While the party continued in full-swing inside of the ballroom, Princess Cadance saw it best to make her leave a little early after the speeches were complete. Fortunately for the fruitful Alicorn, she was escorted away from the cheerful festivities by her husband, as well as a slightly shell-shocked Shining Armor. Even though she only partially knew of Sombra leading Shining on before the party, she hoped that the Guard wasn’t too overwhelmed by her theatrical key-breaking to not appreciate her commitment to their relationship. Or at least, she was hopeful that he could look past it quickly enough to continue on with the same tenacity as before.

As for Shining himself, it was clear that he needed a moment to fully process what he just endured over the course of the night. While he knew that his key had to be broken due to his agreement to both Sombra and Cadance, he honestly didn’t expect it to occur so soon following her confirmed pregnancy; not to mention, he certainly wouldn’t have predicted her doing it in such a grand gesture with nopony being the wiser. Nevertheless, the Guard knew that despite his disappointment, he sorta brought that onto himself when he didn’t read between the lines of Sombra’s vaguely-worded promise to him earlier. So despite how badly his member ended up aching within that now permanent encasement, Shining only needed a moment to let reality sink in while he followed Cadance and Sombra out of the ballroom.

Fortunately for the three, the rear hallway meant for castle staff was completely barren as they made their way through the back doors to leave the event. Because of that, Cadance wasn’t above playing up Shining’s new status as she turned around with a cheeky smirk and asked, “So, Guard… have you made the proper arrangements for us?~” With that last word, the Princess’ grin widened as she extended out one of her wings to wrap around Sombra’s back; the Prince replied with a giddy shudder, and grinned back at his wife while rubbing against her side rather unsubtly.

Shining sucked some air through his teeth while looking between the randy couple, and the dangerously unlocked door behind the three. But alas, the stallion was able to breathe out with a sharp huff before stating, “I-I, ummm… I talked with Twilight and my parents, and they agreed to look after Flurry Heart tonight. I also made sure that no Guards or staff would be in our wing of the castle tonight.”

Despite how frazzled he may have still felt, Shining was able to give a light smile towards the Princess following that statement. Meanwhile, Sombra narrowed his eyes on the Guard before he asked with a grin of his own, “So, Shining… would you mind me asking why in absolute Tartarus you decided to wear that for your speech?!~”

Shining’s eyes widened worriedly, and he glanced downward to realize he was still wearing that pink collar around his neck. The married couple giggled with impressed smirks while looking back at their cuckold, whose face ended up growing a heavy blush of red upon realizing what was wrong. Sombra could see just how quickly Shining’s pupils shrunk inward, and he covered his mouth to keep his laughter from growing too audible. Meanwhile, Shining’s left eye twitched a little before he was able to open his muzzle and try to speak. “W… W-Wait, you… you mean…”

“Psssh!~” Sombra scoffed with an obvious roll of his eyes, and shook his head as he replied, “Wait, did you think I meant for you to do THAT as part of your ‘payment?’ Shining! I… I’m not gonna lie, I’m more upset that I didn’t think of that myself!”

Sombra then reeled his head back as he laughed more heartily, which left Shining to lower his head like an embarrassed pup that piddled on the floor. Cadance had to cover her mouth as she snickered as well, but was able to sigh before she gave a more informed response. “Actually, I… I think he was hoping that you’d offer to be leashed from here to the bedroom. Granted, I didn’t hear the conversation you two had myself, so I’m sure there was some context that was misheard. Personally, I was against the idea since I thought it was too risky, but…”

After shaking her head with a befuddled smile, Cadance could only shrug as she said, “You know what? Considering what you just did, I think you made Sombra’s idea seem downright amateur!~”

Shining may have still felt awkward about his impromptu moment, but that jab from Cadance made him giggle bashfully as well. Sombra made an offended-sounding huff as he gawked at his wife in shock; however, considering how truthful Cadance's reply really was, Sombra merely groaned and rolled his eyes away from the Princess and her Guard. Eventually, Shining was able to speak up while he sheepishly tugged at the side of his collar. “Heh heh… W-Well, ummm… All that Sombra told me was to, errr… make use of what I had before the event was over. And I… I kinda assumed he meant before the three of us left.”

Cadance made a quick glance back at Sombra upon hearing that answer, which caused the Prince to clarify with a shrug, “Hey, I meant before the event was over. Technically speaking, the party is still happening, so it’s not like I was wrong.” However, despite how cheerfully Cadance shrugged her head in acceptance of that misunderstanding, Sombra sighed before returning his attention back to Shining. “But, umm… honestly though? I can’t deny that what you did was absolutely outstanding, Shining Armor. Even though I wouldn’t have expected you to accept your place so openly until after your key was broken, we’re both still proud of you nonetheless.”

Shining blinked a couple times, almost taken aback when he saw the genuine smile that Sombra was giving him. Cadance's wing may have still been draped over the Prince’s back, but her smile towards their Guard was just as caring and prideful as Sombra’s. “I have to agree with him on that one, Shining. I mean, I’m just as surprised as he was that you did it, but… I’m also really happy that you’re able to embrace yourself for who you are~”

The Guard raised his brows after hearing both of the couple’s sincere words, and eventually grew a more content smile as he nodded back at them. Despite his embarrassed blush, Shining still breathed out less shakily before he said, “Ummm… W-Wow, uhhh… I… I guess it’s a good thing nopony caught on, huh?~”

Sombra chuckled as he nodded back at him firmly, and added in a cheekier tone, “Well, the fact that you chose not to wear your tag or leash may have helped out a lot with that~”

Shining’s muzzle wrinkled tightly as he looked away from his Prince, and tried not to groan in pained realization that he almost did do that. Luckily, Cadance was able to remain supportive as she tried to catch the stallion’s attention. “Well, that doesn’t change the fact that what you did was really brave. And… I just hope that you don’t have any regrets about it.”

That last remark made Shining’s brows raise in thought, and he looked down at the ground between himself and the couple to process how he felt. His heart was still racing rather fast, but that was mostly because of how he still felt from Cadance's little key-trick. But upon thinking back to that speech he gave, and just how he felt as he stood before everypony in his collar, the Guard honestly couldn’t say that he felt any shame about his choice. Even if it wasn’t what the Prince had planned for him, Shining was certain that he’d most likely do it again if he had the chance.

Not to mention, regardless of whether or not that key was gone, Shining was fully aware of where he stood among Princess Cadance and Prince Sombra. Back at that party, the Guard felt absolutely no regrets about expressing himself as best as he could. He may have not been stupid enough to actually admit who he was before everypony, but that didn’t mean he wasn’t alright with showing himself to the few that knew. And at that very moment, Shining Armor wasn’t too worried about his pride as he looked back at the Alicorn, and shook his head with a smile.

“I… I honestly can’t say that I do, Princess Cadance,” he said in a polite and cordial tone, just as a Guard should address a married mare of Royalty. While Cadance smiled back at him with a glimmer of pride, Sombra grew a satisfied smirk upon seeing Shining’s look of acceptance. The stallion took a deep breath while standing before the two, and sighed before standing in a more upright stance. “In fact, I... I wouldn’t be against complying with Prince Sombra’s idea too.”

