Concupiscence

Summary:

Kaeya investigates a greenhouse looking for evidence of a pharmacy owner's ties to the Treasure Hoarders, but what he stumbles into instead is a hefty dose of a potent aphrodisiac. Of course, the greenhouse's owner chooses that time, of all times, to show up—and oh no, he's hot.

Kaeya's libido reacts as one might expect, and a deal is struck.

Notes:

This fic has been around in one form or another, whether in concept or as an outline or a WIP, for almost two years now. I originally conceived of it for the "Aphrodisiac" prompt of the first Baizhu Week in 2022.

A variety of things from life events to writer's block to being more interested in other fics has kept me from completing it until now, but I kept it in my WIP folder and touched up the original concept over time as we learned more about Baizhu. Now it's finally seeing the light of day, and although the implementation diverges a fair bit from the initial concept two years ago, I'm extremely pleased with how it turned out. Hopefully you will be too!

Kaeya is trans in this fic, and sexual terms traditionally associated with women are used (by him) for his anatomy. I'm trans myself and comfortable with this, but if you have sexual contact with a trans person please ask them what terms they would prefer be used for their anatomy so you don't risk triggering dysphoria.

P.S. I'd like to thank this picture (NSFW) for being the most insanely hot Baizhu picture I've ever seen, and opening my eyes to the possibilities of vine tentacle Baizhu. It was a large part of the inspiration for this fic. I'm not sure it ever progressed past the WIP stage, but it lives rent-free in my head regardless.

(See the end of the work for more notes.)

Work Text:

Kaeya is, strictly speaking, in Liyue on official Knights of Favonius business—but that’s never stopped him from following an unrelated lead before, and it’s certainly not going to stop him now.

He’s only in Bubu Pharmacy to stock up on some routine first aid supplies, but really, nobody can blame him for getting curious when he spots several Treasure Hoarder insignias lying beside a map on the other side of the counter, now can they? And if he deliberately makes a large enough purchase that the little girl behind the counter has to go to the back rooms to fill his order, leaving the map wide open for a roving eye to scrutinize, that’s not really anybody’s business but his own.

Kaeya’s familiar with most branches of the Mondstadt and Liyue Treasure Hoarders, but he’s not familiar with the camp marked on the map. That alone would make it worth checking out, but why would Liyue’s most reputable pharmacy have dealings with them? Now that is a mystery worth looking into, even at the cost of his precious free time.

He memorizes the location, replaces the map, and thanks the child with a generous tip before depositing his goods at his inn room and setting directly off for the camp. It’s not too far north of the Harbor, past a cluster of abandoned houses and edging into the wilds of the Guili Plains. Just how have a group of Treasure Hoarders remained undetected so close to the city? No doubt Diluc would have something scathing to say about the efficacy of the Millelith.

But as it turns out, there are no Hoarders there at all. Just a single large, glass-walled building, overflowing with greenery inside.

A greenhouse in the middle of nowhere is almost more suspicious than a camp of Treasure Hoarders. Bandits infest every nation like fleas, but only the truly well-connected and well-endowed have the means to set up such an expensive building and just leave it unattended in the middle of nowhere. The large, clear glass panes could each feed someone for a week if sold, and the plants inside are likely worth quite the sum of mora if someone went to the trouble of setting this place up for them.

It’s likely full of illegal substances, then, and owned by someone powerful enough that the locals know not to mess with it.

Fascinating.

He scopes the place out from a few angles until he’s satisfied there’s nobody inside, then strolls casually up and lets himself right in. There’s no lock—why would there be, as easy as it is to break through the walls?—and no traps spring as he eases himself gently through the front door.

Rows of raised garden beds greet him inside, each bursting with abundant growth. The colors and patterns are dizzying; it’s incredible how many plants have been packed into the moderately-sized building. Most of the actual greenery seems to be on the outside, with more exotic flowers and herbs populating the inner rows; there are even a few water tanks filled with various algae and seaweeds, with specialized tools Kaeya can’t make heads or tails of neatly boxed up nearby.

