A sharp blast of searing flame jolted her awake, bringing the world in a blurry haze of images and scents. Even in the darkness, she could make out the softly rounded curves of the hollow tree. The scent of oak and parchment tickled at her nose, blanketing her with a reassuring sensation of familiarity. She was in the library. She was home.

And yet, thats what frightened Twilight the most; That and the three words that were whispered lazily into her ear as Twilight's hazy conscious turned to focused fear.

"Whats the score?"

She was bent over the side of her bed, her limbs rebelling against her commands, and a cold tingle of a spell danced through her veins. Her mind was a jumble of jagged glyphs and shapes; spells that came together to form nothing and incantations of gibberish. Some sort of magic restraint that kept her mystic abilities at bay. Had she the concentration, Twilight was positive she could have figured out a counter spell; a magical lock pick that could blast her bonds into oblivion and unleash the full potential of her powers. Unfortunately, concentration was the last thing Twilight was allowed to have. Trixie would see to that. She struggled, but found no reprive; each limb limp and lifeless and yet, strangely enough every nerve was alive and sharp. She swallowed a lump in her throat and tried to twist herself around to peer at her surroundings, but the spell kept her solidly bent over- a compromising position she knew was not going to go to waste. She could feel the presence of her marefriend behind her; grinning from ear to ear even in the darkness. A silvery, Cheshire Cat smile that was sinister as it was wide.

Twilight gulped.

"Whats the score?" Asked a voice from behind her. Twilight felt her pulse quicken, her breathing becoming deep and labored as rushed thoughts and excited sensations began to fill her senses. She bit at her lower lip. If she could keep her cool and her calm, there was a chance- a slim chance- but a chance that should could survive an entire hour without Trixie getting the better of her. She could seize the prize at the end of the month of solid servitude from Trixie, and delight in the way it made her marefriend squirm for the week, but first she had to survive. Easier said than done. Still, her academic mind had pin point laser accuracy when studying. She could lose herself into books for hours and all she had to do was reach that spot in her mind- that place where focus trumped over everything else. She could do this.

The first sensation of Trixie sensually squeezing her behind shattered that illusion immediately. She rubbed slowly, gently, squeezing one cheek, then the other, drawing her hooves softly along the deep dark cleft of Twilight's naked bottom. Twilight squirmed, but was determined to keep her cool. Oh, it felt nice, but it wasn't enough to crack her. She could do this, really she could!

"You've been a naughty little girl, Twilight." A voice whispered, and Twilight's ears perked in alarm. No...No, not this... another slow squeeze, tugging at her right cheek to force it into a little bobble, before it came to rest.

"You haven't been turning in your homework, showing up late to class...I'm afraid you really leave me with no other options. I'm sorry sweetie, this is for your own good." The voice whispered, its owner watching in sadistic glee as Twilight's cheeks turned a violent shade of crimson.

"T-Trixie, this is enough. You've had your fun, this is too far." Twilight sputtered, gasping as she felt the sensation of her tail being raised up into the air- the plump purple buns completely bare and vulnerable, exposing her completely. Not just the twin bouncy globes of her sweet round rump, but the damp little mare sex twitching in plain view. No! NO!

Twilight tried to fight it, forcing her thoughts past the growing embarrassment and humiliation to counter Trixie's spell. She could do this. She could beat this! She knew that she could and there was no way Trixie could ever hop- The hooves squeezed again, bouncing her bottom helplessly, and Twilight gave a squeal of surprise, squeezing her eyes shut. When the next squeeze wasn't applied to the curvaceous contours of her rump, she peeked and eye open and gasped. Instead of the darkness of her bed room was the dark green background of a chalk board in a brightly lit room. Her bed was lost- replaced with the firm wood of a teachers desk. She could hear the giggles- the sneers and jeers of pointing students- everyone in the room getting a front row seat for her upturned, backside Nonono!

"You're a very naughty girl, Twilight. Isn't she class?" The voice called out in a sing song voice, burying Twilight under even further humiliation.

"Yes miss Lulamoon!" Came the return cry. No no no. This isn't real! This isn't happening! This is a spell! Fight it!

"And you know what happens to bad little girls who don't do their homework... Right class?" The voice asked again. Twilight was sweating now. No...no please don't say it. She couldn't handle this. She didn't deserve this! She was a good girl! Really she was! She always did her homework! Always arrived early to class! She didn't deserve-

"A spanking!" The class called out, bursting into giggles and forcing Twilight into a squeal.

"No, NO! No, Miss Lulamoon, I'm a good girl, really I am! I- I mean Trixie, Damn it, Miss Trixie, I don't deserve a s-spanking! T-this is all a mistake!" Twilight barked, trying to force the classroom to change back into her room. To turn the tables and make th- The first POP of the ruler caught her by surprise, forcing her ass to bounce and flex in front of the eyes of her peers.