Both of the couple’s eyes widened in surprise, with Sombra looking absolutely delighted by Shining’s newfound pride. “Oh, my goodness!~” he said with a cheeky grin more reminiscent of Discord’s. “You even addressed me properly in public! That’s quite an impressive feat~”

While Shining’s head lowered sheepishly with a blushed smile, Princess Cadance took the liberty of lighting up her horn for some added protection. Even if the three weren’t being eavesdropped, the Alicorn made sure to lay out a quick sound-proofing dome over them just in case. As soon as the three were encased within her blue aura, Cadance smiled at her Guard and said with a smirk, “Well, then… I’m guessing you don’t mind how I broke your key anymore?~”

Shining sighed again before shaking his head without hesitation. “Umm… A-Absolutely not, my Princess,” he tried to say confidently, even though his timidness could be heard behind his growing blush. When he brought his head back up, the Guard was able to breathe in before adding, “I… I’m fully aware of my place~”

That response made Sombra grin mischeviously wide, and he leaned in with narrowed eyes while the three weren’t able to be heard. “Say it, then~”

Shining nodded his head with a smile up to his Prince, but he lit up his horn before he could open his mouth. The Guard used his magic to float out the tag and leash from his jacket pocket, and dutifully put them on his collar without being asked. As soon as his “CUCK” tag was hanging prominently across the top of his tie, and the other end of his leash was floated over to Sombra’s hoof, Shining Armor carried a prideful stance while he said with a blush, “I-I’m a cuckold! And… My place is to serve the two of you however you may please~”

Even though the stallion felt unbelievably flustered by saying such a thing so openly, the addition of that sound-proofing dome made his truthful statement come out much easier. Cadance giggled with an enamored smile as she used her free hoof to pull Shining in, and give him a much-deserved hug. Sombra reluctantly gave the Guard a couple pats on the back as well, but made sure he had a tight grip on Shining’s leash as he gave it a hard tug. The pony was pulled back with a surprised grunt, and was soon met with Sombra’s wide and unrelenting grin. “If that’s the case… I intend to see you lead the way for us as we go back to our bedroom~”

Shining’s smile may have stayed spread across his face, but it was obvious that order made him freeze up with a clear look of fear on his face. Even though ninety-five percent of the castle staff were back at the party, Shining knew for a fact that there could be several Guards posted around the perimeter on the way to their castle wing. Not to mention, the stallion originally thought that he would be beside Sombra and his wife as he went back with them; but with the realization of him being leashed out in the open, even his acceptance of being a cuckold wasn’t enough to cover how worried he felt about Sombra’s demand.

Fortunately (or perhaps, unfortunately in Shining’s case), Cadance seemed to show support for her husband’s plan as she bent in close to the Guard’s face, and asked with a sympathetic smile, “Oh, Shining… aren’t you proud to be our little cuck?~”

Shining’s head lowered in growing nervousness, and his blush didn’t dissipate for a second as he meekly nodded his head up at her. “... y… yes I am…”

“And do you want the chance to stay by our bed,” she continued with a growing grin, “and watch what Sombra does with me?~”

The stallion closed his eyes and sighed with a look of defeat, unable to even contemplate being given the same treatment he experienced in Canterlot. So despite his justified worries, Shining nodded once more and said, “M… M-More than anything, my Princess…”

With that answer said clearly enough for Cadance's approval, the Princess unlit her horn so the sound-proofing dome was gone. She then stood proudly beside her grinning Prince, and pointed down the hallway while giving her command. “Guard Shining Armor, I hereby order you to lead the two of us to our bedroom! You shall not stop until we reach our elevator, and you shall not make any direct contact with any ponies we might come across. Do I make myself clear, Soldier?~”

Shining may have felt absolutely fearful about what he was about to do, but he wasn’t above complying with his Princess after coming this far. Since he was already far past the point of no return, the Guard didn’t try to show any reluctance as he breathed out in compliance, and bowed before the married couple. “Y… Yes, my Princess! I… I understand completely…”

With that, Shining took one final breath before standing back up with his collar and leash fully exposed for the outside world. Even though he knew just how dangerous this moment could be for all three of them, the Guard managed to soldier on as he began walking ahead of Sombra and Cadance. By the time his leash finally spread out long enough to stop touching the ground between its two points, Sombra finally followed his Guard while Cadance nestled in close beside him.

“Mmmm…” The Prince grinned devilishly as he peered back at Cadance, and made sure Shining wasn’t listening in as he whispered, “You did plan out the route so no Guards could see him, right?”

Cadance scoffed as she stared back at him with a disbelieving smirk. “Honey, of course I did! I might’ve let you knock me up, but I’m not stupid~”

The Royal couple may have been aware that the risk of Shining’s exhibitionist display was fairly minimal, but the Guard himself was infinitely on edge throughout his walk between the ballroom and their castle wing. Even though Princess Cadance made sure that their route was clear of any Guards or stray castle staff to spot them, Shining was as fidgety as a housecat as he peered past every corner in growing worry. Meanwhile, Sombra and his wife couldn’t help snickering silently as they watched their cuckold struggling to comply with their demands as obediently as he could, while also keeping their illicit debauchery hidden to basically nopony. Not to mention, the sight of Shining’s plump and bluish-hued balls made Sombra smirk knowingly to the fact that he’ll never use them again.

By the time the three finally arrived to the unmanned elevator, Shining’s breath of sweet relief was beyond heavy when he finally stepped inside the metal structure. Sombra didn’t say anything as they walked in behind the Guard, but their antsy smirks made it clear that he wasn’t going to feel too relaxed soon enough. As soon as the grated doors closed behind them, and the elevator made its slow ascent to their floor, Shining was barely able to breathe before the married couple took advantage of their “privacy.” Without warning, Sombra grabbed Cadance by her shoulders as he pushed her onto her hind-legs, and rammed her back against one of the confined walls; he then lunged in with a lustrous growl as he locked his muzzle with hers, and began to ravenously make out with the Princess in front of the flustered Guard.

Shining’s blush remained just as deep as it was during his walk, and he could only stand awkwardly while he stared at their passionate makeout session. Cadance latched onto Sombra’s back tightly with both hooves, and moaned through their heavy kiss while her eyes rolled back in passion. Sombra didn’t relent as he continued to hold her with a rumbling growl, and only pulled back just enough to let Shining see his tongue creeping into her open mouth. Of course, the leashed pony could also see his Ex’s tongue slipping into Sombra’s mouth as well, which caused his hind-legs to squirm in slight discomfort. Nevertheless, the pony’s enjoyment could be clearly seen while his lips were bitten tightly shut in arousal.

“Mnnnnghhhhh~” Sombra pulled his lips back from his wife’s muzzle with a wet pop, and left her panting heavily while he eyed her with a lecherous grin. “Ohhhhh Cadance~” he said with a deep and animalistic purr, which Shining could tell was making her shiver antsily. “You have no idea how badly I wanted to eat you out during that dinner~”

“Aaaahhhh!!~” Cadance reeled her head back as she moaned impulsively, not even looking back at Shining to see his blushed reaction to that remark. “Ohhhh, Goddess!~” she said with a shudder and a wide grin, which was still glistening with her husband’s saliva. “I… I really want you to do that next time, honey~”

Shining’s face contorted from the strain he was experiencing both emotionally and physically, but he kept his eyes locked on the two as they openly conversed in front of him. “Oh, really?~” asked Sombra as his grin on her grew even wider. “When you say ‘next time,’ do you mean the next time we have a fancy dinner? Or the next time I impregnate you with my foal?~”

Cadance was looking unbelievably riled-up while she was braced against the elevator wall, and Shining could see her legs buckling under weight while she moaned, “B-BOTH!~ I… I want you to do whatever you can to me in public!~ Mnnnghhh… I… I’ll order our Guard to stand watch~”

Shining had to bite his hoof while he quivered antsily to that suggestion. Not only was the idea itself hot as Tartarus, but the fact that Cadance suggested such a thing like he wasn’t even there made him feel unfathomably small in comparison to that domineering Prince. But despite that subtle twinge of despair the pony felt clenching around his heart, it was nothing compared to the primal throbs from his cock while it was locked inside of his unbreakable chastity.

“Then it’s settled~” growled Sombra before he lunged back in, and made out with Cadance just as vigorously as before. While one of his forelegs kept the Princess pinned against the wall by her back, his other moved down to tightly clasp between her quivering legs. The Alicorn gasped with a sharp moan the instant she felt that unexpected invasion of his hoof, but she didn’t seem to mind at all as she kept kissing him deeply. Meanwhile, Shining was left to tremble with a faint moan as he watched the Prince grind his hoof invasively against his wife’s already soaked marehood. Then in a moment of shock, Shining gasped with a very high-pitched shiver the instant he felt his “bracelet” vibrating around the base of his cage again.

Oh, shit! Thought the Guard to himself in a panic, realizing how badly he was going to hold up upon remembering what he was still wearing. I never took off Twilight’s ring!

