Ever since the Crystal Empire’s sudden re-emergence into Equestria, and its subsequent rescue by its new leaders, the revitalized city had become quite the popular spot for travelers and historians alike. The Crystal Castle, which was once a towering monument to its morbid past and the Tyrant who oversaw it, was now a shimmering beacon of hope and inspiration upon the Empire. On a regular day, thousands of ponies were expected to tour the castle grounds to appreciate its unique architecture and beautiful scenery. Of course, that wasn’t counting the hundreds of castle staff and guards who also roamed the halls at all hours.

Because of all that, the idea that any space of the castle could be empty or silent was fairly difficult to consider. But for two stallions who were walking side-by-side down one of the upper-floor hallways, the only sounds that could be heard were their hoofsteps and the occasional clanging of their armor. One of the ponies was Flash Sentry, one of the Crystal Empire’s top guards and entourage for the Royal Leaders. And walking beside him with an equally content smile was Shining Armor, the Prince Consort of Equestria and husband to Princess Cadance.

Despite their high rankings and levels of importance, the two ponies seemed to be completely alone as they patrolled the vacant hall of the Crystal Castle. Due to their seclusion, the Prince felt rather comfortable to ask the tan pegasus, “So, I take it you ensured this wing of the castle was off-limits until three this afternoon?”

“Absolutely,” replied Flash with a nod to the white unicorn. “The staff have been informed and re-scheduled as you requested, and magic barriers have been placed along all the entrances with guards posted.”

“That’s good to hear, Private,” noted Shining as he gave the soldier a courteous smile. But despite hearing that confirmation from Flash regarding the barriers, the stallion’s horn was still lit with the faintest hue of his pink aura. Fortunately, his guard didn’t say anything about it as they walked together. Much like Shining’s occasionally random mood-swings, or the way he wore his armor a little more loosely than before, Flash had grown accustomed to those changes since they began appearing several months ago.

However, even with those recent developments, the pegasus was still a little confused about the Prince’s recent need for seclusion over the past few weeks. While he could understand the need for privacy in regards to somepony in Royalty, he tried his hardest not to skew his muzzle in thought. Although in retrospect, Flash could safely say that in comparison to other recent events in the Crystal Empire, Shining needing a little time off every week or so wasn’t too odd. At least not compared to other elephants parading around the rooms of the Crystal Castle.

But alas, Flash Sentry took a quick breath before deciding to bite the bullet. “S-So, ummm… Shining, would it be okay to speak freely?”

The Prince merely huffed with a carefree smile as he nodded casually. “Well, we’re in the perfect place for it. So feel free to speak, Private.”

Flash seemed happy his superior was in such high spirits for the moment, and he smiled back while exhaling sharply. “Okay, ummm… I-If you don’t mind me asking, is… Is this in any related to, uhhh… to… ‘You Know Who’?”

Shining paused for a moment and stood in the middle of the hall, which Flash copied while a worried expression grew across his face. The Prince seemed a little surprised that his Private would ask such a thing, but he was able to sigh and keep a coy smile on him while answering. “Flash, you don’t have to refer to Sombra like that. He isn’t a curse word, you know.”

Despite feeling like he should’ve chuckled to that response, Flash couldn’t help shrugging uncomfortably, “Wellll… some of the Crystal Ponies still see him as so, to be honest.”

Shining’s smile dropped as he exhaled with his lips pursed annoyedly. However, the unicorn still rolled his eyes with a brief hum before he said, “Hmmmm… I suppose that can’t really be helped, can it? But still, I really hope you of all ponies don’t think he’s still evil, right?”

Flash huffed through his nostrils as he kept his muzzle uncomfortably shut. Given how close he had been keeping track of events within the castle, he knew that Shining Armor was expecting him to agree. Heck, technically speaking, Flash Sentry had been around that former villain for the longest time since he was the one to discover him in the Frozen North by himself. However, the pegasus couldn’t help tilting his head before answering in a meek and honest tone, “Well, I… I don’t think Sombra is gonna take over the Crystal Empire again, if that’s what you mean.”

Shining Armor sighed with a roll of his eyes in disappointment, no matter how much Flash tried to force a nervous smile on his face. However, the Prince knew that a lot of ponies were still uneasy about someone like Sombra still being alive, let alone living in the very castle he once ran with an Iron Hoof. But much like countless enemies before, the Royal Sisters and the Elements of Harmony were determined to try and reform the former King Sombra after he was found preserved in ice with his horn missing. But even after a year of reformation, and a tremendous amount of progress seen by the ex-Tyrant in regards to his behavior and respect for the Empire’s new leaders, a large majority of ponies still saw him as a ticking time-bomb waiting to overthrow Equestria once more.

Nevertheless, Shining still felt a little peeved as he said to his Private, “Flash, you know that Sombra is trying to be a better stallion.”

“I do, I really do!” blurted Flash insistently while holding out his hoof. “Believe me, I don’t doubt that for a second. It’s just…”

During his pause, Flash Sentry bit his lip as he looked away from Shining’s direction briefly. The last thing he wanted to do was make any uncomfortable statements or assumptions, but he felt like something had to be said to the Prince himself. “Well, ummm… Just so you know, your Highness, I… I think a lot of the castle staff is growing worried about your, ummm… your friendship with him.”

Shining’s eyes widened in surprise, with the slightest flash of worry stemming out for the split-second Flash wasn’t looking at him. The unicorn looked away from Flash as his cheeks grew a tiny hue of pink, and he breathed out shakily through his nostrils before asking, “Wh… What do you mean by that, Private?”

“You know what I mean!” blurted the pegasus with a sharp huff as he turned back to face Shining. While he was afraid of what he could get away with saying to Royalty, he was too worried about the Prince’s reputation to leave his comments unsaid. “I mean… I totally get it, alright? Your sister is friends with almost every villain she fought, and that’s fine! A-And the fact that you’re trying to do the same with Sombra is… it’s really admirable, I swear! And I’m not just saying that because you’re my friend, okay?”

Shining kept his muzzle tightly shut, but he still nodded thankfully to hearing Flash say that last part with a sincere tone.

“But… But you have to see how this looks to the Crystal Ponies, right?! Like… I know the past should be in the past, but they were still enslaved by him! And… and for them, seeing that the guy who saved them from that life is now friends with someone like Sombra is pretty damn controversial! And I’m sorry for swearing at you, Shining! I just… I don’t want you to get hurt by this...”

Shining may have not been offended by his soldier’s honest words, but he still kept a stern expression on his face while staring back at him. “Flash,” he began after breathing out softly. “I know that my rel--Friendship with Sombra is a bit… unorthodox, but I don’t think it should be seen as a bad thing. Heck, if all friendships were to be disspelled by outside judgement, then we’d probably never have Spike staying friends with King Thorax; and with that, we’d never have such a strong alliance with the Changeling Kingdom like we do today.”

Flash’s muzzle wrinkled a little as he avoided looking back at his Prince’s insistent stare. Even though he wanted to retort, he couldn’t deny that Shining brought up a valid point. “W-Well, ummm… I suppose not…”

“Not to mention, there are other rehabilitated foes who have committed just as many atrocities, if not more than Sombra had,” continued the Prince as he leaned in with a firmer stare on Flash Sentry. When the pegasus finally looked back at him, the Prince concluded his point with, “and if beings like Discord or Tempest Shadow can show retribution, then I don’t see how Sombra can’t do it as well. Besides, if doing something as small as playing chess or discussing history is enough to keep him from trying to reclaim the Crystal Empire, then I think that’s a sacrifice worth making.”

