Why Childe never does undercover work

Summary:

Joining the Mondstadt Mafia was incredibly boring. Already this undercover job was a waste of time. A shame nothing could keep his interest

However, a certain Captain finds himself very interested.

Notes:

Beta read by Purple_Maknae7 and special thanks to Des and Nire for giving it a look over too!

This was a gift originally but that person turned out to be a cold hearted traitor <3 so it is not their gift anymore. Thanks for breaking my heart!

(See the end of the work for more notes.)

Work Text:

Boring. Irrefutably, unarguably, boring. 

 

Childe stared at the paperwork with a smoldering glare. Since when did mafia rookies do paperwork?? What happened to being expendable? Selling illegal materials? The fun stuff!

 

Childe groaned and held his head in misery. He didn't join the Knights of Favonius, Mondstadt's mafia, just to sit in an office all day! The only thing that kept him sane was the occasional burning of documents via Bennett! Wait. Speaking of which, where is his accident prone colleague?

 

Instantly the ginger perked up from where he was slumped on his seat. Where was Bennett? The smell of smoke confirmed his suspicion. With a gleeful smile he grabbed a stack of his paperwork and ran towards the scent. 

 

Childe slammed open a door and smirked at the chaos within. Fischl and Razor were desperately trying to put out a clearly in fire Bennett, his clothes smoldering with flames. Patting it our clearly wasn't effective as amusing as it was to witness Fischl's desperate attempts. 

 

Before Childe stepped in with his hydro vision, he gleefully tossed his papers onto the fire. Once he was sure the flames incinerated the stupid insolent documents, he finally summoned water and allow a giant wave to cascade on all members present. Fischl sputtered indignantly as her clothes were doused while Razor looked like a drowned puppy, his hair flat on his head. Bennett meanwhile was still laying face down looking worse for wear. 

 

"The Princesszin and Razor had no flames attempting to consume us! Why does the foul ginger of water ensure we, too, are flooded by your violent waves?"

 

Childe gave a sheepish smile at Fischl's unamused (and confusing) question. 

 

"Y'know I just had to make sure! As the only one with a hydro vision I'd be the one chewed out by one of the more senior members if all of you burned to death."

 

Childe walked over and crouched down by the limp body of Bennett and gave it an experimental poke. A quiet "ow" alerted him that he was still alive. Good. Childe owed the kid after being a convenient source of entertainment and ridder of paperwork. 

 

"Is Bennett okay?" 

 

Childe's heart melted as Razor asked with a very concerned expression. So cute~ he couldn't resist and stood up and gave the grey-haired boy a pat on the head.

 

"You know Bennett! He'll be better in no time!." He gave Razor his winning big brother smile and received a small one in return. Fischl also jumped in,

 

"Of course! Bennett is one of my most loyal subjects Razor! There is no way such a brave soul would perish from these pathetic flames! I give you my word as the Prinzessin."

 

A groan of pain and a signed thumbs up were valiantly given from Bennett at her words. The entire room immediately perked up.

 

"See, told you!" Childe smiled and reached to pick up the burned boy as gently as he could. It was time to head to the church for the nth time this week.

 

~

 

Deaconess Barbara was horrified to see Bennett's condition (no matter how often something like this happened) and immediately rushed to heal him. Childe left soon after knowing Bennett was in good hands

~

 

Childe finally made it back to the headquarters. The rather tall buildings arched over him as he entered. Internally he was relieved. Now he could beg some of the other members to hand him their hunting mission. Lucky~

 

He paused mid-way through his walk as his instincts tingled ominously. Dark empty blue eyes scanned his surroundings. What is setting his senses off...

 

clap clap clap

 

"An excellent effort to avoid your paperwork again, Childe. Are you going to pawn missions off of my men as per usual?" A cocky voice echoed from behind him... one he didn't recognize.

 

Childe turned around, alert, and faced a man with a darker complexion, dark blue hair, and an eyepatch. Those features could only be one person. The cavalry captain, Kaeya. Someone far above his station and frankly a person he should not be meeting. Now this, this was interesting. 

 

Childe smiled sadistically.

 

"Oh? I don't think I've met you before and you already know my name! Nice to meet you, Sir Kaeya."

