Your first Halloween in Ponyville... albeit they called it Nightmare Night, probably for reasons of copyright. After several hours of handing out candy from the porch of your humble cottage, you saw the gangs of cheerfully costumed foals dwindle to single stragglers. Eventually you waited alone, a single candy bar sitting lonely in your dish, searching the horizon for a final trick-or-treater who would never come. The laughter and chants faded from the wind-swept streets, and Equestria’s moon rose above the Everfree Forest at the edge of town, large and fearful, heralding the end of all playful and spoopy fun.

Now began the old Nightmare Night, a dark and forbidding abyss of time, when ghosts and monsters visited a world lit only by the pale silver of Princess Luna’s faraway lamp. Anycreature who dared to venture outside their home at this evil hour was certain to encounter terrors that would chill them to the bone... if they were lucky. The unlucky would succumb to the dark forces that roamed Equestria, and find themselves blighted with curses that left their lives forever changed.

You wrapped your coat tightly around your body and took the final candy bar from your now empty dish, unwrapping it and enjoying its rich chocolate taste. Turning at last to reenter your home, you suddenly spied three shadowy ponies out of the corner of your eye, trotting down the street and headed directly for your house! It was too late! You’d dawdled beneath Luna’s moon of terror, too slow to flee inside, and allowed the creatures of the night to catch your scent!

Fear kept you rooted to the ground, your final taste of chocolate slowly melting in your mouth as the three sinister shapes came closer and closer. You breathed a sigh of relief when dark shadows were lifted by your porch light. You saw before you not three vampires, nor three ghouls hungering for your flesh, but a trio of local troublemaking mares known as the Cutie Mark Crusaders.

All three mares smiled to see you standing before them, seemingly stricken dumb and immobile. “Trick or breed!” they shouted cheerfully.

“Y-you mean trick or treat, right?” you asked, somewhat taken aback. “There’s no more candy, but I could—”

“Naw, trick or treat is for little foals!” Apple Bloom scoffed. “We‘re doin’ trick or breed this year!”

“It’s an old Nightmare Night tradition,” Scootaloo explained, “where we mares go door to door, asking stallions to breed us!”

“Yeah!” Sweetie Belle added. “It’s even got its own song! Hit it, girls!” The three mares began a perverted chant:

Trick or breed! Give us seed! Fill us with the foals we need!
Zombies rise from their tombs! You rise too, and fill our wombs!

Your nose began to pick up the scent of mareish arousal in the cold autumn air as three ponies began to sway their hips in time to their naughty rhythm. Despite your better judgement, your dick responded in turn, shifting and swelling until you were pitching a very noticeable tent against the flimsy plastic of your own Nightmare Night costume.

The proposition you were being offered was hardly unappealing... yet it was utterly foreign to anything you’d encountered in your adopted home. The cheerful ponies of Equestria were quite free sexually, and you’d enjoyed the company of several mares in your brief time here. Yet downing a birth control potion was a requirement of every date you’d had. Never had there been a mention of fatherhood, marriage, or indeed anything more than a night of casual fun.

“He’s already hard, ladies,” Scootaloo observed, blasting right past the subtle and teasing flirtations you’d learned to appreciate from amorous mares. She leaned forward and sniffed your crotch, hiking her hips involuntarily as she did. “Mmm, big, too. I think we’ve found our breeder!”

“W-wait, please,” you protested. “I want to respect Equestrian traditions, but I barely know you! I’m sorry, but—”

“Aww, but we made costumes, just for you!” Sweetie Belle twirled about, flaunting her bare curves beneath a short white skirt, the nipples on her teats firm and quivering from the cold. “See? I’m a slutty nurse!”

“I’m a slutty dental hygienist!” Apple Bloom added, pulling the surgical mask down off her muzzle to reveal beautiful lips covered with bright red lipstick.

