Princess Twilight Sparkle believes she's found a way to change the changelings, to keep them from feeding upon love. What if they fed upon something more willingly given... like lust?

Princess Twilight Sparkle has hatched a brilliant idea. With a recovered egg from the changeling invasion, she plans on altering the changeling inside to change their feeding habits and remove their need to prey upon love. What if they were to feed on something else, something that wouldn't tear families apart and create conflict between the two species? What if they were to feed upon something more readily available and willingly given... like lust?

Insert Pun (and Egg) Here

The faint lamplight cast shadows across the library’s oaken walls, the stars outside barely visible in the glimmering reflection upon the glass. Ponyville’s library was a quiet place of learning during the day; at night, a still and silent fortress, with nopony willing to disturb the peace out of respect and friendship towards the librarian.

Unless that pony was the librarian herself.

“Come on… it will fit…” Twilight Sparkle moaned, sweat dripping from her brow as she ground her crotch against the object between her legs. It was a rough ovoid of mottled green and black about the size of a large apple, and in the lamplight the nectar dripping from Twilight’s marehood made it glisten like an emerald.

Twilight shuddered and bit her lower lip. Disgusting, vulgar, and lewd, her actions should have left her mortified. Part of her was, her flushed cheeks not just red with arousal. But the rest of her didn’t care. She was too caught up in her lust and excitement to worry about how it would look if one of her friends were to burst in unannounced to find her masturbating with a changeling egg.

Changeling. The word was loaded with dark memories of endangered friends and an invasion halted. They were emotional leeches that fed off the love of other creatures, making them into a cross between slaves and cattle. They were a scourge upon Equestria, a threat to the ponies Twilight was dedicated to protecting… and they were living, sentient beings.

“Oh fuck…” hissed Twilight, the folds of her pussy grinding atop the leathery ovum, only the tip fitting inside of her. It was disgusting, to be so aroused as to try and satiate herself with another species’ egg, but it was all for the betterment of ponykind.

The egg had been recovered from Canterlot Castle after the changelings had been banished. It had been Twilight’s idea to try and use magic to alter the unborn changeling within. Instead of love, what if she could alter the changelings to feed upon something less damaging? What if she could guide them down a different path so they could live in harmony with ponies? Wasn’t that a worthwhile goal?

The egg slipped a little deeper into Twilight’s sex, spreading her wide. Her horn flashed with magical energy, another burst of the spell she had developed coursing through her body and into the egg itself, causing it to grow even warmer.

Yes, Twilight had known right away it was the right thing to do, so she could help avoid any more wars between changelings and ponies. But her experiments had been for naught. Changeling physiology left them dependent upon the sort of emotional power that came from love and passion. Weeks of experiments had seemed nothing but a waste of time. It wasn’t until Twilight, awake in her bed, felt the flash of inspiration.

Changelings might need to feed off of a powerful emotion, but the cousin of love was lust, and sexual energy was much more plentiful. At first she had been disgusted at the mere thought and tried to push it away, but the idea had lingered, digging its tendrils into her mind. She’d argued with herself about it, wondering how much different it would be if changelings fed off of sex rather than the more noble love.

Noble. That word had struck a chord. Indeed, the changelings as they were had to manipulate the minds of ponies to steal their love because it was a pure and noble emotion. But what if they only fed from the more common and baser physical lust? Changelings wouldn’t need to hypnotise and control ponies if they were only after sexual release. There were plenty of stallions and lesser mares out there. Ponies without Twilight’s own control over their lower instincts. Ponies that were out having sex and doing… things, instead of staying at home and reading books.

Twilight sucked in a deep breath as she lowered herself down even further, forcing the egg in even farther, and making her moan even louder. Yes, she wasn’t the most experienced mare out there. Even after becoming a princess she’d always found herself more interested in learning and experimenting and hanging out with her friends than looking for a partner.

When she had realized the only way to bring about that change within the egg was to feed it with as much sexual energy as possible, she had almost stumbled and fled. She couldn’t ask another pony to help her, not when she was unsure of what the spells she would have to use might do. It was her responsibility.

She would feed the egg all the sexual energy she could while incubating it, and hope that it would bring about the new changelings she hypothesized.

