Step one of dominating Kaeya was to not wait for an opportunity to present itself.
Afterall, had Kaeya ever waited to get his way with him? Tartaglia knew the answer was ‘no’. The execution of Kaeya’s bold, sexual advances were swift, deadly, and all-consuming. After a red-herring of a present like roses or wine, Kaeya would man-handle Tartaglia the way he liked, usually ending with him spasming as he orgasmed inside of Kaeya, in Kaeya’s hand, or with Kaeya inside of him.
They were a very versatile couple where dynamics were concerned, Tartaglia knew.
So it did not make sense why Kaeya was the one initiating all their sexual escapades rather than him from time to time. Maybe Kaeya was an expert at reading his libido levels. He could read Tartaglia like an open book and coax him open with a well-oiled finger. No wonder Tartaglia was at the mercy of his strong initiative.
Now, however, the tables were about to turn. Tartaglia was on his way to dominate Kaeya. To make a mess of him, to utterly humiliate him when he lost control under Tartaglia’s whims.
Thus commenced step two of dominating Kaeya, which was to track him down as fast as possible.
Kaeya had many eyes and ears in Mondstadt, and not only because he was blessed by the Anemo Archon. He had such a comprehensive network of informants that he could conjure a solid picture of events from their intel alone. If the phenomenon of Tartaglia prowling the streets caught wind, he would become the hunted instead of Kaeya.
But Tartaglia was nothing if not stealthy. His days of being a Harbinger, calling the shots when undergoing covert missions, had allowed him to meld into the shadows whenever he travelled.
When Tartaglia burst into Kaeya’s office that afternoon, the look on his lover’s face was priceless.
“How did you get in?” Kaeya asked, bemused.
“Told your guards that you have business with me,” Tartaglia answered smugly.
“You couldn’t have told them you were my boy-toy? Perhaps they would have approved more - such a pretty ginger like you being put to good use. On my cock,” said Kaeya with perfect neutrality.
Tartaglia tried to ignore the twinge in his pants as he growled, “I made a copy of your seal, Captain. Look.”
Step three of dominating Kaeya was to always. Be. Prepared. Confronting someone as unrepentantly devious as Kaeya was just to warrant being wrapped around his little finger.
Tartaglia reached into his pants pocket and brought out an exact replica of Kaeya’s official seal. Kaeya seldom used it, for he had nothing to officiate without cavalry in the first place. He did, however, use it to place his signature on the occasional important document that did not require Jean’s overseeing.
Kaeya raised his eyebrows as he slid it smoothly across the table towards him.
“Impressive,” Kaeya said silkily, and Tartaglia knew Kaeya realised he had met his match this afternoon.
“Still, I cannot see your purpose for visiting me,” put Kaeya mildly. He stood up, setting his paperwork aside. Tartaglia grew enamoured with the way he stretched, arching his back as he drew his shoulders back slightly.
Step four of dominating Kaeya, Tartaglia noted with growing anticipation, was to remember step number one.
The harbinger stepped closer, putting on a seductive smile. “Then perhaps you are blind. Have my charms blinded you so quickly?”
Kaeya snorted in bafflement, but Tartaglia did not lose momentum. Though, inside, he was panicking slightly. The last time he had tried to out-dirty talk Kaeya, it had backfired on himself with Tartaglia yelling at Kaeya to place his dick inside of him already.
Dirty talk was not his forte. He was better with his actions. Unfortunately, wanting to dominate Kaeya meant he could not give into his sexual urges first.
Tartaglia breathed in. And out.
Kaeya was staring at him through his lashes. It was unusual enough that Kaeya wasn’t vying to take the lead. Perhaps he had no idea of the full extent of which Tartaglia planned to cause him to unravel today.
Smirking at Kaeya’s wordlessness, Tartaglia tilted Kaeya’s chin downwards with his forefinger and thumb.
“I wonder what I shall do with you today.”
“Oh,” said Kaeya, infuriatingly. “So you want sex?”
Tartaglia narrowed his eyes, avoiding the answer. That would just give him the upperhand.
“Why not give into it already?” coaxed Kaeya, exploring each syllable from his lips languorously. “Why not ask?”
“Because,” said Tartaglia lamely, but harshly, “I am going to dominate you.”
A high chuckle escaped Kaeya’s lips. “I see. How are you going to do it?”
