>Funny, Twilight didn't remember going to sleep wearing cuffs
>Especially not with those cuffs restraining her into an all-too-vulnerable splayed out position>And while Anonymous always delighted in bound in some rump-revealing way, he wouldn't be so cruel (or deft) as to do it while she was asleep.
>Besides, this didn't feel like that.
>Anonymous (and Rarity, as her friend traitorous housemate had largely instructed him) tended to restrain her in revealing positions, but...
>As she squirmed, listening to the chains clink, she knew this felt different.
>Vulnerable.
>Since when had Rarity (or Anonymous) used chains, anyway?
>"'non'ous?" she called through the gag painfully wedged between her jaws.
>Ah, so she was gagged too.
>A bit gag, by the feel of it, linked to the bridle painfully cutting into her muzzle.
>Well, it wouldn't be the worst thing she'd had in her muzz-
>Movement, behind her.
>A pony's hooves on the cold, hard floor.
>Twilight's head could not turn in the bridle's unrelenting grasp, but her eyes could roll about to stare, until they ached, at the mare circling her.
>"'rari-"
>It was not Rarity.
>Though what she wore might have been Rarity's design, given that the form-fitting harness did everything leather, steel, and strap could be asked to do for the mare's figure.
>And what a figure.
>Twilight knew her own body was... lusciously proportioned, while Rarity had always prided herself on an elegantly-sculpted form.
>But the room's harsh, sharp lights cast this mare's yellow coat in a chiaroscuro pattern of light and dark, highlighting a body that seemed not so much shaped as carved.
>Yet it was also a body bound in shackles just as Twilight's was; though her bridle was bereft of bit or gag, it was a bridle nonetheless.
>Fiery orange eyes regarded Twilight, sending a prickle of fear down her back and suddenly reminding her of just how vulnerably posed she was.
>But it wasn't until she saw the cutie mark that it clicked in her head who this fierce, predatory creature was.
>"Spi'fire?!" Twilight tried.
>Spitfire's wings shifted sharply, and Twilight gave a cry as something struck a blazing line into her rump.
>When the wings settled again, Twilight realized that the cuff which bound each halfway along their spans had also been fitted with careful tools.
>One held a thin, supple whip - the instrument which had just struck her - while the other held a curious three-clawed hook whose purpose Twilight did not care to speculate on.
>"Miss Spitfire, Ma'am, or Teacher," the golden-coated mare said, her voice low and yet still managing to put a shiver down the length of Twilight's spine. "I am not your Mistress, but I will not be disrespected."
>'What the fuck,' Twilight thought.
>"Wha' d'fu-"
>Another flick of the well-muscled wing, and another trace of lightning across her rump.
>Twilight went still, and Spitfire smiled.
>She had canine teeth, Twilight thought. Almost no mares had those.
>Twilight did not at all like the way Spitfire smiled now.
>That look of nervousness caught in her eyes, and the whip-bearing wing extended again - slipping its implement beneath Twilight's chin to keep her head still.
>"Your Master and Headmare," Spitfire began, "have mentioned to my Master that you have - issues, with self-control. He says you are 'disobedient'."
>Oh, fuck.
>FuckFuckFuckFuck.
>"My Master has agreed to lend me to yours, so I can help with these issues."
>Twilight started to say something, and the whip's tip ever-so-softly tapped the bottom of her chin.
>Twilight stopped saying anything.
>"I want you to understand one thing right from the start, Twilight Sparkle. I do not prefer punishment. I do not like punishment. I use it, but fighting disobedience with punishment solves... symptoms. Not sources."
>Turning aside, Spitfire began to walk again - once more outside of Twilight's vision.
>But still she spoke.
>"What I teach, Twilight Sparkle, is discipline. Punishment only comes after the disobedience; discipline prevents it in the first place. Do you understand?"
>Say yes, Twilight.
>Say yes, and wait until she takes out the gag so you can explain.
>"Ye'h." Then, a moment later, "AAAGH!"
>Another line of white-hot pain on her rump.
>This one hurt more than either of the first two, and Twilight was suddenly struck with the awareness that she was in trouble.
>Rarity and Anonymous both had delivered intimately painful lessons on obedience.
>But they were a fashionista and an average human; Spitfire was an athlete.
>How long would she be able to keep up on her poor plot?
>"Ye'h, Mish' Spi'fire!"
>The bit kept it from being a real answer, but despite Twilight's cringe, no fourth stroke came.
