“Come on, Xiansheng… We haven’t done anything in forever.” Childe whined, “and how am I supposed to work with this..?” he leaned back in his chair, and gestured lower, to the growing tent in his pants.

Zhongli sighed, carefully leaning against the desk, trying to be careful to avoid crumpling any of the scattered paperwork. “Childe, I hardly find it proper to do this sort of thing in your place of work…”

Childe pouted, tugging on Zhongli’s coat gently. “C’mon… This is my own office- the door is locked, and no one will come in.” The consultant averted his gaze from the harbinger’s puppy eyes. “Plus…” Childe murmured, standing up from his seat and leaning over the elder’s slender body.

“If I’m remembering correctly, you really liked it last time.” he whispers into his ear, causing Zhongli’s cheeks to turn a pale shade of pink. Zhongli recalls the last time he visited his boyfriend at work, and how he walked with a limp the day after. The memory makes him fidget against the desk, lazily running a finger across one of the many miscellaneous papers.

He thinks about the feeling of his lover’s hands around his waist, pulling Zhongli’s form down against him, grinding into his core, and feeling his release spread deep inside. All on this desk… It feels like it was so long ago, but he remembers it like it was only yesterday.

“I’m right, aren’t I?” he runs his hand down the front of Zhongli’s torso, bringing the dazed man out of his daydream, stopping just above his crotch. “After all, you’re hard too, aren’t you?”

Amber eyes gaze shot up to meet blue, fiercely blushing once he realized just how close they were. “C-Childe… I..” His words fall short, as a gloved hand cups his erection, causing him to let out a shaky exhale.

Childe leans into Zhongli’s neck, licking a stripe up the side, before sinking his teeth in, sucking hard.

“Childe… T-Thats enough.. Ah..!” Despite his protests, the ease at which Zhongli becomes worked up over Childe’s every touch and caress makes him quiver with heightened anticipation.

“Xiansheng…” Childe whispers, “Won’t you taste me?”

———

“Y’know… no matter how many times i see it, I’ll never get tired of this view…” Childe smirks. Zhongli is slotted between his legs, sitting on his knees on the ground in front of his chair. He has a small pout on his lips, but is already working at unbuckling his belt as Childe runs a lazy hand through his dark brown locks.

As soon as he works his pants down, Childe’s cock springs out, pretty much slapping Zhongli in the face. He flinches at the contact. The harbinger chuckles, gripping the base of his cock and pressing it against his face properly, letting a bit of precum drip onto his cheek.

“Hah… fuck, even without trying you’re so erotic, Zhongli.” He carefully taps the head against his soft lips.

“Now, be a good boy and open.”

The words of praise send heat straight to Zhongli’s dick, making him throb. He carefully kisses the tip, before slowly lowering his mouth onto it. He takes special attention to the spot right below his glans, already knowing how sensitive this spot is for Childe.

This elicits a hiss from the harbinger, making him buck his hips up into Zhongli’s mouth, effectively rubbing the length of his cock across the consultant’s hot tongue.

Zhongli notes the salty taste, before closing his eyes and tucking a loose strand of his bangs behind his ear. He carefully begins to slide his tongue along the underside of his length, bobbing his head up and down slowly.

Childe is eagerly watching his efforts, gently panting as he tries to avoid fucking up into the elder man’s mouth too soon. Childe is being generous with his patience, as Zhongli’s extra long tongue coiling itself around his dick is making him grip the arm rests so hard his knuckles turn white.

“That fucking tongue… fuck, it’s a blessing.” Childe whispers, slowly raising his hips up to gently press against the back of his throat, before lowering back down. Zhongli blushes again, before beginning to move his head up and down a bit faster, sucking and licking with fervour.

“Mother…fucking… ah… dragon tongue…” he grins, rolling his hips into the wet heat of Zhongli’s mouth.