Flash Sentry just exhaled with a defeated pout, knowing that nothing he could say would be able to counteract Shining’s statements. After a couple seconds of awkward silence, the pegasus shrugged and admitted, “Well… Alright, I think I get why you--Wait, you discuss history with him?”

As Flash stared confusedly at the Prince, Shining just shrugged and asked, “What? I mean, he has been frozen for over a thousand years. Don’t you think there are things worth bringing him up to speed on?”

Flash had his muzzle open for a moment as he tried to fathom what to ask first. Considering how there were multiple historians living in the Crystal Empire in order to bring the Crystal Ponies closer to modern society, it was odd to think Shining would be giving Sombra any history lessons. Not to mention, Flash himself had a Bachelors degree in history from Cloudsdale University, which was why he was one of the first soldiers assigned to the Crystal Empire shortly after it was claimed by Shining and Cadance. But after everything else Shining told him, the soldier wasn’t too keen on saying anything else which could be misinterpreted poorly by the Prince. So after a pregnant bout of silence, Flash just closed his eyes and breathed out before he said, “Okay, ummm… you know what, that’s fine. If you want to be friends with him, I won’t judge. And… And I’m sorry for upsetting you.”

Upon hearing that, Shining said assuredly with a roll of his eyes, “Hey, it’s perfectly fine, Private. I know how poorly this might be seen by the Crystal Ponies, so you don’t have to apologize. I just want you to understand why I’m friends with him, and why wanting a little seclusion with him should be necessary.” After another moment, the Prince added with a more playful scoff, “I mean, I’d probably be on all the tabloids if any ponies got too close and saw the two of us alone, right?”

Flash could see from the Prince’s cheeky expression that he was not only right, but rather accurate about having that kind of worry. Flash didn’t need any further prompting to understand why, and shrugged as he replied, “Well, you got me there, your Highness. And don’t worry, I promise I won’t let any ponies interfere. And that includes myself, alright?”

“I wouldn’t expect anything less from my top soldier~” With a newfound smile spread warmly across his muzzle, he gave Flash a kindly hoof-bump in confirmation of his assurance. “As soon as you exit the wing, you can take your leave for the day, okay? I think you earned that.”

That response made the pegasus’ face light up rather happily, and he gave a grateful smile while nodding back to the Prince. “Oh! Ummm… Th-Thank you, Sir!”

“Not a problem,” replied Shining before he gave his soldier a proper Equestrian salute. As soon as Flash saluted him back, he waited for Shining to put his hoof down before trotting off to finish the patrol. Meanwhile, the Prince stood in place as he watched the pegasus leave, keeping his eyes narrowed studiously while his horn remained faintly lit. As soon as the soldier was out of view, and he looked around to ensure no other ponies were in the hallway, the unicorn sighed in sweet relief with his eyes closed.

“Oh, thank Celestia~” he moaned out weakly to himself, almost falling to his knees the instant he stopped using his magic after so long. The very instant his pink aura dissipated from his horn, he let out a shaky sigh while his torso changed appearance. Instead of the thin, slender physique he carried which made his armor look loose and oversized, a wave of magic revealed that it was actually quite snug against his more robust form. If Twilight was present to see it, she would’ve immediately recognized her brother’s magic as a simple camouflage spell. However, it was unlikely that even a Princess as smart as her would’ve have realized why he had a spell like that to cover his much rounder barrel.

As the Prince began to trot off towards the more secluded region of the guarded-off wing, he used a small amount of his magic to undo the armor he had been wearing since that morning. The polished metal fell onto the floor with a loud clang, which Shining didn’t mind since no ponies were around to hear it. He then paused his movements to undo the metal guards on his hooves as well, leaving him as unclothed as he usually did. However, with all of that armor off of him, it was much clearer what that camouflage spell was really for. His belly may have been obscenely larger and more rotund, but the rest of his physique was as fit as the day he and Sombra first met.

“Mmmmmmm…~” With no castle staff or guards around to see him in his true form, Shining Armor grew a relieved smile as he looked down at his swollen stomach with a half-lidded gaze. He had to lean himself against the wall as he rubbed his belly with a hoof, feeling just how tight and constricted his torso had gotten over the past few months. Stallion or not, the dreamful look in his expression was unmistakable as he petted his hefty bump and whispered sweetly: “Shhhhhh… It’s alright, little guy~ Nopony knows about you just yet…”

As he stared lovingly at the fruitful bump he was carrying in secret, Shining chuckled as he thought back to just how drastically everything had changed since he “befriended” the former King Sombra. Sure, the two became friends at first, despite opposition from everypony in the castle (including his own wife). But as the weeks passed, and his time with Cadance decreased significantly, it wasn’t long before he started spending more time with Sombra than he did with his loving spouse. He wasn’t sure when that friendship turned into something more… personal, but he was grateful that all of their meetings were kept behind closed doors. But even now, with the biological proof of his affair with a former enemy showing as clear as day, Shining couldn’t say he felt the slightest twinge of regret as he felt the warmth and comfort of his pregnant belly.

By the time he was able to continue walking normally, the Prince carried a content smile as he walked away from his armor strewn across the floor. With all of the security measures in check, Shining felt much more comfortable about not having to keep his horn lit near-constantly. He wasn’t sure if using too much magic would be bad for the foal, but he didn’t want to take any chances and risk needing a medical professional just yet. While he knew he’d need to see a doctor soon, he tried to appreciate the temporary serenity of keeping his baby bump a secret. Plus, the added taboo of keeping such a shocking secret hidden from everypony (including his own wife) sent a tingle of invigoration through his spine that made him shudder.

Due to his facade being temporarily stripped-away, the stallion was able to waddle more comfortably to ease his aching joints. With a smile on his face, Shining reached the door at the very end of the hallway and knocked three times. After a brief moment of silence, the door was opened to reveal the father of Shining’s illegitimate foal. The former Tyrant known as Sombra may have had the same charcoal coat and pitch-black mane from when he was in rule, but his piercing red eyes no longer carried that ominous green hue or purple smoke from any dark magic. Instead, the only remnants of the ex-King’s horrid past were the curved cone of red-plastic that served as a prosthetic for his broken horn, and the noticeable fangs that peeked out from beneath his smirking lips. At seeing the nervously giddy-looking stallion at his doorway, Sombra chuckled lowly and asked with a velvety, deep-sounding purr, “Why hello, my little Prince…”

Shining Armor shuddered with an antsy grin at hearing that familiarly lustful tone. Even though most of the Crystal Empire cringed at the very thought of that voice, the pregnant Prince saw it as one of the former King’s most alluring features. Thinking back to when he and Sombra first became a physical item, he was absolutely certain that it was a big factor in complying to so many of the stallion’s needs and desires. After he breathed out shakily, Shining had to keep himself still while replying meekly, “H-Hey there, Sombra… I… I just got this wing cleared out, s-so...”

“Oh, that’s wonderful to hear, my little stallion~” Sombra growled as he narrowed his eyes with a more menacing grin. He then motioned his head back while keeping his hungry gaze on the Prince. “Well?~ Are you going to stand out there all day, or are you going to come in?”

“Oh! R-Right…” Shining and Sombra may have been a secret item for over half a year, but the stallion still giggled nervously like a schoolgirl as he waddled into his baby-Daddy’s living quarters. Despite the ex-Tyrant’s reputation and history regarding the castle, his apartment-like living space was surprisingly spacious and well-designed. It may have been a simple one-bedroom abode with a small kitchenette and other amenities, but Sombra couldn’t necessarily complain when the alternative was either a stone dungeon or a trip to the gallows. Of course, as soon as Sombra locked the door for the sake of their privacy, he seemed especially happy with where he was when he glanced back at his fruitful mate.

