Placebo

REQUEST: Hey! Listen i loved the omega verse requests. But then I was also thinking what about the opposite? Like R is an alpha taking suppressants. And unknowingly she gets off it around the same time yukio is in heat. So Ellie is like this is a shit show and is trying to help R who’s panicking and yukio who just wants both alphas (cuz in yukios mind she’s like finally I can get double the pleasure)

SYNOPSIS: You're the ultimate alpha -- that's your superpower. The downside is, most suppressants are no match for your instincts and urges. You've found a solution in the form of an experimental suppressant being tested on yourself and others like you. Just as you've gotten used to your newfound peace, the meds suddenly stop working. What's worse? Yukio's in heat.

Warnings/Notes: A/B/O, Yukisonic x Reader, Porn With Minimal Plot, Your Past Sexual Experiences are Dubiously Consensual, I Don't Care What Typical A/B/O Dynamics Are - I Do What I Want, Reader (Accidentally) Self-Harms, Lots of Oral, Penetration - Yukio!Receving & R!Receiving and Giving

The ultimate alpha. Stronger, faster, better hearing, better sense of smell, stronger smell, more in tune with your natural instincts… That’s your mutation. Pretty lame compared to reading minds, healing touch, or wings, but it’s yours, and it’s enough for you to be looked upon with distaste by the anti-mutant crowd.

Normal suppressants don’t work for you – they’re only meant to bring an alpha down to socially-acceptable levels of their innate traits. For you, that would only put you at the level of an alpha without suppressants. Thankfully, though, there’s hope. You’re part of a medical trial with some other alphas who have overactive traits. None of the others are quite at your level, of course, but it’s working nonetheless, and it has been for the past few years.

You take your pill as needed, no more than one every four hours. Today, though, you’re two hours in and you’re ready to claw Ellie’s eyes out for having your omega the way you’ve always wanted her.

For omegas, suppressants can cause infertility if they don’t take a break every three months or so, so every now and then Ellie is lucky enough to get to help Yukio through her heats, while you stay away in your old bedroom for the week. You’re too afraid to lose control and give her your bite, something she wants to wait for until marriage, or in the case of the three of you, a commitment ceremony. You’re in full agreement on that, in fact, you wish you didn’t have the bites you do from that period of your life before medication where you had little to no self control. You wouldn’t be surprised if you had a kid or two already, though no one’s reached out.

It’s the last day of her heat. You sulk in the kitchen. You hoped eating would distract you, but the apple in your hand has been crushed. You eat it anyway, trying to ignore your disgust at its new texture.

Ellie strolls in, a little flushed and reeking of Yukio’s sweet scent. She smells so much like an omega that you almost want to mount her right then and there.

“Babe, are you alright?” she asks. “You know you can join us, right? I’m willing to keep an eye on things. ”

“I- I think something’s wrong,” you realize. “It’s not- The medicine’s not- I need to be locked up or something, like before.”

“Really?” Ellie rushes to your side, pressing the back of your forehead. “Fuck, you’re burning up.” She blinks, looking dazed. “You smell, like… Oh, shit, they’re not doing anything at all, are they? It’s so strong, even I want… Shit.”

She racks her brain for a minute or so, her eyebrows furrowed in concern.

“We should take you to the bedroom, okay?” she decides, surprising you. “I got something for you a while back, but, I don’t know, you started talking about hating being an alpha in general and I didn’t think you’d want it.”

“What is it?” you wonder.

“A muzzle,” she nervously says, adding with tentative excitement: “No bite risk.”

“Well, that is the number one hurdle,” you admit, feeling your member already starting to extend with her proximity to you. “But then, there’s you to worry about. I don’t want to hurt you.”

“I can handle myself. I’ve thought of more than a few ways we could share that you’d like. Let’s… Let’s give it a shot, okay?”

You can smell her fear. Fuck, it smells so good, like fresh strawberries. You can taste it. You cover your mouth and nose, your eyes watering with tears full of shame. You love Ellie, her terror shouldn’t appetize you.

“It’s okay, baby,” she whispers. “Come on. I’ll grab some more water, then we’ll go.”

