Childe held tight onto Zhongli's shoulders, eyes half-lidded in pleasure as his lover moved inside him. The Eleventh Harbinger, pride of the Fatui, moaned shamelessly with each thrust, legs wrapped around his partner's hips, more than happy to let his body surrender to his. Trapped between their bellies, his hard cock was already dripping pre-cum, even though it hadn't even been touched yet. His nipples ached pleasantly from being sucked and played with earlier. No matter how hard he tried, he couldn't remember the last time someone had made him feel this good.
Not that he meant it as an insult to the few people he'd shared a one-night-stand with. He'd had fun with them, but what Zhongli was putting him through... It was simply mind-blowing. Was his body respond so eagerly to his touches because of how amazingly skilled he was? Or did it feel so different because, for the first time, and despite his best judgment, Childe was offering himself to someone he had grown deeply and truly attached to?
Stumbling in bed with Zhongli wasn't part of his plan. The Tsaritsa had sent him to Liyue with a mission to fulfill, and Childe shouldn't have let himself be distracted. He'd tried to resist Zhongli's charms, he really had, but it was a losing battle from the start. And then, he'd made the mistake of showing up at the consultant's home unannounced to discuss some urgent business matters with him, disturbing him in the middle of a shower.
Zhongli had welcomed him wearing nothing but loose, black silk pants. As long as he lived, Childe would never forget that sight. The rivulets of water dripping down Zhongli's defined chest, his long, untied hair wet and sticking to his skin, the scars that littered his body, an obvious testament to his strength... It had only taken one glance for all of Childe's resolutions to crumble.
Now, as he writhed underneath Zhongli, he couldn't even remember what imperious matter had brought him before the consultant. Nothing mattered anymore but the delicious drag of his cock inside him. Childe gasped when Zhongli untangled his legs from around him, just so he could bend them close to the Harbinger's chest and bury himself even deeper inside him. In doing so, he filled him perfectly and pressed against all the right spots, which had Childe trembling in bliss.
Zhongli kept tormenting him this way for a few more seconds, his thrusts long and slow, until he stilled inside him. Childe whined in meek protest when he spilled copious amounts of cum deep within his body. Not that he disliked the sensation, but it wasn't supposed to happen so soon! If Childe didn't know any better, he would have sworn Zhongli's body was built for war. He couldn't possibly have so little stamina!
His eyes snapped open in frustration. It couldn't be over, not already, he refused to allow it! He wanted to come around Zhongli's cock, to be pushed past his limits, to have him use his body until he couldn't take it anymore. However, before he could voice out his dissatisfaction, Zhongli resumed his thrusts with renewed vigor.
Childe whimpered in pleasure and confusion. It should have been impossible, but Zhongli was still hard, and still pounding into him relentlessly. Maybe he'd been mistaken? Surely, that could be the only explanation as to why Zhongli hadn't gone soft. Childe decided to put the question aside, in favor of focusing on his own building orgasm.
He closed his eyes as wave after wave of pleasure pooled into his belly. Each roll of Zhongli's hips set his nerves on fire. His toes curled, his back arched and in one last moment of lucidity, he realized he was going to come untouched, just from being fucked, just from having that one spot inside him assaulted again and again. His vision went white and he cried out his ecstasy as his cock spurted cum between their bodies, a few, scarce drops reaching high enough to splatter on Childe's face.
He spasmed around Zhongli, just like he had previously hoped he would, making his partner grunt in pleasure as his walls hugged him tight. His thrusts became more erratic, then stopped completely as he released his seed inside Childe. This time, there was no denying it. His belly even bulged a little with it, which had never happened before, but the Harbinger was too blissed out to care. He fell back against the soft sheets, basking in the aftermath of his orgasm.
Childe sighed in contentment when Zhongli wrapped his strong arms around him, manhandling him until he was sitting in his lap. He let himself be dragged into a sloppy, heated kiss. A shiver ran through him when they parted and Zhongli caressed his cheek tenderly, staring at him with sheer adoration in his eyes, as if he was worth worshipping. Childe hurriedly joined their lips again, just so he wouldn't have to look too closely into his own feelings.
A gasp of surprise escaped him when Zhongli thrust up into his still-sensitive body. Childe's softened cock twitched helplessly at the sudden sensation. His legs trembled from the slight overstimulation. Childe failed to comprehend how he had recovered so fast from yet another orgasm. Fuck, Zhongli didn't even look tired, and his breathing was barely uneven, while Childe himself was a shaking, moaning mess. It didn't make sense, he was younger than Zhongli, so why was his body struggling to catch up?
“How... Ah... How are... Aah... How are you doing that?” He asked him in between moans.
Zhongli tilted his head to the side, obviously confused, and somewhat slowed down his thrusts, allowing Childe to regain some clarity of mind and speech.
“What do you mean?”
Childe couldn't believe his ears. How could he sound so... So genuine? He was fucking him again after already coming twice and not taking a single break, as if refractory periods were nothing but a myth, and on top of that, he failed to see what was strange about the situation?
“How are you still going at it?”
“Do you wish me to stop?” Zhongli inquired, concern lacing into his voice. “If it is too much, just tell me, and...”
“What? No!”
