Work Text:
Small bubbles float to the top as Chan taps the syringe. He squeezes out some of the liquid and places it back onto a small metal tray alongside seven others. One final time, he counts them, twists them, and makes sure everything looks alright.
“Is everything ready?” Chan asks, eyes seeking his assistant.
The sight of a short, stubby man with thick glasses and a prominent five o’clock shadow smiles back at Chan, nodding. His square neck bulges, the scabs he keeps picking at glints under the fluorescent lights, and Chan wonders when he’ll have the time to address the obvious hygiene issue. Today’s not that day, though. No, the experiment they have planned is far too important to mess up with any type of quarrel.
“I think so,” his assistant croaks out, voice hoarse from at least forty years of smoking cigarettes. “We’ve kept an eye on their food intake for two weeks now. I checked their weight and their blood pressure earlier this morning. Their IV drips are connected alongside all the tubes, and I have yet to hear any complaints.”
“They’re good at that,” Chan hums, smiling from ear to ear. “Not complaining, that is.”
He pulls the tray with him as he walks forward. The plastic wheels shriek, but no one in the room reacts. When he reaches the center of the room, he holds out his hand and waits for his usual greeting.
Felix looks up at him with round, brown eyes. He cranes his neck and places his chin in Chan’s hand.
“Good boy,” Chan murmurs, rubbing his thumb over the young man’s lower lip. He’s not meant to have favorites. Mainly because it might affect his view of Felix’s performance - ultimately increasing the risk of bias when he writes his research articles. However, there’s an undeniable tug around his heart as he watches Felix nuzzle into his touch, lips turning upward.
None of his other experiments are as eager as Felix is. Some are… at times. But most of them remain rather neutral. Too fearful to do anything to anger him.
“Are you ready?” he says to everyone, but truly, he only wants to see the fluttering of Felix’s lashes alongside his deep timber whisper affirmingly. Quite regrettably, Chan lets go of Felix’s face, stepping backward before taking a sharp stance in the middle of the room.
In the far corner, Chan watches as his assistant scurries over the floor, hands wildly grabbing his gloves and apron. Although the frantic movements are amusing, and Chan could spend days laughing at the man. It isn’t what he truly cares about.
What he cares about is right in front of him.
On all fours, with their head raised and eyes curiously looking at Chan, are seven men. He’s arranged them by age. Like he always does. Their knees are propped up by soft pillows, and their wrists are supported by an extra cushion. Though, Chan won’t mind it if they need to lower themselves onto their elbows. However, he’d appreciate it if they stayed like this for a bit longer.
After all, they look magnificent this way.
At the very left, there’s Minho - his oldest. They’re all relatively close to each other in age, but to be honest, Chan quite likes it when they are even closer to his own age. The power he holds above them feels sweeter that way. When their glossy eyes look up and they whisper “hyung” his heart nearly beats out of his chest.
Some say he shouldn’t get too attached to his experiments. That may be true. But then again, these men aren’t really supposed to be going anywhere in the near future, so he might as well hold some fondness for them.
He met Minho at a bar down his street. His straight brown hair and sharp nose adorned by feline eyes had made Chan’s knees grow weak. However, Minho hadn’t been an easy catch. Chan spent a whole month trying to get his attention, and only when he made a fool out of himself by fumbling another man did Minho batter his eyelashes.
Back then, Minho thought Chan to be aloof and rather clumsy. However, after a few drinks and some well-placed pick-up lines, Chan had managed to slip inside Minho’s chest, burrowing himself in a little cave near his heart.
Their first time together had been the perfect act of push and pull. Minho acted like he didn’t want Chan’s advances. Once, he even slapped his hand away, a scowl on his face. But Chan had quickly understood that such reactions were just Minho’s way of teasing him. After all, he’d fucked Minho from behind in the bathroom stall at the bar. He still remembers the feeling of when he first slipped his cock between those thick thighs - none of the others rivaled him in that aspect.
It was a pity Minho had spent his first two weeks in Chan’s laboratory entirely mute. He missed their banter.
After Minho came Changbin. Changbin is entirely different from Minho. Although his broad physique would deter most men from talking to him, Chan had found himself spellbound by the slightly shorter man.
They met at the gym, also close to his house. Chan lived very centrally. All the amenities served him well. Though, his laboratory is located a bit outside of the city. Changbin worked out nearly seven days a week, a feat which is greatly visible on his body - even some of the other experiments have taken a liking to the man’s biceps.
Chan had spent days trying to figure out how to approach him. He’d thought of ways to maybe ask Changbin for diet advice, or maybe some exercises. He’d even considered asking him about where he got his compression shirt. However, all of that was useless, for it was Changbin who approached him first.
