The thought hits Mark like a freight train while he is dick-deep in Donghyuck.
Donghyuck is teary-eyed, knotting in Mark’s hands, an alpha hanging already on an omega cock– Mark’s cock, and somehow the animal in Mark still rears his head. He imagines it, depraved and demeaning, with shocking clarity and lets the image be printed at the back of his eyelids before he comes hard enough for his vision to white out.
Later, when he has bullied a less pliant and yet equally whiny post-sex version of Donghyuck into the tub, scrubbed off the caked cum on their abdomen, and settled into bed with his alpha’s arm around him, the first emotion he feels is guilt.
Guilt, because it is not like Donghyuck does not let Mark get away with it enough. Sure, Donghyuck matches Mark’s freak as if he was plucked right out of Mark’s nastiest fantasies. But at the end of the day, Mark gets to bully his cock into his alpha’s hole and watches with dark amusement as his alpha knots painfully in the air untouched. Gets to have Donghyuck open his lips at Mark’s sharp command and Mark’s spit hit behind his gums. Mark gets to place his greedy hands over Haechan’s neck, leave imprints of his teeth over Donghyuck's shoulders, and bruises in the shape of his fingers over Donghyuck’s thighs. And although Donghyuck enjoys it; the manhandling, the bullying, the humiliation, and the rush of pain-pleasure, it feels to Mark downright ungrateful to hunger for more.
However, as with everything related to Donghyuck, these thoughts bleed into his waking moments, eating away his sanity, and the more he tries, the more difficult it gets to repress them. The more he fists his cock at midnight, hours after Donghyuck has gone to sleep, and Mark has been unable to wipe the images off from his eyelids, the video film in his head getting more lewd with each passing day, the less ashamed of it he becomes.
And like with everything pertaining to Mark, Donghyuck catches up fast.
Mark can tell Donghyuck has tried waiting it out. Has noticed Mark’s increased hunger for his body. He had held his tongue with a confused frown when Mark had arrived home after work and pushed Donghyuck over the kitchen aisle after their welcome-back kiss had escalated. He had whined– worried about his bladder leaking– when Mark had pressed over his stomach but had let Mark be rougher and greedier.
But the words do not seem to make it past his lips. Even as the guilt and shame ebb away with his growing desire, he dreads a rejection– dreads the possibility of disgust flashing across Haechan’s features. So instead his desire festers and rotts until its stench frays the ends of Donghyuck’s patience.
Donghyuck is an ethereal beauty. Smooth legs that run for miles and thick and sturdy thighs. Upturned soft eyes, a plush wet red mouth, and crooked gentle hands.
In contrast to their actual sub-gender designations, Donghyuck truly awakens something alpha-like in Mark. Fills him with a desire to push Donghyuck into his bed, fill him to the brim with his cock and seed and keep him there, where he belongs. To leave the markings of his presence on Donghyuck’s pretty lithe body and reduce him to tears with only Mark’s omega cock and fingers.
On the other hand, there are times like these, where Donghyuck is cursing loudly into his headpiece, playing his video game in a ratty old t-shirt and sweatpants. Sweaty, brash and overconfident.
This version of Donghyuck is the one from most of Mark’s childhood memories. The sweaty guy who had run beside him during high school track. The kid who had his nose broken and bloody, but had grinned triumphant and smug after fighting another student behind the school in the name of defending Jeno’s honour.
Donghyuck– outside of what Mark has him doing in bed– is a boy, an Alpha through and through. Mischief, snark, and ego embodied into that body and, perhaps it shouldn't, but it turns Mark on so much.
Mark imagines pushing Donghyuck onto the couch, one hand on his neck and the other shoved into his underwear, and watching all that strength fail, and all that ego die faced with Mark’s power and arousal. Imagines smothering out Donghyuck’s complaints of his ongoing game with his mouth and, later his ass, shoving Donghyuck’s face into where Mark runs the hottest until the game is forgotten and his face is coated with omega slick.
Imagines making Donghyuck, Mark’s Alpha, beg Mark for his cock like an omega in heat and denying him. Imagines using his own slick to open Donghyuck and watching the betrayal and desperation flash in his eyes as Mark forces him to orgasm with only his fingers.
