kill or be killed BxB

It was a dark Monday night. The moon was the color of blood, dark clouds covered the night sky not a star in sight. I sat under a tall willow tree my long black hair covering my blue eyes, tears streamed down my face as I held a black and white picture of my mom sitting in a wooden chair and my sister to her right her hand resting on mothers shoulder. They were in dresses and bright smiles on there faces.

Those days seem so far away. I sat there my back resting on the tree my eyes start to close my hand falling to my side, my eyes shut and I fall asleep.

Past-

"Sin, were are you!!" Screamed a far away voice. "Sin!!"

I laid on the cold dirt floor the cold rain hitting my sore face, blood dripped from my nose and lips. I tried moving my legs but they wouldn't cooperate, every bone in my body felt broken I groaned as I tried using my arms to sit up but failed as my arms bulked and my back hit the ground.

"I found him!" Screamed a women's voice. "Oh my god Sin...you look horrible." I felt a hand touch my cheek lightly. I slowly opened my eyes and found myself looking into the eyes of my big sister.

Her green eyes started back into mine, her long golden hair fell in her face as a smile spread across her pink lips. "Help is coming, don't worry little brother." She said as she  caressed my cheek. I gave her a weak nod as my eyes begun to close.

..............................

I heard a load gasp and my eyes snapped open, my mother was now standing there with my sister, my mothers arms were wrapped around my sisters. I was warm laying under a thin white sheet, a candle sitting beside me on a side table.

My sister stood frozen fear in her eyes as she and mother stared ahead of them.

My head slowly turned to see what had them so frighted. I was guessing a rat or spider.

But what I saw was never what I had excepted...it was him....The dark lord, the one that had almost killed me.

His dark black cold eyes started at my mother and sister like they were a piece of meat. I opened my mouth to scream for them to run but nothing came out. I tried sitting up but couldn't.

I was helpless, I coulden't do anything but watch.

The dark lord suddenly vanished into thin air. My sister clung to mothers arms for her life as tears ran down her face. He appeared behind her, I tried to scream but nothing.

His fangs popped out and dug into Anna's neck, she let out a horrifying scream then collapsed to the the floor. My mother rushed to her side only to be picked up by the demon lord, he held her in the air by the neck her feet dangling off the floor. I watched in horror as the life slipped out of her, her body fell stiff.

The demon let out an evil laugh as he dropped her, tears filled my eyes, I coulden't do anything but watch as my family was killed....they needed me...and I coulden't even help them!! Now there dead!

I clenched my fists in anger, as I started at the evil best standing before me kicking my mother and sister over and over. Then out of no were my voice came out as evil as the demon looked.

"STOP IT!!!" I screamed with rage. my body still woulden't cooperate it hurt even to try moving.

The demon's eyes snapped to me, a dark smile spread across his face.
