Different Kinds of Love

"Twilight!"

Swap looked up immediately at the sound of her disguise's name. She was nearing the top of the hill she'd been climbing and the five ponies on top had just taken notice of her. "Hello."

The pink one-Pinkie Pie-bounded up to her. "I'm so glad you managed to show up! I was worried for a moment that you'd forgotten again because you were already half an hour late but here you are!"

"Here I am," Swap agreed, a little nervously. It taken her way too long, but at least she'd managed to find the picnic spot this time. She could feel Twilight's friends radiating a warm, friendly love for her and smiled at the taste. She looked over the other ponies, her preparation for the mission allowing her to match names to faces.

"Took you quite a while there, Sugarcube," Applejack noted with a tip of her hat to signify a greeting.

"Oh... yeah. Sorry, I just got a little tied up is all."

"It okay," a hovering pegasus-Rainbow Dash- declared. "It's not like we're having this picnic specifically so you could be here or anything. Oh wait..."

"Rainbow, don't be rude," Rarity huffily demanded.

"Sorry."

"No, no, it's okay." Swap took a seat between Fluttershy and Pinkie. "I am pretty late."

Pinkie grinned and deposited a blue-iced cupcake in front of her. "Well, better late than never I always say. Dig in!"

"Uh..." Swap eyed the cupcake before her. Changelings and solid food didn't exactly mix well. Swap had first-hoof experience with this, vividly calling to mind the time she spent puking in a public bathroom on one of her first excursion out of the hive. "M-maybe later."

Pinkie cocked her head, confused. "What? But it's chocolate! Your favorite!"

"I uh... thanks, Pinkie Pie. I'm just not feeling very hungry right now." Swap did her best not to wrinkle her nose at the treat before her.

Nevertheless, she could feel a change in emotions. Everypony felt a little confused by her action, though the most concerning one was Pinkie Pie. Swap didn't need to be able to taste emotions to know that she was suspicious. Between the narrowed eyelids, chin scratching, and hoof-tapping, Pinkie Pie didn't leave much room to the imagination.

Dang it. I should've just stomached the thing. Swap wanted to slap herself. Pinkie had already almost found her out once, maybe. She couldn't afford to keep giving these ponies reasons to suspect she wasn't Twilight.

...I really hope this assignment ends soon.

Miles away, the real Twilight bit down on her pacifier, furrowing her brows in confusion. She turned her head back to look at the rows of desks lining the room back to the replica of her teacher. Chrysalis was looking down on her with Celestia's disappointed face on, which honestly made Twilight feel more nervous than she already was.

Outside of nervousness, she didn't know really what to feel. Anger that Chrysalis had taken her mentor's form? Scared at the prospect of what this could mean? Aroused? In the end, she went with confused.

"W-wha?"

Chrysalis frowned at her. "Yes, you're late. And by a whole ten minutes to boot. And here I thought my most punctual student would be able to show up to her own detention on time."

Twilight bit down on her pacifier, trying to figure out the situation. Chrysalis had said she had a present to give to her. How was turning into Celestia and pretending this was a classroom for detention... wait a second.

Pretending... of course! The other day, Chrysalis had donned a Cadance disguise and pretended to be her old foalsitter. She'd even called it role-playing. Clearly, Chrysalis meant for this to also be a role-playing experience, but possibly one of a more... lude nature. She was pretending to be Celestia after all, somepony she'd already gotten Twilight to show interest in.

Twilight swallowed as she looked up at the commanding face of her mentor, feeling her marehood quiver against her padding. As much as she didn't want to admit it, she was showing interest again.

Chrysalis leaned in, keeping a smirk on Celestia's face. "I suppose the only proper punishment for such a naughty filly is a spanking," she whispered into Twilight's ear. "One for every minute you were late."

Twilight's face exploded red.

With a flick of magic, the straps securing Twilight to her stroller undid themselves and flew off. Twilight slid free and plopped onto the ground diapered rump first, blush not fading.