>"Good. I talked to Rarity already, and she explained that your Master has already taught you some degree of discipline with some parts of your body."
>Something probed beneath her tail, and Twilight froze.
>No, no, no!
>This wasn't sexy, it was scary!
>(Okay, maybe it was kind of sexy in a scary way)
>But not like when she let either Rarity or Anonymous take her!
>Thank Celestia the probing there stopped - but the fear did not go away.
>If this was what Spitfire had been set to do...>When the mare stepped back into Twilight's vision, a pair of capped vials were tucked beneath the pegasus' wing.
>Both were taken out, carefully set on the floor before Twilight.
>"...clearly you need more discipline, though. This will teach you exactly that."
>"Wha's 'at?" Twilight whimpered around the bit.
>"We're going to share a drink," Spitfire replied with a smirk. "I think you've experienced this formula - and its effects - once before?"
>It took Twilight a moment to realize what she meant.
>Only then did the true panic set in.
>The last time, when that doctor had given her that wretched estrus-inducing brew, it had been nothing less than utter torture.
>At least then she was spared continuing torment by Octavia; now, Spitfire's stern ministrations were all she had to look forward to.
>"P'eashe..."
>Yeah, Twilight was definitely not too proud to beg.
>Not before this.
>But Spitfire only firmly shakes her head, then set about strutting back and forth in front of the bound mare - showing off every inch of her firm, lithe form, the buckles of her harness and chains of her shackles jingling with every step taken.
>"What you lack is discipline, and I am going to instill it. Here is how this is going to work, Trainee: We are both going to drink. Every time you whimper, whine, plead, or otherwise show an inability to discipline your body and mind, you will receive one stroke of my lash."
>Already Twilight flinched just in mere anticipation.
>If that was the requirement, her rump is as good as roasted!
>"...an 'oo?"
>"And me, Twilight?" Spitfire grins, showing off her canines again. "I will drink too. And I will show you exactly how a mare with discipline behaves. When you can restrain yourself, then we won't need these... stricter restraints to aid you."
>" mer'y?" Twiligh tried pitifully, eyes wide with pleading horror.
>"Mercy? This isn't cruelty, Twilight. This is self-improvement. This is education. So - bottoms up, Twilight Sparkle."
>The first vial was forced to Twilight's lips, pressed through where the bit cruelly tugged at her flesh.
>She tried to spit and blow the horrid stuff out as it poured onto her tongue, all metallic and bitter-tasting, but Spitfire forced her head back with practiced efficiency and ease until the last drops fell down her throat.
>Only then did Spitfire herself tilt back the second vial, downing it in one swift gulp.
> ...
>Every moment seems to stretch to an hour, every heartbeat to an eternity.
>Celestia taught that anticipation made every breeze into a hurricane, and how to push that aside.
>But Celestia never dealt with this (and Twilight frankly didn't care to think what this horrid brew would do to her).
>She had never had to lay there, shackled tightly in place, wondering if each itch or twinge was the firsts surges of unspeakable heat boiling up from within.
>The only immediate mercy was that Spitfire didn't seem to take Twilight's squirming as a lack of discipline; the whip was mercifully still.
>Even so, Twilight had to wonder, Spitfire couldn't be far behind her in feeling it.
>What was that mare's problem anyway?!
>What kind of madmare actually drink this stuff without-
>"Gah!"
>Somehow, despite her vigilance, the first twinges of need had snuck up on her without warning.
>That horrible, deep incessant need growing from deep within Twilight, filling her marehood with-
>SWIP-CRACK
>"Eeep!"
>The line of white-hot fire laid into her rump was almost a welcome distraction from the growing need.
>Almost.
>The whip Spitfire was using was far, far worse than any paddle or brush her Master or Mistress had employed; it seemed to lay its fire deeper into Twilight's rump.>Worse, it drew her attention to her hindquarters.
>A whipping across the back, thought Twilight, might almost have been welcome.
>Then she could have had some distraction from the all-consuming itch radiating from between her haunches.
>Already she could feel herself growing damp, growing swollen and prominent back there - her tail was already up, and she didn't even know when she'd-
>SWIP-CRACK
>"Ahhhh!"
>"No whining," Spitfire sternly snapped, tucking the whip back to her side.
>Had she been whining?
>Already, when the need was still grow-
>Ah, fuck!
>The need!
>Just thinking about it sent a fresh tremor through Twilight.
