Flutterbitch x Twilight
Fluttershy was in a bad mood. A very, very bad mood - the sort of bad mood that makes even the largest tub of ice cream unappealing. The sort of bad mood that fills one's heart with an empty feeling of loathing for just about everything. Fluttershy liked this feeling an awful lot. It was liberating, in a way, finally being given a spine. Finally being able to properly speak her mind, and do things just because she wanted to. Finally able to just stop caring about everything else, and concentrate on who's important in her life - her.
She didn't exactly have any plans, having just left Twilight and the rest of her so-called friends behind after a spectacular failure at using the useless Elements of Harmony, but she didn't particularly care about that either. This was her time, she could walk the lands, taking what she wanted and going anywhere she felt like. It sounded, to her anger-filled brain, like a plan.
Appearing in a flash of light and with an entourage of doves bursting out around him, Discord, the lord of chaos and Fluttershy's current benefactor, appeared in front of her. "What the hay do you want?", Fluttershy spat at him, not seeing the need to make her appreciation known.
"Me, want? Oh, my dear, I have everything I came for! Equestria is mine, chaos rules, and your little friends are all sad and broken. Perfect!" he said in a sing-song voice, hopping around in happiness, "But, alas, your buddy-and-pall Twinkle Sparkly is feeling pretty down, pretty grey, and just all round miserable!"
With a snap of his fingers, each dove pulled out a little trombone and played a very impressive sad-trombone-noise chorus.
"So? Why should I care what that little bookworm gets up to?" Fluttershy sarcastically laughed, with a sneer, "if she wants to go cry in a corner, let her". Fluttershy started to walk on, towards the candy-cane wasteland that used to be the Everfree forest, prompting Discord to float along behind her, skating through the air on two tiny skateboards.
"Because, my dear Fluttershy, Twinkly is feeling so terribly alone, and she just wants to belong!", he said with a knowing smile, "so why don't you make her belong... to you? Or not, I don't care, I have what I want, I'm off for another few millennia of chaos, destruction, torture, and so on - fun! She's heading back to her tree thing, by the way, so don't be late!"
Transforming into a dove himself, the swarm flew into the distance, forming shapes wide and varied as it went. Fluttershy was left standing there, thinking hard about what Discord had just revealed to her. She didn't fancy having to provide for somepony else, but on the other hoof, it would be nice to have somepony to boss around. It'd make getting her own way easier, too, if she had somepony like Twilight to do her bidding. It was decided then, Fluttershy thought, as she took off with a confident wing-beat.
Twilight, at the time, was slowly shuffling her way back to her library to... she wasn't sure yet, but go somewhere else. Grab her stuff, and start walking. Leave everything - everyone - behind her and start over, didn't really matter where. Stepping up onto the porch of her library, Twilight looked behind her, over the unruly landscape of new Ponyville, and over the bendy horizon of the un-setting sun. She spotted a tiny shape, so far away, silhouetted against the bright orb, and waited a few moments for the time of day to switch again, revealing it to be Fluttershy, flying at her with a determined look on her face. Twilight's heart twitched - she didn't need anybody, but... it'd still be nice to have friends. Not that she needed them. Not that she wanted them, they just get in the way, but a travelling companion isn't a friend, is it?
Her hopes were crushed as Fluttershy, perhaps deliberately, overshot, knocking Twilight to the ground and pinning her down. "Fluttershy, get OFF ME", Twilight started, before Fluttershy jabbed a hoof into the side of her neck and hissed at her.
"Shut up, twinkle star, this is all your fault anyway. Maybe if you'd been good at magic we wouldn't be here, would we?"
"Fluttershy, I... I..." Twilight whimpered with the start of a tear starting to form in her eyes. Was it her fault? Of course not, Discord was just too strong for them. But then... if she'd been stronger? Maybe Fluttershy was right, Twilight was meant to save the day. It was her destiny, her duty as Bearer of Magic, and she failed. At her duty, at her destiny, at her very reason for being.
"Oh, boo hoo, sprinkles, shut up and try and be good for something. I can't stay here, I'm gonna go travel somewhere. I always wanted to see the world, now I will, and you're coming with me, I need somepony to carry my stuff.", Fluttershy forcefully snarled into Twilight's ear, enjoying feeling her squirm beneath her hooves, "Maybe have a bit of fun with you, or throw you out there if I need some bits, I know you're into that"
"F... Fluttershy, I told you that in confidence! How could you?". Twilight was sobbing freely now, Fluttershy doing almost as good a job of crushing her spirit as she was at crushing her weak body.
Fluttershy raised a hoof and pressed it to Twilight's face, punctuating each word by pushing her further into the dirty as she said "boo hoo hoo, I'll do what I want to you, get it? It doesn't matter who you were, you're mine now, okay?"
Hopping off and kicking Twilight around until she was lying flat on her stomach, the tears still rolling down her face, Fluttershy continued, pressing the flat of her hoof against Twilight's horn and using it to lever her head deeper into the mud, "and you will do, as, I, say, get it, sparkles?"
Fluttershy felt Twilight's horn twitch up and down as she fitfully attempted to nod against the hard ground. Fluttershy grinned - she guessed that Discord really had been right, Twilight did just want to know her place. Maybe she could show a little kindness, just for old times take, and tell Twilight just who she is now, in this new world where everything's changed and nothing makes sense any more.
