Chapter 1

Teaching With a Broken Abacus
-by Drace Domino

Teaching conferences were always the most boring thing Principal Celestia had to do as an educator, and without Luna to join her this one was bound to be the worst. Teachers from all over the district and across a half dozen schools all packed into the same convention center, all of them listening to changes in statewide policy and making sure they were all on the same page. For the past three hours Principal Celestia had been forced to sit listlessly in the back of the room while tapping on her phone, scrolling past images that were sent to her that she could sadly not act on anytime soon.

A picture of her heavily pregnant sister, wearing a sexy bit of lingerie and giving an enticing look towards the camera. Another picture of Luna, this time laid on her back with her belly eclipsing her face, her thighs spread and her pussy exposed and spread. Yet another - this time with Fluttershy in the image, blindfolded and gagged and with the words “Waiting for Mistress” scribbled across her yellow bust with a marker. Principal Celestia gave an audible grunt more than once throughout the conference, and several times she had to shift her legs back and forth, crossing her knees and trying to wedge an erection down to a point of comfort. It...didn’t even begin to help.

“...and if everyone will turn to their binder on chapter seventeen, subsection forty-five…” The voice from the head of the room droned on, speaking over the heads of nearly a hundred separate teachers, principals, and even a few overprotective parents. Celestia pressed her binder harder into her lap, yet still couldn’t stop from letting her thumb pass along her phone again, swiping to the left to reveal another enticing picture. The bound and gagged Fluttershy with a toy stuffed in her ass, and Luna’s pregnant belly resting on the base of it, slowly pushing it in deeper. This. Was. Torture. And the droning from the head of the room didn’t make it any better. “...there’s been a new change of policy regarding student dress code on a statewide scale. Schools will now be allowing shorter skirts, but only, and I quote, if the student can pull it off.”

With a grunt, Celestia finally pushed herself up from her seat and snapped her binder closed. As the luminous-haired woman stood there were quite a few that turned in her direction, either because she was one of the hottest under the roof or simply because she had been giving horny grunts for the past hour and a half. As they all gazed at her, up to and including the speaker, Celestia merely gestured behind her and gave a tiny, bashful murmur.

“I...I just need to use the restroom. And make a call. And get a drink.” A long pause, broken only by an awkward cough somewhere in the room. “And maybe a snack. And sharpen my pencil. And...I’ll be right back.”

As Principal Celestia stumbled her way from the conference room and into the hall, the rest of the teachers all went back to listening to the boring lecture about policy and processes. All but one; however, whom had been glaring at Principal Celestia since that tall, attractive, beautifully-haired bitch first stepped into the conference.

It was only a few seconds later that figure stood up and left just as swiftly, wordlessly and with an irate glare set within her gaze.

***

By the time Celestia slipped into the restroom, the poor woman was ready to burst. Her little sister and that submissive pet Fluttershy were certainly going to get it as soon as she arrived back home, and the woman was planning fitting punishments for each. Luna was far too heavily pregnant for her older sister to be rough on her, which meant that the treatment she received for this teasing would be worse - forced to sit comfortably in the living room reclined and well-taken care of. Given food and drink and everything she could want...while being forced to listen as Celestia tore into Fluttershy like a ferocious beast in the bedroom. That would certainly teach Luna a thing or two about how naughty it was for a pet to tease her mistress!

But for now, Celestia was having difficulty tending to her own needs. As she entered the restroom the principal let her phone rest on the countertop, just as she opened the front of her pants and allowed her enormous pearl pink cock to flop forward. As it slapped to the marble of the sink the educator gave a lewd grown regardless of the fact she still hadn’t checked to see if she was alone - at this point, she didn’t care. Her cock was pulsing and throbbing with weight and desire like she could barely imagine, and there was no reasonable way she could wait until this stupid conference was over to sink it into her sluts. Hell, at this rate, it’d be dangerous to drive with that massive thing hindering her mobility. There wasn’t a trace of shame as Celestia slapped her palm against her cock and gave it a few hearty pumps, focused on getting herself off as quickly as possible so she could make her way back.

