#luckae fic thread for (attempted) horny july bingo!
prompt: clothing kink + [redacted] + [redacted]

.

What greets him upon entering Angel's Share, minutes before closing, is the sound of a glass breaking.

"My, my," Kaeya drawls as he seats himself straight across Diluc, eyeing the glass shards scattered on the counter separating them with barely concealed amusement. "Do you loathe me *that* badly?"

"Sir Kaeya." Diluc is gritting his teeth so tightly that his lower jaw twitches. "What are you *wearing*?"

"Oh, this?" He gestures to the high collar of his outfit, trailing his gloved fingers down the length of its blue tie

until they rest on the dark leather belt cinched tightly *just* under his bust. "Why, it's a Captain's uniform."

Diluc's eyes narrow; the heat of his gaze burns. "It's not yours."

"No, it's not," Kaeya affects a bright, bubbly laugh, his long lashes sweeping against the sharp jut of his cheekbone as he pretends not to notice the way Diluc's pupils dilate until what is left of his iris are twin rings of fire.

It is so terribly tempting to give in to the intensity of their flames, but no—Kaeya has a game to play, and there is no fun in quitting it this soon. He deserves a little bit of fun after everything he had to deal with today, doesn't he?

So he smiles, one hand reaching down to smooth the semi opaque fabric of his uniform—a seemingly meaningless gesture, considering how tight the fabric is stretched across his torso.

He makes a performance out of it, nonetheless, just because he can; rests his finger around the golden emblem framing his navel and watches in delight the delicate movement of Diluc's throat as he swallows. "It's Eula's," he says, as if it's not already obvious.

"And why—" Diluc has taken to gripping the edge of the bar counter, as if to steady himself. "—are you wearing Captain Eula's uniform?"

Kaeya idly twirls a strand of his hair, propping his head on one hand. His hairpin bobs with the movement.

"It's a funny story, really—I had three meetings back to back, all out of town, but apparently the maids seemed to have mistaken *my* overnight bag as Eula's, and packed her outfit instead of mine."

"So you decided to just, what, attend your meetings in—that?"

"The dress code asked for service dress uniform—surely you cannot expect me to breach protocols and show up in something else?" He raises an eyebrow, his lips curled in a gleeful pantomime of disbelief.

"Besides, I don't think anyone minded. The meetings all went *very* smoothly—much more so than I thought they would be, in fact. I wonder why..."

The bar counter starts to splinter.

When Diluc looks at him, *really* looks at him—it is with a look that promises retribution. "I have a change of clothes, if you need it. Upstairs."

Oh.

*Oh*.

The game has barely begun, and Kaeya has won.

"Is that so," he all but purrs. "How benevolent of you, Master Diluc. I'll go now, then."

Diluc says nothing in return, but Kaeya does not need him to.

He can feel Diluc's eyes on him as he struts towards the stairs, the sharp heels of Eula's tall boots making his every step louder than it should be. They are not at all comfortable—Eula's shoe size is at least two size smaller than his own, and her being shorter than he is means

that her boots reach no further than his mid-thighs, leaving a considerable expanse of his thighs bare. He's pretty sure his feet are blistered, too, judging from the stinging pain.

Her bodysuit, however, fits him rather beautifully, the material stretchy enough to accommodate his broader shoulders. He needs to cinch the belt tighter Eula does, on account of his relative lack of *assets*, but he thinks

he makes it work, still—no, he *knows* he makes it work, if Diluc's heated silence if anything to go by.

Giddy with possibilities, he slips into the tiny room where Diluc sleeps when his, ah, nightly duties do not allow him to return to the winery before daybreak.

Sure enough, there is a small dresser there, pushed flush against one corner of the room, but Kaeya ignores it in favor of the neatly made bed.

Now all he has to do is wait.

(break for bedtime 🔥❄️)

this is my first attempt at writing non-whumpy NSFW so idk how this would go but let's see!!

Diluc does not slam the door shut behind him.

He is entirely too *noble* for that, which Kaeya finds absolutely endearing. But there is no mistaking the abyss-dark look in his eyes as he takes in the sight in front of him:

Kaeya, lounging with perfectly manufactured carelessness on the bed, his long legs folded on top of one another and his head propped on a stack of pillows as he looks at Diluc through half-lidded eye.

"Took you long enough," he says, even though they both know that barely five minutes has passed since Kaeya made his way upstairs. He stretches his legs—still clad in Eula's ridiculous boots, because he is nothing if not dedicated to his causes—and counts backward from five

the time it would take for Diluc's resolve to crack and shatter entirely as he makes his way to the bed, an eagle eyeing its willing prey.

