A Thug and a Buttery Mare
Author's Note
This is an RP I have done with my friend and more might follow in the future. My friend is very talented and the best parts of this RP will obviously be her writing. 
Obviously as this is porn, characters will be out-of-character so to say. My friend wanted to give that warning, though I think it is fine either way. I simply hope you will all enjoy this read! 
A Thug and a Buttery Mare
Fluttershy hummed to herself, as she was looking through her photo album. The young mare lived all by herself in her cottage, as always, but today was one of the rare times she was truly alone. Angel and most of her pets were on a "special vacation", sponsored by some friendly business-stallion she helped out one time. Sure, it had been a bit weird it was only her pets, but Fluttershy didn't mind some alone time.
"Oh my...that dress is so skimpy, Twilight...", she mumbled to herself, as she looked at a picture of the last Gala, where Twilight had worn a very form-fitting cocktail dress which had been backless almost down to her butt and with such long cuts to the sides that it showed even her naked hips.
Way too risky for Fluttershy's tastes, who preferred more demure outfits. Granted, that was a tall order given her body. Long, shapely legs and a plush, heart-shaped butt made even the baggiest of pants draw the eyes of any stallion, for some reason. Her wasp-like hips that then rose up to accentuate her perfectly shaped E-cup boobs gave her an hourglass figure that models would turn green over. And she should know, she had been a model once!
Still, Fluttershy tugged at her sweater and sighed. She had asked something simple from Rarity and her friend had responded by giving her a piece that not only hugged her curves but also left her shoulder naked. And she added a blue mini-skirt, which didn't even manage to cover Fluttershy's butt completely. Still, Fluttershy couldn't just say no to it.
Or all the other rather lewd outfits her friends had been giving her over the years. By now, the pegasus had literally no clothes left that she felt truly comfortable wearing or wouldn't call "slutty". Even Applejack, who had always been concerned about manners, had joined in and spent most of her time either flirting with strangers or getting paid for it.
Fluttershy shuddered a bit, as she turned the page and looked at a picture of her and her orange friend hugging the sides of the club owner and notorious sleazebag, Hard Rod. She looked visibly uncomfortable with the big stallion having a hand on her butt, but Applejack practically dry-humped him in her tight bodycon, grinning lewdly into the camera. Fluttershy had excused herself shortly afterward during that night, but not quick enough to miss Applejack offering Hard Rod a "discount".
Sighing, she closed the photo album and stretched her arms. Rising up she put the album back on the shelf and looked at the next one. This one likely had even more lewd and risque pictures in it, practically everything recent, she realized. "I wonder why...surely, it’s not just all lewd stuff," she mumbled to herself. Sure, her friends had become more open about their private life and embraced their sexuality in a way Fluttershy wasn't always comfortable with. But that didn't mean they were all sluts, spending their days seducing stallions, sucking cocks, and debasing themselves for the pleasure of strong, virile studs that saw them as nothing else but sexual objects, reducing them to a state of property and insulting their reputations as heroines for the sake of addictive plea--
Fluttershy shook her head and took a deep breath. She just realized her cheeks were flushed. "Oh my...I think I need to make some tea and calm down," she mused and headed for the kitchen. "If nothing else, I can always go upstairs and work out some tension with Mr. Big Black…"
A bit silly to give her dildo a nickname, admittedly. But only Rainbow knew about it and it was better to relieve some pent-up frustration, rather than having to date some scary stallion. Hm… Maybe Rainbow Dash would be willing for some lovey-dovey, adult sleepover too? Sure, she had switched recently and said that "all dykes need some dicking" as she had gotten, but Fluttershy was sure her best friend would still be up for some lesbian love if she asked for it.
With idle thoughts like that, she began to make tea...
The buttery mare was lost in her own little world. Enough so, that she didn't even notice the thug picking her lock and pushing the door slowly open. He went in silently and pushed the door mostly closed behind himself, being careful to not make a single noise.
He was tall, with black skin and a white mane, as well as a horn. A unicorn, but a very muscular one with broad shoulders, a trained chest, and an eight-pack. His black jeans were tight on his form, showing off a massive outline that no doubt could easily keep up with the buttery mare's most cherished toy. He wore no top, showing off his attractive body as he snuck into the kitchen where the mare was still standing at the stove, unsuspecting.
But not for long.
The big stud overshadowed her a mere moment later, just as she was about to put on the kettle. His large hands pulled down her sweatshirt and any bra she might have worn to pop those massive jugs out as he pressed into her back.