Her decision had been made the previous night, and the next day she’d set her plan in motion. She gathered up her supplies, sent Spike away for the evening, made sure to close the library early, and that night, after a few drinks of hard cider to lower her inhibitions just enough, Twilight had begun.

“This feels so strange,” she told no one as she pushed up and down on the egg as if it were some squat phallus. Her pussy resisted, straining against the girth of the object, but even then it still managed to shoot streams of pleasure up her spine. “I can’t believe those herbs Zecora gave me work so well,” she added, glancing over at the bottle of cider on the nearby table. Whatever had been in the mixture, Twilight could feel the way it worked over her system, making every sensation more sublime and lighting the fire beneath her own lust. She didn’t just want to feed the egg with magic and sexual energy – she wanted to fuck it.

She shivered at the crude word. “Yesss… I’m fucking this egg. I’m fucking a changeling, and it feels fantastic!”

Twilight sent another burst of energy through herself and into the egg, bathing the egg in the same waves of pleasure she was feeling. She could tell it was responding, the egg growing warm and pulsating back against her movements. It might have been the most embarrassing way to incubate an egg, but Twilight was beyond caring about such things as her hips crew even closer to the floor. She’d only planned on masturbating with the egg, using it to get herself off so she could feed it as much lust as possible, but as she looked down at herself and the way her folds were spread apart by the egg, the plan dissolved away.

She licked her lips. “I want you inside me,” she said, her thoughts clouded with lust. She timed her thrusts with another burst of magic and let out a happy moan as she stretched a little further. So close! she mentally shouted, her body burning up. She didn’t care that the egg seemed to be almost glowing with energy, that tendrils of her own lust were sliding back up her nerves, the egg instinctively coaxing more sustenance out of Twilight. She wanted that egg to fuck her. It was huge and foreign and dangerous and Celestia damn it she wanted to feel it inside her.

Shouting like a banshee, Twilight pulled up before slamming herself down, her ass slapping against the wooden floor as the resistance finally broke and, with a wet pop, the egg pushed up into her cunt in a single motion.

The orgasm was excruciatingly pleasurable. Twilight’s body twitched and jerked as bliss overcame her. Her insides were stretched out, the fullness of the egg so awkward and yet so wonderfully satisfying. Her nectar squirted out over the floor as she sat there, moaning and mumbling and rubbing her belly, feeling the firm pressure of the egg beneath her flesh. Part of her was worried, feeling the egg shifting as if it were moving even deeper, but that only sent her into another loop of orgasm after orgasm. For one endless moment, Twilight was lost to sexual gratification like never before.

She didn’t know how long it took before she regained control of her senses, only to find that the whole world had been turned sideways.

“Oh wow…” she mumbled as she sat up, having toppled over when she passed out. Her body was aching and sore and smelled of sex and sweat. Still, she couldn’t keep a slightly embarrassed grin from her face. “I can’t believe science could feel that good. I bet the egg has had one heck of a meal.” Shaking her head to clear some of the cobwebs, she rose up onto unsteady hooves, biting her lip at the few bursts of pleasure that accompanied it. Zecora’s herbs are still in my system, she realized. Twilight couldn’t complain – it had felt so good that she looked forward to giving the egg another feeding, making sure to keep it bathed in as much sexual energy as possible.

Still feeling slightly drunk on lust, Twilight turned around to locate the egg and start round two. Her smile vanished as she stared dumbly down at the puddle of her own juices on the floor. “Where’s the egg?” she asked as she glanced around, afraid that she might have knocked it aside when she had passed out and–

There was a pressure inside Twilight’s stomach that caused her legs to stiffen. She hissed sharply, the sensation both disorientating and incredibly erotic. Blinking away the stars in her vision she looked beneath herself… and found her belly bulging out noticeably.

She gave a nervous laugh. “Oh. It’s, ah, s-still inside me.” She was amazed she’d managed to fit the egg inside her body, but then blushed as she remembered just how horny she’d been. Her horn began to glow with magic. “Okay, time to get you out of there.”

