With every loud flap of the guards’ powerful wings, Dusk could feel them getting further and further away from where they needed to be, and the unfamiliar feeling of the cold high air flowing gently over and through his thin fur reminded him of the endless night that awaited him if he- not Celestia- failed.

Thinking of coldness and fur made Dusk look down to his little brother, who he hoped had come to share in his anxiety for once, but only saw the young dragon staring straight forward in the chariot with an even smile, as if he was somehow excited by the prospect of organizing a celebration in backwater town most of Canterlot didn’t know the name of.

Spike apparently noticed his brother’s melancholy frown out of the corner of his eye though, and adopted a similar expression as he looked to him.

“C’mon Dusk,” he said in his signature pleading, encouraging-negligence-of-duty tone. “You, Celestia and I could be smack-dab in the middle of the Badlands and still make any thousand year-old demon wish it’d stayed on the moon.”

“Celestia will be preparing for a public appearance in a town without access to most of her tactical assets, Spike.” Dusk reminded. The purple unicorn then sighed and leaned over the front of the chariot. “And we’ll have nothing but a tiny library to work with and a celebration to organize first nevertheless!” He suddenly straightened up, holding up his finger in a gesture of profound exclamation. “As Celestia’s most faithful student and subject, I will neglect neither my duties to her, nor Equestria. As I said before, we’ll plan the party in record time, and then bring the elements to bear and defeat Nightmare Moon with no undo civilian endangerment.

Spike thought for a moment he heard a pair of snickers in the wind, but his brother was busy taking a smiling look at the first stage of their assignment in Ponyville in the distance, only to realize that it wasn’t approaching as fast as it had been. The wind had died down and the angle they were seeing it at was also changing, because, it was clear, the guards were bringing them down to land already, most likely in an upcoming field in a small forest. Spike saw his brother’s tense face as he realized the time they were losing and tried to speak calmly for him

“What’s wrong?” Spike asked. “You feel like you’re pulling something broken?”

Evidently not, as they continued to gently descend to the clearly of unkempt grass, and after the slight jolt of the landing, they rolled fairly smoothly over the ground to a stop.

Dusk grunted from the stop in the chariot, then looked forward at their escort, who were casually unstrapping their harnesses.

“We don’t have time for-” he paused, then scrunched his eyes closed briefly in frustration. Shining, did you pick the worst day possible for one of your guard-pranks?

In complete silence and uniform, the two muscular stallions turned around and walked around their respective sides of the chariot, but contrary to their legendary composure, they were both smiling knowingly to each other. Dusk saw Spike smile too, apparently having come to the same conclusion he had- at least in the intellectual sense. A frown now firmly on his handsome face, Dusk stepped down off the chariot onto the soft, tall grass to try to talk the the guards now some ways behind the chariot.

“Um… Greyblade, isn’t it?

“It’s Nightwing actually, and my partner’s Knightlight,” the guard corrected, casually opening one of his belt pouches.

“Well I’m sorry. I’m sure my brother said my reaction would be priceless, but you have to know that not only was I assigned this mission by Princess Celestia-”

“Hey! What’s that for?!” Dusk heard Spike cry out, and nearly snapped his own neck as he twisted it around to check on his brother.

At the exact same moment he he saw and heard Spike cry out as a syringe of clear liquid was jabbed under his neck scales he felt a deep, painful prick in his left asscheck through his jeans. For a split second Dusk was confused and thought what the pain he was feeling was just empathy, but when Spike proved much quicker than his older brother and swiped a small claw across the guard’s face that he was able to reach thanks to the added height of the chariot, Dusk sprung into action as well.

The purple stallion blinked his eyes, and within that time frame a blast of transparent purple shot out in every direction from his horn. He felt the relief of the needle leaving his body as quickly as it had pierced him, and the stallion who held it was blasted away too.

Dusk opened his eyes, and covered his gouged ass with his left hand, but when he looked forwards to where he had felt the pegasi guard land through his magic, he saw some po- No, that wasn’t a pony. It was male-equine in shape obviously, but its skin and fur seemed to blend together even better than a pony’s due to the total darkness they shared, and outstretched on either side of the dark-purple armor clad figure were the wings of a giant bat.

And when Dusk Shine spotted the slit-eye symbol on the guard’s breastplate, his fears of the situation were confirmed.

“You’re with Nightmare Moon!” He pointed at the bat-pony on the ground, who was quickly recovering from the unfocused concussive blast and sitting up, smiling.

“*Grunt* *Hack!*” Dusk heard Spike behind him and spun his body around to see that despite the little dragon’s apparent alertness, he was now off the chariot and held off the ground by the- well, now the other guard was a bat-pony too. They were clearly using some kind of basic illusion spell that broke down under minimal damage, but it didn't matter. Shining and Celestia had seen them off into a tailored trap that had just sprung, and now they were alone, injected with Celestia-knows what, and half hostage. A cold shiver ripped through Dusk’s entire body as the situation became clear to him, but he clenched his fists and fought back the drive to panic. The moment he had read that entry in “Predictions and Prophecies” he’d known that the coming days could go this way. He was trained by the captain of the royal guard and Celestia, and this wasn’t Nightmare Moon; this was just two of her few loyal soldiers. He quickly analyzed the situation and considered course of action, just like choosing a spell for an open-ended test.

He could probably still teleport, but he couldn’t just leave Spike, and there was no guarantee he’d have the stamina to make it to Ponyville quicker than bat-ponies, especially with the probable toxin soon to take effect. Their best bet was probably to at least take out the immediate threats fast as soon as Spike was free.

