Predicament

“Are the knots secure, love?”

Hemp and fur and steel rustled against each other as Twilight Sparkle wriggled her hind hooves. A thick spreader-bar held her legs apart. She could only totter a half-inch in any direction before the ropes binding her to the bar held tight. She struggled harder, trying to kick away the knots and thrash out of them. Mere moments proved her efforts futile.

Twilight willed her legs to settle, a dark little thrill running through them. “Yeah, they seem, uh, pretty tight.”

The purple unicorn stood on the cream dais in the Carousel Boutique. A dozen full-length mirrors stood around the dais allowing Twilight to see her reflection from every angle, though they were for her partner’s benefit rather than hers tonight. A dull steel pulley system loomed above her with a hook dangling limply below, in stark contrast of the dainty, elegant decor of the rest of the shop. She fidgeted, and looked down at the selection of ropes and toys laid on a royal blue cloth, waiting to be used.

Just like her.

Two lengths of twine lay sprawled on the floor, tied to each of her forehooves at one end, limp in coils at the other. Her mane was pulled back into a pony-tail and this was wrapped into a bulky, softball-sized knot with thick hemp rope which ran upwards to the pulley system, dangling loosely.

Rarity walked behind her lover, trailing a delicate touch of magic over lavender curves as she did. She reached the wheel attached to the pulley, and began to turn. It clinked and clinked and clinked until the rope tied to Twilight’s mane was taut, and clinked until it pulled her mane upwards, squeezing tears into her eyes and tightening her throat, and clinked until she pushed off with her front legs and stood uneasy on her spread hindlegs, tottering precariously.

The wheel spun faster under Rarity’s hoof, turning the clink into a creaking whirr, until the rope between Twilight’s mane and the pulley was taut once more. The last few clinks came slow, forcing Twilight to stand perfectly upright on two hooves or dangle painfully from her tied-back mane.

Her breaths came in gulps and went out in shudders. She wobbled her front legs to and fro for balance, desperate to take any measure of strain off her scalp. The wet glimmer of tears around her eyes matched the sight of the slick, dewey slit between her spread-wide legs.

“How are the bonds? Nothing feels ready to snap off, I hope?” came a voice from below.

“Glhhrk.” Twilight coughed and cleared her throat. Talking while suspended so was new to her, and her voicebox didn’t want to cooperate. She tried again. “Good. It’s very tight.”

“Does it hurt?”

Twilight couldn’t tell if that was concern or lust in Rarity’s voice. She didn’t care. She tried to nod, and squeaked with pain as all the hairs on her forehead were yanked backwards. “Uh-huh. Good hurt.”

Rarity reached up and touched a hoof to the soft fur of her lover’s neck. “Shall we continue, then?”

Something went on a rollercoaster inside her, dropping into her stomach so hard it made her belly quiver, and then shooting up into a grin that she couldn’t even try to hide. “Yes, Mistress.”

Rarity’s eyes went down, and then came up alongside a devious grin. “Wonderful. Are you ready, my darling Twilight?”

* * *

“I’m ready. Wait!” Twilight paused, and looked away from Berry’s Bar and out into the streets of Ponyville. She made the most of her pause before speaking again. “Right, okay. Sorry,” she said, as if she’d forgotten about the unicorn next to her.

Rarity just giggled, covering her mouth with her hoof in that delicate way of hers. “Darling, it’s fine. It’s perfectly normal to feel like this before your first munch.”

“I know, I’m just... I’m being silly about it. I’m ready. Really.” Was that a lie? It felt like one. Her icy gut and leaden hooves agreed, and the constant, nagging anxiety behind every thought in her brain said she wasn’t prepared, that she was walking into social territory flagrantly different from the norm and therefore tenfold as danger-fraught, into a scene she knew nothing of but Rarity’s honeyed words, her sharp caresses, and the spicy little picture books locked away in her bedroom desk, all of those things mere sand and straw against the storm she was facing. If she was painfully honest with herself, ten years of careful study wouldn’t be preparation enough for this ill-advised dive into lunacy.

The rational part of her mind clambered over the ‘honest’ part: Preparation was a continuum. There is never a ‘completely prepared,’ and she knew that no time in the world would make her feel that way. There was only ready, and ready was thus: Twilight Sparkle, of sound and somewhat sober mind and in possession of all her physical faculties, was ready to meet the sex club.

Sex club. Element of Harmony and Faithful Student to the God-Princess of Equestria. At the sex club.

Sex club.