Shining sat himself down on the sofa, and propped his hind-legs up on the coffee table as he sighed in sweet relief. The Prince smiled in sweet elation, and rubbed his pregnant belly softly with a hoof while his eyes were closed. Meanwhile, Sombra chuckled to himself silently as he trotted towards the couch and sat down beside him. Before Shining could even get a moment to shiver at the feel of his lover’s embrace, Sombra held the Prince in close while resting a hoof atop that fertile bump. “Mmmm… I have to say, it’s nothing short of a miracle that Cadance hasn’t caught on yet…”

Even though he sighed painfully at the reminder of his wife, Shining couldn’t help shrugging as he replied, “Well… I usually wake up before her anyway, so I’ve been able to wait until she’s asleep to turn off my camouflage spell. P-Plus, ummm…” After a brief pause, the unicorn sighed while his embarrassed blush deepened while beside his mate. “About a month ago, she… she and I started sleeping in separate beds…”

That added response made Sombra’s brows raise in surprise, and he had to take a moment to see that Shining wasn’t lying about that fact. “Really?” he asked with a tone that bordered between befuddlement and slight concern.

Shining nodded while his lips were pursed and wrinkled shut. “Y-Yeah. Ummm… She said it’s because I snore sometimes, b-but… but I guess I shouldn’t be too worried about whether or not that’s true, should I?”

Sombra could only shrug as he continued petting his lover’s belly, knowing he couldn’t say much in regards to Shining’s compromised marriage. “Yeah, that’s fair enough,” he replied in a more solemn tone than before. “I mean, as soon as she learns about this, a separate bed thing will probably be the least of your issues…”

Shining began to frown as he thought that all-too familiar fact over in his mind, even though he knew he didn’t need the stress while he was so close to the estimated due date. Given how controversial Sombra’s very presence in the Crystal Empire was, the Prince knew that the reveal of their foal together would likely be the scandal of the century. Even if he and Sombra managed to survive any hateful mobs (or a rightfully vengeful Princess of Love), he was doubtful either of them could come out of this controversy unscathed. But alas, as he looked down at that swollen belly he was carrying, the Prince still smiled while beside the stallion he cared so deeply about. “Well… it’s not like we can go back and undo this, so… I don’t think it’s worth dwelling over right now. As long as our foal remains safe, and I… and I get to stay with you…”

As Shining glanced up at his secret mate, he smiled when he saw the enamored expression Sombra gave back to him. The Prince took a second to sigh blissfully before finishing his content statement. “Then I… I don’t think it matters what other ponies might think. Just as long as I have you and our child by my side.”

Seeing the sincere and caring smile the unicorn possessed, Sombra let out an involuntary “Daww~” before he leaned in towards Shining’s muzzle. “Oh, come here, you big softie…”

Shining closed his eyes and hummed sweetly as he kissed Sombra on the lips with loving embrace. While he knew their romance would likely be shocking to any ponies who witnessed it, the stallion couldn’t deny just how real his love for Sombra truly felt. In a perfect world, Shining would’ve wanted nothing more than to be with both his wife and Sombra as his mates. Unfortunately, due to how distant he and Cadance have grown over the past few months, he had grown accustomed to the sad truth that he’ll likely only have Sombra after their foal was born; and that was only if he was lucky, and neither he or Sombra get killed by the Empire’s citizens before they could start a new life together.

After the two pulled away from their tender kiss, Sombra decided to ask with a raised brow, “So… if you and Cadance are now in separate beds, I’m to assume you two haven’t done much… personal stuff?~”

Shining let out a bashful sigh as he shook his head with a small blush. “N-No… We… We haven’t done anything for about… a month and a half, at least?”

“Oh my…” As his grin turned more mischievous, Sombra leaned in and began to nuzzle the Prince’s neck while letting out a low and spine-tingling growl. “If that’s the case, then perhaps it’s good you’re spending more time with a naughty stallion like me, hmm?”

The stallion wanted to feel guilty for nodding, mostly due to knowing how selfish it was to be seeking pleasure from somepony other than the Princess he was married to. Nevertheless, he still carried a faint smile while he answered truthfully, “Well, I… I suppose that’s true. I mean, given how close we are to the due date, it’s probably best to spend as much time as we can together~”

“I couldn’t agree more…” With that, the ex-Tyrant leaned back in to give a much deeper kiss to Shining’s waiting muzzle. The pregnant unicorn let out a muzzled moan as he savored the kiss from his mate, keeping his mouth open while it was interlocked with Sombra’s. Shining may have not been able to comfortably turn his body towards him, but he still held onto the back of Sombra’s head with a hoof as their kiss grew more intense. Before too long, both of them were locked in tight embrace while kissing with their tongues meshing together.

“Mmmmm… Ahhhhhh~”

Between the stallions’ faint moans and the wet schlicks of their tongues, one of Sombra’s hooves remained atop Shining’s belly to continuously rub that baby bump tenderly. After a long and loving moment of increasingly passionate embrace, Sombra pulled his muzzle back with a gasp. “OH!!”

Shining’s eyes were widened as well, having felt that distinct kick that happened inside of his belly as well. “O-Oh, wow!~” he said in surprised elation. He giggled a little to himself as he rubbed his belly with both hooves alongside his foal’s father. “I… I guess the little guy was excited to feel you again!”

Even though he was rightfully happy to feel such a healthy kick from the foal his Prince was carrying, Sombra chuckled with a cheeky stare on Shining as he replied, “Well, then… I’m willing to bet he gets that trait from you~”

Shining turned his head away bashfully as he grew a small blush across his cheeks. Meanwhile, Sombra’s chuckle turned more lustrous as he bent in to begin kissing the Prince’s exposed neck. The pregnant stallion squealed and squirmed a bit, but wasn’t able to pull away from his lover’s embrace while seated with such a heavy addition beneath his barrel. Because of that, Shining could only giggle as his cheeks turned redder from a mix of laughter and enticement. “Mmmnnghhhh… S-Sombra, come on! Hehehehe… I… I thought you wanted to have fun~”

“This is fun~” noted Sombra when he pulled his muzzle away briefly with a devilish grin. “It’s not often I get to have Royalty melting in my embrace~”

Even though he knew his mate was correct, Shining still groaned as he tried to respond defensively between Sombra’s kisses against his neck. “Oh, come on…  You… You’re acting like I’m weak or something…”

“Wellllll…” As he nuzzled the side of Shining’s neck to keep him squirming, Sombra reached down with a hoof to grope the Prince just beneath that pregnant belly. The white stallion closed his eyes with a moan, and his hooves curled-up at feeling Sombra’s familiar grasp around his growing stallionhood. Meanwhile, Sombra merely chuckled and finished his coy response to Shining’s statement. “I wouldn’t call you weak, but not many ‘strong-willed’ stallions would consider begging for their lover to teach them a fertility spell, now would they?~”

Due to the ex-King’s inappropriate rubbing against his shaft, as well as his own guilt from the truth of that comment, Shining couldn’t say much in defense as he tried not to moan through his trembling lips. Instead, all that he could do was keep his eyes closed, and shiver with each skilled stroke Sombra’s hoof made to get his cock growing even harder. Of course, it wasn’t hard to get the Prince’s member rigid when he was with somepony he adored so shamefully; not to mention, Shining hadn’t had much action outside of Sombra’s quarters, so he was already antsy to get what he could in their limited window of time.