And then– and yet still– Mark still wants to take more.
Perhaps it's a sign of how out of hand the situation is getting that Mark only catches on to how wet his fantasies have made him, and the sheer magnitude of pheromones he has released into their space when Donghyuck whips his headphones away from his head and faces Mark with a perplexed look.
“Maark,” Donghyuck croaks, incredulous and appalled, “You had your dick in me thrice within the last twenty hours. Even I'm sore. Are you sure you are not pre-heat?”
Instead of answering, Mark puts away the reading he was supposed to be doing and spreads his legs. And Donghyuck– God bless him– does not need Mark to say it before he closes his setup and makes his way to Mark. Embarrassingly Mark feels another gush of slick leak out.
Donghyuck straddles Mark’s lap, crotches just inches away, and– it's not like Donghyuck isn't heavy. Mark’s alpha is strong and Mark likes that. But Mark is stronger. And Mark likes that even more. Strong enough to push his alpha around. For Mark to be able to fold and hold him down. Or rail him pressed against a wall. Take him wherever and however Mark wanted.
Donghyuck loops his arms around Mark’s neck, pulling the hair at the base to bring him back to reality. Mark takes a deep breath. Perhaps this thing has really evolved into a problem.
Donghyuck kisses him chastely, lips brushing Mark’s soft and gentle, but when Mark digs his fingers into his hips and opens up to press his tongue into the heat of Donghyuck’s mouth, Donghyuck pulls him back with the grip he has on his hair.
“What’s wrong with you?” He questions, his trembling eyes shooting from Mark’s lips to his eyes and then Mark’s heaving chest. “How is a kiss working you up this much?”
“Donghyuck–” Mark whimpers, resisting against the grip Donghyuck has on his scalp and feeling it tighten. Mark simply wants to bury himself in Donghyuck, wants to bite, tear, and reopen the mating bite over Donghyuck's shoulder, wants to– wants to– why wouldn't Donghyuck just let him kiss him?
“Hey, hey,” Donghyuck says, “Whatever it is, why won't you tell me?”
Closing his eyes, Mark groans and reflexively brings Donghyuck's hips closer.
“It's too embarrassing.”
Donghyuck snorts and Mark, unable to help himself, blinks back at him. Donghyuck is warm around him, his weight and his scent the only thing Mark is conscious of. Mirth and amusement dance in his eyes.
“The bikini set at the bottom of our closet would beg to argue otherwise.” Donghyuck relaxes the hold he has on Mark’s hair and settles in closer. “It's not like I'm going to crucify you for wanting to try another new thing in bed.”
A stitch in his chest Mark had not known existed relaxes. The Donghyuck Effect. He makes talking to him so easy, natural, and not so terrifying.
“Come on Mark,” he coos, voice high pitched and teasing, “tell your Alpha what you want.”
God, Donghyuck should not be so forthcoming. Should not be allowing Mark to get away with so much. Mark’s debauchery knows no end. His wolf dreams of possessing their alpha. Of tying him into their bed, and hiding him from the rest of the world. Just a warm and wet hole for Mark to fuck in. Wants him teary-eyed and humiliated. Unable to face Mark but bent to his will and unable to deny him.
Sometimes, the depravity Mark wants to inflict on Donghyuck scares even himself.
Mark’s hesitation must show on his face because Donghyuck's face softens, and he rubs his thumbs over Mark’s temples. “Don’t be embarrassed. It's just me. If I don't like it, I'll say no and we will laugh about it next week.”
And let it be known, Mark tried resisting the temptation. Weak-willed, meager resistance but Donghyuck is loose-limbed and encouraging in his lap and Mark. Mark needs to have him in every way he is allowed.
“Wanna see you take a knot,” Mark breathes out, hurried and out of air. Images flash behind his eyes– Donghyuck with tears in his eyes, rim stretched and red, abdomen distended. An alpha, a strong, broad-shouldered man looming over him, as Donghyucks keens and sings– and wrenches his thoughts away with difficulty to concentrate on the conversation in the present instead. One step at a time.
