Childe gripped at the sheets tight enough to have his knuckles turning white. His blue eyes were half-lidded in utter pleasure and his thighs kept trembling helplessly. Never before had he experienced such intense sex. Unrestrainable groans fell from his lips while Zhongli bounced on his cock, relentless.
His lover looked absolutely gorgeous, with his hair untied and geo markings shining on his arms and legs. His antlers and tail were on full display, as well as his two dragon cocks that were leaking pre-cum all over his stomach. Zhongli was throwing his head back, moaning continuously as he impaled himself on Childe’s length. His pussy was dripping wet with slick and seed, which made for a smooth and inside glide.
Pinned underneath him, Childe barely had enough stamina remaining to thrust up into him in sync with his rapid rhythm. All of his sensations were amplified, to the point where even the lightest brush against his skin sent his nerves on fire. It took him ridiculous amounts of concentration just to caress Zhongli’s engorged clit with his thumb. Archons, how could his body hurt so much yet feel so good?
He still remembered clearly how embarrassed Zhongli had been, when he had brought up the matter of his heat. He didn’t even ask Childe to assist him with it at first. Not because he didn’t want him, far from it, but because he feared it would be unfair to require of his human lover that he satisfied his divine needs. He had described himself as being insatiable while in the throes of heat, and Childe was starting to realize just how accurately the term fitted his current behavior.
The well-mannered consultant of the Wangsheng Funeral Parlor was gone, replaced by a lewd, debauched creature that acted on instincts only. He growled in protest whenever his pussy wasn’t stuffed full, but started purring uncontrollably the second Childe slipped the head of his cock inside him and roared in absolute delight at having cum shot straight into his womb.
It shouldn’t have been a surprise to Childe. Zhongli had thoroughly warned him about how his heat would cloud his judgment and about what he should expect. Still, nothing could have prepared him for the real thing. When he had offered to pleasure him through it, Childe had vastly over-estimated his own capacities.
How foolish he had been! It was a good thing Zhongli had insisted to have him drink an adepti potion brewed specifically for such an occasion. Without its effect, his cock would have probably gone soft hours ago. Childe couldn’t even remember how many times he had come already. Each orgasm felt more devastating and disorienting than the last, but he refused to back down.
He had promised Zhongli that he would see him through his heat, and he intended to keep his word. He could still picture their pinkies linked together, as well as Zhongli’s timid joy blooming into full elation the moment he realized that this time, he would not have to suffer through it alone. That the man he loved would be there to mate with him. And so, Childe gritted his teeth, determined to rise up to the challenge and to keep pleasuring Zhongli despite how his own overwhelmed body begged him for mercy.
“Yes… Fuck, you’re so good to me…” Zhongli encouraged him eagerly.
Ever since the beginning, he had been babbling mindless praises which went straight to Childe’s arousal. And while they had felt better deserved when he had been pleasuring Zhongli with his mouth or fucking him into the mattress until he cried in ecstasy he still welcomed them gladly, because he knew they were sincere. Childe could tell from his arched back, his quivering pussy and his blissed-out expression that Zhongli was loving every second of his heat.
It didn’t matter to him that Childe could do little more than lay on his back and allow his body to be used, not when Zhongli could still ride his cock and bring himself to orgasm again and again and again. The lust that veiled his golden eyes made it clear that as long as he would be fucked and bred, he would remain content.
A jolt of electricity ran through Childe’s whole body as Zhongli’s cunt spasmed around him, milking his cock for what had to be the hundredth time. Or at least, it felt like it. To his surprise, he spurted copious amounts of cum into his mate’s already flooded womb, despite how spent he felt. Probably another effect of that adepti beverage. Above him, Zhongli swished his tail happily, overjoyed to have his belly pumped full of fertile seed, but he hissed in contrariety when some of it started dripping out of his pussy, right where his and Childe’s body joined.
“Need… More…” He whined, lifting his hips up, and the next moment, he was lowering himself on the Harbinger’s cock once again.
More. Childe ached to satisfy Zhongli’s, to give him what he wanted, no, needed, but he was held back by the limitations of his own body. Even using his Foul Legacy form in battle didn’t make him this sensitive and exhausted. Although, now that he thought about it, there actually was something else he could do to enhance Zhongli’s pleasure. Something that usually had his sweet consultant howling in bliss, even when he wasn't subject to his heat.
