Lesson Zero
     Thump. Thump. Thump.
     Twilight groaned as she rolled to her back, running a purple hoof through her rumpled mane. She willed her eyes to open just a bit wider, to see past the pounding haze created by the thumping in her head, particularly surrounding her horn. The filly groaned once more in frustration as she pressed both hooves to her forehead in a vain effort to quell the headache.
     Despite the fact of its representation in her cutie mark, even studious Sparkle had to admit that sometimes, magic hurt. The unicorn rolled her eyes. Especially, she thought, when one is forced to drain the last vestiges of magic from their very core of being in an effort to vanquish a furious Ursa Minor.
     The anger bubbling inside Twilight at the thought of the careless colts and the arrogant blue unicorn that had brought the plague upon the town was just barely overshadowed by the dull throb of her head. She characterized the ache as something almost like the pressure of the morning after sharing some heavily fermented cider over at Apple Acres. In spite of herself, Twilight chuckled and made a mental note to drop by the farm more often.
     Suddenly the filly became aware of the gently heaving form curled up next to her. A baby dragon slept soundly under the covers, breathing as evenly as a metronome.
     "Spike?"
     The lump moved slightly and a groggy voice floated from between the sheets. "Twi...5 more minutes..."
     Twilight lifted the edge of the cover to get a look at her number one assistant. "What're you doing in my bed?"
     Realizing he wasn't going to be granted that extra snooze time, Spike crawled from his spot, rubbing his eyes and looking up at the curious unicorn with a yawn. "Oh, nightmare... You don't mind, do you?" Twilight smiled hugely and wrapped her honorary brother in a hug.
     "Oh Spike, of course not, you're always welcome!" Twilight reared back, and Spike finally caught a good glimpse of the filly. Her mane was tangled, her eyes were darkened and tired, and even her colors seemed duller. The dragon was vividly reminded of post-Discord Twilight Sparkle with a shudder.
     "Geez Twilight, you look terrible!" Spike was never really one to dance around his true opinions. Twilight climbed out of bed with a huff.
     "I know. The Ursa yesterday really got to me; my head is killing me." Twilight replied, lifting a hoof again to massage her aching horn. "It's all because of that Trixie and her phony magic..." She crumpled her eyebrows in brooding frustration. A sharp pain of a little splinter lodged in her hoof blitzed through Twilight as she walked to the mirror. "Oh look, I have a little piece of Ponyville stuck in my hoof. Great."
     Spike snorted at the quip, before shuffling toward the door. "Haha, well I think you were amazing. I'm sure Princess Celestia wouldn't mind hearing about that in a little more detail." He paused at the door. "Who knows, maybe she'll have some ideas on how to get back at Trixie!"
     Twilight giggled to herself as she ran a comb through her bangs. The filly knew what Spike mentioned was in jest, but she couldn't shake the lingering thought from her head. Perhaps she would write a followup letter to the princess.
     After all, Trixie had done a bad thing, a very bad thing. Twilight, ever the optimist, believed all ponies could be turned around, and it was just up to her to teach the blue show mare a lesson she'd never forget. Twilight resolved to treat Trixie to a session of what she did best.
     Lecturing.
*~*~*
     Crossing her final letter with a flourish of her quill, Twilight leaned back to admire her work. A beautifully written letter, adressed to Princess Celestia, wrote of the unicorn's final request of the goddess. Celestia seemed impressed by Twilight's description of the Ursa battle and the boastful unicorn, so the purple filly figured it was worth a shot to ask.
     Never one to leave a list checked only once, Twilight began to read her letter aloud.
     "Dear Princess Celestia,
           I am glad you understand what the town went through with Trixie and the Ursa, and I value your support very much. Though I have learned a lot about friendship from the experience, I regret that my findings have not been shared. I believe, however, that every pony can learn a little about friendship from what happened.
          Along those lines, I'd like to request a little time with Trixie at the library, just to talk. Maybe I can get through to her, and it's always worth making a new friend.
                                                          Your faithful student, Twilight Sparkle"
     Satisfied with her work, Twilight bundled the letter in a careful scroll and called for her letter-sending assistant. Promptly, Spike came dashing into the room, wasting no time in sending the scroll to the Princess. Twilight smiled and sat on her haunches, eagerly awaiting a response.