It’s snazzy, to be sure, but all in all the place is rather boring compared to what he’d expected. His knowledge of plants is admittedly limited, but can identify most contraband substances and hasn’t seen any. Maybe the place is just a waste of time after all.

He turns on his heel and strides for the exit, but something in a nearby potted plant catches his eye on the way: a glimmer among the dirt. He kneels to inspect it and finds a thin layer of Treasure Hoarder emblems mixed in with the topsoil.

Strange.

Rooting around in the pot with nearby gloves and spade turns up nothing else of interest—no spooky severed body parts secretly fueling the plant’s growth, no hidden Treasure Hoarder goods. It’s just...a sapling, that he’s undoubtedly stunted the growth of with his curious search.

He pats the side of the pot. “No hard feelings, yeah?”

Predictably, it doesn’t respond.

He peels the gloves off, shakes them free of dirt, and walks headfirst into a large, sticky bloom lurking behind him.

Plants aren’t capable of independent thought so it’s a little ridiculous to feel like he’s being mugged in a dark alley, but it’s his first thought nonetheless. Sticky nectar and pollen cling to him as he closes his eye, tries not to breathe, and scrubs at his face with his sleeve. It just makes things worse, smearing across his skin in a thin coating, ruining his fur ruff, and clumping his hair together in damp strands.

Ugh, just how wet can a single plant be?

He squints, trying to make out where the tanks of aquatic plants were. Maybe he can wash himself clean—ah, there! He staggers for the nearest and promptly trips over the discarded gloves and spade.

“For fuck’s sake—” The expletive spills out naturally as he throws out his forearms to catch himself on the tiled pathway, and his body is shocked into taking a heaving breath of air. Cloying sweetness makes its way through his nostrils, the scent thick enough to make him choke. Nectar-coated hair swings into his mouth, and although he spits it out immediately, the sweet taste lingers on his tongue.

He abandons dignity and crawls for the nearest tank, though it seems leagues away now as his limbs begin to feel weak and sluggish. With each staggered placement of hand and knee the room grows oppressively hotter, and before he’s gotten ten paces he feels like he’s boiling alive in the muggy heat of the Golden Apple Archipelago. Sweat drips down his back, and he pauses to wrestle off his fur ruff and cape so the remnant stickiness doesn’t trigger further reactions—as well as simply to relieve himself of some heat.

It’s only as he’s reaching absentmindedly for the laces of his breeches that he realizes he’s wet between his legs as well, and it is decidedly not sweat. He didn’t intend to remove his pants—as tight as they are, they’re his only lower layer, and he’d really prefer not to literally be caught with his pants down. But the sheer amount of wetness is concerning—he takes herbs that prevent menstruation as part of his transition, and if they’ve stopped working, he needs to know. So he gives in and peels his breeches off, panting heavily as heat spreads through his body.

An exploratory poke at his nether lips sends a shock through his core and results in the most undignified combination moan and squelching noise he’s ever made in his life. His soaked cunt contracts at the touch and sends a gush of slick arousal to coat his fingers. Not blood then, at least, which is good, but—

He doesn’t get this wet, especially not while dealing with medical emergencies. What in Barbatos’ name is going on?

He brings his thumb up to swipe over his clit, finding it as hard and swollen as if he’d been through an hour of foreplay. His head spins at the touch and he pants hard, chest heaving as he struggles for air. He reaches up to unbuckle his choker with his free hand, tugging it desperately open for easier breathing.

His head lolls back as he touches himself, and a drip of drool falls from his suddenly over-wet mouth. He swallows around nothing, tongue feeling thick and heavy as the nectar causes even his salivary glands to work overtime. He’ll just—he’ll just get off real quick. Yeah. That’s it. He’ll take care of this incessant itch under his skin, this horrible emptiness, and after that, he can—

What was he doing again? It’s not important, probably.

Fingers dip into his entrance and slide in knuckle-deep with ease, prompting a groan. He cups his chest with his other hand, pinches at his nipple. A few deep thrusts inside and he pulls his fingers out to suck on them, licking himself clean and savoring the flavor of something other than saccharine plant goo.

