Chapter Text
Diluc stared at the shop front warily, wondering if maybe this was another trick Lisa had played on him. He'd been having brunch with her and her girlfriend, Jean. They'd been friends for years. Diluc had been forced to sit through their mutual sapphic 'oh, but I don't think she like-likes me, Diluc' phase, and thus the pair were convinced it was their responsibility to look after Diluc's romantic (Jean) and sexual (Lisa) wellbeing. The pair were overly concerned with Diluc's 'dry spell' and 'lack of an outlet'. Diluc had testily reminded them, for nearly the twentieth time, that he was fine being single and didn't have any needs that needed sating.
Jean had recommended a dating app. Lisa had recommended…
This.
Lisa's cut and dry explanation was that maybe regular sex was too boring for Diluc and that he needed to 'spice things up'. Diluc scoffed at that, glancing away. But Lisa was a menace; a vicious, intelligent, sharp-witted menace that knew that Diluc's curiosity was one of his major vices.
Thus she'd texted him the address and a cheerful note to talk to 'Kaeya' if he had any questions.
The name of the store was Khaenri’ah's Delights. Diluc didn't know any place called Khaenri’ah, but the 'Delights', from what he saw through the window appeared to be anything from books on romance to piercings to surprisingly modest clothing. It looked absolutely nothing like a sex shop.
Diluc narrowed his gaze, before walking up and pulling open the door. The bell on it jingled merrily to announce his presence as he stepped inside and took in his surroundings.
Instrumental music played overhead, which Diluc immediately recognized as Einaudi's Passaggio. A warm feeling bubbled in the pit of his stomach at the song. He remembered his mother, young and regal, playing the violin in a way that even now he could only hope to mimic. Maybe the feeling of calm that washed over him was the only thing that prevented him from turning around and leaving immediately when he took in the sight of the shop.
The lighting was soft but still bright enough that he could see easily. The front of the shop was surprisingly simple. More books, some that looked like actual literature and others that had decidedly more sexual pictures on the cover, filled the beginning of the left wall. Beyond that was a wall of lingerie, in every shape and color, and material. There was pink lace, black silk, and what Diluc thought might be just tiny, tiny chains meant to appear like underwear. He quickly glanced away in embarrassment.
The right side of the store featured a shop counter, flyers tucked neatly into a stand on its left, and a sizable shelf of condoms and lube on its right. The counter was currently vacant, but behind it, Diluc could see a variety of boxes, ranging from small to large, of what he realized were vibrators.
The front and center display appeared to be seasonal. With Christmas rounding the corner it featured a wealth of anything from reindeer to elves to the classic Santa attire. Shockingly though, the outfits were surprisingly tame.
Aside from the condoms, lube, and vibrators, Diluc would have pegged this place for a weird lingerie store, rather than the kinky BDSM hovel that Lisa described it as.
After a moment, Diluc walked deeper into the store, largely seeing the same story. Lingerie, books, and the occasional costume clothing. Though, if he were to be honest the costume pieces here were of a far higher quality than something a Halloween costume shop would gather up.
He was busy running his finger over a black cat ear affixed to a headband when someone cleared their throat behind him. Diluc startled, turning around quickly.
The man standing before him was handsome, ridiculously so. His hair was a deep azure and pulled over one shoulder, his one visible eye twinkling like the reflection of the night sky in the ocean. He was dressed in a shirt with a deep enough 'v' to show not only his defined chest but also his very defined abs. His pants were skintight in a way that left very, very little to the imagination. It was a very sharp contrast from Diluc's turtleneck and jeans and boots.
The man cleared his throat again and Diluc realized that he'd been staring at the stranger's chest for far longer than was appropriate. Diluc raised his gaze to the man's jaw, refusing to meet his eyes as he considered turning tail and running out of the store at that very moment.
"Are you looking for something in particular?" The man asked, his voice polite and smooth. Diluc swallowed thickly, shaking his head, before considering.
