My first real attempt at a serial killer!AU, so warnings for murder, implied non-con, and fade to black. Also, this is a Muggle!AU.
Very loosely based on the serial killer couple Paul Bernardo and Karla Homolka.
Lethal Love
Daphne primarily showed affection by bringing Blaise new "toys" to have his way with. She knew what happened when he tired of them, but she didn't care. She got as much of a thrill out of "disposing" of them as he did; maybe even more. It was hard to say, though, as they both enjoyed it immensely. All Daphne knew for certain was that it had all begun with her own sister, Astoria...
...
Two year ago:
"Daphne? Where are you taking me?" Astoria asked. There was a blindfold over her eyes, and Daphne held onto her arm to guide her.
"I'm about to change your life, Tori," Daphne responded, leading her little sister into the bedroom where Blaise was waiting.
She pulled off the blindfold and watched as Astoria surveyed her surroundings.
"I don't understand," the younger girl said at last. "Why am I in your bedroom, Daph?"
Blaise grinned. "You're here as my present, love."
"Your—" Dark hair whipped through the air as Astoria turned to stare at Daphne. "What have you brought me into, Daphne? What's he talking about?"
"Relax, Tori," Daphne said soothingly, hoping to minimize the note of fear in her sister's voice. "There's no reason to be afraid. Blaise won't hurt you."
Astoria swallowed. "Promise?"
"Absolutely," Daphne said, taking her sister's hand and leading her to the bed.
That promise had been a lie, although Daphne didn't know it at the time.
...
Daphne awoke to Blaise shaking her. Years later, she would still recall how calm he was when he told her that her sister was dead.
"What do you mean, she's dead?" Daphne whispered. She twisted around and looked at her sister. Astoria looked as if she could be asleep, but on closer inspection, there were dark, angry bruises on her neck. "What the hell, Blaise?"
"She wanted me to choke her," Blaise shrugged. "Auto-erotic asphyxiation, you know."
Daphne didn't understand how he could be so nonchalant about the whole thing. Astoria was dead. "I—she—what the hell are we gonna do with her?"
"We'll just say it was an accident," Blaise replied. He leaned over and pressed a kiss to Daphne's lips. "Come on, darling, no one would ever suspect us."
Blaise was right. The authorities chalked Astoria's death up to a freak accident, and Daphne and Blaise moved on to new ventures.
...
Two years ago, a few weeks after Astoria's death:
"Try it, Daph," Blaise urged, removing his hands from the unconscious woman's neck. "It'll give you a high, being in control of someone's fate. Being in control over whether they live or die."
Daphne hesitantly placed her own hands on the woman's neck. It was still warm, a reminder that she was still alive. She couldn't remain that way, however, if Blaise and Daphne wanted to continue their deviant activities. They couldn't risk her reporting what they had done.
"Go on, baby, you can do it," Blaise whispered.
Daphne took a deep breath and squeezed.
...
Present day:
Daphne smiled at the young woman who was loading groceries into her car. "Excuse me, miss. I need your help. I seem to be having vehicle trouble, and I was wondering if maybe you could take a look?"
"Of course!" The unsuspecting woman closed the boot of her car and followed Daphne over to the green SUV. "What seems to be the—"
Daphne reached into her pocket and pulled out the little penknife she kept there. "Don't scream," she warned, pressing it against the woman's back. "Don't even cry. If you show any signs of distress, this knife goes right through you, got it?"
The woman whimpered, but remained otherwise quiet as Daphne forced her into the backseat of the car.
"Hi, baby," Daphne said, grinning at Blaise, who sat behind the wheel. "Ready to go?"
He nodded and started the car. Daphne climbed in and sat beside the other woman, keeping the tip of the knife pointed at her the whole ride home.
...
Daphne tied the orange scarf behind the woman's head and smiled triumphantly. "That ought to keep you quiet, hmm?"
"Mmph," the woman said, struggling against her bindings. "Mmprgh!"
"Well done, baby," Blaise murmured, wrapping his arms around her from behind. "I'll be sure and reward you with a little something later."
Daphne chuckled and turned her head so that she could kiss him briefly. "I can't wait. We really shouldn't ignore our guest, though." She pulled away from him and knelt in front of the bound woman. "I hope you're tougher than you look. It's so much more fun that way."
The woman's eyes widened in fear as Daphne laughed. It was so easy to strike fear into the hearts of others, so easy to bend them to her will and then make them suffer. She loved to torment them. She lived for it.
And anyone who had the misfortune to fall into her path? They died for it.
...
Daphne glanced over at the woman who lay on the floor beside the bed. She was now still and unmoving. A few minutes of slowly tightening the scarf around her neck had drained the life right out of her, and Daphne had never felt more powerful and in control.
"Beautiful," she whispered, rubbing her arms to quell the goosebumps on her skin. "We've practically preserved her, Blaise."
Blaise peered over at the woman, too.
"You did a wonderful job, Daph," he purred. "You were made for this whole killing thing."
Daphne tossed her dark hair over her shoulder with a giggle. "Why, thank you, darling." She pulled the sheet off of them both, then raised an eyebrow at him. "Now, don't forget that little something you promised me."
As her husband rolled on top of her and began to kiss his way down her neck, Daphne sighed happily. It was time to relinquish a little control and let Blaise take over.
There would be time for more killing tomorrow.
