[GI] Kinktober Day 21: "Breeding Kink"

Summary: The life of a harbinger was chaotic and the threat of death, though low, it wasn't completely impossible. Henceforth, Tartaglia decides that it's best to ensure that his legacy continues.

Warning(s): Established Relationship, Breeding kink (obv), Squirting, Some mentions of death (not too much though), Tartaglia being whipped for his wifey,

Side Note(s): If it isn't clear atp, I have a litttttleee bit of a crush on Tartaglia <333. [Also this is one of my lil' late fics since I was hit with the writer's block virus]

"C'mon baby...think about it, how good you'd look swollen with my kids~" Tartaglia whispered in your ears as he was currently balls-deep inside your weeping pussy.

The lewd sound of squelching echoed throughout the room as Tartaglia bullied his cock into you, your hands fruitlessly grabbing and pulling at the sheets beneath you as he cooed into your ear, begging for you to take his cock. Since his latest mission in Fontaine, where he fought against the All-Devouring Narwhal. You had spent the last few weeks practically babying him, not a single soul aside from another harbinger was allowed to see him.

You had patched up countless wounds, and endured too many nights where he had a dangerous fever.

You worried your husband would be taken away from you before you'd even reach your fifth year with him! Tartaglia, although he tried to hide it with confidence and jests, shared your concern and tried to make you feel as comfortable and confident in him as he possibly could. Yet...the only way he could truly make you feel alright, in his mind...was by giving you a baby.

"H-Honey...!" You keened as you began to rock your hips back onto your husband. "W-What's gotten into you?" You moaned, struggling to look back at your ginger lover.

Almost as if he were trying to suddenly hide away, Tartaglia buried his face into the crook of your neck, breathing in your scent as he groaned at the feeling of you clenching around him. "J-Just tryin' to give you a baby..." He whined. "S-So that you'll have someone to baby over, w-while I'm gone." He continued to stutter out, his cock twitching inside of you as he started to rub his hands up and down your body, as if he were struggling to figure out where he wanted to keep them until he finally settled.

One hand fondling your breast while the other tended to your neglected clit. The sudden pleasure made you scream in pleasure, the already tight knot in the pit of your stomach growing tighter as you felt your husband somehow fuck into your slicked cunt even faster. "Gonna give you a couple of kids Y/N..." He babbled as if he were drunk off the feeling of your pussy. "Then you won't have to worry, a part of me will still be around~"

"I-I'd still miss you..." You managed to force out as you just managed to look behind you to see your husband panting over you, his sapphire blues wet with pleasure and hidden emotion, you just couldn't pinpoint right at this moment.

Perhaps later, of course. "Don't—Ahh...—wanna have babies alone." Tartaglia pressed himself closer to your backside at your words, whines falling from his lips more and more as he continued to feel his cock twitch the more he felt his orgasm creep closer up onto him. The more he felt your pussy clench and unclench around him as he practically felt himself growing more and more addicted to the feeling of your walls by the moment. "You won't have to..." He moaned in your ear.

He knew he couldn't die from any future missions of his, children aside. The idea of leaving your cunt alone to not be filled by him, stuffed and tended to...it annoyed him more than anything!

"C-Close...!" You moaned, Tartaglia's fingers circling around your clit faster and faster. The harbinger nearly choked on his breath with how impossibly tight you became all of a sudden as if you were trying to wring every drop of cum from his balls. "D-Don't stop—"

"I don't plan to." He smirked behind you before he moved his hand to press it against your back, forcing you into a mean arch and fucking even harder into your cunt, his eyes glued to the way your cunt gripped onto him and how your slick stuck onto his abdomen.

Until...he saw you squirt.

"Fuckkkk..." He groaned. "How come you haven't done this sooner?" He licked his lips as he fucked you through your orgasm, the tiny aht aht ahts that left your lips making him want to fuck you even harder than he already was. But, as you began to whine from overstimulation, he realized he'd have to save that for another time. The last thing he'd want to do is break you completely, there was plenty of time for that down the line.