>Something wet trickled down along her haunches.
>And-
>SWIP-CRACK
>"No wriggling, Twilight."
>"Oh, co'm on!"
>"No. Wriggling," Spitfire insisted, though at least she did not deliver a third stroke with that terrible whip.
>No wriggling?!
>How was that even possible!
>Every second the need seemed to grow; maybe it was only her memories of Gentlehoof fading, but this feels even more intense than what she'd experienced there.
>Now it felt like a monster tearing its way through her mind, reaving away reason and thought to leave only pure, acidic lust in its wake.
>Celestia above, that need was strong!
>She needed a cock in her now.
>Right now.
>She needed it pounding, pounding until it filled her-
>"Guh-!">Oh, that wink.
>She felt that wink.
>She felt the fresh splatter of wetness running down her haunches.
>And she flinched in anticipation of-
>SWIP-CRACK
>"Yeep!"
>Another line of white-hot lightning laid into her rump.
>Spitfire certainly wasn't holding back.
>Now-
>Spitfire.
>Focus on Spitfire - that traitorous, sadistic whorse - instead of herself.
>How was Spitfire even bearing it?!
>She had only taken the drug seconds after Twilight, surely she couldn't be that far behind!
>Twilight focused her eyes on Spitfire.
>She seemed so - calm.
>Standing near perfectly still, except for her deep breathing, and maybe a twitch of her ear.
>How?!
>Even her tail was being held perfectly low and proper; was she some kind of freak, a mutant?!
>Maybe Spitfire wouldn't mind helping her out a bit.
>She didn't have the cock Twilight needed, but a tongue would be perfectly good right now.
>And Spitfire probably had plenty of stamina; she could keep Twilight going for hours until-
>"Nnngh!"
>The thought of the well-muscled mare burying her muzzle deep beneath Twilight's tail was just too much.
>Twilight felt herself wink again, and worse felt her hips buck up to meet the imagined tongue.
>SWIP-CRACK, CRACK!
>It might've been a whimper that emerged from her lips, or it might have been a moan.
>The drugged fog filling her brain made it hard to tell.
>The result was the same.
>"Your Master was right. You really don't have any discipline."
>As Spitfire settled back into her passive, waiting stance, Twilight tried to wrench her focus back to her tormentor again.
>This time, the signs were a touch more obvious.
>Spitfire's breathing wasn't just regular, but tightly controlled.
>Her wings were stiff and rigid at her sides.
>Muscles stood out beneath her coat, held tense and powerfully.
>Her lips moved just a hair, whispering something beneath her breath.
>It was still an unthinkable display of willpower, but at least Twilight knew Spitfire was feeling it!
>What would it be like to see Spitfire break?
>To see her squirming, writhing on the floor, desperately pawing at her marehood-
>SWIP-CRACK
>This time Twilight even managed to brace herself a second before the whip landed.
>Not that it made the experience much better.
>Especially when her thought that Anon's paddle hurt so much less, was promptly followed by another twitch-inducing wink at the thought of Anon seeing her like this.
>Why couldn't he?
>He'd ridden her through natural heats before.
>If he could have joined her, or even him and Rarity both with that monstrous plastic toy of hers, and given her relief after relief-
>SWIP-CRACK, CRACK, SWIP-CRACK!
>"AUUUUGH! Wha' di' I do?!"
>"Your tail is swishing," Spitfire said with a slight grin, "well, actually more like lashing. It's making a mess, you know. You're making a mess."
>FUCK!
>She is breathing hard too, and it's clearly not from exertion - even as another three lashes drew yet another howl from Twilight's lips.
>"You really need to get that tail under control. If there were a stallion back there-"
>SWIP-CRACK
>The thought of just being seen like this was enough to get her hips rolling.
>Because any stallion, human or pony, who saw her like this wouldn't hesitate to-
>SWIP-CRACK
>Now wetness joined her cheeks as well as her rump, where the first tears dripped from her eyes.
>Spitfire opens her lips to say something.
>Before she can, a barely-perceptible ripple ran from nose to tail down her body.
>For the first time Twilight became aware that the overwhelming musk of her desire wasn't the only scent in the room.
>Aware of the splattered pattern of dampness beneath Spitfire's hips.
>In an instant, Spitfire was back:
>Perfect, composed, ironclad in her self-control.
>But now Twilight could see through the mask.
