Everyone in class paused, looking around for the source of the loud 'thud!' that had just interrupted the lesson. Nobody paid any attention to Sunset, her face going from one shade of her hair to the other as she rubbed her knee. After a minute, Cheerilee shrugged and continued the lesson.

Sunset tried to focus on the lecture, she really did, but then Lyra and Bonbon started making eyes at eachother again and her mind went right back to their cute faces asking her to stud for them. She jerked her leg again as her erection crawled further down the rough material of her jeans, barely avoiding the desk again, trying to harden in that severely confined space. Her balls were, if anything, worse, barely contained by the denim under her skirt, throbbing and filling while she tried desperately not to think about plunging into Lyra's tight snatch with Bonbon sucking on her balls so Sunset could properly knock up her girlfriend.

There was another 'thud,' but this time it was obvious to everyone.

"Sunset Shimmer, are you alright?" Cheerilee asked, staring at her student whose head had just impacted her desk with force.

"...Not really. May I be excused to the restroom?" Sunset asked, voice muffled by her desk, sounding more miffed than sickly.

"Of course. Write down the homework on the board if you haven't already, in case you don't make it back by the bell." Cheerilee nodded, suspecting feminine problems... but quickly revising that when Sunset stood up and limped out of the room. Her eye twitched, wondering what shenanigans the Rainbooms were up to now and why it involved shoving an entire foot plus of salami down Sunset's jeans. The teacher's traitorous twat suggested it might be a magic salami full of salty miso for feeding thirsty pussies after long dry spells, and she had to fight down a blush before continuing the lesson, banishing the silly idea.

~~~

Sunset sighed in relief as she finally managed to peel her jeans away from her bait and tackle, the cool air heaven on her hefty balls. She could even ignore her erection, rising slowly, pump by pump, now that it was free from its prison. At least for a moment.

"Ugh, I really should've stopped to talk to Rarity." Sunset groaned, taking a seat on the closed toilet and leaning back, the cold porcelain soothing her eager nuts as she regretted running out of Pinkie's as soon as it was polite and spending all day Sunday masturbating and procrastinating over her magic diary.

"No thanks to you." She grumbled, glaring down at her throbbing horsecock. But, with a sigh, she grudgingly wrapped a hand around the base, scooching down further so her balls could hang free while she wanked. "Pain in the ass fucking dick." Sunset angrily choked her chicken, sliding her hand up and down the dry skin beneath the medial ring while the other reached for her balls to coax out some lubrication-

"These aren't my glasses!"

"GAH!" Sunset nearly jumped- as it was, she scooched back on the toilet seat away from the thing that had lifted her balls suddenly. Pinkie's face, as it turned out, the pink girl turning and pouting as Sunset ruined her joke.

"Hiya Sunny! You look a little pent up!"

Sunset spent a moment catching her breath and watching Pinkie's eyes follow every bob of her shaft- which wasn't helping her erection any.

"Pinkie. Aren't you supposed to be in class?" Sunset finally asked, for lack of anything better to say.

"Aren't you?"

"Touche."

"Gesundheit."

Sunset opened her mouth... sighed, and closed it on that train of thought.

"What are you doing here, Pinkie?"

"Helping you get unpent." Pinkie answered, reaching forward without prelude, request, or hesitation, to slip her hands under Sunset's balls, warming them after the time spent on cold porcelain, rubbing and tugging them gently. Sunset could only stare, incredulous, at the pink girl's forwardness, letting Pinkie pull her down to sit, her balls hanging off the side again as Pinkie massaged them.

"I'm not sure-nnh!" Sunset tried to object, but a darting pink tongue on her medial ring interrupted her attempt, her teeth gritting to hold in a moan that would probably alert half the school. Her teeth stayed grit and her hands gripped the bars on the side of the stall as, after a slurp and a giggle, the tongue returned for the main dish. It never licked, merely lapped, moving from place to place erratically, punctuated by the occasional kiss as Pinkie tried to cover every bit of the massive shaft one spot at a time, somehow rapidly wetting every bit of it with her spit while her hands continued to slowly, gently massage her sensitive testicles.