 

Kaeya smirked at the knowledge he was recognized, icy blue eye analyzing the person standing before him. Childe held back a shiver. Despite the captain’s laid back demeanor, his gaze felt piercing. 

 

Ah how Childe wished he could fight him head on...

 

"Your name caught my ear as all of a sudden missions normally avoided were all completed. Imagine my surprise that after kindly asking my men, they all pointed fingers at a single rookie. Care to explain?" Kaeya asked as he stepped forward a few paces, closing the distance between him and Childe. His eye twinkled dangerously as he approached. 

 

Childe kept his easy-going posture and continued to smile at the captain. 

 

"Ah, well you see. I found myself lacking paperwork and I really do love giving my limbs exercise during the d-"

 

Childe paused as a sword gently kissed the front of his throat. Oh? What fast movements. As expected of the captain. Childe's smile didn't waver as the sword stayed put. His heart sped up in excitement. Would he get to fight Kaeya here?

 

He swallowed in disappointment as the sword moved away.

 

"Not even a flinch? Have I lost my touch now?" Kaeya chided, his grin a touch mischievous. "You have the gall to interfere with my men, rookie, and you don't even give me the satisfaction of watching you squirm. How disappointing." 

 

Childe opened his mouth to speak, but was interrupted by Kaeya.

 

"Follow me." Kaeya blinked slowly and honestly Childe couldn't tell if that was a wink or not. Regardless, he followed the billowing cape of the cavalry captain down the hall. As fun as fighting the captain would be, he has a job to do which, unfortunately, does not include that. 

 

A few members looked on in vague horror as the two of them walked down the halls. A few of them looked at Childe with pity. 

 

They reached a door at the end of the hall. Kaeya reached towards it and beckoned Childe to enter. The ginger enthusiastically walked in and took in the office of the Cavalry Captain. Plaques of Mondstadt stood around the room and flags were hung on the walls. The carpet below even had the pattern on Mondstadt below it. How patriotic. A large desk stood ominously at the front. Kaeya walked behind it and sat in the chair. Childe sat in the chair in front of the desk. The small thing paling in comparison to everything in the room. Is this a power play of some sort? To make him feel smaller?

 

"Well?" Kaeya asked, a grin perpetually on his face.

 

Childe just looked at him with confusion in his dark blue eyes "Well... what?"

 

"According to Noelle your paperwork these past few weeks have ah.. 'mysteriously' managed to find themselves burnt to ashes apart. Then you just happen to be free to take up the responsibilities of the men under my supervision which, mind you, is against my policies. Confidentiality and all that you know? "

 

Oops. He didn't realize it was that big of a deal to take those jobs off of them. Childe shrugged and leaned back in his chair as he met the captain's icy gaze. 

 

"Bennett's fire is pretty all-consuming. Plus is it that big of a deal? Your men don't want to hunt monsters all the time and I'm willing to do the job instead." 

 

The room's temperature dropped a few degrees. Childe shivered and watched the captain with narrowed eyes. Kaeya watched him back, not looking amused.

 

"You recently joined us... did you not? Do you think you hold the authority to make decisions of what you do on your own?" His voice was cold as he spoke. No semblance of the playful demeanor from earlier remaining. 

 

Ah. There wasn't really a good way to answer this. 

 

"Yes...?"

 

Hey, what can he say? He hasn't been a subordinate in a long time. Not that he was a good one during that time anyway...

 

Kaeya looked incredibly unimpressed at the answer. His icy gaze burned as he glared. Kaeya reached out and hovered his hand over the table, summoning his sword. Excitement raced through Childe's veins. Are they going to fight now? 

 

Instead he flipped the handle around to Childe. Childe titled his head in confusion. What?

 

"You aren't allowed to use your vision. Just this weapon. Bring me back the head of a mitichurl or... , well, I'm sure you can imagine things won't be pretty."

 

Ah! Now that he could do. Childe smirked as he took the sword from Kaeya. He gave a cheerful wave and proceeded to leave the office.

 

"You got it captain!"

 

He closed the door behind him and watched as a single icy eye observed his departure. 

 

*

 

As the door closed Kaeya couldn't hold it back anymore. He laughed as he ran his gloved fingers through his hair. How interesting! Childe didn't even show an ounce of fear. If the ginger really was a spy like his connections told him, he really is a terrible one. Oddly enough that makes him feel like a legit rookie. A very stupid one, but a real one at that.