Tartaglia blinked. He hadn’t expected Kaeya to just accept it without resisting. There was something pliant about Kaeya’s expression that made Tartaglia present himself more tenderly.
Pushing Kaeya against the wall of his office, he crossed one arm above his head, before ruthlessly sliding a leg between Kaeya’s. The man was so attractive; especially right now, with his docile attitude that made the harbinger want to ravish his body. Tartaglia stared down lewdly, kneading his thigh repetitively against his crotch. Kaeya’s tight-fitting pants already gave the appearance of a slight bulge.
And then he stared into Kaeya’s eye, where a barely perceptible flush was appearing below it.
“How do you like it?” Tartaglia asked, licking his lips.
“Very… very nice,” Kaeya’s voice hitched, though he smirked right back.
“You’re very willing to give me the lead today. Have I truly caught you by surprise?” Tartaglia asked.
Kaeya smiled, shutting his eye briefly as his cock twitched in its clothed confines. Tartaglia definitely felt it, and dug his thigh deeper and higher against the responsive flesh, causing Kaeya to let out a soft, stuttered moan.
There and then, there was a knock on the door.
Tartaglia nearly jumped out of his skin as he backed away silently from Kaeya. Snezhnaya had no diplomatic meetings with Mondstadt. A Mondstadt soldier would much less tolerate them being lovers.
Kaeya, too, strode fluidly back to his desk. He pointed at the large cupboard, asking Tartaglia to hide inside.
But Tartaglia already had his plan rocking in motion; he wasn’t about to go about half-heartedly executing him. So he dove under Kaeya’s desk, slapping his long legs away. The chilly glare that Kaeya shot him excited him further.
“Come in,” Kaeya called politely to whoever it was at the door.
“It’s me, Kaeya,” came Jean’s voice.
“What a pleasant surprise. What can I do for you?” asked Kaeya with genuine friendliness.
“One of the guards reported to me about the appearance of the 11th Fatui Harbinger, Childe. He said this man, Childe, had business with you. Is this true? Have you seen him around?” asked Jean worriedly.
“Oh? I haven’t. The first and last time I ever heard of him was when he had made an infamous name for himself in Liyue," said Kaeya with a mixture of seriousness and casualness.
Tartaglia decided he had heard enough, and laid a cheek snugly against the outline of Kaeya’s cock. He felt Kaeya jolt imperceptibly.
Tartaglia grinned, and it was a truly evil sight. He moved his head up and down, adjusting the pressure applied by his cheek. When Kaeya took a while to respond, Tartaglia brought a finger up and scratched a line down the raised, coarse fabric.
The thighs around him quivered slightly. Tartaglia resumed his lazy scratches, making no effort to increase his pace or pressure. He heard Kaeya pant under his breath.
“Kaeya? Are you listening?” Tartaglia heard the snatches of conversation above him.
“Yes. Yes, I am,” said Kaeya quietly. He tried to stop himself from squirming as Tartaglia began to stroke him rapidly. He could barely concentrate on Jean's words as the man below him interspersed his rubbing with the occasional grab that hugged the outline of his very happy cock.
The bulge in his pants swelled. Tartaglia wondered if the arousal would show on Kaeya’s face through flushed cheeks and lidded eyes. He very much wanted to claim every inch of his body.
Wanting to make him lose control further, Tartaglia felt for his balls down lower, and cupped them roughly. After that, he drew three fingernails up the underside of his cock. He saw Kaeya’s abdomen give a shiver.
“I do think we need to increase our patrols around these regions concentrated with Treasure - ah,” Kaeya simultaneously cut himself off mid sentence. He was straining badly against his pants.
“What was that? Anyway, you’ve marked down those regions, right? Thank you, Kaeya, for making things so simple.”
“It’s a pleas-” Kaeya gave a moan that he managed to transform into a cough at the last second. Tartaglia had implanted the hot cavern of his mouth right on top of his crotch. He could feel Tartaglia’s teeth lightly grazing the tip through his pants, and felt himself go hazy for a while. He was going to murder and demolish Tartaglia after this.
“Do you have a cold?” asked Jean concernedly.
“No, it’s just - Well, it’s a slight cough. It’ll go away soon.”
“Alright. I’ve replenished the honey, so go make yourself honey water afterwards.”
“Of course,” said Kaeya straight-facedly as he lightly punched the top of Tartaglia’s head under the desk. Tartaglia gave his knuckles an affectionate nosing before resuming his biting.
