Dirty Little Secrets

Fluttershy's cheek's turned bright red as she heard that all to familiar voice coming from the front of Rarity's boutique. There was a growing heat in her loins as thoughts started to race through her mind. Her fantasy session was ended by the sound of approaching hoof-steps back into the kitchen.

"Now, I don't believe I need to introduce our guest Fluttershy, after all I am quite sure you are familiar with him." Rarity said with a light smirk creeping across her lips. Walking in just behind the elegant Unicorn was a pony that Fluttershy did indeed know quite well. The two of them had gotten rather close over the past couple of months. Every Sunday they would meet in the park for a picnic. It had taken a few weeks but, Big Mac finally opened up and started to talk to her. Now he stood here before her, his cheeks as dark as they had ever been, hands held behind his back. "Now now, I won't have any of that from you Big Mac...say hello to the lady." Rarity commanded with a rather dominant tone in her voice. Fluttershy gave Rarity a quick glance, never hearing that kind of tone from her before. Big Mac's eyes widened as he dropped to one knee and bowed to Fluttershy.

"Howdy there Miss Fluttershy, I am glad ta be of service." Once again Fluttershy double-took and looked down at Big Mac. She had never seen him act like that, or break from his shyness so quickly. She glanced back to Rarity who simple gave a nod of approval.

"Good-boy Big Mac, you may stand up now" Her voice still held that commanding tone, but was now laced with confident sexuality.

"Y-yes Mistress Rarity" The large farm-horse responded as he rose back to his feet. Fluttershy's jaw dropped at the exchange between the two of them. She had heard of this kind of thing, well read about it anyway. It was something she always tried to look up, but then got scared away from.

"U-uhhm...R-rarity?...is Big Mac here..y..your.." Her words stuttered out of her lips.

"Pet? why of course he is dear, and before you start wondering, he actually came to me." She spoke with that same confident and sexual voice as she walked in front of him. "It was a rather pleasant surprise to find this big boy on my doorstep asking me for my help. I will admit at first I thought he just wished for social lessons and training...but when he explained to me that he wished to be a pet, someone who serves, and more importantly...OBEYS...well I couldn't resist." She chuckled reaching up to gently caress his chin. "Oh and don't worry, I don't use magic like some of those other dom's out there. This big lug is more then happy to do anything I say, well within our limits...isn't that right big boy." Her words caused the stallions cheeks to flush as he glanced down to her, his eyes filled with devotion.

"Yes Mistress, I serve you with joy" His words held a strength and confidence that Fluttershy had never heard before. This was exciting, this was sexy...this was...alluring. Fluttershy knew this was another piece to the ever growing puzzle that was her sexuality...though she didn't know where it fit. Thoughts of being forced to her knees to serve a Master or Mistress filled her with arousal. . . On the other hand being able to command respect, obedience, and express herself without being judged. As before, her thoughts were derailed by a loud thump from the real world. Once she shook the images out of her head, she was meat with a fully naked red stallion in front of her. Her thighs snapped together as she fell to the ground with a gasp.

"Ohh dear...Big Mac, be a dear and 'gently' scoop her up and bring her to our play-room? Also if you could lock the door, I would be ever so grateful darling." She whispered before placing a kiss upon his cheek.

Slowly Fluttershy opened her eyes, her mind still racing with her last thoughts. "O..ow...what happened?" she inquired as she rubbed the back of her head. Once her eyes got adjusted to the light, she saw Big Mac kneeling next to her. His eyes held a concerning look which melted away once he saw she was okay. "O-oh hello there Big Mac...where did Rairty go?"

"I am still here darling, just finishing up getting ready" her voice called out from behind a screen. "I have informed Big Mac as to your desires, and he is more then happy to help you with it. As I said earlier he does have a rather healthy diet, and I would recommend NONE other to begin with them him. He is the first I ever consumed, and by far the best! I will not have you swallowing down anything but the best."

Fluttershy blinked a few times in disbelief upon hearing her friend speak so casually of eating shit. Never in her life would she EVER have believed Rarity to be so involved with such a messy, nasty, gross fetish. Her eyes shifted over to Big Mac as a small smile crept over her muzzle. "Heh...I guess this is just something else we have in common...isn't it?" she asked shyly.

