Zhongli is spread out below him in the bed, pink-faced and sweaty. Scales line his face, dotting his skin. No horns—he isn't that far gone—but the smooth, pale skin of his shoulder bleeds into obsidian. Glittering lines of Geo trail down his arms and curve around his wrists, pulsing like a heartbeat.

Childe smirks. Drags a hand down Zhongli's sternum, dipping through that valley, tracing the hard line of his muscles. Fingers ghost over a nipple, tweaking it, dragging a groan from deep in Zhongli's throat.

"What a sound," he says in a cocksure tone. Childe leans forward, his hand still sweeping over Zhongli's form before settling high over his pec. A scar from where Zhongli's Gnosis once was, spiderwebbing across the skin. He used to hide it, a little self-conscious about the reminder of his divinity and the imperfection left behind in its wake. Childe caught him unawares one day before he could mask it, begging for him to never hide it again.

"Ajax—" Zhongli hisses, head tipping back as Childe rolls his hips, taking his cock deeper, clenching around it. His insides cling to Zhongli's thick length as Childe rides him fast and hard, sweat dripping from his brow.

"Shit, and the way that you say my name." It isn't that Zhongli is quiet in bed, not with his curling words of praise, or heated debaucheries that he whispers right into Childe's ear. But this—Zhongli's breath hitches with every rise and fall of Childe's hips. "Yeah, just like that, fuck."

Zhongli holds him by the waist, claws digging into the soft skin of Childe's sides. He helps him, guiding his hips and pace as Childe moves over him. Childe moans as his cock punches deep, full, and thick in his gut. His thighs tremble as he tries to hold the rhythm because even the sight of Zhongli like this is enough to send him over the edge.

Childe sinks down until his ass meets Zhongli's thighs. Zhongli gasps, loosing a guttural curse as he bucks into him, grinding until Childe swears he can feel Zhongli's cock in his throat. "Oh, oh—"

Zhongli watches him with a half-lidded, glowing and golden gaze. His neck strains, vein bulging. His fingers dig in deeper as he holds on. Holding back. Trying to maintain his cool, to keep from losing himself entirely. Perfect for teasing.

"Are you close?" Zhongli groans in response and Childe smiles. "Heh, you are. Old Lizard." A fond tease, one that drips from Childe's mouth low, like liquid honey. "Am I too much for you? Too young, too fresh?"

"Ajax—"

Childe nuzzles Zhongli's jaw, kissing it. He hums softly, affectionately. "I know—I'm too tight. You can't handle it, being buried so deep. All you can think about is breeding, stuffing me up until I can't think of anything else. I'm too much for an old man to keep up with—"

Zhongli pulls his cock out abruptly and flips them. Childe's easily overpowered, not that he'd put up a fight. He knows that Zhongli isn't too old to satisfy but it's fun to poke at the beast. Zhongli's weight is heavy against him as he presses Childe into the mattress, chest shoved against the sheets.

"Bold words," he whispers into Childe's ear, breath searing hot as he licks across the shell of it with a forked tongue, "coming from a boy who loses himself so easily. Tell me, Ajax, how close are you, hm? If I slip back in, just how long will it take until you come?"

Not long. Childe was close, the fire in his gut blazing as he barrelled towards an orgasm. It's been dulled these last few minutes as Zhongli strings him along, making him wait. "That's—unfair."

Zhongli spreads his asscheeks wide and looks. Takes his time, sweeping his thumbs over his loose, oil-slick rim before slipping them in. "Naughty," he says, tugging at Childe's hole, stretching it to peer right into his insides. "Good boys aren't so easy in bed, right?"

"I'm not—Zhongli."

"Or is it that you're only easy for me?"

"Yes!" cries Childe as Zhongli drives three fingers in, fucking his sloppy hole, watching the way that it just swallows them down. "Fuck, fuck—"

"You shouldn't tease me so readily, baobei, because it only makes me respond in kind."

Which Childe knows and loves, Zhongli's deep voice cooing terribly dirty things into his ear while fucking him raw. The love-making is wonderful but it's fun to push his buttons and have to pay for it.

Zhongli slams his cock back into him hard enough to knock Childe's breath loose. Childe moans, drowning in the silk sheets and the earthy scent of Zhongli that clings to them. The hard drag, slick and wet, the slap of sweaty skin, and Zhongli's balls against his own.

"Oh, Gods. Oh, oh—"

"You mentioned the sounds that I make, but Ajax, I wish you could hear yourself. It's as if you are hanging in the stars, you're so lost. Does it feel that good?"

