Corporal Punishment

Shining Armor walked through the busy Canterlot streets, reminiscing of the days when he walked these roads as the captain of its guard. While the Crystal Empire was an amazing place to be, he could never quite forget the life that Canterlot had to offer.

As he passed through the market square, he glanced around the stands instinctively, a keen eye overseeing every citizen that walked through. If he was going to see any action, it would be here. What better place for a thief than somewhere with abundant open merchandise and a large crowd to hide in.

Sure enough, Shining spotted the usual vagrant type--old brown cape and hood to cover her identity, and tense, shifting body language with eyes that surveyed the crowd for anyone looking at her. She never spotted Shining. His smile grew as the muscles in his legs prepared for the chase.

As soon as she passed by a jewelry vendor she bolted. The vendor yelled something, but Shining Armor didn't care to listen.

"Make way! Royal guard coming through!" He shouted. Even though he wasn't wearing his armor, most of the Canterlot residents knew who he was, and in an instant made a path where he was facing.

With years of training behind him, he practically flew through the street towards the thief. She caught sight of him, and her face turned from curiosity to fear. He locked in on a few details to be sure not to lose her: a blue mane and tail and a light yellow coat. Her cape covered her cutie mark, but there wasn't much more he needed.

Despite his larger size, he gained on her much faster than she could ever expect. Every pony she had to dodge and duck around slowed her down, bringing Shining that much closer to her.

Just as he thought he could grab her tail in his teeth, he slammed face-first into some poor stallion on his daily errands. Whatever he was carrying with his horn got thrown halfway across the street, making everyone glance over at the scene. She had slid under him, mixing in with the crowd ahead of Shining. He quickly apologized to the guy, then got right back onto the chase.

The crowd ahead of him was much thicker than before. He barely had room to walk, let alone search for the thief. He was determined though, and pushed his way through the crowd, looking for the criminal.

He searched on either side, then on each of the corners of the crowd, but it looked like her small frame prevailed this time. Shining was just about to chastise himself for losing her when he spotted the same brown cape and blue tail.

"Ha! Nowhere to go now thief!" He shouted, beginning his charge towards her.

This time, instead of bolting, she turned to face him and let out a very lady-like gasp. Shining hit her with all the force of a freight train, knocking her right to the ground with him on top of her. With his victim successfully floored, Shining went in for the pin and cuff.

Shining gave his sternest look right into her red eyes. “You have the right to remain silent,” Shining said, ripping off a portion of her cape to use as a quick rope to tie her up with.

“What on Earth do you think you’re doing!?” The mare said in a thick Prench accent.

“Justice. Thieves like you aren’t going to get away while the guard is still around. Now shut up and face your punishment.” Shining Armor wrapped the mare’s legs up tightly with the torn piece of fabric. Shining stopped for a moment and noted how soft it felt against his hooves.

“Huh. Is that satin?” he asked once his target was properly subdued. He ran a hoof over her cape, taking in the feeling.

“Yes! And you just tore it! What is the matter with you!?” She said, trying to thrash out of his hold and glaring daggers at him.

“Stow it, we’ve got to get you to jail, thief.”

Shining tossed the poor mare over his back with his magic, not even concerned with how rough he might have been.

“I am not a thief! I’m here on royal business!” The mare shouted, trying to thrash out of her bonds and off of Shining’s back. He held her tightly in place with magic, giving her no chance of escape.

“Save it for the judge.”

Shining trotted his way back up to the castle. He was supposed to meet his wife up there pretty soon anyway. A prideful smile crossed his face at his accomplishment. He hadn’t even been back in the city a day yet, and he was already working to make it a better place. He imagined the glorifying headlines and the praise he would get already.

_________________________________________________________________________________

Shining walked through the halls of Canterlot castle, the smile never leaving his face. After joking around and catching up with all his old friends in the guard after he brought that criminal in, he was trotting proudly, ready to tackle whatever royal meeting he’d been brought here for in the first place. He just had to find his wife first.

Conveniently, she rounded a corner in front of him. She did not, however, look very happy to see him. A stern look crossed her face at the sight of him. Cadance marched right up to him, and Shining knew it was going to be one of those long winded lecture moments. As to why, he had no idea. He shot her a happy greeting to at least try to defuse whatever she was upset about.