Sex club. It sounded sordid in the most abstract, general ways, and every specific way Twilight could think of made it sound far more sordid than even that.

She’d been intrigued from the moment Rarity had mentioned it. Even if she chickened out tonight, she’d be waiting outside Berry’s at the same time next week. There was no point in waiting. She was ready.

“I’m ready,” said Twilight Sparkle. She looped her tail over Rarity’s and they walked inside, through the busy bar and into the booths in back, where the Ponyville Omni-Knot Enthusiasts awaited.

* * *

The binder clips came first. Springy steel, glossy black, prized by librarian and designer both for their usefulness, prized doubly so by Twilight Sparkle and Rarity for their versatility. Rarity had a bucket full of them in her inspiration room. Tonight, she only needed two.

Rarity stood on her hind-hooves, bracing herself with one foreleg around Twilight’s neck and the other around her shoulder, increasing the weight and strain on Twilight’s bound, upright form and stealing another yelp from her lover. She pressed in close to her, white chest on purple fur, warm like cocoa on a winter’s morning.

Twilight strained to stay upright and not fall painfully slack against her bonds, strained to keep her head upright, already heavy and wrapped in burning muscles from mere minutes in this position, strained to stare straight forward when Rarity was pressed up against her, when those thick, springy coils of perfect purple mane bounced against her face and filled her nose with the scent of passion fruit, when Rarity rubbed her hoof soft and sensual along her aching muscles, when Rarity nuzzled along her neck and jaw and ear so close that every breath was flame, and each kiss a searing brand.

Two binder clips floated into Twilight’s vision, shrouded in blue glow. When her breath caught at the sight, Rarity nipped at her ear, eking a low, slow moan from the librarian. Twilight came to her senses, and the clips were nowhere to be seen.

“Remember, darling,” whispered Rarity, “It hurts more when I take them off—”

Twilight squealed from pain, from shock, as the clips crunched down on her sensitive teats.

Rarity nuzzled her. “Mmmnnf. How is that, love?”

Tears ran down velvety purple fur. “H-hurts—”

“Do you want to stop?”

Twilight shook her head, as much as the strict bondage would allow. “N-no, Mistress. Green, green.”

“Okay.” A kiss, just behind the ear. “Then,” a second kiss, a third, “hold out your hooves to the side.”

Twilight lifted her front hooves and held each of them out to the side, the thin twine dangling to the floor. Rarity caught the twine up in her pale blue magelight, lifting the two coils on the floor upwards like charmed cobras. Each strand looped over a pulley above Twilight, and then each loose end wrapped itself in a tight knot around the clamps on her teats.

With a few tugs and magical adjustments, each length of twine formed a taut ‘V’ between the bindings on her front hooves, the pulley above, and the clamps below. Twilight gave her front hooves and experimental tug, and hissed in pain as it yanked the clips on her teats..

Rarity smirked. “The joys of predicament bondage, no? If you drop your forehooves, you’ll feel it in those rather sensitive nipples of yours. Not to mention the work-out you’ll be getting, after all, how often do you use those muscles?” she purred, trailing a hoof over the tense thews in her lover’s withers and shoulders.

Twilight groaned. Her hooves had been suspended for less than a minute, and she could already feel the dull ache that came from carrying a too-heavy burden.

Rarity broke her embrace and dropped to all four hooves. Her silk bag of delights levitated itself onto the dais. Her voice came like sweetened espresso, thick, dark, and syrupy. “And how does that feel, Twilight?”

* * *

Twilight’s stomach was a nervous hole, and she was doing her best to fill it with gin and tonic.

Two tables had been pushed together in the otherwise-empty back room of Berry’s Bar to make room for the Ponyville Omni-Knot Enthusiasts. The air conditioning never seemed to work in the back room, and the day’s late-summer heat made the room sweltering. Pressed as she was shoulder-to-shoulder between a giggly Rarity and a chatty Noteworthy, Twilight felt all the warmer.

Noteworthy. Quilbur Davenport. Roseluck. Lily. Carrot Cake and Cup Cake. Matilda. Mr Rich—”Please, call me Filthy,” he’d said to her as she said hello. Garnet. Thunderlane. Flitter. Pokey Pierce. Cheerilee.

Twilight already knew most of the ponies at the table. She didn’t know if that made things better or worse.

“It’s good to see you here, Twilight,” said Cheerilee over the low chatter and clink of glasses, “We were beginning to wonder where Rarity was hiding you!”

