He's spent centuries as a spirit, a familiar to a witch who has only recently released him from his contract. She also encouraged him to use his human form more.

Though 'encouraged' is a nice way of saying 'cast a spell to change him to his human form without a way to change back.'

It's been tough, but Diluc has his new master to help him out.

Kaeya tries to insist that he isn't Diluc's master, his skin flushing even darker every time Diluc refers to him as such, but Diluc doesn't know how else to contextualize what Kaeya is to him. Kaeya takes care of him, giving him food and shelter, and he's so patient with helping Diluc get used to his new form.

It's been several months since Kaeya took Diluc in when Diluc starts feeling... off.

His first thought is that he's coming down with something, but after giving himself a check-over, Diluc realizes the reality of the situation: his heat has come.

Normally he would have Alice cast a spell to suppress his heat, and then hole himself up somewhere soft and dark to ride the worst of it out. But Alice isn't here, and Kaeyaisn't a witch.

Kaeya gave him a room when Diluc moved in, so he decides that there will have to do. He collects all of the bedding from around the apartment and uses them to turn his bed into a nest.

As he's rifling through Kaeya's room for extra bedding, he comes across one of Kaeya's hoodies, and something compels him to pull it on. It smells nice. Really nice. And it makes Diluc feel warm and safe. So he keeps it. Kaeya won't mind, right?

As soon as Diluc is nestled amongst the blankets and pillows on his bed, his heat properly hits him. He kicks off all his clothes, overheated, but then puts Kaeya's hoodie back on, unable to take not being surrounded by the human's scent.

He quickly finds himself in a pathetic state, sprawled out on his bed with the sleeve of the hoodie held to his nose and his fingersstuffed deep inside of his pussy. Kaeya's scent is overwhelming, prompting Diluc to shove his fingers in even deeper.

It's entirely different in his new form. He's not even fully sure what he's doing, he just knows that it feels good, especially when he crooks his fingers like--

Yes, just like that. Diluc whines, arching into the sensation.

He doesn't mean to think about Kaeya while he's doing this, but it's almost impossible to avoid when he's so wrapped up in Kaeya's scent. A mix of soft, freshly fallen snow, and ozone; the charge before a storm. It's addicting. Diluc can't get enough of it, mushing his face against his sleeve while he pumps his fingers.

Soon the position isn't enough, and Diluc rolls over, lifting his ass into the air with his tail pointing straight up, presenting himself for a Kaeya that isn't thereas he plunges his fingers back into himself and starts to fuck himself on them.

"Kae," he moans, rubbing his cheek against the soft material of Kaeya's hoodie. The way that his scent mingles with Kaeya's, strengthening that charged ozone scent with Diluc's warm smoky scent, and fuck is it maddeningly wonderful. Diluc mewls, closing his eyes and fucking himself faster.

"Kae... Kae please..." Diluc's brain is fuzzy with his heat, and the only thing he can think of is Kaeya and his large, lithe hands, touching Diluc all over.

"I need it," he whines, clinging to the pillow below him. It has Kaeya's scent too, and Diluc shoves his face against it, breathing in deeply and getting high on his master's scent.

"Master Kaeya, I need you," he whimpers. "Need you so bad..."

"Diluc?"

Diluc's head snaps up, and he looks over his shoulder to find his worst nightmare; Kaeya standing in the doorway, staring at him.

"I thought I locked the door," Diluc says weakly.

"It was open," Kaeya replies, looking dumbfounded. "Diluc, what--"

Diluc throws a pillow at him. It only just nearly misses Kaeya's head, the human ducking out of the way at the last moment.

"Go away!" Diluc hisses, mortified. Gods, Kaeya can see everything. Diluc presses flat to the bed, tugging at the hem of the hoodie and curling his tail around himself. "Don't look at me!"

"Luc," Kaeya says gently. "I'm-- I'm sorry, I'll-- is that my hoodie?"

"No," Diluc lies, even though it very obviously is.

"... right. And you definitely weren't calling my name just a few moments ago."

Diluc shakes his head, his ears flat against his scalp. Can this just beover already? Diluc wants to cry from embarrassment, and from the fact that his body won't let him remove his fingers from his cunt.