 

Whether or not he is a spy... well~

 

Kaeya may as well have some fun with this.

 

~

 

Childe sat upon a pile of hilichurl corpses. A few mitchurls lay among the carnage around the absolutely soaked area. Head to toe he was absolutely covered from the chaos he caused. Childe groaned as he looked down at his outfit and the sword he was given. He was 100% going to have to clean up before returning to headquarters. Keeping his word to not use his vision meant using a stream. Childe followed the forest path until he came upon, not a stream, but a lake.This will do.

 

The ginger assured his Knights of Favonius issued outfit was thoroughly cleaned and the sword properly polished. A beautiful blade deserved the best after all. The weapon Kaeya had allowed him to borrow was truly a nice thing. Well balanced and high quality. Even though a single sword wasn't his normal choice, he was quite content with this fun. 

 

Childe wiped down the shining blue blade until it  again shone with bright light in the sun. Perfect.

 

He slung the head he had collected over his back. Ignoring the fact this defeated the purpose of cleaning his clothes. A little bit of a mess should be expected after all. 

 

Leaves crunched under his boots as he continued down the path back to headquarters. The sun gleaming in his ginger hair as he went. 

 

~

 

Finally, he had made it back. Several poor townsfolk eyed him in horror at the gruesome display on his back. Thankfully, no children seemed to have spotted him. Headquarters came into his vision and Childe eagerly entered the building. Now knowing the location, he ignored the curious looks he received and walked towards the room he now knew as Kaeya's office. A few of the members looked at him with clear suspicion, but when they noticed the sword by his hip they instantly reverted their eyes. Hmm…. the captain must have quite the reputation then if this is how they react to his sword.

 

Childe arrived at the imposing door and gave two clear knocks. A muffled "Come in" could be heard from the other side.

 

The ginger reached for the handle and entered the office for the second time today. Sunlight poured in from the windows and haloed the captain sitting at the desk. An amused glint in his eye as he took in the man entering his office.

 

"Oh, back so soon?" Kaeya asked in his perpetually playful tone. 

 

"Yep! I believed you asked for this?" Childe pulled the head off of his back and showed off his prize. Kaeya hummed, pleased.

 

"Well well, you finished that task rather quickly and without a scratch on you. I can't say the same for most of my men. A very... impressive feat. Especially for a rookie" Kaeya placed great emphasis on his last sentence. A smug smirk crossing his features.

 

Was he too obvious? It was just a mitachurl. Someone else could've easily done that, right?

 

*

 

Kaeya frowned inwardly.

 

Someone, especially a rookie, wouldn't have been able to do that. That speed was astonishing. He took a peak at the clock and noted it took around fifty-five minutes. That meant killing the mitachurl took fifteen minutes and most likely Childe walked twenty minutes to find one and twenty minutes to come back. Very fast. Faster than the majority of his men. Only people who could do it faster would be himself and a handful of exemplary individuals such as Acting Grandmaster Jean.

 

Just who was this "Childe" to be able to accomplish that? Did he get help from somebody else?

 

~

 

Childe watched Kaeya's icy gaze as it looked at him calculatively. What could be going through the captain's mind?

 

Did he screw up this early on? Crap, the Tsaritsa wasn't going to be pleased. To be fair, he wasn't the best at being undercover anyway. His usual job was to cause chaos, not to lay low.

 

Finally, Kaeya broke into a smile.

 

"Say... why don't you join my team, Childe?"

 

Childe's deep blue eyes widened in surprise. Him joining Kaeya's team? A surprise, but a welcome one. Better for information gathering and entertainment!

 

He returned a smile and replied, "I would love to."

 

Kaeya chuckled, clearly expecting that answer, and his icy eye dancing with mirth. The captain reached under his desk and pulled out a sheet of paper. A contract clearly written with a fine pen.

 

"Sign here and here, and be sure to read the clause on assignments. I'd hate to punish you for taking them from others again." The emphasis on the word hate gave Childe the impression that, no, Kaeya would actually be more than happy to do that. How exciting. Childe skimmed over that section, noted it, and went down to put his signature at the two spots. It was official now.

