“I— I don’t know,” you were sheepishly whispering in furious puffs of hot air against the fabric of his glove as it lightly pressed over your lips, your eyeline flickering to the chapel doors. “I don’t think I’m supposed to be doing this…” thankfully, the doors were still shut. however, you knew that at any moment, any one of your sisters could stroll inside and see you clinging to the Calvary Captain, your body pressed against the altar and angled with one ankle hooked up on his waist.
“Shh, shh, shh…” Kaeya had a gentle voice, though. a smooth, easy tone in which he crooned in your ear. “What did I tell you, sweet girl?” he asks, but he doesn’t wait on your answer, planting a soft kiss against the shell of your ear. “Blessing me before a daunting mission is part of your duties. You do want me to return to Mondstadt unharmed and victorious, yes?”
“O-of course, but—“
but you weren’t so certain that his free hand slipping between your legs and cupping your core under your skirt was allowed. you were still learning the ins and outs of your new life in Mondstadt, and what was expected of you as a servant of Barbatos, but something about the swiftness of his movements, as if he were hyper aware of the surroundings and the need to take what he wanted quickly, and the sugary whispers into your ear, as if he didn’t want anyone else to hear, clued you in: you shouldn’t be allowing him this access to your body.
“Of course you do,” he swoons, long and svelte, strong fingers teasing the fabric of your panties. you can’t help but let out a flustered whimper at the brand new, electrifying sensation, one of your own hands reaching down to clamp a fist around his wrist. “Because you’re a good, good girl, aren’t you?” he chortles, as if amused by the sentiment.
you nod, your countenance scrunching as he presses his fingers hard against your button through the now damp fabric. you wanted to tell him yes, but the sensation caught you off guard, and he had to cradle your mouth tighter in his palm to keep you from crying out. the little sound that did escape, however, spurred an elated twinkle in his eyes. he clearly liked the way your body responded to him. “Aw, such a sensitive, little sweetheart. You’ve never felt this before?” he was nearly taunting you, a killer smile dancing along his lips as he pulls back just enough to study your face. from where he stood, he was still taller than you, even with you boosted up on the second step of the altar, his tiers are parted, allowing ragged, warm breath to pass through and tickle your steaming cheeks.
“N—no, I’ve never—“ peeking up at him, your body writhes at his merciless rubbing. “I’ve never been touched like t-this…” for some reason, you felt embarrassed. you wondered just how many sultry, experienced women Kaeya Alberich has slept with, and here you were, unable to hold consistent eye contact with his hand between your legs. “I-I’m not supposed to—“
“With me, it’s okay.” he assured with a smirk, “Trust me, sweet girl.” you wanted to. you wanted to so badly that you nod, slowly, staring up at him in awe and wonder. he chuckles, and nods, his hand on your mouth careening downwards to hook his forefinger beneath your chin and guide your face up higher, angle it for his lips to find yours. “There you go. I can see it in your eyes. Just keep looking at me like that and I will take good care of you, little sister.”
his fingertips work in tandem with his words, pulling your panties to one side so he can feel your slick— vulnerable and bare. and you whimper, your grip tightening around his wrist when he pushes his middle finger inside. his tanzanite gaze lingering on your face to gauge your willingness. “My, my, you are tight, hm?” he grins, allowing his knuckle to act as a bumper, ensuring he doesn’t push too deep too fast, and instead, he twists the digit, curling to tease your spongy, clenching canal. the feeling of your spasming from the inside releases a guttural groan that bubbles up slowly, vibrating in his mouth. “I’ll have to be so gentle with you, I’d bet you’d sing like a pretty little bird if I put my cock in you.”
you exhale a breath of shock or, perhaps, excitement. the idea of him taking you so carnally had your head spinning.
“K—Kaeya, you can’t—“
he grins at that, rubbing his finger pad along the side of your fluttering interior, and you practically melt against his sturdy chest. “Oh, I wouldn’t dare. Not until you’ve been properly trained. What kind of a man do you take me for, sister?” his voice is full of playful nature and giddiness, before he pecks your lips again. there’s something lurking beneath his soft, hypnotizing voice, but you can’t place it. you can’t imagine Kaeya to be wicked, so you let the fleeting clue dissipate. “But you will still have to bless me somehow, no?”