Tartaglia began to grind into your cunt, leaning back over you as he felt his front press back onto your back. "I'm never leaving you Y/N..." He whispered. "Death won't take me away from you...I-I promise." He managed to get out before you moaned softly as the feeling of his warm cum pooling your insides, some escaping and dribbling down the back of your thighs much to the harbinger's dismay.

He pouted. "Why'd you waste my cum?" He grumbled, lightly biting on your ear.

You looked back through hooded eyes before a dopey smile crawled onto your face. "...T-Then fill me again..." You begged.

Oh, he definitely couldn't die too soon.

I had to get them out of my system . . . . . . 🪙🧪

[rnaxxy]

[nerdinqq]

i saw a bat themed hoodie on my feed and wanted to put it on Ororon cuz why not🦇

[a-998h]

Hey! It’s 🍉ANON! Hope y’all missed me!

Anyways, I was wondering if I could request again! Of course, if I’ve already requested something, don’t mind this one! Just put it to the side..Or whatever

I would like to request a Yandere!SAGAU + Teen!Reader

Basically, since it’s a (Platonic) Yandere, I think they would basically all coddle {Reader}

Like since they’re a God and all, they’re dressed in fancy attire- but the clothes are always to big on them or they’re made in soft colors, so the characters coo over how ‘tiny’ and ‘cute’ {Reader} is

And if any of them are designers, they make them cut outfits like poofy dresses or little suits and force them to wear it

Like {Reader} is like, “I’m a teen! And a GOD! I refuse to wear this!” But they still end up wearing it lol

And maybe the characters fighting for their attention and time, maybe becoming a little too aggressive towards each other.. Maybe even threatening others to stay away from {Reader}..

Or! Or, if they talk about their family before they were transported, the characters engrave that into their brains basically and try to act like their them, or get upset that they mention that and say how they’re their ‘new family’

Anyways, I’ll make this short so I’ll end it here! Also, you as a writer truly inspire me every time you take my requests! Maybe one day I’ll be brave enough to post my ideas on my own online.. Thank you!

Sincerely, 🍉ANON

🍉ANON Thank you for the compliment, and I'm looking forward to the day you grce Tumblr with your writing!

Yes, Reader is coddled to high heaven. The archons have had unoffical custody court over you. With some math done by Neuvillette, each archon/ region gets equal time with you. You're a young human and young god, so everyone thinks you need protection from everything. There are different types of coddling that you experience, all based on the type of platonic yandere the character is.

______________________________________________________________

Mom Types: these platonic yanderes will now act like your new mom. They are strict, caring, and will make sure you become well rounded if it's the last thing they do. While there is variety in the parenting styles among these yanderes, there is still a common thread between them.

(Jean, Eula, Xianyun, Ningguang, Raiden Ei, Kujo Sara, Kokomi, Faruzan, Dehya, Arlecchino, Clorinde, Chiori, Chevreuse)

______________________________________________________________

Dad types: These types will be the best dad they can. They're protective over you, ready, willing, and able to fight anyone for you. They pull double duty as best friend, and guardian. They're strict when you need to be, but sometimes you can flutter your eyelashes to make them bend to your will. Agian, there are different parenting styles between each yandere.

(Neuvillette, Wriothesley, Alhathiam, Gorou, Kazuha, Baizhu, Zhongli, Albedo, Diluc)

______________________________________________________________

Uncle Types: These are the characters who are too irresponsible to be dads. They are the ones that help you cause small scale mayhem, while also making sure you have fun. They'll teach you street smart things, and are more lenient platonic yanderes

(Kaeya, Venti, Itto, Heizou, Cyno, Tighnari, Kaveh)

______________________________________________________________

Aunt Types: These are the characters who are the gender bend version of the uncle types, with a more caring side.