"Well, actually," he began, thanking every God in the world that his voice didn't crack like a preteen. "My friend, she, uh, she told me to ask for a 'Kaeya'?" He said, finally managing to meet the man's gaze once more.
The man smiled at him knowingly. Diluc fought the urge to blush with every part of his psyche.
"I'm Kaeya," he said easily. Diluc blinked. "And you are…?"
"Diluc," he said after a moment. Kaeya nodded his head easily.
"A pleasure to meet you. I'd ask who your friend is for suggesting such a referral, but discretion is a guarantee in this shop." He tilted his head, looking Diluc over. "Though you look completely lost in here. Are you maybe looking to spice it up in the bedroom with your partner?"
"I don't have a partner," Diluc replied quickly, glancing away.
"Ah, a solo experience then?"
"I...she recommended I come here and I was curious," Diluc muttered, eyeing the shop walls, from the books to the lingerie.
"Curious about anything in particular?" Kaeya asked easily, still looking Diluc over. "I'm sure I have a few pieces in your size." He added. Diluc wondered if maybe Kaeya was watching him a little too closely. He flushed, crossing his arms over his chest.
"I'm not into that," he replied firmly. Kaeya smiled at him politely, but the glint in his eye was anything but.
"What a shame, I have a few things in mind you'd look wonderful in."
"Do you normally picture your customers in lingerie?" Diluc asked warily. Kaeya grinned.
"It comes with the job. You'd be surprised how many people will blindly pick out something that doesn't suit them at all. It's my job to make a proper recommendation." Kaeya tilted his head, looking Diluc over in an entirely personal way. "Though, I can say I do enjoy doing it more so when the customer in question is stunning to look at."
"I…" Diluc sputtered when Kaeya's words caught up to him. He swallowed the knot in his throat, looking away. "Regardless, lingerie isn't something I'm interested in."
"Do you have anything, in particular, you'd like to see?" Kaeya asked, looking only slightly disappointed.
"I…" Diluc glanced over to the cat ears he'd been looking at before. "Ah, this is popular, isn't it?"
"Kitten play? Yes, very much so," Kaeya replied easily. "I have some more selections in the back of the store if you were interested."
"Ah, okay," Diluc agreed. Kaeya turned to walk towards the back of the shop. Diluc was unable to stop himself from admiring Kaeya's ass. God, he was acting like a teenager all over again. Kaeya led him around a corner and suddenly the merchandise became a lot more...intense.
Leather and chains dotted the walls in the forms of anything from whips to leashes. Lingerie, now in colored leathers and bright latex covered the walls. Diluc stared as Kaeya led him over to a corner that hosted a collection of collars.
"I...uh," Diluc began, looking over his shoulder at what appeared to be some form of medieval torture device.
"Ah, don't worry, that's only for display," Kaeya said, following his gaze. Diluc looked back at him as Kaeya turned his attention to the wall of collars. "Every kitten needs a collar...as for which one might appeal to you...how about this?" He suggested, plucking it off the wall. It was cherry red, the band soft silk, the inside lined with black fur. "The clasp is easily undone without assistance, and the material on the inside is rather nice. Would you like to try it on?"
"Try it on?" Diluc echoed. Kaeya smiled at him.
"Of course, this is for your personal use, after all…?"
"I...what if I don't want to dress up like a cat?" Diluc muttered, glancing away. Kaeya studied him silently for a moment before replying.
"This shop is about providing you with all you need for your desires," Kaeya said. "I've seen plenty of people come in here, fronting as someone they're not and leaving wholly miserable because of it. Against my advice of course." He sighed. "You're new at this, aren't you? It's difficult to dive into this scene when you don't have a committed partner to explore with. Even if you did end up finding a partner, I wouldn't want your first experience to be a bad one." He added, looking genuinely concerned. Diluc glanced away, embarrassed.
"I...I don't have any reason to search for a partner. Like I said I'm just curious." He explained.
"Well then, there's no shame in trying something on, is there? You can take it off when you're done." Kaeya pointed out. Diluc bit his lip, before lifting his chin for Kaeya to put the collar on. Kaeya hesitated until Diluc looked at him in confusion.