"Eeeeyup" Big Mac responded, matching her smile with his own. "Ah honestly had no idea it was you in those videos. H-heck seeing you make those video's is kinda what got me to serv'in Miss Rarity. A-ah had tried once before to uh...engage in some scat-play with another." He rubbed the back of his head with a chuckle. "Ah didn't quite know how ta do it and ah ended up splattering all over her face." The stallion sighed as he lowered his head. "G-good thing she could laugh about it, otherwise ah don't think ah'd ever try it again...much less anything else."

"We also have learned to not eat five bowls of veggie chili the day before haven't we?" Rarity called out from behind the screen. Big Mac blushed and nodded.

"Still don't know how Pinkie was able to wash that all out of her hair so quickly..." Mac said with a somewhat confused look.

"Darling you should know by now that our friend Pinkie is a unique one to say the least. Truly there is no other pony that can actually ...defecate actual brownie batter. Hmmm...I am still convinced she is actually a unicorn" Rarity commented as she walked out from behind the screen. She wore a gorgeous purple and black corset that pushed her already perfect breasts up. She also had on a pair of matching stockings and boots, all made from the finest of fabric. "What do you think my dear? is it not stunning?" Rarity smiled as she posed. Her face brimming with confident sexual energy. "If I had known outfits like this had a market, I would have opened my 'alternate' boutiques much much earlier."

Fluttershy could not help but stare at her with amorous eyes. She was gorgeous, her body was the definition of sexy that also commanded obedience. "Y-you really have outdone yourself this time Rarity...e-even I feel a bit w-weak looking at you." Her words causing a blush to come oer her cheeks.

"Well that IS the point darling, hmmmm, poor Big Mac here ruined one of my finest thongs when he first saw this outfit. I have learned since then to make anything for him out of much stronger material." Rarity chuckled with a wink over to Big Mac, who turned his face away with a blush. Fluttershy quickly glanced down to see the most elegant lace and silk thong on the massive stallion. His bulge was perfectly held and cradled in the fabric. "Aside from being quite the shit-stallion, my pet has quite the affinity for womens clothing. . .Now, I believe we are all here for a reason are we not? Fluttershy my dear, I hope you are still interested in your first meal...as it were." As she spoke, a riding crop floated up next to her. "Ohh don't worry, this isn't for you, well unless you beg me for it." She said as she cracked it in the air.

"Y-yes I am, truly and honestly, I-I want to be a dirty, filthy shit eating little mare!...O-oh!!!" she gasped and covered her mouth. "I'm sorry.." she said with a sigh. "I am such a naughty pony."

Rarity chuckled as she walked over to a Chez lounge that looked identical to the one Fluttershy found herself in. That crop floating over to the stallions ass before giving it a firm swat. "Stand up now..." she commanded with a bite of her lip. "Now I must admit this is the first time I have watched my pet feed another, and I simply CANNOT deny how arousing this is. I hope you do not mind me getting off to this" Rarity called out with a soft moan as a rather sizable dildo floated over to her. "Ohh and please remind me to have one of these custom for you...they are simply marvelous! Sized perfectly for ones nethers, but just big enough to drive you craaaazy." With a bite of her lip she began to push that toy inside of her, letting out a loud gasp as the flare popped inside of her. "Nfff...my my...that flare gets me every time." She remarked while getting settled. "Mmmm now Fluttershy...while I do not use my magic to force ones will, I do use it to help. Unless for some reason you are a rather gifted little shit eater that is, which would be quite a lovely discovery. Big Mac...straddle please!" As she spoke, that crop of hers smacked across his ass with a loud *thwack!* He clenched his fist, and bit his lip to keep himself under control.

"Yes Mistress..." he moaned out. The large red stallion carefully swung one of those toned workers legs over Fluttershy before setting it down. That massive, rather curvaceous rump hovering in front of Fluttershy. The yellow mare gasped at the sight, her heart starting to race as she realized it was actually going to happen. She lifted her nose and took a deep whiff. She quickly pulled away, letting out a few coughs.