“Mmmmmm… Is that what I think it is?~” purred Sombra as he gave a delighted grin towards Shining’s writhing state. Cadance was growing thoroughly riled-up as Sombra kept digging his hoof between her delicate folds, but she was still able to giggle upon realizing the same thing her husband was. Since the Guard was too busy squirming through his strained whimpers to reply to Sombra’s rhetorical question, the two went back to sloppily kissing in front of him. The distinct sounds of schlicking could be heard over the couple’s primal makeout session, but it was the growing scent of Cadance's arousal that left the poor Guard trying his hardest not to quiver enviously.

While Sombra kept rubbing his wife’s clit and leaving her direly on-edge, he held her close as he pulled away again and said, “I swear… Given how eager you are to let me pleasure you whenever I please, I’m surprised you didn’t divorce that pathetic cuck sooner to be with me~”

Shining heard a muffled grunt escaping his own muzzle while he tensed up from that teasing statement, but the Prince didn’t seem to pay any heed towards it. Meanwhile, the Princess let out another shivering moan while she squirmed on top of Sombra’s hoof, and said with a blushing grin, “Hehehehe… W-Well, it… it certainly wasn’t hard to take the opportunity when he begged me to do it for him~ Mnnghhh… Y-You should’ve seen how badly he was squirming to let a REAL stallion take me~”

Even with how hot the action was getting, Shining had to look away with a pursed muzzle following that response. He knew that Cadance was just trying to get him riled-up and humiliated for the sake of both his and Sombra’s pleasure, but it still made him feel so defeated as he thought back to that night. While he meant for that discussion to be a respectful agreement between husband and wife (which it was at first), Cadance soon took advantage of his compliance to test just how submissive he could’ve gotten for the opportunity. And while he certainly didn’t regret his decisions (even after knowing it would bring him to this), it was still jarring to think about how drastically a relationship could change in the span of a single night.

Luckily for the Guard’s conscience (as well as his chances of losing focus on the couple he was privileged to witness up-close), a sharp yelp from Cadance helped him stare back towards the antsy couple. Sombra slowly dragged his tongue up the length of Cadance's outstretched neck, and left her squirming with a bitten lip while he said, “Ohhhhh, my sweet and lovely wife… How did you ever manage to feel some proper satisfaction before me?~”

Even though the sight of Sombra eyeing Cadance so lustfully made Shining instinctively wince, that reply made him breathe out with the slightest hint of clarity through his nostrils. Even if he submitted himself to chastity through questionable means, the sound of the Princess’ blissful moan made it clear to Shining that he made a sound decision. As the Guard was left fidgeting badly and biting the inside of his cheeks, he tried not to whimper in jealousy as he heard her reply, “Oh, honey… I couldn’t imagine anypony pressing my buttons like you! Especially not our Guard anymore~ Hehehehe…”

Shining tried not to inhale too sharply through his teeth, even though it was clear from his strained expression that his Princess’ remark was beyond insulting. Even though he wanted to feel offended, the Guard’s ring continued to pulsate alongside the consistent intrusions of Sombra’s hoof into that wet and gushing pussy. With each hard press of the Prince’s keratin between her supple lips, and every enamored moan the Alicorn let out in response to those titillating motions, Shining could barely stand still while his bracelet kept buzzing incessantly beneath his aching cock.

After what felt like an eternity within that confined space reeking of Cadance's sex, the elevator finally dinged upon reaching their floor. The grated doors automatically opened to reveal the empty hallway leading to their bedroom, and no Guards to catch their former Tyrant groping their current Princess. However, even while the doors remained open, Sombra and Cadance continued to make out in the open as their lustful moods heightened with each passing second. Meanwhile, Shining looked between the open doorway and the antsy couple while his legs fidgeted in growing agitation.

“Ohhhhhhhh, Sombra!~” Cadance’s blissfully eager voice echoed down the crystal hallway as she made that boastful exclamation, not caring one bit if any ponies were within earshot to catch it. Even though Shining winced uncomfortably with his ears pulled downward, he could only stand in place while Somba kept a tight grip on his leash. Meanwhile, his former wife continued to moan needily between her lustful kisses with his former enemy. “Goddess, you… You have noooo idea how badly I need your cock right now!~”

Sombra pulled back from Cadance’s muzzle unexpectedly, and remained on his hind-legs as he backed up against the opposite end of the elevator. The Prince unbuckled his belt, and quickly pulled down his trousers to let his throbbing erection stand out in the open. Despite not being in their bedroom yet, Cadance immediately got down on her hooves while she eyed that superior stallionhood hungrily. While the Princess groaned in pleasure and licked her lips, Shining was pulled in tightly enough by his leash to wind up standing right beside Sombra on his hind-legs too.

“GUARD!” barked Sombra as he turned his head towards him with a domineering glare. “Pull down your pants too!”

Shining tried not to moan with a shameful grimace, but he complied to his Prince as he nodded his head. “S-Sir, yes Sir!~” Without any way refusal, Shining fumbled with his hooves a little as he tried to get his pants undone as well. After a few seconds, Cadance was left smirking with a giggle as the Guard’s pants dropped to his hooves, and his chastity cage was completely exposed next to Sombra’s massive cock.

“Daaaawww!~” From the way Cadance cooed at Shining’s petite plastic casing with such a condescendingly sweet tone, it seemed like she saw that unusable nub as a little trinket more than she did an actual cock. The Guard wanted to cringe when he saw how hard his Ex was struggling not to giggle, but her blushed and amused grin caused him to only whimper feebly. Between his quivering legs, Shining’s sealed cage twitched incessantly while his stallionhood tried to make itself known within its pink prison. Unfortunately, the only response his strained throbs elicited was a teasing flick from the Alicorn’s hoof. “Ohhhh, look at his little thing, honey! It’s like he’s trying to get himself hard for us~”

Shining’s ears pulled downward again, and his face grew hotter when he heard Sombra cackling beside him. “Well, he better try to remember how that used to feel for him. Because as far as I’m concerned, our Guard will never be erect again~”

Sombra made sure to get in close to Shining’s ear with that last emphasized statement, which caused the Guard to shudder with a pained look and a tightly bitten lip. Meanwhile, Princess Cadance kneeled herself down between the stallions’ vastly contrasted members as she smirked teasingly up at them, and gave a firm nod of her head. “Oh, I certainly hope not either~” she said with an especially mean-looking grin as she locked eyes with Shining’s flustered expression. “By this point, I don’t think he deserves that kind of distinction~”

Despite how horribly callous she said that with such an enticed-looking smile, Shining’s legs buckled while he tried to withhold a deeply aroused moan from escaping his muzzle. Unfortunately, the poor Guard’s shameful shiver before both of them made it obvious that he may have felt the same way the Princess did. As soon as the stallion breathed out with a trembling huff, Sombra stood upward more prominently while his eleven-inch monster dangled in front of Cadance's face. “Well, that’s most likely for the best,” he said as he gave a cocky grin towards his whimpering guard. “Hey, honey… do you think our Guard deserves a little lick from his Princess, for not abandoning his duties during harsh times?~”

The Guard breathed in sharply through his nostrils, and he tensed up greatly while his little cage began to dribble a pathetic-looking string of precum from the slated tip. Even though he didn’t want to get his hopes up, Shining still trembled as Cadance looked up at him with a thoughtful smirk, and brought her hoof out slowly…

… only to grasp the throbbing length of Sombra’s superior shaft while shaking her head. She grinned even wider as she stared up at her Guard, and replied with a deceptively cheerful, “Never~”

Shining couldn’t hold back his guiltily audible moan as soon as she said that, nor could he keep himself still as he watched his Princess lean in and sink the plump head of Sombra’s cock into her hungry maw. Her mouth opened wide to make that meaty cockhead fit inside, but Shining could see just how far her lips had to be spread apart while it was tightly wrapped around that daunting thickness. Her eyes closed as she stopped paying any heed to her Guard, and she focused on her husband while moaning to herself softly. While Shining stared with a heavy breath down at Cadance, and watched her use her muzzle on that member like she had many times before, Sombra groaned with a satisfied grin as he reeled his head back and savored the moment. “Mmmmm… That’s a good wife…”

Sombra brought his free hoof down to grip the back of Cadance's mane, and held her in place while more of his massive cock was crammed inside of her mouth. Shining could only squirm while he struggled to stand on his hind-legs, and had to keep his muzzle clenched shut to counteract any enamored noises that could’ve accidentally slipped out. But even with his eyes glued to that debaucherous sight unfolding right beside his locked and needy cock, all that Shining could think about was that last response Cadance gave up to him.