(Navia, Emile, Candace, Nilou, Nahida, Shinobu, Yae Miko, Beidou, Yelan, Shenhe, Yanfei, Ganyu, Keqing, Mona, Lisa, Rosaira)

______________________________________________________________

Cousin Types: These are the characters who are cousin like in the way you two interact. There is not a sibling bond, but there is a ride or die bond. This platonic yandere will keep you out of trouble for a price, while helping cause problems.

(Amber, Noelle, Fiscal, Mika, Xiangling, Xinyan, Hu Tao, Yun Jin, Sayu, Kirara, Dori, Wanderer, Layla, Charlotte)

______________________________________________________________

Big Brother Types: These platonic yanderes are your big brothers now, no, there is no arguing with them about this. They well care for you, being soft and kind is their thing. But, they will keep a tight leash on you if you even thing of doing anything dumb or they see a threat to you.

(Lyney, Fremient, Sethos, Ayato, Thoma, Gaming, Xiao, Xingqiu, Chongyun, Childe, Razor, Bennett)

______________________________________________________________

Sibling Types: These platonic yanderes are like the big brother yanderes. Kind, soft, and willing to protect your and your innocence. When it comes to spending time with them, there is mire dress up than you'd probably like.

(Klee, Diana, Barbara, Qiqi, Yaoyao, Ayaka, Yoimiya, Collei, Lynette, Furina, Sigewinne)

______________________________________________________________

The mom and dad types dress you in fancy clothes, finding it cute how big they are on you. Whenever you try and argue about wearing the fancy clothes, the mom and dad types use their authority voices, the aunt and uncle types use bribery, and the sibling and cousin types uses a mix of puppy dog eyes and bribery.

They is a lot of rivalry. Different sets of sibling are at each other's throats, the cousin and sibling types are usually at odds. Some mom and dad types bicker while the aunt and uncle types compete with each other and the mom and dad types. It's a mess you're always caught up in, and it's is never fun.

If you mention anything good about your family back home, the respective type of platonic yandere will try and copy that behavior. If you mention anything bad, they'll avoid that behavior like the plague

[GI] Kinktober Day 10: "Exhibitionism"

Summary: After your stunt with Tartaglia, you are forced to deal with the repercussions of Capitano's not-so-well-hidden jealousy.

Warning(s): Reader is fucked in front of an audience, Dub-Con, Degradation, (Probably a whole slew of other warnings that I can’t think of rn).

Side Note(s): Okay so—I switched it up last minute to exhibitionism because I realized that I get confused easily between that and voyeurism (+ I have more of a love for exhibitionism anyway).

Also, this is kinda an unofficial pt. 2 to the "Sharing" fic I posted? I mostly kept to the same "storyline"(?) because it was easier on the brain for me.

Your relationship with Capitano has been in a...weird spot, to the least, ever since that day between yourself, Tartaglia, and Capitano.

At the end of it all, the men didn't even get what they had originally wanted. You were far too fucked-dumb to even decipher who was who, much less come up with enough letters capable of yelling out a name. But, for the sake of being tired himself, Tartaglia had admitted "defeat" and carried on his merry way! Eventually, he left Capitano's war band and continued on his own personal mission, leaving you behind and working for Capitano permanently like you were originally supposed to.

But it's been awkward.

Capitano was curt with you, only speaking to you when he needed to. If you were caught taking a moment to relax, you began to pray that Capitano wouldn't happen upon you, he'd only immediately order you to get back to work!

No longer did he greet you warmly and no longer did he seem to care about your well-being. When the entire war party moved, he no longer expected you to be by his side, nor did he constantly check to see if you were! You could've been at the very back of the party and he wouldn't have given a single damn.

You had a mind to call your boss out on his behavior, pull him aside, and ask what the issue was and...whether or not there was still something between you both.

Although, you already had a mind to think that any feelings that may have started to blossom had long since been crushed underneath heel and foot.

