Shadow lives in a cave on a mountain for several reasons:
One, he's not like other Mobians.
Two, he doesn't much care for people.
Three, no one tries to understand him.
Naturally, Sonic crashes into his life uncaring of any of these things.Series

Summary
"Test?" Sonic parroted, his own brows also furrowing. "Yeah, I did and...no. Wait. Shit, wait."
"Oh Chaos," Shadow hissed, flopping himself off and laying on his back beside Sonic. "You said you would."
"I don't know Shads, I've forgotten..." Sonic admitted quietly, also sounding flabbergasted and mildly mortified. "I was in a rush when Tails told me about Starfall Islands and it just slipped my mind—"
"Tomorrow." Shadow cut him off with a grumble, throwing an arm over his face as he exhaled through his nose. "You'll do a test tomorrow.”
"...Fine." Sonic groaned, knowing Shadow was right.

Sonic and Shadow were just friends with benefits. After one careless night together, everything changes.

Summary
Shadow let out a shaky breath. This was not what he was expecting. He expected a half assed apology, and for Sonic to stay uninvited and eat Shadow’s food. Not that he would have minded. But no… He wanted Shadow’s help? He wanted Shadow to… he gripped the counter behind him tightly, trying to relax his breathing. Yeah, he could do that. What were friends for? He could sit behind Sonic and press against his full breasts until all of that milk was spilling down his chest. Until he was trembling and squirming under Shadow’s touch and his chest wasn’t the only thing that was wet—
