How It Begins

"P-Princess Luna, a-are you absolutely sure she'll like this?"

"Believe me, Celestia will love it." chuckled Princess Luna, "We Alicorns are very sexual creatures and not constant sexual stimulation. It seems my sister hasn't had a good Stallion or Mare in her sheets for at least a good 900 years." A smirk came across the mare on the moon, "And believe me, a little power play will be good for her."

-The Following Night

It was a long day. At least, it felt long. How odd, you'd think after how long Celestia lived to be, the days would feel short by comparison. But the Alicorn Princess dragged her feet down the halls of her castle as she desperately searched for her room, eyes lazily glazing on the doors. The crown she wore was always heavy with responsibility and it grew heavier and heavier with every year.

But the day was over. And Celestia made it to her room. She slammed the door behind her and the Alicorn began to make her way to the comfortable mound of mattress and pillows. Celestia already felt her eyes growing heavy as she got ready to rest her weary head.

Sadly, it wouldn't be as smoothly as she thought. Celestia felt the cold clamping of chains snagging her by her wrists. She was about to scream in astonishment before a rubber ball gag forced itself into her mouth, gagging the Princess as the chains started to wrap around her. Her arms were tied behind her back and her wings down to her back, the Princess falling on her face onto the thankfully soft bed. Celestia tried to recover from this and use her magic, but a clamping on her long horn told her that wasn't gonna happen. A Magic Inhibitor. Even her Magical Powers were useless when this thing was forced onto her horn.

She couldn't believe it! Her, Celestia, was successfully taken down by some unknown assailant. Celestia felt a chill run up her spine as she did her best to maneuver herself on the bed, eyes widening as she saw just who it was who subdued her.

"Good Evening, Princess Celestia." smiled Celestia's faithful student, Twilight Sparkle. Twilight wore an all purple latex suit, thigh-high black boots, her hands were the only thing uncovered by the material and damn did it show off Twilight's curvy body and shone in the moonlit night.

Celestia yelled a garbled command at Twilight, which she couldn't understand because of the gag. Whatever she was saying, Twilight could see she was not pleased. Twilight only snickered at this as she said, "I'm sorry, Celestia, but I...I can't seem to understand what you're saying." Celestia glared at her usually faithful student, who managed to pull herself together. "Anyway, Celestia, I'm not planning some kind of coup. And you're not getting kidnapped." Twilight, using her own magic, levitated a paddle into her hands as she taped it in her hands.

Celestia looked horrified at the wooden implement, screaming into her gag at Twilight. "Oh, what's this? Well, this is a paddle, and, well, you've used one on my flank for years, so we're gonna try it on yours." Celestia continued to howl and scream into her gag, thrashing about on the bed. She found it impossible to move even an inch with the chains and restraints.

Twilight's horn gave off a glow as she levitated her mentor, picking her up for a second before carefully putting her down at the perfect angle, Celestia's bottom up into the air and stripped of her nightgown. Twilight tapped the paddle onto Celestia's large, round ass as the bound princess fought and struggled harder than she ever had before, screaming into her gag as loud as she could to get a guard and restrain Twilight.

But no guard came and all Celestia got was a nice, hard,

WHACK!

Celestia squealed out from the first whack that had struck her bottom, but she'd find that it would only be the beginning of many. The paddle's swats came at a steady rhythm, hitting Celestia's cheeks in a sharp pattern. Left, right, left, right, the paddle swatted and caused Celestia's large ass to bounce and wobble, her flesh changing from white to pink.

Despite Celestia's groans and protest, Twilight's paddling did not stop as the paddle continued to swat across her bottom cheeks until they were a harsher shade of pink. Celestia felt tears starting to form in the corner of her eyes, but that was when Twilight had stopped. Twilight bent down onto the bed and both of her hands roughly groped her mentor's sore ass, getting another squeal.

"You know, Celestia, your ass feels like such a big, warm marshmallow." Twilight said lustfully, squeezing her large behind more despite Celestia's protests, "And I love just how warm it feels now, like a roasted marshmallow." Celestia couldn't fight the blush that was spreading over her face as Twilight gave so much attention to her ass. She gave a yelp through her gag as she felt Twilight's hand go down to her outer thighs, slowly rubbing and stroking to inner thighs.

"Goodness, Celestia, you're trembling." Twilight leaned forward as she whispered into Celestia's ear, sending more shivers up the Princess's spine as Twilight's fingers delicately danced over her lower lips. "Stop trying to fight it, Celestia. If you let it happen, you'll enjoy it."

Celestia bit down on her gag and growled at Twilight, clearly not agreeing with that. Twilight tutted, "Bad, little princess." She lifted her hand up in the air and smacked Celestia's flank, a scream escaping the Princess. "Do I need to paddle you some more?" Celestia's response was to shake her head, her sore ass not wanting to taste more of the paddle.

"Good girl." smiled Twilight, her horn emanating a glow as they forced Celestia to spread her legs further and give her better access to Celestia's pussy. Twilight's hand snaked back down to her pussy as her fingers started to rub her outer lips, some low moans starting to escape through the Sun Princess's gagged lips. "Oh, see?" Twilight leaned forward, her hand continuing to pet Celestia's pussy as she lightly kissed her neck, more moans slipping through the captured Princess. "I knew you'd enjoy this if you allowed yourself too."

Celestia felt her body melt like hot butter as Twilight's fingers caressed and rubbed her sex, her juices starting to leak and trickle down her thighs and onto the sheets. Twilight's hand started to rub faster as her free hand began to slowly rub up and down the shaft of her long horn. Louder moans of surprise were released as Celestia started to buck and jerk, hoping to speed up the slow pace Twilight was going.