"Is something wrong?" He asked. Kaeya paused, looking almost embarrassed.
"Ah, it's nothing," he said after a moment, fixing the collar around his neck. The collar rested easily around the base of Diluc's neck, the fur comfortable and soft. Diluc reached up to brush his fingers against it, blinking when he realized that he was blushing. The lightweight shifted something within him until he found himself playing with the collar almost absentmindedly.
"It suits you," Kaeya said, his voice wavering. "It suits you very well." He added, his gaze fixed on Diluc. "I have a matching leash if you're interested." He added.
"It's not like there's anyone to hold it," Diluc pointed out, shocked at how the idea actually seemed to bother him. He'd been single for years now without consequence. Now he was starting to feel sentimental because of a strap of silk?
"That certainly is a shame," Kaeya agreed after a moment. "I'd be lying if I said I wasn't shocked that you're single." He added, clearly admiring Diluc. Diluc narrowed his eyes at him.
"Is that something you say to all of your new customers?" Diluc asked suspiciously. Kaeya smirked at him.
"No," Kaeya answered as he shifted closer, his hands dragging across the wave of leather leashes in such a casual way. Diluc swallowed thickly. "I believe that it's bad for business. But I'm only human. It's not every day someone as pretty as you walks into my shop without a Dom wrapped around them possessively."
"Oh," Diluc breathed, looking away. Warmth pooled in his belly at the compliment, the skin on his arms tingling in delight. "I...who says that I'm not a Dom?" He asked weakly. Kaeya chuckled, low and sweet.
"Oh kitten," Diluc refused to acknowledge how easily the name made him shiver, "you're so adorable." Kaeya's hand went to his neck, thumb rubbing over the collar. "Doms don't react like you do when they get collared. Only pretty, sensitive subs do." Kaeya murmured, his gaze roving over Diluc appreciatively. "You could try to Dom someone, of course, I'd even let you try it with me, but I don't think that's what you want, is it?"
"I...I don't know…" Diluc mumbled, blinking when he realized that he was all but leaning against Kaeya at this point.
"I bet you'd make such an adorable little shop kitty, dressed in some of my prettiest clothes. Nothing too lewd, I'd hate for you to catch a cold, but letting you walk around, letting the other customers see how pretty you are. They'd approach you, only to see this collar around your neck with my name on the tag. They'd certainly wouldn't try anything if they knew what was best for them." Kaeya purred, an arm going around Diluc's waist. Diluc moaned softly, his skin feeling flushed all over.
"U-um, I…" Diluc moaned, blinked when Kaeya pulled away abruptly. He looked up in shock, blinking at the embarrassed flush to Kaeya's cheeks.
"Forgive me, I got ahead of myself," Kaeya said quickly. "I shouldn't have touched you without permission." He explained at Diluc's dazed confusion. Diluc blinked, his head clearing slowly. Still, he looked back at Kaeya, unable to meet in his eyes directly from sheer embarrassment over what he was about to say. He fixed his gaze on his collarbone instead.
"You have my permission," Diluc breathed, pressing up against Kaeya's chest. He was shocked at his own boldness, as was Kaeya apparently.
"Diluc, I-"
"Please," Diluc murmured, his cheeks feeling as though they were going to light on fire. "Don't make me beg for it." He added, shivering when Kaeya's arms came around him.
"What a shame. I want to hear you beg." Kaeya replied, leaning closer. Diluc tilted his head up, meeting Kaeya's lips. He moaned, pressing closer, whimpering when Kaeya pulled him flush against his body. Kaeya's tongue slipped into his mouth, with a kind of casual dominance that made Diluc shiver. Diluc sucked on Kaeya's tongue, his own pushing against his eagerly. Wet, filthy grunts and gasps filled the air between them. It crossed a line in the sand that Diluc didn't know he'd drawn ages ago.