     "So, d'you really think lecturing her is going to work?" Spike asked, joining Twilight in wait.
     "I'm sure of it, Spike." The unicorn affirmed with a confident nod. "Besides, there's no way she can argue with hard logic." Spike shrugged.
     "I dunno, Twilight," he replied, scratching his head, "Trixie's head and your logic seem to share that quality." Twiliht's confident look didn't falter in spite of the dragon's doubts. The purple unicorn opened her mouth in reply, but was interrupted by a jet of green flame and a letter sailing to her hooves.
     She levitated the scroll, crested with a C, and unrolled it with a smug look. "Prompt, as always."
     Spike watched as Twilight's eyes moved along the letter, tracing the words, her smile growing wider and wider like a waxing moon. As she reached the last sentence, the unicorn lit up like a firework on Equestrian Independence Day.
     "Yes, Spike, I knew she'd allow it!" Twilight tucked away the letter and sprung to her hooves, hopping around the stunned dragon like a foal. "Fire up the logic cannons!"
     Spike conjured up a smile, though his eyebrows remained furrowed. The keeper of logic, fact, and reason and the most arrogant pony in Equestria in the same room for a lecturing session: what could go wrong?
*~*~*
     Twilight sat at her desk, poised as ever, scribbling a few last notes in preperation for her lesson with Trixie. She'd been up even earlier than usual, busily spilling ideas for a once-in-a-lifetime lecture. Twilight ensured that if she couldn't crack Trixie's thick skull, nopony could.
     Finishing her last word, the unicorn sat back, her eyes locking on the wall clock, tracking the minute hand along its journey. Trixie was to arrive at noon sharp; she had no other option, under orders of Celestia. For now, Twilight simply watched the clock, feeling as though she was waiting for the gunshot at the start on a marathon. A marathon of learning, that is.
     11:58. 11:58 and a half. 11:59. 11:59 and a half. 11:59 and seven eighths.
     Showtime.
     Years of stage cues had given the unicorn impeccable timing practice; Trixie walked through the library door exactly as the minute hand hit the 12. With a flick of her blue mane, the haughty filly tossed aside her cloak and approached Twilight, who eagerly met her halfway.
     "Hello Trixie, I'm Twilight Sparkle," The purple unicorn began genially, "I know we've met before, I just-"
     She was cut off. "That's nice, Nightlight Sprinkle." Trixie declared, before putting on an angrier tone. "Look, Trixie knows she might not be the most magical in Equestria now, but Trixie is certainly much more great and powerful than any of these other Ponyville ruffians." She continued, with a little snort to prove her point. "Spare Trixie the formalities."
     Twilight persisted, determined as ever. Commence with the lecturing. "Look, Trixie, I'm not here to be the bad guy, okay? Let's just have a seat and chat." With that, Twilight strode off and settled into a nearby chair, beckoning for her guest to take the one adjacent to her.
     "Very well, Trixie can indulge in your game." The light blue mare sat hesistantly in the seat, finding it cushier than she'd expected. She cocked an eyebrow at the purple unicorn, expecting the talking to begin. Twilight could recognize a cue when she saw it.
     "Well, alright, I just wanted to talk a little bit about friendship with you." Twilight began, the smile returning to her face and her teaching mode engaging. "As you may know, Princess Celestia sent me here to Ponyville to learn about-" The unicorn found herself interrupted once more.
     "Trixie does not need to know about friendship, for she is already the best friend a pony could have." Trixie let out a snicker and leaned back in her seat, flicking her mane to the side with a hoof. Twilight, despite her best efforts not to, noticed the enticing position in which the unicorn set herself in.
     "Oh, there's always something to learn!" Twilight countered. "For instance, yesterday with the Ursa Minor, I-" For the third time, Twilight was unable to spit out an entire thought.
     "Oh please, Spylight Tinkle, Trixie was just tired from all of her wonderful magic tricks!" Trixie lit up in a wicked grin, which made Twilight feel slightly hotter under the collar. "In fact, Trixie is certain she can vanquish an Ursa MAJOR right now!" She positively swelled with bravado; Twilight began to expect a set of the show mare's signature fireworks to appear.
