Last First Impressions
steddie | omegaverse | mpreg | age gap
First impressions are often wrong. Steve's first impression of Eddie was that he was a crass older alpha with too many tattoos to ever possibly be gainfully employed. Eddie's first impression of Steve was that he was a young uptight omega who needed to get the pretentiousness fucked right out of him.
Their first date was an absolute disaster, but the one night of passion they spent together afterwards was a decent consolation prize... At least until the pregnancy test shows up positive a few weeks later.
-or-
Two people who hate each other decide to coparent a baby bump until they inevitably fall in love.

Rating: E Pairing: Steddie Word count: 15,758 @stmarchmm Prompt: dystopian society Summary:
Wayne grimaced, watching Eddie disappear into the house. "He's…feelin' torn up about this," he said. "And listen, you gotta be patient with him. If you—if anything—well, I live just across the way, in the trailer park. He can walk home to me, easy. If he ran he could be on my doorstep in two minutes, and he's got a key. So, you know, don't make him skittish. I might not bring him back to you, depending on what happens." Steve frowned a little. "I—I'm supposed to protect him. I wouldn't…I won't. Do anything bad, I mean." Wayne sighed. "I had him just about talked into this whole thing, you know, he—he does want an Alpha, and pups and all, told him he wasn't gonna find those things couch-surfin', and he had his mind all made up that it was gonna be fine, until he saw your file." Steve's heart sank. "We—we barely knew each other. I'm not sure we've ever talked." or in an Omegaverse world where people find their mates before graduation or are assigned a mate by the government, Eddie and Steve are assigned to each other in the late summer of '85.

Day 17 prompt - Pregnancy - Steddie
Steve loves being pregnant and growing their first pup. But now that he’s starting to show, everyone around him seems to think that he needs their advice and even worse, their judgement. He likes those two things a lot less and with Eddie away on a short tour, he’s sort of on his own just trying to keep calm despite the growing number of comments, advice and unwanted bump touches.
OR: The 5 times Steve does his best to power through and the 1 time he explodes.
Okay I'm working on one last thing for @stmarchmm and I almost had someone saying something about bathroom graffiti and suddenly realized- Are omegaverse bathrooms are gendered male/female or Alpha/Omega, or are there 4 bathrooms everywhere??
What about the children that haven't presented?? Probably just all in the Omega bathroom????

Rating: E Pairing: Steddie Word count: 2671 @stmarchmm Prompt: surprise heat or rut Summary:
Eddie headed into the store, and found Harrington in the back room. "Uh, hi. I'm Eddie. I'm starting today. Working. Here." Steve looked up from a stack of papers. "Oh. Um. Hi," he said, grinning. "I'm Steve. I thought I was gonna be working alone today." He brushed past Eddie, towards the computers. "Come on, we should clock you in." Eddie found himself a little dazed, drunk on the quick whiff of Steve's scent. Of course they'd worn patches in school, not that they'd ever interacted much anyway. Citrus and grass and chlorine, Steve smelled like a perfect summer day, and— Shit. Eddie was hard.

Knot-Heads
@stmarchmm 2026 - 31 Free Day
Eddie couldn't fathom how he got here. As the obnoxious party raged around him, he sat slumped on a couch in the home of the one and only Steve Harrington; the biggest knot-head to have ever gone into heat.
STMMM26 - Day 31 - Free Day
Sweet Cream
by StarsHideYourFires
After the insanity of acquiring a handful of pups during what is arguably the worst week of his life, Steve’s hormones get knocked out of whack and he starts lactating. He does his best to hide it, only to fail spectacularly.
He feels like a freak. It only makes sense that the school freak would be interested in what’s happening with Steve’s tits.