All she needed was a few minutes uninterrupted. All she needed was a bit of time to herself. Apparently, it was simply too much to ask.

“Well, well, isn’t this quite a sight to behold.” Abacus Cinch’s voice was as cruel and condescending as ever, ringing of the superiority that she so naturally clung to. Celestia gave a loud yelp as she spun around from the sink, leaving her phone on the countertop as she fumbled to stuff her cock back inside of her pants. It wasn’t an easy task considering the girth and excitement ringing through her, and before long she had been forced to settle with covering her prick with both hands and nibbling at her bottom lip, hoping that Cinch couldn’t see too much. By the smug look on Cinch’s face, she had seen enough. “I always knew you were a troublemaker, Celestia. Unfit to take care of students! Unfit to run a school!”

“...I’m not the one that was forcibly transferred by the school board, Abacus.” Celestia murmured, and lifted her brow. There came a certain point that the principal of CHS realized just what she was doing, and that she had absolutely no reason to bother covering herself. She simply stood with her cock hanging free and open, allowing every inch of that nearly foot-long prick to dangle exposed. It was a hell of a sight for any woman, and for a prude like Cinch, Celestia could only imagine it was the greatest thing she had ever seen. Sure enough, Celestia caught the bitch glancing down at it once or twice, and that only ensured that she’d remain hard well into the conversation. “Oh...I’m sorry. Not just a transfer. You had to take a different position, didn’t you? It’s Secretary Cinch now, right?”

“Y...You...you, miserable, arrogant cow!” The former principal of Crystal Prep’s cheeks took on a blush of anger, and she rose a hand to point squarely at Celestia’s nose. “I’ll see to it that you’ll be removed from your position for this public display of indecency! Perhaps I’ll position myself to take over for you, and give those unruly brats of Canterlot High a real education! Why, I could even retake the reins on Twilight Sparkle’s futur--” It was at about that point that something caught Cinch’s eye, and she tilted her head to look past the other woman.

Almost a shame, as Celestia’s didn’t have the chance to tell her that Twilight Sparkle was the prize slut of CHS, and very near the birth of her first child. Instead, Celestia was forced to watch with wide eyes as Cinch snatched a hand to the countertop, picking up the phone that the other woman had been using as masturbation fodder for those brief few seconds. A squeak of surprise ran from Celestia as Cinch greedily pulled it close, her voice erupting into laughter as she looked at the images laid out before her.

“Oh, dear me, this is simply too precious!” She gave a boastful roar of pleasure, and stepped back to avoid Celestia’s sudden flailing grabs, each of which made that massive cock swing back and forth. “Images of your very own sister, Celestia?! And my, my, my, how pregnant! Don’t...don’t tell me that...that you’re…”

There were women that might have balked at the reality, that would have cried out in surprise or disgust at the notion that Luna was carrying her sister’s child. But from Cinch, Celestia only received triumphant laughter that pierced the restroom with her cocky delight.

“Ohhh, ho ho ho! Absolutely marvellous! I’ll have your job, and I’ll be able to hire my own vice principal!” Cinch was on top of the world, beaming and flipping through the images on the phone as Celestia fumbled and failed to reclaim it. “I wonder who I could hire to fill in for your little sister? Apparently, the only job skill they’d need is being a worthless, slutty little trollop--”

Celestia had been kind up to that point. She hadn’t forced Cinch from her presence, she hadn’t pushed violently to reclaim her phone, and she didn’t even make fun of her profoundly stupid first name. But as soon as Cinch swung for Luna, it was the end of the argument. The phone in question went clattering to the floor as Celestia pushed ahead, slamming her figure into Cinch’s own and pressing her against the restroom door. She held one arm against Cinch’s chest while another held the bitch’s wrist, keeping it pinned to the wall as she leaned forward. Most scandalous of all was the weight of Celestia’s cock, still hanging from her pants and now pushed down, squeezed right between Cinch’s nylon-clad thighs, trapped on both sides by surprising toned, fit muscle. As Celestia held Cinch down and forced the other woman to feel her weight, the CHS teacher hissed from the back of her throat in a protective, fierce tone.

