"What's this?"
Childe finds himself smirking the moment Zhongli steps close. He's pressed against the counter, Zhongli's chin against his shoulder.
"Cookies," says Childe. And yes, there are cookies. No, that isn't what Zhongli is talking about.
Zhongli's hand finds his side, fingers slipping underneath the edge of the lace. "Ajax," he whispers into his ear, "I do think that you wore this on purpose."
"What makes you say that?"
Zhongli's hand slides further south, following the swell of Childe's ass. "You're naked underneath."
"Oh? I didn't notice."
Childe laughs as Zhongli spins him around. The edge of the counter digs into the meat of his ass, but Childe is focused on everything else—the drag of Zhongli's hand on his skin; the soft golden glow of his eyes as they narrow, half-lidded with lust; the purr of Zhongli's chest when he leans close for a kiss.
"You tease," he says against Childe's lips. "Always teasing me."
"You make it so easy, you know. All I have to do is wear an apron and nothing else, and that old lizard brain of yours lights right up."
"How cruel."
"All that complaining," says Childe, "when you can put that mouth to better use."
Zhongli pulls back and tilts his head, a rather feral grin spreading across his face. "You test me, Ajax."
"I know."
"You'll reap what you've sown." Zhongli drops to his knees before him.
"Yeah," agrees Childe, spreading his legs in anticipation. He's hard, his cock tenting the flimsy apron.
Zhongli laughs against him, nuzzling his length through the soft cotton. His fingers dig into Childe's thighs as he settles between them. He kisses the wet fabric that rests against the tip. Zhongli brushes his knuckles over the line of Childe's hip, tracing the lace at the edge of the apron.
"Come on," goads Childe, curling a hand around the back of Zhongli's head.
Zhongli slides the cotton away, revealing inch by inch of skin. He peppers kisses over scars and freckles. Traces the crease of his groin with his nose, inhaling deeply before nipping at the spot where Childe's cock begins.
"Zhongli."
"So impatient." As if Zhongli isn't. He bites at the base of his cock, which pulls a groan right from the back of Childe's throat. Infuriating but—well, he asked for it. Zhongli licks down the entire length of his cock. His tongue swirls around the tip, sliding into the slit, tasting the precome that beads there.
He takes his damn time, lapping at Childe's cock as if it is a delicacy. His tongue traces the vein down the side. His hand slides over the base, stroking it.
Childe pulls at his hair, his legs tense. It's good—gods, it's good. But he wants more. "Please, Zhongli. I—"
"Wore this apron, hm?" Zhongli kisses the tip sweetly. "Thought that I would give in?"
Well, he did. Zhongli prostrates before him, knees smarting against the cold and hard floor, nosing at Childe's cock. Childe cups his chin and drags a thumb across Zhongli's bottom lip. Zhongli's mouth opens, his tongue lolling out, the forked tip on display. He's half-lidded, watching him back with a molten gaze.
"Gods, look at you," murmurs Childe, tugging Zhongli's face towards his dick. Zhongli snorts when he presses the tip of his cock to his tongue. "Be good for me?"
Zhongli answers by swallowing his dick, mouth wet and tight around him. Childe sighs, brushing Zhongli's bangs back as he just sinks right in. Zhongli moans around him, eyes rolling back, and nostrils flaring. His fingers dig into the meat of Childe's thighs, barely-there claws pricking the skin as he bullies his way further down.
"Wait, wait—"
He does not wait. Zhongli just smirks around Childe's cock the moment it hits the back of his throat, his nose nestled into the coarse auburn hair at the base of his length.
"Fuck," curses Childe. He pulls at his hair to tug him off, but Zhongli is too strong, nailed to the ground like a solid boulder. An immovable mountain with his own whims. You'll reap what you've sown. An astute warning that Childe laughed at, thinking he could pay the price.
He's wrong. He's going to die from the heat of Zhongli's mouth and the way that he's just sucked his cock right down. How he bobs his head and slides his tongue against the underside to tease the curved edge of his dick. Zhongli is relentless in what he does; every sound that he makes, every movement, swirl of his tongue, jerk of his hand—they're all carefully calculated movements that pull Childe right to the edge.
Childe thrusts into his mouth and Zhongli encourages it, holding Childe by the thighs as he pulls at him. A keen whine as he slips deep. Zhongli takes it and swallows him whole. His thumbs pet circles into the jut of his hip bones as he works his devilish magic.
The apron was a terrible idea. He'd thought Zhongli would just press him into the counter and rail him into the next morning, but no. This is what he does; he kneels before Childe, casts away his divinity, and worships him like he's the god instead.
"Holy—mhmn, I just—Zhongli. Zhongli—"
Zhongli pulls off and strokes his cock. Kisses down the length and praises it, whispering affection right into the tip. "So perfect. Right length, the right heft. Perfect for—"
"Don't say it—"
"Breeding me, yes?"
Childe drags a hand down his face. He feels the way that his cheeks burn as he thinks about it; Zhongli, face down in their bed and his ass tight around his cock.
Zhongli wears a dangerous grin. "Oh, you like that thought. Would you like that? Fucking me full until it takes?" Childe's cock twitches which makes Zhongli give a hum of approval. "Later then, in our bed. You can lay me out and we'll revisit the thought. For now—" He swirls his tongue around the head of his cock before sinking down once more.
Childe holds him by the cheeks and fucks in. "Yes, yes."
The sight of Zhongli is sinful, spit pooling at the corners of his mouth, dripping from his lips. He's uncaring of the mess, or the way his eyeliner is smeared, he just looks up at Childe, adoration on his face. His mouth and hand move in tandem, trying to drag Childe right into his orgasm.
Which will work—how can it not?
"Fuck, it feels good. Just like that, keep—yeah." Childe brushes his bangs back and fucks Zhongli's mouth. And Zhongli just moans, eyes slipping closed. Takes it like he was made for it, lips stretched obscenely around his thick cock. "And you call me the pretty one," he mutters, smoothing a thumb over the arch of Zhongli's cheek.
It takes two more thrusts for him to come. Zhongli takes it in stride, expecting it, knowing Childe was close from how his thighs shook, and the tight grip on his hair. He groans, swallowing Childe's come, grinding his hand down against his own dick, hard in his trousers, strangely debased for a man usually so prim.
When he pulls off, Childe's spend spills from his mouth. Zhongli catches up, sweeping it back to his lips. Then he laps at his cock, licking away stray strands and Childe nearly loses it all over again.
"Ajax, I want—"
"You were supposed to fuck me, you know. That was the point of being naked in the apron."
Zhongli leans forward, resting his forehead against Childe's thigh. Catching his breath. Squeezing at his own cock to stave off whatever pleasure threatens him. "There's always plenty of that. I want—" Zhongli's voice is raspy from the beating his throat took from Childe's cock.
He stands abruptly and boxes Childe in against the counter once more. Zhongli grinds into his thigh, his thick erection hard against it. He moans softly and hides his face in Childe's nape. "Don't you want me on my knees again? Only this time in our bed, swathed in silk, ready for the taking? Darling, I want you to fuck me."
If words could kill, Childe would've ascended to Celestia right then. He swallows thickly and takes a deep breath. Zhongli's hand is already around his cock again, squeezing it until it twitches with renewed interest.
"I—yeah, okay."
They chase each other through their home with wandering hands and squealing teases. And then, once in the bedroom, just as Childe's hands go for the knot of the apron, Zhongli's voice stops him.
"No, no—that stays on."