STMMM26 - Day 29 - Scent Marking
Max won’t ever say it, but she likes it, the way Steve gently and methodically slides his hands over her shoulders and down her arms, squeezing at her wrists with the slightest pressure to stimulate her own developing scent glands. It helps to mix their scents, mark them as pack, tell her she’s loved and cared for. She tells herself that she likes it so much because Steve smells like lavender and sweet mint. A little pocket of calm for her nose that lingers on her skin after a movie night or a ride home from the arcade.
Sometimes she goes a couple weeks without seeing Steve, everyone busy. Her mother’s scent marking is lackluster now, all the drinking souring her scent, the alcohol burning away any of her natural sweetness, and her friends do their best, but pup scents aren’t strong enough, all similarly powdery.
Then she’ll catch a whiff of Steve on Dustin and she has to bite her tongue to keep from growling. But Lucas always notices, taking her hand and allowing their scents to mingle. “You can always go see him, you know,” Lucas says, again.
They both know who he means by “him.”
Max shrugs, unwilling to admit she wants anything, least of all to be scent marked by the boy she wishes could have been her older brother.
They both know she won’t do anything or say anything, but the next day Steve will be in the parking lot when school gets out. He’s picking up Eddie, the van in the shop again, but Max knows he’s waiting for her, his arms opening easily for her.
I've Been Dreaming of an Alpha's Kiss
For @stmarchmm Day 31 prompt: free day! it's still the 31st where I am so I'm posting it! rating: G | pairing: Steddie | wc: 1277 Summary: Steve meets the alpha of his dreams. AO3
Steve nuzzled closer to the warm body holding him. The sea salt and sandalwood scent tickled his nose as he breathed in the mysterious alpha. Warm lips slid along his own, soft and sweet.
“Please,” Steve whispered. The man growled, burying his face in Steve’s neck.
“You’re beautiful,” a deep voice rasped. “Prettiest alpha I’ve ever seen.”
Steve whined, accepting the other man’s tongue into his mouth. He licked against Steve’s palette, practically devouring him whole.
Steve had never been kissed like this in his life. Birds sang, wedding bells chimed as Steve melted in the alpha’s embrace.
The bells got louder and shriller the longer they stayed pressed together. Steve furrowed his brows, suddenly annoyed the sound.
Why won’t it stop?
--------------------------------------------
Jolting upright, Steve gasps for air. Looking around in shock, he finds himself in his bedroom. Alone. The alarm clock blares, the same screaming from his dream.
It’s been the same dream for weeks now. The same alpha, the same ocean scent. It’s driving him nuts.
Grumbling to himself, Steve turns off his alarm and throws himself out of bed. He shuffles to the closet, as a stretch overtakes his body.
Normally, Steve wouldn’t think too hard about what to wear. The bakery he works at is pretty lax with dress code; and since he opens, he’s only in front of customers for two or three hours.
But as he pulls out his go to joggers and t-shirt, the strange alpha from his dream fills his head. Long curly brown hair, teasing smirk, lithe frame with hidden muscle…a shiver runs down Steve’s spine.
It’s odd. Steve knows he’s never seen the man before; but at the same time, he seems so familiar. The way they kissed… Steve lightly touches his lips.
He’s been with omegas, alphas, and betas alike; no one has ever kissed him like the alpha from his dream. Of course you haven’t, it’s a figment of your imagination!
Shaking his head at himself, Steve grabs his date night jeans. A size too small, they leave little to the imagination. He doesn’t want to get coffee on his nicer shirts, so he yanks on a light blue polo.
Checking his reflection, Steve admires himself. There’s a tasteful amount of chest hair peeking above his collar and his biceps bulge just a little.
I’m losing my mind, he thinks as he heads out the door.
Alas, all good things must come to an end...
This event is called 'Stranger Things March Mating Madness,' so our official last day is today. That being said, you guys know we like to keep a good party going as long as possible!
Didn't quite finish that one work you wanted to? That's okay, we're not picky about the timing. March Mating Madness is a state of mind, not just a month. As long as you guys are posting, I’ll be here to repost! The AO3 collection will also stay open until I remember to close it (last year's collection just closed last month).
At this time, it's unsure whether there will be a STMMM27, but never say never. We can gauge fandom interest early next year and see whether it makes sense to continue. For that reason, I highly encourage everyone to stay following the event accounts.
Thank you all so much for participating, whether it was with contributions of fics, art, or cheerleading! It's been a fun month and the Stranger Things omegaverse community is such a talented bunch of weirdos I love sharing a space with💛

Down Payment
Rating: G Pairing: Steddie (background, mostly about Steve and his parents) Word count: 2734 @stmarchmm Prompt: scent marking Summary:
"Stephen," his mother said, softly. "You have an Alpha." Steve bit his lip. His entire room smelled as much of Eddie as it did of him, had for a while. He had noticed the change, but hadn't thought much of it in a long time. "Stephen?" Steve nodded slowly. "I—yeah. I'm not dating around," he said, quietly. "Dad's gonna hate him."

Tabletop
Rating: E Pairing: Steddie Word count: 2266 @stmarchmm Prompt: monsterfucking Summary:
Eddie decided to consider this, stroking his chin, and then spoke as the dragon again. "What would you give me, for the princess?" Steve looked down at his notebook, flipping to another page as if he was checking his inventory, but then he offered, "My knot?" Eddie crumpled a piece of scrap paper and tossed it at Steve's head. "You don't even know if the dragon is an Omega!" or Steve's D&D practice game is not going fully as planned.
