Author's Note: First chapter, here it is… please, please, please review.
Chapter One:
The black cloud of evil shot out from the sewers, tearing open Sam's mouth, and speeding inside. Sam tried to fight it, but it was too quick. He felt a rush of helplessness as the demon inside him was controlling his every move and breath.
The '67 Chevy impala pulled up in front of Sam, Dean turning his cassette tape of AC/DC off and getting out of the car.
"Did you see it?" Dean asked his brother as he locked his car.
"It went in the sewers," Sam gestured to the ground.
"Good. Lets go," Dean handed Sam a book of exorcisms.
Dean held out his flashlight, pointing it around the stained walls of the sewage system. Sam flipped through the book, skimming over the exorcisms.
"This one says be at least 200 feet close to the demon," Sam told Dean.
"Well, where is it?" Dean took out another flashlight.
Sam looked over the sewer tunnels, watching a rat swiftly creep by them. Suddenly, he pointed to a tunnel on his left, "There it is!"
Dean raced into the tunnel, Sam quickly following him. They chased what they Sam said was the demon, ending up bumping into a wall. The tunnel led to a dead end. Sam stared at his brother, who was about to go back.
"Not so fast, Dean," Sam hissed, blocking Dean's way.
"Sam what are you doing?" Dean almost began to panic at seeing the strange grin on Sam's face. Sam didn't say anything. He just stood, his eyes turning darker. "Sam!" Dean yelled, grabbing his brother by the shoulders. Sam's smile broadened as Dean flew back, slamming hard into the wall. He couldn't move. He couldn't speak either.
"Dean…" Sam was talking, but not in his own voice, "That promise you made a long time ago? Remember? Well, now you have to do what I asked."
Dean stared in hatred at the demon that possessed his brother. He shook his head, "Never, you son of a bitch," he whispered.
Trapped in his own body, Sam watched in horror and fury as the demon ragefully squeezed Sam's hands around Dean's neck, choking the older Winchester brother.
