail left his lips, eyes wide, body trembling like a leaf. Holy grace and haloes what...this was it, wasn't it? An orgasm?

He got his answer as Dean snarled above him, teeth latching onto his neck as a knot swelled inside him. Castiel didn't even have the breath left for a cry as teeth broke skin. Instead he lay there, the feathers on his wings quivering, feeling wave after wave of sheer ecstasy-laden pleasure roll though every inch of his body. This compounded when the knot expanded fully, and he felt cum start to spill inside him. It was oddly warm, pleasant, not at all like he'd worried about.

Slowly, gradually, the pleasure started to draw away. Castiel felt oddly tired, but pleasantly so. A little drowsy, but oh so good. His eyes fluttered as Dean detached from his neck, giving the wound a light lick before settling himself over the Omega. The weight and warmth added to the drowsiness, but Castiel forced his eyes open. What if it was insulting, falling asleep right after?

The spark of worry was quickly snuffed as a hand started to stroke the feathers of one wing, still splayed on the hillside beneath him. The Omega shivered a little, unused to anyone besides himself preening the dark feathers. Just like everything else Dean had done to him so far, it felt good.

Warm lips pressed to his ear, and the Alpha murmured, "Get some rest if you need it, Cass. I'm guessing we've got half an hour before my knot dies down. I'll wake you up when it does."

Castiel hesitated, but then forced himself to relax. It wasn't actually that difficult, just giving himself over to his Alpha's wishes and what he already wanted to do. He let his eyes close all the way, his body relaxing fully beneath his mate's. As he started to drift, still on cloud nine, he felt soft lips press to his temple. Mmm, yes Dean Winchester was well worth the wait.

BREAK/BREAK\BREAK

It had been Gabriel's intention to provoke the Alpha. Phrases like 'Alpha enough' usually did the trick, more often than not getting a blind charge when he taunted them during the Chase. That said, he hadn't anticipated this sort of reaction.

There was a fraction of a second before the Alpha, Sam, did something. In that second, his eyes flashed, lips twitching upwards slightly. Then Gabriel found himself jammed bodily up against the nearest tree, his feet well above the ground, and his mouth under attack. Sam was through his lips, passed his teeth, and exploring forcefully before the Omega had time to react. It took his breath away, both literally and figuratively. Arms were locked around his waist, keeping him up so the rough bark wasn't the only thing left to the job. He hooked his legs around the Alpha's waist, grabbing broad shoulders before trying to fend off the invader.

A deep, rumbling growl sent a shiver down his spine, his wings ruffling a little. His oversized teddy bear had gone dominate Alpha in a heartbeat. Holy grace it was a turn on. The Omega had already felt his instincts starting to spike, despite the lack of an actual chase, but now they were swelling just as fast as his cock. He felt the familiar tingle as slick started to manifest at his hole, but didn't have the usual annoyance that accompanied it when he wasn't trying to get himself off.

Whether it was having an Alpha he actually wanted for a change, or the kink of getting mated in a forest with someone he'd known for all of two minutes, Gabriel felt the sudden urge to give himself over to the Omega instincts starting to well up. The moment he did, another growl came from the Alpha. One hand unwound from around him to start tugging at his clothes. Unlike Sam, he usually kept to Angel garb when he wasn't down on earth. This meant a few quick strategic tugs was all it took to send the white cotton to the forest floor.

Whining in his throat, the Omega wiggled a hand between them, tugging at Sam's belt. This was taking too long. Yes, great, he no longer had clothes to get in the way, but this Alpha was still fully dressed!

Said Alpha had moved to his neck, letting him pant in air, one hand running up one now bare leg, hooking under the knee. Just when Gabriel thought he might have to dump this Alpha onto his own back and undress him himself, Sam pulled them both away from the tree. He hurriedly put both arms around his neck, wings fluttering a little to keep his balance. Sam actually chuckled at this, and the Omega glared at him.

"What are you-

If he wasn't such a good kisser Gabriel might still have punched him. He drew an arm back anyway, but before he could let the blow fly his back came into contact with long, soft grass. Much nicer than the rough bark. He considered this, then relaxed. Instead of attacking this oversized, oddly adorable Alpha, he helped the hurried process of getting the human clothes off. Sam was fumbling a little, so Gabriel pitched in, tugging his belt open and undoing the jeans before making quick work of the boot's laces. Seriously, had he thought this through? Or had he just not thought he'd catch an Omega?

After what felt like far too long, Sam dropped down over him once more, one hand tangling in his hair as the Alpha kissed him once more. It was slower now, more thorough. Gabriel actually felt his toes curl. That never happened. Contrary to his father's wishes, he wasn't a blushing virgin. Admittedly most of his escapades had been with humans, but they were supposed to be experts in this field.

