Work Text:
Aether sits at his desk in the mansion of his teapot abode, pouring over reports he'd received from Jean regarding Abyss activity around Mondstadt.
When he offered to take some of her workload, he hadn't realised it would be quite this much. Stacks of papers pile high on both sides of the desk, and between them, he's flicking through the latest he plucked from the pile, nearly pulling his hair in frustration from the lack of actual important information contained within them. Honestly, how the Knights write so much about so little is a mystery.
Though, it's not all bad.
At his feet, tucked under the desk, Xiao kneels obediently, hands clutched around Aether's legs, slicked lips wrapped around his cock.
His eyes are closed and he makes no moves to suck Aether off. Only sits and keeps him in the delicious warmth of his mouth. He's been down there for a while now, letting out pleased hums sometimes but otherwise kneeling quietly, enjoying the safe, enveloping darkness of being under the desk and trapped by Aether's body.
Periodically, Aether reaches under the table to stroke through his hair to make sure he's alright. Xiao arches up into his touch like a cat, and moans lowly around Aether's cock when nails press lightly into the back of his neck. The vibrations make the traveller jolt, forcing more of himself down Xiao's throat, causing the yaksha to choke before steadying his breath and easing the rest of the length into his mouth.
Fuck. Aether tilts his head back on the chair, willing his hips to stay still. The paperwork can wait.
He pushes a hand through Xiao's silky hair, gathering a handful and pulling his head back. Half of Aether's cock slips out of his mouth with a wet sound, as saliva trickles down the side of Xiao's mouth. His eyes are blank, slowly blinking up at Aether as he seems to regain sense of where he is.
Aether pants, mounting arousal building rapidly and washing over him. He gives Xiao's head another sharp tug, eliciting a moan. "Can you take me, Xiao?"
Xiao swirls his tongue around the tip, nodding his agreement.
Aether wastes no time. He pushes his chair back, dragging Xiao from under the desk without separating them, and rising to stand. "Remember, tap my thigh if you can't take it, okay?"
Xiao nods again. He swallows Aether's cock all the way up to the hilt, spreading his fingers on the floor and arching his back for stability. Aether looks down at him, admiring the curve of his back and sighing as he slips deep into Xiao's throat. With a hand fisted in his hair, he holds him still as he slides nearly all the way out of his mouth, before slamming his way back in.
He sets up a fast, brutal pace, unable to do anything against the waves of pleasure that roll over his body as his cock plunges into that wet cavern over and over. The build-up of pre-cum and saliva produce the most filthy noises. Xiao chokes at a few particularly rough thrusts, but otherwise keeps his mouth open and holds his body still.
Aether continues plunging into his mouth until the pleasure reaches its peak. He finishes with a grunt, his release pooling at the corners of Xiao's lips, making a horrible mess of him. Aether doesn't stop until he's soft, panting heavily when he finally pulls out of Xiao's mouth and tucks himself away, a pleasurable haze settling over his body.
The sight of Xiao beneath him makes him horny all over again.
The yaksha is panting, chest heaving, as his sharp golden eyes drink in the sight of Aether, pleased and sated, above him. His cheeks are wet with tears, eyes glossy, and a mix of pre-cum and saliva spills down one side of his mouth. Without breaking eye contact, he scoops it off with a finger and sucks it off.
Aether shivers. "Fuck."

He'd been meaning to meet Zhongli soon, having opted for attempting to do some work first. The man needed Aether's help getting Hu Tao out of trouble with the Milileth, something he couldn't afford to be late for.
He stands outside the mansion, Tubby nowhere to be seen, willing his erection away. Upon realising the time, he'd helped Xiao up, kissed his forehead as apology, and dashed out the door. Only now does he realise the glaring problem in his pants.
"You can always claim it's where you store your abode," comes an amused, slightly hoarse voice behind him.
Aether turns to find Xiao leaning against the mansion's open door with his arms folded and gaze glued pointedly to the traveller's current issue.
Aether pulls his scarf around in an attempt to cover himself. "Do you think anyone will notice if I start wearing my cape backwards?"
Xiao huffs a little laugh that sets off fireworks in Aether's chest. "It will certainly look suspicious."
