Meeting Mr. Big...Macintosh

Cadance was fast asleep, but Shining Armor was wide-awake. Tonight he felt a familiar itch. An itch that not even his wife could scratch, as intimate as they were. He loved mares, and there was no longer any other for him in his eyes. But the scratching of this itch would require a stallion.

In his youth he was far less careful, swinging fast and loose whenever he would go off gallivanting around. Before he met Cadance, he relished blowing his load in or on any mare he could get. But then there was another part of him, significantly more feminine, that wanted to be the mare, roughly used by whatever stallion would take him. This part of him loved being taken, being dominated by a rock-hard pony. Just the thought of submitting to that base desire to be filled and serve as an object of gratification would get him dripping with pre.

By now though, his career and his love life were so thoroughly complicated that he could not afford to be sloppy when he went trawling for cock. No, the sloppiness always came much later in the night, after draining the nuts of a couple stallions. He couldn't scratch that itch because it was deep in his ass, and the only balm that would soothe him was hard, throbbing dick.

In a trance-like state, he retrieved the special kit he now kept prepared at all times: gracefully, yet hastily, transforming himself. All that mascara, eyeliner, lipstick, edible glitter, scented oils and perfumes served to metamorphose a once proud Captain of the Royal Guard into the dainty and quite ladylike Gleaming Shield. The infrequency with which she got to satisfy this other side of herself made these nights all the more special.

She always felt so much better when she got all her makeup on. She was beautiful, and the sensation of a new dress and silky lingerie upon her bare skin was so sexy. And, just in case things got heated too quickly for her to 'prepare' herself properly, she lubed up ahead of time. This way, she avoided the quite unpleasant feeling of a stallion going in dry. That lesson in pain was taught to her a long time ago, when she first started identifying as a mare on nights just like this.

In time she developed a taste for pain during sex. Truthfully she luxuriated in the sweet torment of being rubbed raw. But not this night. Tonight was going to be vanilla...nothing wrong with vanilla, per se. Sometimes a simple quickie with no muss or fuss was the perfect relief after a hard day being a man. She smiled inwardly, having been on both sides of that one.

She just hoped that there would be a bronco out this late she could buck. Rare was it that she came home empty-hoofed (or empty-assed, so to speak), though it did happen from time to time. The days after those dry nights were always torturous, lust compounding on lust, the only thought trying to figure out how to get pounded. No, she was the Crystal Cum-Catcher, her ass was that famous. Dry spells did not last very long, unless Shining Armor was called away on urgent matters of state.

Lucky for her, the streets were filled with ponies. Hearts and Hooves Day—or Week rather, here in the Crystal Empire where it took on the quality of a festival—meant that there was always something to do, and somepony to meet. She scanned the crowds, spotting a very special catch. She always harbored a fantasy about this one, but never once had the opportunity presented itself.

She knew the huge red stallion as her sister's best friend's big brother, Big Macintosh. She idly wondered just how big he really was, acknowledging the rumors that spoke to his immense girth, and she felt her anus quiver in anticipation. Oh Celestia, was this what estrus felt like? She wasn't truly capable of that technically, but felt the heat of desire rising up inside her. She wanted it bad: needed it so very, very bad. And she always got what she wanted. She smirked at what a spoiled brat she was, and yet that same cattiness often served her more as an asset than as a fault.

Sauntering over to the crimson behemoth, she admired his rippling muscles. She wanted to tear that yoke off him and just lick his perfectly chiseled, sweaty chest. She wanted to lick every inch of him, and she always got what she wanted. His reputation preceded him, however. To land this one, she would have to play it cool, take it slow, and be careful not to spook him. You'd think a stallion with such a towering column of meat between his legs would be a little more self-confident, but not Big Mac. His tacit nature made talking him up, and propositioning a buck in the hay, a Herculean task.

She licked her lips predatorily, mentally preparing to tease and flirt until he could resist no longer, and would take her savagely. Anywhere was fine, a hotel, an abandoned warehouse, an alleyway; she didn't care. That would come later. Right now she had the biggest fish of her life to catch, and she had to be that wriggling worm that would get him to bite. She wanted him to bite her so bad, just chomp down on her neck or shoulder as he rutted into her ass!

No. Not yet, can't get distracted. None of this would happen unless she kept it together. She has to be cool if she wanted to actualize this fantasy and turn it into reality. Slow burn, get him hot little by little, and then all at once. Oh, she was a practiced hoof at that, but despite years of experience this was the stuff of legends. He was an elusive prize even amongst actual mares, after all. But oh how they would turn green with envy if she managed to get him. They would be so jealous, imagining him packing her full with that cunt-destroyer of his.

"Well hey there big fella, haven't seen you around these parts before. Are you new in town?" She launched her first salvo, a tried and true opening, friendly but not pushy; flirty, but not clingy. Always open with a question, get them interested, get them involved, and make them a willing participant. So that stallion will want to buck you.

"Eeyup," he smiled politely, and said nothing more. His eyes said 'buy some apples,' but his body language said not a thing.

"In the Crystal Kingdom for Hearts and Hooves Week? I imagine business must be quite good, what with everypony out and about at all hours," she returned his smile. She received only a nod, not even a verbal response this time. C'mon Gleaming Shield, get him to open up, ask him something that doesn't merit a one-word answer. Get your head in the game, girl, stop thinking with your dick for buck's sake!