Diluc pounces by the third count.

He's straddling Kaeya between his thighs, grasping both of Kaeya's wrists in one hand as he pins him to the bed with the all the strength of someone so thoroughly trained in claymore-wielding. Kaeya can feel the heat of his hands even through his gloves, and—

"Losing control over yourself already, Master Diluc? How unlike you," he teases as he tries to wriggle free out of Diluc's grasp, just to see if he could.

Just to rile Diluc up further, because it has been far too long since they both could spare any time for this—the crescendo of all their desires.

Diluc's response is a growl. "You—" he starts, his grip around Kaeya's wrists tightening. By the morning it will color his skin a deep shade of purple, a mark of ownership hidden under his his gloves—one of their little secrets.

Here's another one: that Diluc's teeth feel like heaven when he sinks them into the bare skin of Kaeya's shoulder, its pain translated into a pleasure so sharp that for a moment he forgets about the game they are playing and *moans*, loud enough for his voice to carry downstairs.

"Luc—" he gasps out as Diluc's tongue brushes against the mark he just made, its tenderness deceptive. He lets go of Kaeyas wrists, at last, to paw at the clasp of the bodysuit, and Kaeya realizes a second too late that Diluc does not unclasp it so much as breaking it altogether.

He throws its stiff leather collar across the room with the fervor he usually reserves for Abyss Mages, leaving Kaeya's neck bare for him to sink his teeth there, too.

"You'll need to, ah—pay to repair that, you know?" Kaeya says, even as he clutches the front of Diluc's shirt to pull him even closer, mark him even deeper. With movements made smooth from *experience* he unlaces the front of Diluc's pants, pulling down his underwear to trail

a finger up his hardening length until it rests on its sensitive head. He circles it in slow, lazy movements—just enough for Diluc to buck against his palm in a silent demand for *more*.

Kaeya thought Diluc would give in, just like that—but when Diluc pulls back, his eyes are gleaming like copper coins. His usual softness evaporates, and in its place is the most delectable kind of determination;

one that promises searing reminder of the price one has to pay for messing with the Diluc Ragnvindr.

"Then let's make those repair fees worthwhile, shall we?" Diluc replies, his smile full of edges, and rips the front of the uniform in one sharp move.

(break for sleep again 🔥❄️)

i fully intended this to be a drabble/ficlet but we're at, uh, 1.2k words and i haven't even touched the other kink(s) i want to write lmao im gonna go put my clown makeup now

Kaeya intends to complain about Diluc's casual disregard of other people's belongings, he really does—but the sound being ripped out of his throat is instead a long, high-pitched *keening* as Diluc latches on to one of his nipples and *bites*,

the pleasure-pain of it making his knees jerk where they are still trapped between Diluc's thighs.

"Luc—!" he manages, his voice far less dignified than he wants it to be, as Diluc's hand reaches to pinch his other nipple until it, too, pebbles under the ministration.

He has never realized how wonderfully *rough* Diluc's gloves are, until now; how *sensitive* his nipples can be as Diluc flicks and pinches and licks and sucks until Kaeya feels like he can come from that alone.

"I can almost see them through your outfit," Diluc says, licking his lower lips as he rolls the buds between his fingers, smiling darkly when it forces another undignified, near-breathless keen out of Kaeya's mouth.

"Did you enjoy it? Knowing that *everyone* can almost see them too? Did they—" he *pinches*, hard enough that Kaeya can feel the blunt edges of his nails even through the gloves, "—harden when you feel other people's eyes on you?"

"Are you, ah—" Kaeya has almost forgotten his hand on Diluc's length, but its hardness has now become impossible to ignore. He runs a finger over its slit, in a way he knows Diluc likes; wraps his gloved hand around its shaft and watches as Diluc gasps and stutters. "—jealous?"

A gentle squeeze, in place of an emphasis. A pressure against the sensitive underside of his cock; his frenulum, the reddened head on his cock. His reward is immediate: Diluc bucks into his hand so hard that he nearly collapses into his elbows as he moans with his eyes squeezed

shut, as if pleasure has temporarily blinded him.

"*Fuck*," he curses. "*Fuck,* Kaeya."

Kaeya drags him down, then; kisses him with the hunger that he reserves only for Diluc, for the small victory of feeling Diluc gasp into the kiss, hands pawing hopelessly at Kaeya's chest,

his waist, the swell of his ass. It is only when Kaeya feels his fingers brushing against his rim that he breaks the kiss to gaze up at Diluc's dilated pupils. "Lube—" he breathes out.