“Hey honey. You’ll never guess what I did this morning,” Shining said brightly. This only further upset his wife.

“It’s been all over Canterlot! I told you to behave yourself, Shiny. This is exactly why I just told you to stay in the castle. If you hadn’t been out in the streets playing guard then—”

Shining put a hoof up to Cadance, cutting her off. “Woah, slow down, honey. What are you talking about?”

“Slow down? Celestia is on a warpath looking for you and you’re telling me to slow down? How do you—”

“Shining Armor,” boomed Celestia’s voice. Her stern tone would strike fear into even the strongest of stallions, and Shining Armor was no exception. His heart sank when he heard his name come from the normally gentle Princess. Cadance backed out of her way beside Shining Armor, her head held low like a scolded dog, embarrassed to even stand beside her husband.

Celestia looked down her nose at Shining, her glare intense enough to make even the former captain of the Canterlot guard gulp in fear. “Meet me in the royal court room immediately.”

Her words were curt and precise. After she’d said them, she left both ponies to it as she turned tail and headed there herself.

Shining’s eyes were wide in terror. A member of the guard was only personally summoned to the castle court for the highest of offenses. What could he have possibly done to warrant such drastic measures? “W-What... I...”

“We better get going. Come on, Shining, let’s get this over with,” Cadance said, trepidation clear in her voice.

Shining walked down the hallway towards the courtroom with his wife, trying to think of what he might've done to warrant such an action. Did he step on some sacred bug? Did Celestia find out about the erotic fanfiction he'd been writing about Luna? That must've been it. Shining felt himself sweating at the thought of having to face her now. He concocted a sea of apologies, but now that it had gotten to this level, it wouldn't do much good.

He could see the headlines now: "Former Captain of the Guard Court Martialed for Fictional Coitus!".

Cadance opened the door to his ultimate doom. When they finally arrived, the other three princesses were already present. The giant marble courtroom was guarded at all exists by the most experienced royal guards in Canterlot. There was no chance of escape now. Shining Armor, his head hung low in shame, took his place in the center of the room, looking on at the giant thrones that all the princesses sat in.

The tension in the air was palpable. Silence ruled for a few moments as Shining carefully glanced across each of the princesses. Luna and Celestia held looks of disappointment, while Twilight and Cadance looked at him with apprehension and sadness.

It was too much for him to take. The guilt inside him built up; he had to release it somehow. He looked Luna in the eyes with a remorseful expression and shouted, "I'm sorry for shipping you with my wife! Please forgive me, Princess!"

Instead of shaking their heads and brushing off his apology, all but one of the princesses looked at him in complete confusion. Twilight had a dark, embarrassed blush on her face, apparently the only one who knew what that statement meant.

Celestia cleared her throat, trying to push the awkwardness out of the air. “Shining Armor, you are here today for the act of assaulting and falsely imprisoning a foreign emissary. How do you plead?”

“Assaulting a... What?” Shining asked, completely confused. Then it hit him; the only person he’d attacked today was that theif. In retrospect, she did have a very nice cape and definitely smelled of expensive perfume. “She stole from a jewelry vendor! I saw her with my own eyes!”

“The vendor identified the thief as having blue eyes and wearing a burlap covering,” Luna interjected, “The pony you apprehended had neither.”

“She was a Prench ambassador, Shining! That was the entire reason for this trip!” Cadance shouted at Shining, distressed, “We were supposed to improve foreign relations, not assault their citizens!”

Celestia raised a hoof to calm Cadance, then looked back over to Shining Armor. “Yes. Because of your haste to handle guard business, much work will need to be done to rectify the situation. I’m sorry, Shining Armor, but I have no choice but to administer the traditional punishment for someone of your ranking.”

Shining’s face drained of color at those words. He tried to back up and search desperately for an exit, but the grey unicorn guards had cornered him and pushed him back in place. Shining rubbed the back of his neck and laughed nervously. “C-Come on, there’s no need for that. It was just one mistake.”

Celestia turned to Cadance. “If you would.”

Cadance closed her eyes and nodded solemnly as her horn began to light up.

“No, anything but that!” Shining was standing up now, looking up at the princesses then behind him towards the guards who were slowly marching closer to him, smiles growing on their faces. “Life imprisonment! The death penalty! Eaten alive by ferrets! Please, just not that!”