Once the shaft was shiny, she moved onto the head as one hand left Sunset's balls to tease her pussy- Sunset noticed, felt the magic as it surged in her prick, but she was too aroused, too impassioned to sense its nature or effects as the spell manifested in a spurt of her copious pre-cum. Right into Pinkie's pursed lips, where it was sucked away without a trace, the pink girl licking her lips as she pulled away, giggling as the spell slipped down her throat, readying it for Sunset's schlong. Not that Sunset knew that. Pinkie was smarter than she let on though, and remembered what Twilight had done last night- she could now deepthroat almost anything with ease.

"Hm, tempting." She said, seemingly to herself, "But I think it's time to get this show on the road!" All it took was a quick swipe of her tongue, wetting the last untouched place on Sunset's cockhead, and a quick squeeze of her throbbing balls.

"Oh god, Pinkie-! I'm-" Sunset's hoarse words(1) were cut off with her pleasure as Pinkie let go, leaving her right on the edge. It took a moment for her to recover her wits and look down towards the action- and then up, past the swinging stall door to a tight pink pussy, spread by two fingers and framed by a pulled up skirt, with a lewd smirk to top it off as Pinkie offered her pie. The smirk only widened as Sunset's sclera blackened and her irises began to emit a demonic glow, a growl following her out of the stall. Short-clawed hands took hold of her bubbly cheeks, pricking them painfully, but not quite enough to draw blood, spreading her cheeks and then pressing them together around the spit-slicked cock, pre drooling all over Pinkie's ass.

"Oh Sunny-!" Pinkie gasped, both her lower holes tingling as the magical pre readied her to take every inch of Sunset's enormous horsecock, new nerves springing into existence and immediately being stimulated by the clenching of her own greedy orifices, "Stop teasing meeeeee!"

"Hmph. Such a slut." Sunset's voice echoed unnaturally, even for the bathroom, the sound suffused with power and sin. "MY slut!" She growled possessively, one hand drawing back to- *SMACK!*

"Ohmigosh." Pinkie cried into her pinkie, trying to keep her voice down as a single slap on her ass almost sent her to heaven. *SMACK!* "Ughgohgh." Pinkie descending into a gagged moan, her entire fist in her mouth as Sunset attacked the other cheek, chuckling evilly as she sent Pinkie to the edge and refused to let her go over.

"Mhmm... My silly slutty pink pet." Sunset said, her hands rubbing over Pinkie's cheeks as she continued to hotdog her bodacious buns, spreading her pre-cum all over them, "You want it, don't you? You want to lose your virginity to me. To have my fat cock up your foalhole. Want me to knock you up? Make you a proper broodmare? No. Not that yet. We have things to do after all. Lots of things."

Pinkie didn't care what Sunset did to her as long as she'd let her cum! She thrust her hips back at Sunset, trying to pull her cock down enough to go in, moaning into her fist that was going far deeper than a fist should. Sunset giggled, low and dark, as Pinkie's pie pressed against her head, thrusting with a deliberately sloppy motion, pressing the full length across Pinkie's clit as it slid up her belly and poked her wobbling tits. Pinkie had to stop, helpless, as she was forced to edge again, but not over, Sunset pulling back as she squealed through her teeth at the teasing. The head met her honeypot once more, but Sunset merely left it there, only the lightest of clawed grips on her hips assisting her aim. Desperate, Pinkie pulled her hand free of her throat-

"No hands." Sunset demanded, gripping Pinkie's wrist and putting it on the sink, "If you want me to take your cherry, do it with nothing but your hips."

"But Sunnnnnny-!" Pinkie whined, but her objection was cut off by another slap on her ass, forcing a gasp from her mouth as she panted with need, her paramour merely chuckling darkly at her desperation. A desperate lunge back, another slip, and Pinkie was hotdogging Sunset's wiener once again, forcing a groan of both pleasure and desire from Pinkie- Sunset gave her another spank for the failure as she drew back again.