"Great. I want you to know I blame you for this."
Xiao raises an eyebrow before stalking forward so he's centimetres away from Aether. He trails a hand from his chest all the way down until he reaches the waistband of Aether's pants. "Perhaps I should take some responsibility, then."
Aether moans his agreement when slim fingers wrap around his length. His hands go to Xiao's waist, where he squeezes in time with the languid pace of the yaksha's hand.
Xiao presses their bodies closer. "Did I not tell you to use me as you see fit? Whether it be killing or… this. You have done so much for the people of Liyue, myself included." His lips hover over Aether's ear. "Take your reward."
Aether rips Xiao's hand from his pants before spinning him around and slamming him into one of the columns. Xiao gasps as his chest is pressed into the wood and his hips are pulled outward, the traveller bending him into an delicious arch. Aether pulls the other's pants to his knees, cock twitching when he sees that Xiao is wearing nothing underneath.
"Do you have any lube?" He manages to get out amidst his lustful haze.
Xiao presses the side of his head into the column to look back at him. "There is no need. I have already prepared myself."
Aether wants to ask when but he's already running late, and Xiao's earlier words are still swirling in his mind. Take your reward.
He lowers his pants just enough for his cock to slip out, before he pushes himself into Xiao, one hand on the yaksha's hip, the other guiding his cock inside. They both groan when Aether gets about halfway in, and he shifts so both his hands are pressing bruises onto Xiao's hips. He bottoms out with a moan but collects himself quickly. He's really running late now.
He thrusts into Xiao hard, causing the yaksha to gasp. He doesn't opt for how he usually fucks him - slow and steady, shallow thrusts mixing with long, hard ones. He plants his feet and pounds the body before him in quick jerks of his hips. Xiao whimpers as his hips are continuously pulled back, but there's no way he could be getting much pleasure from this.
It's a selfish fuck. Aether doing as instructed and using Xiao's body for his own pleasure.
Aether keeps up the rapid pace, hips slamming into the plushness of Xiao's ass. He throws his head back, lost in the feeling of his cock gliding through Xiao's walls, hammering into him at a pace that jerks Xiao's body back and forth. His messy hair sways as he's pounded, and he lets out little grunts and moans that serve only to drive Aether on.
Aether's release comes unexpectedly. He chokes on a moan, slipping and thrusting into Xiao, wet and sloppy as he doesn't halt his pace through it. The sound of his cum being slapped into the yaksha's hole is obscene. When he finally finishes, his release dribbles from Xiao's entrance, leaking out as he pulls his cock out.
Xiao moans softly beneath him, straightening up and fixing his clothes. He turns, glancing down at the traveller's now- normal appearance. "You should be on your way," he says, breathing a little harder than usual. "You were late around ten minutes ago."
"Oh - right!"
Aether presses a messy kiss onto Xiao's cheek before whirling away and practically leaping from the mansion steps.
-
Later that night, he finds Xiao in the hot springs, at the highest part of the mountain.
The yaksha is submerged from the chest down, eyes closed, steam billowing around him. Gold pierces through darkness when he meets Aether's eye, and a hand slips out of the water to beckon him in. Aether is not one dumb enough to refuse an adeptus. He wastes no time throwing off his clothes and entering with a splash.
It'd been a long day. Commissions and paperwork and convincing the Milileth Hu Tao wasn't trying to kill people while Zhongli and Paimon rambled on either side of him.
Sliding into Xiao's embrace is too easy. Lithe arms curl around his neck, fingers undo his braid and card through messy, tangled strands. Xiao straddles his lap, doubling the heat already risen to Aether's cheeks, and tuts at him.
"You should take better care of your hair. It's beautiful."
Aether clutches Xiao close. Hides his flustered expression in the crook of his neck. "Maybe I'm just irritating you enough that you'll wash it for me."
Xiao hums, then his fingers get caught in a particularly tough knot. "It is working. Where is the comb?"
They end up with Xiao perched on the edge of the rock, submerged only knee-down, while Aether sits between his legs and leans back as Xiao's strong, gentle fingers work through his hair. The cool air on his flushed face is nearly as pleasant as the feeling of Xiao taking care of him. He thinks he could get used to life in Teyvat like this - when he has Xiao to come home to.