     When Twilight didn't immediately reply, Trixie allowed the smirk to widen across her pleasant features, catching her host's eye. Twilight Sparkle couldn't help but notice the soft look of her pale blue coat, the smoldering proud look in her eyes, the long lashes...
     Trixie was pleased with her performance; she was truly an artist. The act of grandeur she donned was perfect to cover up the wanton lust beneath it. Never had the show mare felt such an attraction to another filly, an attraction that first sparked during what should have been a fiasco... There was something so sensual about Twilight, yet so infuriating in her calm ways and largely superior magical prowess.
     Twilight Sparkle swore not to be deterred. "Let's not get a little ahead of ourselves here, what I wanted to say is-" By Celestia, would the interrupting never end? Anger came to a boil inside the filly; she was a patron of words, and it felt like a bubble was growing inside her, threatening to burst at every sentence she was forced to swallow.
     "Ha! Don't make Trixie laugh! Trixie doubts there is anything you can tell her that she doesn't already know!" Trixie let out a cold laugh of mirth, brushing her tail across Twilight's snout in mockery. Twilight lost her cool at the gesture.
     Leaping to her hooves, the purple filly faced her cocky guest, horn first. "Is that so? I doubt that anything can get through your thick skull!" She snarled. Twilight was usually reasonable, well-directed, but if you insult her lectures, insult her knowledge, you're aiming to get what you deserve.
     Trixie reacted immediately, whipping around face to face with the angry purple filly, also tilting her horn foreward, feeling  a mixture of passion and fury ravage her insides. "Why don't you show Trixie what you've got, puny unicorn!"
     An internal fire raged inside Twilight. She'd come to teach Trixie about the joys of friendahip, maybe even leave with a new ally. She was cool, she was collected, and fighting was worlds from what Twilight Sparkle was used to. Making a responsible decision, Twilight allowed the fight to be left where it belonged, maybe with a brash pony like Rainbow Dash. With a sigh to calm herself, Twilight lowered her horn and took a step back.
     Trixie let out another snicker and smirk. "That's what Trixie thought." Twilight's pupils shrunk to the size of pinpricks as her brain sparked to life like a cut wire. That's it.
     With a growl, Twilight launched a jet of violet magic from her horn, which Trixie dodged with a squeal. The curse ricocheted off the wall and smashed into her bookcase, sending several large tomes tumbling with heavy thuds. Trixie looked wide-eyed at the damage, before wheeling around to face a seething Twilight. "Oh, Trixie can play that game."
     A flash of blue burst from her horn, burning the tip of Twilight's tail as she leapt out of the way. Retaliating with a burst of her own magic, Twilight pushed away the little voice of conscience in her brain. For Ponyville, for her friends, this was what Trixie deserved.
     The room was alight with curses of violet and blue, bouncing off of walls, burning off bits of purple and blue fur as they hit. Twilight snarled as she lauched a quick and powerful shield spell, sending forth a bubble of pink magic from the tip of her busy horn. A jet of Trixie's magic crashed against the force field, sending it into a vase in a shower of sparks, which smashed the pottery into a million high velocity shards.
     Twilight casted a sharp jet of magic at Trixie, which was deflected with an even sharper slash of the blue unicorn's horn through the air, followed by a blue jet in response. Curse after curse from either side blazed in the library, among yelps from both battling unicorns, and the sound of wood splintering, glass shattering, and order crumbling.
     With a furious burst of energy, Trixie shot a particularly fast streak of magic, which the ridiculously adept Twilight deflected in a flash. The powerful spell flew across the room, hitting a heavy book squarely in the middle, causing the tome to be promptly and completely incinerated.
     Through upholding a force field, Twilight's eyes narrowed to slits as she watched the ashes of the book get swept up into the chaos. "Memoirs of-argh- Starswirl the Bearded." She grunted in strain. "That-ugh-is IT!" With a frightening cry, Twilight summoned every bit of magical energy into an enormous, intense stream of magic that burst throuh her horn like lava from a volcano.
     The flash of light was met halfway by a thick burst of Trixie's own magic, resulting in an epic collision of magical energy and electricity between the two, setting the room alight in almost rainboom-like proportions. Twilight felt energy pulsing through her veins as her magic once again proved superior, overtaking Trixie's and sending the blue unicorn crashing backwards into a bookshelf.