"Ah ah ah, Princess." Twilight levitated the paddle, giving a hard whack onto Celestia's right cheek as she shrieked, "We're going to take our time and go as slow as we possibly can. And you're going to enjoy. Every. Second." Twilight told her, giving another swat with her paddle as Celestia gave another cry. "Now are we clear?" Celestia gave a submissive nod as Twilight chuckled, "Very good Princess."

Celestia kept herself as still as she could feel Twilight's finger slip into her soaking wet fingers, slowly in a steady rhythm. She pumped in and out as her opposite her grabbed the shaft of her horn, slowly sliding upward until she finally reached the tip. Drool escaped Celestia's lips as her body twitched and her toes curled. It felt so good, and she wanted more.

Twilight began to use a second finger, but pumping into Celestia's sex still going slow. Her thumb began to gently rub her clit, slowly building her pressure up as Celestia's moans grew more wild and hungry. Meanwhile, Twilight's other hand continued to slowly work her horn's shaft before resting up on the tip, gently rubbing them across the tip, Celestia crying louder as she felt herself getting hotter.

Celestia felt herself on the tip of the ledge, ready to break down in orgasmic pleasure, but that was just when Twilight stopped, leaving Celestia panting like a dog. Celestia weakly looked back, whimpering and trying to beg for Twilight to finish, but Twilight just smirked at the horny Princess.

"Oh no, Celestia. A royal slut like you doesn't get the cum for free." Twilight reached down to Celestia's gag and took the slob-covered ball out of her mouth. "You gotta beg for it. Say, 'Please make me cum, Mistress'." Twilight ordered.

Celestia took in a gulp, swallowing her spit and her pride as she choked out, "P...P-please make me cum, Mistress."

Twilight smirked, levitating her paddle and giving another hard swat onto her right cheek, getting a loud shriek, "Come on, you can do better than that."

"Please make me cum, Mistress!" Celestia repeated.

Twilight nodded, using her powers to now levitate the Sun Mare and forcing her to lie on her back, keeping her legs spread and wet pussy exposed. Twilight's horn gave another bright flash before her rubber suit started to morph. It shrunk down into a corset, exposing her pussy before another flash transformed her pussy, shaping it into a very erect cock, eight inches in length.

"T-Twilight!" gasped Celestia, "W-where did you lea-" Celestia was interrupted by Twilight using her powers to twist Celestia's nipple, giving a shrill shriek.

"Ah ah ah." tutted Twilight, hovering on top of the Sun Mare before lowering herself down, her cock now in Celestia's face, "You will address me as Mistress. And if you want cum, then you better show me how badly you want it."

Celestia bit her lip as she looked at the cock in front of her. She felt conflicted. Part of her didn't want to do this, that she still couldn't believe she was being forced to submit to her student! But at the same time, she wanted this-badly-and she wanted Twilight to rut her with her newly formed dick. Letting her lust rule her, she slowly started to lick the tip of the dick, getting some low moans from Twilight's lips.

Once Celestia was done with the tip and felt her saliva building up, she put her lips around the tip. Her light moans felt so good to Twilight as she started to thrust her cock into her mouth. Celestia's skilled tongue wrapped around Twilight's cock, bobbing her head best she could in the position as she blew her new Mistress, taking her cock deeper and deeper.

"Oh fuck, Celestia. You're so good at this." moaned Twilight, using her magic to hover in the air to give herself leverage. She started to lower her cock deeper into Celestia's mouth and down her throat, forcing Celestia to deep throat Twilight's cock. Celestia's managed to keep her gagging down as Twilight fucked her throat. Twilight slowly started to take it out of Celestia's mouth, the Princess panting heavily, a trail of saliva and pre-cum connecting the two.

"Now then, Princess." smirked Twilight, "Are you ready for a proper fucking?"

"Y-yes, Mistress." panted Celestia, "P-please fuck me like the royal slut I am."

Twilight levitated herself until she was before Celestia's soaked sex, her spit-coated cock just about the entrance. "I know it's been quite a few year, Celestia, so hopefully you'll be able to take it." Celestia looked at her Mistress lustfully as Twilight grabbed her legs, making sure they would stay open as she began to force her cock into her pussy.

Celestia roared and moaned in ecstasy as her student started to pump her cock in and out of her. "Oh fuck yes!" cried Celestia as Twilight rammed her pussy. Twilight was moaning herself, lustfully fucking Celestia. Her pussy was tight, but the spit-made lube and her own juices made it easier for Twilight to ram her large cock in and out. It was hot, but it felt good as she kept going.

"Oh God, Celestia! You're pussy feels so good! You should've been rutted a long time ago!" Twilight cried out in pleasure, one hand raising and slapping Celestia on her ass, "Scream my name, you royal slut!"

"T-Twilight!" cried out Celestia, "I'm so close, Twilight! Please let me cum!" pleaded the princess, feeling her pussy tighten, being closer and closer to her orgasm.

"C-cum with me, Celestia!" Twilight shouted as both mentor and student brought each other to an orgasm. Twilight came inside of Celestia's pussy as it grew tighter, practically milking her magical cock as the Princess herself broke down into an orgasm herself. As both girls relished in the bliss of their release, Twilight began to lie down next to her mentor. Both were panting and tingling with pleasure. Despite her fatigue, Twilight grabbed Celestia by her hair and forced her into a passionate kiss, their lips smashing onto each other as Twilight's tongue dominated her mouth. Both were moaning in aftershocks of pleasure before the kiss broke, the two mages looking each other in the eye.

"So, Celestia." Twilight said, beginning to catch her breath, "How do you feel?"

Celestia gave Twilight a smirk, "Better then I had in centuries."

Punishing the Princess

It was the following evening after Celestia and Twilight's, for a lack of better words, fucking. Celestia looked over her desk as she put her pen down. It was hard for the princess believe that she actually got through her day and finished all paperwork that came with her title of princess. Even when Luna returned from the moon and took a share of the work, it's been many years since Celestia could say she accomplished such a feat. It was like a heavy amount of baggage just came off of her shoulders.