"Best don't try to run. This is a robbery. And one in which I will plunder your holes, you hear?" he growled dominantly, his large bulge humping against her skirt-clad ass.
Fluttershy squeaked in shock and nearly dropped her tea set as she was grabbed from behind. A burglar! Of all things now and here? Sure, Ponyville had gotten a bit more unsafe with all the new nightclubs and sketchy business owners. Not to mention incidents like last week where Roseluck had been gangraped by a bunch of thugs for several hours...
But for somepony to be so bold to break into her cottage, which was outside the city and with little to no neighbors or guards patrolling nearby--okay, maybe she shouldn't have been that surprised...
"W-What d-do you want, sir?" she stammered, trying to keep herself from having a panic attack. Oh gosh, she could feel his bulge pressing against her back! She wasn't a small mare, but even so, he was easily a head taller than her and his grip was like steel. She could do nothing but whimper, as he stripped off her sweater and skirt with ease until she stood there only in her pink thong, which barely covered her freshly shaved and puffy pussy.
"Please...t-there is no need to be rough. M-Maybe we could talk first and...and..."
"Talk? Only if your mouth is on my dick, cunt. I didn't come here to hear you blabbering, but to hear you squeal," he told her without hesitation or reservation. He was going to fuck her. The confidence and certainty he said it with made it sound like a fact as he pulled on her left nipple with his hand, while the other pulled down her thong. "Bet you bitch are nice and wet already. Not even wearing a bra too, as if you were expecting it," he told her, hot breath hitting her sensitive ear.
“T-That is because it is hard to f-find anything in my size!” she protested against that notion, not wanting to seem like a slutty girl.
His hand then went to his zipper, ignoring her words and as soon as he opened it, the large black cock was on her back, a real black monster. Ironic that she was about to shove a black dildo up her twat when she now had the real thing right here with her, only better and bigger.
"Big and black. I heard from that rainbow twat that you have such a toy and that mine is so much better than any fake."
"W-Who are you...?" stammered Fluttershy. A surprised squeak escaped her lips as she felt his hot shaft slap against her naked back. Gosh, it felt huge, reaching up to her shoulder blades, at least! She had seen a lot of cocks and a lot of pretty big ones already. Shining Armor, Big Macintosh, Blueblood...
This criminal surely was just as big. One of those muscled "alphas" that were moving into Ponyville more and more. Before stallions like Big Mac were a rarity and most mares had been in homosexual relationships. But now, Fluttershy had not seen a single day go by without a new, beefy, scary stud moving into town.
And now one of these studs was in her own home, about to rape her!
Worst of all, she knew she was getting sopping wet. The stallion stopped groping her lewd boobs and reached down. She heard him grunt approvingly, as he pulled his fingers back and stared at the sticky strands of sweet juices.
“A friend. Like I said, I know that prismatic whore,” he answered very vaguely.
"Y-You know Rainbow Dash...? W-Wait, p-please...i-if you hurt me...I will scream and...and..." Fluttershy trailed off. They both knew that calling the guards wouldn't work.
Trying to ignore her loudly beating heart and her body visibly anticipating the rough, intense rape, Fluttershy opened her mouth to argue. Then the fat, veiny, throbbing, black shaft slid down her back and was thrusted between her legs. Squished between her thighs, the stallion rubbed it against her snatch, teasing it.
The legalus looked down, mouth open, and stared in shock and awe at the beast between her legs. It was bigger than Soarin’s and almost as thick as Prince Blueblood! When this thing entered her, she would...she would…
"Please...b-be gentle..." she whispered.
The stud grinned at that. She had finally accepted her fate as was only proper for a mare. He aimed the tip at her moist tunnel, licking her cheek lewdly as his hands sunk into her tits again.
"No," he simply stated, making her body go stiff, before a moment later a powerful thrust made her feet lift off the ground. She jumped up from the force of it as that shaft instantly had pierced into her womb and then as she came down due to gravity. Yet, it still kept her up in the air, her wings twitching uselessly against his back as he gyrated her hips into him causing her to bounce on him like a mere doll. A sex toy.
An apt comparison, considering that it’s exactly the way he saw her as that large medial ring slammed in time and time again, scraping against her sensitive walls as the cock head punched the end of her womb without mercy. A true brutal rape and one that the shy mare wouldn't soon forget.
Granted, it was hard to rape mares these days. Even the most stubborn ones had trouble not cumming their brains out when pounded by a real cock and the law made it clear that once a mare came, it was no longer rape, but consensual. And given that the main advocates for that law had been a mare that had formerly been raped...
