Good Girl
The smell of putrefying flesh was almost overpowering, but it wasn't enough to deter the spectators. They were too fascinated by the sight they were witnessing to think of leaving.
A naked woman was spread-eagled in her bedroom. Her arms and legs had been pinned to the floor with blades of crystal. A girl was bending over her, lazily tracing incomprehensible patterns on her skin. Wherever the girl's fingers touched, the skin smoked and blackened as rot set in. The woman was almost out of her mind at the horror that was happening to her.
"You always told me that I was your good girl," her tormentor said. "So I was your good girl. Got good grades, did my chores, never stayed out late, obeyed you in every way. After Dad left, it was just the two of us and you said that would have to be enough. That all we needed was each other and we would be fine, as long as I was good."
She placed her palm against the woman's chest. The skin and muscles liquefied, releasing an odor that was foul beyond words. The woman moaned in pain.
"But," she continued, "it turns out being your good girl wasn't enough. You said you were lonely, and you needed a man to love you. Then Sam moved in, and you changed. Suddenly, you were the good girl, his good girl. You did everything for him. You were too fucking stupid to realize that he was a worthless piece of shit. You even joined the Friends of Humanity for him!" She touched the woman's nose almost playfully and the flesh decomposed within seconds, leaving a raw hole in the woman's face.
"Then, I found out that I was a mutant. I remember how you looked at me when I told you. Like I was a monster. But, still, I didn't think that you would do what you did. I didn't think you'd turn me over to Sam and his Nazi buddies. I didn't think that you'd let them hurt me. Because I was your good girl, wasn't I?"
"M- Mara!" her mother gasped. "Please. Don't kill me!"
"I begged, too," Necro said. "I begged you to help me. But you just stood there and you watched. You just watched, you stupid cow."
She knew her power and how to wield it. She was able to make her victim suffer for a long time. When she was done, nothing remained but a gelatinous mass of blood and tissue.
Rake whistled in appreciation at her handiwork. "Necro, when you make a mess, you really make a mess."
She smiled proudly. "My mother always told me to be good at whatever I do."