It was so good. And she wanted more.

The door slowly creaked open as Celestia turned her head excitedly. She couldn't hide the smirk on her face as Twilight walked into the room. She walked in with her everyday street clothes, a bag was hanging over her shoulder as she also wore a smirk of her own across her face. Both of them knew that this was going to be another fun night.

"On your feet, Princess." commanded Twilight. Celestia got out of her chair and walked to the center of the room, standing front and center before her Mistress. Twilight noticed the magic inhibitor on Celestia's horn, the device making Celestia powerless. "I see you put the ring on."

"Of course, Twilight." smirked Celestia, "I'm helpless to your command."

Twilight shook her head, her horn glowing as she levitated a riding crop from her bag. She tapped the leathery implement in her hands, "What did you call me, Princess."

Celestia gasped, "O-oh, I'm sorry, Mistress! Please forgive me!"

Twilight smirked back at Celestia, "I think you need to be punished for not addressing me, properly, Princess. Now strip."

"B-but, Mistress-" Celestia yelped as Twilight pointed the crop at her.

"Strip, Princess. Or your punishment will be worse." Twilight warned. Celestia gulped as she grabbed her dress, undoing the straps and beginning to pull her dress down and off of her body. Once her dress was down, she started to take off her tiara and jewelry as she stood there in her yellow underwear and stockings. Her bra held up Celestia's d-cup breasts and her matching thong did nothing to hide her big, round ass.

Twilight pursed her lips, waltzing around Celestia's half-dressed body as she lifted the crop and give her a swift swat onto her bouncy cheeks, causing the voluptuous woman to jump on her toes. "A thong, Princess. That's very naughty." she lectured, "I think your underwear should be confiscated until further notice."

"Y-yes, Mistress." whimpered Celestia as she got to work on undoing her bra. Once it was off, she tugged down her thong down, standing in just her socks. As she moved to remove them, Twilight's swatted her thigh, getting another cry from the Princess.

Twilight eyed Celestia's voluptuous body, "I want the socks on." Twilight pointed her crop to the bed, "Now, bend over. Ass out."

"Yes, Mistress." Celestia moved over to the bed as she bent herself over the bed, sticking her round bottom out as she bit her lip. Her ass was still quite pink after her paddling from the night before, her right cheek especially sore. She felt Twilight's hands grope her ass, grabbing and squeezing her cheeks. "Aaah!" moaned Celestia, "P-please, Mistress! I-I'm still sore from yesterday!"

"Mmm, that's not my problem." Twilight told her firmly as she levitated a leathery belt from her bag. "And I don't believe I asked for your opinion. You just earned yourself more punishment." Twilight looped the belt over in her hands before she got up, "It's time for another spanking, Celestia."

Celestia whimpered as she felt Twilight let go of her ass. She braced herself the best she could, but the sting of the leather belt caused her to cry out in pain from the lash on her left cheek. The second hit her on her right, which got an even louder howl from the Princess as her ass jiggled.

Twilight looked at her jiggling ass lustfully, continuing to lash at her ass in a repetitive pattern. Left, right, left, right. "You have such a perfect ass, Princess. It's such a shame you always have to hide it with your dress." A lash hit across the upper thighs, or sit spots causing a loud shriek to echo through the room, "Or should I say try to hide it? You're such a slutty Princess, Celestia. Wearing tight dresses that show off your curves. You want someone to notice you, don't you? You love it when people stare at your body."

Another lash hit her sit spots, causing Celestia to cry even louder. "I-I'm sorry, Mistress! I do want people to look at my body!" Another lash at the spot got another cry, tears rolling down the Princess's face, "I'm a slut! A slutty Princess!"

Twilight nodded as she set down the belt, "Good little slut." She got a good look at her searing red ass. Twilight leaned down as she started to land kisses on Celestia's burning thighs and ass, "There, there, my slutty Princess." Celestia moaned as she felt Twilight's delicate lips dance across her sore ass, a louder cry of pleasure echoing as she felt Twilight give a slow lick across her outer lips. "Mmm, wet already, Princess? What a little masochist."

Celestia gulped, "Y-yes, Mistress. I-I'm a slutty masochist."

"That must mean your punishment wasn't very effective." Twilight levitated a long, purple dildo from her bag. She hovered it in front of Celestia's face so she could see it. "You must be punished more, don't you?"

"Y-yes, Mistress. I-I must be punished." gulped Celestia as Twilight levitated the dildo back to her. Celestia squealed as she felt the dildo rub against her soaking wet pussy. Twilight pushed the dildo into her pussy, causing Celestia to moan in ecstasy, her legs shaking as she felt Twilight thrust the dildo in and out of her pussy at a fast pace.

Celestia moaned at the top of her lungs, but just as it started to feel close, Twilight had stopped, smacking Celestia on her right cheek as she gasped in pain. "Keep that right there." Twilight commanded as Celestia whimpered. Twilight rolled her eyes, giving Celestia another smack as she scolded, "Do you want a real reason to whimper, Princess?"

"N-no."

Twilight landed five more smacks at Celestia's bouncy ass, "No, what?"

"No, Mistress!"

"Good." Twilight could hear Celestia's trembling breath as Twilight began casting her futa spell, her long cock erecting from where her pussy was. She tapped the dick on her sore, red ass. "Hmm, what a nice, hot ass I'm gonna tap." A gasp came from Celestia as Twilight leaned forward, mouth to Celestia's ear. "It's been well over 900 years, Princess. I wonder how tight you'll be." She began to nibble on Celestia's ear, "If you had behaved yourself like a good, slutty Princess, I would lube this bad boy up first. It'll be like a hot shower: it'll hurt at first, but you'll start to love it!" She gave a harder bite onto her ear as Celestia whimpered, "And if you don't, I'll make you like it."