"Okay, trinket, here's how it's gonna work. You're mine, you do what I say, you don't argue, speak without being spoken to, answer back, do ANYTHING I don't like, and maybe I'll let you keep some of the food you're going to be taking for me, get it?", Fluttershy whispered into her thrall's ear, almost seeming kind were it not for the words she was speaking.
"O... okay, Fluttershy, but please call me Twilight. Please" Twilight submitted and begged in return, looking upwards at Fluttershy with pleading eyes. Pathetic, pleading eyes, according to Fluttershy's unsympathetic mind.
"Didn't you listen, you stupid bitch? It doesn't matter who you were, I'll call my stuff what I want to call it, and you'll call me what I want you to call me. Miss, or mistress, or owner, I don't care, you're the bookworm, make it up. But I'll call you whatever the hay I like, and you", Fluttershy paused both for effect and to bring her hoof into position, "you won't complain, and you won't argue, and I'll not hurt you too much." The hoof jammed down - hard - into Twilight's half-exposed vagina, the almost dripping fluid betraying just how much she did want to feel like she belonged.
"Ye- Yes, master!", Twilight moaned as Fluttershy's forceful hoof slid over her slit, rubbing her clit until it slammed into the ground, sending a small puff of dirt and small sticks flying around. Taking Twilight's submission as a perverse admission of approval, Fluttershy slowly raised her hoof, scraping the hard edge along the inside of Twilight's needy walls. Raising it clear, and still slick with Twilight's juices, Fluttershy thrust it towards the purple mare's crying face.
"Lick it clean, sparkly sluthooves", she demanded of her new pet, pushing the pungent limb into Twilight's muzzle as she obediently opened wide, running her tongue over and around Fluttershy's hoof, lapping up her own arousal even as it mixed with her tears in her mouth as Twilight began to come to terms with her new position underhoof. As Twilight finished cleaning Fluttershy's extended limb, it pushed put, knocking her back to the floor and back into the dirt, and the small muddy puddle that rested immediately below her dripping vag. "You gonna beg, twinkle? Beg for it? Like a dog?" Fluttershy sarcastically questioned, laughing as Twilight whimpered in front of her and struggled back to her hooves.
"Please, proprietress, please more, I beg of you" Twilight pleaded, her eyes betraying how far gone her mind was to lust and subservience, Discord's mind-work rendering her self-confidence useless to her.
Fluttershy's smirking face grew to a snarl as she lashed out with a hoof, dizzying the poor unicorn, before she flipped round and bucked straight at Twilight's head, knocking her feet away and to the ground in a daze. Staring down at the heap of sodden, dirtied flesh at her hooves, Fluttershy laughed, "Oh look at you, soaking wet and clueless yet again. I told you, glimmer, you don't get to ask for horseapples, so shut the hay up and do as you're told", she explained to the shaken pony in front of her as she rolled onto her back, "now prove you're not completely stupid and put that tongue to use".
Twilight, holding back a sob, and trying to fight her almost overwhelming urge to just drop her hooves and start masturbating, only managing to stop herself because she knew her owner hadn't given her permission yet, struggled a hoof out as she started to crawl back over to Fluttershy, ignoring the way her dirt and blood soaked mane covered her eyes as she pulled.
Reaching her goal, Twilight nuzzled Fluttershy's sweet entrance, taking in her heady musk and appreciating her dominant's smells before she dared to taste. Gingerly poking out a tongue, Twilight winced as she made contact, thinking of all the ways her lord tasted better than she did. Sweeter, less bitter. She ran her tongue from the bottom up, making sure to catch Fluttershy's clit with her nose and rub her muzzle along it to ensure she was pleasuring as well as she could, before finally reaching it with her tongue and giving it an enthusiastic lap.
Fluttershy grunted up above, pleased with her toy's progress and too far in the throes of ecstasy to care about being mean, starting to thrust lightly into Twilight's attentive mouth as she began to delve deeper, probing her tongue between Fluttershy's folds and filling her with a wet, sticky warmth, leaving her whole face sodden in Fluttershy's luxurious liquids as her eyes started to roll up in pleasure, just from the mental exhilaration of complete submission.
Taking what little initiative she felt comfortable with, Twilight grasped out with her hooves, holding her yellow master's flank tightly and pulling herself in, managing to insert the whole front of her face even while she opened her mouth and kissed inside, her tongue writhing around and darting from place to place as she tried her best. Repurposing a hoof, she started to rub Fluttershy's clit, lubricated by both Twilight's saliva and a mixture of both of their emissions.
Hearing Fluttershy moan and gasp more loudly above her, and feeling the amazing thrusts against her face grow harder and harder, Twilight became more and more enthusiastic in her rubbing and licking, seeking to follow her orders as well as she possibly could in some last-ditch effort to give her life meaning once again.
Twilight closed her eyes just in time as Fluttershy's pleasure peaked as she achieved orgasm, sending waves of liquid shooting out onto Twilight's head and squirting onto her face, drenching and matting her fur and mane, and leaving her looking as if she'd just gone swimming. Twilight leaned back and sat, obediently waiting for further instruction, while she watched Fluttershy wordlessly gape for a few moments before she struggled to her feet.
"You'll do", she spat, "now come on, you've got a lot of stuff to carry and I want to keep up a good pace."
Fluttershy hopped up and started to fly away from the library at a good pace, causing Twilight to compliantly gallop behind her, getting further and further away from Spike, as he burped out letter after letter.

"Hey, zazzle, we're gonna need a fire. Go grab some books from that library of yours and meet me back at my house"
