Chapter Text

Childe sometimes goes to the black market. Not always because he has a job to do there, but just because he wants to look at the weird invention of the week.

And apparently this week, it’s an odd fleshlight.

He has bought one out of curiosity, but now that he’s back in his quarters, he inspects it carefully.

Of course the instructions were vague.

“Keep the one you desire in mind, and enjoy!”

Childe guesses this toy is just imbued with elemental energy to replicate the feeling of a person’s hole.

Nothing exceptional per se, those have been around for a while. But in his current situation it could be useful.

After all, he’s been stuck on boats for months now, traveling between Inazuma and Snezhnaya, rarely stopping by Liyue.

So he misses Zhongli.

Suddenly, the object in his hand lights up, and geo sigils appear on it. It surprises Childe, because he would have thought it would have been hydro sigils instead? Given that it’s his elemental power powering it up.

Curious now, he tests it out, pushing one finger in, just up to the first knuckle.

And to his surprise, it actually clenches around his digit, quite realistically at that. He could be fooled that it’s a person if he closes his eyes.

When he removes his finger, and the “muscles” tense as he pulls out.

“Odd. It’s reacting like a real hole.”

Childe ponders about it for a moment.
But he’s alone in his cabin, a long way until the next stop, and no one will bother him unless the boat gets attacked by a sea monster.

So he might as well indulge, right?

He grabs the toy again, and this time pushes his entire finger inside of it.

It feels warm, and with a little hydro manipulation, wet too.

Slowly, he explores the inside of the fleshlight, adding another finger to prob a little deeper.

And to his surprise, he finds a spot that makes the entire toy throb and clench. He keeps rubbing it, pressing around it, amazed how it feels somewhat real.

It does remind him of Zhongli, so maybe the seller wasn’t lying after all.

He can feel the tightness in his pants, so he takes them off before he makes a mess. When his hand brushes against his erection and he hisses.

Immediately, he removes his glove and wraps his free hand around his shaft.

Then he brings the toy to his mouth, following an impulse.

He wants to know how it feels on his tongue.

And, well, it needs lube, after all.

So Childe begins to work his way inside the toy, wondering how the object is going to replicate the clenching of a real body.

His mind goes to Zhongli again. The man would never let him do that to him.

That’s why he can’t help himself, imagining how his Xiansheng would sit on his face and let him shove his tongue inside of his tight hole, and make him come over and over again.

And maybe he loses himself in his fantasy, as drool starts spilling from his mouth while he pushes his tongue deeper and deeper.

The toy seems to react to this, even more than with his fingers.

Childe loves it, imagines Zhongli riding his face without any shame and taking everything Childe is giving him. He would end up a whimpering mess, and all the more beautiful to his eyes. He wishes he could make it happen.

Just the idea makes him jerk his hand on his cock faster.

When they toy is wet enough to his liking, he takes it away from his mouth and lowers it towards his crotch, rubbing the tip of his shaft on the entrance, feeling it tightens as he spreads the makeshift lube on it.

And then, slowly, he pushes it inside, revelling in the tightness around him, the way the toy clenches on his cock.

He moves while keeping a slow pace, taking his time. There is no rush after all.

He wonders if he can fit entirely though, because the sleeve appears to be just a little bit short.

But to his surprise, the object seems to extend internally, somehow. Whatever magic that thing has, it definitely works.

Because the toy eventually swallows his entire length, and Childe has to pause for a second so he can breathe.

It feels too good, too real and once again he can’t believe it’s just a fleshlight and not his boyfriend’s ass.

He starts moving, carefully at first, testing out what this toy can do. The mix of spit and pre-cum does help with the motions, even if it still feels a bit dry by moments. Then he picks up the pace, holding the toy tightly between his hands, pushing it down on his dick hard, hitting that spot that made the whole thing clench and throb earlier.

He fucks into, thrusting his hips and hissing between his clenched teeth, not holding back. His arms slap a few times against his thighs, in his lust he can’t bring himself to slow down anymore and just wants to feel more.

And at this pace, he doesn’t last long. The weeks of frustration, abstinence and yearning unwind and snap at his body like a bow’s string and he comes, his climax hitting him hard and his seed spilling inside the toy.

He slumps back onto his bed, sighing in satisfaction and relief. While he’s a bit sad he didn’t last long, at least he doesn’t feel as frustrated.

With a wince, he realizes he’s going to have to clean the sleeve before it dries up. But when he pulls out, there’s just… nothing.

“Does it clean itself?” he wonders to himself, turning it around to inspect it.

Looking at it closely, he also notices that the inside of the toy is still clenching, twitching nervously almost.