He still remembers that sweet caramel voice, slightly deep and all too caring. “I just wish to help,” Changbin said when he saw that Chan’s bicep curl wasn’t executed correctly. Oh, his heartbeat had reached such speeds it was nearly out of control. He still remembers Changbin’s hands correcting his posture and the smile that followed when he complimented Chan’s physique.
When Changbin confided in him his preferences for bottoming, Chan knew this was it. Changbin had to be his. He was an excellent lay. Pliant, willing, and utterly needy. Sometimes, he even wonders if Changbin’s neediness rivals Felix’s. Not that he wants to compare everyone to Felix. They are all here because Chan loves them.
So dearly.
Compared to Changbin, Hyunjin is far longer. Although his body also brims with muscle, his upper back especially filled out, the man appears heads taller than everyone else. Admittedly, it was one of the reasons why Chan couldn’t stop staring at him when he first saw Hyunjin at the art shop.
Chan doesn’t even fucking like art. He can draw a few stylized figures, and back when he was thirteen, he dabbled in some graffiti, but that was about it. However, he has friends who enjoy art, and if Chan is anything, he’s a good friend. So, he’d walked into an art shop, entirely blind as to what he wanted or needed. Even when he asked for help, he didn’t grow any wiser.
Probably because he couldn’t hear a single thing that came out of Hyunjin’s mouth, for all he could imagine was how his hands would look around Hyunjin’s pretty neck.
Hyunjin has an aura that none of the other experiments have. His passion and love for the world is unmatched. He sees something beautiful in everything, even the smallest object. Hell, Chan’s sure that if he held up a single grain of sand, Hyunjin would be able to procure a sentence so vivid and enthralling that it would seer itself into Chan’s heart forever.
Back then, Hyunjin had found him endearing, cute even. Chan didn’t mind it, and when he learned that Hyunjin didn’t even particularly like it when men acted cute - he just liked it when Chan did it - well, Chan decided to never stop.
Chan didn’t really date, not in the traditional way, at least. However, Hyunjin was one of the few who managed to drag him out of the house to go sit at the top of a hill, simply enjoying each other’s company. Those times are still fresh in Chan’s memory, and he can still feel Hyunjin’s shivering body when he fucked him into overstimulation, those long fingers of his leaving streaks of red.
Quite like Minho, Hyunjin had also spent his first few weeks in the laboratory mute. Though, he did reach for his brushes here and there.
A quiet sob spills free from Jisung’s lips, and Chan rushes over, the syringes on the metal tray clanking together. “Hey, hey,” he hushes, hand cupping Jisung’s chubby cheek. “Why are you crying?”
Jisung stares up at him, his arms shaking from being on all fours for so long. It’s so cute. Jisung is adorable no matter what he does. Chan hums a quiet little song, the one Jisung sang back when they first met.
From time to time, Chan dabbled in music. Some people had spoken highly of his skills. Said he was a prodigy, and had true potential to break out in the music scene. He was rather good. Music came easily to him. A bit like sleep and eating comes easily to others. But alas, he didn’t pursue such a career - the medicinal field had called to him instead.
However, Jisung was not foreign to dabbling in the art of music. Chan was a fan of his work - had been for a long time.
They met at a jazz bar close to the hospital Chan used to work at. It was a quaint little spot, one where the crowd couldn’t surpass fifty for then it would be far too many limbs in one spot. Thus, he often had to fight for tickets to the show. It was tough and it cost him far more money than he expected. However, Chan wasn’t a quitter. He had to get tickets. How else would he be able to see Han Jisung on stage?
When they first met, Jisung had long, black hair with a loose perm. It gave him the look of a rockstar rather than a jazz musician. In hindsight, this might have been one of the things that attracted Chan so much to Jisung - he was unafraid of being who he was, and he never compromised his style for anything or anyone.
Like with most things in Chan’s life, he quickly found a favorite seat in the jazz bar. It gave him the perfect view of Jisung as he sang them through the night. That spot was also a prime spot for Jisung to notice Chan and his frequent smiles. The two of them spent at least four sessions of pure eye-fucking before Jisung approached him and whispered in Chan’s ear, asking if he was this dedicated to him behind closed doors as well.
“These are tears of excitement, aren’t they, Jisung?” Chan muses, his eyes kind and warm as he digs his thumb into the man’s cheek.
Jisung never answers. He knows not to. It’s one of those things that Chan appreciates with him. - his willingness to comply is only beaten by Felix. Chan tilts his head and looks over at the next man in line.
Felix’s skin is full of sun-kissed freckles; they run from the tops of his shoulders and down his back, where some are even spattered over his round ass. Chan sucks in a breath and takes in the sight of his slightly arched back. Now, that’s how it should be done.