It was true that he hadn't had sex in a long time, but even in his young and stupid college years sex hadn't felt like this. Not nearly as much heat and smoke. He'd always held himself to a certain expectation during sex, but Kaeya was quickly shoving past those barriers in search of a part of him that was far more carnal. Diluc gasped when Kaeya's hands slid to his thighs, abruptly tugging him into the air. Diluc's legs wrapped around Kaeya's waist as he was pressed against the wall of leather, Kaeya's grip tightening on his thighs when Diluc moaned.
"God, you're adorable," Kaeya muttered against Diluc's lips. Diluc whined, chasing his mouth for more kisses. Kaeya growled, kissing him back hungrily until Diluc was gasping for air. "I want to make you mine." Kaeya hissed, groaning when Diluc squirmed in his arms, rutting against the front of his pants. "Kitten," his tone was a warning, "settle down, or I'll drop you on accident."
"Kaeya," Diluc whined, arms wrapping around his shoulders tightly. "You don't have a bed here?" He asked, gazing at him demandingly. Kaeya paused, looking conflicted.
"We have things we should talk about first. Safewords, limits-"
"Do you need all that if you're just going to fuck me?" Diluc snapped, frustrated at Kasya's hesitancy. "I just," he whined, squirming in Kaeya's arms, "I just want your dick in me right now." He whimpered, rolling his hips as Kaeya moaned out a laugh.
"And here I thought you were a shy little thing. You're actually quite the minx, aren't you?" Kaeya replied, a smirk spreading across his lips. Diluc flushed, glaring at him.
"If you keep stalling then I guess you'll never find out, will you?" Diluc replied sharply. Kaeya lifted a brow, looking amused.
"Impatient with an attitude as well. I like that in a kitty."
"I like cock. Right. Now." Diluc bit out. Kaeya laughed, letting Diluc down in favor of tugging him along, deeper into the shop, until they came into a room that could only be described as a sex dungeon.
The walls were painted black, everything from whips to leashes to what looked like torture devices hanging merrily from racks on one wall. Foreboding cabinets were tucked alongside another wall. The bed was massive, with black sheets and too many pillows to count.
Diluc paused for a moment, Kaeya taking note. Kaeya turned to him, his expression gentle.
"We don't have to do this." He said gently. Diluc shook his head, already pulling off his own shirt and kicking off his boots. He was determined at this point. "Well, if you want to stop just tell me." Kaeya mused as Diluc flung his shirt aside, going for his pants next.
By the time Diluc was naked, Kaeya had only got his shirt off. Diluc stepped forward, hands impatiently going for Kaeya's pants. Kaeya chuckled at his eagerness, letting Diluc pull out his cock.
"Oh fuck," Diluc whined. Even half-erect Kaeya was huge. Thick and heavy, no wonder he was in the business of sex. He could have doubled as a porn star. Diluc bit his lip, stroking the shaft of Kaeya's cock, shivering as it grew harder and hotter under his touch.
"Like what you see?" Kaeya asked lowly, hands going to the collar around Diluc's neck. He hooked his finger under the material. "Should we take this off?" He added.
"Keep it on," Diluc answered, his gaze fixed on Kaeya's cock almost helplessly. "I want your cock down my throat." He moaned. Kaeya swore, pulling Diluc's hand away.
"On the bed, now," he ordered sharply. Diluc whined, complying as he stumbled for the bed, climbing onto it eagerly. Kaeya sat on the edge of the bed, Diluc moving to crawl into his lap. Kaeya sent him a quelling look.
"On your stomach, face in my lap," Kaeya ordered. Diluc slid down, his body stretching across the bed as he leaned closer. Kaeya's cock was larger upfront, thick and long. Diluc squirmed on the bed, rutting his cock against the soft sheets. He moaned, gasping when a hand gripped his ass tightly, squeezing. "Don't get distracted now. What did you just tell me that you wanted?"