Kaeya sighs. "Look. If you really want me to, I'll leave. But if you want me to stay..."

There's a few beats of silence where Diluc can feel Kaeya's eyes roving over him, taking him in. He's torn between shrinking down even further, and uncurling to present himself.

"I'd like to take care of you, kitten." Kaeya tells him, his tone low and smooth. Diluc shudders, and his body decides for him, his hips and tail raising to present his soaked pussy for his master.

"Please," Diluc murmurs, even as he hides his face in shame. "I need you..." His fingers, still buried inside of him, splay to stretch his hole open, showing Kaeya just how loose and wet he is. "Here."

"Fuck, kitten," Kaeya groans, and then the door shuts, and Diluc feels Kaeya's weight settle behind him on the bed.

"Awfully nice nest you have here," Kaeya tells him. Diluc's chest glows with praise, and his tail swishes happily. "Yeah? You like it when I praise you?"

"Shut up," Diluc grumbles. Kaeya's hands settle on his bare ass, and Diluc gasps, arching into it. Kaeya's touch is electric, sending shivers up Diluc's spine as Kaeya gently kneads his ass.

"Oh, so you're gonna be a bratty little kitty, huh?" Kaeya teases. "Guess I should've seen that one coming."

Diluc grumbles, not wanting to confirm or deny that. Kaeya tuts.

"Well, I guess I'll just have to teach my little brat a lesson, hm?"

Diluc isn't sure what Kaeya means, but then Kaeya's thumb is brushing over his folds, and another mewl leaves Diluc."So cute," Kaeya murmurs. His thumbs part Diluc's folds, exposing his slick, needy hole. Diluc can feel Kaeya's breath against him, and it makes him shiver.

"Kaeya," Diluc manages to say, though he's unsure if it's a warning or a plea.

"I've got you, kitten." Then Kaeya's tongue is laving over Diluc's sex. Diluc startles, clenching around nothing. Kaeya groans, licking at him again. "Fuck, Luc, you taste amazing."

Diluc hides his face in a pillow, trembling as Kaeya continues to lick at him. He's never felt anything like it.

Kaeya eats him out with a practiced ease, one that makes something possessive and jealous burn in Diluc's gut. Who else has Kaeya touched like this? Did he prefer how they tasted? The way they moaned? Would he rather be eating them out right now?

"Kitten," Kaeya says gently. "I can hear you thinking. What's on your mind?"

Diluc swallows thickly, debating telling him. Will Kaeya think that he's crazy? Too clingy?

"Are you mine?" is what his heat-clouded brain manages to ask. Diluc regrets it immediately, hiding his face in the pillow.How stupid of him to ask. Kaeya is his master. Kaeya belongs to nobody but himself.

But Kaeya hums in thought, rubbing his cheek against Diluc's ass in a way that distinctly feels like scenting. Like Kaeya is marking Diluc as his.

"Do you want me to be?"

Diluc trembles, clinging to the pillow and willing himself not to nod. He doesn't want to know what Kaeya's answer would be. He doesn't want Kaeya to let him down easy. He just wants to have Kaeya tonight, for as long as he can.

"Luc," Kaeya murmurs. "Answer me. Do you want me to be yours?"

"Yes," Diluc can't help but whimper. "Mine. Only mine."

Kaeya chuckles, low in his chest, and Diluc braces himself for the worst. But Kaeya only kisses the back of Diluc's hip and says,

"Then I'm all yours."

Diluc lifts his head to look back at Kaeya in disbelief. Kaeya meets him with a soft, warm smile, a look in his eyes like adoration, and Diluc whines needily.

"What does my kitten need?" Kaeya asks, even as he starts crawling up the bed.

"Kae..." Diluc turns onto his side, a hand coming up to grip at Kaeya's shirt. "Please." He's not entirely sure what he's asking for, but Kaeya seems to know.

Their lips meet softly, Kaeya cradling the back of Diluc's head and tilting him into it. Diluc can taste himself on Kaeya, and it just makes him leak more wetness between his thighs.

"Kae," he gasps against his master.

