She invites Fluttershy and Discord to her castle in order to get a little first hoof experience with the draconequus. But will the study go as planned? And does the princess of friendship have something more planned out for her friends?

A Very Thorough Study

Fluttershy and Discord popped into the foyer of Twilight Sparkles castle, a bright flash of white light the only signal heralding their arrival. All around the entrance-way, boxes of the princess's possessions were neatly arranged based on size, content, and gradient of the cardboard; a poignant reminder for Fluttershy that her friend would soon be moving out of this castle for a far grander palace in Canterlot. Repairs to the damage that Chrysalis, Tirek, and Cozy Glow had caused were soon to be completed, and then Twilight would officially be crowned as the new ruler of Equestria. But that wasn't what she and Discord were here for today, so Fluttershy did her best not to think about it. Twilight had invited them here for some sort of research study, but had been rather vague on the details. Fluttershy was wondering what she could want with them when the Princess of Friendship trotted into the room to greet them, smiling warmly as she approached.

"Thank you both so much for coming here today," Twilight Sparkle spoke as she greeted her friends, "I really appreciate you both agreeing to help me with my research."

"Umm, no problem Twi," Fluttershy said, "though, you weren't really clear on what you needed help with. It's nothing scary, is it?"

"Oh no. Quite the opposite, actually. I suspect you'll find it rather... enjoyable," Twilight said enigmatically.

"Well," Discord huffed, "whatever it is, I hope you appreciate me taking time from my very busy schedule to come here and assist you, my dear princess."

"Aren't you the god of chaos?" Twilight asked. "It seems to me that having any sort of schedule would be rather anathema to you."

"Exactly," Discord said, "and it's preciously because of that it keeps me so busy. It's very demanding to stick to a schedule that doesn't exist."

"I'm sure," Twilight said as she rolled her eyes, "it sounds to me like that just means you have nothing to actually do."

"Have you ever tried to do nothing, princess?" Discord asked. "You'd be surprised how many somethings keep getting in the way."

"Well, I hope this 'something' won't inconvenience you for too long, Discord," Twilight smiled at him, attempting to hide her annoyance with the draconequus as she did so. It was a poor attempt.

"So what is it you need help with, Twilight?" Fluttershy asked, interrupting her two friends. She knew the two of them could keep bickering like this for hours if left to their own devices.

"Oh, right! Well, as you know, since my coronation has been delayed I've been trying to learn more about the non-pony creatures in the realm. After all, if I'm going to be ruler of Equestria, I ought to have an intimate understanding of all the creatures who live in it," Twilight explained, as Fluttershy noted the odd emphasis Twilight had used.

"Anyway," the princess continued, "the one species I have the least information on is Draconequuses, so I thought I should invite the one draconequus I know over so that I could research him. After all, you will be one of my subjects once I'm crowned."

"Ah, I see. So you plan to subject your subject to being a subject for your subject of study?" Discord inquired. "And you expect me to simply subject to your whims? That seems rather presumptuous, my dear princess."

"Well, that's subjective," Twilight responded. "I think you'll find yourself a willing participant once I explain what I'm looking to study."

"What is it?" Fluttershy asked, curious what Twilight had in mind, and how it involved her coming here with Discord.

"I'm looking to study Draconequus mating habits," Twilight stated simply, smiling brightly at her friend and Discord as she said it.

"Oh, I see... Wait! What?" Fluttershy took a moment to register what Twilight had said, surprised she would so blatantly say such a thing.

"I wish to observe the two of you engaging in coitus. You know, having sex?" Twilight clarified, "I mean, from everything Rainbow Dash and Pinkie Pie have told me, the two of you aren't shy about the subject. And it's not as if I've never watched you have sex, Fluttershy. And we've done it together plenty, too. It's what makes you a perfect control for my research," she continued, giddy with excitement at having such a perfect couple to observe, "I've seen you with enough ponies that I'll be able to observe the differences easily when mating with Discord."

"Umm..." Fluttershy was at a loss for words.

"Please, please, please, please," Twilight begged her friend.

"Well, okay. So long as Discord's alright with it," Fluttershy relented.

Twilight's eyes darted to Discord, beaming with an excited smile while pleading with her eyes.

"Well, well Twilight, I never imagined you to have such a voyeuristic streak. But what makes you think I'll go along with this?" Discord asked. "I can have sex with Fluttershy in the comfort of our homes anytime, without nosy princesses watching us."

"I'll let you fuck me afterwards," Twilight stated bluntly.

