“I-I’m sorry. I… I don’t know what came over me, I just-”
“Twilight Sparkle,” Trixie said in an authoritative tone, silencing the apologising mare standing before her. “This is totally unacceptable. When the Great and Powerful Trixie gives her students an assignment, she excepts it to be done, on time.”
Twilight lowered her head and nodded. “I’m sorry…”
“Now, what are we going to do with you?” Trixie asked, circling Twilight and grinning menacingly. “You know that you need to be punished for this.”
Twilight shuddered, and looked at her ‘teacher’ nervously. “W-What did you have in mind?”
Trixie’s grin grew even larger, and she stopped her circling to bring her face closer to Twilight’s, to the point where their muzzles met. “For this, there’s only one punishment that Trixie can think of.”
Twilight took a step back. “No… you don’t mean-”
Trixie nodded, still grinning for a second… before that grin fell into a frown. A bored, uninterested frown. She almost stopped herself to double-check that this whole thing was what Twilight really wanted, but the smile starting to form on Twilight’s face gave her her answer. “… Lines,” she said flatly.
Almost immediately, Twilight let out a squeal of half protest, staying in character, and half delight, momentarily breaking out of character. “Nooooo!”
“I am the teacher here, young lady!” Trixie shouted, silencing Twilight’s protests. She turned around and used her magic to bring over a lined sheet of A4 paper. “Trixie wants you to fill both sides with: ‘I will hand in all assignments on time’. And you will not leave until you are done. Is that understood?”
Twilight nodded quickly, trying to maintain her saddened student persona, but clearly having trouble, from the way her lips would keep curling into a smile, and then back into a frown as she caught herself.
The purple mare grabbed the paper, and turned around to place it on the table the table behind her. She sat down, and began her work, starting off by neatly writing her name at the top.
Trixie sighed, and walked around her partner to give her a concerned look. “Twilight, are you sure that this is what you want to do?”
Twilight nodded. “Yes! At school, I always strove to be perfect. You know that, right?” Trixie nodded. “But, secretly…” A blush formed on Twilight’s face. “Secretly, I always had fantasies about… being late for class… or doing a terrible job on my homework, or not even handing it in at all!” Twilight’s face exploded into a crimson mess, which she quickly hid behind her hooves.
Trixie shook her head at the sight, but couldn’t help giggling anyway. ‘Only you would get turned on by such thoughts…’ With a final, reluctant sigh, Trixie nodded her head, and continued their role-playing activity. “Very well. I suggest you stop dawdling, young lady. Lest you remain here all night.”
Twilight nodded, and quickly began working on her punishment. “I’ve never done lines before! Oh, this is so exciting!”
“Did Trixie say you could talk?” Trixie asked, arching an eyebrow. Twilight caught her slipup, and quickly apologised, before continuing her assignment. Trixie watched her for all of two seconds, before she couldn’t take it anymore. ‘Buck it. I’m the teacher here, I think I’ll spice things up a bit. Show this egghead what a good time really is.’
Trixie slowly trotted over to where Twilight was sitting, brushing her tail gently across the other mare’s face as she passed her, eliciting a yelp and a blush in response. Grinning victoriously, Trixie circled Twilight so that she was standing right behind her. She fell down to her haunches, and wrapped her forelegs around the busy mare.
“T-Trixie?”
“I beg your pardon?” Trixie said. “Is that how you address your teacher?”
Twilight cursed herself mentally, and quickly corrected herself. “I mean, Miss Lulamoon.” Trixie nodded her approval, and began to gently rub her forehooves up and down Twilight’s chest. “W-What are you doing?”
“This is part of your punishment,” Trixie said, bringing a curious look to Twilight’s face. “Don’t mind me. You just continue to write your lines. And the Great and Powerful Trixie expects them to be done neat, is that understood?” Twilight nodded, but Trixie wasn’t done yet. “If I find even one letter above or below the line, then it’s the ‘special punishment’ for you.”