“Mmmm… admit it, Shining~” cooed the former Tyrant with a spine-tingling growl as he stroked the ever-growing length of Shining’s beneath that hefty belly. Meanwhile, his other hoof continued to pet that swollen bump tenderly while maintaining his domineering presence. “You and Princess Cadance might be better leaders for the Crystal Empire than me, I’ll freely admit… But I’m still a much stronger-willed pony than you~”

Shining shuddered with his eyes tightly shut while enduring his lover’s taunting words. While he wanted to just enjoy Sombra’s tantalizing touch, he couldn’t ignore what the former King was making him think about. Of course, given how he usually preferred taking the submissive role in the bedroom when he was with Cadance, the fact that Sombra was able to capitalize on that in secret shouldn’t have been too surprising. Plus, he couldn’t deny that it didn’t take long to succumb into adultery with the former Tyrant while overseeing his rehabilitation; nor was the Prince’s composure too hard to break when it came to Sombra’s coaxing requests to incorporate more… taboo spells into their secret activities.

And with the very foal of Sombra’s he was carrying being the strongest proof of the dark stallion’s claim, Shining had no choice but to sigh in defeat. “I… I suppose so…”

Before Shining could hang his head in shame with that admission, Sombra nuzzled beneath the unicorn’s chin while stroking his member. “Oh, don’t you worry though, my fruitful Prince~ You’re still a loving mate who knows how to make me happy. And in the grand scheme of things, what you’re doing now is most likely better than leaving me be when I was much less tolerant of change, correct?~”

The Prince tried to huff with a coy-looking smile, but the ex-King’s efforts were proving it difficult for his mate to maintain focus. With each tentative stroke Sombra made up and down his shaft, Shining squirmed helplessly while pinned between his lover’s embrace and their foal’s weight. And due to the building pressure of arousal from Sombra’s hoof-work, Shining wasn’t able to control his words as he blurted with a moan, “I… I can’t say that… th-that you’re wronnnngggg…”

“That’s right,” purred Sombra as he pulled his muzzle up, and used his fanged teeth to carefully nibble on Shining’s ear. Despite how razor-sharp the ex-King’s teeth were, he was able to use them gently enough to only elicit a shivered groan from the increasingly randy stallion he knocked up. Between his legs, Sombra’s member was quickly slipping from its sheath from every cute noise he heard the Prince make. After Shining let out a weak and involuntary giggle, Sombra pulled away to whisper, “you can’t say that I’m wrong. Because I’m not wrong. If anything, being my adorable little Sub is almost a Public Service. You can’t have your big, dominant mate causing trouble outside of these walls, now can you?~”

Even with Sombra’s slightly threatening tone alongside his heated growls, Shining knew that the stallion wasn’t being serious by any means. Wording aside, the Prince understood Sombra’s humor well-enough to know he was just trying to rile him up. And given how much he enjoyed teasing, Shining just moaned sweetly while his stallionhood throbbed in his lover’s grip. “Mmnnnnghhh… You… You’re just trying to… t-to make me feel better about carrying your foal~”

“Maybe a little,” stated Sombra with an honest shrug while maintaining his lustrous grin. His thick, marbled member of ebony hue was slapping beneath his barrel repeatedly, now grown to its full rigid length; Shining may have been above average when it came to his own endowment, but it was still significantly smaller to the massive cock his baby-Daddy possessed. “But... I also think you don’t need an excuse to feel positive about yourself, my Prince. Foal or not, I think it’s clear you wanted me bad when we first met, right?~”

Shining groaned with an especially strong stretch of his hind-legs. His eyes were tightly shut, and his breaths were weak and rapid while trying to avoid answering that question. But alas, Sombra just gave the Prince’s cock several hard, diligent jerks to get him to answer honestly. “MMMNNNGHHHH… I-I-I… I may have,” Shining admitted while squirming in Sombra’s grasp. “Aaaahhhhh… A-At least a little…”

“A little?” Sombra asked in a tone bordering between curiosity and mockery. He then patted Shining’s pregnant stomach before pulling himself down towards the Prince’s legs. “I think your baby-bump suggests it was more than that, little Prince. Especially when I can recall just how loudly you moaned when I did… this~”

By the time he said that last word, Sombra had scooched himself off the couch to kneel in front of Shining on the floor. The Prince’s swollen stomach was less than a foot from the ex-Tyrant’s face, giving him a prime-view of that round and stretched-out belly carrying his patronage. And beneath that rotund proof of their affair, Shining’s cock was standing at full-mast and throbbing continuously. The former Tyrant licked his lips with a hungry groan at the sight of that member, recalling how similarly aroused the Prince was when they first indulged in physical pleasures.

And like a primal beast stop its claimed prey, Sombra growled out hungrily as he opened his fanged maw wide and bent in.

“MMMNNNGHHHH!!~” Sombra’s teeth may have looked intimidating to say the least, but the dark stallion was quick to curl his lips over those mandibles before wrapping his muzzle around a good portion of Shining’s twitching length. Even with his domineering presence, Sombra couldn’t help letting out a weakly-muffled moan as he started to suck on his mate’s pent-up member. The Prince gasped deeply to such a familiarly tantalizing feeling, and could only shudder while he laid himself back on his lover’s couch. Sombra tried to glance up at Shining tauntingly, but could only see that pregnant belly from the angle he had between the stallion’s legs. But alas, the ex-villain could still hear those shuddering groans as he opened his mouth, and wrapped his reptilian tongue around that thick shaft.

“AaaaahhhHAAAHHHH!!~” Shining writhed powerfully on the couch, unable to stay still from the former King’s uniquely amazing tongue. “Oh… Oh, Sombra~”

As he heard Shining moaning out his name as opposed to his wife’s, the ex-villain felt content enough with himself to smirk a little. However, he still kept his tongue wrapped around the Prince’s cock like a coiled snake, and let it disappear from sight as he sunk his muzzle back around two-thirds of the stallionhood’s length. Sombra hummed to himself in pleasure as he got a good taste of his lover’s previously untouched cock, unable to fathom how the Princess of Love of all ponies would keep it unattended for over a month. Although, even if she was servicing it semi-regularly, the ex-Tyrant was doubtful she had the skills with her tongue to compete with his own.

But even with his own thoughts in regards to his talents, Sombra’s ears twitched in delight at hearing his mate’s undoubtful moans of confirmation. The white pony’s hooves came down to grasp the top of Sombra’s mane, trying to keep him in place as that muzzle kept bobbing up and down his throbbing length. Of course, his forelegs were obviously obstructed by his bump, so his efforts were fairly fruitless when it came to establishing any control. Fortunately, Sombra continued to suck on his lover’s cock without any complaint, seemingly fueled by the elated noises Shining was making in response to each pleasurable motion of his mouth.

“Oh, Sombra~” he moaned out in an even deeper tone, clearly sinking deeper into the feeling of ecstasy his mate was giving him. “I… I can’t wait to be with you outside of this room…”

While Shining’s stallionhood was still in his mouth, Sombra made a muffled chuckle before deciding to pull back. As his muzzle opened and his tongue retreated, several strings of saliva connected his glistening fangs to the Prince’s twitching cock. “Neither can I, my love~” purred the stallion as he peered up to see Shining’s cutely-blushed expression. Meanwhile, the white unicorn finally reopened his eyes, and kept a half-lidded gaze on the ex-villain below him.