"C'mere, kitten." Kaeya reaches between Diluc's legs, hiking one over his own thigh. His fingers find Diluc's pussy once more, and Diluc gasps as two long, slender fingers slip inside of him.

"Good boy," Kaeya purrs, gently feeling out Diluc's walls. "Is this what you need?"

Diluc nods deliriously, writhing on Kaeya's fingers. He's trying his best to ride them, but between his inexperience, the position, and the fog clouding his brain, the best that he can manage is awkward little rolls of his hips. Kaeya doesn't seem to mind though, murmuring encouragements and praises against Diluc's lips.

"Such a good boy for me. How long have you been holding out, hmm? How long have you been waiting for me to come satisfy you?"

Diluc whimpers, clinging to Kaeya's shirt. Normally he hates feeling helpless, but Kaeya holds him securely, making him feel safe.

"Please, Master," Diluc says. Kaeya's pupils dilate, leaving just a sliver of pale blue, and he tugs Diluc into a deep, fervent kiss. Kaeya's fingers pick up the pace, pressing right up against Diluc's most sensitive spot. He's sinfully skilled, drawing gasps and moans out of Diluc with ease.

"Just like that," Kaeya says against Diluc's lips. "Good boy. Such a good kitten for Master, aren't you?"

Diluc whines, nodding eagerly. Kaeya's fingers are driving him wild, and all he wants is to please his master.

He doesn't last much longer; Kaeya crooks his fingers just so, and Diluc keens as he comes, wetness gushing all over them both.

"Fuck," Kaeya groans, stroking Diluc through it. Diluc tucks his face against Kaeya's shoulder, shuddering as Kaeya draws out another squirt of cum from him. "Such a good boy for me, aren't you?"

Diluc whines as he starts to come down, breathing heavily against Kaeya. Kaeya gently pulls his fingers out, then holds Diluc close, rubbing at his back and murmuring soothing nothings into his hair.

"Doing okay?" Kaeya checks once Diluc's breathing has evened out.

"Mmn," Diluc grunts.

"Mm, you're full of surprises, aren't you kitten?"

"Shuddup," Diluc grumbles, though his tail trembles down to the tip, pleased.

Kaeya chuckles low in his chest, and before Diluc knows it, a purr is rumbling in his own chest.

"Cute," Kaeya murmurs, pressing a kiss to the top of Diluc's head. "Such a cute little kitten. Why didn't you tell me you were in heat?"

"Didn't wanna bother you."

"Oh, sweetheart, you could never. Well. Next time make sure to tell me, yeah? I'll clear my schedule and help you out."

Cautiously, Diluc lifts his head to peer up at Kaeya. "Yeah?"

"Of course. Anything for my sweet kitten."

They got there just in time for the cherry blossom viewings, and while it was extremely crowded, it was also magical. Plus, the crowds gave Jean an excuse to hold Barbara close to her, citing a need to not lose her in the jostling of the rough crowds. Barbara puffed her cheeks and complained about Jean babying her, but still tucked herself close to Jean's side and held her hand tightly.

Now, after a long day of exploring Inazuma city and all it has to offer, Jean is tired and sore. She knows exactly what she needs, and luckily the inn they're staying at is known for their hot springs.

"Hey," she says to Barbara, who is picking through the spoils of their shopping trip and sorting everything. "Wanna go check out the bathhouse?"

Barbara perks up immediately, nodding so enthusiastically that her twintails bounce. Jean stifles a fond chuckle and ruffles the top of Barbara's head as she gets up.

"C'mon, then let's get going."

They change into their robes and make their way down to the springs, pleasantly surprised to find that it's empty at this hour. They'll have the springs all to themselves, at least for the time being.

Once they're in the water, Jean sinks down into it with a contented sigh. Barbara giggles next to her, and Jean doesn't even have the energy toelbow her in retaliation.

"You really needed this, huh?" Barbara asks.

"Mm, a soak is perfect after a long day of walking."

"No, I mean... this. A vacation."

Jean peeks an eye open to look at her sister, finding her smiling fondly. "Yeah," Jean agrees. "I did. Thanks for making me take one."

"Mm, it's nothing. I just like seeing you happy."