"W-wheew..t-that ...that is...I.." she moaned and pushed her nose right under Big Macs tailhole, wedging her nose in between his cheeks. There was a loud grunt as Mac found her nose push right against his tailhole. That girthy length of his shooting out to full mast.

"My my...it does seem you are quite the filthy mare, though having smelled that for myself...I am rather jealous. Now...as I said earlier, I am going to use my magic to...encourage you, shall we say." She said with a chuckle. "Now please relax..." Fluttrshy nodded and let herself relax and go limp. Once she did, Rarity began to float her clothes off of her, leaving the yellow mare naked and exposed. "There is a chance that this will...oh who am I kidding, this is your first time eating...it is GOING to be simply filthy. One more time...relax for me" She whispered. Fluttershy bit her lip as she looked over to Rarity, wondering all of what she was planning. Her wings shot out as a loud gasp escaped her lips. "Eaaasy there darling, I am simply getting a feel of your nethers. You can't expect me to pleasure you without getting properly set up can you?" Fluttershy writhed in pleasure as she felt small, but powerful twitches and strokes all through her nether-lips.

"W-what are you d-do- FUCK!" she gasped and shut her mouth. "s-sorry..." She said with a mortified look in her eyes.

"Well well, and I thought your mouth was going to be filthy later...such language my dear....mmmm is fucking required here Fluttershy darling. As to what I am doing...well I am getting a feel for all your nerves, muscles and well, practically every muscle of your vagina. This is rather paramount if you want to become a good little shit eater. Instead of simply having my pet here sit UPON your muzzle and flood your insides with his rather delectable shit...I am going to have him do just that...but while pleasuring you beyond the capabilities of your mind. This of course will imprint the very idea of eating shit, playing with it, what have you...with the most intense pleasure imaginable. Mmmmm for myself, even the act of taking a shit  pushes me well past the point of orgasm. With all of this in mind, if you wish for him to stop for ANY reason..." as she spoke that crop floated into Fluttershy's grasp. "Simply thwack that across his ass at ANY time and he will stop. To have him continue...well give his hole a kiss. Are you ready? also don't you worry about leaning up to his ass, I have these lounges for a reason. When you are ready, kiss his pucker."

Fluttershy stared at Rarity, then up to the massive ass hovering inches above her muzzle. She was going to do it, she was going to have a pony shit down her throat. With one final gasp she nodded, and pressed her lips to the stallions ass. The very second she did, Rairty began to manipulate and pleasure Fluttershy's depths with her magic. Knowing she was ready now, and getting the nod from Rarity, Big Mac pushed his ass gently against Fluttershy's muzzle. Fluttershy let out a sharp gasp from the sudden immense pleasure that Rarity was giving her. He tongue darted out and began to flicker across the stallions leathery pucker. *Hnggggggg!* Fluttershy arched her back upon hearing that moan. Her body swirling with ecstasy and lust. While she rimmed Macintosh, she felt his tailhole open up, allowing her tongue to probe deeper. The smell was aweful, musky...but intoxicating. With a great amount of control, the stallion began to push his first 'bushel' into her mouth. The yellow mare gagged out as the first lump was pushed into her muzzle. Her legs twitched and kicked under her as she began to chew, each time retching from the taste. Rarity moaned under her breath as she focused on pleasuring her friends cunny. Fluttershy whimpered as her tongue slathered over the stallions lumpy manure. After the initial bitterness was gone, she tasted a rather pleasant sweetness.

"Mmmmmmmmffff!! mfff.mffmmm... mfffrrrr!!" she moaned out as she swallowed down the first lump, feeling her nethers about to explode. Rarity watched as her throat bulged out with Mac's first lump.

"O-ohh goodness! so quickly?!?" she gasped with pleasure. She focused more on Fluttershy until she flew over the edge. Fluttershy could feel herself pushed to a plateau of pleasure she had never felt in her life. The yellow mare screamed out into the thick stallions ass, throwing the crop off to the side. She began to hump the air wildly as her hands reached up to grip Mac's hips. A greedy feeling began to fill the Pegasus as Rarity kept her right on that wonderful plateau.

