Summary
Sonic was an omega. Only Tails knew this, of course, because the last thing he wanted was anyone else to find out that the cocky Hero of Mobius was a pure omega, and a royal one at that. He didn’t act, look, or even smell like one, which was just the way he liked it.
Though maybe he shouldn’t have planned a massive friends trip to a very public festival a week before his heat was supposed to start…

learning to care for each other by StryderTheHedgehog
Fandoms: Sonic the Hedgehog - All Media Types

Summary
=
Shadow’s legs move before he can stop them, barely closing the door behind him as he rushes over, kneeling in front of Sonic to be eye level with him.
He can smell a change in Sonic’s normal heart rate. His heart is racing, even more so than it usually is.
The change in scent sends signals to Shadow’s mind; old, instinctual ones. Ones he hasn’t had in a long time.
HELP HIM! his mind screams. HE’S GOING TO FAINT! ALERT HIM!
He shakes his head, mentally. Sonic doesn’t faint; at least, not that he’s seen.
Sonic’s not Maria.
And this isn’t a medical episode (to his knowledge); it’s a panic attack.
Although, Maria had had a lot of those, too.
=
OR 3 times Shadow uses his old service animal training to help Sonic, and the 1 time Sonic is able to help Shadow.

Summary
“I kinda”—Sonic shrugs, laughing—“don't really remember a lot about last night.”
“Why?”
“Cause I was drunk.”
Shadow makes a disapproving sound. “Typical.”
“Hey, man, just 'cause you don't know how to let loose and have fun doesn't mean the rest of us can't.”
Shadow's fingers prod at the bite mark on his shoulder. “Is this your idea of having fun then? Someone chewing on you like you're some kind of toy?”
[Sonic deals with everything that happened on the Death Egg by not dealing with it. At all.
Honestly, what could possibly go wrong with that?]

Summary
“What are you drinking?”
The voice is deep and low, raised just a bit to be heard over the loud bump of the music coming over the speakers directly above them. Sounds just like his type, maybe the kind taller than him with big muscles and rough hands and–
Sonic has to physically stop himself from laughing when he glances over his shoulder. All of his hopes flush down the drain in his mind, metaphorical gates slamming back shut after ever so slightly cracking open.
It’s just some kid.
alt; Young Shadow absolutely obliterates DILF!Sonic.

Summary
It's been a year since Amy had officially confessed to Sonic, but he had only answered vaguely, never confronting the thought directly. She had waited long enough, and she needed answers. However, even if she knew they would at least stay friends no matter what, why was she so scared of confronting him?
