Chapter Text
Crepus hadn't known taking in a scared, soaked orphan one rainy night would be such a lucrative decision, but he's damn glad he did. The sheer number of bribes he's been plied with since Kaeya became of age - some even before that - has become large enough to rival the income from his winery business. Suitors from distant lands have traveled far for a single glimpse at the omega's famed beauty and, upon seeing it, immediately ordered their servants to open their coffers.
The problem is actually picking a suitor. Treating it like an auction would be ideal, of course, but Crepus would rather not be seen as a barbarian trading away his adopted son's hand in marriage for mere money. Besides, Diluc has started to look at him suspiciously recently and even gone as far as to make various cryptic remarks about "being careful what you do about Kaeya," so Crepus decides to stick to tradition and hold a breeding banquet.
He sends invitations to every single suitor who's ever given him money (only those who pay a minimum entry fee will actually be admitted, of course. There are simply too many people, and Crepus is worried about Kaeya's durability, you see), orders his servants to prepare the most exquisite banquet in all of Teyvat, and then, when the day arrives, personally straps Kaeya to the breeding bench.
The manor's ballroom, scrubbed sparkling clean from top to bottom and decorated with luxuries worth fortunes, holds a veritable mass of eager alphas. Crepus says a few introductory words, making sure to acknowledge the highest donors of the night - he has hinted that more bribes may increase their chances, but biology is biology, and a hint is not a promise - while Diluc stands next to him with his arms crossed and glowers at everyone.
When Crepus lifts his glass, the crowd cheers and disperses. Some wander to the buffet table, deciding to wait for later for their chance, some simply gather around Kaeya to watch for a bit, and the rest - the bold ones, the richest ones - file in line.
Diluc is the one guarding Kaeya, making sure each alpha only has one turn in the interest of fairness. It's a bit unusual - usually a servant or some such takes this role - but he had insisted on it with such a stormy expression that Crepus had relented immediately. Diluc glares at the first alpha in line with the same look.
"Name," he demands.
The alpha grins, completely fearless. "Childe."
Diluc grits his teeth and shifts his glare to his father. Crepus shrugs. A rich man is a rich man, Fatui Harbinger or not.
Diluc scowls and gestures to Kaeya, who's now squirming in his restraints. "Get it over with, then."
Childe clicks his tongue. "No sense of romance, this one." He steps towards Kaeya and runs a hand along his side, prompting a shiver. "Hello, gorgeous," he says lowly, looking like he's speaking more to Kaeya's soft pink cunt than to him. He trails two fingers over the opening, delighted at how wet and welcoming it feels. Slowly pushing his fingers inside, Childe soaks up Kaeya's helpless gasps and feels his mouth water. How he would love to bury his face in these folds, thoroughly debauch Kaeya with his mouth and tongue, hear his cries and moans as he gives him pleasure he has never felt before. Unfortunately, he can already see the other Ragnvindr kid starting to get antsy from the corner of his eye, so he speeds things up.
He pulls his fingers out, licks them just for the taste - and what flavor it has, sweet and succulent - and then undoes his pants. The alphas around them are crowding closer now, the stench of jealousy and arousal equally strong, some already palming themselves through their clothes. Childe pulls his heavy cock out and rubs it slowly against Kaeya's folds. Leaning over, he murmurs in Kaeya's ear, "Ask for it nicely, sweetheart," but Kaeya remains stubbornly silent. Even so, Childe can hear his breath coming faster.
He laughs. "So hungry for cock, aren't you, little omega? Just ask for it, and I'll give it to you." He takes himself in hand and teases the tip at Kaeya's entrance, feels him subconsciously wiggle back like he can tempt him to sink into him. Childe has resisted many enticing omegas before - as a Harbinger it's not like he's unused to having his pick of mates - but the way Kaeya squeezes his eyes shut, lifts onto his toes and pushes his bottom out more, then says "please" is so excessively obscene that Childe has to gather himself for a moment before he smiles, says "good girl," and plunges in.
