The door to Friendship Castle opened, allowing two alicorns and a small take-out bag access to the mammoth structure before the equally large doors closed behind them. The formerly empty, silent halls of Twilight’s castle now echoed with the sound of mirth, the voice of the castle’s owner once more echoing down the seemingly endless crystal halls.
“I can't believe you really said that!” the smaller, purple alicorn remarked in hushed and slightly guilty tone.
The taller, pink alicorn snorted in a quite unladylike way, raising her head and speaking proudly. “Well, you have to put your hoof down with jerks like him. If you give them an inch they will take a mile, as auntie always said.”
Twilight smirked. “Something tells me Celestia didn't intend on such a saying to be used to justify throwing boiling hot soup into a boorish stallion’s face.”
Cadance snorted again, this time with a little less enthusiasm. “It wasn't boiling, just really, really hot.”
The two giggled and made their way to the living room before flopping down on two couches that faced each other, a small coffee table separating them, while the take out bag was discarded on a nearby end table. Twilight sighed contently, smiling at her sister in law as she settled into the luxurious furniture.
“Thanks again for lunch, I never would have thought to try that new gryphonian place down by the river.” Twilight remarked.
“Ever since we hosted the gryphonian envoy a few months ago I have had a non stop craving for authentic griffon food. So when you mentioned a new place opened up, I couldn't resist taking you there.” Cadance opened the bag and popped a battered mushroom in her mouth. “Besides, I was in the neighborhood anyway.”
Twilight sat a little straighter and eyed her old foalsitter curiously. “Oh? What were you doing in Ponyville?”
Cadance tsked and waved a hoof at Twilight. “If you want that information, you are going to have to do me a big favor first. Namely, eating all these leftovers.” She poked her midsection with a hoof and frowned. “It's hard enough to get rid of the baby weight without all this fried goodness to tempt me.”
The other mare giggled. “Such a herculean task, are you sure I am up for it, Cadance?”
“I think you can do it. The fate of my flab depends on it!” Cadance answered, using a faux authoritarian voice reminiscent of the one Celstia used during celebrations.
Twilight rolled her eyes and levitated the bag of leftovers next to her before popping another delicious morsel into her mouth. “Sho, why were yo in town?”
“Don't speak with your mouth full, Twilight. Am I going to have to threaten to take away Smarty Pants again?” Cadance giggled as Twilight’s cheeks lit up in embarrassment.
The younger alicorn dutifully ate the rest of the leftovers, her embarrassment slowly dissipating amidst waves of delicious fried goodness. Finally when she was done, she rolled up the bag and disintegrated it. “There, will you tell me now?”
Cadance smiled devilishly. “Well, I suppose I did promise you an answer and I don't think you would accept that I just wanted to hang out with my sister, huh?” Twilight blushed and shook her head. “Darn, well, do you remember what day is coming up?”
Twilight tilted her head to the side. “Uh, Tuesday? No wait, Saint Patrick’s Day?”
“You are technically correct on both accounts, but that's not what I was referring to. What happened about a year ago?”
“The changelings ruined your wedding and…” Twilight’s eyes lit up. “Your anniversary with Shiny!” She slapped her forehead with a hoof. “How could I forget?”
Cadance smiled. “Exactly, and I was hoping you could help me with something… personal for Shiny.” Her confidence waned the more she spoke.
“Of course! Do you need to know what kind of Ogres and Oubliettes modules are the newest? Or perhaps what minis are the best?” Twilight was about to continue making suggestions but she found her mouth magicked shut by the alicorn of love.
“No, no, nothing like that. You see, Twilight, when two ponies love eachother very much…” Twilight groaned and rolled her eyes. “They share everything with each other. Why, just last month, after a several intense hours of love making that made my knees weak and left me walking funny the next day we…” By now, Twilight’s face had grown bright red and she blanched at sudden rush of embarrassing information. “Laid down to rest and talk, as well as for me to find a way to keep all of Shiny’s se-”This time Cadance found her mouth magickly shut.
“Get to the point, Cadance!” Twilight hissed, her face now almost completely red.
Cadance just giggled at the other mare’s annoyance. “Anyway, we got to talking and he mentioned how much he missed his little sister. He went on to reminisce about all the special fun he had playing with her, even going so far is to tell me just how deeply he desired to be with her again.”
Twilight’s eyes had been growing steadily larger the entire time Cadance spoke and, by the time the pink princess had finished teasing her, it looked like the smaller alicorn’s eyes were ready to bug completely out of her head. “Would you happen to know about any of these special games, Twilight?”
“Oh, uh, yeah, we used to play our own version of hide and go seek and that's all it was.” Twilight looked left and right, checking if Spike was nearby.
Cadance rolled her eyes and leaned closer to her fellow alicorn. “No need to be shy, Twilight. He filled me in on every delicious little detail.”
Twilight opened her mouth to speak only to slam it shut and shake her head.
Cadance sighed. “He told me you were one of the best cock suckers he’s ever known and mentioned that you may even be better than myself. I would ask you for pointers, but that's not exactly what he had in mind.”
Despite the panic and embarrassment that marred her face, Twilight found herself strangely intrigued, leaning in closer to catch every word. “He casually mentioned how much he had missed it but I knew right then and there that he craved it. He wanted to fuck your mouth and cram his cock down his little sister’s throat, and judging from that look on your face, you're not opposed to the idea.” The alicorn got off her couch and got nose to nose with her sister-in-law. “And frankly, I’d love to watch him do it.”
Twilight gulped. “What exactly do you want from me?”
“Twilight hunny, I want you to let your brother fuck your face and for me to watch. I thought I spelled that out. We can work out the details later. For now, what do you say?” The pink alicorn leaned in close, smiling innocently at her.
The lavender mare turned away from the other alicorn, unable to meet her gaze. “I don't know, Cadance, it's been a long time.”
Cadance shifted to the right, forcing their eyes to meet once more. “If your worried about practice, I have a few dildos you could borrow. Oh, and don't worry, they have not been used.” She smirked. “Much.”
Twilight’s blush returned with a vengeance and she turned the other way, avoiding the smirking face of her old foalsitter. “The last time we were… together, he said he didn't want to do it anymore. Are you sure he wants to... you know?”
Cadance gripped the other mare’s face and brought it close to hers, forcing their eyes to meet once more. “Twilight, he didn't want to because he had to leave for officer school and we started dating after that. Trust me when I say he has always wanted you.”
Twilight’s embarrassment ebbed and a faint smile creeped onto her face. “I’m not saying yes, but if I did, how long would I be gone for?”
Cadance’s smile lit up the room. “No more than a day or two tops, we have a private train that you could use if you have to be back for something important.”
Twilight shuffled nervously, unable to keep a shy smile from spreading across her face. “Well, it would be nice to do you know… that, again. He was always so filling.”
The alicorn of love clapped her hooves together excitedly. “Great! Now, here's the plan.” The two mares leaned in closer, whispering back and forth, discussing the details of their perverted plans.
Outside the room, a certain dragon snapped angrily. “Dang it, that was the juiciest gossip I’ve ever heard! Hey, Peewee, can you get in closer and tell me what they are talking about?”