Never…

Never…

Never again~

“Nnnnghh!!~” Shining clenched his eyes shut as he writhed strongly from that realization, knowing that he likely never would be able to use his own stallionhood again. He wanted to feel mortified by such a cruel fate, but all that the Guard could feel was a strong and lingering sense of closure combining with his aroused shame. Even though he knew that he wanted to use his cock again, even for just one last time, the dire truth of the matter was leaving him more pent-up and eager than he ever felt in his life…

And he couldn’t deny to himself how much he liked that.

“Aaaaahhhhh…” While the Prince had his back braced against the wall and Cadance blew him vigorously, he reached into one of his jacket pockets to pull out his key to the bedroom door. “Sh-Shining,” he groaned in growing arousal while he kept his eyes closed, not even bothering to look at the trembling Guard while enjoying his blowjob. “Guard! I… I have a surprise waiting for you in the bedroom. G… Go inside and put it on immediately. Then… w-wait for us by our bed while we finish. That’s an order!”

Sombra then let go of Shining’s leash with his other hoof, and allowed the pony to drop down on his front hooves to comply. Despite how badly his legs were tensed-up and fidgeting (especially when he dropped down to his Ex’s angle, and was able to see just how far Sombra’s cock was sinking towards the back of her throat), he was able to breathe out with a strained muzzle before nodding dutifully. “Y… S-Sir, yes Sir…”

After giving a sheepish salute towards his Prince, the stallion awkwardly left the elevator while Cadance kept sucking that meaty cock without distraction. As he trotted with a limp due to his near-debilitating arousal, Shining couldn’t stop blushing when he could overhear the wet slurps of the Princess’ lips sliding up and down his shaft. He could also hear Sombra’s low and pleased-sounding groans as he embraced the exhibitionist display without any shame, and murmored deeply enough to have his voice reverberate down the hallway. “Aaaahhhhh… Th… That’s right, Cadance. Give that cock the attention you wanted…”

By the time Shining Armor finally unlocked the bedroom door and slipped inside, he nearly collapsed with a shaky moan as he tried to move past that tantalizing display he was forced to witness. He wanted to feel hurt after everything he already endured that day, but his strained chastity cage continued to ache and emphasize how badly he wanted more. Fortunately, the Guard didn’t need to look around too hard to see what Sombra left for him. In the middle of the bedroom, right beside his couch, one of the Crystal Empire Armory’s basic Guard uniforms was laid out neatly for his use. Shining bit his lip as he stared at the plain grey plating for a moment, and tried to remember how long ago it was since he wore such a lowly attire. Even though he knew he wasn’t considered a ‘Prince’ by Sombra or Cadance anymore, he honestly didn’t think he had to dress like a basic Cadet again.

Nevertheless, as he heard Sombra’s moans growing more audible past the closed bedroom doors, Shining huffed in acceptance before lighting up his horn. In less than a minute, the stallion was able to don the familiarly basic torso and hoof platings that many of his newbies were forced to wear. And unlike his regular helmet, which was made of high-quality metals and had padding on the inside for comfort, Shining’s current helmet was as basic and cheap and the rest of his armor. The moment he donned the entire getup by himself, and took a glance at his appearance through a nearby mirror, the Guard had to take a confirming breath as he realized how far he allowed himself to go.

He may have been a Prince outside the bedroom (at least, most of the time), but right now, Shining Armor felt like the lowliest Soldier awaiting his first mission.

“Aaaahhhh!! Aaaaaahhhhh!!!~ AAAAAAAHHHHHHHHHHH!!!~”

Shining’s focus went back to his current predicament as he heard Sombra’s lustful moans from out in the hallway, indicating that he just reached orgasm outside of the Guard’s line of sight. Even though it felt weird to think about it without much guilt, Shining wished that he was able to see Cadance taking that load from his Prince up-close. But alas, the Guard was able to stick to his orders after breathing out firmly, and taking his stance beside Cadance and Sombra’s bed. While a minute or two passed in silence, Shining remained in the stern and stoic stance he recalled doing for days on end back when he was a fresh recruit; except for now, he was awaiting his Royalty’s presence for a much different reason.

“Mmmnnnghhhh…” Shining could hear Sombra’s blissful groan of pleasure from the other side of the door, and was then greeted with his presence as the Prince walked in with a shit-eating grin. While he used a hoof to undo his tie and remove his jacket, he nodded with an approving smirk upon seeing Shining in his new armor. “Ah! There we go!” he said with a satisfied tone of voice. “I was hoping you could wear one of the Guards’ uniforms from my actual reign, but uhhhhh… apparently all of those were destroyed after you two reclaimed the Empire.”

Shining pursed his muzzle shut with a conflicted look, seeming unsure whether to feel grateful or disappointed that Sombra didn’t have one of those controversial relics for this night.

“However!” Sombra’s smile remained as he looked his Guard up and down with a pleased expression, and went in to give the top of that plated back a couple taps with his hoof. “I must say, you look absolutely perfect as our Official Guard, Shining Armor! You should be proud that you have such an exclusive position, despite being our Private now.”

Before Shining could respond to that statement, Sombra sighed and rolled his eyes with a shake of his head. “Oh, that’s right! I almost forgot…” He then stood in a more domineering stance above Shining, and barked, “SOLDIER! Bow for your Prince!”

Shining closed his eyes with a worried huff as he did just that, blushing hard as he bowed before his former enemy while dressed so embarrassingly basic. Meanwhile, Sombra placed his hoof on top of Shining’s shoulder and decreed, “From this moment on, Shining Armor, you are hereby demoted to the rank of Private while in the presence of myself and Princess Cadance. And yes, that includes when you’re around us outside the bedroom as well. Do I make myself clear?”

Since his head was bowed, Shining was hopeful his Prince couldn’t see the pained grimace on his face. Even with how badly bruised his ego suffered that insulting ‘demotion,’ Shining was able to breathe out shakily and reply, “I… I understand, my Prince.”

“Good!” After allowing Shining to lift himself up from the floor, Sombra left him to trot back towards the still-open doorway. The moment he poked his head out to see where his wife was, Sombra had a faux-surprised gasp before looking back at Shining with a cheeky grin. “Oh, my goodness!~” he said with a comically exaggerated look of shock, which included clasping the side of his face with a hoof. “Private, I think I have your first mission already!~”

Sombra then stepped away from the doorway, and allowed Princess Cadance to stride in with her dress slightly dissheveled. While Sombra closed and locked the door behind them, the Alicorn walked her way towards their Guard like she was planning this. The Guard’s eyes shot wide-open as he got a good look at the Princess’ face. Not because of her lustrous half-lidded gaze, or her waiting smirk as she licked her ruby-red lips. But instead, Shining’s gawked and blushed expression was due to the fact that multiple ropes of Sombra’s thick cum were draped all across Cadance's face to leave a sloppy bukkake.

Shining was frozen in shock as he watched the Alicorn trot up towards him, seeming just as antsy to test the Guard’s worth as Sombra was. Meanwhile, the Prince snickered with narrowed eyes on Shining as he said, “Private Armor! I’m needing to get hard again, so I’m ordering you to clean my wife’s face as thoroughly as you can!”

His lecherous grin then widened even more before he added, “Oh… and you need to use your tongue, Rookie~”

Shining already knew that would be necessary before Sombra even said it, but he still took a breath before gulping in confirmation. “S… Sir, yes Sir,” he muttered meekly while nodding his head. Cadance kept herself still as she stood before her Guard, but couldn’t help chuckling to herself as she saw how her former husband looked in such a nostalgic getup. Fortunately, her warm and waiting smile remained as she watched Shining close his eyes, and lean his head in with his muzzle open.