“Don’t go after Luna just because nobody wants your miserable, cranky pussy.” Celestia growled, her tone sharp and fierce and her eyes narrow. As soon as she said the words there was a tiny spark of humor at the back of her throat, and she offered a little chuckle before shaking her head in teasing fashion. “Heh. That’s it, isn’t it, Abacus? Jealous that Luna gets fucked. Jealous that Luna gets knocked up. Jealous that she has someone to send dirty pictures to, and you have to go home and pretend some silly toy is a real cock inside of you.”

“H...How...how dare you, Celestia, I…”

“Must be rough.” Celestia pressed, ignoring Cinch’s resists and keeping her effectively pinned. She allowed her full chest to squeeze all the harder to the older woman’s, and she let her cock glide back and forth, grinding in between those thighs that kept it locked. She was tenting the back of Cinch’s skirt with the tip of her dick, and riding atop her shaft she could feel a the bitch’s panties, wet and warm despite her protests. “How long has it been, Cinch? How long’s it been since someone could stand looking at you long enough to let you rub that old cunt on their cock? How long’s it been since someone could even cum in the same building as you?”

“Y...You...you’ve crossed a line...I’ll see you expelled from service, I…”

“I’ll make you a deal, Cinch.” Celestia purred, absolutely unphased by the older woman’s threats. She drew her mouth in close, let her lips near the edge of Cinch’s ear, and closed her eyes as the stiff, perfectly-positioned but heavily-sprayed hair of the other woman passed her forehead. Her whisper was cruel to be certain, but it served it a purpose. It’d help her protect her little sister...and it’d give her something marginally better than her hand to get off with before going back to the conference. With a coy smile, Celestia proposed her wicked little offer. “Forget what you saw here...and I’ll fuck you right now. First cock you’ve had in ten...maybe twenty years? Wouldn’t that be worth shutting your bitch mouth for once?”

Celestia could tell that the offer was tempting, all thanks to the trembling that Cinch was doing against her. The bitch hadn’t even tried to fight back the entire time that Celestia spoke, no doubt enjoying the fact that a cock was closer to her pussy than it had been in decades. Ultimately, Cinch didn’t even have the chance to speak before Celestia merely assumed that she was happy to take her up on the offer, a hand locking around Cinch’s wrist as she pulled her across the restroom and back towards the sink. Cinch stumbled on her heels as the other woman moved her, again putting up no resistance as she was lifted to the edge of the marble and her ass was laid flat against it. Celestia’s smirk was enormous and smug as she worked, helping herself to slip her hands underneath Cinch’s pencil skirt and pulling it up around her waist, just before she shoved a hand to grasp at the boring cotton panties covering the other woman’s pussy.

“Y...You...you’re…”

“Shut the fuck up, Cinch. Or I’ll leave right now.” Celestia grinned as she ripped free the panties of the other woman, pulling them past her nylon-clad legs and tossing them casually over her shoulder. Her hands went next to Cinch’s chest, fingers grasping at the button-up sweater and pulling it open with a sudden, switch gesture. Buttons went snapping off to clatter to the floor and it wasn’t long after that Celestia yanked the other woman’s bra down, letting it fall trapped underneath her surprisingly impressive tits. It was a shame, really, Cinch had a good body and a pretty, fuckable face. Too bad she was such a relentless cunt all the time.

“I...I...goodness...you…” Cinch held a hand to her forehead, her glasses hanging on the tip of her nose as she was left spinning in a sudden flourish of desire. She despised Celestia like few others, and yet here she was with her legs spread, one of them moving to drape across her shoulder while the other dangled from the edge of the sink. Her pussy was raw, wet, warm...a reflection of the heat that was clinging to her senses and making her feel desperately short of breath. Just as Celestia stepped up and finally grasped the base of her impressive pearl-pink meat, Cinch looked down at the tip and gulped in nervous tension. “It’s...enormous…”

“Any cock would look big after you haven’t seen one in twenty years.” Celestia replied with a smirk, just as she started to swing her length up and down. She rose it high and then let it crash down against Cinch’s lap with a heavy slap, the bottom of the shaft grinding against the woman’s tender, sensitive folds. “But...yeah. Guess you can say you’re about to make up for lost time.”