A contemplative look falls over Diluc's face for a moment before the curve of his smile turns sharp, *dangerous*. "Lube, huh?" he muses, rummaging through the bedside cabinet for a moment before he pulls out—

"Luc," Kaeya cannot help it—his own dick twitches in interest even as he stares at the bottle in Diluc's hand with mild alarm. "That's—?"

"This?" Diluc is taking his glove off with his teeth in one smooth, practiced movement, his eyes not leaving Kaeya's face.

"This is your only lube, for tonight."

"But that's—?"

"Not what you're expecting?" the bottle is opened with a pop before DIluc pours its content liberally over his fingers—its worryingly *red* content.

He pours its excess carelessly over Kaeya's chest, and *fuck*, already he can feel the way it heats up and tingles, enough to make him want to reach down to his pebbled nipples and—

"Don't touch them."

Diluc does not raise his voice. Yet the steel in his voice stops Kaeya, regardless, in spite of himself. He whines, instead, long and needy, because the heat is too much and not enough, not at all enough, and he thinks there is nothing else in the world he wants more

than for Diluc to play with his chest until he comes, over and over, just from that, even if it means losing.

"This is *cheating*," he grits out, although there is no heat in his words. His chest feels so hot that surely it's flushed, by now, but he makes no move to touch it.

"I don't think it is," Diluc replies, circling his now oil-slick finger around Kaeya's rim and smiling when Kaeya twitches bodily at the sensation. He raises Kaeya's boots-clad legs, propping them over his shoulders, and oh, oh—Kaeya can see his own length, now,

that traitorous organ embarrassingly hard, precum beading on its slit. "I'm only leveling the playing field, considering you decided to show up with *this*."

There is no warning when Diluc presses a finger into him—faster, harder than strictly necessary. Just the way Kaeya likes it, the burn made heavenly by the Diluc's warmth and the oil both.

His body jerks violently, his spine curved taut in pleasure as Diluc adds another finger just as fast, just as hard, curling them just so until they are pressed insistently against the bundle of nerves that dissolves the words on Kaeya's tongue into moans.

"You're, *ah*—a terrible person, Master Diluc."

"Am I, now?" he presses ever so slightly harder, his lips twitching with amusement as he feels Kaeya's legs kicking against his back. A droplet of precum rolls down Kaeya's length.

He presses harder.

"Luc—!" Kaeya keens, his vision whiting out as he bpulls Diluc down for another kiss, this time all teeth, as if that could stifle these noises coming out of him. He presses his lips on the sharp bone of Diluc's jaw, his neck, his collarbones—his proof of ownership over a king.

"Fuck me," he breathes out, less of a plea and more of an order, his hole clenching around the warmth of the fingers inside him.

"Hmm," Diluc's smile widen as he presses another finger inside, then another, until everything feels like erring on the side of too much.

Diluc knows this, of course, that *asshole*, his gaze bordering on lecherous as he watches the way Kaeya's moans turn into a string of *ah-ah-ah*s. "Such tall orders, Sir Kaeya. I don't mind, of course, but—"

Kaeya think he will not forget this moment anytime soon—this overwhelming feeling of fullness, the warmth that seems to cling to his insides, and Diluc's expression when he says: "I want to see you come by my fingers alone, first."

(break for me to consider my life choices and learn how to actually write smut🔥❄️)

bingo square for this part: mild nipple torture (?), genshin-related kink. 2.3k words in and we're *still* at foreplay. how. why. i skipped gnshn's daily commission freemogems for this.

"That's—*haa*, a bit cruel, don't you think?"

He is *trying*, he tells himself. He refuses to let Diluc win, just like this—with his fingers stretching Kaeya's rim deliciously taut, the insistent pressure unbearable.

His free hand, gloved still, brushes against the side of Kaeya's neck and down, down, until it wraps around Kaeya's waist, pressing him deeper into the mattress.

"Cruel?" Diluc's remark is that of amusement, his eyes bright as he begins scissoring his fingers inside, brushing Kaeya's prostate with such deliberate gentleness until there is nothing else Kaeya can do but clenches and squirms around the fullness.

When Diluc presses against it with the tip of his fingers, the sensation is enough to bring tears to Kaeya's eye as he *wails*, bucking into the fingers only for Diluc to press harder, playing with the bundle of nerves until what is left of Kaeya's voice is a long, drawn-out sob.

"Good," Diluc's voice has taken a huskier tone as Kaeya's body twitches helplessly around him. Kaeya's dick is practically drooling with precum, now, just from his fingers alone; his nipples are pebbled, still, and reddened by the heat of the flaming essential oil.

His face is blotched, tears-streaked—already Diluc wants to undo him even further, until there no remains of Kaeya's placid geniality is left.