Twilight’s mind went blank, grasping at the normal, socially acceptable response that could keep her floating on these strange seas. She swallowed and took a long gulp of her drink, draining half of the glass and nearly sending a wedge of lemon up her nose. “Haha—” laughter, always good, except for funerals, “—yeah. Um. To tell the truth I’ve been meaning to come along for a while now, but, uh...”

“Your nerves got the better of you every time, huh?” Carrot Cake had his elbows on the table, and grinned sheepishly at her. “You know, I did the exact same thing. Honeybun must have gone to half a dozen meetings on her own before I dipped my hoof in.”

Cup Cake giggled, an errant strand of her hot-pink mane falling across her face. “You haven’t ran for the hills yet, dearie,” she said to Twilight, “That’s always a good sign.”

This time, Twilight actually giggled. “Oh-ho, after two years in Ponyville it takes a lot to send me running. I mean, the only weird thing so far is how... normal everything is.”

“You were expecting more chin-dildos?” asked Cheerilee.

Twilight burst out laughing, and the pit in her stomach seemed to smooth over in an instant. “Y-yeah, something like that. I guess I’m not sure how to act, what’s going too far and what’s being too prudish. Come to think of it, I’d actually be less nervous if everypony was dressed in latex and whipping each other and pretending to be dogs.”

“There’s a time and a place for everything,” said Cheerilee, winking at Twilight. The librarian felt a heat run through her that had nothing to do with the sweltering room. “Don’t worry, Twilight, I’m a teacher and a top. I love rules and explaining rules almost as much as you do, so ask away.”

Her heart buoyed. The table’s collective attention had shifted off her, and Cheerilee was offering advice. She was being thrown a lifeline. A lifeline full of kinky, forbidden knowledge.

Twilight Sparkle did not squander such opportunities. “Okay. So, what’s out of bounds? Like, is there anything ponies don’t do or talk about at a munch?”

“Well, we’re in public, so no indecent exposure. Save that for the play parties,” she said, “Really though, a munch is a social thing. We talk, we drink, we see our friends and make new friends, same as any book club or night out with the girls.”

A playful note crept into Cheerilee’s voice. “That being said, this is a meet-up for kinksters. Sex and BDSM are topics that might show up more than usual. As far as what not to talk about, don’t worry. If there’s a problem with a topic, somepony will let you know and we’ll change the subject. If you have a real problem with a topic, don’t be afraid to let us know. We only like making ponies uncomfortable when they ask us nicely for it.”

Twilight grinned. “Duly noted. All right, then, more questions!”

“Ask away.”

“So, how did you get into kink? Well, that and the Ponyville Omni-Knot Enthusiasts too. And what’s an omni-knot?”

“Y’know, I think Pokey Pierce and the Cakes just added ‘omni’ so that the acronym would spell ‘POKE.’”

“Seriously?”

Cheerilee shrugged, and sipped at her ginger ale and whiskey. “Probably, I haven’t asked. Anyway, I met the kink club about a year before you arrived, I think?”

Cup Cake, who had been half-listening, said, “I think it was the fall of ninety-eight that you joined us.”

“That’s right, I remember. I’d been into kink for longer than that, but—Oh, the nachos are here!”

Three gigantic plates of nachos were piled onto the table by an increasingly drunken Berry Punch. Twilight had seen cart-wheels smaller than these plates, which heaved with corn chips, topped with great mounds of melted cheddar and scoops of sour cream, pico de gallo and hot guacamole.

The chatter of conversation quickly turned to soft crunching and little hums of happiness. Rarity ate a piled-high nacho, and then fussed away the sauce around the sides of her mouth. Twilight looked to her marefriend and looked over to Cheerilee, and they both simply nodded.

Twilight took a chip, and popped it into her mouth. It had just a hint of sour cream, and a long strand of cheese that clung to her lip. Delicious.

She didn’t know why she’d been worried.

* * *

She saw the blindfold, and something quivered between her stomach and her nethers.

Twilight had done each part of sensory deprivation individually, but had not combined them all at once, and not in such strict bondage. After the full kit was in place, she could only change her bonds through bluntly ending the scene. To make changes possible, each piece was applied one-by-one, so that Rarity and Twilight both knew that nothing was wrong.

The blindfold was thick, black cotton shaped like a filled-in figure-of-eight. There were no straps, straps could be such clumsy, inelegant things, thought Rarity, and no matter how much you fussed or how wide she made the blindfold, a glimmer of night would shine in from some angle.