“Nightwing’s gonna put a limiter on your horn and cuffs on your wrists,” the bat-pony holding Spike against his breastplate, Knightlight stated, squeezing the little dragon’s neck a little tighter, causing him to hack up small curls of flame. “And if I see even a glint of light coming from your horn, your little pet gets to see his own ass.”

That’s right. Dusk’s eyed narrowed on the dark being’s arms as he choked Spike. Keep thinking you’re in total control. Keep focusing on me. C’mon Spike; you can do this. You can bite- Whoa!

Dusk’s thinking was interrupted by his knees buckling beneath him. Stumbling and rebalancing himself only made him realize how stiff and weak he was actually feeling. The burning of flowing blood under his fur was gone, as was his heightened awareness and strength. His legs were losing all their muscle, and when he looked down briefly, the grass looked like a comfy place to fall. He looked up incredulously at the soldier holding Spike, who had a broad smile. It didn’t take Starswirl the Bearded to tell what was responsible for this sudden feeling of not exhaustion, but physical weakness.

“We-” Dusk tried to speak bravely as the situation worsened by the second. “We won’t be any leverage against Celestia! Our lives are a small price to pay for- uuh!”

Dusk saw Spike’s eyes widen just a moment before a metal-tipped boot crashed into the back of his right knee. There was no sound of crunching or great pain, but he was hit in just the right spot to destroy any hope of keeping his leg straight. His balance gone, he simply flopped forwards onto the grass, which along with his arms, broke his fall, but his previous hypothesis was still proven wrong because he wasn’t remotely comfortable having fallen the ground.

He tried to spread his arms out and push himself up, but his arms felt like they’d been through an intense workout and simply refused to raise him more than an inch. The guards laughed as he kept pushing though.

“That’s it candy ass!” Nightwing taunted as he knelt down behind Dusk’s feet. “The Queen don’t take boys without serious stamina!”

“Nnnn! Celestia… has the… elements. There’s nothing we can… tell you- guuh!”

Dusk finally slumped to the grass. They’d failed. They were coming with these servants of the night. They were leaving this bright, calming field and going to some dark dungeon to possibly meet Nightmare Moon, possibly never see Celestia or Shining or their parents again, and possibly meet agonizing deaths. Dusk wanted to tell Spike to relax and give up for the time being like he had, but he didn’t have the courage to vocalize his defeat.

From his left where Nightwing knelt down, dark, thin-furred hands that were resultantly warm-to-the-touch grabbed Dusk Shine’s wrists and easily pulled his limp arms behind his back to begin fastening a pair of handcuffs around them.

You don’t-uuh!” Spike leveled his heavy claw at Nightwing and tried to talk back, only to be dropped onto the grass like a sack of apples.

“Spike!” Dusk “shouted” as loud as he could, hopeless and lungs without the strength to push against the ground.

“Your little pet’ll be fine,” the second guard said as he walked over the completely limp dragon and towards his comrade. “We’re not sure how we’ll use him though; too small to be dangerous, or sexy.”

Nightwing’s warm hand steadied the back of the unicorn’s head, and Dusk closed his eyes and held his breath in anticipation without even realizing it. A thin but tall metal ring, roughly an inch in diameter, was quickly slid over his horn and forced down his widening length until it scraped uncomfortably for a second and stopped when its bottom touched his scalp. The tight handcuffs were the only thing actually hurting him, but Dusk still winced at the sealing of the limiter which he’d come to associate with the pain of trying magic with one on. It always feels like your horn’s clogged up and ready to burst open, and all the workouts and training with Shining and Celestia didn’t make Dusk feel any less like a weak earth pony now.

“There. Won’t be needing that anymore,” Nightwing said, satisfied.

Dusk kept his eyes shut and slumped his face in the grass. The sun may have seen been in the sky and Celestia presumably safe, but he and Spike had just failed her and the kingdom they all loved in their time of need. The most powerful unicorn in Equestria had just let himself and his brother be effortlessly subdued. Now at best -if Celestia did come to realize what the prophecy said and launched a full campaign against the dark alicorn using the Elements- the two of them would be hostages undeniably benefitting the enemy. At worst: eternal night and when he met Nightmare moon she’d-

“Gag him already and let’s go.” the other guard said, but not in a concerned or malicious tone.

“Oh c’mon Knightlight,” Nightwing pleaded. “We’re making sexy history here! We should savor this moment.”

“Do you mean history that is sexy?” Dusk couldn’t help himself squeaking out a question.

Nightwing didn’t falter. “History of sexy, sexy. But I think my partner may have had a point.”

Dusk was still confused, but then something was picked up off the ground to Dusk’s right, and then swung in front of his head. And of course, curious stallion that he was, he just had to raise his head up slightly to look at the red rubber ball, allowing it to be yanked backwards by its straps and pulled between his teeth. Although he slumped in the grass again once its buckle was clipped, Dusk yelled once and jerked his head up as the rubber ball fit into his mouth snugly and was secured tightly around his upper neck, not because an aching jaw and the taste of rubber in his mouth was unfamiliar, rather the opposite: he knew just how helpless he was now without even a voice to talk back or call for help.

“There we go,” Knightlight affirmed his partner’s handiwork, standing in front of the trussed-up unicorn with his hands on his armored hips. “Comfy now, little bondage slut?”

Dusk winced and whinnied as Nightwing pinched his right asscheek tight through his jeans.

“Of course he is. He’s been the sun-slut’s bitch since he had the confidence to ask a mare, and now he’s on his way to get himself a real mistress!”

Dusk’s eyes went wide again, and he felt strange in his privates. Up until now he’d assumed the bat-ponies’ comments had been sarcastic taunts, but what if they were being serious? If Nightmare Moon was the opposite of Celestia, could she…? would she…?