The phoenix glared down at the dragon with naked annoyance, wondering not for the first time if Rarity was rubbing off on him.
“What? It’s just a question. Sheesh.”
Shining swore quietly, rubbing the spot on his leg that had recently had an unfortunate meeting with one of the many sharp corners that seemed to be everywhere in their crystal home.
“Sorry dear, are you alright?” His wife asked with a hint of guilt.
Just like that the pain seemed to disappear, gently pushed away by the soothing words of the kindest pony Shining knew. He shook his head. “I’m fine, but could you please avoid any more coffee tables? My shin can't take much more.”
Cadance giggled. “Just a little bit further my love, I assure you there are no more coffee tables between here and our final destination.”
Only Cadance could make the words final destination sound sexy. If anyone else had said those words, Shining Armor would have imagined a dungeon or something. But when she said it, he imagined a luxurious bed or a bubbling hot tub. He was tempted to peak through the blindfold to see if he was right, but that would ruin the surprise so he pushed down his curiosity and followed the sound of his wife’s dainty hoof steps.
Ahead of him, Cadance was beside herself with nervous excitement. On the one hoof, he had expressly said he wanted this, on the other, Twilight had said that the last time they had done it it had been… awkward. Regardless, it was too late to back out now and with the door to their bedroom now in view, excitement rapidly replaced nervousness and Cadance couldn't help but giggle.
“You know, for something you said was for me, you seem to be enjoying my present a lot, and before I even opened it, no less.” Shining added with a sly smile.
Cadance blushed. “Let’s just say your present is something we can both enjoy.”
Shining Armor’s smile grew and he couldn't help but think of that time they had invited that really hot maid into their bed for a night. Maybe this time it was two maids! Oh and that new female guard… The male shook his head, scolding himself for even thinking about something like that. Than again, she did giggle a lot like that last time...
The stallion was vaguely aware of a door being opened and being guided inside, the door closing behind him. “We are here!”
Shining hesitated, reaching for the blindfold. “I can take this off, right?”
Cadance rolled her eyes. “Yes you can. And hurry, she's been waiting for you.”
She? The stallion thought. With his interest piqued, he ripped off the blindfold to see their bedroom lit by a multitude of candles, soft wisps of scented smoke slipped across his nose and went unnoticed. Despite the lovingly crafted atmosphere of soft candle light, the smell of his favorite incense and even the sound of distant waves (another of Shining’s favorite), what he saw was more enticing than all that. His jaw dropped and he blinked dumbly at the sight before him.
“Twily?” He asked, dumbfounded by the sight before him.
The alicorn smiled seductively, though Shining could see a hint of nervousness in the otherwise happy smile. She wore a full set of tight black socks that looked to be made of a form fitting but soft material, several straps attached the the socks to the rest of the ensemble, adding an exotic and dangerous vibe. Around her midsection was a lace corset that bound her torso tightly in many straps over a silky, deep-purple fabric that extended beyond the corset itself and draped gently across her flank. The silk was thin and see--through and accented her every curve masterfully. Shining also spied a lacy choker binding her neck and a pair panties that both matched her corset/skirt combo perfectly.
“Wha….” He mumbled, unable to find any words.
Twilight giggled softly and rolled onto her back, her head hanging off the edge of the bed and her mouth open wide, giving the slack-jawed stallion a perfect view down her throat. Shining Armor gulped, he could already feel his cock begin to rise and a heat flare within him, but confusion marred that feeling for the moment and he turned to his wife, who only giggled at his slack-jawed state.
“Isn't that the perfect gift? Your sister’s tight throat to serve as your plaything. I know how much you missed your toy.” Cadance leaned closer, gently picking up her stunned husband’s jaw and putting it back into place. “Oh, and don't worry about holding back. She knows this great little breathing spell so you can go right ahead and fuck her brains out.”
“I… what?” Shining mumbled, his brain still not quite understanding what was going on.
Cadance rolled her eyes and proceeded to climb onto the bed next to the lavender alicorn, running a hoof down the other mare’s body as she did. She quickly settled into a comfortable spot right next to the lingerie-clad alicorn, ensuring she could get a good view of all the action from a more comfortable position.
Noticing that her stallion still hadn't moved, she smirked. “He’s cute, but awfully dumb when he's flustered. Wouldn't you say, Twilight?”
The other mare giggled while still upside down. “You can say that again! And here I was hoping to get my throat fucked good and hard for the first time in years. The stallions and some mares of Ponyville just can't hold a candle to you, big brother.” She smirked, which would have been amusing to the stallion had it happened at any other time.
He gave himself a hard slap and shook his head vigorously, dislodging the cobwebs that clinged to his thoughts. His now fully erect cock slapped against his stomach and he took a confident step forward. He had left a mare waiting and, as a gentlecolt, he would not let this stand. Without another word he walked over to the grinning mare and placed his forehooves on the edge of the bed.
Twilight moaned lewdly. “It’s about time, big brother. I can't wait to feel you inside me.” She extended her magic outward, guiding his cock into her waiting hole only for Shining’s hips to stop with the head of his cock just beyond her lips. “Wait, I almost forgot.” She held his cock tightly in her magic, ensuring he couldn't plunge forward and giving her enough time to work her breathing spell. With that completed and cast, she released the vice-like grip she had on his cock. “Okay, I’m ready.”
“It really has been too long, hasn't it? You forgot the first rule. Do you even remember what you have to do before you get to suck my cock?” He asked disapprovingly, as if talking down to a naughty filly.
Twilight pouted and Cadance giggled, the lavender alicorn rolled her eyes and muttered. “Playthings don't get what they want unless they work for it. I remember, now come closer already, your scent is driving me mad!”
Shining shared an amused look with his wife and shifted his hips forward enough for the young mare to gently kiss the tip of his cock. The soft press of her lips was tender, like the kiss of a reverent lover who was only just holding back her bountiful lust.
The stallion couldn't help but grin like a moron, every motion, every twitch, every noise his sister made reminded him of the past and all the other times they had done this, and he couldn't help but feel nostalgic. Despite Cadance’s best efforts, she simply didn't have the skill or experience Twilight had. Sure, she was good, but Shining had been fucking his sister’s throat for years and years while Cadance and him had only had a real measure of privacy after getting married.
The soft caress of Twilight’s talented tongue along his shaft drew his attention downwards and Shining couldn't help but grin proudly. She remembered everything he loved, his favorites were the long, gentle, reverent licks applied to all sides of his cock, which got him fired up while giving him a taste of the pleasure that her tight throat promised.
Up and down her brother’s hard shaft Twilight licked, pausing at the tip to plant another quick kiss. A few more repetitions of this and Shining Armor had become painfully hard, his entire body screaming at him to stuff himself down her throat and fill her with cum. That desire would have to wait though, and the stallion let out a low moan and ran a hoof down Twilight’s neck teasing the mare with his gentle touch.
“Alright, I hope you’re ready, because I sure am.” Shining Armor whispered into the mare’s ear.
Twilight’s face instantly lit up and she pulled back until her mouth lay just beyond the end of Shining’s cock, her magic guiding him into her waiting hole.
