Chapter Text
You intently watched the red juice of the valberries drip from beyond the sieve into a small jar. Then, taking a moment, you inhale its sweet scent and note down your observations.
"Fresh valberries appear to be deeper in colour and sweeter in scent, in comparison to its preserved counterpart," you commentate, continuing to write down a smattering of numbers that represent the amount of vallberry essence you had obtained from the fresh berries.
Slowly you mixed the crimson liquid into the cooled beaker of chemicals, the cobalt colour of the concoction transforming into a deep violet. You hum satisfactorily, swirling the liquid around in the beaker before pouring into a vial and sealing it tightly.
You had been hard at work for the past week, hoping to create an optimised aphrodisiac. Despite mentioning the endeavour jokingly to Dottore, the idea intrigued you more than it should. The achievement of optimising what had initially been Dottore's creation also sparked a sense of determination within your ambitious heart. After all, you weren't merely Dottore's lover, you were also a loyal and intellectually talented assistant that shared a passion for experimentation with him.
"I've returned!" the familiar voice breaks your enthrallment with the aphrodisiac.
"I'm in here, Zandik!" you call out.
"What's this? Are you finally taking advantage of the new lab equipment," Dottore chuckles, entering the room.
You shoot him a welcoming smile. Dottore had extended the lab some time ago. Furnishing the new lab room with lavish benches, equipment and, of course, a small yet comfortable couch for when test results had to be waited on. Dottore immediately provided you access to the room. However, you avoided using it, afraid you would taint the new equipment.
Dottore skews his mask and coat aside, as per-usual, approaching the bench you were stationed at. You couldn't help yourself from leaving your experiment behind, throwing your arms around Dottore's neck and placing a kiss on his cheek. Dottore flushes for a moment before wrapping his arm loosely around your waist, taking the chance to hide his flushed face in the crook of your neck.
"You smell like valberries," he murmurs against your skin.
"What type of experiment are you conducting with valberries?" he asks inquisitively whilst pulling back from your neck.
You slowly lead Dottore to the bench presenting the vial of liquid and the experimental log you had been working profusely at. Dottore's hand remains at your waist, eyes carefully analysing the experimental log and using his free hand to swirl the vial, squinting at the deep, violet colour.
"Using fresh vallberries is undoubtedly an interesting choice. Its potency seems to have doubled," Dottore's hand leaves your waist as his enthralment with your creation takes over.
"I can't help but think this will be far too much for your body to handle, y/n. I'm sure Pantalone would be interested in this, though," he ponders.
"I didn't make it for Pantalone or myself," you say, summoning as much confidence as humanly possible.
A thick silence shrouds the air as Dottore turns to meet your gaze, clearly a little confused.
"It's for you," you blush, breaking the silence.
"oh... oh-"
"Experiments need different variables, after all," you stumble, trying to suppress the rising heat between your bodies.
"I suppose I could participate in your experiment... for the sake of science, of course,"
You sigh wantonly. The glint of lust within Dottore's eyes was saying he wasn't merely participating for the sake of science. However, you'd stay quiet for the sake of his pride.
Dottore brings the vial of violet liquid to his lips, salivating the scent for a few moments before consuming it with a single gulp. Raking a hand through his hair, you immediately observed the pace of his breathing increasing by a tenfold. His fingertips grasp at the paper, reaching to write results.
"Forget the results, Zandik. Just tell me what you feel," you blurt out, pushing his body back from the bench and onto the nearby couch.
"Just- ugh, the usual, rising temperature," you closely watch Dottore's reactions, his breathing becoming rapid and face flushed with a deep red.
He looks so cute like this, you think to yourself.
Dottore's glazed eyes peer over, and you can tell he's attempting to hold himself back, still adamant about maintaining control.
You can change that... Slowly you peel off your lab coat, throwing it across the floor. You proceed to strip the rest of your outerwear as slowly as possible, adding the items to the pile across the floor. Eventually, you were left in nothing but a matching set of white, lacey lingerie that you had carefully picked out with the help of Damslette. Attempting to maintain your confidence, your eyes make contact with Dottore's. His pupils blown wide open, face covered with a sheer layer of sweat. Sure enough, a prominent bulge had formed within his pants.
"Wasn't this meant to be an experiment?" Dottore musters with shaken breaths.