"Grrrrr! Stupid cock! Get in me!" Pinkie growled, twisting her hips once, twice, three times- the head pressed in a little deeper, and she gasped for joy, twisting once more- and then lunging back. A part of her remembered that her hymen breaking was supposed to hurt, but it was by far drowned out by the parts of her cumming their brains out as Sunset's flared prick spread her wide and deep, pressing all the way to her cervix and almost through. She thought that was supposed to hurt too. Probably magic, the part of her mind that never turned off thought while the rest of her was busy jerking, twitching, and clenching in a seemingly endless orgasm around the throbbing horsecock that really shouldn't fit in there. Someone was screaming, too, and she kind of wished they stop because they were being really loud. Oh hey, that was her too. Huh.

Eventually, after a thorough re-lubing of Sunset's cock with her squirt, along with the floor and her feet, Pinkie came down, panting, resting her forehead against the cool porcelain of the sink. The monster inside her pussy hadn't moved, merely throbbing there, a bit impatiently, maybe. She managed to raise her eyes to the mirror, meeting those glowing demonic irises as Sunset gazed down at her conquest, both smug and possessive. The ginormous shaft flexed, and Pinkie was almost sent soaring again, muscles she was sure should be sorer clamping around her invader as it pressed at her innermost gates, hot pre spurting against her insides.

"Glad you had fun, Slut. But now, you're mine, and I would like to cum. You've got another three inches to take, get to it." Another slap on her ass pressed Pinkie back a little- yes, there was more cock back there, she noted, giggling through her gasp as it pressed further against her final gateway.

"I'll get it, Sunny-" *SMACK!*

"Mistress when I'm in you, Slut."

"Yes Mistress." Pinkie managed when she regained her breath, and her senses after another flex sent her to a rolling orgasm. With a grunt, she forced herself to concentrate, pressing her hips back again, forcing Sunset's broad, flat head against her womb. Her teeth grit, forcing her way through the impossible pleasure assailing her from that last gate into her body. With a sudden bout of inspiration, she twisted her hips, and felt herself open slightly. A spurt of molten pre splashed through, and she lost her progress to another clenching orgasm as it burned her womb, unable to focus as Sunset's cock flexed and spurted inside of her.

"So pathetic." Sunset sighed, giving Pinkie's glorious rump another handprint before finally deigning to lean down and press herself against her pet slut, reaching around and under her shirt to wrap her claws around Pinkie's hanging breasts, tweaking the nipples with their sharp points as she whispered into Pinkie's ear. "I'll have to train you thoroughly until you can take me to the hilt every time. C'mon, Slut, knock knock. Let me into your womb."

Pinkie squealed, squirting hard enough to hit Sunset's hanging cum-factories, as the demon gave her an encouraging thrust, almost pressing herself in before pulling back to merely kissing her cervix again, leaving Pinkie to ride out the aftershocks, almost purring as her shaft was massaged by Pinkie's tight cunt. Her eyes widened in surprise as Pinkie pushed herself back, still clenching and squeezing in orgasm, forcing herself farther onto Sunset's thick fuckstick with a snort, twisting and pressing herself deeper even mid-squirt, further dousing the hefty nuts that were going to fill her up as soon as she let Sunset in.

But the demoness had a limit too, Pinkie found out, as claws dug into her pudge, and she was yanked back- she could feel the pop as the fat, flared head of Sunset's meaty horsecock plundered the deepest of her buried treasure- she spared a few brain cells to giggle silently at that- and swelled further, locking itself tightly into her womb. Pinkie could feel the heat, the expansion of Sunset's shaft as cum filled it, a whole torrent of baby-gravy headed for her baby-cave, and drew in a breath even as she spared another few brain cells to giggle at that.