Shining laughed at his sister’s enthusiasm and he mused idly about whether or not he had given her her oral fixation. Shaking the the thought away, the stallion gripped the bed and pushed forward slowly, testing the waters and hoping she had not lost her edge.
His head easily slid past Twilight’s lips and into her waiting mouth and, within seconds, she could feel his cock begin to hit the back of her throat. Feeling something was off, Twilight shifted slightly, allowing her brother a clear line to the back of her throat and deeper still, an opportunity he did not hesitate to take and he quickly thrust forward, pushing his cock deeper.
Cadance couldn't help but gasp at the sight of her husband’s cock begin to bulge her sister-in-law’s throat. She gently ran a hoof down her own neck at the sight, imagining the many times he had done that to her. Sure, she had felt it plenty of times, but she had never witnessed it before and the sight was as fascinating as it was oddly arousing.
Noticing that his sister hadn't asked to slow, gagged, or tapped his leg, Shining took that as his sign to continue and he slowly walked his cock deeper, spreading his sister’s throat around his not-inconsiderable size.
The stallion couldn't help but moan aloud, the tightness was perfect, the way his sister’s tongue rubbed his cock before it pushed down her throat was somehow even better. The memories of doing this hundreds of times before was a nice addition and to top it all off, he could see that his wife was getting into it as well. The way she pressed her mound against the bed, seeking relief, was the icing on the cake as it meant she was enjoying this as well and this wasn't solely about him.
With the mild guilt of feeling selfish out of his mind, Shining pushed deeper with more energy, his medial ring passing between his sister’s lips and pressing into her throat and deeper still. Cadance couldn't help but lean closer when she saw the noticeable bulge he made in Twilight’s throat and she found herself leaning closer and running her tongue along it. The taste of Twilight’s fur was present, but within Cadance’s mind, all she could taste was the familiar flavor of her husband’s cock.
The mare carressed and worshipped the bulge her husband’s cock made, running her tongue along it, hoping he felt her touch. Though the stallion seemed distant, his mind clearly more occupied by the all-consuming desire to fuck his sister’s throat, said sister was almost as focused on Cadance as she was her on own brother. The pink princess could feel the love and affection radiating from the mare and quickly redoubled her efforts. She pressed her soft cheek against her neck, nuzzling Twilight’s bulging throat and pressing herself against the smaller mare. She felt a soft murmur of appreciation rise from the darker alicorn and she responded in kind, pressing her lips against the bulge over and over.
Twilight wasn't quite sure what was going on, but by now she didn't care. Cadance’s kisses and nuzzles made her fill with warmth, all the while her brother’s balls were getting closer by the second and she couldn't help but feel giddy at the thought of those big round balls getting smooshed against her face. She missed the taste, the feel, the scent, and with their return she was in heaven.
She inhaled deeply through her nose, though she no longer needed to breathe, she still could and she used this opportunity to delight in another chance to fill her nose with her brother’s potent scent. She could feel his pheromone-laced musk begin to work its magic nearly instantly, her pussy tightening at the smell, its already damp interior becoming more and more wet as the mare’s lust-addled mind told her to body to prepare for what it thought would happen next.
Shining Armor grunted and let out a low moan. “I hate to say it, but her throat might even be better than yours, dear.”
Cadance shrugged. She would get him back eventually, but for now she would rather be enjoying herself.
Slowly, the stallion eased the last few inches of his length into his sister’s mouth and down her throat. His balls rested perfectly against the mare’s face, reminding her of her place and filling her nostrils with his scent. Shining let out a sigh of contentment, though that was stifled somewhat when he felt the familiar rise of his orgasm.
It's too soon, I want to enjoy this! He thought desperately. Using every trick he knew of from biting his lip to thinking unsexy thoughts, he bought himself a little longer, but he knew he wouldn't last long.
Noticing the stallion’s expression, Cadance giggled. She knew he had come close and she couldn't help but want to tease him, but this wasn't the time or the place. The mare lit her horn and cast a quick spell, one she knew by heart and was particularly good at casting on her husband.
Shining grunted and shifted awkwardly, stopping himself mid-thrust as he felt the spell course through him. Twilight felt the telltale energy of a spell being cast, but couldn't tell what it was.
“I have a surprise in store for the both of you.” The spell reached out and gripped the stallion’s balls, forcing them to grow. “With this spell, my stallion can outperform an entire guard’s barracks.”
Shining Armor’s short thrusts became more and more erratic and he grunted when he felt his balls grow larger than ever before. Twilight was enjoying herself perhaps even more than her brother, there was something about her face being smacked by the enormous, full balls of her older brother that made her squirm in delight, all the while she felt the same enormous orbs gurgle as they were forced to become larger. She could hear the sloshing of his impressive load within his balls, teasing her with the largest and most impressive orgasm she had ever imagined.
Unable to stop himself, Shining thrust as deep as possible, his cock already shooting the first load of hot cum directly down his sister’s throat. The mare gulped, though the act was unnecessary as the stallion was so deep his load didn't have far to travel before landing in the mare’s stomach and beginning to fill it.
Twilight could do little but wait. Though she didn't cease the gentle squeezing of her talented throat muscles, she was also quite distracted by the fact that her vision was completely obscured by the largest pair of testicles she had ever seen. Her already overloaded mind was flushed with a new wave of pheromones, a new wave of lust and yet another orgasm, the sensation of having her face pressed against his sack driving her to a new height of pleasure.
Load after relentless load shot down the mare’s throat and into her stomach until she could feel it shift and bloat, a noticeable bulge growing on her stomach. Cadance hummed approvingly, running a hoof across the taut flesh of Twilight’s growing belly. Despite her desire to see it grow larger, she forced herself to shut the flow of magic and stop the endless tide of cum that threatened to fill Twilight to the brink. Alicorns were stretchy after all, but they still needed time to adapt, time that they had in abundance.
Twilight’s corset and the rest of her clothing, minus her socks, had now been stretched well beyond its limits and, despite becoming three sizes larger than what they were originally intended for, still did not tear. Twilight looked down at her large belly and stretched clothing and sighed; that outfit had been one of her favorites. She would have to buy another one from Rarity the moment she returned home and compliment her on just how strong her sewing was. The lingerie was gone with a flash of her horn and teleported into her overnight bag, much to both Cadance and Shining’s dismay.
The male grunted feebly, feeling the magically enhanced growth slow and finally stop, his cock spurting a few last weak loads down his sister’s throat before stopping completely. He moved back, trying to pull out of her mouth, but the sudden spell and the powerful orgasm had left him woozy, and one step instead became three and he tumbled out of her mouth and landed on the cold floor with a thump.
“Ow! Warn me before you do that, babe.” Shining requested with a groan, rubbing his aching head.
Cadance scowled briefly. “Oh, fine, but you must admit that was incredibly sexy.”
By then, Twilight had finished gulping down the last of her brother’s sperm and licked her lips triumphantly. “That was… so hot.”
The couple giggled, they remembered their first time trying that spell and they both had similar reactions. Cadance got up suddenly, drawing the gaze of her fellow alicorn who moved to get up as well. A firm pink hoof against Twilight’s chest made her stop and look up/down at her sister-in-law.