"I hope you don't mind me saying, but you're quite handsome! Oh, I bet all the pretty mares say that about you," she giggled. She saw his face turn a darker shade of red, and she knew she was making some good progress. Time to cast out that lure, so that she could tug his rod. Easy now, don't scare him off...this one isn't going to just jump in the boat. This one was The One, and he would make her work for it. He would make her earn every inch. But she wanted every inch, and she always got what she wanted.

"Aw, I'm sorry, I didn't mean to embarrass you. You just look so strong that I can't help but compliment your amazing physique," she smiled, dialing it back a little. Reel it in a little bit, just a little bit, catch his eye. He knows he wants it, but that message hasn't quite reached his brain just yet. Soon. Soon he will be yours. This was going to be a heavy lift, but not as heavy as when she would get to lift his sack up and lick his perineum. Keep your eyes on the prize.

"You know, I just love apples. Nothing quite like wrapping my lips around a big, thick, juicy one," she smoldered. That definitely got a reaction, as she heard him stifle a quiet choke, and she saw his jaw tighten, pupils dilating, eyebrows raised almost imperceptibly—very small details, which the untrained eye would normally miss. Not her eye, though. She saw all. She saw the bulging vein in his neck, subconsciously aware that his heartbeat was increasing. She was going to devour him, all right, and it was going to feel so good. C’mon, nibble baby, take a nibble, you know you want this.

"Mmm, all that sweet, yummy juice running down my face, I just can't get enough," she intoned, her voice husky. "You know what though? A lot of ponies spit the seeds out." Bait is set, c’mon take it. Take this bait. Bite, damn you. Bucking bite me, I love it.

"Oh- oh yeah?" Big Macintosh stammered. Oh yes, and you are about to find out firsthoof, you lucky colt.

"Not me though, I always swallow," she growled, that sultry inflection surely driving him wild with passion. She was growling for his cum, and he knew it. Did he know she would bark like a dog for him? She hoped he knew. She hoped he knew she would debase herself in every lewd manner his sheltered farmhand brain could imagine, and more. She would open his eyes to new realms of eroticism that would ruin him for every mare but her. She was in heaven. This was her element, and he was helpless to resist. She watched him crumble right before her eyes.

"Eeyyuurrgghh," he groaned, and she knew she had him hook, line, sinker. Oh, the thrill she felt when she heard that sound, the noise a stallion made when his stomach churned and his resolve finally broke. Her legs trembled with desire as she beamed with the success of another conquest. His eyes burned red hot with a hunger that screamed, 'I WILL FUCK YOU TO THE CORE.'

"I'd love to discuss this further with you, later, when you've closed your cart for the night," she licked her lips again. She could afford to be a little more forward now. He was hers, they both knew it. "When do you...get off?" She emphasized that phrase, a seemingly innocent question if not for the implication behind it: that she would get him off in about ten seconds flat.

"Just closed," he rumbled, "I will go, and you must follow." He was a stallion of few words, indeed. She admired his flank as he pulled his cart back to a small hotel off one of the main avenues constituting the snowflake-like layout of the city. The thought of those flanks, those hips, thrusting powerfully, driving his dick deep into her ass, flashed through her mind. There were butterflies in her stomach, and hopefully soon there would be a hefty amount of jizz as well.

His hoof shook as he lined the key up and unlocked the door, opening it with a hard shove. Such unbridled power, he could have torn the door off its hinges with the amount of adrenaline surging through his body right now. It was all he could do to resist shattering the door into an explosion of splinters and a powdery mist of sawdust.

Once she was inside the room with him he slammed the door shut, shaking the wall, even the very foundation of the hotel itself. She had a feeling that the Crystal Empire was about to experience a localized earthquake. He turned to her, eyes ablaze, licking his lips with unabated desire. She rushed to him and started kissing and licking him everywhere she could; his face, his neck, his chest as he slipped off the heavy yoke and dropped it to the floor with a loud thud.

His hooves and teeth were rough, and tore at her dress savagely. The garment shredded easily and hung about her fetlocks, dragging along the floor as they kissed madly and made their way over to the bed. He threw her atop the mattress, and she felt firsthoof that raw strength as she flopped onto the covers. Oh Celestia, he picked me up like a bucking rag doll.

She lay on her stomach, staring back at him lustfully, but also with just a hint of fear. A lot of stallions really liked that steamy gaze, and she had it down to perfection. She saw him grind his teeth and break out into an animalistic grin as he was instantly upon her, biting at her neck and shoulder, making her moan and quiver. She was jelly under him, this was just what she wanted, and it felt so good getting it.

He stood up and she turned, eyeing his rapidly hardening cock. Rolling her hindquarters onto the bed she lay facing him, and he stepped forward giving her unfettered access to his package. She breathed in deeply, his heady musk driving her wild as she started licking up and down his length. She lapped at the flared tip, eager to taste of him, and tongue-bathed his sweaty shaft all the way to the base of his sack. Not stopping, she lovingly took each orb into her mouth, rolling them around, before working her way further back and slathering saliva all over his taint.

