"You fool! You can't scare me, I'm immortal!" she spoke.

Ignoring the insult, I allowed myself a superior smile.
"I know. What makes you think I'd want to kill you?"

She was confused for a second, until the truth dawned to her.

"You sick fuck! What are you..."

She couldn't finish the question. Her scream turned into a gurgle as I crushed
her throat.

She was suspended by ropes on arms and legs, so she could only wiggle and squirm as I started carving.

By the morning she would have regenerated, I only had to make sure she remained bound.