“What? Did you think I would be okay with just watching after that spectacular performance? I want to use that throat of yours myself.” Cadance smirked, drawing a confused look from Twilight who noticed the mare’s horn had begun to glow.
It was a glow that suffused her crotch until it glowed just as brightly as the mare’s horn. Twilight’s analytical mind was turning at mach one, but before she could come up with anything, the spell activated. A small pink and white mottled cock began to grow from the mare’s waist, accompanied by an equally small set of balls. They didn't stop growing there though, and they rapidly extended until it rivalled and then finally surpassed her brother’s cock in size and length. With a heavy slosh, her balls dropped to their full massive size and the glow vanished.
“Wow.” Twilight gaped, in awe of the massive new addition to her sister. “We are so exchanging spells after this.”
“As long as you teach me that breathing spell, then we got a deal. Now get ready, I’m far more impatient than your brother.”
Twilight dutifully nodded and got back into position and was about to open her mouth when she felt her jaws pulled open and the head of Cadance’s new cock pushed inside.
The subservient cock slut expected to feel her throat violated quickly, she was however not ready for just how quickly that would happen. The instant Cadance’s cock was inside her mouth, Twilight felt the other mare’s muscles tense before suddenly pushing forward, plowing into the back of her throat and further still. Not for the first time Twilight was very happy she did not have a gag reflex nor did she need to breathe as she was pretty sure she would have gagged, and subsequently began to freak out at the sensation of having her throat stuffed full of mare cock. Her choker stretched, barely able to contain the amount of horsecock forcing it to change shape.
She didn't stop there though and, after a second to take a step closer, Cadance was already thrusting deeper. Her medial ring slipped inside and down her throat, making Twilight’s neck bulge even further as it was forced to take Cadance’s considerable size without so much as a break. As the medial ring pushed deeper, it briefly pressed against Twilight’s already-stretched choker, forcing it to continue to stretch even more. The thin leather and weak metal that made up the necklace had reached its limit and it snapped under the brutal assault of Cadance’s massive cock.
Shining had righted himself and made his way over to the bed by then and stood in awe as his wife brutally fucked his sister’s throat without mercy. His cock twitched and he couldn't help but touch himself as he saw more and more of her mottled cock disappear down Twilight’s throat.
The size didn't bother her, the length didn't bother her, but the sheer insistence of Cadance’s thrusts were enough to throw off even a seasoned cock slut like Twilight. She could do little but try not to panic while holding herself in the position and allowing her sister to have her way with her body.
It didn't take long for Cadance to bottom out, her large balls smacking audibly into Twilight’s face as she settled in to a better position, her cock firmly down the younger mare’s throat and her head perfectly in position between Twilight’s legs.
With the mare finally as deep in her throat as she was going to get, Twilight was finally able to push aside the panic she had been fighting and focus on pleasuring the newest cock to ram down her throat. She quickly squeezed down on it, lavishing it in loving affection with the use of her tongue and planting a nice, firm kiss against the base of Cadance’s cock as a thanks for the gift.
The other mare sighed softly, enjoying the feeling of having something wrapped around her cock. She giggled when she felt Twilight kiss her crotch and she couldn't help but think to herself. “You know, dear, I think your sister’s throat is even better than yours. You should get some lessons from her.”
Twilight was only vaguely aware of what her sister had said, but Shining Armor heard her loud and clear and blushed madly at his wife’s words. He couldn't help but consider it as well; his wife deserved the best and if Twilight could give him some pointers… He shook the thought from his head. Later. He concluded.
Meanwhile, Cadance was learning all the many ways Twilight had brought her brother to orgasm using her only her mouth and throat, leaving the other alicorn feeling almost guilty. She looked to the side, pressing a hoof against Twilight’s cum-belly and frowning slightly, a seed of envy rising within her.
She should have a nice full belly and something to suck on. She ignored the purple princess’s moan and eyed up her eager husband with hunger in her eyes. “I am getting rather envious of you, Twilight. A nice, hard cock down your throat and a hot load resting in your belly.”
Shining’s ears picked up and he put a hoof on the bed in a move to fill that particular need, but stopped when he saw his wife’s horn light up and a devilish smile spread across her face. He knew what his wife had in mind and he knew he was in for a show. Instead of getting on the bed, he sat at the edge of it and began stroking his length while he watched his wife work her literal magic.
Twilight’s eyes went wide. Despite the fact that the only thing she could see were Cadance’s massive testicles, she could feel something strange worming its way into her flesh and she instantly realized it was a powerful transmutation spell that sought to change her physical body. She couldn't help but smile when she felt the spell centeralize itself on her crotch and she let any thoughts of resistance to flee from her mind. She was going to enjoy having a cock of her own and maybe even get a little payback on the pink mare for her rough treatment. Though she had to admit that something about being treated like nothing more than a hole felt strangely good.
Despite her acceptance of the spell, it still was quite the strange experience to feel a new organ grow from your crotch. So strange that she nearly forget about the cock still buried down her throat, a fact that her sister reminded her of with a small but forceful thrust that reminded Twilight of what she was doing. Twilight gulped and got back to work, dutifully sucking the other mare’s cock and becoming only vaguely aware of her cock growing with a pair of balls coming to rest behind it.
The lone stallion couldn't help but smile when he noticed that his wife had made his sister’s cock nearly identical to his. It was the same size, shape and diameter, and even had that cute, mottled star shape near the base. Though, now that he thought of it, he wasn't sure if that was genetics or magic. Regardless, it was hot as hell, almost as hot as watching his sister nearly choke on his wife’s fat cock.
Twilight’s new cock had grown to the perfect size and her balls rested neatly between her legs, with enough sperm in each to impregnate a small village. Cadance inhaled a quick lungful of its scent before opening wide and swallowing nearly all of it in one quick go. The mare whose cock she was desperately swallowing squirmed and squeaked at the sudden sensation, but even then she didn't forget her duty to the cock lodged in her throat.
Down the pink mare went, within seconds she had pushed her head all the way down Twilight’s newly-formed cock and planted a loving kiss on the other mare’s pelvis. She was determined to show that, despite not being the best cock sucker in the room, she made up for her lack of finesse with sheer determination. The purple cock fit inside her like it was made for her and Cadance couldn't help but grin around the huge invader in her mouth, for it brought on memories of her husband and his own impressive appendage.
She pressed her tongue against the underside of Twilight’s cock, feeling every vein and bulge with loving attention. She wanted to stay down there longer, and perhaps try to outdo even Twilight’s considerable skill, but she did not have the other mare’s spell and thus she was forced to pull back, seeking a fresh lungful of air.
Shining Armor’s hoof had stopped midway down his cock and he had stared in rapt attention as he watched his wife impale herself on his sister’s cock. The way her neck bulged as it traveled deeper, bottoming out in seconds, was enchanting and he couldn't look away until he saw the pained look in her eye and her head pull back in defeat as she ran out of air. He was vaguely aware that watching his wife get fucked should make him feel something other than aroused, but in that moment he couldn't think of it - all he wanted to see was his wife’s head connecting with his sister’s crotch as she slammed back down again and again.
