Heading off on the Rainbow Road

Dash grinned, her eyes glowing pink, as she flew through the air. She felt so...free. Powerful. The artifact lodged in her loins was...amazing, the sheath it had given her thick and virile. She searched Ponyville from above- she was going to expand her harem. It would be big, and fertile, and filled with only the best. The best for the best, naturally. She began to spiral gently downwards in a tightening circle, having spotted exactly what she wanted-the now grown CMC, going home together from work.

She landed in front of them, flexing her wings before tucking them in again. "Heya, girls!" she grinned, the power she had gained already turning their brains to cotton candy before they could realise something might be amiss. "Glad I caught up with you!" she enthused, the trio stopping

"Oh, hi Rainbow!" Sweetie smiled, eyes tinted pink and relaxed. "Say...do you know where our sisters went? I haven't seen Rarity all day..." Apple Bloom nodded her agreement, looking just as Sweetie Belle did.

"Oh! Geez, sorry girls-we've all been building an awesome club, called a harem! It's where an awesome pony finds other awesome ponies, to have foals with!" she explained. "Your sisters have already joined, all of my close friends in fact!"

Scootaloo, her eyes the pinkest of the three, grinned, "Wow...that sounds like the best club ever, Rainbow Dash! How do we join?" she asked, the other two nodding.

"Yeah, it's gotta be good for my sis to have joined so fast!" Apple Bloom agreed. "Do we gotta like, do feats to join?" she asked, remembering the find a pet debacle.

Rainbow shook her head, smirking. "Nah...we've just gotta have sex!" she declared, "It's simple to be... inducted? I think is the word Twilight used, I've just gotta mount, fuck, and come in all of you, bare. Then you'll be pregnant, and will be officially in my harem,"

Apple Bloom frowned, "Pregnant? That sounds...kind of..." her eyes seemed to become unfocused. "Really dang hot, t' tell ya the truth," she admitted, her loins already juicing up under her red tail. Her tail raised, swaying back and forth. Sweetie giggled at her, unaware her own tail was swaying like a whore in heat.

Scootaloo jumped in place excitedly, her tail flagged all the way up and her cunt drenching her thigh fur. She might have been the only one who didn't need the artifact to convince her it was a good idea. "Having Rainbows foal?! This is gonna be amazing! And my best friends get to join in too!" she bounced around, Dash chuckling happily at her enthusiasm.

"Well...then I guess my number one fan goes first!" she declared, spinning Scootaloo around until her flanks faced Dash. Scootaloo gave her an uncertain look over her shoulder. "Don't worry about it being in public-only cool ponies that want to join my harem will come over. We won't be stopped," she promised, Scoots grinning and nodding, splaying out her back legs and making sure her tail was flagged up good and high.

Dash nuzzled Scootaloo's rear end, taking a deep whiff of the strong smell of cunt juice. She licked her muzzle clean, before mounting her number one fan. She sighed in pleasure, her thick cock extending out of her hefty sheath and swaying heavily. The other girls watched, sitting flank to flank, Apple Bloom using her hoof to gently rub Sweetie's folds, while the latter used her magic to gently tease and probe her friends folds in return.

Scootaloo shook in her excitement, hips rolling in anticipation of thick cock and foal batter. Dash lined it up, her flare pressing against the soaking pussy. Both their wings were at full mast, trembling in need and desire. Scoots moaned, trying to press back onto that mare impaler, but Dash kept her still with her hooves. She held her tight, cock sliding back and forward between the sopping wet lower lips, dripping onto the ground with an audible patter of liquid. Scootaloo moaned, begging as she wriggled her rump.

Dash grinned, and with a smooth thrust into the wet depths-and an audible squish-she was flush against the younger mare's cervix. Scoots gasped, pink tinted eyes rolling back in her head, legs trembling. It felt...amazing. No toy or stallion or mare had ever reached so far and felt so good. She had no idea the artifact lodged deep within Dash was the reason for it, and at this point, was far too under its sway to care. Each mare Dash took, each womb she filled, made her steadily stronger with the thing's power.

She grinned, her lust driven mind focusing on just one thing-fucking. Well, and making foals. She knew, from instinct, that she wasn't strong enough for the princesses...yet. But soon she'd have the power to make even Celestia kneel for her cock. She pulled out, thrusting back in again. Each pull was slow, so slow, but the thrust back in was heavy and fast, making Scoots legs quiver with each. Dash also kept changing it up, never the same tempo for long. Scootaloo moaned, trying to get Dash to go steady so she could cum-but Dash seemed to refuse.

She flipped Scoots over, still impaled on her girlcock, and began to rut her into the dirt. The other two leaned in, Sweetie now using a dildo made of magic to fuck Apple Blooms cunt in time with Dash's now frantic thrusting. With a fast, hard jab, she opened up Scootaloo's cervix, pausing to enjoy the grip around her, and being now hilt deep. She began to thrust again, deep and slow, her cock throbbing in the tight, warm depths surrounding it.

Scootaloo rolled her hips up, meeting each thrust with enthusiasm, her eyes rolling back in her head as she moaned, wings fluttering in the dirt. The pain of her cervix opening drowned below the ocean of her pleasure. Apple Bloom suddenly sat on her face, Scoots immediately tonguing her cunt expertly to get Apple Bloom creaming within seconds. Dash watched with approval-she had always suspected the trio were a poly triad. She was going to enjoy this dynamic, especially once she convinced their sisters to get in on it.