He shook his head and sunk back onto Zhongli's cock, hoping his actions would be better than his words at conveying how much he wanted this. He could take this, and he wouldn't let his lover think otherwise. Maybe he was biting off more than he could chew, but this was a challenge he refused to back up from, despite the protests of his body. Desire burned in Zhongli's golden stare. His eyes turned a shade darker when Childe wrapped his arms around his neck, then started riding him with enthusiasm, all while biting his lower lip to contain small cries as his body molded once more to the shape of his cock.
Slowly, the sensation of too much faded, replaced by pleasure as Childe felt himself become hard again. He lifted himself off Zhongli's cock and lowered himself back into it, again and again and again, until his partner lost patience and grabbed his hips to set his own fast, unforgiving pace.
“Yes! Give me more, please!” Childe begged him.
This was what he wanted: to be shattered and then put back together, to experience pleasure he would barely be able to recover from. And Zhongli was more than happy to give him that and more, hilting himself all the way inside Childe time and time again, until they both fell prey to another orgasm. Their bodies tensed in synch, but while Childe went pliant in his arms, utterly spent, Zhongli showed no such signs of exhaustion.
On the contrary, he still kept thrusting into the Harbinger's limp body, even after pumping more cum into him than what should have been humanly possible. Childe whimpered at the overwhelming feeling. He dug his nails into Zhongli's back, needing to anchor himself to something, anything. This went far beyond anything he had ever experienced. No one had ever reduced him to... to... He didn't even have a word for it.
It was almost unbearable. Each of Zhongli's thrusts left his body burning, the stinging so sharp tears started welling up in his eyes, but at the same time, it felt intoxicating. Some part of Childe wanted to plead him to please stop, it's too much, but he also ached to see how much he could take before his resolve would break, how long he would manage to endure it. The adventurous part of him won the battle and so he gritted his teeth, welcoming that heavenly torture.
He was so far gone that when a faint, barely visible, golden glow, shaped like a multitude of scales, appeared over Zhongli's skin, Childe didn't make much of it, deliriously assuming that he was being fucked so good he was hallucinating. Then it hit him.
Zhongli's endless stamina, his strange behavior, the countless scars on his body... Suddenly, it all made sense.
Celestia may have mercy on him, he was fucking a god. No, scratch that, he was fucking the god whose gnosis he was supposed to steal, the Archon Geo, Morax himself, and nothing in his life had ever felt more perfect.
He'd never been closer to completing his mission. He would just have to reach for the gnosis, to rip it out of Zhongli's chest. This lost in lust, his lover would never expect it. But he couldn't get himself to do it, and his weakened state had little to do with it.
It was too late. Childe would never be able to hurt Zhongli, now that he'd fallen in love with him.
There it was, that realization he'd tried so hard to postpone. And of course, he was coming to that conclusion at the worst moment, while being impaled on Zhongli's cock. How romantic. The absurdity of the situation made him want to laugh, and he probably would have, had he been able to emit any other sound than broken little moans of pleasure.
He idly wondered how long the Archon could keep this up without tiring himself out. Days? Even more? Would there even be an end to his godly stamina? Childe silently cursed his mortal body for being too weak to let him find out. A shiver of arousal ran through him as he imagined himself pinned down under the god for hours on end, unable to do anything but scream his name.
Zhongli chose that moment to finally wrap his hand around his neglected cock, stroking it to full hardness. Childe's mind went blank as he thrust up his hips in instinctive response, mindlessly chasing his pleasure. Zhongli's touch was too much and not enough all at once. Childe wasn't even sure if he would be able to come a third time. However, the Archon left his body little choice. He kept pounding into him and caressing his length until he wrenched one last orgasm out of him.
Childe blacked out for a few seconds, every single muscle in his body seizing up under the unimaginable pleasure. He almost came dry; only a few beads of cum dribbled down the head of his cock and onto Zhongli's long fingers. When he finally came back to himself, he was laying on the soft sheets, with Zhongli looking down at him worriedly.
“Are you okay? Did I go too far? I am sorry, I didn't realize...”
Of course, he didn't realize how far he was pushing him. Not when his Archon body didn't obey the same limitations as humans'. And to be fair, Childe hadn't exactly been complaining about how he was treating him either. The reckless, competitive part of him even wondered whether or not his lover would be able to make him come a fourth time, if he tried to. Regardless, he smiled at how much Zhongli obviously cared. It was kind of cute.
“Don't worry, you were perfect,” He reassured him, then he added in a teasing, mischievous tone: “You made it so good it felt like I was being honored by the Archon Geo himself.”
It took Childe all of his force of will not to chuckle when the color drained from Zhongli's face at his remark. However, he kept pretending to still be oblivious to his real nature. Let it be a small revenge for how Zhongli had concealed his true identity from him, or at the very least, had tried to. They would have that conversation later, when his body wouldn't feel like putty. For now, all he wanted was to clean up and cuddle with Zhongli. There would be plenty of time to think about the consequences of his actions come morning.
Not even half an hour later, he was slowly falling asleep curled up against Zhongli, with one hand resting on his chest, maybe right over his gnosis, for all he knew. It still astonished Childe that the Archon would let him, a Fatui, get so close. It filled his chest with a warmth he'd never experienced before. As he closed his eyes, an unwavering certitude carved its way into his thoughts:
No matter what it would cost him, he would not break that trust.