He spreads himself open more fully and begins fucking himself on his fingers in earnest. It’ll take longer this way, it’s not as easy as with clit work alone, but the need to be bouncing on a cock is strong, and this is the closest substitute he has. It holds the thrumming need in his body at bay, even if it doesn’t fulfill it. He just—he just needs to come, that’s all. Then he’ll be fine.

His hand begins to cramp from the angle, and he’s forced to use his other hand to prop himself off the floor for better access. Archons, he wishes he had more hands; he wants to be fucked, to fondle his chest, to suck on something. A nipple or a nice, thick dick would be preferable, but fingers will do in a pinch, he’s just limited by the bounds of the human form. If only there was someone here to fill a few of his holes, he could cover the rest—

“Oh, dear. I see you’ve had a run-in with my Rhododendron venerem.”

Kaeya lifts his head and blinks through blurry vision to find one of the most gorgeous people he’s ever seen crouched down beside him. Long, luxurious green hair, a piercing gaze over glasses, and so much skin on display. He reaches out for their exposed belly, unthinking, only to have his hand slapped away.

“I’ll thank you to keep your hands to yourself. I’m not the type of man that sells his body to strangers, much less thieves. And even if I was, I’m quite sure you couldn’t afford what I would charge.” The man stands and begins walking away.

“M’not—I’m not a thief,” mumbles Kaeya, head falling back with a groan. “Jus’—wanted to make sure you weren’t working with—mm—with the Hoarders.” He works his thumb over his clit, inhibitions fallen away with the effects of the plant. The man has already seen all of him. He just needs to come, and then he can think clearly again and find a way out of this.

The man pauses. “The Hoarders? Oh, I am working with them, in a manner of speaking.” His figure sharpens as he walks back toward Kaeya. “I treat their ailments same as any other, but I won’t take their ill-gotten money. In exchange for medical care, I make them promise to turn over a new leaf. They give me their membership tokens as a sign of their sincerity. They’re excellent for drainage in potted plants; something about the unique alloys used makes them incredibly effective as an antimicrobial agent.”

He kneels beside Kaeya again and lifts something to his lips. Kaeya clamps his mouth shut, breathing hard through his nose as he works at his clit.

“Oh, quit being difficult. You’re writhing on the floor half-naked and delirious. If I wanted to hurt you, I could just hit you over the head with a shovel. This will prevent heart issues if you’ve overdosed, though I’m afraid it won’t help with the arousal. Besides, you look like you could use a drink.”

Well. The man does make some good points. Kaeya allows him to place some sort of rubbery leaf in his mouth, chews it up, and washes it down with a hearty drink from the jug the man is holding. He’s overeager and spills quite a bit down his front, but gods know he could use a good wash right now anyways.

The man puts the jug down and leans against the nearby workbench, crossing his arms and scrutinizing him over the rims of his glasses. Kaeya shudders, feeling exposed and vulnerable, but unwilling to stop grinding against his palm for relief. He does at least recover the presence of mind to rearrange his legs and arms for a bit of modesty, however.

His mysterious rescuer’s eyes sweep across the greenhouse, taking in the trail of discarded clothing. His gaze stops at Kaeya’s belt, lingering on the vision. It’s close enough that Kaeya could call on its power if the man made a move to take it, but he does no such thing. Instead, he cocks his head in thought.

“From Mondstadt then, are you? Your vision casing seems a bit damaged, but it’s distinctive regardless.”

Kaeya swallows a bitter laugh, swaying with dizziness. He can’t actually respond with “Sorry, but no, I’m actually the last scion of a kingdom destroyed by the gods,” now can he?

“Guilty as charged,” he says instead, skimming his entrance with his fingertips to keep the horrible arousal at bay. He does his best to keep his speech even, but it’s taking him longer than usual to string words together. “Member of the Knights of Favonius, actually. Though I’m aware this incident hasn’t painted me in much of a chivalric light.” Perhaps if the man knows he’s a Knight he’ll go easy on him to avoid a diplomatic incident.

No such luck.