     Finally the room quieted, leaving only the little noises of a greatly weakened and feebly stirring Trixie slumped in the corner. Twilight strode over to her defeated oponent, glaring down at her, purple chest heaving and horn smoking slightly. Twilight's eyes were burning with the infernos of fury and crazed passion, a lust that existed for reasons she could not fathom. Watching the arrogant unicorn broken before sparked something different in Twilight Sparkle, a kind of power; the purple filly felt more like dragon than pony at that moment.
     Forget lecturing, it wasn't going to work anyhow, Twilight thought to herself. Maybe we'll try a different approach.
     "Finally I have you right where I want you, Trixie." The unicorn spoke, piercing the silence and bearing a wicked grin. Trixie looked up, tired and unsure what to expect. With a bit of strain from her worn out horn, Twilight conjured a binding spell, sending little purple ropes streaming out of the tip. The magical cords snaked around the blue unicorn before her, binding her with little resistance.
     Trixie struggled slightly against the bonds, though to no avail. Regardless, the heat of the battle had left her fiery, and the thought of being bound at the mercy of the attractive mare before her made the show filly damp. Soon the ropes held fast, and Trixie found her hooves unable to move.
     Twilight stepped back, appraising her work. "No, I don't think I got it quite right." With a flicker of magic, she adjusted the ropes, which laced themselves around each of Trixie's hooves. Once each leg was tied individually, the cords latched themselves in four opposite directions to the shelves around her, binding the blue mare in a vertical spread-eagle position. A slight breeze rumpled the fur on her belly, and Trixie realized just how exposed and helpless she was.
     And she did not mind.
     Twilight smiled in approval at the tied mare before her. This meant many things to the purple mare: payback for her town, her friends, her library, teaching a haughty filly a valuable lesson, and fulfilling her most carnal of desires, one that she'd stowed inside her from everypony. Until now.
     Trixie stayed in character; there wasn't a chance in Equestria and Tartarus that she was going to let on how much the bonds excited her, especially not to Twilight Sparkle. "Untie Trixie at once, you brute!" She demanded, straining against the magical binds, "You will regret this, Midnight Snorkle!" Twilight snorted and closed her eyes halfway, gazing at Trixie from under her lashes, biting her lip seductively.
     "Will I?" Twilight leaned foreward even further, almost touching her captive's face with the tip of her snout. Trixie bit back a moan as she felt the purple unicorn's hot, minty breath tickle her nose.
     "Trixie swears it!" Trixie cried, holding to her guns. "Nopony ties up the Geat and Powerful Trix-oh!" For the first time, it was Trixie who was silenced as Twilight placed her lips upon hers in a sensual but fiery kiss that caused flames to lick the inside of Trixie's dripping walls.
     "Oh I hope so," Twilight almost whispered huskily, breaking the kiss but remaining close to Trixie, who was panting. "I want you to make me regret this." She smiled slightly, which sent Trixie's mind whirling.
     Trixie only whimpered as Twilight went back, kissing her first on the lips, before moving down her jawline to her neck. Such a studious filly, yet such a practiced kisser; Trixie couldn't help but wonder where the unicorn had acquired her practice. Wiping the thought from her head, the blue filly immersed herself in the contact, relishing the feeling of Twilight's soft lips upon her. Suddenly, the feeling left.
     "What is this?" Trixie spouted, disappointed. "Trixie demands that you continue!"
     Twilight smirked as an idea flashed through her mind. Trixie was here, vulnerable, but completely into it, while Twilight, the closet freak, was in charge. Oh, yes.
     Without a word, Twilight strode out of the room, clomping up the stairs to her bedroom, leaving Trixie tied and clueless. Trixie sputtered, "Hey! Where are you going, Stinkle?" No reply came, leaving the bewildered unicorn even more confused.
     After a moment of utter confusion on Trixie's part, Twilight returned. A leather riding crop was held fast in her mouth, Trixie's eyes widening at the sight of it. Where would the unicorn even acquire such a thing?
     Twilight practically read her mind. "Gift from my friend Fluttershy. She said it would help me train the mice I turned into horses for the Grand Galloping Gala." Twilight paused in thought. "Never thought it would come in handy like this, though."