A surprised, amused giggle rings in the air. “Is that it?” Donghyuck wheezes, “I'll order a knotting dildo now. Was it just–”
The sound of Mark’s hand slapping Donghyuck's phone out of his surprises them both.
“No, don't,” Mark explains uselessly.
“No?”
Mark breathes in deeply and then fixes his eyes on Donghyuck’s face, not wanting to miss whatever reaction his words are about to elicit.
“I want to see you taking an alpha's knot. An actual, living breathing, human alpha.”
Warmth withdraws as Donghyuck straightens to get a good look at Mark. Shifts until he is off Mark’s lap and instead on the couch facing him. If Donghyuck were anyone else, if Mark knew any less better, he would have taken that as rejection. But Donghyuck has always been more forthcoming with his limits and boundaries than with his desires. If Donghyuck was truly against it, he would have outright rejected the idea. But if he is considering it, Mark is certain he can convince him of it. Can make it so good for him.
Instead Mark shifts as well, so that Donghyuck can continue the conversation.
“You want to have a threesome?” Donghyuck laughs uncertainly, eyes darting across the room. Donghyuck looks confused, uncertain, and out of depth. Mark drinks his expression in as Donghyuck tries to weigh the idea and adjust to his concept of reality. Experiencing– no, eliciting this discomfort feels almost as good as fantasising about putting him through this.
“You know that's not what I mean,” Mark says softly, nudging their knees together.
A pause and then, more vulnerable and a tad incredulous, Donghyuck says, “You want to share me?” pointing shakily at his own chest.
Mark hums and cups Donghyuck's cheeks, “Only if you want to. If you don't–”
Donghyuck shakes his head, “No it's like–” A confused cute furrow appears between his brows and Mark’s heart bursts with a surge of affection, Donghyuck is so cute, “I don't understand what's in it for you. You never liked when people looked at me for too long and now you want to be cucked? It's just out of character so–”
Donghyuck is not wrong. A little while after their presentation and Mark’s growing pining, it had become unbearable to watch people throw themselves at Donghyuck. Jealousy and fear of losing him had Mark on the edge even before they had started going out. Possessive arms around Donghyuck’s waist, clinging to his back during group studies. Scenting him, dousing him in burnt-heavy caramel pheromones in school bathrooms and at the club where Donghyuck sang. Hickies and bruises like a feral animal over his neck and the entire length of his legs, following under his shorts after they had gotten together.
Despite the mated bite on Donghyuck’s shoulder visible and out, Mark still frowns at the memories.
“I still am like that. I don't like when people question what's mine.” Mark digs his thumb into Donghyuck’s lip, and the latter presses his teeth into it before moving away slightly to speak.
“See so, cucking is so out of char–”
“It's not cucking,” Mark complains, shoving playfully at his shoulder. “It's more of– I don't get off on the idea that another alpha is stronger than me or them pleasuring you more than I can at all. It's about them being considerably stronger than you. It's about you going through with it, about you being aroused by it because you know it turns me on, you know?”
Something so delightful about pushing Donghyuck as far away possible from his biology and his instinct as he can, just because Donghyuck allows Mark to.
“Oh,” Donghyuck says and he flushes so extensively that Mark’s palm warms up. His eyes fix at a point behind Mark’s shoulder, flicking periodically to Mark, as he comes to terms with the idea in his own head. Mark moves his thumb back to Donghyuck's mouth, shoving it deeper this time, watching it indent his plush lip, the pressure turning it pale, and lets the topic drop for the time being.
When Mark had presented, everyone had dubbed it a freak presentation. His mother had dragged him to the doctor after he had his heat at fourteen, worried that her son was headstrong, stubborn, and wilful. He was prone to picking fights and never knew when to give up. To her, it had sounded like no omega she had known. Mark had her telling the doctor after he had been sent outside, that she was anxious about the pressures an omega faces. Mark’s personality matched an Alpha but so did his skillset.
And Mark knows she was thinking about how he had burnt his ramen charcoal black last week. How he feared how tiny his niece was, and how incapable he was at looking after her unless Donghyuck was around.
So he had understood where she was coming from. He too, like everyone else, had been sure he would present as an alpha. Did not know why his body was all confused and pushing out slick. Why had it decided to subject him to this.