She sent the tendrils of magic into her dripping snatch, doing her best to ignore the pleasurable tingle of the energy against her puffy lips, and grabbed both the eggs in her spell so she could… could…

Twilight’s eyes opened wide, and she swiftly did another count. “Oh no. No no no,” she whispered. “This… this isn’t good. Why are there two eggs? There should only be one!” Tightening her aetherial grip Twilight tugged on the first egg, but was only able to move it a few centimeters before it bumped against something that almost sent Twilight to her knees. Her expression darkened. Casting a spell over herself, Twilight found her fears were confirmed.

Both eggs were inside her womb.

The question of how reverberated around inside Twilight’s head, doing nothing to calm her sense of panic. “There has to be a spell I can use! Something to fix this.” She moved as quickly as she could to the nearby stack of books, each step causing a tingle of pleasure to emanate from the bulge in her stomach.

Books, scrolls, and pages were tossed aside as she dug through the assembled information, her desperate eyes pouring through it all at a rapid speed. There was another twitch in her stomach. “How could I be so foolish as to get a changeling egg stuck inside me?” she asked the stacks of paper. There was no response. She grimaced, pushing aside the embers of burning lust lingering in her loins. “There has to be a reason as to why it’s split into two. It shouldn’t be possible. It’s been in hibernation for years. Even if it was fed a lifetime of love it couldn’t…”

A cold shiver worked its way up her spine as she froze in place. “No…” she murmurred. “No, it couldn’t be. Could it? Even with Zecora’s herbs, one pony’s lust couldn’t be enough sustenance to make the egg split to absorb it all. Lust can’t be more powerful than love.”

She shook her head. “Okay, I can’t be sure what effect trying to change a changeling’s diet has on how it handles energy. I will have to do more experiments. But that will wait until after they’re out of me. I’ll just have to keep my desires in check until…” Twilight’s eyes opened wider when she realized one of her hooves was between her legs, rubbing at her dripping cunt. She jerked it away as if she’d touched a hot stove. There was a moment of regret that only deepened her concerns, her hips quivering as more of her nectar dribbled down her legs. “I have to keep focused. I can control myself. I can… can…”

A low moan escaped Twilight’s lips as her pussy grasped at nothing, desperate for more stimulation. Her knees went weak and for a moment Twilight’s thoughts were consumed with her desire to feel more. Amidst the storm of sexual hunger, there was another surge of warmth deep within her core, an increased pressure behind her sex, as her belly pushed out a little further.

She stumbled to her side and slammed into a table, grasping at it to keep from falling to the floor. Twilight’s wings hugged her belly. She didn’t need magic to tell her what had happened, but it still seemed impossible. “The eggs… t-they divided again…” she panted with a mixture of disbelief and excitement. She couldn’t help it. As she ran her feathers across her sensitive stomach her tail hiked up higher, a natural response to her lewd hunger.

It felt amazing. Beneath the fear and uncertainty and the small part of her shouting about how dangerous it was, Twilight had never felt so horny in her life. There was no resistance when her hoof returned to her crotch, her panting growing louder as she began to roughly play with her dripping snatch.

“Oh fuck, I n-need to just… just work off some of this lust. If I c-can get off, I will be able to think straight,” she told herself as her horn burst into life once again. She gave herself another quick scan. Her hypothesis was correct: there were now four of the cantaloupe-sized eggs crowded together within her womb. They almost pulsed with all the energy they’d absorbed, reflecting that lust back into Twilight’s system, feeding her own desires. It was a positive feedback loop – the herbs in Twilight’s system kept her aroused, the eggs feeding off that lust until they could absorb no more and they split apart, the excess lust leaking out of them back into Twilight’s sensitive loins, keeping Twilight and her herbal-augmented desires at a heightened state of arousal.

But the reason why grew less and less important as Twilight’s hoof glistened with her need. It didn’t matter that she was acting like an addict, that she was losing control of her own body, that her hunger for sexual release was pushing aside her rational mind. With her wings massaging her swollen gut, Twilight’s horn shifted its magical grasp back to her rear, teasing her dripping pussy with purple energy that formed into a clearly phallic shape.

