Bad Science-Control Group

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.
