Work Text:
It was a morning like any other when the thought crossed Childe’s mind. They had been lounging in bed together, still unclothed from their activities the night before.
Childe is tracing the glimmering golden trails that run across Zhongli’s arms, when he comes to a realisation. “I wish I’d known you during the Archon War.”
Zhongli stares at him, frowning. “No, you don’t.” He casts his eyes towards the ceiling, seemingly trying to find the proper words to chastise Childe’s foolishness. “It was not a good time to live in. People died - more than I could ever list.”
“That’s true.” Childe concedes. His fingers tap at the geo markings on Zhongli’s forearm, rubbing at the tapered lines. “I wish I’d known you before the Archon War, then.“
Zhongli reclines against the pillows, watching Childe stroke the golden pattern, following it down to Zhongli’s wrist. He waits until Childe lets go before he speaks. “I’m afraid to tell you that we would never have met. I had little interest in mortals back then.”
“Hm.” Childe plays with the hair spread across Zhongli’s back. His fingers start plaiting the strands absentmindedly - an instinct left over from doing his sister’s hair. “Something tells me I could catch your attention.” He lowers his lashes, fluttering them jokingly.
Zhongli laughs quietly. “You would never be in Liyue in the first place. When would you get the opportunity?”
“Maybe I could have immigrated there.” Childe shrugs, too lost in his fantasy to care about logic. “I could’ve caught your eye when I was working hard fishing.”
“Ah, fishing, the most erotic of activities.” Zhongli quips, but Childe is on a roll.
“Don’t you think it would be hot? I could’ve been your concubine.”
A touch of red rises on Zhongli’s cheeks. “The Adepti never partook in such practices.” He answers stiffly.
This doesn’t deter Childe. “Well then, I could be the first. I’d be there for you when the fighting was over, to bathe your sweaty, bloody body with my tongue.”
“Childe.” Zhongli‘s voice is becoming strained. He can hardly believe Childe has the gall to say such crude things aloud.
“Say, the Adepti really believed in your power and superiority, huh? They would probably think that you were bending me over every night... But behind closed doors, you’d be begging for my cock. Their revered Prime Adeptus, getting fucked until he was gasping and desperate.”
“Irreverence towards the gods is not something I appreciate.” Zhongli cuts in, tone disapproving.
Childe snorts. “Well, that’s not really true, is it?” He leans closer, lowering his voice. “Some might say that the way I hold you down and force you to take it is irreverent. And you seem to enjoy that quite a bit. More than quite a bit.” He smiles to himself as he remembers the numerous noise complaints they’ve received from Zhongli’s neighbours.
“You are intractable.” Zhongli huffs, but wry humour creeps across his face. “Has it occurred to you that I wasn’t always the man you see before you now? What makes you certain that I was always so pliable?”
Childe’s heart rate picks up. “Well, even if you were a little tougher, I’m sure I could break you down.”
Zhongli’s eyes flash. “Break me down?” He repeats, slow and deliberate. His demeanour has changed, suddenly alert.
“Well, yeah. I’d break down your walls and convince you to consider me through my good looks and charm.” Childe wiggles his eyebrows jokingly.
Zhongli chuckles behind his hand. There’s a new, rough quality to the laughter that makes Childe’s pulse jump. “That is certainly true. But I believe you may be underestimating my restraint.”
In one sudden movement, Zhongli has Childe under him. He sits back, placing himself directly over Childe’s crotch.
Zhongli gives him what some would call an old-fashioned look - ironic and humorous, with a smidgeon of playful disdain. “No, I think if you managed to charm your way into my bed, I would be the one taking my pleasure from your body. There would be no begging on my part. I would ride your cock until I was satisfied or you could take it no longer.”
“Fuck.” Childe breathes, tilting his hips up. He rubs against where Zhongli sits on top of him, cursing when his dick slips between Zhongli’s ass cheeks. The friction is both excruciating and immensely enjoyable.
With a firm hand, Zhongli pushes Childe’s hips back down onto the bed. “Whilst the Adepti have never practiced concubinary, I’m not unaware of its mechanics.” He traces his hand upwards, running across Childe’s scarred torso. “And if I read correctly, a concubine’s role is to serve, no?”
Childe swallows. “Yes.” His fantasy is abruptly changing shape, until it morphs into the picture Zhongli is painting. Him, flat on his back, just like he was at that moment. Zhongli, in all his godly glory, holding him in place, bouncing up and down on his dick. Setting a ceaseless pace, unheeding of Childe’s groans and grunts.
“That is not what you imagined, is it?” Zhongli murmurs, smiling. “Perhaps you misunderstood the rules of such courtships.”
“It’s what I’m imagining now.” Childe blurts out truthfully. He can’t get the idea of Zhongli mercilessly fucking himself using Childe’s cock out of his head.
Zhongli blinks. Surely he can’t be that surprised - Childe’s erection has been rutting against the soft dips of his ass throughout their conversation.
Then, he smiles, abruptly grinding back on Childe’s dick.
The yelp Childe lets out is almost embarrassing. Zhongli exhales, amused. He continues dragging his ass over Childe’s crotch, making torturous little circles with his hips.
“Do you want this?” He rasps, leaning down so his hair falls over his face.
“Yes.” Childe answers immediately.
Zhongli withdraws suddenly, leaving Childe’s hips bucking into nothing. He lies back against the cushions and spreads his knees. “Serve, then.”
