Swelling with Pride

"So that's how you get your mane and tail to shine like that?" Cadence grinned playfully at the larger alicorn, raising an eyebrow as well. "I figured it must have been some sort of magic. I never would have guessed it was so simple!" she giggled and brushed a hand through her own mane, getting a soft giggle from Celestia as well.

"Mm, yes. that's how I've always done it. Though, I suppose you could try what Luna does for her mane." Celestia replied, before levitating a teacup to her lips and gently sipping from it. "What she does is-"

"Your highness...es!" A guard hastily called out as he pushed the door open, entering the throne room followed by four other guards who were all carrying a large crate with their magic. "You have an urgent parcel...er, package, as you requested." he walked up to the small set of stairs just before the thrones, bowing gracefully while the other four guards approached and set the crate down in front of the two princesses. "We believe it is a majority of the goods that had been stolen during last week's invasion from the thieves' guild."

"Hm...very well." Celestia nodded, getting up to her feet as Cadence stared at the wooden crate, soon getting up as well. "Many thanks, my guards. Dismissed." she added; all five guards bowing gracefully once more before quickly exiting the room, closing the throne door behind them. Turning towards the crate, she gently pried it open with her magic, glancing inside. "I suppose our get-together must come to an end, Cadence."

"Heh, it's no problem." Cadence smiled and walked up to the side of the crate as well, glancing inside for a brief moment. "I know you've got a lot of work to do. Heck, finding the time was a bit of a struggle for me too!" she giggled softly again, before sighing a bit. "It gets pretty busy up there, sometimes."

"I can imagine." Celestia smiled back and nodded, before looking into the crate again. Her smile quickly changed to a more inquisitive look though as something caught her eye; the alicorn craning her neck down to get a better look. "Hm, what is this?" her magic aura surrounded a little green bottle inside the crate and pulled it up in front of her face. She squinted her eyes a bit to read the little label for a brief moment, before grinning wide. "Oh, hoho! I have not seen one of these in quite a while."

"Hm?" Cadence tilted her head a bit, looking at the bottle as well and raising an eyebrow again. "What is it, Celestia?"

Turning to glance at Cadence again, Celestia continued to grin playfully, levitating the bottle over in front of the other princess. "This lovely little potion has a very unique effect. One I'm sure you could find a use for." she winked to Cadence, who was now squinting to read the label as well.

"Huh...what kind of effect does this one have?" She looked back up at Celestia again, still a bit confused at the whole situation, though the other princess only giggled and leaned in closer and whispered into Cadence's ear, her confused look quickly changing into a playful grin. "Oh, my...that does sound lovely!"

"Mm, yes. I've got no doubts that Shining Armor will enjoy it." Celestia giggled softly while turning over the potion to Cadence's magic. "Perhaps something you could do with him next time?" she winked playfully to the other alicorn, still grinning at her.

"Of course." Cadence poked her tongue out a bit as she levitated the potion with her magic, before reaching her hand out and grabbing it. "I'm sure I'll find a wonderful use for this."

"Glad to hear it." Celestia nodded before turning towards the crate again, glancing inside it. "I suppose I'll let you go now, Cadence. Come back again soon, okay?" she smiled at the pink alicorn, who nodded with a smile of her own, before turning and heading out towards the door.

"Hee, Shiny is going to love this..." Cadence thought with an eager giggle as she quickly made her way through the halls of Canterlot castle, spreading her wings and taking off as soon as she was outside, heading up north towards her own kingdom.

"You want to...what now?" Shining Armor rubbed his chin gently, giving his wife a rather apprehensive look as the two walked through the castle corridors, heading up towards the guards' garrison.

"Trust me, Shiny. You'll love it!" Cadence giggled, gently cuddling against the stallion's side as she walked, wrapping an arm around his body and lightly rubbing his chest with that hand. "This is no ordinary potion, as I said. It will have effects that we've never seen before." she then blushed and smiled, gently patting Shining Armor's chest. "It just, heh...requires me to have some fun with the guards first."

Shining Armor's eyebrow remained raised as he looked at the alicorn once more, crossing his arms over his chest. "If you have a problem with how I'm treating you in bed, you can just say so."