“How?”
maybe you shouldn’t have asked, because your cheeks burned like twin ovens when Kaeya dropped to his knees before you.
“W-what are you—?!”
Kaeya laughs again, his fingers slipping from you to, instead, trail along the back of your knee and up your thigh towards your ass, gripping a firm handful as he pulls you closer. nuzzling his nose into the side of your kneecap, he allows his lips to drag lazy, partially opened-mouth kisses over the delicate skin, his stormy eyeline flickering up to watch you. you could see, even through his bangs, that his gaze was heavily lidded, as if he were already enjoying himself. “So nervous. So adorable.” he purrs, tilting his head. his teeth are sharper than you anticipate when he pulls at the soft, sensitive skin on your thigh with them, and you let out a whimper. “But these pretty, little sounds you make are oh-so tempting. If I were any less of a man, I would have to fuck you out right here, until you could no longer stand up, and leave you crumbled on the floor oozing cum.” Kaeya is hyper aware of the flash of anxiety over your features, and the sight causes him to swoon. he likes that he can frighten you. “Is that thought a scary one? To know that I’m restraining every primal urge I have to impale you on my cock and let you break on it?” when you, wide eyed and trembling, nod, he grins and places another gentle kiss over the bite mark he’d left on your leg, smearing saliva into the grooves. “Mm, but I wouldn’t do that to you, little sister. That would be far too easy a task, to break your little mind quick and hard. I’d like to see, instead, you have a little taste of me and then spiral into madness and lust all on your own, until your virgin cunt weeps whenever you so much as stand next to me in this very cathedral. You’ll beg me to fuck you into oblivion, and when you’re finally so desperate that salty tears stream down your cheeks, I will be the gentleman and give you exactly what you want. Sounds fun, doesn’t it?”
your heart pounds hard against your rib cage and you try to take a deep breath, but it’s almost as if every gulp of potential oxygen escapes you as Kaeya’s head disappears under your skirt, to smash his mouth against your netherlips. scrambling, your knees tuck inward, although they do little to push him out, snagging against his powerful chest, and you try to shove at the bobbing, round bulge of the crown of his head underneath your dress. “K-Kaeya!” you croak; your mind floods with the brand new ecstasy of being pleasured upon the swirling of his thick, skilled tongue over your swelling clit.
“Shh, now,” he purrs— his baritone slurred against your sex as he laps at you. using his dominant hand, planting it on your core so his fingers spread your folds and expose your bundle of hyper-sensitive nerves to him, he busies the other by snaking it up to clamp against your mouth again. “You’re in a church, remember?”
mewling against the warmth of his palm swaddled in fabric, your eyes are wide, staring up into the cavernous, vaulted ceiling as his mouth works between your legs. tongue and teeth teasing your button, until those wide eyes of yours begin to cross, your lashes fluttering. taking in every new, electrifying sensation.
“Aren’t you just so easy to play with?” Kaeya grunts, shifting on his knees to get a better angle, his tongue delving downwards to tease your virgin hole, that spasms and clenches in response to his threat of invasion. he gurgles a happy sound. “Sensitive and shy, but your body knows best, little sister. You want to cum, no?”
embarrassed, you let out a muffled, uncertain: “Y-yes…!” against his hand, but both of yours are working to grasp handfuls of your skirt and pull it back to see exactly what he’s doing down there. you can’t help yourself— you let out a breathy and flustered whimper upon seeing his face between your legs, a quarter of it shiny with your slick, and his tanzanite eye nearly closed. he looked drunk off your taste, a subtle red tint blessing his cheeks, but when he catches you looking, his lips spread into a knowing grin.
“That’s a good girl, just give into it.” Kaeya pulls back only enough to speak, his warm breath fanning your vulnerable core with each word, and watching how your hips twitch towards him. “Needy thing. Like an animal. Don’t worry, sweet girl. I’ll see to it that you’re teased and pleased until your legs give out. After I’m done with you today, you’ll only dream of what else I can and will do to your fragile, little body once I return to Mondstadt.” he pauses for a moment, before he adds in a playful, amused whisper, placing a kiss on your inner thigh, “I think I’ll enjoy coming home to see how willingly you offer yourself up to me next time.”