Twilight gulped, and nodded once again, her heart pounding in her chest. She turned back to her paper, and brought her quill down to continue writing, but had to stop and pull it back up as she felt the mare behind her plant a kiss on her neck, followed quickly by another one, and another. Each kiss was accompanied by a hoof inching lower down her chest, until both hooves were at her stomach, then her hips, and then…
“I don’t see you writing,” Trixie said, interrupting her attacks on Twilight’s neck to remind her ‘student’ of her punishment. “Do I need to send you to the principal’s office?”
Twilight gasped, and quickly shook her head. Even if it wasn’t real, even the thought of such a thing was too much for her! She was willing to play the naughty student role, but being sent to the principal’s office? Everypony had their limits! Even those into bondage had their limits on how much pain they could take. That’s why safe words existed, after all. ‘Maybe I should have come up with a safe word before we started,’ Twilight thought to herself, before bringing her quill back down to her paper.
Trixie laughed mischievously, and brought her lips back to Twilight’s neck… but did not start kissing, as the other mare had hoped. Instead, she moved down Twilight’s body, breathing hot breath onto her coat, causing her to shudder. Despite this, Twilight’s work remained neat. It even remained neat when Trixie found one of Twilight’s extended wings, and gently began to nibble on it. Though Twilight’s breathing had increased drastically, and she was somewhat distracted by the puddle forming on the floor between her legs, she still managed to keep her hoofwriting neat, tidy, and on the lines.
“Twilight, you know the rules,” Trixie said as she glided a hoof down to Twilight’s nether regions. “No food in class. No drinks in class.”
“I-I don’t have any-” Twilight started, but stopped to yelp as Trixie began to bury her hoof inside her lower lips.
“Oh? Then what’s this?” Trixie asked, bringing her wet hoof up to Twilight’s face. “If this isn’t a drink, then what is it? Where did it come from?”
Twilight’s bit her lower lip, and continued to write her lines. “Twilight Sparkle, the Great and Powerful Trixie asked you a question. Where did this fluid come from?”
Twilight closed her eyes, and stopped her writing to answer. “I-It came from… from me…”
“From you? You’ve been drooling in class?” Twilight shook her head. “Crying?” She shook her head again. “… Peeing?”
“I-It’s because you’re making me excited!” Twilight shouted, blushing furiously.
A giggle escaped Trixie’s lips, but she quickly righted herself. “I am? How so?”
“… Y-You’re biting my wing,” Twilight said, and then yelped as she felt Trixie’s hoof back against her lower lips. “A-And you keep… touching me in that way…”
“In what way, Twilight?” Trixie teased, bringing her mouth to Twilight’s ear.
“D-Down there…” Trixie nibbled the tip of Twilight’s ear, and began to move her hoof slowly. “You keep… rubbing me…”
“Where is Trixie rubbing you?” Trixie asked, her hot breath against Twilight’s ear causing the other mare to shudder.
“… Down there,” Twilight repeated.
“You’ll have to be more specific, Twilight.”
“… M-My marehood,” Twilight said, her face growing hotter as the word escaped her mouth. She felt a tongue against her cheek, and she let out a quiet moan.
“Well, that one word for it. But what is it’s actual name, Twilight?” Twilight refused to answer, and Trixie stopped moving her hoof. “Come on. Surely my number one student, knows what this place is called.”
Twilight grit her teeth in frustration as she felt Trixie’s teasing stop suddenly, and wanted to demand that she continue. But she knew she couldn’t. She was a student, and Trixie was her teacher. And her teacher had just asked her a question! As a good student, she had to answer, no matter how embarrassing it was. “… M-My vagin… a.” Twilight said, her eyes clenched shut tightly the whole time.
“That’s correct,” Trixie said, and then resumed her teasing. “I think you deserve a reward for that, don’t you?” Without giving Twilight a chance to answer, Trixie moved her other hoof down to Twilight’s clit, and began to work her hooves in unison together.
Twilight moaned and panted as Trixie’s hooves picked up the pace, and it took all the focus that she had not to drop the quill being held in her magic. When she felt Trixie’s teeth on her sensitive wing once more, it was simply too much to handle. A wave of pleasure passed over her, and she screamed as came in Trixie’s hooves.
Trixie allowed Twilight a moment to settle down, holding the panting mare close and planting soft, gentle kisses across her neck as she waited. When it seemed that Twilight had finally regained her composure, Trixie released her, and stood up. “Twilight Sparkle?”