Cadence only giggled and shook her head, cuddling a little tighter to the big stallion. "I'm doing this for you though, dear!" she smiled and nuzzled his cheek, giving it a soft peck. "I know it sounds weird, but I promise you'll love the results!"

"And why can't you just tell me what you're planning on doing?" the stallion replied, giving Cadence a bit of a flat-stare now.

"Because then it wouldn't be a surprise!" Cadence giggled once more as she cuddled against her husband a little tighter, wrapping both arms around him for a couple moments. "Trust me, it's going to be so much fun."

Shining Armor huffed softly, turning his gaze towards the large door in front of him, recognizing it as the entrance to the garrison. "If you say so..." he shrugged and pushed the door open, leading the alicorn inside the main hall of the garrison. "AT ATTENTION!" he shouted, his voice echoing through the various hallways the branched off from the main one.

Almost immediately, the sound of footsteps could be heard echoing back towards the main hall, and in less than ten seconds, six crystal guards had assembled in a perfect line in the middle of the hall, saluting towards Shining Armor.

"Ooh. That was faster than last time!" Cadence giggled softly, watching Shining Armor walk up to the line of guards and grinning playfully towards him. "Go on, honey. Tell them what their assignment for today will be."

Shining Armor blushed just a bit, shaking his head and sighing softly to the mare's command. "I can't believe I'm about to do this..." he softly grumbled, before looking over at the line of guards again. "My guard, your duties...egh, your duties for tonight will be to..." he stammered a bit, blushing a bit more now from the growing feeling of embarrassment.

"Well, honey?" Cadence grinned playfully as she cuddled against the big unicorn's back, lightly stroking her hands up and down his sides. "Tell your guards what their duties are." she teased, the guards getting a bit suspicious now, a few eyebrows raising amongst them.

"Your duties..." Shining armor groaned, shaking his head again. "Are to sexually please my wife in whatever way she asks you to." he finally managed to get out; all eight pairs of eyes in front of him opening wide in surprise.

"Mm, not as wordy as I would have liked, but I'll take it." Cadence giggled and pecked Shining Armor's cheek again, before stepping out in front of him, smiling at the row of guards. "You heard him, though. You lovely guards will have the honor of serving your princess in ways most stallions only dream of." she crossed her arms over her plump chest while her smile curled into a playful smirk.

"B-but, Princess Cadence..." One of the guards began, a good bit of blush forming on his cheeks as well. "You're married!"

"Hehe, I'm very glad that you're concerned for me, dear." Cadence stepped up to the guard in question, lightly stroking a finger upward from his chest to his chin, only causing him to blush harder. "Just because I'm married doesn't mean I can't have some fun with my royal guard. Besides..." she then brought her other hand up and slipped it into her cleavage, pulling out the same potion that Celestia gave her. "You are all just part of a lovely surprise for my husband."

"Princess, are you sure?" Another guard leaned forward just a bit to turn towards the princess; a bit more eager to accept her offer, but still suspicious of her request.

"Of course, darling." Cadence moved over to the other guard now as her magic pulled the cork out of the small vial in her hand. "I am hereby ordering all of you to pound my royal rump." she added with a smirk before putting the vial to her lips and drinking the small amount of liquid inside it.

At this command, just about all of the guards either blushed or grinned, or both; watching as the pink alicorn began to undo the various parts of her gown, the whole thing falling to her ankles as she untied the last part of it, leaving her in nothing but a lacy black bra and matching panties. "So...which of you wants to further undress your princess?" she teased with a wink, glancing down at the guards' waists and licking her lips a bit as she saw growing bulges in almost all of their pants.

Despite his feelings about the situation, Shining Armor couldn't help but stare as well, feeling his own stallionhood starting to slip forth from its sheath and harden. He watched as one of the guards eagerly stepped forward and grasped at the princess' bra, unclipping it and sliding it down her body; only grinning wider as he gazed at the two plump melons before him. Shining Armor bit his lip gently, his cheeks flushing red again, though his member only continued to stiffen up between his legs.

