Royal Breeding

Princesses Twilight Sparkle and Celestia were kissing passionately on one of the couches in the main room of Golden Oaks Library, giggling like fillies whenever their mouths separated. Their entire body language at the moment was entirely devoid of the properness and eloquency expected of them in public, but really, who could blame them? Such manners seemed daft in the heat of the moment.

The alicorns started their make out rather chaste, little more then a peck on the cheek, but it had quickly spiraled out of control, as they now begun to strip each other, pulling off their rather risque dresses they had on for whatever social gathering they were just at (they couldn’t care less what it was at the moment), and pressing their rather large breasts into the other’s. Their limbs became entangled as they hugged each other tightly, then started to roam around the other’s body, their hands and thighs generally working towards the other’s ass and sex respectively.

They next began grinding their crotches into the other’s leg, forcing moans out of their throats and into the other’s, which only enhanced their pleasure. The mares’ lust was ravenous, which made some since given how their arousal had been steadily building over the past few hours and only now had a vent.

Twilight remembered the event they were at previously in minimal detail, mostly due to how she was pretty much entirely focused on her crush, who was wearing a dress that could rather aptly be described as lingerie. Thinking back on it though, the purple mare seemed a bit of a hypocrite given how her dress was also rather (okay, extremely) revealing. She never really imagined that her crush on the solar princess would be reciprocated so strongly, but it appears finally having another alicorn whom she could be sexual attracted to without major public contempt and already knew rather well had allowed her to release more than a millennia worth of sexual tension.

All of the build-up that the alicorns endured from how much they were teased in the event, on top of their prior lack of sexual partners, had made them extremely eager for relief. So much so, that hardly half a minute had passed before the lilac princess began sliding her body down her lover’s, her kisses slowly, but no less passionately, trailing down from the lips of the white mare, across her chin, neck, top of her left breast, before finally landing on her nipple.

Twilight’s right hand slid up and around Celestia’s torso to land upon and grasp the mammary in the former mare’s mouth, squeezing and kneading it as she began to suckle on its nipple. She involuntarily paused her ministrations when a warm, wet pressure went up her horn, the pleasure making her moan loudly, even if rather muffled. The studious pony resumed her suckling, continuing it through the next lick across her horn, but the moan it incited lightly vibrated the breast in her mouth. The vibrations made the other mare wrap her mouth around the lavender horn and moan, vibrating it, and thus creating a increasing spiral of pleasure.

The spiral wasn’t enough to make the princesses climax on its own, however. And so aside from their continued suckling, sucking, and moaning, the ponies maneuvered a hand each to the other’s sex and thrust a pair of fingers in. They then thrusted their fingers out and back in repeatedly with haste, making their pleasure rocket skywards and their moans louden. Their pleasure kept building and building, their muffled moans and gasps becoming near-orgasmic in nature, until-

“GAH!”

Twilight woke with a start, her senses dulled to the point where she couldn’t recognize anything around her. She sat up, only to find she had a massive headache, paining her so much she doubled over and clutched her head with a hand while she laid back down.

She now realized her actions with the solar princess were naught but a dream, only adding fuel upon the fire of misery and pain she now found herself in. She continued to lay down, on the brink of crying from the sudden sensations, allowing her senses to slowly sharpen and her pain to dull to where she could finally sit up and not feel like she was about to die.

She looked around the room she found herself in, sensing it to be rather dark with green lights scattered about. She next saw something really big and pink near her, and scooted along the ground a touch, but stopped when she felt how rough it was. She looked down at her body, finding pure lilac there with the moderate curves of her naked body. Wait...

The lavender alicorn screamed as she jumped backwards and wrapped an arm around her breasts and another pressed to her crotch to cover her nipples and sex respectively. She glanced around the room again, her sight sharpened from her outburst, and saw the large pink thing again, now finding it to be vaguely anthropomorphic. It seemed like a pony in most aspects, with a primrose, mulberry, and purple tail and a crystal heart cutie mark, but its belly was absolutely massive. She took a moment to think about the colours and the mark, attempting to place its owner, and before long it clicked.