"Why are you torturing me instead," he continues, his voice now a low growl.
Stepping forward, you place your hands gingerly on Dottore's cheeks, feeling his body's searing heat burn into your palms.
"You can have me however you like, but you have to be patient," you whisper against his skin, pressing a slow kiss against his lips.
Dottore almost whimpers as you pull away from the short-lived kiss, his body aching with desire as he becomes more desperate for your touch. Dottore wanted nothing more than to hoist you up onto the lab bench and fuck you right there, but what a shame it would be to ruin the pretty lingerie that clung to your curves, the thin fabric just barely concealing your hardened nipples and leaking heat.
"Hurry up then," Dottore huffs, embarrassed by the state of his desperation.
"Hurry up, and what?" you ask, pleased Dottore wasn't opposing your wishes.
"Hurry up and... touch me,"
Part of you doesn't want to deprive Dottore any longer, his eyes longingly scanning your exposed body, desperate for your touch. So you make quick work undressing his searing body, taking your sweet time pressing kisses across his neck and chest, intently listening to the faint moans escaping Dottore's mouth. A finger loops through the centre of his harness, pulling it back slightly before releasing the tensed leather, snapping against his skin.
"Ahh-" Dottore emits a breathless moan, his hands reaching out to take hold of your bare waist with a bruising grip.
"Did I make the aphrodisiac too strong?" you ask aloud, tracing your fingertips over Dottore's clothed, throbbing length.
Dottore squeezes your waist harshly, forcing a gasp of surprise out of your lungs. Your chest tightens as you straddle Dottore's lap, freeing his cock from the constraints of his undergarments. Precum covered the tip of his length, a wet spot smudged across his undergarments you had now thrown across the room. Dottore leans into your neck with a groan, pressing his lips against the column of your throat, teeth grazing the sensitive skin and forming a blooming red mark.
"Please, don't stop," he pleads against your ear.
You hum in response, fingertips spreading the beading precum across his length before shifting your panties to the side. The white lacy garment is already soaked with your arousal, messily spread across your thighs. Then, raising your hips, you line up Dottore's rock-hard cock against your fluttering hole, sinking down slowly. A wanton moan escapes your mouth as you realise how much thicker the aphrodisiac had caused Dottore's cock to swell, your hands gripping onto his shoulders.
"Ah- it's too much," you cry out in shock.
"You can take it," Dottore retorts with a hopeless groan, pressing his thumb to your clit and rubbing slow circles over it.
The pleasure radiates through your body, the sheer amount of slick produced by both your bodies allowing Dottore's length to become sheathed entirely within you. Your arms encircle Dottore's neck pulling him close and burying your face into his shoulder, your tight walls clenching as his cock twitches within you, frantic for more friction.
"Ngh- y/n," Dottore moans against you, his hips stuttering as he realises you weren't making any effort to move.
"Let's just stay like this for a moment. You can do that, right?" you stammer, still adjusting to the feeling of Dottore's cock buried within your plush walls.
"Let me take this off then," Dottore's hand slips up to your lacy white bra, snapping apart the fastening and dropping it off your shoulders.
Dottore's gaze is unwavering as he pulls you off his shoulder, drawing you in for a sloppy kiss. You reciprocate the kiss gladly, inviting his tongue inside and deepening the kiss. Dottore's teeth graze against your bottom lip, his hips unintentionally thrusting up, sending a shock wave of pleasure through your body. Your back arches in response to the jolt of pleasure, your body heaving with sensitivity, just the same Dottore was on the verge of cumming just from the mere warmth and tightness of your spongey walls.
"y/n, let me fuck you," Dottore finally gives in, his fingers rubbing circles over your hardened nipples, causing you to whimper breathlessly.
"Let me fuck you before I lose my mind," he continues with a babble.
"Is that what you want?" you ask coyly, bringing a hand to his cheek and cupping it lovingly.
"There's nothing I want more," he responds, wincing as your walls clench in response to his sinful claims.
You nod weakly, surrendering your body to Dottore's desires. The air is knocked out of your lungs as Dottore's arms hook underneath your legs and pick you up. All whilst his cock was still buried deep inside your sensitive cunt. He takes a few steps forward before placing you on the laboratory bench, your heart flutters at the idea of sinfully covering the lavish furniture with your release. Without warning, Dottore finally pulls out of your sobbing heat, smashing his lips against yours to muffle your cries, the kiss lustful and frenzied as Dottore begins to lose control of his urges.
