After a party, two rivals wake up in bed with each other. As time passes, they wake up to each other more and more often. Eventually Shadow learns he cannot leave his new 'mate' because of a twist of science, Sonic's belly becomes heavy with Shads' unborn children

Being of different planets and different species, can you still love eachother?

Sonic and Knuckles are sent to a new planet called 'Neron' after a fight with eggman. There they meet a nice girl named Bunnie Rabbot who tells them about Neron and the neronas and helps them while they're there.

A certain black and crimson Nerona gets an interest in Sonic, and so the story goes.

Shadow is OOC but it's necessary for this story and I'm almost sure you'll like it. My first fic, read and enjoy. ^^

Sonic tries to make a contract with the Angel of Death, Azrael. However, he messes up and makes one instead with a demon named, Shadow. Alright, maybe he can work with this. Wait, you're a Incubus?