As if reading his mind, Cadance did just that, trying to beat, or at least match, Twilight’s talented throat muscles with a fast and furious pounding of her throat. The purple alicorn was not to be outdone and she worked every muscle she knew how to while her hooves wrapped around the back of the pink alicorn and held her close, forcing her to go as deep down Twilight’s throat as possible. On and on the two went back and forth until Cadance was forced to admit defeat. She could feel her own orgasm coming far faster than what she assumed Twilight’s was and she tapped the mare’s leg, signalling for her to slow down for a moment.
Confused but compliant, the other mare stopped milking the cock still lodged unmoving in her throat, though she couldn't help but continue to lavish the other mare’s crotch in kisses while her tongue worked its magic.
Cadance pulled her head from Twilight’s crotch and, with an audible pop, she released her sister’s cock from her mouth, a small trail of spit connecting them still until it fell limply on Twilight’s torso. The pink alicorn quickly regained her breath and looked over to her husband, who was still masturbating furiously to her right.
“Shining, dear, don't you want to join in on the fun? There is a hole right here that needs filling, after all.” Cadance lifted the enormous purple sack from the bed to reveal Twilight’s glistening slit and tight virgin ass beneath it. “I’m going to need help turning this naughty sister of yours into a bloated cum balloon.” Cadance gave the mare’s wet cunt a slap, drawing a murmured moan from the other princess.
The stallion moved closer, eager to follow his wife’s suggestion, until the rest of his brain caught up with his actions and he stopped and shook his head. “Twilight and I had only ever done oral before, so that's still not a line I’m willing to cross. Also, shouldn't you first ask Twilight before offering her hole up like that?”
Cadance winced. “I’m sorry, baby, I just assumed.” She leaned forward and planted a kiss on Twilight’s cock. “I’m sorry to you too, cutie. If you feel that strongly about that hole, why don't you fuck the other one? I know how much you love anal.”
The stallion hesitated and looked down towards Twilight’s face, which wasn't visible through Cadance’s balls. “What do you think Twilight? Would you be okay with that?”
Twilight seemed to think it over, only to nod her head slightly. Cadance smiled and pulled Twilight’s legs up, displaying her tight virgin anus more prominently. “Then it’s settled. Now, put it in her! I want to feel her squirm when you fuck her ass.”
Shining grinned and shuffled closer, guiding his cock towards his little sister’s awaiting hole. Once in position, he wasted no time in plunging his hips forward and ramming himself against her unyielding anus. Both stallion and mare alike couldn't help but feel a shock of anticipation at the brief touch, both annoyed but eager at the fact that he had yet to bury himself within her.
Winding up again, Shining thrust forward with all the force he could muster and was relieved to feel the head of his cock push inside his sister’s ass and sink a few inches inside. He didn't rest on his laurels though, and he took a page from his wife’s play book and ruthlessly thrust again and again until he finally had bottomed out inside her.
Twilight was no stranger to having things put into that particular hole, but she had never tried to ram something quite as big as Shining inside her and, the moment she felt their hips connect, she let out a strangled gasp of surprise. Shining was also quite amazed that he had slipped inside so easily, even with his sister’s spit clinging to every inch of his cock.
Noticing that her job was done, Cadance leaned down and once more took Twilight’s length into her mouth. She abandoned the slow, tiny thrusts she had been maintaining and instead chose to focus every last bit of her ability on pleasuring the lavender alicorn, content to merely use her as an oversized cock sock while she gave back. Her lips pressed against purple fur once more and she could feel the cock’s owner groan in pleasure, her throat milking Cadance’s cock.
Shining Armor recovered quickly from the shock of slipping inside his sister so fast and got to work. The positions were awkward with his wife bobbing on his sister's cock while he was bottomed out inside said sister, but with a little maneuvering it was doable and, within a minute of filling his sister’s ass with his cock, he began to move in earnest. No more sloppy thrusts or awkward attempts, this was what they both wanted but had never had the guts to even propose doing.
The taboo of fucking his sister was forgotten the moment he began to move, and Shining Armor was only dimly aware of the line they had crossed by the time he began fucking his sister’s ass with real, powerful thrusts. He didn't think of what others might think of him as his cock seemed to melt into his sister’s ass and he didn't spare even a moment of thought to the fact that he desperately needed to fuck her hard and long, finally stopping only after she had cum down his wife’s throat and he had deposited his own considerable load inside her ass.
The three ponies wasted no time with romance or pleasantries, each one doing everything they could to bring one or both of the others to orgasm as quickly as possible. There was a certain manic intensity that so gripped them and they all seemed to instinctively know just how much the others needed to finish. Cadance wanted nothing more than to fill Twilight to the point of bursting. Twilight was beginning to tire, her throat cramping up and, as much as she was enjoying herself, she had to admit that she needed a break. Shining Armor was a kid once more, having just crossed a taboo with his sister and he couldn't help but feel young again, and with that feeling came a youthful enthusiasm not tempered by his experience.
It wasn't long before all three of them could feel their orgasms beginning to arrive, though they hadn't expected them all to start coming at the same time. Cadance could feel it coming and sped up her attempts to suck Twilight off. Shining Armor bit his lip slightly, while Twilight twitched and moaned, her muscles getting tense. The pink alicorn smirked around the cock in her mouth and, without warning her lovers, lit her horn and began to cast a now-familiar spell over all three of them.
The other two’s eyes went wide when they felt their already-impressive balls begin to swell even more. Twilight was the first to cum, overloaded from the unfamiliar sensation and the fact that two of her holes were plugged full of cock. She came hard and fast, her cock spraying like a firehose, the first massive spurt signalling that the alicorn was a little more pent up than she had let on. Such an impressive amount of cum ould have dissuaded a lesser mare, but Cadance was no such pony and so she simply pushed deeper, ensuring that the other mare’s cum simply shot straight down her throat and into her rapidly filling belly, which gave her the perfect view of the purple princesses’ prominent ballsack as it gurgled and grew. It pushed past its already impressive size and into the realm of the absurdly large. It grew to a considerable size before the pink princess finally stopped the flow of magic; she didn't want to push it too far with her new lover, but she had no such reservations with Shining and herself.
Their balls continued to grow, easily becoming far larger than any normal pony’s should be capable of. Virile sperm flowed into and out of their ever-growing balls, filling them faster than they could empty and leaving them feeling perpetually relieved and pressured at the same time.
Shining came next, and though he wasn't as impressive as his sister, he also did not seem satisfied and continued to rut her while he was cumming, trying to milk every last drop out of himself and his sister. Cadance came last, having held on until the last moment as she wanted to witness every cute moan and subtle twitch that the lavender mare went through, and it was worth it.
Meanwhile, their balls had finally stopped growing, having continued to pulse and distend all throughout their orgasms. The sensation of growth accompanied with being painfully full were not new to the couple and they had long since gotten used to that part of their anatomy growing to inequine sizes. Cadance allowed her magic to slowly fizzle out, disrupting the last vestiges of the spell and leaving their balls at their impressive size... for now.