"Deal," Discord replied immediately, not wanting to lose the chance of Twilight offering herself to him. She was the last alicorn on his to do list, at least until Flurry Heart turned legal, and he wasn't about to turn down such a golden opportunity to cross her name off.

"Great!" Twilight said as her horn began to glow.

Suddenly a magenta flash engulfed the three and they teleported into a sparsely decorated bedroom. A single princess-sized bed was positioned in the middle of the room so that Twilight could watch the action taking place on it from all angles. Windows around the room provided plenty of sunlight to the room, and a single chest sat in the far corner. Discord and Fluttershy had been dropped onto the bed when they were brought to the room, with Twilight now standing beside them on the floor. Fluttershy was positioned so that her rear end was presented to Discord, who had been teleported directly behind her. Twilight was holding a notepad and pen in her magic, ready to start making notations.

"Okay, go ahead you two." she smiled with eager anticipation.

"Umm, what?" Fluttershy asked, trying to get her bearings on the current situation.

"Start having sex," Twilight requested. "Don't worry, I'll be right here taking notes."

"You want us to just start doing it like that?" Discord asked, for once nearly as flustered as his marefriend at a situation.

"Is that a problem?" Twilight asked innocently.

"Well, it's a bit sudden for me to just go at her like this," Discord explained, "I'm not even hard yet."

"Hmm, I see," Twilight's pen was scratching a note down as she spoke, "Interesting."

"What are you writing?" Discord asked with suspicion.

"Oh, just jotting down some notes," Twilight answered casually.

"Let me see that," Discord demanded, snapping his fingers to materialize the notepad in front of him. He read: "Draconequus mating notes - subject has difficulty performing in bed?" his voice rose in disbelief as she read what Twilight had written down. "I most certainly do not!"

"It's perfectly alright, Discord," Twilight spoke calmly, grabbing the notes back. "Lot's of species have problems, ahem, rising to the occasion sometimes."

"Now listen here, Sparkle!" Discord spoke with menace as his face began to scowl.

"Twilight" Fluttershy cut in, placing a wing on her lover's shoulder to calm him, "I assure you that Discord doesn't have any performance problems. Trust me, I would know. It's just that we, you know, usually engage in a little foreplay first before we just start rutting."

"Ah, I see," Twilight said as she continued to take notes, hiding what she was writing from Discord's prying eyes. Even as they floated out of his sockets and tried to sneak around her. "Well, then why don't you do whatever the two of you usually do to get ready."

"Okay..." Fluttershy's voice still had a tinge of anxiety at the whole situation she was in, but she wasn't going to renege on a favor to a friend. "Discord, lay on your back please? Thank you."

With Discord now laying down, leaning back on his elbows so he could watch Fluttershy work, she moved between his legs. She gave his shaft a quick kiss and nuzzle, before dragging her tongue along it's length. Discord began to rise as Fluttershy lapped at his cock, running his clawed hand through his lover's hair as she worked at him. When he had gotten hard enough, she engulfed him with her mouth, earning herself a pleasured moan as Discord felt the wet heat of her mouth surround him. Her tongue worked his shaft as she started to bob her head up and down on him, coating his cock in her saliva and filling the room with the sound of her wet slurping.

Twilight watched her friend work, taking notes on what techniques seemed most effective and how Discord reacted to what she was doing. She also observed that Fluttershy was beginning to get pretty damp herself as she sucked Discord off. After a few minutes of work, she saw that Discord was clenching the sheets of the bed and seemed to be getting close to climax.

"Okay, stop Fluttershy," she ordered, causing the pegasus to suddenly remember she had an audience. She popped the cock out of her mouth and looked questioningly at Twilight.

Twilight had pulled out a measuring tape and moved in to inspect the dimensions of the object before her. Discord and Fluttershy both sat flabbergasted on the bed as they watched her friend manipulate Discord's junk, making note of all his measurements and characteristics. When she had finished, she stepped back and reviewed her notes.

"Interesting." she said after a moment. "Subject's penis is similar in appearance and proportion to a typical stallion. However, it seems to be roughly three standard deviations larger than the average size of an Earth Pony stallion." She leaned over again to run her tongue from the base of the shaft up to the tip. "Penis is slightly saltier than a stallion, and with a stronger umami flavor than is typically present." she paused reciting her notes to look Discord in the eye. She smiled warmly. "Overall, you taste pretty good Discord. I can see why Fluttershy enjoys blowing you so much.