Twilight turned her head to look at Trixie. “Y-Yes, Miss Lulamoon?”
“What is that?” Trixie asked, pointing at the paper in front of Twilight. Twilight turned to look at it. “Is that what you call neat?”
Twilight would have been apologising for the long, squiggly line running down her paper, but Trixie wasn’t finished yet. “Furthermore, you seem to have made a mess in my classroom.”
Twilight gasped, and quickly rose to her hooves, stumbling over a little bit from the dizziness resulting from the aftermath of her orgasm moments ago. “I-I’m sorry, Miss Lulamoon! I’ll clean it up right away!”
Twilight tried to turn around, but Trixie stopped her by placing a hoof on her shoulder. “I’m sorry, whose classroom is this?”
Twilight hesitated for a second. “Y-Yours, Miss Lulamoon.”
Trixie smiled, and leaned forward to plant a kiss on Twilight’s cheek. “That’s correct. And that means that Trixie will make the rules. Okay?” Twilight nodded. “Now then, I believe the Great and Powerful Trixie warned you what would happen if your work wasn’t neat?”
“… A… special punishment,” Twilight said, shuffling her hooves nervously on the floor.
“Good memory. But don’t think that’ll get you out of this.” Trixie motioned to table beside her. “I want you to lay down on your front on that table.”
Twilight titled her head in confusion, but didn’t question the order. Trixie was her teacher, and she was a student that had misbehaved in her classroom. Refusing the punishment would only land her in deeper trouble than she was already in.
So Twilight simply nodded, and complied with Trixie’s order. “Good,” Trixie said, admiring Twilight’s flanks for a second, before using her magic to lift Twilight’s tail. Twilight almost protested, but managed to stop herself. She felt so embarrassed having herself on full display like this, yet at the same time, it felt exciting.
“Keep your tail up like that,” Trixie said as she released her magic. The tail began to fall for a second, but Twilight immediately caught it, and kept it raised, as instructed. “Trixie will be right back. Do not move.”
Twilight nodded, and waited with anticipation as Trixie walked up the stairs to the upper floor of the library. As she waited, and heard the sounds of clattering upstairs (something told Twilight that some reorganizing will need to be done later), Twilight couldn’t help but wonder what her ‘teacher’ had in store for her.
So many possibilities passed through Twilight’s mind. Some made her even more excited than she already was, and some made her wish Trixie would stop taking her sweet time doing whatever it was that she was doing. Other thoughts made her nervous, and some even made her think that, maybe she should, right now. She pushed those thoughts aside, though. Sure, Trixie could get carried away, but Twilight trusted her. Twilight was sure that Trixie wouldn’t do anything she wouldn’t like, or at the very least, she’d catch on and stop right away.
“Good. You followed my instructions quite well,” Trixie said as she descended the stairs. “Keep this up, and you’ll be out of here very soon.”
Twilight wanted to turn her head to see what Trixie was doing, but she hadn’t been given permission to lift herself up from the table yet. She felt herself growing more wet as Trixie approached, and she was doing everything in her power not to bring a hoof down to her aching marehood.
“Looks like foreplay won’t be necessary,” Trixie said, before touching something against Twilight’s lower lips. It wasn’t her hoof, or her tongue, or her horn, or any part of Trixie’s body. It was something else that Twilight had recognised, and her breath caught as Trixie gently teased it against her entrance.
“M-Miss Lulamoon-”
“Here I come, Twilight,” Trixie said as she climbed on top of Twilight, pinning her down and gently pushing the tip of her strap-on inside the mare beneath her. Twilight cried out as she felt the large thing easing its way inside of her, and then whimpered in protest as she felt it stop. “I love you, Twilight,” Trixie whispered, before thrusting the entire length of her shaft into her mare.
Twilight’s cries grew louder as she suddenly felt herself being filled up by the mare she loved, and moaned when she felt Trixie pulling out. When only the tip remained inside Twilight, Trixie thrust forward again, filling her up once more. This continued for several minutes, each thrust making Twilight’s moans grow louder. Whenever Twilight reached the edge, Trixie stopped her thrusting for a bit, keeping Twilight form cumming without her.