On paper, Felix was the last one to join his experiment. However, that was only because Chan had somehow managed to lure the naive young man into his house - far too willing to do everything Chan asked of him.
When he was young, Chan had always been fascinated by the idea of trapping animals. He’d drawn little bunnies in cages, foxes in deep holes, and even pigs trapped in a small barn. Of course, he knew of those who enjoyed seeing animals suffer, but he wasn’t like that. No, Chan much preferred to imagine how they would adapt to their new surroundings. Would they squeal, panic, or try to escape?
He was interested in their behaviors. And so when he first experimented on their house cat Felix - what a perfect name for a cat - Chan had found that although the animal had grown depressed and unwilling to eat, he could still reach in and pet it and it would respond with love.
Unfortunately, that experiment didn’t last for too long. His parents weren’t too fond of such things, and Chan was forced to let the cat go. It did please him that the cat seemed to always want to sit in his lap after that whole endeavor, almost as if it had latched onto him like never before - in a twisted way that only made Chan’s heart flutter with excitement.
Felix, not the cat, had come into his life nearly ten years ago. He was new to Korea, and the language barrier sent him into a depressive spiral. Chan was there to pick him up and nurture him back into a far more positive world.
Although they never became an item, most people saw them as one. Chan introduced Felix to all of his friends, his hand often resting on his lower back. He loved seeing Felix flourish in Korea. He loved to see him smile and laugh whenever they would go and watch a new superhero movie together. But he loved it even more when Felix’s eyes would dim into a gray when Chan slowly ruined every friendship he had.
When Felix was sad, Chan was his safe person.
Felix would come knocking on his door whenever he was down and Chan would always let him in with a warm hug. One day, Felix never left, and Chan was awarded his perfect little plaything.
Unlike the others, Felix hadn’t made a fuss when Chan brought him to the laboratory without any explanation. He’d only smiled and nodded, fingers reaching for Chan’s hand when he thought no one else was watching.
Of course, Chan could never openly show his love back; that would be unfair to the rest of them. But there was a reason why Felix’s syringe was just a bit fuller than the rest.
Whereas Felix walked straight into his cage, Seungmin did not - but, in a way, Chan loved that just as much.
Seungmin is an enigma. Honestly, Chan’s not quite sure if he has him figured out. The two first greeted each other when they applied for a job at the hospital. It wasn’t the same position, so Chan had been elated to learn that Seungmin had also gotten the job.
Precision and keeping one’s head cool is important for anyone working in a hospital. However, no matter how dutiful and tedious Chan is, he can never compare to Seungmin. The man’s keen eye for the smallest details will never stop amusing him.
They would share resources and ideas for how they could optimize their work together during lunch. He looks back at those times with such fondness that his heart brims with happiness. However, that’s not why Seungmin’s an enigma. No, that whole ordeal came when Seungmin one day pushed Chan into one of the empty patient rooms and twisted his hand in Chan’s scrubs.
“I don’t think I can handle it if you tell me no, Chan,” Seungmin had said back then. It was his way of asking him out on a date. It had been an entirely baffling scene. One that came out of nowhere. Yet, Chan’s cock twitched, and Seungmin didn’t need to be asked twice before he got into the hospital bed with his scrubs on the floor - ass presented for Chan’s taking.
Then there was Jeongin. Oh, how Chan had misunderstood that man. At first, he’d been certain that Jeongin was timid and uneasy around new people. However, after Chan started to attend the same singing class as him - a hobby he picked up because he wanted to impress Jisung - Jeongin became more and more talkative.
Sure, in the beginning, his fox-like eyes had been narrow and his sentences short with the bare minimum of honorifics. However, after a few sweet words and well-formulated praise for Jeongin’s singing skills, the man started to loosen up.
Chan mainly got to know Jeongin after their singing lessons. Somehow, the younger decided that he enjoyed waiting for Chan to be done so they could go to the nearest pub together and get shitfaced.
Despite a few years between them, they quickly found common ground on several things. Particularly fashion. Jeongin, although a student, spent a ridiculous amount of money on clothing, and he had no one to take pictures of his outfits.
Chan, someone who dabbled in a few brands of himself and who had taken a photography class to impress Felix, easily agreed to take Jeongin’s pictures. When the two didn’t sing or drink together, they would meet up in remote locations to take pictures for their respective Instagram accounts - although Chan has now deleted both of those accounts.
The location also proved to be a great spot to pry Jeongin into a position where Chan could undress him. He wasn’t one who enjoyed being touched, but Chan was never deterred by such things. A warm smile and careful words always got him what he wanted - even Jeongin’s virginity.
All seven men, Minho, Changbin, Hyunjin, Jisung, Felix, Seungmin, and Jeongin, are the loves of his life. All pretty, funny, and adorable in their own way. All entirely too trusting of Chan’s sweet touches and promises of a good future.