He took a step back, and she slid her tongue forward along his dick until she got back to the head, tracing circles around his crown. She turned belly-down once more, flicking her tail to the side and offering up her ass for him to take. She felt his turgid prick rubbing clumsily against her flank as he mounted her, and was very thankful she wore her chastity belt tonight.

It made the whole conversation about why they had to fuck her ass so much easier. She wondered if Big Macintosh might be strong enough to tear the garment right off of her, but he was far too consumed with tasting her flesh to take time to debate the merits of bucking one hole or another. No, he just wanted to line it up and rut into her in a rabid frenzy, and didn't care how.

He gave her flank a forceful spank and her eyes went wide in surprise. That was going to leave a very odd bruise that she hoped Shining Armor wouldn't have a lot of difficulty explaining away the next day. That momentary distraction was when he struck, dominantly sliding his shaft into her. His first stroke slammed into her so deeply that his medial ring pounded against her anus. She wailed with delight, wanting his neighbors to hear how hard she was being reamed.

This was paradise for her. Big Macintosh's weight bore down upon her, a titanic powerhouse of rippling sinew, furiously plowing into her with reckless abandon. She mewled greedily, eager to get stuffed and filled with his virility. Nothing felt this good in her life. At the back of her mind Shining Armor was protesting, trying to argue in favor of Cadance's tight snatch, but she was deaf to it. The only things that existed right now in her entire universe were that veiny bulging meat-drill, and her supple asshole milking it like the sleeve of a velvet turtleneck.

Big Macintosh was a whirlwind of intensity, his mind wholly consumed in the throes of a delirious fever, and the only prescription was more and more of her luscious jiggly ass: to be administered in a vice-like death-grip around his fat cock. He lost himself completely, hips crushing her pelvis with each vigorous plunge into her fuckhole. They were intoxicated completely with lust, a maddened trance taking possession of their bodies and spurring them on to new heights of euphoria.

Oh Celestia, she only felt this much joy when she was being ravished; completely giving herself over to servicing a strapping young stallion's steely member. She whimpered under him, his taut belly rubbing against her back as he unrelentingly decimated her tail-hole. He let out a mighty howl as his thrusts became increasingly ragged, building to that rapturous crescendo that shook her to her very center. With a final shove he buried himself balls-deep in her ass, and the stillness was palpable as he finally unleashed a torrent of cum.

They moaned exultantly, his legs shaking as he gave her a few more half-hearted pumps, emptying his heavy load into his newfound cum-dump. His chest heaving, he shook his head and breathed in the smell of sex deeply, his slowly deflating cock sliding out of her slick passage as he collapsed onto the mattress alongside her.

Within moments she was up on all fours, turning around to pounce upon him anew. She lapped hungrily at all the seed still clinging to his pulsing prick, whining as she slurped it all up and gulped it right down. She was an unabashed jizz-dizzy cum-whore through and through.

Tomorrow morning, Shining Armor would awaken to a familiar taste in his mouth, embarrassment washing over him as the realization of last night's follies fully struck him. That feeling of embarrassment would double as just thinking about it made him hard, and he knew tonight would be a repeat performance.

Silly Shiny, I always get what I want.

"Dear Diary: Today I Learned..."

Running the Crystal Empire kept the two lovers very busy. Princess Cadance was always meeting with somepony or another. Shining Armor also had his fill of duties to attend to: between training the Crystal Guards and doing border patrols, he often had little time for himself. Today was peaceful by comparison however. Idle hooves...

When had he walked into their bedroom? Lately he felt out of sorts when nopony else was around. Like he wasn't in control of his own actions. The feeling was very unsettling, what with his past experience on the receiving end of a hypnosis spell; compliments of a changeling queen. He caught something out of the corner of his eye, and moved to investigate. The corner of a book was peeking out from under the bottom dresser drawer. The same drawer with the hidden bottom panel where he kept his beautification kit, for the times he would transform himself into a mare of the night. He pushed the thought from his mind quickly, and picked up the book with his magic.

On the cover was simply the word 'Memories.' A diary? How odd. It wasn't Cadance's though, unless she was keeping a second, secret diary. He opened it and began leafing through the pages, randomly. What he read shocked him: it was erotic literature! Written from the perspective of a young mare, there were "entries" instead of chapters, each one brimming forth with detailed accounts of various sexual acts. It couldn't possibly be a real diary, because there were no names, no friends, no landmarks: just page after page of sodomy. Still it was pretty arousing stuff, and he worried that perhaps he'd stumbled onto one of Cadance's romance novellas.

Well, since I'm here, and I'm turned on with nothing to do, I could just rub one out, he bit his lip as he tried rationalizing jerking off in the middle of the day. His schedule wasn't exactly full of free time. He had things to do, ponies to see. Not right now, though. It won't take long. He quickly listed the pros and cons in his head, but with some chagrin decided he preferred taking the risk of getting caught over trotting around all day with sex on the brain.

Sitting down and starting to rub himself languidly, he turned back to the first entry in the book and began skimming. Early in the book was an unusually large number of visits to local glory holes. He nodded in approval and his strokes became a bit deeper, a bit faster. Flipping ahead there seemed to be a hoofful of pages missing. He stopped, and examined the other dates before and after the ripped out section. Their dates going back a dozen entries forward and backward in time had been violently rubbed out, as though the author didn't want to leave any clues behind.