Aether leans against one slim, pretty leg as Xiao finishes, tracing patterns into the side of his knee. He hears Xiao gasp when he locks his lips there, and starts sucking lazy kisses up his thighs.
Aether loves Xiao's thighs - then again, he loves every part of Xiao.
He turns in his hold to kiss at his hips, and then up his sternum when Xiao moans and leans back to give him access to his torso, comb forgotten somewhere on the rock-face. Aether lavishes all of him in affection, returns all that Xiao gives him until he has him splayed out, panting and hot beneath him.
With his focus still drawn to Xiao's thighs, he presses them together and draws them up to hold over his shoulder, marvelling at how flexible and pliant Xiao is. Pressing flush against him, he slips his rapidly hardening cock in the small crevice created between Xiao's thighs.
"Oh!" Xiao's moan is soft, surprised, and he follows it with more when Aether sets up a languid, lazy pace.
The water eases the slide of their bodies, as does the pre-cum dripping madly from Aether's cock. He sees Xiao curl his hands into the stone floor beneath them, before raising one as if he wants to touch himself, but making no other moves to do so.
Aether clutches one hand to Xiao's hip to steady him against his thrusts, the other coming to curl and squeeze at Xiao's thigh.
"Touch yourself," he says, strained against the pit of arousal opening within him. "I know you want to."
Xiao gasps when he takes himself in hand and matches the increasing pace of Aether's hips. Their wet skin slaps together, nearly a painful sting, reminding Aether that they'll dry eventually, and then it will start to hurt.
So he speeds up, chasing his orgasm, delighting in the helpless moans of the adeptus beneath him as their cocks brush together. As he's taken in the most impersonal manner, used like a toy.
Aether knows - has always known - that Xiao loves it.
It's obvious from the uncontrollable moans and sighs falling from his lips, even though he can't possibly be getting as much pleasure as Aether is from this. It's obvious in the arch of his back as he finds his release from being used like a sextoy. The hungry way he watches Aether as his hips stutter and he has to bite into Xiao's thigh to stifle his own moans as he follows, finishing over Xiao's abdomen, coating him in even more fluid.
He looks incredibly satisfied, sitting up and shoving them both back into the water to clean up again.
"How redundant…"
Aether laughs, shifting so he leans back into Xiao's chest, and the yaksha's arms come around his neck, resting over his chest.
A hand cards through his bangs. "Do you feel any better?"
Aether yawns. "So much better that I'm ready to do it all over again tomorrow."
"Good."
Xiao's long passed the stage of insisting Aether rest all the time, and stop doing so much for everyone. Besides, it's not as if he can talk. They've both accepted each other's ridiculous work schedules, and seek to help each other in moments like this instead.
At that thought, Aether suddenly feels the need to ask, "Hey, Xiao?" A hum in response, that vibrates his chest. "You know you can ask me if you want anything, right?"
"I told you I am content to submit to your desires. I do not require anything else."
"What if I want to give you something else?" At Xiao's silence, he adds, "Anything. Everything. I'll-"
A hand cups his mouth. He looks up to see redness creep over Xiao's nose, more glaring than the flush from the hot water. "It is unnecessary, but I know how insistent you can be…" He grumbles, "Fine. Let me think."
The hand on his mouth falls and Aether waits patiently while Xiao thinks.
It doesn't take long for him to cough, drawing Aether's attention, who turns around to face him, grinning in delight when he notices Xiao struggling to meet his gaze.
"Yes? What does my stubborn yaksha want me to do to him?"
Xiao scoffs a little at the nickname, and moves forward so he can press a light kiss to Aether's cheek and speak into the base of his neck, hiding his face while simultaneously making Aether fluster at the sudden gentle affections.
"I want you to take me apart." A hot wave of arousal threatens to drown Aether at his words. "Until I can no longer form words. Until I have no choice… but to be yours."
Aether moves so fast he surprises himself. Xiao barely restrains a yelp and clutches his arms around Aether's neck as he's lifted into the air in a princess carry.
Aether grins down at him. "Your wish is my command."