Apple Bloom rolled off Scootaloo's face like a puppet with its strings cut, her orgasm in the presence of Dash's obscene dildo brought to new heights. She twitched now and then, grinning lazily. Sweetie looked a bit surprised at the strength of Bloom's orgasm and how satisfied she appeared. Something told her it was Dash-engaging in sex acts with Dash's partner alone could make you cum your brains out. The influence of the dildo stopped her from realising there was no way she could know this, no way it was possible. Like her sister and her friends before her, she could only feel lust and desire, caring only to sate the fire between her legs.

Scootaloo jolted Sweetie out of her contemplation of her own pussy, with a cry of pleasure, over and over, Dash grunting as she came with her, each jolt of magic seed, each massive load, making Scoots cum harder than the last. Sweetie watched in fascination-this seemed so much stronger than Apple Blooms had. Scoots eyes had rolled back in her head as her back legs trembled with both the force of orgasm and force of Dash's cum packing thrusts. Scootaloo's womb swelled, stretching to accommodate the cum pouring in like a fire hose. Sweetie walked up to them, gently rubbing a loving hoof over the bulging tum. "Wow...you're so full! Look at all this, you might have triplets!" She enthused, kissing it gently.

Dash finally pulled out, some cum spurting out after her cock unplugged the well fucked pussy and covered it outside as it did inside. She smiled, "Might be a whole herd," she joked, "Gonna have my own town after this!" She turned her full attention to the other two. She decided on Sweetie Belle, since Apple Bloom was still recovering from her orgasm.

Sweetie saw the look in Dash's eyes and understood. She pranced excitedly in place, before turning around, flicking her curly tail over her back. She was wet and matted with her juices along her thighs, both from watching and Bloom's gentle hoof. Dash took a few moments to nuzzle her-like Rarity, there was a hint of perfume, even down there. Dash personally thought it was a useless thing to do, but couldn't deny it helped them stand out a bit more. Satisfied, she mounted the younger unicorn, cock sliding between the white pussy lips, and leaned forward to teasingly lick the horn jutting up from Sweetie's curls.

Sweetie moaned, the gentle ministrations feeling good on her sensitive horn. Dash lapped and suckled on it like one might a nipple or cock, careful not to overdo it or accidentally harm the sensitive magic horn. Dash grinned, giving it one final long lick, and slowly began to ease into her. She felt a bit tighter than Scoots-maybe just a bit more tense still. Dash pulled back and let her cock rub against the folds and clit, enjoying how moist she was. It dripped down her cock length to her sheath, and dripped off her swinging balls to the dirt road. Soon, Sweetie began to roll her hips in response, and when Dash went to enter again, she slipped right in.

Sweetie squeezed down on it, moaning, Dash opening her up gentle and slow. She'd prefer to really fuck, but she needed Sweetie nice and wet first-she was very tight inside, and didn't seem able to plan her squeezing down or movements. Dash guessed a strap on wasn't a usual play toy for the poly triad. She grinned, hooking her forelegs around Sweetie's waist, pulling her in close. It hardly mattered now-like her friends, these three now had the real thing, throbbing for them and ready to unleash a weather factory's worth of cum.

Dash nuzzled Sweetie's curls, murmuring encouragement and praise to her. Scoots had recovered, in that she could sort of roll her body over, clenching to keep the cum in-regardless, it left a white trail still. Apple Bloom came back to her senses when Scootaloo began licking the juice out of Bloom's pussy directly. Bloom blinked, looking around, spotting Dash and Sweetie fucking, and Bloom put her hooves on Scoot's head, her hips rolling with each lick of talented tongue into her foal hole.

Dash grinned at Bloom's interested gaze, gently pulling Sweetie's hair back by her curls, making sure Sweetie had to let out each and every moan or gasp. Bloom's hips rolled more firmly, almost face fucking herself on Scoot's muzzle, who certainly didn't seem to mind. Bloom wrapped her legs around her partner's head, resting her legs on the other's back. The gentle tickling from Scoot's wing boner felt quite nice with everything else going on too.

Dash began pulling Sweetie back by the hold on her hips, humping steadily harder, their bodies smacking lewdly together each time. Sweetie cried out, her back arched, hind legs quivering so violently only Dash's fore legs held her up. With a bright pink pulse from under Dash's tail, Sweeties orgasm hit, and hit hard. Her eyes rolled back, trembling from nose to tail, Dash's thrusts into her becoming and sounding much sloppier. Dash licked her lips, a second pulse from under her tail setting off her second orgasm, and like her sister, Sweetie's unused womb began to swell with the load. Dash thrust again and again, packing it deeper and harder each time.

She pulled out with even more squishes, Sweetie's hind legs now supported by her magically bloated womb. She panted, falling asleep right there, in the middle of the dirt path, full of cum and stinking of sex. The other two didn't seem worried, most likely a usual occurrence when they fucked her. Scoots lived up to her name, carefully moving aside so Dash could get in position for Bloom.

