I felt a twinge of nervousness roll through me as I was just asked by this lavender mare named Twilight to breed her, 'to give her my grubs', feeling her squirming beneath my hoof, the palpable love and lust flowing from her only affirming just how real this situation was. As I looked at her clit winking at me, I found it oddly attractive, knowing that this is how mares ask their stallions to breed them, or to instinctively show their interest in them or their pleasure to their stallion, from my lessons on pony behavior. "Um...it looks like you really do want to breed," I said, getting a series of sharp nods from her; "but...uh...I can't actually give you grubs. That's not how changeling reproduction works."

Twilight seemed to deflate a bit at that news, but quickly recovered herself to save face. "O-oh, did I say that out loud?" she asked me, following it with a few forced chuckles and ended with a sighed 'hooooo', a blush burning hot on her face, "Ohhhh dear."

I simply blinked and stared blankly, holding a poker face. I literally had no idea how to react.

"I, uh, well...I've always been curious about having sex with a changeling, OK?!" Twilight stammered, doing her best to explain what she'd asked of me; "I went into heat shortly after the invasion and I started thinking 'I wonder how changelings reproduce?', so I started imagining all the possible ways, and possible appearance of a changeling's penis, while, um, 'quelling the heat' so to say."

"So you masturbated to the thoughts of a changeling filling you with their grubs." I deadpanned.

Twilight gave a quiet gasp, her deep blush making her once-lavender face nearly the color of a red rose, not daring to respond as she looked away in her embarrassment.

"Well, sorry to say, but that is incorrect on so many levels..." I said, as even on the verge of mating her, I thought I should set some things right. "Firstly, I'm a worker drone changeling, and as such I can't interbreed with other species without a certain pheramone that only breeder drones have. Secondly, you'd need to be implanted with a Queen's eggs to be impregnated by me since I'm not a breeder drone, otherwise it's impossible. Thirdly, I'm a pure male, so I can't even produce eggs. If I were a hermaphrodite drone, that would be different. Fourthly—"

"Can we just buck already?" Twilight deadpanned as she clearly shed her embarrassment to make room for her lust, then shifted on the bed so she was laying on her chest, spread her legs wide and raising her rump up, giving a quiet whimper of anticipation as she put herself into the 'leap-pony' position. "I-I don't care about the facts right now! I just need you to breed me! Now!"

Sighing, realizing that she really must want to live out her fantasy and with my dick starting to hurt from being so hard for so long without any stimulation, I then rolled over onto her proffered back and mounted her, lowering my body so that it's aligned with her marehood, my hooves on either side of her and my chest against her back. I then started to prod against her until I found her entrance and gave her withers a light kiss, smiling with half-lidded eyes as I felt her now-hot, swollen entrance against my tip after some number of seconds missing and rubbing my lube all over her flank instead.

"Sorry, I've...never done this before." I muttered, before feeling a shudder from her.

"You're...a virgin? I'm your first?"

"Y, yes."

She shuddered harder.

"Are you OK? Can I proceed?" I asked, then heard her gasp slightly as I finally prodded against her slit, as though asking permission to enter her. She was not amused with my hesitance.

"You're not supposed to ask! You're a fearsome changeling! You're a scary predator who wants to gobble up all of my love and rape me pregnant with your young!" I heard her say with a hint of annoyance, as though I were interrupting a particular fantasy of hers, with her moving her hips to rub her wet lips against my knot; "I want you to breed me, and I don't want you to be gentle. Have your way with me you beast! Impregnate me!"

"Uh...ok? If that's what you want...even if that's impossible..." I said questioningly, somewhat off-put by what she'd asked and what she was calling me regardless of the reality of the matter, but nonetheless choosing to comply. No reason not to after all, given this was what we both wanted, even if this was pretty weird in context. I grunted as I pushed my smooth tip into her, finding it a bit difficult to push in due to my angle but learning that it, in turn, made her a tight fit. It surely helped when she rose her rump a bit, with that instead letting me then slide smoothly and more deeply into her instead of having to force it in.

Slowly but surely, I felt my shaft disappear into her, my mind awash in the sensations of taking my first mate. Everything felt so wet and warm and slippery, and I kept pushing in until I felt my ridges one-by-one popping into her, each one being welcomed in and earning a quiet gasp and internal squeeze from her, a light twitch coming from my penis with each burst of sensation it gave me. At last, my partially-swollen knot pressed against her lips, marking my stop.

I was up to my knot inside a mare.

A real, love-and-lust-gushing pony mare.

A mare who was a PRINCESS OF EQUESTRIA!

It felt amazing!