“Just like Xiansheng,” he chuckles, remembering how Zhongli tends to get extremely sensitive after sex, a subtle trembling going through his entire body.

Childe nudges his finger on the entrance, once again impressed by the object’s reactions, almost too real to be just a toy.

At least it’s worth the money, he thinks with satisfaction.

The rest of his trip is uneventful, meaning that he has a lot of time to experiment.

It always seems to react to any touch, to anything he does to it, and Childe has enjoyed it to his fullest.

Sometimes he goes to his cabin in the middle of the day and has a quickie with it before returning on deck to watch over the crew. Some days he would have an edging session, keeping himself from cuming for hours, loving the way the toy is responding to it because it remains tight around his cock.

Another day, he uses his Hydro vision to make water tentacles, and watches as they fill up the toy, writhing and undulating inside, even dragging out the cum he spilled earlier. And when he enters the toy, it’s clenching so hard that he comes right away. Of course he gets back to it right after.

He even tries the Riptide on it, and it’s one of his best ideas. It amplifies everything, the inside of the toy reacting strongly to it, making it even better.

Childe uses it at any hour of the day, anytime he feels like it, which is very often. Morning, middle of the day, evening, and even in the middle of the night.
And it never gets old, always better.

Really, he wishes he could fuck Zhongli as hard as he has this poor toy, but sadly he can’t do that yet. They have barely started getting intimate, he doesn’t want to scare his lover with his crazy sex drive.

But he does wonder if he should buy one for Zhongli… but it would probably be a bad idea, knowing how the consultant was still shy and embarrassed about that topic.

It might earn him a meteor in the face. So best avoid it… for now.

When Childe finally arrives at Liyue Harbor, he’s delighted to see Zhongli waiting for him on the pier, his figure recognizable even at a distance.

Childe happily jumps from the boat before it even finishes docking, rushing to see his boyfriend.

However, he notices something on the consultant’s face.

And the closer he gets, the colder the wind on his back gets.

Zhongli is upset. Annoyed. Embarrassed.

Which for whatever reason has Childe panicking, thinking he did something bad.

Before he can run away however, the Liyuen (former) Archon walks straight to the Harbinger and grabs him by the collar.

“You. Have. A lot. Of explaining. To do.” Zhongli hisses between clenched teeth.

“Uuuhh???? Wh-What do you mean????”

Having a closer look on Zhongli’s face, Childe can decipher his expression a little bit better.

Zhongli’s face is flushed. But it looks like “anger hiding embarrassment” flushed.

Which is definitely odd coming from him.

“What? What happened?” Childe asks again, dumbfounded.

Zhongli huffs, lets go of Childe’s jacket with a frown.

“Do you not know?”

“No???”

Zhongli sighs, obviously annoyed. He crosses his arms on his chest, obviously trying to keep his composure.

“Then should I tell you what your latest acquisition really does?”

And. The way Zhongli stares daggers at him, his tense posture, the light blush on his face. Finally make Childe’s brain connect the dots.

“Oh. Oh. So it was you after all.”

Chapter Text

On a quiet day, Zhongli has decided to sit in the teahouse for a moment. There is very little to do at the Funeral Parlor, and Director Hu has been running around Wuwang Hill to look for potential clients (if she wasn’t making them herself). So he has the rest of his day to himself.

His plans have been to enjoy the peace while it lasted.

So when he feels a wave of elemental energy hitting his… backside, he immediately tenses up, glancing around to find any threats, but there doesn’t seem to be anything unusual.

It’s definitely not his imagination, but he doesn’t know where it comes from.

And then, all of a sudden, he feels something… getting inside.

Zhongli chokes on the tea and almost cracks the cup at the same time.

It’s a ghostly sensation, not a material object, but obviously materialised through elemental energy somehow.

The thing gets a little deeper, probing and rubbing inside curiously. It doesn’t last long, however, and it retreats without a trace, the invading sensation fading suddenly.

The consultant has no idea what has just happened, but he has the inkling that it’s not going to stop there. No matter what it is, it doesn’t seem like the culprit is in the vicinity, and thus, he has no way of stopping them.

However, he knows staying in the teahouse would be a mistake.
So he puts mora on the table, and leaves.

He is not quick enough, because the moment he walks out of the building, the probing sensation comes back. And this time, there is also a cold feeling to it, like chill water following inside.

It even goes deeper, and Zhongli has to hold back a moan when it brushes against a sensitive spot.

He curses internally, and hurries away to his apartment.

Thankfully he isn’t that far, the teahouse barely two streets away from his home.