She used her magic to pick the pegasus up and turn her around, then raised her tail up to show off Fluttershy's posterior. "You can observe how wet she's become by simply servicing your member, with no outside stimulation of her own privates." Fluttershy blushed as Twilight's hoof ran along her lips. "Do you see how her labial walls twitch when I touch them? That's another signal that her vagina is ready to receive you." Twilight explained.

She hopped off the bed and looked at the two expectantly. "Okay, you're both ready now. Please proceed with the process of fornication if you would."

Fluttershy looked over her shoulder and glanced up at Discord, who simply shrugged and began to line himself up with her entrance. They both knew how Twilight could get, and figured they should probably just appease her before she began to make more demands.

Discord slid himself inside her, savoring the warm tightness that surrounded him. No matter how many times they did this with each other, Discord never lost his appreciation of how good Fluttershy felt to be inside of. He started to pump himself in and out of her, starting out slow to let her adjust to his size. His movements began to grow quicker and more forceful as he rutted her, the two of them getting more and more into it as they forgot all about Twilight and focused only on each other's bodies. Fluttershy began to thrust herself backwards to meet him as the fucked, shamelessly moaning as they slammed into one another. Having already experienced Fluttershy's excellent blowjob skills, Discord was the first to approach orgasm, feeling he was only a couple thrusts away from firing off inside of her.

"Excellent job, you two," Twilight complemented them as her magic encircled Fluttershy and pulled her off Discord, leaving him distraught as he was once again denied his big climax by the princess.

"What the?" He exclaimed as he realized what had happened.

"Subject's testicles contract prior to insemination, and the tip of the penis flares similar to a pony's when orgasm is imminent." Twilight recited as she wrote down her observations. "Additionally, the subject's shaft appears to expand in thickness by approximately..." Twilight wrapped her tape measure around Discord's member again, "0.58% prior to ejaculation."

"Twilight, do you mind?" Discord's voice intruded on her note taking "I was about to fill my dear little Fluttershy with a rather copious amount of cum when you so rudely pulled her off of me."

"Oh, I'm sorry Discord," Twilight said without a hint of apology in her tone, "Did you forget that his is a research project?" I'm afraid that some pauses are necessary in order to allow me a full examination of each step of the process. Anyway, you may proceed."

Discord realigned himself with Fluttershy and the two picked up from where they had left off. Fluttershy's voice was growing in volume as Discord rutted her, feeling his cock stir her insides as he pounded in and out of her small frame. As she took his pounding cock, she felt her pleasure overflowing until at last she came, clenching down on Discord's cock inside of her as she squirted out onto the bed. The feeling of Fluttershy tightening around him as she climaxed was enough to bring the god of chaos once again to the brink, when suddenly -

"Fluttershy! Fluttershy! Come quick" Rainbow Dash flew full speed through the window calling out her friend's name. "I need your help with a, uhm, a sick animal. Yeah, that's it, a really sick animal of some sort."

Discord could swear he saw the rainbow pegasus wink at Twilight.

"Oh dear Dashie. I'll be right there," Fluttershy said, as the mood between her and Discord was rapidly being murdered by her friend's intrusion. "Let me just finish Discord off and we'll-"

"No time, let's go," Rainbow Dash said as she picked her friend up in her hooves and zipped out of the room, a rainbow streak and the sound of Fluttershy's surprised squeak the only evidence remaining of the two mares' presence.

"Oh for crying out loud!" Discord exclaimed as he was once again interrupted, "Can't a guy cum in a mare without all these constant interruptions?"

"Oh dear," Twilight spoke in a deadpan voice, "what an utterly unexpected interruption and abduction."

"Oh really?" Discord eyed the alicorn suspiciously, "May I ask just how Rainbow Dash knew not only that we were at your castle, but knew exactly which room we'd be in? And why she didn't seem at all surprised by what was happening in here?"

Oh, well," Twilight's eyes darted back and forth, "You know how Rainbow can be. haha..."

Discord cocked an eyebrow and looked quizzically at her.

"Wellll... maybe I just wanted Fluttershy gone before I had by turn with you," Twilight was blushing slightly, and her eyes avoided direct contact with his.

"Well, little Sparkle, if that's all you wanted you could have just asked," he snapped and suddenly he was behind her. He grabbed her tail roughly in his claw and lifted it, tugging her hind quarters a bit off the floor as he inspected her crotch. Smirking at how wet she was, he spanked her ass with his paw and let her drop back to the ground.

"My, my. You are indeed horny for me, aren't you Princess? Well, far be it for me to deny you a first hoof experience with a draconequus dick." Discord teased.

