Work Text:
Dustin leaned over Steve's back to look at his textbook, humming as he read over the fairly simple equations Steve was suffering through. He adjusted his position, from the hand he had on Steve's shoulder, dragging it slightly to the right, until his palm rested on Steve's nape. Dustin asked which problem was causing Steve the most issues, to figure out which formula they needed to work on the most, but the entire time he ignored how Steve froze up as he applied constant gentle pressure to the scent spots on either side of Steve's mating gland.
"So, okay, you said the issue was more with questions in the later half of the quiz?" Dustin asked, leaning in a bit closer, rubbing his shoulder into Steve's. "I think maybe your grades in Trig weren't the best, huh Prom King?"
Steve stumbled through a response, face turning slightly pink. One could have mistaken it just as him being embarrassed; after all, since coming to college, he needed the help of his 5 years his junior friend to tutor him through his classes. Plenty of people were surprised that they knew each other, let alone were close. Dustin tried to not give him too a hard time on that front, Steve might not be school smart, but he was trying and Dustin had been ecstatic to find out Steve was coming to his school.
And, Dustin knew it wasn't just embarrassment Steve was feeling right now. Eventually, Dustin moved his hand from Steve's neck, as he took a seat next beside him at the library table. Their legs touched below the table, but at this point, Steve was fairly used to Dustin's scent being all over him. That hadn't always been true, but Dustin had worked on that first. Just as Steve took a breath, relaxing, squaring his shoulders, Dustin grabbed his wrist. He took his hand into his, guiding his pencil to the paper.
"Right here, this is where you're getting things mixed up. I can see what you were thinking, but you're going to struggle the entire class unless we get you back to speed on basic algebra and trig. I'm sure it'll come back to you, plus I'm a great teacher." Dustin told him, but as he spoke, his thumb brushed against the scent gland on the inside of Steve's wrist. It was a bit swollen, Dustin figured he was getting close to a heat, though he'd never tell Dustin that.
That was sort of the issue, and how all of this started.
Dustin never believed Steve was an alpha, no one ever said he was an alpha. Even when Dustin was young, with no connection to the guy besides a vague memory of him as a sixth grader in the brief span of time they were in elementary school together. Steve had no alpha features; no slit pupils, his scent glands weren't in the right spots, and while it wasn't visible, Dustin knew Steve had enough dating experience now that he assumed someone would have mentioned his knot if he had one. No, Dustin believed Steve was a beta, a cool one, but a beta all the same. Same as Lucas, Jonathan, and Max. Pretty much all of Hawkins believed the same, it wasn't until Dustin was 17 that realization clicked into place.
He'd gone over to Steve's apartment, after his friend had declined to do a movie night, saying he wasn't feeling great. Dustin, wanting to make up for being a bit of a bitch the year before, thought he'd take Steve some homemade soup. Instead, he was met with Steve's mother, a beta, in the doorway, looking apologetic. She'd only started coming around recently, and while Steve didn't talk about it much, he was clearly happy to be reconnecting with at least one of his parents. She wasn't very bright, a former cheerleader turned secretary, but she was nice enough.
"Oh, Henderson, right? I'm sorry, he's really in no shape to be near you, not right now. Thank you so much for coming to check, though." The older woman said, a small frown on her face as she stood in the doorway, moths flitting about the light beside it. "You know, he's always hated being around alphas, but...I think you're good for him. I can tell you care, not like some of his other friends..."
Dustin didn't think she meant Robin or Nancy, moreso the clique Steve hung out with in high school, Tommy Hagan and Carol what's her face. He'd never heard that Steve disliked alphas though, he'd always been very respectful towards Hopper and El, and he'd never treated Dustin any different.
Steve's mother, Sally or Susan or something, reached over, and pinched Dustin's cheek affectionately, and he had to fight the urge to slap her hand away. "You're a sweet boy, I can tell. You're a bit young now, but... in a few years...I think you'll be good for him."
Dustin had left, soupless and confused, she'd taken that, and left him with just a million possible questions. Disappointed he'd not been able to see Steve, Dustin flopped down into bed, wondering what the hell all of that had been about. For awhile, he'd simply laid there, Tews eventually curling up on his chest, purring away.
It had hit like thunder, a crack that had Dustin sitting up in bed, rolling Tews off onto his lap in an undignified manner.
On the phone when Steve had cancelled, Dustin had given him shit because it seemed like Steve got sick every couple months, ruining their plans. Steve was always mildly apologetic, but usually blamed getting sick on always being around snot nose kids. Dustin didn't think about it, not at the time, but now? It wasnt every couple months; no - it was every three months, almost on the dot. Almost like it was scheduled; like someone on blockers might have scheduled their heats. Then, everything else seemed to make sense.