Bloom looked up, eyes unfocused and glowing like her friends. "So, uh...mah sis did this too? It's okay f'r me too?" she asked nervously. "Ah thought we was keepin' it in the family?" she asked, wanting to make sure it was alright.

Dash nodded, "Yeah, I'm not stoppin' you girls fucking who you want, and this way there's more family to fuck!" she encouraged. Bloom's face went wide eyed with realisation. Dash was right! This was the best idea ever!

Bloom grabbed her hind legs, holding them apart and on either side of her head to show off her sopping wet slit, glistening in the sun. Dash watched approvingly. "Bit of a gymnast huh? That'll make this so much more fun," she walked over to Bloom, crouching a bit, putting her fore hooves on Bloom's still small teats. She rubbed them gently, deciding she liked them small at first-it'd really show the growth when the pregnancy hormones kicked in. She nuzzled Bloom's navel, and began pressing in. She went in much easier than the other two, grunting in surprise. "You have a habit of your brothers dick, huh?" she asked.

Bloom blushed, but nodded. Her cunt clamped down on the girl cock, and began massaging up and down the length. Oh yes, she was very used to actual cock. Dash grunted, her hooves still gently rubbing the soon to be motherly tits. She shivered, Bloom practically sucking the cum out of Dash's cock. Dash rolled her hips more firmly into the motion, tail hiked up to expose her glowing dildo filled cunt. Every time she thrust in, her cunt tightened too, the dildo making her feel full and stretching her out.

She also thought it felt...bigger. She dismissed the thought-not that it was fanciful, but that it was a good thing. Her harem got bigger, so did her dildo, and then so did her power. Her attraction, drawing mares to her willingly-as far as they knew. She wondered briefly if she could father an alicorn, before a familiar shiver began. She grinned down at Bloom. "I'm gonna blow my load soon-gonna drown those ovaries in my sperm."

Bloom nodded eagerly, doubling her efforts, but soon lost rhythm due to her own orgasm ripping through her. If she thought the one earlier was intense, it was nothing compared to the one she had with Dash's cock slamming into her cervix. She clung to Dash, moaning in ecstasy, Dash pushing past her cervix much easier than the others-she'd need to thank Big Mac soon-and came as soon as she popped inside, the force of her own seed shooting out making her cock pop not just back out of the womb, but out the pussy lips entirely, a final spurt of magic girl cream coating the cream stuffed apple treat in front of her.

Dash sighed, not in exhaustion but satisfaction. A job well done...and she was just getting started.

The Great and Powerful Afterdark Spectacular

After sending the Crusaders to the Friendship Castle, the unofficial base of Rainbow's harem, Rainbow herself went in search of more pussies to knock up and keep. She didn't currently have anyone in mind, deciding just to approach the next hot mare she saw. Flying above the town, she soon spotted Trixie's wagon and Starlight outside of it, seemingly waiting on her friend.

Rainbow grinned wide, her eyes flashing pink, and began to glide down to the wagon. She skidded to a stop in front of Starlight, turning a grin to her. As soon as their eyes locked, Starlight was immediately under her sway shown by the pinkish tint covering her eyes. She smiled at Rainbow, eyes unfocused, her pussy juicing itself up already.

"Oh, Rainbow Dash! It's great to see you, what do you need?" Starlight asked.

"Well, y'see, Trixie always seems to have a lot of fun with you on stage, and I thought maybe I'd ask if I could perform too?"

Trixie came trotting out of her wagon, pausing, eyes gaining the same pinkish sheen as everyone else. She blinked, before cocking her head. "You wish to be Trixie's extra assistant?"

"Nah, more like you two assist me. See, I wanna do a like, afterdark show. You know, more...adult. You can charge more for it too, Trix!"

The pair looked at each other, clearly considering it. They both nodded, and turned back to Rainbow. "The Great and Powerful Trixie accepts your offer to make her even more famous, Rainbow Dash!" Trixie said as she posed, before inviting them both in. "Come, tell us what magnificent show you have in mind!"

They entered, Rainbow chuckling as they imagined performing for the whole town, showing off her goods and inviting more ponies to be hers. She couldn't wait...

A good portion of Ponyville turned out for Trixie's Midnight AfterDark Spectacular, starring Rainbow Dash. It was sure to be one hell of a show if both Trixie and Dash collaborated, helped by Starlight's magic. No one wanted to miss it. The fact it was adult only and held in the middle of the night was a mysterious draw to the ponies too.

Trixie's wagon was in the middle of town, in front of the fountain, the stage set up and ready. It was bare, making ponies more curious about it. The only decoration was a banner declaring the shows name. They all sat in a semicircle around the stage, looking excited. No one paid attention to the odd mist swirling around their hooves, making cocks slide free and cunts juice up with as much excitement as the crowd.

Rainbow stepped through the curtain first, head held high, in socks on each leg. The ones on her hindlegs framed her pussy and sheath nicely, the rainbow pattern on them lit up by her artifact. She strutted around proudly, her wings erect and tail hiked up to everypony could see. The Artifact already worked it's magic, no one thinking it was odd to have a porno show in the middle of town, even if it was in the dead of night.