Discord flipped her over onto her back and let his cock plop onto her stomach. Twilight moaned as she felt him grind his cock against her slit, dragging it up and down against her. Her wings splayed out on the mattress as he coated himself with her damp arousal. At last, he slid his dick down her hole and his head slowly began to push her lips open and enter her. He readied himself to push into her, began to slowly ease into her, and then she disappeared in a magenta flash. He thrust a couple more inches into empty air before he realized what happened and looked around for her.

Twilight was standing behind him, smiling and looking to all the world as if she hadn't just been panting beneath him on her back as he slipped his cock inside of her.

"Sorry Discord," she laughed, "but if I'm going to let you inside me, we're doing it on my terms." She floated the chest that had been sitting forgotten in the corner to the side of the bed. She opened the lit to reveal a set of black restraining cuffs. "Put these on, lie down, and attach yourself to the bed. I'm going to ride you and I don't want you grabbing my ass or spanking me or anything while I'm doing it."

Discord contemplated to himself whether this was all worth it. Twilight was obviously trying to play toward something in all this teasing, but he couldn't quite get a feel for what her game was.

His thought's were interrupted as Twilight took him in her hot and damp mouth, and began to work her tongue around him. He grunted in surprise as he felt her take him in. Her technique wasn't quite as refined as Fluttershy's, although he supposed that could be attributed to how often Fluttershy had sucked him off over the years. What Twilight lacked in skill though, she made up for in passion as she slurped his cock down her throat and lapped her tongue around it as if it were the tastiest thing she's ever had in her mouth. Drool and tears began to run down her face as she choked herself on his dick, now properly throat fucking the draconequus with a level of enthusiasm that would put even Pinkie Pie to shame. She sucked him to the very brink of orgasm, and then pulled off just before he could paint her throat with his load.

He groaned in frustration as he was once again denied release. He glared sharply down at the pony princess still standing in front of him. She looked back up at him, smiling back as if his cock hadn't just been jammed down her throat a moment earlier. He was getting sick of this act.

"Tell me why I shouldn't freeze you in place and fuck every hole you have until I've paid you back for all this teasing," he snarled at her.

"What's wrong? Can the god of choas not get off unless he's holding a mare down against her will?" Twilight asked with smug superiority in her voice. "Wait until I tell Fluttershy that her boyfriend threatened to rape me. Whatever will she think of you after that?"

"You can really be a bit of a twat sometimes, you know that Your Highness?" Discord asked.

"Just put on the cuffs and get on the bed if you want any chance of getting inside of that twat, oh mighty god of chaos," Twilight fired back.

Discord sighed in resignation and slipped the cuffs on. Something felt odd about them, but he was too horny and pent up at this point to spare them much thought. Fucking Twilight was quickly seeming like it might not have been worth all this headache in the first place, but it was too late now for regrets. He might as well play along with her and enjoy the ride. He lay back on the bed, arms cuffed to the headboard and cock pointed straight up at the ceiling. Twilight climbed up on top of him and positioned her entrance directly above his rigid shaft.

"Ready for me, Discord?" she asked, rubbing the very tip of his cock against her, making it slick with her arousal as she spoke.

"For the love of me, Twilight, stop being such a cock-tease and just let me inside of you," Discord pleaded in mounting frustration.

"As you wish, my subject," Twilight grinned.

Slowly she lowered herself down onto him, taking his impressive length inside of her. She moaned as she felt him splitting her apart, his girth and length filling her more deeply and fully than any stallion she had taken since becoming an alicorn. She hissed as her body lowered steadily down until their hips met, taking him to the hilt and feeling his balls against her plump rear. She began to raise and lower herself up and down in a painfully slow rhythm as Discord pulled at his restraints, wanting to grab this pony by her flanks and just fuck her for all she was worth before pumping his long overdue load inside of her. Twilight began to increase her tempo as her arousal threatened to override her senses. Her speed increased as she fucked herself more forcefully on his length, impaling herself over and over again, moaning and panting in wanton lust as they both approached their peak.

"Oh god, Discord. If I knew you'd feel this good inside of me, I'd have let you fuck me ages ago," she gasped.

She kept up the pace she was going, feeling his balls begin to clench beneath her ass as she slammed herself down on him. As she rose up his shaft, she could feel him swelling as his body prepared to fire its seed off inside of her. She reached the apex of her ascent up his his shaft, only the very tip of him still remaining inside of her. She looked him straight in the eyes as he waited for her to slam herself down again, allowing him to flood her alicorn womb with his cum. He waited.

