Chapter Text
Shit! Shit, shit, shit! Of course this would happen to Will right now. This couldn’t happen literally any other time?
It’s winter break for college and the party decided to go back to Hawkins for the holidays. It’s the week before Christmas now and Will is going into a pre-heat. Because of-fucking-course he is! He thought he felt a bit off leaving campus with Jonathan, but he thought it was just a cold coming in mixed with anxiety at seeing everyone again.
Now, sitting in the bathroom in the basement of the Wheeler’s home, Will feels like an idiot for not noticing. He’s cramping and way too warm. With a small whine of discomfort, he takes off his sweater, leaving him in only his white undershirt. He wraps his arms around his middle and sits down on the floor. Someone is bound to come looking for him soon. It would be so embarrassing for the young Byers if his friends found him like this.
The only alphas are Lucas and Mike, they would know what it was right away. El and Dustin are betas and would be none the wiser to what’s going on unless Will was actively leaking slick in front of them. That thought makes him cringe in disgust. He needs to get out of here before someone comes down for him.
He starts to try and think of excuses but nothing is coming forward in his heat-hazed brain. He could text his mom? She would come right away, but maybe make a scene and tell the other parents why she’s suddenly here. Jonathan would be discreet, using the guise of seeing Nancy and sneaking Will out. But then Nancy would know and she would tell Mike the second he asked where his friend went. Ugh!
“Will?” A painfully familiar voice calls. Speak of the devil and he shall appear.
“In here!” Will responds, sounding pathetic even to his own ears.
He hears Mike come right to the bathroom door. He starts to tremble as his friend’s scent surrounds him. Mike’s always smelled the best out of the rest of the party. Like fresh rain and forest greenery, it’s so comforting and reminds Will of when they were kids playing in the woods. Mike says Will smells like coffee and marshmallows, strong yet sweet.
Mike must be using his pheromones to produce a calming effect since Will’s shoulders drop and his worries subside just a bit.
“Will, are you okay? You smell…” he trails off, not wanting to make his friend feel worse. Will appreciates the gesture.
“I need to get home. Jonathan can get here in fifteen minutes, it’s no big deal,” Will says, his voice meek with embarrassment.
He swears he smells Mike’s scent sour slightly, but it’s gone as soon as it’s there.
“Are you sure? I could drive you home, it’s no problem, Will.”
Always so sweet and so worried. Will’s heart tugs strangely. Mike’s always been there for him, ready with a calm voice and steady hand whenever Will needs it. But does he trust himself to be alone for the car ride? What if he gets spurred into a full heat by the time they get to the Byers’ house and he embarrasses himself by begging for Mike to come inside with him?
“No, it’s fine. Honestly.” Will decides, shaking his head despite Mike not being able to see it.
He hears Mike sigh, he probably rolls his eyes too while he’s at it. “Come on, Will. It’s fine, we all have been in a similar situation at some point. It makes more sense for me to take you back home anyways.”
Maybe he’s right. Will can’t even think straight. The cramps are getting worse, his skin heating up well past warm at this point. He needs to go before he starts to stink up the Wheeler’s bathroom with his heat stench. They would probably not appreciate that and Will would not be able to show his face in this house for a year from humiliation.
He doesn’t answer, instead he struggles to his feet and opens the door. Standing there looking so devastatingly handsome is Mike. For some reason he looks even better right now in the dim light of the basement than he ever has. Will clears his throat and motions with one hand.
“Okay, take me home then,” he mumbles, his face heating up with blush.
Mike is looking at him funny. Not in an insulting way or even shock. He’s just staring. Briefly, his eyes flicker down to Will’s lips and then back up to his eyes, his eyes dilating slightly. Hormones, Will’s brain supplies unhelpfully. He’s an omega and Mike is an alpha, this sort of thing is normal. Lucas has been affected by Will’s pre-heat in the past when they were in high school. It means nothing that Mike is looking at him like this right now.