 

"Welcome to my team. I hope we get along well, Childe." Kaeya purred, his white teeth glinting as he smiled. That look sent a chill down his spine, but he couldn't find it in himself to feel any sort of fear. He was only looking forward to it.

 

~

 

Childe glared at the no doubt hundredth slime he had to obliterate. Of course Kaeya was a petty jerk and assigned him the most boring and mundane monster control missions. If this continued, he was going to walk into Kaeya's office for a real fight and blow his cover in the process. Which was honestly better than this mess. He grimaced at his clothes covered in slime condensate. Normally this wouldn't bother him, but at this point he thinks his clothes are more slime than fabric at this point. Damn that captain...

 

~

 

Kaeya eyed Childe's slime condensate saturated outfit with a smirk. Childe's grin turned slightly feral in response.

 

" Satisfied , captain?"

 

Kaeya chuckled,

 

"Oh? Is this not what you wanted? Killing monsters?"

 

The infuriating captain put his hand on his chin as he leaned forward. A clear mocking tone in his voice.

 

Out of spite, Childe flopped onto the chair across from the captain. He smiled in satisfaction at the subsequent grimace as the chair immediately began soaking in the slime. Childe just looked the captain dead in the eye as he shifted his body ensuring it was thoroughly covered. Kaeya's smile twitched, while Childe's only grew. Oh he was playing with fire right now. The captain looked like he was going to tear out the ginger's throat any moment now. Childe wished he would try.

 

"I like good fights, captain. Exterminating every slime in Mondstadt offers no challenge."

 

"Oh? Last I checked, as my subordinate, your interest in missions doesn't matter. You are in charge of listening to me and not complaining... no?"

 

Childe frowned, unamused. He grit his teeth in frustration and stood up and sat on Kaeya's desk in front of him. The captain glared at his actions.

 

"What... do you think you are doing?" His voice took on a falsely sweet tone, clearly angry behind the illusion. Childe swung his legs over until he was sitting with his legs by the captain and Kaeya's face right by his. 

 

"Childe, do you want to have my sword through you?"

 

"Will you? I'd love to have you try."

 

Kaeya stared at him in disbelief with an amazed smile on his lips. 

 

"So captain... What are you going to do about it?"

 

 As soon as those words left his lips a hand shot out and grabbed his wrist pulling him forward. Childe didn't resist the movement and allowed himself to fall from the table. The destination, however, he had not expected.

 

His lap, the captain's lap.

 

Childe’s mouth went dry as he stared into a singular icy eye. Slow warmth from another body seeping into him as he stays still from shock.

 

Slime began to soak the captain's clothes, but he didn't seem to care anymore. Eye gleaming with a new prospect. 

 

"Hmm last I checked I haven't used my vision on you. Cat got your tongue, Childe?" The captain purred. The soft breaths of his words tickled Childe's face and drew his eyes to the soft lips presented before him.

 

Kaeya wet his lips. Childe tracked the movement, fully enchanted. A knowing smirk crossed the captain's expression as he noticed Childe's gaze.

 

Those lips neared his own. All Childe had to do was lean in slightly and they would meet.

 

He leaned-

 

And they met. 

 

Gloved fingers pulled at his hair forcing him to take a better angle as their mouths connected. A bold tongue asked for entrance and who was Childe to deny it?

 

Their lips danced as they panted into each other's mouths. Childe’s fingers reached to grab onto Kaeya, but gloved hands forced his hands behind his back. Immediately Childe fought against the captain's grip, his instincts kicking in, but ice crystals forming on his skin quickly warned him not to struggle any further.

 

A laugh escaped his lips as he felt icy shackles tie his limbs together. Adrenaline coursing through his veins as his hands jerk and test the strength of the frozen water. The shackles do not give.

 

"How cruel captain. Is this how you treat all of your subordinates?" Childe muttered as hydro coalesced from his fingers

 

"Oh no Childe you are an exception. After all, I only treat spies this way."

 

Childe laughed again with a bloodthirsty smile crossing his expression. He licked his lips before replying, "A spy reall-"

 

Fingers pushed at his lips forcing him to be silent. He shuddered as Kaeya leaned to his ear and whispered, " Do not lie to me ."

 

A loud crack sounded.