Childe let’s his head fall back, letting himself get lost in the bliss that is the ex archon’s mouth. He’s practically moaning when he hears a frantic knock at his door. He jolts forward, watching as the door handle begins to turn. Zhongli’s eyes widen, looking up at the harbinger with a mouth full of dick, and the fear and concern in his eyes makes Childe throb. He puts a finger to his own lips in a ‘be quiet’ gesture, before quickly tucking the consultant under his desk, taking care to make sure his mouth remains where it is.

By the time the door is opened, Childe has resumed his identity as the 11th Fatui harbinger, pretending to read some random papers on his desk with a look of boredom. Ekaterina walks in, excusing herself before beginning to explain whatever debt collection required a debriefing. He carefully lifts his gaze from the papers to the fatui worker standing in the doorway.

Tartaglia takes careful consideration to look like he’s fully immersed in whatever the fuck she’s talking about. But all he can think of is the feeling of Zhongli’s soft, wet tongue against the underside of his cock.

The consultant has frozen, unmoving. He can hear his heart pounding in his chest, nerves of nearly being caught making him throb. He can feel precum leaking from the tip of his cock, making him shift his thighs uncomfortably.

Zhongli is taking conscious efforts to avoid moving, not wanting to give anything away. He tries to ignore the overwhelming presence in his mouth… but can’t. The weight of Tartaglia’s thick, heavy member resting on his tongue is making his head feel fuzzy. He gently adjusts his tongue, hoping for more of a taste, and is greeted with a throb. Every slight movement of his tongue makes the harbinger’s cock twitch in his mouth. Zhongli’s face heats up at the reaction he’s able to draw from Childe while he’s trying to remain in ‘work mode’.

Zhongli’s ministrations do not go unnoticed. Childe has a white knuckle grip on his arm rests again, using all of his strength to avoid letting anything slip. He nods and gives simple “Mhm, yep, yeah. sure.” answers, hoping to indicate his mutual desire for the agent to know he’s listening, but also that he wants her the fuck out of his office.

Either the agent is stupid, or just does not care. She continues her rambling while Childe is screaming internally for Zhongli to just sit still.

Of course, Zhongli can’t hear those silent pleas, but he makes an effort to stop anyways, once he looks up and sees beads of sweat on Childe’s iron grip on the armrest. He resumes a patient sitting position.

That is, until his leg starts to fall asleep. He winces, and slowly, so slowly, begins to try and shift his legs out from under him…

Ah… his foot gets stuck on the tail of his coat, and he stumbles.

And ends up falling straight into Childe’s crotch.

His eyes widen as he feels the tip breach the back of his throat, sliding down almost effortlessly.

Childe’s eyes widen, feeling a sudden unmistakeable tightness around the most sensitive part of his dick. He bites his lip, desperate to contain the urge to moan—

And then he feels Zhongli’s throat contract as he swallows around his girth.

Childe’s fist makes abrupt contact with the top of his desk, echoing a loud thud.

The agent stops speaking.
Zhongli does not move.

Childe is shaking.

“Ekaterina…” he whispers.

She blinks. “Y-Yes?”

“We can continue this later. Please. Get out of my office.”

With a quick nod, Ekaterina apologizes before ducking out of the office, closing the door behind her.

Childe let’s out a noise similar to a growl, pulling his cock out of the tight heat of Zhongli’s mouth, leaving the consultant to stare up at him wide eyed, mouth agape.

“Xiansheng.” he speaks firmly, but the quiver of arousal is detectable despite his efforts to conceal it.

“Open wide.” He grips the base of his cock, dribbling precum onto Zhongli’s lips.

The consultant honours his command, opening his mouth wide. Hearing his lover’s stern voice does things to Zhongli.

And seeing Zhongli oblige so easily does
amazing things to Childe’s dick.

With a slow, calculated thrust, Childe sheaths his entire length within Zhongli’s mouth. He pushes his hips forward with a deep groan, feeling the tightness of the older man’s throat around the tip of his cock as he bottoms out.

“Fuck… Xiansheng.. Your throat is so fucking tight. You take me so goddamn well.”