Celestia took great delight in slapping Cinch’s pussy with her cock a few more times, lifting it up before swinging it straight back down, each time sending a noise of flesh clapping to flesh through the room, as well as Cinch’s whimpering groans. The bitch was so wet and ready that Celestia could smell her arousal from there, and when she swung her length down low enough to threaten penetration an enormous grin spread across her face. With Cinch wringing her hips from side to side in an attempt to gain an inch of cock without actually asking for it, Celestia slipped a hand up around the other woman’s throat, giving her a squeeze and showing her dominance as she finally spoke.

“You keep your whore mouth shut about my sister.” Celestia delivered that final command, complete with her bare hand moving to give Cinch’s hood one last slap. “If you don’t, this hungry cunt of yours is never getting my dick again.”

And with that, Celestia shoved forward to give Cinch a firm idea of just what she’d be missing. If she was lucky, the former head of Crystal Prep would leave these day with an overflowing creampie and the promise that Celestia would pound her again when she felt like it. If she was stupid and ran her mouth...then what happened in that restroom was going to be nothing more than a reminder of the last bit of good sex she’d ever have. There was no denying the fact that the two women hated each other, but Celestia was banking on the guess that would only make it all the more exciting. For her part, she was relishing the look on Cinch’s sophisticated face as the massive member plunged deep inside of her. And for Cinch’s, considering how soaked the mature woman’s pussy was and how frantically she was moaning and twitching, it seemed like it was working for her, as well.

With a triumphant smile Celestia kept one of Cinch’s legs lifted and braced over her shoulder, slamming forward with hot, hard thrusts and caring nothing for any semblance of foreplay. Cinch had a wet hole worth jamming her dick in - there was no other debate that needed to happen before she fucked them both into a state of bliss. Her hand tightened around Cinch’s throat to maintain her dominant position and she let her other palm squeeze at one of the woman’s tits, manhandling them rough and heavy and delighting in leaving fingerprints on her flesh upon pulling them away. Each slam of her hips sent a wet noise of bliss through the air but it was hard to hear over the sound of frantic flesh clapping to flesh, not to mention the depraved, slutty moans that started to pour from Cinch’s throat. Even with Celestia’s fingers locked around it, she wasn’t having any trouble making one hell of a scene.

“Ha! Listen to yourself, you miserable cunt!” Celestia grinned, and thrust forward hard enough to lodge herself down to the base. Her hips rolled from side to side as she felt Cinch’s pussy grind against her shaft, teasing the walls and seeing just how far she could jam herself forward before the bitch broke. “I bet everyone in the conference can hear you moaning like a miserable twat. Everyone knows what a slut you are underneath all the bullshit. Maybe they’ll be happy for you, I’ve never met a bitch that needed to get laid so much in my life.”

“I...fucking hate you...so much…” Cinch hissed from the back of her throat, the words muffled and raspy from the grip Celestia’s had on her throat. Even still, she gripped the side of the sink and kept her legs spread, her pussy spasming in desperate attempts to milk that enormous member. “...you’re...everything that’s wrong with CHS...with education itself!”

“Maybe. And I sure don’t doubt you hate me.” Celestia shrugged, just as she resumed slapping forward. She pulled her prick back only before lunging in as deep as she could manage once more, making Cinch squeak in between her taunts. “But that’s not going to stop you from letting me knock you up.”

The look in Cinch’s eyes was a twisted blend of fear and shame, disbelief mixing with the desperation of her situation. She parted her lips several times as if it offer some semblance of a refusal, and yet she failed on every step as Principal Celestia just kept fucking her. Tears were at the corners of Cinch’s eyes as Celestia continued, and she was forced with the heavy weight of a truly humiliating revelation - she was so hard up, so desperate for a good cock, that she would gladly let this horrible monster of a principal put a baby in her.

