"Please?" The word's barely more than a whisper.

She pinches Sin's right nipple hard, and thrusts her tail at the same moment, smirking down at her. "Please what, my pretty little prey?"

"Please," she enunciates very carefully and clearly. "Please spear your knife into me, claim me, carve into me, pierce the heart of me — " 

Her voice rises and gets more fervent as she goes on. 

"Please stab me and take my life," Hyacinth finally confesses. "I want to die on the end of your knife..."

Her tail picks up speed and a wicked grin splits her face. She thrusts and thrusts into Sin's pussy, the length of her tail stroking back and forth across her clit. She lines the tip of the knife up precisely, just a bit down the inner curve of Sin's left breast from her areola.

"With pleasure, beautiful Hyacinth. Tell me the moment you start to cum."

"Oh. Oh fuck —"

Hyacinth shuts her eyes and breathes slowly, overwhelmed by the fear of the lethal blade — but after three long breaths she reopens them and fixes her gaze on Hailey's. 

"Yours," she gasps, her breath hastening, her body arching up as she offers herself to the knife. "Yours, yours, yours, close, close, please, Hailey —"

She cuts herself off and grits her teeth, hoping against hope to stave off the encroaching orgasm, but it's no use. 

And in that same moment, she plunges the blade into Hyacinth's breast, stabbing deep, between the ribs, piercing directly into her heart. She thrusts her tail even harder into Sin's cunt, and slides her free hand down to stroke and finger Sin's clit, the length of her tail rubbing along her own folds. She gasps as she raptly watches Sin's face.

"Mine," she murmurs. "My Hyacinth, my Sin, my beautiful prey."

The stab falls, sharp and bright and searing —

It's quick. Like she wanted it. The tearing pain and the incredible pleasure roll through her as one force, tearing her apart from her heart outward. Her heart stops, and darkness creeps in.

It hurts. It hurts so much. But she goes with a slight smile on her face, and her gaze never leaves Hailey's until it goes completely sightless.

Hyacinth doesn't stir. Her gaze is faraway, now.

Hailey's right behind her in orgasm, gaze locked with Sin's as they both cum and Sin fades.

The next thing Sin sees, when the darkness clears, is wood. She's curled up in something round and cushioned — maybe a basket? — with her tail in her arms and several cozy blankets draped over her. Above and around her is something large and wooden, perhaps a desk. She's unbound, just cozily enveloped in warmth and softness.

She lays in the basket and marinates in warmth for a long while. 

She's died. She's died and gone to heaven. 

Very eventually, she uncurls from the basket, gathers the blankets around her, and gets up to inspect the room.

The room is well-lit, with soft rugs over a hardwood floor, a nice chair by the desk, and a few more by the bookshelves that line the walls. A fancy fountain pen rests in a pen holder atop an expensive-looking leather blotter on the mahogany desk. There's a single door into the next room.

She seems to be wearing clothes now, beneath all the blankets. But she keeps the blankets anyway when she goes into the next room.

There's a blonde with a messy bun in an oversized sweater and shorts curled up on a very plush-looking couch, and two overstuffed armchairs. Out the windows is a forest, the ground sloped as though they're up the side of a mountain, dense with enormous, old-growth spruce and pine trees.

She looks up at Sin with a smile. "Well hi."

"Yeah, um, hi." She ducks her head. Gosh this is embarassing. "... I figured it was best to... do it in a controlled way first, you know." 

She runs a hand through her own hair. "Still can't quite believe I actually went through with it."

"Yeah. I'm honestly impressed. Pretty sure you made Hailey's decade, too."

She shakes her head and cleans her glasses on her sweater, then asks, "How're you feeling, after all that?"