“I’m a regular nurse who just pulled a 36 hour shift, and I’m so tired that I just want to lay on the couch and get nailed!” Scootaloo explained. She collapsed on your porch in her drab blue scrubs, panting for breath. “Ugh, I had to change so many bedpans today!”

“Y-your costumes are very realistic,” you admitted, trying but failing to turn your eyes from the sight of winking clits and perky young plots. “I suppose I could breed you a little... it’s just a Nightmare Night kink, right? You’re not really trying to get pregnant?”

“Duh, o’ course we‘re tryin’!” Apple Bloom snorted. “How do ya think thestrals is born?”

Your eyes instinctively darted to the skies, where even now you saw the silhouette against the moon of a faraway cluster of Luna’s sinister bat-pony messengers, flying off to carry out the wishes of their royal commander. “Erm... the normal way?” you guessed.

“You’re new to Equestria, so we’ll explain it to you,” Sweetie Belle offered. “Each and every pony conceived beneath the moon of Nightmare Night is born a thestral, and sent into the royal household of Princess Luna!” The young unicorn sighed at the thought. “Ooh, it’s so dark and mysterious... and arousing!”

“Yeah, the foals ain’t gonna be our responsibility! We just gotta find a stallion, get knocked up an’ pop ’em out! Luna takes care o’ the rest!”

“Luna requires that every mare do ‘trick or breed’ at least once, but we’ve never been able to find the right guy.” Scootaloo looked up at you with a begging expression. “Please, won’t you give us the foals we deserve?”

“We know you have what it takes to satisfy a mare,” Sweetie Belle murmured with a flutter of her eyelashes. “I heard all about you from my sister.”

“An’ mah sister...” Apple Bloom added.

“And the mare who works in the projection booth at the movie theatre!” Scootaloo concluded.

“Wait...” Apple Bloom scratched her head. “Why was you talkin’ with Focus Puller bout sex?”

“N-never mind why, I-I just was!” Scootaloo stamped a hoof and regarded you angrily. “Now, are you going to invite us in and make us mommies, or do we have to go back into the cold and dangerous Nightmare Night, looking for another stallion who’s willing to help us fulfill our royal duty?”

What man could resist this temptation? To make love to three beautiful women, impregnating them without a care for the consequences? If such a man existed, you didn’t know his secrets. You dove straight in to this temptation, succumbing in an instant to the mysterious, sexy ways of the magical land you now called home.

You opened the door and gestured the three mothers-to-be inside. “Come on in,” you offered hospitably. “Get out of the cold, and I’ll heat up some cider to warm you up.”

“Thanks, but we’re already ‘warm,’” Sweetie Belle snickered.

“Yeah!” Apple Bloom cheered. “Pipin’ hot, an’ ready ta get family-fied!”

“Cutie Mark Crusader Broodmares, yay!”

As the three young mares eagerly trotted into your small cottage, you suddenly hesitated, one last worry leaping to the top of your mind. “W-wait...” you stammered. “You girls are over 18, right?”

“Dude, we’re 23!” said Scootaloo.

“I’m in grad school!” Sweetie Belle stated proudly.

“Dang, how old did ya think we were?” Apple Bloom scoffed.

You sighed with relief, the last barrier of your reluctance had fallen. As the three mares playfully argued over which of them deserved to have her womb seeded first, you closed the door on Nightmare Night and carefully turned every lock to protect you against the chill and noises outside. You were safe for another year: free from Luna’s wrath, the night’s dark visitations, and any and all life changing curses.

Or so you thought...

Two months later...

In the candlelit hall of the Palace of the Two Sisters, Twilight Sparkle and Luna frowned fiercely at you and the CMCs. The four of you stood awkwardly before the two royals, heads downcast with shame.

“Girls, we are very disappointed in you,” Twilight said with a shake of her head. “Yes, Nightmare Night is a traditional time for pranks, but you went way too far this year.”

“And thou!” Luna bellowed, pointing a merciless hoof at you. “Thou actually believed their dumb story about how thestrals are conceived?”