He doesn’t like to use brute force. That isn’t his style. Luckily, most of them didn’t put up too much of a fight - at least, not after three days in solitary confinement or after having food and water taken away from them.
Chan loves them all.
More than life itself.
And now they are part of his grandest experiment yet.
What a wondrous time to be alive!
The hospital never enjoyed his advances when it came to research on medication. Hell, they didn’t even enjoy it when he brought up conversations of various medical trials he’d read about. He hadn’t really read about them. No, they were all part of the various notes he had at home, in that one room where Felix wasn’t even allowed.
While he did enjoy seeing the behaviors of animals change when they were captured but still allowed to receive love, Chan was far more preoccupied with the thought of how a human responds to ingesting aphrodisiacs while in captivity. He has a million hypotheses, but most of them can be stripped down into a single question.
How far can he go before he breaks them?
Chan has spent the last two months coming up with an entirely new aphrodisiac. His assistant believes it's too early to test it out on humans, but such worries are not prevalent in Chan’s mind, for he knows how skillful he is. Seungmin knows it, too, and he doesn’t seem worried at all. In fact, Seungmin’s eyes appear glossy and eager where he is, on all fours, stripped naked.
He won’t harm them. This aphrodisiac shouldn’t have any long-lasting effects, and if it does, then Chan will make sure his assistant notes it all down. Maybe he’ll increase his salary a bit if it goes wrong. It’s always good to keep one’s workers happy with monetary gifts.
“Assistant, you may take these four syringes, and I will take these,” Chan hums. Pointing to the ones meant for Minho, Changbin, Hyunjin, and Jisung. The stubby assistant nearly squeals, a horrendous display of excitement that Chan can only scoff at.
“But sir,” the assistant says, stumbling forward. “This syringe is fuller than the-”
“Just a mere trick of the light, assistant. Now, let’s get this show on the road. They look so excited, don’t they?”
Chan smiles as he picks up the four syringes, all of them dangling in his hand. Taking his time, he looks over the seven men. Most of them are shaking by now, their limbs weary after being in the same position for too long. He’s proud of them. He really is. They’re all on their best behavior.
Well, if Jisung would stop crying, then it would be perfect.
A sneer crawls up his lip as he locks eyes with Jisung. The man instinctively lowers his head when Chan’s eyes narrow - a smart move, for he’s not in the mood for any defiance now. He’s tempted to watch his assistant give the first four their dosage. However, he can’t do such a thing, for they have allocated a minute between each syringe. Details are important for research, and Chan’s main focus here is research.
Thus, he gestures to his assistant, and the two of them wall up at the same time.
“Today is a great day, my loves. In this very room, you will all be witness to my creation. Isn’t that amazing?”
Chan taps his feet triumphantly, smiling so wide it nearly hurts when he hears a choir of, “We are honored, Sir.”
He’s so proud. Even if the experiment isn’t a success, Chan is sure he’ll be eternally struck with pride. The group of men he has in front of him are already far better than his previous one. Well, most things are better than the death of five young men.
Chan walks up to Jisung first. His hand lands on his lower back, palm flat. “You see how good Felix is?” he murmurs, pushing Jisung’s back down. “You can’t let his arch be better than yours, now can you?”
“N-no…”
“Not quite, Jisung. Say that again.”
“No, Sir.”
“There we go, baby. Inhale and exhale for me. You might start to feel a bit warm when the fluid enters your system.”
Jisung’s frightened shiver sends a jolt of excitement down Chan’s crotch, and he can’t help but let out a little moan, earning him an excited squeal from Felix, who wiggles his ass. Such a pretty thing.
So dumb.
One by one, Chan and his assistant administer the syringe. It should only take a few minutes to take effect. More than enough time for Chan to whisper sweet words into their ears.
“Please, Chan-”
“Oh, you’re begging already, Minho?” Chan’s chest warms, and he walks up to his first lover. He crouches down and places a chaste kiss on the man's swollen lips. “I haven’t heard you talk in a little while. I like it.”
Before Minho can say anything else, Chan walks behind him and digs his hands into Minho’s thick thighs. They’re as soft as they were when they met, even if Minho has lost some weight after arriving at the laboratory. He shouldn’t lose more weight, but for now, it’s fine. Chan’s far too preoccupied by the sight of Minho’s visibly loosening hole.
“So pretty,” Chan murmurs and Minho bites back a broken sound - one which goes straight to Chan’s already erect cock. He’s been hard for a while now, courtesy of his self-produced stimulant, but now that he’s finally about to test out his experiment, his cock is furiously red.
