Kaeya Alberich was rarely a man without some ulterior scheme behind his actions--and even more rarely, a man without a plan.

He knew full well what he was doing when he walked into the Angel's Share that night, reeking of the last few hours of pre-heat before it would take him.

He had waited for two days, watching carefully from a distance, for Diluc to go pick up one of his shifts at the start of the afternoon.

No suppressants. No heat masks. Kaeya enters the tavern smelling like sweet lilies and mint candy, saccharine and intoxicating.

There are too many eyes on him in a split second to count--but all that matters are one set of them, burning and red and intense.

Exactly the ones he wanted on him, scraping from how he'd worn his collar particularly open, and forgone the fur at it, this time.

An offering, in gesture alone, intentionally provocative to one person in particular. No collar. No marks.

It screams the words 'I have been saving myself for you. You have but to take me.'

He orders one drink, and sips at it, and pours as much scent into the bar as possible.

Betas are gripping the arms of their unmated Alpha friends. The few Omegas that dare linger in the bar as well are trying to shed their own, but there is little that can be done in the face of Kaeya shedding all pretenses of pretending to be coy, for once in his life.

His tongue flicks out under the intensity of Diluc's gaze, collecting the last drop of wine from his glass, before he sets it down and makes eye contact, finally. In a soft, breathless little whisper.

"I think that's all, for tonight. I'm not feeling too well."

He is perfectly capable of handling himself, but he holds the smallest lilt of a pathetic intonation, a soft sound of despair.

It's enough to make half of the Alphas of the bar ready to jump at the bit to escort him home, to treat him well, to make it /better./

Diluc's restraint is threadbare, and when at least three Alphas stand to follow Kaeya the minute the steps from the bar's doorway out into the street outside, he turns to snarl in their direction.

He is unmatched in every possible way. They know this. They relent.

No one will risk that Pyro Vision--and no one questions it, either, when Diluc waits all of sixty seconds before he throws his bar apron down, leaves Charles charge of the bar, and chases after him.

Kaeya has made it as far as the fountain in the town square, and for once, it is empty.

Maybe he was regretting going out so close on the edge of his heat; his legs are weak, and even the air he breathes feels too warm. His head is spinning.

Before he can think about any of this, though, he hears the Command from behind him, full Alpha-voice despite the fact no one would /dare/ use that tone with him normally.

Except Diluc. Especially now.

"On your knees, Captain Kaeya. Bend forward."

Kaeya can tell when Diluc's voice is strained--his restraint is callously close to snapping, he knows him too well to let Diluc suggest anything otherwise. But his knees go out from beneath him immediately, the sweet keen of his Omega instincts eager to obey that Command.

"Diluc-" he gasps, not turning as he tilts forward.

Gloved fingers wrap through his hair, and push him forward until he has to catch himself on the edge of the fountain. He can see his reflection alongside the moonlight.

"I /said/ bend forward, Omega."

His face is burning, but that Voice carries through again, and he ducks his head down, wriggling his hips a little because that tone is accompanied by the scent of cinnamon and spice and raw Alpha. The hand not wrapped in his hair keeping his head down finds the hem of his pants.

The fabric almost tears with how quickly Diluc gets his pants down in the middle of the fountain square, dragging them only down to his thighs.

Kaeya's hair dips down to float on the water's surface.

The same fingers that had torn down his pants dip against his slit, and Kaeya can feel how leather glides along his skin. He's so wet, and yet Diluc still refused to take off his gloves.

Three fingers slide in simultaneously, too much, but he still wants more.

"Quiet," Diluc growls in Command once more, when Kaeya's lips part into a muffled cry. A morbid parody of the wishes normally whispered to the faith of the fountain.

It's a Command he has to try and follow, and he bites so hard against his lower lip that he nearly sobs while Diluc fingers him slowly enough to be maddening--slowly enough to make him drip rivers of slick down his thighs, until Kaeya's trying to ride his gloved fingers still.

"Did you come in just for this?" Diluc snarled, lean over his shoulder, grinding his fingers deep within him. "Hoping some Alpha would use you like this? You should know better than to go into public in heat. You brought this on yourself."

"Please," Kaeya whispered, squeezing those fingers tight as if on command. "Not 'some Alpha.' You. You, I want you-" He rasped, toes almost curling as he lifted his ass into those ravaging fingers. "Diluc, come back to my nest, come spend my heat with me."