Diluc didn't bother to reply, shifting forward to grab onto Kaeya's cock with one hand, his tongue sticking out to drag a long line up the length of his cock. Diluc groaned, shifting closer, his lips wrapping around the head as he suckled at the tip, his hand stroking down the shaft and gripping firmly.
"Oh, you enjoy this, don't you?" Kaeya murmured, stroking Diluc's hair. "And here I was concerned I'd found another pillow princess that I'd have to teach how to choke on a cock properly."
Diluc whined, bobbing his head down to let Kaeya's cock slide further into his mouth. His tongue worked across the heavy heat in his mouth, delighted moans spilling from his throat as Kaeya continued to stroke and pet his hair. He gagged when Kaeya hit the back of his throat, before stubbornly swallowing him down further and further until his lips brushed against dark curls. Diluc preened when Kaeya growled above him.
"Fuck, you're good at this, aren't you?" Kaeya hissed, his grip in Diluc's hair tightening. Diluc mewed around his cock. "You like being treated like this, huh?" He asked appreciatively.
Diluc pulled off Kaeya's cock with a filthy wet sound, messily sucking along his shaft. His mind was hazy, his body squirming as he worshipped the dick in his hand with his full attention. His focus narrowed until he was only dimly aware of something spreading his cheeks, a shrill moan escaping his throat when a slick finger pressed inside him.
"Too tight to have been used recently though," Kaeya mused. "Just a lonely kitten suffering through your heats, aren't you?"
Diluc moaned against Kaeya's cock, quickly taking it into his mouth again, whining when Kaeya's finger worked deeper into his hole. He bobbed his head up and down, sucking hungrily as he eagerly worked Kaeya's cock.
"Take my cock again, kitten. All the way. You know exactly how, don't you? Cute little thing," Kaeya groaned. Diluc sank his head down, Kaeya's cock stretching his throat again. It felt so good, so right. Like this was what he was meant to do for the rest of his life. A part of him revolted at the idea, but his brain was quickly becoming a haze of pleasure and delight, only pierced by Kaeya's voice.
Fuck, it was so good. Regular sex wasn't going to cut it anymore. Damn it.
He choked when Kaeya's fingers pushed against his prostate. He gagged, trying to pull away. A firm hand in his hair held him fast.
"Ah, ah, what did I say?" Kaeya said cooly. Diluc whined, sinking back down onto his cock, hands going limp in Kaeya's lap as Kaeya petted his hair affectionately, his other hand working Diluc's hole open with precision.
"Good kitty. You know how to be good, don't you?" Kaeya praised. "Sometimes that's the hardest thing to teach. Even the brattiest of kittens want to be good deep down, but actually being good is a different story."
"N-Nnn…!" Diluc whined around Kaeya's dick.
"I think your cute hole is stretched enough to take my cock, don't you?" Kaeya purred, stroking Diluc's hip. Diluc pulled himself off Kaeya's cock with a gasp, looking up at him eagerly.
"Yeah," Diluc agreed hoarsely, climbing to his hands and knees. He scrambled into Kaeya's arms, straddling his waist. Kaeya chuckled, his gaze drifting to Diluc's wet hole. Diluc whimpered when he felt the head of Kaeya's cock against him, gasping when the head pushed inside him. "Fuck, you're huge."
"You're tight," Kaeya groaned, squeezing Diluc's hip tightly. "Relax, kitten, you're going to snap my dick off at this rate." He ordered gruffly. Diluc moaned as Kaeya's cock spread him wider and wider. His body both rejoiced and protested. He wanted to squirm but Kaeya's iron grip denied him even that.
"Fuck, I can't- "
"Relax." Kaeya tugged at his collar firmly, dragging him back to the present. Diluc couldn't stop the moan he made at the rough treatment. "Breathe, in and out, like a good pet." He ordered. Diluc drew in a slow, shaky breath. "Good kitty. Again. Until this hole takes my cock properly."
Diluc breathed, slow and steady, soft moans escaping his throat as he sank down on Kaeya's cock, until he was seated fully on Kaeya's lap, nails scratching at his chest as he struggled to process just how deep Kaeya was inside him.