Years later, he had realised his body and subconscious had known him better at the age of fourteen. Mark downright relishes being one. He loves watching other men trip over their feet to woo him. He adores being the only omega in their group and still having all his friends look to him for help and guidance. Likes crushing an overeager new coworker's ego when they find out Mark is better in the company at everything and more than they can do. Mark loves being competent enough for them to take him like a competition after they have tried to mansplain and posture, and loves being strong enough for his threats to hold weight when they inevitably toe out of line. Mark loves having these stereotypes and revels in the reaction it brings out of people– Surprise. Anger. Vexation– when he steps around them; graceful and easy.
Mark loves the knowledge that he is, without actually trying, a better Alpha than most of the actual alphas out there.
What Mark also really likes, as superficial and sex-addled as it may sound, is having the power and the command to hold and push around alphas, despite being an omega himself. Loves that he can have an alpha at his feet, going against all their baser hindbrain instincts, and begging Mark for his cock. Loves his alphas desperate, powerless, and humiliated because they know that's how Mark likes them.
Perhaps, that's why taking from Donghyuck, reducing him to such, when outside their bed and activities Donghyuck is a menace to everyone around him, brings Mark incredible joy. Donghyuck is at home in his skin, and has a little alpha ego, but is self-assured and cocky. He is certain about what he wants and how he wants it and yet dabbles in debauchery against himself because he knows it arouses Mark. And while for Mark, most of the arousal stems from the boy beneath him being Donghyuck, the implications of having an alpha by its nape and pulse bounding under his fingertips as it fails to resist Mark’s strength drives Mark’s hindbrain feral.
Mark finds being an omega so fun.
Donghyuck does not bring the topic up again. So Mark does not press it. Or tries to. But it is difficult to not tease Donghyuck when he turns a pretty shade of red when Mark leaves an alpha on alpha porn open on his laptop for Donghyuck to find. When Donghyuck moans louder and grips his cock tighter when Mark tells how loose his rim will look after being knotted. Donghyuck is so easy for him.
It's easier still to tease him because Mark and Donghyuck both know Donghyuck will say yes. The longer it takes, the more certain it gets that Donghyuck needs time to get used to the idea in his head and to prepare himself. So Mark enjoys Donghyuck’s subtle shame and embarrassment and lets his boyfriend come to him when he is ready.
“Would you have liked us to be the opposite instead?” Donghyuck asks him a few weeks later, stirring the almost done pot of kimchi jjigae, while Mark floats around the kitchen trying to be useful.
“Opposite? Like what?” Mark replies, absentmindedly at first, and then, after Donghyuck’s words catch a beat later, he follows, smug and gleeful, “As you hoped we were when you were younger?”
When Mark had presented, far too early and young, Donghyuck had spent weeks following him around. Snotty, short kid with anxious darting eyes across the school, lip caught between his teeth, and white-knuckled fists around the straps of his bag. It had taken Mark screaming at him, ashamed and mortified, telling him Mark suddenly did not need his protection, for things to ease between them. Donghyuck had been as sure about presenting as an omega as he had been about Mark being an Alpha and Mark’s presentation had thrown even a young Donghyuck into a frenzy.
Years down the row, their friends had teased that Donghyuck had presented forcibly as an Alpha just so that his young crush could have stood a chance. But Mark knows now that Donghyuck and he could have been anything, and they would have still ended up here. Mark had just been a little late to catch up.
Mark walks back and wraps his arms around Donghyuck’s waist, pulling him closer into Mark’s front, and breathing him in. Lavender. Boy. Alpha. Mark feels before he smells his own pheromones release with a sudden burst as Mark digs his nose into Donghyuck's scent glands over his neck to cover him with Mark’s.
“Nggh– hyung.” Donghyuck’s body, from his core down to where he is white-knuckling the spoon, trembles.
“What? Did you want to be my omega whore Hyuckie?” Mark raises his mouth to his ear to whisper, as his hands spread over Donghyuck's lower abdomen, right where– “Do you fantasize about it? My child in your belly and another at your hip? Bumbling around in the kitchen and spending your days waiting for me to fill you up with me seed?”
