There is something so fucking cursed about getting a good couple thousand words into a work in progress only for your brain to IMMEDIATELY start plotting out another fic.
Anyway another thicc thighed athletic Omega Steve who is a total Momma Bear fic idea for you all (that is currently tormenting me because of course it is...) straight from the sleep fogged archives:
O!Steve and A!Eddie one night stand/short term casual hook up post Starcourt, which leads to Steve discovering around Christmas 85 he is pregnant, cue a series of unfortunate events for our favourite babysitter. (BONUS POINTS: they hook up in Indy and don't recognise each other, maybe a BDSM club or something where scents get mixed up and make it hard to discern individuals. Steve only discovers the baby's paternity by scent and running into Eddie later).
His parents find out and he is kicked out for good. Hop's 'dead" it's the well and truly winter and it is by complete accident that Claudia Henderson finds out and forcefully adopts Steve into her home. This saves him from being homeless and/or sleeping in his car however it does mean Dustin and Claudia along with Robin become overprotective as fuck over Steve.
Dustin is able to keep Steve's secret both about his pregnancy and living situation, although he has zero idea of who the sire of the pup is. Which makes his attempts to get Eddie and Steve meet all the more awkward for Steve to get himself out of.
Robin is the only person who knows Steve has found out Eddie is his pup's sire.
The lead up to season 4 remains as seen in canon with the exception being Steve is not actively dating. Instead, he is doing his best to keep quiet about his pregnancy and keep the pups (and the rest of Hawkins) none the wiser at least until he can determine what to do about Eddie, about his living situation and about how he is going to afford raising his pup because you know that man is determined to keep them.
When the UD shit hits the fan, Steve is then left dealing with several crises all at once, and the Upside Down is only one of them.
1. Eddie immediately clocks that Steve is his mysterious hook up/ still harbours unresolved feelings about their hook up when they meet again in the boathouse.
2. The discovery of Steve's pregnancy following the older teens getting out of UD following the Watergate shenanigans and a near feral Steve fighting for his and his pup's life (and turning Eddie on big time while he does it) leads to the pups and Nancy losing their shit not to mention Eddie.
3. Cue Eddie figuring out the timeline and putting two and two together. I am imagining a very stilted and awkward conversation between the two where they both decide to leave the big decision conversation till after they deal with Vecna.
4. Which then sees Feral O!Steve 2: Electric Boogooloo when Eddie gets himself critically injured. (I am thinking a mix of stubborn CPR administration with a shit tonne of various 'don't you fucking think about dying before I have our damn child Munson' followed by him dragging him out of the UD and an adrenaline fueled feral pregnant omega tantrum of epic proportions at the hospital which gets Eddie seen immediately despite the hesitation over the whole satanic panic).
And because I am a HAPPY ENDINGS ONLY in this household despite my love of a good bit of angst in my fics. They get their shit together while Eddie and Max are healing (Steve totally hasn't adopted Max after her mother has gone MIA or anything), and Eddie and Steve obviously confess their undying love for one another. Steve has the baby/ies, and Uncle Wayne gets to be the best goddamn Grandpa in the world. Claudia cries when Steve asks her if she is willing to be his pup's Grandma. While Max and Dustin argue over who is gonna be the better Aunt/Uncle to the baby/ies (Robin is equally as invested in the argument and often is found squabbling with the two of them over it.)
Joyce and Hop are the baby/ies acting second set of Grandparent's, a fact that bemuses Eddie given his history with Hopper.
