Back at the School of Friendship, Starlight Glimmer decided to get back to her regular job instead of tending to research in the Surveillance Room. Even though she was growing just as fascinated in their work as Twilight and Sunburst were (especially after discovering the potential those Alternate Universe spells had to offer), she knew that it wouldn’t have been right to leave her Guidance Counseling work unattended. Considering how many students came to Twilight’s school to learn from the best, the last thing Starlight wanted to do was make anyone feel left-out or lost in their studies. Not to mention, the mare felt a strong sense of pride when it came to helping out Equestria’s youth, and knowing her efforts would leave an impact on their futures.

Or at least, that’s how she wanted to feel as she sat in her plush office chair, and stared at the blank wall at the other side of the room. Unfortunately, since only a few students were at the School of Friendship that day, it seemed that Starlight had just clocked in for a very long and uneventful shift. “Uggghhhhhh…” Less than an hour into her “work,” and with nopony coming into her office since she did, Starlight slumped forward to face-plant her desk. “... Darnit,” she muttered under her breath. “I should’ve stayed at the castle…”

Starlight knew that given the circumstances, she should’ve felt a little grateful for having such a lax job at times like these. Considering how arduously the other Elements worked in their full-time careers between teaching classes, Starlight legitimately couldn’t understand how those six were able to maintain their friendships with such cramped work schedules. Heck, if she hadn’t grown to know the Mane Six so personally over the past year, she likely would’ve assumed that they needed a mountain of cocaine to keep themselves awake 24/7 in order to get everything done on time. And while it was nice having an office to herself a lot of the time without much interruption, it wasn’t hard for Starlight to feel guilty sometimes; honestly, the mare considered setting up a cot in her unused closet, just so her friends could have a place to take a nap between classes if they needed it.

But for now, all that Starlight had was free time while sat in her chair in wait, even though she was sure that nobody was going to come and visit her today. On most other days, she likely would’ve found some solace in that fact, and maybe use it to her advantage. But since she knew that she could’ve been using this time to help Twilight and Sunburst with their surveillance research, the mare sighed in disappointment while pulling her head back to gaze at the ceiling. Even though she already knew through multiple bouts of boredom that there were fifty-six tiles on her ceiling, she still counted them out to herself as she tried to think of something to do.

I should’ve at least brought something to read, she thought while counting the tiles blankly, already having reached the twenties without any issue. Ugh… Where the heck did that journal of mine go?! I swear, if Sunburst took it, I’m gonna strangle him with his own goatee! Okay, stop it, stop it… You know he wouldn’t do such a thing. He might be a perv, but he’s not a thief. If anything, Spike might be more likely to take it. Although I’m pretty sure if he did, I’d already know by now. Goddess… I really hope Twilight didn’t find that thing. She’d probably throw me in Tartarus next to Cozy Glow if she discovered that...

As she thought to herself, Starlight shuddered at the idea of her friend/Mentor discovering that stupid journal full of her depraved writings. While she knew she couldn’t blame herself for writing that smut while in such a demented mindset (not to mention the immense boredom she experienced by living in a desert community with brainwashed ponies), she was doubtful Twilight would be as understanding of those excuses. Heck, considering how close she had gotten to Twilight and her brother, Starlight felt absolutely horrible for the things she wrote about Shining Armor.

And even worse, Starlight felt awful that she was missing that journal already.

After Discord had his fun and confiscated her book, Starlight spent half an hour tearing apart her room to try and find it. She had first assumed that Sunburst took it, but she believed him when he said he didn’t know where it went. And since she was too worried to ask Spike for assistance, the mare had to just hope it was stuck somewhere hidden in her room where nopony could stumble across it. Even if she couldn’t read it, she hoped that nopony else could either.

