Do Alphas Dress Up As Maids For Fun? by boylick

Summary
Shadow knows he’s not that politically nuanced about the Mobian culture and how their values conform to their secondary gender and all that shtick, but he’s also: not a fucking fool, for starters.
“Come on, big guyyyy. I’m sorry.” The blue hedgehog looks up to him, pouting. His scent is so sweet that it’s assaulting his nose. Too sweet that it’s uncanny. “I promise I’ll make it up to you.”
Because no matter how much this newly hired staff is attempting to butter everyone up by playing dress-up with that stupid frilly strawberry-pink apron of his – Shadow knows better.
That’s an alpha pretending to be an omega.
Sonic is your typical average alpha trying to get by and lands a job as a prison cook. Chaos ensues.

Summary
Sonic shuts up. For a second. Then – “You know, this whole time I’ve been calling you the other hedgehog in my head, but a name would be nice. I gave you mine, twice, so it’s only fair.”
“Fair,” the other hedgehog repeats. Sonic follows her up the creaking steps of the house. It’s brighter as they go up, nothing like the dimness of the barely used living room and kitchen on the first floor. Less dust. Maybe she wants Sonic to look at the pipes of some bathroom up here first? Sonic opens her mouth to ask, because might as well since the other hedgehog doesn’t seem keen on giving a name, when the other hedgehog does speak up. “It’s Shadow. My name is Shadow.”
“Shadow,” Sonic says back. What a cool name.
(In hopes of earning some summer cash, Sonic responds to a classifieds ad about fixing pipes, plowing fields, and sowing seeds for an older anonymous omega. It did not mean what she thought it meant.)

Summary
They fly to the ground, Sonic landing right on top of the alpha. He scrambles to get off of Shadow as the dark hedgehog groans. “What the hell…?” He turns over and his face scrunches in anger when he sees Sonic. “Sonic!” He grabs Sonic by the bandana and yanks him close to his face to get a look at him. Sonic yelps and tugs at Shadow’s wrist, trying to get his bandana back against his gland, but—it’s too late.
Shadow’s brows shift from knitted in anger to knitted in confusion. He breathes deeply, scenting the air. His eyes widened as he looked Sonic up and down. “Woah… You really are a faker.”
OR:
Sonic has been able to live his life fronting as an alpha, but in reality, he’s an omega. An unexpected heat leaves him exposed to Shadow. Who gives in to their shameful desires first? And how will they manage the fallout between them and their friends?

Summary
In a world where mobians are born as alphas, betas, or omegas, Sonic the Hedgehog has always hidden what he truly is. It's a secret he's protected for years—one that could change everything. But when Eggman harnesses the power of the Chaos Emeralds to unleash a wave of primal energy, the balance begins to crack. Instincts rise to the surface, hard to control and even harder to ignore. As Sonic fights to keep the world safe, he finds himself more vulnerable than ever—not just to the threat of discovery, but to the feelings he's buried deep, especially the ones about a certain ultimate lifeform.

Summary
After the mission went wrong, Shadow... changed. No longer was he the biting and brutal rival that Sonic was forced to partner up with. After making contact with the unknown Chaos energy within an emerald their team had never seen before, he was gone. The once angry and biting hedgehog was a rut crazed beast that wanted only one thing. A mate.
Sonic swallowed.
He was so fucked.

Summary
Haunted by his past and seeking refuge in the small town of Green Hills, Shadow enrolls in the local high school, determined to stay under the radar until graduation.

With a tight-knit group of friends, a supportive family, and a reputation as the school’s track star, things are going great. Plus, he presented as an Alpha over the summer—life couldn’t get any better. But when a new omega student named Shadow arrives, Sonic is intrigued. Shadow is mysterious and secretive about his past, unlike anyone Sonic has met before. Despite his best efforts to stay focused on his own life, Sonic can’t shake the strange pull he feels toward the enigmatic new student.

Summary
The king rose from his throne. Instantly drawing the courts attention and silencing their gossip. “I have never been one to concern myself with our second genders.” He began. His deep baritone voice echoing through the room without the need to raise his voice. “Yet an unrestrained, powerful Omega poses a potential threat. Their unpredictable nature could clash with what I have fought to protect.” he extended his arm and his fist clenched tight. Causing a ripple of murmurs to go around the court.
“As of today, I hereby enact a new law: all unbonded Omegas of age will be required to form a union with an Alpha noble of their choosing. Whether that be pack or mate.”

Summary
Shadow already dislikes being an omega, a presentation unbefitting of the Ultimate Lifeform, but his unique biology lends to his heat cycles being out of sync with all other hedgehogs. For years, he's toughed it out alone and just dealt with it, only trusting his secret with his dearest friend Rouge. But, of course, his awful luck would land him in a situation where all of that falls apart. An unexpected storm, a sudden heat and a few unfortunate situations leave him stranded in Rouge's vacation home with the last person he ever would have wanted to see him like this. There's no way he deserves any of this— not the shameful reveal, not the humiliating vulnerability, and certainly not the acceptance and kindness Sonic offers him.
Age and circumstance have changed their dynamic, so maybe its time Sonic and Shadow reassess where they stand.