     Trixie watched the formidable object as Twilight traced it over her in a haze of purple magic, shivering as it reached her stomach, stopping short at her pelvis, before moving back up. Placing the crop aside, Twilight cast a quick spell that magically flipped Trixie around, so that she now faced the bookshelf, her back to her master.
     Trixie felt a bubble of nervousness swelling up inside her stomach. The feeling of helplessness truly overwhelmed her in the face of another unicorn ready to inflict pain on her tender flesh.
     Of course, no way would she let it show. "Fine, unicorn. Trixie is powerful and can take whatever you give her!" Twilight again traced the crop down her back, eliciting a shudder.
     "Well, in that case..." Thwack. Twilight brought the crop down on Trixie's flank, quite gently really. Trixie let out a cold snicker.
     "Is that all? Please unicorn, that is weak." She regretted it the moment the words left her mouth. Thwack. Thwack. Thwack. The crop hit her flank over and over, each time a little harder, until Trixie began to redden under the fur. In spite of herself and everything she believed in, Trixie couldn't help feeling aroused at the bite of pain that came each time the crop cracked across her flesh. She moaned slightly, feeling the fur around her marehood dampen slightly. Twack. Thwack. However, the pain was getting a little too sharp to bear.
     "Haha, you've had your fun, Trixie says stop it now." Twilight responded with another crack across her backside, harder than the last.
     "I don't think so." Thwack. Twack. Squeal.
     Trixie's flank was really beginning to sting, and her sex was positively dripping, little drops of arousal rolling down her innner thigh. "Okay, stop now, infernal unicorn!"
     Thwack. "Say my name." Twilight was completely immersed in her ministrations, also dripping below. This was far too enjoyable to cut short.
     Thwack. "Thighlight!"
     Thwack. "Moonlight!"
     THWACK. "Sunlight!"
     THWACK! THWACK! "Twilight Sparkle!"
     Twilight smiled to herself as she lowered the crop, which was reared back, ready to strike again. She appraised her cative, who was quivering and whimpering, a small puddle of arousal forming under where she hung. Twilight too was soaked, liquid matting her coat between her legs, sex swollen and glistening.
     She leaned toward Trixie, nibbling gently at her ear, and whispered, "I knew you had it in you."
     Trixie moaned, but switched immediately back to her stage bravado. "Trixie expected more from you, puny Sparkle." Twilight frowned; she'd expected to have broken the haughty unicorn by now. Perhaps more extreme measures were in order.
     Leaving her captive once again, Twilight strode out. She returned in less than a minute, carrying something small that Trixie didn't quite catch a good look at. Twilight settled again behind the unicorn, who still faced the bookshelves.
     "Perhaps..." Twilight whispered, "You may prefer this." She pressed a small object to Trixie's back; cool, flat, and metallic. Trixie's heart began furiously hammering against her ribcage as she came to realize what it was.
     "F-fine, Trixie can take it." She said again, feeling some of her pride dwindle. Twilight persisted, pressing the razor blade harder against Trixie's back, though not hard enough to make a cut.
     "So, you wouldn't mind if I..." Twilight finished her sentence with an increase in pressure, creating the smallest incision, through which a tiny drop of blood began to well. Trixie felt the sharp pain and her eyes widened to the size of dinner plates. No way could she do this.
     "Okay! Trixie gives up! Please don't, Twilight Sparkle!" Trixie squealed, her voice high in fright. "Trixie can't handle it!"
     Twilight could've shot a firework of her own at Trixie's surrender. Operation: Break the Boaster had proved successful, and now Twilight would make sure the real fun could begin.
     With a small burst of violet magic, Twilight once again flipped Trixie to face her. The blue filly appreciated the view of her captor, silently acknowledging how alluring the unicorn looked with her cheeks blushed in lust. Twilight leaned in for a kiss, trailing her lips across Trixie's in the most sensual way possible, whispering, "Good girl."
     Trixie whimpered as Twilight kissed her more deeply, allowing her hoof to run down the side of the unicorn's blue fur. Twilight planted kisses down to Trixie's throat, nipping gently, before moving to place a lick down the blue filly's horn.