"And you aren't even wearing your school uniform!" Chrysalis practically yelled. She tsked disappointedly. "Just shameful. I'll have to add ten more spankings to your total."

Twilight blinked. A school uniform? But I've never had one of those before...

Before she could finish the thought, Chrysalis levitated something in front of her. "You're incredibly lucky that I happen to have a spare on hoof."

Twilight eyes widened as she saw the clothes before her. Wrapped in Chrysalis' green aura was a white blouse, exceedingly short plaid skirt, four frilly white stalkings, and some black Mare-y Jane shoes. It was the epitome of a kinky school filly outfit.

The first thought to pass through Twilight's mind was: So that's what the guard gave her.

The second thought was: Does she actually expect me to wear that?

She was lifted off the ground by magic not a moment later, the clothes moving toward her. Well I guess that answers that question.

The clothes gave her a weird feeling in her stomach, almost like it was cramping up. However, because she couldn't do anything about it, she just let herself be dressed.

Chrysalis started by fitting the blouse around Twilight and buttoning it up to the base of her neck. The puffed sleeves hung loosely at her shoulders, but the rest of the garment hugged her body tightly, eventuating her curves. Next up was the plaid skirt, which snaked up her legs and barely squeezed passed her diapered bottom. It was so short, that it didn't even cover a fraction of the white padding. If anything, it called more attention to it than it took away.

Next up was the stockings, which were delicately put on and run up Twilight's legs. She shivered as the silk lightly grazed her fur, biting on her pacifier to calm down a little. Lastly, the shoes were clasped on.

As Twilight was lowered back down, she found herself wishing she had a mirror. As embarrassing as this attire would look on her at pretty much any other time, here she was curious to see just how much of a cute and kinky schoolfilly she made.

However, she was unable to ponder that any further as Twilight found herself being draped across Chrysalis' lap. She looked up, confused for a moment. Chrysalis' hoof snaked up Twilight's backside and she could feel the fake Celestia's fur brush against her stocking. Twilight shivered with delight, which gave Chrysalis a wry smile.

"Now then," Chrysalis said with the infinite calm of Celestia's voice. "I believe it was twenty spanks that I promised you?"

Twilight paled a little, feeling her heart beat faster. She hadn't actually expected Chrysalis to take that seriously. "Uh... maybe...?"

She got a coy grin in return. "I'm pretty sure I did." She gripped Twilight's diaper and started slowly pulling it down, exposing her bare butt to the cold air. She lifted Twilight's tail up and pressed it against her back, leaving her bottom defenseless.

Twilight wiggled slightly, feeling her marehood quiver at the potential spanking she was about to recieve. It was bad enough that Chrysalis was pretending to be Celestia of all ponies, but this role-playing might already be going to far. But she knew Chrysalis knew that her libido was enjoying this, so if she wanted out she'd have to play along. "Uh... pwease, Pwincess Cewestia, I'ww be a good fiwwy. I no need spankies."

The corners of Chrysalis' mouth turned upward and she placed her hoof gently against Twilight's rear end, rubbing slowly. Twilight moaned into her pacifier, feeling her marehood heat up at the action.

"Really now?" Chrysalis asked her. "Well, maybe if you tell me what a naughty filly you were, I'll consider it." She patted Twilight's bottom teasingly.

Twilight's ears flopped down and her cheeks burned. This was already humiliating enough, but she'd do about anything to stop the spanking that would inevitably turn her on more. "U-uh. I'm a vewy naughty fiwwy, Pwincess. I sowwy I was a whole ten minutes wate to detention." Just saying the words only made her hornier. She thrusted slightly, trying to push her marehood into the padding that had been slipped away from her and hoped Chrysalis hadn't picked up on it.

"And?" Chrysalis asked, tantalizing her with further rubbing.

Twilight moaned. "A-and I sowwy I didn't wear my school uniform. Dat was vewy naughty of me."