Fluttershy came immediately. As the thug slammed his dick into her pliable, soft pussy, she threw her head back and squealed loudly as a climax rocked her body from head to toe. She never stood a chance as her sexy, sensitive body was surrendering to its natural instincts.
Leaning onto her kitchen desk, Fluttershy had trouble standing upright and quickly began to moan loudly as she was rocked from behind by the strong stallion. His hips slapped against her, making her juicy ass jiggle and it didn't take long for her skin to shine oily with sweat.
"O-Oh...ah ahn ahn...s-so big...i-it's too big...." she tried to protest, but her words didn't match the juices that flowed down her legs and the ever-louder moans escaping her pretty lips.
"Really now? Too big? You slut already came and are close to doing so again even though I just started. You know what this means too, right? You can't call the guards on me anymore. This is consensual sex now because you whore squirted like a needy skank. I can do whatever I want now," he stated, one hand leaving a tit to grip her head and turn it to the side.
The stallion then captured her lips, shoving his tongue inside her mouth and wrestling with her own. He dominated it as his hips smacked into her by then wet ass. A wetness she all offered up herself as she couldn't hold her natural instincts back.
His hot precum was provided in large volume too and it helped to make her even more sloppy as well as to heat her up further. An alpha’s juices, after all, were like an aphrodisiac drug to mares while also causing their bodies to produce eggs to be impregnated.
Fluttershy was helpless. She could do nothing but let him violate her. Take her. Ruin her. Have his giant shaft batter her insides into the shape of his cock and rape her until even thinking was impossible.
A second orgasm went down her spine and made the sexy mare moan into her assailant's mouth. She closed her eyes and could do little but press her back against the tall stallion's chest while his free hand sunk into her large breast.
This was so wrong and yet it felt so good...
He used this moment to move, leaving the kitchen behind and carrying his quarry into her bedroom. With how willing she had gotten, he figured it was time to amp things up a notch and make her beg.
So as soon as his powerful steps had carried her up into her simple room with a comfy bed, he gripped her waist and pulled her off his member before throwing her on it, back first, breaking the kiss.
His hand held his dick as he walked up to her, her legs dangling off the bed. He slapped it a few times on her horny cunt with a victorious grin.
"Beg. Beg me to breed you or I will walk out of your home right this instant, leaving you to deal with this dripping mess yourself."
An offer, but also one clearly meant to demean her. He could leave, like she wanted at the start, though it was obvious she wouldn't want that anymore. This meant however, she had to plead with her burglar to fuck her and put a pair of fillies inside of her.
Fluttershy shuddered. Her body was weak and refused to listen to her. Her skin was on fire and her knees so weak. She was sure she couldn't run away if she wanted to, and wanting was exactly the problem.
She felt...empty. As soon as her rapist had pulled out, she could feel herself craving his embrace and his huge shaft filling her snatch, despite herself. She wanted it. She needed it. It wasn't enough, yet. There was more pleasure beckoning and the thought of ending it now was unbearable.
So, she slowly spread her legs and with tears in her eyes and a desperate, horny smile looked at the black stallion in front of her. "P-P-Please...please, breed me. I-I need it. I-I want to be a slut!" she stammered.
That was all he wanted to hear as he leaned down, his face getting close to hers with a triumphant grin. "I will be your Mr. Big Black now," he told her, practically telling her she won't need that toy anymore and that he planned for this to not be a one-time thing either.
And then he penetrated her again, his strong chest pressed down into her large tits as he fucked her into a mating press. "Wrap your legs around me, cunt," he ordered, groaning as he was punching the entirety of his cock inside of her, fucking her like a rabbit with rapid fast thrusts.
Time and again he invaded her womb which seemed to rejoice at the intruder as there was already a pair of twin eggs transported right into it. Eggs he fucked right against the walls of her cervix, showing the unborn sluts what will await them in life, practically imprinting it on them as well as on the whorish mother.
The pleasure was overwhelming.
Loud cries of delight echoed to the street outside as Fluttershy felt wave, after wave, after wave rush over her and turn her brain into mush. The orgasms were now coming one after the other, every thrust setting off stars before her eyes. Her face melted into a dumb smile and her tongue lolled out as any restraint was gone.
"Yes! Yes! Harder! I'm turning slutty. I'm turning sluttyyyyyyyyy!!!" she squealed, as she went through her strongest climax yet.
Her spine arched and her legs hooked together behind the stallion's waist. Her fingers dug into his broad back. Fluttershy's eyes rolled up into her head and any thought or fear was replaced by a fat, black cock.