Kaeya did not know how he could get hard with someone biting at his crotch. Alright, Tartaglia had the skill and intention to pleasure him. Still, the growing patch of saliva on his crotch was going to become cold against his skin soon. That would be uncomfortable.
“Are you sure you’re alright? You look bothered about something.”
“Yes, I’m fine, Jean. No, don’t come over - DON’T come over, Jean. I might have a contagious cough.” The panic in Kaeya’s chest abated when Jean sat back down, raising her eyebrows.
“I won’t bother you for much longer, then. I just miss your company,” Jean smiled.
“Aww, me too,” said Kaeya sincerely in return, before he nearly gulped as Tartaglia unzipped his pants without a sound.
Though Kaeya managed to keep a straight face and maintain an unbreakable composure, he couldn’t stop the feeling of hotness from flooding his veins. Tartaglia had released his cock into the air fully, and was taking it firmly in his hands. He jerked him off steadily, increasing his pace dizzyingly once that caused Kaeya’s eye to twitch.
Kaeya’s breath hitched again as Tartaglia dove his fingers under his balls, nestling them above his palm. He fondled them lovingly before sliding a finger to graze his hole barely. The weight of his upper body on Tartaglia’s hand meant that the friction against his balls was quite immense - that drove Kaeya quite insane.
He bucked his hips forwards as Tartaglia finally, finally took him in his mouth. He pressed his face into a hand which leaned on the table, because otherwise he might have moaned aloud.
Tartaglia’s wet mouth continued bobbing, up and down, up and down his girth. Kaeya gritted his teeth. He was about to come soon.
“Kaeya? Wow, you’re literally zoned out. You must be tired.” Jean rose from her seat, sending a jolt through Kaeya’s feverish mind.
“Go home early tonight. See you tomorrow.”
And with that, Jean mercifully left the room, Kaeya barely managing to say “goodbye” to her. It was just as well, because as Tartaglia sucked the tip of his cock with a loud slurp, Kaeya gave a delirious moan after those minutes of restraint, tilted his head back and felt cum explode down the back of Tartaglia's throat.
"Fucking… hell, Tartaglia," panted Kaeya, sounding beautifully debauched.
Tartaglia emerged from under the table, looking both impish and awfully smug.
"You taste delicious."
"Give me a taste, bastard," snarled Kaeya, curling a hand behind his neck to crush their lips together. They moaned against each other, Tartaglia relinquishing control for the moment as his own hips bucked his hardness against Kaeya unstoppably.
"Someone's needy," hummed Kaeya from low within his throat.
"No, no, you don't get to touch me today. I brought you exotic fruits to eat."
"I'm quite ready to murder you, ginger sweetheart," said Kaeya in a voice that rang with steel. "For trying to make me lose it like that. What are you hoping to achieve, hmm?”
“Oh, nothing. This could be the new normal,” quipped back Tartaglia.
Kaeya’s feral grin faltered. “What do you mean? You didn’t like all those times when I took the lead?”
“No!” said Tartaglia, reaching forth to cup his soft cheek tenderly, and Kaeya leaned into his touch, “I could never hate it. It’s just annoying when you get me to unravel, but you remain as perfect as a peacock feather.”
If there was something Tartaglia was good at, it was honesty. His honesty threw Kaeya off balance because of how Kaeya struggled with it himself. It was not that he preferred to lie; he had been conditioned by various traumatic events in his life that lying was the safer and better option for everyone. This was not something Kaeya liked to dwell upon, so he attuned himself back to the present moment.
“Oh,” was all he said.
“Yeah,” shrugged Tartaglia. “It bothers me. I want to see you mewing for me like a kitten when I prolong or deny your orgasm. I want to see you crying for me when I pamper you until you’re all hard and leaking. Get it?”
Kaeya smiled, tempted by his words. “I get it. What are you waiting for? Dominate me.”
The final step, apparently, when it came to dominating Kaeya, was to forget about the first four steps and just focus on being sincere. Kaeya was someone whom Tartaglia wanted to be sincere towards, since he was so outwardly friendly and charming. Someone who put on an exterior all the time had to secretly pine for sincerity.
Tartaglia wanted to give him all of that.
But first -
"I wasn't kidding when I said I brought exotic fruits," he drawled, and as Kaeya began to lower his pants slowly, Tartaglia helped him by wrenching them, in addition to his underwear, down his hips, giving his dick a playful squeeze.