"Mother fucker, he's an omega." Dustin said with wonder, outloud to only himself, his tortoise, and Tews. "Goddamnit, Steve."
Then, something like anger began to bubble up inside him. After everything they'd been through, the sheer amount of times they'd nearly died together, and Steve never bothered to tell him that? Why not? He knew Dustin didn't care, Will and Mike were omegas, and they were Dustin's friends. It wasn't a big deal.
Unless Steve cared.
That bugged Dustin, far more than it should.
He wanted Steve to tell him, but something told him Steve never would. Steve had always been pretty private about himself, which annoyed him to no end.
So, Dustin turned to science; or, rather, biology.
Most aspects of secondary gender was just left over evolutionary bullshit, in his opinion. Sure, alphas had slightly different eyes, making it easier to see at night, and the theory was it made it possible to find omegas in the dark and hunt, which would have been good a few thousand years ago, but that wasn't useful in the modern age. All it meant was Dustin could ride his bike home at night and see just fine. Not needed, barely beneficial. That's how he'd viewed most of it, just unnecessary organs, like his tonsils. At least, until now.
After that little realization, Dustin began to do research in the library. What were things so specific, so unique to omegas, that Dustin could use against Steve. Not in a cruel way, of course, and he wasn't a creep, it wasn't to mate him or something, Steve would never think about him like that - it was just enough for Steve to hopefully say, 'you can't do that anymore', and come clean. He didn't want to hurt Steve, and didn't want to piss him off to the point that Steve avoided him.
But, a little push towards the truth couldn't be bad, right?
Dustin knew it had to be a slow process, glacially so, otherwise Steve would catch on. He wasn't the brightest bulb out there, but Dustin knew Steve wasn't as dumb as some people acted. Plus, he knew Dustin so well at this point, if he acted too suspicious, Steve would clock it fast.
The next time Steve was "sick", Dustin had made sure to "accidentally" leave his sweater in Steve's room a day or so before. It wasn't a lot to start with, but it meant his scent would be familiar and nearby to Steve during his probable heat. It all started small, like that, and Dustin didn't even begin touching scent glands on him for maybe a whole year. Up until then, he just worked on scenting him, brushing against him, borrowing his jackets, laying in Steve's bed when they were hanging out. Everything to tell the little monkey brain that controlled their secondary hormones that Dustin was a friend, a good alpha. A trustworthy alpha.
In the next year, Dustin wasn't surprised to see Steve stopped dating other omega girls, and moved entirely to betas. Betas wouldn't clock him smelling so much like an unmated alpha, but the omegas in Hawkins would steer fucking clear, as would hopefully the alphas. Steve had nearly commented on it, Dustin heard it in his voice one night as he complained about a lack of dates.
"Omega girls don't even want to come over, since all of my shit smells like you." Steve had huffed, throwing a hat he'd left there back at him, but Dustin just blinked up at him, innocently. It took Steve a minute to realize he'd sort of given the game away. Betas like Steve was pretending to be, shouldn't be able to smell Dustin.
"... That's what they tell me, anyway." Steve added pathetically, looking away from him, but it was a bit too late.
It was working. Dustin was ecstatic, he'd gotten home and done a little dance with the cat.
And now? With Steve at his college? It was becoming unmistakable. They spent most of their free time together, which wasn't uncommon in Hawkins, but now with fewer friends around, they were practically attached at the hip.
Steve hadn't had a heat yet since he'd started, Dustin didn't have to guess, by now he could just tell from the level of inflammation Steve was experiencing, plus how much he reacted to Dustin's scent now. Usually, they were close, even when Dustin wasn't making a point of getting closer to him; but during his heat? Steve was far more affectionate, in a Steve type of way. Sitting closer, brief touches, hands on shoulders, arms, fingers ruffling his hair. Once, Dustin thought he'd heard the tiniest hint of a chirp that threatened to become full on purring, before Steve cleared his throat and got it in check. It was pretty cute, Dustin hadn't heard a real purr up close and personal before.
Steve's fingers tightened around his pencil, he was chewing on his lip, looking concentrated, but Dustin could see his eyes were not on the damn paper. Inside, Dustin thought to himself with mirth, Steve must be going insane.
"Those two are so cute," a voice broke the silence, and they looked up to see a couple girls pass. They weren't talking quietly enough to not be heard, and Dustin felt a dumb smile curl onto his face. They thought he was cute?