Trixie and Starlight joined her shortly after, letting her strut for a moment, wearing matching rainbow socks on all their legs. The pair also wore tall tail rings that held the tails up and showed off their privates at all times. They were both leaking down their legs, pussies wet and ready.

The pair turned, their backsides to the audience, glistening in the show lights. Rainbow strutted in between them, facing the crowd.

"Mares and gentlestallions, welcome! To the first ever Trixie's Midnight AfterDark Spectacular! A show I can guarantee you've never seen the likes of before!" Rainbow announced, the crowd stomping in applause.

"Tonight, you will see something brand new-Trixie as my assistant! Give a round for our gracious host," she joked, the crowd laughing and applauding again.

"Can everyone see my lovely assistants? Everyone can see how wet they are, how ready? Yes? Awesome. For our first act! Watch in amazement as my massive mare dick invades their foal holes!" she turned to the side, hoof up, her sheath on full display and her cock sliding out of it. The audience made oohing noises, some applauding at the show.

Rainbow mounted Trixie first, her fat cock rubbing against the magicians drooling wet hole. "Behold! As I impregnate my lovely assistant, live, on stage, for your clopping pleasure!" a few members were actually masturbating when they realized it was going to be a sex show. One or two were getting ready to mount another themselves.

Trixie and Rainbow spread wide, tails hiked, everything on display as Rainbow eased her cockhead against the throbbing, needy pussy. Trixie moaned, turning her head to make out with Starlight, adding a bit of lez to the show. Someone wolf whistled, and Starlight moved a hoof to her own genitals, parting her lips so the audience could see inside her slut hole while she rubbed her clit.

Rainbow popped inside Trixie's pussy, the crowd wide eyed and leaning in to watch. Trixie moaned, "Yes! Fuck me Rainbow Dash, impregnate the great Trixie! Knock up my powerful womb, right in front of a crowd!" she was drooling profusely down her hindlegs, apparently having had a voyeur fetish she'd been hiding.

"Damn right, you hot little tease, you love it when they can see my cock stretching you out, don't you? You want them to see the second you get knocked up!" Dash declared as she humped the magician, pussy juice churned up and spraying out around the penetration.

Trixie rolled her hips back onto the meat inside of her, panting in delight, Starlight now with her head on the ground, using both hooves to massage and hoof her own pussy. She watched her friends expression, enjoying it. Dash grinned, turning a bit, lifting Trixie's hind leg up into the air so the crowd got a good view of her pussy gobbling up Dash's girl cock. They could see every pop of her pussy lips over Dash's medial ring, every drop of moisture running down a vein.

Trixie rolled her hips back as best she could with one of her legs upright. The thrill of being watched, until she was impregnated no less! Kept her cunt gripping and rolling, massaging the welcome cock with each thrust. Everyone could see-see every thrust, every drip of pussy juice so they'd KNOW how much she loved this, what a nasty little slut she was, and the thoughts just made the puddle of precum and pussy juice grow around her hindleg still on the ground.

More than a few ponies were now mounting up or being mounted. Lyra and Bonbon were scissoring frantically in the front of the crowd, and the Cakes had stood on a bench so Mrs Cake could be mounted while they both had a good view of the action. Couples and strangers alike fell to the Artifact's general aura, all of them full of lust and no idea how to actually sate it. Those without or who couldn't find a partner did their best to sate themselves with a hoof, magic, or wing.

Rainbow grinned as she looked out over the crowd, her pink eyes glowing brightly even over the stage lights. She hooked her front legs under Trixie, letting go of her hind leg, and thrusting faster, Trixie's dirty talk now a random word salad of moans and encouragement. She tensed, moving her hips back, shivering in delight and effort as she raced to her own finish. She eyed the crowd, making eye contact with many of them.

"Yes! Watch me, everypony! Watch me be literally bred by this fine specimen, only the best cock for TrixIEEEEE!" She squealed, cumming hard, the front row of the crowd a splash zone. No one seemed to mind, many opening their mouths to taste and swallow it down or reaching a hoof out, using her squirt to lube themselves as they wanked.

"Here it cums! The climax of our first act, everypony!" Dash declared, holding Trixie's hips close to her, moaning as she spurted a large amount of foal batter into the fertile hole. She gave a few thrusts to pack it in, her own tainted cum splattering some ponies. Everypony that tasted it or put it on their genitals seemed to lose it, reaching Pinkie levels of random sluttery. Muzzles in pussies or assholes, suckling on dick or teat, it didn't matter. The show had become a massive orgy.

Dash pulled out, chuckling, Trixie collapsing to the stage floor. Her pussy was stretched wide open after their fucking, cum filling the space entirely and drooling down her legs. Starlight got to her hooves, picking up Trixie in her magic and moving her behind the curtain-Dash needed to be sure Trixie was pregnant with her foal before she got to slut around.

Once finished with her chore, Starlight trotted up to Dash at the front of the stage. "Everypony! If I may have your attention!" she called, everypony turning to look at her. Dash laid on her back, side to the audience. "Watch in amazement, as I make this massive cock vanish and reappear rapidly, right in front of your astonished eyes! You won't see an inch of this magnificent member, I guarantee it!"

The crowd cheered as she positioned her rear over the fat cock Rainbow held upright with her fore hooves. Starlight nestled her pussy against the tip, winking at the audience. "Here I cum!" she declared to laughter and delight.