Celestia bit her lip as her body trembled in anticipation, her body clenching up. Twilight expected this and as she slowly got off from on top of Celestia, she moved down to the dildo and flipping a switch. It slowly began to vibrate inside of Celestia's pussy, getting a loud moan in her surprise, the princess beginning to purr from the stimulation.

With her body less tense, Twilght took her cock and shoved it into her ass without hesitation. She heard Celestia cry out as the pain that was shooting through her ass was worse than she imagined. Twilight pounded her like a horse in heat, grabbing onto Celestia's sore ass cheeks as she rammed the Princess. Celestia was screaming at the top of her lungs as she was roughly fucked, her tight ass feeling as thought it was being torn apart. Tears streamed down Celestia's face against as the wave of pain was being mixed with a new wave. Of pleasure. Her pussy was flowing like a river, having fallen out by now due to how rough Twilight rutted her ass and from how much of her juices leaked and soaked the bed sheets.

"Please, Mistress! Fuck me! Fuck me harder!" cried Celestia. Twilight felt a bestial growl escape her throat as she complied with Celestia's screaming, finding it in her to go harder and faster then she had before. She pumped her cock in and out of Celestia, going deeper and deeper until her newly formed balls slapped against Celestia's sore ass. It hurt, but Celestia only gave moan-filled screams.

"I-I'm cumming!" cried Celestia in a castle-shaking scream as Celestia came. It wasn't much longer until Twilight gave a final shove, shooting her load into Celestia's ass, which brought Celestia into another squirting orgasm.

Twilight panted as she slowly began to pull out of Celestia's ass, the Princess of the Sun falling onto her bed, face first, as her body twitched. A wide grin had spread across her face as she panted.

"What a...bad girl you are." Twilight managed to say, using her magic to levitate Celestia further up on the bed, resting her head on the pillows as cum dripped out of her ass, "You didn't...ask me if you could cum."

Celestia gave out a few giggles as she said, "O-oh my...I must be...punished next time then." She reached down at one of the covers and pulled it up, "But for now, may I please cuddle with you, Mistress?"

Twilight smiled, "You never have to ask for that, Princess." she said, starting to crawl up the bed to lie down next to her sub.

-The Following Morning

"I-I am so sorry, Celestia..." mumbled Twilight as she walked in with another stack of papers in her hands, "I-I should not have been so rough with your bottom last night."

"Bottom? You sure weren't shy on using more colorful language when you pounded my 'bottom'." Celestia couldn't help but giggle at Twilight's blushing. How someone as sweet and innocent as Twilight transform into someone so different was mindbogglingly. She took the papers from Twilight as she prepared her pen, "But honestly, Twilight. Don't apologize. The pain is well worth it."

Celestia was dressed in her usual royal dress, said dress being pulled up to reviel her red ass being nursed with an icepack. The Princess lying down on her belly with a wooden board on her bed so she'd be able to work while resting her ass. It was much too sore to sit and walking and standing required the aid of magic.

"I guess now is a good time to follow through on that underwear prohibition." Celestia said casually, "Putting on my panties will be very difficult with my ass so sore."

Twilight snorted as she tried to hold back her giggling, "I better not catch you with any underwear, Princess. Or it's the paddle."

Celestia gave a noticeable cringe as Twilight covered her mouth. "Twilight, if I might make a suggestion...perhaps you could go easy on my poor ass?" Masochist or not, Celestia liked being able to sit down.

Author's Note

A quick reminder that like it says in the description, the plot is mostly an excuse for clop, so you should not expect much from this fic other than a series of Twilight doming Celestia.

With that said, I will try to veer away from spanking and might try to take suggestions as to what the next scene may or may not be. No promises on either, since spanking is a major kink of mine, but we'll see.

Good Princess

WARNING: Contains small amounts Petplay

Fire.

That's all Celestia felt: pure fire racing through her body. The Princess of Equestria lied on her large bed, turning and twisting for what felt like hours in this uncomfortable heat. The Alicorn found it impossible not to pant like a dog. How fitting as she was a literal bitch in heat.

It seemed like such a good idea at the time. Celestia always a fascination with petplay. It was one thing to give up her power to someone she trusted, but to be treated like a sexual animal, it seemed to exotic and exciting. She was so excited when Twilight told her she'd indulge her in her fantasy, but now she was starting to regret this decision as she lied on the bed, feeling her pussy grow wetter and hotter but powerless to do anything to put out this fire.

-Earlier That Night

"Alright, Celestia, are you ready?" smirked Twilight, staring at her mentor and sub. Celestia was on her hands and knees on her large, soft bed. She stared up at Twilight, a pair of dog ears were placed over her pony ones. From her elbows down to her fingers, they were coated in a magical-rubber gloves that ended in finger less mittens. Her gloves made her 'paws' useless for anything but fetish gear. She wore the same type of material as knee-high, heeled boots. The last piece of Celestia's attire was a special gold collar, it's tag being in the shape of Twilight's cutie mark.

"Ready, Mistress." Celestia said, giving an enticing pant as she shook her ass and wagged her tail to show her excitement like a dog.

Twilight snickered a bit as she took out a plastic container. "Okay, Celestia. I firmly believe in positive reinforcement. So, for your training, I'm going to give you something to incite you to behave tonight." She opened the container, Celestia's eyes widening as she saw Twilight levitate a slice of chocolate cake. The rich smell assaulting her nose as Celestia felt her mouth water. "Here's a slice of cake, Celestia. If you behave yourself, you'll get more cake."

Twilight had the cake hover in Celestia's face. Celestia tried taking a bite, but Twilight immediately pulled it away from her, "Ah ah ah, you have to beg for it. Beg like a dog." Celestia pouted at Twilight. She knew her weakness and was exploiting it! Celestia stood up straight on her knees as she gave some sad, pathetic whimpers. She lowered her ears and had her lower lip quiver to give the saddest look she could give. "Good girl." smiled Twilight, levitating the cake over so Celestia could eat it out the air, "Now eat."