“I-I didn’t know!” you defended yourself. “This is a magical land!”

“Tis not that magical!”

“Do you have anything to say for yourselves?” Twilight asked the CMCs sternly.

“We’s real sorry, Twilight.” Apple Bloom rubbed her swelling barrel and groaned. “All them hentai doujins made it seem like bein’ bred was nothin’ but nonstop fun!” She moaned with pain. “Ugh, these cramps! We done learned our lesson, eeyup...”

Scootaloo retched and held a hoof over her mouth. “Nopony told me about the morning sickness!” she complained.

“My figure is ruined!” Sweetie Belle weeped, looking back at her ever widening plot. “Cocks are just like chocolate — a moment between my lips, a lifetime on my hips!”

“H-hey, I think you still look pretty,” you tried to comfort the sobbing mare.

“R-really?” Sweetie Belle eagerly rubbed her chubby body against you like a cat, the fountain of her tears drying in an instant. “What part of me do you think is the prettiest?”

“I suppose you’ve brought your own punishment upon yourselves,” Twilight mused. “Maybe next time you go slutting about, you’ll have the sense to use protection. Fortunately, the male you seduced has agreed to take responsibility, so that your foals don’t end up in Equestria’s overcrowded orphanages.”

“I have?” you blurted out. Withering beneath the deadly stares of the two authority figures before you, you instantly changed your tune. “I mean... that’s right, I have! I totally have!” After all, these mares were carrying your foals! Even if the way they’d been conceived was less than wholesome, how could you be so cruel as to abandon your precious children?

“Very good,” Twilight commented. “You have until the end of the year to get married, and file form 3110 to register your herd.”

“The end of the year?” you cried out. “But it’s New Years Eve!”

“Better get to it, then,” Twilight snapped without sympathy. “And get a job, for pony’s sake! You’ve got three wives to support! I hear Barnyard Bargains is hiring...”

“A herd with this feller?” Apple Bloom looked at you and bit her lip. “Well, that ain’t the worst thing ta ever come out o’ our pranks.”

“Yeah, I get to live with my best friends and a hot human?” Sweetie Belle’s muzzle was now broadly smiling, her tears long forgotten. “I’d say the Cutie Mark Crusaders have pulled off another caper, girls! Let’s go and celebrate, with more sex!”

“I don’t even want to think about sex right now...” the nauseous Scootaloo moaned. “Except maybe butt stuff. Ooh, yeah, that sounds great, actually! Butt stuff, please!” The petite pegasus waggled her plot at you hopefully.

“I think that can be arranged...” you whispered with a suggestive finger scritch on Scootalo’s rump. Yet before the four of you could celebrate your somewhat imposed togetherness, Luna caught you up short with a deafening snort and a fearsome whinny.

“Now, as for thee.” The Night Princess looked you in the eye with a burning contempt. “Since thou art so interested in knowing how thestrals are conceived... tonight in thy sleep, thou shalt accompany me to my palace of dreams.”

“That sounds fun, and not ominous at all,” you stammered optimistically.

Luna loosed a dark and evil chuckle. “During my thousand year absence, I fear the number of my servants hath dwindled greatly,” she explained. “My noble warriors clamour loudly for a proper stud to swell their ranks... and their bellies.” Luna’s hoof pressed against your crotch, and you found yourself growing once again, despite yourself. “Hrm, yes, thou shalt make quite a carnal feast for my winged horde. Mayhap I will even indulge in a foal or two, myself.”

“Th-thank you, your highness, it would be my p-pleasure to serve you.” You managed to force out the words you knew the pushy princess wanted to hear, trying desperately to navigate the dangerous path you’d been placed upon by a seemingly harmless bit of fun. Both Luna and Twilight nodded with satisfaction as you accepted your place in this strange new land. Nightmare Night was long over, but it seemed as though for you, the nightmare was just beginning...

Dang, I hope Sweetie Belle doesn’t have to drop out of grad school!