“I’m sorry, honey, but you know we have to do this,” Cadance said, pointing her horn at her husband.

A stream shot out of Cadance’s horn and flew through the air like pink lightning, flying right between Shining’s legs and hitting him right in the dick.

His entire body was enveloped in a flash of magic, and Shining could feel the strange magic coursing through his entire system, changing him on the most integral levels.

The light faded and the dust settled. Shining Armor’s eyes fluttered open, slightly exhausted from the amount of magic that just enveloped his system. His vision focused back in, and he pushed himself back to his hooves. He rubbed the side of his head, noting how much softer his hoof was now. He looked down at his hoof, then back down his body. He let out a very girly gasp. He shifted his weight on his hips. There was a lot more space back there than there used to be.

Shining Armor grimaced as he finally had to accept the truth. He was a she now.

“Just relax, si--er, ma’am. We’ll make this quick,” One of the guards cornering him said.

“Come on, guys. We’re old friends. You couldn’t do this to your...” Shining trailed off, partly because of the overly feminine tone of her voice, and partly because she could clearly see the massive members of his former subordinates poking out of their armor and shining with precum in the sunlight pouring through the back windows. “...f-former captain, could you?”

One of the grey stallions licked his lips. “Sorry, Cap. Princess’s orders.”

Celestia turned to Cadance once again, getting off of her throne. “Cadance, Twilight, would you two mind overseeing Shining Armor’s punishment? My sister and I have business elsewhere that needs our attention.”

“C-Certainly, Celestia,” Cadance said in a shaky tone, having a hard time looking away from her husband/wife about to be gangbanged by three muscled stallions. Twilight didn’t say anything. Her blush never left her face and only grew darker with time. Celestia seemed oblivious to the young princesses embarrassment, even though Twilight’s eyes were as large as dinner plates and her mouth hung open slightly in horror.

“Good then. I will trust you to see hi-her home as well. We will postpone the conference until tomorrow. See you then, Princess Cadance,” Celestia said in an even, unaffected voice. Cadance gave her a weak nod, then both Celestia and Luna left the courtroom, leaving only the guards at the doors, the ones on top of Shining, and Twilight and Cadance left to watch.

Shining yelped when one of the guards grabbed him by the cheeks. To his credit, he was gentle enough. Shining hadn’t even backed all the way into the wall, so the other two stallions were circling her, checking out her new goods.

Her heart rate skyrocketed when she saw the cock slowly making its way up to her mouth. The burning blush on her face kept her frozen in place. Not knowing what else to do, Shining gave in and let it brush against her lips, eventually pushing past them and making its way down her throat. The foreign feeling made her gag against the new object in her throat.

For some odd reason, the feeling of a cock down her throat made a nagging pressure start to build up between her legs. The sudden drop in a few degrees on her backside and the slickness told the story. Her new body was enjoying the strange attention. One of the stallions behind her took notice, and propped himself up on her flanks, probing her new entrance with his throbbing dick.

Shining shifted uncomfortably as the shaft slid back and forth across her tongue and down her throat. Her eyes shot open wide again as the stallion behind her took the plunge, sending at least half his length into her new hole. Shining yelped around the cock in her mouth, and her legs jerked forward instinctively

She grimaced as more of the length penetrated her. She could feel every vein and bump as it slid past her walls until it bottomed out, poking her cervix. Shining tried to shift her hips around to a comfortable position, but being filled up so much with a cock almost as big as her hoof wasn’t something she could ignore. Shining whimpered around the shaft in her mouth, and tried to filter out the groans of the two stallions on top of her.

Cadance chewed on her lip as she watched her now-wife get spitroasted. As ashamed as she was, she couldn’t help but let one of her hooves drift between her legs. A spot was already forming in her throne, and she couldn’t just let Shining have all the fun.

Cadance shook her head. He... or she was supposed to be punished. She doubted Shining was enjoying this, but Cadance’s mind wandered to strange places, imagining herself in Shining’s place. Two cocks ramming her from both ends was enough to get any mare going, and Cadance was definitely no exception. Without even realizing it, her hoof slipped back between her legs and began to rub around enough to elicit tiny moans from the Princess of Love.