"Ooh, now that's what I want to see..." Cadence blushed a bit as well, smirking at the guard in front of her as she began to lightly rotate her upper body back and forth, causing her hefty breasts to jiggle before the guard's eyes. "Big, horny guards eager to violate their princess!" she giggled softly, reaching down and grasping the transparent cock between the guard's legs, giving it a couple teasing squeezes.

"Mmngh...I-I'll do...anything you wish, Princess Cadence!" the guard moaned softly in response to the squeezing; already throbbing against the soft hand and oozing a drop of precum.

“So glad to hear it, darling.” Cadence leaned in and gently pecked the guard’s cheek, giving his cock another soft squeeze before her horn glowed again, a decently-sized bottle of lube teleporting in right beside her, surrounded by her magic aura. “Your princess wants her royal rump to be lubed up nicely.” she winked to the guard, levitating the bottle into his hand before turning around in front of him.

“Y-yes...anything for my princess.” The guard grinned even wider, watching the alicorn slowly bend over forward, bringing her hands to her hips and sticking both of her thumbs into the edges of her panties; her head turning to the side to playfully smirk back at the guard as she slipped the garment down over her plump rear. The guard’s eyes followed it closely until it passed over those soft pink cheeks; the sight of Cadence’s now bare rump easily arousing him and the other guards even further, causing all of their erections to become almost painfully hard.

“Mmm...come on, my dear...your princess gave you an order.” Cadence giggled softly, still smirking back at the guard as she playfully wiggled her rear, causing the panties to drop to her ankles. The guard hesitated not a second longer, stepping right up behind the alicorn and working to get the cap of the bottle open; his eyes glued to the lovely pink butt before him.

Just as he was turning the bottle upside down though, the princess teasingly wiggled her hips again, causing those pink cheeks of hers to jiggle just enough for the guard to notice. “Hhhnnggh….” he bit his lip as his eyes widened, and at the same time, his hand squeezed the bottle quite firmly, immediately gushing almost the entire bottle of lube onto Cadence’s rear.

“Ah...oh my!” Cadence shivered softly and let out a soft moan as she felt the liquid splashing all over her, almost completely soaking her butt; some of it dripping down her legs as well. “Seems someone is quite eager.” she looked straight forward again, glancing at Shining Armor for a moment and seeing him sporting a full erection as well, licking her lips gently to the sight. “Just you wait, darling...you’ll get your turn.” she winked to him, before leaning back just a bit, pressing her lube-soaked rear against the crystal cock behind her, immediately hearing a pleased grunt from above.

“Ngh...princess…!” The guard gasped and grunted softly as his member was squished between the alicorn’s soft, buttcheeks, immediately gushing a glob of precum onto her lower back as it throbbed wildly. “Y-your butt is...magnificent!”

“Oh, come on, my lovely guard.” Cadence smirked back at the guard again, lightly pressing back against him over and over, rubbing her lubed rear against his cock to further tease him, enjoying the feel of it throbbing against her. “Surely you’d like to really speak your mind about your feelings for your princess' behind?”

“I, uh…” the guard raised an eyebrow, somewhat confused about what the princess had asked him, though her playful smirk clued him in somewhat. “It is...uhm...quite big...and soft, princess.”

Cadence only giggled and shook her head, pressing back a little more firmly against the guard’s shaft, making him moan softly again. “Is that all? Judging by how hard your cock is, I thought you would say a lot more than that.”

Still confused, the guard blushed a good deal, shaking his head softly as well. “I’m...afraid I don’t know what you’re getting at, princess.”

“Mm, you guards are certainly trained to be polite.” Cadence rolled her eyes, smirking back at the guard again as she pressed against his member once more. “Talk dirty to me, my dear. Really let me know how much you love my butt. Don’t hold back, let all of your feelings spill forth.”

"Ah...if you insist, Princess." The guard grunted softly as the princess' push back against his member coaxed out a sizable drop of precum, oozing down his shaft and between the two pink cheeks below. "Your royal rear..." he began, feeling a bit more confident now seeing the princess' lustful smirk, giving her a bit of a playful grin in return. "...has to be the biggest, fattest butt in the whole empire!" As he finished, he reached down and gently squeezed Cadence's soft rump with both hands, causing her to moan softly.

