Darkness surrounded Shining Armor, who was led blindfolded deep into the recesses of a crystal palace, into an area known only to those who were sworn to complete secrecy. He followed the winding stairs deep down into the chambers below. A draft tickled his fur and made him bristle. His heart thudded ever faster in anticipation, uncertain why he was directed here, or what awaited him. But since it was a request from his beloved he knew it must be important indeed.

His trots echoed all the way down, hooves from a pair of unknown mares on his strong shoulders, as they directed him onward. Occasionally he would shoot them a casual question, but they either responded with short evasive answers, or decided to ignore him completely. He shrugged and cantered onward. While the Crystal Empire still harbored many secrets, he'd never pursued any real answers, content to let his lovely Princess handle such tiresome affairs.

Suddenly his small entourage pulled to a stop. "We have arrived," said a well-spoken mare. Gently she removed the blindfold from his eyes, and he blinked several times, his eyes coming into focus as he looked into a massive bedroom decorated in reflective crystals that appeared to collect small traces of light and store them. Ahead lied a massive bed complete with silk sheets and curtains, a heavy dresser and mirror were placed at its side, and the air smelled of perfume.

He swallowed hard, tried not to leer. "Uh...what is this?"

The pair of crystal ponies smiled at him. They wore maid headdresses to match their lacy costumes, complete with garter belts and high-heels underneath. The pair of twins bowed low. "We are here to serve you at the behest of Princess Cadance, master. I am Foal-Bearer."

"And I am her sister, Wet Nurse." The pair of earth ponies were like a rainbow of colors, curvaceous yet transparent and translucent. Their manes were neatly trimmed into bobcuts. He shivered as they draped himself upon him. He felt their warmth, listened to their heartbeats. "We aim to please."

He shook his head, unable to take his eyes off them more than a moment, no matter how hard he tried. "I don't understand. I know Cadance wants me to be happy, but isn't this a bit much?"

"Nonsense. We were selected by Princess Cadance herself to fulfill this sacred duty. We sacrificed our old names and lives to serve Equestra. And who says we can't take comfort and pleasure from the act? After all, you are an incredibly handsome stallion of immense status."

His chest swelled at such brazen praise. He couldn't deny a twitch from his nethers at the thought that they were willingly to bed him at his leisure. Even so he the idea of lovely mares reducing themselves to mere breeding stock simultaneously aroused and profoundly disturbed him. "But why? Did Cadance really set all this up simply to help keep our marriage spicy?"

The pair shook their heads in unison. "It's more than that. The Princesses foresee a war far off in the future that engulfs all of Equestria. In order to survive we require the best. You are a powerful and noble unicorn. Your innate magic will likely be passed to any offspring, especially once proper preparations are made. Your foals shall be raised to protect our homeland."

He shivered as they stroked his fur. "I'm not sure I'm comfortable with that. Children raised to be soldiers? I mean it's an honorable position, believe me, but will they have any choice in the matter? And besides, these are my kids! Will I even be able to visit them?"

Foal-Bearer nodded. "Of course. Granted this all must be kept a secret, but I assure you Princess Cadance has made all the necessary preparations to make certain they'll be well-educated and content. She's willing to make adjustments as necessary to make certain you're pleased."

Wet Nurse nuzzled his snout with her own. "Do not shame us. We want to bear your foals. Nothing would make us happier." The pair trotted over to the bed, and slowly bent over the side next to one-another, hooves used to raise their frilled skirts. Below were frilly panties that were partially transparent, and so thin their ponuts and vulvae were visible. Small moist spots were already forming about the crotch areas in anticipation. "Please, service us!"

Gradually the sisters started to make out. Their lips smacked as tongues danced and saliva was traded between them. Eyes heavy under makeup were lidded and their cheeks were flushed. His charcoal black cock twitched up-and-down as it started to push from its sheath.

A spark traveled throughout his horn which lit up in response to his spell, and he reflexively used his telekinesis to slowly draw their panties down the curve of their buttocks, at first to the point where their puckered anuses laid exposed, then their winking pussies, their swollen lower lips connected by a strand of marecum to the crotches of their now well-stained underwear.