“Mmmmm…” As he locked his sights on Shining, Sombra licked his lips as a devilish idea crept into his mind. “Honestly... part of me wishes we could do something outside this room~”

Shining shivered with a worried blush deepening across his cheeks. Even without context, the Prince understood Sombra well enough to know what he was implying they should do. He gulped nervously as he tried to cross his legs shut, not wanting to give in to another one of the ex-Tyrant’s dangerous ideas. “S-Sombra, we… we really shouldn’t do anything too risky. If… If we were go outside, we migh--”

“Not outside, silly,” stated Sombra in interruption while growing a cheeky smirk across his muzzle. He began to pull himself up while clarifying his suggestion. “Honestly, doing that would be borderline suicide. I was just thinking that… since this entire wing of the castle has been vacated, that we could do certain things we discussed a while back~”

As he sat motionless on the couch, Shining shuddered cautiously while he felt his heart racing at a steady rate. Given all the things the two discussed trying after coming out with their relationship, the Prince honestly had to think for a moment to ascertain what Sombra was specifically referring to now. Meanwhile, his mate’s wickedly sly grin became more apparent with each second that passed between them. If he still had his horn (or more specifically, a level of magic beyond the court-mandated limits he currently had), Sombra would’ve easily just floated out the specific items he wanted Shining to indulge him with. But instead, the stallion had to pull himself up from the couch, and walk towards his nearby dresser.

Shining bit his lip while breathing through his nostrils, barely able to sit still due to his cock continuously twitching in its exposed state. As he watched Sombra walk away, his eyes were hooked on the sight of that thick, mammoth-lengthed cock that was swinging between the ex-Tyrant’s legs. “Wh… What do you mean?” he finally asked with a shiver, and an expression which gave no clear indication whether he was more fearful or peculiar.

“What I mean is…” Sombra’s grin was unmistakably devious when he opened the top drawer of his dresser, and pulled out a wooden box that Shining instantly recognized. Over the months they spent together, the Prince saw that box enough times to know it hid an assortment of rather… risquè items they used while together. As soon as the lid was opened, Sombra peered back at his pregnant mate giddily and continued his proposal. “... given how well-respected you are in this castle as opposed to me, it’s doubtful that any of your staff or guards would disobey orders and enter this wing, correct?~”

Shining knew where Sombra was going with this, and wanted to stay stern for the sake of their foal. But alas, the stallion could only gulp as he felt his head nodding blankly in response. “P… P-Probably…”

More of Sombra’s fangs could be seen as he smiled even wider. “Which means…”

That was when the ex-King pulled out the items he was searching for in the box. Upon seeing what Sombra had, Shining sucked some air through his teeth as his blush practically exploded across his face. Meanwhile, Sombra paused his words for a moment to marvel at his lover’s cute squirming. The former Tyrant watched as Shining’s eyes moved back and forth, following the movements of the black leash and collar hanging from the tip of Sombra’s waiting hoof.

While the items themselves were those the Prince could recall using several times before, his heart was thundering in uncertainty and shameful arousal as he heard Sombra suggest, “... If I were to collar you up, and walk you around the hallway like my little bitch… do you think any ponies would see it?~”

Shining let out a slow and shuddering breath while staring back at his domineering mate. He didn’t want to comply to such a risky idea, nor did he want to confirm Sombra’s earlier claim about him not being as strong-willed as he believed; unfortunately, the Prince’s composure proved to be rather compromised due to that earlier oral, and he couldn’t help shaking his head weakly. “N… N-No, probably not…”

“... And I take it those magic-barriers you ordered to be placed around this wing are also sound-proof?~” asked Sombra coyly, mostly to reassure Shining while coaxing him to comply properly.

The last thing Shining wanted was to be seen leashed and humiliated outside of this room, despite how badly his stallionhood throbbed at the very thought of it. Nevertheless, the stallion still nodded meekly while unsuccessfully trying to cross his legs shut. “Y… Yeah they are…”

“So what I’m hearing is…” Already antsy to give his wickedly randy idea a try, Sombra trotted back towards the couch. While he held onto the handle of his leash, Shining’s collar remained hanging tauntingly as it was dangled less than a foot from the floor. Even from his angle, Shining was able to see the golden bone-shaped tag hanging from the front of the collar, which had the word ‘SLUT’ lewdly inscribed in a bold font. The Prince’s eyes kept darting between that temptingly taboo accessory, and the gleaming grin Sombra carried as he held it before his mate. “... you know much better than I do how secure the perimeters outside this room really are. And with that in mind, you also know how minimal the risk would be if you were to go out wearing this. So the question that you have to answer for me is this…”

That was when Sombra leaned in close to Shining’s trembling, blushed expression. He waited until the two were within kissing distance before he licked his lips devilishly, and asked in a dominantly brooding tone of voice: “Do you want to do it?~”

Shining took a split-second to breathe in deeply, and kept his eyes on his lover while he exhaled cautiously through his nostrils. His heart was pounding like a drum in his chest, and he had to bite his tongue in order to get his thoughts straight. Even with how badly his cock was straining in need for release, now at the point of repeatedly whacking against the underside of his pregnant belly with each throb it made, Shining knew that he had to keep control. Knowing how monumentally stupid Sombra’s idea really was, even with all the precautions he made beforehoof to ensure they wouldn’t be seen, it didn’t take long for the Prince to open his muzzle and answer his mate’s in the sternest tone possible:

“Yes, I want to do it--EEP!!!” Shining obviously hadn’t expected to say that, and gasped in horror as his hooves cupped over his muzzle. Unfortunately, that answer was clear enough for Sombra to give a wide, shit-eating grin.

“Excellent~” Before Shining could even try to protest, Sombra placed the black collar around Shining’s neck and clasped it shut at the back. Even when the Prince pulled his hooves away from his mouth, he could only whimper as he felt that familiarly arousing constraint around his neck, and heard that distinct jingling of his ‘Slut’ tag dangling underneath his chin. His whole body was shaking in mortified titillation, but his stallionhood was throbbing even harder in obvious approval of Sombra’s plans. Since the leash was already connected to the back of the collar, all that the ex-villain had to do was get up from the couch, and smirk as he gave it a good tug to grab his mate’s attention. “Now get up, you little slut… I think you need to take a walk~”

Even with how much he was trembling in worry, Shining felt his pregnant body acting on its own as he nodded meekly. “O… O-Okay…” Much like Sombra would’ve claimed was going to happen, the Prince shivered with a deep-red blush as he grunted under his breath, and rolled himself off the couch to land on his hooves. With how bulbous his belly had grown beneath his barrel, Shining cringed at the idea of being forced to waddle completely exposed like Sombra’s pet in the hallway. However, before he could meet his fate and follow the former King out of the room, he shrunk back as he saw his lover standing over him with an expectant stare.

“Okay, who?~” he asked with a menacing grin.

If any Crystal Pony were to see that smile again, they would’ve likely wet themselves in fear or run away screaming. But for Shining, all he did was shiver with a massively turned-on smile. “O… O-Okay my King,” he replied quite timidly, which was more than enough to make Sombra smile with a satisfied chuckle.

“Very good~” purred the domming stallion as he gave Shining’s blue mane a grateful pat with his hoof. The submissive Prince blushed embarrassedly to that gesture, but remained in place before hearing his mate say, “Now, let’s get you out of this room, alright?~”

Shining didn’t say anything, but still nodded dutifully before following his Dom towards the door. Much like both of them expected, the massive hallway turned out to be completely empty after Sombra unlocked and opened the door wide. Even when the ex-Tyrant stepped out into the open with his erection in plain sight, and tugged on his leash to make his fruitful slut follow suit, it was clear they were the only ponies around. Shining wanted to be happy of such a thing, especially since he didn’t have his camouflage spell up to conceal his obvious pregnancy while leashed to the father. However, as soon as the two were out in the open in such a compromising position, the Prince couldn’t help feeling the slightest twinge of disappointment beneath his heavy veil of denial.