"Ooh, that's more like it...keep it up, darling. Tell me exactly how much you enjoy my big, fat butt." Cadence teased, wiggling her hips a bit as she felt the guard gently grab her, turning her gaze towards the other guards, who were still standing in line. "What are you all waiting for? Come over here and play with your princess."

With that, the other five all moved in front of her, standing in a semicircle, all of their erections standing at attention before the princess as well. "Mm, now that's more like it." Cadence licked her lips as she gazed at the five crystal shafts before her. Reaching out, she grabbed the two nearest to her, gently stroking along their lengths, while glancing at the guard directly in front of her, smirking up at him. "A little closer, darling. Your princess wants a taste."

Grinning right back at her, the guard eagerly stepped forward, presenting his member to the lustful princess. "Dirty talk, huh? Alright...suck it, you slutty princess." he pushed his hips forward a bit, pressing the tip of his cock against Cadence's lips as she blushed lightly.

"Mm, now you're getting it!" the alicorn giggled before parting her lips and engulfing the tip of the crystal shaft, suckling on it a couple times and swirling her tongue around the tip, causing the guard to groan out loud from the sudden shock of pleasure coursing through his cock. After that brief tease though, she took her mouth off again, turning to look back at the guard behind her, who was still just gently grinding against her butt. "I ordered you to pound my royal rump." she teased with a bit of a firm tone, pressing back against the guard's crotch again.

At this point, Shining Armor's lust easily overtook his mind; the sight of his lovely wife being taken by all of those guards at once turning him on beyond belief. One of his hands was already idly stroking his shaft as it throbbed and twitched in time with his heartbeat, while thoughts of taking one of the guards' places flooded his mind. Still, the lovely alicorn said she had a plan in mind, so he continued to eagerly wait. "Ngh...she sure does know how to tease a stallion..."

Meanwhile, the guard behind Cadence groaned from the light squeeze his shaft received, before he slid his hands up to the princess' waist and gripped it firmly, pulling his waist back a bit. "Here I come, you cock-hungry princess!" he teased, before thrusting his hips forward and penetrating the alicorn's snug backdoor, grunting a bit from the tightness while Cadence moaned out loudly.

"Mmnh, yes! Shove that crystal cock deep inside me!" Cadence groaned, her hands jerking the two stallionhoods beside her a little faster now as she leaned in towards the guard in front of her once more, opening her mouth wide and engulfing the head and first few inches of his shaft, suckling on it right away. Of course, not wanting to leave out the last two guards, she began to work her magic, her pink aura wrapping around half of the length of both their members. Immediately, those two pink auras began to move up and down, stroking the entire length; both guards groaning happily in response.

“Nggh...f-fuck...you’re so tight!” The guard behind her moaned, eagerly shoving his cock deeper and deeper inside her as it throbbed wildly, the constant gushes of precum lubing up that tight passage just enough for him to push inside without too much resistance.

“Mmngh, playing with six stallions at once...you’re awfully good at this, for a prim-and-proper princess.” the guard in front of her taunted, sighing contently as he enjoyed the princess' lips and tongue around his shaft, lightly bucking his hips against her just as the guards to her sides were doing. "Certainly better, ah...than any common mare that has serviced me before."

The sexual teases only served to further arouse Cadence; her pink cheeks slowly tinting red as she kept up her work; jerking four of the guards with her hands and her magic while expertly working her mouth on the crystal pole in front of her, feeling the tip of it bump against the back of her throat every time she bobbed her head. "Mmmpmhh..mmff..." she groaned around it as the guard behind her began to steadily buck his hips, thrusting his cock nice and deep into the princess' rear.

"Aahh, and she's way better...than any mare I've ever fucked!" the guard behind her moaned, both of his hands squeezing at Cadence's plump butt as he kept up his thrusting; the tight squeeze of that royal rear easily milking out more of his warm precum, only making his thrusts easier and faster. "F-ffffuck...I think I'm gonna have to hold back...I feel like I'm gonna blow already!"

Hearing this, Cadence's ears perked up, and she immediately stopped sucking the guard in front of her, only to smirk back at the guard behind her. "Mmnh, no...don't hold back, my dear." she spoke between her soft panting and moaning, licking her lips gently. "Your princess wants you to cum...as soon as you can!"