He dips a finger into Minho’s hole. It slips in so easily that Chan shudders. “Almost like a proper cunt, baby. Oh, you should see yourself. You are so pretty like this.” Minho’s thighs quiver with excitement as Chan aligns his cock to his hole and slowly starts to push in.
“A bit of resistance,” Chan notes, grunting. “But I can still easily enter.” Next to him, his assistant notes down his observations eagerly, tongue lapping out to lick over his lips - his hard cock barely making his pants strain. It’s a good thing none of his lovers need to fuck his assistant.
The deeper Chan goes, the more Minho’s whimpers turn liquid. He only has to fuck twice into his ass before Minho falters forward, his arms giving out. “Good boy, presenting yourself so nicely,” Chan moans, lovingly caressing Minho’s back.
“Still some resistance,” Chan notes, pulling out entirely to look at Minho’s gape. “Not quite there. Perhaps he needs a different dosage.”
“Should we move on to the next one, then? I think Changbin might be of the same-”
“There are far too many words coming from that ugly mouth of yours. Let me do my job,” Chan says, shoving his assistant back a few steps before he smears his precum over Minho’s hole and pushes in again. “Fuck,” he swears, digging his fingers between Minho’s thighs and massaging the soft, inner flesh.
It doesn’t take long before the aphrodisiac crawls up Minho’s spine and takes over his brain. Minho lets out such guttural moans Chan can’t quite believe the vocal prowess the man has. He searches for more of those sounds and continues massaging his inner thighs as he fucks deeper and deeper.
Unfortunately, they don’t reach orgasm at the same time. Minho comes first. Strings of white land on the bench he’s propped up on. Chan wants to laugh at the measly amount of cum Minho produces compared to him, but he foregoes such a thing because, at that moment, Minho’s wrecked body is far too cute to laugh at.
He pulls out with a loud squelch, still somewhat disappointed with the gape he leaves behind. However, he is time-restricted, and the next hole awaits him.
Chan takes a few steps to the side, cock still red and throbbing. His eyes go wide when he looks down at Changbin’s body. His broad frame glistens under the fluorescent lights. Sweat has started to seep through his skin - a sight so reminiscent of their time at the gym together that Chan nearly gets teary-eyed.
“Such a pretty little thing,” Chan murmurs. “My little pillow princess has missed me, hasn’t he?”
The view of Changbin’s round behind should be eternalized by a painter and hung up in museums. Chan drags his nails over the globes of his ass and marvels at the strong muscles that hide underneath. Technically, Chan isn’t one who seeks out muscles, often preferring his partner to be somewhat smaller than he is. However, he can’t deny Changbin’s appeal.
That appeal only grows better when he slips in a finger and Changbin moans. “Such a needy baby,” Chan hums, bending his digit repeatedly until Changbin lets out a series of whines. He’s missed this. He’s missed hearing those pretty sounds. In a way, it’s a pity that he has them all on all fours. Seeing Changbin’s face as he fills him up was always his favorite.
Alas, Chan must do what he needs to do.
He lines up his cock and starts sliding it in. “Ah, indeed, you were right. He is a bit tight.” Chan’s assistant remains quiet, but his pen scribbles down everything Chan says, even when he points out that Changbin’s sweat seems to be worse on the left side than the right side.
Despite this, Chan is practically drunk on pleasure. While Changbin isn’t as loose as he wanted him to be, the sounds he makes are out of this world. It’s so good, in fact, that Chan resorts to old habits and slams his hand into Changbin’s ass and watches it jiggle. Like always, such a slap sends Chanbin over the edge immediately.
“So embarrassing,” Chan laughs. “You came already!” He snaps his fingers twice and then gleams when everyone in the room laughs on cue, Changbin included.
They’re perfect.
With his length embedded deep into Changbin, Chan spreads his legs further apart and slams in harder. With feverish eyes, Chan watches Changbin’s muscles contract. It’s such a sight to behold that his own orgasm comes quicker than normal.
No one laughs this time.
“Now this looks promising,” Chan says out loud, waving his assistant to come closer. They both crouch down and tilt their head. “Hyunjin, your hole… It’s pulsating.”
With one finger sliding up and down Hyunjin’s ass, Chan and his assistant watches in awe as the rim opens and then contracts repeatedly.
“Definitely looser,” Chan says, and his assistant nods.
“Do you have a hypothesis as to why?”
Chan smiles and shakes his head. Then slams his palm into the assistant’s chest and forces him back again. “I do,” he huffs. “But I’ll keep it to myself for now.”
That guy always wants to talk and talk. Can’t he see that Chan is busy? That pea-sized brain of his probably barely registers Hyunjin’s need to be filled by Chan’s cock. That’s exactly why Chan’s the head of this experiment. He’s far more caring than his assistant will ever be.
“I don’t feel so good,” Hyunjin whimpers.