Suddenly, Mike clears his throat and turns quickly for the stairs. Will follows at a slower pace. Wordlessly, they both make it upstairs and to the front door without anyone saying anything. Nancy gives them a look from the couch, but Mike makes a show of grabbing his keys from the front entrance table and she nods in understanding.
Will’s blush does not budge from his face. He purposely avoids looking up as he leaves the house, not wanting to accidentally see Mike staring at him again. It would give his stupid omega brain ideas and he does not need to fantasize right now.
Mike leads him to his car, a hand-me-down from his dad when he got accepted into college. Hawkins was always so convenient that the party still biked everywhere and bummed rides from Jonathan or Steve whenever they needed to go anywhere further. Mike holds the door of the passenger seat open, Will thanks him quietly before slipping in.
Everything in the damn car smells like Mike, it's absolutely maddening.
As Mike rounds the front of the car to get in, Will allows himself to whine once. The sound had been caught in his throat from the moment he saw Mike’s eyes look as black as they did. He cuts himself off when Mike gets in, forcing himself to look at his lap instead. He’s aware of Mike starting the car and lowering the radio. It’s freezing so he turns the heat on and sits back to let the car do its thing.
“Feeling okay?” Mike asks, voice soft and quiet over the hum of the car’s engine. He’s staring again.
Will nods, afraid that if he speaks he’ll start whimpering and whining for the alpha’s attention. Now is the worst time for his brain to remind him of all the times he spent crying out for Mike during his heats since he first presented. Why couldn’t he have been firm on wanting Jonathan to come pick him up?
Mike puts the car in drive after a few minutes and they begin their journey to the Byers house. Will tries to think of other things to distract his mind from his body’s betrayal. He’ll have to hoard nonperishables and water in his room until this is over. Luckily his suppressants and birth control make his heat only last a total of three days instead of a week like normal, unmedicated omegas. He’s in the middle of thinking about what granola bars he wants to take from the cabinets when the first rush of slick leaks out.
“No!” Will groans in horror, pressing his thighs together to no avail. It only makes a spark run up his spine at the unintended friction.
“What happened?” Mike asks, shocked until he sniffs the air and gets his answer. He splutters, apologizing immediately.
Will covers his face with both hands, curling in on himself in an attempt to be smaller. He wishes he could melt into the leather seat below him and fade away entirely. Mike covers his nose and mouth with one hand and steers the car with the other. At this point, they are almost to the Byers house.
Heat licks up Will’s spine, twisting his insides as the pain becomes its worst. He feels sweat gather on his brow and upper lip. Between his legs, his cunt pulses with want. And of course Mike smells so fucking good like always. This is like a nightmare and his best daydream all at once in one twisted package.
“Don’t worry, we’re almost there,” Mike says encouragingly, breaking the tense silence.
Will nods but he isn’t really listening. Everything feels so horrible, he needs to get inside the house and lock himself away right this instant. Thank goodness he brought his supplies with him before he left his dorm for the break. He tries to think about his toys in his bedroom instead of thinking of Mike. Unfortunately, the thoughts of his knotting dildos turns into how big Mike’s knot would be inside his pussy. Will whines high in his throat without even realizing it.
Mike answers with a barely concealed growl. He must not have been able to help it, it must have just been the biology of the situation. Will must be releasing all kinds of pheromones right now because Mike smells heavier than usual. His scent coats the inside of Will’s mouth, flooding his senses and demanding his attention. He wants nothing more than to beg for Mike’s help right at this moment.
“Almost there,” Mike says again, this time sounding like he’s talking to only himself.
Will groans, pressing his thighs together tighter as a fresh wave of slick rushes forth. He’s so fucking wet he’ll probably leave a goddamn puddle when he gets out. Maybe Mike won’t offer to walk him to the door and he can just stumble inside before he says anything embarrassing? The very thought of being without Mike right now sends a pain through his chest. He needs the alpha beside him like he needs air in this very moment, it’s almost too pathetic for Will to take.