Back within the chaotic dimension he called home, Discord had Starlight Glimmer’s journal resting atop the end-table beside his reading chair. Even though he was currently busy with Twilight in the Surveillance Room back in Equestria, it seemed that he had been reading a good portion of the mare’s writings in his spare time. Despite a few grammatical errors here and there, the draconequus had to admit that she had quite a knack for erotic storytelling. And while he wasn’t cruel enough to send her journal around for others to find (at least, he wasn’t that cruel anymore), it seemed only fair to leave it out of Starlight’s hooves in case it brought up any villain-esque tendencies within her.

But alas, while toasters fluttered around the living room with butterfly wings, and the sounds of clucking grass echoed from his floating lawn outside, Starlight’s journal was left wide-open with a small paper bookmark gifted by Fluttershy. And at the top of her aged pages, it seemed that Discord was just about to indulge in Part Three of her perverted writings involving a cuckolded Shining Armor:

“Aaaahhhhhh… It’s soooooo nice being King again~”

As the treacherous King Sombra sat back upon his Crystal Throne in victory, it was obvious from the actions of his two inducted subjects how easily he was able to overthrow the Crystal Empire once more. Princess Cadance, who used to be a beacon of hope for the resurrected city, was now moaning out in pure rapture while seated atop Sombra’s lap, and nestling herself around the thick girth of his cock. And as for her husband -- or more specifically, her former husband -- Shining Armor’s face carried a heavy coat of red from how hard he was blushing. Part of that blush was from the arousal he felt as he looked up from the bottom of Sombra’s throne, and got a prime view of Cadance’s glistening marehood as it was stretched tightly around the King’s shaft; the other reason for Shining’s blush was due to the pain he was feeling from the leash tightly bound to Sombra’s hoof, as well as the tight bindings that were still clamped around the base of his suffocated balls.

Shining had lost all track of time at that point, and was becoming entrapped in a heavy fog of shameful lust due to his defeat. Even the plastic band around his balls, which were still in place by Sombra to leave the former Prince his personal Gelding, were now only throbbing the slightest bit as they succumbed to a dangerously numb state. Luckily for the defeated stallion, the grip Sombra had on his leash made it hard for him to pay too much notice to how swollen and purplish his balls were getting. Not to mention, due to the shamefully hot sight he had of his former spouse getting penetrated by their new ruler, Shining was able to pay more focus to the plump, heavy orbs that were hanging freely between Sombra’s legs.

“Nnnnghhh!!~” Sombra groaned through his gritted fangs as he grasped Cadance’s hips tightly with both hooves, and repeatedly pushed her down his shaft like her pussy was his personal fleshlight. Her heated moans of pleasure sounded just as intense as any of the sessions she previously had with her husband; in fact, from the pained wince that could be seen on Shining’s face, it could be debated that he felt her moans for Sombra were more genuine. The mare looked absolutely elated while she hopped up and down her King’s Royal scepter, allowing him to fully claim her like he already had her womb. Shining had no idea if Sombra’s first rutting inside of his spouse impregnated her, but he knew that the Tyrant wouldn’t stop until it was confirmed. And considering how severely his own situation was looming towards such a dire fate, it wasn’t like he could do anything himself anyway.

Instead, Shining could only stare up at the two as they continued to fuck just inches from his face, which caused him to moan softly between his strained breaths. His snout was pulled in so close to the contact point between Sombra’s cock and Cadance’s cunny, that the intoxicating scent of both of their bodies growing hotter and wetter was practically flooding his lungs. Shining’s eyes were half lidded in a sickly mixture of arousal and discontentment, but it seemed that the latter feeling was bound to fade away soon enough. At least, that was how it seemed by the way his untouched cock was standing fully rigid, and throbbing hard enough to elicit muted bouts of pain up and down his writhing legs.