We both held still as I adjusted to the feeling of her warm, ribbed passage squeezing and rippling gently around me, a particularly tight spot just a bit inside her entrance occasionally squeezing between two of my rings tightly and making me gasp, past that tightness even softer than her entrance. Her body was clearly getting used to me as well.

I looked back at her belly, a seemingly-innocent, gentle curve hiding what was going on inside; hiding that my pointed tip was somewhere deep in there, deep inside her royal passage. Despite my instincts telling me to enter her fully I left my knot outside of her for now, knowing what would happen if I did put it in her; that that would make this be one short mating session if I'd knotted her already.

~ ~ ~

I moaned as I felt him enter me, my passage instinctively working to bring him deeper inside me as soon as he penetrated, my belly burning hot as though I were in heat, my mind clouded with the need to have a stallion filling me up; my breeding instincts going full throttle it would seem. I loved how his penis slowly spread me instead of so sharply prying me open at once like a stallion's flare would have, the gradual parting sensation from his tapered penis being something I definitely preferred "Oooooh Celestia..." I cooed out, my head pressing back into the mattress as I felt myself being spread, giving a quiet cry as each of his rings popped into me and slid deeper, each one grazing my clit. I finally felt him 'bottom out' in me some moments later, feeling the large bulge at the base staying outside of me as he then stayed still.

As he remained unmoving inside me, me feeling each pulse his length made in me and throb of his heartbeat through it, I bent down and kissed him on the lips again as his head was resting beside me, realizing his body was the same temperature as a pony's now instead of colder like it was before, his stallionhood indeed feeling quite hot inside me. "Is my little changeling feeling better...n-now that he's stolen most of my love...?" I asked softly after breaking the kiss, looking over and giving a wink to let him know I was just acting, gently grinding my lower lips against his knot.

"Uh...yeah. I feel much better Twilight. Everything feels soooo much better than before and...who would have known sex would feel so...so amazing..." he said, with me, and undoubtedly him as well, enjoying the sensation my grinding brought; feeling his whole length undulating around inside of me, a feeling I hadn't felt in far too long it would seem. I continued doing it for a while before feeling him shift, then starting to pull out and push back in, feeling him slowly starting to jerkily hump into me.

"S-start slow now." I warned for his sake, breaking the character of the helpless rape victim for a moment to help him ease into his first time. I heard him let out soft pants through his nose as he did as told, every slow push and pull bringing a surge of delight through my body as I felt his rings rubbing over my clit as each popped into or out of me. I then had a realization at what he'd earlier said. "I-Is this really your first time?" I asked, and felt another thrill go up my spine as he nodded. I'd just taken his virginity. I'd just taken a stallion's virginity.

"O-oh, Twilight, this feels so good...!" I heard him whisper, his hips now rolling at a more rhythmic, natural pace. Apparently, he'd let his instincts take over and the motions of his hips smoothened out as a result, letting him slide easily into and out of my well-lubed body now.

I moaned as I felt him start to hump into me slowly, and surprisingly gently too. Too gently. I felt his tapered shaft spreading me further with each entry, every time he hilted in me making his knot press against my clit and sending a massive tingling wave of pleasure through me, with him feeling so BIG inside me. His cock had swollen a bit more since he'd entered me, now easily quite above average among pony stallions in length but somewhat thinner in width until half-down his shaft, though it still felt absolutely huge to me given my general inexperience. "H-harder..." I demanded, and felt him comply; "I told you to have your way with me, changeling! Breed me! C-Claim me as your broodling!"

Given that demand, I felt him ram into me hard, growing more bold and tapping against what must have been my cervix each time with his very-thin tip as he went so much deeper into me, even feeling the tip starting to slightly spread the entrance to my deepest sanctum each time he 'hilted' me. I questioned how such a thing was possible, with a mare being out of heat usually leaving the cervix sealed tightly, with the only time the cervix relaxed some being when a mare was in estrus, fertile...but my Spring cycle was over two weeks away still...

"Oh by the Moon, y-you beast! " I stammered, only to cut myself off with a deep moan, feeling his thicker base rubbing my clit again, earning my clit winking and giving it a kiss as he once more tapped my deepest barrier with his thin glans. "Y-You're going to claim my womb too, aren't you?!"

~ ~ ~

Throughout my life, I had never experienced much love, indeed getting none past what I absolutely required to survive even while living in the hive and not even that in Ponyville. Most of the love we captured through the infiltrators – whom transformed into love ones to capture love through affectionate gestures or, if possible and most desired, sex – was given to the Queen to help her produce her eggs more efficiently, the breeding drones, or chosen worker drones, to produce their sperm, or the incubator mares to keep the implanted eggs healthy; but now I was receiving it directly from a pony, at a seamless and plentiful source, and what an experience it was. The pleasure of mating, the source of such abundant love, of plunging myself knot-deep within her with each hard thrust, only made it that much better.