“I know, baby,” Chan coos. “I’ll make you feel a lot better.”
“N-no-”
A deep groan rumbles from his chest as Chan sinks his cock into Hyunjin’s hole. The man immediately clenches around him and sucks him in deeper. It’s magnificent, really. Even though the resistance is the same as that of Minho and Changbin, Hyunjin feels vastly different.
Chan bites down on his lower lip and reaches forward to grab a handful of Hyunjin’s long locks. Beautiful pleas for him to stop fill the air and it makes Chan’s thrusts grow harder and harder. He’s not as kind with Hyunjin as he was with the others, but it doesn’t really matter. What matters is that he tests out all the holes properly.
“Hmm, disappointing,” Chan sighs when he comes inside of Hyunjin and realizes that the other hasn’t quite reached his orgasm. “I think a higher dosage should be administered next time.”
“No, please!”
Chan reaches down between Hyunjin’s legs and wraps his hand around his hard erection. “Don’t worry, baby. I won’t leave you with blue balls.”
Hyunjin cries his way beautifully through his orgasm while Chan makes his assistant record the sounds for a later study.
Jisung is next. Earlier, his eyes were filled with tears. Now, those are gone. However, he still looks like a mess, for a steady drip of drool seeps down onto the bench he is on. His arch is deep, nearly perfect. At least Chan thinks it’s perfect as long as he ignores Felix’s arch in his peripheral vision.
“Sir,” Jisung garbles. “I’m dizzy.”
Chan furrows his eyebrows and reaches forward, his palm coming to rest on Jisung’s forehead. “You do feel a bit warm,” he says and shoots a worried glance back at his assistant. “Would you like some water, Sungie?” he asks, earning a slow nod.
There’s a groan from the rest of the group as Chan’s assistant stumbles forward with a full glass of water. The liquid spills over the rim, dripping down onto the floor. Seungmin’s mouth opens, and his tongue darts out. “Cute,” Chan muses and takes in Seungmin’s shivering form before returning his attention to Jisung.
He grabs the glass and brings it up to Jisung’s lips. At first, he doesn’t really respond, but when Chan pries his mouth open, he starts gulping down the water. “Not too quick, now,” Chan whispers, carding through Jisung’s hair. His erect cock rubs against Jisung’s side, making both of them groan.
“Place it on the floor,” Chan says to his assistant, removing the glass from a displeased Jisung. “In the middle so they all can see it.”
Chan walks behind Jisung and wastes no time. He is, after all, conducting research, and he needs to be mindful of any lost time. As he slips in two fingers, Jisung groans a long and languid sound. “Oh, there we go,” Chan smiles. “He might have reaped more benefits from the aphrodisiac because he is one of the smaller ones.”
The insides of Jisung’s body feel hot around his digits. The walls are slick and smooth, similar to the flesh on the inside of one’s cheeks. Chan has used Jisung’s mouth several times. Something about those puffy cheeks around his cock always drives him mad, and so when he starts pushing into Jisung’s ass, Chan can only imagine his mouth.
“Less resistance!” Chan says out loud, nearly cheering when he only needs two thrusts before he is entirely sheathed. He tries to look down at Jisung but quickly realizes it’s in vain. His eyes are glossed over, and the drool from before has nearly tripled. It isn’t really a pretty sound, so Chan reaches forward and shoves Jisung’s head down on the bench.
“Stay,” he orders and slams his hips into the drugged man.
Much to his surprise, Jisung comes nearly immediately. He does so with a series of whines and whimpers, his little cock sputtering white strings. It’s so cute that Chan can’t help but pinch his cheek, immediately wiping it on his assistant’s coat when he gets drool on it.
He’s starting to feel the effects of his own injection start to wane, and so after he fills Jisung up with his seed, Chan retreats to his desk and reaches for another syringe. His cock is still red and throbbing, but the sensation at the base has started to change.
The needle slips in with some effort, Chan groaning as he feels the process of everything hardening again. “Fuck,” he curses and throws the syringe onto the floor, stumbling towards the seven men all lined up perfectly for him.
Minho’s head dangles, Changbin’s hips rock back and forth, Hyunjin’s arms have given out, and now Jisung reaches behind and stuffs two fingers back into himself.
What a glorious sight.
“Wait, aren’t you supposed to go to-”
Chan clicks his tongue and waves dismissively at his assistant. “Do your job and take notes!” Body stiff and his cock raging with desire, Chan steps up behind Seungmin.
The thinner man shivers when Chan runs his hand down his back, teasing him by nearly slipping a finger inside. “So quiet,” he muses. “Cat got your tongue?” Seeking Seungmin’s hidden moans, Chan reaches down and wraps his hands around his balls, squeezing them until he hears Seungmin whimper.