Celestia bit into the cake, moaning softly at it's fresh, soft chocolate. It tasted like it just came out the oven and was still quite warm. The cake wasn't just good-it tasted better then any cake Celestia had before. Every bite sent waves of pleasure through her body as the warm chocolate tickled her tongue. As she kept eating the slice,she felt a certain warmth resonating through her body.

By the time she had finished, Celestia was panting. She felt her body shivering as she bit her lip. Something was coming over her, a sudden neediness and heat that came from her very core.

"I think by now you've realized something about that cake wasn't right." chuckled Twilight as she saw the confused arousal come over Celestia. She reached down and gently tweaked her erect nipples as a loud moan came from the Sun Mare, "That cake was baked with a fast acting lust spell." Her hand started to rub down Celestia's twitching curves and squeezing her thighs, "You must be feeling so horny right now."

"T-Twilight, I-I...oh Gods, my body feels so hot." moaned Celestia, trying to form a concrete thought in her lustful haze. Twilight took her hand out of her nipple and firmly grabbed Celestia by her hair, pulling her forward and crashing her lips onto Celestia's. Twilight forced her dominance onto Celestia, who weakly submitted to her Mistress as their lips were entangled with each other's. The chocolaty aftertaste of Celestia's mouth put Twilight in ecstasy as she found herself getting traces of Celestia's lust potion. Not enough to make her a moaning mess like her sub was, but it did shoot waves of pleasure of her body.

Twilight lightly bit down on Celestia's lower lip, the Sun Mare whimpered slightly as she gave Twilight entrance to her mouth. Twilight's tongue pushed inside, claiming her mouth for her own. Her hand started to rub Celestia's inner thighs, a high-pitched moan escaping her mouth as Twilight rewarded her for her obedience. Her hand rubbed against her inner thigh as her hand grew closer and closer to Celestia's sopping wet pussy. Celestia could feel her hand just inches away from touching her

But then, Twilight stopped, pulling away from the kiss and Celestia's pussy.

"Oh my, I think I forgot something." Twilight said, pushing Celestia onto her back as she started to get up. Celestia looked astonished, completely caught off guard from Twilight's sudden halt. "I think I left something in the kitchen when I was overseeing your cake. I'd better go get it."

"T-Twilight, c-can't it w-" Celestia was interrupted by a gag being levitated and forced in her mouth.

"Bad Princess, no talking." Twilight said sternly as Celestia was taken back. Celestia tried to whimper as her rubber paws directed to her hot, wet pussy. "Oh, I'm sorry, Princess, but we can't keep playing unless I run an errand." Twilight slowly headed to the door, a wide smirk on her face.

Celestia whined and whined as she tried to tell Twilight to come back, that she needed her touch. Celestia tried to undo the gag so she could scream, but alas, her mittens had no way for her to take off the ball gag and her magic inhibitor kept her cut off from her magic. As Celestia saw Twilight begin to open the door, the horny Princess felt herself getting even hotter.

The door opened, Twilight had started to leave. With her back turned, Celestia tried to rub her paw against her twitching snatch. She could hardly keep down her moaning as she rubbed the cold rubber against her hot pussy. Maybe if she kept this up, she'd finally hit that climax. It was so good she didn't notice the ropes that was hovering before her wrist was in the process of being tied. She tried to swat the rope away, but it was persistent. The rope had tied her wrists behind her back and forced her onto her stomach. Another rope started to tie her legs together as Celestia looked up and saw Twilight smirking at the door.

"I knew you couldn't resist." chuckled Twilight, "Naughty puppy, no touching yourself without permission. Now I gotta tie up my poor puppy." Celestia was howling and screaming as she tried to plead with Twilight. The smaller Alicorn could make out Celestia trying to say 'sorry' and 'please', but she'd have none of it. "Oh no, Princess. I have to teach you to behave." She levitated a black cloth and tied it over Celestia's eyes, "Now you stay right there until I get back, Princess." She giggled a bit before she began to close the door. The last thing Celestia would hear of Twilight was the sound of the door closing.

-Now

It might have been a mere 10 minutes, but Celestia swore it felt like hours. She could feel the passing of every second as she squirmed and twisted on the bed. She desperately tried to rub her bound legs together, hopping to get herself off. But it was pointless, all it did was add to her frustration.

The solitude was making Celestia go mad-insane with lust. She couldn't see, there was nothing to hear, her own voice was muffled and all she could feel was the soft cold bed sheets on her naked frame and the taste of the rubber ball gag. She couldn't help but shiver, she never knew her room was so cold until it was all she could focus on, but with her body feeling so hot, it shot waves of pleasure through her body. The mere touch of the sheets were enough to arouse Celestia, drool and sexual juices leaking onto those sheets.

But she was still helpless to cum.

Celestia desperately tried to cry out for Twilight, but it was all muffled cries of nonsense. By now, Celestia knew her cries were pointless and that her tossing and turning was just making her tired and hornier, so she lied there on the bed, her body shivering and twitching.

By the time the 15th minute mark hit-or 15 hours, Celestia couldn't tell-the Princess heard the door opening. Celestia yelped, her ears incredibly alert to the small sound. Was it Twilight? Luna? A random guard?! She couldn't tell who and that alone made her incredibly excited. What would they do to her naked, helpless body? She didn't care what they'd do, she just wanted them do do it-now.

When she heard the door click, it was followed by the slow footsteps dancing across the floor. She felt a painfully cold piece of plastic touch her snatch and slowly slide up, rubbing against her clit as Celestia gave out a high-pitched moan that echoed through the room.

