You were new to the family, your dad having just re-married after years of being single. And you were happy for him - though you felt something was strange with your new step-mom, you trusted your dad and wished him the best. But that strange feeling wouldn't go away, like a nagging in the back of your mind, no matter how much you tried to ignore it. And that feeling only grew with each day, as you saw things your father never did. He was just so in love with her, he was blind to how nasty of a person she truly was. And the town, it seemed everyone knew this too and avoided the family - including you. Everyone assumed you were just as crazy religious, but even if you said you weren't they were more scared of your step-mom and avoided you by principle.
One day, your step-mom asks you to come into the kitchen. She pushes a bag into your arms, dripping with what looks like blood and smells like old rotten meat. It was super gross, but she had this look to her that made you fearful of speaking about it.
"Take this to the basement."
She talked as if this was somehow all normal, as if there was no questioning her actions and her orders should be followed immediately. So, as you feel the gross cold blood soak into your shirt, you carry the bag to the basement. It was really gross, whatever was in it was not fresh and smelled so bad you almost threw up as you descend down the stairs into the darkness.