"OH yes, a very naughty little girl indeed! Can you see class? Only naughty little fillies get wet from a punishment!" The voice barked. The classroom filled with laughter and Twilight could feel a cool breath rolling over her exposed sex. No no no! She was a good girl! This wasn't turning her on at all!

Another clap of the ruler- forcing her rear end into a rhythmic wobble and bounce, dancing erotically with each firm slash across her reddening behind.

"And just look at this, Twilight's been eating far to many cookies, no wonder she has such a bounce! "The class erupted into laughter again, and Twilight could feel the sensation of something warm and wet running gently down her inner thigh. The ruler pressed firmly against her bottom and Trixie gave a wicked laugh.

"Fattest plot this side of Canterlot!" She called. The class erupted into laughter, and Twilight turned a darker shade of red. Ok, maybe she'd been studying a bit too much but she didn't think it had gotten that out of hand. She struggled against her bindings again, whimpering at the sound of the class giggling behind her.

"Lines, Twilight. Lines, little filly. "Came Trixie's voice, while a little white stick of chalk danced in circles in front of Twilight's nose.

Smack! Whack! Crack! The ruler spit a fierce flame across both of her butt cheeks. Right, left, right, left, like some weird, exotic march. She knew very well each blow forced her bottom cheeks to wobble and bounce, spreading apart and wobbling together, and each time they did so, Trixie was greeted with the sight of her private little purple pucker, and the damp mare sex just below. Left, right, left, right, it made Twilight gasp and whimper, rolling her hips as best she could as the rain of spanks continued down. Soon both her cheeks were glowing red, and the tingling sensation of pain was quickly being replaced by a lustful need for more. Oh, it was a heat that almost instantly transferred from her bottom to between her legs, leaving Twilight gasping helplessly over Trixie's desk.

"I'm a naughty girl that deserves a spanking." one hundred times on the board, chop chop!" Miss Lulamoon announced, giving Twilight's rump a few light swats with the ruler. Twilight gently took hold of the chalk with her magic- telekinesis still seemed to work and she drew the chalk shakily up to the board. Maybe if she just wrote her lines like Trixie wanted...maybe she could escape this. Maybe Trixie would go easy on her- The chalk dropped to the ground as a wicked sensation of pleasure shot through Twilight's frame. No...she wasn't...she couldn't be!

Trixie had pried the chubby cheeks of Twilight's bottom apart, and was now daintily dabbing her tongue at her most secret, forbidden little girl hole. Trixie grinned viciously, giving Twilight's left cheek a firm 'pat'

"Lines Twilight, Lines. "She called, and Twilight tried to pick up the chalk again, whimpering all the while. The class had gone quiet- the only sound in the room was the chalk scraping against the board, and the hot, lewd squelching sounds of Trixie feasting on Twilight's tight little tailhole.

"MMmm, you taste so sweet, Twilight. You've got the most delicious bottom I've ever had. " Trixie hissed in a husky whisper, forcing Twilight to turn even darker shades of red.

"You didn't know I knew this about you, did you? This little fantasy about being a bad girl...being punished in a class room of your peers...being spanked like the naughty little filly you are...and you certainly didn't know I knew about your number one, dirty, naughty little kink, did you? This is soooo taboo...how dare you call yourself a good little girl. You know the saying, Good little girls are just naughty little girls who haven't gotten caught- and you are a VERY naughty little girl, Twilight." Trixie asked, leaning in to plant a slow suckling kiss right over the shuddering little opening between Twilight's cheeks. The purple unicorn moaned helplessly, clutching at the desk underneath her. Trixie had won. They both knew it. Wasn't an hour up yet? How long could she resist at this point?

Trixie spread Twilight's cheeks widely, and pressed her muzzle in, kissing and slurping, probing her tongue into Twilight's bountiful rump and listening to the embarrassed sounds of pleasure coming from the ponies other end. Her tongue swirled around, clockwise, counter clock wise, probing as deeply as it possibly could, while Trixie examined the twin globes of Twilight's upturned bottom. Two plump, perfectly bouncy hills right in front of her eyes. Her nose was pressed against the little dock under Twilight's tail, and she grinned at every little twitch Twilight made from one of her probing kisses.

"That's right...give in....you love having your butt licked and kissed...toyed with...spanked...it's driving you crazy, Twilight. We both know it...such a naughty, naughty little girl..."Trixie whispered, and grinned triumphantly when she felt Twilight shudder and squeal, shaking helplessly as her orgasm rippled through her. It had crept up on her like a pouncing lion. Secretive and sneaky, upon her before she could bat an eye. It wasn't the sharp, and intense sensation of a vaginal orgasm, nothing had been touching her little pleasure button, but it was an orgasm none the less- a spike of sensation that flooded through her frame, leaving her gasping and panting for air.