"Mmhmm." Chrysalis grinned. "You have been very naughty, Twilight. I'm still not entirely convinced you don't need these spankies. Perhaps if you tell me what naughty thing it was that earned you this detenition, I'll reconsider."

Twilight nodded. "I..." She blinked. Chrysalis hadn't told her the reason for her fictitious detention at all. The conniving little-

"Times up." Chrysalis reared a hoof back and slapped Twilight's butt.

WHACK!

Arousal exploded in Twilight as she felt the initial sting. She moaned into her pacifier louder than before and curled the tips of her hooves.

Chrysalis grinned mischievously. "Do be a dear and keep count, will you Twilight?" WHACK!

"T-Two!" Twilight managed to huff out.

"And be sure to thank me for all my hard work. After all, it's no walk in the park to punish a naughty filly like yourself.

Yeah right, you probably love this more than I do. Twilight thought through the fogginess of arousal.

Whack!

"Thwee... Th-thank woo for punishing me."

Whack!

"F-four. Thank woo... huh huh... Cewestia, for p-punishing me!"

Whack!

"Fuh...Five." Twilight panted and moaned into her pacifier. Celestia's spanks were getting even harder now, and it only served to turn her on more. She knew her marehood was already getting fairly wet just from the first five. And to think this was only halfway to halfway.

Whack!

"SIX! Tank woo Cewestia!"

"You've been a naughty filly, haven't you?" Celestia asked.

Twilight bobbed her head up and down, mind clouding from the horniness. All her inhibitions from earlier were gone; she wanted this more than anything right now. "Imma naughty fiwwy. I desewve dis!"

"You're a filthy filly too, aren't you? Because you love this so much." Whack!

"S-s-s-seven," Twilight panted out. "I wuv dis, Cewestia. I desewve dis. I been a bad, b-bad fiwwy."

"Yes you have." Whack!

"OooOooh! Ei-Eigh-Eight!" Twilight rubbed her cheek up against her teacher, nuzzling her belly. "I a diwty, fiwthy, naughty fiwwy! Thank woo for dis!"

Celestia grinned as she looked down at her pupil; she had her right were she wanted her.

Whack! Whack! Whack! Whack! WHACK!

Spanks peppered Twilight's rear end in rapid succession. She lost count immediately in her haze of arousal. Twilight could only bite down harder on her pacifier each time Celestia's hoof made contact with her bare ass. The stinging sensation was powerful, but it was nothing compared to how turned on she was. Her damp sex pressed against Celestia's thigh, needing some way of relief.

"Bad girl, Twilight." Whack! Whack! Whack! "You know better than to try and come on to your teacher. Without permission."

"I sowwy! I a bad giwl!" As much as she didn't want to, Twilight obeyed Celestia's orders and lifted her pelvis up and away from her thigh. Unfortunately, this also meant holding her butt high up into the air, just in time for another round of spanking.

WHACK! WHACK! WHACK! WHACK!

They were the harderst spanks yet, and Twilight loved every second of them. "T-Th... Thank-k woo, Cewelstia. I a bad fiwwy. I wuv my spankies!" Twilight wasn't even aware of what she was saying. It was all just mindless babble fueled by her arousal. Unfortunately for her, Chrysalis did.

"You certainly seem to. Tell me, Twilight, how many was that?"

"Uh..." Twilight had absolutely no idea. "Fifteen?" she guessed.

Princess Celestia tsked disappointedly. "And to think you're at the top of the class. That was twenty, Twilight." Celestia gripped her diapers and pulled them back up, threading Twilight's tail through the holes before making sure they were snuggly back in place. "And for the record, you're here because you made a big stink in your diapers during class and then made a big stink about it to the class, remember?" She booped Twilight's nose.

"Y-yes..." Twilight played along. Now encased her in padding again, she was itching to masturbate. Her arousal would fade before too long, leaving her with an aching bottom. But she couldn't pleasure herself in front of the Princess, that would only earn her another detention and...