     At the stimulation, Trixie moaned loudly; the sensation of Twilight's warm tongue dancing down her horn was too much for her to
handle. Her sex throbbed, begging for attention, nd Trixie strained against the cords, desperately trying to move her front hooves. When they wouldn't budge, the unicorn considered not being able to touch her desperate sex the utmost form of torture.
     Twilight continued her work on Trixie's horn, to the squeals of the latter, before being interrupted by a soft sound. Troxie's fluids dripped to the floor, each time making a quiet pat as they hit the floorboards. Twilight pulled away and almost touched the unicorn with her snout, smiling.
     "Someone's eager." Trixie forgot completely about her performance and nodded her head vigorously. "What would you like me to do?" Twilight asked, though she already knew the answer.
     "Please, just-" Trixie stammered. Twilight leaned into her sex, hovering above it.
     "Just what?"
     "Touch her, Twilight Sparkle, Trixie needs it!" Twilight grinned as she heard what she wanted to. Leaning in, the purple unicorn ran her tongue along Trixie's crevice, eliciting a satisfied sigh from the blue filly.
     Her noises of pleasure sent chills down Twilight's spine, who moaned into Trixie's sex from her own arousal. The purple unicorn looked up at the mare above her as she stiffened her tonngue and located the bundle of nerves at the top. Trixie writhed as Twilight drew circles around her stiff clit, occasionally swiping over the tip of it.
     "Yes, right there, perfect..." Trixie groaned as Twilight continued pleasuring her.
     Changing her technique slightly, Twilight flicked her tongue over Trixie's clitoris in rapid motion. Reaching up a hoof, Twilight circled the outside of her captive's hole. Trixie responded intensely at the new sensations, panting heavily.
    "Aaaah! Trixie's going to... Trixie's going to...mmmpf!" Trixie squealed, teetering on the edge of orgasm before Twilight pulled away. An idea flashed through Twilight's mind, and she ignored the moans of protest from Trixie. "Continue, Twilight Sparkle! Trixie was so close!"
     "Just a moment, Trixie." Twilight said seductively, before strolling out of the room for a third time. Trixie took note of the way her little purple flank swayed from side to side as she went.
     Twilight returned with a covered box, leaving Trixie to wonder with mixed feelings what could be inside. Twilight proved to be kinkier than she could've guessed, so Trixie worried a bit about what formidable treatment may yet be awaiting her.
     Twilight laughed a little and kissed Trixie's forehead. "Don't worry about it." Trixie softened a little bit at Twilight's warm tone, but atiffened back up in arousal when she added, "I'm going to make you come like you never have before."
     Twilight uncovered the box in front of Trixie, revealing an assortment of toys in various shapes and sizes. Among the heap was a strap-on: purple, large, and intimidating. Trixie began to sweat at the sight of it, hoping Twilight wouldn't choose that particular toy to use on her. Her hopes were dashed as the unicorn settled on the strap-on, levitating it away from the rest of the toys.
     "Brand new," Twilight explained gazing admiringly at the giant phallus. "Regrettably, never got to use it." She tapered off, leaving Trixie to wonder who the mare was that she had intended to pound.
     Twilight came back to earth, preparing to fasten on the toy. Trixie swallowed hard and looked at her captor. "T-Trixie doesn't know if that's a good idea." Trixie nervously squeaked. "Trixie doesn't think she can take in all of it."
     Twilight smiled and stroked Trixie's mane tenderly. "I'll be gentle, I promise." The purple filly strapped the toy around her hip and flank, tightening it until she felt the pleasant tingle of the plastic rubbing against her marehood.
     Trixie looked from the large artificial penis bobbing between to pretty unicorn's legs to the unicorn herself, her stomach tightening into a knot. The phallus was large, ridged, and ominous; and soon to be buried deep inside Trixie's own wet marehood.
     The unicorns shared another kiss, as soft as a flower petal, which let the scared unicorn relax slightly, before stiffening up in arousal when Twilight whispered huskily in her ear, "I'm going to make you come harder than you ever have."
     Twilight eased herself against Trixie's trembling form, running her fake penis up and down her slit, coating it with moisture, and drawing a low groan from the bound unicorn. Without further ado, Twilight placed her front hooves on either side of Trixie's head, and with a single, unbroken thrust, buried the toy up to the hilt inside the depths of Trixie's aching sex.