While the former Prince remained pinned underneath the two, his ears flickered as he heard Sombra’s growling voice addressing him between Cadance’s lustful moans. “Mnnnghhh… It’s truly a shame that you… Nnnffff~... That you gave up such a prime whore for your King~” he said with a tauntingly bitter hiss, which was accompanied with a shit-eating grin pointed down at the bound and cuckolded stallion. Even as Cadance continued to ride that superior stallionhood so vigorously between her moans, Sombra added down to the soon-to-be-gelding, “And to think, if I had never shown up to reclaim my throne, I… Oh yeah, right there… I-I wouldn’t have been able to keep such a worthless cretin like you from wasting your seed inside of her~”

Shining cringed as he groaned to himself, but he couldn’t bear to look away from the titillating view he had of Cadance’s cunt being used for their fiendish leader. The cuckold had no idea how he looked behind his heavy blush, but his awestruck expression seemed to please Sombra enough to laugh maniacally in his throne. As for Cadance, who was bearing herself down even harder on Sombra’s girthy cock, rivulets of her arousal were finally trickling from the tight confines of her pussy to drip on top of her former husband’s head. Shining moaned a little louder as he felt those warm trickles against hit his fur, and he was able to catch the slightest scent of her syrupy sweet nectar. But alas, due to the state of his increasingly swelling balls, not even the smallest droplets of precum were able to spurt from his throbbing member.

“Hmmmmm…” Sombra grew an evilly demented grin as he looked back up at Shining’s former spouse, who seemed to be growing closer to her latest climax as she clenched harder around his cock. He lost count of how many times he managed to make the Princess orgasm in his own grasp as opposed to Shining’s, but he knew that it would be deliciously satisfying to lay some more salt into the defeated Prince’s wounds. So while Shining was left to gawk up at them without any chance of release, Sombra decided to ask the mare, “What do you say, ‘Princess’?~ Do you feel that Shining’s seed is worthy of your womb anymore?~”

“AAAHHHH!!~” Cadance's head reeled back while she moaned out in carnal bliss, and her smile looked disturbingly genuine as she shouted enthusiastically, “N… No it’s not, my King!~ I… I only want YOURS! Aaaaahhhhhh!!~”

Shining expected his heart to snap in two from hearing that amorously cruel statement from his wife, but by that point, it was clear that any emotional turmoil he may have felt was thoroughly numb. So instead, the stallion just moaned softly to himself in shameful lust as he writhed beneath his King, and tried his hardest to savor the last bouts of arousal he was likely to feel from now on. Unfortunately, due to how tightly Sombra’s leash was pulling the cuck’s head in towards his crotch, it wasn’t long before his senses were overwhelmed with the thick, heady aroma of his Master’s musk.

The scent of unwashed sweat and testosterone-laden flesh was absolutely nothing like the tantalizing brand Shining could’ve recognized from Cadance’s drooling marehood. But at the same time, the Ex-Prince still groaned with a strong shiver the moment he took a deep breath of Sombra’s plump, heavy balls as his face was pressed up against them. His nostrils flared while his snout became buried between those hefty orbs, and were nearly blocked by the loose and wrinkly skin that draped over his muzzle. And even as he sensed how close Cadance’s body was pistoning on Sombra’s cock above his head, Shining’s eyes rolled back from the sickly musk he was forced to suck in and enjoy for his King’s pleasure.

“Mmmmm… That’s it, Gelding~” growled Sombra with a menacing grin, making sure to emphasize that term like it was Shining’s new title from now on. “You better get your lips around your King’s balls. Because by the time I’m through…”

Shining’s head was perched at the edge of Sombra’s throne as he meekly glanced up at him, and caught sight of that evil grin that was lined with razor-sharp fangs. Meanwhile, Sombra narrowed his piercing red eyes as he completed his statement ominously. “... My balls will be the only ones you’ll ever feel pleasure from~”

Due to how badly his own balls were pulsating in numbed agony while tightly bound and turning a darker shade of purple, Shining knew that his King’s statement was likely to be true soon enough. And since Cadance had already succumbed to the Tyrant’s twisted whims a long time ago, Shining knew there was no use to keep resisting. Instead, Shining closed his eyes as he took one final breath, and shuddered while parting open his lips. The thin, wrinkly flesh from Sombra’s sac quickly slipped into the former Prince’s muzzle, and the strong salty taste was intense enough to make Shining’s brows furrow briefly. But alas, as more droplets of Cadance’s arousal dribbled down over Shining’s face and mane, the unicorn let out a muffled whimper before he opened his mouth a little more, and felt one of those heavy balls start to slip into his muzzle.