"Ngh, b-but princess..." The guard frowned, his thrusts slowing just a bit as he heard the princess' command. "I want to enjoy your-"

"That's an order." Cadence teased, pushing back against the guard again as her horn glowed a little brighter, her magic now fondling his balls as well, causing him to gasp from the extra bit of pleasure. "Your princess commands you to cum inside her ass!"

Blushing a bit as well, the guard kept up his thrusting once more, squeezing the alicorn's rump a little tighter. "Aah, yes princess!" he groaned, biting his lip gently as he felt his orgasm rapidly approaching, signaled by the more frequent throbbing of his shaft, along with the increased flows of precum. "I will cum inside my princess' tight ass...!"

"Oooh, that's more like it!" Cadence moaned as the guard picked up his thrusting, moving her head back and returning to sucking on the crystal cock in front of her, much to the delight of the guard it was attached to. Already, she noticed the other guards throbbing harder as well; both of her hands getting lots of precum smeared across them, while she slurped up a good amount of it as well. All the while, she kept working her magic as well, jerking the last two guards' shafts even faster.

Of course, with such a sexy sight before him, Shining Armor found himself cumming already, grunting softly as he jerked himself a little faster, blowing his load onto the polished castle floor in front of him, splattering it with quite a few streaks of white. "Aggh...d-damnit..." he groaned, blushing lightly as he continued to watch the guards and his wife, seeing the guard behind her leaning forward and bucking his hips even faster.

"Ooh, princess...I'm cumming!" he moaned, thrusting a few more times into the princess' snug rear before burying his entire length inside; his cock throbbing powerfully and releasing a gush of seed with each throb, filling the royal rump with warmth.

"Mmmmfff..." Cadence's eyes rolled back as she felt this warmth flowing within her. As the carnal fluids filled her, a powerful tingling began to well up within her butt, increasing more and more with each passing moment. Just as quickly as the guard started cumming though, the flow of seed slowed to a stop and the guard sighed contently, leaning back a bit.

"Ahh, that was awesome...your ass is amazing, princess." the guard smirked and squeezed Cadence's butt, though as he did, he raised an eyebrow and looked down at the pink posterior. He could have sworn that it was slightly bigger than before, but he simply shrugged and assumed it was his horny mind playing tricks on him.

Just as the guard began to pull his hips back, Cadence took her mouth off of the cock in front of her, panting a bit and licking her lips. "Mmnh..mmm...next!" she called out, grinning eagerly up at the guard in front of her. "Come on, stuff your princess' butt with cum!"

That order was all the guard needed; quickly moving behind the horny alicorn just as the other guard moved away. "Heh, here it comes, princess!" he teased, grabbing her butt just as the other guard did and eagerly stuffing his stallionhood inside, groaning blissfully. Being that the princess had been sucking him off a good while, he was already quite close to cumming, and with just a few moments of bucking, he felt his orgasm coming on.

"Ahh...ahh, yes...!" Cadence leaned her head back and moaned out blissfully again as she felt the second guard cumming inside her, filling her with another load of steamy cum, and once more triggering the tingly feeling within her soft rump. As the other guards moved away from her face and began to line up behind her, Shining Armor began to notice what his wife was up to now; his eyes watching that pink butt intently.

Just as the second guard stopped cumming, he saw the princess' butt swell slightly larger and rounder; his eyes widening a bit while his cock immediately sprung back up to attention. "So...that's what she wanted to do? Make her butt bigger with the guards' cum?" he found the idea quite strange, but very arousing nonetheless; his hand beginning to slowly stroke up and down his throbbing length once more.

Shining Armor continued to watch as the guards formed an orderly line behind the princess, each one thrusting into the swelling butt and blowing his load, before pulling out and giving the next guard a turn. "Oh man...she's really getting big..." he bit his lip gently as the fourth guard pulled out, Cadence's butt easily twice as big as normal, and only swelling even larger as the fifth guard grunted and pumped his spunk into the growing rear.