     Trixie cried out, a cry of pain blended with a cry of unmatched pleasure as the toy sent electicity shooting through her marehood as if it were a raw nerve. "Ohhhhh goddessesssss..." She moaned out, burying her face in Twilight's silky purple mane. "What is that?"
     Twilight let out a sigh and replied, "D-Double sensitivity spell." She panted, before adding, "It's effective for both parties." That explained it. Before Twilight even began moving, Trixie felt her loins spark and blaze with a fire she'd never felt before. She shuddered and writhed, grinding her hips frantically against the purple filly, desperate for more contact. Twilight, not to be cruel, obliged her lover's wishes.
     Twilight drew out her hips and plunged them again into Trixie's depths, eliciting a squeal from the blue unicorn as she felt the member bottom out inside her. Twilight thrusted again, and again, each time increasing her pace and strength. The purple filly panted, her head bent foreward, crossing horns with Trixie, who also gave squeals and cries of approval. With each thrust, Twilight felt the hypersensitive strap rub against her hard clit, sending shockwave after shockwave of pleasure through her veins.
     Trixie clenched her inner muscles, hugging the member like a vice, allowing her juices to run down its length as it was forced in and out of her like a piston. She knew she wouldn't last long with the electric rod pounding her, and it was everything the blue mare could do to keep the colorful cursewords that were edging their way out of her mouth back.
     Twilight grunted and gasped as she continued to gyrate her hips, grinding her marehood against the strap. She was close, she knew it, it was only a matter of time. Twiliht felt the mindless swirl of orgasm approaching, and began to slam her hips in and out of Trixie for every bit it was worth.
     With the sudden increase in fervor, Trixie's eyes widened and her pupils dialated and she knew she was done. She was incapable of resisting her lover's merciless assault on her marehood, and with a shrill cry, lost herself in the whirlpool of orgasm. Trixie's muscles clenched repeatedly around the firmly pounding phallus, her brain turning to nothing more than a pile of pleasure saturated mush. At the peak of her climax, Trixie vaguely felt a squirt of liquid leave her throbbing marehood and roll down the length of the plastic member, before splattering onto the floorboards.
     The sight of the involuntarily twitching and moaning mare beneath her, Twilight felt herself also fall over the precipice of orgasm. She screamed into Trixie's mane, and, with a few more thrusts of her hammer of a penis, felt herself release, the product
of her orgasm dripping down her inner thighs. Furiously grinding on the strap of the toy still buried inside Trixie, Twilight rode out her orgasm on a torrent of laa, the same lava that was pulsing through her veins, setting every fiber in her body alight with transcendental pleasure. She leaned against the gasping blue mare, panting and moaning with every squeeze of her internal muscles, both mares enjoying their last vestiges of orgasm.
     As their breathing slowed and relaxation spread over the both of them, Twilight and Trixie, polar oposites and archenemies, reveled in the feeling of simply being in eachother's presence. Trixie broke the silence first.
     "Twilight Sparkle? Could you untie Trixie please?" Twilight gasped as she remembered the vulnerable position she had left the blue unicorn in. With a lick of magic, Trixie fell to her hooves, shaking slightly like a willow as she struggled to stay standing. Looking up at the purple filly, Trixie gave a smile, a real one, an honest smile that was a truly rare sight on the light blue normally arrogant unicorn. Twilight felt her insides melt; maybe she could leave with a new friend after all, maybe even more.
     The delicate exchange between the two former rivals was cut short by a crash the shook the foundations of the library coming from the street. Twilight almost jumped out of her skin in shock, before assuming battle stance.
     Another earthquake of a crash. "What in the name of Celestia is that?!" Twilight cried, ready to bolt out the door, before she was stopped by a shout from Trixie.
     "Wait! Twilight Sparkle, don't be angry with Trixie, but..." Trixie's nerve faltered, causing Twilight to stare at her in shock and suspense.
     "What? What is it?!" Twilight demanded frantically, followed by another crash.
     "T-Trixie may have brought a friend to our meeting..."
     Twilight's pupils shrunk to minscule size as her heart stopped in her throat. "What are you-? Who did you-?" When Trixie didn't immediately answer, Twilight tilted her horn foreward threateningly. "Tell me what or who you brought!"
     "U-Ursa Major."