Unfortunately, he feels the thing inside of him getting thicker, stretching him uncomfortably. It keeps moving around, touching and rubbing, getting bolder and bolder by the minute.

When he stumbles on the threshold of his house, he manages to get the door shut before something else replaces the long object from before.

And this time he barely holds back a shocked moan.

It feels different, less… rigid and more slimy. It rubs against his hole, as if playing with the muscle there, and slowly pushing through, getting past the entrance.

Zhongli can’t hold back his moan this time, and he almost trips in the hallway, barely catching himself on the wall.

He starts feeling too hot, his clothes feel suffocating when he was feeling perfectly fine earlier. Taking off his coat, he carelessly throws it on the buffet by the entrance corridor. He can’t bring himself to care at the moment.

The thing inside just keeps moving, slithering its way deeper, and while it’s not as deep as the previous one, it definitely feels different.

A lot wetter too. Somehow.

Zhongli considers his options while his mind is not drowned yet. A talisman against evil would do the trick if it is an evil spirit, which he doubts. Old gods are out of the question entirely.

Which only leaves the possibility of someone that can bypass his protections.

And the only one he can think of is Childe.

But how? He’s not even in Liyue, he’s on a boat, going who-knows-where, doing his work as Harbinger.

It doesn’t make anything sense.

A particularly sensitive spot shoots bolts of electricity through his entire body when the thing brushes past it, around it, as if playing with him.

A tongue, Zhongli realizes. It’s… a tongue.

The late realisation doesn’t help him much however.

Because that tongue is making it more and more difficult to focus on any rational thought. It is moving

slowly, excruciatingly so even. Whoever is doing this to him seems to have fun, apparently.

(He’s starting to suspect it’s Childe more and more but he’s not fully certain yet)

And as much Zhongli is upset by it, his body is reacting to it.

He has never done anything like this before. Never dared to ask Childe because he doesn’t know what to expect from his boyfriend, and because he’s horribly embarrassed by the topic.

Now he can’t even escape it.

It keeps moving, rubbing against all his sensitive spots as if it knows exactly where they are. Every movement pushes him closer and closer to that edge, and he stumbles onto the couch, falling into the cushions when his legs refuse to support him anymore.

He tries to remove some of his clothes, barely manages to pull off his tie and take off his light jacket, leaving his shirt and pants open left on him.

The brain fog becomes unbearable, being kept on edge for so long without any kind of relief was torture. He feels the arousal clouding his mind, already clawing at his crotch for release. No amount of writhing and whimpering helped, no matter how he sits down it doesn’t get deeper or moving at a different angle so he can finally get the friction he needs.

And when he feels the invading tongue retreats, he knows that this isn’t over.
Not when a much larger object starts probing against his entrance. Rubbing against the muscle slowly, as if toying with him.
And then comes the push. It’s slow, careful, tentative, but not hesitant. It’s stretching him almost uncomfortably, but somehow it doesn’t hurt.
It reminds him of his first time having sex with a human body. Childe took care of preparing him thoroughly back then, much to Zhongli’s embarrassment. But it made his experience all the better.
Right now, he can’t help but feel the same way that he did back then.
Not knowing what to do, getting overwhelmed by sensations he’s not familiar with, and blind at what is about to happen.

As the thing gets deeper and deeper inside, he moans and whimpers, biting his fingers in a vain attempt to remain quiet. And he already knows what it is.
The fact it feels exactly like Childe doesn’t help, making him wonder what his stupid boyfriend got himself into.

When it finally stops moving, the entire length is sitting inside of him, hitting all the right spots and making Zhongli clench tightly around it.
It doesn’t move right away, as if waiting for something.

But when it does, it remains slow, painfully so. It’s not really smooth, for the lack of lube, however it doesn’t stop the cock from moving.

Of course, each motion rubbing on his sensitive spots makes him tremble and jolt in response, his body slowly adapting to it.

Even when the pace gets gradually faster, and the movements harder, Zhongli can’t help but wrap a hand around his own length and jerks it clumsily.

The cock fucks hard into him, pounding him into the couch, pinned down by the invisible pressure. He starts seeing stars behind his eyes, but he can’t stop it. He braces himself on the cushions, holding onto them so tightly that he might rip off the fabric.

It doesn’t last as long as he has expected, however.

One last thrust, and then Zhongli can feel the warm liquid spilling inside of him.

That’s when he knows for sure.
It’s Childe’s essence.

And just like that, his climax hits him full force, soiling his hand with his semen.

The presence retreats from his body, and suddenly all the invisible strings holding him together snap. He falls onto the couch, panting, his mind clouded by the high and the release.