Until today that is, when you were in your tent and finishing up some reports.

. . .

You quickly rose to your feet when Capitano suddenly entered your tent, bowing your head as you murmured a respectful 'Lord Capitano' in greeting.

He responded with a gruff noise of acknowledgment. "There will be a feast held tonight," Capitano said.

Your brow cocked, a feast? You hadn't heard anything relating to a feast at all. "Our efforts and missions have been going smoothly, I figured it's overdue to reward everyone in this camp. Even you." You bit the inside of your cheek at the cold way he addressed you. Had you known that accepting Tartaglia's offer—that rogue ginger-headed charmer—would lead to such an awkward tension between you and Capitano, you would've never allowed Tartaglia to trick you!

"...That's...that's kind of you." You said before sighing.

He nodded his head before turning to leave, prompting you to quickly stop him. "M-My Lord," You started off. "About that day...are you still—"

"I'll be taking my leave,"

"Lord Capitano!" You said more firmly this time, walking around your desk and beginning to close the distance between the two of you. "You can't continue to avoid me, n-not to mention treat me as I—" You stopped in your tracks when the first harbinger turned his head to look at you. And although you couldn't see his eyes, nor his expression behind that dark mask...the danger that oozed off of him. It made you audibly gulp as you took a few steps back.

You bowed your head in silent apology. "...You will come to my tent before the feast officially begins." Then, he walked out. A cold bead of sweat dripped down your neck at the vague order. Either it would be nothing aside from more work, Capitano deciding to kill you, or...hopefully, he'd finally get over his attitude and talk to you.

You couldn't stand how things were at the moment.

So, when the time finally arrived and the feast was ten minutes away from the beginning. You found yourself in Capitano's tent, your hands resting neatly in front of you as you stood at the entrance of his lavish tent. "My Lord, the feast will begin soon." You gently reminded him. "Shall I alert the soldiers of anything before it begins?" You continued.

You didn't receive a response until Capitano emerged from the covered part of his tent, adorned in the usual attire he wore when he appeared during important Fatui functions or battles. "No," He answered. "Simply follow me." Your brow rose as he walked past you, but nonetheless, you dutifully followed after him outside and back into the steadily warming air thanks to the bonfire that had just been set up.

As the soldiers began to gather, however, Capitano clearing his throat before he broke out into an, admittedly, very admirable speech as he thanked and showed gratitude towards his soldiers. Certain things started to stand out to you as your eyes washed over the crowd. Such as...the doctors and nurses of the camp weren't present, surely they deserved some praise and appreciation too? Too many times have soldiers or even your boss himself had come into the camp injured from head to toe! They'd quickly patch them up and almost seem to perform magic, you've heard soldiers state that one doctor in particular was good at numbing the pain!

There were none of the cooks, blacksmiths or even the younger soldiers that were fresh into the party, tasked to simply stand aside and watch.

All this boiled down to this "feast" being composed of nothing more than the more experienced soldiers, simply leaving you with a number ranging around the hundreds.

As pieces started to merge together although...a heavy hand placed itself on your shoulder, and then, you tuned back into the conversation. "...You will all bear witness as to my secretary learning who she truly belongs to, hopefully with an audience, she will learn not to be so easy for others."

What had just happened?

. . .

"Apologize." Capitano gruffly ordered you as the loud sound of your squelching cunt echoed through the camp. Not even the whistling winds could muffle your desperate panting as Capitano fingered your soaked cunt, taking special care to not knick you with his claws. "Apologize for being such a desperate whore..." He hissed out, loud enough for everyone to hear. "...for being so easy to fuck, not even having the courtesy to quiet yourself down despite being in a camp full of my soldiers."

Your cheeks burned with shame as you could feel hundreds of eyes on you. You didn't know whether you wanted the soldiers to be disgusted at the sight and turn away or if...you preferred this in a sick way, although there were some women amongst the crowd, the heavy sound of panting amongst the men made you clench around nothing, your slick beginning to drip and run down from your cunt and onto Capitano's lap.