The first drag of his tongue went straight up the side of Cadance’s cheek, and Shining was instantly met with the strong and bitter flavor of Sombra’s cum. He wasn’t sure if Sombra just naturally tasted that way, or if the Prince purposely altered his diet to make his semen that strongly-flavored. It was distasteful to say the least, and his muzzle wrinkled with a strong grimace as he lapped up the first rope without much hesitation. However, even with the sound of Cadance giggling from his tongue helping to distract him, the Guard tried his hardest not to gag as he swallowed that first mouthful of the slimy substance. Meanwhile, Sombra could be heard purring in approval as he sat at the foot of the bed, and watched the demeaning act with a hoof kneading at his half-flaccid sheath.

Shining’s eyes remained clenched shut as he continued to lick up every glob of that strong-tasting cum from Cadance's face. After the first couple of laps, Shining tried not to groan apprehensively as the taste lingered badly inside of his muzzle. Cadance could see that her Private may have been struggling with his task, but remained silent with a supportive smile with each gulp Shining hesitantly took. By the time the majority of Sombra’s bukkake was licked-up with growing disdain, Shining had to pull back and try not to gag while some strings remained drizzled across Cadance's mane.

“Keep going, Private!” barked Sombra while he grinned devilishly and grasped his twitching member openly. “I expect you to swallow every drop before you take your post tonight~”

Shining nodded instinctually to his Prince’s order, but he still needed a moment to take a couple breaths and keep from retching. Despite how strongly that unpleasant flavor was building up in his mouth, Shining tried to keep himself strong for the sake of his ‘mission’. Even though he knew he couldn’t make any requests, part of him was really hopeful he could clean her of Sombra’s cum from other regions tonight too; given how that was the only form of “sex” he was able to experience, Shining wouldn’t have minded licking up more of his Prince’s thick loads for an opportunity as meager as tasting her again. But before his mind could veer off into impulsive thoughts, Cadance placed a hoof on his shoulder just as he was about to open his eyes again. When he looked back up to see the Princess’ smiling (and slightly matted) face, she gave a cute giggle before saying with a shrug, “You know, I… I think you look really good as a Private again, Shining~”

The idea of being demoted still stung a little, but Shining was able to smile back at her with a bashful blush before replying sheepishly. “Ummm… Th-Thank you, your Highness~”

“Less talking! More licking!~”

Shining sighed upon hearing Sombra’s dominant tone, and took a breath before he went back in to finish the job. He had to literally suckle down the length of Cadance's mane in individual strands, just to collect every sticky string that was matted into her hair from Sombra’s overzealous finish. He also had to re-lick a couple regions of the Princess’ face, just to collect the random strands of jizz he missed while his eyes were closed. Even though he still looked discomforted swallowing the remainder of Sombra’s cum before the couple, Shining was able to stomach the taste by the time he finished with a clean mouth.

“Therrrrreeee we go!~” cooed Sombra with a satisfied-looking grin, and his cock standing erect once more between his legs. As Shining looked back at his Prince to nod accordingly, he had to bite his lip upon seeing how brightly that shaft was still glistening from Cadance's saliva. Nevertheless, Sombra didn’t pay any notice to the Guard’s blush as he stated proudly, “Excellent work, Private! With that level of dedication, maybe you’ll work your way back up in the ranks~”

Shinings head tilted in surprise as he asked with a raised brow, “R-Really?”

“Pbbbt! No~” replied the Prince with a cocky grin as he scoffed teasingly. “Your demotion is as permanent as your cage, Private. Cadance and I both agreed it was best for you.”

When Shining glanced back towards his Ex, the mare shrugged with a blushed smile and replied, “I meeeaaannnn… It sorta does fit you now, doesn’t it?~”

Shining blushed with a reluctant expression as he looked down briefly. But despite how much his muzzle wrinkled in apprehension, he was able to think it over for a second before nodding his head. Since he wasn’t really a Prince anymore, he might as well accept himself in his new rank with the same notoriety he had as a cuckold. So after a sharp exhale, the Guard looked back up at her with a weak smile and said, “I… I guess this is more fitting of my place, isn’t it?”

While Cadance smiled back at him with a nod of her own, Sombra purposely cleared his throat so the two could look back at him. The Prince pointed to his wrist like he was wearing an invisible watch, and stared directly at his wife with a haughty grin on his fanged muzzle. “C’moooonnnnnn, Caddie… I have something new to show you~”

As soon as Sombra said that, Shining’s eyes widened with the shocking realization of what was going to happen next. It was at that moment that he finally took notice of the end-table on the bed, and saw the bottle of lubricant he bought earlier that night. Since his own stallionhood was left completely unusable, Shining knew that there was nothing he could do to stop the Prince from claiming his wife’s other hole before he could. Even with how badly he was hoping to do it himself, the Guard winced strongly to the idea of Sombra having anal with Cadance instead.

Unfortunately, the strain from his unbreakable cage was felt even stronger by the Private, which helped to keep his blushed muzzle tightly shut.

“Oh, honey?” cooed Sombra sweetly as he pulled himself towards the middle of the bed, and laid back with his cock standing straight up. “Just to clarify, you did get yourself prepped earlier tonight, correct?”

Cadance nodded her head with a lustrous smile, and crawled into the bed with Sombra while Shining stood in frozen dread. “Oh, absolutely Sombra~ After seeing how badly our Guard suffered from his first time, I wanted to be a little more prepared~”

The two giggled with knowing smirks as Cadance settled into the bed beside her husband, and nuzzled him sweetly from the side. Meanwhile, Shining had to look away with an embarrassed blush as he recalled that uncomfortable first time he experienced himself. Even though he was grateful Twilight Sparkle’s strapon didn’t tear anything during that brutal cherry-popping, the stallion cringed to himself upon remembering how long he ended up walking funny afterwards. Although in retrospect, the Guard couldn’t necessarily say he hated the experience either; not just because it helped solidify his newfound relationship with Cadance and Sombra, but also because he couldn’t deny how amazing prostate stimulation actually felt.

Nevertheless, the Guard was able to return his attention towards the couple when Cadance picked up the bottle of lube with her magic. Meanwhile, Sombra looked back at Shining with a domineering grin as he said sternly, “Private! Since it’s obvious that you’ll never have sex again… I think it’s only appropriate that you stand Guard for the two of us while we have sex from now on!~”

Shining exhaled weakly through his nostrils, and nodded while he stood in a more regal stance before the bed. Sombra smiled in approval, and added in a more formal tone, “So because of that… Private Armor, you’re being ordered to stand exactly as you are, and to remain in proper Guard position throughout our intercourse. You can not move. You can not moan. And you certainly can not orgasm, even if you were able to. Is that understood, Soldier?~”

Shining Armor breathed in before giving his Prince an obedient salute, and barked back, “Sir, yes Sir!~” He then stood upright like a living statue, and remained in that position while his face carried an emotionless stare outward.

Cadance smirked up at him with her eyes narrowing mischievously, making her look as if she wanted to test the Private’s composure right off the bat. She went back towards her husband, and grasped the base of his cock with her hoof to begin stroking the length slowly. While the Princess hummed sweetly to herself, and Sombra laid back with a blissful sigh upon feeling her loving touch, Cadance’s smile returned towards Shining’s gaze without pausing her movements.

“Mnnnghhh… I hope you have a good look, Shiny~” she said condescendingly, which was then followed by a giggle when she saw how stoic the Guard’s composure remained. She then upped the ante as she bent her head down close to that plump cockhead, and added in a more ruthless tone, “Because I can promise you one thing… your cock will never get this kind of attention from me anymore~”

Shining remained firmly in place, but the Alicorn noted the slightest twitch of his left eye upon hearing her say that truthfully cruel remark. Unfortunately, Cadance was only starting as she then turned herself around, and got her backside pointed towards the blushing Guard. While Shining tried to keep his expression unbroken, the Princess bent herself over to lift up her tail and expose her glistening marehood. Even though the sight of that winking, glistening pussy was beyond enticing for the locked-up Private, he was somehow able to keep himself from whimpering audibly to the long sought-after sight.

