1 - Impromptu sex ed class
So Celestia was dead.
Naturally this was quite a shock to our hero Twilight Sparkle. That her mentor and idol had died peacefully, of natural causes, surrounded by friends and loved ones did not ease her mind. That may be the way everypony hopes to die one day, but Twilight was nevertheless inconsolable for several weeks.
Her friends were there for her of course, but eventually decided it was best to let her mourn in solitude. They say time heals all wounds, and all were sure Twilight knew that at a moment's notice—should she need them—they would offer her their support again.
They could not have known the thoughts that were spinning in the young mare's head as she lay there in her bed those long days, crying into her pillow. Eventually she had stopped crying, and started thinking. Twilight was after all a rather neurotic pony, even after all she had been through up to this point, she was still prone to overanalyzing and hyper-focusing if left to her own devices.
In particular she was thinking about her life going forward, and the moment her beloved sun goddess had passed. Naturally when an alicorn of such immense magical prowess left the world her magic had to go somewhere. Being the Princess of Friendship, and knowing the Friendship = Magic axiom, Twilight was quite sure that she was going to be that somewhere. She hated to even consider it, but deep down this may have been the primary reason she was so intent on unceasingly remaining by Celestia's side near the end.
She had been right of course. As Celestia slipped away, a small portion of her magic left the mortal realm, perhaps her soul itself on its way to the next life. But the majority of her innate energy smashed straight into Twilight. It was instantaneous, as if with a "crack!" from a bolt of lightning, indeed our hero felt as though she had been electrocuted through and through.
So she lay there in her room all alone and pondered what this meant for her. After much deliberation she came to the conclusion that her life from this point onwards was practically meaningless. She would never have to struggle for anything again. With the power the princess had left her, and her won mastery over the magical arts, she had almost complete control over her surrounding reality. Celestia leaving the scene had granted her a level of power almost on par with back when she defeated Tirek, but had also removed the only pony in Equestria who had the ability to reprimand her, or for that matter apprehend her. Barring any new players on the scene, there wasn't a single being she knew of that could stand up to her as she was now. She could do whatever she wanted...
It didn't take long for her to decide to use this power to satisfy her every sexual fantasy, starting with growing herself a rather (some would say exceedingly) large penis and a fat pair of balls. She'd often done this in the past, but only for the purpose of masturbation. Today though, she would have much loftier goals than bringing herself to climax. Not to mention, with her new boost in energy, the cock she had conjured was more biologically accurate (despite its absurd size, about 2 feet long and around 5 inches wide) and sensitive than any she had been able to grow in the past.
Definitely, She thought to herself.
A conjured penis of this quality deserves far better than a sad lonely hoofjob.
She got up out of bed, giddy with the ideas swimming in her head. A wave of pink light washed over her and she was suddenly presentable for the first time in weeks. She also made her new addition invisible until she would put it to use.
"Time to go out, I've been in this stuffy room for long enough."

"Twilight! What a lovely surprise, it's so nice to see you up and about!" Cheerilee beamed at her as Twilight walked through the door of the classroom.
"Hi Cheerilee, yeah I'm feeling much better," Twi smiled back.
"What brings you around here? I'm just in the middle of class right now but—"
Twilight's horn lit up with a startling flash, so bright all the students and their teacher had to shield their eyes.
Ok I'll start by casting Subtly Suggestible, Octafilly's hex of horniness and Hedgegrim's open-mindedness spell. She thought to herself. That should make everyone go along somewhat reasonably. I better also add some spells over the building so we're not interupted. And finally I'll add my own creations, Twilight's patented stretchy pony spell, and instantly clean privates, for my own quality of life.
All of this occured in a split second, with that bright but brief flash of magical light from the Princess's horn.
Time to have some fun. The Princess was shuddering with excitement at finally being able to use the spells she developed. She realized that deep down, she had always wanted to do something like this, and the moment had finally arrived.
"My goodness Twilight, I never knew you had such a... uh.." Cheerilee had spotted her massive member and couldn't hide her sudden arousal, even in front of her students. Nevertheless she tried to remain professional.
"Have you always been so... um... Perhaps you should wear a cloak or something, walking around like that really isn't appropriate, this is a school after all..."
Twilight looked the teacher in the eye intensely and smiled. Cheerilee's heart and pussy melted instantly before Twilight's powerful presence, while the students watched on with intrigue. Something pretty interesting was happening in class today, and they all felt that the mood had changed somehow. What was it they were feeling?
"Everyone gather round please," Twilight announced, in her most librarian-y tone of voice.
She grabbed a hold of the squirming purple pony in front of her and lifted her into the air with her magic. "Eep!" squeaked Cheerilee.