“Cadence!” Twilight shouted as she quickly got to her hooves and made her way over to the other princess. She knelt at the pink mare’s side and took her shoulders in her hands and shook lightly. “Cadence, wake up!” She yelled at the other mare, who quickly stirred.

“Mmf, Twily?” Cadence asked dazedly and stretched her limbs, then gazed at the purple pony. “Oh, hi Twily!” She said gleefully, and tried to sit up, but failed due to her gigantic belly.

“Um, are you alright?” The other alicorn asked concernedly.

“Mmm, n-never bett-AH!” The pink mare moaned as she hugged her tummy.

“Uh, a-are you sure about that?” Twilight responded, even more concerned now.

Cadence quickly nodded and replied, “Yeah! I t-think I’m just contractiiiIIIINNNNGG!!!” She screamed and threw her head back in a mix of pain and pleasure.

“Contracting?” The other pony asked, then gasped in shock as she realized what that meant. “W-wait, so, you’re pregnant!?”

“MMMMMMM!!” The pink alicorn moaned in response, being too overwhelmed to say anything intelligible.

“S-so, that means...” Twilight started, but was cut off as the other mare started screaming.

“AAAAAHHHHHHHHH!!! TWILY!!!” The princess of love yelled as she reached out and tightly grabbed the other pony. Her legs started shaking violently as she continued screaming, while the lilac alicorn leaned over as much as she could to attempt to see what was coming out of her snatch.

The volume of the yelling reached a peak for a moment, during which a large green egg, slightly larger than a watermelon, was forcefully ejected from the pink mare’s sex. Twilight stared at it awe and bewilderment as rolled along the rocky ground, before coming to a stop as its mother’s screaming reached another peak, this time slightly louder. Another egg was ejected after a moment, then another, then another, and before long it was nearly a constant stream sputtering out of the princess’ pussy.

The purple pony stared in sheer bafflement and terror at the display, peripherally noticing the pregnant mare’s belly slowly shrinking. More than a minute was spent watching the eggs blast out of Cadence’s womb before the alicorn’s yelling finally died down and she passed out, leaving the other princess to stare, unmoving and awe-stricken, at the preponderance of eggs strewn about the cave floor.

It took a few more minutes for the purple mare to break out of her stupour, leaving her to glance around the room and finally take it all in. The deathly black rock, the vibrant green crystals, and the overall chilly atmosphere gave her only one conclusion. She sighed in dread as she rested her head on the other pony’s deflated torso, completely at a loss for a plan.

At least, that was until an ominous and ambient cackling was heard echoing into the room, making Twilight jerk upwards.

“Well, well, well... It seems my first session has been a resounding success,” The maliciously sultry voice of Queen Chrysalis said. “Look at all my little changelings!” She exclaimed happily and could be heard practically skipping over to the opulence of eggs while the lilac princess deliberately avoided looking at her by returning her gaze to the mare below her.

“So...” Twilight started, “I suppose this,” She pointed to the eggs, “Is your plan this time around?”

“That’s right,” The queen replied as she begun to lean over the eggs, keeping her legs straight with her backside facing the her captives. “And, as you can see, it’s working perfectly!”

The alicorn meekly looked up to once again observe the wealth of changeling eggs produced from her dear friend, blushing when she saw the position the changeling was in. Her glance turned into a stare, however, when she saw the massive thing dangling in between her thighs. She gawked at the humongous stallionhood, her gaze utterly fixed upon its length and girth, engraving the finer details into her mind, such as the thick veins running along it, the flat head of the flare, screaming brutality and uncaringness, and the obscenely thick medial ring, separating the thick bottom quarter of the shaft from the slightly thinner remainder. The balls also caught her attention, their weighty plumpness, no doubt absolutely teeming with virile seed, and their sexual-without-bounds musk, so thick and powerful now that she noticed it, she could almost taste it.