“What a masochist,” he murmurs.
Chan keeps his hand on Seungmin’s balls as he uses the other one to test out his hole. He slides his index finger around the rim, smiling happily when it pulsates - similar to Hyunjin’s hole. When he dips it inside, Seungmin sobs, his hips instinctively rocking back and forcing Chan in deeper.
“Such a good pup.”
He heeds Seungmin’s wishes and removes his finger, replacing it with his cock. It’s just like he thought it would be. Two thrusts, and he can feel Seungmin’s ass cheeks against his crotch.
“Same resistance as with Jisung. My theory is that it is due to their similar weights.”
Next to him, his assistant scribbles furiously, his mouth agape as he sees Chan’s cock slide into Seungmin’s slender form. There’s not much muscle on the man, so his cock appears even larger. Perhaps it did grow a bit after the extra dosage, but it doesn’t make the view any less depraved.
“Look at that!” Chan says loudly, demanding everyone’s attention. He points down at Seungmin's body. He’s rocking back and forth. He’s fucking himself on Chan’s length. There’s not even a need for Chan to move, he can simply stand still and enjoy the show.
That’s exactly what he does. He widens his stance and groans, leisurely placing his hands at the back of his head. “Such a good pup.” His eyes remain on Seungmin’s body, swallowing up his erection. “Everyone else should learn from our dog.”
Similar to Jisung, Seungmin comes first. But his ass clenches down so hard on Chan’s cock that it forces out his own orgasm. However, Chan doesn’t even attempt to milk himself. Seungmin does it for him, riding himself through overstimulation simply to harvest every last bit of Chan’s come.
When he slips out, Seungmin cries for more, his head whipping around. Pleading eyes seek Chan’s, and for a split second, Chan nearly gives in and fucks him again. But when Jeongin whines and his brows furrow, that thought quickly disappears.
“Are you seeking me out for once, Jeongin?” Chan laughs. “I thought you didn’t like to beg for my attention?”
“Please,” Jeongin whimpers, his back arching, accentuating the surprising tone of his muscles. If Chan finds it in him, he might offer more rations to Jeongin - feeding his greedy wish for the young man to perhaps reach the size of Minho or Changbin.
“Please?”
“Please, hyung…”
“No,” Chan shakes his head. “I’m not your hyung.”
“Please, Sir.”
Chan furrows his brows again, bringing his top to the roof of his mouth. “No.”
“Please, oppa.”
Something stirrs in Chan’s chest and he reaches between Jeongin’s legs. He squeezes his soft thighs all the way up to Jeongin’s cock. “Hold it,” he orders, smiling when Jeongin flattens both his erection and his balls against his lower abdomen.
“Such a pretty girl,” Chan muses, looking down at Jeongin’s loose asshole. “A pity this cunt has been used so many times it’s all loose now.” From somewhere in the room, another one moans. Chan’s not entirely sure who, but the deep timber runs straight to his cock, and he taps his thumb over Jeongin’s boypussy.
Copying Seungmin, Jeongin moves his hips. However, instead of pushing Chan’s digit inside, he sways them from side to side, mimicking the act of having his clit rubbed. It’s a sight that sears into Chan’s mind, and he can’t help but imagine if he one day can replicate it properly.
“Oppa,” Jeongin whines. “Please.”
“So needy. Have you taken lessons from Changbin or Felix?”
This time, Changbin lets out a cried moan. It pleases Chan to the core. They are all so perfect. So pliant and so willing to be good for him. It nearly makes him forget about the times when they aren’t.
He doesn’t allow Jeongin to answer, at least not with words. Chan slips in two fingers and curls them. “Yeah, we definitely need to change the dosage for some of them.” While he scissors Jeongin open, he converses with his assistant quietly, ignoring the whiny pleas that fill the air.
Once his assistant steps back, Chan returns his attention to Jeongin and shoves his cock right inside. “Fuck what a loose cunt you have, Innie. How many people did you let fuck you?”
Jeongin garbles out a reply so incoherent Chan can only laugh. He isn’t really that loose. At least not compared to Jisung and Seungmin, but he still feels good. And he feels even better when he tries to spread his legs even more, demanding Chan’s cock to go deeper.
Lewd squelches fill the room as Chan slams his hips into Jeongin. He knows he likes it this way. He always did. Even back when he clawed at Chan’s neck and sobbed as his clothes were ripped off. Such memories are locked away in a special little chest in his heart, one he only opens when he wants to be extra rough.
“The others are probably jealous of you,” Chan groans. “They weren’t allowed to be fucked this hard.”
Jeongin whines and shakes his head, tears springing free. When Chan forces in another finger alongside his cock, Jeongin comes with a cry - having rubbed his palm against his length for so long while he kept it hidden from Chan’s gaze.