Wait... Twilight wanted to smack herself. Are you kidding me? I lost myself in this stupid fantasy!

Even in the remnants of her arousal, Twilight had enough sense to be ashamed. Her face burned, giving her two sets of red cheeks, as she realized just how deep Celes-Chrysalis had made her go.

"Well, I believe you learned your lesson. Now toddle on over to your desk and we can begin detention."

"Y-yes ma'am." Twilight looked to the ground in embarrassment, pushing herself up. Her double-diapered, stinging butt made moving difficult. Her legs were pushed so far apart that she had to do the world's most awkward waddle to get anywhere.

Now mobile, Twilight let an old habit get the best of her and she made her way to the front of the room to take a seat there. As she passed the other, empty desks, she imagined them filled with other students who'd gotten detention. They all pointed and laughed at her, making her feel worse than she already did and making her stomach cramp come back.

Her marehood twitched.

Twilight shook her head, dispelling the fantasy. She can't let this keep happening! Already she'd been reduced to this shameful mess; she couldn't let it go any further... right?

I mean... there's no denying that I loved it when Chrysalis spanked me... but it's wrong! It's wrong... I mean, it's not like there's anypony around who will ever see or know about this. B-but at the same time, it's disrespecting to the real Celestia, no matter how much I want it.

...

I want it... don't I?

So many guilty feelings and guilty pleasures flooded Twilight's mind at once. This was unequivocally wrong, she could agree on that much, but at the same time who was going to know? She'd yet to find any real promising methods of escape so far, which meant she was here indefinitely. Living out her darkest, deepest fantasy. With a being who could turn into anypony she wanted. How... awful...

...I guess, if it weren't for the kidnapping circumstance, I'd be loving this without hesitation.

Twilight sighed into her pacifier as she reached a desk on the front row. This was all very confusing, but maybe Chrysalis had been right earlier. All she needed to do was look at this situation from a different angle and maybe she might actually... like it?

She shook her head and started to sit down, but her thick padding made for a tight squeeze. Grunting, she wedged herself in the seat as best she could, ignoring her cramps which seemed to be getting worse. As she finally took a seat, her bottom sank into the padding, but was luckily so thickly coated with plush that it didn't agitate the stinging pain.

"Now then." Chrysalis walked to the front of the room, making sure her ethereal tail brushed up against Twilight teasingly. "You know I'm quite disappointed in you, Twilight."

"I know..." Twilight squirmed at the pressure in her stomach. Why did it hurt so much all of a sudden?

"But I suppose making such a fuss in class is only a small part of a larger problem." She brought a hoof under Twilight's chin and tilted her head up. "Your potty training. After all these years you're the only filly in the whole class who still isn't potty trained."

Twilight's face couldn't possibly flush anymore. Instead she bit down on her pacifier, not even focusing on Chrysalis' little game right now. Gah, why is my stomach so... oh wait.

She needed to poop. Really badly in fact.

Her arousal hadn't let her see it earlier, but she was in desperate need of release. In fact, she didn't think she'd be able to stop it at this point. But how? She hadn't needed to go at all before coming back to the room and now it felt like a dam about to burst. What had happened to make such a change?

Twilight blinked, realizing it suddenly. The milk! Chrysalis said it was different today. Did... did she put laxatives in it?

She looked up to her captor, face a mix a questions and slight arousal. If Chrysalis noticed, she pretended not to, however.

"It's clearly a problem if you're going to interrupt class by-"

FFLRRRRBT!

Twilight doubled over, clenching her gut as she felt it happen. Her tail lifted up as best it could with the chair in the way and she started pooping her diaper.

It was slow at first, but it quickly took a turn for the worse. Mush poured out of Twilight in copious amounts, hitting the diaper and causing it to push out. Twilight grunted and moaned, her arousal coming back at the action of messing herself. The warm mush spread across her cheeks, desperate for somewhere to go as more kept coming. For a solid minute Twilight continued messing her diaper, panting all the while.