“Mnnnnghhh… You like seeing that, Soldier?~” she asked while looking back at Shining with a sultry grin, making sure to give her plump backside a teasing wiggle. Despite his lowered status before the Royal Couple, Shining Armor was showing some impressive levels of self-control while he remained standing still, and kept his expression set like stone. Even Sombra couldn’t help looking the Guard up and down with a slight glimmer of respect for his diligence, even though his muzzle was still smirking wide while chuckling to the sight. Meanwhile, Cadance kept swaying her hips to try and break her Ex’s composure, making sure that her marehood was spread open invitingly wide to let her wetness show. “Ahhhh… I bet you wanna mount me right now, don’t you?~”

Sombra wanted to keep their Guard in place for the duration of their evening, but the idea of adding a little more humiliation prompted him to speak up. “Private Armor!” he belted in a commanding tone as he took that bottle of lubricant from Cadance, and uncapped it to begin pouring over his waiting cock. While the Princess kept showing off her untouched pussy towards her immobile cuckold, her hoof began to stroke more of Sombra’s length to help coat every inch in that much-needed lube. Meanwhile, Sombra smirked curiously as he said towards his soldier, “I’m giving you permission to answer to your Princess, Shining.”

That response seemed very well-appreciated, since Shining let out a deep and shaky exhale the instant Sombra said it. Nevertheless, the Guard still kept himself still as he glanced down at Cadance’s waiting and alluring stance, and took a breath to keep from speaking too hoarsely. “I-I, uhhh… Yes… Yes I do, Princess Cadance…”

The Alicorn peered up at him with a wider grin as she giggled to Shining’s sheepish response. While her hoof continued to slide up and down Sombra’s waiting shaft, causing the Prince to groan and shiver in delight from her experienced form, Cadance brought her other hoof back to teasingly rub along the supple outer-lips of her glistening cunny. She hummed sweetly while she played with herself, making sure that her Guard got a good look at her wet hoof toying around a little with her throbbing clit. The entire spectacle was likely extremely difficult for Shining to endure, but he was able to stand still and watch in a statuesque manner; of course, the Alicorn was able to pick up a couple faint metallic clinks, which could could only assume were drops of the Guard’s precum dripping inside of his armor..

“Hehehehehe… Do you really think you could get that tiny thing inside me now?~” she asked in a mean-spirited, but still coaxingly sweet tone behind her alluring smile. “Nnnnfffff… I… I bet I wouldn’t even feel it anymore~”

Shining’s eyes struggled to stay open while he exhaled sharply through his nostrils, and bit his tongue to remain in a sound stance as Guard. Sombra’s eyes narrowed on him as he grinned immensely, making it look like he just thought of a wickedly fun “reward” for the locked stallion. Even though he didn’t want Shining to break his previous orders so soon, the Prince seemed rather intrigued as he asked him, “Oh, Private? I believe my wife asked you a question, did she not?~”

Another strained breath came out through the Guard’s gritted teeth, and he almost broke his stolidity as he reopened his muzzle to answer accordingly. His eyes couldn’t stop darting between his Prince’s lustfully menacing gaze, and the cruelly sensual sight of Cadance rubbing her pussy in wait. “Ummm… I… I’m not sure if I’m able to, y… Y-Your Highness…”

“Hmmmm…” Sombra’s smirk intensified while staring at his stoic and blushing Guard, and he grew curious enough to ponder that answer himself. After giving Cadance a light tap on the shoulder to pause her efforts, she waited for her to look back towards him before asking, “Honey? Considering how complacent our Guard has been acting… would it be alright to allow him to try?~”

Shining’s eyes widened in shock, which was luckily the only visible movement the Guard could be seen making in response to that request. Fortunately, the couple were staring at one-another as Cadance raised a brow in intrigue, and grinned devilishly with a shrug. “Weeellllllll… I doubt he’ll be that useful in the state he’s in now,” she stated in a honest tone, making herself audible enough to make sure he heard that. “Buuuuttttt… I suppose it wouldn’t hurt to humor the Private a little~”

The instant Cadance looked back at Shining with a welcomely wide and saccharine smile, Shining’s nostrils flared out while he breathed in sharply to such a surprising turn of events. It was at that moment that the Princess bent herself down into a presented stance, and gave him a better view of her pristine and drooling marehood. Sombra cleared his throat to gather Shining’s attention, and leaned back with his hooves behind his head while commanding, “Private! I’m giving you permission to come into our bed, and attempt to mount Princess Cadance for my entertainment! If she can’t feel anything in a span of… oh, two minutes, I suppose?~ Then you shall pull yourself back off, and return to your earlier duties like before. Do you understand?~”

Shining was already shaking in anticipation as he eagerly nodded his head, and gave a quick salute to his Prince. “Sir, yes Sir!~” He then hopped himself into the bed, and almost fell over due to the jarring softness he hadn’t felt in so long. Even though he wanted to lie down and appreciate the mattress he missed rather badly, the waiting prize of Cadance’s presented form took paramount in the Guard’s antsy mind.

The instant Shining got himself braced on top of his Ex’s back, Cadance jolted from the quickness of his actions. “Oooh!~” she said with a surprised smile and a giggle. “I guess you want to prove yourself, huh?~”

“Y-Yes, my Princess!” blurted Shining as he got into a proper stance atop the Princess’ back, and tried to ignore Sombra’s studious stare on him. The Private tried to move his hips inward to make contact with her voluptuous backside, but couldn’t help groaning briefly in frustration due to his cock straining painfully in its confines. The smooth, petite plastic of Shining’s chastity cage pressed weakly against the outer lips of Cadance’s pussy, but she ended up shivering more from the long-forgotten feeling of his weight on her back again. Considering how long it’s been since he actually got this sort of opportunity again, the Guard tried not to think too hard about how jarring the experience as a whole must’ve felt for either of them.

The stallion’s muzzle was skewed in a mixture of nervousness and discomfort, but he tried his hardest to actually penetrate between Cadance’s glistening lips with the head of his cage. Unfortunately, the Princess’ unaudible squirms from beneath him made it clear that his efforts were fairly unappreciated by her. Shining grunted with his lips pursed shut as he tried to move his hips in even tighter, but the added contact proved to be worthless when it came to getting inside of her. Instead of feeling himself slipping between those smooth and velvety lips to make her moan like he once had, all that Shining could feel was the painfully titillating pressure of his cage binding his member tightly, and keeping him from even feeling semi-erect; not to mention, the only response he heard from Cadance was a faint, but still unsatisfied-sounding huff.

Despite his growing desire to actually get himself inside of her again, the Private struggled to make himself useful while his cage awkwardly pressed against those closed lips without any penetration. Meanwhile, Sombra just openly cackled at his Guard when he saw how strongly contorted his look of frustration was getting. While one foreleg remained behind his head for comfort, his other went down to stroke his lubed cock by himself. “Ohhhhh, goodness!~” he jeered with an amused grin while he shook his head. “If only you could see yourself right now, you worthless little freak. Do you even realize how pathetic you look right now?~”

Shining had to close his eyes to try and focus on his efforts, even though he was unsure how much time he had left. In a last-minute attempt to give himself some form of relief, his hips began to move back and forth against Cadance’s backside to give a measly attempt at something close to “thrusting”. Even if he was just pressing his casing against the Princess’ unusable cunny, the added sensation against his cage was just enough to make the Guard bite his lip and groan with an enamored blush. He was sure that he was failing immensely, and likely not giving Cadance much pleasure at all from her end; however, considering how this was the closest he’d come to having sex in months, Shining tried his hardest to appreciate the moment as he continued pumping his hips, and muttered shakily, “I… I-I’m aware how this may look, m-my Prince. Bu… B-But I’m trying…”

“Psh~ Barely,” Sombra retorted with a mocking scoff. He looked down at his wife, whose amused blush did very little to conceal the disinterested expression on her face. Even though she was smiling a little in appreciation of the Guard’s efforts, Sombra could tell she was mostly waiting for his two minutes to be up. “Honey, are you feeling anything at all from his efforts?~”

Despite the soft and involuntary groan that escaped her muzzle while the Guard kept pressing against her sensitive marehood, Cadance shook her head as she smirked up at him and said audibly, “Ar… Are you kidding me?~ I… I almost want to laugh at how bad he is!” As soon as she heard Shining huff out a pained groan from hearing that, Cadance snickered mischievously while letting him keep going for another moment. “H-Honestly, it’s like he’s… like he’s playing pool with a rope back there!~”

Sombra reeled his head back as he cracked up from that quip, completely ignoring Shining’s hurt expression. But regardless of Cadance’s mean remark, Shining tried his hardest to enjoy the experience while he thrusted against her and pursed his muzzle shut. Even though this could barely be considered “sex” by even the most prudish ponies, Shining was able to appreciate the moment long enough to moan a little from the constant presses of his cage against his locked cock.