~~~

Half the windows in the school shattered. Fluttershy's classroom of residence rapidly became a chaotic mess, animals racing and jumping and flapping about everywhere, while the girl herself tried to calm them and cover her ears all at once. Four other girls also winced as their aural senses were assaulted by the loudest squeal they'd ever heard, in a pitch they shouldn't have been able to. Outside a certain bathroom, a certain vice-principal that certainly shouldn't have been peeping through the bathroom door and most definitely shouldn't have had her hand down her pants at work, wondered why Pinkie's mouth was open and no sound was coming out.

~~~

Sunset groaned, grinding her hips against Pinkie's plush buns, even with one side of her lips curled in a smirk as her silly slut screamed her pleasure and squeezed her spurting flare. One clawed hand wrapped around her middle, rubbing against pudge before finding the hard ridge of her flare through Pinkie's flesh- and then it was lost as Pinkie was filled, her belly growing as her womb swelled with cum. Pinkie's scream cut off with a squeak when Sunset's shaft twitched, firing a larger salvo at the simple knowledge that she was swelling the cheerful pet into a psuedo-pregnancy. In the midst of orgasm, flush with lust and power, Sunset's hand drew lines of fire on Pinkie's belly, tendrils of magic reaching through her flesh and into her womb as Sunset marked her. As Sunset took her hand away from the stretched skin, the fire faded, leaving only her mark drawn in runes, before that faded as well.

With a fanged smirk, Sunset gave one last microthrust, drawing a choking noise from her property and spraying the last of her steaming demon semen into Pinkie's straining womb. Looking up to the mirror, she grinned at Pinkie's glassy-eyed and drooling face, her cunt still twisting and squeezing around Sunset's fat dong in continuous orgasm.

Then her own eyes filled with confusion, as the darkness receded.

"Pinkie? What did I..." she started, then gasped as her friend squeezed at her, instinctively trying to pull back- and failing as her flare hadn't shrunk all the way yet, tugging Pinkie's used womb and sending the pink girl into yet another orgasm, which didn't help the situation at all. Groaning as she was vigorously milked, Sunset desperately tried to remember what stallions had done when she was on the receiving end of having her final gate plundered. Even as she thought, she let herself lean forward and press against Pinkie's back, wrapping her hands around her friend and stealing a grope. Well, that didn't help either, even though Pinkie's bombastic boobies were quite enjoyable to squeeze.

It took several minutes before Sunset felt herself soften, and a few more before her flare shrunk enough to pull free of Pinkie's tight cervix with a pop, sending her into yet another spasm. Sunset shuddered as well, her slick horsemeat sliding easily out of Pinkie's body with a *schlorp* and a heavy *thwap* against her own leg, covering it with even more of Pinkie's juices than before. Sunset bit her lip, watching Pinkie's stretched hole contract rapidly, only a tiny trickle of cum leaking out- Sunset remembered being a fountain the time she experimented with that much cum.

"Pinkie, are you okay? Talk to me Pinkie." Sunset said, putting a hand on Pinkie's shoulder and shaking her.

"Ahm fahhhn." Pinkie drooled, looking up at Sunset with adoration and lust, before sliding back off the sink, forcing Sunset to catch her, letting her to the floor gently and setting Pinkie to giggling. "Myh legsh are noodles!"

"Not surprised." Sunset snrked at Pinkie's giggling and wobbling her legs what little they would move, staring down at her still-swelled belly. She remembered doing that, all of it, but the memories were fuzzy and indistinct, like a dream- and notably lacking the claws, her dark gaze, and the now-invisible runes over Pinkie's womb. She shoved the memories away before she could get hard again, glancing down at her floppy prick, "Hang on a moment, I'll get some paper towels."

~~~

"Oh chill Sunny, it's not like I showed up under your nuts on accident." Pinkie scoffed as she straightened her clothes, now only slightly sweat-stained, "You need to learn to let go sometimes."

"But I shouldn't have lost control like that! At all!" Sunset whined, pulling her own- wait, these weren't her panties. She glared at Pinkie, who merely smirked and turned around, swirling her skirt and giving Sunset a flash of plump pink pantiless cheeks. With a roll of her eyes, Sunset chose not to argue, pulling Pinkie's pink lace undergarments up over her balls and forcing her mind away from the view before her cock tried to break them. "And you still look pregnant! What are you going to tell your teachers? And what are we going to tell our friends."

"I'll tell them the truth- that someone pumped me so full of jizz that I look knocked up!" Pinkie cheered, rubbing a hand over her swollen belly- was it just a bit smaller? Sunset was sure it couldn't be- Pinkie hadn't leaked more than a few drops.

"You can't just tell people that Pinkie!" Sunset argued, zipping her jeans with some struggle.

"Why not?" Pinkie asked, pretending to be confused as she stepped out into the hallway, Sunset limping a bit as she tried to follow- she really needed Rarity's help with clothes this afternoon. She ruthlessly suppressed her thoughts of Rarity helping her in other ways before opening her mouth to explain to Pinkie exactly why not, but was interrupted by another voice.

"Because that kind of talk is inappropriate on school grounds. As were your actions in the restroom." Vice-Principal Luna intoned from the hallway with a stern glare. Pinkie and Sunset winced simultaneously, meeting each-other's eyes to the side, conveying one unspoken word: Busted.