"Cute? They're about to jump each other, did you see how that alpha was doing? Touching his scent spot." The other girl murmured, before the broke into laughter and turned a corner. Dustin looked back at Steve, still smiling.
"They think I'm cute," he said happily, but Steve looked half sick, pulling his hand out of Dustin's quickly. "Weird they think you have scent glands, though." Dustin added, shrugging, before looking back at Steve's homework.
"You..." Steve got out, looking as though he was chewing on the word.
"Yeah?" Dustin asked, trying to keep up the oblivious act. "What's wrong?"
Steve pushed up and out of his seat, cheeks red, but clearly he was getting pissed. Dustin knew he needed to back off as soon as Steve got mad, and this wasn't the first time it'd happened, but it was the first time he'd been so close to his heat when it did. Dustin wasn't entirely sure what to do, but figured getting out of public was probably the best idea. Plus, if he didn't leave something scented of his in Steve's nest-to-be, Steve would steal something of his anyway.
"You want to go study in your room?" Dustin asked. "It'll be less crowded. I think we have an the materials we need."
Steve's fists balled up as he stomped towards the library exit, but just when Dustin thought he'd really pissed him off, Steve stopped. He was waiting for Dustin to catch up, which he did in a panic, flinging his backpack over his shoulder and running after him. He followed him silently until they reached Steve's room. He'd gotten a single room in the dorms, which normally would have cost way more than Steve could afford in tuition these days, but omegas always received singular rooms for free, which Dustin knew he could have pressed Steve about, but that was a little too straightforward in his opinion.
"So, which question do you want to-"
As soon as the door was closed, Dustin was being shoved hard into it. He was so startled, his backpack slid off, onto the floor. Steve's head was right next to his, bent down so he could tuck it into the crook of Dustin's neck - where an alphas scent glands were. His body was pressed in close, and-
Dustin stared across the room, heart pounding as he began to hear the heavy and constant thrum of a low purr coming from his friend. Oh, it was way more pleasant to hear in person than in movies. Was this it? Was this where Steve came clean?
"You're so..." Steve got out, rumbling in his chest never stopping. "Do you even know what you're doing to me..."
"What am I doing to you?" Dustin asked breathlessly, wrapping an arm around Steve's back - there were scent glands here too. All over the omegas body, unlike alphas who only had them on either side of their neck, and right at the base of their cock. Dustin rubbed comforting circles into Steve's back, where he knew the glands were. Right above the hip bones, they were warm to the touch, the poor guy was really going through it with his heat this go around.
Steve whined in his ear, and it was a more... arousing sound than Dustin expected.
"Alpha," Steve said quietly, breathing hard, and his dick jumped. Okay, maybe it wasn't a good idea to do this this close to Steve's heat. It might cross the line of friendly alpha to potential mate alpha.
"Steve," Dustin moved, pushing Steve away from him gently. "You're not thinking right, right now. I'll come back in a few da- oh my god."
Steve had slowly sunk down to his knees as Dustin spoke, and he was not at all expecting him to rub his cheek into the front of Dustin's jeans. "What are you-"
"You're always doing it to me..." Steve mumbled, sounding nearly drunk. "I thought you were mad at me for not telling you I was an omega, but then you kept doing it, you kept scenting me, leaving your scent with me when I was in heat. Every single time I was in heat... You keep touching me, but why won't you touch me when I'm in heat? Why don't you come claim me, alpha, I don't understand..." Steve got out, hands moving up to pull on Dustin's zipper.
Oh. Okay, so, maybe he had gotten a little ahead of himself. Sure, most of the omegan specifically traits were related to breeding, but they applied to bonding too, omegas would scent pack members regardless of secondary characteristics. It wasn't like it was strange for alphas and omegas to just be pack, to be friends, family. Dustin thought Steve would have just pushed him away a long time ago, if he'd crossed that line.
Because, Dustin never really thought Steve would want him as his alpha. Steve was still fairly popular, Dustin would see pretty girls on campus chatting him up fairly often. Steve never seemed interested in men, and never alphas, so he'd never even considered it a risk.
"Why don't you want me..." Steve got out, hot breath on Dustin's crotch, and his dick was currently directly negating Steve's comment. It very much wanted him. Steve pulled on the zipper, pushing Dustin's pants down with it, until his cock sprang out, already hard, and his knot was beginning to get that tense feeling. Steve made an appreciative noise in the back of his throat, before leaning in and rubbing his nose into the scent gland at the base of his cock, into a soft haze of curly hair.