Despite her anxiety, she leads you by the hand to the bedroom. You’re trembling. It’s everything you ever wanted and yet you’re so filled with self-disgust for feeling that way – your instincts make you hate yourself for being okay with sharing, your love for them both makes you hate yourself for being such an animal.

She knocks softly on the door.

“Yukio, I’m back. I brought a surprise for you,” she tells your shared mate as she opens the door. You hesitantly enter after her, and Yukio’s mouth falls open. “Easy,” she warns, but you’re not sure who she’s warning until she continues: “Y/N’s medicine isn’t working. She needs our help. Your help especially. Are you up for that?”

Yukio nods as Ellie opens up the black chest where you all keep your collection of toys. She reveals the muzzle, and a growl rumbles in your throat.

“Sorry, sorry,” you quickly say.

“I’ll do it,” Yukio offers, getting up from the bed. Sure, you’ve seen her naked before, but never dripping slick down her thighs and radiating pure need. She takes the muzzle from Ellie, meeting your eyes with a sad smile as she approaches you. She caresses your face first. You shudder, torn between closing your eyes and enjoying the sensation of your omega touching you and keeping them open to look at her pretty face. You’re painfully hard.

The muzzle is more of a leather cage, so thankfully you’ll still be able to smell and maybe even taste certain things, as a finger can fit through the holes. Yukio gently presses it to your face, and you secure the straps.

“I almost don’t even want this,” she says softly. “Putting this on you like you’re some sort of reactive dog feels wrong.”

“I’d feel worse if I bit you,” you disagree. “It’s okay. It’s kind of comforting, considering- I’m so close to losing it, I-” You don’t know what to say next, thoughts are escaping you one by one as you look into your omega’s eyes. You feel like one or both of you is gonna die if you don’t get started soon. She nods in understanding, stepping back before reclining on the bed.

“Do you need help with the condom?” Ellie asks, extending the box to you. You take one out, but it looks a little smaller than you remember. Well, they’re supposed to be stretchy.

You hurriedly take off your pants and underwear. Both of their breaths hitch. You unwrap the condom before attempting to roll it on. It’s uncomfortably tight, but it’s whatever, her safety comes first. Once you get closer to your base, it tears.

“Uh, shit, sorry, it’s been a while,” you apologize, noticing their wide-eyed stares.

“And I wear mediums,” Ellie reminds you. “Fuck, it’s been so long since I’ve seen it, I forgot you’d need a bigger size.”

“It’s okay,” Yukio says quickly.

“No, it’s not,” Ellie reminds her. “You may be on birth control, but it’s safer if we double up.”

“It’s safer right now for Y/N to be inside me. Look at her, she’s trying so hard, but it’s not gonna last forever. If you’re that worried about it, go get some in the right size while we…” Yukio trails off, a smile growing on her face. “Yeah.”

“Totally not gonna let that bruise my ego,” Ellie remarks. “Fine. Just- Be careful, you two, alright?”

“Always,” you breathe. You don’t know how much more of this you can take, Yukio’s propped wide open for the taking. You’re surprised Ellie isn’t already knot-deep in her right now. Her self-control is something you’ve always envied.

Ellie nods in understanding.

“C’mon,” Yukio encourages you. You join her on the bed. You want nothing more than to be decent, to cover her in kisses, to lick and nibble on her everywhere she’d let you, but… The muzzle. She sighs sympathetically. “Why don’t you lay down?”

Another growl from you makes her shiver, but you don’t smell any fear, only adoration and a touch of pity.

“What, you don’t like the idea of knotting my mouth while Ellie fills me up from the other side?” she teases. Oh, oh, that could be good. So good. A trickle of precum dribbles out of you as you smell Ellie’s arousal. Yukio giggles. “That’s what I thought, alpha. You can lay down or maybe even sit up a little right there,” she instructs, and you obey – some might consider it a little odd, but following the whims of your omega isn’t too much of a deviation from your natural instincts. “And Ellie can stand at the foot of the bed. I’ll be bent over it.”

Now that you’re all in your positions, you assess the situation. Ellie’s behind her, able to keep an eye on both of you. Yukio’s between you, already drooling a little at the sight of you. And you’re… Surprisingly okay, the scents of your mates seem to be soothing you into a more stable state.