Zhongli is frozen in spot, listening to the younger man’s praise fills him with a sense of pride. Encouraged, he begins to move his head up and down, just for a moment, before Childe grabs the back of his head with two hands.

They make eye contact for a moment, and the ginger flashes him a knowing smirk. Zhongli has but a moment to prepare before Childe starts using his head as leverage while he fucks into his throat with vigour. He lets out a happy sigh, feeling the tight grip of Zhongli’s throat combined with the slick heat of his forked tongue.

Zhongli has no choice but to accept the fast pace of his thrusts, but they only serve to make him throb in anticipation. It takes everything in him to not gag on the harbinger’s dick, desperate to take all of his lover.

Childe’s hips begin to stutter, his breaths becoming ragged as he ruts deep into Zhongli’s cavern. He’s close, they can both feel it.
“Ah, Zhongli… I’m gonna cum…~”

With a few more aggressive thrusts, he pushes deep into Zhongli’s mouth, past his throat, and cums. His dick pulses, his hot seed flowing straight down Zhongli’s throat. He pulls out, allowing the last few squirts of cum to coat Zhongli’s lips and tongue.

“That’s right, Xiansheng… swallow.”

Zhongli obeys, licking his spend from his lips and swallowing, making sure to open his mouth wide to show his lover that he swallowed the whole thing.

Childe grins, panting in the afterglow of his orgasm. “Good boy.”

Zhongli moans at the praise, shifting uneasily on his knees.

Childe looks down at his lover, knowing from his body language alone that he is aroused. He leans forward, kissing Zhongli deeply before carefully pressing the sole of his shoe into the consultant’s strained erection.

“Ah..?” He moans softly, bucking his hips into the much needed pressure. “Childe.. you… haah~”

The ginger licks his lips, before carefully lifting Zhongli up off of his knees, placing him carefully on his lap. “You didn’t think I’d leave you like this, did you..?” he chides, leaning into his neck and peppering it with kisses and gentle bites.

Zhongli’s face heats up again, as he feels his lover’s hands rubbing up and down his body, gently grazing his obvious arousal.

“I… I was unsure… I mean.. Someone literally walked in on us, Childe.”

“So?” the ginger continues nipping and lapping at his neck, kissing his jawline and suckling it softly. Zhongli’s head feels fuzzy from all this, his rational mind telling him to put a stop to this, but the fire in his groin makes him tilt his head back, allowing even more access to his slender neck.

“Ah..~ C-Could we lock…it?” he whispers, lifting a hand to cup Childe’s face lovingly.

“Mm… yeah, we could…” he pauses, leaning back and looking into golden eyes.

“But I’m positive no one else will come in here. Besides… Isn’t it exciting?” he licks his lips, lifting Zhongli off his lap and laying him down on the desk, scattering assorted papers off of his desk.

“The idea of being caught?” His hands work at undoing Zhongli’s slacks, while the consultant covers his mouth to muffle his panting, and hide his deep blush on his cheeks. Every gentle graze against his bulge is torture, he’s sure Childe is doing it on purpose.

“The effort you have to make to hold your voice in…” A gloved hand slides up Zhongli’s long coat, sliding along his abdomen, before landing up at his chest, pinching a nipple hard. He writhes under the friction of Childe’s fingers, rolling his sensitive nub.

“All the ways you’ll be coming undone under me… All while everyone out there is working, blissfully unaware?” The idea, being phrased in such a way by his lover, makes heat churn in the pit of his stomach. “You love it, don’t you?”

He only realized Childe had worked the majority of his clothing off when he felt his legs being lifted and placed on the harbinger’s shoulders. Zhongli gasps, arching his back as he feels Childe press a finger against his rim.

Just barely prodding the entrance, teasing him even more, makes Zhongli moan, softly.

“W-Wait.. do you have-“

He’s interrupted by the desk drawer being opened and rummaged through frantically, before Childe presents a small bottle to him.

“Tadaa~” he jokes, popping the lid off and pouring a generous amount onto his fingers. In a quick movement, he’s placed the lube back on the desk, his still-gloved fingers already pressing against Zhongli’s soft heat again.