Dustin nearly came immediately, reaching down to grab hold of Steve's head, a handful of soft hair in his fingers. "Oh my god, Steve, what are you-"
"Every day," Steve breathed out, before mouthing at the side of Dustin's cock. "Every day, you tell me I'm your omega, and every day you don't do anything about it. Every heat, I smell you in my nest, and I present for you, but you don't bite me, you don't come for me..."
Oh, he was about to though.
Steve moved slightly, one hand wrapping around the base, pumping it slightly, before he flashed a pink tongue that ran over the swollen head. It was only a few tentative licks, until Steve took it into his mouth. Dustin felt like he was anchored to the ground, just watching as an out of body experience as Steve fucking Harrington moaned around his dick. It wasn't even a very good blow job, Dustin had had better from nerds in summer science camp, but they weren't Steve.
"I wasn't-" Dustin felt light headed as Steve used his hand to squeeze his knot. "I didn't know I was- I thought I was pack bonding with you!"
Steve's brows furrowed, and he pulled off his dick, pre cum making his lips look wet and red. "... You don't want to be my alpha?"
He looked...sad?
"I didn't think you'd want me," Dustin said quietly. "You want me?"
Steve just stared up at him, big brown eyes working through some kind of thought in his heat addled mind. Then, he smiled, shaking his head, before running his tongue down Dustin's dick again, and back up to wrap his lips back around the head. Dustin guessed that was as good an answer as any.
Dustin clenched his fingers harder into his scalp, and pushed Steve further down onto his dick, until he hit the back of his throat. Dustin might not have the biggest cock out there, but he wasn't small by any means, and Steve began to purr on it. It was hard to stop himself from just fucking forward into the heat that was enveloping him. His hips jumped forward a few times, and Steve did seem to nearly choke once or twice, not seeming used to it.
It was all enough to sent Dustin over the edge fairly quickly, quicker than he wanted, but it was the sharp scent of slick that did him in. As soon as he realized Steve was wet from sucking his cock, that he was leaking, Dustin rolled his hips, fucking his mouth for just a minute, before coming. Most of it got in Steve's mouth, but it began to spill out, and as Steve pulled back and off, a stray rope hit his lips. Dustin whined as Steve licked his lips, swallowing it all back down.
"Holy-" Dustin breathed out, his cock only softening to about half limp, because Steve was still pumping it with his hand, thumb massaging Dustin's knot. Steve's free hand, had moved to the front of his own slacks, where he was rubbing at himself.
"More?" Steve asked, voice sounding ruined, and Dustin was very certain that he must have escaped from a lab somewhere, where he'd been created for the sole purpose of driving him insane. "I've never been knotted..."
Dustin was the one that snapped, pulling Steve up with a sudden rush of strength, before shoving him back towards Steve's bed. It was clearly already mostly made into a nest, with the way the pillows had ended up sort of diagonal, and the blankets were mixed in with mostly Dustin's clothing, a soft towel here and there, and this violently ugly stuffed teddy bear Dustin won at a fair and given to Steve as a joke years ago. Steve fell down into it, and Dustin suspected he was letting himself be moved around. Dustin might be stronger than he used to be, but Steve was more all around in shape, plus he had half a head of height advantage compared to Dustin.
Still, Steve fell back into the nest with a soft whine. Immediately he flipped himself over onto his stomach, raising his hips up until he was properly presenting for Dustin.
"These need to come off now," Dustin said quickly, grabbing onto the waist of Steve's slacks, before pulling them down his thighs. His ass was perfect, round, tight, showing off his years of playing sports. His thighs were thick, covered in light brown hair that grew thicker as it reached his inner thighs. The hair smeared where his legs had touched, the slick that was leaking out of him, running down his thighs, making his skin wet. Dustin could see it too, how his hole would flutter before releasing a wave of clear slick.
"Are you even on blockers anymore?" Dustin wondered to himself, because from what he'd heard, heats on blockers were just sort of annoying and generally unpleasant.
"No," Steve mumbled into his nest, arching his back to he could try to push backwards against Dustin. He was showing off his scent glands too, especially the one at the base of his neck. "No more, I want you..."
"I could get you pregnant, though..." Dustin said, pondering if he had any condoms in his pockets. It wasn't like he was expecting to get laid. He'd been expecting to help Steve with his intro to college calculus course.
"Please?" Steve said, in a small voice. Something fully broke in Dustin's mind.
"You want pups?" Dustin asked, feeling himself getting somehow harder than he had been when Steve was sucking him. He took himself into hand, rubbing the blunt head of his dick against Steve's needy slick wet hole. "You want me to knock you up? You want to watch over a bunch more little Hendersons? You want me to knot you?"
Steve groaned, hips bucking in reflex. "Stop talking, Henderson, fuck me."
