#STMMM26 #steddie Day 8 - Naughty in the Upside Down Steve knows it’s a bad idea. Just because Eddie has those big, baby deer eyes and the sweetest alpha scent—slightly smoky, like a marshmallow that burned along the top, that caught fire at the end of a perfect toasting—it doesn’t mean he should

Day 8 Prompt - Naughty in the upside down - Stopper - 870 words #STMMM26 Maybe I'm Crazy archiveofourown.org/works/80827756

@stmarchmm.bsky.social day 7: collars after the third chapter of my favourite dead dove omegaverse steddie fic, Companion by Anonymous (aka @veiledeclipse.bsky.social), i was plagued by visions of steve in his new chastity belt & collar so obviously had to draw it. #STMMM26 #nsfwartbytukru

#STMMM26 - Day 7 - Collars Tonight was the night, Eddie was sure of it. They’d talked about it already of course, but he made sure Steve knew the ball was in his court. He was more than ready to be claimed since the very beginning, but he knew how important choice was to Steve, to all omegas.

Written for @stmarchmm.bsky.social March Mating Madness Day 1: Knotting #STMMM26 #steddie archiveofourown.org/works/80479931

#STMMM26 - Day 1 - Knotting The first sign Steve is pupped is that he’s horny. Hornier than normal, which doesn’t register for Eddie at first. Even right after a heat wraps up Steve will be begging for a knot, pupped or not. He’s physical and desperate tor affection. Eddie’s used to it.

ao3 may be down temporarily, but look on the bright side: you have extra time to work on your submissions now😬
