The waiting room of the doctor’s office is freezing. You pull on the sleeves of your sweater, trying your best to stretch them over your hands. When it doesn’t work, you huff and lean back in your seat. You glance around the room, arms crossed against your chest. At the desk, the receptionist types aggressively on her keyboard. In the corner, there’s an omega with an infant in her arms, who coos loudly every few minutes. There’s an older man a few seats down from them, who is seemingly asleep. His head lolls to the side and soft snores escape his lips from time to time. The bell on the door dings as another couple walks in. One man walks up the counter to check in. The other sits down and is clearly in the middle of an intense phone conversation, if the half-whispered, angry words leaving his mouth are any indication.Â
You lean your head back to rest against the wall and let your eyes drift closed. It’s been over 30 minutes since you’ve checked in and, needless to say, you are a little overstimulated. After a few moments, you feel fingers brush against your knee over your jeans. Your leg instinctively stops bouncing, though you didn’t even realize you were doing it in the first place. Opening your eyes once more, you see Nicho’s free hand lightly resting on your thigh now, just above the knee. “Relax,” he whispers to you, eyes still not leaving his phone.Â
“Sorry,” you mutter, chewing on your lip. “Just nervous.”Â
He gives your leg a gentle squeeze. “It’s okay.”
You lean over his shoulder and see that he has Euijoo’s location pulled up. The alpha’s profile picture, one he secretly took of you and Nicho draped sleepily over each other in the nest, hovers over his work building, completely unmoving.Â
Nicho catches you looking at his phone and frowns. “I don’t think Juju’s going to make it, tiánxÄ«n,” he murmurs. He leans over to press a chaste kiss to your temple, as if apologizing.Â
“It’s alright,” you whisper, leaning your head against his. Though you can tell from the crease in his brown that he doesn’t quite believe you.Â
You don’t have much time to dwell on it, because the door to the back clicks openly sharply and your name rings out into the waiting area. Nicho gets up first, pocketing his phone before helping you up out of the chair. He makes small talk with the nurse as she leads you both back to an exam room.Â
The next few minutes go by in what feels like a blur. The nurse takes your vitals and asks about your medical history. You answer as best as you can, with Nicho chiming in every once in a while when you feel a little too spacey to come up with a response. She finally leaves the room with the promise that the doctor will be in soon.
You can feel the weight of Nicho’s gaze from across the room, so you busy yourself with picking aimlessly at the paper on the exam table. He says your name once, gently. You hum, but don’t look at him. He says it again, this time with a little more force. Reluctantly, you lift your head to stare at him.Â
“You’re thinking too much. Stop stressing. It’s going to be fine,” he says, his tone vaguely reminiscent of Euijoo’s alpha voice. But as much as he tries, it’s never going to have the same effect as the alpha’s actual words. Your body relaxes, but only a smidge.Â
“What if it's not fine though?” you ask hesitantly.Â
He sighs and sits up straighter in his chair. “That’s why we’re here. We’ve talked about this.” His tone is sharp.Â
“But I don’t want you to feel like you have to…” you trail off as the door to the exam room opens.Â
Your doctor strolls in, a happy grin on her face. “Hello, hello! Good to see you as always!” she chirps. She glances around the room and pauses for a moment. “Just you two today?”
From the corner of your eye, you can see Nicho frown once again. “Euijoo’s at work,” he concedes.Â
She nods, clearly aware of the uncomfortable air that has settled in the room. She sits down in the rolling chair and slides forward a bit. “So, what brings us in today?”
You begin to fidget with your clothes. “We’re uh…,” you glance over at Nicho who gives you a nod of encouragement. “We’re ready to start trying to conceive, I think.”Â
Her eyes light up immediately. “Really? Oh that’s great! Wow, has it really been that long? It feels like just yesterday you were mated.” Which is a fair question if you’re being honest, because she’s been your doctor since before you three were even dating. You nod shyly.Â
“Alrighty then,” she says, crossing one leg over the other. “How are we planning to…go about this then?” she asks, waving a hand between you and your omega mate.Â
Her smile is still bright, so you steel your nerves and continue. “Nicholas is nervous about the whole…concept of pregnancy, I guess. So we decided that I would try and get pregnant first, so that if he eventually decides he wants to have a baby himself, he knows what to expect.” You pause for a moment, letting her take in the information. “We’re here today because we just want to make sure I'm healthy and everything. That my body is ready for it.”
“Well,” she says, “let’s get started then.”