The blindfold pressed onto Twilight’s face, and Rarity floated up a brush and liquid latex. In moments, the cloth was sealed over Twilight’s eyes.

“How is that, my little toy?”

Twilight grunted, her hind-legs cramping from standing upright, her teats throbbing with pain, and her forelegs already tiring and twitching. “P-pitch black, mistress.”

“Very good. I’m about to take away your hearing, and after that I’m going to gag you. To end the scene, flash your horn, and to end the scene when the blocker is in place, simply turn the blocker to dust. I trust you understand, and that I don’t have to explain it again more slowly?”

Twilight nodded. Rarity prodded her with a hoof, sending her teetering against her bonds, making her gasp with pain as the clamps pulled at her teats and her straining muscles went through more stress.

“I’m sorry, I didn’t quite hear you.”

“Mistress! I understand, Mistress!”

“Wonderful.”

The earplugs came next.

They weren’t really earplugs at all. Even the best earplugs couldn’t block all sound out, and headphones filled with white noise seemed so brutish. What Rarity had instead was a very special bottle of eardrops. She slipped the dropper into Twilight’s ear and pushed the viscous liquid in, drip by drip, until it pooled up dark and shiny at the edge of her earhole. A moment later, Rarity had filled Twilight’s other ear.

A shimmer came across Rarity’s horn, and the liquid changed into something that was almost jelly. It sealed thick across Twilight’s eardrum, absorbing and dissipating every vibration that entered.

Twilight’s ears screamed with silence.

She saw nothing, heard nothing, and felt only what her Mistress wished her to feel.

Twilight felt herself wink.

A hoof slipped across her lips, and she obediently opened up.

A ring-gag, this time. It forced her mouth open wide, tongue lolling out, cheeks pulled and jaw stretched. The plastic ring slipped between her teeth, and with a click of the buckle it locked into place. She couldn’t move her head for the ropes suspending her by her mane, and so saliva pooled in her mouth. Soon Twilight Sparkle, scientist, librarian, and Element of Magic, would be drooling over herself.

She might have said something like ‘Glahh,’ but of course she couldn’t hear herself any more.

She felt a soft fetlock trail over her horn, and steeled herself for the plunge to come.

The blocker-ring slipped over her horn, and she nearly destroyed it from the shock alone.

Magic was more than simple spells and incantations to Twilight. She could feel the very aether, hear the echoes of spells being cast halfway across Ponyville, sensed the ebbs and flows of all magic around her both ambient and directed. Between her skill and her knowledge, magic was a second sight.

The blocker ring replaced it with pure nothing.

There was panic, but not terror. Twilight could remove the ring if she wished. Princess Celestia had taught her how to overpower such devices when she was twelve years old. Those had been military-grade blocker rings, not a cheap commercial one like this.

She tried to control her breathing, to will herself calm.

Rarity pushed a hoof between Twilight’s legs, into her soaking wet sex and Twilight squealed and her legs shuddered and gave out and she squealed louder, harder as her weight dragged against her bound mane and felt like it was pulling her scalp off and her forehooves twitched as Rarity rubbed her so softly and the pain melted into the heat that ran through her burned through her made her melt made her forehooves into jelly made them twitch and drop and pull her nipples and make squeals and grunts that she couldn’t hear only feel sex and pain and Rarity and sex and Rarity—

* * *

Twilight laughed so hard that her lungs ached.

She had learned so much over the past few hours. She had learned, for example, that Filthy Rich’s dry humor and comic timing could put many comedians to shame. She had learned that Thunderlane, young, athletic, effortlessly charming, had an arrangement of sorts with Carrot Cake, one which Cup Cake was quite content to watch. She had seen several mares that she’d never even considered romantically in a rather different light, and had little shivers at the thought of Matilda pushing her head downwards between her thighs, or Cup Cake’s teeth on the back of her mane. She had learned of Harness Hang Syndrome, of the importance of garden shears, of recipes for roast squash, and uses both culinary and otherwise for the common cucumber.

The mountains of nachos had dwindled to plains of crumbs. The warm bar air and the strong drink had brought a heavy, sluggish, relaxed feeling over the tables. Twilight now openly leaned against Rarity, rubbing her ear up underneath the white unicorn’s chin as a cat would. Thunderlane was sandwiched between the Cakes, Matilda had perched herself on Filthy Rich’s lap while she whispered into his ear, and at the far end of the tables, Roseluck’s storytelling caught the rapt attention of Quilbur, Lily, and Pokey Pierce. Berry Punch had rang the bell for last orders five minutes ago, and now Cheerilee returned with the final round of drinks.