Mark laughs when Donghyuck's breathing picks up and he grows quieter. Cute.
“Nah, I quite like being the omega being that fucks up their alpha you know,” Mark tries for more casual but it comes out hushed and teasing, “Love when assholes assume that I'm being railed by you when I know you are sitting next to me with my cum plugged up your ass.”
Even imagining it has Mark chubbing in his shorts. He tugs Donghyuck into himself even tighter, settling his cock in the space between the younger’s ass. Kisses his ear and asks, “Do you?”
It takes longer for Donghyuck to formulate a response, his brain cockdrunk with only a few words. So easy.
Donghyuck pulls a few deep breaths, laces together the hand that isn't stirring the pot with Mark’s over his stomach, and confesses, “Some– sometimes. I– imagine being wet and easy for you. Wish you could– could slide right into me. Didn't have to take long with the prep.”
Mark laughs, even more delighted. God fashioned Donghyuck just for Mark it seemed. He kisses Donghyuck's ear with a loud exaggerated mwuah, before trailing his lips down his neck. Donghyuck instinctively stretches his neck to give him room.
“On the contrary, I love opening you up,” Mark says, in between kisses, “Using my slick to stretch you loose.” Another loud kiss, and hands creeping lower, “Using your hole which isn't meant to be taking a cock, much less an omega one.”
Mark lays a final kiss over the scent gland and roughly grabs over Donghyuck’s shorts to hold his half-mast. Donghyuck squeals and goes on his tiptoes, pushing his shoulders back into Mark, nowhere to go.
“See, Hyuck it doesn't matter if I was a beta or an alpha. I can rattle you just fine,” Mark tells him, tightening his grip over his cock to highlight what he is saying, “Doesn't matter if you were born an alpha or an omega. You take my cock as if you were born to be hanging off it.”
Donghyuck sucks in a breath, and Mark catches his ear between his teeth, taking his time nibbling and sucking on it. He relaxes his grip over Donghyuck’s cock and skims his fingers over it instead. Playing with Donghyuck like a cat with food.
“I'm going to burn the food,” Donghyuck whimpers, writhing in his arms, unable to decide whether to avoid the stimulation or lean into it.
Mark smirks into his neck, and with a last kiss, says, “Oh no, we can't have that.” and withdraws completely.
Laughs even harder when Donghyuck looks at him betrayed and angry. “Sweetheart, concentrate on the food, I'll put up the plates. We do need to eat.”
Once they are on the table, have dug halfway into the food and Mark has finished crying praises over how good it tastes, Donghyuck picks up the conversation. Swirls his spoon in the soup and asks without looking at him.
“Whose,” another deep breath, and because he is a boy and an alpha, he says crudely and off hand, “Whose knot do you want me hanging off from then?”
How adorable, Mark thinks condescendingly. Donghyuck thinks he can rattle Mark with his arousal, using his weakness over a casual dinner, like Mark had been playing with him in the kitchen. Most days, Donghyuck does succeed in getting an initial upper hand, and Mark loves the bratty side as much as he likes taming it.
However, this time, an eager, impatient answer has been on the tip of his tongue for weeks.
He tastes it and revels in the knowledge of what he expects it would do to his pretty, oblivious mate and his calm composed facade. He feels his mouth stretch into a feral grin, one that is less his and belongs more to the name that slips out of his lips, smug and greedy.
“Jaemin.”
The reaction is as delicious as Mark had expected.
Donghyuck’s spoon falls from between his fingers back into the spoon with a splash. He is not breathing when he looks back at Mark; eyes wide and off guard. A naive innocent deer caught in the headlights.
Mark watches hungrily, arousal curdling in his abdomen, getting high on the possibility of what the physical presence of the man will do to Donghyck if the name is enough to yield this.
Mark watches ravenously as Donghyuck’s expression shifts from shock to disbelief to betrayal to utter instinctive rejection of the idea. Watches Donghyuck’s eye twitch and his hands fist into his shirt, pulling at it for comfort. As his stalled breath picks up again, this time into struggled heaves as Donghyuck considers the idea and, against all sensibilities, imagines it.