A pang of affection hits Jean, and she has to reach up and stroke the backs of her fingers across Barbara's cheek.

"I like seeing you happy, too," she murmurs.

Barbara ducks her head, shy, and bumps her knee against Jean.

"I'm really happy," Barbara whispers. "Because I get to spend time with you."

Ugh, Jean can't take Barbara being so cute. She sits up properly and cups Barbara's face, tilting her into a short, sweet kiss.

"Jeanie!" Barbara complains once the kiss is over. She's bright as a tomato, and Jean can't help darting in to peck her on the lips again. "We're in public," Barbara reminds her in a hushed tone.

"There's no one here," Jean reminds her. "But you're right. I just couldn't help myself."

Barbara pouts adorably, but doesn't otherwise argue. She huffs and slumps against Jean's side, resting her head on her big sister's shoulder. Jean rests her cheek on the top of Barbara's head, and their hands find each other, fingers entwining.

They stay like that for a long while, just soaking and enjoying each other's company.

Eventually they have to get up, intending to rinse off so that they can change and go back to their room, but as Jean is standing, her towel slips, falling into her lap.

"Oh," Jean says. Normally she'd rush to cover herself back up, but it's just her and Barbara here. "Whoops."

"Your boobs are so big," Barbara comments, an adorable pout on her face. "What did you do to make them so big?"

"I just take after Mom more, I guess," Jean says, shrugging. "A lot of it just comes down to genetics."

Barbara frowns, looking down at her own chest. She's not flat by any means, but her breasts are far more modest in size compared to Jean's.

"Are mine ever gonna be as big as yours?" Barbara asks.

"Maybe, if you keep eating your vegetables," Jean teases.

"I always eat my vegetables," Barbara says seriously. Jean can't help but laugh, which only serves to make Barbara blush. "A-anyway. There has to be some way to help them grow..."

"Don't worry about it too hard." Jean reaches over to push Barbara's bangs away from her forehead, then leans in and plants a soft kiss there. "I think they're perfect the way they are," she murmurs.

Barbara blushes harder, ducking her head as she fiddles with her towel. "Yeah?"

"Yeah," Jean confirms.

"Do you wanna touch them?"

Jean glances around at the empty hot springs, knowing they're alone but wanting to double check. Once she's made sure it's just the two of them, she captures Barbara's lips in a tender kiss.

"Of course I do," she murmurs.

Barbara smiles, looping herarms around Jean's shoulders and kissing her back eagerly.

Jean tugs on Barbara's towel, making it come undone and drop into the water, revealing her little sister's perky little breasts.

"They're perfect," Jean reiterates, brushing her thumb over a pink nipple. Barbara gasps into her mouth and presses closer. Jean loses herself to the feeling, and soon she has a hand between Barbara's thighs, toying with her clit while Barbara softly moans against her.

It's definitely stupid to be doing this here, but at the moment Jean doesn't care. All she cares about is how cute her little sister is when she slips a finger into her.

Barbara clings to Jean, kissing her desperately as Jean finds that spot inside of her that makes her keen. Their breasts squish together, and Jean makes sure to rub her breasts against Barbara's, teasing her nipples and making her let out breathy moans.

"Jeanie, please," Barbara whines.

"I know, sweetie. I know." Jean kisses her again, pushing a second finger into her as she does. Barbara shudders, tensing up as her climax suddenly hits her.

Jean cradles Barbara to her chest as she comes down, rubbing her hand up and down Barbara's back. Barbara puts a hand on Jean's breast, squeezing it softly, and Jean chuckles.

"Like something?" she asks.

"Mhm," Barbara hums, then puts her mouth on Jean's nipple. Jean gasps, tangling a hand in Barbara's hair. Barbara sucks lightly on her breast, massaging the other one with her hand.

"Oh, sweetie..." At length, she nudges Barbara away from her breast, then cups her face in her hands. "Why don't we take this back to our room?" Barbara's eyes light up, and she nods eagerly. Jean pulls her in for one more kiss, licking into her mouth and making Barbara whine needily.

Once they part, they readjust their towels and go to rinse off and change. Jean watches Barbara with a fond smile.