As the first finger breaches his rim, the consultant bites his lip to hold back a moan, willing himself to avoid thinking about the chance of people walking in. Not good, because it’s now all he can focus on… and he goes silent.

The lack of reaction has Childe momentarily concerned, before he looks at Zhongli’s face.

His brows are furrowed, lip being bitten, hard, as Childe’s finger pistons in and out of his hole. Oh, he’s holding back. He’s doing his best to be quiet and it’s so, so, cute.

In an attempt to undo him, Childe inserts a second well lubricated finger. Zhongli’s eyes snap back open. “Ah-?” he whines, licking his lips as his lover’s fingers begin to scissor him open. No fair, he thinks. Childe already knows all the things that can make him go wild, how is he supposed to keep quiet?

The harbinger’s smile is twisted with pleasure watching the archon continue to restrain himself. It’s fine, he can be strong for now. Since he plans on taking his sweet time with breaking his lover down, to a moaning, sobbing mess.

Tartaglia always gets his way, in the end.

Always.

With a third finger sliding in to join the other two, Childe uses his middle finger to press up against the spot he knows Zhongli loves.

“Haa!~? W-Wait… Oh~ Oh..~” The elder man can’t contain his noises of combined surprise and pleasure, gazing up at his boyfriend. His vivid blue orbs are hazy with lust, and he can see that Childe is hard again… Knowing his reactions are having an effect on him makes Zhongli’s cock twitch, dribbling precum from the slit.

“It’s okay, Zhongli. Enjoy it.” Childe continues to work his boyfriend’s hole, loosening it as he slides his fingers in and out at a steady pace.
“You did so well for me earlier, love. Swallowed every drop for me, didn’t you? A good fucking slut for me.” He presses another calculated finger against his prostate, making Zhongli arch his back in a way that makes Childe’s cock perk up even more.

“Hah~ I…I did well?” His face flushes at the praise. Childe nods, pressing gentle kisses into the elder’s neck, nipping and sucking him as he continues fingering him loose. “Yeah, Xiansheng. You did so fucking well for me. Took my dick so well, made me feel fucking amazing.” He pulls his fingers out carefully, plunging them back in momentarily before backing up to wrap his hand around his own cock and fist it slowly while staring down at his thoroughly worked up partner. “Didn’t even take your slutty mouth off my cock for a second to breathe, even after someone walked in. You’re amazing, Zhongli.” The archon trembles, looking hungrily at his lover pumping the length he so desperately wants to feel deep inside of him.

“Now, what do you want me to do for you, xiansheng? Tell me what you want. I’ll give it to you. Anything.” Childe licks his lips, excited to hear his lover beg.

Zhongli’s throat tightens as he reaches forward, placing his own fingers against his hole, thoroughly lubed up and ready. “I want it in here…” he pants, using his fingers to spread himself more. The visual has Childe’s knees nearly buckling.

“Be specific, Zhongli. Tell me what you want in there.”

“I want your cock in here… Please…. Shove your dick inside me and fuck me full of cum.~”

Out of all the things he expected from Zhongli in that moment, being that open about his wants was not on the list. It usually takes much longer for him to give in to carnal pleasure.

What a pleasant surprise.

“Oh? You want me to pump you nice and full?” Childe grins, still fisting his cock as he approaches Zhongli’s quivering form. He nods, a deep flush across his face.

“Nice of you to be so honest, xiansheng…~” Childe realizes he is still far too dressed, opting to hastily remove his jacket, and his red button up shirt, carelessly throwing them to the side.

He grips himself again, and presses the tip of his weeping cock against Zhongli’s hole, feeling it twitch against him. With a deep groan, Childe rubs himself up and down the slope of his lover’s ass, sucking air through his teeth every time the head of his dick catches against the rim.

Every few seconds he makes sure to gently press the tip inside, making Zhongli mewl while grinding his hips down, in a desperate attempt to coerce his boyfriend deeper inside.