 

Hydro flashed as ice shattered, echoing loudly across the room. Frost and water clashed as a hydro blade met sword. Kaeya and Childe stared each other down with their respective weapons in hand and smiles on both of their faces.

 

With eager steps, Childe brought his blade down for a slash, summoning one into his other hands. Skillfully, the captain parried every blow of his twin blades with bursts of ice, one of the blades shattered at the impact.

 

A laugh escaped Childe’s lips as the ice shards fell sadly from his hand. The sword slashed down at him in response, aiming for blood. With well practiced moves, Childe dashed to the side with his bow summoned and aimed. An arrow sliced through the air, narrowly missing the captain. 

 

A mocking laugh left Kaeya's lips, the room itself turning a frigid temperature. "So, Childe . Care to tell me where you've learned such impressive skills or shall I ask your body?"

 

Without answering, Childe sprinted, water blades shimmering in hand. "Don't worry, I'll be sure to let your corpse know first, captain."

 

Frost exploded through the room as another collision shook the floor. Childe winced. There is no way the whole building didn't feel that. He pursed his lips. 

 

Kaeya didn't give him much time to think. The captain’s blade danced with him much too quickly to lose himself in thoughts. Each collision caused his heart to sing in joy. Now this is what life is for. Fighting delicious enemies like this. 

 

Hydro coalesced around his fingers, glowing brightly in the darkened room. A shield formed at the next impact, causing Kaeya to grit his teeth as his sword struck something solid. Childe smirked. An icy blue eye glared at him coldly, before suddenly disappearing entirely. Childe blinked. What…?

 

Only quick instincts saved him by alerting him of the sword about to pierce through him. He found himself face to face with the captain he could've sworn wasn't behind him a literal second ago.

 

He smiled. How interesting. 

 

They continued to trade blows, ice occasionally clashing against him with each hit. The two of them shared a thrilling dance of dodging, striking, and blocking as blood rushed rapidly through Childe's body and  adrenaline continued to flood his veins. 

 

The captain was ruthless. Each hit was sharp and precise with arm numbing strength hidden in his lithe frame. However, Childe was no pushover either. Every strike of his blades proceeded to move faster, carried on by a deep sense of bloodlust and strong desire to win. Their weapons clashed and they found themselves face to face, both of them flushed and panting slightly. 

 

Childe found his gaze lowering to those soft lips amidst their clash, the smirk on them made them seem so… enticing. His brain still remembered how nice they had felt.

 

He shook himself out of the momentary distraction. Now was not the time.

 

With a flick of his wrist electro surged around him, electrifying the air and pulling an excited laugh out of the captain. 

 

"Fatui? How exciting. Don't let me get bored now, Childe." Kaeya teased, his weapon still firmly pointed at him.

 

"I wouldn't dream of boring you captain. Just make sure you don't bore me ."

 

Electricity arched across the room as Childe swung his polearm, the very air vibrating from the power. However, Kaeya was quick, at the first strike a shield sprung up around the captain. It's hexagonal surface deflecting the bolts attempting to pierce it with ease. 

 

Childe growled as he realized how ineffective his attack was, with quick thinking he sprinted forward with electro powering each step.

 

His power surged as he struck. The shield shimmered angrily as electricity squirmed through its cracks, slowly shattering each weak point.

 

With a yell, Childe broke through with a triumphant smirk as he grabbed onto the captain, pinning him to the ground. His hydro blade surging ominously at Kaeya's throat. 

 

A single icy eye looked up, amused, causing Childe to feel momentarily distracted. He frowned as he tried to figure out what had made the captain still so cocky .

 

Then he realized what position he had pinned the body beneath him in. Faces metre inches from each other and crotches lined up. Childe bit on his lip as his thoughts surged. His brain struggled to separate his bloodlust from lust and the captain wasn't helping as he smirked up at the Harbinger. 

 

His knee sneakily moved between Childe’s legs, attempting to brush against the bulge there. Childe's arm shot out and grabbed the offending appendage. His dark eyes flashing dangerously.

 

He continued to hold onto the captain's leg. His brain is warring with itself. A part of him wanted to let the captain continue what he was going to do while the other wanted to slit his throat. 

 

Kaeya watched the debate going on within the man on top of him with a chuckle. If Childe wasn't going to make the first move…

 

He would. 