“Mnnnghhhhh!!~” Sombra may have not been one to seek stallions instead of mares, but it wasn’t like Shining was going to be much of a stallion soon enough. Not to mention, the fact that the leader he defeated was now sucking his balls was almost as pleasurable as Cadance’s tight walls trying to milk his cock. Fortunately for the Tyrant’s sake, Shining was too broken to even think of biting down on either of those virile orbs he was worshipping. Since he knew that Sombra’s claim was correct, it wasn’t long before Shining moaned out through his King’s endowed balls, and even brought out his tongue to drag along the underside of that loose sac.

“Ooooh!!~” Sombra jolted with an elated shiver, but was able to keep his composure well enough to maintain his tight grip around the moaning mare who was just about to reach her climax. And since Shining’s mouth was being put to proper use around his King’s patronage, Sombra started to moan out in anticipation of his own orgasm as well. “Mnnnghh~ You… Y-You better suck on your King’s balls properly, Gelding!” he said through his lustrous groans as both he and his Princess felt themselves reaching closer to their peaks. “I… I want you to feel those balls as they deliver what you never will!!~”

Shining’s eyes clenched shut in trepidation, but he did as he was told while opening his muzzle even wider. Despite how thick and heavy each of those plump balls of Sombra’s were, the cuckold was somehow able to stuff both of them into his mouth without them getting too close to his teeth. He could hear his King’s long and satisfied hiss from up above, as well as heavy groan over the sounds of their bodies smacking against one another. Shining could also hear the hefty cries from his spouse, who was too deeply enamored in Sombra’s dominant embrace to even care what her husband was doing anymore. Shining’s defeat had already settled in, and he knew that his sterility would likely follow suit soon enough. And as his mane and coat became increasingly coated in his Ex’s sticky secretions, and his sinuses were flooded with the heady musk of his King with each breath he took through his nostrils, Shining felt his very soul succumbing to the fate he had been given while his tongue burned with Sombra’s sweat.

“Nnnnnn…~” Shining shuddered to himself as he wrapped his lips tighter around the base of his King’s balls, which were tightly confined inside of his overstuffed muzzle to ensure he could only taste Sombra first and foremost. Even the titillating scent of Cadance’s sex wasn’t able to reach his snout while it was pressed up against the base of Sombra’s cock. The Princess’ dripping cunt repeatedly pressed against the top of Shining’s head, and made him feel more like a distraction than anything they may have had before. And just as he felt his cock throbbing immensely hard to send bolts of pain through his tied-up balls, the cuckold braced himself as he heard the two reaching their shared moment of lustrous release.

“AAAAHHHH!!~”

“AAAIEEEEEE!!~”

“CADANCE!!~”

“S-SOMBRA!!!~”

Shining felt the weight of his wife’s body press down hard atop his head, and it took everything he had to keep his muzzle wide-open as it held his King’s lineage. The couple’s primal cries bellowed out loudly enough to leave a ringing in Shining’s ears, but he couldn’t do anything to sate that painful stinging while feeling Sombra’s balls churning strongly inside of his mouth. The heavy pulsations that came from those orbs made Shining’s lips quiver tightly around them, and he could feel every spurt of his King’s seed as Sombra held his new wife in close. Meanwhile, Cadance was crying out in pure rapture as she held the King in her embrace so passionately, and felt every rope of his cum flooding her insides to fill her womb once more.