Even though his neck itself was stiff by now, he looked up at Spike’s crumpled purple form again. The two of them were the only ones who’d mentioned torture or hostaging so far: all the two Nights had alluded to were things pertaining to sex, and the small, not-yet attractive dragon had been mostly an afterthought in such discussions.

Does Nightmare Moon want my… body? His blood ran cold and eyes fogged as true despair and fear gripped his heart. Have the highly exaggerated rumors the castle staff spread about my physical attributes and sexual prowess really reached the moon? Is this how the night demon plans to humiliate and demoralize Celestia; by raping her student and coltfriend?

His eyes focused on Spike again.

“Huh-hease-,” he tried to plead with only his failing tongue that was forced to lap over the intruding rubber ball. He’d no doubt been poisoned with Carboxylic-magnacane; even if he wasn’t feeling tired, he’d be unconscious soon. “Huh-Heve him heeee-”

His tongue couldn’t stay moving, and his deliberate, deep breathing was wearing him out. His unaffected subconscious would keep him alive through shallow breaths the moment his world went dark, which he knew was inevitable, but he still couldn’t bear the idea of-

The feeling of his medium-sized horn being sucked by a large mouth- every one of its millions of nipple-sensitive nerves feeling gently stimulated as if they were performing magic but without the pain of concentration- was how all of Dusk Shine’s best days started.

He was- no, they were in Celestia’s bedroom. Dusk’s alicorn marefriend was underneath the silk covers, unmoving aside from her gentle hornjob, but the unicorn himself was above them, naked, and tied so that his arms were bent in on themselves behind his back and his legs couldn’t be separated. It was dark, but because the unicorn felt the familiar stiffness from being bound for a night, his crotch was stained with dozens of rounds of juices, and the princess of the sun was late for nopony’s cock, it wouldn’t be for long. He turned his neck to his right, and because his horn was still being sucked and his sore rod forming yet another erection, he caught an eyeful of Celestia’s perfectly rounded, large-but-not-comedically-so mammaries, which made him think of after the sun was in the sky.

Maybe she’ll take me a few more times before we go to breakfast and I’ll get to show her some of my new food spells. Or maybe she’ll just leave me here for the guards and maids again. Of course, I still have to-

He paused as he tried to remember what he had to do today. He tried to look up, and wished that she’d stop sucking for a second so he could concentrate, but her mouth was getting drier, and the air around him colder until he didn’t feel like he was on a bed at all. Then he remembered what he needed to do today by remembering what had happened yesterday, if a day had indeed passed.

Dream-like hallucinations as the brain slowly makes sense of its returning senses were common during recovery from Carboxylic-magnacane. He tried to focus and see what was real and what he was imagining. As he’d noticed earlier, his naked body felt cold air all around it, and the snuggly secured limiter was still around the bottom of his horn. The various tight feelings he felt around his arms and legs when he tried unsuccessfully to touch his face proved his restraints were real too. The unicorn kept focusing and focusing, shaking his head to clear the cobwebs of his drugged mind, but when the full picture came into focus he wanted to scream.

He was in a dungeon, or at least a small room very much like one from a dungeon with smooth concrete walls, a rotted but still quite heavy door straight ahead, and the only illumination a significant amount of moonlight coming from a barred window to his left and through the cracks in the door. It wasn’t as cold as he’d thought it was at first due to the summer air, but that didn’t make him any less flank-naked. His ass rested on a pillow either purple or pink, and whatever was keeping his arms bent over his head and behind his back as tubular cushioning to rest his head and upper back (how considerate). His legs were extended in front of him, held in place by padded stocks around his ankles. Beyond that, tiny cords wrapped around every one of his toes and kept them separate from each other and attached to a metal bar on top of the stocks. The only thing he had on that even resembled clothes were an admittedly not uncomfortable furry collar with a metal tag he couldn’t read around his neck. It also took him a while to place the incredibly strange feeling of something rubber literally inside his body, just behind his crotch, displacing his anatomy in a circular shape: an elastic cock-ring had been placed around the base of his member, and retreated to the back of his sheath with it.

It was like he was some kind of doll or toy that had just been bought and how now been dressed up and put in a playhouse. They couldn’t do this to him, strip him naked and set him up for some kind of perverted display. He and Spike weren’t plastic, they were scales, fur and blood sentient beings with lives and futures and families and studies of magic-based fauna that needed to be completed by the end of the month!

Spike… a chill gripped him again as he remembered his brother. He then steeled his face. I promise Spike, if they’ve done this to you or hurt you in any way, I’ll send each one of them to the center of the sun, Elements or no.

He looked up at the door again. Odds were that an alert-alert spell had been placed on him and his captors notified that he’d woken up, but he still wanted to test his bonds anyways before he was approached and…

He looked down at his lap. Only his wide tip was visible outside his sheath, but the feeling of the displacing ring, so deep inside his body it felt it could come out his ass if he pooped, was a constant reminder of how much Nightmare Moon and her soldiers theoretically had to use against the unicorn if they made good on Nightwing and Knightlight’s earlier promises. He was so flaccid and concealed that didn’t seem like a remote possibility to him, but they had apparently gotten the band on in the first place.

He tried to tug his arms forwards.

No good. All my potential angles are restricted by something else, and I’m so strained I can’t risk breaking something.

He used his free fingers to try and feel the ropes around his wrists.

Damn. Just out of reach, and they feel like they’re knotted on the insides of the bars anyways.

He tried scooching himself forward.

Interesting. These stocks are clearly of the highest quality: despite their padding, they hold my ankles secure under pressure from either direction.