"M-mmmmmrrrrr!...Uh...wmmtt..mrrrrr!!" she screamed out while practically making out with his pucker.

"Y-you heard her darling...no hold-holding back now. Feed the scat hungry mare your meal, w-we wouldn't w-want to keep the poor thing waiting" she said moaning heavily, and in between heavy breaths. Big Mac nodded and pushed his ass down onto her muzzle, practically sitting on her face. The yellow mare reacted by gripping both of her breasts, pushing them together in an attempt to contain the amount of explosive pleasure she was feeling. *Un...unggggggfff!!!!* He moaned out again and began to push as hard as she could. Fluttershy felt a good three or four lumps get instantly shoved into her muzzle and down her throat. Her hands did all manner of goofy motions and actions as her mind was lost to the session. One of them rather quickly found his shaft, and wrapping around it. Her other hand soon followed as she gave her stallion feeder one amazing 'rusty trombone'. Big Mac let out a deep lust filled nicker as his shaft was stroked. "F-fuck...B-big Mac..y-you have m-my permission to c-c-cum...once you have f-finished fee-feeding her..." Rarity moaned out. With that, Mac rested his hands on his thighs and pushed once more. Again fluttershy felt her mouth swell up with his rich, bittersweet manure. She had long given up on chewing each piece that he pushed out for her. Fluttershy just sat there and began to swallow, letting her belly fill up with her meal. The once slim and petite belly of hers was now bulging with that stallions shit. With one last push his tailhole was empty. Fluttershy began to hungrily chew and slosh that final piece in her mouth as though it were the first food she had consumed in months.

"I....w-words..I..nfff... horny...ne-need..." Fluttershy writhed with the shit still within her mouth. Both hands releasing his shaft. Her eyes looked to Big Mac with wanton lust burning within them. Her hands slid down to spread her lips. Mac glanced back to Rarity with hopeful eyes.

"Wrap yourself then you may fuck." Rarity moaned out as she pulled the toy from her nethers. "F-fluttershy dear..I simply MUST ride your face after watching that....would you allow me?"

The once quiet and shy mare responded by opening her muzzle, showing that half dissolved lump. Rarity clenched her thighs together and walked over to Flutters lounge. She quickly climbed up and straddled the mare's face, with her hands gripping the back of it. With a look over her shoulder, she saw her pet was wrapped-n-ready.

"1....2....3!" she called out. In perfect unison Rarity and Mac pushed themselves onto the writhing mare. Fluttershy screamed out in pleasure, gripping the lounge as tightly as she could. Once those soft folds of her unicorn friend were upon her, Fluttershy shoved that filthy tongue inside of her. "Oh-Ohhh my!!!! F-fluttershy!" she gasped loudly, feeling that sludge covered tongue invade her nethers. "M-M...Mac...you are free t-to release a-as you wish....but p-please b-be a dear a.and KISS MY ASS!!" Shouted out the white unicorn. Big mac reached up to grip ahold of Rarity's ass, and driving his tongue deep into her pucker. The three of them engaged in a filthy threesome of unmeasurable proportions. Each thrust that Mac delivered into Fluttershy, caused the yellow mare to eat her unicorn out with a more heated ferocity, which then caused that pleasure drunk white mare to grab the back of Macs head as she farted lewdly into his mouth...which caused the whole cycle to repeat. Mac was the first to cum, his shaft exploding like a geyser inside of the lust driven Pegasus. Unknown to the three of them that the condom burst the second he fired into it.

Not soon after the big stallions release did Rarity scream out in ecstasy as Flutters filthy tongue sent her flying over the edge. Her body began to spasm with her release. Big Mac quickly grabbing a hold of her, and laying her down with the two of them. With rarity's mound off her muzzle, and that massive stimulation dying down, Fluttershy was finally able to sink into her lounge. She idly rubbed her swollen shit filled belly before passing out next to Rarity. Big Mac stood there panting before slumping over on the other side of Fluttershy...his cum slowly oozing out of the yellow mare.