“Mmh, Zhongli… I could cum like this. Just feeling your slicked up ass rubbing against my dick. You feel fucking amazing. Would you want that? For me to just use you to get myself off again?~” Childe would never leave him hanging, of course. But the threat is enough to make Zhongli whine and start pleading all over again.

“Ah, no.. no please…. put it in, Ajax.. please put it inside. Fuck me. I want to feel you deep inside… I want to… I want to feel your cum deep… all the way here…” He gently presses a hand against his abdomen, just below his belly button. He stares longingly at Childe. “When you go deep I can feel you all the way up here… It’s so good… please..” he whimpers.

Childe swallows, hard. There’s literally no way for him to win this when Zhongli’s being so lewd with him. He sighs, dick pulsing as he slowly presses himself inside. “I can’t deny you when you talk like that, can I?”

Zhongli’s toes curl in pleasure as he feels that delicious stretch from Childe’s cock sliding into him fully. He missed this. So, so much. Zhongli leans back, focusing on the slide and stretch, until his lover bottoms out, feeling his hips press against his ass.

Once Childe feels his hips flush against Zhongli’s, he grinds into him, making sure to press into his prostate with each shallow thrust.

“Ah, fuck… Zhongli, you’re so tight for me..~” he moans, slowly pulling his hips back, before slamming back into his heat. He continues his pace of slowly pulling out, allowing his partner to feel every inch of his cock little by little, and then ploughing home, the audible slap of their skin nearly echoing throughout Childe’s office. Zhongli’s hands jump to cover his mouth, knowing he’ll be unable to quiet himself as he knows this slow pace will not last for much longer.

At least, that’s what he thought. But Childe continues at a tedious pace, always making sure to snap his hips back deeply, but the slow drag when he pulls out is beginning to make Zhongli grow desperate. He squirms, arching his back, attempting to grind his hips down onto Childe’s dick, praying he’ll get the hint and move faster.

Childe merely smiles at him, licking his lips as he enjoys the view of Zhongli trying to spear himself onto his cock. Zhongli reaches above his head, gripping the edge of the desk for leverage, and starts rocking his hips more. He uses momentum from the desk to ride faster, harder, making his own cock bounce and slap against his stomach, leaving a wet spot of precum as he continues to revel in the pleasure that only Childe’s thick rod can provide him.

“You know, Xiansheng… You’re making this a little bit too easy for me,” Childe remarks. “I haven’t been moving for a while now, but the view I have of you right now… Gods, you look divine, Zhongli.”

His words instantly make Zhongli’s cheeks burn, a deep blush blossoming on his face. He ceases moving, and embarrassment makes him clench involuntarily. “I-I apologize… It.. You just feel so good, I could not contain…” Zhongli, the man capable of speaking words that flow as effortlessly as a river, is stumbling over himself. The haze of his arousal, the feeling of his lover sheathed inside him, throbbing against his prostate… It’s too much for him. Try as he might, he cannot seem to think straight.

“My, Zhongli. You’re still trying to hold up appearances? Even now?” Childe pushes his hips forward, eliciting a groan from the man beneath him. “I thought we already established that all you need to do is beg and I’ll give you anything you want. No need to be embarrassed.” Childe resumes his languid thrusts, clearly still wanting to tease him.

“Now if there was in fact something you want… Something.. more..” He punctuates his sentence with a snap of his hips, making Zhongli cry out loud, immediately moving a hand to cover his mouth. Childe quickly grabs his hand and intertwines his fingers with the consultant’s.

“Now would be the perfect time to ask, no?” He lifts Zhongli’s hand to his lips, pressing a soft kiss to his knuckles. “Before you’re too fucked out to speak, of course.”

Zhongli’s face somehow reddens even more, licking his lips before speaking; “I… I want you to pound me, Childe… I want to feel you deep inside, I want you to fuck me senseless.” Zhongli pauses, taking in Childe’s physical reactions to his words. His cock throbs, and a bead of sweat drips down his neck. He’s holding back… Just a bit more.

“I want you to fuck me so hard I can’t walk, I want to be fucked so nice.. Ah..~ and…f-full by your cock that I’ll .. Hhn..~ n-never forget the shape of you. I want to feel your cum deep inside me, filling me to the brim- a-and then I want more… Fuck your cum into me.. I want you.. to breed me, Childe.”

And just like the string of a bow, Childe snaps.

He nearly growls as he begins pounding into Zhongli’s ass, the sound of their skin slapping together reverberates around the room, accompanied by Childe’s feverish panting.

“Fucking hell, Zhongli~” He grunts as he delivers a particularly harsh thrust into his lover, sliding a hand down to grip his cock tight. “I didn’t know you had that in you, truly~”

Zhongli moans as Childe begins to pump his length in time with his thrusts. The stimulation on both ends feels so good, so right, there’s no way in hell he can hold his voice back any longer.

The consultant lets out a shrill gasp, as Childe’s movements pick up a steady, fast, and hard pace. Each rut into Zhongli’s needy hole punches a slutty moan from his mouth. Instead of opting to cover his mouth, he instead drapes his arms around his lover, pulling him in close and kissing him passionately. Zhongli slips a forked tongue into his mouth, mingling tongues, clashing together messily. Childe melts into the kiss as he strokes Zhongli faster, using a thumb to rub the slit, making him tense up briefly. Zhongli’s legs go limp, and they fall off Childe’s shoulders.

Childe separates the kiss, a thin string of saliva connecting them still. He carefully lifts Zhongli’s legs back up. He wraps his lover’s long nimble legs around his waist, hoisting him up off of the desk for a moment. Zhongli gasps, feeling Childe’s cock slip deeper inside due to gravity. Zhongli lets out a lewd moan into Childe’s ear, whoreishly bouncing his hips up and down, relishing in the feeling of his lover’s glans massaging his prostate from a new angle.

“Ah, Zhongli… You’re being so good for me. Keep riding me, just like that…” Childe groans, original intentions in lifting his partner fading from his mind as he allows his head to fall back, putting his energy into supporting Zhongli’s body.

Zhongli continues his work, bouncing happily with a blissed out expression. Although he’s not being stroked anymore, Childe’s hands now instead holding his ass and thighs spread wide, he manages to press his needy length against his lover. The slick stroke of his cock against Childe’s muscular abdomen makes him throb. He’s close.

“Ah… Childe… S-Sho deep~” he slurs, sloppily grinding his cock against the taut muscles. “Haah~ G-Gonna… cum..~”

Childe licks his lips, watching his lover writhe on him. “Cum for me, xiansheng.” A gentle command, but it does everything for Zhongli. With a few more gentle grinds, Zhongli’s vision goes white as he reaches his orgasm, clenching mercilessly around his boyfriend’s dick, releasing thick ropes of cum all over himself and his lover’s abs. Childe chuckles at the sight, taking in every choked sob that comes from Zhongli’s lips as he rides out his orgasm.

“Good fucking boy, Zhongli… You’re doing so well.” Childe praises. Zhongli collapses into him, panting. “Hhn.. Feels so.. good~” Gently stroking his lover’s hair, allowing Zhongli to rest against him, still reeling from his intense orgasm… Childe’s eyes widen as he feels Zhongli’s cock begin to harden again.

Damn this adepti body of his. So, so fucking lewd. So fucking perfect.

“Zhongli xiansheng… You are insatiable.”

Childe turns to his chair, placing Zhongli onto it so his back is against the seat. He unwraps the long legs from his waist, slipping his dick out. Zhongli literally sobs at the sudden emptiness, gaping hole clenching around nothing. The sight makes Childe smile. He lifts Zhongli’s legs up, up and up, until he’s nearly upside down, resting his legs on his shoulders once more- and plunges back in.

The punch of his cock makes Zhongli scream in ecstasy, toes curling, his ankles attempting to grab around Childe’s neck.

“Here is your reward, xiansheng. For being such a good cocksleeve for me.”

Zhongli’s tongue falls out of his mouth, he drools at the position. He has a full visual of his hole being stretched open by Childe. His dick throbs again, a dribble of white from his previous orgasm coming out. In his fucked out state, he thinks about the fact that Childe remembered his favourite position… It makes his heart pound. Childe cuts off that thought pretty quickly as he starts railing into him again, maintaining a sickeningly quick pace. Zhongli’s stomach churns, the cock inside him reaching much further than before. The lewd squelching noises that come from Zhongli’s thoroughly fucked hole make his ears burn.

Childe licks his lips, watching his boyfriend, already coated in cum, press against his own stomach- Childe can feel the press of Zhongli’s fingers against his dick as he slides in and out. Zhongli’s eyes are glazed over, but he appears to be smiling while looking at his belly.

A few moments pass before Zhongli manages to speak his mind-

“I feel it… up here~ I-I’m so full~”

Childe stills, processing what he just heard.

Zhongli looks up at Childe in a daze, clearly confused as to why he stopped.

“You… Gods… Zhongli, you are so. Fucking. Cute.” Childe punctuates each word with a harsh thrust, before resuming his previous assault on the former archon’s hole.

Zhongli let’s out a broken moan, eyes rolling back in his head, long tongue lolled out to the side, drooling all over himself. Childe’s dick can only get so hard, but Zhongli’s erotic body and facial expressions always test his limits.

“I fucking love you, Zhongli.” Childe pants, sliding his hands down his thighs, kissing them and nipping them before resting his hands to spread his ass further. He watches the pink hole spasm with each plunge into it, and he gets an idea.

He dips his finger into Zhongli’s cooling spend on his stomach, before rubbing the load around his rim. Zhongli cries out as Childe stretches him even more, a single finger breaching his rim alongside Childe’s already thick cock. Such a small amount more, but it makes Zhongli scream.

With alternating thrusts, his finger and hard length piston in and out of Zhongli’s twitching hole.

“Can you feel it well, xiansheng?” Childe coos, grinding deeply, rolling his hips as he slows his pace to a near halt.

“Haah! Y-Yes, oh Gods… It’s so fucking good, Ajax~” Zhongli cries out. “P-Please fill me, I want it so bad~ I love you so much~ F-Fuck, Ajax… I want your cum~ Please..~ Breed me full~”

Childe’s dick aches at the use of his real name. “Of course, my love. Make sure you take it all, okay? Make sure you keep my seed deep inside you.” Resuming his punishing tempo, he fucks Zhongli nearly into oblivion. The entire world could fall apart around them and they would not notice, completely absorbed in the passion of their love making. “I’ll breed you nice and full, just lay there like a good little slut and take it~”

Zhongli hisses as Childe delivers a particularly sharp jab into him, causing him to stop momentarily, nearly about to ask if he’s okay - until Zhongli glares daggers into Childe’s eyes, threatening him silently. “K-Keep going,” he whispers, trembling slightly. Childe gulps before placing a gentle kiss on his lover’s inner thigh, winking as he restarts his vicious pace.

“Got it~”

The two end up moaning carelessly, no longer bothering to think about their location. Nor about how many people likely have heard and know exactly what’s happening behind the closed door. All Zhongli can think of is being filled, and all Childe can think about is filling Zhongli.

As the harbinger nears his orgasm, his hips begin to stutter, clearly chasing his orgasm with fervour. Zhongli bites his lip, he knows what comes next-

“Ah, fuck, Zhongli… I’m cumming~” Childe’s hips roll deeply into Zhongli, halting only once he’s gone in as deeply as possible, letting out a languid moan as he spills over the edge, cumming deep into his lover. He curls forward over Zhongli’s trembling form, hips twitching with every pulse of cum that fills his lover.

“Hah, fuck… Zhongli, can you feel how deep it is?” Childe grins, satisfied with himself as he watches Zhongli melt.