“See?~” asked Sombra with a more chipper tone behind his obvious grin of sadistic glee. “No ponies are around to see you right now… Especially not as the little cheating slut that’s carrying my foal~”

Shining’s legs buckled as he heard Sombra say that last part in a very deep, and very audible tone that echoed across the halls. If those magical barriers weren’t really sound-proof, Shining would’ve been in huge trouble due to his lover’s thoughtless tenacity. His lips were pursed tightly shut, and his cock was starting to leak precum as it slapped repeatedly against his massive belly. Meanwhile, Sombra waited a moment to make sure nopony heard them, and then tilted his head to ask in a sickly-sweet tone, “Isn’t that nice?~”

By that point, there was no use in trying to deny how hot the Prince felt from this level of exhibition. Even as he reached down with a hoof to rub at his pregnant belly for comfort, Shining still nodded his head meekly. “A… A-A little, I guess…”

“A little?~” asked the ex-King as one of his brows raised curiously. “Well, that’s not nearly good enough for me. So how about we get you feeling nicer by letting you lead the way, hmmm?~”

A faint, feeble excuse of a whinny escaped Shining’s clenched muzzle, but Sombra could also hear another couple light slaps of the Prince’s cock against his belly for being put in such a fretful spot. After a meager exhale, Shining blushed hard as he put down his hoof and began to walk ahead of Sombra. Meanwhile, the ex-villain kept a satisfied grin as he followed his fertie pet down the hallway, his own member just as hard as Shining’s with each step they took. If those magic barriers weren’t up, chances were good that at least ten ponies would’ve caught sight of their Prince as Sombra’s pregnant bitch by the time they reached the end of the hallway. But fortunately, just as they reached a perpendicular split in the hall, Shining didn’t see a single soul down either end.

“Let’s see... “ Sombra stopped right beside his Prince, and looked down both ends of the hall as well while tapping his chin in thought. “If I remember correctly, this hall leads towards the maids’ quarters if we go left. Meanwhile… the exit to this castle wing is to the right…”

Shining bit his lip with a wince when he heard his lover say that last part. As he made a quick glance back down the right side of the hallway, he saw how it curved to the right to avoid seeing the exit. If they were to go that way, they’d likely see the magic wall of blue magic by the time they went halfway down. That wall may have been sound-proof, but it was also transparent on both sides. The Prince shivered uncomfortably at remembering that detail, knowing that the Guards posted at that exit could easily look into the hall if they were to ignore their orders or leave their post.

The pregnant stallion wasn’t sure how long he was looking down that end of the hallway, even though he could’ve sworn it wasn’t longer than a second or two at most. However, that turned out to be long enough for Sombra to not only notice, but grow a mischievous grin while his mate wasn’t looking. He leaned his head in towards Shining’s head silently, and whispered into his ear, “What do you say, my naughty little colt… wanna go Right?~”

Shining sucked some air through his nostrils as he jolted from Sombra’s temptingly dangerous suggestion, not wanting to give in to what he knew the ex-Tyrant was wanting to do. Unfortunately, he wasn’t able to speak up before Sombra brought his hoof up and pulled Shining’s face towards his. As the white unicorn remained pinned before those burning, knowing orbs of red, his whole body trembled in a way that made his cock throb tremendously hard in intimidation. As for Sombra, his smirk stayed at a eerily wide length while narrowing his sights on the pregnant stallion in his grasp. “You’re already walking around in this hallway completely exposed, showing that baby bump and letting me leash you nonetheless. In fact, it’s almost as if you’re showing it off~ You know how dangerous that is, but you’re still willing to do it because it excites you, does it not?~”

Shining didn’t answer that question, but Sombra grinned even wider at seeing that involuntary twitch the Prince made in response. Because of that, he leaned in even closer while his hoof held Shining’s head in place. “And by the way you were looking down that end of the hall, it seems like you want the risk of being seen. You crave that excitement, don’t you?~ You want to be leashed within sight of the very guards you saved, and have me fuck you behind their backs... just like your wife~” 

The pregnant Prince may have not been able to move his face away from Sombra’s domineering stare, but he could still clench his eyes shut and groan weakly as he tried to deny such a thing. Of course, with how hot his face felt, he was sure that his body was clearly giving away how truthful the ex-King’s assumptions really were. Despite any truthful worries screaming within his conscience, they were overshadowed by the primal thumping of his heart as he envisioned giving in. Much like when he first kissed Sombra that fateful day, or that weekend he and the former Tyrant agreed to use that fertility spell from the book of Dark Magic, Shining already knew how he was going to answer as he heard his lover ask with malicious glee, “...right?~”

With the last of his resistance pushing out of him to make way for his overwhelming lust, Shiming breathed out in confirmation before opening his eyes to stare up at Sombra. “I… I do,” he said in a weak, albeit unperturbed tone of voice.

Sombra showed his glistening fangs once more, and smiled evilly in approval as he motioned towards the right-side of the hall. “Prove it~”

Despite the shaky breath he took, Shining was quick to waddle down the right side of the hallway while his face carried a deep crimson. Meanwhile, Sombra hummed contently as he walked in tow with a strong grip on the Prince’s leash. Even with the sound-proofing spell up, Shining’s heart pounded painfully as he heard that constant jingling of his tag hanging from his collar. But alas, all he could do was bite his lips shut as he continued to walk, and soon saw that transparent wall separating him from the rest of the unknowing castle.

He could clearly see two of the Crystal Guards in position in front of the wall, with their backs blissfully turned towards Shining’s line of sight. Despite his shamefully stupid desires, Shining couldn’t help sighing in relief that he wasn’t immediately spotted or caught. Nevertheless, he wasn’t able to stay relieved for too long before he heard Sombra clear his throat while behind him. “Now… How about you give a confession to that wall before we begin, hmm?~ Who knows? It might be good to say it out-loud outside of our living quarters anyway~”

Shining wanted to pout in annoyance to his lover’s toying, but he couldn’t deny how badly his spine tingled to such a thing. Plus, he knew that the sound-proofing spell upon that wall was ridiculously effective. So after closing his eyes briefly to take a breath, Shining exhaled sharply before he looked over at that wall. And more specifically, the outline of those two guards.

“I… I’m here!” the Prince blurted with a small cringe, which quickly disappeared when he saw zero movement from either guard. Upon that confirmation, Shining breathed out once more and said with a nervous smile. “I… I’m pregnant! I… I’m having an affair with King Sombra, and he’s the father of my foal!”


Upon saying those things out-loud and receiving no response, Shining exhaled with a bewildered smile before glancing back to his prideful lover. Sombra chuckled while holding onto Shining’s leash, and said as he walked in closer towards his backside. “Say what you’re planning to do towards that wall, and I’ll fuck you like an animal~”

By that point, Shining was grinning just as excitedly as Sombra was, and nodded before he turned back to the wall. He took a breath before shouting, “I… I’m gonna let Sombra fuck me! A-And… And I’m gonna raise my foal with him!! You hear me!?! I… I’M IN LOVE WITH SOMBRA, AND WE’RE GOING TO BE TOGETHER!!”

Before Sombra could give any further prompting, Shining bent himself over as best as he could despite his swollen belly. Meanwhile, Sombra watched with an elated smirk as he let go of Shining’s leash, and spat on his hoof to get his stallionhood nice and wet. As the ex-villain got himself lubed up, he watched in glee as the Prince spread his trembling hind-legs wide apart. Shining lifted his electric blue tail as he continued to shout in bliss within the empty hallway. “AND I… I WANT TO HAVE MORE FOALS AFTER THIS ONE!! PLEASE SOMBRA, PLEASE PLEASE FUCK ME RIGHT HERE!!!~”

Without warning, Sombra growled like a lion as he pounced his pregnant mate and immediately mounted him. While those two guards stayed in position with stoic expressions, neither of them seemed to notice their leader collared up and moaning out heavily behind them. Nor were they able to see their former Dictator atop of Shining, using him like his personal whore behind their backs. It was nothing short of a miracle that no ponies were walking past that closed-off entrance, or else they would’ve gotten a clear view of the Prince’s blushed face with his muzzle opened wide in response to Sombra’s quick penetration. Fortunately, that magic barrier kept all of the pregnant pony’s lustful moans contained within that closed-off wing.