Twilight flipped her mare, lay her back on her own desk and spread her four legs, exposing her beautiful pony pussy, soaking wet for all to see. And all were seeing, the fillies and colts of the class were eagerly forming a circle around the alicorn and her adorably flustered prey.
"Today's lesson plan is being changed," she continued as her audience looked on in awe.
"Today we're learning about sex, with your special guest, your Goddess, Twilight Sparkle." The desk was lowered by magic to the perfect height as Twilight sauntered towards it. "Plonk, plonk... fwap!" All the young ponies were staring intently as she placed her front hooves on either side of their teacher, and laid her monstrous member atop the trembling mare. Cheerilee was astonished to see that it almost reached all the way to her neck, and was near as wide as one of her legs. The immense pussy-destroying rod was pulsing, she could feel her Goddess's heartbeat through the contact with her underside, and its flared head was already drooling precum onto her chest.
"Twilight p-please, this is quite in-inappropriate..." She stammered.
"Even if this class were somehow approved... I couldn't possibly take such a... s-such a huge penis."
"Is this what you're teaching these young ponies?" Twilight feigned shock.
"Now now Cheerilee, ponies should never give up on what they really want, you need to give it your all!" She continued.
"You do want my cock don't you?" Twillight began waving her hips side to side, causing her dick to slide left and right over Cheerilee's belly. The teacher's eyes followed the head back and forth, as the shaft rubbed her chest. She couldn't believe it, but she realized she knew the answer.
"Y-y-yes... I do want it." She admitted. She was blushing furiously under the gaze of her class. She imagined they would never respect her again, but she knew that right now she needed Twilight's love more than anything else in the world.
"Well in that case, let's cheer her on everypony!" Twilight addressed the students.
"This is called sex everypony! Ponies with penises, usually stallions, need to insert their nasty cocks into the naughty pussies of silly little mares like your teacher here!" She explained, as she slowly pulled back her hips, aligning her tip with Cheerilee's entrance.
"Sex feels great for everypony, which is why Miss Cheerilee is so excited right now. She can't wait to feel good having sex with me! Most stallions penises are much smaller than mine though, so she's not sure if she can do it. Let's all cheer her on while I try to put it in!"
The class, which had remained silent this whole time, slowly began erupting into cheers for their beloved teacher.
"You can do it Miss Cheerilee!"
"Come on teach, try your best!"
"We believe in you!"
"We love you Miss Cheerilee!"
Words can not describe the mixed feelings of embarrassment, apprehension, resounding love and overwhelming lust Cheerilee was feeling, lying there on her back, a Goddess's cock poking her pussy and all her students encouraging her. It was all just too much for the poor mare, and she began completely losing herself in the moment. Her face was completely red and she closed her eyes. Her breathing became heavy, and she tried to prepare herself for what would come next.
Twilight on the other hand, was hard at work beginning the next era of her life. Finally she would use this beautiful cock she'd created to invade the pussy of a gorgeous mare who couldn't hope to resist her. From now on she would live in ecstacy, only held back by the limits of her imagination. All it took was that first push...
She leant her hips forward at a snails pace, slowly increasing the pressure on Cheerilee's pristine pink slit. The mare below her felt the force increase and let out a moan, increasing in volume as her Goddess pushed harder. "aaaaoooOOOH!" Twilight knew she could fit in of course, she cast a spell over everypony here that made them stretchy to allow for her fantastical size, but Cheerilee didn't know that. Twilight had never used the spell in practice anyway, so the sensations were new to them both. Her cock stayed its course; she felt her head mashed against a squishy wet wall, seemingly impassable. Twilight grunted, increasing her force even more until suddenly she felt a small gap open up. The teacher's perfect pussy stretched impossibly wide, and all at once accepted the head of twilight's massive member with a slick "shlip". Twilight's helpless mare squealed, and their audience gasped.
"Ooooh my gosh you're amazing." Twilight moaned. The head of her cock was being stimulated all over, in a hole that felt immensely tight yet slippery.
"Ah..." Cheerilee was panting, her breath hot, "I can't believe it went in... that huge thing."
"Well don't give up yet," Twilight countered. "You've still got a long way to go, and I'm tired of waiting, I think it's time to get serious."
"Huh? W-w-wait, Twilight, please go slowly, i-i can't— Aaaahhhh!"
The alicorn ignored her, thinking only of her own pleasure as she ploughed forward into the stuttering ponies' cunt. She felt incredibly proud of her "patented stretchy pony spell", though that pride was not nearly as important to her as the other feelings she was currently experiencing. The pussy she was conquering was utterly perfect, just as she had dreamed. Her ludicrous size made Cheerilee's vagina so tight that every point on her cock was being stimulated, and yet she never felt as though she was being suffocated by the tightness. She could always just barely break new ground, shove in that next inch. She could also see that despite the prominent outline of pony dick that was travelling up Cheerilee's tummy, the pony below her was in no pain at all. In fact, she seemed just as lost in pleasure as Twilight herself. Yes, she thought, The spell was perfectly tuned, I really am a genius.