It still wasn't too late to turn back. His wife would be disappointed but she'd understand and accept his reservations. Yet his muscular body seemed to move on its own, trotted closer as he lowered his snout, and breathed in the sweet musk of their exposed marehoods. "Okay," he mumbled with feigned reluctance and a dopey smile. "I'll do it!"

Wet Nurse's face twisted in need when she looked over her shoulder at him. "Take us in whatever order you like. We don't mind how. Use whatever holes you wish." The sisters used their hooves to spread each other's pastel pink pussies and assholes wide open. "Just make certain you finish inside us both at least once before the day has ended."

Precum dripped from his flared stallionhood as he playfully slapped it between the buttocks of Wet Nurse, only to deny her when she cooed as he did the same to Foal-Bearer. He rubbed his veiny penis against their holes, teased the sisters and himself, certain it would make their union all the sweeter. His tip smeared a bit of his clear excretions over their buttholes and labias.

Foal-Bearer shot him a desperate wide-eyed and open mouthed look. "Please, don't toy with us so much, master!" They swayed their hindquarters at him in a sensually subdued rhythm.

He slapped one hoof on Foal-Bearer's buttock and another at the same time on Wet Nurse's, smacked them so hard he left a red hoof-shaped mark as tender flesh wobbled under his touch. "Hey now, aren't I supposed to be the one in charge here?" An eep sounded from the twins as he spanked their cheeks about. They submissively lowered their front halves low as they could, stuck their asses skywards as they could, tails fully raised in submission to their Prince.

He couldn't help but smirk at the power he held over them. "Maybe I'll stick my thick, huge cock inside you sisters..." He groped their buttocks and continued to rub his shaft over their pert backsides. "But you've gotta do something for me too. I want to hear you beg for it."

"Please," the twins murmured. "Make love to us."

He shook his head. "Too formal. Too classy. I want to hear some dirty talk!"

They answered, "We need your cock inside us now! Give it to us!"

"I've started to feel a little limp." He smooshed their asscheeks. "Try harder than that!"

They simultaneously cried out in desperation, "Fuck us hard, master! Ravish us into complete submission! Batter our slutty foal-holes and shoot your loads deep into our fertile wombs!"

Unable to hold back anymore, he pushed Foal-bearer down by the head with one hoof into the sheets, while the other seized her maid costume, which he tore away in tattered shreds. She bit into a pillow as his member pushed into her folds in a small but messy spray of her liquids. Her swollen teats and well-rounded flanks bounced about as he started to relentlessly buck her, the bed shaking and squeaking with every motion of his vigorous hips.

Wet Nurse rubbed her clit and slit as she watched her sister be fucked hard. What the pair hadn't shared with their new master was their secret; ever since they acquired their Cutie Marks their sensations were always shared. Be it pain or pleasure they were in perfect tune with what happened to their counterpart, which enabled them to effectively double any carnal sensations.

The breeders whimpered as he traced their sphincters with his hooves to the point where they repeatedly clenched and unclenched in response. He draped his full weight atop the mare for the deepest penetration possible from this angle, felt his cock poke against her cervix with each frenzied thrust, felt his ears perk up while he listened to their euphoric lamentations.

Her lower lips started to needily suck on his well-buried cock in spasms, determined to milk his balls dry as the moist pink tunnel enclosed around his shaft. He seized up with clenched teeth and came a little on the spot, small plashes of his hot seed unloaded inside her.

Rather than let these sultry sirens win so easily, he seized her tail between his teeth and yanked it so hard she yelped, his sweaty muscular hips continuing to thrust hard as he could into her. The twins whimpered and squealed and freely wept tears of shameless joy. "I want your cum! No, I need it, master! Fill my fertile uterus with your powerful seed and inseminate me!"