“Mmmmmmphhh!!~” Cadance wrapped her hooves around the back of Sombra’s head, and gave him a deep and passionate kiss that rivaled the one she gave to Shining at their wedding. Of course, the King wasn’t one to turn down such a thoughtful gesture, and he held the Princess in tightly so his tongue could slather the inside of her muzzle. Cadance did the same with her own tongue, and paid no heed to her former spouse as the two shared such a sloppily tongue-laden kiss. Meanwhile beneath the couple enjoying their makeout session, the poor cuckold was left to continue suckling on Sombra’s churning balls, and feeling the last remnants of the King’s seed as they made their way inside of the mare Shining no longer had.

And even as the new Royal Couple remained in that tightly sensual embrace, savoring each other’s warmth while kissing and locked together, neither of them paid any notice to the lone cuckold who was pinned underneath them. Instead, Sombra held onto his new mare with a devilish grin, and was already thinking of new terrible things to implement on poor Shining next~

Discord had no idea whether or not Starlight Glimmer still had kinks that extreme in her repertoire of erotica, even though it was obvious she was re-reading her stuff shortly after finding it again. But despite how entertaining it was to tease the poor mare with his unique form of Kink-Shaming, Discord was on the fence regarding whether or not to return that journal back to her. For the time being, the draconequus was intent on at least finishing his read-through of the booklet before making a decision, mostly so he can determine what to do after being well-informed on the matter. And hopefully, Starlight won’t make the connection that it was him that took it from her bedroom.

Of course, even if she did try to confront him on the matter, Discord had a pre-addressed and stamped envelope at the ready next to her journal. While he was certain the mare wouldn’t provoke him for his uninvited readings of her work, he wasn’t afraid to dish back any payback if she was unfortunate enough to do so. But for the time being, Discord was optimistic that his envelope wouldn’t reach the Crystal Empire anytime soon, if at all. Of course, that positive mindset was more for the sake of Starlight (and probably Shining Armor too) instead of himself.

Back at the School of Friendship, Starlight Glimmer’s office was no longer as silent as it had been before. Since she had nothing else to do, the mare decided to borrow one of the spare typewriters from the school’s storage room, as well as a stack of paper. While she wasn’t too worried about using school property, since she left the proper paperwork in the inventory to prove it wasn’t stolen, Starlight really hoped that Twilight wouldn’t ask her what the typewriter was for. Or at least, she hoped the Princess wouldn’t be too curious about what she may have been writing.

“Okay… let’s see how this works…” Starlight hadn’t used a typewriter in years, since her magic was more than enough to write down her fantasy fiction on paper. But given what happened with Sunburst, the last thing Starlight needed was for anypony else to track down her stuff through her aura signatures. And given how often she and other girls have been using typewriters for their dissertations and study plans, she was hopeful the monotone font would give her a little more anonymity to craft out her storytelling abilities in private.

Fortunately for Starlight, it didn’t take her long to get the typewriter synced properly with the page, and for her to start typing out something new. The loud clacking noises of her machine echoed within the room, and soon sounded like music to her ears while she used her free time to her advantage. Since she was left alone to her own devices, Starlight was smirking with a small blush as she began her newest creation:

“Princess, I… I don’t know if this is alright,” muttered the Guard meekly, his blush growing heavier while he stood at attention before his Superior. Even though he was within the confines of her bedroom, it was hard for him to remain in focus while she was sprawled out so enticingly. However, the sight of his Princess was much less awkward than the Prince seated behind them, who was bound to his chair with a thick bundle of rope to ensure he couldn’t break free.

“I already told you, Private,” purred the Princess while her lustrous grin remained as wide as ever. She licked her lips while gazing at him sultrily, and said with greater insistence, “He’s fully consenting to this, and you won’t get in any trouble for following your orders~”

Starlight giggled to herself as she kept typing studiously, already feeling her creative juices flowing like she had back in her villainous days. “Oh man,” she muttered to herself with a bitten lip. “I really hope I can keep this story more vanilla than my older stuff…”