As he struggled and experimented further, Dusk learned he couldn’t even tap his head with his elbows because a thick pole was between the two and his wrist bindings were wide. The pillow in his lower back also had an inward curve to it that greatly hindered horizontal wiggling. This setup was indeed like a Ponie dream house in that he fit it perfectly, and without his magic he wasn’t going anywhere. So the unicorn stopped and thought again on his captors.

Nightmare Moon. She’ll be a dark blue alicorn… possibly. She wants to bring about the eternal night, and she’s probably got me like… he looked down at his crotch again. This to get to Celestia. After that I’ll probably be killed… hypothetically speaking of course. Celestia won’t be as easy to capture, and I already told them I’m no hostage. The Princess of the Sun-

What he’d first dismissed at an animal or water dripping somewhere he realized was in fact hooves- heavy ones- on the stone floors outside, and they were getting closer. The cell suddenly felt very cold again. There was only one pair, but whether it was the Demon of the Night herself or one of her lackeys sent to prepare him somehow, he was in deep shit.

He looked down at his body one last time.

I can’t be seen like this!

The hoofsteps stopped outside his door.

They can’t just do this to me; wrap Celestia’s most faithful student up like some perverted Hearth’s Warming present!

There was the unlocking of the door’s bolt, and with a brief creeking the rotted door was opened. When the figure in the doorframe was swiftly revealed to him, Dusk really did scream.

Oh my Celestia! Oh my Celestia! Oh my Celestia! It’s a dark alicorn, just like the one from the illustrations! It’s Nightmare Moon, only real! She’s a thousand-year old demon and she’s standing right there, smiling at me! She’d pure evil! She’s gonna eat me alive with those terrible teeth! She’s… she looks a lot like Celestia, only shorter.

“I see my reputation precedes me,” she spoke. Her voice was calm but not calming. It wasn’t deep or in-equine like the supernatural Derring Do villains he read about, but it still commanded authority, and so Dusk fixed his gaze on her dark face, which seemed identical to his teacher’s, if perhaps slightly rounder. “At least for you, Dusk Shine. I would never have allowed my lover to travel so weakly guarded, especially around such a time, as you’ll soon find out.”

“What do you want with me? Wh-where’s Spike?” Dusk asked nervously, having recoiled his body as many millimeters away from Nightmare Moon as he could while she addressed him.

“Your dragon pet?” Nightmare replied is a surprisingly subdued tone, tilting her head to the side slightly before returning to her previous composure. “I assure you, we have no intention of harming such an innocent little creature,” she pulled the door shut behind her and stepped inside.

It was then that Dusk noticed a variety of things that had escaped his notice earlier. Firstly, all the padding related to his binding was pink, including a spare pillow that lay to the left of his trapped feet.

He’d been so focused on the villainess’ dark complexion, black wing feathers and charcoal horn before though that he hadn’t noticed what she was wearing. Her “armored” helmet was actually a soft felt imitation that wrapped around her head but let her long, blue mane that seemed to sparkle and flow gently in a wind only it could feel, just like her counterpart. It looked like part of a themed pajama set, but when he looked down the rest of her scantily clad body the unicorn whimpered. Her open palm-sized, perfectly rounded breasts were hidden only by a very small blue blouse, whose insignia patterned cups- if they could be called that - concealed nothing above or below their nipples; had her tits shook at all when she walked, it’d certainly have been shaken off. The blue thong over her apparently hairless crotch that added to the theme with a small crescent moon symbols was the same story, and so Dusk could see her Cutie Mark easily. But to make her presenting appearance much more than a simple bikini, her long, shapely legs were clad in soft cotton thigh-high blue and black stockings, and her arms in similarly themed gloves that, counting their insignia, went all the way to her shoulders, but were devoid of fingers.

Dusk Shine was simply stunned by her beauty and how she was displaying it. Of course, Dusk knew objectively that Celestia had bigger breasts, longer legs and was far more vibrancy, but Nightmare Moon was making her first impression with him dressed in what was considered the most intimate, sexualized attire in Equestrian culture. Despite the cool air, the strange feeling of his cock band between his organs and, well, she was his mortal enemy who had abducted him and his brother, blood began to flow to Dusk’s face and crotch without him realizing it.

“As for you, however… My spies have told me so many wonderful things about my sister’s newest toy.”

Sister. The book had been clear on Nightmare Moon’s origins, but hearing said aloud, by the demoness herself… Dusk felt offended.

“You- you have no right to call yourself Celestia’s sisss-...” Dusk tried to declare bravely, but the dark alicorn baring her sharp teeth in a grin caused his words to fizzle out, and him to again recoil as far as he could, grimacing nervously.

“My brave bat-ponies gave their formal apologies to me for alluding to your future I hoped to keep a surprise, Dusk Shine,” she walked towards him, or rather, his stock-held feet and the pink pillow beside them, and the helpless unicorn focused on her fingerless gloves as she walked around his purple feet and knelt down on the pillow. “But I’m sure you’ll lie about not enjoying it just the same.”

“Waaaaait!” Dusk screamed at the top of his lungs a moment before Nightmare reached out and touched his feet that were held perfectly still despite their owners quaking. The scantily-clad mare did indeed pause and look up to his face. “Wh- what did your spies say about me and Celestia?” he asked frantically. He knew the answer, he was just stopping it from becoming self-evident for as long as possible. “W-We- If you want to humiliate Celestia you- WAH! Dusk cried out as Nightmare Moon, tired of waiting, brushed the tips of her fingers across the arch of his left foot quickly, which true to her spies’ word, got the cute purple pony screaming louder than ever instantaneously.

“Oh, my adorable, purple little pony...”

