Work Text:
It was really just supposed to be a simple request of studying together when they arrived at Zhongli’s house after class. There were a few concepts in math Venti didn’t get no matter how hard he tried to keep up with the class, but what’s there to fret about when you’re dating the top model student, right?
Placing his shoes neatly next to Zhongli’s, he can’t help but think about the size difference that’s so painfully stark between them. Upon entering the living room, Venti hears the lively sounds of Zhongli’s younger siblings arguing for their turn on the new gaming console.
“Back off, er ge!! Mom said it was my turn!” Yanfei yells angrily, grubby hands prying the controller away from Xiao.
“Shut up, stupid!! Xiao yells back, removing a hand to block Yanfei from getting closer to him.
Relentless, Yanfei puts her entire weight on him until they’re both rolling on the ground, the controller long knocked out of Xiao’s grip. As they’re fighting, which looks like aggressive hugging, Zhongli and Venti both enter into view. Not noticing their presence, the both of them continue to pull on each other’s hair and squishing each other’s cheeks.
Looking at the scene before them, Venti couldn’t help but laugh while Zhongli clears his throat to signal his rowdy bunch of siblings he’s home with company. Sure enough, the both of them stop and scramble to make themselves presentable. Yanfei runs over to Zhongli, both of her chubby arms wrapping around one of Zhongli’s legs as she complains about her second older brother to her oldest.
“Zhongli gege! Xiao gege’s being a meanie and he called me stupid just now!” she wails, burying her face into his right leg. Zhongli pats her head with a gentle hand and looks over at Xiao.
“Where’s Ganyu?” he asks, now attempting to carry Yanfei.
“Jiejie is napping.” Xiao mumbles, looking down onto the ground. Seemingly jealous over how Yanfei gets to be coddled by his older brother. Slightly pitying him, Venti walks over to the brooding kid to fluff his hair.
“Hey there, kiddo! Been a while since I saw you!” Venti smiles. Still, Xiao sulks, head still hanging low. Venti tries cheering him up with his secret card. “And look at you, did you grow taller?” Now, Xiao looks up at him with a beaming smile.
“Really?” he says happily, no longer the deflated balloon he was earlier.
“Yeah, let’s find somewhere to record your growth!”
“Okay! I wanna be as tall as da ge!”
Venti looks over at Zhongli, who’s now on the sofa with Yanfei in his arms as Yanfei is telling him all about the game she’s playing, something about pigeons and laws. He’s been overhearing what Venti’s been up to with his younger brother, so he gives his boyfriend a thumbs up to tell him thanks for handling him. They find the height chart next to the bathroom and Xiao runs up to the chart enthusiastically. Chuckling fondly, Venti squats down to Xiao’s maximum height and marks it on the chart. It reads 128cm.
“Well? Did you think you’re taller?”
“I think so!” Xiao beams, a big smile plastered across his face. Venti pats him on his head again, then he places his hands on Xiao’s little shoulders.
“Xiao, I don't think what you did to Yanfei just now was right, but not to say everything is your fault alright? So shall we go back and apologise to her later?”
The smile drops from Xiao’s face, a pout replacing it.
“But why! She’s always gets whatever she wants. It’s not fair…” he trails off.
“Xiao.” Venti says, his tone soft. He doesn’t want to agitate the younger. “What does being an older brother mean to you?”
“I don’t know…”
“Well, to me, it’s to protect and love your younger siblings! Sure the younger child may get coddled more than the older children, but it’s because they’re young, you know! My older brother used to get into a lot of trouble because of the things I’ve done, but still, he’s never treated me badly or said he hates me for that.”
Xiao stares at Venti, his little head deep in thought.
“You’re a big boy now right, Xiao?” Venti asks, smiling.
“Mm.”
“So let’s go apologise to Yanfei, alright?”
“Okay!”
They walk back over to the living room, where Zhongli and Yanfei are still seated. Xiao walks over and sits next to Yanfei. Yanfei stiffens, and as Zhongli stands up to leave the sofa, Yanfei extends one of her hands to grab onto his pants. Looking down at his baby sister, Zhongli pats her head to reassure her.
“I’m going to go study with Venti now, I trust you two will be on your best behaviour?”
