Countless droplets of rain rolled down the window as the former geo archon stared out into the night. It was comfortingly quiet, the pitter patter of water calming along with a side of osthmanthus wine. There were no disturbances, just the consultant and his beloved beverage. No annoying customers, no Hu Tao, and no rascal from Snezhnaya-

BAM BAM BAM

Zhongli’s gaze immediately shifted to the ruckus at his door. Who could be visiting at such a late hour, in the pouring rain, and banging the door so rudely? Such a pity his night of solitude had to be ruined for a while. As Zhongli made his way to the front, he could hear faint whimpers and pained moans on the other side. Almost sounding like a hurt, lost kitten. The rapid pounding against the door became increasingly wild, desperate even. While the moans grew in octaves too, some even sounded like they were calling for him. He recognized that voice. 

Once the lock had become undone, the door had dramatically burst open as a wet figure lunged straight at the consultant, sitting on top of him and grinding its ass right on his crotch, a satisfied and slutty moan immediately erupting from its throat at the action.

“Zh-Zhongli!! Hurry, I need you to fuck me right naahh- Xiansheng, p-pleeease!!,” the figure continued happily grinding down on Zhongli’s growing tent, drooling from the delicious friction it could get. It was bouncing erratically, splashing water and something white…? all over his floor and furniture. 

In a flash, the former archon had a bruising grip on its pretty hips, instantly stopping any more movement from the other. “Childe, what is the meaning of this? What has gotten into you?,” Zhongli looked up at the harbinger in slight bewilderment, the sudden friction stirring him up.

However, he didn’t get a proper reply as Childe began to whine and struggle against Zhongli’s unmovable grasp. “Nnhoo…! Nnghmm- nee-ed your c-cock insi~de!! F-Fill me with your cuuhm- I’ll do anything for cock ♡ - anythiing~~ ♡ !!” Childe continued to beg like a street whore, drowning out everything Zhongli was trying to convey to him. Tears began to flow from his already wet eyes in desperation. His restrained movements were becoming erratic too, making the consultant grit his teeth in irritation and his grip to double in strength. This old man has had enough.

A sharp slap across Childe’s face brought his struggle to a halt and a soft “ooh~ ♡ ” left his wet lips at the contact. “Have you calmed down a little now, Childe?” Zhongli brought his gloved hand up to the younger’s red cheek, gently rubbing at the smooth, tear stained skin, soothing the sting with his palm. 

Childe closed his eyes at the comforting touch and slowly nodded, coming back to reality for now. His face was flushed, harshly panting from whatever had affected him like this. Trembling not only from the cold, but also controlling himself from grinding back into Zhongli’s pants. With Childe now stilled for the meantime, Zhongli could examine the boy’s figure without disruption. 

Childe’s legs were weakly straddling Zhongli, his supple butt still on top of that bulge. His entire body was soaked wet from the pouring rain, most likely being outside for a while now as his clothes were slightly see-through. All of it disheveled even before barging into Zhongli’s apartment. The sleeves of his jacket rolled down his arms, exposing his pink dusted shoulders to the world. But that wasn’t all that became revealed. Now that Zhongli was staring directly at them, they became terribly obvious. 

Childe’s pecs were enlarged, looking like a soft pair of tits. His pink nipples were big and thick, dripping profusely with that questionable white substance coating the floor earlier. They looked full and heavy with milk. Each heavy breath and twitch Childe made would cause those milkers to jiggle in front of the other’s face, tempting the older to fondle and suck on them till they were bigger and swollen. It didn’t help how Childe’s arms pushed them together, squishing the plump tits lewdly. It was by all means, an erotic sight.

Brushing away the desire to touch Childe’s chest, Zhongli began questioning the other where he left off, “Can you explain how you came to be in this situation?” Zhongli’s eyes still managed to travel back to those titties even if he didn’t want to. The way those throbbing nipples kept leaking was just too… enticing. 

“Mmgh…training, a-and ngh…! Abyss maage… got hit- haah~, ch-changed my- b-body… I want- need!! T-To fill… aah!” The heat was coming back to Childe and all he wanted was to pull out the consultant’s penis to fuck himself on. 