“Oh? I wonder what the Knights would think to know a member of their ranks was snooping around like a common criminal.” The man laughs, a surprisingly dark and mischievous chuckle for someone appearing so elegant. “And I do believe I have a spare Kamera in the storage shed, too. I’m sure I could take some photos your boss would be extremely interested in...”

Kaeya almost laughs at the threat. Jean would tear him a new one for breaking and entering, but it’s not like she hasn’t seen him naked before in the showers. Still, he doesn’t relish the thought of having to explain himself to her, so he puts on a show of acting afraid.

“I swear I didn’t mean any harm, sir! Just let me take care of myself and I’ll be out of your hair.” He draws his lips up into a practiced pout and bats his eyes as innocently as he can muster while knuckle-deep in his own cunt.

The man shakes his head. “Unfortunately for you, I do have work to do in the greenhouse today. I can’t throw you into public and expose others to this shameful behavior, but neither can I have you moaning in the corner while I try to garden. What to do with you...hmm.” He paces around Kaeya, sizing him up like a cut of meat at a butcher’s, then snaps his fingers. “Ah! I have a proposal. I am willing to assist you through your altered state, in exchange for an agreement to ship me some local specialties from Mondstadt. Wolfhook and Cecilia primarily, though there are some rarer ones I can provide you with images of if needed. If you accept the deal and fail to provide the goods, I will inform the Knights of your deviancy.”

Kaeya almost giggles, tipsy and light-headed on the drug as he is. The Knights are well aware of his deviancies. But if ‘assistance’ means what he thinks it does, he won’t turn down an offer that gracious. He’s aching to be filled by anything or anyone right now; the fact that this guy is drop-dead gorgeous is just a happy bonus. And it’s not like he doesn’t pass native plants on the regular while doing his duties as a knight.

He inclines his head in agreement. “Well now, I can hardly disagree, now can I? You have me at a disadvantage, Sir...” He frowns. “Actually, I don’t think I got your name.”

“Baizhu, boss of the Bubu Pharmacy in Liyue Harbor. You can have the specialties sent there. Now, I realize conventional notions of consent are a little skewed in this scenario, but for what it’s worth, can you confirm you’d like me to aid you with your sexual frustration as per the terms of the aforementioned deal?”

Kaeya laughs. “Oh come on, a man as gorgeous as you doesn’t need to drug me to pique my interest.” Seeing the man frown, he rushes to clarify. “Yes. Gods yes. Please touch me. I’m wetter than an Oceanid right now and I’m going to be every bit as cranky if I don’t get off soon.”

“Hmm, well. I won’t be touching you personally. As I said, I’m worth more than you could hope to pay.”

Kaeya can’t help the displeased whine that spills from his throat. He needs filled, and fast!

Baizhu laughs that dark laugh again. “Not to worry. I’m a solution-oriented individual.” He sinks into a sitting position in front of Kaeya and makes a hand motion to indicate that he should spread his legs. “Open wide. I can’t help you if I can’t access you.”

Kaeya parts his legs and withdraws his slick-soaked hand, baring himself to Baizhu’s gaze. Shame is a secondary concern now, with every inch of his body tender and aching with the need to be touched.

Baizhu reaches out and for a moment Kaeya dares to hope he’s going back on his ‘no touching’ policy. Instead, there’s a bright green flash as the man’s vision activates, causing vines to spring forth and wrap around Kaeya’s legs. They dig lightly into the muscle spread him wide, and he winces at the teasing touch of air to his swollen clit and spread hole.

“Calm down, I’m not going to hurt you. I just needed a better look at what I was working with.” Baizhu leans in to look closer, and Kaeya throbs under the attention.

“Oh, dear. Quite engorged, I see. You seem to be extremely sensitive to this particular nectar. I’d love to experiment on you sometime. How long had you been here before I found you?”

Kaeya swallows, trying to think straight through the dizziness and need. ‘I’d love to experiment on you’ shouldn’t be such an arousing phrase.

“It’s hard to tell. Things went fuzzy when I walked into the plant, and they’re still a bit hazy if I’m honest. But it was only a few minutes, I think.” He catches sight of a tent forming in Baizhu’s trousers and tries extremely valiantly not to think about sucking that cock and riding it. (He fails spectacularly.)