 

He pulled the conflicted ginger to his lips, nipping at them aggressively to spur Childe in action. Kaeya purred as he felt him respond, Childe instantly reacting to his challenge. The kiss deepened as tongues soon began to intertwin, both of their bodies instinctively moving closer. 

 

Kaeya shifted under Childe, the leg not pinned by the ginger sneakily moving upwards. He grinned in the kiss at the moan Childe choked out as his leg rubbed sensually at his clothed bulge. 

 

Childe pulled away as the sensation continued with his dark eyes sparkling hungrily. 

 

"You shouldn't have done that, captain. Not when I have you like this."

 

Kaeya merely chuckled in response, "Perhaps you haven't considered this is a situation I desire, Childe. Second drawer on the left. Don't keep me waiting."

 

Childe just looked down on him in surprise. The sudden realization the captain has supplies for sex in his office bringing a wicked grin to his face. He stood up from Kaeya and reached the desk, rummaging through the drawer and smirking as he found condoms and lube.

 

"Get busy here often, Captain? "

 

"Only with the handsome spies. Do be a good lay for me, would you Childe? I would hate for my final memory of you to be pathetic now."

 

Childe's eyes darkened further. His teeth ripped at the condom package as he once more loomed over Kaeya, pinning him in place. His gloved hands eagerly sought out the complicated belt for the captain, unfastening it as fast as he could.

 

Kaeya's icy eye twinkled in amusement at Childe’s haste. Feeling a bit generous, he worked on Childe's still slime-covered pants as the man undid his. He licked his lips as he peeled his way to his prize underneath those dirty clothes. It was a shame Childe didn't have similar taste in tight clothing as himself. The slime would've looked quite appealing on those. That and these gems here would be quite worthy to be shown off in them. 

 

Kaeya cupped Childe's balls and began to admire the long shaft now revealed to him.

 

"No ass to speak of, but you were hiding such a delectable treat, Childe. To think I thought your lust for blood was a means of compensating for something."

 

The ginger sent him a smoldering glare for his bold words. 

 

"You have no right to talk about the lack of a big ass captain. Pot calling the kettle black and all." Childe shuddered as Kaeya continued his actions, bringing tingles of pleasure across his body. 

 

"So you were checking me out in the hall. How bold."

 

Childe just sent him an unamused look before lifting the captain and finally pulling down his criminally tight pants. He was awarded with the sight of the most scandalous underwear he had ever seen. This doesn't even cover anything?!

 

He stuck one finger through the band holding it and just looked in disbelief as a gorgeous view instantly was in full view. 

 

"C-captain, do you always wear underwear like this?"

 

"Hmmm? What's wrong, never seen a thong before, Childe? I find them quite comfortable actually."

 

Childe just shook his head at the captain's shamelessnes. He reached and pulled the underwear off in quick movements before pouring lube liberally on his hand and moving towards his prize. He circled Kaeya's hole and slowly pushed in with a finger. 

 

As he worked Kaeya moved forward and grabbed him for another aggressive kiss, teeth nipping and tongues fighting for dominance. He hissed softly as Kaeya's clever hands fondled his dick, tracing the tip before giving him a few firm pumps. 

 

 Childe pressed himself further into the captain even as the delicious sensations attempted to distract him. He forced another finger in, scissoring him slowly. 

 

Finally, he hit Kaeya’s prostate. The captain moaned and eagerly licked deeper into Childe’s mouth. The sound of Kaeya's moans sent sparks of arousal crackling throughout his body. He growled softly and sped up his actions, desperately kissing the captain as he fingered him further. 

 

He gasped as Kaeya continued to stroke his cock. Even as he abused the man's prostate, he still had a steady grip that continued to pump Childe, drawing soft sounds from his lips. 

 

Childe could feel his need increasing by each second, his eyes narrowing and movements getting more desperate, with one last long and mind blowing kiss, he pulled away panting. 

 

He was treated to quite the sight. 

 

Kaeya looked so beautiful beneath him- hair messed up, bloodied lips, and saliva falling from his mouth. His cock stood proudly begging for attention while his eager hole was prepped and ready. Waiting for him.

 

Childe licked his lips eagerly, not willing to wait another moment. 