They both nod their little heads and Zhongli walks over to Venti to lead him to his room. Walking up the stairs that’s situated behind the living room, Venti catches sight of Xiao trying to start a conversation with Yanfei. He stops walking, straining his ear to try and listen to their conversation.
“Feifei… gege is sorry he wouldn’t share just now.”
“Umm, I’m sorry too, shouldn’t hit you just now.”
“That kinda hurt you know”
“I said sorry! And you didn’t say sorry for calling me stupid!”
“Umm, sorry for calling you stupid too Feifei.”
“Hehe! Zhongli gege was right! Xiao gege is really nice.”
“W-what… da ge said that?”
His eavesdropping’s cut short when Zhongli tugs on his sleeve to gesture to him to keep moving. Once in the bedroom, Venti plops onto Zhongli’s bed and exhales a tired sigh.
“I’m so tired…” He complains, “Bring us some snacks, will you?”
Zhongli grumbles, taking off his blazer and hanging it on the back of his door, then rolling the sleeves of his dress shirt. Venti tries not to ogle at his forearms, focusing his stare at the ceiling. He hears the door close with a soft click and closes his eyes to rest them.
When Zhongli returns to his room, Venti is already fast asleep, both hands tucked under a pillow. Setting the snacks he got down on his table, he walks over to the sleeping figure, Zhongli attempts to wake Venti by shaking him.
“Hey, Venti, wake up.” he calls, shaking the lithe body. It does little to stirr Venti from his deep slumber. He’s usually a deep sleeper, so any disturbances or loud noises would do little to wake him.
Zhongli crouches next to his bed, admiring Venti’s face. He pokes on the chubby cheeks Venti has, silently appreciating his boyfriend’s cuteness. Trailing down to Venti’s lips, he smooths his finger across the smooth surface, heat slowly creeping up his cheeks. Without thinking much, he inserts two fingers into Venti’s mouth, rolling them around the other’s tongue. With the smaller still fast asleep, Zhongli pulls his fingers out, satisfied with how slick they’ve become. There was a faint blush dusted across Venti’s cheeks, looking at the vulnerability of Venti, the desire to fuck his boyfriend while the other was still asleep only grew for Zhongli.
Unbuckling his belt, Zhongli fishes his cock out of its confines, and positions it above Venti’s mouth. He fists himself quickly, allowing an orgasm to rip through him. With how much he’s been holding back from the approaching final’s week, it’s not surprising an orgasm came through rather quickly. His seed splutters over his sheets, pillows and most importantly, Venti’s face. Panting, Zhongli reaches over to smear his cum all over Venti’s lips, and kisses them, tasting himself on his tongue.
Zhongli mumbles a quick apology before he pries Venti’s mouth open to push his cock in. With the sudden intrusion of a humongous cock invading his mouth, Venti’s eyes fluttered open. Upon seeing his boyfriend kneeling between his head and a heavy weight in his mouth, Venti finally snaps his eyes wide open. Glaring angrily at Zhongli, he attempts to speak, but he could only hear himself muffled while his dick of a boyfriend proceeds to fuck his throat.
“Cock got your tongue?” Zhongli laughs, as he slams Venti’s head further down his cock. It hits the back of his throat and Venti chokes, earning a groan from Zhongli. He tastes the salty tang and feels lightheaded with the rough treatment Zhongli is giving him. He relaxes himself, letting Zhongli use him as he pleases, ignoring the ache in his jaw. An involuntary moan escapes him when Zhongli grabs a fistful of his hair and pulls himself off his cock, its tip red and slick with pre-cum and spit.
“Good morning, darling.” Zhongli says, ignoring the glare on Venti’s face as he pins him onto the bed with both of his arms on top of his head with a hand while his free hand works on pushing Venti’s uniform up to his armpits, exposing his perky nipples.
“What do you mean good m-”
Venti doesn’t get further than that, because Zhongli is already sucking on one of his nipples while he uses his free hand to thumb on the neglected nipple. The flush on Venti’s face heightens, his anger dissolving as he throws his head back onto the pillows and lets out a loud moan. He whines when Zhongli’s mouth and hand leaves his hardening bud.
Zhongli smirks as he places a finger in front of his mouth, signalling Venti to be quiet.
“Feifei and Ah Xiao are still downstairs you know. Also, Ah Yu is sleeping next to my bedroom.”