Of course, with such a massive difference, the last guard easily noticed, squeezing and squishing the two huge buttcheeks as he hotdogged his shaft between them. "Mmf, damn, princess! I've never seen such a fat ass!" he teased, giving the princess' cutie mark a firm slap, only causing her to moan seductively.

"Of course...mmnh, now keep filling it, so it can grow even fatter!" Cadence smirked back at the guards, licking her lips a bit as she pressed back against the guard's cock, feeling the tip of it prodding against her snug backdoor.

"You don't have to tell me twice!" the guard chuckled and squeezed at Cadence's plump butt again before thrusting his hips forward and burying himself balls-deep in the royal rump, letting out a blissful groan as the tight squeeze milked his orgasm immediately.

All the while, the princess' husband watched intently as that pink rear kept swelling and plumping with each load that was pumped inside it; the next guard thrusting inside just as the previous guard pulled out, giving Cadence a nearly constant stream of seed filling her up. "Sweet Celestia..." Shining Armor mumbled, still gently biting his lip as the last guard slowly pulled out; Cadence's butt now over three times its original size, incredibly large and plump, easily bigger than even Celestia's cake-plumped rear.

“Now do you see, darling?” Cadence glanced over at her husband now with a playful grin, reaching back and gently stroking a hand along her gigantic rump, feeling how soft and plump it had become. “I was simply preparing a gift for you in a way that would benefit your lovely guards as well.” she giggled and looked over at the six guards again, a couple of them sitting down from the fatigue of their afterglows.

“You could have just told me in the first place.” Shining Armor grinned now as well, chuckling and walking up to the fat-bottomed mare and embracing her, his hands both sliding down and squeezing at that giant butt while his stiff shaft pressed against the mare’s belly, still throbbing eagerly. “Though I guess a surprise is nice too.”

"A lot more fun than just using my magic, that's for sure." Cadence giggled softly and wrapped her arms around the stallion as well, letting out a pleased groan as her fat butt was squeezed; her own hands sliding down and grasping at her husband’s stallionhood, lightly rubbing it up and down. "Now it's your turn, my love.”

With that, the alicorn turned around and pressed back against Shining Armor, squeezing his member between those huge pink buttcheeks as they pressed firmly against his crotch. “Mm, go ahead, darling...enjoy your princess’ lovely butt.” she teased, blushing a bit as she playfully smirked back at the stallion, who was groaning softly from the softness encasing his twitching shaft.

“Mmngh...of course…” Shining Armor sighed contently and reached down, grabbing Cadence’s waist and firmly holding it as he began to lightly buck his hips, sliding his cock back and forth between the two massively plump buttcheeks. “This feels...ngh...even better than your boobs!!” he groaned, already feeling a bit of precum oozing forth as he kept up his steady thrusting.

“Is that so…?” Cadence couldn’t help but moan softly, feeling her soft rump lightly jiggling each time Shining Armor’s waist clapped against it, sending a light tingly pleasure through it. “Maybe we should do this, mmh, more often.” she teased, her blush deepening slightly as she looked forward again, seeing the guards watching her intently, some of them slowly rubbing their stiff shafts. “The guards certainly agree with me...heh…”

With his hands squeezing a little more firmly at the alicorn's waist, Shining Armor continued to eagerly buck his hips, hotdogging his twitching shaft a little faster now as the pleasure built up within him. "I feel like I could, ah...cum just from this!" he groaned, feeling more of his precum flowing forth, smearing into the soft, squishy heaven surrounding his cock.

"Go right ahead, darling...mm, give your princess a nice glazing!" Cadence teased, turning her head to smirk back at her husband again, seeing the pleased, yet focused look on his face. "Keep telling me how much you love it though, Shiny..." she winked to him, still smirking playfully while her horn glowed, starting to lightly stroke and fondle her husband's hefty sack with her magic.

"Aaahh...mmngh, if you insist, dear..." Shining Armor couldn't help but grin at the alicorn's request, while his hands slid down to her giant butt and began to squeeze it, pressing the soft cheeks together against his thrusting member. "Mmnh, oh yes...your ass is just so perfect...surely the biggest, fattest ass in Equestria!" he teased before raising his right hand, only to bring it right back down again, smacking the side of the princess' fat rump, causing it to jiggle quite a bit.

