Cosmic Breed

An obnoxious grumbling solution the earth somewhere near the castle. Or, at least, in her ignorance, that's what Fluttershy assumed. They weren't at their cottage that time, nor did they ever want to be thanks to the events a year prior. Her daily schedule had morphed from tending the garden and her flock of mismatched animal friends to tending Twilight's courtyard.

She trotted through the lobby past the iron doors, turning her head every which way to find somepony. There had to be someone else that felt or heard or experienced the same quake as her. Wherever or whatever the reason it happened, she couldn't fathom an explanation. Earthquakes did not reach Ponyville. And Discord was not attacking because if he was, the sky would be looming masses of cotton candy dousing the earth with chocolate.

However frail she may have been, or however sensitive her overworked body may have been, she'd grown intrepid toward the shadows of the keep. Narry a day did she heed the warnings of the unmanned stations at the entrance of the basement, and more so did she ignore the fact that it was blockaded with a steel door not fourteen inches thick.

In her brief search for another face, she yelped as the keep broke into a tremor.

The most definitive noise, not even the rumbling or rattling of the chandeliers above, was the unmistakable hum of the basement entrance. That was the loudest, single most potent source of noise there. And without any worry, she undid the barrier beam just over the door and slipped inside.

Fluttershy's mane met tiny dust clouds loosened from the concrete ceiling. An odd discovery, she noted, wondering why the lowest floor's intregity relied on concrete rather than diamond or any other crystalline structure. She'd tripped over a few cords and cables on her way forward, dazed and somewhat loose in footing. Her nostrils were assaulted with the queer scent of potassium, plastic and something akin to nitrate, urging her to go deeper and find respite from the stark sharpness they carried.

Rumble. Rumble. Groan.

There it was again. She shambled over to a small closet area near the second turn, clicking the pressure pad forward. What she beheld in that darkness would never leave her.

It stood on two legs, scrounging for an answer to an unknown urge. An indiscriminate mess of various miscellaneous nothings coated the floor in jagged shapes and plastic containers. And though she wanted to turn away, flee to the ends of Equestria and legally change her name to Flower Smith, she was bound to the soil beneath her hooves. The anxious gravity collapsing her lungs and hindlegs would not dissipate.

And so too did her lagging mind comprehend it's form: a thin, pale human with a cassock caked in blood.

It gave pause and began sniffing.

Dear Luna.

An abrupt, joyous chuckling slipped past it's lips. And though she swore it's gesture was done to brittle her, it seemed entranced by her scent blaring in the dark. So it turned to face her, one eye closed and one bandaged to no end with gooey wraps. Beneath the eyes that needn't open to even consider her shape or form or expression was a soft, fang-heavy grin.

Fluttershy let loose a yelp as she backed into a broom.

And that was when it found her.

"O-oh no... N-nice Mr. Demon- Nice consensual sex... demon." She shook, stumbling backwards and falling on her haunches.

Oh shit.

Fluttershy whimpered as it stepped in and took hold of her hindlegs. The unspoken terror in her eyes was invisible to it's blind hunger. When it would stop or when it wouldn't do whatever ungodly things it did, nobody knew. She would be the first to find out. And already were her feeble limbs shaken with the same hopelessness as her watery corneas. So much so that her struggling resembled mild foreplay.

It panted against her muzzle and supported itself against the door behind her. It clicked shut and sealed her fate. The next thing she knew, her barren slit was tickling and stabbing with hot, prickling heat. Whatever size it was she hoped it couldn't get any thicker. An absurd volume of thick muscle forced her apart and drew a cry of shrill reluctance.

All she knew was how firm and decisive her rapist's ministrations were. They drove her forward inches at a time, sometimes pausing to grind the crown where it hurt, some times to taste how tight her marehood was. It leaned in and stole a kiss.

"W-wait-! No...!"

"F-fhhck..." Fluttershy whined, shivering deeply, desperate to curl up and shield herself from the onslaught of hot insertions.

No. She couldn't.