This is not Cadance's, he thought to himself, I don't think it's a romance novel either. This is definitely somepony's diary. A chill went down his spine. He started reading more intently, trying to pick up on any details that would identify the owner. Flipping ahead again the entries became increasingly smutty, the depictions of stranger and kinkier sexual encounters becoming more and more verbose. One particular section jumped out at him.

Dear Diary,

Today I learned that stallions really like it when you lick them between their balls and asshole. I also learned about myself that I really, really like licking them in that spot. I mean, I like rimming them, and I love sucking on a fat sack of nuts, so you'd think that licking neither wouldn't be as good, right? But it totally is!

I don't know that it's better than giving a rimjob, I mean really it's just different. But it does make me feel kinda tingly when I do it. It's just fun, what can I say? I like it, perhaps mainly because of just how much they seem to enjoy being licked there. Basically that whole area from the dick down to their butthole is just one big yummy spot for me to drag my tongue all over.

I wonder if I'd ever get somepony to lick me like that I wonder why some ponies are so hesitant to let me lick them down there. I mean I tell them it will feel good and it's like they don't trust me. They should trust me, because I know what I'm talking about, and so they should let me lick their assholes and just shut up about it.

Haha, I'm actually getting a little horny writing this right now, you'd think I'd be satisfied after taking two stallions' meaty dicks up my ass tonight. And at the same time no less! Ugh, that feeling of being filled up, I just love it, can't ever get enough. Oh, Celestia, do I love that feeling of fullness when some stallion has his whole fat dick crammed up my ass, balls deep. It's the only time I really feel like a mareIt's that time that I feel like it's my destinyI kind of feel silly to say that, cuz I kinda sound like a slut <—You know what, just disregard all this for now.

Of course, it was fun even when they were just spit-roasting me, cuz I love to take a big thick dong down my throat and feel a big gruff stallion pumping his nutty seed down my throat. Not better, just different, like I always say! Ah well, I really have to end this and get back, so ta-taa for now!

Kisses~

Shining Armor stared in amazement, a little ashamed at how hard he was after reading that passage. I'm starting to wonder if this isn't a sex manual after all, Shining Armor idly thought.

The style of writing itself seemed to slowly change as well. The penmanship now was flowery. Flipping back to the start it was quite different with sharper, more disciplined calligraphy, like that of a colt practicing at hoof-writing. Did somepony else take over halfway through?...No, no it's definitely just a softening of style, I guess. It didn't make sense. But the most dramatic shift in style did occur right after the break where those pages went missing...

"Ooh, what are you reading, honey?" Cadance's soft voice broke him from his concentration.

"Nothing! It's nothing—" he sputtered as he dropped the book, revealing his still throbbing erection.

"Aw, you don't have to keep yourself from me like this sweety," she said softly, picking up the book with her magic and gently fondling his prick, giving it a gentle squeeze as she pecked him on the cheek. "Let's see what's gotten hubby so hot and bothered," she said with a sultry giggle as she sat down next to him.

The smile was gone from her lips the second she started reading the obscene tome. She stopped stroking him, then after a minute started up again in earnest. She blushed as she stumbled onto a particularly risqué passage. Suddenly realizing she was jerking him off, she ceased her ministrations and turned to him. "Where did you get this?"

He couldn't lie, but what could he say when the truth was barely an answer? "I found it in our room," he croaked hoarsely, his mouth dry. How'd it even get in here though? She didn't bring it in here and neither did I, so...does that mean somepony was in our bedchambers earlier? And dropped their diary? Yeah right Shining. Still, why is this book here? Did a guard slip it into our room as some sort of prank, maybe to embarrass his sister or something? Just seems so unlikely...

She turned her attention back to the foul text and quickly checked the front and back covers for information about the publishing house, finding none. "This is somepony's diary," she surmised, coming to the same conclusion that Shining Armor had mere minutes ago. "Not mine," she added hastily, Shining nodding enthusiastically and sporting a trusting look. No, he knew in his heart it definitely was not Cadance's, although he couldn't express what made him so certain.

She stood up and wandered off, still reading, the only sound her hooves pacing across the thick carpeting and the occasional turn of a page. He sat there, still hard, wracking his brain for answers that would not come. It barely registered in his mind when he heard a soft click as his wife locked the door, and the muted thud of leather against varnished maple. When he turned to look at her she was standing in front of him, face flushed. "Bed, now," she ordered huskily.

His look of apprehension quickly turned to an excited grin as he rocketed into bed, Cadance in hot pursuit. They collapsed onto the sheets and started kissing and nipping at each other, wrestling playfully for dominance. Shining Armor smiled triumphantly, watching his wife coyly feigning surrender, but she deftly swept his legs out from under him and he toppled to the soft downy pillows below. He was halfway up again before he noticed she wasn't trying to make a play, so he merely leaned back and they kissed passionately, tongues writhing against one another.

Cadance moved a hoof down to idly stroke his growing cock as it emerged from its sheath, giddily whispering for him to do her face-to-face. He straddled her with an ease borne from many hours of long, sweaty practice. He rubbed his dick against her tight, wet slit, getting himself partially lubed up with her own juices before lining his prick up and slowly sinking into her soft folds. He sighed in pleasure when he got halfway in, and couldn't help but moan when he bottomed out shortly thereafter. Beneath him, Cadance echoed his moans and bit her lip, writhing under his weight as he started sawing his cock in and out of her sopping cunt.