It had been a wonderful evening, and Twilight Sparkle wished she’d came sooner.

* * *

Rarity played her body like a conductor.

Twilight moaned, hearing nothing, only feeling the vibration as it travelled through her body. Her chin, chest and stomach, all the way down to her teats, were covered in wet trails of saliva, all drooling from the ring gag. She twitched and writhed, run through with so much pain and exhaustion and terror and sheer exhilaration that she couldn’t tell one from the other. The clamps on her nipples thrummed, pulled to-and-fro by every errant shake of her fores, weak from exhaustion. Each drop of pain seemed to cause another twitch, and each twitch brought more pain.

She had been flogged. She had been caned. She had been pleasured with the tip of the cane, and then forced to lick it clean of her juices. She had each nipple clamp removed, the teat suckled and nursed by her Mistress as shock and fire bloomed through newly-bloodened nerves, and then re-clamped. She had a vibrator pushed hard against her slit, held there for so long that a tide of orgasms flowed over her, held until she went slack in her bonds even against the pain in her scalp and in her teats, simply because she couldn’t summon the presence of mind to right herself. She had been buried under an avalanche of pure sensation, and could not tell which way was up.

She whimpered as the clamps were removed once more. This time, a tingle of magic went over them, numbing the worst of the pain, and hooves caressed her fores, gently guiding them down to her sides. With a click, the ring gag came unbuckled and then slipped from between her teeth. Another pulse of magic, and her ears filled with the roar of sound.

“How are you feeling, lover?”

“K-kiss...”

Rarity’s lipped pressed against hers, soft and warm against chapped and trembling. As a peek of tongue slipped inside, more bonds untied themselves. The tension disappeared from her scalp as the rope went slack. The spreader bar clanked to the floor. The blindfold fell away.

Rarity slowly guided her back to all fours, and then to a pile of pillows beyond the dais. Twilight could barely move. There didn’t seem to be a thought in her head, and all sensations paled to the ones she had just experienced. All she could feel was the warmth of pure catharsis.

Rarity fed her water and cuddled her from behind, and all they felt was the purest happiness.

Party

There were chocolate-coated peanuts, of course.

Always a bowl of chocolate-coated peanuts. Along with the lube, the mats, the first-aid kits dotted in sensible places, the towels, the sports bottles full of water and the alcohol-free punch (Don’t Drink and Kink!), every room in Filthy Rich’s guest house sported a big bowl of crunchy chocolate-covered confections. At play parties, a pony spend more time watching than actually playing, so it was good to have something to graze as they watched. There was always plenty to watch, after all.

Rarity idly pushed a hoof-full into her mouth as she watched the scene unfold in front of her. Sat on a plastic-covered couch next to Twilight, she slung a fore around Twilight’s withers and relaxed.

Lily, Roseluck and Carrot Cake were in the middle, watched from every angle by spectators in their seats at the sides of the living room. Carrot Cake panted as he rutted Lily from above, pushing her face-down into the mat, wrapping a hoof around her tail to keep her rump held high. His hips cracked against her ass with every thrust, each crack eking out a squeak or grunt from Lily. Roseluck sat to the side of Lily’s head, playing one hoof through Lily’s cornsilk mane, and her other between her own legs. She whispered insults and faint praise to her submissive friend.

Twilight refilled Rarity’s glass of punch, and then—after asking the scene runner for permission, of course—slipped a purple hoof between Rarity’s thighs, and began to pleasure her Mistress. The white unicorn sighed with contentment as Twilight’s hoof caressed her slick sex.

Roseluck threw the most interesting play parties. Rarity hosted the most luxurious ones. Everypony always learned something new and Cheerilee’s parties. The Cakes’ play parties were the best catered. But Filthy Rich, with his usually-empty guest house, his flexible schedule, and his deep pockets, threw the most frequent parties. If none of the other Enthusiasts had the time or the space to host a party on any given fortnight, Filthy would be there to help.

Carrot Cake bit down on Lily’s ear, hard enough to turn her squeaks and gasps into a hoof-muffled screech. His thrusts slowed, pulling all the way out and pushing in so deep that her hips raised another few inches upwards. Thick, white cream began to leak from Lily’s delicate folds, streaks coating Carrot Cake’s length. At Roseluck’s beckoning, he pulled out and walked around. He took Lily’s mane in hoof, and wiped the slick mixture of juices and semen off his cock. As he walked to a sofa, Roseluck kissed Lily softly, and then called for the next volunteer.