“Oh my Goddess, are you actually enjoying that?!” gawked Sombra as he stared at him with a look of amusement and disgust. Cadance heard her Guard’s moan clearly enough to giggle a little as well, which only intensified the shameful pleasures Shining could experience in that moment. Unfortunately, his attempt to pleasure Cadance himself was cut short when Sombra got up from his spot, and pushed the Guard off of her with his hoof. “Okay, your moment is over, you little weirdo! Get back in position, and that’s an ORDER!”

Even though Shining shivered painfully from that abrupt interruption of his very limited pleasure, he was able to sigh in defeat and nod his head meekly. Unfortunately, the Private’s hind-legs couldn’t stop trembling from his pent-up strain as he tried to stand upright, which caused his leg-platings to shuffle and clack a little. But while Shining struggled to keep himself still and regain his stoic stance for the remainder of his duties, Sombra kept his focus on Cadance as he sat himself down in front of her still-presented position. As the Prince sat with his superior cock still coated in lubricant, he reached out for that bottle to uncap it once more for his wife. “Alllllllllright, my lovely mare… Now it’s time to feel a real cock inside of you again~”

Shining silently gulped as he finally got himself to stand still again, even though he had no idea how long that could last. Since he wasn’t allowed to move, he couldn’t remove that pesky ring Twilight gave him before Sombra could begin. And given how badly that “bracelet” vibrated every time Sombra was inside of her, he could only imagine how intense the session was going to feel when it came to anal. But alas, despite his growing worries that risked his composure to break into a pained wince, the Private stood silently while he continued to leak inside of his armor, and watched Sombra pour a generous drizzle of that clear fluid over Cadance’s exposed tailhole.

“Aaaahhhh~” Cadance bit her lip with a tantalized shiver as she felt that cold lube coating her waiting entrance, which was already puckering a little for her husband. Even though the Princess made sure to have herself prepped for that night, even the Guard could tell from his angle that she was going to be an incredibly tight fit. Nevertheless, Sombra made sure his application was slow and nurturing as he rubbed that wrinkled ring of flesh with his hoof, and massaged the oils around every inch for added assistance. The Princess moaned from feeling his touch again, clearly preferring it over that laughable display Shining tried earlier. “Mnnnghhh… You… You don’t have to hold back now, honey~”

“Well, I don’t want to hurt you either,” stated Sombra with a warm and reassuring smile towards her. “Especially when you’re carrying my foal now.”

Cadance seemed like she wanted to retort due to her eagerness, but pertly sighed and shrugged after that last detail was said. Fortunately, Sombra only needed another moment before he gave a satisfied smile, and capped the bottle to place nearby. While Shining watched the two with a blushed and statuesque expression, Sombra grabbed the mare’s plump cheeks tightly with both hooves before guiding her back. It was at that moment that Shining realized his Prince wasn't going to mount her like he had attempted. Instead, Sombra was going to have Cadance ride his cock in front of Shining, just to add another notch to the list of things she never did with him.

Despite her pregnancy, Cadance was still agile enough to lift herself up and hover over that dauntingly thick cock Sombra possessed. From Shining’s angle, he got a perfect view of the action as her glistening tailhole slowly lowered closer towards Sombra’s waiting and crowned cockhead. He may have seen that superior stallionhood penetrate her countless times in the past (and even assisted a few times for added humiliation), but he still tried not to shiver in envious pleasure as that plump head pressed against her puckering hole. The Alicorn breathed out with a soft and strained groan, and needed a second to brace herself while her eyes were clenched shut.

“Okay… Okay, I think I’m good…” While Cadance muttered to herself in prepatation, Sombra sat silently with a patient smile as he rubbed her flanks softly. The sight made Shining bite the inside of his cheeks again, silently wishing to himself that he had the chance to have such an opportunity before it was taken from him. But alas, the Guard knew it was probably better for him to watch nowadays, since Sombra would be able to ensure she’d experience it properly. So instead of remaining jealous while standing still, Shining tried to remain supportive as he heard her begin to groan even louder.

“Mmmmnnnnnnggggggggg…” The Princess began to lower herself on top of Sombra’s cock, hoping to use her weight to help assist in the painful process. However, Cadance still carried a sharp grimace on her face as she winced from the added pressure, and felt her tailhole trying to open up. Shining was able to see that one of the sides of Sombra’s cockhead had to slip past that opening first, just to help open her up enough to cram in the rest of his meaty girth. Even though the sight of such a tantalizing thing made his chastity cage continue to strain, the sounds of Cadance’s high-pitched groans made him struggle not to wince sympathetically.

Fortunately for both of the stallions involved, Cadance didn’t try to relent as she kept pushing down, which allowed more of that plump head to sink past her ring and stretch it out even more. Even though Sombra was holding her securely with a trusting stance, he was able to smile proudly as he saw her trying to take him with diligence. “Thaaaaaaattt’s right,” he said with a soft and assuring whisper. “You can do it, Cadance. I believe in you…”

Shining wanted to voice his support as well, but remained still as to obey his Prince’s orders. Fortunately, it seemed that Sombra’s words were just enough to make Cadance keep going. Even when she let out a pained yelp during her strenuous pushing, the Alicorn could be seen giving it her all as her strained face grew a heavy shade of red. And with an especially heavy groan from the back of her throat, Cadance cried out in a mix of overwhelming pressure and relief the instant his cockhead slipped inside with an audible pop. “GNNNNGHHH!!~”

Shining’s face clenched in as he hissed as hard and as silently as he possibly could. Fortunately, all that Sombra could overhear was the heavy buzzing that ring around the Guard’s cage made while vibrating. The Private had to bite his lips tightly together to keep from groaning in pained pleasure, but it almost felt like torture when that vibrating refused to let up. Meanwhile, Cadance made sure that thick cock was buried inside of her the entire time her Ex was left fidgeting in his titillating torment.

“GNNNAAAHHHHH!!~ Mmmmmmmm… Nnnnnnnffffffff~” Cadance paused her efforts while she was awkwardly squatted on top of Sombra’s shaft, with his head firmly inside of her to leave her hind-legs shivering. Shining’s lips pursed tightly shut as he blushed to the sight of her outstretched tailhole, which was wrapped tightly around Sombra’s girth to emphasize just how inexperienced she may have been. But despite knowing from personal experience how painful that could be, the Guard didn’t say anything while shivering from his tenacious ring, and hearing her shudder with a hoarse and eager moan.

“Aaaaaahhhh… I… I’m soooooo glad I had you for this~” she said with a weak and shaky tone, which Shining could tell was undoubtedly genuine. Meanwhile, Sombra hissed in pleasure as he quivered from the Alicorn’s near-painful tightness around his cock, but still grinned with an approving nod.

“Believe me, my Princess,” purred Sombra in a slightly strained tone while his hooves petted her flanks tenderly. “I’m grateful to give you this first experience as well~”

Shining tried his hardest not to wince from that truthful remark, even though it reminded him of how long he spent wanting to ask her for that chance during their marriage. But with that opportunity gone for good, Shining was left feeling complacently hopeless and on-edge while he was left standing Guard for her and her new mate. And as the seconds passed with both of those ponies breathing heavily and groaning in pleasure from one-another, the Private was left to stew in his own guilty arousal while his cock was untouched but endlessly teased by that damn ring.