“AAAAAHHHHHHHH!!!~” Shining’s eyes were clenched shut as he felt Sombra’s thick, crowned cockhead prodding hard against his puckering hole. Fortunately for the Prince, there was more than enough precum leaking from that massive tool to help aid in the impromptu lubrication Sombra gave earlier. Shining’s face scrunched in tightly in discomfort for a few seconds, making him wish his mate brought their regular lube along with his leash and collar. But after a deep groan, and one last push from the ex-Tyrant that made Shining scream out painfully, that meaty head managed to pop inside of the Prince’s tailhole with only moderate difficulty.

“Mmmmmnnnghhhhh!!~” Shining was struggling to adjust to that searing bout of pain as he groaned loudly to such a sudden intrusion. However, that soothing, familiar wave of numbness soon swept across the Prince as he shuddered from the feeling of Sombra’s cock filling him properly. He may have loved his wife dearly (and was even thankful when she used a strap-on a few times), but that measly rod of plastic did nothing to push his buttons like the former King’s hot, thick, meaty stallionhood currently throbbing inside of him. He may have sought out for that cock as often as he could get, especially recently while the due-date and inevitable reveal were drawing near; but alas, as he laid upon the hallway carpet moaning like a slut, with strands of his precum spurting out to stick to his pregnant belly, he honestly felt like it’s been too long since he felt that member he adored so much. “Aaaaaahhhhh~ Ohhhh… Oh, Celestia I missed this…”

“You mean my cock, or all of me?~” asked Sombra coyly while he was two-thirds of the way inside of his fruitful lover.

Shining let out a grunted huff while squirming in place, and smiled a little before answering, “B-Both… Mnnnnghhh, I realllllly need you right now…”

Sombra smiled warmly at hearing such a genuinely caring statement from the moaning Prince. And with a thankful sigh, he began to rub one of Shining’s flanks tenderly as he paused to say, “Well, given our situation, I think it’s pretty clear I need you just as much.”

The unicorn could tell that Sombra meant those words, but still huffed as he smirked cheekily up at him. “Y-Yeah, I have to agree. I mean… what’s a King without his Prince?~”

Despite how badly his body was shaking in need to plow Shining into submission, Sombra couldn’t resist answering with a shrug, “Well, probably a King with massive blue-balls instead of a brood-stallion~”

Shining giggled with a guilty blush before smiling more contently. “O-Okay, yeah… honestly, that would be a travesty considering how amazing you are~”

“Heh~ Even in moments like this, you can’t help being sappy.” Considering how pent-up both of them were, and how the chances of them being discovered were increasing with each second spent behind that transparent wall, it was surprising that either of them even stopped for this long to have a tender moment. Some ponies might consider that further evidence of their unconventionally taboo bond, but all Sombra seemed to care about was the pregnant stallion he was buried inside. The dark stallion kept his smile, but his hooves tightened on both sides of the Prince’s flanks as his eyes narrowed evilly. “Let’s hope you stay this dedicated after the foal is born.”

Shining knew that Sombra was ready to rut him like mad at any moment, but he still scoffed and replied, “What, you think I won’t? I’ve been yours since you impregnated me, my King~”

As if that statement wasn’t enough to make Sombra purr in satisfied delight, Shining then added with an especially pent-up tone, “As… As long you give me my fill, I’ll do whatever my King tells me~”

Sombra’s grin grew just as antsy as his brood-stallion’s. “Well, then…” His growl was accompanied with a lick of his fangs, and he said just before ramming into the Prince, “let’s make sure you live up to your WORD!!”

With that final push inside of the fruitful stallion, Sombra’s plump balls pressed in tightly against Shining as he drove his entire length inside that waiting hole. Shining yelled out in a strained cry of pleasure, and his face showed an unmistakably elated smile through his gritted teeth. “NNNRRRRGHHHH… Y… YES, my King!~ Ju… Just like that!”

Like a rabid bull intent on giving another breeding, Sombra was quick to pull his length back and cause his bitch to tremble in his grasp. Shining breathed in sharply through his teeth as he felt his lover’s thick crown sliding and scraping against his sensitive walls. His legs squirmed and writhed helplessly, just barely able to hold up his own weight and Sombra’s. But like a good little brood-stallion, Shining managed to stay in position as he felt most of that stallionhood leaving him empty on the inside. He wanted to whine needily for his mate to shove himself back in, but he knew that was inevitable when he heard Sombra’s low and intimidating growl above him. “You better moan out for me good, you little bitch~”

Fortunately for the pregnant stallion, Sombra’s warning demand proved to be unnecessary the instant he shoved his entire length inside of Shining in one massive thrust. The Prince’s nirvanic squeal echoed throughout the empty halls as soon as Sombra’s hips hit his backside with that meaty slap. His hind-legs almost buckled over from the intensity of how hard Sombra’s balls slapped against his own, as well as from the feeling of that veiny shaft rubbing against his prostate. His spine was tingling badly while his fur was standing on end, and his hefty moans were beyond audible as he laid in total submission for his lover.

Sombra was more than pleased with his mate’s slutty cries, and quickly repeated his motions to throw the Prince into a continuous cycle of pleasure and fulfillment beneath his grasp. Meanwhile, it was almost comical how oblivious Shining’s guards appeared as they stood in front of that wall of magic, unaware of their pregnant leader taking it less than twenty feet behind them. Even with that sound-barrier concealing the leader’s slutty moans and Sombra’s meaty slaps with each thrust, it was shocking that none of their heated motions against the castle floor made any shockwaves or vibrations that the guards could feel beneath their hooves. But alas, as the ex-villain’s thrusts intensified in both power and speed, it seemed that the Prince’s exhibitionistic debauchery might not be noticed by the time the two got finished.

Sombra growled out in strained titillation as he picked Shining’s leash back up, and made the unicorn squeal when he yanked on it hard enough to make him lift his head high. “Now… you’re going to listen to your King very clearly,” he hissed with a domineering voice into Shining’s ear as he continued rutting him rapidly. “Until that foal is born, my little bitch… you’re going to service me every day without exception. Understood?~”

“Ahhhhh… I… I understand, S-Sombra!” moaned the pony weakly as he endured those ever-intensifying thrusts his King was delivering to his hungry tailhole. While he knew it would be difficult to say the least (especially since he was only able to visit Sombra’s quarters once a week when he was lucky), Shining was willing to comply with Sombra’s order while feeling a couple faint kicks in his pregnant belly. He had no idea what would happen after he gave birth, but the stallion didn’t want to keep Sombra away from his future child any longer than necessary. Because of that, it was easy for him to moan out between his lover’s thrusts, “I… I promise I’ll make it happen… m-m-my… my King~”

“Good!” snarled the former Tyrant with a pleased grin as he pounded that fertile ass even harder with his muscled hips. Shining leaned forward enough for his head to press against the floor, but he still moaned out while his body rocked back-and-forth from those hefty thrusts. His own cock was throbbing and leaking sporadically, but the Prince could only let it dangle while his pregnant belly left it out of reach. Meanwhile, Sombra was continuing to grind against Shining’s prostate with each thrust inside of him, stimulating the pony hard before he said, “And as long as you’re servicing me, I think it’s clear your wife is off-limits from now on… She hasn’t given you any pleasure recently anyway, so you can hold off on her until you give birth, right?~”

Even with how close Sombra was rocking his body towards the brink of orgasm, Shining’s muzzle still wrinkled in slight discomfort to that measure. The ex-villain wasn’t particularly wrong about her lack of attention, but the idea of forbidding his wife from having sex with him sounded a bit much. Of course, considering how far he had sunken into adulterous shame with a former enemy, he knew that she was likely to leave him as soon as she discovers the truth. That realization was never easy to think about, but he was able to grit his teeth and groan before agreeing to Sombra’s deal. “O… O-Okay then! I… I promise I won’t Sombra. F… F-From now on, the only pony who touches me is you!”