The night is still so, very young.

"You're made for this, aren't you?" he continues, pulling his fingers out so quickly that Kaeya gasps at the too-sudden emptiness before he pushes them back in—again and again, feeling the way Kaeya's rim clings to his fingers every time he does so.

Kaeya is more pliant than usual, under him, more welcoming—Diluc watches, half-amused, as he puts a gloved hand against his mouth and *bites*, as if that could stop the embarassing noises that Diluc is drawing out of him.

His dick, pressing against his stomach, is so hard it looks almost painful. Diluc knows he can make Kaeya come, by now, if he were to give it even the gentlest stimulation, but Kaeya wants fun, doesn't he? And so he will get *fun*, because Diluc is nothing if not accommodating.

"I can't—" Kaeya pants, even as his legs tighten where they are wrapped around Diluc's shoulders, his hips canted to meet Diluc's thrust. "I *can't*."

"Oh, but you can."

His next thrust forces another wail out of Kaeya.

Another drop of precum beads at the head of Kaeya's dick—Diluc licks his lips at the sight. "See? You're almost there."

"*Ah*," Kaeya gasps out, blinking back overwhelmed tears. "You're so, *so*—"

Neither of them will ever know what Kaeya is about to say, because a particularly hard trust against Kaeya's prostate turns his voice into a sharp, desperate cry as he comes all over his chest, so hard that his body trembles with its aftershock.

Diluc kisses him, then; tastes his tears on his lips as he brushes Kaeya's sweat-sticky bangs away from his reddened eye, murmuring soft praises into Kaeya's ears as Kaeya's body continues to twitch under him, his hole clenching and unclenching around nothing.

"You did good, Kaeya," he says, smiling into the kiss. "You did so well for me—I knew you can do this, just for me."

"Luc," Kaeya breathes out, narrowing his eye as if to bring the world back to focus.

Diluc can feel how hard he is breathing as he kisses him back with his eye closed, open-mouthed and messy, yet there is tenderness there, too, that Kaeya does not try to hide. A softness like silk, hiding the sharpness of steel underneath.

That alone should have alerted Diluc, in any other time—this knowledge that Kaeya is never truly *soft*, in this little game of theirs, not unless he is planning something.

The realization comes to him a second too late—enough for Kaeya to *smirk* into the kiss as he grabs the front of Diluc's shirt, flipping him over to trap him between those strong, sculpted thighs.

"My turn for *retribution*, now, Master Diluc."

(another break 🔥❄️ 3k words in and *still* no dicking so kaeya is going to take this matter into his own ass--i meant hands)

kink in this part: mild praise kink

if you're enjoying this long-ass horny july entry (or my other works) i do have a ko-fi!
ko-fi.com/cryovishap

He thinks he loves Diluc best like this: under him and out of breath, his world narrowed down to Kaeya alone. His dick is painfully hard, Kaeya notes gleefully as he wraps his hand around it and strokes, the blue of Eula's glove a nice contrast against the reddened flesh.

Diluc groans at the sensation, his grip on the bedsheet so tight that his knuckles turn white. The sight is enough to make Kaeya's spent dick twitch in interest, his hole clenching in obvious arousal.

He is loose enough to take Diluc now, he knows; overstimulated enough that the pleasure would border on being tantalizingly painful. And Diluc is hard enough that he can come just from the sensation of Kaeya's gloved hand around him, but he won't—they both hate losing, after all.

"Poor thing," Kaeya coos, running his fingers from the base of Diluc's length to its leaking tip, smiling when Diluc trashes under him at the sensation. Kaeya squeezes his thighs closer together, biting back a moan as the gesture makes his dick rub against Diluc's own.

It is hard not to admire the contrast between them—like this, with Kaeya on top of him, Diluc's length is brushing just under his navel, bigger than anyone or anything Kaeya has ever taken.

He doesn't think he would ever get used to it, not fully—the wonderful burn of the initial penetration, the way it always, *always* presses deliciously against his prostate even without him trying.

Kaeya licks his lips as he grinds their arousal together, watching as more precum beads on the Diluc's tip. He gathers it with his thumb just to see Diluc bucks against him once more, his face so red that it matches his hair. Fine, he thinks, maybe they both deserve their reward.

"Stay still," he orders, and Diluc obeys, his thighs tense as Kaeya lifts himself up, just so, until the tip of Diluc's erection brushes against his hole.

It twitches in interest, but Diluc makes no move—it's such an impressive display of resolve that Kaeya cannot wait to ruin it, the way Diluc ruins his every mask.