Davenport tapped Thunderlane atop the head, and the pegasus removed his head from his cock with a *pop*. As Davenport moved over to the prone Lily and mounted her once more, Thunderlane shuffled next to Filthy Rich, and at the older stallion’s request, began to lick at his half-hard shaft.

Twilight had taken faster to play parties than she had even to munches, thought Rarity. She had picked up the rules quickly—no touching without permission, always work out exactly what you want with a play partner, always play sober, ask, ask, always ask. She had seen Cup Cake tied to a metal cross and flogged with licorice. She had taken part in an impromptu tickle-fight with Flitter, Matilda, and Pokey Pierce. She had been hogtied by Cranky Doodle while Rarity watched from the side, sipping punch and sitting on Matilda’s face.

Tonight, Rarity, Twilight and Cheerilee had their scene all planned out. They could hardly wait.

Davenport climaxed, pulling out and spraying cum all over Lily’s light-pink rump. Each spurt came thick and heavy, clinging to her sweat-lathered cutie mark, hanging in loose strings over her tail, each spurt followed by another seemingly before the first one finished, spraying under her tail, mixing in with the sweat and juices and Carrot Cake’s drying semen between her legs. He stepped aside as the last of it trickled out, and was quickly replaced by Filthy Rich. Lily moaned as he filled her, and her cries were muffled as Roseluck made her service her.

Rarity was so absorbed in Twilight’s ministrations that she didn’t notice Cheerilee appear beside her. Her lush, pink-on-pink mane was tied back into a loose bun, she wore a plain white blouse, and a paddle hung from a belt around her barrel.

“We’re all set up in the dining room,” she whispered.

Rarity grinned. “Oh, wonderful. We’ll be along in just a moment!”

They waited a while longer, watching Lily stuffed between Roseluck and Filthy, watched while Twilight’s face flushed all the redder and the hoof between Rarity’s legs grew slow and clumsy. Filthy finished just as Rarity drained her punch. He stepped over Lily’s form and stroked his cock an inch above her head. His cum was thinner but simply poured from him, drizzling all over Lily’s mane, her left ear twitching as it was filled and covered, plastering her forehead, running down into her eyes and forcing them shut, dribbling over her nostrils, over her lips, all down to her chin. With a moan of pure humiliation, she lifted her head and suckled the last drops from the tip.

As Roseluck leaned down to whisper tainted praise into Lily’s ear, Rarity and Twilight left for the dining room.

The chairs and tables had been moved elsewhere, and much like the living room, several sofas surrounded mats in the middle. Matilda, Pokey Pierce and Flitter were chatting animatedly on one of the sofas, but the other guests were still elsewhere in the house.

Cheerilee had the equipment already laid out. There was a whiteboard on an easel, covered in simple equations and a large set of data. A thin, red strap-on dildo lay below the whiteboard, next to a trio of bullet vibrators.

Rarity pulled her mane back into a bun, and donned her red-rimmed spectacles. With a few elegant swipes of telekinesis, the strap-on was strapped in place. She looked at Cheerilee, and nodded.

“Well, Twilight,” said Cheerilee, “We’ve already discussed what we’re going to do tonight. Are there any changes you’d like to make before we start?”

Twilight smiled broadly. “Nope!”

“And what are the safewords?”

“Red to stop the scene, yellow for ‘ease off,’ and green for go. We’re not playing nonconsent, so any ‘no’ or ‘stop’ means red.” Twilight was almost dancing on hooftips. “Can we start now? I’m getting kinda antsy.”

“We certainly can,” said Cheerilee. A change swept over her face, from soft and playful to set and stern.

“Twilight Sparkle” said Cheerilee, in her gravest voice, “Are those your data on the whiteboard?”

“Y-yes, Professor Cheerilee.”

“Oh-ho? You’ve been a naughty little undergraduate then, haven’t you, Miss Sparkle?”

Twilight swallowed, her mind slowly switching into the scene. “I d-don’t understand...”

“Describe your data for me, now!” snapped Cheerilee.

“They’re thaum-to-thermal scores for activated malachite across three different conditions, ma’am—” Twilight yelped in shock as Cheerilee slapped her across the face.

“What conditions? Don’t make me waste more time on you than I need to, Miss Sparkle.”

There was a genuine quiver in Twilight’s voice now, and another between her haunches. “V-vibrations at one hundred, one thousand, and ten-thousand hertz.”