"Turn around," he instructs, offering an arm for support.
Unsteadily, you slide your body off the bench turning around. You feel more exposed than ever this way, breasts pressed against the cool countertop, your leaking hole at Dottore's disposal; however, at the same time, it was exhilarating. The mere sensation of Dottore's fingertips gripping the plush of your ass was enough for you to rut yourself against his throbbing length. Dottore's fingertips caress your sobbing folds, stretching them open just enough to align the tip of his cock with your sobbing heat.
"Are you ready?" he asks lowly.
"I'm all yours," you muster with anticipation.
Dottore thrusts harshly, burying himself to the hilt within your heat, your stomach coils with pressure as his hips snap ruthlessly, the drag of his cock against your tight walls drawing out a string of feverish moans from your lips. Dottore's arm wraps around your waist, pulling you up from the bench, flush to his chest, taking the opportunity to roll a sensitive nipple between his fingertips.
"Ah ahh- Zandik," you mewl out, feeling tears form at the corners of your eyes.
"Slow dow- down," you stammer, struggling to keep up with his relentless pace.
"I'm sorry y/n, but I'm going to fuck you so hard, you'll never want to experiment with aphrodisiacs ever again," Dottore growls in response.
Dottore fans his hand out against your lower stomach, pressing down lightly, his cock hitting deeply against your most sensitive spot simultaneously. The double-up of pressure elicited a sharp shriek from your raspy throat, the coil of pressure at the pit of your stomach tensing rapidly.
"I'm so close," you manage to splutter, hands gripping the edge of the bench for dear life.
Rather than continuing his ruthless pace, Dottore forces himself to withdraw from your body, moaning out as your tense walls spasm from the friction. Tears stream down your face, your body disagreeing with the denial of your ever-so-close orgasm. If it weren't for Dottore's wrapped arm around your body, you would have instantly collapsed to the floor. Without giving you a moment to voice your frustration with Dottore's choice, his arms turn you back around to face him, hands gripping your waist and hoisting you back up, perched at the edge of the bench. Dottore's chest heaves, cock throbbing against his stomach with an angry red colour, on the verge of release.
"You're always so good for me," he rasps, peering at the fluids streaming down your thighs and onto the cool surface.
"Just a little more. I'll finish what you started," he whispers into your ear, distracting you by sinking his teeth into the crook of your neck, sucking roughly whilst thrusting back into your abused hole.
You wrap your arms around Dottore's neck tightly, holding on for dear life as the pain from your denied orgasm quickly warps back into pleasure. The sound of wet skin slapping and the uncontrollable moans of the both of you fill the room.
"Feels so good, so good," you whimper, lips pressing kisses along the column of Dottore's throat.
"Ah- y/n, I'm close, gonna cum," Dottore brokenly gasps.
"Where do you-"
"Wherever you want," you answer, instantly desperate to reach your climax.
"I'm yours, Zandik," you whisper against his ear.
Those simple words unleash your climaxes, Dottore thrusting a few more times before emptying himself within you. Your back arches as the high ripples through your body, holding Dottore close as you feel ribbons of thick hot cum fill your insides, coating your overstimulated walls. Dottore slowly pulls out after a few moments, chest heaving with exhaustion, saliva messily dripping from the corners of his swollen lips. You shift slightly, feeling the mixture of Dottore's cum and your release spill out sinfully across your shaking thighs and onto the bench. If you weren't utterly exhausted, you would have been quick to jump off the bench and clean up the evidence of your lustful endeavours, yet instead, you collapsed against Dottore's chest, attempting to gather your strength.
"Let's get you cleaned up," Dottore softly says as your heaving breaths begin to stabilise.
You lose track of time in your post-climactic haze, and before you know it, you are settled in a bathtub submerged in warm water. You sigh as the warmth soothes your aching body, Dottore's chest pressed flush against your back, his hands rubbing soap gently across your bruised shoulders.
"Hm, when did you become so doting," you hum, propping your body up as your strength returns.
"I got carried away," Dottore says quietly.