“Goooooooddddd~” Sombra was grinning especially wide after hearing that answer, which was satisfying enough to make him grow closer to his own climax. With each brutal smack of his hips against Shining’s rear, and every wet slap of his balls against the pregnant Prince’s, Sombra could feel his cock throbbing harder between his thrusts. He knew he was going to unload into Shining sooner than later, and his breaths grew more rapid as he picked up the pace. But before he could claim his lover once more with his once-Royal seed, the ex-Tyrant groaned out in pleasure before asking, “Who… Who’s my little slut, Shining?!”

“Ahhhhhh!!!~” Shining Armor moaned out like a mare in heat, and his body shivered in delight at hearing his mate teasing him alongside those brutal fuck-strokes. He wished he could stroke himself despite his position, but he was still overwhelmed with pure sensual bliss as he moaned shamelessly, “I… I’m your little slut, my King!~”

“That’s right!” roared Sombra with a maniacal grin. He’d normally smack Shining’s ass as a reward for that compliance, but the pony’s pregnancy made that idea too off-putting even for him. So instead, he gripped those plump cheeks even tighter in his hooves, and continued pumping his stallionhood inside of Shining like a jackhammer. Fortunately, the sounds of Shining’s primal cries of elation proved that he wasn’t upset by the lack of spanking by any means. With each hard thrust in and out of that needy tailhole, Sombra had to bite his lip briefly before grunting, “Te… T-Tell me you’ll keep holding my lineage!~”

“Aaaaahhhhh!!!~ I… I promiiisssseeee!!~” Shining was completely lost in his own demented pleasure, seemingly oblivious to anything around him while within his oasis of dark titillation. Fortunately, Shining and Sombra didn’t seem to be caught yet within the vacant hallway, even after Shining moaned out deeply, “I… I want you to keep knocking me up! As… As soon as I give birth, I want another foal in me, PLEASE!!~”

As he belted out those taboo statements behind the backs of his still-unknowing guards, Shining’s cock throbbed even harder as he reached the tipping point of his inevitable finale. And judging by the erratic tempo Sombra was starting to show with his heated thrusts, it seemed that he was growing close as well. The dark stallion’s breaths turned more ragged, and his legs were tensing up from each strong pulsation of his member inside of Shining. “I… I’m getting close Shining!” roared the former King through his clenched fangs. “I hope that… that you’re ready to show your worth!”

“I… I always do!” cried out the Prince, unable to even try pulling his face from the floor as he endured those final monstrous poundings by his lover. “I… I want to be yours, my King! I… I don’t want anypony else but you!!~ I WANT YOU SO BAD, SOMBRA!! I… I!!”

Before Shining could finish his honest beltings, Sombra roared out like a beast as he pushed his full length inside of the pony as hard as he could. With that final thrust inside of him, and that last massive grinding of Sombra’s cock against his throbbing prostate, Shining could only gasp before groaning in pure intensity. He could feel his cock pulsating without ever being touched, and he clenched around his mate’s stallionhood as tightly as he could while screaming, “... I LOVE YOU SO MUUUUUCCCCHHHH!!!~”

“I… I LOVE YOU TOO!!” shouted Sombra as he gave in to his body’s desire to breed the horny Prince once more. Despite how out in the open they were, and how clearly he could see those two guards through the transparent wall in front of them, Sombra’s orgasm swept across his body hard enough to make him belt out a wall-shaking roar. His body froze as it locked tightly against the pregnant stallion’s, and his cock erupted inside of the Prince’s deepest depths to deliver a massive volley of his thick, virile seed. Sombra couldn’t say anything more than that final statement as he shuddered from each electrifying pulsation of his climax, causing his fur to stand on end and his prosthetic horn to heat up from the stump it was covering. He may have not been able to use his magic anymore, but that orgasm was more than enough to make a few rare crackles of magic pop from his fake horn like a cheap fireworks display.

Meanwhile, Shining was completely lost in bliss as he came powerfully from the massive filling his lover gave him in the heat of their exhibitionist displays. Every nerve in his body tingled like crazy as he came from the sensation of so much warmth flooding inside of him, reminding him of how many times Sombra did that to get him pregnant the first time. Speaking of which, by the time the Prince was finished with his intense and invigorating orgasm, multiple strands of his cum were lewdly splattered and smeared across his swollen belly. The stallion had also created a ridiculously large puddle of his seed between his legs, which was soaking into the carpet at a rate Shining knew would make cleanup a royal pain.

Nevertheless, while the Prince knew that those measures would have to be met before the wing can be un-blocked, he also knew that he and his lover needed a moment to come down from their wild lovemaking session. So despite the waiting guards remaining at post right in front of them, Shining remained contently spent while savoring the warmth of Sombra atop his back. Meanwhile, the dark stallion was purring to himself with a pleased grin, occasionally twitching as he shivered from the tightness of his mate’s hole still wrapped around his deflating member.

“Mmmmnnnghhhh…~” With a more peaceful smirk on his muzzle, Sombra leaned down to give a light peck to the back of Shining’s sweat-matted neck. While the Prince giggled from that gesture, Sombra asked, “So… you happen to know that cleaning spell by memory? Because I don’t want the maids to see what you made and start growing suspicious.”

“D… Don’t worry,” muttered the unicorn in a winded tone before turning his head to look up at his mate. Shining gave his love a genuine, albeit weak-looking smile before he said assuredly, “Trust me, Sombra. I’ve learned quite a few spells since you got me pregnant. No matter what, I promise you that nopony will know about us until--”

“Shiiiiiiiniiinnngggggg!!”

Upon hearing that faint, but very noticeable voice of Princess Cadance in the distance, Shining and Sombra both froze in immediate panic. Their eyes were widened with looks of unbridled fear, realizing that the pregnant Prince’s wife had somehow entered this wing of the castle unexpectedly. Before either of them could move, they also heard Flash Sentry’s voice saying something to Cadance's.

“Cadance, you know that Shining prefers his privacy when he’s with Sombra. Coming in here unannounced will only upset him.”

“Oh, don’t be so paranoid. I am his wife, after all! Besides, why would he be upset to see me? I just wanted to check up on Shining, and give Sombra these chocolates as a peace offering. After all the time I spent avoiding him, it seems like the nicest thing I could do.”

Unbenounced to either of the ponies, Shining and Sombra remained in the middle of the hallway right behind that magic wall, unable to move without the risk of being heard by her. Not to mention, her presence might make those guards in front of them move from their post at any moment. Shining Armor’s face paled in unfaltering horror, envisioning a million different scenarios in which he and Sombra’s lives would be ruined upon being discovered. Meanwhile, Sombra stayed deathly silent for a moment before slowly leaning his head down.

“Shining… Pleeeeeeaaasssssse tell me that you know an invisibility spell...”

Sombra wasn’t able to see how much Shining’s pupils shrunk in horror, but that bout of silence was more than enough for him to realize the unicorn didn’t. Instead, all that Shining could do was exhale sheepishly and say, “Oh… fuck.”


The End