His fingers left his lover’s clit and moved up to his stomach, leaving behind a trail of slick and cum in their wake. Droplets of Hydro and sparkles of Electro danced around his hand for a second, until Childe guided them onto Zhongli’s skin. There, they converged to form a pattern so familiar to Childe that he could probably recreate it with his eyes closed.
A Riptide mark.
It pulsed at his command and the elemental energy gathered in it seeped into Zhongli. His pussy, cocks, clit and womb soaked it all up, which increased their sensitivity tenfold.
The next time Zhongli dropped himself on Childe’s cock, he screamed and trembled, all from sudden bliss, as his most intense orgasm so far was ripped out of him. His twin lengths twitched under the delicious onslaught, splattering cum splattered all over his stomach. Underneath him, the Harbinger writhed in ecstasy too as his mate’s pleasure led to his own. He let his head fall back on a pillow, just as his hand migrated to Zhongli’s hip so he could hold onto it.
A sharp sting on his chest, though not entirely unpleasant, distracted him from his high. Childe’s face went pale when he realized that Zhongli’s nails had turned into sharp claws, not because he disliked having them scratch at his skin, but because…
Because it meant that so far, Zhongli had managed to maintain some semblance of control, and hadn’t gone completely feral yet. He had still been somewhat in control, right until now. Childe had yet to discover the worse he could do.
Damn, this was going to be a long night.
After that point, everything became a blur of overwhelming pleasure in Childe’s mind. When he woke up after Zhongli’s heat had passed, only one clear memory stood out from it all. He had managed not to pass out until his companion did as well, but barely. He winced as he remembered how he had been by the end, with his body limp and his mind barely able to form coherent words, lacking even the strength to raise his hand to stroke his partner’s cocks.
And to top it all, Zhongli was already dressed and awake, looking all pretty and proper, as if he hadn’t just been through the wildest sex Childe had ever experienced.
Not to mention that Childe hadn’t even been lucid enough to clean Zhongli up or to offer him a glass of water afterward. Yeah, what a great boyfriend he made…
“I’m sorry,” He apologized, his voice still raspy. “I should have taken better care of you.”
“Better care of me?” Zhongli repeated. He sounded amused. “I failed to see how you could have accomplished such a feat, taking into account that of all my partners, some immortals included, you are the first and the only one who managed to withstand my heat until its very end.”
“Wait, do you mean…”
Zhongli sat next to him on the bed and nodded. His lips were stretched in a content smile and there was a dreamy look in his eyes.
“Yes. No one has pleasured me like you have, Childe. Oh, and there’s also this.”
He took the Harbinger’s hand in his and guided it to his stomach. Even through his clothes, Childe could feel how his belly remained swollen with his cum, just like he noticed the familiar buzz of his Riptide mark. That discovery left his mind reeling.
It made no doubt to Childe that Rex Lapis, the Prime Adeptus, former Geo Archon, could have gotten rid of both in an instant, had he wished to.
Which meant that Zhongli had deliberately chosen to keep his womb full of his seed and to wear his mark on his skin.
Suddenly, Childe felt like the luckiest guy in all of Teyvat.
“I cannot be entirely certain yet, but… I believe that our mating has been successful, all thanks to your dedication. I would not be surprised to be already expecting, since you have left little part of me untouched.” Zhongli added a bit bashfully.
They had talked about that beforehand too. For a half-dragon like Zhongli, pregnancies were highly unlikely, but not impossible. Childe knew this could happen. Hell, he wanted it to happen, and so did Zhongli.
And he was determined to give his lover everything he might desire.
“Do you want to mate with me again? To make sure it takes?” He offered.
Zhongli immediately perked up at the suggestion, although he visibly tried to contain his excitement.
“This soon? Aren’t you sore? I do not want to push you too far or to make you uncomfortable.”
“Do not worry about me. I’m sure I can find enough energy to make slow, gentle love to the father of my future children.”
Zhongli chuckled at his partner’s hushed words, although his seductive tone did not leave him indifferent.
“And to think I believed myself the insatiable one.”
“Oh, I’ll show you how insatiable I can be,” Childe warned, a wide grin on his face, before dragging Zhongli into bed with him.
Because while he loved to have Zhongli riding him, he also couldn’t wait to savor the sight of his mate splayed out underneath him, desperate for his kisses and his touch.
They were in for another long, long night. Or maybe day. Childe wasn't sure. Their curtains were closed, making it impossible to discern whether the sun was shining outside or not.
Childe didn't care either way. At the moment, only one thing mattered to him:
Sating all of Zhongli's desires once more.