>She could see the little tremble of her lip, barely revealing a hair of the sharp canine tooth that had seemed so fearsome a moment ago.
>The subtle twitching of her tail, hinting at a barely-held back furious lashing.
>How rigidly and tensely her wings were held at her sides.
>Well, Spitfire wants to test her discipline does she?
>When Twilight felt the next wave of urge rising, this time she didn't bother trying to distract herself.
>She let the furious, ravenous need wash over her, soak into her.
>Her hips rolled as she winked hard, bridle and bit tugging hard (and perhaps a bit desirably) into her flesh, a rich and lusty moan escaping her lips.
>Her desire audibly splattered on the floor as she winked, hocks now thoroughly soaked in her need.
>'Fuck', Twilight thought, 'that was a mistake! I want something inside of me so much it almost hurts-!'
>But the reward was worth it.
>Spitfire grimaced, taking a step forward.
>And then stumbled.
>She gasped a short and shallow breath, her eyes focusing one somewhere far beyond.
>"/Slampa!/" Spitfire swore in muttered Pegasi, "that one was bad."
>Twilight allowed herself a strained grin - but it was a grin that fell apart as Spitfire refocused on her.
>'Uh-oh.'
>"So," Spitfire hissed slowly, "You think you can break me, do you?"
>"Nooooph?" Twilight tried hopefully.
>"You might be able to play that kind of game with that ivory plaything your Master keeps, but not with me."
>SWIP-CRACK
>"Agh!"
>SWIP-CRACK, CRACK, CRACK!
>"I think that little display might be worth about ten; what do you think?"
>Oh, no.
>No, no, no.
>This was really bad, Twilight thought.
>Strokes of the whip landed at a regular drumbeat across her rump, each one seeming to plunge the fiery pain further into her flesh.
>Yet, even so, now that she had let that relentless desire into her head, it wasn't possible to get it out again.
>Every hair of her coat practically itched with need.
>Her marehood was a furnace of heat, and even as the latest lash struck home, Twilight felt herself wink again and moan breathily.
>It seemed another eternity before the whipping ceased; her entire rump felt alight with sizzling lines.
>No doubt it was covered by a spider's web of welts now as well.
>Spitfire circled her again, eyes wild and wide.
>"You know, in some ways, I envy you, Twilight Sparkle."
>"...mguh?"
>"You don't even have to try to hold back. You have it easy. The chains, the harness, the ring on your horn - they all do the work for you."
>That bitch.
>That utter bitch.
>Putting you in this kind of situation and then telling you it was easy!
>"I bet if you were free you'd light that horn and rub yourself senseless right now, huh?"
>"...mmmyeshh.."
>The admission came with a heavy, burning sense of shame - but also realism.
>The burning itch was utterly maddening.
>"I-" Spitfire's haunches shuddered, muscles clenching tight until they stood out once more. "I don't have that luxury. That easy way out."
>"Then... pleash..."
>"Please what, Twilight Sparkle?"
>Twilight surged forward, chains snapping taught as she leaned into the other mare - smelling the husky scent of her own need.
>"Pleash! Hel' meh! Ton'guh! I gif up, 'kay? You're shtron'er, I'm weakuh, jush PU' Y'TONGUH IN'IDE O' ME, I NEED IT I NEED I NEED I NEED-"
-----------------------------------------------------------------------
>Spitfire fell deep into a bow, her muzzle wings spread low to brush the floor.
>"I failed, Master. I completely failed."
"Oh?"
>"She's... completely untrainable."
>Turning her head, Spitfire looked back at the now-limp form of the purple unicorn, slumped in her chains.
>"I could beat her into playing along, but that's not what you asked me to do."
"No. It isn't."
>Spitfire nodded. "You could get obedience out of her, to avoid the pain. But never discipline. Never self-control. I've failed, Master. Whatever punishment you give, I'll accept."
"She got through to you, didn't she?"
>"...yes, Master," Spitfire conceded and seemed to sink even further. "I tried to not let her, but... the two of us, both deep in the heat together..."
"Well, then."
>Two vials, heavy with the thick potion, were set in front of her.
>Spitfire looked up, brows knit.
>"Master?"
"One for each of you again..."
>In the background, Twilight stirred in deep-seated terror.
"...and this time, you'll be eating her out the whole time. So much as think about touching yourself, and it'll be worse."
>Spitfire gasped, the depth of her punishment beginning to sink in.
>"Yes, Master."