"OH...oh my goodness...did you just cum without permission? You really ARE a naughty little filly! Class! Class pay attention! Twilight, here, just came without express permission from the teacher!" Trixie called out. The class returned to its rowdy state, cheering and laughing, giggling at the poor humiliated mare. Twilight buried her head in her arms with a whimper of embarrassment. She knew, somewhere deep down, that this was all fake- an illusion of Trixie's design, but she felt so swept up in it. Everything felt so real, she could smell the chalk, the wood of Trixie's desk, everything.

"Now, if you'll all pay attention-"Trixie announced, drawing her hoof down to Twilight's privates, where she lewdly tugged at one of the girl's puffy, aroused lips. Pulling it to the side, a little gush of cum started to trickle out and Trixie grinned wickedly.

"Do you feel that, Twilight? How did you get so sticky down here, hmmm? Did you cum for me, Twilight? Did I give you permission to do that? I think that deserves another tongue lashing. " Trixie whispered boldly, positioning herself directly behind Twilight. She started with a gentle kiss to Twilight's right rump cheek, then the left. Slowly, ever so slowly, she angled those suckling, teasing kisses closer and closer to the dark divide that split her cheeks in two. No, not again! She couldn't take another tongue lashing! It was so embarrassing...But Trixie didn't seem to care. She went to town, burying her muzzle between Twilight's plump perfect cheeks, and kissed lewdly at that naughty little opening.

Twilight threw her head back and moaned, shuddering as ripples of pleasure raced through her, over and over and over again. How did Trixie know? How could she have possibly known about Twilight's little rimming fetish?! How long had she known? Twilight had never managed to bring up the courage to approach Trixie about it, and now she was kissing her bottom like it was going out of style! The unicorn shuddered again, squeezing her eyes shut.Nonononononono no no nooooooooooh God, YES!!!

Trixie paused in her kissing, pulling back with a grin as Twilight shuddered helplessly, clinging to the desk while her body rocked back and forth.

"You naughty little filly...is that twice? Is that another little orgasm you had, all from me touching your dainty little tailhole? You filthy little slut.."Trixie hissed, forcing Twilight to arch out with another whine. Why wasn't this over already?! How much longer did she need to hold out! Not that it mattered anymore, she'd already lost two points for having an orgasm. Two orgasms, really, and without permission. She really was a naughty little filly.

"Alright, Twilight. We have five minutes left. With the end of our time, I want you to write me a paper on how naughty you are. How many spankings you need for next time, and a comprehensive plan to lose at least five pounds in the next two months. Your bottom is absolutely huge, and I don't know that I can afford to order extra wide seats for my class room. "Trixie hissed. Twilight whimpered quietly, even though the class room was already starting to fade away. Things were getting darker and darker, and the laughter of the other kids seemed like an echo now. The dark wooden desk felt soft under her touch now, returning to her bedspread and her limbs felt tired and stiff, but fully functional. She climbed up onto her bed with an embarrassed whimper and clutched her pillow to her chest, feeling the cold sensation of Trixie's cooling saliva on her rear end.

"H-how...how did you know about..." She whimpered. Trixie, who was a silhouette in the darkness, flashing a devastating smile.

"A magician never reveals her secrets, Twilight. But you loved that, didn't you?" Trixie hissed. Twilight gave only the subtlest of nods, blushing furiously in the dark, and Trixie grinned.

"It was my secret weapon...I figured I'd end up using it eventually, and now is as good a time as any. So, lets see...that's two orgasms without permission, that's 2 points each, meaning your down by four points. It's 6 to 9. You're gonna need a miracle to win, Twilight." Trixie grinned. Twilight grumbled quietly, and pulled the blankets up around her shoulders...well...she tried to. Trixie stopped her with a playful nudge from her hip.

"On your tummy, sweetie." She whispered. Twilight felt her cheeks redden, and slowly, she did as she was told- rolling over on her tummy sheepishly.

"A-Aren't you tired yet? The round is over..." Twilight whined. Trixie shook her head, leaning down to press a loving kiss on the left cheek of Twilight's bum, then the right.

"First of all, I need to kiss these to make them better. I wasn't kidding when I said you had a big butt, Twi, it's gonna take a while. And two, I didn't know I could make you cum just from kissing your behind...I'm going for a Hat Trick. " She grinned, leaning over to plant another kiss on the supple expanse of Twilight's cheeks. The purple unicorn moaned quietly, squeezing her eyes shut as the kisses continued. It was going to be a long night, which was good, since Twilight needed some time to figure out just how she was going to win this game.