And she would cum like a maniac throughout it all.

Cinch was thrown into spasms of pleasure as Celestia started to jam forward harder and harder, lunging herself down to the base just as she tightened her grasp a little further on Cinch’s throat. At a certain point the Crystal Prep alumni felt her air grow too short in supply to properly scream, which was probably better for the perception everyone in the conference hall had of her. Her cheeks were overtaken by a tremendous blush and her glasses bounced from her face and down to her tits - only to bounce once more from her chest and to the floor below, striking the tile with a light shattering noise.

Celestia wasn’t just fucking Cinch, she was going to ruin her for anyone but herself. As the miserable bitch fell into waves of orgasms that had been decades in the making, Celestia smiled from ear to ear and gave her a few last short hatefucks to seal the deal. Her balls were desperately eager to unleash their torrent after all the teasing images Luna had sent her, and now Cinch was going to reap the reward. It was just another reason Cinch should be nice to her little sister, after all, she was going to enjoy the benefit of the cum that Luna had done the hard work in earning.

Principal Celestia didn’t give Cinch any warning when her climax was upon her, in part because she didn’t want the cunt to have any chance to push her away. Cinch was just left twitching as the torrent began to unleash itself, and those long-neglected nethers were painted with the rich, warm cream of her rival. Celestia trembled with bliss as she hilted herself and filled Cinch was load after load of spunk, leaning in close and looming over Cinch like an arrogant shadow. She gazed down into the eyes of the other woman, slowly released her fingers from around Cinch’s throat to show the gentle bruising underneath, and whispered as she gave one last thrust with a tiny final burst of cum.

“You’re going to be a fucking horrible mother.” Principal Celestia offered one last cruel tease, just before pulling her dick free. When she did so, the momentum that overtook the blushing, crying Cinch was tremendous. The yank of Celestia’s cock sent her slipping right off the sink, landing with a heavy thud to the tile below, her knees bruising and her rump bouncing to the floor beside her broken glasses. Principal Celestia was already tying her belt once more and bending over to pick up her phone, raising it just long enough to get Cinch in frame in all of her ashamed, stunned glory. A soft click filled the room, and Celestia smirked. “Sometime to send to Luna. That oughta teach her not to tease me.”

With that, Principal Celestia merely...left. She spun on a heel, hummed to herself, and made her way down the hall to rejoin the conference. She left the former head of Crystal Prep kneeling on the floor, her nylons marked with sweat and cream, her clothes torn and her glasses broken, and an overflowing creampie flooding her pussy and dripping to the tile below. Abacus Cinch trembled, her hands bracing to the sides of her head as her heart raced and she tried to make sense of it all. This was...a nightmare. But a nightmare that had given her a satisfaction that she never imagined before.

“T...This...oh my…” Cinch murmured, and as she started to come down from her high gazed at the cum-matted patch of hair just above her pussy. She could feel it slosh around within her, feel how deeply Celestia had jammed her cum. From the images of Luna, it was clear that Celestia was...potent, and she had just given Cinch a healthy dose of it. With a panicking whimper rising in her throat, the weight of Cinch’s situation began to sink in. “Oh...no...no no no…”

Abacus Cinch learned quite a few things at the teacher’s conference. She learned that she’d need to be nicer to Celestia if she ever wanted to feel that good ever again. She learned that an angry woman didn’t give a damn about pulling out of a cunt she didn’t respect. She learned that her glasses couldn’t survive a fall from the sink. She learned that the conference hall’s main restroom was close enough that every teacher in attendance heard what a whore she was.

But mostly, she learned one very important lesson.

Nobody threatened Celestia’s pregnant little sister.

The End.

Author's Note

If you're one of my Twitter pals, you probably know I have a fondness for Principal Cinch. I'm fully aware it isn't something that a lot of people share! But I think if we can all get behind her being made into a hungry slut for futa cock, it might just help us heal this fractured world.

Big thanks to Ani for supplying some lovely art to go along with this chapter! Make sure to give them a follow, too!