And waited.

And waited.

And waited as his eyes plead with her to finish him off, and an evil glint flashed across her eyes in response. He tried to voice his pleas, but suddenly her mouth was on his, kissing him with a passion Fluttershy only reached at her most horny. Twilight's tongue forced its way inside his mouth and explored him, mingling against his own as he returned the kiss, too shocked by the sudden intrusion to resist. The alicorn's rear remained stationary, Discord's dick just barely held within as she felt his swelling recede. His semen had once again been denied a chance to escape the confines of his increasingly swollen balls. Discord shivered with a sudden chill as the mare's juices coating his dick were exposed to the air.

Once Twilight was certain that he had calmed down, she lowered herself again, shuddering as she took him back inside herself. She broke the kiss, giving him one last quick peck on the nose, before sitting straight up and riding his cock hard and fast.

"Twilight," Discord groaned "I'm warning you right now that if you don't let me cum this time, I'm taking control of this little interlude."

Twilight didn't even acknowledge that she heard him as she lost herself in the pleasure his dick was providing. Discord had to admit, even as he grew increasingly frustrated with the princess, that she did look beautiful as she rode him. Her head was thrown back as her disheveled mane flopped around behind her, her outstretched wings bouncing along with her as she fucked him, her tongue hanging out of her mouth as her eyes rolled back into her skull. She certainly looked like she was enjoying herself. At last she came, her climax sending her spasming on top of his dick. She fell forward, continuing to fuck him as she kissed him again and accepted his tongue inside of her mouth.

Discord's hips began to buck up to meet hers as he felt his orgasm begin to creep back up again. His and Twilight's tongues swapped between mouths as they rubbed and licked against one another. He felt certain that she would at last allow him to reach release. He was so close as her heat rubbed against him, engulfing him over and over. He was very nearly there. He moaned into the princesses mouth, so very close to pumping her full with his sperm.

And then she stopped.

She stopped and pulled off of him, hopping off the bed as he stared at her in disbelief.

"Well, that was fun," she said appreciatively. "Thanks for helping me out with my research, but I really do have quite a bit more to do today. Unlike some creatures, I actually happen to keep a rather tightly packed schedule."

Discord's disbelief turned to anger as he growled, "Oh no you don't, Twilight. I don't know what kind of game you think you're playing, but I'm finishing inside of you whether you want me to or not. I've had enough of this farce." He snapped his fingers, intending to bring her right back on top of his painfully throbbing erection.

His anger turned right back to disbelief as nothing happened. He stared at his own claws as he snapped them again, still with no result. He tried to teleport off the bed, but found himself unable to do so. He looked over to Twilight for an explanation. Twilight grinned evilly back toward him as he tried to discover the source of his sudden incontinence.

"Oh, I may have forgotten to mention that those cuffs are made from the remnants of Chrysalis's old throne," she smiled, "but don't worry, I'm sure Fluttershy will be back at some point to let you go. Though knowing how her and Rainbow can get when they're heated, I probably wouldn't expect her back until morning at the earliest. You know how those two are."

She began to walk away again. Discord was fighting against his restraints, desperate to be released as he desperately craved some relief. He had been brought to the edge too many times today, and now his balls were throbbing uncomfortably from being so backed up.

"Twilight!" he called after her, pleading to be let go, "Twilight, please let me go. Come now, Your Highness, show some mercy."

"Sorry Discord," she said as she began to move back towards him, "just consider this a friendship lesson."

"What possible lesson am I supposed to learn from all this?" he begged.

"Oh, it's an easy one," Twilight smiled as her face now hovered directly in front of his. "DON'T. RESURRECT. MY. ENEMIES. TO. FUCK. WITH. ME."

Realization and understanding crept across Discord's face as he pieced together Twilight's whole ploy to take some revenge on him.

"Have a good night Discord. I'm sure you'll have plenty of time to think about your actions and reflect on how you can be a better friend in the future." Twilight said. "If it's any consolation, you really did feel rather nice inside of me. Maybe we can do this again for real sometime."

With that, Twilight teleported away, leaving Discord to contemplate his actions alone as the setting sun stole the remaining light from the room. Discord lay in the darkness horny, alone, and reluctantly impressed with how devious Twilight's scheme had been.

"Well played, princess," he thought to himself, "I suppose you really are ready to be a proper ruler."

Author's Note

Twilight deserves a little revenge for the crap Discord put her through, so I figured I'd write her getting a bit for herself.

Hope you enjoyed the read.