Diluc's breath hitched at the invitation--something precious from an Omega, but he's far too lose into his temporary aggression to be sweet for right now.

He'll take Kaeya back, after he's made it obvious just who he belonged to.

Kaeya had come out to tease him into this, after all, he'd give him exactly what he was asking for.

The Omega under him went tense at the sound of Diluc's belt coming undone and his pants falling low. "Diluc, not here, we're-"

He can feel the warm, thick tip of Diluc's cock already nudging at the soft, plush give of his hole, soaked and stretched and begging for an Alpha more than his lips could manage.

There, in the middle of the town square with Kaeya bent over the fountain's edge, Diluc sinks in.

His fingers dig into the edge of the fountain, and his startled little cry died on his lips before he can get it out fully--because Diluc's fingers twist his hair around them, and pull back to startle him out of the sound.

"Take it quietly," Diluc hisses. "Like a good Omega."

Tears well in the corner of Kaeya's eyes, though they're far from pain or misery--embarrassment, maybe, but the distinct sensation of being stretched just how his body wanted played a good part in it, too.

He'd wanted this. He'd wanted Diluc. He /wants/ Diluc.

"Look at how wet you are," Diluc murmurs, sinking into him easily on the first push, setting his teeth at the back of his neck. "You hit your heat the minute you got here, didn't you? Ready to be filled. What if I hadn't been the one who'd followed you?"

Diluc rolls his hips firm against the give of Kaeya's ass, grinding in him. Kaeya could swear he feels his tip already nudge against his cervix, tapping it. Butterfly kisses.

Promises.

"Some other Alpha would have knocked you up tonight."

Kaeya whines.

"It's got to be you," Kaeya insists, spreading his thighs a little wider, encouraging Diluc deeper. He wants to feel him ram his cervix. He wants to feel every drop of Alpha seed flood his womb. "I want you you breed me, Diluc. Please, please-"

"I intend to, Kaeya."

It's whispered against his ear, a threat, but Kaeya's instincts sing with delight at it, grinding back against him.

The time for words is over, though, and Diluc pulls Kaeya up by the hair against to sink his teeth into the back of his neck. A claim mark.

He slams into him with abandon, his fingers leaving Kaeya's hair to shove into Kaeya's parted lips instead, keeping him quiet while he rails Kaeya with no rhyme or rhythm.

It's hard to keep either when his knots is already half-swollen--and he fucks Kaeya with that, too.

Kaeya can feel it pop in and out of him every time, not large enough to take just yet, but large enough to drag along his inner wall, then tug Kaeya back hard whenever Diluc pulls it out.

Diluc's fingers are the only thing that keeps him from screaming into the night air.

He's finished twice by the time Diluc's knot actually takes--but feeling his tip press flush to his cervix again before he spills into him is enough to make him whimper and grind against Diluc further, even with the knot rapidly swelling in him.

Not a drop escapes.

"Beautiful," Diluc whispered, pulling back to watch the slight pull of his knot still stuck in Kaeya as he moved. It made Kaeya shake almost mindlessly under him--but there was the sound of an approach, too. Diluc shifted quickly enough to pull their pants up--barely hiding it.

Kaeya was distinctly aware of the sensation of both of them shifting--then, with Diluc's cum and cock stirring in him both, he's pulled into the Alpha's lap as someone from the bar passes them.

Diluc manages to make it look like Kaeya's only sitting in his lap, drunk.

And Kaeya is, really--drunk on pleasure, drunk on the feeling of being bred, drunk on the scent and feeling of finally being /claimed/, and his Alpha's aroma filling him just as his seed had.

Diluc glares at them until they move on their way, before he tilts Kaeya's chin.

He kisses him, slowly, steadily--something Kaeya had been afraid he wouldn't want to do. He had forced Diluc's hand, after all--he had intentionally played into everything the Alpha would not be able to refuse.

If everything went well, he'd be carrying his bastard, too.

And yet here Diluc was, sweet after the storm, nosing against his temple, before his hand reached down to squeeze Kaeya's thigh.

"Don't think we're done," he offered only afterwards, tone dark. "I'm taking you to your nest, and breeding you through your heat, Omega."

Kaeya's breath hitched, and when he glanced up, Diluc's gaze was dark and possessive.

Perhaps he had not been as in charge of the situation as he had anticipated.

It seemed Diluc had been waiting for this for a long time.