She sat on the cock, the length quickly disappearing inside of her pussy. She shivered, cunt honey flowing freely around the deep penetration. She raised her hips, making it 'appear' before sitting down and 'disappearing' it again. She did it in quick succession, the crowd cheering her on. Rainbow grasped her hips, announcing, "Here's my surprise magic trick!" she grinned, raising her hips to meet Starlight's, and popped through her cervix to the pleasant warmth and grip of a currently unused womb. She fucked through it thoroughly, opening it wide.

Starlight cried out, and then moaned, rolling her hips to meet Rainbow's with each and every thrust. They met with wet smacks, splattering the audience even more. Starlight raised her tail, looping it around a foreleg, keeping it out of the way so they could see the penetration into her sloppy cunt. She wasn't into being watched like Trixie, but she had to admit she loved this.

Rainbow moved her hooves from Starlight's hips to her teats, pressing against them, feeling them up with a smile. They were very decent breasts, and Rainbow was very much looking forward to playing with them when they were heavy with milk for yet another of her foals. The thought had her gritting her teeth, rushing towards another orgasm. The Artifact ensured she could go as long or as often as she pleased, sending throbs of pleasure itself into her pussy-like if she was fucking herself like she was currently fucking Starlight.

Rainbow grasped Starlight tight, slamming her body down, and came in a rush of magical sperm, bloating Starlight's gut. Starlight trembled, the magic sperm in her womb making her hornier, wanting more cum. She didn't stop moving her hips, her pussy milking the fat cock inside her for every tiny spurt of semen. She only stopped-with a whine-when Dash herself pushed her off. Starlight grumbled, but trotted to the curtain, joining Trixie behind it, and the pair began to lick the cum out of each other.

Rainbow strutted back to the front of the stage. "This concludes the show part of the afterdark spectacular! If anyone wishes to meet my lovely assistants, you can join them behind the curtain in their cunt licking. As for me...I'll be taking applications for my harem all...night...long," she grinned, the Artifacts power enforcing her words. No one wanted to leave any more, each and every one regardless of gender or ability wanted her to breed them, feeling her warm cum surge up into their bodies. No one in town was immune, and after this town, no one in Equestria would be-and she had high aspirations.

Rainbow Pranks Royalty

Rainbow rose from the pile of sated bodies, stretching like a cat before gliding the short distance to the ground. The sun was midway through the sky, and Rainbow was very hungry. A side effect of the Artifact seemed to be ponies doing anything to earn her favor, she mused as she sat on a bench at the park, eating a burger and hay fries that had been given to her.

She glanced at the sun, thinking of a different kind, emblazoned on the most sought after flanks in Equestria. She mulled htis over-how to get to Celestia's hot booty? She finished her meal, deciding the path was obvious-she'd had Twilight, now she'd go for Cadance and Flurry, then Luna...and once she'd had all the alicorns aside from one...she'd go to Celestia. She nodded, pleased with that.

She leapt into the air, soaring to the Friendship Castle. She'd need a bit of back up at first, and why not? Orgies were hot as fuck. She slid into the castle on her hooves, enjoying the easy slide over the crystal floor. She strutted into the map room, where all her friends currently were. They were all happily comparing foal bumps. Twilight was currently in the lead, apparently with at least five foals.

"-wasn't sure if I'd have an alicorn like Cadance or not, but having a lot of foals in early life can be normal for alicorns, I asked Celestia about it. She sends congratulations to us all, by the way! I didn't tell her who the sire was though," Twilight giggled, "I figured we'd pull a prank on her for once."

Rainbow sat in her throne, "I think that's brilliant, Twi-in fact...why don't we prank ALL of the royals?" she suggested slyly. "Cadance is still looking to have an orgy, isn't she? Why don't we surprise her with one at the Crystal Palace?"

Twilight clapped her hooves, "That's a great idea, Rainbow! A prank, but also something she wants! No one will see it coming!" the girls all agreed, all of them so deep under the Artifacts influence they'd do anything Rainbow asked if she said it would get her off.

Twilight wrote a letter to Cadance, and soon, the plan was in motion-Twilight and the girls would visit them under the guise of seeing her family since she was pregnant. The girls coming along to, of course, give her support-just not the kind the Crystal Royals would expect.

The train pulled up to the station, Rainbow and her sluts happily getting off and heading right for the castle. Gleefully, Rainbow rubbed her hooves-the Royals wouldn't greet them right off, they had some things to attend to. Perfect, giving them all time to get to the Royals bedroom, and surprise them with an orgy!

Cadance and Shining Armor headed to their room, the girls having said they'd met them there. The pair just assumed they wanted somewhere private to talk, after all, rumors about Twilight being pregnant had reached even their kingdom. The pair bickered playfully over whether she was, and who the possible father might be. They opened the door, and stopped as if they'd hit a wall the shock was so intense.

The girls were all on the bed, engaged in a massive orgy. Rainbow had been soaking the air in her new sexual magic while doing so, the royals had no idea they were hers as soon as they walked in. It didn't help the air was also saturated with the smell of excited pregnant pony pussy.