He pulled her mane with a war cry and snort of his nostrils, sheathed himself balls deep, fired an explosive series of shots into her moist walls. Her love tunnel rapidly milked his vein-covered penis the entire time, for well over a minute until his throbs slowed down which left him dry.

"N-no fair, sister! Save some for me," whined Wet Nurse as the twins heaved heavy bosoms.

He smacked her derriere so hard she whinnied to put her back in her place. "Be patient. Master will handle that sweet little ass of yours soon!" He'd never spoken nor acted this way to his wife no matter how much she wanted it; he simply couldn't demean somepony he loved that way. However now proved a prime chance for him to fully cut loose at his leisure.

He sidled over to the cheerfully dazed Wet Nurse, poked the tip of his dick upon her ponut, then slowly sunk his way into her tight backside as he mounted her. He tore her costume away too like she was some wench from a cheap bodice-ripper novel. "Oh by Celestia's tits yes," she screamed blasphemously as he pumped into her. "Make your slutty toy take it up her ass!"

Foal-Bearer draped herself atop her twin, and her marehood continued to wink, which dripped a mixture of his fluids and her own onto Wet Nurse's tasty flanks. He drove himself all the way into her, felt her clench about his width, and a coo sounded from the twins who started to make out some more. Ever since their birth they had done everything together they could, from their showers to their first stabs at sexual experimentation. It's one reason why they had chosen this position once it was offered; it assured them a comfortable life where they never need part.

He wrapped a hoof around Foal-Bearer's swelled teat, and another about Wet Nurse's, rolled them about as he pinched and tweaked perky nipples. The latter lived up to her name as milk squirted from her pastel pink areola, beaded the tip which dripped over his masculine hoof.

His muscular buttocks were soaked in perspiration as he continued to slam into the maid. A part of him wanted to release inside her rectum, but he had a sacred duty to fulfill, one that the Princesses believed could lead to Equestria's salvation. He felt his stallionhood start to shudder anew, barely pulled free of her asshole in time, and hilted her pussy all the way as his dick found sweet release. His flared head painted her pink love tunnels white under a hot flood of spunk.

The twins whimpered and mewled, squirted all over each other and the bedsheets, which left a heavy stain that continued to spread, not to mention the sweet scent of their slimy pussies. He unsheathed himself from the second maiden, took a moment to admire his handiwork, as their vulvae continued to wink and drip in satisfaction. He possessively smacked their well-marked bottoms.

With all the potions they had taken to make themselves even more fertile there was no doubt he'd fathered more foals. Likewise they had taken similar substances to enhance the potency of their wombs, and better collect traces of his mystical nature, which would further enhance their offspring. He placed himself between them on his back, relaxed as they dreamily started to nurse his cock between them, determined to clean his dark shaft which still tasted of the horny pair.

He directed their heads up-and-down. Globs of semen flowed down his meaty altar to the point where he shuddered in satisfaction. They masturbated each other casually, licked, kissed, stroked, and suckled his royal cock, which twitched under their playful ministrations.

After they couldn't milk anymore from his dick, they started to swish and chew on all the spunk they'd lapped up, spit and drooled it into each other's mouth as they repeatedly traded his precious seed, savored its taste and texture like the potent mana it truly was. They opened their maws wide to show off his bubbly spunk and smirked as they happily swallowed it down.

His hooves cupped around their bottoms when he pulled them close to his barrel-like chest. They swooned and laid their heads upon his chest as they cuddled him. Slowly they drifted into a peaceful sleep. He stroked their manes as they quietly snored in his well-toned arms. But he knew they were merely the first of the breeders he would have to take care of.

To combat the darkness that was to come Cadance had prepared an entire harem of the most desirable volunteers to service the virile stallion. He would make it his personal mission to inseminate every beautiful mare on offer. After all the fate of Equestria was at stake. Who was he to say no in such a dire situation?

Author's Note

Just something quick I whipped up out of boredom. More will hopefully be forthcoming whenever time and inspiration permits! Not really one for making OCs, so just think of them more as generic background ponies that have been thrust into the limelight for a bit of clop.