Pleasant heat struck the base of her lips as she felt herself clinging to her invasive mate. And though she bit her hoof in retaliation, she gasped as it pulled her forelegs away and pinned them to the door behind. Her soft flesh rippled and jumped every time it shoved inside. It left her lungs stabbing with anxious effort, forcing her to expose herself as it milked her cumpocket.

As much as she shut her eyes, it was harder harder to hide.

With a high bray, she thrashed as her hindleg jittered wildly. Fluttershy was losing her fight. From the way it kissed her cervix with countless coats of precum, to the way that same icky gunk melted her with throbbing tension, she groaned and managed to slip her hooves away.

Fluttershy did her best to shove her mate away, but it grew firm in handling her hips like handles. The human thing stuck it in and pressed their lips together, suckling her mouth muscle with its pharyngeal jaws. Her eyes winded and every inch of her body tensed. Fluttershy shrieked and fought to get it out of her; but as she jerked her body left and right she choked on her own breaths, grating her throat as it clapped deeper inside.

"Nmmmmhmmm! Stmmmhp...!" She whimpered, trembling wildly as her hooves curled sharply.

"N-nmmmhmm... nmmmhmhmm." She sobbed, burning bright red as she had her first orgasm in months.

It let her go and left Fluttershy a mess of shallow, stuttering gasps and aching flesh. She closed her eyes and rolled over, biting her hoof and letting it do what it wanted. There she could only attempt to make noise as it thumped her body back and forth. Forceful, staccato grunts and packets of air were stolen away with her body. A hard, squeaky cry echoed through the air as she collapsed forward, fidgeting everywhere as the monster yanked her tail and bred her.

"A-aaah no... No... You're not- You can't- I'm gonna pee-"

Throughout her core, all over her nethers and even in her cheeks, she was flooded with hot shame. How could anypony enjoy being used like a toy. Especially her. What would her friends say. She groped the dark around her for something to grab. Something to grip while she was taught to enjoy cock again.

"M-mmmmmh-! Nononono!"

Hot, shivering air blew out between her lips. A thick, painful ram stretched her cervix and forced her cum out. A series of vice-grip squeezes struck her body down there. It leased her femcum in narrow jets of breathless satisfaction. And as she creamed her mate's cock with her own special honey, she buried her muzzle whever she could. Then, she pressed her lungs empty in one, satisfied groan, shaking in odd intervals. Fluttershy could only lay there helpless to another helping.

"Uuuuuuuuhh..."

The thing on two legs held her forehooves as it mounted. It wasn't in, but the underside, bulging with a thick and pulsing cum vein, pressed between her folds. When her head was cranked softly to the left, her eyes went wide again. It stole another kiss. And another. And another. She glanced elsewhere with low, heavy lashes, indulging in something so baser and chemical as enjoying her desecration.

Her forehooves dug into it's cassock and she struggled to gain her breath. Every kiss, every inkling of spit they swapped kept her drugged down there. Whatever it was, the human thing drove her crazy. It wasn't as long as the last monster that took her, but it hit all the right spots and did all the right things to her body. Fluttershy barely realized she was fading out of consciousness. Instead, she slurred along with their makeout session, finally succumbing to yesterday's binge of Applejack Daniel's.

"Mnmmm... don't forget to wah her thm garhhm..."

Those words were all she could manage. He grinned softly in innocent amusement. Life sure was different than he remembered. The earth no longer harbored the stain that was mankind. Twas an entirely unique creature compared to Earth two centuries ago. Though he had much more to decipher, he decided to fulfill her post-coitus request and tend the garden. Surely no harm would come from watering a few petunias and local vegetables.

Carefully, with the utmost discretion in not leaving bruises or marks on his newest breeding mate, he carried her deeper into the den. There, the brood unit tucked her in and followed terran custom by placing a stuffed animal against her ar... foreleg.

The cool, moist air of the Chrysalis Den kept him subdued from any aggressive or mind-altering behavior. What happened earlier, he couldn't begin to understand. It was that stench clinging to her rich coat not an hour prior. Hopefully, no other equines or neighboring species were harboring the same scent.