Childe knows that Zhongli is just humouring this impulse of his, and allowing him to indulge in a fantasy. But he can’t help but envisage those words delivered as a sincere order. One he would obey without question.
He slides forwards, fingers grasping Zhongli’s thighs.
Zhongli cups his cheek, guiding him downwards. Childe realises what Zhongli wants and readjusts his position, so his head hovers above Zhongli’s cock.
He blows out a hot breath of air, grinning when Zhongli twitches, eyes fluttering shut. Always so sensitive, even when playing at dominance.
With one smooth motion, he takes the head of Zhongli’s dick into his mouth. He tongues at the underside, tracing upwards over the slit. The harsh little gasps that Zhongli lets out at the stimulation are the best reward he could ask for. He hollows his cheeks, sucking hard, and Zhongli’s thighs clamp shut around his head. He moans under Childe’s ministrations, falling back against the pillows.
A hand finds itself in his hair, and before Childe knows it, it’s urging him lower. He accepts, sinking down on the cock, swallowing as he moves.
Zhongli gasps out a choked sigh, hips jerking. His thighs part again, quivering. Childe doesn’t falter, humming around the length. Zhongli groans softly.
Though Childe’s mouth is occupied, his hands are free to wander. And wander they do, caressing Zhongli’s hipbones and palming at his ass.
Then his fingers dips lower, running over Zhongli’s balls. He’s so open, so prone with his legs apart. Childe’s fingers slip backwards, until he’s brushing the tight furl of Zhongli’s hole. It’s still a little puffy from the previous night and the thought makes Childe suck harder. Zhongli doubles over, cupping Childe’s head closer and moving his knees open further. Zhongli’s ragged panting reaches Childe’s ears and he takes the initiative.
He presses the pad of his finger against Zhongli’s rim. Then, he puts the slightest hint of pressure behind it. Just short of pushing in, but enough to make Zhongli shiver in anticipation.
With a little wiggling, Childe’s finger forces its way in. By all logic, it shouldn’t be this difficult - Childe was inside Zhongli less than twelve hours ago - but his hole flutters around Childe’s digits, hot and tight as a vice. Feeling that trembling passage around his fingers makes Childe salivate, and the spit drips down Zhongli’s shaft, pooling on the sheets.
“Childe. Childe.” Zhongli murmurs, caught between the sensation of Childe’s mouth and his fingers. He’s half-forgotten that he’s meant to be the one commanding the pace, but he remembers just in time to grip Childe’s hair again.
Childe hums in acknowledgment of the silent request and Zhongli’s legs spasm, feeling the vibrations around his cock. He thrusts upwards, moaning.
And then, when Childe presses his finger deeper, something suddenly spurts into the back of his throat. Zhongli’s hold on his hair loosens.
Childe pulls back, gulping down the cum.
Zhongli gazes down at him, slightly dazed. It seems that the orgasm took him by surprise as well. His lips open and then close, wordless.
Childe grins, wiping his mouth. He twists his finger inside Zhongli as he withdraws, making him cry out at the overstimulation.
Childe’s chest is puffed with pride. The speed at which Zhongli came is stroking his ego. “What’s the verdict? Would you find that relaxing after a long day of combat? Have I served you sufficiently?” His tone is conversational, as if he wasn’t just sucking Zhongli’s soul out through his dick.
Zhongli blinks, then throws an arm over his face, exhaling heavily. His hair is adorably mussed.
Childe snickers. “What happened to the Prime Adeptus’ unshakable restraint?”
Zhongli sighs. “If you give me a moment to catch my breath, I’ll show you.”
Childe‘s eyes widen. “You will?”
Zhongli slowly sits up. He smiles disarmingly. Then, he moves forward, pushing Childe back and pinning him down on the bed. “I will.” He confirms, voice low. “Surely someone with ambitions to become my concubine can serve a little longer?”
Childe nods, making it plain that he’s revelling in this fantasy they’re playing out - of being Zhongli’s paramour.
Zhongli reaches back, taking Childe’s cock in his hand, still hard and dripping. Childe hisses when Zhongli guides it to his hole, teasing around the rim.
As he sinks down on Childe’s dick, he murmurs one word. “Mine.”
Childe’s eyes flutter shut, a groan bursting from his mouth. He can picture it - waiting in Zhongli’s abode for him to return, and helping fuck away his troubles. His. Zhongli’s. Morax’s.
Zhongli rises, until Childe’s cock almost slips out of him. Then he pushes down again, riding him rough and fast. Childe pants, jerking upwards every time Zhongli squeezes around him.
He curses when Zhongli’s hole clenches, head spinning. A sharp ache suddenly shoots through his stomach and his hips stutter. He groans, orgasm ripping through him without warning.
Zhongli freezes. “Ah.” He rises up on his knees and cum runs down his thigh.
Childe begins to laugh, breathless and exhilarated. “Alright. Maybe I need a little more practice before I’m considered for the title of concubine.”
“Don’t be ridiculous.” Zhongli responds, untangling their limbs. He leans down, kissing Childe’s jaw. “You’re already far more than that to me. I love you.” When he draws back, he’s smiling. “But we can always practice, if you insist.“
Childe gulps in eager anticipation. “I do. I do insist.”
“Well, I’ll happily oblige. Your fantasy is really quite enjoyable.” Zhongli lays another kiss against Childe’s cheek, easing himself to his feet. As he walks towards the bathroom to clean up, Childe’s cum spills down his thigh in a slow trail.
Childe lies back, thoroughly satisfied. He must be luckiest man in all of Teyvat.