She had already ensured she was as deep as possible inside her sister before she came; she didn't want even a single drop to be wasted. After all, how would she inflate her darling sister if she didn't give her every single last drop?
All three were in their own personal heaven, but even then, all things must come to an end, and with Cadance’s and Twilight’s stomach’s growing with every spurt of cum, they were forced further and further apart.
It wasn't long before the two alicorns were pushed apart by the sheer size of their bellies, the prodigious amount of cum being pushed into each other also pushing them apart. Cadance was slipping further and further back on Twilight’s cock, unable to keep it as deep as she'd have liked with an enormous cum belly in the way. Even then she hung on for as long as possible, slipping further and further back, swallowing every drop she could while knowing even that wouldn't last long.
Sure enough, it was only a few seconds longer before she felt her neck reach the end of its reach and one last spurt of cum was all it took to push the lavender cock out of her grasp. Cadance frowned but couldn't help but giggle when Twilight’s still-orgasming cock began to spray her husband with its potent load. The stallion was caught off-guard and still in a trance-like state of watching his sister’s belly grow to an enormous size. A glob of alicorn spunk hit him in the face and only his quick reflexes saved himself from getting it in his eye.
With a hoof now protecting his face, Shining Armor heard his wife’s giggles and saw her grinning face. Now with a target in mind, Shining gripped his sister’s cock and aimed it at the distracted pink alicorn, who promptly caught two sizable loads directly in her face.
This time it was his turn to giggle at somepony’s misfortune, which inevitably drew Cadance’s ire. As they wrestled back and forth with Twilight’s cock, both trying to spray the other, the alicorn beneath them continued to stretch and grow, their waning orgasms distending her belly further than one would think possible.
Then, just as Shining had wrestled Twilight’s cock from his wife, it spurted one last time and went limp, along with the rest of Twilight’s body. The couple exchanged a look of panic, their own orgasms having died down not long before Twilight’s had. Quickly the pair extracted themselves from the bloated, cum-filled mare. Cadance’s cock came out clean after having dumped every last drop directly into the mare’s stomach, while Shining’s released a small torrent of cum that flowed from Twilight’s abused hole.
“Is she okay?” Shing asked nervously.
Cadance quickly leaned down and cast a quick dispel, getting rid of Twilight’s breath spell. Her face instantly softened and she placed a hoof over her beating heart. “She's fine, just passed out, but the spell was still working.”
Shining couldn't help but grin at that. “I guess she isn't used to just how much pleasure two ponies can dish out.”
Cadance cast a quick scanning spell over the inert pony and let out a sigh of relief. “I guess so. She's completely fine, though. We must have overloaded the poor dear.”
The stallion sighed and gently carressed her sister’s cheek. “Help me make her a little more comfortable. Something tells me sleeping with your head over the side of the bed is a good way to get hurt your neck.”
Cadance nodded and lit her horn, wrapping her telekinetic aura around her sister while Shining did the same. Together they gently deposited the bloated mare on their enormous bed, both watching her cum-filled belly shake and slosh with each tiny movement. Now in a better position, Cadance quickly grabbed a plug from a nearby dresser and gently used it to block Twilight’s gaping ass, ensuring no more of her husband’s cum would be wasted on their sheets.
When Cadance looked over to her husband, she couldn't help but giggle. The stallion was staring wide-eyed at his sister, unable to look away from just how massive the mare had become. Her bloated cum-belly was easily as large as she was and, for a moment, he wondered if perhaps they had gone a little too far, but he dismissed the thought. Cadance and him had experimented with getting to that size before and with, a little magical assistance, their recovery was quick, painless, and rather enjoyable.
“Like the view, my love?” Cadance purred as she slithered close to her husband.
Shining blinked and tore his eyes away from his sister. “I uh, yeah. I just can't get over the fact that she let us do that, and just how much she enjoyed herself. How many orgasms do you think she had? I was vaguely aware of one or two near the end, but I must admit I was, well...” The stallion scratched the back of his neck. “... a little distracted.
Cadance giggled. “Shining Armor not paying attention to his lover, how scandalous.”
“It's not like that! I-” a pink hoof pressed to his lips shushed the stallion.
“I'm just teasing you. What's gotten you so wound up? You usually love a little teasing.”
Shining sighed and gently ran his hoof over the bloated purple cum balloon his sister had become. “This is all just so overwhelming. I keep pinching myself to see if this isn't some anniversary gift from Luna in the form of an amazing dream.”
Cadance giggled. “Well, I did ask her about something like that, but I assure you, this is real life.”
The stallion retracted his hoof and flopped down on the bed. “Well, that explains why I feel so exhausted. I don't remember a time a dream made me feel that. Thanks for the amazing anniversary gift, Cadey, I'm afraid my present is going to seem a little lacking in comparison.”
Cadance frowned and pulled her husband’s face away from the sight of Twilight’s bloated belly and towards her disappointed eyes. “Are you giving up already? I had so much more planned. And look.” The mare presented her belly, which was a far cry from the enormous size of Twilight’s. “It's so small, and empty. You wouldn't want your wife to end the night without being filled with cum, would you?”
Shining Armor blanched. Between the puppy eyes, the guilt and the gorgeous body of his wife being laid out before him, there was no way he could resist. “Well…” He muttered, feeling his exhaustion slowly slipping away, replaced by a slowly building desire to see his wife filled with cum.
Cadance snorted and stood up on the bed, looking down angrily at the limp stallion. “Shining Armor, you are going to fuck me until I’m at least as big as your sister. Is that understood, soldier?”
The stallion grinned and shook his head. His wife knew all his buttons and wouldn't hesitate to press as many as she needed to to get what she wanted and the sharp, commanding tone of hers was the last straw.
The mare stomped her hoof on the plush, comfortable bed and scowled in mock annoyance. “So, what do you have to sayyy-”
The mare was suddenly lifted from her hooves by a powerful, blue telekinetic field and deposited on the stallion’s lap. Her own semi-erect cock pressing against his limp but quickly hardening one.
“I say that sounds like an order I am just going to have to obey.” He leaned forward and kissed his wife.
She melted into his embrace, squishing their cocks together beneath her slightly bulging cum-belly. Like old lovers, they quickly interlocked their hooves around each other, knowing exactly how the other liked to be held. Their tongues intermingled, neither wrestling for dominance nor submitting. They knew where they stood and they both enjoyed the familiar taste of the other. There was something calming about it, familiar but also endlessly enticing. The couple, despite being a year into their marriage, still felt as though they were on their honeymoon.
Every time they made love it was with the same manic intensity of their wedding night, as if the other pony was going to vanish into the aether if they slowed down for even a second. Sure, they had their occasional quiet moment, but at the end of the day, neither of them could resist each other for long and they inevitably resorted to the same frantic intercourse of teenagers trying to hide from their parents. Shining Armor wondered idly if that was the reason he always felt so young when they kissed, or perhaps it was simply the powerful memory of the first time they had kissed when they were both teenagers. Either way, it didn't matter now, he had a job to do and a wife to fill.