When she finally finished, she looked up at Chrysalis, who was shaking her head disappointedly. "You never learn, do you?"

With her libido in full throttle, Twilight decided to play along. "I sowwy," she mumbled. Her hooves drifted to the crotch of her diaper, desperately trying to rub her marehood through the double padding.

Chrysalis feigned disgust. "And now you're trying to touch yourself in front of me?"

Twilight whined as she rubbed her diaper. Through all the teasing and masturbating of the last few days, she hadn't had any form of satisfying release yet. Unfortunately, she'd have to wait a little longer, as Chrysalis wrapped her in her magic and ripped her from the desk.

"Such shameful acts of perversion usually are brought about by something," Chrysalis mused. "Could it be that I turn you on Twilight?"

Shamefully, Twilight nodded her head. "Yes." She was so turned on.

A wry grin appeared on Celestia's face. She backed up to the teacher's desk and took a seat on it, levitating Twilight with her. "Twilight, did you get detention on purpose just to be alone with me?"

"Y-yes." Twilight struggled to touch herself. She was completely trapped by Celestia at this point; she'd have to agree to anything. And. She. Loved it.

Celestia leaned in, their noses almost touching. "Do you want to be the teacher's pet?"

Twilight's eyes widened. "...Yes."

In an instant, the pacifier was ripped from her mouth. The magic holding her cut out a second later, and Celestia pulled her into a tight hug and kissed her. Hard.

Twilight was taken aback by the sudden ferocity of the lips against hers, but she was by no means upset. She moaned, leaning deeper into the kiss.

This is... amazing! The feeling of fur on fur as they nuzzled their faces together, their tongues lightly flicking against one another, and the all so satisfying realization that she was (practically) kissing Princess Celestia.

She felt sad when they finally broke apart, but that sadness only morphed into confusion. Celestia suddenly stood up from the next and grabbed Twilight in her magic. Before Twilight could even ask what was going on, Celestia spun her around and laid her across the desk, bottom to the air and legs dangling over the side.

"Wha-" Twilight was cut off by two white hooves appearing next to her head. She craned her neck and looked up, seeing that Celestia was standing over her. About to mount her.

Chills of excitement and arousal raised down Twilight's spine. She lifted her tail up, exposing her mushy rear. Her marehood shook with pure ecstasy for what was inevitably about to happen.

Celestia smiled. "Good girl."

With those words, she thrusted her crotch against the diaper. Twilight's eyes widened and she gasped. The warm mush in her diaper was pushed and spread around immediately, giving Twilight a pleasure that she'd never been able to reach on her own. Celestia pulled back and thrusted again and again, each time pushing the mess in Twilight's diaper around further.

Her loins were on fire and she started panting as the thrusting became more rapid. She was loving this.

"Good girl, Twilight!" Celestia called out, breathing heavily. "Very good girl!"

She stopped suddenly and flipped Twilight around, this time pushing her pelvis into the crotch of Twilight's diaper. As the padding pushed against her marehood, her saggy rear being pushed back into her by the desk, Twilight buried her face deep in the fluff of Celestia's chest and moaned loudly.

"Imma poopy filly. Imma naughty filly," she murmured, delighting in her own decadence.

"Yes you are," Celestia said as she kept pushing against the diaper. "But you're my naughty filly." She leaned in, seductively whispering the next part right into Twilight's ear. "You're the teacher's pet now."

It was then that Twilight climaxed. The much needed, long awaited orgasm that she'd been denied these passed few days took her body by storm, sending wave after wave of satisfying pleasure. "Oh Celestia!" Her eyes went half-lidded and all the tension in her body dissipated as she relaxed into the desk.

"OooOOOoooOOH!" Celestia shook behind her, eventually relaxing and draping her body over Twilight, wrapping her hooves around her. For a little while they stayed like that, both recovering. "That tasted amazing!"