Trixie eventually felt herself drawing close, and decided to the give the pleading mare beneath her exactly what she wanted. She reached a forehoof forward, and forced Twilight to turn her head to face her, so that she could lean forward and plant a kiss on the mare’s lips.
Twilight returned the kiss with just as much hungry lust as Trixie, and opened her lips when she felt the other mare’s tongue brushing against them. Twilight’s wings began to flap wildly as she once again drew near, but this time, Trixie’s thrusting didn’t stop. Quite the opposite; she sped up, intent on making Twilight cum soon.
The two pulled their lips away from each other, and began to cry out in unison as they neared the end, Twilight thrusting her hips against Trixie’s in a rhythm that brought about maximum pleasure for the two mares.
“T-Trixie, I’m gonna… gonna…” Trixie smacked her lips against Twilight’s once more, and both mares screamed into each other’s mouth as they reach orgasm together. Trixie continued to move her hips the entire time, whilst Twilight had to use all of her strength not to buckle down and collapse from the intense pleasure coursing through her body.
After a while, Trixie finally had to stop in order to catch her breath. She pulled out of Twilight, and lay down beside her on the table. Twilight moved to the side to make room, and wrapped her wing around her marefriend, allowing the two of them to cuddle closely together.
“… So,” Trixie began, after recovering and managing to compose herself. Twilight turned to face her, and saw the grin plastered on the mare’s face. “I trust we’ll have no more trouble with late assignments?”
Twilight smiled, and took a moment to re-enter her role as ‘student’. “No, ma’am,” she said, before grinning back at Trixie. The grin was more mischievous, though, and her eyelids were half-lidded as she continued. “No more late assignments, ‘cause I’m not going to hand in assignments at all,” she said in a sultry tone, bringing her muzzle closer to Trixie’s.
Trixie’s eyes widened, and she stared at Twilight in shock for a moment, before resuming her grin. “Oh my. Looks like somepony still hasn’t learned her lesson.” Twilight moved even closer to Trixie, but the blue mare simply pushed herself to her hooves, and began to walk away. “Well then, I guess you leave me no choice.”
Twilight lifted herself to her haunches, and gave Trixie a confused look. “W-What are you going to do?” she asked, genuinely confused as she saw Trixie levitate a quill and a piece of parchment.
“The Great and Powerful Trixie is going to have to write a letter to your parents,” she said, almost giggling as she saw the shocked look on Twilight’s face.
“N-No! You can’t-”
“I can, and I will!” Trixie declared, bringing the quill to the parchment. “You have been naughty, Twilight Sparkle. And as your teacher, it is my job to make sure that your parents are informed of this!”
Twilight could only watch in horror as the quill began to move against the parchment. She knew it was only pretend, but still, the idea of her parents receiving a letter from school, for her bad behaviour, as opposed to good?
‘They’ll know I handed in an assignment late!’ Twilight’s nether regions began to grow tight. ‘They’ll know I didn’t do the punishment I was assigned!’ She felt like she was on fire. ‘They’ll know I disobeyed my teacher! They’ll know I misbehaved, and they’ll scold me! They’ll send me to my room without dinner! They’ll… They’ll…’
Twilight let out a yelp, and shook on the spot as a familiar feeling passed through her body. After she was finished, she looked up at Trixie with an embarrassed look on her face, panting heavily. Trixie simply stared back in disbelief.
“… Twilight?”
“… Y-Yeah?”
“Did you just-”
“… Y-Yeah…”
An awkward silence passed between the two for what felt like decades. Finally, Trixie sought to break it. She placed the quill and the parchment down, and faced away from Twilight. “… Twilight,” she repeated. “Can we just stop this, and go back to regular sex please?”
Twilight quickly nodded her head. “Y-Yeah. That sounds like a good plan.”
Author's Note
Well, here it is, as requested by some people on that one TrixDash fic I wrote not too long ago. I have this idea that Twilight has fantasies about being a bad student in school... and of course, her idea of a bad student is one assignment handed in late, or not calling a teacher by their title, or just being a minute late to class.
Oh Twilie, why you so adorkable?