"You sit down," and he pushed Kaeya to sit back on his desk, before proceeding to take off the remainder of his pants completely.
Kaeya spread his legs unabashedly, beckoning him closer. Tartaglia indulged him first, claiming his lips again deeply and possessively. He lavished Kaeya's mouth with his probing tongue and nibbling lips, and felt the flush caused by their combined raised temperature.
Then, he pushed Kaeya back with a hand on his chest, before drawing a packet out of one of his shirt compartments.
Before long, he dangled a pink, wide-bottomed fruit in front of Kaeya.
"From Inazuma. Called the Amakumo fruit. Take one and it's as fresh as dew. Take too many, however, and you turn purple."
Kaeya hummed, luxuriating against the table with evident desire in his eye. "I feel it's a metaphor for something."
"That's right, smart boy. You can't have too much of one thing, so I'll give it to you one at a time."
"Ohohoho. Does that mean I can't… touch myself?" And Kaeya proceeded to do so, his fingers wrapping firmly around his cock as he tugged at his own sensitive flesh a few times.
"Mhmm, you're testing me." Tartaglia encircled firm hands around Kaeya's wrists and slammed them behind him. Kaeya arched his back towards him, as if begging to be touched.
He shoved the fruit into Kaeya's mouth instead.
"Eat this."
Tartaglia unbuckled his own pants, sighing in relief as his throbbing cock stopped suffocating in its unbearable confines.
Kaeya chewed, making a face at how fibrous it was. Then his eyebrows shot up to his forehead as Tartaglia hoisted his hips up slightly and he began to tinker with his hole.
"Mmmphh!" was all Tartaglia heard before he slid a single finger gently into Kaeya.
He threw his head back, rocking against Tartaglia needily. Yet, Kaeya’s moans were muffled as juice slushed around his tongue and he did his best to grind the fibre down between his teeth.
Tartaglia thrusted his finger into him a few times, before speaking amiably, "I love it when you can't talk, comrade."
"Asshole," Kaeya managed to grunt out. Tartaglia snagged his finger against the ridges of Kaeya’s walls, feeling Kaeya go rigid and quiver against him.
“Now kiss me?” asked Tartaglia perfunctorily.
Kaeya shook his head, mouth still half full with fruit. Really, had Tartaglia gone so far just to incapacitate him?
“That wasn’t a question, beauty.” Tartaglia pressed his lips against Kaeya’s, forcing the latter’s mouth open and thrusting his tongue inside. Kaeya moaned helplessly against him, coughing but aroused by his actions. The harbinger tasted the lukewarmth of the half-chewed amakumo fruit, mixed with Kaeya’s rough, musky scent and saliva. He groaned roughly as he rubbed his length against Kaeya’s abdomen.
“Come, now, you must desire my touch,” said Kaeya breathlessly, wrapping his fingers around Tartaglia’s erect dick.
The harbinger slapped his hands away with a scowl, as much as he desired to hump into Kaeya’s hand until he witnessed stars. Kaeya gave an unexpected startled yelp which made the harbinger almost feel regret.
“You don’t get to do anything without my permission,” Tartaglia said, and kissed him softly on the forehead for good measure. He spat out fibre which had clung to his teeth earlier on Kaeya’s lap, and Kaeya looked grossed out.
The disparity between the harbinger’s consecutive actions was giving Kaeya whiplash. He did not know, between the throbs of pleasure in his lower half and his lover’s devious grin, whether to laugh or cry. He had a feeling Tartaglia wanted him to do both.
Kaeya shook with pleasure as Tartaglia found a good angle on his prostate and massaged it with every stroke.
"Go on, say it. Cry out how good I am at making you feel good," said Tartaglia seductively.
"Clean up what you spat out," hissed Kaeya, gesturing to his own lap.
Tartaglia withdrew his finger, causing Kaeya to curse and moan at once.
"You're good! You're fantastic at making me feel good. There - are you happy?" scowled Kaeya heavily.
"Very happy, baby."
Tartaglia complied with something better, entering Kaeya with a swift thrust of his hips forward. His dick was already slick with precum.
And Kaeya howled from still being unprepared, back arching off the desk and limbs scrambling behind the harbinger's back. He felt so full and sated that it was impossible to do anything else other than to press himself more keenly against Tartaglia.