Then she felt her rapist and lover grunt and his thrusts stop. His balls contracted and with a practiced motion, he hilted inside of her and began to cum. White, hot, thick liquid was pumped into her womb and filled it up in a heartbeat, drowning her egg. Yet, he still continued to cum and as there was no room, it began to spray out of her stuffed snatch and splattered onto her bed and floor.
The black unicorn slowly pulled out of her and sighed. His jizz-stained cock dipped a bit but was far from flaccid and one could hear his balls already churning with the next batter. Fluttershy was lying in her bed, her hair a sweaty mess and her skin glinting oily in the sunlight from the window. Her face was a drooling expression of bliss.
"Alright...bagged myself an Element,” grunted the stallion. "Dash certainly wasn’t wrong, you are proper eye candy." He jerked his pole until it was once again rock-hard. "But we aren't done yet, slut. Not by a long shot."
The corner of Fluttershy’s mouth twitched upwards as if her dumbed-down mind could still understand the meaning of those words. Her legs spread a bit farther as she welcomed him, welcomed the pleasure that was messing with her mind and no doubt would turn her into a needy nymphomaniac whore.
Rainbow Dash whistled to herself as she touched down near Fluttershy’s cottage. The former athlete turned stripper pulled out her phone and checked it. Countless messages to her foalhood friend and yet no reply.
"Weird..." Dash clicked her tongue and stuffed her phone back between her fat DD-Cup boobs. She invested a lot of money into them by request of Thunderlane as well as getting her ass pumped to nice dimensions. Sure, for flying it had been better to be aerodynamic and slim, but since she quit the Wonderbolts she didn't need that anymore. And her new curves got her a lot more attention from studs around her.
Dash cupped her new bust and grinned as she jiggled them. Fat, juicy, and sensitive as fuck. So fucking worth it, especially after seeing the shocked faces of Spitfire, Fleetfoot, and Surprise when she showed up with her new rack and slutted it up with fans backstage. After all, she saved Equestria like twenty times, so why not enjoy her fame and money for once?
Not fair that they kicked her out. At least Hard Rod had offered her a job at his strip club and if she was honest, Dash liked that a whole lot more now. She even got a taste for cock, after some practice!
Tugging at her black sports bra and matching spats, making sure all was in the right place and her bust was looking like it almost spilled out, Dash opened the garden gate and walked up to the door.
She would have been here sooner but Thunderlane had wanted a blowjob and it escalated after that. "Gotta thank Scoots later for tagging me out," mumbled Dash and chuckled as she remembered her adopted sister’s little, shocked face as she was left in the hands of a horny Thunderlane, "volunteered" by Rainbow Dash.
Eh, the little chicken had it coming anyway, being such a jailbait. And Dash was sure that after a few rapes, she would learn to like it. She did too, after all.
As she raised her hand to knock, she noticed the door to Fluttershy's cottage was slightly ajar. Raising an eyebrow, Dash slowly pushed it open and stepped in.
As she walked into the cottage, she heard a loud, squelching sound from the living room. Turning in that direction, Dash opened the door and stepped into the room, and saw...
…Fluttershy on her knees, covered in cum-splatters from head to toe.
Her friend’s lips were obsessively kissing and worshiping the fat, black cock of a towering stud of a stallion. The black-skinned unicorn lazily rifled through some cash on the living room desk, cash which clearly belonged to Fluttershy, and pocketed it.
He then looked up, seeing Rainbow standing in the doorway. "Ah, hey Dash. Took you long enough."
Dash opened her mouth, made a threatening step forward...
And then grinned lewdly, pulling out her phone from her cleavage. "Sorry, Obsidian. Missed the first six messages you sent me," she apologized and chuckled. She walked over to her old "friend" from foalhood, who had beaten up her cocky filly self several times in the past with swinging hips, and squatted down to join Fluttershy in licking his hard rod.
"Looks like you two had some fun?" she joked, looking at Fluttershy.
The pegasus's eyes were glazed over from lust and she smiled back at Dash just as lewdly, any semblance of innocence and shame raped out of her mind. Fluttershy had been dragged down to her friend's level and she loved it.
"Yes. I'm his bitch now, you know?"
Dash grinned back. "Awesome. Told ya, you're just a dumb slut like I am."
"Less talking, more sucking, whores. I want my cock clean, while I watch TV." Both mares giggled and went to work.
There was nothing more that needed to be said as both of them were fucked for the rest of the day. Neither one got a single moment of rest until they passed out in the evening in a puddle of cum with happy drooling smiles on their lips
