Zhongli is greedy when he latches onto Childe's chest, swirling his tongue around the stiff peak of his nipple.

Childe arches from the bed, moaning, head tipping back to rest against the soft pillows. "That's, oh, that's—" It isn't quite new; his nipples are as sensitive as any others and Childe is more than into having them played with and teased, but this—

He'd known there would be changes. Zhongli whispered them into his skin the last time that Childe begged to be bred. I can make it work, he'd said. You'll swell with new life and with it will come other changes. Filthy, filthy words that would turn most red in the face, that made Childe's gut curl with visceral want and need, that made him beg for it.

Hindsight is twenty-twenty. Zhongli did exactly as he was asked, fucking an egg into him, whispering praise into Childe's ear, telling him what a perfect mother he'd be. And there are no regrets—how can there be? Zhongli loves him to the moon and back, to the ends of the Yaoguang shoal, into the depths of the deep sea.

But, with pregnancy came other things; swollen ankles, back pains, the inability to find a comfortable sleeping position in bed. How his joints twinge when he moves even though the egg isn't as heavy as a mortal child, and how he just feels thick in general despite Zhongli's affectionate crooning as he smooths a warm hand over the swell of his stomach.

His pecs changed, melting from taut, hardened muscle into soft, swollen flesh. His nipples ache, stiff with milk, which Zhongli so dutifully laps at. One hand on the right, teasing the rosy bud, flicking it gently as he licks around the other, moaning softly at the soft trickle that beads from the tip.

"Oh gods." Childe bites his lip, squirming underneath Zhongli's touch, rucking about the silk sheets of their bed. It is different. Zhongli's mouth is searing hot as he latches onto Childe. It hurts in a way, a searing pleasure pain that slides down his back, pricking his nerves.

It's the pressure of your milk, said Zhongli earlier that night when Childe whined about the discomfort. Rest assured, baobei, I can help with that.

Zhongli suckles not so gently, teeth grazing the sensitive flesh, tugging. He swallows Childe's milk down, sighing. "Divine," he whispers into Childe's skin, kissing every inch of it that he can reach, "you taste—" He cuts himself off as he dives in for another taste, tongue swirling around a dark and puffy nipple.

He feels it in his gut, pleasure sparking through his veins as it sinks lower. Childe could come from this, just from Zhongli's tongue and how it sweeps over his skin. How he worships his taste, swallowing it down. He's greedy, drunk on what flows from Childe's chest, his moans muffled, breath hot and tepid.

Childe's cock aches, twitching as it lays against his stomach, untouched. Zhongli pays it no mind, swapping to the other nipple, swapping his attention for equal fanfare.

"I'm, oh, I'm—" Childe's voice cuts off with a groan as he jerks when Zhongli bites down, not hard, just teasing. Childe's cock strains, leaking all over his rounded belly. It won't take much. He's right there, so close he can almost taste it. His hips buck, trying to find friction for his hot length anywhere that it can.

Zhongli slips a hand down to pin his hips to the bed with a gentle, but firm grip. Childe whimpers, surrendering back to the mattress, falling still. Zhongli pulls back and squeezes a breast, fingers digging into the soft flesh until it gives. Pearly liquid beads from the tip, dripping down a dark areola, chilling in the air.

Golden eyes watching it like a hawk. Zhongli licks at his lips, tongue darting across the fangs that peek form his mouth. "You should see yourself," he purrs, that glowing gaze falling half-lidded, lost in lust, looking at Childe as though he wants to eat him alive. "Swollen with our child. Milk flowing from your breasts—" He leans forward to lick up the trailing line from the underside of a pec, up and back to the nipple.

Childe's legs tense as he cries out. Zhongli sucks harder this time, coaxing the liquid to freely flow into his mouth, swallowing it down as though he's a man starved. A hand against Childe's stomach, light against the curve, resting there. Thinking, imagining, feeling.

Zhongli moans again, taking his fill. Then back to the other nipple, tongue flicking out to tease it cruelly.

"Oh, oh fuck. I'm—Mhmn." He curls a hand into Zhongli's hair, pulling tightly.

Zhongli grunts but doesn't move, far too enamored with his current task. "Are you going to come?" he asks around the flesh in his mouth. Biting it, just a nibble, his teeth digging into the soft flesh of Childe's nipple. Sparks fly all the way down to Childe's toes. "Be a darling for me. Go on and come."

Childe goes taut at his words. Zhongli's lips as they seal back over the mound of his breast. His tongue that slithers over his skin, wet and drooling. He makes a mess as he slurps at Childe's chest, and fuck, Childe can't stop looking. The pleasure snaps, warm, like the hot liquid that seeps from his nipples, coaxing his body over the edge as he comes all over his stomach.

He moans, his voice raspy. His ass clenches, begging to be filled. His cock twitches, spent and leaking, slick with his come.

Zhongli pulls away to look. Sweeps his hand through the come that coats Childe's skin, playing with it. Brings it to his mouth for a taste as though to compare. "Salty," he murmurs, observing the obvious. He thumbs over Childe's nipple watching the milk leak. "This though—sweet. Like honey. You are so perfect for me."

"Zhongli—"

"Can you come again? Just from my mouth?"

No, he thinks, wriggling in the sheets—but his cock is interested in the thought, tingling with want, already filling out again. Zhongli drags a finger down the length, smearing the come around. It's all so messy, everything is a mess from his leaking chest, to his soiled stomach, to his slick cock already wanting a second round.

"Beg for it," requests Zhongli, feeling a little bit cruel. He rubs over an aching nipple with his thumb.

"Please, please. Again. I want—" Childe swallows, choking on spit and air. "And your cock. Come on, fucking me full this time, and—" He paws at his chest, squeezing his own breast.

Zhongli's gaze turns feral at the display, at Childe moaning with want, drowning in arousal as his eyes prick with tears. Anything, thinks Childe. Anything to satisfy this itch.

A kiss to one breast and then the other as Zhongli soothes him. "I'll take care of you, baobei. Shh, shh." He dips low again to suckle and breast and Childe shrieks, the pleasure this time tenfold with his overstimulation.

And, true to his promise, Zhongli takes care of him. Works Childe open with his fingers until he's a keening, debauched mess that can barely think straight. Zhongli slips in and fucks him slowly, languidly, with rolling thrusts of his hips as his cock drags through his insides; as he laps at Childe's chest, filling him to the brim until he's lost all his words, brain full of nothing but hazy pleasure, nerves set alight with tingling pressure.

Zhongli drags Childe to the edge and pushes him over it; over and over and over, pearlescent milk staining his tongue.