“Like what you see, Twily?” Chrysalis asked seductively before slowly rocking her hips back and forth, causing her shaft to swing hypnotically, the connected balls making light smacking noises when they connected with the insides of her thighs.

Twilight began to drool as she continued to stare, to which the changeling’s response was to chuckle at how the supposedly unshakable alicorns were so easily enthralled by her not-even-hard stallionhood, then begin to back up slowly, keeping her ass pressed outwards. She reached the captive princess after a few seconds, her balls swaying mere centimeters from the her muzzle, their potent fumes wafting straight into her nose.

The purple pony continued to stare for several more moments, only blinking out of her stupour when she noticed the vivid green shaft moving slightly. She averted her gaze to it, seeing it start to bend slightly upwards and become harder, which notified her to the fact that the cock before her, for all of its gargantuan-ness, was still flaccid!

The alicorn closed her eyes and inhaled deeply through her nose to attempt to clear her mind, but only succeeded in getting her another smell of Chrysalis’s musk, making her cough and back up slightly from its potency. When she was done, she kept her sights on the other mare below her, refusing to look back up at the stupefying stallionhood in front of her.

The changeling queen sensed Twilight’s defiance, and with another chuckle out of how futile the mare’s efforts were, shoved her hips backward into the alicorn’s face, her hot balls smothering her prisoner’s muzzle. The lilac pony opened her eyes wide and inhaled sharply in shock, but her gaze quickly became half-lidded in lust as the pungent odor once again invaded her nostrils, shattering the last shards of her resistance.

The captive princess’ hands went from her fellow pony to the lower thighs of her captor, and took a moment to slide up to her balls at moderate pace. She then cupped them in her hands and pressed them into her muzzle to get more of that deliciously sensual musk into her system, before pushing her tongue out of her mouth and pressing it onto the sack and licking desperately.

Chrysalis let out a soft coo of pleasure from the sensation, then pushed her backside even further outward and bent her knees somewhat, beginning to nearly sit on her prisoner. The purple mare slowly started to roam her hands around the balls smothering her senses, caressing and lightly kneading them, making her captor moan nearly constantly. Her hands eventually started to travel farther, her right making its way to the similarly hot and obsidian-black base of the shaft, forcing her left hand and arm to encompass both of the plump balls.

Twilight wrapped her right hand around the changeling’s girth, briskly rubbing up and down below the medial ring with no real force, but making her captor’s moans escalate in volume regardless. Some precum began lightly flowing from the tip of the stallionhood as its balls were lightly compressed, slowly trailing its way down the length of the shaft before meeting the pumping purple hand. The precum felt cool in comparison to the cock from which it was borne, its slickness allowing the alicorn to apply more pressure while maintaining her pace.

The lilac princess begun moving her right hand farther along the shaft, rubbing the constantly flowing precum into it as she went. She eventually managed to traverse the whole length of the cock in each pump, lathering its entirety with precum for countless more repetitions as its owner moaned carelessly.

The pumping came to an end, however, when Chrysalis pulled away and stood up fully, panting with pleasure as she left her captive dazedly staring at her stallionhood as she whimpered desperately with need. The queen turned around slowly, her slimy cock glistening in the dim light of the cave as it rotated, before finally coming to a gentle stop where it was pointed straight at the mare it was planned to breed with.

“You did... such a good job, Twily,” The changeling spoke between panting breaths. “Now, time for the main event,” She added with resolution before taking hold of her prisoner’s shoulder with a hand and pushing her back with enough force to lay her on her back. Twilight’s lust-induced daze prevented her from closing her thighs to protect her decency, leaving them splayed outwards on top of the still unconscious Cadence.

The over-endowed queen took a look back down at the princess of Love, realizing she had forgotten her, before stepping over her and between the other alicorn’s legs. She next crouched down and grabbed the lilac mare by the waist and lifted her up, staring sensually into her eyes all the while. She hoisted up her captive to place her sex, which she now noticed was sopping wet, over the flare of her shaft and press them together, making the pair sharply inhale and the mare place her hands on her captor’s shoulders.