Cheerilee squealed and Twilight came to a stop. Her head was pressed firmly against the mare's little cervix, with only about a third of the shaft inside. Cheerilee locked eyes with her Goddess and the two shared a moment. Twilight could tell that her mare knew what was going to happen next, after all she was a smart pony. In that look they shared Cheerilee communicated that she had completely given herself over to the radiant alicorn inside of her. She no longer had any care to change the situation, and she knew that whatever happened, she would be safe in the arms of her Goddess. Perhaps it was because of this change in Cheerilee that her deepest barrier gave way far easier than her entrance had. All it took was the slightest bit of added pressure and our hero was accepted wholly into the mare's womb, stretching just as her pussy had, in order to accommodate her girth.
"Aaaaaaaah," the two both cooed, lost in the moment together. For a moment Twilight had a private laugh to herself. This really isn't a very accurate sex ed class. She cast the private joke aside and pressed onward.
In no time at all the rest of her shaft was buried inside Cheerilee, inch after inch swallowed up, piercing deeper in ways not at all anatomically possible under usual conditions. But that's the beauty of unlimited power. Twilight thought to herself, feeling a sense of wonderful completeness as their hips finally met. She was balls deep.
The fillies and colts of the class observed in amazement the sight before them. Two mares breathing heavily, one of them their teacher, with a huge bulging shape visible all along her body, only ending before it would be poking her chin. Twilight's balls ached. She was so excited, she knew she was going to bust the fattest load of her entire life inside this mare, and she wanted to make it count. She pulled back as far as she could, and then pummeled her way back into the pussy beneath her with all her strength. She pulled back again, and began to repeat the process, piston-ing in and out of Cheerilee with gusto.
The teacher herself was in complete shambles. Twilight's magic made her insides malleable, but that didn't stop her from feeling every part of her make way, again and again, for the colossal intruder. Twilight had turned her into—and was treating her like—nothing but a living sex toy to envelope her prick. Cheerilee was in love. She had begun to orgasm around Twilight's third thrust, and was now in a heavenly state of never-ending climax. Every pump renewed her bliss as the unstoppable princess continued fucking her silly.
Twilight's pleasure was mounting, Cheerilee's orgasms were making her hole contract and shiver, creating amazing sensations for the princess. On top of that, there was the joy she felt to be fucking a mare, finally fucking someone properly. Honestly it was a wonder she hadn't nut as soon as their sexes made contact; she had been hornier when walking into this class than she had been any other day of her life. She was completely at peace with the world as she felt her cock getting stiffer and a large pressure building.
Cheerilee felt it too, and it was the toy's only warning before her Goddess slammed straight to the back of her pussy, falling on the desk and laying her full weight on top of her. Twilight clutched her mare tightly, her head laying over Cheerilee's shoulder with her cheek touching her neck as she began to cum. With every blast of semen that erupted into the helpless pony, Twilight squeezed her tight, pressing their hips together even closer, only relaxing for a moment before the next wave. Cheerilee had thought there was no room left inside of her, but she saw now how wrong she was, she could feel every spurt of her Goddess's essence deposited in her battered womb, and none was leaking. She remained there, blissful in Twilight's strong embrace as the alicorn spasmed over and over again, for almost half a minute.
Finally, Twilight was finished. Her boner began to subside, but she wasn't tired, in fact she still felt completely energized. Enjoying the moment for a little longer, she brought her face up to Cheerilee's and gave her a deep sloppy kiss. The mare was putty beneath her, completely exhausted by the most intense sexual experience of her life, but she tried to reciprocate her Goddess's kiss with the last of her energy. She could feel the penis inside of her shrinking, ready to unleash the reservoir of semen that it had created within.
Twilight climbed off of the desk, removing her cock from the pussy it had terrorized. She noted with pride that Cheerilee's slit was still exactly how she had found it, thanks to her spell it hadn't been enlarged, or received any kind of damage at all. Well... there was one difference, that being the steady flow of jizz that was exiting the mare's vagina, pooling on the floor beneath the desk. She could see that Cheerilee's stomach was still bulging outwards, even without her monster cock, and estimated that she had deposited around 5 liters of the stuff. The thought was making her hard again.
"Okay class!" She spoke to the incredulous onlookers around her, "That's it for the demonstration."
"Now who's ready for some hands on learning?"