“WAH-WAHAHAHA-NO!” Dusk cried and writhed in his unbudging binds. Twisting and pulling on his tightly bound wrists, knocking his head against the cushion behind it, trying to curl his toes against the tiny strings looping between them that held fast, all to create direct pain and distract him from the knismesis and gargalesis sensations practically burning his most sensitive body part, but of course it did no good.

“AHAHA-STOPAHAHAHA!”

Celestia learned of Dusk’s now infamous ticklishness shortly after he became her student, and years later it became her secret weapon in bed. It didn’t matter how much the poor unicorn tried to apply mind-over matter and keep his breath regular, the moment fingers or feathers danced across his feet, tummy, armpits or neck he would shriek himself breathless as he entered his personal Tartarus of constant teasing that made him hate his own skin. And now, Nightmare Moon knew that.

“-I’m perfectly content to humiliate you this afternoon.”

“AHAH! EEEEEHAHAHAHAHAHASTAHHHHHPPPLEEEEEEEEEHEHEHE! He screamed, writhing violently side to side even though his tortured soles clearly weren’t going anywhere.

“But why should I?” the dark alicorn asked rhetorically in a rather jovial tone while she continued energetically dancing both her hands across the full lengths of the puffy, tender bottoms of his feet, moving her muzzle closer as if studying them scientifically. “When you learned of the fate your spineless so-called guardian condemned me too, you took it upon yourself to assist in my banishment.”

“NOAAAAAAHHH! THAT’S-EEEEEEEHEHHEHE!” Dusk tried to protest, but couldn’t speak a coherent sentence in Nightmare Moon’s soft, prancing grip of terror any more than he could in Celestia’s almost identical one. Besides, due to that very connection, his mind was soon going other places.

“EEEHEHEHEHEHEAHAHAHAHAHA!”

“-Frankly, I figure allowing you to hold the exact same position you had before in the new Equestria is a great mercy.”

“AHAHAHAHAHAHAHAHAHAHAHA!” Dusk screeched and squirmed, his own two feet once again host to the most terrible cancer Pony had ever known. He didn’t even notice the cock-band leaving his insides, he was so caught in the throes of the onslaught of pain disguised as pleasure that began in his soft feet and shot through to his brain and lungs like lightning.

“BWWAAAAAHAHAHAHAHA!”

“Case in point,” Dusk felt the greatest relief he would feel all night for the single second it took the scantily-clad demoness to gesture at his almost bloated erect, oversized cock with her right hand. “You’re proving my spies correct in their analysis of my sister’s newest fucktoy: for all your books and liberation philosophy, you really are nothing but a fat-cocked slut who needs a proper mistress.”

“Eheh- eheh- AHAHAHAHAHAH!” Dusk tried to look down at his own erection, but could only catch glimpses of it before he was back to swinging his head around in hysterics. His purple face still turned red though, because even if he fully understood that erections were involuntary and how psychological association worked, he was still now in the exact same position he spent many of his greatest nights with Celestia in, in front of her exact opposite. He would’ve tried to think of disgusting and terrible things to calm himself down, but he knew from experience he’d only end up thinking more about his captor because he didn’t want to think about her, just like Stallion King had written in his books.

“NAHAHAHAHAHAHAHAHAH!”

Every time the unicorn’s spasming neck brought the dark alicorn into sight for a fraction of a second, his cock felt like it was getting an extra pump of blood, not just because she was beautiful, but perhaps, and this thought truly scared him, because she really wasevil was well.

The only thing Celestia’s most faithful student loved more than learning was being tied up and fucked by a powerful mare. For years Celestia and her horny subordinates had helped him with that, but they’d always been pretending being anything more than loving teachers and friends. Nightmare Moon was doing exactly what Celestia did, but was playing for keeps. He didn’t enjoy having no say with his own body, not by a long shot, but as the gorgeous demon of the night forced him to laugh far past the point of burning lungs and splitting sides, he was terrified by the fact apparently known to both of them: that he had the capacity to love being a sex slave. What happened next only made things worse.

It took him several seconds to realize his tormentor had stopped. The “pain” in his feet slowly subsided, and it became easier to catch his breath. He leveled his head at Nightmare Moon in front of him with a cheek-hurting smile still on his face.

“*pant**pant**pant**pant* Whaddo- *pant**pant* what’re you going to do to me in general?”

The dark alicorn was resting her hands on her knees and smiling a more adoring smile as well.

“Won’t it be wonderful?” she asked dreamily, clearly alluding to her endgame for Dusk, which wasn’t what he’d meant, but she obviously didn’t care. “All the greatest meals, all the exercise and recreation to maintain your form, all the books and knowledge you ask for, regardless of the dark magic or previously forbidden history they contain…” she made eye contact with him again, and bared her sharp teeth in a grin and her horn ignited in dark blue. “And all I’ll ask for in exchange…”

Dusk suddenly gasped at the feeling of something- something soft, furry, and serpentine in shape- becoming the second thing to encircle his cock. He looked down to his lap and saw a strange, ash-black feather so long and so thick it could only belong to a Nightmare Moon’s own massive wings. Its bending stem was gripped by the alicorn’s glowing magic, and no sooner had he looked down than it was pulled upwards, the hundreds of tiny hairs left to brush and tease his engorged and ultra-sensitive member as they spiralled up. Dusk almost wished he could laugh at the tickling sensation on his large purple cock, but instead he was given the exact fleeting, taunting pleasure that they both knew would have him begging for proper release before long. He felt his balls pumping even more blood into his member, as if being even more sensitive would help.

“-Is a sexy little stallion who can satisfy me in bed!”

