You blast apart the dark flesh and tendrils, forcing the heart into the open.
Grindstone steps up, slowly playing with the many-bladed instrument in her hoof. She licks her lips with a sharp gleam in her eyes.
She then violently kicks the blob of meat a few times until she finds Nightstrider's face, which she grasps and pulls out
"I want to see your face…"
She then slams the face against the floor, and slowly, softly begins inserting the instrument into his heart.
There is no way to truly describe the sound he makes as she starts turning the handle, making the blades expand outwards, slowly tearing and ripping the exposed organ as it is forces far beyond its limit of stretching.
The unholy shriek of agony and terror, amplified by the demonic echo, is enough to make your hearts miss a beat.
But she simply drapes herself over the writhing mess
"Sshh… I've only just began."
She then violently shoves the entire unfolded device deep into his chest, and begins churning and massaging it, deeply enjoying every moment
"Yes… it is all I ever expected it to be…"
She then twists the handle the other way, making a loud, wet snapping sound, and throwing her entire back into an arch, rips out his still beating, tar-black heart.
She observes it as it oozes over her coat, panting and softly purring.
Nightstrider's head slams down with a final scream. He is dead.