A few hours later, Euijoo finds you and Nicholas cuddled up on the couch, fast asleep. A stack of pregnancy related pamphlets sits on the coffee table and he pretends to ignore their existence. Frankly, the fact that you both look exhausted and his own overwhelming guilt are more pressing matters. He tried so hard to get off work for this appointment, but his clients had last minute changes they wanted done before the deadline tomorrow. The guilt ate him alive all day as he watched the hours tick by, knowing that you and Nicho would be sitting in that cold, sterile doctor’s office alone.Â
You had been vulnerable with him a few weeks ago, voicing your anxiety about the appointment. And stupidly, he had promised that he would find a way to get the time off so he could be there with you. He should’ve known better than to make a promise he couldn’t keep.Â
Euijoo can see the sticky residue of a scent-blocking patch peeking out from underneath Nicho’s collar. The skin around the area is red and puffy. He must have used the regular patches instead of the ones made for sensitive skin. Euijoo makes a mental note to grab another box at the store tomorrow.Â
In the meantime, he pads toward the bathroom to grab some itch relief cream. He stops in the bedroom for a moment to change into comfier clothes. There’s a 99% chance the t-shirt he put on is actually yours, based on the clean, cottony scent emanating from it. Though at this point in your relationship, it’s yours just as much as it’s his and Nicho’s.Â
When he finally returns to the living room, you’re awake and scrolling on your phone. You clearly know he’s there based on the way your eyes flick up when he crosses the threshold, but you don’t give him the liberty of a greeting. Fair enough, Euijoo thinks to himself. I would be mad at me too. Â
After a moment, he wills himself to finally approach the couch. He squirts a bit of itch cream onto his finger and deposits the tube on the table. You watch silently as he kneels, pulls back the neck of Nicho’s shirt, and lightly dabs the cream onto the inflamed area.Â
At first, you don’t say anything. You simply stare at him in silence. But once he’s done and is wiping his finger on a paper towel, you speak up. “I told him we had time to pick up a new box before the appointment, but he refused.”Â
Yeah that’s not surprising at all. It’s exactly something Nicho would do. But the way you say it makes it sound like an apology. Like you’ve been carrying the guilt of that action all day. You and Euijoo are more similar than it may seem.Â
“It’s okay,” he shushes you. He’s silent for a beat, and then, “I’m sorry I couldn’t make it to your appointment.”Â
You seem to stew in your thoughts for a second before responding. “I forgive you. I know you wouldn’t have missed it without a good reason.”
He nods. “Did it go well?”
“Yeah. She said I seem perfectly healthy. Just waiting to hear back about my bloodwork results. If everything looks good, we can start…trying…whenever.”Â
It doesn’t matter how long you three have been together and how much sex you’ve had, any mention of getting pregnant makes you stumble over your words. It’s an endearing trait that Euijoo has come to adore over the past few months of discussion. You very rarely get shy with them anymore, so it’s nice to see that side of you again. He reaches out to cup your cheek. “That’s good. Do you think you want to wait until our cycles? Or start sooner?”Â
You frown a little bit and Euijoo takes a second to admire the scrunch in your face. “Start sooner I think? I don’t want our cycles to feel like a chore. Like it’s something we have to do and not something we want to do.”Â
He can’t help but agree with what you say. “Okay, we can do that,” he says, brushing a thumb against your lower lip to stop you from biting it. “Just tell me when you’re ready.”
Less than a week later, Euijoo strolls into the kitchen and drops an envelope onto the table in front of you. You stare blankly at it for a few seconds before your brain processes the health center logo. Blinking a few more times, you push the envelope toward Nicholas, who sits across from you. He raises a brow questioningly at you. “I don’t wanna open it,” you murmur, just loud enough for him to hear.Â
Initially, he rolls his eyes. But eventually he gives in and tears it open. He glances over the paper quickly before smirking. “Clean bill of health. No concerns,” he says proudly.
“That’s great,” you hear Euijoo say from the kitchen. “So we can start trying whenever?”