While Ellie undresses, Yukio licks a stripe up your member and you cry out. It’s been so long. You can’t even bring yourself to masturbate, your shame and self-hatred making it hard to maintain an erection. This is different, though. Their acceptance makes living with yourself a little easier.

She continues to tease you with her tongue before taking you into her mouth. You can smell her wetness so strongly that if you close your eyes, you can almost believe you’re inside of it right now, which would be perfect if you weren’t having to dig your fingernails into your thighs to keep yourself from grabbing her ponytail and thrusting.

She pulls off of you, lifting her head with a smile.

“Good girl,” you sigh. “Is it too thick?”

She shakes her head.

“No, I just forgot to mention that I don’t have a gag reflex,” she chirps. “You’re so sweet, but you’re already holding back enough for me just wearing that.”

“And, uh, just let me know when it’s okay for me to start,” Ellie awkwardly adds.

“Go ahead, I’m… Just being here with you two is really calming me down,” you share, almost worried that saying it out loud will somehow reverse the effect they’re having on you. It’s never been like this before. Normally, another alpha being near your mate would make you angry enough to strongly consider murder as a viable option. Even the idea of Ellie being with her like this has stressed you out. Seeing it, though, being involved… It feels better. Not just better, but right.

You watch with bated breath as Ellie eases in. Her shoulders sag with relief, her hands wrap around Yukio’s hips like they were made to be there. And it’s okay. It feels good, even… Maybe because a part of you knows that if you told Ellie to pull out, she would, and she’d understand. She’s still subservient to you on some level, as your lover.

It’s then that you recall the evolutionary purpose of female alphas such as Ellie and yourself. You still have functional vaginas, so that if there were ever a shortage of omegas… You could breed. You pulse at the thought of being inside her, or her, you.

“Sweetie, you’re drawing blood!” Yukio yelps, pushing your hand away from your thigh.

“What’s wrong?” Ellie quickly asks. “I’m sorry, you were staring at me, but you didn’t look angry, so I thought we were doing good. Should I-?”

“No,” you snarl, cutting her off as she starts to back away from Yukio. “Stay right there. I just… We- My thoughts drifted.”

“Is this alright?” Yukio asks, just as concerned despite the need she’s surely having to ignore.

You nod fervently.

“I- You guys know I didn’t come here ‘til I was an adult, so I don’t know how comprehensive your sex ed was, but there’s something Ellie and I can do that not a lot of people like to talk about. I started thinking about it.”

“Oh,” Yukio squeaks, her eyes widening. “Oh,” she repeats, lower, with a grin. “I’d certainly like to see that.”

“I- I’m sorry,” you stammer, noticing Ellie’s apprehensive expression. “I’m sure you’d much rather be inside-”

“Wait, you want me to-? To-? You? That’s- That’s totally fine, I’ve just never had anyone or anything in me before. You’re pretty big, so I was more nervous about that, not that I’m against it or anything. I just know we’re having a lot of firsts here and I don’t want to take away attention from you or her.”

“I mean, you can smell it, can’t you? On both of us? We can all take turns being the center of attention. Speaking of, though, we’re not being very attentive to our dear omega. Is there more we need to talk about?”

“I think we’re good,” Ellie agrees, slowly moving her hips back and forth.

You tentatively hold on to Yukio’s ponytail while your other hand grasps the sheets. She bobs up and down your length, taking you both so perfectly. Her increasing moans match the increasing pace of Ellie’s thrusts. Your hips buck, and she groans hungrily, sucking harder. You decide to sync up with the two of them, and the three of you unravel in no time. Yukio takes deep breaths through her nose as your seed pumps down her throat. Ellie’s stays trapped in a condom, of course, but she’s locked inside of Yukio all the same. The latter reaches up underneath your shirt, massaging your breast.

“Trying to make it go faster?” you tease. “Don’t tell me she hasn’t been feeding you. Is this all you get to eat when you’re in heat?”

Yukio attempts to speak around you, but it’s no use.

“I make sure she eats, jerk,” Ellie huffs playfully. “She’s just taking advantage of the opportunity. You don’t really let either of us touch you, even when we’re making out.”

“I know,” you sigh. “I just- Ah!” Yukio starts moving her tongue. “I just- Fuck, worry so-ho much about ha-hurting you or going too far, fuck, Yukio, you’re… Perfect, don’t stop, please.”