Zhongli tightened his grip with the hand on Childe’s hip, the other softly caressed his face to sooth him. “I believe I understand. Why ask for my help though? Bubu Pharmacy should know of an effective remedy for… an issue like this…” Zhongli’s words died out as he caught sight of Childe’s breasts again. 

It took the other a while to respond, till he finally spoke with a light breath, “I-I didn’t know… who else to- t-trust…” 

Zhongli could make the assumption that the ever so prideful harbinger wouldn’t want his subordinates to see him in such a state. And with how Zhongli was the closest to him in a foreign nation, it made sense why he would go to him for help. 

“Hm, well then our best course of action would be to go to Bubu pharmacy tomorrow-”

“NO!! I cant- wait anymore, nnah hyaa~h, I need to g-get stuuhffed!! Nghh…fuck me♡ pump me full of your cum!! Need- inside, hurry pleease…!” Childe’s thrashing movements started picking up again, beginning to unclasp Zhongli’s belt to get into his pants, only to fumble with the clothing in a panicked frenzy. 

Zhongli quickly flipped the other onto his back while he loomed above the harbinger, finding it easier to pin him down this way. Their little tumble caused Childe’s jacket to ride up his stomach, revealing an intricate heart shaped symbol just covering below his navel. A sexy little thing it was, making the consultant take a large gulp. This kind of mark was…

“Childe, listen carefully. It seems as though you have been marked by a fertility spell. This type of elemental energy can cause transformations in the body in order to prepare it for fertilization. I believe some side effects from transforming can cause the leakage of fluids from erogenous areas, light fever and confusion, and an insatiable desire to partake and sex and breed. You are under its side effects, and the only way to stave them off is to-”

“What? Zhongli, I don’t care about- ughnng- j-just give me…!”

“pump you full of semen till you’re impregnated.”

“Yes!! ♡ f-fill me, nhah- give it alreadyyy- knock me up with your baby batter!!”

Zhongli scrunched his nose in frustration, although helping the poor boy would be most ideal, the conditions were quite extreme. After all, if he were to help him, it would lead to, well… having a child, which was not ideal. Zhongli would be lying if he said Childe’s little show wasn't getting to him, but there were more important matters to think about than his libido. “Please, calm down. You’re not speaking in the right mind because of the side effects. If I were to help you, it could lead to harsh consequences-” 

With what small light of clarity and strength he had left, the harbinger gripped Zhongli by his hair and brought him down till they were face to face. “Zh-Zhongli… does it look like I give a crap right now- ggh, I can d-deal with those later- so right now, just… breed me♡” the cheeky snezhnayan gave him a wobbly grin.

Zhongli took a deep sigh, a breath dense enough to  shake mountains, “alright then, have it your way.” He captured the other’s lips in a searing kiss, tongue and everything on the first go. Childe immediately gave in, letting the former archon explore every small crevice in his mouth, leaving nothing untouched by a long dragon tongue. He desperately wrapped his limbs around the other from finally getting the attention he wanted.

Zhongli pulled back from their sloppy kissing, only to dive straight into squishing those soft looking tits. Childe let out a squeal as some milk gushed out of his swollen nipples, the liquid trickling down Zhongli’s hand. The consultant began sampling Childe's leaking milk, finding it incredibly sweet and the texture smooth. Perfect for feeding young ones. Zhongli wasn’t a person for sweet things, but just the Childe-like smell was enough for him to crave even more of the delectable substance. Wanting to taste it from the source, Zhongli wrapped his tongue at one leaking bud and sucked, massaging the plump chest with his large hands to coax more out of it.