 

His cockhead kissed Kaeya's hole as he slowly pressed in, the captain tensing slightly beneath them. The twin sounds of their hot breath echoed loudly within the room. Slowly he forced his way further into the tight fiery heat, Kaeya watching him with a glazed eye as he steadily began to fuck into him properly.

 

Childe pulled himself out and quickly slammed himself back in. A soft cry left Kaeya's lips and a deep groan escaped his. 

 

"K-Kaeya-" he sucked in a sharp breath as the heat clamped onto him, sending shivers of heavy need down his spine. The captain was so tight. It took everything in his power not to give in and thrust wildly. 

 

He startled from his steady thrusts as fingers yanked his hair, forcing his lips to connect. Childe groaned eagerly and licked between them. A wet and needy dance between the two opposing parties. 



Every thrust began to pick up speed. Childe could feel himself getting ever so closer to that tasty edge, every tantalizing sound leaving the captain's lips sending him even further. Only a little bit more-

 

"Ngh, is that- the best you can do, Childe? 

 

Childe narrowed his eyes at those words, a growl leaving him. Kaeya wanted a challenge? The temptation to use that form was near overpowering, but his senses won out. 

 

It would be too difficult to flee weakened even though the captain would be so well fucked. Thankfully, boredom and long travels on Fatui business had given him plenty of time to experiment.

 

He had just the trick up his sleeve…

 

The first one was small as it formed. The smallest of tendrils slowly slithering across Kaeya's leg. He jerked in surprise, eyes widening. 

 

A gasp forced its way out of his lips as more sensations suddenly joined in. The captain leaned forward and was treated to the sight of tentacles formed of pure hydro wiggling on his body.

 

"Oh my. A clever trick." 

 

Childe hummed in agreement, his eyes sparkling deviously as more began to form behind him. 

 

Kaeya hissed as a few moved towards his hole, pushing at the rim already stuffed with Childe's cock. A couple others wrap themselves around Kaeya's limbs. 

 

"Thought you might have something for restraint, captain . You did handcuff me after all."

 

Kaeya laughed breathlessly, disbelief in his eye that quickly turned into surprise as another slippery sensation touched his rim. He groaned lowly as Childe hit his prostate, the feeling nearly distracting him from the other object asking to gain entrance.

 

"A-Another, how bold." 

 

Childe just chuckled darkly in response, continuing his thrusts that were forcing pleasure throughout Kaeya's body. 

 

The tentacle wiggled and stretched until it breached. Quickly squirming it's way to pressing directly inside, a scream leaving Kaeya's lip. He looked lost in the pleasure coursing through him, eye glazed and the sudden sensations. 

 

What a lovely sight. 

 

Childe continued his deep thrusts, ensuring the tentacles kept the captain well occupied. Stroking his sensitive spots and causing him to writhe at the feeling. Drool dribbled down Kaeya's chin as Childe watched bewitched. 

 

The captain was a moaning mess. All his previous bravado gone. Such an arousing thing to witness. Childe gripped Kaeya tighter at his next thrusts groaning at the tight, warm, heat. His edge rapidly approached him once more, but he wasn't alone. His eyes twinkled deviously as he watched the captain squirm below him, cock dripping, ready to be spent. 

 

"Not so cocky anymore are we, captain?"

 

His only response was needy moans as he continued to take Kaeya apart. The captain spilled his seed across his chest, finally falling off the edge. The sight alone was enough to send him curtailing off the edge by his side. 

 

Childe groaned. Body going limp and tentacles evaporating. Kaeya was panting heavily below him with a dazed gaze. Still clearly recovering. Which meant that was his cue to leave. 

 

Without further preamble he threw on his slime crusted clothing and made his way to the window. Hydro cut neatly across the glass and allowed him to form a hole to escape from. Perfect~ 

 

He grasped the sides and pulled himself up, but before hopping out, peers behind him and stiffens. Kaeya smiles.

 

"Leaving so soon?"

 

Covered in cum and completely naked, the man still has an aura of power as he watches Childe, a playful smile on his lips, "We will meet again Childe. Or do you prefer Tartaglia?"

 

Childe laughs openly, a predatory look in his eyes. Kaeya’s gaze replies just as sharp and piercing. 

 

"Until we meet again, captain." With a wink he throws himself out of the window, neatly landing down below.