All around the room, acts of lesbian sex happened. Applejack was hogtied, Rarity sitting on the floor in front of her so the workhorse could work her tongue in Rarity's drenched marehood. Fluttershy and Pinkie rubbed theirs together, Fluttershy making cute noises when their clits flicked together. Twilight was kneeling before Rainbow, worshiping the magicock with her mouth, sitting at an angle so her heavy belly was showing. Shining's cock reacted, sliding free of it's sheath, Cadance holding her hind legs together as excitement drooled down them. Rainbow smirked-this would be easy.

"Heya, guys! Just in time, come help spread the love!" she encouraged them, only a very faint part of Shining-remembering how Chrysalis' control felt-screamed something was wrong, but the magic and hormones increasing in his mind drowned it out entirely.

Cadance happily trotted over to Twilight, lifting the younger's haunches to get at her pregnant, slippery slit. Cadance's tail was flagged so high it rested on her back, pussy soaked in her own excitement. Shining looked around, trying to decide where to jump in. Pinkie waved him over excitedly, and when he trotted to her she bowled him over on his back, grinding on his chest while Fluttershy nosed his sheath, "Um...is it okay if I taste you, prince?"

He grinned over Pinkie's shoulder, nodding, and Fluttershy began to lap at his exposed cock. Meanwhile, Shining yanked Pinkie's plot over his face, tongue immediately deep in her snatch. She rolled her hips, front hooves balancing herself on his head. Shining was surprised how well Fluttershy was doing-by the looks of it she'd had her experience in friendship orgies. She deepthroated his admittedly impressive member easily, slurping and sucking enthusiastically.

Rainbow moved away from Twilight's front, allowing her to rest her upper half on the ground while her sister in law tongue bathed each and every inch of Twilight's cunt she could reach. Rainbow moved behind the crystal princess, touching a hoof to the soaked pink petals. "Damn, princess...you've got a hot little cunny, don'tcha?"

"I am the princess of love...in all its forms," Cadance smirked over her shoulder at the pegasus, taking a few moments away from her enthusiastic eating out. Twilight whined, rolling her pregnant hips, and Cadance got back to business, feeling up her sister in law's pregnant, milky teats. She leaned down enough to get a taste of that nerdy breast milk, before flicking her tail over her back, giving Rainbow a smouldering look.

Rainbow grinned-she'd seen that look enough to know what was wanted. She mounted the princess, who moaned at the touch. Rainbow's cock prodded at Cadance's flower, pressing in and opening its petals. "O-oh! S...slow! That...that's the thickest cock I've ever had!" she squealed, shivering in lustful delight.

Rainbow slid in, slowly, but without pause, filling the princess with her long cock. The dildo in her own pussy throbbed thickly, gaining even more power from the slow breaking of yet another alicorn. She moved back and forth, slowly, relishing the feeling of the clutching cunt.

Cadance whined, moving her hips back onto the corrupting cock, and Rainbow let her-the more Cadance did on her own, the easier it was to mold her mind, to convince her eventually bear a foal. Rainbow rested her front hooves between's Cadances wing boners, gently rubbing the tender, sensitive flesh. They shivered, feathers wiggling at the ends. Rainbow leaned down, running them through her teeth, grooming throughly as they fucked-but the gentleness, the thoroughness was far more akin to making love.

Twilight moved away so Cadance could focus on cock, strolling over to her brother, still tongue deep in pink pussy. She approached Fluttershy, gently nudging her. "I'm really sorry, Fluttershy, but can I have that cock please?"

"Oh, of course Twilight! Family should always get first dibs," she nodded, after letting the cock pop out of her mouth audibly.

"If you can lay in front of me, I'd also really like to taste that pregnant puss?"

"Oh, yes please!" Fluttershy lay on her back, legs spread wide, unable to see over her swollen pregnant tum. She rested her forelegs on her that same tum, smiling at the feel of it.

Twilight used her magic to prop her brother's cock up, stroking it to keep it hard as she did so-he was too immersed in Pinkie's pie to have heard their conversation about switching around. She giggled, enjoying the first prank they were to pull. She settled her fat cunt against the incestuous shaft, twitching her hips so she drooled down his shaft, soaking him to the balls in her own cunt sap.

She pressed against it until the head popped inside, moaning, sitting down, excitedly sliding all the way to the sheath. Shining let out a confused, if horny, mumble at the sound of his sister sighing in pleasure as a pussy slid down him. Pinkie just giggled as she remained on his face.

Twilight moved her hips, grinding, not moving up and down. She squeezed her cunt muscles, her brother's hips flexing upwards. Her wings shot out in a wing boner, and she put her weight on her forelegs so she could both smack hips with Shining and give Fluttershy a good licking. Her tongue traced her gentle friend's folds, humming pleasantly at the taste of motherly Fluttercunt.

She timed her thrusts on Shining's cock, so when she lifted her hips she pressed into Fluttershy's pussy, like some sort of erotic seesaw. Shining managed to get Pinkie off his face to see who was working his cock. "...Twily...? What are you..." His eyes were already glossed over with pink, deep in the thrall of the Artifact's power and pleasure. He didn't push her off, rather gripping her already widening hips and helping her bounce on his cock.