By now they were both incredibly hard and throbbing with need. Shining Armor acted first and with the same youthful determination that he usually had. Grabbing his wife in his aura once more, the stallion levitated her up and off of his chest. He quickly aligned his now-hard cock with Cadance’s dripping cunt and brought her down hard and fast on the lengthy organ.
Cadance let out a surprised eep that devolved into a content moan of pleasure. She had felt his powerful cock plunge deep into her pussy, filling her utterly in a single moment. He did not stop there though. Despite the wash of pleasure that arose from feeling his wife speared along his length, he wanted more, and he knew she did too.
His horn’s light grew in intensity, illuminating the room better than the few candles still left. The mare could feel her body being gripped tighter, his expert skill and precision meaning he was able to hold her close and tightly without making it difficult to breathe or restricting her movement too much. It was just the right balance between control and lack thereof that they both enjoyed immensely.
With Shining Armor’s horn glowing brightly, she felt her body lifted off his cock, only to be pushed back down, his hunger too intense to merely allow gravity to do its work. The powerful sensation of being used made the mare moan and she relished the feeling almost as much as she enjoyed the feeling of being filled once more.
Up and down she was pushed and pulled, her body used like a mere sex toy. To his credit, Shining Armor didn't even break at the act, more than capable to keep up their manic pace for longer than what they would probably find necessary. Though this wasn't the first time they had done this, there was still an air of freshness to the act as it wasn't something they could try all the time.
Within a minute the pace they had reached turned the steady slap of their bodies connecting into a nearly continuous cacophony of pleasure. Shining Armor’s stifled moans contrasted Cadance’s unbridled screams of pleasure, testing the upper limits of the privacy spell placed upon the room.
Shining rolled his eyes when a particularly loud moan pierced his ear drums. Thinking quickly, the stallion gripped the mare’s cock mid-bounce and brought it up to her lips, bending her head slightly so the tip slipped inside easily.
Her surprise didn't last long and she eagerly began to suck away at her own massive length, her eyes meeting her stallion’s every once in a while in order to shoot him a seductive look. He loved watching his wife suck her own cock, especially while he was already balls-deep inside her. Something about her entire body being used for the sole purpose of pleasure stirred something in the stallion and he couldn't help but imagine how hot it would be to feel another cock rammed inside her tight ass while he was inside her cunt. Maybe when Twilight woke up, he could convince her. Again he pushed the errant thought from his mind; that was for later and his job remained unfulfilled.
Cadance couldn't help but grin around the the cock in her mouth. She had noticed the stallion’s expression go from distant look, a clear indication he was thinking, to a sharp and wicked smile. Whatever he had thought of was probably going to be hotter than tartarus in summer.
She pushed her head further down, trying to work her neck into a position where she could take her own cock deeper into her mouth. After a few more trips down her husband’s cock she had managed to wedge a few inches of her cock into her mouth and instead of bobbing her head up and down like she usually would, she merely let her husband bouncing her to do all the work, leaving her to merely enjoy somepony else doing all the work while she idly ran her tongue along the flared head of her cock.
Sure, it didn't taste as good as Shining’s or even Twilight’s, but her cock was both familiar and, she had to admit, it wasn't half bad. It felt a lot like a meal you would have often. It was neither amazing nor different, but it was still good enough to bring you back often. She was vaguely aware that the average pony might find sucking your own cock to be distasteful, but Cadance couldn't disagree more. She had spent the entire afternoon, evening and night sucking herself off after giving herself a cock long enough to taste. Though she wouldn't admit it out loud, especially to her husband, she secretly craved the delicious taste of her own sperm and there was something about filling herself over and over that drove the mare mad with pleasure.
A particularly powerful landing jammed Shining’s cock against the entrance to Cadance’s womb, drawing her from her blissfull sucking and forcing her to pay more attention to the cock not inside her mouth. It was then that she realized how close her husband was to orgasm, his jaw was tight, his teeth bared and a look of determination was spread across his face.
Her own orgasm had been close for a while but she had held off, hoping to cum at the same time her hubby did and, from the look of things, that wasn't far away. She quickly lit her horn, knowing fully well that their favorite spell would push them both over the edge. She breezed through the spell, having long since learned how to almost perfectly cast it based on instinct alone.
With the spell now complete and the power now flowing to her horn, she took a moment to wedge her own cock as deep as possible into her mouth, knowing fully well how difficult it would be to contain once it started unleashing a torrent of cum into her gullet. Shining Armor saw the telltale glow of spellcasting and picked up the pace, making sure to enjoy the last few seconds as much as possible before the inevitable arrived.
And arrive it did, with a flash of pink light the spell quickly wrapped around their balls and seeped into their flesh, suffusing it with arcane power and beginning to temporarily alter their bodies. Cadance was a brilliant spell caster when it came to spells that fell within the realm of love, but one thing she was less brilliant at was the subtle art of controlling one’s power.
She could feel her considerably large balls begin to grow and change, filling with potent seed. With just how virile she was as the alicorn of love, as it stood right now she probably could have impregnated an entire village of mares and had some left over. Despite her experience with the spell she, was not an expert with dividing her attention and she instead focused the majority of her magic on her husband, desiring more to feel his cum fill her womb than her own cum to fill her belly.
As such, when the spell began to alter a particular part of their bodies, it did so faster than normal, with the changes being far more pronounced than the spell was originally designed to do. The stallion felt his already stretched and warped flesh change and shift, growing larger and making room for even more cum than his already mammoth sack contained. As his balls continued to grow, he could feel his already swollen balls begin to fill with more potent seed, almost instantly becoming painfully full. He was in luck, however, and the second he felt his balls distend and fill with an amount of seed that would put a fully grown dragon to shame, he also felt his orgasm arrive, instantly relieving some of the pressure.
The first blast of cum that hit Cadance’s womb sent her over the edge, her cock twitching madly as it began to spurt a thick, potent load straight down her throat. As always, Shining Armor’s load was impressive, but even more impressive was his pressure. She could already feel her womb begin to fill as her husband’s now-flared cock pressed against it and filled her more and more with each passing second. As he came he felt his balls continue to grow, his wife’s lingering spell continuing to force his body to change and make room for an ever larger amount of cum.
Even with her attention diverted more to her husband’s balls, hers had still grown considerably and though they were not as big as his, they were bigger than Twilight’s and were more than capable of filling her stomach. Her belly was so full by then that she doubted she would have to eat for several days and with how potent and nutrient rich alicorn essence was, she would feel full and satisfied until the last of her own cum had finally been digested. Though the feeling of having her womb blasted with sperm was a good one, it couldn't hold a candle to just how magical it felt to no longer need to eat, while walking around with a heavy, cum filled belly, all the while feeling absolutely stuffed.
With her husband’s attention wavering, Cadance was able to move her forehooves, allowing her to place one hoof on her belly in order to feel it grow and fill, while the other helped to hold her cock in her mouth, ensuring that not a single drop of her delicious cum would be wasted. That was until the inevitable would happen and her own growing belly would make reaching her cock impossible, but she would cross that bridge when she got to it. As an afterthought, she released the hold her magic had on her husband’s balls, letting the swollen, watermelon-sized organs to finally stop growing.