“I didn’t realize how much she’d like this, every time you moan she squeezes around me,” Ellie informs you, looking a bit winded herself.

Yukio gently scrapes her teeth against you and you lose it all over again, including your balance this time. Ellie chuckles, before slipping out of Yukio and stepping over to you. She takes the muzzle off.

“El-”

“Someone’s gotta clean this up, and Yukio’s mouth is a little occupied. Wanna help me out?”

It’s a flimsy excuse – once the condom is off, there won’t be a hint of Yukio on her. She slides her finger against her length before sliding it against your tongue. It tastes like honeysuckle nectar. She pulls the condom off, offering herself to you. If it was literally anyone else’s, you’d bite it off.

“Never done this before,” you remind her as you prop yourself back up. “Might not be any good.”

“It’s you. That makes it good.”

You’re burning up, so you finally take off your shirt. She bites her lip before she lines herself up with your mouth as best as she can. It’s a little sideways, but at least that prevents it from going too far in too soon. You carefully take her into your mouth. She gives a pleasured sigh in response, stroking your hair and brushing it out of your face.

“That’s it. You like that?” she murmurs.

“Mhm,” you hum. She shudders, her hand tightening in your hair. You feel Yukio’s mouth leave you, but not longer after, you’re inside her once more. You find yourself clinging to Ellie as waves of pressure roll through you. You swallow around her and she chokes on air, holding onto you for dear life.

“Hol-y fu-cking sh- I’m- That’s so…” Yukio moans, bouncing on you harder.

“That’s it, baby, touch yourself,” Ellie encourages her, before pulling out of your mouth.

“Did I-?”

“No, any more of that and I was gonna knot your mouth. Figured you wouldn’t be a fan of that. Besides, your omega needs you,” she clarifies.

You turn to Yukio, who’s furiously stroking her clit with her eyes forced open and her mouth agape.

“God, that was so fucking hot,” she whines. “My alphas, so good to each other, so good to me.”

“All for you,” you groan, she’s practically milking you with how tightly her insides embrace you. “Close your eyes, baby, focus on your own-”

She shakes her head.

“I don’t wanna miss a thing. Needed you like this for so long,” she insists. She smells so good, like petrichor – a euphorically relaxing rainy day wafting through the air. She feels like- Like her, so beautiful and perfect.

You flip her onto her back and start drilling into her in the blink of an eye, one hand tangled in the hair at the base of her head and the other gripping her hip as you force her to meet your thrusts sooner and sooner. You keep your mouth shut, focusing on that just as much as your other actions. “Oh, fuck, I- Holy fu- Ah, so hard, never- Sorry, fuck, I’m gonna-” her whole body tenses up, a high-pitched noise squeaking out of her like a muted scream.

“Way to show me how it’s done,” Ellie remarks before giving you a playful smack on the ass. “Didn’t realize you liked it like that, Yukio.”

“Not sure I knew that either,” Yukio pants. “Holy… Wow.”

You beam with pride at your omega’s approval, jaw still clenched as tightly as you can manage. She reaches up, massaging it.

“So good to me,” she repeats, her hand drifting to the curve between your neck and your shoulder. You’re ashamed as she feels the layers of scarring. Eventually, they’ll fade - they already have significantly, some are no more than marks on your skin. “All mine. I know it’d be hypocritical of me, but-”

“Yes,” you know what she’s asking and you answer without hesitation, leaning even closer to her.

“Oh, Y/N, I don’t… I don’t want to take advantage of you like they did. Let’s wait until my heat’s over and do it then. Tomorrow, okay?”

Of course. It’s not a true rejection, but it hurts like one nonetheless.

“I think I know of a way we can prove that she really wants it,” Ellie says, trailing a hand up your back. “Would you want me to bite you, too?”

You nod fervently.

“At the same time,” you add. “One on each side.”

“Okay,” Yukio agrees. Ellie gets behind you, leaning forward on your back and wrapping her arms around you. She smells amazing, too, like the sweet smoke of a campfire.

That’s when it hits you. It’s not that she’s subservient to you – all of your alpha instincts are in overdrive. You want to be subservient to her. When you had her in your mouth, you wanted her like Yukio wasn’t even there, but she was, so it was even better. This is the only kind of relationship that can satisfy all of your urges, isn’t it?