He realizes awkwardly too late that they’ve pulled into the driveway. Mike gets out, rushing around to open Will’s door. “Come on, let’s get you inside,” he insists in a quiet but tense voice.
He looks highstrung, all tense like he’s about to snap. Will almost wilts at the thought of the alpha not liking the way he smells or not wanting to be near him. He’s just being nice, Will thinks, making sure he gets inside okay like a good friend.
Will must be crying because Mike leans down to be in his space and swipes his thumb across his cheek.
“Come on,” Mike whispers more gently this time. His eyes are dark but shining with affection for the omega.
Will nods, getting out of the car then. Mike is there to wrap an arm around him for support. He shuts the door behind him and walks them both to the house. He doesn’t say anything and neither does Will as he opens the unlocked front door and takes the younger inside.
“You go to your room, I’ll grab some stuff in the kitchen,” Mike suggests but it sounds more like an order.
Will feels himself ache for him. Alpha’s taking care of him - his brain cheers unhelpfully. Awkwardly, Will stumbles to his room and nearly collapses onto his bed. Everything feels sluggish and slow but burning hot at the same time. He strips off his shirt that’s slightly damp from sweat by now. It’s not enough. Wiggling out of his jeans is difficult, but he managed to do this after a minute. He’s laying down in just his underwear on the bed panting through the growing heat when Mike comes back from the kitchen.
“W-will?” Mike’s voice calls from the doorway. Will cracks an eye open to look at him and sees the older standing there, lips parted and breathing heavy.
Will flushes and feels himself clench around nothing. Mike is staring, staring at him! Mike moves towards him, still looking at him like he’s the most transfixing creature in the world. The things in his hands fall to the floor and he makes it to the edge of the bed where Will’s legs dangle off the side.
“Will?” Mike is whispering this time, his eyes finally meeting the younger’s.
A keening sound claws out of Will’s throat, and the next thing he realizes Mike is leaning over him on the bed. He’s too close but at the same time not close enough. Distantly, Will realizes he’s being scented. Mike is sniffing at his collarbone and pressing his face into his shoulder.
“Mike!” The younger male gasps breathlessly. He forces himself to keep still, hands fisting the comforter below him so he doesn’t grab Mike and force him to kiss him.
“You smell so good,” Mike mumbles, still nosing at Will’s sweat-slicked skin.
If he wasn’t wet before from heat, Will would be soaked by now. He relishes in having Mike’s attention like this, but he needs to get out of this situation before they both do something they might regret.
“You should go, I-“
“Please, Will, I promise it’ll be good~” Mike pleads, voice sounding desperate now.
Will’s brain blanks out. Did an alpha - Mike - just beg to let him… what? Mike doesn’t wait to hear Will’s response, he continues to scent him and even has started pressing light kisses to his scent glands.
“Will?” Mike prompts, sounding hopeful. “Please, baby, let me stay with you?”
“What is happening?” Will mumbles to himself. He must be a criminal now because his traitorous brain sings at the attention and desperation of an alpha - especially the one he’s been chasing after for years.
Mike’s hands are on him then, trailing up his sides and back down again to grip his hips. Finally, throwing caution to the wind, Will allows his hands to tangle in Mike’s curly black hair to pull him up face to face. He looks so drunk, his dark eyes blown wide and his pale skin dyed with blush. Mike surges forward, sealing their lips together and pushing the younger into the bed with the force of it.
He wastes no time in licking hotly into Will’s mouth, massaging his tongue with his own. They swallow each other’s sounds, almost like they are trying to keep the other quiet. Will thinks about his mom and Jonathan who are probably asleep in their own rooms.
Will pushes on Mike’s chest then, urging him to stop. When they part, he feels like he can’t catch his breath for a moment. “We can’t do this,” Will pants.
“Why?” Mike demands, looking genuinely confused and a bit upset. “I can be good for you, please.” Somewhere in his mind, Will knows this is the alpha part of his brain talking. Mike wants him because he’s an alpha and Will’s an omega, it’s simple biology. But goddamn does he want him so bad right now.
