Cadence x Human Heart

Cadence gently rubbed herself, guiding her  hoof across her glistening, tight-

KNOCK KNOCK KNOCK

Cadence dried up like a desert in half a second, not that she moved from her position. Screw whomever interrupted her. "Come in." She stated plainly.

Shining Armour poked his head through and exclaimed, "I got you a present, honey!"

Cadence turned on her sprinkler....

"It's a new toy!"

Full power.

Shining lifted a box through the door, "Sorry, I've got to go to a meeting, can you do this on your own?" His nose met with the door very intimately, as Cadence opened the brown generic box.

"What," she stated more than asked.

Inside was a still beating, red, muscular organ with four holes in it.

It was a heart, surely, but not one Cadence had ever seen before. Pony hearts were romanticized and pretty, zebra hearts were as their exterior, and griffon hearts were hard and brutally strong. She learned this all very legally, through the proper mediums; rumours to the contrary are treason. Could this be a changeling heart? Why would Shiny give her that, and call it a toy, no less?

Cadence pondered what to do, how to react, when she realized that she always knew. The answer to all of her problems! She would fuck the heart and have an awesome orgasm!

Cadence began gently licking the heart, getting it nice and wet for insertion, as well as to practice her form.

She licked the top and slowly started to suckle on it like a babe to a tit. She began edging it towards the back of her throat, deeper and deeper in... until she gagged and spit it out like tobacco.

"Cthulhu fhtagn! How am I supposed to use this thing!?" She spat out the heart, along with a hunk of it that came off in her throat. Before her eyes, the heart regenerated the bit that was removed.

Cadence was overcome by a lust for power, as she realised what this meant, and how it benefited her. She could absorb its regenerative ability by consuming it, and then become invincible! But it wouldn't fit down her throat, and she couldn't chew it, it would regenerate in her mouth or throat,so she had only one option:

She had to fuck the heart into submission, then take it as a suppository.

It was the only way, really; at least for the sake of Plot Convenience, Celestia knows what'll happen if I don't appease her.

She held it upright with her magic, and got on her legs to ride it like bull. She penetrated herself with a grunt and began drilling it in- literally spinning it extremely quickly while pushing it up and down inside of herself. But it was too large!

Cadence lost control of her magic, hijacked by another being, and the heart dove into her. It tore through her uterus and flesh, shooting her original heart out of her body, and Shining Armour returned too late after finding out it was cursed, and saw it give love a bad name. He sat, and weeped...

Twilight sat at her table reading Battlefield Equestria, when Spike entered with a box.

"Twilight, I've got a present for you!"

"Go away, Spike, I'm trying to read."

"Fine, I'll just burn this book I got for you, then."
