She's Mine! Sonic x (cat)reader x Shadow (sonic boom)

You are a cute Siberian cat mobian with two big fluffy tails that was created by tails' grandfather before he died. You were mainly his mother figure and took care of him till you met your bestfriend Sonic. Sonic was your sword and you were his shield, the two of you were each others protector, defending each other no matter the situation. He shows a side to you that no one has ever seen. The cocky and sassy hero that everyone knew was much softer around you. He was an absolute sweetheart and he made sure to check up on you every day and will make you rest if he senses a second of exhaustion. He has always had a giant crush on you and its very obvious but you being the oblivious cat you are, you didn't notice and only thought he was trying to be nice. Sonic has always been brutally honest, but always lies when it comes to his feelings about you. He's quite the Shy one I must say.

When Shadow first laid his cold blood red eyes on you he was starstruck. He fell in love with you quickly and got jealous when he saw you with Sonic and same for him. You befriended him and hung out with him throughout the week on certain days for months. What happened when both hedgehogs want you all to themselves?