He didn't have to tell him twice. Dustin pushed forward, until the head of his cock popped past the initial ring of muscles with little resistance. Steve was in heat, he was wet as hell, and yet he was still so dizzingly tight, Dustin had to take a moment to get his grounding, before pushing in a few more inches. Steve was practically mewing as he whined and moaned, which seemed out of sync with the guy Dustin had grown up with. It made it all the more a turn on, watching Steve Harrington lose his mind on his dick. By the time Dustin was pushing in his knot and becoming flush, Steve was panting, fingers curled tight into his nest, his other hand under himself, pumping at his own dick that hung heavy between him and the blankets.
"Alpha, Dustin, you-" Steve gasped out as Dustin gave an experimental roll of his hips. "Fuck, don't stop. I'm so full..."
"Nancy never fucked you like this, huh?" Dustin bit out, not sure where the bitterness in his voice came from. He loved Nancy. "No one has ever fucked you like this, have they?" Dustin rocked in hard, and Steve let out a little sob. "Not as good as me, your alpha."
He'd barely just started, and he felt Steve clenched and milk his cock as he came. That wasn't abnormal, from what Dustin understood. Omegas tended to cum repeatedly during the mating process, but it was a different thing to know that, to masturbate to the idea of it, and then to feel it physically. He didn't stop for it, he fucked Steve through it, until Steve's voice was climbing in pitch. The deep arousal gave way to beautiful cries of need and want, and Dustin would make good on it.
He adjusted them so Steve was more on his side, Dustin wanted to see his cum smeared across his stomach, wanted to see his face as Dustin fucked into him. And Steve, god, he was so handsome. So pretty, but not feminine at all, even with his face flushed red and his wet pouty lips spread open as he panted. His head fell backwards as Dustin increased his speed again, thrusting in hard and deep as he went. Steve's omegan cock filled back out again, quick with his heat, and it bobbed against his taut stomach.
It wasn't long until he came again, gasping, untouched. Dustin groaned, getting closer to wanting to pop his knot, but not yet. He needed to- Dustin pushed Steve back down onto his front, grabbing his hair again and pulling his head back, so he could bite down hard into his mating gland at the base of his neck. Immediately Steve was sobbing, coming once more, and his scent rapidly changed. He was a claimed omega now, Dustin's omega.
"Fuck, Steve, I'm going to-" Dustin panted out against his throat as his knot began to fill.
"Yes, fuck yes, oh god." Steve practically chanted until his words turned to nonsense as he was fully knotted. For Dustin, it was one long orgasm, unending until eventually his knot subsided; for Steve, it meant every time his muscles clenched around Dustin's cock, he came again, and again, until his spent cock produced nothing, yet his body was still rocked with silent waves of pleasure.
When finally, his knot began to subside, Steve rolled over and Dustin flopped down onto his chest. Wet and sticky with sweat, cum, and slick. Dustin pressed kisses into the skin there on Steve's chest, until he found a nipple. He lapped his tongue around it, tasting salt and sex on him, before sucking on it. Steve groaned, spreading his legs apart again, until Dustin pushed himself back in. He was mostly limp, but he could feel a rut hitting him.
"I'm going to fuck you until I can't move," Dustin breathed out against Steve's nipple, nipping and pulling at it as Steve's fingers dug into his back. "I'm gunna get you pregnant, I'm gunna-
Steve huffed, trying to find a comfortable spot in his bed, his stomach round with pups. Two, to be exact. Apparently twins ran in Dustin's family. Dustin kissed his nape, fingers running across the skin of his belly.
"You're so perfect," Dustin mumbled. "Can I-"
Steve felt a blunt cock head rub against his ass, to which he immediately raised a leg to let Dustin push inside him. He really couldn't bring himself to ever tell Dustin no, and Dustin always made it worth the trouble.
"Can't believe you..." Steve breathed out, breath hitching as Dustin began to thrust into a very good spot inside him.
"Hmmm?" Dustin sounded sleepy, and there was a good chance Steve would wake up with his cock still inside him. "Wha'i'do?"
"You spent three years scenting me, rubbing my fucking mating gland, and didn't know what it'd do to me... Some genius you are." Steve complained, turning his head as best he could to look back at him. "Fuck, right there, don't stop."
Dustin laughed a little against his skin, not even bothering to sound embarrassed. "Worked out okay, though. Right?" He gave a calculated thrust that had precum running down Steve's dick. "Gunna give you so many pups..."
Steve rolled his eyes, Dustin was still allergic to admitting he was wrong about anything. But, he supposed he couldn't complain too much, especially not as his mates' knot began to fill out inside him once more.