Something that the ever-vigilant Captain didn't miss.

"You shameless whore." He snarled in your ear, your body shuddering at the feeling of his sharp teeth grazing the skin on your ear. "You're getting even wetter at being watched?" The harbinger nearly had a mind to laugh at how your legs twitched, as if you wanted to curl into yourself at his cruel words. He almost allowed himself to feel bad, until he smelled how your arousal grew at his words.

Oh...so you liked this.

Well...that explained everything.

Slowly, he took his fingers away from your cunt, a string of arousal still connecting him to you as he brought them up to his face. "So that's why you fucked my fellow harbinger." He sneered, opening and closing his index and middle finger, playing with your slick.

"H-Huh?" You moaned, both in disappointment and confusion. Despite the cold, your body burned with desire, one that grew more potent by the passing second as you felt Capitano's obvious hard-on behind you. You were grateful for your tears blurring your vision, for as Capitano continued to let you sit in his lap exposed to his soldiers, you at least could fool yourself into thinking that no one was paying attention.

But only for so long.

A scream tore from you as the Captain's fingers returned to your sex, his fingers dipping into your pussy before they had quickly found your g-spot whilst his other hand wrapped around your torso to begin flicking rapidly at your clit. All the air in your lungs were nearly knocked out of you at the rate of how quickly you were approaching your climax, your hands fruitlessly clawing at Capitano's forearms as drool started to dribble from the side of your mouth, your eyes starting to roll into the back of your skull.

"C-Captain..." You moaned. "O-Oh Archons...!" You keened.

He didn't relent. "Take it," He ordered as if he were ordering a soldier. "Considering you've taken me and Tartaglia at the same time...you should be used to the pleasure." He chuckled gruffly.

He tightened his hold on you as you squirmed. "Slut," He spat. "Quit squirming."

It was only when Capitano suddenly bit down on your shoulder were you pushed off the edge, your mouth falling open in a silent scream as your body stilled and your vision turned completely white. For a long while, you drifted on that cloud of sheer bliss...until you were brought back down by the feeling of something hard slapping against your cunt, snapping you back to reality before you were face to face with the harbinger's cock.

Starting off at a lighter color at the base before turning into a dark purple towards the middle and upwards at the tip. You shuddered when you remembered that Capitano's cock was inside of you...not even a whole two weeks prior! The ridges along his dick were intimidating, especially with the way it twitched and oozed pre-cum.

You gasped when he parted your cunt wider with his fingers. "If you won't apologize with your mouth..." He started off before he lifted you a little, as easily as he would carry a sack of flour before the tip of his cock pressed against your opening. "...Maybe you'll be more apologetic with your pussy."

. . .

Capitano didn't waste any time to wrap a hand around your mouth, although, the sheer size of his hand nearly engulfed your entire face. As he pressed you impossibly closer to him, he made sure to get really close to your ear as he spoke to you. "Make sure to look my soldiers in the eye as you apologize to me with this cunt of yours." He said before he slowly pushed himself into you.

Immediately, you broke his command, your eyes threatening to roll into the back of your head. Something that Capitano quickly corrected with his free hand slapping the side of your thigh. "Look at them." He reminded you. As more of his dick sunk into you, your eyes blurry and struggling to focus as you looked at the soldiers before you. You accidentally made eye contact with one of them, all before...your eyes glimpsed at his noticeably hard cock.

In fact, you noticed how all of them were hard.

Your cunt clenched tighter around your boss' dick at that realization. "Fuck—" He whispered. "You must've noticed, hm? How they all yearn to fuck you? My secretary." He continued.

When your pussy twitched at his words, he lightly pinched your side in punishment. "Greedy pussy...still eager to take more cock despite having me inside of you?" A muffled yelp resounded against the harbinger's hand when the rest of the Captain's dick was suddenly pushed into you. More moans followed suit as his fat tip began to poke and prod at your sweet spot, deep inside of you. "Don't worry, I'll curb your greediness soon." He whispered, the sheer possessiveness in his deep voice making goosebumps pop up all over your skin and down your spine.

More than you cared to realize, you loved when your boss was possessive over you. And that love only grew more when he started to move, his balls slapping against your skin as he took up a brutal pace almost immediately. You tried your best to keep your moans quiet when he suddenly released his grip over your mouth for it to take up stationing itself on your waist, aiding in pulling you down faster and harder against his pelvis. But it was so fucking hard to be quiet when he was fucking you like he was afraid of loosing you. As if you'd be gone the second this was all done.

"C-Captain..." You groaned. "F-Feels so good...!" You continued to cry out, blissful tears running down your face as you lost yourself in the feeling of his cock. Delicious sparks ran up and down your spine at the feeling of the ridges alongside his cock rubbing against your walls, your arms coming to loop themselves around the back of the Captain's neck as his groans started to become more and more audible.

His cock was touching all the right spots inside of you, making you see stars behind your eyes. "Fuck—" He snarled. "Archons...your cunt is squeezing me so tightly." He groaned, his head coming to bury itself in the crook of your head before he whispered more words you were too cock-drunk to decipher. You whined when he sped up the pace of his thrusts against you, your cock-drunk babbles turning from moaning to pleading for him to go easier on you, much to the harbinger's amusement. "Too much?" He mocked, faking sympathy as he fucked you harder in turn. "That's too bad. You wanted this, so you're going to fucking take it." He growled.

He was suffocating you in the best way possible as each time his cock slid into you, it practically punched the air from your lungs, the scent of sex in the air making it feel like it was hard to breathe. But you loved it. You assume that's why your second orgasm snuck upon you so suddenly, the presence of people watching your boss fuck you silly on his lap...the degrading words he whispered into your ear in combination to the pleasure. It was all making your mind spin. "You're fucking tightening up on me..." Capitano grit his teeth together, his claws beginning to dig into your skin.

"Gonna cum?" He asked before he kissed the side of your neck, lightly nipping it as he felt his orgasm begin to approach as well. "Cum all over my cock then." He cooed, the feeling of his twitching dick battering against your cervix making you let out a few more strangled moans before you froze again him with a loud cry.

"Fuck...fuckfuckfuckfuck." He groaned, fucking you through your orgasm for a few more thrusts until he stilled against your still twitching pussy with a loud hiss of his own. You moaned softly as you struggled to come down from being dicked down, a dopey grin plastering itself onto your face as you looked behind you with both a happy expression and a shy one.

The harbinger, although dazed and hidden behind his mask, smirked confidently, the way he moved to run his fingers through your hair shockingly gentle.

He doubted you would want to go and find someone else to fuck after tonight.

I’m bored thought about this at 4am had to write it down before I just forget about it completely

Genshin Men | What Makes Them Flustered

{diluc, xiao, gorou, kaeya, zhongli x fem!reader}

++============++

Diluc

It’s a bit odd but when the two of you often take walks together, Diluc’s strides are longer than yours and you’re always slightly behind him. When that happens you grab onto the his sleeves of his coat he wore gently getting his attention. It would make him look back at you walking to his side. It made him a bit flustered bc it was cute yet he’d never admit to you.

Xiao

Xiao was never a touchy guy that was until he met you but he kept it behind closed doors. You were more of the touchy, affectionate one. He thought he was used to you touching him yet he wasn’t bc one day something made him flustered. Standing out on the balcony you walked up behind and touched his bare back and greeted him. It made him shiver as his face turned red as he swatted away your hand and disappeared. It left you dumbfounded.