He lowers himself, inch by slow inch, biting his lips to keep from moaning because even Diluc's *very* thorough preparation cannot fully prepare him for how the head of Diluc's cock seems to carve a place inside him, hot and heavy as it drags against the tightness of his walls.

"Kaeya—" Diluc gasps out in wondrous pleasure, his darkened eyes watching intently as Kaeya finally, finally impales himself fully on his cock. The pleasure burns, curling inside him like flame as Kaeya clenches around him, the sensation made even more intense

by the warmth of the flaming essential oil that he has so thoroughly coated Kaeya's insides with.

"Oh," Kaeya breathes out, looking down to his stomach with such hunger in his eye that Diluc cannot help but look, too.

"*Oh*," he echoes, because what else is there to say, when he can see the faint outline of his dick through the flat of Kaeya's stomach?

(break for the night!! this work is getting out of hand send help)

kink in this part: dick riding + stomach bulge

this is baby's first proper smut so if you enjoy this so far, moral support in form replies/likes/RT/QRT are all appreciated ❤️💙

Kaeya reaches for the bulge, as if mesmerized, his mouth hanging open and his pupil blown so wide that it looks nearly round. His fingers brush against it tentatively, at first, and Diluc swears he can see the way his dick twitches in interest behind the stretch of Kaeya's skin.

For a few long, torturous seconds neither of them moves, mesmerized as they are by the *impossibility* of it all—that Diluc has carved a space for himself within Kaeya; that Kaeya can swallow him whole, like this.

But then Kaeya lifts himself up fully, until the tip of Diluc's cock rests *just* inside him, still breathing hard, pausing for half a second before he slams himself down one more time, pressing down on his stomach as he does so.

The sensation is nearly impossible to describe—the slick tightness of Kaeya around him, the pressure of his gloved fingers, the tingling warmth of the oil that turns every sensation into a liquid pleasure.

Kaeya does not stall, this time around—he lowers himself down on Diluc's length, over and over, his hand pressing *just* over the bulge, framing the way his stomach stretches to accommodate Diluc whenever he's fully seated inside him.

"H-here," he breathes out, taking hold of Diluc's hand to let him feel it, too. Diluc cannot help the moan that escapes his lips, then, or the way he tries to pull Kaeya down for a kiss, all thoughts about their game forgotten in the blissful whiteness of pleasure.

Kaeya indulges him, smiling into their messy, open-mouthed kisses, his own growing erection trapped between their bodies. His rhythm becomes increasingly erratic—with their bodies pressed this close together, Diluc can feel Kaeya's every twitch whenever Diluc's length drags

against his prostate, his eye shut tight and his mouth open in wet, wordless moans as he shivers bodily at the sensation.

Diluc can feel his orgasm incoming, a molten pressure building inside him. "Kaeya," he gasps, hands reaching out to pull him into another kiss. "Kae—!"

"Luc, I—" Kaeya's thighs are shaking with effort as he lifts himself up, tears of overwhelmed pleasure gathering on his lower lashes even as he drops down, sheathing Diluc fully inside him one last time before Diluc feels himself spilling,

so hard that the aftershocks make his toes curl up as he spasms.

The feeling of Diluc's cum, the knowledge of it coating his insides, sends Kaeya into an orgasm, too, clenching around Diluc's spent dick as he paints the front of Diluc's shirt in white.

He slumps on top of Diluc, still shaking with pleasure as he buries his head in the crook of Diluc's shoulder and *bites*, until he has wrung out every last drop of cum left in his body.

They lie together, just like that, for the longest time. Their breathing is the only sound filling the room, hot and heavy, loud as the thrumming of their heartbeats, until—

"I won," Kaeya mumbles weakly, his voice shaky.

Diluc can contest him, then, or argue about the technicalities of *victory*—the way he usually does, for this game of theirs. He chooses neither, this time.

"You did," he says, pressing a kiss to the crown of Kaeya's head as he rolls them around, gently pulling his spent length out of Kaeya to lie down next to him. The bed really is not made for two people—Diluc knows both of them would be sore, when morning comes. He does not care.

"I want three bottles of dandelion wine, as a reward," Kaeya mutters.

"One bottle."

"Two bottles *and* a glass of whatever new cocktail you're creating."

"One bottle and three glasses of my cocktails."

Kaeya huffs in exasperation, but he nods, in the end, kissing the corner of Diluc's mouth. "Deal."

Diluc kisses him back. He wraps his arms around Kaeya, fully ready to close his eyes and sleep when he remembers one last, important thing:

"Hey, Kaeya—can you keep the boots and the gloves?"

Kaeya's answer is a sharp kick to his lower legs.

It's not a no.

(THE END FINALLY 🔥❄️)