Cadance watched, interested, her cunt gripping and rippling randomly as it turned her on. Rainbow leaned over her, even the High Slut of Fuck susceptible to her new affects. "Looks nice, doesn't it? Shining stuffing his sister with that tasty cock...shame she's already pregnant. I wonder if he'd like the next go?"

Cadance came with a lustful wail, the mere thought of an incestuous breeding between her husband and his sister sending her into spasms of pleasure and desire. She exploded around the marecock stuffing her, soaking Rainbow and a good portion of the floor. Like her husband, her eyes coloured pink as her mind gave in entirely to the pleasure. Rainbow grinned, grinding into the alicunt. "What about you, princess...? Do you want a hot lil cuck baby in that hot lil womb?"

Cadance whimpered, writhing under her. "Yes! Oh, fuck, yes, I do! Please, fuel up my foal factory! Keep me pregnant! A raging slut like me needs to be kept with child, nothing's hotter than being bred!"

Rainbow couldn't help but agree-a raging slut always needed a firm hoof and a thick cock. She hooked her forelimbs around Cadance's waist, hips a blur as she made use of her speed. "Keep looking at them, Cadance-I like that you're all slippery for incest. It's gonna make it so much more satisfying to plant a baby in you, knowing one day you'll want me to make more with this one-!"

She grunted, the Artifact in her rewarding her massive cumshot with an advanced orgasm. She shuddered, pussy clenching randomly, sending bolts of pleasure through her. Cadance rolled her hips, milking each and every drop of cum out of the cock and into her hungry, cum sucking womb. Rainbow dismounted, rolling off and nearly falling. She sprawled on the floor, panting and grinning happily. She was brimming with power now-she was absolutely confidant she could take the Regal Sisters. In more ways than one, of course.

She was distracted by Twilight's howl of pleasure, creaming her brother's cock. She slammed down to the hilt, holding herself there, feeling his flare throb fat globs of cum right against her sealed cervix. Fluttershy was laying near comatose in a puddle of her own fluids, a hind leg trembling. Rainbow shook her head, smiling-but the thought that soon the whole world would be as Fluttershy was...

Pregnant. Horny and satisfied in measures. Worshipping her cock, her herd, as it grew...she grinned wider, the grin almost demonic. Well...that'd be cool as hell, wouldn't it?

Rainbow Pranks Royalty II

Luna woke up from dream walking, vaguely confused and very worried. All the dreams lately had either been about being bred by Rainbow-which was odd, as she was certain the pegasus was a born female-or having her foals, and both seemed to get the dreamer off just as much.

She checked the time- sunrise. She had time to talk to her sister about this, then. Multiple dreams of a single pony weren't rare, especially when it came to heroes or celebrities or even royalty. But this...the same kind of dream, of one single mare, in a way she shouldn't be biologically capable of. It stank of possible dark magic, mayhap a curse on poor Rainbow Dash somehow?

She got out of bed, foregoing her regalia, heading straight for the breakfast table. As she thought, her sister was already there, the sun going up as Luna lowered the moon. "Sister! I have urgent news, I fear someone is using dark magic on Rainbow Dash,"

Celestia looked up from eating, frowning. "That is bad...how did you come to this conclusion?"

"Many ponies are having dreams of her...but aside from the ponies with her, every dream is the same, and Rainbow Dash is not as she is in the real world."

"Worrying...no wonder Twilight sent me a letter asking to visit."

"Ah, good! We should still be careful, but whomever cast this hopefully won't be suspicious at her seeing us this way."

Celestia wrote a note, sending it to Twilight. "I invited them here at sunset so we both may deal with this problem. Now please, go get some rest." she smiled gently, and Luna trotted off to bed after a quick nuzzle.

Luna awoke to the sun still in the sky, confusing her. She touched it with her magic-it wasn't being held up, it simply hadn't been set. She pushed it down gently- it wasn't happy she wasn't her sister, but it did go down. Luna checked the time- an hour past sundown. Something was very, very wrong.

She galloped out of her room and was halfway down the hall before it hit her- no guards. So then where...? She slowed down, looking around the hallways as she trotted along. Her ears turned and twitched, catching faint noises in the distance. She began to blush as she got closer, realizing the noises were of ponies in the throes of passion...many of them...and judging by the sounds, all kinds of different pairs and even groups.

She slowed down, moving towards the throne room, gasping as she heard her own sister's voice! The villain had already gotten to her! She galloped as fast she could, throwing the door open, revealing...oh. Oh my.

Her sister was indeed there, laying on her stomach, tail flagged out of the way so Rainbow could plow her with a massive she-cock. Her faithful student was on her back in front of Celestia, legs spread, an obvious baby bump adorning her smaller frame. Celestia was, quite frankly, eye deep in her student's snatch, literally face fucking.

Around them ponies fornicated, most notably the other Elements and the Crystal royalty fucking the guards. Even Cadance sported a bump, smaller than the others, but there. She rode a solar guard's cock as her husband fucked that same guard up the ass, making out with his wife as he did so.

Fluttershy and Rarity were double teaming a lunar guard mare, Rarity rubbing her pussy against the guards, Fluttershy on her face and squeaking adorably. Luna couldn't believe it- her own guard! Everywhere she looked, debauchery and pregnancy. She stormed in, horseshoes thunking loudly on the masonry.