Gorou

Since the two of you got together he’s given you permission to touch his tail but his ears were a different story. I find that his ears are more sensitive than his tail. You played with fire one day when you wondered why you couldn’t touch them. He flushed red when you reached up to touch his ears when you both alone together and you think you heard a whimper come from him then Gorou tried to swat your hands away while barking at you to stop.

Kaeya

Not many things can make this man flustered, trust me, you’ve tried but, not everything. When you hugged him from behind it really caught him off guard mostly because you squeezed his waist and felt him up (bc you realized how small his waist was. Big cake, tiny waist kaeya is canon lol 😩). He gasped at your sudden action and his face flushed red. His gaze was set on you and it look like it was a warning. Say goodbye to your ability to walk.

Zhongli

The ex-archon is never the one to be flustered but, you knew he could fluster you even if he doesn’t intend to. Zhongli has found that he likes being close to you even when the two of you were just friends. Getting closer meant more than just talking and hand-holding. He was working at the Funeral Parlor and he had you there for company when you noticed his tie was a bit loose and crooked. You walked over to adjust it, his eyes widened as he looked up at you and you looked at him, smiling at him until he looked off to the side with light blush on his face.

[a-998h]

Hey! 🍉-Anon here! I’ll just make a quick SAGAU request!

If (Reader)’s culture resembled one of the Seven Nations? How would everyone react? Like I would think that the people and characters would constantly be boasting about it, and always showing off

And it would be worse if (Reader) showed favoritism to that one Nation, or characters that come from there or dress/act/etc similar to their culture

I think (Reader) would constantly ramble on about their culture, and days later the whole place is decorated in items remade by the characters to resemble their culture and make (Reader) more comfortable

And (Reader) always visits that Nation, and the always spends time with the Archons and other characters

That’s all I’ll write, so have a good day!

- 🍉ANON

Thanks for the request 🍉 ANON, I love hearing from you!

so, for those new to Genshin or haven't been in the fandom for a long time there is some important context about the nation's that I need to share.

Mondstadt is based on Germany

Liyue is based on ancient China

Inazuma is based on ancient Japan

Sumeru is a mix of ancient Egypt, India, Persia, and Mesopotamia

Fontaine is based on France

Natlan is is a mix of Pre-Columbian Latin America, Sub-Saharan Africa, and Oceania

Snezhnaya is theorized to be based on Russia.

The historians of Teyvat always debated over which nation/element came first. So, you having a culture similar to any of the seven nations would settle that debate. But then there wod be debate as to why that particular element was created first, so your culture closes one door and kicks another one down. You will be asked questions by said nosy scholars and historians, because merds will get answers even if it kills them.

The characters if that region would feel great pride in knowing that their nation and its element was supposedly the first to be made by you. The archons would handle the news with great maturity, and I'm kidding. The archon of that region you share a culture with would kind of brag about to the others in however way they see fit.

In order from most to least mature we have, Tsarita, Raiden, Nahida, Zhongli, Mavuika, Furina, and Venti.

Now, as humans in both Genshin and reality, we are more drawn to people we have a connection with. You favoring characters from. The region that shares a culture with you would be something you do unconsciously, not even seeing it as favoritism, but instead as connecting with those culturaly similar to yourself.

When it come the shrines, the one in what they consider your "home" nation, who be decorated upto the nines with traditional furniture, rugs, etc. In the other shrines, there would still be the culture of which ever nation it's in, but also some elements of decoration from the nation they assume is your "home".

Your rambles about your culture back home is what the nerds like to hear. Everyone sees your real life culture as an ancient culture that was the founding blocks for the nation that closely resembles it. The characters will let you ramble on, some take notes, some ask questions, and some don't understand but listen along anyway because they know it makes you feel better.

Your hang out days in your "home" nation is a real treat for the characters as you and them can bond over clothing, custooms, food, etc. The characters outside your culture will be more than happy to listen and follow you as you drag them around the city to show them your culture.

Overall, it makes Reader a little less homesick, gives characters more understanding on how to make you happy, and gives at least on archon bragging rights.