Kaeya wails, gripping at the legs of the bench with bound hands. He's undoubtedly overwhelmed - Childe is not small by any measure, and tradition dictates that omegas participating in breeding banquets must be virgins. Childe bathes in the satisfaction of being the one to take the virginity of Teyvat's most desired omega - certainly no easy feat. Even before the banquet was announced Childe had already made the necessary bribes and threats, and now he reaps the rewards. Kaeya's cunt is exquisite - wet, warm, tight as sin. Childe has to keep from embarrassing himself with a wanton moan, instead smoothing a hand over Kaeya's back to collect himself and then pushing the rest of the way in.
"Fuck," someone in the audience hisses as Kaeya cries out again, and another lets out an involuntary growl.
Crepus, looking suspiciously pleased, suddenly clears his throat and says, "His mouth is available for use as well, of course. As many times as you wish." Then he dawdles off to go mingle with the various dignitaries at the buffet table.
Everyone watching Childe smugly taking his pleasure looks sorely tempted at the offer, but in the end no one moves. Archons know how many nights these alphas have restrained themselves, saving their seed for this one chance to breed Kaeya. To now spend it all in his mouth, as immensely attractive as the idea is, would be a waste of all that effort.
Still, it's certainly a test in restraint watching Kaeya whimper, letting out choked little cries of pleasure that make them groan and palm themselves harder. Childe is letting out grunts of exertion now as he drives himself deep in Kaeya's tight cunt, the force of his thrusts shoving the omega back and forth, pulling quiet "uh, uh"s from his mouth. Kaeya keeps his eyes tightly shut, likely trying not to look at the crowd of alphas watching him hungrily, but the noises dragged out of him betray his bliss.
"What a slutty thing," Childe manages to say, breathing hard. "Good for nothing but being bred, hm?" He continues hammering into him, each thrust rattling the restraints around Kaeya's limbs, squeezing the flesh of his ass in his hands. Every time he pulls out, Kaeya's walls cling tightly to him, unwilling to let him go.
"Fuck, look at him," he hears someone from the crowd groan. "Taking cock like he was made for it."
It truly has been some time since Childe has had an omega take him so well - the pleasure is intense, overwhelming, and much too quickly he feels himself tipping over the edge. When he plunges his cock into Kaeya one last time and comes, gasping in an entirely undignified way, his vision whites out. Kaeya cries out at the hot cum flooding his womb.
His first load, Childe thinks to himself, pleased, when he catches his breath again. He tugs his hips lightly to feel the knot catch, prompting a whine, and reaches into the gap in the breeding bench to rub at Kaeya's stomach. "You think you've taken?" he coos at him. "You're so full, you sweet thing." Kaeya trembles in his arms, still gasping, and the tremors work through his body and squeeze lovingly around Childe's cock. Childe groans wholeheartedly and feels more cum release into Kaeya's body. What a good omega, milking him for seed.
"Made for this," he repeats.
When Childe's knot finally goes down, he steps back and watches hungrily as a river of cum flows down smooth thighs. He shoves two fingers back in Kaeya, pumps them in and out and watches more drip out of the ruined, puffy lips.
"Hey," the moody Ragnvindr heir snaps at him. "Your turn is over. Get out."
"Just admiring my work," Childe says, amused. He wonders whether the kid is simply overprotective over his adopted brother or whether there's a more complicated reason for his overtly possessive behavior. Either way, there's no going against tradition; even if he does want Kaeya, he has as much of a chance to own him as Childe does.
"Thanks for the fuck," Childe says to him, because he is still nothing if not a smug bastard, and then before the kid can lunge at him, he pats Kaeya's ass twice and escapes into the crowd.
Diluc nearly flies after him but, at Kaeya's whine, he grits his teeth and begrudgingly looks to the next alpha in line. "Next," he snarls.