The changeling and pony then released an abrupt moan as the former’s fat flare entered the latter’s tight sex, only possible due to the ludicrous amount of fluids released between them. The green shaft then kept getting forced deeper and deeper, slowly forcing its way down while both parties moaned vehemently, only pausing at the medial ring. More force was applied to get the ring inside, making a wet popping noise and inciting a sharp moan from the slowly rutted mare.

It wasn’t long before Chrysalis finally hilted within her captive, a pair of light smacking noises being audible from the duo’s hips connecting and a pair of black balls meeting a set of lilac flanks. The changeling took a moment to bask in the sensation before leaning forward enough to have her breasts and lips meet the alicorn’s, softly pressing them together if only to save her strength. She next pulled her hips back slowly, the pair moaning softly into each other’s mouth while their liquids intermingled in the drenched lavender pussy.

The queen paused her motions when only her flare was left inside Twilight, then quickly slammed back in, forcing them to separate as they both released an abrupt moan. Their kissing was quickly resumed, however, now with the princess’ active involvement, and wasn’t released when her captor pulled back and made another forceful thrust.

The thrusting quickly became continuous, a squelching pull backwards, leaving the purple cunt gaping with need, followed by a forceful thrust back in rhythmic motion, inciting a loud moan from the pair. The changeling then wormed a long, serpentine tongue out of her mouth and prodded her captive’s lips, which were separated with minimal resistance, and allowed the tongue to writhe and whip around inside the mare’s mouth. Wet smacking sounds were heard from the interaction, even if overshadowed in volume by the slapping of groins connecting lower down.

Chrysalis begun to speed up her pace, slowly shortening the length pulled back and the duration of each thrust, while loudening the smacks and moans it induced. The submissive alicorn wrapped her arms around her captor and held on tightly as she was violently jostled around from the thrusting, their tits and heads constantly pressed together however, as the pony’s tongue started to move its way out of her own mouth and into her mate’s.

The thrusting reached a fever pitch, the pair constantly moaning with quickly alternating volume as the captor’s shaft got pulled out only to the medial ring before being shoved back in a split-second later. The queen’s balls started bouncing around chaotically, unable to complete a full swing in the duration of each thrust, leaving their smacks into the alicorn’s ass unpredictable in frequency in force. The smacks were, however, often and strong enough to induce more moaning from the pleasurable pain and leave the lilac mare’s flanks sore and red.

The moaning and thrusting took a short lull before one final thrust was made, Chrysalis’s huge cock being absolutely stuffed into Twilight’s gushing pussy, making the pair scream into each other’s mouth with intense carnality. The floodgates were now opened on the massive stallionhood, shooting a multi-liter rope of cum into the princess’ womb, distending it slightly. Another rope tailed the first, and was followed by multiple more, quickly inflating the alicorn’s belly. The volume of each spurt slowly decreased, slowing the rate of inflation, but the pressure of the belly between the mates soon forced them apart while their screams became silent from the lack of air.

More than two minutes passed before the changeling’s orgasm finally died down, leaving her panting heavily while holding an unconscious lilac alicorn with a belly nearly the size of a beach ball by the waist with her cock deeply stuffed within her. She slowly begun to pull the mare off her shaft, a very lewd squelching sound lasting several seconds being made as a result before she finally relieved the battered lavender pussy of its oversized counterpart. Copious fluids were then released from the now-gaping cunt and spilling onto the ground, a puddle being made around the changeling’s hooves.

After multiple seconds of exhaustion, Chrysalis crouched down and set her second broodmare on the ground, standing back up to admire her work. She smirked as she looked at the gigantic cum-filled balloon that was Twilight Sparkle, seeing her belly spilling over her sides and her face perfectly portraying the overwhelming lust and exhaustion she now had.

“Congratulations, Twily,” The queen said amusedly, doing her best nurse imitation, “You’re pregnant with 30 changeling foals.”