You stare down at the table in front of you. “I guess, yeah,” you mutter.Â
Euijoo’s stare bores into the back of your head. “What’s wrong?” he asks, stepping closer to you and Nicholas.Â
“Nothing’s wrong,” you say, still avoiding eye contact with either of them.Â
You can hear Nicho scoff, and then the chair next to you scrapes the floor as Euijoo pulls it out to sit down. He reaches out to brush his thumb against your cheek. “Seriously, what’s wrong? I know you were nervous about this appointment, but this is exactly the news we wanted to hear.”Â
God, he’s way too gentle for an alpha. How did you manage to bag him and Nicho? “I, uh,” you begin. “It’s just a little too real now, I guess. It’s kind of…daunting.”Â
Euijoo hums and pushes the collar of your shirt down to run his wrist along the scent gland on your neck. You nod, a little drunk on the feeling. Or maybe that has something to do with the soothing pheromones Nicho has been releasing. Either way, it calms your nerves. “It is a lot to think about, huh? Don’t worry too much about it right now. We’ll take it slow. Nothing has to change much right now. We can let everything happen naturally. And if something happens, we’ll face it all together, alright?”Â
Once more, you nod. He scents you for a little longer, before standing up and ruffling your hair. “I’m going to shower. If you’re still nervous, you can talk it over with Nichol.”Â
You watch as the alpha pads back toward your shared bedroom. The air is heavy and silent in the room now. You try your best to focus on your phone again, but Nicho’s eyes never leave you. You squirm under his gaze until you can’t handle it anymore. “Why are you glaring at me?”
He’s squinting at you like you’re a puzzle he’s trying to solve. “There’s something else that’s bothering you,” he says sternly.Â
Damn him for knowing his own mate too well. “No there’s not,” you counter.Â
“I can tell by your scent that you’re lying,” he deadpans.Â
You stare defiantly at him. He stares back blankly and you know this is a battle you’re definitely going to lose. Nicho is nothing if not stubborn. “I’m just worried that we’re going to be neglecting you during this process, I guess. I want trying for a baby to be fun for you too,” you admit.Â
“Baby, I think I could cum untouched just from watching Juju fuck you.” You breathe a sigh of relief, but are quickly concerned again when he flashes a mischievous smile at you. “But don’t worry about me. I have an idea.” Nicho and the word “idea” should never occur in the same sentence, especially when it comes to sex.
And that’s how you find yourself in your current predicament a few hours later.
You’re naked on your back, legs spread wide and held down by Nicho’s arms. He’s lapping furiously at your cunt, like he’s been deprived of this his whole life (spoiler alert: he has not). Euijoo kneels behind him, brows furrowed in concentration and tongue poking out as he fingers the omega open.Â
The alpha must hit the right spot, because Nicho pulls back and lets out the filthiest moan. “Yeah?” Euijoo asks with a smirk. “You think you’re ready?” The omega nods furiously. You hear the crack of a hand coming down on skin and a yelp that follows moments later. When you look up, Euijoo is softly rubbing the curve of Nicho’s ass. “I didn’t say stop, did I? Don’t leave our girl all neglected.”
Before you can even register the words, the omega dives right back in. Plush lips suck harshly at your clit and you whine. From somewhere else in the room, you hear Euijoo shushing you. Hypocrite you think to yourself. He’s so loud when he’s not domming. Nicho pulls you out of your thoughts with a few more harsh sucks and your orgasm hits you like a freight train. Your eyes roll back and everything goes quiet. The only thing you feel is overwhelming pleasure.
When you finally come back to, Nicho is still above you, though he’s panting softly. The telltale rock of his hips and the reappearance of Euijoo behind him tells you that the toy has finally been brought out. After a moment, the omega gasps and a loud pop fills the room.Â
“Oh god it’s bigger than I remember,” he rasps. You can see the alpha’s pitiful pout from over Nicho’s shoulder. The room is quickly filled with the stench of displeased alpha, so the omega quickly corrects himself. “Not bigger than you though, Juju.” The acrid smell begins to fade immediately. Typical alpha.
“Up,” Euijoo says, tapping lightly at the skin of Nicho’s hip. Gently as though to not shift the toy now nestled in inside him, Nicho crawls up the bed to lean against the headboard. You shuffle to rest between his legs. Your alpha plants his hands on either side of you and you look up to meet his eyes. He smiles gently down at you. “Hi baby,” he says, leaning down to kiss your forehead. “You ready?”
You nod eagerly and glance down between your bodies. His cock hangs heavy between you, thick and red and pulsing from lack of attention. You wrap your arms around him as he hikes one of your legs up, before pushing himself in. It feels as if he’s going agonizingly slow on purpose and you feel yourself getting antsy with need.Â
When he finally bottoms out, you sigh with relief, knowing that he’ll fuck you soon. But instead of moving, he pauses. “Juju, please,” you whine, nails clawing at his back.
He winces a bit at the sting. “Give me a minute, baby. Just wanna look at you for a moment.”
“He’s just holding off because he’s about to cum just from the idea of breeding you,” Nicho whispers dirtily in your ear.