Will nods, the words caught in his throat and mixing with a borderline animalistic whine. Mike takes that as a yes and goes back to pushing his face into his scent gland. He presses hot, open-mouthed kisses to the heated, swollen skin. Will moans at the simple touch, his back arching. Mike’s big hands are on his hips, pressing him down into the mattress. He licks and sucks at his neck, his teeth grazing lightly at the promise of bonding. He can’t, Will knows this.
“M-Mike, alpha! Please, need you!” He groans, trying to distract him from biting. Even though he would love nothing more than to be bonded to the alpha above him, he knows it wouldn’t be right without both their consent on the matter. They’re both too horny right now to think straight.
Mike obeys instantly. He hooks his fingers into the waistband of Will’s underwear and pulls them off, shucking them somewhere in the room with the rest of his clothes. Above him, Mike moans at the sight before him.
“God, look at you, so pretty,” he praises. “So wet, all for me?”
Will nods feverishly, feeling himself clench around nothing. He sobs, his cunt feels so empty and he can barely take it. His rational mind is slipping, making way for the more baser part of his instincts. Shakily, he spreads his legs further and reaches one hand down to trail over his heated skin. Mike watches, transfixed. Will keeps his eyes on the alpha’s as he teases his index and middle finger over the outside of his cunt. Feeling braver, he uses those two fingers to enter his aching hole and lazily pump in and out.
“Fuckin’ christ!” Mike curses, panting so heavy at just the sight. “P-please, let me do that?”
Will smiles, feeling fuzzy and feverish. With his other hand, he grips Mike’s shoulder and brings him closer. They kiss but it’s more uncoordinated than before. Mike knocks Will’s hand away from his pussy and replaces it with his own. He wastes no time in filling his hole with two fingers. Will screams with pleasure at the intrusion, his upper body nearly rising completely off the mattress. Mike ravishes him, fucking his fingers in and out while stroking his clit with the pad of his thumb. It’s too much and not enough at the same time.
A tight feeling begins in Will’s lower belly, a pooling heat accompanying it. He’s going to cum, and fast. A sob rips from his throat and Mike growls low in answer. Mike seals his lips with his own, pressing hard and licking uncoordinated into his mouth. Will tenses, his walls fluttering around the alpha’s long fingers. He feels so full of Mike already, it’s intoxicating.
With a few final thrusts, he’s cumming all over Mike’s hands. He feels more slick pour out of him, his walls spasming and a loud broken moan spilling from his lips. Will’s back arches from the bed, his body tensing as his orgasm rips through him. Mike is talking, whispering praise into his ear as he fucks him through it. He crooks his fingers up, touching that spot inside Will that makes him cry out again. He whimpers from overstimulation, his whole body feeling on fire still.
“That’s it, baby, doesn’t that feel good?” Mike practically cooes in his ear. His other hand comes up off Will’s hip then to touch his neck where his mating gland is.
Will groans, his hips stuttering from aftershocks. “Alpha~” he slurs, “wan’ your kn-knot.”
Mike curses low under his breath. “Fuck, baby, really?” He asks, his tone hopeful.
Will nods quickly, keening high in his throat. Mike reaches for his own cock, slicking himself up with Will’s slick and cum. The omega groans at the filthy, wet, sound produced. He feels Mike’s cock press at his entrance, pushing in with one brutal thrust. Will practically wails at the new feeling. Mike grinds his hips forward, allowing Will to adjust. And he feels so full, so fucking full.
“Alpha!~” Will whines, rolling his hips as a signal to move. And, fuck, does he.
Mike uses both hands to hold Will’s thighs open, gripping tight as he pulls his hips back and pushes back in in a punishing thrust. He groans as Will cries, their sounds mixing together along with the sounds of their skin connecting. He’s so fucking wet, and Mike is pushing in as far as he can go with every thrust.
“God, you’re practically sucking me in, baby,” Mike hisses, grinding his hips forward just to watch Will’s face more closely.
