As a high class alpha as well as a Fatui Harbinger, Tartaglia has never had a problem attracting the eyes of omegas. The problem was within him. Despite being an alpha himself, only the aggressive and dominating pheromones of other alphas attracted him. This wouldn’t be a problem, if Childe himself wasn’t a very aggressive, well built man himself. The moment he tried to actually fuck someone, their alpha instincts would combat each other. They were lucky if it ended in just a fist fight, the Harbinger having paid out lots of medical bills for leaving some of his attempted hookups nearly on their deathbeds. So the Harbinger stayed a virgin and found a way to quell his sexual desires through battle. He stopped thinking about finding a mate or ever sleeping with anyone, up to the point he was stationed in Liyue.
The moment he met Mr. Zhongli, he was enamoured. The older alpha was elegant and unfazed by the world, sometimes to an alarming amount. Childe found himself spending less time going out to train in the wild and more time tracking down the funeral consultant to fill up his days with the enchanting man. To the point where his rut was triggered again for the first time in years. That week was very hard for the already feral Harbinger. He spent it holed up in his apartment granted to him by the Fatui, courtesy of the Northland Bank. The first day right after it ended, he went looking for Zhongli.
The man smiled as he approached, looking absolutely beautiful and so tasty. Wait, tasty? In the middle of the street, Childe collapsed. He felt the heat of his rut pour into him, narrowing his vision. He vaguely noted quite a few people passed out from the strength of his pheromones, while others looked stuck in place in fear. Everyone including the other alphas in the crowd. Everyone, he noted, except for the mysterious Mr. Zhongli who was covering his face in shock. Childe locked onto his gaze, feeling a growl that cut off into a whine pull out of his throat. Childe felt a shiver run up his back as Zhongli approached him. Such a strong alpha to resist his dominating pheremores, except when the man released his own, Childe fell into a coughing fit instantly. They were so strong, demanding Childe to submit and give himself over to the stronger alpha. His reason was lost as he was scooped up into the consultant’s arms. He vaguely heard Zhongli apologizing to the crowd for the disturbance his mate made. His mate? Child? Zhongli’s? His head swam and it hurt to ponder on it, so he decided to just happily accept these circumstances and take advantage of Zhongli’s help. As he was carried back towards his room, Childe nibbled and bit Zhongli’s neck and shoulders, dissatisfied as his teeth ground into thick fabric instead of the soft give of skin.
“Not fair, you wear too many layers.” He whined, frowning. “Zhongli, does this mean we’re dating now?”
“Did you want to? You’ve told me a bit previously about your past dating attempts. Do you think you’ll be okay trying with me?”
“Something tells me-” Childe took a deep breath, feeling his mind go hazy from the lust. “-that it’ll be alright with you.”
“Is that so?” Zhongli hummed, smiling as he rubbed Childe’s neck right over his scent gland. It was making Childe’s pheromones pour out, spreading the scent of how badly he wanted Zhongli to mate him, hidden in the essence of the air right before a storm hit. That tension that built before the first crack of thunder in the sky. That was Childe, to Zhongli. “What if I’m a little rough? You seem the type to fight back.”
“Want it, Mr Zhongli. I want you.”
“Alright, sorry if I get swept away.” With that, they made their way back, Zhongli already preparing in his mind.

Childe felt the fever of his rut subsiding enough to focus his vision again. Suddenly he realized how sensitive his body was. He looked down in shock to see himself tied up to the bed frame from each limb, fully naked and spread open. In fact, his ass was spread wide open for Mr. Zhongli who was sucking on the twitching, muscular ring of his ass. His tongue had to have been working him open for a while, as he felt loose and empty when he sat up. “Are you coherent again, Childe?”
“Mr. Zhongli... what?”
“I was waiting for you to wake up and consent first, but I have been drawn to you since our first meeting so long ago. You called out to me and started your rut. Is it too narcissistic of me to hope you hold the same want and affection I hold towards you?”
Childe felt his heart skip a beat. “No, Mr. Zhongli! I-I want you-” He cut himself off, horrified. “Actually no, not you Mr. Zhongli. Anyone but you.”
Zhongli kept his smile the same, but his eyes narrowed as his pheromones gave away his anger. “Anyone but me? Why is that?”
“I get violent. I don’t want to hurt you.” Childe sniffled, feeling sensitive from the cool air. He wouldn’t be able to live with himself if he hurt the intelligent man before him.
“Then as long as I restrain and dominate you fully it’s okay?” Zhongli had a serene look to his face, but Childe felt warning bells go off in his head.
Still, he really wanted to give Zhongli his first time and finally feel the satisfaction of his rut releasing. “Okay; if you’re okay with me, I will give my everything to you.”
“Yes you will.”
___________
Their pheromones swirled together in the air, mixing. It was everything Childe wanted, yet still made is blood boil from his alpha side. Zhongli had made sure he was comfortable but unable to move for the past hour. He had only used foreplay but it had been enough to set Childe off. Zhongli didn’t give up or get reckless back, like Childe’s previous men. Instead, he asked Childe if he could try to use a different method to have the Harbinger submit. That’s when he brought out the knife.
Now small cuts littered his torso and neck, amidst deep bite marks that bled down his chest. He growled and snarled every time Zhongli cut into his chest or bicep, toying with him. Watching the way the Harbinger slowly began to shiver and moan from the pain. Was he being dominated through physical pain? It was true that the Harbinger used fighting to bring down the effects of his rut until bloodlust replaced his normal rut cycle. Did Zhongli figure out the connection from their talks?