Cheerilee was beside Twilight now, close enough to nuzzle her. “And were the means significantly different?”

“Yes, Profess—aaaghh!”

At a nod from Cheerilee, Rarity swung a cane from behind and struck Twilight just under the buttocks. She followed through hard enough to deaden the *thwip* of the cane, surely hard enough to leave a welt. Twilight struggled to stay upright, and she felt the strings in her throat and between her eyes that always twinged before the tears came.

“Listen to me, you slutty little bildungsphilister,” growled Cheerilee, “If you lie to me, I’ll see you sent straight back to ma—”

“Yellow!” cried Twilight.

Cheerilee stepped back, and Rarity let the cane fall to the floor.

“Am I too heavy with the cane, love?” she asked.

“No, just a-ah... Please don’t mention the K-word...” whispered Twilight.

Cheerilee’s eyebrows popped up. “The K-word? What’s—Ohh. Ah. Okay, no K-word.”

“Thanks,” said Twilight. “I’m ready. Green?”

Cheerilee leaned back in, and Rarity ran her hoof over Twilight’s rump. “How did you tell if the differences were significant?” asked the teacher.

“W-with three t-tests, Professor Cheerilee...”

Cheerilee gasped, scandalised. “You used the wrong test! Experimental designs with independent measures, parametric data and more than two conditions require a one-way independent-measures analysis of variance!”

“I’m s-sorry, Professor!”

Cheerilee’s voice came thick and heavy as molten lead. “Oh, but sorry simply won’t cut it, Miss Sparkle. You’ve been fishing for p-values, and that is a deadly scientific sin. You’ll have to prove how sorry you are if you want to stay on this course.”

“Please, I’ll do anything,” said Twilight, imploringly.

Cheerilee nodded again, and Twilight quickly found herself mounted by Rarity. The purple unicorn gasped as the thin strap-on slid inside her, sinking to the hilt in her soaking-wet slit. She shuddered with pleasure. Rarity had a gentle touch and agility to put a cat to shame. The first few fast, fluid flicks of Rarity’s hips already had Twilight’s knees wobbling and ears splaying back.

“Aaahhh—” cried Twilight, as Rarity levitated the three bullet vibrators and pressed them against her, one on each of Twilight’s nipples. Twilight’s whole coat rippled, shudders went through her spine and down her belly and Rarity was biting down on the back of her neck her whole body was so warm against hers and Rarity moved so smoothly Rarity could play her like a cellist each thrust came in and out so smoothly never slamming her never making her wince just the perfect pace to get her close so close—

The vibrators switched off, and Rarity pulled her hips back until only the tip was still inside. Twilight growled with frustration, before a slap from Cheerilee silenced her.

“Your first lesson,” said Cheerilee, “Is that playing with statistical tests gets you nowhere. It will only leave you frustrated when you repeat the experiment and find no significant results. Better that you experience this frustration now than later in your academic career, no?”

Oh, and frustration it was. Rarity’s control was masterful. Again and again she brought Twilight high, each thrust and buzz pushing her further up towards the peak, up to the ledge where the tiniest nudge would send her off, and then brought her straight down. The tailor moved with practiced precision and a skillful economy of movement, so that even as Twilight writhed and moaned and sweated beneath her, only the faintest sheen of perspiration appeared on her coat. She would thrust and hold the vibrators to her lover until the exact moment that Twilight’s eyes rolled back, and suddenly stop. She’d bite and nip and spank her during these respites, pouring hot flashes and chills through Twilight.

After ten minutes, which must have seemed like hours for Twilight, Cheerilee lifted her chin with a hoof. “Are you ready for your next lesson, Miss Sparkle?”

Twilight tried to shake a sweat-soaked strand of mane from her eyes, to no avail. “M-more...”

Cheerilee smirked. “Now’s not the time for begging, Twilight. That comes later.”

Twilight simply whined and tried to push her hips back against Rarity. She got a hard bite on her shoulder for her effort.

“The second lesson,” continued Cheerilee, “is the importance of collaboration. Thunderlane, dear?”

The dark-grey pegasus had been in the room for some time. He walked on to the mat and laid down on his back in front of Twilight. Cheerilee walked around him, caressing his muscular form as she went. With a practiced motion she swung her hinds over Thunderlane, sitting on his belly, facing away from him. She took his thick cock between her hooves and gave it a few idle pumps.