Cadance looked over to see if Twilight had the same reaction. Instead of apparent arousement, Twilight sat stock still in her throne, unable to take her eyes away from the scene, a dark blush clear on her face. Her expression was locked in a weird combination of shock and disbelief; Cadance would’ve laughed if the cocktail of hormones in her body wasn’t making her focus on other things.

“Psst. Twilight,” Cadance whispered, still having a hard time looking away from the scene on the court floor.

Twilight didn’t budge.

“Twilight, are you alright?”

It took a solid few seconds before Twilight was able to respond. “Sure, never better,” she said, never changing her expression, and never taking her eyes off Shining.

“Are you, uhh... having the same problem I am?”

“What? Wishing I didn’t have to watch this? Yes.”

Cadance cleared her throat. “Er, no. More like...” Cadance pointed down between her legs, and showed Twilight the slightly wet end of her hoof.

Cadance didn’t know if Twilight could legitimately get any redder. Twilight traded nervous glances between Cadance’s sheepish smile and her own groin. “M-Maybe.”

Cadance casted awkward glances around the room. She needed some relief. Watching something so explicit happen to Shining was more than her marehood could take. “We don’t, uhh... have to let Shining have all the fun. No one is really watching the two of us up here,” Cadance asked, rubbing a hoof along the back of her neck.

“Cadance! We’re family!” Twilight said, exasperated.

“Well it’s not like anyone’s going to find out,” Cadance said, a hopeful smile pointed at Twilight.

“This is not happening right now!” Twilight said, putting her hooves to her temples and shutting out the world.

Meanwhile, the third guard surrounding Shining was getting restless. While the other two christened Shining’s new feminine throat and marehood, he was stuck staring at his former captain’s soft new coat and features. The other guards were considerate enough to notice this, and both of them slipped their cocks out of Shining to rearrange her into a more suitable position.

Shining stood on shaky legs like a cat that just got dipped into a lake. She gasped for breath that the length down her throat wouldn’t allow her, and shifted her hips back and forth, trying to cope with the yearning her girl parts had for the dick that was no longer filling her insides.

Her respite wouldn’t last long. With her lighter weight, it only took one of the guards to grab her in a bear hug and turn both of them around so that she settled upside down on top of him. His cock slid up against the entirety of her slit. The feeling of his warm shaft against her wet folds made Shining blush as the thought of him re-entering her crossed her mind. The other two guards took their respective positions at each end of her.

Shining did the math. Three guards and only two holes. That could only mean one thing. Just as she realized it, the guard under her probed her ass with his massive member. The slickness from her marehood would help a little, but there was no denying this was going to be a tight fit. He started out slowly, but even the head of his cock sliding into her ass made Shining yelp in pain. The stallion at her mouth took the opportunity to indulge himself. With an open hole available, he slid his dick past her lips and a good way down her throat. With a better angle, he was able to get much deeper into her, even being able to see the bulge his member made in her neck.

Shining was in no position to protest when the third stallion took his place back inside her folds. The wet entrance and stretched flesh welcomed him quickly, and he got right back into the rhythm of pumping his length into her, making her moan around the cock in her throat.

The guard under her pushed his hips up, forcing his entire length into her tightest hole. The feeling of being filled up that much on both ends was overwhelming. Her entire world became reluctant pleasure, and Shining struggled to deal with the flurry of feelings her body was throwing at her. Part of her yearned for them to pound her harder, and that instinctive drive caused her to move her hips in tandem with their strokes.

Cadance on the other hand was getting tired of trying to convince Twilight to fuck. The wet spot on her throne had grown into a puddle, and she was going to get off one way or another. “Twilight, come on. I know you’ve thought about it at least one time before.”

“Cadance! That’s incest! It’s already bad enough that I have to watch... this,” Twilight said, motioning to the mare sandwich down on the courtroom floor.

“I’m the Princess of Love, Twilight. You can trust me with this,” Cadance said, hoping it would convince her.

“You’ve known me since I was a foal, Cadance. That’s just weird!” Twilight shouted.

Cadance knew she wasn’t getting anywhere like this. Now it was time for plan B: just do it and hope Twilight might forgive her some day. “Oh... Just hold still.”