“Na Jaemin,” Donghyuck says, at last, punched out words, breathing unevenly.
“Na Jaemin,” Mark agrees easily and self-satisfied. He swirls his spoon into the soup but does not look away. Does not give Donghyuck the courtesy of space to pull himself back together.
“Our Na Jaemin?” Donghyuck hisses back stronger this time, “You fantasise me stretched around Jaemin’s knot?”
“Yeah. Fantasise you sobbing on it. Taking it like a good boy,” Mark agrees easily, knowing that his apathy to this will bring the most out of Donghyuck. “About you losing to him, and giving in.”
“Your nasty fantasy is me being a loser?” And yet, there is no betrayal, no anger in his tone. Instead, it is appalled and curious.
“What can I say,” Mark shrugs, “you win too much.”
Because Donghyuck truly does. Anywhere he goes, Donghyuck outshines everyone else. The prettiest. The funniest. The most well-spoken. The most well-coordinated. The most competent. Perhaps that is what makes crushing him between his hands so enjoyable. Why Mark’s hindbrain is on the outlook for new creative ways to bring him a peg down.
“Hyung,” this time it's a plea, a whine, and a whimper mixed into one. “Jaemin, really? Really? He is–”
“He is what?” Mark questions, just to be difficult. Because Mark understands. Knows that Jaemin is the only one willing to go toe to toe with Donghyuck and match Donghyuck’s wit. The only one who can occasionally come out victorious.
With Mark, Donghyuck willfully surrenders. Let Mark’s sincerity and, at times, his unsubtle untamed desire dismantle him. But Jaemin gives Donghyuck no leeway, no way out. Has Donghyuck conceding far before he is ready to. With Jaemin, another alpha and someone who is only competitive against him, Donghyuck’s alpha pride is more sensitive and more prone to taking a hit. And that is why Mark’s hindbrain deems Jaemin the ultimate option for this fantasy.
Donghyuck must be picturing it too, because his lavender scent thickens and turns heavy in the space between them. His aroused pheromones mixing with Mark’s feel like a sweet, hard-earned victory.
Donghyuck, with ruddy cheeks and skirting eyes, changes gears.
“Alphas aren't meant to be taking other alphas. It's not easy,” he whines, just to escape addressing the elephant in the room, “It's nothing at all like porn makes it–”
Mark latches onto the fact that Donghyuck has watched enough alpha-on-alpha action to draw these conclusions for a later time and instead moves to other matters.
“And? This wasn't a complaint ten minutes ago”
“So is it the humiliation aspect of it? Or the power?” Donghyuck turns on him next, “Not enough that I– that you– that I do it for you, but it has to be Jaemin now?”
Mark drinks two mouthfuls of the soup before answering, calm, assured, and eyebrow raised. “Why can't it be both?”
Donghyuck’s mouth opens even further, eyes lost and dilated. “You like– you want–”
“I do.” Mark fixes him with a confident look. Donghyuck's scent has turned so dense, that if the conversation does not end, Mark is scared he is going to throw himself at Donghyuck and take him at the table, exactly inches from where they are sitting, food eaten or not.
“Hyung,” Donghyuck whimpers and Mark takes in a lungful of air before asking, “Yeah?”
Donghyuck still looks at him like that, eyes so wide and deer-like, and legs clenched and visible up to his upper thighs. Delectable, ready to be corrupted. And it takes all of Mark’s willpower to stay on track with the conversation and not settle between his legs and dig his teeth into–
“Come on Hyuckie,” Mark says, stretching his arm and holding it palm up for Donghyuck to take. “If you really don't want to. If you really don't want Jaemin to be an option, you would have said no already. Actually, say no now and I won't push it but you have to tell me no. Be direct with it. Come on.”
Donghyuck’s hands clench into his shorts. Whines, a sharp needy sound from his throat. A pregnant expectant pause hangs in the air and then Donghyuck reaches out, taking Mark’s hand and mumbling, defeated into his soup. “He won't agree.”
Every atom in Mark rejoices and the rush of blood in his ears makes them ring in anticipation.
“Oh no Donghyuck,” Mark smiles feral and victorious, “I know he will.”