Venti’s eyes widen as he struggles to free his arms from Zhongli’s stupidly tight grip as Zhongli goes back to abusing his nipples. Zhongli licks on them, alternating between swirls on each nipple. His fingers tapping, pinching and rolling on the free wet nub. Venti writhes helplessly underneath while trying to suppress his moans. His arms have long been freed as Zhongli is petting his painfully hard cock, still within the confines of his pants.
Hugging Zhongli’s head close to his chest, Venti can’t help but let out a moan when he feels a bite on one of nipples. Then, a lick to smooth the pain. Every tug and tweak Zhongli has made to his nipples were sending so much stimulation to his dick that he’s impatient for his own orgasm to rip through himself.
Venti is in a daze, by the time he’s aware, his underwear is hanging on one of his ankles, and there’s Zhongli’s dick, still red and angry right in front of his entrance. Venti wants to squirm away, but before he gets the chance to; Zhongli’s caveman, lust-filled brain sinks his cock right into Venti without any preparation. In shock, Venti tries not to scream. He turns his head to bite down on the pillow he’s been sleeping on and feels that moron still.
‘At least he has the decency to wait.’ Venti thinks bitterly, scrunching his brows tightly together.
“You’re so tight.” He hears Zhongli grunt. “Darling, I don’t think I can stay still any longer.”
“Wha- What are you saying, blockhea- ah!” Venti lets out an involuntary moan, as Zhongli starts moving. Receiving thrust after thrust, the idea of keeping quiet slips Venti’s mind as he starts moaning louder and louder with his eyes shut. Suddenly, there’s a palm covering his mouth to prevent the noises from leaking.
“Better keep your voice down, darling.” his boyfriend breathes into his ear. Not wanting to be caught, Venti shuts his eyes tightly and turns away to the pillow to suppress his moans.
As he opens his eyes, he sees Zhongli’s face, eyebrows scrunched in concentration. Bringing a hand to Zhongli’s chin, Venti pulls his lover closer to his lips to claim them. Pressing their lips together, his tongue darts out to swipe at Zhongli’s lips, it starts off slow and soft, until Zhongli bites down hard on Venti’s lips, tongue licking on Venti’s perfect sets of teeth. There’s a satisfaction that blooms within Zhongli when he hears Venti’s muffled moan as he grants Zhongli access into his mouth. Sucking on Venti’s tongue, Zhongli speeds up on his thrust and fucks Venti a little more erratically.
Venti’s muffled moans are like music to Zhongli. It’s not often his little lover gets to be quiet like this. With two strong arms, Zhongli manhandles Venti, carrying him on both of his arms with them still connected. Knowing how much deeper he would hit inside of Venti as he thrusts upwards, Zhongli flashes a sadistic smile as he hears a small yelp from the petite man.
“Shut up.” Zhongli breathes, as if he wasn’t the one egging and pulling the moans out of Venti. Cruelly, he slows down on his thrusts, pushing himself back into Venti harder each time until a groan escapes out of him.
“Does this get you off, Venti? Knowing my siblings could walk in on us anytime?”
He scoffs when he sees how Venti tries to deny it, eyes squeezed shut and the frantic shaking of his head.
“You’re denying it, darling.” Zhongli laughs quietly. “Yet you’re squeezing on me harder than you usually do.”
Before Venti could snap a comeback, they both hear a knock on the door.
The both of them still, panic surging within Venti. Looking back at Zhongli, the taller smirks as he walks them both towards the door; still connected. Venti’s pretty sure his heart is going to leap out of his throat as he hears Zhongli conversing with whoever is outside of the door.
“What?”
“Da ge!! Feifei and I can’t beat this level!” Xiao yells exasperatedly. “Can you help us?”
“Hm,” Zhongli says, delivering a thrust. Venti braces himself against the door with an arm, the other hand slapped tight onto his face to prevent himself from leaking any obscene sounds. He’s overheated, embarrassment and arousal both affecting his brain. He doesn’t even realise he’s quietly sobbing from the excitement of being caught and pleasure.
“Gege will come to you after Venti gege gets this question right, okay? Why don't you wait downstairs with Feifei?” There’s another hard thrust and Venti’s biting down on his fist, though it does little to contain the moan he’s holding back on.
“Okay!” Xiao replies happily, oblivious to whatever activities his brother and best friend were doing behind closed doors. Zhongli assumes he’s left when he hears small thuds growing fainter.
“Okay, now for the question,” Zhongli says. Hovering over Venti’s back, he whispers:
“Can you come untouched for me?”
Venti knows what the correct answer is. He knows he should answer right now, but the hot kisses and licks on his ear is making his brain turn into mush. Maybe he took too long to reply, because Zhongli is pistoning his thrusts faster and harder. Venti whines as he pushes his hips back to Zhongli greedily, tears threatening to spill out of his eyes.
“Answer me.” Almost cruelly, Zhongli stops moving, earning himself a muffled whine.
“I- I ca-”
“Gege!” A bang on the door jolts them both. “What’s taking the both of you so long?”
It’s Yanfei.
Cursing under his breath, Zhongli wraps a hand on Venti’s neglected cock and starts pumping as he snaps his hips up to Venti’s, feeling the quiver from his lover below him. He can see how Venti is trying his best to not let out any sounds, his pretty eyebrows clenched and still biting on his fist. Zhongli wishes he could capture this on camera, his beloved all debauched, trying to deny his pleasure. He tries to burn the image of Venti crying into his brain before he hears:
“Gege?”
Fuck. He forgot she’s outside. Quickening his pace, he feels Venti tense and not long after come, spurting his seed all over his door. He might have to explain the stain to his parents later but what’s important now is his own release. A couple more thrusts is all he needs before he’s painting Venti’s walls white in his own cum. Pulling out of Venti, he replies:
“We’ll be there soon, Venti gege had some problems with a question.”
“Okay! Don’t take too long!!”
Venti’s still bracing himself on the door with both of his legs spread open. The cum is dripping down, soiling the insides of his thighs. As he turns around to face Zhongli, there’s a glare and in the next second, Zhongli’s feeling the sting on his face as Venti slaps him.
“You fucking idiot.” Venti huffs, offendedly glaring at his boyfriend. “I’m not forgiving you so easily.”
He strides over to the bed where he’s been stripped clean off his clothes with an awkward limp and begins to put them on. Zhongli pulls his pants up and makes himself presentable before going over to Venti to apologise.
“I’m sorry darling, I shouldn’t have acted on my instincts.” He gives Venti a hug from the back, kissing his cheek. “Please, forgive me?”
Rapid knocks on the door interrupts Venti’s reply, followed by two children loudly wailing.
“Gege!! We waited for so long!!!”
“Are you lying to us??”
“Didn't you say lying is a bad habit!! I'm telling mama!!”
Venti snaps out of his shock, untangles Zhongli’s arms around him and scrambles to dress himself. He doesn't bother wiping the drying come in between his thighs, pulls his pants up and buttons his uniform quickly. The only sound coming from zhongli is his zipper going up and him shuffling to the door.
“Ah xiao. Fei fei. Stop it right now.” He says, tone stern. The wailing stops gradually.
Zhongli looks back at Venti, who’s still trying to buckle his belt and soothe out the wrinkles. After Venti gives him a thumbs up, Zhongli creaks the door open and the two little rascals look up at him, little hands pawing at their older brother’s arm as they lead him downstairs. Venti follows suit, praying the fluids within him doesn't leak.
As Zhongli beats level after level with the kids cheering him on, Venti stares into blank space. By the time Zhongli finishes the last level of Mario, Xiao and Yanfei are already fast asleep. Carefully extracting himself away from the couch, Zhongli watches as Venti heads upstairs with a small limp. Feeling a satisfaction bloom within his chest, he smirks and follows his boyfriend.
To his surprise, Venti has actually pulled out his math textbook and started revising. Right. He came to ask him math questions. Sliding next to Venti, he sheepishly asks him what he needed help with. Venti points, and Zhongli starts to explain. Halfway through the explanation, he starts feeling his stomach aching. Ignoring the sensation, he continues to explain before looking at Venti to check on if he got it. Venti smiles, and he continues.
The ache in his stomach continues until he has to excuse himself to the toilet. As he rushes into his toilet, he hears uncontrollable laughter outside.
“Have fun dealing with the laxative laced drink you drank just now, dearest.” Venti coos. “I’m going home. As for your punishment, no sex until finals are over, yeah?”