Fascinating. I’ve never seen someone react to it so quickly. Not that I’m usually watching when it’s used, though I’ve experimented on myself to learn more about how it works, of course.”

The image of Baizhu, alone in bed and groaning as he fucks his hand, comes to mind unbidden. Gods, his cock is probably as pretty as the rest of him. Kaeya groans and reaches down to touch himself but another vine catches his wrist, pinning it to his thigh. He whines, prompting a coy laugh from Baizhu.

“Hands out of the way, I need to be able to see what I’m doing. Now, do you have any objections to these going in particular orifices?”

‘These?’ Oh. He means the vines. A fresh wave of arousal pulses through Kaeya’s body at the thought. No, no objections to that. Any hole will do, really.

Baizhu laughs again, and Kaeya realizes he’s answered out loud. “Any hole, hmm? Do be careful to watch your language while visiting Liyue. Contracts are only as good as the language used to craft them. With that answer, I could shove something up your nose and call my job done.” At the face Kaeya makes, he holds up his hands reassuringly, causing the vines to shift slightly. “I won’t, I won’t! I’m a medical man through and through, I would never leave a patient untreated. Just a friendly word of advice. Not everybody holds themselves to my standard of morals.”

Kaeya only breathes heavily in response. It’s getting hard to talk now, the heat crawling through his body stifling his higher mental functions quite effectively. His eyelids droop, heavy and leaden, urging him to surrender and be taken. He forces a nod out and bucks his hips impatiently.

“Oh, all right then.” Baizhu’s amusement is evident in his voice.

The bulbous head of a vine presses itself to his front entrance, dripping with some kind of thick fluid that mixes with his own. He’s breathless for a glorious moment of anticipation, waiting, waiting—and then the vine slips inside, the thick, textured head bullying its way over his sweet spot, and he tips over a dizzying precipice of almost painful sensation and squirts harder than he ever has in his life—directly onto Baizhu’s curious face.

He shakes, clenching out aftershocks around the thick bulb, as Baizhu scowls and rubs his glasses clean with a cloth from his pocket.

“Really now, you didn’t think to warn me?”

Kaeya lets out a chuckle that’s even breathier than usual as he pants hard and struggles to collect his thoughts. He can think more clearly now, but he’s no candidate for the Akademiya just yet; the act of forming a complex sentence seems as daunting as writing a thesis. Still, he struggles valiantly onward.

“It’s not exactly normal for me, I don’t even—hah—I don’t do it that often, much less that enthusiastically.” He shakes his head to clear it. “Profoundest of apologies, my good doctor. Consider it a testament to your skill.”

Baizhu lets out a quiet huff as he puts his glasses back on. “Well, did it satisfy you, at the very least?”

Assessing his physical and mental state, Kaeya is disappointed to discover that the answer is a resounding no, and that the continued presence of something inside of him is only heightening his arousal. He squirms, grinding down against the bulb, and gives the closest thing to a helpless shrug that he can while still being gripped by vines.

The intention must come across, because Baizhu sighs and nods. “As I suspected. Your sensitivity likely means it will take more work than usual to get the aphrodisiac out of your system. Not to worry; I have plenty of helpers, after all.”

Kaeya barely glimpses the tiny smile on Baizhu’s face before the vine in his cunt begins thrusting and another slimmer one prods at his ass, circling his rim and dripping thick fluid. It massages at him, relaxing his entrance, but his attention is diverted by two smaller ones that tug gently at his nipples. He looks at his chest just in time to see one unfurl itself into a star shape. Curious, what is it—oh.

The vine latches on to his nipple and begins to expand and contract in suspiciously coordinated motions, secreting a small amount of moisture as it does so. It makes a lewd squelching noise, almost as loud as the not-insignificant noises of his dripping pussy being vigorously fucked into, but most importantly it very accurately mimics the feel of a real mouth sucking at his chest. Kaeya throws his head back and moans.