The sensuous lovemaking rapidly devolved into fevered rutting, Shining's pace quickening with each thrust, feeling his loving wife's tight hole quiver and flex around his throbbing girth. The two bucked wildly, aching for a quick release before somepony noticed their absence and came looking for them. Cadance moaned and arched her back as she came first, her pussy convulsing around her devoted husband's fat cock.

Shining grit his teeth in a half-smile as he looked down at her face as she came, her mane matted with sweat, and sensed his own climax fast approaching. He hilted himself with one final thrust and painted her walls with jizz. Panting with exertion, the two enjoyed mere seconds of post-coital bliss before a round of frantic knocking at their bedroom door interrupted any thoughts of a second round.

One badly-needed bath later, Cadance was off to greet a contingent of dignitaries from some Celestia-forsaken corner of Equestria. After cleaning himself off, Shining Armor wandered the palace halls, his hooves slowly and unwittingly retracing last night's steps. In a daze he walked out of the crystalline castle's doors and down the street, right toward Big Macintosh's apple cart. Blinking a few times he suddenly blurted out, "Wait, what am I doing here?" Nopony answered him, but he spotted Big Macintosh looking right at him. With more than a little apprehension, Shining Armor watched as Big Macintosh started slowly walking over to him.

Shining Armor busied himself at an outdoor curio stall, examining decorative spoons, while a strange sense of dread began to creep over him. It yelled for him to panic and run as fast as he could. Just as he was about to bolt, Big Mac was next to him. The two stallions looked at each other using only their peripheral vision. Big Macintosh turned to face him, and his face is very close, so close that Shining Armor could hear him breathing. He even heard him sniffing at him, and then just three words in his deep voice that made his blood curdle. "I know you."

"I'm sure you're mistaken, I would remember meeting you if I had," Shining Armor replied, flashing an innocent grin. Would I remember? Lately there have been so many foggy spots clouding my memory, like after a night of one too many hard ciders.

"Nnnnope, there's no mistake. I smell lilac and jasmine on you. And the subtle hint of my own musk on your breath," Big Macintosh's deep voice was quiet. Shining Armor's eyes were wide with terror, it was all he could do to keep from trembling and just continue smiling, lest somepony recognize him and intervene. He wanted so badly for somepony to help, but not the shameful embarrassment that would assuredly follow.

Big Mac glanced around furtively. Confident that no one noticed them talking, he prodded Shining Armor down a secluded alleyway. "What—wh-what do you want?" Shining Armor stammered, his back up against the wall.

"Turn around," Big Macintosh brusquely snarled.

"Why?"

"You know why, now turn around."

"No, please don't, not like this..." Shining Armor practically sobbed.

"TURN. AROUND." Big Macintosh's eyes flashed as he bellowed his command.

Tears welling up in his eyes, Shining Armor dutifully turned around and got on the ground. Immediately, Big Macintosh was upon him. Shining Armor clenched his eyes shut, bit his tongue to keep from screaming when he was penetrated, letting only a soft whine escape his lips. His vision faded into a white fog. Suddenly he was alone, and everything was a bright mist around him.

He heard voices up ahead of him, and as he approached there were his sisters, Twilight Sparkle, his Little Sister Best Friend Forever, and Gleaming Shield, his Big Sister Best Friend Forever. "Gleamy! Twily!" He shouted happily and trotted over to them. The three embraced in a group hug.

"I'm not interrupting anything, am I?" Cadance laughed, sneaking up behind him. She and Shining Armor nuzzled affectionately. "I'm just here to pick up Twi for our playdate, I'll leave you two alone," she winked at him, and with that disappeared with Twilight into the haze.

Alone, Gleaming Shield turned to Shining Armor and smiled. "I want you to know that I'll always be here for you," she purred, and caressed his cheek with hers.

There was a boom of thunder and abruptly the fog surrounding them turned red. He heard another boom, this time somepony yelling, "YEAHHH!" He turned around and there was Bulk Biceps, his body rippling with muscles. It wasn't supposed to be like this. Did he do something wrong? The mists spun like a cyclone and parted as his memory flashed back to that night, a stall door materializing between the two, quickly getting kicked down.

"Whoa hey easy now, just get back on the other side of the glory hole, everything's fine," Shining Armor tried to calm the big white monster down. Bulk Biceps was on him in an instant, pinning him down under his massive weight. "No, please don't, please, not like this. I like mares, I like mares," he whimpered in protest, but it was no use. Bulk Biceps lunged forward, and Shining Armor was pierced. He yelled in pain and sobbed, calling out for somepony to help him.

To his surprise, Gleaming Shield appeared. "Take my hoof, and it will all be okay," she calmly told him, her hair whipping around her face in the flurry of fog and wind.

"It…it hurts," he cried, and reached out to her. The second that their hooves met, the pain was gone, and he found himself staring down at her being pounded by Bulk Biceps instead in his place. He shook his head in confusion, trying to deny what he saw. She was being rutted fiercely and it clearly hurt her. But behind that mask of pain her eyes were glazed over with lust, and he saw she was bucking her hips back to meet each thrust.