“Aaaaahhhh!!~” Cadance was able to adjust to the stretching faster than expected, and soon allowed herself to lower her body even more against Sombra’s cock. Shining could see inch after inch of that meaty shaft slowly disappear from view, while Cadance’s tailhole remained stretched tightly around it to leave the Prince groaning with a pleased smile on his face. Despite how blushed and strained the Alicorn may have appeared from Shining’s angle, her breaths came out in increasingly pleasured moans as she let more of her husband’s cock fill her in such an unfamiliar region. Her Ex may have had no idea how much she was able to actually take, but he knew he was going to be left writhing as long as his bracelet kept buzzing around his swollen blue-balls.

The Princess’ moans deepened as the seconds passed with Sombra inside of her, much to Shining Armor’s torturous pleasure. As she got herself more accustomed to that monstrous cock burying itself inside of her, she never once pulled out to give their Guard even the slightest semblance of relief. Instead, Shining was left to grit his teeth in undying tantalization throughout the ordeal, and continue to drip copious amount of pre in his metal plating. Eventually, the poor stallion was left to stand shakily while tears began to bead at the corners of his eyes, despite knowing that could easily break his Prince’s orders. Fortunately, Sombra paid absolutely no notice to the tortured Guard while Cadance began to slide herself back up his veiny length.

Shining had no idea if Cadance was going to slow because it was her first time, or because she knew it would leave him clinging to the edge with no possible means of personal release. But regardless of the reason, the Princess took her sweet time as she slid herself up to that plump cockhead, while her tailhole remained firmly wrapped around Sombra’s girth. Then without warning, the Alicorn pushed herself back down at a surprisingly quick rate to elicit a heavy moan. Of course, Shining ended up wincing with a heavy whimper at that exact same time, since that action caused his vibrating ring to pulsate strongly around his cage.

Cadance repeated her motions at an slow and steady rate of speed, which Shining wasn’t sure was a good or a bad thing. Even though his strained and dripping cage was going to be left locked and untouched nonetheless, the added pulses of that ring that came with her tenuous slides across Sombra’s shaft were leaving him endlessly riled-up. The Guard’s balls were swelling from the growing titillation as they dangled behind his muzzing cage, and were sporting a heavier shade of blue with each minute spent in that torturous ordeal. Even though the sounds of Cadance’s hefty moans kept him at bay as she got herself into a pleasurable rhythm, Shining wasn’t sure how much more he could take before he collapsed from the overwhelming strain of chastity.

And even worse… Shining wasn’t sure if he actually had it in him to make it stop.

“Aaaaaaaahhhhh!!~” Sombra reeled back as he gripped both of her flanks tightly, and moaned with each sensual motion of her tight hole sliding up and down his throbbing shaft to bring him closer to release. By the time Shining was left involuntarily squirming in his clanky armor, Cadance was growing just as enticed as she openly moaned and embraced her first time taking it from behind. Her groans were still notably strained due to the lingering pain she felt, but her desire to continue overrode any discomfort as she hopped up and down that cock at a faster rate. While Shining was left fidgeting with his face tightly clenched shut, his ears twitched as he heard his Prince moan out, “Aaaahhhh!! Sh… Shining! You… You could’ve had her allllll to yourself! Thi… This could’ve been YOU! B-But now, you… you have NOTHING! H… How does that feel, huh?!~”

Shining couldn’t stop writhing in his restraints while he stood in his armor and tried not to buckle from the strain. Unfortunately, the pain he was feeling from that ring combined terribly well with Sombra’s truthful words. He really did have everything before his Prince came along, and made him give it all up for Cadance’s pleasures. He used to be a Prince with a loving wife, with more than enough respect and confidence to savor the life of luxury he possessed. But now... he was left a divorced Private who was forced to endure his former enemy fucking his beloved in front of him, just after knocking her up and ruining his chances of ever getting hard again. The overwhelming reality of that change hit the Guard like a brick to the face, and he was left blushing hotly while he moaned painfully in his frozen state.

“Mnnnghhh… You… You better answer me, Private!” barked Sombra as he grew closer to completion, and gripped Cadance even harder to rut that ass relentlessly. “How… Does… That… FEEL!?!~”

“AAAHHH!!~” Shining let out a pained cry of pleasure as he stared at Cadance taking that massive cock in front of him, and fidgeted each time his ring pulsated around his cage. “It… It feels…”

The precum that was pooling inside of his armor finally began to dribble out near the back, and made it look like he was wetting himself from his admission. Shining’s eyes clenched shut, but that was all he could do before he bellowed out, “I-IT FEELS AMAZING, MY PRINCE!!~”

“THAT’S!! BUCKING!!! RIIIIIIIGHT!!!~” With that last heavy exclamation, Sombra pulled Cadance down as he thrusted deep inside of her. The Prince practically roared as his strenuous cry echoed within the bedroom, and left the Princess reeling in absolute pleasure from his cock unloading inside of her. Her fur stood on end for Shining to witness as hefty spurts of Sombra’s cum flooded her insides, shooting as far back as it could reach to fill every inch with his thick and fertile seed. And due to how tightly Cadance’s hole was clasped around his member, Shining wasn’t given any relief himself as his cage continued to vibrate intensely, his eyes were deprived of the sight of just how much Sombra came inside of her.

The couple were left moaning in tandem as both of them reached their climaxes in front of their Guard, clearly loving every second that passed within each other’s passionate embrace. Despite how winded both of them became after that strenuous session, Sombra and Cadance shared a long and lingering kiss while their bodies rocked from the aftershocks of their shared orgasms. By the time Sombra was finished unloading into her, the Princess fell forward into the bed in a half-comatose stupor. Of course, considering how the Alicorn just spent several minutes doing most of the physical work, Sombra wasn’t the least bit surprised that the filling left her completely exhausted.

Shining had no idea how he hadn’t collapsed on the floor, or somehow orgasmed himself due to how pent-up he was getting from what he just endured. But against all odds, the Private was somehow able to keep himself standing by the time the Royal couple both succumbed to the long and lingering lengths of their orgasms. He could hear how tremulously Cadance cried midway through Sombra’s climax, and could smell her arousal while she squirted a hefty amount all over their bed. As for their poor Private, the stallion was leaving a considerable puddle of his own while precum was dripping at a steady rate from his aching cage; even though most of it was still within the underside of his armor, Shining could hear it dripping out from the back by the time the two were finished in front of him.

Shining wasn’t sure how long he was kept in that incessant buzzing state while Sombra was buried inside of her, but the sensation stopped quickly enough to make the Guard gasp and shiver relentlessly from the much-needed relief. Unfortunately, Sombra only had his flaccid member pulled out for a second or two, before he grabbed a nearby plug that was on the end table. “Mnnnghh… Just so you know,” purred the Prince tiredly as he reached back towards his wife, and slipped the plug inside of her hole to avoid more leakage. “Be sure to inform me of any other fantasies you had regarding you and Cadance, will you?~”

Shining was unbelievably tense and writhing on the edge as he kept fidgeting in his leaking armor, unable to stay still after that torturous ring turned on again. But even while he was left squirming in torment, Sombra just smiled at him evilly and said, “Just remember, Private… if you remain a good little cuck for us, then we might let you watch us act out some of them~”

While the Princess hummed tiredly and shivered from the welcome fullness, Sombra fell back onto her embrace as they laid together in the plush bedding. Neither of them seemed to care about Shining as he was thrown right back into his endless edging, despite the small puddle of pre that was growing between his hind-legs. Instead, Cadance just turned off the lights with her magic, and succumbed to a much-deserved rest while Shining’s ring was left buzzing without mercy. “Mnnnghhh… G-Good night, Private~”

With that, Shining was left standing completely alone in the dark while his body was torturously left in such a painful high. And even as the couple fell to sleep, with Sombra snoring loudly as he nuzzled the back of Cadance’s neck, Shining’s ring could still be heard buzzing within his bulky and shaking armor.

While Shining Armor stood with a wide-eyed and pained grimace throughout most of the night, he wasn’t sure how in Equestria he could last by the time morning came. Unfortunately, the Guard also didn’t seem to care either, since the experience as a whole left him silently desperate for more.