"ENOUGH! STOP THY DEBAUCHERY!" she bellowed, causing everyone to look at her, including Rainbow, who's eyes she met, still balls deep in Celestia. This was a mistake, as Rainbow's erotic power had grown- she had overpowered Celestia with her own lusts easily, and Luna would fall to her knees just as she had.

Luna's eyes drooped slightly, taking on the same pink sheen as Rainbow's other victims. Rainbow grinned. "Stop? You don''t want us to stop...you want to join us! Right, Princess? You want to come over here, and join us, you want to celebrate with getting pregnant too, right...?"

Luna began walking over, tail flagging. "Yes...I want to be gravid, I wish to have the milky teats of a beautiful, pregnant mare..." she admitted, spilling her own fetishes.

Rainbow grinned wider, "Awesome. Gimme a moment, gotta fuel up ya sis's foal factory first," she explained, Celestia wrapping her tail around Rainbow's hips and meeting her thrusts with her own rolling hips as they got back into it.

Luna sat next to Celestia's flank, removing her shoes to massage her currently flat teats and rub at her drenching pussy. Twilight came on Celestia's face, the elder princess lapping the girl cum up off her face, whinnying as Rainbow buried her girlcock to the hilt and came, filling her with gallons of cum, bloating out her royal womb and back washing out of her tight cunt.

Rainbow pulled out slowly, enjoying watching the stretch of Celestia's labia around her fat, oversized mare cock. It came free with a pop, still hard as a rock for her final princess pussy plundering. The dildo in her own cunt throbbed hard, excited. The magic it had collected each time it corrupted another mind was becoming staggering- this final conquest, one last alicorn, would give it enough power to become irremovable from Rainbow Dash, cementing both its and her power over Equestria.

Luna had lain her barrel on the floor, her haunches in the air with her tail flagged for the magical futa. Dash grinned, nuzzling Luna's cum trap, hooves doing an excited dance on the floor. She had to pull Luna down a bit to reach properly, but once she did she wasted no time in mounting her. Her thick cock slid into the alicorn's folds, spreading her wide. The cock seemed to be even bigger than before, visible through Luna's stomach. Dash took her time, slowly sliding in and out, relishing taking the final princess as the artifact lodged in her slowly absorbed the last of the magic it needed.

She leaned forward, biting down on the back of the princess' neck, hips moving more firmly as she rutted Luna right in front of her own throne. The artifact in Dash throbbed with each thrust, but instead of absorbing magic it was sending it out into Dash herself. With each thrust, she grew a little more. Her limbs lengthened, as her wings expanded and feathers molted just to be replaced by longer, better feathers in moments. Her thrusts increased, drumming a beat on Luna's ass.

Luna moaned, hips moving back to meet Dash's steadily more desperate and harsh thrusts. Her cunt contracted, muscles quivering around the girlcock. She whined as Dash pulled out, her muzzle now a little longer. She grinned, before slamming her cock into Luna's asshole without warning. Luna screamed, eyes rolling back as the artifact's magic still in her made her love it. Dash thrust, rutting, furiously, desperately, spurred on by the artifacts own need. With a mighty throb from the artifact lodge in her cunt, she moved her cock back to Luna's pussy and stuffed it in deep, just in time to unleash a torrent.

As she bred the last alicorn, the artifact let out its last vestiges of magic, disappearing in a burst of pink magic, absorbed into Dash. Now she stood eye to eye with Celestia, her powerful wings twice any alicorn's wingspan, her titanic cock now permanent.

Luna kept moving back, muscles moving to try to milk every last drop out of the cock taking her. Dash put a hoof on Luna's head, keeping her down as she pulled out, moving it back to her asshole. This time, she pushed in slowly, savoring every inch. She pushed in to the hilt, feeling the curve of Luna's guts as she did. Her cock had grown with her, now the length and width of an earth stallion's leg. Dash's other hoof caressed Luna's cutie mark, as she pulled out just as slowly. In and out, celebrating her victory.

Pink magic wafted from her eyes like mist, as she ordered Twilight over. Lifting her tail, she pushed the book worm between her thighs, and sighed as Twilight began licking her. From cunt to ass, she licked and thrust her tongue in Dash's holes in time with her thrusts into Luna. Dash wrapped her tail around Twilight's head to keep her snout deep in Dash's cunt, lapping at her walls, using her magic to tweak Dash's clit.

Dash began thrusting harder, grunting, one hoof grinding down on Luna's head. "Whaddaya say, Luna? Celestia? Should I be in charge? Should I be the one to rut your pregnant, needy holes?"

"Yes!" Luna screamed almost immediately. "You should! Oh fuck, this is what I am really for! For you to dump your hot cum in, to use me! You should rule!"

Celestia was more composed, but agreed. "Yes, obviously we should have been rutting our little ponies long before this. We've been remiss in our duties- please, Rainbow Dash, take the thrones and show us how to truly rule, with an iron cock."

Dash grinned, chuckling. She was now the Avatar of Lust, and every hole in Equestria belonged to her. Even the princesses agreed. Every hole that existed was hers, and literally no one could ever deny her. Rather, they would all beg her to grace them with her cock- and she could hardly deny them, could she?