But now he knows for sure.

When he comes back to his senses, he realises the sticky mess between his legs.

“I am going to kill him,” Zhongli sighs with annoyance, letting out a sigh.

Well, for now he has to clean himself.

And prepare for the worse.

For the next few weeks, Zhongli goes about his routine with a constant frown plastered on his face. He knows better than to expect Childe to be reasonable.

And of course, he is right about that.

Sometimes it’s quick and he has the time to deal with the aftermath; other times, he can’t escape Hu Tao long enough to clean the mess, and so he sits uncomfortably for the rest of the day, until he can finally go home.

Too often for his sanity, Childe (because now he knows for certain he is the culprit) will keep himself from climaxing, all the while Zhongli will be reduced to a whimpering mess on his bed, overstimulated and overwhelmed.

The worst one, in Zhongli’s opinion, is when several “tentacles” formed by Hydro manipulation, stuffed him full for the entire day, moving inside and pushing all of his buttons at any given time. He barely manages to keep himself standing, and eventually has to excuse himself so he can retreat back to his house and collapse on the ground. It didn’t help that Childe fucked “him” earlier, and the tentacles kept playing with the semen Zhongli hasn’t had the time to clean by the time they appeared. And when Childe enters him, pushing against the tentacles, Zhongli is pretty sure his screams are loud enough to be heard in the Harbor.

When the Riptide appears on his stomach in the middle of his walk, Zhongli curses silently and rushes back home. He doesn’t even want to risk being outside, despite the fact he has grown (somewhat) used to these intrusions. The Riptide is too overwhelming for him. It makes him oversensitive every time it shatters, and each climax is harder and violent than the last. He even faints one day because of how overwhelmed it makes him.

And yet, he can’t bring himself to hate it.

Although he is definitely mad at Childe for this.

Days after days, regardless of time and place, Zhongli endures the invisible presence fucking him relentlessly, and to his shame, a part of him expects it. Wants it.

He even catches himself fantasising of Childe doing this to him directly.

His own desires are an unexpected side of this predicament. Something he hasn’t thought of, while he was drowned in Childe’s attention and lust.

And maybe that would be a question he’d need to address with his boyfriend, once he’s back.

However he does plan to smash him with a pillar first.

The meteor would be too obvious.

When he hears about the Snehznayan boat arriving, Zhongli rushes to the Harbor. He can’t contain the relief to see Childe after all this time apart.

Even if he is still mad at him.

And it doesn’t take long for Childe to notice him, waiting on the pier.

While he had been smiling at first, concern slowly replaced it when he saw Zhongli’s expression.

Of course it doesn’t take long to clear up the situation, but it doesn’t make it less embarrassing for them both.

“How did you even know it was me?”

“I am familiar enough with your essence that I can recognise it.”

“But how… oh. Oooooooh I see. Uh. Sorry?”

“Hmpf.”

“I am really sorry, Xiansheng. From the bottom of my heart sorry.”

Zhongli keeps pouting, avoiding his lover’s eyes. The embarrassment is too much to bear at the moment. It’s one thing to know that it was Childe all this time, it’s another to come to the realisation that Childe did all this thinking of him.

“I cannot believe you used one of those. Have your hormones fried your brain?”

“I was frustrated. And I missed you. Also how did you know what it was before I even said anything?”

He can see the curious look that Childe gives him from the corner of his vision, and he feels the blood rushing to his face.

“Those have been around for a long time. The work of an adeptus curious about humans’... mating habits.”

“Really????? I never would have thought the mighty adepti had those kinds of interests. Funny though.”

“You better get rid of this thing, Childe.”

“Oooooow really? I paid a lot of mora for it!”

Zhongli huffs, and looks away, annoyed. Childe walks in closer, locks their hands together.

“Or… maybe you want me to do this to you instead?” he whispers, a mischievous grin on his face.

And of course, he expects Zhongli to deny and reject the idea. Really, he just wants to tease him. Because he loves seeing the consultant blush.

“Hmmm. Although not everyday.”

Childe freezes at the words, staring at Zhongli with wide open eyes.

“W-what?”

But Zhongli doesn’t repeat himself. Instead, he pulls on Childe’s hand to get him to move, leading him on the way to Wanmin Restaurant.

“Xiangling tried a new recipe while you were away, she asked me to bring you over as soon as you were back. And there’s a new play I wanted to watch with you…”

Zhongli’s voice slowly fades into the background while Childe still stares at him without a word.

Crushed by the metaphorical meteor made of Zhongli’s words.