She lifted her hips, held his cock, and then dropped downwards. Thunderlane’s cock bent to the side ever-so-slightly, not quite sinking in to her pink, puffy slit, but after a moment the force and the wetness let it slip inside her, dropping halfway down his length in an instant. They groaned simultaneously as Cheerilee wriggled the rest of the way down.

Cheerilee leaned forward and wrapped a hoof around Twilight’s mane. She pulled the unicorn down between her hinds, splaying them out obscenely so that Twilight was inches away from the cock going in and out of her pussy.

“As—ahh—a researcher,” said Cheerilee, her voice breathy, “you are part of a greater whole. You can often achieve far, mmnn, more knowledge by assisting others with their work. So assist!”

Twilight found herself smooshed between Cheerilee’s thighs. She stuck out her tongue and licked clumsily at the teacher’s folds. The harsh grip on her mane loosened, and turned into gentle petting. Musk filled her nose and made her head swim, sex, sweat, the hint of sunflowers from Cheerilee’s shampoo, the zest from Thunderlane’s bodywash, Cheerilee’s juices, her own juices, Rarity’s juices...

She licked and suckled everything she could reach, trying to ignore the constant cresting-and-troughing as Rarity brought her to the edge only to let her down. She lapped at Cheerilee’s folds, suckled her clit, lapped away the juices that seeped from deep inside Cheerilee and ran down Thunderlane’s shaft, even took Thunderlane’s balls into her mouth, cleaning them of sweat and musk.

Twilight felt no real attraction to stallions, if anything, sex with a stallion grossed her out. But being forced to service one, simply to please one of her Mistresses, debasing herself thus that her other Mistress might give her release? That was a turn-on for the librarian.

Thunderlane began to thrust upwards, his balls hitting Twilight’s lips and chin with every stroke. Cheerilee was content to grind away, moving her thick, lush rump back and forth over his hips. Her white blouse was soaked through with sweat, one of the buttons had popped off, and her bun was shaking loose. Rarity looked in a similar fashion, her spectacles skewed on her nose, sweat visible on her flanks now, her breaths and her thrusts both coming in ragged.

“C’mon Twilight, be a good little student, h-help me cum,” stammered Cheerilee, eyes lidded, practically drunk on sex. She grabbed Twilight by the sides of her head and pulled her forward, then ground the unicorn’s face up against her sex. She wasn’t even using Twilight’s tongue to get her off, Twilight’s nose, lips and chin all rubbed up against her.

Thunderlane and Cheerilee came as one, the pegasus’ entire body tensing as he thrust up one last time, and all tension flowing from Cheerilee’s body as she collapsed backwards onto his chest.

Twilight found her mouth unoccupied. She craned her neck to gaze back at Rarity. “Please...” she whispered.

“With pleasure,” replied her lover.

This time, Rarity did not stop. She did not stop even as the shivers ran through Twilight, did not stop as her legs quivered and her belly twitched, did not stop as Twilight’s cries turned into moans and into stupid, contented mumbling, did not stop as Twilight’s legs gave out and she shuddered, prone, to the floor, did not stop even as Twilight writhed and sparked and muttered high and impossible praises in Rarity’s name.

When Twilight opened her eyes, she was dimly aware of two things.

First, that Rarity had not stopped thrusting. The white unicorn was now indulgently slow, rolling her hips back and forth at a luxurious pace, not dragging Twilight to new heights of pleasure, simply keeping her in a wonderful haze of sensuous heat.

Second, that Cheerilee was sat in front of her, hinds splayed lewdly, grinning down at her. “Are you ready for your third lesson, Twilight?”

Twilight could only nod weakly.

“A good student helps her professor clean up after class...” whispered Cheerilee. She shifted forward, presenting her pussy to Twilight’s face. The lips were pink and slick and puffy, and a hint of white was visible at the bottom.

Twilight pressed her mouth against Cheerilee’s sex, and was rewarded with a flood of rich, salty cream. It spilled into her mouth, over her teeth and tongue, even rising up against her nose as she licked and sucked. She swallowed each mouthful of semen as it came, savoring the hint of Cheerilee’s juices that came with it, and each swallow seemed to bring even more. Cheerilee made little coos as Twilight ate her out.

The four ponies coalesced into a pile of cuddles, and more or less decided that the scene was over. They sipped at water, and Rarity levitated over a bowl of chocolate peanuts. She fed them to her darling Twilight one-by-one, and when they felt like standing, they moved to the sofas.

There was always plenty to watch, after all.