"Oooh...oh yeah..." Cadence moaned from the slap, sending more shockwaves of pleasure through her overplumped rear; her nethers really starting to moisten now from the prolonged teasing. "Keep going...mmnh...tell me more, darling..." she sighed blissfully, continuing to work her magic on Shining Armor's balls, returning the teasing pleasure.

'Heh...mm...not even Celestia's butt is this big...have you been getting into her cake, you naughty bitch?" Shining Armor continued to playfully tease, raising his other hand now and smacking the other side of the princess' rump, once more causing quite a bit of jiggling. With the magical teasing of his family jewels, he grunted a little louder, continuing to firmly thrust his hips against the giant pink butt, smearing loads of precum between the soft cheeks now.

"Mmnh, she has been giving me some, ahh...tips on how to get nice and plump!" Cadence blushed deeper from the repeated spanks, feeling that thick length throbbing harder against her soft butt and pressing a bit more firmly back against it. "I guess I'm, nngh...even better than she is."

"Damn right you are...ahh...and you're all mine!" Shining Armor smirked down at the princess as he continued to smack the sides of her oversized rear, causing quite a bit of jiggling, only helped by his hips clapping against the soft cheeks as well. "This plump, fat ass...all mine...to pound every single night!" he grunted softly, feeling the pressure in his loins building up more and more; his orgasm just moments away at this point.

“Oh yeeaahh…” Cadence closed her eyes and moaned lustfully; her husband’s words only further arousing her and increasing the moisture between her legs. Feeling the thrusting stallionhood throbbing harder against her soft rear, she began to work her magic against Shining Armor’s balls even more, stroking over every inch of the plump orbs to tease him further. “Cum for me, nnh...give your princess’ fat butt a nice frosting!”

"Nnghh, oh fuck yes!" Shining Armor groaned out loudly and squeezed Cadence's plump rear even harder, finally being pushed over the edge of his orgasm by the magic teasing below. "Cumming...ahh...!" he let out a blissful moan as the pressure between his legs finally released in the form of a thick stream of seed, gushing forth from his throbbing member and splattering all over the alicorn's giant butt and lower back.

With a pleased moan, Cadence lightly pressed back against the stallion’s shaft once more, feeling the hot loads splashing all over that massive rump of hers, almost completely coating it after just a few moments of the stallion’s strong orgasm. After a few more gushes of seed, the lustful stallion’s orgasm finally died down; lots of his seed dripping down Cadence's legs now from the sheer amount of it that had splashed all over her butt.

“Mmm...I take it my lovely guard captain enjoyed himself?” Cadence teased, glancing back at the stallion with a playful grin, while her cheeks continued to tint red. “You really frosted your princess’ royal rump…” she giggled softly, gently shifting her hips and rubbing that fat rear of hers against the stallion’s shaft, feeling it still lightly throbbing between the soft cheeks.

“Aahh...heh...even better...than a titfuck…” Shining Armor teased back between his soft panting, smirking down at the splatters of white that he had created. “Is that enough of a frosting for you, dear?” he teased, lightly shifting his hips back and forth to gently rub his shaft between the now very sticky buns.

"Hehe, it certainly feels like a big frosting." Cadence giggled softly, standing up straight again and leaning back against the big stallion, while her hands gently rested on his waist. "Glad to know that my husband and my guards both enjoyed their surprise." she gently leaned her head back against Shining Armor’s, while the stallion’s hands slid back up her body and teasingly stroked over her hefty chest.

“More than enjoyed it, honey.” Shining Armor nuzzled at Cadence’s cheek, giving it a soft peck before he smirked playfully; his hands giving the alicorn’s soft breasts a playful squeeze, causing her to moan softly. “Don’t you think your "royal rump" could stand to be a little bigger, though?” he teased, lightly pulling and pushing his hips, sliding his member between the plump pink cheeks some more.

“Oh yes...I agree, dear.” Cadence groaned softly, her blush returning as the stallion gently hotdogged his cock between those two plump cheeks of hers. Glancing forward again, she saw some of the guards getting up and approaching her; most of them still quite aroused. “I think the guards would agree as well!”

TO BE CONCLUDED. As in, now.