Her husband’s usually impressive load was put to utter shame as he relentlessly filled his lover with a seemingly unending amount of jizz. Cadance could feel her belly grow by the second and soon she could hear it slosh as Shining’s aura faltered. The mare pressed downwards, grinding herself against the stallion’s cock and ensuring every last millimeter of cock was pressed inside her, which had the added benefit of ensuring all the cum Shining had to offer ended up inside the mare of his dreams, where it belonged.
Slowly, Cadance could feel her belly grow until it pressed against her cock, pushing it further and further away. Her hoof did its best, pressing her cock against her squishy belly and keeping it from escaping her for now. That didn't last long though, even with the combined effort of her hoof, her magic and her frantic wishing, her cock slipped out of her throat and drew painfully close to her lips.
The mare frantically gulped down load after load until finally her distended belly was simply too much. With great remorse, the mare felt her cock slip from her lips and begin to spray wildly, going so far as to hit even the ceiling.
By now, Shining Armor’s magic had waned to the point of breaking and he could feel his last reserves begin to dwindle. Using what little magic he had left, he slowly lowered his wife into a more natural position. Now with all four legs on the bed with his cock still inside her, Cadance quickly gripped her cock in her magic and brought it close to her husband’s lips.
The stallion’s face and head were nearly covered in cum by now and he hardly even bat an eye when he felt himself being pressed down and forced to take the last few loads directly from his wife’s still spurting cock.
He dutifully chugged every last drop she had to spare, swallowing quickly lest he become overwhelmed by the sheer amount of his wife’s sperm. He felt his own orgasm begin to dwindle, the amount of cum in his once bloated sack dwindling to its last litre or so. As if on cue, he felt his wife’s cock stop twitching and begin to grow still.
Now able to savor the taste somewhat, Shining caught his wife’s load in his mouth and swirled it around with his tongue until he felt his mouth fill almost completely, then he swallowed quickly and awaited the next load. Unfortunately, that was the last she had to offer though and the stallion felt strangely empty and a little envious of his wife and sister. That thought didn't last long, though. Something told him his wife still wasn't done yet.
Cadance smiled triumphantly, running a hoof across her bloated belly and humming softly to herself. Yes, this size would do. It was just about as big as Twilight’s and sat differently due to her womb carrying the majority of it, but that was where the differences ended. Although a part of her was disappointed at the fact that she wasn't bigger than her sister-in-law, the logical part of her brain was just happy the spell had worked as it wasn't intended to be used so often and in such a quick succession.
With only a hint of remorse, the mare lifted herself from her husband’s cock, waddled beside him and plopped down on her side, her belly facing him. She wiggled a little closer, pressing her cum-filled gut against him.
“Now are you done?” Shining Armor asked incredulously.
Cadance put a pensive hoof to her lips. “Almost, there is just one last pony that lacks a love-filled tummy.” The mare gently patted the stallion’s stomach, drawing a gulp from nervous male. Noticing his apprehension, Cadance frowned. “What, does my little Shiny not want to be big and full like his wife and sister?”
The male squirmed and looked away from his wife’s domineering gaze. “Maybe.”
Cadance smirked. “Well, I’m going to gather up all this yummy cum and if you won't have it then I guess it will just go to waste.”
The mare lit her horn, gathering all the spent cum the three ponies had expelled over the evening into one great swirling mass. As the ball continued to grow, Shining couldn't stop himself from licking his lips in anticipation. There were no specks of dirt, lint or anything else save for the pure white of their sperm. He wasn't sure how much of it was his, his wife’s or his sister’s, and something about that thought made him even more turned on.
Noticing the spell had finally completed, Shining gulped down the last of his doubt and opened his mouth wide, drawing an equally wide smile from Cadance who nodded approvingly.
“That's the slutty little stallion I remember, always eager to guzzle anypony’s cum.”
Shining’s face lit up in embarrassment, but he refused to look away, staring in awe as the great floating mass of cum came closer, slowly elongating as it made its way towards its final destination. The stallion shifted nervously on the bed, growing more impatient by the second.
When the now-narrow end of the floating cum made it to his lips, he had grown restless and, after the first bit of cum flowed down his throat, he couldn't resist and pushed his head forward, swallowing more.
Though usually such an act would earn a quick punishment any other day, now it only made Cadance grin with perverted intent. “Why didn't you say you were thirsty? I would have helped you sooner.”
Her horn grew brighter and the floating ball of cum flowed faster into the stallion’s waiting mouth, where it was eagerly gulped down, barely having the time to enjoy the taste before it flowed past his tonsils and into his gut, a gut that was growing by the second, all the while being gently rubbed by a soft pink hoof. His wife’s love filled him with warmth, figuratively and otherwise and he eagerly continued gulping down more of the seemingly-endless orb of cum.
His belly continued to grow and, though it wasn't reaching the level of Twilight’s or his wife’s, it was still impressive for him, and a silent part of him wanted to see it grow as large as theirs. But that was not meant to be, and before it could reach such a size, he gulped down the last few mouthfuls of cum, managing only to savor the very last one. He rolled the taste around in his mouth, picking out each of their respective flavors with the talented tongue of a connoisseur.
Twilight’s tasted slightly acidic, almost like vinegar, but with a much more palatable flavor. It reminded him of the one time he caught a raw mana bolt directly to the mouth during basic. He was thankful the acidity of Twilight’s cum was offset by the soft sugary goodness of his wife’s. She always tasted dreadfully sweet, but with Twilight’s addition it tasted… surprisingly good, and with the final addition of his own, richer taste it made quite the flavorful cocktail.
He swallowed slowly, noticing his wife staring at him. “Having fun?” She asked.
Shining swallowed harder, getting the last little bits of spunk stuck to his mouth. “A little.”
The mare giggled and pulled closer to her stallion. “Well, I’m glad you had fun. I know I did.”
Shining Armor turned and pressed his lips against his wife’s. “You are amazing, Cadey. I mean that from the bottom of my heart. Tonight was one of the best nights of my life, and something tells me this isn't the last time this will happen.”
She grinned innocently, summoning up a soft halo of light around her head which made the male snort with laughter. “Maybe.” She leaned in and kissed him softly. “But that's a thought for another day.”
He yawned suddenly, his body realizing just how tired it was.
Cadance pulled the blankets up and over their huge stomachs, only to frown when she realized it made an oversized tent, shrouding the male without giving him any of its comforting warmth. Her eyes lit up the instant an idea entered her mind and she wasted no time in telekinetically pulling Twilight closer, her large cum-filled belly sloshing audibly as it was pulled closer and laid slightly overtop of Shining Armor. Cadance quickly followed suit, draping her own belly over the other side of him and leaving him with a warm blanket of cum-filled mare belly.
Shining couldn't help but giggle at the silliness of it all, but he also couldn't help but admit that it was incredibly warm and rather cozy, even though he couldn't move much. He turned his head and gently pressed his lips against his wife’s.
“Goodnight, Shiny. Happy anniversary.” She whispered
“Goodnight, Cadey. Thank you for the amazing anniversary.” He whispered back before snuggling closer to her and closing his eyes.