It feels better. Zhongli's cock carves a home into his ass as though it belongs there. Childe chokes on a moan as he fucks back against him, doing his best to meet every hard thrust of Zhongli's hips. Desperate and needy. Childe needs this, to come with Zhongli buried deep, Childe's name tumbling from his lips. "Full," he murmurs, "So, so full, fuck."

"So tight for me," says Zhongli, "but not too tight for this old lizard."

Oh, he is—Childe definitely is and he knows it. He has Zhongli wrapped around his damn finger in bed and he uses that to his advantage. Zhongli grunts as he fucks him, fingers tight around the sharp jut of Childe's hips as he pulls him into each thrust, but he hides it well between silver-tongued words that leave Childe's heart skipping a beat.

"You love it," he says, voice mildly muffled by the bed. Childe turns his face. "You love me."

Zhongli pauses, his cock settled deep, twitching slightly. He leans forward, nuzzling the back of Childe's neck, fangs dragging across the skin there to nip at it lightly. Frames Childe's head with charcoal-black arms, elbow digging into silk. His chest rests against Childe's back as they melt together, legs tangled, bodies entwined, Zhongli's dick shoved into him as far as it can go.

"I do. Celestia, you cannot begin to dream how much I love you." Zhongli doesn't fuck Childe hard and fast, now, he's slowed to a crawl, opting for heavy thrusts that drag through Childe's core. His cock is hot, branding him. Zhongli ruts with the perfect angle, the tip pounding into Childe's swollen prostate with every slide.

And those words; Childe was content with his teasing, but fuck, if the romantic platitudes aren't what always do him in. His dick aches, hard, trapped between his belly and the sheets. Zhongli's face is close, cheeks pressed together as he leans over Childe's shoulder, scales catching on smooth skin.

"Gods, yeah—" Childe moans.

"My darling," says Zhongli. A thrust of hips. "Baobei." Another thrust, this one stuttering, his pace lost in the heat of their passion. "What was it you said earlier? That all I think about is breeding you? I do—oh, how I do. Swollen and rounded with my come, with my—" Zhongli cuts himself off, refusing to finish the thought.

That's a new one. The breeding kink, not so much, but— "With your what? Come on, old man. Tell me."

Zhongli moans, the sound liquid in Childe's ear. "Laogong," he says, the foreign word rolling off his tongue. Childe has never heard this one, has no idea what it means but he loves it all the same, keening at the sound of it. "Fuck, you're—Mhm."

"I'm—I'm—"

Zhongli comes first, groaning, cock swelling as he spends himself inside Childe's ass. Wet, hot warmth; being plugged full. Childe sinks into the sheets as Zhongli plasters himself close, words of love pouring into his ear as he rolls his hips gently, riding out his orgasm.

He hikes Childe's hips up slightly, a hand sliding underneath him. A hand, tight against Childe's cock as he gives it a few jerks. "Perfect for me. So tight, so handsome, and all mine. My precious Laogong."

The word feels right, sinking into his chest, settling right near his heart. Childe will ask later, but for now, he fucks into the clenched grip of Zhongli's hands, shuddering as arousal threatens to overtake him. "So good," he hisses. "Archons."

Zhongli chuckles against his nape, endlessly entertained by that particular curse. He jerks Childe's cock. "Come for me. Show an old man just how you do it."

Terrible dirty talk. Childe is caught between laughing and crying but comes, all the same, flying over the edge as he spills into Zhongli's hand. Zhongli tugs him through it, fucking into him gently, stroking his cock into overstimulation. All the while Childe writhes in the sheets, toes curling as his ass clenches so tight that Zhongli loses his breath, his length still buried deep.

"Fuck." Zhongli so rarely curses, usually in moments like this where he's wholly overcome.

Childe finally laughs, and says, "See? You are old—"

Zhongli thrusts into him, cutting off his tease, cock already hardening to go again. "Old, but not infirm," he teases. "Tell me, boy—how long until you're ready to go again? Because I could fuck you like this all night long."

A challenge. And Childe is a man who cannot turn away from such a thing. He grinds back against Zhongli, goading him on. "Are you offering to put me into my place? Because, yes."

"Yes, what?"

Childe grins as he looks back over his shoulder, meeting a dangerous golden-eyed gaze. "Yes, please. Didn't you want to breed me?"

Zhongli leans back, smirking. Smooths a hand over the swell of Childe's ass, spreading a cheek to take a look. Childe can feel the way come leaks from his hole, around his dick. Zhongli slides his thumb through it with a soft hum. "Oh, it'll be my pleasure," he says, hiking his hips up for a better angle.