Tasted? The haze of her horniness and her orgasm faded, allowing Twilight to understand what those words meant. Oh no... did I? ...did she?

Celest-Chrysalis lifted her off the desk and held her in her hooves as she took a seat on the ground. "That was wonderful, Twilight. Thank you."

"I...I...I-I-I..." Twilight couldn't find her voice. She could feel the dampness of the padding from her... episode and the squish of her poop in the rear. Chrysalis hadn't dropped her disguise yet either, only piling on the shame.

They sat there for a moment, Chrysalis holding her in a thankful snuggle and Twilight remaining motionless. She was too ashamed to do anything else. She'd let her lust get the better of her and now she'd disrespected Princess Celestia of all ponies by... by letting a duplicate hump her. How could she ever look the Princess in the eye again? Assuming she'd ever be able to look the real Celestia in the eye.

Twilight sniffled, tears welling up in her eyes. What was wrong with her? How could she let this happen? How could she have lost herself in the enjoyment of it all?

"Twilight?" Chrysalis' voice was concerned now as she likely tasted a noticeable shift in Twilight's emotions.

Twilight sniffled again. "W-what did I do?"

Chrysalis blinked and pulled Twilight's head into her white chest. "Oh, sweetie..."

Tears started running down Twilight's face. "I... I can't believe... I loved it so much and now... What's wrong with me?"

"There there." Chrysalis gently patted her head. "It wasn't your fault, it... it was all me. I made you do all of this."

Twilight shook her head venomously. "No, you didn't make me do anything. I wanted this and... and I can't believe myself." She wiped on of her stockings across her tear-filled eyes. "I'm such a perverted idiot."

Chrysalis patted her back and held her close. She blinked, realizing that staying in the is form wasn't helping the situation and quickly shifted back to her original form. "Twilight... I'm so sorry." She held the crying mare's face close to her chest and cooed soothingly. "This was all my fault, sweetie. I shouldn't have pushed you to do this before I knew you were okay with it. I just wanted to make your fantasies come true, honest."

Twilight sniffled. She wanted to believe her words, but...

Chrysalis sighed. "You've been so conflicted this whole time, and here I am just making things worse. I'm sorry."

Twilight shook her head, and started to try and push away. "No you aren't!"

Chrysalis blinked. "T-Twily?"

She kept struggling, her sadness morphing into anger. She was sick of this. Sick of her desires constantly flipping her back and forth, sick of being a prisoner, sick of all of it. Right now, she felt rage. It would eventually settle into a bitter self-loathing, but for now it lashed out at the one being who could be a scapegoat. "All you've ever wanted was for me to just spout out as much love as possible! Even now! You're only apologizing so I'll stop feeling bad and go back to being a food source for you!" Twilight finally pushed away, landing her squishy rump on the ground, but she didn't let that dissuade her rage. "You don't care about me at all!"

"That's not..." Chrysalis struggled to find the words, her brow creasing in worry. "No, Twilight, I... I truly do care for you. I..."

"I don't want to hear it!" Twilight pressed her hooves to her head, clenching her jaw. "You've been manipulating me this whole time! Making me complacent! Making me care about you! I..." She grunted in frustration and turned away, crossing her hooves. "Just get out."

"Twilight..." Chrysalis touched her shoulder.

"GET OUT!" Twilight shrugged off her hoof.

Chrysalis' jaw slid agape at the outburst. She could tell she'd really upset Twilight this time. Her words weren't enough... she'd just have to leave. "Alright."

She lifted Twilight up in her magic, the unicorn offering protest until she saw that her destination was the crib. Chrysalis laid her down in the crib. "I... I hope we can talk about this later, if you want. I-"

"Just go," Twilight mumbled bitterly, not even deigning to look at her.

"...Okay." On an impulse, Chrysalis leaned over the crib's railing and kissed Twilight on the cheek. Then she left, shutting the door behind her.