Surely, as Zhongli dug the knife’s tip into Childe’s shoulder and twisted, a high pitched whine broke out from behind his previous snarling. Zhongli always made sure to suck and bite each knife mark, adding to the pain by easing the cuts open wider with his tongue. Childe decided he liked the feel of his skin giving in to the soft, warm tongue probing and stretching him.
That’s how it started. As Zhongli worked open his cuts, he also began to open up Childe’s ass with his slippery fingers. Childe’s own blood and precum making his hole sticky. His cock twitched. He felt Zhongli’s cock, still in his pants, grind against the messy hole, causing him to snap at Zhongli’s neck. His teeth clicked together painfully, but Zhongli just bent his finger and cooed as Childe’s dick swelled from the stimulation. “I wonder if I can make your cute dick knot the air. Should I suck on it and let you impregnate my mouth before I take your pretty little ass and rip it apart as I swell and fill you up?”
“Fill- just fill me right now. Wanna- I wanna cum hmmm ah- Just like that- I wanna cum from your cock. Please, Mr. Zhongli.” Childe whined, feeling too loosened up already as it was. Sure he was still a bit aggressive but Zhongli had him tied up tight. They should be fine, so why was the funeral consultant waiting? “I want you so bad.”
“So both of your mouths say, gaping open and beggin for me to shove it inside, but you’re not quite there yet Childe.” A drawn out, frustrated growl rumbled from his chest and Zhongli patted him to calm him down. “Patience, my love. I’ll peirce you soon, but I want you to fully submit first. You’re so close.”
“I’m so close.” Childe echoed, whimpering.
“I know, baby. Just a bit more. Can you expose yourself for me?”
Childe was already very exposed, his asshole fully on display and clenching around four fingers. Four? How big was Zhongli? He still hadn’t taken off any of his clothes, despite Childe being completely naked. Still, he knew exactly what Zhongli meant. It was hard. Childe felt his vision go red as he tried to bare his neck to the alpha over him. Just as he started to snarl again, Zhongli cut into his thigh rather deeply while biting down hard into his shoulder. Childe thrashed, animalistic noises gurgling from his bleeding mouth where he had bit into his cheek to try focusing. It wasn’t working. The pain was clouding his mind, making it easier to slip into his alpha instincts.
Who was trying to mate and impregnate him, an alpha? A dominant alpha at that. Childe tried to kick out and just managed to get rope burns on his ankles. Zhongli let go, only to bite down again, harder. Warm, thick blood was covering his goosebump riddled skin. Every bite leading towards his scent glad made his body feel hot and cold, fighting within him just as much as outside. He wanted to give in. He wanted to rip this alpha to shreds. He wanted to make love to Zhongli. He wanted to flip them over and breed that other alpha until his seed made his stomach practically burst. Childe wanted Zhongli. At the end of the day, he didn’t care how. Both sides of him just wanted the man before him. Strong, resilient, smart. “Zhongli, Zhongli now. Do it now, please. I promise. Do it please.”
“Almost, my alpha baby. Just trust me.” Childe nodded, flinching as Zhongli slices his cheek lightly with the knife. His tongue dragged slowly over the skin. This would have been dangerous earlier, but Childe felt himself push into the intimate action. He felt his body starting to relax. His rut was rearing up again, fogging his mind. But instead of the burning ache, Childe felt a soft, fuzzy satisfaction in the alpha’s hold. One last bite had Childe screaming and seeing stars, Zhongli’s teeth digging into Childe’s scent gland and pumping his own pheromones into him. Childe felt his brain go numb, tingling. He wanted Zhongli to pump him full of semen until it spilled from his mouth. His body spread open further for the alpha, finally truly accepting submission towards the ancient alpha. It took a lot longer than Zhongli thought it would, commending within his own head, Childe’s resilience and picky tastes in a mate. That worked out for the archon though, because it meant no one else had touched his mate before and he would get to be the first to scent him deep within his guts. When they were done, Zhongli wanted even Childe’s sweat to smell overwhelmingly of Zhongli, attesting to how well and deeply fucked his mate had been.
With a single thrust, Zhongli bottomed out into the blissed out alpha. With a goofy, already fucked out expression, despite the real fucking yet to happen, Childe pressed into his stomach. “No one has ever gotten into here before, Mr. Zhongli. Are you gonna make me yours forever now?” He brought the alpha closer in a tight hug, nibbling on his neck as Zhongli growled, aroused. “I can’t wait for you to fill me with your seed like a little omega. Will you fill me up with your pups now that you’ve gotten your dick in me, Mr. Zhongli?”
“Watch your mouth right now, Childe, or I’ll fuck you until your body forms a pretty little cunt to really impregnate you with.” Zhongli wanted to bitch him into an omega?
Childe’s grin was so happy, thinking about submitting to the man inside of him, down to his very dna. “One day, I hope you’ll be able to take both of my holes’ virginities then. I’ll be looking forward to it, Mr. Zhongli. It’s a promise.” With that, Childe let out his pheromones again, making Zhongli’s cock swell from the scent before he truly started to fuck Childe. Zhongli was already thinking of how and when he would bitch this pretty alpha beneath him, until he could swell him full of his seed and children for the rest of their lives.