"My word, Princess, your body is soaking wet." It was Twilight's voice. Her sweet, angelic voice that was being whispered into her ear. "I've hardly even touched you and you're practically on the edge." Twilight nibbled on her ear as Twilight shivered in delight, her legs bucking as she thrusted her hips wildly. Twilight smirked as she lightly breathed on Celestia's neck, "I wonder if you could cum from just this. Me lightly nibbling on your ear and whispering into your ear."

Celestia gave a loud groan in disagreement, bucking and hurriedly trying to force her bigger body closer to Twilight. She could very well hit her climax, but not as soon as she'd like. No, she wanted to cum-now! Her desperation got a giggle from Twilight.

"Aw, does my cute little puppy want a big, juicy bone?" Twilight asked, levitating her dildo and began to slowly rub it onto Celestia's outer lips. Celestia howled as she hurriedly nodded her head. "Hm...I don't know, it doesn't look like you want a bone." Twilight took the dildo away as Celestia screamed and cried for it. "Hmm...beg." Twilight ordered. Celestia tried to plead through her gag, but Twilight silenced her by rubbing the tip of her horn, reducing Celestia to a mess of sloppy moans through her dripping-wet gag.

"No, Princess. Beg like the sad little puppy you are." Twilight ordered as she got off of Celestia. Celestia panted as she weakly began to give a loud, pathetic whining noise through her gag.

"Good, good." Twilight giggled, "Now roll over." Celestia groaned, tossing and turning before she eventually managed to roll over, landing on her back as she panted. Her pussy was sopping wet and no on her back, it felt as though the cold air was biting at her wet core. It was driving her insane, but it felt so good at the same time. With her magic, Twilight began to untie Celestia's legs. "Spread." Once the command was made, Celestia spread her legs, revieling more of her wet pussy as she waited anxiously for her lover to douse the fire in her loins.

"What a good girl." Twilight chuckled, holding up her dildo by her telekinetic powers. It was a large toy, 12 full inches. She gently rubbed her slit with the toy as she climbed onto the bed. Celestia gave a loud gasp, moaning and bucking, trying to stop Twilight's teasing and take that whole dildo in if she had to. Twilight pulled the toy away and gave Celestia a slap on her thigh, "No. Bad dog. You will wait for your bone or you won't get it at all." Celestia gave another sad whine, begging for her lover to take her now.

"Are you going to be a good dog?" Twilight asked as Celestia hurriedly nodded her head. "Well, okay. But this is your last chance, Princess. Misbehave and you won't finish." Celestia hurriedly nodded as Twilight began to slowly rub her pussy with the dildo. Slowly, achingly, she teased the Sun Mare. Celestia panted, trembling as she desperately tried to hold the position. "Yield, mutt." Twilight spoke in a harsh tone as she tried to make Celestia refrain from struggling. Celestia whimpered, but managed to fight her lustful desires to hump the cock before her.

"Good girl." Twilight continued her slow teasing as she got down on her knees, lightly kissing Celestia's inner thighs. Celestia's moans grew louder, it wasn't fair! Twilight was torturing her! She was tempting her to disobey, to desperately hump her bone and try to reach her climax, but she had to wait! It was madness, but she held on. Her pussy leaked juices and she was a moaning mess from Twilight kissing and lightly biting her inner thighs, but she obeyed her Mistress, reluctant and desperately.

"Ooh, what a good little Princess. I think you need a treat." Twilight began to crawl onto the bed. Once she was next to Celestia, she whispered into her ear, "Here it comes. Your big, juicy bone."

Twilight began to thrust the foot-long toy into Celestia's wet snatch as she moaned in satisfaction. Twilight had pushed in four of those 12 inches as she fucked Celestia with the toy, rapidly going in and out of Celestia hot, wet pussy. Twilight's hands had gotten to work in the meantime, one hand groping and squeezing Celestia's nipples as the other started to undo her gag. After hearing a symphony of cries and moans of pleasure, she forced her lips onto Celestia. Celestia's lips wrapped around Twilight as the smaller Alicorn forced her tongue into Celestia's mouth, tickling her tongue as Celestia let her ravage her.

Twilight moaned as dominated Celestia's mouth, subconsciously starting to push that dildo deeper into the Sun Mare's pussy, much to her pleasure. Six, eight, ten. With a final thrust, Twilight forced that dildo as far as it could go as Celestia screamed into her mouth, releasing a powerful orgasm into onto the toy and bed.

Twilight aloud Celestia to spurt and spasm, her body twitching as she lied their in ecstasy. She panted, the cold air returning to nip at her sweaty, exhausted body as Twilight slowly pulled the toy cock out of Celestia. Twilight's hand reached over to Celestia's blindfold and pulled it off, her eyes practically rolling back into her head as Twilight undid the rope around her wrists.

"Good Princess." Twilight petted Celestia's face, who tiredly nuzzled her hand.

Celestia's 'Big' Cock

"Are you sure you wanna do this?" asked Twilight as she stood in front of her mentor. She watched as Celestia had began to strip out of her clothes to get ready for another night of run.

Celestia gave a cheeky grin, "Aw, are you nervous cause you know my cock will be bigger then yours?" Celestia had began to pull down her panties, showing off her ass to Twilight who gave her Princess a glare. Celestia hadn't put on her magic inhibitor yet as she wanted to use the Futanari Spell on herself.

"Be careful, Princess. I'll have to punish you for talking to your Mistress like that." scolded Twilight, hands on her hip as she stood in a purple latex corset with matching elbow gloves and knee-high boots. She had already cast the spell on herself, her aroused, eight inch cock standing upright and erect. It was hard to not get a hard-on as she watched someone as beautiful as Celestia do a strip tease in front of her.

"Oh, I'm so sorry, Mistress." Celestia's tone was anything but sorrowful, which Twilight planned to hold against her. Celestia cast the spell on herself as she boldly stood above Twilight with a smirk, "Well, what do you think, Twilight?"