Cadance pounced, grabbing Twilight and wrestling with her until they were both in the desired position. Once Twilight was on the ground on her back, Cadance forced her dripping marehood towards her muzzle, and dived face first into Twilight’s own glistening folds. Twilight yelped at the sudden invasion of pleasure. Cadance didn’t want to wait for Twilight to come around, so she pushed her folds onto Twilight’s muzzle, soaking her snout in her excitement. Cadance let out a content coo as the feeling of her sister-in-law’s nose rubbed against her. She continued lapping at Twilight’s pussy as she grinded her own on Twilight.

The stallions inside Shining were pumping into her harder and faster with every passing second. She was only allowed a few moments to breath every now and again, and even those were spent having to let strained moans pass her lips with her new feminine voice.

The stallion in her ass was the first to cum. His thrusts into her became shorter and more strained until they stopped entirely, with his full length hilted into her. Every drop of hot semen sent waves of electrifying pleasure inside of her. Her eyes shot open and her back arched at the strange feeling of warm seed filling her up until it leaked back out. She whimpered and squirmed, unable to get away from the new sensation.

The stallion in her marehood was next. With one last mighty pump, he drove his dick as far into Shining as it would go, making cum spurt out and pool up inside her, filling her up in places she didn’t even know could. She arched her back and writhed as the cum filling both her holes dripped out of her, unintentionally grinding herself on the cocks inside of her, making her moan even more.

Finally, the guard probing her throat let out a grunt and pulled himself out just enough so Shining had to taste every drop. The salty, bitter liquid clung to her throat and increased with every convulsion of the stallion’s balls. In seconds, Shining had a mouthful of cum that she had no choice but to swallow. She felt like the torrent of baby batter would go on forever. Every time she would swallow another mouthful took its place, making her taste every drop again as he filled her full with every spurt. Finally, Shining swallowed the last of it, and got to breathe at last. The other two stallions pulled out of her and sat her on the floor. Shining lay there panting, dripping cum out of every hole.

The guards professionally went back to their positions and waited for Princess Cadance to see the prosecuted out. Everypony waited at least another twenty minutes until Cadance got off grinding on Twilight’s snout.

_______________________________________________________________

Cadance and Shining Armor walked through the quiet Canterlot streets. The moon was low in the sky, and the events of the day were slowly starting to become a distant memory. For everyone except Shining Armor and Twilight at least. Shining was still stuck as a mare, her giggling wife refusing to turn him back because she was “too cute like this”.

“Honey, could you please turn me back already? The punishment is over with and I just want to go to sleep in my normal body,” Shining said, his voice still a bit higher than Cadance’s.

Cadance looked Shining over with lustful eyes. “No, I think I’ll keep you like this for a little while longer. Besides, I thought you liked shipping me with other girls?”

Shining’s face went beet red and she looked away from Cadance. While looking across the streets trying to get the embarrassment to fade away, she spotted a yellow mare with a blue tail, her blue eyes shining brightly in the moonlight. She snickered at the sight of the emasculated captain.

Shining perked up and gasped. This was the real thief. She hunkered down, ready for a chase, but Cadance grabbed her with her magic and pulled her close. “Speaking of lesbian sex. I have something back at the hotel I’ve just been dying to try out.”

“No! Wait!” Shining said, trying to stop her. It was no use.

In a flash, both Shining Armor and Cadance disappeared off the Canterlot street, reappearing back in their hotel bedroom. Shining armor was conveniently already tied to each of the bedposts with a couple of sheets, lying spread eagle with her wife looking over her with a devious smile.

“As I was saying...” Cadance pulled a massive black dildo out of her bag, flipping a switch on the bottom to make it vibrate like a chainsaw.

“Cadance, wait. Cadance, no!” Shining begged as she writhed against the bonds.

Cadance’s smile crept up from ear to ear as she squirted out a big glob of lube onto the tube. “Cadance yes...” Cadance said, moving in.

“AAAAAAAAAAAAAHHHHH--O-Oh~.”

____________________________________________________________________

Twilight sat back in her library in Ponyville motionless. Her eyes looked out the window, a thousand-yard stare plain on her face. For almost three hours she sat there, paper, quill, and ink at the ready, but with no idea what to say.

Finally, without even looking down at the paper or changing her expression, Twilight picked the quill up with her magic and began to write:

Dear Princess Celestia,

Never involve me with courtroom affairs again.

The New Life

Something has gone wrong. We don't seem to have an archived copy of that chapter.