“ Oooh…! ♡ m-more, hahh~ so so good~~,” Childe softly moaned at the pleasure of his milk getting pumped out. Every now and then between his happy moans, he would encourage the other more with “ just like that”s and “so perfect”s . And so Zhongli focused on giving all his attention to the chest in his face. He quickly shifted their position so Childe was seated atop his lap, those tits bouncing till they were right back in front of his mouth. Zhongli continued where he left off, lovingly sucking the other teat till the liquid was flowing across his tongue. Everytime he would lap and flick around at Childe’s areolas, the thick nipple would spurt more sweet milk, showing the younger’s arousal, until Zhongli gave a harsh suck at the bud, earning a high pitched moan at the action. All the lewd moaning and sounds only made Zhongli’s dick harder.

The exercise became relaxing to the former archon, closing his eyes and enjoying the warm liquid on his tongue. Sucking like a baby till he was partially resting his head on the other’s massive chest which didn't even remotely fit in his groping hands. It seems even Childe was becoming more mellow and pliant from getting milked, his fluttered shut eyes and parted mouth expression a contrast to the crazed and restless one he wore earlier. They could just stay in this soothing activity forever, but Zhongli pulled away knowing they still had more to take care of.

The loss of a tongue licking at his tits led Childe to give a small whine. The harbinger started begging, trying to get that mouth back on his milkers, “did that taste good Xiansheng? ♡ hehe come on~ please put your hands on my fat tits again~~ suck on my leaking teats all you want, pretty pleaaase!!♡” Childe grabbed at his milk jugs, rubbing them together in front of the other’s face before bringing one dripping nipple to his own mouth. Zhongli watched in dark arousal as Childe’s boobs were big enough for him to milk himself. The way the younger’s shiny lips would mouth on a pink bud, then give a deep suck to the other nipple was tantalizing. He looked deep into Zhongli’s eyes with his half lidded ones as he gave his little show, never breaking eye contact. 

Zhongli snapped out of the trance the other put him in, remembering there were other things to look forward to as well. “Weren’t you the one who begged me to touch you down here earlier?” Zhongli’s hand slipped in Childe’s pants, his fingers lightly feeling at an already slicked up entrance.

Childe immediately bucked into those fingers, trying to get them inside his needy hole. “Mmmn~ yesh, touch me there too- ah, aah, need your thick fingers in my pussy ♡” He quickly became wanton to the touch, hands moving from his chest to plant in between his milky thighs, trying to bounce on Zhongli’s fingers. 

“It appears that your anus has been modified to be bred with the amount of slick you can produce now,” it was easy to shove two fingers deep in right away, starting a casual pace and getting the other used to the stretch. “This fertility spell makes your body ten times more sensitive and aroused in order to mate for long periods of time. It’s almost quite like adeptus fertility spells, however those don’t make the affected produce this many fluids.” The two fingers were accompanied by another thick one, rubbing Childe’s walls from different angles.

Childe rolled his eyes back at the stimulation, finally getting that sweet pleasure of something filling his insides. He tried shoving his hips back, wanting more than just fingers, anything that could gape him open real good. Zhongli could fit his whole hand in there and he’d still want more to keep him full. 

This didn’t amuse the consultant though, having his partner wiggling around as he pleases didn't sit well with his reserved manner. He’d just have to reprimand him to listen.

Slap

The sound echoed throughout the apartment as they both stopped. Childe’s asscheek was all red from the mean punishment, those thick fingers hanging still from his hole, unmoving. 

“As much as you are affected by that spell like a bitch in heat, I won’t tolerate your needy twitching and moving since you’ve interrupted my peaceful night. I will give you what you need, and you shall lay there and take it, understand?” Zhongli’s hand grabbed the other’s jaw, holding his mouth open while waiting for a response.

Childe looked at him submissively, speaking out a small yes as he slumped into Zhongli’s hold, clearly loving the rough treatment.

With that, Zhongli’s fingers resumed fucking him open. Squelching noises filled the air as they also synched with Childe’s filthy moans. A loud keen jumped from the younger’s throat once Zhongli hit a swollen bundle of nerves. Childe’s walls seized up, clenching as his prostate was attacked mercilessly by the former archon.

“There see, that was easy to find with you sitting still now,” his fingers doubled in speed, punching Childe’s spot with precision, even slowing sometimes to gently massage at the bump. “Your little cock is terribly leaking from just my fingers.” Along with making Childe a slutty mess, the spell seemed to have shrunk his cock to a pathetic size, only standing at a mere four inches. It seems there was no use for such a thing now.