Dusk opened his mouth to respond, but then froze when the alicorn feather flicked across his cockhead, sending electric shivers throughout his body. And then it did it again, and again, and while Nightmare Moon smiled a fillyish smile, Dusk shut his eyes and gritted his teeth as he tucked his head down, trying to shut the teasing out. Not only did the demoness want him as a sex slave, but she was going to sexually humiliate and torture him until he begged her for such an honor. The idea sounded absurd on paper, but Stockholm Syndrome was very real, especially when one’s captor, shamed as he was to admit it, had so much in common with his lover, and clearly knew how to make him beg.

The purple unicorn was about to run through Shining’s tactics for resisting brainwashing when he burst out laughing again. While the feather was still slapping and twirling and poking at his cock, turning his whole crotch into a smoldering area of heat, Nightmare Moon resumed her attack on his feet, this time with another, smaller feather to scrape the hypersensitive areas between his spread toes. From that point on, his vocalizations ranged from mad shrieks to painful fits of giggling, but he never accomplished an instant of coherent thought as the onslaught dancing of fingers and feathers tore his feet apart with what would soon be indistinguishable with pain, and the dark alicorn expertly slashed and dabbed at and sometimes even lightly squeezed his cock until he was sure all his pent-up cum -currently slowly, tortuously leaked from his tip, lubricating his head and shaft and making Nightmare Moon’s job even more fun and easy- would explode like a theorized mega-spell and hopefully kill him. And well beyond that point, too.

Didn’t she have a princess to capture and an eternal night to begin? By Dusk’s best estimations, this was their fourth session together. He was usually- no, always half-dead from oxygen deprivation and dehydration by the time she left. She’d said something on her ways out and in the first and second times, but now she just came and went. Catching his breath in between sessions was never as satisfying to the captive unicorn as he always thought it would be while under the feather; he’d simply sit in darkness, his erection dying slowly and bound limbs becoming sore again after all his struggling and squirming had brought life back into them, speculating as to… well, everything beyond the tiny confines of his cell. Was Spike okay? Was Celestia okay? Had Shining learned of Nightmare Moon and launched any sort of counterattack?

And of course, before he knew it, the door would open again and without a word the beautiful dark alicorn would put tears in Dusk’s eyes from laughing so hard and long. He had even less of an idea how long each set of his forced hysterics lasted, but Nightmare Moon always seemed to push him, his cute purple featsies and now dark-pink member some distance beyond the point of sanity, but before he actually fell unconscious.

No, she was determined to prevent her adorable little captive from being desensitized to her torments or going into that strange sort of shock this sort of thing could put her lovers if she wasn’t careful. In Luna’s old bedroom she was working on new vertical constraints for the unicorn that would have portals to the dream-realm locked around his feet. But for now, while she didn’t need to fix what wasn’t broken with the feathers, she had made use of a sensitivity aloe Luna had first mixed for her sister. As soon as the last bottle of pink, soap-like liquid was fully absorbed into his now incredibly soft, supple feet bottoms, she’d apply another, and simultaneously rub it in and tickle him with her hands and a pair of uber-soft levitated brushes.

Dusk didn’t know exactly when he’d started using his scant free breaths to beg, but now he was.

“PLAAAAAAEEEEEEESE-AAAAALLLLLL- *squeak* *squeak* *squeak* I’ll doooooo- AAAAAAAANYTHIIIIING!” he cried into the air, his eyes swollen and red.

Nightmare Moon squeezed his aching cock hard with the feather while applying extra speed and ferocity to his foot-arches with her hands and toes with the brushes.

“Renounce Celestia?” she asked playfully.

“YYAAAAAHHHOHOHOHOHOEEEEEESSSSS!” Dusk responded, clenching his teary eyes closed.

“Accept a collar-tag and brand?”

“PLEEEEEEAASE, STAAAAHAHAHAP!”

Dusk wasn’t actually sure whether or not he meant what he was promising. The rope burns around his wrists were evidence how much he’d sacrifice just for a second of free movement to either give his dick just the tiniest piece of release or shield his defenseless feet from the fingers and brush bristles that felt like they were tickling him straight into his bones, but he just had to say whatever she wanted to hear until she stopped, right?

“Do what I’ve done to you to your dragon friend, and then tell your brother and foalsitter to surrender?”

Dusk figured seeing his friends under any circumstances was priority one, and once there they could communicate and work out a plan. Although there is often a fine line between fingering and making excuses.

“AAAANNAHAHAHAHEEETHING!” he wailed into the room.

“Good to hear,” she said cheerily. And just like that, the tickling and teasing stopped.

His dick noticed the feather it now felt cold without pulling away almost immediately, but his feet were so sensitive by now his nerves kept firing for a few seconds afterwards. His once roaring laughter faded to silence, and he craned his neck back to draw one massive breathe into his burning lungs before leveling his still smiling, teary red face to look at his captor, panting.

Nightmare Moon, however, had already put her various tools to the side, and had gotten off her pillow to crawl around to Dusk’s right between him and the wall. Despite everything, the unicorn was confused until she put one fingerless-gloved hand on his penis.

He shivered, not because her fingers felt cold, but because now even the lightest touch from something more solid than a feather nearly made him blow his massive built up load instantly. She gently closed her fist around his member and slowly slid down to his base above the band that she was happy to see had worked perfectly. Dusk winced trying to stay in control of himself, as if it in any way maintained his dignity.

“Don’t think for a second that your training of this sort is finished,” she ran her free hand across his even more disheveled mane, teasingly brushing one finger around the base of his horn, which made him shudder again. “My handsome little fucktoy.”