"Is...that as big as it gets?"

Celestia's smirk left her face and curled up onto Twilight's face as the two Princesses compared their cocks. Celestia's couldn't have been more than four inches and it was clearly erect, where as Twilight's was a full five inches bigger and thicker. Celestia felt her face heat up, this was so embarrassing! She was so much older and taller than Twilight. It shouldn't have meant anything to do, and yet, seeing how she measured up to Twilight like this was just so humiliating.

"Aw come on, Princess. Don't be bashful." Twilight couldn't stop herself from snickering as she snaked around Celestia, her hands resting on her hips as she levitated her magic inhibitor. "It's only fitting that the Mistress has a bigger dick." Once the inhibitor was on Celestia's horn, she began to gently stroke her hard-on, getting a moan to escape her lips. Twilight slowly began to stroke her cock, Celestia panting as she eagerly thrusted iinto Twilight's hand.

"O-oh Gods, i-it's so amazing." Celestia couldn't have known that her new cock would be so sensitive. Every stroke felt amazing. Twilight's slow, teasing speed began to pick up the pace, causing a euphoric wail to erupt from Celestia's mouth as she begged, "P-please, m-more."

Twilight giggled, taking a moment to stop as she gently licked her lips clean of the pre-cum that was dripping from Celestia's cock, "Mmm, Princess. You taste so good." she told her, "Your cock is practically coated with your cum." Celestia was panting as Twilight glided her fingers up and down the shaft.

"T-Twilight!" moaned Celestia, her cock twitching and excited.

"Tsk, tsk, tsk." Twilight gave Celestia a slap on her thigh, which got a squeak from the Princess, "That's not how you address me."

"O-oh, I'm sorry, Mistress! Please forgive me!"

Twilight smirked, rubbing her thigh, "Bad, bad Princess." Celestia couldn't help but purr as Twilight rubbed her stinging thigh. "Forgetting your place, making demands. We can't have a disobedient pet. No, you must be punished. Princesses who disobey must be punished for their bad behavior." Celestia gave a yelp as she felt something tight constrict around her cock. It felt like a tight ring that wrapped around the base. "Now, sit down."

"Y-yes, Mistress." Celestia nodded submissively as she moved over to her bed and sat. Twilight started to levitate the 12 inch dildo from her bag. "On your back." Twilight commanded as Celestia lied on her back as instructed. Twilight gave the toy a special glow as it began to float over Celestia's mouth.

"..." Twilight took the crop and swatted it on Celestia's thigh, getting a yelp from the Alicorn. "It won't suck itself, Princess."

"I-I'm sorry, Mistress!" Celestia started kissing the toy's tip, her tongue beginning to lap at the head. The dildo seemed to move in response to Celestia's tongue, moving closer and closer before pushing itself into her mouth. The dildo thrusted in and out of Celestia's mouth as Celestia sucked and bobbed her head in rhythm. Celestia reached up her hand to try and stroke the toy with her hand, but she felt her hand freeze in place.

"Ah ah ah, Princess." smirked Twilight as cuff snapped onto Celestia's wrist and pulled her hand away from the cock. "No hands, mouth only." Instructed Twilight as another glow came around the toy. It started to thrust into her mouth faster, and deeper, going deeper and deeper until seven inches was being forced down Celestia's throat. Managing not to gag, Celestia continued to suck and take the cock with her mouth. Her tongue started to work the cock expertly as it shoved itself in and out of her head, stroking it like it was her own hand. That got the cock to twitch as it thrusted harder.

Celestia felt as though her mind was going numb. It was a toy. It tasted of rubber. And yet, it felt so real. It felt so arousing and naughty for Celestia, to be used like some harlot. She felt her cock grow harder and more aroused, a heat rising in her small futa dick as she eagerly humped the air, wanting to be touched and played with. Celestia's humping didn't stop Twilight from cuffing Celestia's ankle and forced aside. The same happened to her other leg and arm, leaving Celestia spread-eagle over her bed.

"It looks like you're nice and ready." giggled Twilight, removing the dildo from Celestia's mouth as she panted. Drool trialed down her chin and precum leaked from her cock. A moan escaped her lips as Twilight trailed her finger slowly up her dick and taking in a sample of her cum. With a seductive lick of her finger, Twilight smirked, "My my, aren't you excited." Twilight hovered over Celestia before lying next to the larger Alicorn. A hand groped one of her breasts, "You've been so needy, Celestia."

Twilight started to kiss Celestia's chin, getting a pleasurable shiver from the Princess. Twilight kissed and licked away Celestia's drool, taking in the taste of her sub. She pinched at Celestia's nipple as started to tug, getting a louder shriek from the Princess.

"Now you'll be punished for your lust." Twilight told Celestia, levitating the dildo down to Celestia's ass, rubbing it against her hole. With her legs spread apart, she was fully exposed to Twilight's toy. Twilight slowly rubbed the toy against the hole, teasingly pushing the toy's tip in. She gave a few twists, and pulled the toy out. She repeated this as Celestia moaned and whimpered, unable to greedily take the cock in as she took it.

The teasing didn't last long as Twilight started to push in the lubricated cock into Celestia's ass, her whimpering turning into roars of ecstasy. Twilight pumped the cock into Celestia's at a fast rate. She pushed the cock deeper and deeper inside her. She was already taking in ten inches as Celestia was moaning and panting lustfully.

"M-more! M-more, please!" howled Celestia as Twilight kept thrusting the dildo into her. The pressure in her ass was driving her crazy as she grew closer and closer to the edge. It felt like she needed more, just a little more to be pushed over, but she just couldn't. Not yet. Celestia was biting her lip and groaning as the cock was pushed deeper. By now, Twilight was pushing in all 12 inches and sucking on her nipples. It was all so good, but Celestia couldn't cum.