He was about to tell Sam to get on with it already, toe-curling kiss or no, when he felt the Alpha's free hand trace down his side. The touch was feather light, fingers tracing down every rib, skimming down his waist to his hip. He wasn't what one might call 'ripped', at least not visibly thanks to his love of sweets, but he was hardly fat either. He'd heard of some Alpha's who liked to fatten up their mates, others who wanted a carved David complete with the toned muscle. Which one did-

How his mind had even started to wonder, Gabriel had no idea. What little space was left for such things vanished the moment callused fingers brushed his hole, already gushing slick. His hips bucked into the touch, an embarrassingly needy whine escaping his throat. Sam only hitched his thighs wider, scooting a little closer as the Omega hooked his legs around the small of his back. His hands were drawn upward, tracing broad shoulders, muscled arms, a toned chest...holy grace he might not be a David but Sam certainly was. If he wasn't desperate to get mated he'd want to step back and admire the sight.

But he was, so he didn't. Instead he tugged Sam as close as he could, trying to impale himself on the fingers still teasing his hole. "Damn it, stop teasing!" The Omega had meant for it to come out as a growl. It sounded more like a needy whine. Still, it worked.

Sam's hand vanished. No sooner had Gabriel noticed this than he felt something press inside him. A gasping cry left his lips as Sam slid in experimentally. Somehow even now, pupils blown out so they were solid black, swamped with the same drive he was, this idiot Alpha was trying not to hurt him. Despite Gabriel's best efforts, he continued to do so, at least until he was buried up to the hilt. Satisfied he wouldn't push the Omega beyond his limit, whatever might have been holding Sam in check until then vanished.

A second cry in as many minutes was torn from the Omega's lips, but he didn't care. The hand not braced on the ground was wrapped around his cock, twisting and tugging expertly, using his own slick as lube. A hot mouth took it's sweet time, descending on one nipple to suck and lick before moving to the other. All while that delightfully proportional cock drove inside him, again and again, never the same depth or angle twice, occasionally with a rolling thrust, and never once missing his prostate. Gabriel had fully intended to reciprocate, really, but it was all he could do to hold on for the ride. When he did try to buck into the thrusts, or reach up with an unsteady hand, Sam pushed it back down. Once he'd even had the gall to lean up and growl in his ear, "Don't make me flip you over. I like seeing your face." He'd then given the shell of his ear a light nip before returning to his work.

Holy grace and haloes where the hell had Sam Winchester been all these centuries?

In the end, he'd climaxed embarrassingly quickly, but he hadn't been the only one. Sam's pace was going erratic, his thrusts getting rougher even as Gabriel's back began to arch on the soft grass, feeling his face start to contort. They came within seconds of each other, the Alpha with a deep throated snarl, the Omega with a whimpering wail.

Gabriel's vision actually went white. The orgasm alone was way more than he'd ever experienced before. Colors and images were starting to return when he noticed why this one was also longer, and probably more intense. Sam's knot was starting to swell inside him, locking them in place. A side effect of the knot was that almost twice the amount of cum was ejected, hence the prolonged experience. Gabriel had never been overly fond of that feeling before, an added reason to insist on condoms during his earthly romps. This, on the other hand, felt good. Amazing. Filling. A warm sensation swelled in his belly as the Alpha's cum continued to fill him, held in by the knot.

The Omega was still reveling in this when he felt teeth clamp down on his neck, breaking skin. At first he went ridged, but then slowly relaxed. Gabriel closed his eyes, reaching one hand up to stroke Sam's hair. And to think he'd toyed with the idea of refusing to let whatever Alpha that might catch him give him the mate mark. They already stared enough, an archangel Omega. Give them something else to stare at. An archangel Omega with a mate.

Sam pulled away carefully, licking at the wound a little. Gabriel opened his eyes lazily when he shifted, apparently unsure of what to do with himself. He reached up with his other hand, using both to hook over those muscled shoulders.

"Lay down," he urged, tugging the Alpha downward.

Eyes gradually returning to that puppy brown snapped up to his face. "But-

"No buts, just do it. Even if we weren't hardwired to like it, your weight's dispersed. Besides, I'm getting cold, or I will now that we've stopped moving."

That seemed to do the trick. Sam carefully settled on top of the Omega, wings still half spread behind him in the defensive, dominating pose. Gabriel's own were spread out to either side, fully extended and limp on the ground. Sam wasn't exactly an oversized pillow, but it was a comfortable weight, and he was radiating a delightful warmth.

Gabriel closed his eyes, extremely content. If he were a cat, he would have started purring. Just wait until be brought Sam home. That was the next step in the tradition, if memory served. The Omega would bring the Alpha to see their family, and then vice versa. He hadn't interacted much with the Winchester clan, though he'd heard a lot, and he was curious. To be a part of a clan that would encourage rather than sneer at his fascination with humans was a pleasant thought.

The Omega yawned, eyes fluttering closed as Sam nuzzled his neck. The flow of blood had stopped on the mate mark, and if he remembered right within a day it would be healed to a silvery scar. It could be anywhere from twenty to thirty minutes before the knot went down, and he was tired. He'd been flying around a lot today. Normally he'd nap after the picnic, but that wasn't the case this time. Maybe he could doze, just a little...