Chan cracks his neck and looks down at his length buried deep within Jeongin. “Make sure it takes, yeah?” Another round of cum spills out and soaks Jeongin’s insides, making them even softer and smoother than before. “Good girl.”
When he pulls out, Jeongin collapses. His head dangles off the bench as he heaves for air. Chan shrugs. He can deal with that later. He has something far more important to deal with.
He runs his fingertips over Seungmin’s back before moving over to Jisung and then finally to Felix.
“Now, what do we have here?”
It’s embarrassing, but Chan nearly comes the very second he looks down at Felix. His warm skin shines with sweat. Beautiful freckles adorn nearly every part of his body, resembling that of the stars above - the ones Felix hasn’t seen in several weeks.
That same beautiful arch from before is still there. However, Felix has now gone the extra mile to lure Chan in. Yes, even a captured animal can lure its captor in. Felix’s cheek is flush with the bench. His head turned to the side so that when he peers up at Chan, it is a struggle. His long, black eyelashes are wet with sweat, or tears, and his lips are slick with drool.
“Hi baby,” Chan smiles, earning him a whined moan from Felix, who shakes his ass and reaches his hand behind his body only to grab his ass and spread it apart.
“Now, this is perfection.”
Without turning around, Chan beckons his assistant forward. “Look at this. Can you see how pretty that gape is, and he hasn’t even been fucked yet?” Like the idiot he is, the assistant only garbles out a response, his hips fucking the air. It’s disgraceful and not at all what Felix deserves. Yet, Chan needs him to see everything so that their observations are properly written down.
“You’re so pretty, Felix. The prettiest one in here.”
Felix preens, a dizzyingly beautiful smile forming on his blushed face. “Chris.”
Chan groans and reaches forward, steadying himself by grabbing onto Felix’s hand. He looks back at his assistant with a scowl before he steps forward and sinks his cock inside - with absolutely no resistance at all.
It’s beyond anything he’s ever felt before. Felix’s insides pulsate, warm and wet. Although his hole is open and needy, the rim clenches instinctively around the base of Chan’s cock. A perfect response. None of the others even comes close. Chan’s heart swells, and he leans over Felix’s needy body and plants a chaste kiss on his back.
“You see?” Chan says with pride as he stands back up and slowly starts to fuck Felix. “I knew he’d respond to it differently. His body is not quite like theirs.”
“Sir, I fear I must remind you that Felix’s syringe had more of the solut-”
Chan shakes his head, nearly too intoxicated by Felix’s responsive body. “No, they were all filled exactly the same. I made sure of that myself.”
“But, sir…”
“Must you ruin this moment for me?” Chan growls, the grip on Felix’s hips tightening. “Write down that YB1 has shown excellent prowess and that he should be the ideal from now on.”
When Felix whimpers in pain, Chan eases his hold and apologizes profusely, softening his thrusts. He shouldn’t fuck Felix slowly for too long. No, that would only be cruel, for Felix is entirely lost to the pleasure - far more than any of the others were.
In fact, his body’s response is so extreme that Felix comes twice within the span of five minutes. Even the amount of cum landing on the bench is impressive, and Chan takes note of his apparent hyperspermia.
“Now,” Chan forces out. “What if we combine the aphrodisiac with the enhancer?”
“The one you administered to yourself?”
“Yes, of course, what else?”
Felix’s body shudders through another orgasm, and Chan coos, his heart full and his chest puffed out with pride. Embedded deep inside, his cock twitches happily, and Chan allows his own body to accept his imminent orgasm.
Filling up Felix only once would be entirely unfair, and so Chan remains in his spot. Somehow, the glide becomes even nicer, and Chan’s able to force three fingers in next to his cock.
“Alas, we shall not do that this time. I don’t wish to break my favorite toy.”
Felix smiles through the praise, a flush of rose creeping up his neck and cheek. He’s far too adorable for his own good. Such a sight only makes Chan want to fasten a collar around his neck so that he can parade Felix around on a leash.
Simply imagining that has Chan hunching over and digging his nails into Felix’s side, filling him up with even more cum.
It pains him, but after a second round, his cock starts to throb in an uncomfortable way. Chan watches with tears in his eyes as he pulls out of Felix, brows furrowing even more when the man shakes his head and begs for more.
A near-full literary novel fills the air when Felix pleads relentlessly. His cries are only softened by Jisung reaching out to wipe away his tears.
“My pretty boys,” Chan muses. He stumbles back, shaking his head in disbelief.
Seven men.
All of them filled with his seed.
Seven men.
All of them eternally grateful to be captured by him.
“I must say,” Chan smiles, “the experiment was a success. I am a success.”
“Well done, Sir.”