Celestia grew frantic, desperately trying to fight against her binds. She tried to hump Twilight's dildo, but the chains prevented it. Her cries of pleasure turned to frustration, her moaning turning to groaning as her cock couldn't unleash it's load. That's when it occurred to Celestia, the tight ring around her cock grew so much tighter and restricted her further.

"Aw, does my little Princess wanna cum?" smirked Twilight as she cotninued to plow Celestia's ass. Celestia frantically nodded her head. Twilight tutted, slapping both of her breasts as she squealed. "That's not an acceptable answer."

"P-please, Mistress!" pleaded Celestia, desperate to reach her climax, "L-let me cum! L-let your slut cum!"

Twilight giggled at the desperation in Celestia's voice, "Okay, Princess, you can have your precious little orgasm." Twilight smirked evilly as she thrusted the cock harder, getting another cry from the Sun Mare. "Just as soon as you give an oral report on how this big cock feels inside your slutty ass."

"M-Mistress, I-I can't c-concentrate!" cried Celestia as Twilight gave her a disapproving glare. She started to thrusts harder, all 12 inches roughly ramming into her ass as she twitched and weakly squirmed.

"You will concentrate and you will tell me or I will stop and leave you here." Twilight smirked at the paniced look on her Princess's face. She slowly pulled the cock out of her ass, "That's right, Celestia. I'll leave you right here, tied to your bed, orgasm denied from you, and being routinely fucked by my dildo until dawn or someone comes to check on you."

Celestia bit her lip nervously, Twilight sounded so serious! Twilight leaned into her ear, her ass gaping with the cock out. The dildo levitated over and rubbed against Celestia's own dick, getting a weak moan as she felt Twilight's breath on her ear and neck. "Is that what you want, Princess? Do you want to be lying on your bed? Naked, restrained, and with your little cock unable to cum?"

"N-no."

Twilight had her cock rub the tip of Celestia as Celestia gave a louder moan. Precum started to leak a pathetic piddle of cum as Twilight giggled. "You're lying, Princess. Your body is telling me you want that. You want to be left here. Frustrated. Unfinished. Needy." She bit on Celestia's neck as she cried out desperately. She could feel the dildo leave her cock and started to ram her ass again. It was faster and harder than ever before, "You want the guards to come in and take advantage of your vulnerable body. You want your sister to come in and be ashamed of you. You want everyone to know that Princess Celestia is a cum-hungry slut." She started to get off of Celestia. Celestia looked in horror as Twilight stood up off the bed.

"N-no! No, please Mistress!" Celestia cried out in desperation, fighting the cuffs harder than before as she wildly tried to free herself. "Please, Mistress! Don't leave me like this! L-let me cum, I'll do anything!"

Twilight glared at Celestia, crossing her arms, "I'm waiting for your report, Celestia."

Celestia whimpered as the toy hammered her ass. "I-it f-feels s-s-so good, Mistress!"

Twilight tutted, picking her crop up and giving three harsh lashes onto her helpless thighs, causing Celestia to squirm and struggle helplessly as the dildo thrusted even faster. "Bad, Princess! You can do better!" scolded Twilight as the dildo pumped faster and harder.

Celestia felt the hot pain in her ass and on her thighs. It hurt, but it hurt so good. The panting sun mare felt words escape her as she whimpered and struggled again, wanting badly to be allowed to release. It was pure sexual torture and she loved it.

"M-my ass f-f-feels like i-it's on fire! L-like it's being torn apart! Th-the rubber is rubbing against m-my slutty hole and i-i-i-oh GODS, MISTRESS! M-MORE!" howled Celestia, not able to keep it together. She gave another scream as her thighs got three more lashes from the crop.

"That's a fragment sentence, Celestia. Finish it."

"THE RUBBER IS RUBBING AGAINST MY SLUTTY HOLE AND IT'S MAKING ME GO CRAZY! PL-PLEASE MAKE ME CUM!" Celestia cried at the top of her lungs.

Twilight smirked as she leaned down, stealing Celestia's lips in a kiss. While Twilight was hot and passionate, Celestia's was wet and sloppy, desperately trying to take in Twilight's tongue as Twilight started to dominate her mouth. Her tongue forced itself down Celestia's throat as the older Alicorn moaned into her dom's mouth. Twilight had dispelled the ring around Celestia's cock as, finally, Celestia could feel that edged pressure reach it's climax. With a castle-shaking scream, Celestia's cock unloaded a large amount of cock into the air as it fell all over Celestia's lower body and belly.

When Twilight released her grasp on Celestia, Celestia was panting. Her body had finally relaxed and had gone limp-around with her new cock as the older Alicorn found herself out of breath and gasping.

"Love you." giggled Twilight, kissing Celestia a gentle kiss on her cheek as she undid the cuffs on Celestia's ankles and wrists. "Let's try and clean you up first before we go to sleep."

Celestia had long since stopped listening. She was too far gone and basking in the afterglow of their session.

-The Following Morning

"Good morning, sister." smiled Luna as she saw her sister walk into the kitchen. A yawn escaped Celestia's lips as Luna handed her a mug. "Coffee?"

"Preferably with plenty of sugar." giggled the sun mare as she grabbed the mug and started to drink.

"You seem awfully refreshed this morning." Luna noted as, aside from her yawn, Celestia was looking as chipper as ever.

Celestia shrugged nonchalantly, "I guess you could say I slept very well." Celestia resumed gulping down her miracle drink.

Luna nodded understandingly, grabbing the kettle and pouring herself a cup of tea. "Understandable." Luna gave a calm sip. "But sister, the next time you and Twilight have another one of your sessions, might I suggest you get a gag."

Celestia choked on her coffee, spitting it out onto the floor as she coughed and gasped for air.

"How about a sound proof spell?"

"L-LUNA!" whined the Sun Mare, blushing an incredibly bright shade of red as her little sister gave her sex advice.