Baizhu takes advantage of his open mouth to shove another vine in. It prods at his throat only briefly before sliding deeper inside, and Kaeya closes his eyes and surrenders to the sensation; lets his throat go lax and tries, desperately, to steady his breathing through his nose. It’s saccharine and floral, filling his airways with a cloying musk that he can’t escape, nothing like a real dick in taste and only bearing a passing resemblance in texture and shape—and yet.

And yet.

He’s eager for it all the same, swallowing around it greedily as his head lolls back in a needy, drugged haze. His body relaxes as the vine’s secretions make their way through him, and he finds himself desperately trying to shove himself down on the one probing at his ass, to catch that teasing head on his rim. Baizhu makes a disapproving noise and the vines hold him in place more firmly, preventing him from simply spearing himself open while he’s further prepped. He surrenders, closing his eyes and reveling in the dizzy pleasure of being rocked to and fro as he’s spit-roasted by vines.

Time passes like thick honey, and he’s startled out of his blissful reverie when Baizhu makes a pleased noise and finally, finally shifts the thick bulb of the vine inside of his ass. The first bulb almost hurts, wide as it is, but when it slips past the inner ring of muscle further in and Baizhu begins to feed another into him, it strikes Kaeya that they’re not unlike anal beads—and those, he knows he can take. (And love, and beg for more of.)

And beg he does. At least, he tries.

Baizhu stops after feeding only a handful of the egglike bumps into him, and Kaeya’s nostrils flare in disappointment. He forces his eyes open and turns to Baizhu, struggling to speak around the vine in his mouth as he wriggles his ass down as obviously as he can against the vine.

“M’—ah, pl—hahh—” He’s cut off by a long groan as more vines wrap around his limbs and hoist him into the air, hips held high, blood rushing to his head and making him dizzy as he’s hung in an arc. Baizhu must be managing more than ten vines by now, all dedicated to holding Kaeya in the air securely and filling his various holes. His fine control over his vision is incredibly impressive—and useful. It makes Kaeya wish his cryo vision was useful for more than the occasional temperature play.

Saliva drips down his cheeks as he continues to beg, mingling with the remnants of the sticky nectar to make a mess of his face. The vine in Kaeya’s cunt thickens and fills out with ridges as it thrusts, curving to rub over his sweet spot with each movement. The ones imitating mouths withdraw and are replaced with smaller ones that curl around his nipples and pluck at them in a pizzicato frenzy. His ass is pleasantly full, clenching greedily around the textured bulbs that rub against the vines in his pussy through his stretched inner walls.

It’s a lot, and still not enough. Tears leak from the corners of his eyes as he lets out a frustrated whine and makes eye contact with Baizhu, silently pleading with him to do something, anything, to finish this off and rid him of the burning heat that threatens to boil him from the inside out.

Baizhu smiles wickedly, mischief dancing along his lips, and steps closer. His warm breath ghosts along Kaeya’s ear and his hand brushes across Kaeya’s skin as he sweeps damp hair out of Kaeya’s face, careful to avoid the copious saliva leaking from his overfull mouth.

“Well.” He pauses, drawing out the torture. “Maybe just a little touch.”

Fingertips brush the smaller vines aside and dance over Kaeya’s nipples, sending a bolt of pleasure along his spine. The heat in Kaeya’s body begins to gather in his core, promising imminent relief. Kaeya lets out a heaving breath and almost chokes but Baizhu doesn’t withdraw the vine, doesn’t relent in his touch.

Hands trail over Kaeya’s sides, squeeze his hips, tug at his nipples. He twists in the air, squirming under Baizhu’s teasing. And just when Kaeya thinks desperately that he can’t possibly take any more, that surely this will be the end of him, that he’s going to literally die of horniness while being fondled midair by the prettiest stranger he’s ever seen in his life—the vines in his cunt and ass shove impossibly deeper and fill him with what feels like more cum than a human could produce in a month. His abdomen puffs up as he shudders under Baizhu’s touch, burning up inside, and he allows his body to be played like an instrument by Baizhu’s skilled fingers, following the crescendo of pleasure finally—finally! to an explosive finale.

He sobs, shudders, and soars for one glorious moment. All goes quiet until the only thing he can hear is the ragged sound of his own breathing and the constant drip, drip, drip of fluids from his holes.