"No…NOOO!" Shining Armor screamed, and ran from them with tears streaming down his face. Gradually the red mist softened to pink, and then white, and still he did not stop running. The white mist eventually disappated as well, leaving him alone in a dark void. Panting, he finally stopped and collapsed, shaking and crying. He held his eyes shut tightly and passed out, escaping into a sanctuary of oblivion.

Gleaming Shield's eyes snapped open, and she was surprised to find herself getting drilled in a seedy alleyway. She looked behind her and there was Big Macintosh, from the other night. How did she get here like this? This is very unusual, she thought to herself. She tried to reach out to Shining Armor, but there was no answer. She felt his presence faintly in the back of her mind, as though he were in a deep slumber. Very, very unusual.

Big Macintosh was still going at it however, and she quickly found herself getting turned on as well. She started shoving her hips back to meet his thrusts, because that was familiar to her—a rote habitual action that made her and this scenario feel much more normal.

"Unf, now you're gettin' into it," Big Macintosh panted gruffly above her.

"Mmm, yeah baby, like that," she cooed, rotating her hips in small circles as she squeezed around his length. Doing it in the middle of the day was risky enough, and in public even more so. She had an inkling that Shining Armor would want to leave as soon as possible, so she quickened her pace, trying to just milk the big stallion off in her ass before somepony caught them.

It worked like a charm, and Big Mac found the sensations overwhelming, quickly being driven over the edge. With a long drawn out 'eeeyyyuuuppp,' he lurched forward and flooded her ass with his hot cum. She basked in the afterglow of another successful conquest, brimming with pride and self-satisfaction. If it was possible for her to have her own cutie mark, she would have long ago expected to get one that depicted a wet and dripping cum-rag.

Big Macintosh got up and wiped his cock off along her flank. "I'll be seein' you again later," were his parting words as he trudged off. She sighed, and wondered why she had a thing for the strong, silent type. Oh right, it's because I love it when they use me like that, she thought inwardly, with a smirk.

Now though, she had to get cleaned up and back to the castle. Leaving the alley from the other side, she worked her way outward through the side streets until she was in the fields. Finding the river that flowed down from the Frozen North, she washed herself in the chilly yet refreshing waters. Can't show up at the castle without taking a proper bath, and I can't show up at a bath house or a hotel where I can get properly cleaned when I'm still dripping with cum, she huffed, shivering as she submerged herself in the frigid currents.

"Sir, thank Celestia we found you," a guard barked as he trotted up to the still-bathing pony, along with two other guards in tow.

"Yep, just out for a swim," she chirped, smiling back at the small group. Remembering herself she quickly corrected herself, "Uh, that is some clumsy pony spilled salad dressing all over me, and I was just washing up," she intoned, trying to make her voice deeper. What am I doing, why did I do that?

The guards exchanged strange glances, "Uh, Sir?"

"Go, I'll be back at the castle shortly," she said firmly, and the guards saluted her before quickly trotting off. Reaching out with her mind again she called to Shining Armor, and again she was met with silence. Oh Shining, where are you?

Having given herself the best washing she could muster without any soap, she made her way back to the castle. She rushed past numerous guards, aristocrats, and Prince Blueblood on her way back to her room at the heart of the palace. She idly wondered if Prince Blueblood was any good in bed as she pushed open the door and bumped face-first into Cadance wearing some lacy negligée.

"Oph, watch it there," Cadance giggled, "I thought it would be a nice surprise if I went ahead and cleared our schedules for the rest of the evening, so...ready for round two?"

"Oh, I would but uh, I really need a bath right now, because of all the salad dressing," Gleaming Shield mumbled, trying to deflect her. Met with more than a little confusion, she belted out several more lies rapid fire on top of her already farcical story.

"Geez, how much salad dressing could have possibly been spilled on you?" Cadance asked incredulously. Gleaming shield responded with something that sounded like, 'about a gallon,' before slipping into their private bath and locking the door behind her. She got a little carried away though, and didn't finish washing and pampering herself until three hours had passed.

Slipping back into the dark boudoir, Gleaming Shield quietly snuck over to the bed, hoping not to awaken Cadance. As she gently lifted up the corner of the satin sheet and slid under the covers, Cadance turned to face her, eyebrow raised. "All clean now, loverboy?" She asked with a sultry grin. Gleaming Shield was at a loss for words, having never slept with a mare before, or even felt so inclined. Neither pony was to blame, for how could Cadance know that it was Gleaming Shield sharing her bed, wearing her husband's skin?

Cadance leaned in to kiss Gleaming Shield, but was unexpectedly jilted. "Sorry to turn you down like this Cay, but uh, I'm still just really tuckered out from earlier," Gleaming said, hoping her feeble excuse might get Cadance to back off. "Maybe we could...just cuddle?" Damn it Shining, don't make me do this to you, don't make me do this to her.

Cadance embraced her husband tighter, and finally Gleaming Shield relented a small measure, kissing Cadance on the forehead, the neck, anywhere but the lips. I will not kiss my sister-in-law on the lips for you Shining, I just won't, she thought sternly. Cadance would not be denied, and the 'playing-hard-to-get' routine only served to increase her lustful requirements. Finally with much chagrin, Gleaming Shield settled into familiar territory: giving pleasure to a pony in need.