“Will you-” Dusk cautiously looked her in the shining blue eyes. What little leeway he’d gotten by surrendering he couldn’t jeopardize by being too assertive, but every minute he didn’t know was a minute his brother could outlive his usefulness or worse. He had to remember that as beautiful and sultry as Nightmare Moon was, she was still pure evil. “Will you *pant* take me to Spike? I’ll tickle him or do whatever-”

But then Nightmare Moon dropped her head into his crotch and engulfed his cock with her mouth in one fluid motion. The encircling of his shaft by her lips brought his volcano the tiniest of tremors away from eruption, but then her hand squeezed his lower half tight and she sucked inward with an iron lung, slowly bringing her head back up.

Dusk didn’t cum so much as his entire tip burst open and his entire groin area dehydrated and shrunk as accumulated hours and hours of teasing blasted through his cock and into the beautiful alicorn’s mouth with enough force and volume to bloat her cheeks and nearly cause her to choke in surprise.

Dusk didn’t notice her brief humiliation though, because for the thirty seconds hot seed shot through his piping, and another thirty before he came down, his whole body was in such ecstasy he thought he’d lost his mind forever. His eyes couldn’t roll back far enough, his tongue ought to fall out of his mouth, and only his restraints stopped him from from bending his spine and neck backwards until they snapped, or crushing his feet in on themselves. Celestia had driven him to heights he never thought possible, but Nightmare Moon had filled his veins with the light of the heavens themselves. By trussing him up, reducing him to the status of a fucktoy, tickling, teasing and abusing him, Nightmare Moon had given him the greatest orgasm of his life, and for the highest few seconds of his seemingly endless orgasm, Dusk forgot to hate it. It was only a few seconds, but mortal terror gripped him afterwards when he realized that was all the dark alicorn needed to build on.

The last time Celestia remembered something going this wrong was a thousand years ago, although probably not still to the day. She was naked, spread-eagled by a metal rack, wings bound and horn limited in a room illuminated only by the alternating glows of the four gemstones that surrounded her on runed stands. The lights of the stones would change color and brightness with the different spells of the two hooded unicorns who's coming, going, and discussions were the only way for the Princess of the Sun to tell how long it’d been since she’d let her guard down in the Ponyville city hall and let herself be taken.

Of course she regretted letting herself be captured now. The unicorns only whispered to each other while in her presence, but they were obviously planning a ritual of some sort, she’d made out enough to tell that they were A. what they were planning:

“*Snicker* Send me to the moon? It seems turning evil did nothing to make my sister’s sense of humor- *bzzaaap!* Ow!”

And B. Less humorously, they were getting closer and closer to accomplishing their goal. For a millenia Equestria’s premier princess had never smiled as brightly knowing her sister was alive and enduring absolute and utter isolation. The thought of being away from her little ponies for even a week while they were at the mercy of her insane and corrupted sister was more than Celestia could ever hope to bear, but she couldn’t dwell on that for now.

Dusk was out there right now. He’d met the other elements, and if he wasn’t friends with them already, even in the dark she recognized a room of their old castle, so Dusk had no choice but to become the spark soon. But “soon” passed a long time ago. Celestia wasn’t particularly dehydrated, hungry or tired, but that was quite hard to do in the first place, and if she had to guess it’d been 30 hours since her capture at the very least.

All the worries she’d had about sending Dusk away before creeped back to her as the hours dragged by, no matter how hard her disciplined mind tried to suppress them. She hadn’t seen him since he’d left, which was part of the plan, but still left her with no confirmation he’d even reached Ponyville. The prophecy had said he’d save Luna, but prophecies weren’t always 100% accurate.

Around the estimated 40 hour mark, Celestia closed her eyes and vowed that if her sister had killed Dusk, or Spike, or Shining or Cadence or a anypony since her return, no chains would contain the full wrath of the sun, and there’d be no banishment, no mercy and no redemption.

And just like that, the doors opened again. Celestia knew it was time to finally see the pony her subjects had dubbed “Nightmare Moon”, because both the unicorns were already in the room.

Both heavy doors swung wide open theatrically, and a fully armored Nightmare Moon strolled into the room with a devious smirk. A burning rage she’d never thought she’d feel for her sister, or the being that was formerly her sister, ignited in Celestia. She hadn’t even clenched her fists in anger though, when she caught sight of the purple pony walking behind her to her left.

“Dusk!” she cried out elated, not caring that he was as naked as she was and probably there to be a hostage against her, only that he was alive.

Her smile faded though, when Dusk didn’t respond, and she saw that in addition to being naked, he walked behind Nightmare Moon with no restraints besides an improved golden key-locked horn limiter and a dark collar tagged with a tag depicting a crescent moon. His head was hung low, but his face was not one of despair, but a restrained smile.

“Hello Celestia,” Nightmare Moon greeted in a deep, threatening voice. The bound princess quickly shifted her focus back to her true adversary, now standing a few feet away from the rack. “I apologize for your current accommodations, but guarantee you something much more spacious as soon as my two loyal mages and I have completed the banishment spell.”

The two hooded unicorns bowed in unison, and moved to opposite ends of the room to give their queen space.

“You may have captured my most faithful student,” the sun princess gestured to Dusk with her head. “But since my sister departed I’ve found new talented ponies, raised new armies, even made another princess, all of whom can defeat you even without the elements.”

Nightmare Moon was taken aback by how confrontational Celestia was being. The sun princess had banished her even after she’d made clear that she could and would take Equestria from her, and later spend decades conconcting and executing a plan to “rescue” Luna, but now that they’d finally met again, she was threatening her with armies and the new alicorn she’d kept away from the rescue scheme (not that a goddess of the night really would be afraid of being replaced of course)? The dark alicorn’s smile didn’t falter amidst her confusion though, and she turned towards Dusk at her side, who continued looking down.