“Uuu~ ♡I’m cumming- cyumming ooogh, oohh…!!♡” his tongue lolled out in pure bliss, his hips grinding back on Zhongli’s fingers as they rubbed his prostate through his orgasm. Small cock spurting little to no semen as he came down from his high. 

Those magical fingers retracted out of the hot cavern, giving Childe’s ass a wet slap to praise him. But that produced a whimper from him, already feeling horribly empty at the loss of being fucked. “N-no, Zhongli, it’s not enoughh… still- want to get filled ♡ m-more, please?” Childe rubbed his big tits on Zhongli’s strong chest, trying to find some small friction to get off.

He was interrupted when the consultant swept him off the floor and carried him to another room, Childe’s legs wrapping around the other man’s waist in surprise. He was effortlessly plopped onto a soft mattress, Zhongli laying down beside him right after. He gave a big sigh as he moved the younger one on top of him, “you never listen, do you, Childe?” 

Zhongli twisted the other till his ass was just above his face, while Childe’s was staring straight at a humongous bulge in his black slacks. “Although I doubt the need of more lubricant considering your hole is leaking profusely with plenty, I would still like to teach you how to put more work into pleasing me. Be a good boy, Childe.”

With Zhongli’s dick in his face, it’s pretty obvious what he’s demanding. Childe lowered his chest till his tits were resting softly on Zhongli’s stomach, his hands working at getting the fat bulge from its confines. Once Zhongli’s underwear had been pulled down, his giant cock had sprung out in all its well-over twelve inch glory. Childe’s eyes went wide, his mouth drooling at the thought of something so big going inside him, knocking on his womb till it was bursting with clumps of cum. He couldn’t believe Zhongli was keeping such a majestic tool in his pants all this time, Childe would’ve already been at the man’s feet had he known.

He didn’t stall any longer, mouth engulfing the tip with slobber as he licked and sucked. Childe lapped every thick vein lovingly, making sure to coat the entire length to get it wet. The harbinger seemed to love the taste of Zhongli’s precum as he suckled at the tip trying to get more out of the big cock.

“Mnnrgh~~ ♡ pahah, your dick tastes so good Xiansheng, it’s gonna make me addicted…♡ mmn- slurp~♡” he went back to deepthroating the consultant, only getting halfway before gagging as it hit the back of his throat. Childe happily moaned around the cock, eyes rolling back and tearing up from the action.

Zhongli followed the other by bringing Childe’s ass down till his mouth was sucking on the puffy rim, tongue diving deep into the prepared hole. He could feel the moan vibrating through his cock at his stimulating, sucking harder to coax more moans out of the younger. Childe bucked back in pleasure, nearly crushing Zhongli under his soft ass.

What was an expression of pleasure turned to shock as he felt Zhongli’s tongue explore deeper than a tongue should go. Lifting his lips off the cock with a pop, he looked back to see the consultant had a snake-like tongue. Guess Morax has tricks like that up his sleeve, huh.

That long appendage traveled deep and rubbed his walls affectionately, Childe couldn’t help his moans and the small buckle of his hips at the stimulation, his hole twitching in delight. Each press to his walls dripped more slick onto Zhongli’s face, the older lapping up all he could. He wasn't gonna lose to Zhongli though, he could easily make the consultant feel good too.

Childe shifted his body upward till he could pull out his breasts and line them up with Zhongli’s cock, trapping the length between his slippery tits. He rubbed his boobs all over, keeping the half he couldn't get in his throat warm while going back to sucking on the half he could. Zhongli gave a low growl that traveled through Childe’s walls, which in turn caused him to moan too. The neverending cycle of pleasure kept going as they worked on each other.

Childe was nearly hitting his point again, the scent of Zhongli’s heavy musk coming from his dick was intoxicating him. He could also feel Zhongli getting closer to the edge with how his cock was twitching and pulsing. And so Childe gave one last harsh suck to the tip, massaging the rest of the length with his milkers, each in one hand. As Zhongli came with a muffled shout, heavy cum flooded Childe’s mouth, overflowing from the corners of his lips as he drank it all up. 

