Summary
He hadn't been mistaken, Sonic's eyes changed into hypnotising rings of black and white. The hero chuckled, sharp teeth on full display. Were they always this sharp? Shadow licked his lips subconsciously.
Energy zapped between them, almost like Shadow's chaos powers were harmonising with the cyber corruption. It made the hybrid’s fur prickle, a warm current flowing through his body.
Or; Cyber Sonic is horny.

Summary
"What are you waiting for?" Gabriel sounds breathless, a desperate plea on the edge of his voice. "Strike me down Machine! Kill me, bathe in my blood and let it fuel you long after my death!"
V1 doesn't need be told twice. But its audials alert it to something shifting, an all encompassing background noise that grows louder with each passing second-
kkkkrrRRRAAACK-!
The sky splits open with an ugly tear. Inky black void spills forth into Treachery's cloudy sky. Both machine and angel freeze, spinning to stare in horror at the crack in space.
-
Treachery collapses and Hell decides she has time for one last show, trapping her two precious actors within the bowels of Fraud.
Hell is dying
Gabriel is alive
V1 is loved -

Summary
Sonic is unraveling under the crushing weight of something that claws at his speed, his vision, and his pride. Alone but refusing to look fragile before Shadow or anyone else, he pushes himself to the brink. He’s fighting not just Shadow, but his own body asking him to stop.
Or, Sonic refuses to admit he’s got more than a headache. Shadow doesn't buy it.

Summary
"I didn't like being the only one—being touched," is what Shadow eventually settles on. "But I did like…" He gestures between them, hoping Sonic will understand.
Sonic huffs, the sound tinged with disbelief. "Let me get this straight. Whatever the hell you wanna call that little freakout just now…" He waves the hand not currently keeping Shadow at bay vaguely in his direction. "It happened because you weren't reciprocating?"
Put like that, it sounds stupid. Even so, Shadow nods. "Yes."

Summary
Arthur was always the one in control—until tonight. Tonight, he asks. No, begs for Lancelot to take him, to ruin him. To climb into his bed not as a knight sworn to serve, but as a man, hungry and aching to worship.
Devotion never looked so ruinous.

Summary
Sonic would only need to hibernate for three months.
That’s what he had to keep reminding himself as Sonic went kicking into hibernation. His only other comfort, besides a cozy burrow hidden away from the prying world, was the favor he’d asked of his long-time rival, Shadow. With hybrid genetics and Chaos in his veins, Shadow wouldn’t need to bed down for the winter storm of the century.
Just three months without the blue hedgehog. That was it.
Shadow only managed two weeks before he went to check on him.