Why didn’t you ever feel like this before? You’ve never had the urge to mate with another alpha… Then again, Ellie’s unique – she has the doe eyes, round cheeks, and petite physique more commonly associated with omegas, the balanced approach of a beta, and the strength and confidence of an alpha. She’s as perfect as Yukio, just in a different way.

“You’re shaking,” she murmurs.

“It’s you,” you whisper, scared to admit it. “I- I can’t explain it.”

“Do we need to stop?” she asks, clearly alarmed by your vague declaration.

“No, I mean… My- I-”

“It’s what she said earlier, about you two doing what alphas do when there’s a shortage of omegas,” Yukio realizes. “With your mutation, you feel it anyways, don’t you? You need her.”

“I- I do, but it’s not like I don’t recognize that you’re here. I love you, and I’m so glad you are. It’s like it’s… Coexisting, even if it’s contradictory.”

Ellie hugs you tighter.

“Then we better get to it, alpha,” she whispers before pressing kisses to your neck and finding her place. “Right there?”

“Oh, god, yes,” you find yourself begging. “Please.”

Yukio takes the spot you offered to her, and they both sink their teeth in. You gasp in pleasurable pain, hips twitching forward as Yukio flutters around you.

They guide you out of her and onto your back.

“Wow,” Yukio says softly. They can feel you better now – your needs, your worries, everything.

“Jeez, your knot’s still pretty full. Wait, Y/N, do you not…?” Ellie trails off, digging in the box for a new condom and rolling it on as quickly as possible.

“What?” Yukio asks. “I just thought it was bigger, since, y’know…”

“There’s no way you can call her dick bigger than mine nicely. It’s a fact. It’s fine,” Ellie huffs. “Anyways, no, proportionally, it still hasn’t deflated as much as it should be if she’s emptying it regularly. Why haven’t you been?”

“I- I just can’t,” you confess. “I try, but… Please, don’t- I can’t-” If you cry right now, you might actually die of embarrassment. “I hate it so much sometimes, the way I feel.”

“Baby,” Yukio coos.

“Don’t- You’re in heat, Yukio, I should be fawning over you, not-”

“We’re mates, Y/N,” she argues. “And since I go into heat regularly, it winds down a lot faster. It’s easier to keep a clear head. As your omega, I’m asking you to let us take care of you right now.”

“And as your alpha, I’m demanding it,” Ellie insists, her eyes burning into you. You relent, avoiding them and nodding.

“That’s it,” Yukio hums. “Relax. It’ll hurt if you don’t.”

Ellie circles to the end of the bed while Yukio remains by your side. The former carefully pushes a finger inside you once the latter starts stroking your member. Oh, wow, that feels so- She curls the finger inside of you and you jolt. Both gasp.

“Well, if you’re that sensitive, we’ll have this worked out in no time,” Ellie remarks. “You think you can take another finger?”

“Yes,” you agree breathlessly. She pulls her finger out of you, adding another. Your eyes shut tightly, sight is a sense that’s no longer necessary – in fact, it’s too much. “Ah, that’s… Oh.”

“Good?” Ellie offers, chuckling. You nod, your teeth worrying your bottom lip. It’s almost too good. Yukio’s hand tightens around you as she increases her pace.

“F-f-f…”

Ellie inserts another finger, preparing you for what’s to come. Is this how omegas feel? It’s spectacular, being so full of someone you love and need so much, knowing they feel the same way. You know you have to treat Ellie to this one day.

“Ready?” she asks, clearly just as excited about this development.

“Yeah,” you confirm. She pushes inside you and the dull pain of the pressure is nothing in comparison to the ecstasy of feeling her inside you. Yukio’s hand slows to a stop. “Move, you can move.”

“Goodness…” Yukio mumbles, like something’s in her mouth. You open your eyes to find one of Ellie’s fingers there. Ellie pulls away, cleaning the other two.

“It’s like… Peaches, or nectarines…” Ellie murmurs. “Right?”

Yukio nods.