The feeling of a thick load being poured into him, along with Zhongli’s filling tongue was enough to send him into orgasm again. That humongous cock still pumping cum down his throat kept him locked on it for a while, basking in the glory of being filled. 

Childe pulled off slowly, his face wrecked with fluids and his lips a pretty red. He looked back to see Zhongli panting from being nearly suffocated by a thick ass. Childe got up, moaning at that tongue slipping out of him. 

Turning to face Zhongli, he looked at him with more desire than before, sitting down till he flattened his cock between Childe’s behind and his stomach. 

“M-more!! ♡ Please Xiansheng?? I was good right? So spear me on your fat cock~~ I’ll be your little bitch- anything, just fuck my pussy till I’m stuffed~~♡♡ hhaah- aahnn♡ knock me up with your kid, if it’s you, I don’t mind ♡♡ anything for Xiansheng~”  

Childe was quickly flipped till his back hit the bed, his legs lifted till his knees reached his ears. The position spread his already gaping hole wide for all to see, dripping in copious amounts of slick and saliva. The puffy, twitching rim all red from being sucked, and velvety walls clenching around nothing. It looked perfect for a good fucking. 

Zhongli’s hands holding up each knee pushed Childe’s thighs closer, squishing his titties together for an erotic view. 

“Did you mean that, Childe? You would take my kid?” It was said in such a dangerous, rumbly tone, one that made Childe swoon at its power. 

“Yes…♡ breed me with your thick cum~~ uu~ ♡ oh! I wanna be pumped full with your babies~~ C-cock~♡ use me like your cocksleeeeve forever~♡haa~~”

“ I’m glad you feel that way, Childe. Then let's settle this with a little contract.” Zhongli lined up the fat head of his cock with the inviting rim of Childe’s anus.

He placed his palm over the heart womb tattoo before sheathing his length completely into the soft cavern. Both his hand and cock simultaneously hit Childe’s prostate from the inside and outside.

Childe’s eyes rolled back, his tongue hanging out in a silent scream as he came from the intensity of being filled all at once. His hole gushed out a waterfall of slick and his thick nipples squirted sweet milk all over his thighs. 

Zhongli looked down at the boy’s navel, examining the new symbol replacing the old womb tattoo. A combination of the classic geo marking along with the intricate heart patterns from the abyss. It looked truly beautiful on Childe’s milky skin.

“If I were to have released my semen in you, you would have slowly begun to return to your normal body by the next day. Except bearing a fetus in you of course. However, now with my marking on you, I’ve made the modifications on your body permanent, so you can safely bear my children for a very long time. In other words, you have become my mate.”

Childe still in bliss from his orgasm dumbly repeated the words, “ mate…? Mate♡ Xiansheng’s…” A small smile bloomed on his cheeks at Zhongli’s words.

“Yes, Childe. We’ll be mates,” Zhongli gave a kiss on the other’s forehead before setting a relentless pace into Childe’s hole. His hips slapping against soft ass with every thrust, filling the room with sounds of loud, wet smacking.

Every merciless hit to Childe’s sweet spot would make his legs fall open and wide, trying to get more cock in his slutty hole. Their rough copulating even had the bed shaking along with Childe’s big tits jiggling from the force. 

“Oh! Ooh..! ♡ ah- right there~ k-keep fucking me there♡ yes- YES!! Nnhaa~~ so good, so full!♡” Childe laid there submissively, letting the former archon fuck his insides all he wants. 

Zhongli leaned down till he caught a leaking nipple in his mouth and sucked at the tender bud for milk, his thrusting never stopping in fervor. 

“Hyaannh~~ ♡ uuuh~ yes, milk me more!! ♡ suck on my bitch nipples~ ah- oh! Make me your cockslut Xiansheng~♡ mm~” Childe came again from the stimulation. 