Neither noticed the front of Luna's pants were still slightly damp.

~~~

"So, Sunset." Luna said, looking over her steepled fingers at her former most troublesome student with narrowed eyes. Eyes Sunset tried to avoid, wishing Luna hadn't sent Pinkie away after her lecture about sex on school property.

"Yes, Vice Principal Luna?" She finally answered, scratching the back of her neck reflexively, "Did you have something you wanted to ask me?"

"Yes. Yes I did." Luna responded, still staring at her, giving her another minute to sweat before actually asking. "Where did you get it?"

"Get what?" Sunset tried playing dumb. Luna raised an eyebrow at her. Then the toe of Luna's Mary Jane slipped into the in side of her pant leg and tugged it out, shifting her overtight jeans in such a way as to cause a painful pinch. "Eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee." Sunset's squee was quiet, the sort of sound someone makes when a lobser latches onto their balls full-claw. Which, the part of her brain not focused on the pain thought, is a particularly apt metaphor. Desperately, she unzipped her pants and let the monster free, pulling her abused testicle up out of its vice and letting it bounce free for the moment.

"Youfuckinbitch." Sunset gasped in relief, Luna merely smirking at her profanity.

"I'll forgive that. You really should get more fitting clothes, Ms. Shimmer."

"Rarity's this afternoon." She wheezed as her aching nut got the message to her brain that it was no longer in distress with, to her perception, glacial speed.

"Good. Now, this isn't quite like your usual shenanigans. Where did you get it?"

"Pinkie's party last night. We were discussing things about Twilight's little magic-stealing rampage and I told them about the Dark Magic still latched onto my Core." Sunset started, not even bothering to tuck herself back in, her head leaned back as she stared at the ceiling, consequentially not seeing Luna peeking at her Rod of Virility with blushing envy. "And then Pinkie pulls out a book she called the Partynomicon and-"

"The what?" Luna's gasp of dread, however, did get her attention, "Is it safe? Who has it now?" The Vice Principal now had both hands on her desk, glaring intently- not at Sunset, but past her at something unseen.

"The Partynomicon. I think it's safe. Pinkie put it back in her closet, I'm pretty sure." Sunset answered, warily, totally not sneaking a peek down Luna's shirt, throbbing monster be damned. Sunset started stuffing it back in her pants before it could get any ideas while Luna focused her eyes on her desk, lips moving as she talked to herself silently.

"If... If Pinkie's got it, it's probably as safe as it can be. She's used it before?" Luna looked back up, serious as can be.

"She's got the summoning circle we used stained into the wood under her carpet." Sunset deadpanned, still a little annoyed that she hadn't seen that as a bad sign.

"...Right. That's probably good then. I'll need to have a talk with Pinkie before she leaves today. So, what exactly did you do, Sunset Shimmer?" Luna came back to the topic, her tone a bit warmer, if a little shaken. Sunset stared at her for a full minute, until the stare took a tiny shift back towards hostility and she started talking.

~~~

"So, I think I can probably just ignore it, since we didn't set a time limit or anything." Sunset concluded, grinning... which quickly faded at Luna's unimpressed look, "Or... not?"

"Sunset Shimmer..." Luna sighed, "Cavorting with those from beyond this realm- your own realm excluded- is never a good idea. I cannot give you detention for actions taken outside of school, but I assure you, any summonings other than the completion of the contract you already have will result in dire consequences. Am I understood?"

Sunset shrunk back in her seat, nodding.

"Good. Now, I'll need to speak with your friends this afternoon, but you clearly aren't going to be educated until you have pants that fit, so you will be released for the day. Be sure you come to school in clothes that fit, tomorrow." Luna said, "You may consider yourself dismissed. I advise you head home until your scheduled meeting and give that thing some air."

"Yes Ma'am." Sunset said, biting her tongue under Luna's piercing gaze to hold back her many many questions as she left the room. Luna collapsed on her desk as the door shut, shivering in the warm air of the office, at memories better left forgotten.

"A Euclid in the hands of a Keter... two Keter, rather. Either we're safe or we're doomed." Her rather demented nervous giggle was the only sound for several minutes, before she collected herself and sat up, breathing deeply. "What will be, will be." She reminded herself with a sigh, slipping her wallet out and flipping it open to a photo, tearing up a bit as she stared at it. She put it away with a sigh, reaching out to touch the button for the intercom.

"Pinkamena Diane Pie, Rarity Belle, Twilight Sparkle, Rainbow Dash, Fluttershy, Applejack, please come to my office once classes are finished."

Author's Note

(1) I'm not sorry.

For clarification, the coversation between Luna and the Mane 6 will not be in the next chapter- it's contents will be referred to if I ever get far enough off my lazy ass to get to near the end of this ride.

Instead, we move straight into Sunset getting fitted for new clothes... and fitted into other things, whether she likes it or not, in "Whoops! There Go My Pants!"

And I'll toss in some music appropriate for Pinkie:
