Chapter 1

Celestia shifted slightly, rolling onto her back as the sun creeping through the window played over her place. A lot had changed over the last two decades, not the least of which relinquishing her control of the dawn to her successor, but she was happy - well, mostly happy. Peering down at herself, down the valley of her heavy, mountainous chest, her eyes settled on her soft, bare abdomen.

She could freely admit that moving in with Shining Armor and Princess Cadance had been one of the best things she’d ever done, and it came with a whole host of benefits. Her pair of lovers saw to her marish needs, she continued living in the lap of luxury in spite of her abduction, and she’d been granted the gift of motherhood. She cherished her lovers and the family they cared for together more than anything - that said, her time with them had taken a curious toll on her.

It was commonplace for a mare’s body to change throughout pregnancy, gaining weight and growing to accommodate the foal within them, although there were always exceptions to the rule. Perhaps it was because they were both alicorns, or maybe it was due to Shining’s unparalleled virility and fondness for them - in either case, both herself and Cadance had retained their softened figures and heightened libidos long after they’d given birth. Sensing an all too familiar ache radiate from deep in her abdomen, she scrunched her snout.

Her daughter, now a proud young mare named Nova, was the light of her life, each day in the Crystal Empire was a blessing, and what few troubles she did have were quickly tended to. Her physical state was much like her mental well-being, that being perfectly fine and healthy by any measure, and she had nothing to complain about - nevertheless, as the days steadily passed with her pair of paramours, a ravenous hunger had started to gnaw away at her. She glanced to her left at Shining’s tranquil, slumbering face, smiled, and subconsciously drew a hand over her lower belly.

She would have liked to say that her time away from her throne was responsible for making her soft, plump and voluptuous in every conceivable way, yet she suspected there was something more at play than a relaxed lifestyle free of stress. Her bosoms were fuller than they’d ever been, her physique was soft and toed the line of being overtly overweight, and her hips were wide and made for bearing foals - foals she pined to have. Simply put, she yearned for motherhood once again, to feel the seed of life growing within her, and she wasn’t the only one.

As she thought back to when she’d been carrying Nova, a thrilled shiver ran up her spine. She couldn’t speak for every mare, having heard the complaints of aching feet, morning sickness, and bizarre cravings, she’d adored every moment of maternity. From watching her belly gradually expand to feeling her breasts grow sensitive and engorged with milk, every facet of becoming a mother had been wondrous - so much so that simply recalling those days was enough to send milk streaming from her hardening nipples while her marehood seized upon itself with anticipation.

Shifting her attention over, past the stallion’s face, she met her counterpart’s eye. Cadance peered back at her, smiling faintly and resting at their stud’s opposite side. She wasn’t the only one who’d been having the craving, the insatiable, primal urge to fulfill her purpose, and she was overjoyed to have such a capable and shrewd mare to conspire with. While she could have taken a direct approach, simply telling Shining that she wanted nothing more than for him to knock her up, there was something delightfully sinful about enacting a masterfully crafted ambush.

She gave Cadance a subtle nod and turned her eyes to the bedchamber’s door. Her horn glowed faintly, barring any unexpected and frankly unwanted interruptions while simultaneously layering a sound-dampening spell about the room. Though there was only a slim chance that anypony would come knocking, it was never a bad idea to take extra precautions - speaking of which…

While she silently worked, Cadance slowly and cautiously eased herself from the bed and tiptoed over to the dresser. They’d been planning this morning for months, taking their time and making preparations with the utmost care, and now all the pieces were in place. So long as they were able to leave Shining undisturbed until the right moment, it would be virtually impossible for anything to go wrong.

Carefully slipping her feet over the side of the mattress and to the floor, Celestia trotted over to her companion. “You said it came in yesterday?”

Cadance nodded as she pulled open a drawer and reached inside. “Yes. Zecora was a bit hesitant to craft it to our specifications, but I convinced her that she had nothing to worry about…”

“Perfect,” Celestia breathed, watching as her fellow Princess produced two vials of opalescent fluid.

Zecora was a potion maker of renown, one of the best in all of Equestria, and Celestia could understand her reluctance. An ordinary fertility potion would have been more than enough to ensure a mare ended up with a bun in their oven, so ordering a batch that was triple the usual potency was wholly unnecessary and bordered on reckless - thankfully for her, neither herself or Cadance were normal mares. At worst, the potent elixir would make them feel off for a day or so, but if it worked as they hoped - yeah, their little family would soon be growing by leaps and bounds.

Taking one of the proffered vials, Celestia uncorked the top with her teeth, offered Cadance a cheer, and downed the entire bottle with a single swig. The alchemical cocktail actually tasted pretty good, like honeydew and dragon fruit with a hint of mint, and it took her mere moments to feel the effects start to kick in. Within seconds, before she could even stash the emptied vial, a warmth radiated from within her stomach while her blood began to run hot.

The ache in her marehood intensified, her nipples stiffened, and her heart raced, but she wouldn’t - couldn’t take any time to savor it. With their potions imbibed, they moved on to the second phase of their carefully-laid plan. Trotting side by side, they sauntered into the lavish bathroom and pulled the door closed.

Celestia moved to one sink while Cadance stepped to the one sitting next to her. “It is a little silly…”

Opening a tube of lipstick, Cadance quirked a brow. “What is?”

“Putting on makeup and nothing else,” Celestia tittered, applying a touch of blush to her cheeks.

Cadance snickered and did likewise, doing herself up while completely and utterly nude. “Trust me, he’s going to love it…”

“Oh I’m sure he will,” Celestia noted, turning her attention to the mirror before her.

She’d been called the Princess of the Sun, although it would be more appropriate to call her the Princess of Maternity. While she wasn’t one to toot her own horn, she liked to think she looked irresistible. Taller and more curvaceous than any mare could dare to dream, she could and often would turn heads wherever she went, and she wasn’t the only bombshell of the castle.

Glancing over, she drank in the sight of Cadance. Nearly as tall as herself and almost as full-figured, the Princess of Love looked every bit as stunning as herself. Between the two of them, it was almost laughably easy to excite Shining, tempting him with their bodies, honeyed words, and the promise of sex that bordered on the divine, although that was hardly a bad thing. While he was a mortal, their adonic stud had aged like a fine cognac or scotch, getting better with age while retaining all the vim and vigor of his youth.

Her mind gradually wandered to his carnal skills, leading her to grind her thighs together. Holy heck - it couldn’t have been more than a handful of minutes, and she could already tell she was slipping into a deep, powerful estrus. Straightening up and giving herself one final once-over, she hastily brushed her mane and glanced to the door.

“Ready?” she inquired.

Cadance stepped around her and nodded. “On three ~ alright?”

Steeling herself, Celestia called upon her unfathomable arcane might. The elixir from Zecora would have been sufficient for them, inducing an ovulation and preparing them to both to be bred, but they’d agreed not to take any chances. As she focused her power and mentally recited the spellwork she’d spent the better part of a month studying, she closed her eyes and leveled her horn at Cadance.

“One…two…” she began as the soft sound of magic crept to her ears, “three.”

Though they’d both kept their voices low since getting up, neither of them were able to fully suppress a deep, guttural groan from escaping them as their sorcery was unleashed. A potent fertility ritual on top of a potion was, even for an alicorn, utterly ludicrous - then again, after sharing their mutual desire to get pregnant together, being prudent wasn’t going to hurt anything. With her knees buckling and marehood drooling, Celestia listed to one side and supported herself on the sink.

Cadance stumbled over and hugged the wall, softly panting while her tail flagged behind her. “B…buck…”

“Yeah,” Celestia wheezed.

She’d been turned on shortly after waking up, simply from knowing what morning it was, yet the one-two punch of magic and potion clouded her thoughts with pure, bestial lust. Stumbling to the door and throwing it open, only preventing it from slamming against the wall at the very last second, she waved Cadance onward. If her friend was as bad off as herself, it wouldn’t be a matter of if they lost control of themselves, but when.

Scampering ahead of her and to the foot of the bed, acting like a filly on Hearth’s Warming morning, Cadance placed one knee on the mattress and waved her over. Truth be told, between the spellwork and the elixir coursing through her veins, she was more than happy to get to the main event.

Moving in tandem, creeping up along either side of Shining, the pair paused and delicately pulled the blanket down his sleeping form. There’d been some heated debate on how to kick things off, with Celestia arguing that kissing and pillow-talk would be better than a ruthlessly sensual sneak attack, yet they’d ultimately agreed to skip the formalities and go straight for the throat. There was one thing that every stallion on the planet fantasized about, and so they’d decided to give him just that.

As the cover cleared his groin and unveiled his package, Celestia paused. Shining’s endowment was, in a word, perfection given form. Large enough to give her a good stretch and kiss her womb with every thrust, his length was more than enough to satisfy her. As she looked past the flaccid stallionhood and to his ripe, cum-laden balls, her mind raced.

He’d managed to put a bun in both her and Cadance’s ovens, twice in the case of his wife, and she’d soon be putting the twin cum-tanks he called balls to use yet again. She could have - would have gotten knocked up long before now, had she not made use of contraceptive magic, so she was absolutely, unquestionably certain that she wasn’t going to leave the room that morning without a thick, virile load in her foal factory.

Unable to control herself any longer, she lowered herself, inched forward, and brought her snout to his loins. She would have though that being with him for so long would render her immune to his scent, but she couldn’t have been more wrong. Thick, heady, and downright intoxicating, his stallionly musk alone made her marehood wink.

Cadance was no better off than herself, breathing deeply of his natural fragrance while sandwiching his thigh between her impressive rack. Kissing his way over his hip, she touched her lips to the thick folds of flesh at the root of his tool and softly moaned. She could have stayed like that forever, simply basking in the masculine aura of his nethers, although she, like herself, knew they couldn’t dither for too long.

While Shining wasn’t the lightest sleeper, every moment wasted was one they risked having him spontaneously awaken - as such, they waded through their welling lust and put themselves to task. Drawing their tongues over and around his shaft, they lavished him with mute affection. After what couldn’t be more than a few seconds, the behemoth that was his cock gradually roused from its slumber.

Swelling with every beat of his heart, his stallionhood rose and came to life. Simply watching him get hard was a stimulating experience, seeing him to from a soft, albeit comically large noodle to the rigid mare-breaker that was his pride, though neither mare stopped to savor it - if anything, sensing him harden against their tongues and pouting lips spurred them onward. All but making out around his shaft, they each shifted a hand to cradle his plump, fuzzy nuts.

If he’d been up, he would have surely appreciated the view ~ why would he not? He was the only stallion in Equestria, possibly all of history, who had a duo of alicorns as lovers. Any remotely straight guy would have killed to be in his place, and that was just for the oral! With what the Princesses had in store for him, he’d forgive them for worshiping him while he quietly dozed.

Stopping as they reached the tip of his stallionhood, the duo stopped and locked eyes. Though every detail of the morning had been meticulously charted, there was one element that would be left to chance - which of them would have the honor of sucking him off. Pulling away from his now towering length, they balanced on one arm while lifting a fist to one another.

Clamping her eyes shut and setting her jaw, Cadance cursed under her breath. The match of rock-paper-scissors was over in a flash, and now she’d have to deal with losing to her friendly competition. Leaving Celestia where she rested, and ignoring the smug, victorious look on the mare’s face, she continued up the bed and closer to Shining’s head.

Celestia wanted until Cadance was in position before picking up where she’d left off. She repositioned herself quickly, taking a more ideal spot to tend to Shining’s endowment, while her counterpart made herself ready. Once they were both prepared, signaling one another to commence their full attack, they struck with everything they had.

While Cadance aggressively kissed and pawed at his chest, she wrapped her lips around the tip of his cock. The assault was dastardly, downright villainous, and it worked like an absolute charm. Blinking his eyes open and lifting his head, Shining peered down his body in bewilderment, went motionless, then smiled broadly. Nothing quite says I love you like a good morning blowjob and the affection from a duo of MILFs.

“Well then,” he began, stifling a yawn, “it looks you two are feeling frisky…”

“Mmmhmm,” Cadance hummed, plastering her bare tits against him while running a small circle about his nipple.

Shining grinned as he looked between his pair of lovers. “Is this a special occasion or…”

He trailed off and let the question hang. There was a reason he’d worked his way up to being a captain of the Royal Guard, caught the eye of not one but two alicorns, and had successfully protected both Equestria and the Crystal Empire for years on end, and it wasn’t because of his incredible endowment. Ever the shrewd stallion, he likely suspected that the two-pronged attack hadn’t been flawlessly executed just for fun.

Dragging herself up his supine body, Cadance brought her muzzle to his ear. “Celestia and I have been talking…”

Waiting for her to continue while Celestia nursed on his stallionhood, he ultimately realized his wife would need a bit of coaxing. “A dangerous thought. Please, continue.”

Cadance glanced back to her nightstand, ignited her horn, and opened the top drawer. “Maybe this will explain it.”

As she levitated a small bottle up and over to him, his eyes widened after he squinted at the label. “Really?”

Celestia pulled back and freed her muzzle with a faint Pop. “Though we are ageless, there’s no time like the present.”

The second she finished talking, she continued sucking him off with renewed vigor. In addition to the magic and alchemy she and Cadance had used on themselves, they’d mutually agreed that enhancing Shining’s virility would guarantee success. Was it overkill to set their reproductive organs into overdrive by an order of magnitude? Arguably, yes. Would that stop them from pushing the envelope? Not in the slightest.

“I - Nnnph,” he grunted as his cock-head slipped into Celestia’s gullet. “I g…guess we could give Flurry, Nova, and Aegis new little brothers or sisters.”

With the vial floating into her palm, Cadance removed the cap and brought it to his lips. “Just what I was hoping to hear…”

As her throat bulged from the immense intrusion, Celestia summoned her magic. As with themselves, Shining wasn’t just going to have the aid of alchemy. Putting her sorcery to work, she gently poured power into his balls. While there wasn’t much of a physical change to his impressive coin purse, the quantity and potency of his seed would steadily increase for the next few hours.

“There we go,” Cadance purred, tossing the empty bottle away. “Now give mama some lovin’, stud…”

Seeing the pair start to make out, Celestia closed her eyes and fixated warming him up. The taste of unwashed flesh dancing over her palate, his scent clinging to her sinuses, the sound of the couple kissing, the feeling of his mighty stallionhood swabbing her throat - everything about the exchange was exquisite. She shifted as he spread his legs for her, making himself more accommodating and allowing her to get into a better position.

While she had intended on blowing him, she knew an opportunity when she saw one. Sideling between his thighs, she placed her elbows to either side of his hips, sandwiched his dick in her cleavage, and suckled on the tip of his length. Years of experience had shown her how much he liked to be involved, so letting him take an active part in the opening act was the least she could do.

Sure enough, as soon as she crushed his stallionhood between her tits, he planted his feet and started thrusting. The position would have made fully throating him impossible, given that most of his endowment was entombed by her rack, but he didn’t seem to mind. Holding herself steady and letting him do the lion’s share of the work, she lowered her hands to tweak and twist her nipples.

She’d never been overly fond of having her tits played with, before she’d entered the polyamorous relationship with the royal couple, but time had changed that. Warm milk sprayed over his abdomen and the bed, vying for his attention while his tongue sank into Cadance’s snout. Her eyes never wavered from his face, catching every glance he shot down at her, while her preternatural heat grew more and more intense.

The three took their time, but that was hardly new. Most of their escapades were like this, steadily becoming increasingly heated until somepony’s composure broke. A gentle caress, a sexual moan, a light squeeze here or there - they all knew exactly what was going to happen, even if none of them could predict whom would break first.

Using her lips and tongue to mop his length clean, Celestia could feel her hips twitching. The burning desire to be filled, to be bred, clawed at her sanity and made it difficult to think - worse still, the rhythmic contractions of her marehood were becoming unbearable. She held back until she could stand it no longer, only reluctantly pushing herself and clearing her muzzle of his shaft.

Shining broke his kiss and looked up as Celestia shuffled forward on her knees above him. “That was fast…”

Without skipping a beat, Cadance leapt into action. Getting to her knees and swinging one leg over his head, she straddled his face and peeked down at him. “How about you stop flapping those gums and warm me up.”

“Yes ma’am!” he chirped.

Eagerly grabbing her waist, he lifted his head and feasted on Cadance’s loins. The sight of him eating out his wife was hot, but Celestia could scarcely appreciate it. The devastating combination of elixir, spellwork, and hormones flowing through her system were devastating. In that moment, despite being thousands of years old, she was little more than a lust-crazed beast.

She reached back, clutched his cock, and guided it to her entrance. If she didn’t get fucked soon, she wasn’t sure what she was going to do - mercifully for her, she didn’t have to wait for long. Feeling the tip of his length kiss her entrance, she threw her weight down and impaled herself in a single, brutal plunge.

Her eyes rolled wildly, her tongue lolled out of her mouth, and she howled in unfettered ecstasy as she came instantaneously. She never could last all that long with him, regardless of the specific circumstances or how many climaxes she’d had prior, although this may have been a new record for her. Trembling and gushing nectar over his groin, she took a moment to collect herself and savor the spontaneous climax.

Sex with him and Cadance was easily the best she’d ever had, and each experience was as wondrous as the last. Though she couldn’t truthfully say the amorous affection of the pair would ever grow dull, the past two decades of living with them had only seen her appreciation for them grow. As something delicately pinched her nipples, she was wrenched back to the present.

“B…buck,” she rasped, looking over into Cadance’s eyes.

Cadance smirked while she gyrated her hips and ground her marehood against Shining’s face. “Don’t milk him too dry.”

Using her wings to balance herself, Celestia leaned back and started to move. She clenched on her ascent, squeezing Shining’s length in her silken depths, and slowed when she reached the head of his cock. She wasn’t going to go too overboard with him, but she was already looking forward to the familiar sensation of his essence surging into her.

It took her no time whatsoever to fall into a steady rhythm, hammering her ass down on him while he thrust up to meet her descents, yet she had more than just the two of them to think about. Fighting through her bliss and extending her arms, she cupped and fondled Cadance’s breasts. While the Princess of Love wasn’t quite as gifted as herself in the chest department, the nubile alicorn’s body was extraordinarily alluring.

Cadance returned the favor, playing with her heaving tits as she rode her husband’s face. Unlike herself, who had the body of a maternal goddess, her fellow royal’s figure was like that of a model. More slender and toned than herself, the young Princess was the sort of mare that sculptors sought to immortalize in marble.

The air grew thick with the scent of arousal and sweat, hushed moans and sinful whispers echoed throughout the chamber, and the trio gradually moved faster and faster. It was a dance they’d done more times than they could count, and yet it never grew tiresome. While Celestia had been the first to peak, she would be far from the last to do so.

To Shining’s credit, he gave as good as he got, dining on Cadance’s marehood while plowing Celestia from below. He may not have looked much different from a normal stallion, massive endowment notwithstanding, although his endurance and strength were unparalleled. Sneaking one hand around his wife’s waist, he blindly quested for her clit.

Shuddering and lurching forward, Cadance leaned against Celestia for support. Her breaths grew ragged, her thighs quaked, and the pitch of her voice raised an octave. Like her senior noble, she reached her limit with startling speed and cried out in rapture.

Celestia hastened her pace, yearning for more and inspired by Cadance’s outburst. Rolling her hips forward and back, relishing the feeling of Shining’s medial ring grinding against her g-spot, she gnawed her lower lip. Save for wishing she’d joined them ages earlier, she hadn’t regretted a single moment of being with them.

Her second climax struck almost as suddenly as the first, hitting her out of the blue and causing her to bray uncontrollably. She would have fallen, toppling from him before he had a chance to finish, but she was lucky enough that Cadance had recovered enough to catch her. Shakily lifting her head, she peered into Cadance’s eyes.

With their tits smashed together and faces mere inches apart, the pair shot forward and deeply kissed. They loved Shining dearly, neither would contend that, although they cherished one another just as deeply. There’d been times when just the two of them would fool around, if only because their mutual stud wasn’t available, and such instances were incredibly rewarding.

Shining grunted into Cadance as his pace hastened. After being caught off guard so early, and having made two alicorns climax in relatively short order, he was reaching his limit. With his stallionhood throbbing in tune with his racing heart, he plowed Celestia with everything he had.

Simply feeling him flaring within her was enough to push Celestia past the brink a third time, and envisioning what was to come evoked a fourth climax by itself. She had no way of knowing exactly how long they’d been going at it, be it seconds or years, and the fact that she was about to get her reward was bittersweet. On one hand, she yearned to feel him flood her womb - on the other, she could ride him for ages.

Seconds slowly passed, stretching into an eternity, until it happened. Shining arched his back and hilted her, burying every inch of his shaft as his stallionhood began to pulse. Wave after wave of rich seed erupted into her, giving her what she craved so dearly, but she couldn’t appreciate it. No sooner had the first shot of his foal-batter bathed her depths than she came with apocalyptic force.

Celestia couldn’t move, she couldn’t think - merciful Tartarus, she could barely breathe, so great was the overwhelming ecstasy that consumed her. Though her higher functions were gone, the most primitive parts of her id knew she’d been impregnated right then and there. Wracked with one orgasm after another, only vaguely aware of her limbs going slack, she tried and failed to stave off oblivion.

She’d done a great many things over the centuries, but this was the closest she’d ever come to blacking out from pleasure. Landing with her face on Cadance’s rack, she fought to catch her breath while the world spun around her. Her limbs felt like they were made of lead, her heart threatened to pound through her chest, and her quivering marehood sent aftershocks of ecstasy through her. Stars above - had she known the combination of sorcery and alchemy would be this divine, she would have used them long before now.

“Hey,” Cadance murmured, cradling and lifting her face, “you ok?”

“Uh…uh-huh,” Celestia drunkenly slurred.

With her blurred vision and addled mind clearing ever so slightly, she languidly went to dismount Shining. What should have been a simple affair turned herculean - no, downright impossible, leading her to crash unceremoniously to the mattress beside him. She landed on her side, rolled to her back, and stared up at the ceiling.

“H…holy cow,” Shining gasped, tearing her from her stupor.

Glancing over at him, she followed his gaze and froze. Her belly, normally only the slightest bit doughy, had rounded by a noticeable degree. She’d had no doubt that he’d filled her with a phenomenal load, yet she’d underestimated just how productive the potion and magic cast upon him had been. It wasn’t like she’d been creampied by a single stallion - far from it, it appeared as though she’d played paternity roulette with dozens of studs in rapid succession.

She reached down with a shaking hand and caressed her abdomen in awe. The fullness, the sensation of being bloated with foal-batter was the icing on the cake - well, no, more like icing in the cake, but that was neither here nor there. As she envisioned just how knocked up she was going to be, possibly with triplets or quadruplets given his prolific output, she peeked over as the couple giggled.

“My turn!” Cadance whooped, shoving Shining aside and scrambling over her.

Celestia remained motionless - not just because she was too weary to budge but because her body refused to obey her. Cadance mounted her head, lurched forward, and settled herself on her hands and knees. The view of the younger mare’s pussy was breathtaking, although that wasn’t what held her rapt attention.

Turning her head, she watched as Shining eased himself from the bed, stepped around, and situated himself directly behind his wife. Be it by fate or pure dumb luck, she’d fallen widthwise across the mattress, giving her a front row seat for the impending rutting. Drooling from both ends, feeling his essence seeping out of her, she threw up a hand.

“W…wait,” she croaked as her horn sputtered to life.

The last thing in the world she was going to do was stop them, but there was something she had to do first. Casting a simple spell on herself, she sealed her depths and trapped what had to be several pints worth of jizz in her womb. Letting his seed marinate was yet another extra step to make double-triple sure she wound up with a bun in her cum-starved oven - at least that’s what she told herself; in truth, she wished to relish his rich spunk for as long as possible.

Hearing Cadance mewl out, she gazed up in awe as Shining sank his colossal mare-breaker into his wife. The view was nothing short of spectacular, the aroma of his musk and Cadance’s sex were like a fine wine, and she shivered knowing just how amazing it was to be taken in such a way. While nopony would have blamed her for taking a breather to recuperate, she couldn’t bring herself to sit idly by.

She dove into the action without the slightest shred of hesitation, licking the cum and marish juices from Shining’s pistoning length. The cocktail of Cadance’s nectar with her own, accentuated by his jizz, made her marehood throb. Gliding one hand down her belly and to her loins, she parted her thighs and wantonly got herself off beneath the pair.

If she hadn’t known that Shining and Cadance were rulers of the Crystal Empire, she could have mistaken them for porn stars. Both the ponies were easy on the eyes, well-built, and in their prime. She was a bit surprised that they hadn’t had more children, considering how much they loved one another and their young, but that was going to change soon enough.

“I…I’m g…gonna,” Cadance wheezed, quivering like a leaf in the wind.

Celestia closed her eyes and opened her maw, prepared for what was coming. A shriek of rapture was followed instantaneously by a baptism of sweltering juices, bathing her face and flowing into her maw. There were mares out there who would have balked at such a development - fortunately for everypony involved, she was not one of them. With the flow of nectar tapering off, she adjusted her head and suckled on Cadance’s clit.

The Princess of Love writhed in torturous bliss, climaxing at least another two times in mere seconds. While she did feel a little guilty for accosting her friend in such a way, it was only fair - after all, she’d been subjected to such treatment by the young royal on more occasions than she dared to count. Shining chuckled above her as he tightened his grip.

Shining’s thrusts grew harder and faster, driving his wife forward and causing her to fall onto her chest. He was a magnificent specimen of a stallion, healthier and more virile than a great many who were younger than himself, and he had many, many years ahead of him. Between the wonders of modern potion making, magic, and enchanted artifacts, he would be with his Princesses for centuries to come.

Only slowing when she climaxed herself, bucking into her hand while massaging her clit, she watched as Shining drew closer and closer to his limit. He actually lasted for quite an impressive length of time, pushing his wife to one orgasm after another, although he wasn’t without his limits. Sinking his fingers into Cadance’s waist, he hilted and roared out as he came.

Simply seeing the underside of his shaft pulse, watching shot after shot of his essence being pumped into Cadance, was enough to push Celestia past the edge for - well, honestly, she’d lost track of how my climaxes she’d had. Quickly enacting the same spell she’d cast on herself, trapping his seed within the whimpering Princess of Love, she smirked. Yeah, there was no doubt about it, they were both going to be mothers after this.

Falling to her side, Cadance gasped for breath. “I love - COUGH - both of you.”

“Love you too, Sweetie,” Shining coolly responded. Mopping his brow and unsheathing his still rigid length, he walked around the bed, grabbed Celestia’s ankles, and pulled her to the edge of the mattress. “Come here, you.”

Yelping in surprise, Celestia gazed in wonder down at him. “W…what are you -”

“Round two,” he interrupted, leaning forward and driving her ankles to either side of her head.

“I…w…wha…” Celestia stammered, caught completely unawares.

To see him go for a third round so quickly was unprecedented - heck, even with the arcane and alchemical enhancements he’d been given, she was taken aback! Effectively immobilized, having her arms pinned beneath her legs while he bore down upon her, she swallowed hard. She and Cadance had told him they wanted to get knocked up, they’d planned this morning for several months, and they had nopony to blame but themselves for his determination - nevertheless, to be dominated in such a loving way was humbling.

After rolling his hips back and getting into position, he began railing her with reckless abandon. She’d warmed him up and fucked herself on him, and now he was going to give her her reward. While there was nothing wrong with being on top, nothing - nothing beat getting plowed by a stud of his caliber.

Her mind went blank, she squirmed helplessly beneath him, and streaks of saliva crept from her open, howling snout as she came over and over and over again. She lost track of how many climaxes she endured as her sanity fractured and waned under the incalculable weight of pure ecstasy. This wasn’t making love, the tender caress of somepony who cared for her - this was raw breeding, and it was what she needed.

As she weaved in and out of consciousness, he conquered and used her like a toy. Though she was older, taller, and stronger than him in every appreciable way, she was a mare - a mare in the throes of a wholly unnatural estrus. Her place was beneath him, a loyal subject to bear him as many offspring as he so chose, and he was the only one who ever had or possibly ever would win her over in such a way.

His rutting was merciless, stretching on for an incomprehensible period of time, and it broke her on a fundamental level. Drowning in a sea of pleasure, she only regained a sliver of her higher self when he gave her a particularly hard thrust. Driving through her cervix and into her cum-filled womb, his stallionhood flared and locked itself in her deepest depths.

While she’d gotten close to blacking out while riding him, the act of having him cum straight in her foal-factory undid her. Her vision tunneled and her mouth hung open in a silent scream as oblivion claimed her. It was the perfect ending for a marvelously depraved morning, one she wouldn’t soon forget, and it marked the beginning of a new chapter in her life. No matter what happened next, irrespective of how the rest of her day went, she was absolutely, unquestionably sure that Cadance and herself would soon be visiting Rarity for some new maternity attire…

Chapter 1.5

Appearing with a flash of light and pop of displaced air within the Carousel Boutique, Celestia opened her eyes. The shop was dimly lit and vacant, bereft of customers or employees, though she wasn’t paying a visit at such an odd time for no reason. As her ears perked up at a noise coming from the employee area behind the counter, she grinned.

“Knock knock,” she called out.

“Just as expected, you’re right on - goodness gracious,” Rarity gasped, trotting out from her studio and coming to a screeching halt.

Celestia’s cheeks darkened as the couture stared over at her open awe. There was a very specific reason she’d explicitly asked Rarity to come after hours for her order, but she hadn’t been as forthcoming with details as she could have been. While she had told her friend that she was pregnant and that she’d be requiring some new maternity attire, she’d failed to explain why she desperately needed a few new garments.

Glancing over at a standing mirror, she sighed. She was positively gravid, her stomach so large that one could easily assume she was carrying triplets, and her breasts - heavens be, her heavy, milk-laden bosoms were the size of small beach balls! Each gargantuan breast was engorged and virtually spilled out of the makeshift toga she’d fashioned for herself, and she knew they’d only get larger as time progressed.

To make matters worse, as if having an even larger rack and huge belly didn’t complicate life in the Crystal Empire, she’d put on a considerable amount of weight. Her tush was bigger and softer than ever, devouring even her most conservative panties and transforming them into thongs, while her pudgy thighs strained any leggings or stockings she slipped on. She’d known it would only be a matter of time before doing some clothes shopping, but even she hadn’t realized how quickly her wardrobe would require new additions.

“You failed to mention that you were in - Ahem - such a state,” Rarity falteringly clucked, struggling to compose herself as she trotted over to her.

Turning in place, she lowered her gaze past her heaving bust. “Yes, w…well it’s a bit complicated.

Rarity peaked a brow and scrunched her snout. “Complicated. Darling, you’ve had at least seven months to -”

“Two weeks,” Celestia interjected, simultaneously amused and embarrassed by the mare’s stunned expression.

“I…h…how - two weeks?” Rarity croaked. “There’s no possible way that -”

Blushing harder than ever, Celestia held up a hand. “I wouldn’t lie to you, Rarity. As silly as it may sound, this,” she explained as she caressed her abdomen, “is the result of, shall we say a bit of overzealousness on my and Cadance’s behalf…”

Rarity reluctantly turned and waved for her to follow. “I would never assume you’d lie to me, Celestia - be that as it may, I’m curious about…”

Trotting along after her, Celestia uneasily chuckled. “About how this happened?”

“Quite,” Rarity whispered, pressing into her workshop and over to her drafting table.

Celestia walked in and veered slightly to her right. Coming to a stop at an open area of the floor, she grunted and ran a hand over one shoulder and to the knot securing her improvised attire. Wearing a bed sheet around, while comfortable and serving to retain her modesty, wasn’t the most elegant way to dress, but it was the only option she had.

“It’s not that grand of a story,” she began, shrugging the toga off herself.

While Rarity prepared, flitting about to gather measuring tape, pinking shears, and a few bolts of fabric, she recounted the passionate and admittedly ambitious scheme Cadance and her had enacted. Rarity, much to her credit, remained silent throughout most of the tale, until she sauntered over with a cart laden with the tools of her trade.

“I’m not that surprised that you and Cadance would want to be mothers again, although you seem to have gone a bit overboard - no offense,” Rarity laughed.

Celestia extended her arms to her sides and held still as the mare levitated a stepping stool over. “None taken, but you know what they say about hindsight being twenty-twenty.”

“Hold this,” Rarity instructed, holding the end of her measuring tape to Celestia’s naval. “I presume the maternity ensembles I fashioned for you have long since been discarded?”

“It’s been roughly two decades,” Celestia pouted, turning her head to watch the mare circling her. “For the record, I didn’t discard them.”

Coming around to her front, Rarity completed the one measurement and jotted it down on her clipboard. “Charity then?”

Celestia nodded. “Actually yes. The proceeds went to a hospital.”

“Well I hope they went to the maternity wing,” Rarity laughed as she stepped onto the stool.

Snickering at the joke and genuinely wondering if some of the funds went for such an apt purpose, Celestia held still. It was far from the first time she’d gotten a fitting, and it assuredly wouldn’t be the last, yet having her bust measured was always a bit of a delicate affair - especially under such unique circumstances. Keeping her arms extended out to either side, she watched Rarity struggle to wrap the tape around her expansive chest.

“Would you like me to…?” she let the question hang and shivered as the mare’s face practically disappeared into her cleavage.

“Mph nnnnf mmph nf!” Rarity replied, her words muffled by the exorbitant amount of breast meat surrounding her head. She ultimately pulled away with an exasperated look and pursed her lips. “Are they even bigger than last time? I could swear they weren’t this prolific.”

Prolific - the word resonated with Celestia and sent a shiver up her spine. Several days prior, she’d realized exactly why her bosoms had ballooned to such an absurd size. Recalling how Shining had discovered that, irrespective of how early in her pregnancy she was, she had already become as productive as a dairy cow, she glanced to her right nipple.

Right on cue, seemingly knowing it was being looked at, the delicate bud of rigid flesh leaked a drop, then a small stream of milk. Fantastic - just wonderful. She wasn’t particularly bothered by showing her bare body to a professional like Rarity, but spontaneously lactating while having her measurements taken was a bit awkward.

Rarity stiffened as small jets of milk sprayed from one teat and then the other, showing the floor to either side of her. “Stain resistant, waterproof, and with adequate dimensional folding to accommodate some growth,” she murmured as she scribbled upon her notes.

“Extensive growth,” Celestia added. “Considering I’ve got months ahead of me, I’d much rather err on the side of caution when it comes to my attire. I do have a question though - that dimensional folding you mentioned, might you teach me how to do that?”

Peeking up at her, Rarity smiled. “Of course, darling! It may seem like a complex enchantment, but it’s actually shockingly simple. After we’re finished up here, I’ll jot down a few notes and fetch you a book detailing the process.”

“I’d appreciate that,” Celestia mused as an idea began to coalesce. “Just to be sure, you should double the space for my bust…”

“Double - no, quintuple the space,” Rarity stated as she rewrote and underlined the last line she’d jotted down. “It couldn’t hurt to -”

Grrrrrrr

Celestia froze and her attention sailed downward and to the source of the sudden noise. With a flustered expression, Rarity anxiously laughed and batted a hand. No way - there was no way that the two fountains of milk showering from her breasts had given the mare hunger pangs ~ could they? Entertained by the notion that she’d unintentionally triggered the normally demure mare’s appetite, she clutched one of her tits in both hands and gave it a small squeeze.

The flow of her milk amplified into a geyser, practically pouring from the held bosom while she giggled. “If you’re feeling peckish, you could - you know…”

She’d merely meant it as a joke, seizing the moment to fluster her friend and break the tension from what would otherwise be a somewhat uncomfortable moment, but her plan backfired spectacularly. Instead of brushing off the offer or making light of the situation, Rarity licked her lips and gazed longingly at the gushing bud of flesh. Though she should have stopped things there and urged the mare to continue where they’d left off, the thought of being nursed upon made her marehood wink.

“I…I mean…” Rarity trailed off, struggling to avert her gaze while she rubbed the back of her neck.

Angling her tit over and relaxing her grip, Celestia giggled. “Come now, it’s not like Shining or Cadance would mind - besides, I’d rather somepony drink it than let it go to waste.”

She stepped back, released her breast, and brought her forearms together over her chest to press her bosoms together. To Tartarus with it - she’d done more scandalous things over the millennia than letting a friend nurse from her. Playfully swaying her shoulders from side to side, she mutely pressed her offer.

“Oh buck it,” Rarity halfheartedly groused. Closing the small gap between them, she paused, looked up, and lifted a finger. “Not a word of this to anypony ~ promise?”

“Only if you swear to do likewise - oh and don’t be shocked if I make a bigger mess,” Celestia whispered, sensing an ache steadily growing in her loins.

Being pregnant, regardless of at which stage, was a blessing and a curse. The added weight, bizarre cravings, and occasionally sore feet weren’t that bad, but her insatiable libido could and at times had caused a number of problems. She’d had all sorts of wild experiences throughout her life, although there were few things more torturous than having to maintain her composure throughout a meeting while being painfully aroused.

“Very well,” Rarity responded, “but you’re going to help clean afterwards.”

Celestia nodded and sent power surging into her horn. If they were going to indulge themselves in such a spontaneous way, she wasn’t going to cut any corners. The golden aura surrounding her clit and radiating into her depths went unseen, but it would be just the thing to let her fully enjoy a pair of luscious lips upon her.

Casting her reluctance to the side, Rarity stepped back onto the stool, leaned over, and latched onto her nipple like a starved child. She wasn’t sure what was hotter - the fact that her friend and a hero of Equestria was sucking on her breast or that it felt absolutely amazing. Her tits had always been a weak point of hers, and she loved having them played with while making love to either Shining or Cadance, yet they became leagues more sensitive when she was lactating. Surreptitiously using her magic to get herself off, she slipped a hand to the back of Rarity’s head.

As she closed her eyes and savored the blissful sensations washing over her, her thoughts drifted into amorous waters. She couldn’t say if things would stop with Rarity nursing on her, but she hoped they wouldn’t. The relationship she had with Shining and Cadance was somewhat open, allowing them to include a fourth in the bedroom at times, and she wouldn’t be opposed to bedding an Element of Harmony.

Regardless of how things played out at the Carousel Boutique, the morning was a reminder of the long, lustful road ahead of her. Shining had been lucky all those years ago, essentially only having to deal with one gravid, horny Princess at a time, but now he was going to have to weather the advances of Cadance and herself for the better part of a year. Fixating on the passionate night she’d been knocked up, she softly groaned.

Glancing over at a nearby mirror, one that appeared to have been pulled from a dressing room, she marveled at the spectacle she was making. Rarity was voracious, gulping down mouthfuls of milk like she hadn’t eaten in days, and the bottom of her blouse was already rounding from the impromptu meal. Refocusing her magic just a touch, if only to make her host a bit more comfortable, she unbuttoned the mare’s shirt and pants so she would give herself a bit of a peep show.

The view was spectacular. Rarity’s soft, gradually rounding belly and bra contrasted sharply against her curvaceous physique, but that wasn’t what drew her eye. Her areola, normally a light pink, had darkened and grown considerably since she’d begun producing. Now larger than a pony’s head, the dark, delightfully tender patches of skin on her tits stood out more prominently than ever.

Rarity lifted an arm, pawed at her free breast, and lovingly pinched her unaccosted nipple, causing her faint moan to elevate into a whimper. The normally reserved seamstress knew exactly what she was doing, and the added bit of stimulation was just the perfect complement to the staggeringly lecherous exchange. As she tightened her grip and weaved her fingers through the unicorn’s mane, a smile split her muzzle. Yeah, the next couple of months were going to be very, very interesting…

Chapter 2

Knock Knock Knock-Knock Knock

Having rapped on the door of the Castle of Friendship, Shining stepped back and smiled over at Cadance. “Been a little while since we’ve been here ~ huh?”

Cadance nodded as she peered up at the towering, crystalline keep. “Too long - then again, it’s not like Canterlot doesn’t keep her busy.”

Shifting her weight from one side to the other, she waited alongside her hubby at the entryway. She would have liked to say that the visit with Twilight was just for fun, but there was a bigger reason for going to see her sister-in-law - a big reason. Peeking down at herself, she lifted a hand and caressed her distended belly.

Like with Celestia, her pregnancy had been progressing much, much faster than normal - to the point where, if for no other reason than to have some peace of mind, she’d decided to seek Twilight’s input on the matter. Even though she felt perfectly fine and had been given the all-clear by not two but three of the finest maternity doctors in all of Equestria, having one of the foremost experts of magic give her a once-over wouldn’t hurt anything - that and it was an excuse to spend some time with one of her oldest and most trusted friends. Hearing footsteps rapidly approaching the foyer from just inside, she locked arms with Shining and shied back.

“Shining, Cadance, I’ve been looking forward to…” Twilight began and subsequently trailed off as she flung the door open and gazed out at the couple.

Without skipping a beat, not caring that her friend’s focus had been torn between her mountainous bosoms and rounded stomach, Cadance shot forward and snared the mare in a hug. “I’ve been looking forward to seeing you too!” she chirped, entombing the smaller Princess’ face in her cleavage. Pulling back as quickly as she’d started, she quirked a brow. “Somepony’s hitting their alicorn growth spurt!”

Being the youngest alicorn and only having recently ascended, it would be some time, possibly centuries, before Twilight reached her or Celestia’s size. As she gazed down at the mare, she couldn’t help but marvel at the disparity between them. In an ironic sort of way, there wasn’t much that had changed since her days of foalsitting the little, nerdy mare so many years ago.

Twilight’s appearance was striking in its own right, having a modest chest, meaty thighs, and a respectable rump, but she looked downright flat-chested compared to herself. The weight she’d packed on had filled out her figure substantially, her caboose struggled to fit in most chairs, Her tits were roughly the size of small beach balls - speaking of which…

Twilight tore her eyes off Cadance’s chest and blushed. “W…well - ya know, maybe a little…”

“You have gotten a bit bigger,” Shining laughed, throwing his arms wide and embracing his sister. “Just look at you, you’re almost as tall as I am!”

Giggling like a schoolfilly, Cadance watched as Shining placed a hand on his head and inaccurately brought it over Twilight’s crown. Though he was shorter than her by two or three inches, it was endearing to see him still acting like the bigger bigger brother. While the siblings playfully bickered about who was taller than who, her eyes wandered down Shining’s back and to his deliciously toned tush.

A subtle ache crept into her marehood, she could feel her nipples hardening against her bra, and her pulse steadily increased as an assortment of very inappropriate images danced through her head. While Shining wasn’t as young as he used to be, having white peppered through his azure mane and tail, he was still a paragon of virility. His broad shoulders, his youthful exuberance, and his long, thick, incredible…

“L…let’s get inside,” she stammered, shaking the intrusive and scandalous notions from her head.

Walking inside after Twilight and Shining, she pulled the door closed behind herself and gave a sigh of relief. Being carrying a foal was, in a word, one heck of a roller coaster, although this pregnancy was different from her last two in a number of ways. For starters, she’d ballooned in size way faster than she should have - secondly and a bit alarmingly, her hormones had been running absolutely wild. She was a healthy, passionate mare by any metric, yet her libido hadn’t been so strong since she’d been a rambunctious teenager - heck, it may have been worse than when she was a teenager.

Twilight trotted ahead with Shining at her side, and led the way. “And you said this all started two months ago?”

“A month and three weeks, but who’s counting,” Cadance tranquilly replied.

Glancing back at her, Twilight narrowed her eyes. “You know I’m going to need to know the details ~ right?”

Visibly stiffening, Shining nearly stumbled over his own feet. “A…all the details?”

“All the details,” Twilight flatly repeated. “Listen, I may not be a medical doctor, but I won’t be able to make heads or tails about what’s going on unless I can account for all the variables - oh, and I’m going to need to perform an exam and get a few samples.”

“Samples?!?” Shining squawked. “Twilight, I am not about to -”

“Shiny, it’s fine,” Cadance reassuringly murmured, striding up to his side and placing a hand on his shoulder. “Twilight, I’m sure you didn’t mean you wanted to collect the samples yourself.”

Twilight’s wings flitted out to her sides as her cheeks darkened. “What? N…no! Ew!”

“See,” Cadance snickered, “there’s nothing to -”

“I…I mean, I could get some from you, Cadance - like, if - Ahem - you n…needed some help or something, but I w…wouldn’t want to get anything from my BBBFF!” Twilight interjected, anxiously stuttering and playing with her hands. “I’d have to be crazy to even look at Shining - n…not like he l…looks bad or anything - ya know, because he’s so -”

“Twilight,” Cadance interrupted, sideling over and hugging the flustered mare from behind. “Maybe we should drop it for now.”

“R…right,” Twilight grumbled.

It took everything Cadance had not to laugh at the exchange - not just because Twilight was so out of sorts, but because Shining wasn’t any better off than his sister. Blushing heavily and anxiously sweating, he kept his lips sealed while lagging behind. She’d long suspected that the siblings’ affection for one another was slightly atypical and involved something more than the platonic, but she hadn’t, nor did she have any intention of openly questioning the matter.

Descending into the bowels of the castle, one of the few areas Cadance wasn’t familiar with, Twilight opened and sauntered through what appeared to be a heavy blast door. “Sorry in advance, it’s been a while since I’ve been down here.”

Cadance walked in after Shining and drew to a halt as the room went alight. She’d known Twilight was a science buff for years, ever since she’d been the mare’s sitter, but she was unprepared for the sight which awaited her. The spacious area that she’d been brought to was an honest to goodness laboratory bedecked with all sorts of imposing and wholly unfamiliar equipment.

Looking to one side and spotting a number of dressing gowns, Shining gulped. “You…you don’t need us to change ~ do you?”

“What? No, of course not - well, unless you two wanted to change,” Twilight awkwardly laughed. “I am not going to let you two get frisky and life out some weird, kinky roleplay in my lab - nope, no way, no -”

“Twilight…” Cadance muttered as she closed her eyes and pinched the bridge of her snout.

With her mouth open and finger held up, caught mid-sentence, Twilight lowered her hand. “S…sorry about that - anyways, yeah, so help me understand how all this happened. From what Rarity was telling me, Celestia is in a comparable state to yourself.”

“Yeah…” Shining groaned, stepping forward and rubbing the back of his neck. “They kinda went overboard and ambushed me.”

“Ambushed?” Twilight repeated, askance. “What do you mean, ambushed?”

Unwilling or unable to meet her gaze, he fidgeted uncomfortably. “Ok, so…”

Cadance held back as he delicately explained what had happened. It was actually rather impressive that he was able to give as many details as he did without the provocative minutia involved with the impassioned morning in question, but he was somehow able to pull it off - at least for the most part. One small thing he neglected to mention was how she and Celestia had used a bit of magic on him alongside the potion he’d gulped down. Moments from giving the extra detail, she stopped herself and squinted over at him.

It may have been her imagination playing tricks on him, but he looked taller than usual - broader and a bit beefier as well. The polo he was wearing, one of his favorites, tightly hugged his chest, shoulders, and biceps, while the cuffs of his slacks had settled above his ankles. Whether it was a trick of the light, the result of washing his clothes in water that was too hot, that her brain was on the fritz, or some combination of the three was anypony’s guess - nevertheless, it derailed her thoughts and sent them flying in a dramatically more sensual direction.

Her attention, like many times before and many times assuredly to come, eventually settled on his groin. The imprint of his package was subtle, barely noticeable to a passerby, yet it was enough to dampen her panties in an instant. Darned if she knew what plans he had after their visit had concluded, but she was going to peel him out of his attire and remind him why he was the luckiest stallion in all of Equestria the second they got a moment’s privacy.

“Cadance?”

She’d spent more intimate time with him than she dared to consider, and his every erotic detail had been seared into her memory. His masculine scent, the slight upward bend in his rigid stallionhood, how his seed felt when it flowed down her throat or bathed her interior - everything about him was perfect. Without so much as thinking about it, she inched closer to him and reverently caressed his brawny arm.

“Cadance!”

“W…wha…” she coughed as she was torn from her stupor.

Both Shining and Twilight were staring up at her with a mixture of confusion and concern. Darn it - not again. She’d been losing track of herself with increasing frequency over the last few weeks, and she suspected things were only going to get worse as time progressed. She cleared her throat and backed away from her hot, studly hubby as she wrestled her lecherous subconscious into submission.

“Sorry, I was distracted,” she finally admitted, feeling blood rush to her face.

“Distracted - right,” Twilight whispered. Shifting her focus over to her brother, she cocked her head. “Is this a new development?”

Crossing to and leaning against a counter, Shining hung his head. “Honestly, yeah. It’s not uncommon for her to kinda get out of it when I get out of the shower or if I’m changing, but now it’s happening all the time! Just the other day, when I was on duty with the guard, she nearly tore my cuirass off and -”

“Ooooooooookay,” Cadance hastily interjected. “I don’t think she needs to hear about that…”

Having fetched a notebook from beside a microscope, Twilight sagely nodded and jotted something down. “And that’s abnormal behavior?”

“I’m pretty sure it is - honestly, you’ll have to ask her,” he grumbled. “It’s hard for me to tell if she’s sneaking around and spying on me because she’s good at it.”

Scrunching her snout, Twilight shot Cadance a look of disbelief. “Seriously, you’ve been peeping on your husband?”

“It’s not that big of a deal,” he chuckled. “Don’t be mad at her because she’s better at it than you are - besides, I -”

“Shining!” Twilight barked, her face having gone beet red.

“What?” he shot back. “I didn’t care then and I don’t care now!”

“W…well you didn’t catch me watching you change from outside your bedroom window!” Twilight countered.

Cadance’s eyes shot wide and her jaw nearly hit the floor. “Says the mare I caught doing the exact same thing a few nights when I was coming over to pick him up!”

Reeling back as if stricken, Twilight clutched a hand to her chest. “I…I don’t have the slightest idea what you’re t…talking about - anyways, I need to get changed before we move onto finding answers and forgetting this discussion ever happened. I’ll be right back,” she hastily remarked as she briskly trotted away and saw herself out.

Looking over to the door she’s exited through, Shining knit his brow. “Was that true?”

“I am not getting into it,” Cadance huffed, folding her arms beneath her heavy bosoms. “If you want to ask her about her peeping habits, that’s all you, mister my wife’s a voyeur.”

Appearing simultaneously amused and flattered, he strolled behind her and rubbed her shoulders. “Honestly, I’m not any better than you are.”

She glanced back at him and turned slightly. “Really?”

“Mm-hmm,” he softly confirmed as he nodded. “There’s just something sexy about watching you when you don’t know I’m there.”

Steadily swinging one arm back, she ran her hand over his hip. There may have been stallions in the world bigger than him, buffer than him, and younger than him, but Shining was perfect in her eyes. In spite of having been married to him for ages, more than half of her life at this point, and having known him for even longer than that, she never tired of him - if anything, his looks and suave personality had gotten better with age. Coming just shy of caressing his groin, realizing what she was doing, she stepped away and staved off the temptation of doing anything frisky.

“Looks like Twi hasn’t used this place in a while,” she noted, halfheartedly inspecting a shelf of what appeared to be dressing gowns.

Meandering over to a neatly organized rack of contraptions, Shining picked up a piece of equipment and quickly dropped it. “What the heck was she even doing down here?”

Cadance twisted around and spotted what had prompted his question. There were all sorts of machines and devices throughout the chamber, many of which were unfamiliar to her, although the one that Shining had been inspecting was unmistakable. With a quartet of hoses leading from a central body to four small suction cups, there was only one thing the apparatus could be - a milking machine.

While they had their own milking machine squirreled away in their castle, the model that Twilight had was far larger and seemed to be designed for livestock. How would her output compare to a cow’s? Would Twilight notice if it went missing? Could it actually be used on a pony? Beset by questions, each of which being more depraved than the next, she shivered when she felt a cool moistness against her breasts.

Glancing down at her rack, she grimaced. Even though she was wearing a bra and nursing pads, the wet fabric over her bosoms spoke to how prolific her breasts could be. Celestia may have her beaten in regards to the sheer size of her bust, but she was just as productive as the older, slightly larger alicorn.

“Uh - honey?” Shining mumbled.

She rubbed her temples and closed her eyes. “Yes, I know…”

Fantastic - now she was going to have to deal with whatever Twilight was going to subject her to while she was leaking milk like a broken faucet. Turning and scanning the room, hoping to find some tissues to stuff in her brassiere, her eyes shot back over the gowns she’d found moments prior. Like a bolt from the heavens, an idea struck her as she fixated on the simple garments.

Twilight had mentioned something about samples, and it wasn’t like her sister-in-law hadn’t seen her naked before, so perhaps a change of attire was due. Without saying a word, she reached behind herself, grunted, and pinched the zipper of her dress. She wasn’t sure if she was a genius or just a horny idiot - in either case, she was about to make lemonade from lemons.

“I - ummm…” Shining hummed behind her. “What are you doing?”

Without looking back, once she was finished opening the back of her gown, she lightly pulled the fabric down her shoulders. “Changing…”

She wasn’t about to lie to him, but dancing around certain details would be in her best interest. Shining was a shrewd and resourceful stallion, but he could be a bit gullible at times - something she’d occasionally use against him. It was obvious that she was changing, slowly and sensually removing one piece of clothing after the next, although she wasn’t about to admit why she was stripping.

Practically naked, save for her heels, she leaned against a nearby countertop, pulled at her shoe, and spied movement to her left. She hadn’t seen it earlier, but she’d wound up standing next to a large, wheeled mirror oriented above the stainless steel surface she was using for support. Her reflection only locked eyes with her for a second, before her attention was drawn from her face to her gratuitous curves.

She wouldn’t consider herself an arrogant mare by any means, but she was proud of how she looked. The engorged bosoms resting over her gravid belly, her ample, foal-bearing hips, the absolute dump truck of her tush - yeah, Celestia may have been slightly more curvaceous than herself, yet she looked just as stunning in her own right. Turning around and keeping her eyes on the mirror, she playfully wiggled her tush and smirked.

As she sent power into her horn and levitated one of the uniforms from the nearby rack, her marehood quivered with anticipation. Was it unwise to try and seduce Shining before Twilight returned? Yes. Had her wanton desires overpowered her sense of reason? Again, yes. Straightening up and extending her arms over her head, she hovered the gown onto herself.

The simple article, little more than a long, open-fronted shirt, clearly hadn’t been made for a mare of her size in mind, though that could work to her benefit. With the fabric falling open, exposing her chest, stomach, and bare loins, she lazily wheeled around and strutted over to her hubby. While she may only have enough time to get him riled up, she was going to make sure he’d be eager to get home and give her some personal time.

“Oh doctor,” she dramatically lamented as she pressed the back of one hand to her forehead, “you simply must help me.”

“I…wha…” he sputtered, peering up at her.

Grabbing his wrists, she lifted his arms and crammed his hands under her tits. “They’re just so big and heavy,” she moaned, closing the gap between them and sandwiching him against the exam table. “Isn’t there anything you can do?”

With a wry grin on his face, he slid his palms upward, over her bosoms, and ran his fingers over her rock-hard, practically gushing nipples. She didn’t have to look to tell he was thrilled by the spontaneous and passionate development, and she’d be willing to wager his slacks were struggling to contain his growing erection. There were any number of things she could have said or done to get him more excited than he already was, but there was one particular way that never failed to get his motor running.

Resting her hands on his shoulders, she backed away while bending forward at the waist. “Moo…”

As he stiffened in more ways than one, a smirk split her muzzle. She almost felt bad for tactically hammering at one of his top fetishes - almost, but that didn’t stop her from hitting his buttons. Though their love for one another was limitless, they could and regularly would attempt to mischievously provoke one another in lascivious ways. Sidling over just a bit, she bent forward, placed her hands on the table, and rolled her shoulders from side to side.

Hanging heavily from her chest, her gargantuan breasts wobbled and sprayed milk to the floor. She couldn’t explain it, and it certainly didn’t bother her, but Shining had a profound weakness for cow-themed lewdness. There were a number of costumes she’d gotten over the years, including a very scandalous cow-print sling bikini she liked trotting around with while wearing a bell around her neck and a pair of novelty horns on her head, and she had no shame in parading herself around their bedroom adorned in them for special occasions or when the mood struck.

Simply put, toying with one another was fun in the best of ways. Sometimes she’d be the one taking the offensive, like how she’d just thrown him for a loop - other times, he’d be the one to seize the initiative. On more than one occasion, he’d sneak a collar and leash on her while acting deliciously villainous - even going so far as to don Sombra’s old cape and crown. Watching him walk down her body and glide a hand down her back, she suppressed a moan when he smacked her generous backside.

“Don’t worry, I think I have just the thing to help you out,” he breathed.

As he kneaded her ass and gave it a second, significantly harder slap, setting a shockwave through her doughy cheek, his horn started to glow. Twilight could reappear at any second and walk in on a scene that was anything but fitting for the circumstances, but the threat of getting caught didn’t deter them - in fact, it added a deliciously naughty element to the mix. Eyeing the door and holding her breath as his fingers crept into the cleft of her tush, she gasped when two cold, unyielding metal flanges were pressed to her nipples.

While the contraption was obviously an industrial model, it was only barely able to fit her mammoth teats. The vivid, tender flesh of her areola was only covered slightly by the suctioning cups affixed to her breasts, allowing trails of milk to stream down her bosoms and to the floor below her. If or when she was able to procure one of the devices for herself, she’d have to order larger flanges or possibly get a pair made specifically for her.

She’d been right about one thing - the milking machine was far, far more forceful than the one she had at home. Clamping her eyes shut, she hissed and arched her back. This wasn’t how a mare, much less a Princess like herself, should be treated, yet the intense sensation of having the milk fiercely drawn from her tits felt incredible.

Gently patting her thigh and prompting her to spread her legs, Shining ran a thumb over her clit while kneeling down behind her. “Shhhhh,” he quietly hissed. “It’s okay, Bessy - ol’ Shining’s gonna make sure you’re nice and satisfied.”

She’d be lying if she said she didn’t enjoy pretending to be a cow, but this was the first time she’d genuinely felt like one. The contraption violently gulping down cup after cup of milk from her udder-like breasts, the cool air against her skin, the weight of her bosoms and the foal in her belly - with her eyes shut, she could practically imagine herself as some gravid bovine in some quaint little veterinarian’s office. Whimpering as Shining sank three fingers into her depths, she bucked back against his hand.

“Go on,” he faintly urged, “gimme another little moo. I know you -”

“Mooooo,” she loudly mewled, shedding her regal veneer as though it had never existed.

Continuing to finger her and expertly massage her g-spot, he kissed her upper thigh. “Atta gal…”

This was so wrong, so indecent, yet it was positively electrifying. There she was, one of the four Princesses of all Equestria while being treated like a farm animal, and she loved it - to make matters worse or better, Shining was well-aware of how aroused she was. He knew her inside and out, both in a literal and metaphorical sense, so she never stood a chance against him.

Taking his time with her, alternating between fixating on her clit and her g-spot, he pushed her to the brink of release before snatching a climax away. She adored him with every fiber of her being, but she’d be the first to admit that his particular brand of affection was a double-edged sword. While he could deliver her to the gates of ecstasy with virtually no effort, he’d typically tease her until she was begging for release.

Her fears were brought to fruition when he withdrew his hand and stood up. “C’mon, gal, ya can’t just think about yourself ~ can ya?”

Peeing over her shoulder at him, she fell motionless when she saw what he was talking about. At some point or another when he’d been getting her off, he’d opened his pants and hauled his stallionhood free. Whipping around so fast that she nearly lost her footing and fell, she drove her snout to his groin and deeply inhaled.

If she could have found a way to bottle his musk and sell it, she had no doubt that mares everywhere would be buying it to smell on long, lonely nights - fortunately for her and unfortunately for everypony else, he was a delight that only she and Celestia got to savor. Pulling back and dragging her tongue from the base of his shaft to its blunt crown, she angled his stallionhood toward her muzzle.

For the second time since they’d arrived at the Castle of Friendship, she found herself a bit perplexed. Shining’s stallionhood had always been impressive in both length and girth, yet now it appeared even more imposing. While she could attribute a bit of her confusion to him being particularly aroused, or perhaps that she was more than a little worked up herself, she couldn’t shake the thought that his tool was slightly bigger than it was supposed to be.

Adjusting her positioning ever so slightly, she sandwiched Shining’s shaft between her tits while putting her body to work. Being tall and with an exceptionally large rack came with a few drawbacks, such as fitting through small door frames or into passenger train cars, but the benefits far outweighed the costs. She bobbed her head while rocking forward and back, simultaneously using her snout and breasts to get him off.

His eyes fluttered and he released a contented sigh that fueled the fires of her determination and lust. Pleasuring him was its own reward, as or at times even more gratifying than the physical bliss of being plowed by him, and it spurred him on like few things could. Groaning around him and lavishing his sensitive cock-head with her tongue, she gradually increased her pace.

While she wouldn’t have minded getting a hot, rich load of his cream as a mid-morning snack, her desires grew more ravenous as the seconds dragged on. Contending with the idea of getting screwed in Twilight’s lab, tempting fate and what would assuredly be an awkward moment if they were caught, was titillating to a fault, but the milking machine - sweet, merciful Celestia, the milking machine was driving her insane.

Regardless of whether the contraption would be able to drain her fat, milky tits dry before they were finished fooling around, the rhythmic, almost violent suction on her nipples was amazing. Fighting the urge to lower a hand to rub her aching marehood, she held out for as long as she could. If she was going to cum, a prospect that grew increasingly appealing by the second, there was only one way she was going to do it.

While she rubbed her breasts to increase the flow of milk, it grew harder and harder to concentrate. This wasn’t supposed to be happening, she hadn’t come to Twilight’s castle to have a risky tryst with her husband, yet she’d succumbed to her sinful yearnings. Willing herself not to stop, if only to test her mettle, she peeked up when he ran his fingers through her mane.

“I love you…” he whispered.

He’d told her that more times than she could count, yet the confession shattered her composure with ruinous force. Practically bolting to her feet and detaching from his stallionhood with a soft pop, she eased herself onto the table behind her, rolled back, and lewdly splayed her legs. Subtlety be darned - it was neither the time nor the place to get her brains screwed out, but he could not tell her he loved her while she was blowing him without expecting to deep-dick her into a coma.

He faltered as his eyes shot to her sopping wet, winking marehood. “Right n…now?”

Calling upon her arcane fury, she levitated him from the floor and hurled him at herself. Teetering on the brink of a rut-lust or not, she was not to be trifled with. In the blink of an eye, he flew at her, sheathed his stallionhood in her balmy depths, and fell over her titanic belly. Though she wasn’t even close to being fully to term, her stomach was so large that he struggled to fully hug it with both arms. Buck it - should Twilight end up busting them, she could always blame her wanton actions on her pregnancy.

She sweetly smiled as she lifted his face and gazed into his wide, shocked eyes. “Start moving or I’ll start moving you…”

Nervously or excitedly nodding - honestly, it could have been either or both, he gave her what she wanted. Like a spring-loaded trap, just as the tip of his shaft kissed her womb, her legs snapped shut around the small of his back. He was stuck, like it or not, and there was only one way he was going to get free.

“As - huff - tight as ever,” he snorted.

She’d been thinking the same thing herself, albeit in a different light. Though she wasn’t making any active effort to constrict his length, her marehood was clamped around him. It wasn’t possible that his endowment had gotten even larger than usual ~ was it? Making a mental note to break out the measuring tape after she got home, she experimentally contracted her pelvic muscles.

Peppering her gigantic stomach with kisses, he braced his legs and started thrusting. The logical part of her brain told her that nothing had changed about him or his sensual skills, that his bucking hips and thick, wondrous stallionhood was the same as it had ever been, yet it sent bolts of rapture surging through her frame as though it was the first time he’d claimed her. Constricting her legs in tune with his plunges, she lent him a sliver of her strength while he picked up speed.

“Just gotta,” he grumbled, reaching for the metal cylinders affixed to her right breast.

Looking down at him, she quirked a brow. “What are you - Aaaaaghn!”

Her sinful wail rang in her ears as he threw the still-sucking component away and latched onto her freed tit. The contrast of cold metal against his warm, pouting lips was like night and day. With her pleasure mounting and sending her spiraling to a climax, she clutched the back of his head and pulled his face into her bosom.

She was definitely going to have to figure out where Twilight got the heavy-duty milking machine - plus it couldn’t hurt to pop by the Carousel Boutique to see if Rarity had any cow-print material on hand. A tremor crept into her thighs, her heart was going a mile a minute, and the breath hitched in her throat as she teetered on the brink. She was close - very, very close to cumming; all she needed was a little push.

“If - Nnnph,” Shining grunted, screwing his eyes shut in concentration. “If you give me another moo, I’ll -”

“Moooo!” she howled, knowing good and gosh darn well that he was going to say something about giving her a cream pie. “Mooo - you magnificent stud!”

Her outburst did the trick, setting him into a frenzy, but it worked a bit too well. The force of his plunges increased, he growled around her nipple, and a faint light radiated from his horn. She was sure he was up to something, calling upon his magic for some inexplicable reason, although she was unprepared when she felt the unmistakable tingle of sorcery on her clit.

She came in an instant, braying out in ecstasy while a torrent of marish juices flowed from her stuffed, battered marehood. The climax was a particularly intense one, in part due to the multi-pronged assault she was weathering, and it was punctuated by aftershocks of bliss. There were times when she’d mused on what it was like to be a stallion, but moments like these, having one orgasm rebound and lead into another within seconds, made her immeasurably thankful that she was a mare.

Shining gave her no quarter, angling each thrust to hit every sweet spot in her depths while he used his muzzle, magic, and hands to deliver unimaginable pleasure to her. In the face of such rapture, irrespective of her stature and incalculable arcane might, she was completely and totally helpless - not that either of them minded in the slightest. Keeping her eyes on his face, she coaxed him off her breast and lifted his chin.

Craning his neck and pursing his lips as she leaned in, they kissed deeply and passionately. Their tongues entwined, their breath mingled, and they moaned into one another’s snouts. There were a great many things she was grateful for, from being an alicorn to having two wonderful children, yet every good thing in her life was due to or made all the sweeter by her beloved husband.

By the time she felt him starting to flare, she’d endured another three climaxes. She hadn’t the faintest idea of how long he managed to last, yet the sensation of his stallionhood pulsing and swelling drove her into a frenzy. All but driving her tongue down his throat, and keeping a vice-grip on him with her legs, she held him to herself when he reached his limit.

The nearly scalding heat of his seed flooding into her was phenomenal. Envisioning him knocking her up again, fantasizing about his rich-foal batter claiming her womb to sire an heir, or even better another, she was granted a final climax along with him. As he pulled back, met her eyes, and grinned the same silly grin he’d given her on prom night so many moons ago, she exhaustedly smirked.

Even without the enhancements of potions or enchantments, his output was awe-inspiringly prolific. Each throb of his stallionhood sent a small tsunami of his essence into her, coating every nook and cranny of her depths, and it went on seemingly without end. Though she already appeared heavily pregnant, her belly distended and swelled from the absurd influx of spunk combined with her growing, unborn foal. Maybe if she was lucky and Twilight gave her good news, foals.

She’d never considered herself overly perverse, but she loved how productive he was. No matter if she was gulping it down, getting her face covered in it, or having it flooding into her in one way or another, his cream was a gift to be cherished. Stroking her belly and feeling it swell over her sides and pushing him away from her muzzle, she opened her eyes and peered down at him.

“You - heh,” he half-chuckled, half-wheezed. “You think Twilight would notice if we borrowed -”

“Nnnf…”

Both Cadance and Shining’s heads turned to the side, drawn by the soft sound, and they froze. Lingering just within the room, lightly tweaking a nipple with one hand while the other had disappeared down the front of her skirt, Twilight fell motionless. Everypony held their breath, nopony moved, and the only noise in the lab came from the continual hum of the machine milking Cadance’s one tit and the stream of her unattended one dripping down her body and running off the exam table and pooling underneath them.

“So - uh,” Cadance began, magically turning off contraption. “Did you get this from Barnyard Bargains or…?”

“H…haymakers,” Twilight croaked as she fought with the front of her undersized lab coat. “Come on - stupid…Ugh…”

Quickly waving Shining away, Cadance forced a smile. “To be fair, it’s not like you didn’t just get an eyeful for yourself…”

Twilight pouted and ultimately held the front of her coat closed over her bust. “Yeah, but - darn it!”

The fabric slipped, the coat fell open, and Twilight’s tits lay fully exposed. Cadance wasn’t bothered by the sight in the slightest, having seen plenty of racks in her day, although the effect on Shining was profound to say the least. His blush would have been telling in and of itself, but the sensation of his stallionhood suddenly throbbing inside her was highly incriminating of his thoughts for his not-so-little little sister.

There was no way in Tartarus Cadance wasn’t going to do a bit of digging after this, carefully but tactically speaking to Shining and Twilight about their feelings about one another, but that would have to wait - for the time being, she had to tactfully deal with a literally and figuratively sticky situation. Seeing Twilight look down to the overflowing container of milk attached to the machine, she set her jaw and concentrated. With sparks and flickers of light sputtering from her horn, the vessel shakily drifted into the air.

“I’m guessing this is one of the samples you were wanting?” she inquired.

Twilight caught the ewer in both hands, nodded, and licked her lips. “Uh…uh-huh…”

Biting back a giggle, Cadance shook her head. “You can try it and I’ve got plenty more yet. Considering your brother and nieces have - oh…”

Twilight lifted the container before she could finish speaking and took a long, deep draught - several in fact. With milk dripping down her chin and onto her cleavage, she bashfully wiped her face. It wasn’t until she shifted her focus over to Shining that she flinched. He bit his lower lip, spontaneously bucked his hips, and the way he gave a low, sonorous hum that, in combination, brought her back to her flustered and clearly aroused state.

“W…w…well, I’ve gotta - um - go do science stuff,” she incoherently babbled, backing away and hitching a thumb to the nearest exit. “I’ll - uh - I’ll be back in maybe ten - no, fifteen minutes.”

With her floundering excuse given, she turned tail and ran - ran away and out of sight. Cadance would freely admit that she didn’t know everything, but she’d like to think she knew Twilight well enough to know when a mare was about to furiously rub one out. As she pondered on if the young mare had a toy in the likeness of her brother’s endowment, Shining thrust into her and tore her from her thoughts.

“One more?” he purred, waggling his eyebrows.

Snaking her legs up and hooking them over his shoulders, she clenched around his turgid shaft. To heck with it - they’d already gone this far and been caught in the act, so going a second round wasn’t going to hurt a darn thing. While he bent over and picked up where he’d left off, her hands glided up his arms. The last few weeks had been incredibly interesting, but her gut told her that things were only going to get crazier from here on out…

Chapter 2.5

Celestia opened her eyes and grumbled, cursing the many lifetimes’ worth of routine that had been hard-baked into her conscious and subconscious mind. Glancing at the bed and the two figures slumbering beside her, she turned her attention to the window of the room and the dark, cloudless night sky beyond. There was nothing forcing her to raise the sun, given that Twilight had assured her that she’d be more than happy to handle it, but old habits died hard.

Without any effort whatsoever, she shunted power into her horn and caused the first rays of light to come peeking over the horizon. Getting up early didn’t bother her all that much, nor was the trivial exertion of magical energy a bother, although she did have other issues to contend with. As she momentarily debated laying back down to get a few more minutes of sleep, an ominous rumbling crept to her ears.

Her eyes instantly shot to the side and settled on what remained of her midnight snack. It wasn’t uncommon for ponies to wake up in the dead of night feeling peckish, but her ravenous appetite, paired with the foals growing within her, wouldn’t be satisfied with something as insignificant as a few cookies or a handful of chips. Swinging her legs from the bed, she pushed herself up with a grunt and stood.

As her mouth watered and sent a bead of drool creeping past her lips and down to her chin, her hunger grew. In a fit of pique, not too long after she’d finished dinner the evening prior, she’d paid a visit to a local bakery for a desert. Her trips to the pastry shop had become increasingly frequent as of late, although she felt a bit bad about her last visit to the place. Instead of ordering a pie, a selection of bite-sized confections, or a tiramisu, she’d ordered a cake - specifically a full-sized wedding cake meant to feed a party of several dozen.

She crossed to the partially devoured towering construct, sorcerously carved a chunk large enough to sate a small family, and licked her chops. Had she been in a different setting or in front of guests, she would have helped herself to a much more modest slice - however, excluding Shining and Cadance, both of whom were soundly asleep, she wasn’t among guests. Grabbing and breaking off a sizable portion of the pastry with her bare hand, she opened her maw and extended her tongue.

She couldn’t care less how unrefined it was to quite literally cram a fistful of cake into her muzzle, but the taste more than made up for her unbecoming behavior. With crumbs and dollops of frosting falling from her hand, she peered downward, slowly chewed, and swallowed her Princess-sized bite. While she wasn’t one to make excuses, there was a darn good reason why she was ingloriously wolfing down pastry - several in fact.

Her bosoms had gotten large by any metric throughout her first pregnancy, yet they’d grown to a size that she could only describe as utterly absurd over the last three months. Being roughly the size of two small wrecking balls, her behemoth breasts had gotten so large that the view of the floor and anything directly beneath her was utterly blocked from her sight - to make matters worse, her belly, now distended to the point where it nearly graced the floor when she stood, no longer acted as a comfy shelf for her rack.

Many mares would have complained about being pregnant, bemoaning the added weight, sore feet, wild cravings, or some combination of the three - luckily for her, either due to serendipity or her predilection for motherhood, she was immune to most onerous elements of being insanely gravid. Other than her appetite spiking beyond what she previously could even consider possible and slow burn of her loins wanting to be ravished at all times, she couldn’t complain much. Snatching up another handful of cake with one hand, she ponderously turned, scratched her bare tush, and lumbered to the bathroom.

While her tits swayed and jostled from side to side, pouring pints worth of milk over her stomach, down her trunk-like legs, and to the floor beneath her, her attention drifted over to the vanity she passed. She didn’t like to brag, and she certainly wouldn’t do so in front of anypony other than her duo of lovers, but she looked good - darn good, if she did say so herself. The soft, yielding flesh of her thighs, upper arms, and monumental ass paired wondrously with her expansive chest and belly. Though she was the Princess of the Sun, she could easily pass for a Goddess of Motherhood.

Cramming yet another massive chunk of cake into her maw, she turned her back to her reflection, reached one hand back, and caressed her tush as the corners of her frosting-streaked lips turned up. “Still got it…”

There was nothing wrong with being proud of one’s looks - of course, she wasn’t the only pony who appreciated how stunning she’d become. Between Shining’s routine advances and Cadance’s flattery, she’d never felt better about herself - that plus catching guards, townsponies, and random visitors to the Crystal Castle eyeing her was thrilling. Just the other day, she’d caught a platoon Shiny had been instructing trying desperately to focus on him despite her ponderously walking in front of their formation. She grinned at the thought of that full platoon flushing crimson and all at full salute - that was until an angry guuuuurgle from her belly shook her from her thoughts.

She sighed and rubbed her tum, feeling an aching emptiness deep in her gut. Shiny and Cadence typically wouldn’t wake for another hour, so it was on her to go get something to tide herself over. Her gaze turned back to the cake on the nightstand and she sighed; if her foals were demanding she fill herself, then she would for their sake. Already she felt saliva fill her mouth just looking at the confection.

“Well buck it.” she whispered, grabbing the entire remaining cake in her magic and floating it over to herself.

It was only when it was moved next her did she catch a glance in the mirror and smirk. Had it been six months ago, she could have fit inside a cake this size herself and jumped out, nipple tassels included. Now? She grinned and gripped the massive confection in her magic, pulling it into a cylinder and watching it grow and grow in height as she shaped it thinner and thinner. Celestia stopped when it was about fifty feet long and about as wide as her fist, feeling her stomach rumble and churn in anticipation of the impending treat. She paused for a moment, turning to look back at the bed, Shiny asleep and spooning Cadence, whose womb spilled off the edge and onto the floor, rising higher than the two of them.

Cadance’s budding maternity rivaled her own. With a big, foal-filled belly and tits large enough to make coming and going through doorways a trial, she snoozed alongside her husband - not like you could easily tell though. Just a single one of her tits was expansive enough to almost entirely smother Shining and leave only his lower legs and a tuft of his azure mane peeking out from beneath the great, pillowy mound of flesh. Turning back to her creation and quietly giggling to herself, Celestia had a spark of inspiration.

Concentrating her magic, she molded the cylinder of pastry into a rough approximation of Shiny’s dick. Taking extra care to add a flare to the end, a fat medial ring and some generous, head-sized testicles, she turned back to the mirror and lovingly opened her mouth. As she slowly and gently pushed her creation forward, the now delightfully phallic cake slid to the back of her throat. Sadly, the naughty dessert wasn’t as warm or as rigid as the real thing, but she made due as she pushed it deeper and deeper down her maw.

Even more intoxicating than the feeling of being filled and stretched was her reflection. Her throat bulged around Shiny’s behemoth tool as she forced him deeper and deeper down her gullet. She forced herself to relax as the confection forced its way into her stomach proper, being constricted slightly and threatening to back up in the opening as she slid more and more into herself. Finally she felt it drop into her stomach itself and picked up the pace, the approximate marital aid moving down her maw and inside her at a brisk pace. Seemingly in a trance watching her creation disappear into herself at frightening speed, Celestia was surprised when the cakey nuts booped against her snout.

She paused to try and savor the moment, but her concentration slipped for just a moment. The shaft disappearing in her throat broke at the base and continued its slide into her guts as she found herself staring at a set of testicles that if were real, she’d desperately want her stud to have. The idea of something so heavy and full could exist lit a fire deep within her loins, a need that she’d probably have to take care of here soon. Moaning into the cakey nuts she yawned her mouth wide and did her best to take them, feeling them spill out past her cheeks and then break, landing on her bosom.

Someday she’d have to ensorcell Shiny to see just how much dick she could take, but until then, she’d gladly make due with what his admittedly exceedingly generous stallionhood offered. Scooping up the dropped cake off herself, she crammed it into her mouth and brought up one of her breasts to her mouth with her magic to wash down her binge. Her belly still hungered, but not as urgently despite the literal hundreds of pounds of confection crammed inside. Basically blind due to the size of her massive boob and straining to fit her head-size nipple in her maw, she greedily gulped down gallons of her own cream. Continuing into the bathroom, she called upon her magic to set the water in the shower running.

Their bathroom had, for the second time in the last two decades, undergone a transformation of its own. Hosting a trio of sinks, a commode that could accommodate the weight of a full-grown dragon, and a disused scale, the lavatory had been remodeled to comfortably house herself, Cadance, and their little stud muffin of a Prince - still, the crown jewel of the washroom had to be the shower. Big enough to accommodate two teams of buckball players, and tiled on four sides with the fourth being a massive sliding glass door, the shower was incredible. The floor was level with the door for about a third the length, and then descended into a deep well studded with yet more jets, allowing the princesses to comfortably bathe even at their suspected massive sizes yet to come.

Stepping in and beneath the multiple nozzles spraying hot water to the tile under her, she closed her eyes and contentedly sighed. There was a good reason why ponies said the simpler things in life were often the best. Something as innocuous as washing one’s self up was a pleasant and refreshing way to start the day - at least she thought so.

She shuffled over and extended a hand to blindly feel for the shelf holding the soap, shampoo, and conditioner. Shining and Cadance hadn’t needed to go the extra mile for her, seeing as how Cadance was slightly smaller than herself, yet they’d done so without the slightest bit of hesitation. After grabbing what she hoped was the right bottle, she lifted her head and turned it to the nearest stream of water to dampen her mane.

Not that it particularly mattered, but it was a good thing that the tile underfoot was white. Between the amounts of foal-batter Shining had spilled and the nigh-perpetual gush of milk she Cadance produced, any of the cleaning staff would have had a clear indication of just how dirty the shower could really get. As she ran her hands down her neck and over shoulders, lathering herself as she went, she suppressed a chuckle when her digits glided over her areola.

She looked good, she felt good, and there wasn’t a darn thing wrong with enjoying herself before anypony else got up, so she did just that. Straining forward and grabbing one nipple in each hand, she stroked the twin buds of flesh and sent jets of milk spraying over the wall. It was a good thing that Cadance had procured that industrial milking machine, even if she was coy about how she’d stumbled on it, because she could easily outmatch a dairy cow’s output at this point, if not most of the farm.

Keeping one hand on her left tit to knead and coax more milk from herself, she reached down her side. Getting herself off wasn’t as easy as it used to be, what with just how cumbersome her body had become, although that didn’t stop her from rubbing one out the old fashioned way - sure, she could use her magic for a bit of relief, but that simply wasn’t the same as feeling her engorged clit against her fingertips.

A soft, throaty moan crept past her lips as she caressed the plump mound of her winking marehood. Even without the water cascading over her, she was wet enough to let her have a bit of fun. Shuffling back and bracing her hand against the wall, she bent forward and allowed her belly and tits to hang heavily toward the floor, each breath causing her stomach to gently press against the floor. Only the fact that her gut extended forward and down the stairs to the well gave her the room she needed,leaning forward like this easily wouldn’t have been possible on flat ground.

Though she couldn’t see herself, she could easily picture how she must have looked. Leaned over, panting heavily and fingering herself while milk spilled from her breasts - honestly, it must have been quite the sight. The tit she was holding was so ample and soft that she genuinely struggled to hold it up as she twisted her nipple, but the lewd spectacle she was making only heightened her arousal.

As she awkwardly tried to cram a trio of digits into her winking pussy, only barely able to reach her entrance, she yelped and nearly fell when something smacked her backside. There were only two ponies who’d be brazen enough to interrupt her in such a way, and had every intention of finding out which of her lovers had decided to join her. She peeked over her shoulder with a wry grin, fully intent on provoking either Shining or Cadance into helping her out, yet she faltered when she noticed who was behind her.

Shamelessly rubbing her ass, Shining chuckled to himself. His naked body, covered in glistening streams of water, was the sort of thing fillies would fantasize about at night or in class, but his adonic good looks and smug expression weren’t all he had going for him. Drooping to the floor and swelling with every beat of his heart, his stallionhood visibly throbbed in the steamy air.

He shuffled to the side, tore his gaze off her juicy flanks, and peered up to her face. “Mind if I join you?”

Barely registering what he’d said, Celestia stared longingly at his cock. How - how was he so well endowed? Cadance had mentioned how his package seemed bigger than usual, but she’d brushed it off as the rambling of a lust-addled mare - now, as her eyes ran up and down the imposing, vascular length, she realized there may have been something to her fellow Princess’ claim. Dangling down well past his knee, thicker and nearly longer than his arm, his shaft was unable to stand under its own weight. Instead the menacing length continued to fatten and lengthen, lazily attempting to seemingly reach out towards her ass.

There was only one reasonable thing a mare in her position could do, and she had no reservations of doing it. Instead of saying a thing, she straightened up and sashayed down to the bottom of the well, hefting her breasts up to rest on the ledge and pushed into the reinforced plate glass of one wall. Though it was tempting to give herself a closer look at his inexplicably large stallionhood, there was another, far more enthralling way for her to access his endowment.

One of the only regrettable things about her girth was that going something as easy as kneeling and giving Shining a blowjob was a herculean endeavor. Her belly and breasts, though alluring, made it all but impossible to bury her face in his goods without her laying down or levitating him up to her chest - bearing that in mind, she did the next best thing. Smooshing her tits against the glass, she threw her arms back and grasped the yielding cheeks of her ass.

Any even remotely straight stallion would have pounced on her the moment she’d presented herself in such a slatternly way, but Shining was no amateur. Kicking a stool over as she spread and braced her legs, he smiled all the broader. The cake she’d snacked on was nice, some of the best available outside of Canterlot, although having a bit of cream would be the perfect complement to the pastry.

Though she could only see his head and shoulders as he stepped up behind her, she knew good and well what he was planning to do. He was a little under half her height, with the top of his head barely reaching her massive, swollen suns adorning her wide, callipygian flanks. Still the vast size difference between them didn't deter him - in fact, he liked having her tower over him. After learning the first time that her body grew to accommodate her unborn foal or foals, making her taller and broader than she was when she didn’t have a bun in her oven, he’d adapted well to satisfying her in all her titanic glory.If anything,

She knew she was acting needy, displaying her gushing, winking marehood like some desperately horny thing, but she didn’t care - moreover, neither did he. Clutching the base of his shaft, he touched the tip of his stallionhood to her entrance. It was painfully obvious what they wanted, regardless of whether his erection was purely from arousal or simply morning wood, and there wasn’t a force in Equestria that was going to stop them.

Throwing his arms wide and hugging her tush, he bucked his hips and steadily drove his stallionhood into her balmy depths. Her eyes went wide, she stifled a whimper, and she fought the urge to buck back against him. Cadance had to have been right about him; flying in the face of all reason, his dick felt significantly thicker than it had any right to. If anything her estimation of his girth earlier seemed to be about half of what was currently spreading her wide.

Waiting until his medial ring kissed her sex, she threw her weight back and hilted herself on him. Despite his comparably small stature, he filled her entirely - and she did mean entirely. His cock-head ground against her cervix, she’d only barely been able to sheath the entirety of his length, and his weighty, pendulous balls came to rest against her bulging clit. If his dick hadn’t grown, maybe she was getting delirious - in any case, after giving her a few seconds to adjust to the monumental intrusion, he started to move.

She hung her head and watched as milk practically erupted from her tits. Sandwiched between herself and the glass partition, her breasts were squeezed every time he thrust into her, running down her body and the walls to pool at their feet. With rivers of cream mingling with the water around them, she got his timing down and began bucking back against him. Other mares may have just stood there and taken what he had to offer, content to let him do all the work, but she was better than that.

Clenching on his backstrokes and relaxing on his plunges, she lovingly milked his shaft - an act that was swiftly rewarded. The sound of magic split the air as a warm, tingling sensation surrounded her nipples and clit. She didn’t have to look to tell that he was going to make sure she didn’t leave the shower without being completely satisfied.

Had there been a camera present, the spectacle wouldn’t have looked out of place for an adult film. The enormity of his cock, the disparity of their sizes, and how she grew louder and louder with every passing moment was wondrously sinful, and it didn’t take long for his efforts to bear fruit. Skyrocketing towards relief after what couldn’t have been more than a few minutes, she tensed.

The water and dairy beneath her were joined by gouts of climactic juices surging from around Shining’s pistoning shaft, and despite being built for a literal flood the shower drain just could not keep up with their lovemaking. Thick pre and milk both surged the water levels higher, lapping against their ankles and then calves. It was a toss-up on if he’d slow down after making her climax, but he didn’t relent - if anything, her orgasm fanned the flames of his stallionly desires. Tightly gripping her ass, unable to fully reach her hips, he hammered away at her from behind.

Her initial climax was followed up by a second, then a third and a fourth, until she was essentially cumming nonstop. With her knees shaking and threatening to buckle, she put her full weight against the glass and howled out in glee as her tits cascaded great waterfalls worth of milk. Darned if she could say that there were other studs in the world who could rival Shining, but she liked to think he was one of a kind.

On and on he went, fucking her while using his sorcery to tease her most sensitive bits, until his rhythm gradually changed. The long, exquisitely deep strokes he favored shifted to rapid-fire, almost frantic thrusting. Though she couldn’t stop herself from braying and drooling into her cleavage, only adding to the mess she was making, she could feel him starting to flare.

“B…buck,” he wheezed, plastering himself to her upturned tush. “Don’t t…think I can…”

It was cute that, in spite of how much he did for her, he thought he had to hold himself back at her expense. Summoning her strength and wading through her blissful haze, she arched her back and tightly squeezed his cock while ramming him as deep as she possibly could. Her ass clapped shut around his torso and thighs as the added bit of stimulation did the trick, sending him over the edge and sealing his fate.

Slamming his hips to her rear, he groaned as he came. She could barely hold herself up throughout his climax, enduring a final orgasm while his seed flowed into her. Her belly gurgled and sagged to the floor under the weight of his load. His orgasm was like a river gushing into her, her belly rounding off and pushing both of them both backwards and up one stair, and then another as she came yet again. Irrespective of if his cock increased in size, the incredible volume of his essence was more than enough to knock up a mare several dozen times over.

“H…holy heck,” she rasped, feeling his seed gushing out from around his wildly throbbing length.

She’d definitely need to investigate what was going on with him, but that could wait until after she washed up, recovered, and ate a hearty breakfast.She hoped that he might stay there for a while, locked together in bliss, but eventually his orgasm petered out and he gently patted her ass. Shivering as he withdrew, she held herself steady and slowly turned to try to face him, her horn alighting as she sealed up her well-loved snatch to hopefully make the most of his generous deposit.

Rocking backwards she heaved herself up to her hooves, her belly having roughly doubled in size for the moment. It was likely just temporary, but her womb bulged another half her height below her hooves to rest on the bottom of the well and rounded out in a perfect, stretched sphere neatly attached to her torso. They both glanced over to the shampoo, grabbed the bottle with their magic, and snickered. No matter what was or wasn’t going on with him, she’d never been more thankful that he and his wife were happy to have her as a third…

Chapter 3

Peering out over the packed stadium, Cadance smiled broadly. While she hadn’t needed to attend the graduation ceremony for the newest batch of Royal Guard recruits, she saw no reason not to - especially because she was alongside her lovers and one of their most cherished friends. She turned her head to her left and right, peeking over at Celestia and Shining respectively, before glancing over her.

“What?” Rarity softly inquired.

“Nothing,” Cadance hummed, “I’m just glad that you decided to join us.”

Reaching out and caressing her shoulder, Rarity grinned. “Why would I not? It’s not every day that I get to pay a visit to the Crystal Empire and enjoy such regal company.”

Celestia dismissively waved a hand and shifted in her seat - a seat which creaked in protest beneath her. “As if Twilight doesn’t count.”

“Darling, you know as well as I do that I don’t see her like that - granted, she’s as much of a Princess as either of you, but you two held your crowns long before she did. Twilight was a friend before she became royalty, unlike yourselves,” Rarity giggled, reaching out and rubbing the alicorns’ shoulders.

Giving a deep, contented sigh, Cadance closed her eyes and shook her head. Other than being a fantastic friend, Rarity was an invaluable asset - doubly so as of late. Now more than half-way through their pregnancies, Celestia and herself would have been in dire straits without the couture’s expertise. While an outside observer may have just seen a pair of well-dressed Princesses sitting and enjoying the ceremonies alongside Prince Shining Armor, the reality was a bit more complicated.

Through a masterful combination of spellwork and enchanted materials, Rarity had done the unthinkable - she’d crafted garments that not only allowed her to function, being able to out and about like any normal mare, but she appeared to be a fraction of her actual size. The truth of the matter, despite her look in public, was that she’d grown by an order of magnitude. Her bust, belly, and backside were all much, much larger than they’d been when she’d been carrying Flurry or Aegis - so much so that, without the use of her ensorceled garments and magic, she’d be practically immobile.

She turned her head and looked back at their esteemed guest as her thoughts wandered. Rarity wasn’t pregnant, nor had she expressed any interest in having a foal herself, yet her time with her and Celestia had taken a toll on her. It had come as a pleasant surprise to find out that the seamstress had more than simply an appreciation of full-figured, expectant mares, and she’d been more than happy to indulge her. Regular fittings and routine refinement of the charms on her wardrobe meant she was seeing the skillful unicorn more often than ever.

“Care for some refreshments, Rarity?” she purred, running one hand over her bosom.

Rarity straightened in her seat and instantly looked away. “I’m q…quite alright, dear!”

Relenting if only for the time being, Cadance bit back a chuckle. It was hard for her to tell if Celestia had been telling the truth, claiming that Rarity had accosted her and fervently nursed on her nearly two months ago, but what actually had happened was of little consequence. At the end of the day, regardless of what may or may not have transpired within the Carousel Boutique, she had a quite eager volunteer to help drain milk from her prodigious breasts.

“You mares play nice,” Shining noted, casting a knowing glance between the trio of mares.

“No promises,” Celestia countered as she shamelessly leaned across Cadance’s lap to stroke his inner thigh.

It wasn’t the fact that Celestia was brazenly pawing at her husband that annoyed her - it was that she hadn’t struck first. Her ravenous appetite, expansive figure, and the need to wear spellbound clothing to do much of anything could all be annoying at times, but her hormones - heavens be, her hormones were like a rollercoaster! Pushing her fellow Princess away, if only out of a bit of spite, she folded her arms over her chest and pouted.

“Come on,” he sighed. “Don’t make me sit between you three…”

“As if you wouldn’t enjoy that,” Celestia giggled.

Cadance went to reply, to defend Shining’s honor, but she remained quiet. She knew better than anypony that having a healthy, virile stud sandwiched between herself and Celestia would be disastrous. It was hard enough for her to control herself around him, so adding a competitive element to the mix, on some subconscious level vying for his affection, magnified her already heightened libido.

“Well it certainly wouldn’t bother me at all,” Rarity chimed in, drawing the trio’s attention. “I’m not sure how much I’d be permitted to help with, but spectating would -”

“Not helping, Rarity,” Cadance grumbled.

Extending her arm to one side, barely aware of what she was doing, she rubbed Shining’s upper leg to assert herself. She loved Celestia as both a mentor and a partner, although she was his wife - yes, they’d discussed a wedding that would include all three of them at some point, but she was going to wield her marital status for as long as she was able. As her fingers graced the imprint of his stallionhood, a thrilled shiver shot through her.

Nopony could explain it, not even Twilight with her extensive knowledge of the arcane, but something was going on with Shining. The white in his mane and beard had all but disappeared, he’d inexplicably grown nearly a foot in height, and his stallionhood - mother of mercy, his stallionhood was more impressive than it had ever been! She’d initially thought she was losing her marbles, that it would be impossible for her hubby’s endowment to have gotten substantially larger, yet the repeated measurements she’d taken didn’t lie - his cock had become monstrous.

Pushing himself up and gently pushing her hand away, likely knowing what direction things were taking, Shining straightened his uniform. “I’m going to use the little colt’s room. Do any of you fine mares want anything ~ a drink or snack maybe?”

“I’m quite fine, but I do appreciate the offer,” Rarity replied.

Celestia shook her head. “Nothing for me.”

“Same,” Cadance noted.

After the incredible rutting that morning, followed by the banquet she’d had for breakfast, there wasn’t much she wanted - of course, that would change in a few hours, although that was an issue she’d tackle when the time came. Waving to him as he departed, she turned her eyes back to the field. While she couldn’t say exactly what the remainder of their day would entail, after the graduation was finished, was certain that it would end the way most others did.

Nearly every night before going to bed, Shining would tend to her marish needs. Some evenings, she’d get rutted into a stupor, cumming so hard and so frequently that she was unable to stand - others, she’d play with herself while assisting him and Celestia. Regardless of how things played out in their bedchamber, she always - always drifted off gratified in every conceivable way.

As she turned her nose up and sniffed the air, the corners of Celestia’s lips turned up. “Somepony’s excited.”

“Says the mare who’s probably drenched her panties at this point,” Cadance huffed.

Celestia leaned in and brought her muzzle to Cadance’s ear. “You know, being up here and away from the crowd, nopony would notice if things got a bit steamy.”

Merely hearing the sinful proposal was enough to make Cadance’s marehood seize upon itself. They were in a private box situated high above the grounds, and the chances of anypony seeing what they were doing were slim, but they couldn’t just spontaneously help themselves to some hanky-panky in a colosseum ~ could they? Reining in the slavering, uncontrollable beast that was her lust, she drew a deep breath through her nose, slowly exhaled through her mouth, and centered herself.

“I…I wouldn’t mind - I m…mean, don’t hold yourselves back on my account,” Rarity stammered.

Shifting in her chair, Cadance leered back at Rarity. She wouldn’t be shocked if her friend eventually became involved with their amorous affairs, with the way things had been going lately, but this was neither the time nor place for such things. As quickly as it had appeared, her irritation faded.

“Rarity,” she softly began, “if you’d like to join us, you could simply ask…”

Celestia rolled her head back and drew her hands over her face. “I’ve been telling her that for at least a month…”

Put on the spot, Rarity fidgeted uncomfortably while holding a hand to her chest. “It’s hardly my fault! With as big and beauteous as you are, not to mention your status as Princess, it’s to be expected that mares like yourselves are assertive. A mere commoner, like myself, could hardly ask two alicorns and their charming Prince to participate in any of their passionate activities.”

“Uh-huh…” Cadance grunted, wholly unconvinced by the humble act. “You do remember that you’re one of the Elements of Harmony and friends with every Princess in Equestria ~ right?”

“Plus I heard she’s fooled around with Twilight,” Celestia nonchalantly added.

Rarity froze as cold beads of sweat formed on her brow. “I…I haven’t the s…slightest idea what y…you’re talking about. Twilight and I w…would never -”

“Would never get frisky during a sleepover with Applejack?” Celestia interrupted. “Do bear in mind that Twilight was writing to me on a near-daily basis after she moved to Ponyville, and some of her messages were, shall we say, a bit suspect…”

“Wait,” Cadance croaked, taken aback by the revelation. “Rarity, is that true?”

She’d long suspected that the Elements of Harmony, all six of them, may have been more than just friends, but this was the first evidence she’d ever heard to give it any real weight. There’d been times when the sextet would act a bit too close, namely between Rainbow Dash and Applejack, and she couldn’t help but think that there was something going on between them - after all, as far as she knew, none of them were in relationships. Waiting patiently for a reply, she watched as Rarity began to squirm.

“W…well,” Rarity gulped, rubbing the back of her neck while her face went beet red, “I’d hardly say there was a…anything particularly frisky about…”

As much as Cadance would have relished the impromptu inquisition, she knew when to hit the breaks. Teasing a friend was all well and good, but there was a fine line between having fun and making somepony genuinely uncomfortable. Extending an arm and patting the flustered unicorn’s knee, she smiled.

“How about this,” she murmured, “if you ever find the courage to talk to Celestia, Shining, and myself about a sleepover at our castle, I love to hear about…”

She fell silent and started when an odd sensation struck her - specifically her unmentionables. It wasn’t a secret that she’d gotten a bit worked up, with her nipples being hard enough to be seen through her top and her bouquet strong enough to be detected by Celestia, although that wouldn’t explain what had just happened. Twisting in place, she peaked a brow down at her groin.

“Is something the matter?” Rarity asked.

Cadance slowly shook her head, genuinely unsure. “I’m…I’m fine…”

It was over as quickly as it had started, although she could have sworn she felt something brush against her marehood. Considering that there was nothing in her chair, and that there wasn’t anypony around to slip anything up her dress, she must have been imagining things. Shaken from her thoughts by the sound of applause, she turned her attention back to the throng and the rows of impending graduates.

Following her gaze, Celestia nodded to an armored figure waxing poetic about the duty of the Royal Guard. “I’m a bit surprised that Flash Magnus is so long-winded…”

“Well I certainly am not,” Rarity tutted. “When he came to speak at the School of Friendship, he went on and on for ages! If Twilight hadn’t intervened and politely told him to wrap things up…”

Cadance barely paid the banter any mind - not because she wasn’t interested, but because shortly after Rarity started talking, she felt it again - something softly nudging her marish bits. Though she was tempted to lean back and thrust a hand into her panties, doing so wouldn’t necessarily do her any favors - in fact, it was probably the worst thing she could do. Any act to touch her loins, whether it was warranted or not, would guarantee a sound ribbing from Celestia and possibly from Rarity as well, so she bided her time and considered her options.

Wondering if Celestia or possibly even Shining had slipped something into her underwear, she bolted to her feet. Whatever the heck was touching her had stopped simply rubbing her marehood and was doing its darndest to sink into her. While she turned in place and pawed at herself, thrusting one hand to her groin and the other to her tush, her anxiety went through the roof.

Standing up, Celestia placed a comforting hand on her arm. “Ants in your pants?”

“There’s something…” The words died in Cadance’s throat when she looked over.

She’d assumed Celestia was worried about her, but the look on the older mare’s face smacked of something all the more concerning. As she glanced over to Rarity and was greeted by a similar expression, a cold knot formed in her stomach. Her friends, two mares she trusted more than almost anypony in the whole wide world, appeared anything but anxious about her inexplicable plight - no, it seemed like they were on the verge of laughter.

Rarity rested her chin on her hands as she leaned forward. “What’s wrong, dear? You seem a little tense.”

Willing herself to ignore the thing, whatever the hay it was, that was prodding her entrance, Cadance scowled. “What did you do?”

Celestia reeled back and clutched her bosom. “Whatever do you mean, Cadance? Neither Rarity nor myself would ever do anything to harm you!”

“Quite right,” Rarity chirped.

“That’s a load of horse apples and yoooooooo - Oh buck!” Cadance groaned as her marehood was forced open.

With her knees buckling and heart racing, she stumbled to one side and grabbed the booth’s guardrail to support herself. What in the heck was going on?! She could understand if somepony had surreptitiously hidden a vibrating egg in her panties, even if she didn’t know how they could do it without her noticing it, but she was dealing with something far larger than a simple toy. Involuntarily contracting around what she swore was the broad head of a stallionhood, she sucked air through her clenched teeth and trembled.

“Looks like she’s struggling a bit,” Rarity remarked.

“I’m sure she’ll be fine ~” Celestia snickered, “won’t you, Cadance.”

Cadance fought through the strangely pleasant sensations accosting her and squinted over at the pair. It was as plain as day that Celestia and Rarity were at the very least aware of whatever was going on with her, if not directly responsible themselves, although that gave her no hints as to what was happening. Inadvertently glancing down at the crowd, she noticed several paces peering up at her in curiosity.

This was bad - really, really bad. The obvious solution would be to run off to the mares’ room, strip down, and figure out what was sinking into her depths, but that wasn’t exactly possible. Given that her dress was the only thing keeping her inordinately full figure in check, getting undressed wasn’t something she could easily do - plus she was pretty sure there wasn’t a restroom stall in the building that could accommodate her immense, unrestrained girth! As the mysterious intruder sank deeper and ground against her g-spot, she groaned then immediately clamped a hand over her muzzle.

While she didn’t understand what was happening, she knew one thing for certain - it was far more enjoyable than she dared to admit. To say she was troubled by the unforeseen and lecherous development would be an understatement - nevertheless, her body reacted to the sudden and quite passionate intrusion in an altogether different light. Winking and leaking nectar down her inner thigh, she impulsively bucked her hips.

“What,” she hissed, whipping her head around when Celestia’s hand glided up to her shoulder.

Grinning from ear to ear, Celestia leaned in. “Just relax…”

“How can you tell me to relax when - wait,” Cadance croaked.

It wasn’t something gradually filling her, it was somepony. For as long as she’d been with Shining Armor, having dated him for years before making it official and tying the knot with him, she was intimately familiar with everything about him - bearing that in mind, after calming herself enough to focus on it for a moment, she could recognize his stallionhood from feeling alone. She wanted to be angry with her husband and the pair of conniving mares who obviously had some hand in her lecherous harassment, yet the onslaught of pleasure, yet the bolts of pleasure coursing through her made it all but impossible to be upset.

Shining’s endowment was a gift, the type of stallionhood that inspired poets and sculptors, and its every minute detail had been all but literally plowed into her mind. With a subtle upward curve, an angry vein that ran along one side, and a slight taper that she’d unwittingly committed to memory, her hubby’s cock had seemingly been made to hit every sensitive area in her depths. Tightly squeezing the base of his shaft, she falteringly exhaled and tried not to draw any attention to herself.

Making a scene was the last thing in the world she needed. With a pair of Royal Guards stationed just outside their box, only a few dozen feet away, and hundreds of ponies in attendance for the graduation, the circumstances were precarious at best and possibly catastrophic at worst. While the chances were relatively slim that anypony would pay her any mind, getting too loud, stumbling off to a bathroom, or teleporting away from the ceremony without a darn good excuse would raise questions and make her look bad.

“You’re - Nnnnph - an ass,” she growled, glancing between Celestia and Rarity.

“Don’t be so prudish, darling,” Rarity tittered. “I’m sure that if you were given the chance, you’d do the same thing to Celestia.”

Celestia nodded as she eased herself back down and gestured to Shining’s chair. “I’m sure she would. Rarity, feel free to keep Shining’s seat warm until he gets back.”

“With pleasure!” Rarity sang, standing and hopping into open chair just behind and to the right of Cadance.

“And you,” Celestia continued, sending power into her horn, “why not make yourself comfortable…”

Lifted and pulled back into her seat, Cadance fought to contain herself. Even though Shining hadn’t fully hilted himself, plunging into her at a snail’s pace, the sensation of fullness

Though it was a relief to understand what was happening, she still couldn’t wrap her head around how it was happening - as such, she took the only reasonable course of action.

“M…magic - Buck - dildo?” she wheezed, looking over to Celestia’s smug face.

“Nope,” Celestia hummed. “It’s actually your husband.”

Cadance gasped and shuddered when the fat tip of stallionhood pressed against her womb. “H…how?”

“Portals,” Rarity glibly stated. “For the past month or so, I’ve been working with Celestia to construct a very special pair of panties that would allow her to service Shining when they were separated - granted, I hadn’t intended to use them as a prank, and I was going to surprise you with a pair for yourself, but the notion of this little trial run was simply too perfect to pass up! I do hope you’re not cross with us…”

“It’s fine,” Cadance breathed through gritted teeth.

It was, in fact, anything but fine, but she wasn’t going to proclaim she’d reap vengeance on either of them. Heaving air into her chest, she gripped the sides of her seat while trying and failing cataclysmically to gather her thoughts. She had to presume Shining was hiding away somewhere, quite possibly in a bathroom stall, languidly plowing a sex toy that was linked to per panties, although where he was and what he was using hardly mattered at this point - what did matter was that her bestial urges were steadily eclipsing her higher functions.

Of all the treachery she was suffering, from Rarity and Celestia flanking her and watching her endure her sensual torture to her husband off rutting her at a distance, her body’s betrayal was by far the most annoying. Though she consciously knew she should leave, she simply couldn’t. Rocking her hips forward and back, she tightly squeezed around his retreating shaft.

“I bet he’s loving this,” Celestia cooed, reaching over to massage her breast.

“How could he not?” Rarity purred as she lovingly fondled her opposite bosom.

Merely having Shining’s colossal cock in her would have made responding a trial, but being pawed at by a duo of devilish mares made forming a coherent thought a herculean endeavor. Groaning and rolling her head back, she spread her legs ever so slightly. It was a darn good thing that her gown was as good at concealing her proportions as it was, because the scene would look dramatically different if it wasn’t.

From an outsider’s perspective, she must have appeared as a mare suffering through a bout of minor hyperventilation, breathing hard and blushing heavily, although that couldn’t have been further from the truth of the matter. Effectively acting as a living, breathing cock-sleeve for her husband, a stallion who’d endowment could rival even that of a fully grown dragon’s tool, it took everything she had not to start moaning and playing with herself. As she held onto her seat for dear life, her tormentors grew more brazen.

Sliding one hand into her top, Celestia rubbed the bare fur of her tit. “I wonder what would happen if - excuse me, when he cums…”

“I suppose my craftsmareship would be thoroughly tested -” Rarity sighed, lightly pulling at the hem of her dress, “then again, a bit of a stress test may be intriguing. Honestly, I’m more interested to see if little Cadance here will be able to outlast her dearest hubby…”

“To - Mmmph - Tartarus with both of you,” she seethed.

Why - why was this so much hotter than it had any right to be?!? She’d been involved with threesomes before, and it was hardly the first time she’d done something erotic while out in public, yet she could already sense herself inching to a climax. Whether it was from her surroundings, that she had to keep her voice down, because Rarity was suddenly involved, the portal in her panties, or some wild combination of those or other factors she couldn’t account for, her ordinarily impressive endurance crumbled away and slipped through her fingers.

Clamping her eyes shut, she fought to think of something - anything to delay the inevitable - unfortunately for her, her plan backfired spectacularly. Her mind dwelled on Shining, imagining him seated beneath her as he bucked his hips and pounded her from below. The din of the crowd, the stadium around her, the delicate, marish fingers wandering over her shivering frame - all of it disappeared as she envisioned herself with her lover and him alone.

Losing a little more of herself with each of his thrusts, her breaths came harder and her heart beat faster. No matter where she was or what she was doing, if Shining saw fit to feel her embrace, it was her duty - no, her privilege to serve him. Fighting his backstrokes, yearning to have him as deeply as possible, she bit her bottom lip and teetered on the precipice of release.

“I think she’s close,” Rarity whispered.

Bringing her muzzle to the side of her head, Celestia breathed hotly on her ear. “Cum…”

Like some sort of spell being cast, the word was her undoing. She arched her back and spasmed, unleashing a torrent of marish juices over her seat and to the concrete beneath her, while she whimpered. The logical side of her told her she didn’t have too much to fear, what with Rarity and Celestia being the only two who could actually see her clearly, although climaxing in such a public setting was as ignominious as it was thrilling.

Wheezing and nearly cross-eyed, she had to force herself to grimace. “You’re the worst - both of you…”

“Wait until he’s finished before you hurl accusations like that,” Celestia mused.

“Verily,” Rarity agreed. “He’s only just getting started…”

Cadance fought to recover as Shining picked up speed. Her gargantuan bosoms, once safe and arcanely concealed within her gown, threatened to spill out and into the open, while her plump thighs strained the fabric over her legs. Her climax, for as wondrous as it had been, had made her expand in several areas, although she was far from the only pony making a scene.

Practically plastered against her side, Celestia teased her while getting herself off. Her right hand had disappeared between her thighs, while her left lightly tugged at her top. While she hadn’t overtly done anything to threaten the integrity of her own dress, her enthusiasm would see her pushing her attire to its limits. As if by an ironic twist of fate, moments after Cadance’s eyes fell on her, she grabbed the top of her dress and hauled it downward.

Celestia’s breasts practically exploded out into the open, defying reality and being liberated from their stifling confines. Each monolithic tit was roughly as big as a pony’s torso, driving her back in her seat and filling nearly a third of the booth, although she hadn’t just whipped them out for show. Lifting and beckoning with one finger, she set her sights on Rarity.

Rarity only hesitated for a moment before shifting her attention over to the behemoth bosoms that had been presented to her. She may have been a fraction of Celestia or Cadance’s size, no larger in stature than any ordinary pony, but the fondness she’d developed for rich, borderline decadent Princess milk had done wonders for her figure. With pudge in all the right places, a head-turning derriere, and a rack that sat heavily on her chest, she was, in spite of not being a mother herself, the quintessential definition of a MILF.

“Let me just - Whoops!” she melodramatically squawked as she sidled by Cadance and wrenched her top open. “Do excuse my butterfingers…”

Cadance would have bet every bit in the royal coffers that the accident had been anything but intentional, but she had bigger issues to deal with - namely the massive stallionhood rearranging her insides, toeing the line of a second orgasm, and finding it very, very difficult to look away from Celestia’s exposed, head-sized, leaking nipples. Though she hadn’t been hungry minutes prior, the sight of so much warm, sweet milk flowing from her mentor-made-lover’s tit made her mouth water.

Shifting slightly, Celestia used a combination of her magic and hands to tauntingly shake her breast at her. “Go ahead…”

Cadance glanced out over the balcony and scrunched her snout. “One sec…”

Acting with haste, she cast a simple noise barrier and an illusory spell to shroud the VIP box from prying eyes or ears. She’d just wanted to attend the graduation with Shining, Celestia, and Rarity, to have an innocent little outing to celebrate the newest batch of Guard recruits, yet things had gone well and thoroughly off the rails - so much so that she knew there was no salvaging it. Turning and draping herself over the proffered bosom, she bounced on her seat, milked her husband’s cock, and ran her tongue over her fellow Princess’ areola.

“So good,” Rarity muttered.

Cadance glanced over and saw that she was no longer the only mare enjoying herself. With her tits flopped out and squatted down, Rarity unabashedly fingered herself while gulping down mouthfuls of Celestia’s milk. To see the ordinarily well-mannered and refined couture acting in such an uncouth fashion would have been disconcerting, if it hadn’t been as stimulating as it was.

Realizing that things had crossed the point of no return, that herself, Rarity, or Celestia would have to leave the colosseum via teleportation, if only to avoid the public seeing them in a disheveled state, she yielded to her urges. Each gulp sent a river of milk down her throat and into her stomach while she fiercely gripped Shining’s incredible shaft. Not-so-stealthily having sex with two of the hottest, most curvaceous mares in the planet as her husband furtively fucked her through a portal in her underwear was definitely a first for her, but she could already tell that it wouldn’t be the last time for such a depraved tryst.

Muffling an ecstatic howl by cramming Celestia’s nipple into her muzzle, she was rocked with a second, even more powerful climax. The sheer amount of pleasure she was experiencing would likely drive any other mare mad, although her innate abilities, those linked to her being the Princess of Love, allowed her to maintain her sanity and savor the moment - if only just. As she drank deeply and greedily, like somepony who’d just wandered out of a desert, the sound of popping seams and tearing fabric went unnoticed.

“Here,” Celestia breathed, reclining and causing her mammoth breasts to fall to either side of her chest, “let me help.”

Being the oldest and most composed member of the trio, along with her mastery of sorcery, gave her an edge that she was all too willing to wield against both Rarity and Cadance. As she called upon her magic, her golden aura surrounded the mares’ bosoms and nethers. She began to laugh as her colleagues mewled, amused and aroused by their reaction to the additional stimulation, until her hubris bit her squarely on the ass.

Though neither Rarity or Cadance were in the best situation, with the former half undressed and the latter coming down from an orgasm, their counteroffensive was nothing short of savage. Their magic mingled and hit Celestia with full force, plowing her with a sorcerous stallionhood while toying with her clit and giving her a full-body massage. They may have been on the cusp of delirium, but neither would let the wizened demigod go unpunished for her perverted transgressions.

Safe and secure within the enchantment Cadance had carefully cast, the trio became more and more passionate. Celestia howled out and spasmed as she came, pushed past her limit as both her bosoms were suckled upon, while Rarity and Cadance gagged and sputtered around the colossal nipples they were nursing on. The ceremony was only a few dozen yards away, they were in the last place anypony should become intimate, and yet they forgot all about where they were and what they were supposed to be doing.

Cadance recoiled, swallowed her mouthful, and covered her muzzle as she demurely burped. “I don’t think -”

Riiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiip

Mid-sentence, her dress detonated and was reduced to rags. The combination of enchantments and eldritch fabrics, coupled with her growth caused by her welling passion and influx of several gallons of milk, turned her dress into a bomb of sorts - a harmless bomb that rained glittering shreds of fabric around her, but a bomb all the same. Her distended, incomprehensibly gravid belly pushed her thighs apart and came to settle between her feet, her tits almost pushed Rarity off the balcony, and her ass crushed the chair she’d been seated on into nonexistence, reducing it to atoms, while she toed the line of a third orgasm.

There was no reason to hold herself back at this point, positively drenched with a mixture of marish nectar and breast milk, but that didn’t stop her from trying to retrain herself. Slowing her breathing and bucking her tush on the concrete beneath her, she delicately bit down on the teat in her nearly dislocated jaw and earned herself a squeal of delight. Celestia’s rack may have been a touch bigger than hers, although that may change if she kept getting bigger.

“Aaaaaaaghn!” Rarity screamed as her knees quaked and she fell forward onto Celestia’s breast.

Hearing her friend cum chipped away at Cadance’s resolve, but her self-control disappeared when she looked over. Rarity’s gown had burst down the middle, unveiling her sagging, gurgling belly. Seeing her friend’s doughy belly, imagining that it was filled with a foal and not just milk, brought her to the gates of nirvana in the blink of an eye.

She brayed to the heavens, her toes curled, and her eyes rolled back as her figure ballooned outward. The prophetic notion she’d had moments before, that it wouldn’t be impossible for her to eclipse Celestia’s figure, was proven all too true. Now bigger than her fellow Princess, doughier and larger in every way, she wailed uncontrollably and was beset with rapture.

Celestia climaxed a split second after her, adding her blissful howling to the cacophonous symphony, and grew as a result. It was silly to think that it was some fashion of competition, that the alicorns were trying to outdo one another, although that’s essentially what ended up happening. Sandwiched between the two titanic and soft mares, pinned in their cleavage and against their bellies, Rarity wailed and thrust a hand to the heavens.

Glancing down and seeing an alabaster hand protruding from her bosoms, Cadance shrugged. Judging from just how intense Rarity’s climax had just been, she wasn’t all that worried about her friend. Shifting her attention back to Celestia, now that one mare had been essentially dealt with, she set her brow and forced a grin.

“Your turn,” she growled, focusing her energy on the Princess.

Amplifying her magic, Celestia pulled out all the stops. “You first…”

Now, unlike minutes before, it was a competition between them. Dueling with pleasure and with folds of yielding flesh spilling over the balcony, the alicorns pitted themselves against one another without restraint. As quickly as one would be stricken with an orgasm, the other would follow moments prior, until they were both cumming at a startling rate. With every climax came new growth, filling the entire area until it resembled a concrete swimming pool of breasts, bellies, milk, and two panting, semi-coherent Princesses locked in carnal combat.

Cadance thought she’d gained a slight advantage after Celestia spasmed endured her umpteenth orgasm, but any edge she held was lost when she sensed Shining throbbing within her. The devastating realization that she was about to be filled with an inordinate amount of foal-batter came several moments too late to do anything other than brace herself. Sensing him flare against her womb, she was wracked with blinding ecstasy when he erupted inside her.

Getting creampied by her beloved always - always did her in, and this time was no exception. With her mouth hanging open in a silent scream, she came with the full fury of a collapsing star. Her mind went blank, her limbs fell slack, and any determination she had to conquer Celestia withered away to nothingness. It would have been bad enough to have victory snatched from her clutches, but then she heard it - the unmistakable and terrifying crack beneath her.

It took every ounce of strength she had to summon her power. If there was even the slightest chance that the balcony Celestia, Rarity, and herself was on would collapse, there would be more than just their lives at stake. Tweaking the shrouding spell’s workings, she magically flung the VIP box and everypony in it to a remote glade outside of Ponyville. Would a duo of Princesses winking a section of the colosseum out of existence raise questions? Yes, undoubtedly so, but it beat potentially sending somepony to the hospital.

Celestia yelped as she went crashing to the earth and rolled onto her back. Fairing no better than the startled alicorn, Cadance landed and levitated Rarity onto herself as she landed with an inglorious flop. If nothing else, her size made her a convenient and startlingly effective landing pad for the incoherent unicorn entombed in her bust.

“T…truce…” Celestia rasped.

“Truce,” Cadance wheezed, lifting a shaky thumbs up.

In a flash of light, Shining appeared with his dick buried in what appeared to be a fuck-toy. “What the heck just…oh…”

“Hi, honey,” Celestia and Cadance groaned in tandem.

The Princesses looked at one another, snickered, then broke into outright laughter. They’d made a spectacular mess of things, including themselves, and they’d likely caused several thousand bits worth of damage, but there was no sense crying over figurative or literal spilt milk. Between the four of them, they could come up with a semi-believable explanation for their abrupt departure - if they couldn’t, it wouldn’t be the end of the world. Dreamily looking up as Shining came over to check on her, Cadance smiled. No matter what happened next, or what sort of fallout she’d have to deal with, she was glad that the graduation hadn’t been as boring as she’d predicted…

Epilogue

Closing the door behind him, Shining unbuttoned his shirt and gradually stripped out of his clothes. On any other day, Cadance, Celestia, or both would have been in the room to greet him and help him get out of his stifling uniform - regrettably, that wasn’t the case. With the Princesses away in Canterlot, tending to some delegation from Griffonstone, he was left to his lonesome to tend to the castle and the Crystal Empire.

He slowed by the vanity to wriggle out of his pants. Darn clothes - ever since he’d ended up with a duo of deliciously curvaceous alicorns to tend to, his life had gotten a lot more complicated. Most of the changes he’d adapted to were fantastic - heck, better than fantastic, having a pair of foals on the way and better sex than most stallions could ever dare to dream of, yet there were a few niggly drawbacks.

Hearing a seam on his slacks pop, he snorted and rolled his eyes. Fantastic - he’d ruined a second pair of slacks in less than a week. While he’d initially thought that having a pair of lovers had boosted his virility, particularly because one was the Princess of Love, he couldn’t shake the feeling that there was something more at play. His frame had grown considerably, he both looked and felt younger than ever, and his stallionhood - well, his stallionhood was an issue in and of itself.

While he watched the titanic length that was his endowment swell and twitch at his groin, his thoughts darkened slightly. As much as he loved being exquisitely well-hung, being able to satiate Cadance and Celestia with ease, the cost to his wardrobe was not insignificant. Even if he didn’t end up getting any bigger, he was probably going to have to pay Rarity a visit so he could order some attire that could accommodate his gifted size.

On top of his lack of any meaningful relief, something was wrong with him; he’d initially thought he was just lonely, having grown spoiled by having a pair of magnificent mares at his beck and call at a moment’s notice, but there may have been something more to it. It was like he’d been suffering from a mental fog since Cadance and Celestia had left.

Shortly after his lovers had departed, a lethargy had settled over him. Nothing he’d tried, including pulling extra hours with the guard or busying himself in the castle, had helped - in fact, his predicament had only grown worse. As he lowered a hand and idly stroked his shaft, his eyes drifted closed.

He was probably just lonely - lonely and horny. Cadance was an amazing wife, never failing to tend to his needs, but having Celestia around had really upped his sex drive. Both of the Princesses were practically insatiable, requiring his affection on a regular basis, and he’d simply adapted to serving them - yeah, that had to be what had him out of sorts. Without a lover to fall asleep with and wake up to, anypony would be feeling off - that made sense.

He shook his head and rubbed his eyes, annoyed with the development and frustrated that he had no way to get any relief - sure, his hands were always an option, but jacking off felt downright lackluster compared to sinking his length into the balmy, velvety depths of either of his lovers. Marching to and into the bathroom, hoping a cool shower might clear his head, he slowed when he caught his reflection in the mirror above the sink.

Though he’d always considered himself a humble stallion, enjoying his time with the troops and the citizenry at large, he had to admit that he looked good - darn good. His physique was nothing short of adonic, the sort of figure that a stallion could only attain from a lifetime of dedicated time in a gym, and the sight of it brought a smirk to his muzzle. Flexing his arms and pecks, he chuckled and continued on his way.

He may have had it kinda rough, but he knew good and gosh darn well that Cadance and Celestia were as bad off or worse than him. Going for even a single day without his intimate company would drive either of the mares up a wall with desire, reducing them from regal Princess to lust-crazed beasts, so he couldn’t imagine how they were managing to get by. Maybe they were keeping one another preoccupied, or perhaps they’d grown so desperate that they’d ask Twilight for a bit of magical relief - either way, as soon as they got home, he felt reasonably sure that they were going to jump his bones.

Having set the water in the tub to warm, he stepped into the basin and beneath the running showerhead. Irrespective of his troubles, there were few things more refreshing than a long, relaxing wash after a long day - even if that long day would ultimately end with him in bed by himself. As he grabbed a bottle of shampoo to lather his mane, his mind wandered.

At the rate he, Cadance, and Celestia were going, there was a very real possibility that they were going to need to convert several guest rooms in the castle into nurseries. It was a bit funny - years prior, before Flurry had come into his life, he’d been terrified at the prospect of being a father, but his stance had changed on that matter. If his lovers wanted more foals, and he had no reason to presume the nigh-immortal alicorns wouldn’t, he’d be more than happy to fulfill his role.

He went motionless and blindly turned his head toward the door as a noise crept to his ear. It was hard to tell what he’d heard, but it sounded like a door had just closed from within his bedchamber. Rinsing off and wiping his face, he wiped a hand along the steamy glass partition of his tub.

“Hello?”

Waiting for a response that didn’t come, he pursed his lips. Maybe he’d been hearing things - if he hadn’t, there was a chance that one of the castle’s staff or a guard had merely left a message for him. Thinking nothing of the matter, knowing the worst he’d have to deal with was a small interruption, he lazily continued his shower.

Even moving at a leisurely pace, taking his time and enjoying himself, it didn’t take him long to get cleaned up and toweled off. Without his paramours to keep him company, what remained of his evening was completely and totally free. Musing on if he should go out to eat or simply order a meal delivered to the royal suite, he traipsed out of the bathroom.

“Hello, lover,” a lilting voice softly breathed.

Shining faltered and his eyes shot to the bed. Atop the mattress, resting on her side in what he could only describe as a provocative pose, was Cadance. Her heavily-lidded eyes dance up and down his naked body, a sinful smirk graced her muzzle, and a throaty, sensual hum escaped her. Stumbling upon his wife was nothing new - in fact, he’d done it more times than he could possibly count, although there was something particularly off about her.

Making no move to cover himself, he squinted over at her. She looked as phenomenal as ever, a veritable bombshell of a mare, although she was no longer gravid. With a slim waist, utterly gargantuan breasts, and foal-bearing hips that would tempt even the most devout husband to sin, she appeared anything but pregnant.

She moved slowly, lifting and bending one leg to shamelessly reveal her nethers. “Something wrong, Shiny? You look tense…”

Tense was one way to describe how Shining was feeling, although not in a metaphorical sense. The sight of his wife laid out, clutching one monumental bosom while languidly caressing her plump, succulent marehood sent blood coursing to his loins. He presumed that this was some minor cantrip, a spell to make her appear as though she wasn’t pregnant, because the sheer nightie covering her left nothing whatsoever to the imagination.

“Can you really blame me for excusing myself?” she sighed while shamelessly playing with herself. “Those talks with the griffons are so dreadfully dull. I’m sure everypony, including Celestia and that sister of yours, will forgive me for coming to check on my big, virile hubby ~ wouldn’t you say?”

Shining licked his lips and inched toward the bed. “I…I don’t see why they wouldn’t…”

“Exactly,” she hissed and shivered as her fingers danced over her winking clit. “Simply thinking about you through those boring talks was enough to get me distracted - see…”

Turning his eyes to her marehood, he licked his lips. The chances of her getting in trouble for briefly shirking her royal duties were slim, he hadn’t gotten laid in the better part of a week, and it wasn’t like anypony would give him or his wife flak for indulging themselves with one another - besides, a quickie wouldn’t take too long. Casting his inhibitions to the wind, he scampered to the bed.

“Ah ah -” she tutted, stopping him before he could dive between her parted thighs, “allow me to warm you up first.”

He gave a small shrug, knelt on the mattress, and laughed. “Won’t hear me complain about that.”

Turning and getting onto her hands and knees, her breasts hanging heavily and weighing heavily upon the sheets, she made room on the center of the bed. “By all means, make yourself comfortable, darling.”

“If you insist,” he purred. Caressing her cheek as he passed her, he rolled onto his back and slipped his hands behind his head. “Somepony’s feeling affectionate.”

“You have no idea,” she pouted as she crawled over his outstretched legs. Lowering her head, she buried her snout in his balls, drew a deep breath through her nose, and groaned. “I’ve missed this…”

Rolling his eyes, he shook his head. “It hasn’t been that long, but I’ve missed you too.”

“Oh I’m sure you have, more than you can possibly imagine,” she murmured.

Keeping herself propped up on one arm, she lazily stroked him off with her free hand while licking and kissing his immense coin purse. He’d secretly hoped that something like this would happen, keeping his fingers crossed that she or Celestia would fold and spontaneously pay him a visit, and he was overjoyed that his wish had been fulfilled. Was it silly that he’d wanted either of the Princesses to come see him? Yes, admittedly, but that wasn’t wholly his fault.

Closing his eyes and savoring her affection, he relished the feeling of her warm, wet tongue gradually moving up the underside of his shaft. Cadance and Celestia had spoiled him, there was no simpler way to say it, and he wouldn’t deny he’d grown quite fond of their monstrous libidos. As far as he was concerned, having not one but two goddesses at his beck and call, he was the luckiest stallion on the planet.

She moved silently, save for the occasional groan or contented sigh, until she pushed herself up and reached the top of his enormous shaft. Peeking down at her with a single eye, he watched as she virtually inhaled his prodigious length. The sensation of her snug gullet was divine, better than he remembered it being, and it caused him to stifle a moan of his own.

Watching his stallionhood disappear into her face while she lowered her head, he fought the urge to buck his hips. “Just don’t tell Cele you snuck away to visit me - she might get jealous.”

Unable to speak, Cadance winked up at him before fully hilting him in her snout. It may have - no, it had to be his brain playing tricks on him, but this felt different. Her throat was tighter, her technique wasn’t exactly the same as it usually was, and there was something odd about her he couldn’t put his finger on. Dismissing his concerns, he reached up to pull a pillow under his head.

Cadance was even more fervent than ever, swabbing her throat with his girthy cock while clutching and kneading one udder. The meeting she’d been stuck at really must have been mind numbing, because she hadn’t been this enthusiastic to choke on his dick in - well, he couldn’t remember the last time she’d been this enthusiastic! Seeing no reason not to give her what she wanted, he lifted his legs, planted his feet, and started lightly thrusting into her muzzle.

Her eyes rolled, her nostrils flared, and he’d bet every bit in the royal coffers that she was positively drenched - in short, his efforts were immediately rewarded. Though he couldn’t say what had gotten into her, excluding his tool, he wasn’t about to question what had her so worked up. If she wanted to gag on him before presumably getting down to business, that was a-ok in his book!

Withdrawing slightly, she focused her efforts on the tip of his shaft while bringing her hand to the base of his length. Ok, yeah, this was unlike her. Normally, she’d rub herself as she blew him, if she wasn’t giving him a tit-job, but now she was putting all of her attention on him. Confused but amused, he snickered.

“Feeling extra thirsty ~ eh?” he quipped.

She freed her muzzle with a soft pop, swallowed a mouthful of his pre-cum, and licked her chops. “You have no idea…”

Giving him no time to say or do anything whatsoever, she set herself upon him with renewed vigor. Jeez - he almost felt bad for her. Between her unfamiliar technique and unimaginable zeal, he wasn’t going to last long at this rate! He set his jaw and gripped the back of his head, holding himself back while enjoying the spectacle and wondrous sensations she afforded.

The good news was that he didn’t prematurely blow his load before getting to actually fuck her - the bad news was that he’d had perilously little control over the matter. Reading him like an open book, Cadance masterfully kept him on the edge. It was maddening and thrilling, brought to his limit multiple times before she’d ease up, and it drove him wild with desire.

Rocking back and kneeling over his groin, she squeezed her breasts between her upper arms. “Had enough?”

He shook his head and locked eyes with her. “Not on your life…”

“Good,” she cooed as she shuffled forward. Moving up his body, she dragged her marehood up his cock. “I do hope you’re ready for this, Shiny, because I certainly am.”

Extending his arms, he ran his hands down her sides. “You know I am…”

The heat of her entrance against his cock-head was the final nail in his coffin. On any other day, at any other time, he would have returned her sexual torment, yet he was compelled to claim her. Simultaneously drove his hips upward while pushing her down and back. Her delighted whimper, deep and guttural, was the perfect accoutrement to the feeling of her slick, cool - wait…

Something was wrong - not with him but with the situation in general. Her depths felt incredible, silken and taut, but she was much, much cooler than she should have been. Could this be a byproduct of whatever enchantment she’d used on herself. Only just concerned enough to ask if she was alright, yet having no desire to bring an end to their tryst, he quirked a brow.

“Are…are you feeling ok?” he stammered, desperately attempting to restrain himself.

Leaning forward and pressing her mountainous chest against his pecs, she nibbled his ear. “More than ok, my sweet.”

The moment she finished speaking, she threw her weight back and fully impaled herself. The sensation of her cervix grinding against the tip of his length was enough to dull his senses and rouse the most primal portions of his mind. What had he been thinking? Of course she was fine! Snickering to himself, he turned his head to make out with her. Whatever was going on with her clearly hadn’t affected her in any negative way, she’d taken the time to come see him, and she was obviously eager to tend to his stallionly needs, so it was his right - his duty to give her what she craved.

He moved in perfect harmony with her, thrusting up to meet her descents while she fucked herself upon him. It was a shame that she wasn’t going to be able to spend the entire night, likely having plans for the following morning with her fellow royals and politicians, because he would have gladly rutted her until the sun rose. Hammering into her from below, his balls smacking against her supple tush, sank his tongue into her muzzle.

Fiercely gripping his shaft, acting like she hadn’t felt his touch in years, Cadance broke the kiss and leaned back. “Allow me…”

He’d always been more than a match for her in bed, his carnal prowess being one area in which he could best her, yet he found himself struggling to keep up with her. Though it was impossible, she was actually managing to overtake him in bed - something which had only ever happened a very, very small number of times before. Torn between watching her beauteous face, wildly swaying bosoms, and juicy marehood milking his cock, he whimpered.

If he hadn’t known better, he’d say he was fooling around with a totally different mare - that or he’d somehow lost decades of endurance and sexual experience. It would have been baffling enough to have his wife overpower him, but that was only the tip of the iceberg - to make matters worse, it almost felt like he was getting weaker. His limbs grew heavy, his thoughts hazy, and it was getting increasingly difficult for him to move at all.

“Somepony’s - Aaaaaaghn - getting close,” she tittered like a naughty schoolfilly.

He hadn’t even realized he was crossing the threshold of a climax until he was beyond the point of no return, although that wasn’t what troubled him - what troubled him was the sudden understanding that she hadn’t cum a single time. Even though they’d only been at it briefly, no more than ten or twenty minutes or so, it was unthinkable that she hadn’t orgasmed at least once by now.

There was a point at which any stallion, even a Princely stud, would break - for shining, that moment came when a harlequin light flickered across her eyes. His climax was ruinous, devastating him on an existential level, and it was one of the most powerful he’d ever had. The only time he’d ever cum harder was when he’d been kidnapped by - oh no…

Willing himself to look up at her, he finally saw her for who and what she really was. She may have been a perfect reproduction of Cadance, but the Princess of Love she was not. There was a single being on the planet who could do something so audacious, to slip into a castle to make wanton, bestial love with him of all ponies.

“C…Chrysalis,” he rasped, his voice hoarse and barely a whisper, “y…you won’t get away with - Cough - this…”

Though she retained her form, parading herself as his wife, her emerald, cat-like eyes revealed themselves for a fleeting instant. “But I already have, dear Shining, I already have…”

His vision tunneled, the world faded to black, and he slipped into a harrowing, rapturous oblivion. He’d fallen right into her clutches, and he had nopony to blame but himself. The final thought to grace him before he succumbed to nothingness was that is one - his only hope was that Cadance and Celestia would be his salvation…