Zhongli kept alternating between swollen teats till the head of his cock hit another entrance deep in the younger’s opening. A broken squeal leaving Childe’s sloppy lips from having his womb violated. His small, useless cock spurting nothing by this point.

Zhongli aimed straight into the tight little opening, battering it till started to slowly loosen for his cock to fuck it. 

“Ahn! Ah! Hyuu~ ♡ ooh you’re abusing my womb! ♡ mm~ hn- cum inside! I want your fat load in my pussyyy~~~♡♡”

As his pace increased, Zhongli used more force to open up that tender muscle, till finally, the head pierced it with a triumphant fountain of cum. Zhongli’s semen filled up the little room in heavy spurts, the cockhead snuggly fitting at the entrance, filling Childe’s insides. 

“Nhaah- th-thank you Xiansheng!!♡ ah! Ooh…! So full, uuuhu~~ ♡ I love you- y-your cock~~♡♡” Childe mumbled happily at finally getting knocked up. 

Once Zhongli’s load had ended, he pulled out harshly, earning a gasp and pained whine from his mate. As he soothed him by rubbing his thighs, the cum that coated deep in Childe’s insides started leaking out of his gaping hole from the sheer amount. Well that’s not good, Zhongli thought. 

The consultant hauled up the other till he was plopped on his lap. Childe with little energy left slumped onto Zhonglis chest, groaning from the cum trickling out of his anus. 

“Zhongli~~ do something~, hnnm put your cock back in me,” Childe pawed at him, sounding like he was about to cry from the loss of dick.

Zhongli grabbed the harbinger by his ass, lifting him from atop his legs till his leaking hole was above the tip of his cock, before letting go and watching as the greedy entrance engulfed the twelve inch meat completely, butt slapping on balls.

The head pierced straight through Childe’s full womb till his stomach had a little, vulgar bulge sticking out. Defined veins on Zhongli’s cock rubbing against his sensitive walls on the way in. The former archon watched in awe at Childe’s blissed out expression, the boy giving a wobbly smile at being filled to the brim again, cumming just from being penetrated.

Zhongli didn’t give him any time to rest, immediately fucking his cute womb and listening to the happy moans his mate choked out. His cock tip abusing the little cavern till it was beyond tender and soft, training it to be ready to fuck into anytime.

Each bounce of his ass on Zhongli’s cock made those milkers jiggle so distractingly along with them, so Zhongli just shoved his face deep between the soft tits. 

“Hah- ah! ♡ d-deep~ hitting me so good~~♡ right theree~ oh! Ooh! Knock me up again Zhongli~~♡♡ uu~” every punch to his sensitive pouch messed Childe’s face up even more. His mouth became a slobbery mess, tears and snot making him look wrecked.

“I’m guh -gonna cum again- hah , take it well, my bitch,” Zhongli’s words came out deep from the other’s chest. His pace picked up, making sure his potent semen stays inside the little cavern this time.

Zhongli grit his teeth as his load shooted a massive amount, painting Childe’s womb in a glowing white. His thick cock plugging the other’s puffy, red rim as a cute bump started to balloon on Childe’s stomach from all the cum.

Childe also came hard, mumbling thank you♡s and praising Zhongli’s dick like he worshipped it. His walls clench on it, not wanting to be empty.

They stayed there for a while, Childe’s hole, warming the man’s cock as Zhongli went back to sucking on his teats. The two basked in their afterglow, only to wait until they could go for another round.

——————————

After that night, they continued living like normal for the most part. It took nearly a week for Childe to come back to the Northland Bank, except his body didn’t change back. 

Walking around the harbor with heavy badonkers was too embarrassing for the harbinger. He didn’t really mind them, but the stares from perverted men looking at him like they could see under his clothes was just not it. Luckily, his subordinates never questioned his new pair of tits, or why he was absent for a week. Just some blushes here and there.

They also never questioned the geo tattoo on his navel, or the small bump underneath it. 

On most days after work, Zhongli would come pick him up so they could go out for dinner, wrapping his arm around Childe’s small waist. And after dinner… 

The former archon would breed him all over again