Euijoo shifts his weight so he can reach up and pinch the omega’s thigh, who yelps in response. “Brat,” he mutters. Then, he leans over to where his phone rests on the bed and clicks a button. You hear the toy begin to faintly buzz and Nicho reacts with a broken gasp.Â
With the omega preoccupied, Euijoo finally moves. He pulls almost all the way out before plunging back in. The feeling is delicious, the slide smooth and languid from your earlier release. Within a few thrusts, he finds your sweet spot and you can't help but shudder. And your mates know that response a little too well, because Nicho pulls your leg up higher while Euijoo smirks.Â
But two (three, you suppose) can play at that game. You reach out to where the alpha’s phone sits and move the slider farther to the right. The toy’s buzzing gets even faster and Nicho’s hips buck up against you. You can faintly hear him whisper, “fuck.”Â
A hand lightly grazing your nipple pulls your mind away from the momentary win. You suck in a sharp breath at the unexpected feeling. Nicho fingers twirl delicately around the bud and he must have licked them right before because they’re fucking wet. He tweaks it again, less gently this time and you hold back a moan. “Juju’s gonna love how big these get when you’re pregnant,” he says with much more composure than you were hoping for. “Right Jju?”Â
When you look up, the alpha groans and nods enthusiastically. His pupils are blown, eyes almost entirely black rather than their normal chocolate brown. There’s sweat dripping down his temples and his mouth hangs open, panting. He makes a particularly deep thrust and you gasp, reaching out to grab Nicho’s free arm. He wraps himself around you even more in response and leans down to press a kiss to your head. “Shhh, you can take it,” he mumbles into your hair. “I know you can.”Â
The hand on your breast trails down, farther and farther until it reaches where you want it the most. He teases you at first, fingers ghosting over your clit for a few seconds. Then he dives in, circling it just how you like. And you swear the alpha and omega are telepathically connected because, at the same time, Euijoo finds the perfect angle, ramming into your sweet spot over and over.Â
You’re too preoccupied with the intense pleasure to notice Euijoo leaning over to increase the speed of Nicho’s toy once more. The room becomes hot and heavy, the sound of various groans, cries, and gasps filling the air. Euijoo’s knot is just starting to swell, catching on your walls as he continues to thrust shallowly. Nicho is hard and throbbing behind you, eagerly grinding against your back. You feel yourself getting closer and closer to the edge and you’re egged on by the thought of your two mates being just as close.Â
The final straw is your alpha leaning down to kiss and suck at the mating mark on your neck. You quiver as your climax hits you, and you feel yourself contract against Euijoo’s rapidly expanding knot. He mumbles something against your skin, though the pleasure makes it too hard to hear what he’s saying. You do notice the way one of his hands reaches over to the phone. You have half a mind to realize he pushed the knot button on the toy’s app, if Nicho’s cries and the stickiness along your back are any indication.Â
Euijoo’s knot finally expands all the way and he twitches inside you as he releases. He drops more of his body weight on top of you and your mind blanks out. You can’t feel anything but full, full, full.Â
After a minute or so of bliss, you come back to the world of the living. Euijoo has flipped you both over to your sides to lay more comfortably while tied together. Nicho’s still behind you, one hand petting your hair gently, the other palming over the small bulge in your lower abdomen. “I think our little alpha has a breeding kink,” he whispers into your neck.Â
Euijoo’s face, red from exertion, flushes impossibly more. “No I don’t!”
“It’s alright if you do Juju, it’s hot,” the omega teases him. “I don’t think I’ve seen you cum that much since the first time you knotted me.”Â
The alpha buries his face into your neck. You brush some stray hairs off his forehead, sticky with sweat. “It’s okay, I liked it,” you reassure him.
The room falls into a comfortable silence as everyone catches their breath. You can’t help but wish you could pause time, sit here with your two mates forever. But you’re soon interrupted by Euijoo pressing his hand overtop the same spot that Nicho’s lays. “You think it will take?” he mumbles to no one in particular.Â
You hear Nicho laugh sharply behind you. “Definitely. You gave her enough to have a whole litter at once.”Â
You can know the exact moment that Euijoo processes the words, because his cock twitches inside of you. “Byun Euijoo!” you scold, smacking him lightly on the chest.
“I’m sorry,” he stammers, hips wiggling against yours. “I can’t help it.” Your body responds by clenching down on him and he chokes on air. His knot throbs and you writhe at the feeling.Â
Nicho giggles behind you, clearly pleased with the predicament his two mates are in. So, you lean back to pinch his thigh. “Stop it or I’ll make him put a baby in you too,” you grit out from between your teeth.
But he takes both you and the alpha (and himself, a little bit) by surprise by letting out one of the loudest keens he’s ever produced. “Well,” you mutter. “That’s a can of worms we can open later. Maybe during round two?”