“F-Fuh~ Ajax, I feel it… I feel your cum~ There’s so much~” Zhongli chokes out a sob, feeling his ass being flooded with cum. It’s so perfect, so full. He can’t help but lay there and take Childe’s seed, not that he would want it any other way. Before he realizes, a particular strong shot of cum hits his prostate in the most delicious way, and he’s met with blinding white heat- his pleasure mounting as he cums on himself again. Childe winces, feeling Zhongli’s heat spasm around his already sensitive cock, but he allows him to ride out his second orgasm as long as he needs.

“Good boy… Fuck…~” Childe pants, slowly starting to pull his length out of Zhongli.

With an audible pop, the consultant is left empty, he whines as his body goes completely limp, allowing Childe to lower his hips down and adjust him to a sitting position.

At this change of position, Zhongli whimpers as he feels Childe’s spend leak out from his hole. He reaches a finger down, trying to scoop it up and push it back inside.

The sight makes Childe swallow.

After allowing Zhongli a few moments to rest, Childe has mostly recovered from their… exercise. He’s redressed himself, after wiping Zhongli’s dried cum from his torso.

Now, to care for Zhongli.

He turns to face him. “Hey, xiansheng…” he trails off, noticing his lover nodded off in the chair. He can see Zhongli’s hole leaking cum, he’s still naked, save for the small blanket Childe draped over his shoulders.

The dozing image of his lover makes his heart swell with joy, he shuffles towards him and places a soft kiss against his forehead. Zhongli briefly rouses from his sleep, blinking at Childe.

“Hm…?”

“Here, let me get you dressed… I’ll take you home after, alright?” Childe begins to slide Zhongli’s button up his arms, buttoning it in the front. “Just let me take care of you.” he murmurs, continuing to redress the exhausted man.

Once he’s satisfied with the amount of clothes he’s gotten onto Zhongli, he shakes him gently. “Come now, Zhongli. Let’s get you to a nice warm bed, Yeah?”

Zhongli nods, rubbing sleep from his eyes before stretching his legs out, standing up for just a second- before they completely give out from under him, causing him to stumble. Childe catches him before he can even register he was falling, lifting him up and putting Zhongli’s arm back over his shoulder.

“Oh honey, I’m so sorry- Let me help you, yeah?” Zhongli winces at the thought of walking at all right now, but his worries are satiated when he feels Childe’s arm hook under his knees, lifting him to a bridal style carry.

Normally, Zhongli would be far too embarrassed to be carried in this manner. But his exhaustion from their activities makes him fall asleep in his lover’s arms, quickly.

Childe smiles and places a gentle kiss on his forehead, before making his way towards his office door- kicking it open.

As he steps out, he sees several fatui members standing there slack jawed. The sight of the 11th harbinger carrying an unconscious funeral consultant is not what people expected to see after all the noise they heard from outside the office. Ekaterina is among them, a furious blush plastered on her face.

Childe’s face darkens. “Don’t you all have jobs to do?” He sneers. In an instant, they all look away and scurry off.

Childe prays no one reported any of what they may have heard, or he’d have some serious explaining to do.

———————————-

Upon arriving at Zhongli’s house, Childe gently rouses Zhongli from his sleep once more, just to ask for his keys to unlock the door. Zhongli sleepily fishes through his pockets for the keys, inserting them into the lock and opening the door, all while being held still. Childe enters, still carrying the archon’s sleeping form towards the bedroom.

He gently places the man onto the blankets. Carefully, he begins to remove his clothing once again, before grabbing an oversized T-shirt that Childe recalls leaving here one of the first few times they spent the night together. Childe smiles at the memory, before slipping it over Zhongli’s head, pulling his hair out from the collar, laying him back down gently.

He looks so peaceful, so content.

Childe places gentle kisses to his boyfriend’s forehead, before slipping into bed with him, curling up behind him, wrapping an arm around him.

Zhongli hums, happily. Childe peppers light kisses against the back of his neck before they both drift off to sleep.

Childe’s last thoughts before he’s out like a light, are about the fact that neither of them showered yet.

Ah well, there’s always tomorrow.