Kaeya’s limp body is lowered carefully to the floor, head still spinning from the effects of the suspension, as he clenches down hard. Copious amounts of viscous plant goo gush from his cunt and ass and he grimaces, letting out a hoarse, undignified sound of disapproval as he’s glued to the floor in a slowly growing puddle. (He tries to get out, really, he does, but his entire body is exhausted and weak, and he can barely drag himself upright, much less to a different location.) Eventually, he just gives up and lies in the shameful puddle, pouting.

He thinks he’d stay there forever if it weren’t for Baizhu reappearing seemingly out of nowhere and thrusting not one, but three towels at him. The sight of them gives Kaeya the impetus he needs to groan and begin lessening his misery. He hauls himself to a clean patch of walkway between garden beds and begins toweling off briskly, starting with his absolutely filthy face. He sneaks peripheral glances at Baizhu from time to time as he goes, curious as to what the man plans to do now that the emergency is over.

Baizhu hasn’t stopped watching him. Kaeya flashes him a smile; now’s not the time to get shy about his nudity, after all. He’s already seen everything.

He clears his throat and tries speaking. It’s much easier to fall back into his usual speech patterns now, words coming quicker to mind as the drug fades from his system.

“I’m not going to run off with your towels, you know. In fact, I’ll even mop up and do the laundry, though it may need to wait until after I’ve had a proper soak in a river. Call it a token of Mondstadt’s esteem for your fine establishment.”

Baizhu ducks his chin in barely-there laughter. “Not a token of esteem for my horticultural aptitude? And here I thought I’d impressed you with my botanical know-how.”

Kaeya switches towels, his voice regaining some of its usual charm as he bats his eyelashes in Baizhu’s direction. “Oh, you certainly did do that. But if I’m to thank you for something so...personal...I’d need to thank you with something personal in turn, if you catch my drift.”

Baizhu tilts his head with a small, coy smile. “I believe I do. And I’m not opposed to the idea, even if we are doing this entirely out of order. But I’m afraid it’s all business today, I really do need to tend to my plants. Many people are depending on them.”

Kaeya reaches for his pants before changing his mind and wrapping the third towel around himself. “Give me one moment—” A fresh glob of plant cum slides down his thigh, and he winces. “Uh, five moments, maybe—to get cleaned up in the river, and I’ll help. I do owe you.”

He does not add “After all, you fucked me so well that I’m having trouble standing.”

He can barely hear Baizhu’s reply over the clatter of garden tools being pulled from a box nearby. “I’ll hold you to that, mystery knight. Though I hardly think there’s a point in taking a bath before gardening.”

Kaeya glances down at his plant-cum-streaked legs and politely disagrees.

“It’s Kaeya. Kaeya Alberich. And I’d like to be able to wear clothing while gardening, and my clothing is not going on over...” he gestures at the sticky mess of his body. “This.”

Baizhu arches an eyebrow. “Well don’t say it like that, or you’ll tempt me to rope you into helping me in the nude. A strapping young helper, sweaty, muscles bulging as he picks up a sack of soil...mmm. I’m tempted. You’re quite easy on the eyes, you know.”

Kaeya snorts, falling easily into the familiar patterns of flirtation. “I’m sure I’ll be even easier on them after gardening, when I oh-so-sneakily invite you to take a bath together so I can return the favor from earlier.” He waits a carefully calculated one and a half seconds. “Oops, did I say that part out loud?”

Amber eyes fixate on him, and Baizhu’s expression grows serious. “You know you don’t owe me anything beyond what we agreed upon, correct? I am truly not trying to take advantage of you, Sir Kaeya.”

Kaeya thinks of Anna back in Mondstadt, dutifully taking her strange remedies even as others dismissed her foreign doctor as a quack. Well. He’s certain enough now of just who’s responsible for that miracle cure.

He tosses a smile back at Baizhu as he heads for the exit.

“Doctor Baizhu, I know you’re not taking advantage of me. But with skills like yours, who’s to say I’m not eager to take advantage of you?

He basks in the warm glow of Baizhu’s answering blush as he sets off for the river.