"There you go, good kitty," Kaeya praised, kissing his jaw sweetly. Diluc flushed, burying his face into Kaeya's neck. "Ah, don't like that?"
"More like I like it too much," Diluc mumbled against Kaeya's neck.
"Adorable. I'll have to remember that, won't I?" Kaeya replied, his hands slipping to Diluc's thighs. "Now, kitten, don't be lazy, earn your collar properly." He ordered. Diluc shivered, grabbing onto Kaeya's shoulders as he lifted himself up on Kaeya's cock, before sliding back down. He moaned, quickly picking up the pace as he chased his own pleasure. Kaeya was so big his cock hit everywhere at once. It was ridiculous how good it felt.
"Fuck, ah-Kaeya…!" Diluc gasped, grinding his hips down, his back arching as Kaeya began to mouth over his neck, leaving rough, bruising marks. "Ah, fuck !"
"Such a mouth on you. Cute kitties don't swear, we'll have to work on that." Kaeya said, gripping Diluc's hips tightly. Diluc whined, fucking himself on Kaeya's cock, his moans growing louder and louder until he choked out a yell as he came across Kaeya's stomach. He trembled around Kaeya's cock, rocking his hips as he rode the waves that trembled through his body. God, he couldn't remember the last time he'd felt so good after an orgasm. He stuttered to a stop, still seated on Kaeya's cock, trying to catch his breath.
"You're rather adorable but obviously untrained. We'll need to work out some of your bad habits, kitten." Kaeya muttered, shifting his grip to Diluc's waist. Diluc yelped as they were flipped over, suddenly on his back underneath Kaeya.
"W-ah! Wh-what?" Diluc moaned, clinging to Kaeya as his hips thrust forward sharply.
"Cursing, not asking for permission when it's due, not looking to your Dom's pleasure, and being greedy with your own. Just to name a few. But don't worry, I'll teach you properly." Kaeya said, grinding his hips forward. Diluc keened, his head falling back against the bed.
"K-Kaeya, please…!"
"Please what?" Kaeya asked lowly. Diluc moaned, his eyes hazy as he looked up at him.
"Cum inside me, please!"
"Yeah?" Kaeya's voice grew shaky, his gaze riveted on Diluc's face. "You want that?"
"P-please….I want it!" Diluc whined, clinging to him. "Cum...please, your cum, I-" Diluc gasped as Kaeya's pace grew frantic, his thrusts so rough Diluc slid up in the bed before Kaeya's hips jerked to a stop against him, the other man groaning as he came inside. Diluc shivered at the wave of satisfaction that rolled through him as Kaeya got off. It was more than the simple polite act of letting a partner orgasm, it was something far more...strange and novel.
Kaeya drew in a ragged breath, looking at Diluc with nothing short of adoration on his face.
"That was amazing," he praised. Diluc flushed, glancing away. He winced when Kaeya pulled out slowly. Oh God, he was a mess. "There's a shower in the next room," Kaeya said, already anticipating his needs. "Do you need help standing?"
"I'm...not sure," Diluc admitted. He felt strangely vulnerable in the aftermath. More open and exposed than with previous partners. Kaeya smiled at him easily, pulling himself out from between Diluc's legs. He helped to tug Diluc to his feet, steadying him when he wobbled.
"Here," Kaeya said, undoing the clasp of the collar. Diluc watched as he tossed it back onto the bed. He didn't realize he was pouting until Kaeya's thumb rubbed against his lower lip. "Don't be sad now, the material isn't waterproof."
"Do you have one that is?" Diluc asked curiously, shocked at how attached to the collar he was.
Or maybe it was the fact that Kaeya had put it on him in the first place.
"I do, but collaring is something special we should talk about more, darling," Kaeya said, tugging Diluc along to another door. "Let's get you cleaned up, grab you something to eat, and we'll talk about this properly, okay?"
"Okay," Diluc replied, unable to stop the warmth that blossomed in his chest at Kaeya's words.