“So good,” Ellie groans, her hips finally rocking. You can feel every inch of her. It’s bliss. The only thing that compares to this is being inside Yukio, whose smile widens as she feels your thoughts drift to her. She starts stroking you again. If what was happening before was bliss, this is indescribable.

You can’t help the moans and whines being ripped from you as your eyes roll back. They’re downright pathetic, but they seem to fuel both women.

“Yukio, I want- You’re not gonna feel left out if I…?”

“No, have your moment. I should be touching myself anyways, to get the rest of it out of my system. I get the feeling I won’t last long… My two alphas, gorgeous. I’m so lucky.”

Yukio’s hand leaves you as she leaves the bed, opting for the chair at your shared desk. You whimper, but her hand is quickly replaced by Ellie’s as she adjusts her position, hovering over you.

“Can I go faster?” she pants.

“Yeah,” you confirm.

“Look at me,” she demands. You open your eyes to meet hers. There’s so much love in them. “My alpha,” she breathes. “So strong, taking me so well.”

“My alpha,” you echo. “Feels so good, don’t- Oh, don’t know how I lived without it.”

“I don’t know how I lived without this, either. All of this,” she replies. “How could I even breathe in this room without you here?”

She snarls, angry at her past self’s negligence, before she starts absolutely pounding you. You’re seeing stars in the best way, your hips still lifting to meet her thrusts as she jerks you off. Your hands, paralyzed by surprise, now find themselves clawing at her back hungrily. You get the urge again and redirect your focus to clenching your jaw shut.

Ellie notices quickly, now bearing down on her elbow to bare herself to you.

“Do it,” she says.

“But-”

“Do it,” her alpha voice comes out. Its effect ripples through you like nothing you’ve ever felt before: you feel protected, loved, euphoric, but it’s on a completely different level. You pull her impossibly closer, getting a mouthful of her and biting down hard as your pleasure peaks. It’s a good thing you did it, too. The sounds you’re making right now would likely alarm someone unaware of the situation and the last thing you need right now is for someone to bust down that door and rescue you from this.

You pull away to catch your breath.

“Good alpha,” she sighs, removing her hand from your member to caress your face. She slows down, but it’s clear she’s not done yet. Evidence of your orgasm is splattered across your chest and hers. She trails a finger up yours, grazing your nipple teasingly. You spasm, and she smirks, tasting you.

“Can I just say…? That was super fucking hot,” Yukio comments, clearly pleasantly bemused.

“Come here,” you tell her. “I wanna taste you.”

“Oh, uh, our other alpha might not take too kindly to that. Looks like she’s enjoying having both of us as her willing slaves.”

“Please, Ellie,” you beg. “I want both of you inside me.”

“How can I say no to that?” she lifts her head to look at Yukio as she replies before cutting her eyes back over to you. “And how could I deny her your mouth when I know how good it feels?”

Yukio rejoins you on the bed, mounting your face. You explore her folds with your tongue as both girls rock their hips. There’s no word that better describes all this than perfect. Yours, Yukio’s, and Ellie’s moans fill the room as much as your scents do, swirling together in a blend that was meant to be.

You find yourself clawing at Yukio’s back now. It’s just enough to satisfy your urge to mark her, and she knows it, praising you between whines and whimpers.

Ellie finishes once more, and you follow. Yukio’s last, Ellie holds her up and keeps her from falling as she quakes.

“I think… I think that was it,” Yukio pants. “I’m good. You two?”

Ellie nods, as do you.

“Time for a cuddle pile, then!” she cheers. Each of them nestle in your side as yours and Ellie’s members retract.

“That was…” you take a much-needed breath. “Perfect.”

“Agreed,” Ellie replies.

“I’m sorry you were excluded for so long. I know it was mostly your idea, but we should’ve fought for you,” Yukio says.

“It’s okay. I just hope I can figure out why my medicine stopped working,” you reply. “I mean, I can go off of whatever suppressant I end up trying next for your heats, if you want, but it completely stopped working.”

“Oh my god,” Ellie blurts in realization. “You just got that refill yesterday, didn’t you?”

“Yeah, how’d you-?”

“I keep track,” she cuts you off. “They’re placebos, Y/N. Your medicine still works.”

You sigh in relief.

“I’ll give them a call later and see what can be done,” you decide. “For now, as Yukio said: cuddle pile.”