She had to try, because again it was the only way for her to make this situation approach anything remotely normal for her. Fiddling around with her privates, Gleaming Shield grimaces in disgust and shame. She can barely muster half-mast, but it's enough for Cadance to straddle and ride roughshod. Cadance humps into Gleaming's cock with wanton lust, trying to satisfy the ache that only increases as she senses her husband's inability to fully get it up.

"Shiny, are you okay?" Cadance asks with concern, and is met with a mumbled reply about not feeling well. But when she places a hoof to Gleaming Shield's forehead, she doesn't detect a fever. "I'm sorry, I just feel really out of sorts," Gleaming explained without going into any further detail. Cadance rolled back onto her side and the two of them drifted off to sleep in each other's arms, unsatisfied.

During the night, Gleaming felt Cadance rubbing up against her. Cadance was trying to get herself off, gyrating against her husband's still somewhat engorged member, her needy pussy slurping against the veiny length, her clit pressing hard into his shaft. Cadance's body shudders as she's brought to orgasm, and Gleaming Shield realizes with a tinge of sadness how close Cadance must have been earlier when they stopped. She frowns, but kisses Cadance softly on the forehead and hugs her tighter. With a mumbled, "I lovyuhhh," Cadance falls back into peaceful slumber.

Gleaming Shield finally dozes off as well...

You've gotta stop saving my rump like this. It's starting to get embarrassing.

In Dreams...

Gleaming Shield looks around: she's in the street surrounded by stalls of fresh fruit. The sky is black as night, but the ponies in the street are illuminated as though by the noon-day sun. She walks forward, looking around pensively, not sure of why she's here. Then she feels a presence. It's very weak but she recognizes it instantly as Shining Armor. Running around a corner, ducking down an alleyway, she finds him.

He's still trapped in time in that moment when she took over for him earlier the previous day. He and Big Macintosh are two granite statues locked in eternal embrace. Big Macintosh ruts into his ass furiously, foaming at the mouth, and Shining Armor lies piteously beneath him, his face a frozen mask of pain.

She feels inchoate rage boiling up from deep inside her, and with a surge of speed she spins around and gives the stone farmer a powerful kick with both hind legs. The head of the statue and most of the shoulders are knocked clean off, crumbling on the cobblestones below.

Haltingly the statue begins to change, from granite, to clay, and then finely packed sand. Shining Armor too changes in much the same way, from granite, to clay, and then flesh and blood. She pulls him from under the sand sculpture, watching as it collapses, the fine grains scattering on the winds. She picks him up and carries him out of the alleyway and around the corner, the streets now morphing from that of the Crystal Empire's to those of Canterlot.

With a few steps more, they're in front of their parents' house. As she steps through the door Gleaming Shield notices Shining Armor is much lighter now, transmogrified back into a very young colt. She herself is a young mare, about the age that Cadance was when the two first met.

She carefully carries him up the stairs to the bathroom, where she draws him a nice warm bubble bath. Placing him gently in the tub, she begins scrubbing him softly and singing a song their mother used to sing when she would bathe him. Shining Armor finally opens his eyes, and when he looks up and sees Gleaming Shield, he breaks down and cries.

"I wasn't strong enough, I was never strong enough," he whimpers, and she fights back tears herself as she consoles him.

His mother appears at the doorway, and she rushes in with concern. "What happened to him?"

"He and another boy were...playing in the street and...he got hurt," she lies, piecing together a plausible story as she goes.

"And just where were you?" Shining Armor's mother's question bounces around the inside of the bathroom like an echo inside a vast cavern.

"I wasn't there," she shakes her head. This is my fault, she laments, stepping aside as their mother comes forward.

"Wahh-maa," the young Shining Armor sobs, and his mother leans down over the rim of the tub to hug him.

Gleaming Shield stands dumbfounded with guilt when Cadance shows up, perky as can be. "Any room for me?" She chirps, and when Gleaming Shield looks back to Shining Armor and his mother they are both in the tub, and he's now the same age as Cadance and herself. Cadance gets into the oddly-expanded tub and the two mares hug Shining Armor tightly, and he's smiling happily, playing with a rubber ducky.

He gets out of the water and dries off, giggling as he runs out of the bathroom. Gleaming Shield follows him out the door, and they're in one of the hallways of the palace. She follows the trail of water around a corner where it stops. She blinks and looks down at herself, now inhabiting Shining Armor's body. In front of her is a shape that can't decide if it wants to be Twilight Sparkle or Gleaming Shield.

Shining Armor just stares at her, stunned. Flash Sentry approaches from another doorway and he smiles at Twilight/Shield. She smiles back at him, and the two lean in to kiss. Shining Armor's body propels itself forward, knocking Flash Sentry to the floor and strangling him brutally.

"Shiny what are you doing?" Flash Sentry screams in Cadance's voice. Shining Armor stops, bewildered, and in that moment Flash Sentry strikes, punching him right on the bridge of the nose. The entire world screeches with the sound of hooves scraping across a chalkboard as it's rent to pieces around him in hot red and white streaks of disconcerting pain.