"Sorry if I hurt you," he continues pressing a kiss against your neck.
"Hurt me? You did everything but hurt me," you respond with a giggle.
"Come sit in front of me. I want to wash you up too," you continue shifting your body forward to give Dottore space to move.
Dottore hesitantly moves to sit in front of you, pleased with his compliance, you lather his body in the body wash nearby the bathtub. The faint scent of Sumeru Roses filled the room as your hands worked over his slender shoulder blades and back. You continued to work the nearby shampoo into his dishevelled cerulean-coloured hair, fingertips gently massaging his scalp and ensuring you had thoroughly cleaned his hair.
"You're awfully quiet," you say as you rinse out the shampoo.
"Ah, don't mind me. I'm merely enjoying the attention," Dottore responds stoically.
You dry yourselves off in comfortable silence, Dottore offering to carry you back to bed as your legs are still unstable. The bed, as always, was slightly cramped due to its small size, forcing you to bury your face into Dottore's chest... not that he minded. His arms wrapped around your waist and held you close, doing his best to keep you warm in his unusually cold private office.
"y/n, doesn't living in the laboratory get uncomfortable?" Dottore asks before you can fall into a slumber.
"Not really, I suppose I'm used to it," you respond.
Your mind flashes back to when Lord Harbinger Pantalone believed you were a prisoner of Dottore's. He initially offered to break you out for the small cost of one million mora. You had to hold back an explosion of laughter as you explained you were merely an assistant that didn't have much use for leaving the laboratory. After all, any required materials for experiments or living conditions can be provided at the click of a finger when you have the status of the Second Harbinger of the Fatui.
"Why do you ask?"
"I own an estate just a few blocks from here. Perhaps you would be more comfortable in a legitimate residence," he responds whilst propping himself up on a forearm.
"Eh, a legitimate residence? That would be far too lonely, though," you sigh, bringing your hand up to brush over the scar that ran down his left eye.
"Naturally, I'd- I'd live at the residence alongside you," Dottore stumbles on his words, flustered by your gentle touch.
You found it amusing that time and time again, even after completely fucking you out of your mind, Dottore would still be shy of your touch. Perhaps he wasn't used to such a level of affection after spending years completely enthralled by experiments and Harbinger duties to distract himself from his nation's rejection.
"You want to live together?" you finally piece Dottore's request together, a smile tugging at your lips.
"Don't make me repeat myself," Dottore mumbles, burying his face into the crook of your neck to hide his bashful face.
"The answer is yes," you respond teasingly, ruffling his blue locks with your free hand.
Dottore raises his head to plant a kiss hastily on your lips before readjusting his arms to encircle your body warmly. You lay your head against his chest, feeling your lethargy take over as the sound of Dottore's steady heartbeat allows you to fall into a deep slumber.
-BONUS-
"Did you get rid of your assistant?"
"What on earth are you talking about?"
"That pretty assistant of yours wasn't at the lab when I came to collect the favour we agreed upon. It was beyond strange,".
"Watch your mouth, Pantalone," Dottore scowls, Pantalone seated across from him as he shifts a chess piece across the board.
"You didn't kill her off, perhaps? An experiment gone wrong, perhaps?" Pantalone continues to jest, awaiting Dottore's next move.
"I did not kill off y/n, you moron," Dottore snaps, taking his turn to move a chess piece.
"She has simply relocated somewhere more suitable for her likes," Dottore continues with a pleased hum.
Pantalone's inquisitive gaze refocused on Dottore's abnormally calm demeanour. Slowly piecing together the puzzle presented before himself before chuckling at the realisation Dottore's humble assistant had captured his seemingly cold heart.
"Hm, I believe the Tsaritsa would be pleased to hear you have embraced the humble emotion of love," Pantalone remarks moving another chess piece.
"Embraced? I wouldn't say embraced is the right term. Beguiled is more fitting," Dottore retorts, making a final move across the chess board.
"Checkmate,"
Dottore hums with the satisfaction of his victory, collecting the pile of mora settled at the edge of the tabletop.
Beguiled. Otherwise known to mean captivated, enthralled, seduced or infatuated. Indeed, Dottore is nothing but completely in love with you. However, Pantalone can burn in hell if he wants to hear him say that outwardly...