He looks a mess himself, but Will knows he’s in a worse state. They’re both sweaty, red, and their scents are mingling together so perfectly. Citrus, woods, blueberries, and moss all dancing in the air around them with sex.
Will doesn’t know if he can respond intelligently anymore. He whimpers, gasping and and letting out little “ah, ah, ah’s” every time Mike fucks back into him. Their bodies rock against each other, Will does his best to try and grind his hips, but he’s uncoordinated and feels all messy inside his head.
One of Mike’s hands moves from Will’s thigh and instead settles on his lower belly, pushing just slightly and it immediately feels like heaven. Will sobs, tears staining his blushing cheeks.
“R-right there!” He begs, moving his hips more frantically to match Mike’s thrusts. “Alpha!”
Mike hushes him sweetly, reaching to toy with Will’s clit. He rubs his finger around it first, circling towards the center and pinching the jutting bud. Will feels like he could pass out, his eyes rolling back in his head from the pleasure. A new wave of slick gushes from his cunt and Mike growls possessively.
“I can’t believe you’re all mine,” Mike says, out of breath. “It feels like your cunt was made for me, omega~”
Will preens, smile watery as he nods. If only Mike understood just how much this is all so perfect. No doubt the hormones are doing something to him, omegas in heat are almost undeniable to any alpha that is unclaimed or unrelated.
Mike leans down, kissing Will’s jaw before kissing him on the lips again. It’s a sweet kiss, and Will sobs into it. Between them, there’s no doubt Mike is getting close. His thrusts are becoming sloppy and his knot is slowly inflating at the base of his cock. Will groans, feeling the knot push against his clit with every new thrust. Mike obliges him, making his thrusts more rough and slow to grind them together. He’s so perfect, so attentive to Will it makes him physically hurt.
“Wan’ cum, wanna cum!” Will begs. His arms come up to wrap around Mike’s neck, pulling him down for another kiss.
Mike smiles against his lips. “Ok, baby, ok.” He goes to pull out and Will wails. He’s shushed immediately and soothed with another kiss. “Baby, I can’t cum in you. You’ll get pregnant, let me lick that pussy of yours to make it better?”
Will shakes his head, feeling like he’s about to throw a tantrum like a spoiled child. “Please! Please, alpha, need it!” He cries. “Wan’ your pups, please!”
Inwardly, he knows they can’t do that. He can’t jeopardize their lives this way when they’re still in college. But, his insides scream for it. He feels so empty and Mike feels so right inside him. He wants this forever, no matter the consequence.
“Baby~” Mike soothes, reaching his hand to pet Will’s hair. He glides his hand down to graze over the omega’s mating gland, causing him to shiver. “God, you can’t say things like that. I wanna give them to you, I do, wanna fill you up. You’ll be so pretty, all heavy with my puppies. God!” He is not helping this argument.
Mike’s hips stutter and he presses in with a curse, seemingly forgetting about his previous no. His knot pops right into Will’s hole and he screams, cumming at the same time he feels Mike’s cum begin to fill him. Alphas cum so much, it floods inside and presses into Will’s cervix. He moans, head lolling back at the feeling of being so goddamn full. He pulls Mike down to press his face into his scent gland, not biting but just breathing in greedy lungfulls as he’s bred by the alpha.
Above him, Mike is still babbling on. “You’re so perfect, gonna let me breed you all the time. Keep you full. I’ll be so good to you, baby, promise!” He’s practically whining. He grinds and gives little thrusts as he tries to pump more into Will.
Will smiles, wrapping his arms as much as he can around Mike and just listens to him talk and say random things until he’s finished cumming. Once he is, Mike gathers him up and pushes them both higher onto his bed to lay down. Still locked in place, he rests his head on Will’s chest and wraps his arms around his waist. Will cries silently, the simmering warmth of his heat now becoming background noise. In a couple hours he’ll need attention again, and maybe Mike will be there when it comes back, maybe he won’t. Eventually, Will closes his eyes and accepts sleep, thinking about the alpha wrapped around him.