"Why were you choking me?" She shrieked at him in a panic, hurling pillows in every direction as she stumbled out of the bed.

"I was having a nightmare," he offered up hesitantly, holding a hoof up to his bleeding nose.

"Well I'd certainly hope that you were!" She wailed as she ran from the room sobbing. A guard quickly rushed into the room to investigate the commotion.

"Please, go, I'm fine, just go make sure Cadance is looked after," he mumbled dejectedly as he dismissed the guard, levitating over a nearby handkerchief to wipe the blood from his face. He covered his face shamefully, distraught at having assaulted his wife while asleep. He wondered what could have gotten him in such a state. The last thing I remember before waking up I was...wandering the street? But that was in the middle of the day! Where'd all those hours go, what happened that made me lose half a day...or perhaps even more?

He closed his eyes and shook his head, breathing deeply to calm himself.

"Shining."

His eyes snap open. The room is much darker now, and he is not alone. Next to him in bed is...Gleaming Shield.

"Shiny baby, we need to talk," she says, a hint of sadness in her voice.

"Oh, Gleamy, I haven't seen you in..." he trails off as cheerful recognition gives way to the realization he's never seen her with his own eyes. Only imagined her, really; and a chill moves through the room.

"Yes, this is all new for me as well. Lately there have been some very strange occurrences. The way I manifested yesterday was not normal for us," she frowns, "And I know it's partially my fault that I wasn't there quick enough to...protect you."

"You're telling me that something strange is going on? Because I've been finding myself with holes in my memory for awhile now—mostly of nights when I couldn't sleep—and I often go places completely unbidden of my own conscious thought! Do you have an explanation for any of that?" He asks angrily, but he softens on looking at his double's apologetic demeanor.

"I'm sorry, but I don't. I vaguely recall that when I first began to exist, you needed me for...well, to 'shield' you from...shall we say, certain aspects of your own behavior. Behaviors that your mind didn't know how to handle. I took on only what I needed to, and became only what you allowed me. Gradually that grew and shifted to encompass a wider range of...activities."

They exchange knowing glances. "So, why do you exist?" Shining Armor asks abruptly. I think we both know it's because you get turned on by other stallions' cocks, the thought runs through both their minds as one. "Oh Celestia, why me?" Shining Armor sniffles, existential dread wracking him to the core. He starts hyperventilating, his breaths coming short and ragged as Gleaming Shield reaches over to rub his shoulder.

"There, there, it's perfectly normal. Well, it was perfectly normal, at the start. Now, though..." she trails off, unsure of how best to continue. "Maybe we should ask our sister for help with this?" She asks quietly, and if Shining heard her, he doesn't acknowledge the question or the implications that come with it.

"I just don't know what to do here, this is completely bucked up beyond all recognition," he shakes his head, staring forward at nothing.

"I have an idea," Gleaming Shield suddenly says with a smile, trailing a hoof up his broad chest. She straddles him, their thighs rubbing together, her limp cock juxtaposed against Shining Armor's now rock-hard shaft, both of them falling back on something they found 'normal,' at least to them.

"Wait, is this really the best idea?" Shining Armor asks with a raised eyebrow, summoning up a small trace of lucidity.

"Just trust me on this," Gleaming Shield coos, licking her hoof and giving his dick a few wet strokes before scooting up and positioning herself properly, rubbing his throbbing prick against her soft perineum and hotdogging his fat length between her ass cheeks. She leans forward and reaches behind to steady his cock, lining him up as she slides back and expertly takes him up her tight ass.

She moans with pleasure, blushing as she hears him echo her with a sigh of his own satisfaction. She looks down and sees herself, but still in the way that he sees her. "Shiny, do me one favor though. Here in this world, you still have control, not me. I want you to let me...be the real me, the mare I am inside. Can you let me be myself? Make me your mare," she asks, the faintest tears forming at the corners of her eyes, her body rocking back and forth gently atop his muscular form.

Shining Armor looks at her face and blinks, How am I supposed to do that? But as he watches, her features soften, and his eyes dart down to gaze at her cock rapidly imploding, folding in on itself and becoming a wet, winking cunt. She bucks into his hips again, exulting in her new form, riding him with her ass as she leaks all over his belly.

Her bounces come at a faster pace, her ass slamming down against his muscular frame, as she rides him to a squealing orgasm, spurting pussy juice as she clenches around his throbbing prick. He becomes overwhelmed as she milks his dick like a pro, and he soon empties his load deep in her bowels as well, listening to her cry out his name.

"Shining! Oh, Shining! Shining!"

Shining!

Shining Armor bolted upright in bed, a cold sweat beading on his forehead. It was still dark outside, but now it was Cadance next to him in bed, no longer Gleaming Shield. "Shining, I'm sorry, I was so scared when you...you know," Cadance said softly.

"Please forgive me babe, you know I'd never hurt you, I...I'm just so, so sorry for doing that," he reached to embrace her, and she winced as though still afraid he would strike at her again. When she saw the look of sadness and horror on his face at that, she hugged him immediately, sniffling into his strong chest.

The two settled down into bed in each other's arms and Cadance slowly drifted off to sleep. Shining Armor merely watched the ceiling, unable to find peace. Or perhaps unwilling to face what was waiting for him...

Shining, make me your mare.