He stared up into the harbinger's eyes.
Tartaglia was smiling at him, a rosy flush on his cheeks. His eyes were tender as he wrapped a hand around Kaeya and began pumping slowly. The affectionate curve of his lips deepened as he thrusted into Kaeya, making sure to drag his cock along his prostate and make Kaeya tremble and groan each time.
"Argh," moaned Kaeya, a dribble of saliva falling from the corner of his lips. A minute part of his brain dimly registered that they had been at it for the past twenty minutes. Yet it had felt like an hour, and he wanted it to last forever.
"Fuck me," whispered Kaeya, as Tartaglia resumed his madddeningly slow pace of stroking and thrusting.
"Harder!" he cried out desperately, and Tartaglia finally complied, bending him further into two as he loomed over him. The action almost pressed him against Kaeya's chest, and up close, he could see tears clinging onto the Calvary Captain's lashes.
"Have... you been waiting...for a long time, baby?" the harbinger disastrously crooned while thrusting into him wantonly.
"Yes," mumbled Kaeya, groaning when he wasn't speaking, "Just… go on. Snap me into two. Seed me, Fatui lover. Ah...ah!"
Tartaglia latched onto his nipple, swirling it around thoroughly with his tongue. It tasted salty and it was taut, being an egregious zone and being surrounded by Kaeya’s honed pectorals. At the same time, Tartaglia pumped Kaeya hard, thumbing the head of his slit skillfully. The hot length in his grip throbbed and twitched, completely lubricated by its own precum.
All that coming from his hotly blushing, gorgeous Cavalry Captain. Who had never acted so docile before until tonight. Tartaglia should have known how sinfully rewarding this was. Kaeya’s eyes were glazed all over, and his slack mouth gave the appearance of one so thoroughly immersed in pleasure that his sweat-plastered, messy locks only added to the appeal.
Tartaglia slammed his hips forward frantically. Kaeya was resplendent. He was mewing and moaning, all control placed in the hands of Tartaglia. His face was so flushed that its redness on his dark cheeks could be seen.
For the second time, Kaeya came first, cum spurting out like thick ropes of white. It splattered against Tartaglia's stilling hand, against his muscular chest, and onto Kaeya's toned stomach.
With a luxurious, breathy groan, Tartaglia thrusted into him as deeply as he could, before his seed came rushing out like a tap.
A moment passed before Tartaglia pulled himself out. Kaeya was whimpering, begging to be cradled and embraced. He gave a half-sob before dissolving into weak chuckles.
“Oh, my poor baby,” whispered Tartaglia, supporting Kaeya to a seated position and embracing him softly. His cock was still slick with his own cum, so he wiped it with his hand so that it would not rest uncomfortably against Kaeya’s stomach.
“Watch who you’re calling a baby,” rasped Kaeya, voice wet but euphoric.
“You’re tearing up,” commented Tartaglia against his shoulder, concerned and amused at the same time. “Did I do something wrong?”
“No, you did not,” Kaeya reassured, smiling against him.
“Then are you a baby?”
“Baby? Hah. I’ve just done something so sinful. I’m such a naughty adult.”
“How is us having sex sinful?” inquired Tartaglia, raising his head to stare directly into Kaeya’s eyes.
“Uh, well…,” began Kaeya sheepishly, “It’s nothing. It’s not like that at all.”
“Kaeya…,” said Tartaglia, frowning, “Do you not like yourself still?"
Kaeya’s eyes widened slightly. “Well, no. It’s just hard when I come from … well. It makes me emotional. I know I trust you with my secret. You don’t have to deal with it.”
They had been through many variations of this conversation before. Sometimes, like now, for instance, Kaeya was deadpan in his delivery, as if he spoke of something more innocuous than it was. And that was fine as he was trying to cope.
“Silly thing. I’ll deal with it because I want to see you happy.” Tartaglia flicked his forehead, earning another chuckle from him.
“Fuck you," said Kaeya, shaking his head happily, "And I mean it in a good way. You’ve got a good heart, despite what others might say. I love you.”
Kaeya was teary-eyed again, and Tartaglia was all sunbeams and joy inside his heart.
"I...love you too," he said impishly in return. "And if you're a sinner, I'm your salvation."
Kaeya gave a bark of laughter, naked body shaking against Tartaglia's chest.
"As if. Idiot."