“Oh yes! Fuck me!” groaned the alicorn as she pushed the aetherial dildo into her warm cunny, savoring the way it spread her apart. Thoughts of a few of the cuter stallions from around Ponyville flashed through her mind – with the image of Applejack’s brother lingering for a few delicious moments – as she forced the magical toy a little deeper. Despite her inexperience, her body knew what she craved, and she almost bit her lip when it drilled into her. She’d never been with a stallion, she’d never been much for flirting or trying to ‘get lucky’, but at that moment she would have lifted her tail for any stallion that would have walked in through the library’s doors. “Fuck me fuck me fuck meeeeeaaaahhh!”

Her lewd cries reached a new crescendo when there was a burst of warmth in her belly before it surged out once again, pushing outwards like she had become instantly pregnant. The pressure was incredible, enough to drive her to the very edge of an orgasm. “T-They divided again,” she moaned, wings caressing her stomach. It was incredible. Every time they doubled in number, giving her the look of a mare halfway through a pregnancy. The amount of sexual energy she had to be producing must have been incredible to feed such exponential growth. She was helping to single-handedly breed a new form of changeling that would remove the conflict between both species. She was going to create a new harmony for Equestria… and it felt amazing.

She gasped when her magical sex toy split into two, the second half slipping beneath her tail and sliding into her ass with barely a moment's resistance. What would have horrified and embarrassed her hours before was nothing but another source of pleasure to her lust-addled mind. Standing in the middle of the library, legs spread wide, wings gripping her stomach, two hazy dildos plunging into both of her eager holes, and a womb full of new life, Twilight felt a sense of satisfaction and purpose that she’d never felt before. She was bringing forth new life. She would be a mother to a new form of changeling. She was fulfilling the role of a changeling queen!

It was too much for Twilight, and as another orgasm crashed over her like a wave breaking through a levee her knees finally gave out and she collapsed onto the floor.

Or she would have, if the sudden burst of growth within her belly hadn’t kept her up off the floor, her entire weight supported atop the egg-swollen stomach that left her looking like she were overdue to deliver a foal. The pressure was almost as pleasurable as the sensation of having her loins stuffed with magical cock. Her hooves barely touched the floor, leaving Twilight nearly immobile. She felt like an old fertility idol in a museum, a gravid goddess worshipped by early pony societies, and she couldn’t imagine ever going back.

The arcane phalluses resumed their thrusting. “Yessss,” she hissed. “Fuck your queen. Breed her. Fill her with more eggs!” Twilight’s body responded eagerly to the resumed motions, her nerves once again burning with desire. There were at least sixteen of the eggs inside her womb, straining her flesh with their sheer mass and leaving her skin pulled taut around them. She was certain it was some side-effect of the magic and its interaction with the eggs to allow her to still be alive after their growth. It should have been impossible, to become so big so quickly.

But as Twilight gazed down at herself with hungry eyes, she only wanted one thing. “Breed your queen even larger! Give her even more eggs! I am going to make a new hive all on my own… My hatchlings will not steal love but give ponies pleasure! They will satisfy the lusts of any pony, giving them nothing but physical joy so they might feed! And I… I will be the source of them all, the creator of a new Golden Age for ponies and changelings, and I will be massive! Huge! I n-need even more! More! MORE!”

When Twilight screamed again her mind was almost wiped blank by the explosion of pleasure from deep inside her core. Twilight rose up into the air, her hooves leaving the ground as her stomach was forced outwards by another splitting of the eggs, doubling the size of her stomach in just a few short seconds. Her belly was enormous, a mammoth sphere of egg-filled pony flesh that looked obscenely distended beneath the small alicorn riding atop it all, but there was no hesitation in Twilight’s expression.

Her horn continued to glow as her summoned dildos continued to piston in and out of her holes, feeding her lust, keeping her on edge. The sexual energy within her was enough to ensure there would be many eggs created tonight. Dozens. Hundreds. Enough to found a full hive. She had a whole night ahead of her before any of her friends might discover her, but by then there would be no stopping what she had begun.

She would grow and grow until she was impossibly pregnant, and then she would give birth to a new race. Twilight licked her lips as she felt the warm pressure rise even higher, signaling the imminent arrival of another division of her eggs. She would become some egg-filled thing, dedicated to breeding… and she looked forward to every last minute of it.