“Oh, I wouldn’t put too much faith in your friends, Celestia,” she said, and the bound princess’s heart sank. “Your most faithful student, your lover, your supposed spark to save a lost cause…” her arms bore metal gauntlets, but her hands had only thin fingerless gloves, so when she used one hand to gently grope and caress the naked unicorn’s flank, and the other to lift his sack and idly stroke his hardening cock, Dusk shut his eyes and lifted his head up to purr and giggle at her soft touch. The dark alicorn kept her eyes on Celestia though, correctly guessing that the ensuing look of shock as if it wasn’t her who taught such acts to Luna would be priceless. “Three days and he begs to be my proper concubine.”

Dusk opened his eyes and his mouth, but then shut the latter and looked down again before Celestia could see him. He had swore no such thing; only that he’d obey Nightmare Moon for the time being and follow her lead in the meeting with his mentor in exchange for Spike and Shining’s safety. By the time any banishment spell of such a caliber was anywhere close to complete, they’d have long since been noticed missing, tracked down and rescued.

Inexplicably though, the thought of being rescued and seeing Nightmare Moon banished or disintegrated made Dusk feel the chill or the room even colder. When the dark alicorn took her hands back, he had to curl his toes to stay still, aching for her warm touch to return.

“D-Dusk,” Celestia stammered, her anger replaced by despair and heartbreak. She’d at first believed Dusk would be like her son, but he’d become her prodigy, her lover, her hero and potential successor; everything she’d ever wanted and hoped for in a pony, and yet he now stood naked and submissive next to her new arch-enemy, and moaned at her molesting touch? No. She blinked away her forming tears and stared forward intently and authoritatively. “Dusk Shine! I am princess Celestia of Equestria: you teacher and your friend! Either this is one of Nightmare Moon’s illusions, which I doubt, or you’re letting down Equestria, your family and yourself by succumbing to Stockholm Syndrome. You can fi- mmmmm!”

“Oh, shut up!” Nightmare Moon snapped, a red ball-gag materializing in the white alicorn’s mouth mid-sentence. Celestia gagged for a second, then growled and stared daggers at her captor, but the dark alicorn looked again to her new fucktoy, who she could see was struggling not to protest the treatment of his mentor and former lover. “Dusk, darling,” she held his chin up to look at her. “You’ll tell your brother and foalsitter to surrender, right.”

Dusk nearly choked. This wasn’t part of the agreement.

“O-Of course, my queen.”

“And you’ll help ease your dragon friend into his new role as my assistant?” she smiled her sharp-toothed smile.

“I- I’m sure he’ll love serving you, mistress.”

“Huuuuusk!” Celestia shouted through her gag, and Dusk Shine couldn’t help but glance at her. She was really believing him! This was tearing her up! He had to let her know somehow that he was just stalling and working on an escape plan him-

“Excellent answer,” Nightmare Moon said, letting go of his chin and kneeling down, sliding her hands sensually down his body as she went in order to gently position him, and his already hard dick, to face her. It was now or never to tell Celestia!

Once Nightmare Moon’s face was in his groin, he quickly turned his head forward and winked at Celestia, whose eyes went wide and screamed angrily in response. Realizing she didn’t understand, he was about to think of another subtle way to communicate with her when he heard a metal plate clatter to the ground, and he turned back just in time for Nightmare Moon to samwich his cock between her massive, blistering hot breasts, and his whole mind went blank.

She wasted no time in using her blue chest-pillows to level his dick with her mouth and engulfing his tip. Dusk had to fight to keep his arms at his sides as his entire body screamed in ecstasy. Every time he was somehow inside not just Celestia it appeared now, but any alicorn, he’d forget about his family, his assignments, his name, everything but fucking and being fucked by a goddess that ponified beauty and strength, and now Nightmare Moon was lathering and sucking his cockhead with her fast and skilled mouth and pumping his shaft with somehow both soft and firm mammaries.

Celestia saw her former coltfriend bite his lip and look down at the dark alicorn in front of his groin. He’d only ever made that face once in her company; right before their first time together. Before the bound princess had screamed and struggled, but now she just watched the incredibly handsome unicorn curl his toes and hands and try to resist thrusting into the night demon’s mouth, all five ponies in the room well aware that he wouldn’t last long like this. Nightmare Moon had taken Celestia’s sister and now her special somepony; she had failed, and it was only natural that the dark alicorn took Equestria now. The princess of the sun was too desperate to be angry.

Nightmare Moon pumped and sucked and licked until Dusk Shine’s cock was a wet, hot mess. If he concentrated, he might’ve been able to hold out longer, but he subconsciously knew that alicorn’s always much prefered to be in total control.

His eyes rolled back and he exploded with the dark alicorn’s final squeeze. He shot more than enough for the next minute to drown her, but she swallowed and swallowed the hot slag so not a single drop sullied her face or battle helmet. When he finally died down, Dusk was so spent he bent forwards in exhaustion, trying to rest his hands on Nightmare Moon’s shoulders, but she took hold of his midsection mid-bend, and effortlessly lifted the delirious unicorn up into the air on her right shoulder, planting a loud, but not terribly painful smack on his flank.

“An hour?” she asked behind her casually, turning and walking back to the door.

“Give or take, my queen,” one of the mages answered from the sides of the room, both taking it as a signal to return to the gems and their work.

“Send her away the moment you can,” the dark alicorn ordered, opening the door. Before exiting she took one last look back at her pathetic traitorous bitch she had once called her sister, who she saw has hung her head and was about to cry. “I’ll be busy the next few days finishing this cute little puppy’s training.”

Dusk’s eyes finally opened all the way again, fearing a return to the special tickling rack in the dark alicorn’s bedroom that had made him accept this deal in the first place, but she smacked his flank again, this time on the other side, and shut the door behind her.