As I heard the generous mare moaning as well as feeling her softly kneading me inside her, I smiled. "I'm glad you like this as well, Twilight..." I said softly, before closing my eyes tightly and starting to speed up a little, increasing the emotions transferred from her while also just generally making it feel better for both of us at the same time.

With every push I felt my tip hit a very tight ring deep inside her body, stopping me from going any further. I took this as a challenge, trying to fit more of my length into her, though my knot quickly stunted my progress...but not before I'd entered my tip just into it. Realizing how this might be painful for this mare somehow, despite it feeling so instinctively right to me, I pulled out part-way, scared I had hurt my benefactor somehow as she was silent now, quivering lightly. "Twilight, are you alright?" I asked, panicking a little. If I had hurt her, she might tell me to get off her. To leave and not come back...

When I suddenly stopped and pulled back, I heard her whine slightly in what seemed to be disappointment. As I asked if she was alright, she gave a huff. "You're not supposed to be concerned about me or care about me at all, remember? You're the big, mean changeling trying to steal all my love and fill me full of your babies against my will!" Twilight said, her voice deepened by her pleasure, "You better rut me and take all my love...then claim my womb for your grubs! Now!"

I sighed internally, but complied. Who was I to deny a mare her pleasure or myself more food and pleasure, even if this mare did have some really weird fetishes?

~ ~ ~

"W-wait, let me just..." I said, before suddenly levitating him partially off of me as I got an idea, leaving him still deeply penetrated in me in the process. I turned around so I laid on my back, both of us moaning out as his cock rotated deliciously inside of me, sending tingles up my back at the unusual sensation. As I laid him back down atop me, his back hooves were now off of the bed and planted on the floor; my rear was on the very edge, with him leaning over me once more as I laid on my back, our chests pressed together. "There. Let's try this position now."

As he nodded and resumed his thrusts, I moaned deeply as I felt him getting rougher with me; feeling my walls trying to clamp around his length as this position let him go even deeper. There was also a slight amount of pain as his very tip entered my cervix each time, the first time I'd ever been probed so deeply, but that pain was easily overwritten by the feeling of utter fullness and stimulation the rest of him was providing. Once more I had a moment of clarity, realizing that him entering my cervix shouldn't be possible given I wasn't in heat yet, but that was washed away by a huge surge of pleasure, making me clench down on him and moan deeply. Besides, he couldn't very well fill my womb with his grubs like I so wanted if he didn't even get into it.

I felt as he complied with my earlier request, returning to the previous, rougher speed he was at and progressively increasing it, his own urges to climax apparently kicking in stronger. I could feel his once-rhythmic movements becoming more erratic and unpredictable, his penis throbbing and swelling in me, knowing what that meant. I'd read enough biology books to know the universal signs of a male climax, regardless of species.

I felt my second orgasm building, the burning in my pelvis increasing more and more as he continued to thrust into me, my contractions now growing more rhythmic. "I'm...so close..." I whispered out, before suddenly slamming my hips back towards what was so pleasing me as I moaned deeply, my body trembling as my back legs wrapped around his haunches and roughly forced his hips against mine - and felt a very intense stretching at my entrance in the process; "...you better not pull out of me when you cum-MMMMMMMMMM!"

~ ~ ~

I could feel the same tight, burning sensation in my pelvis that nearly burst from before when Twilight was sucking on me, my once-rhythmic movements becoming more desperate and rough as my pleasure grew and that sensation of having to pee swiftly approached again.

"I'm...so close..." she whispered out, before she suddenly slammed her hips up to mine and moaned, trembling as I felt her legs wrap around my rump - then roughly forced me forward, unintentionally forcing me to knot her in the process, "...you better not pull out of me when you cum-MMMMMMMMMM!"

Then I realized what had just happened. "Oh b-buck! I-I-I-c-can't – I can't p-pull out! Y-you knotted ussssss~!" I hissed out in my state, the incredibly TIGHT vise of her passage overwhelming my senses for a moment.

"OH BUUUUUCK!" I heard her squeal out as she clearly felt me spreading her entrance entirely with my engorged knot, with me in turn feeling that massive SQUEEZING of her passage when my hugely swollen knot entered her all at once, feeling my pleasure exploding higher than ever before. My body nearly shut down as I felt my sensitive knot captured so tightly inside the warmth of another for its first time ever, feeling my tip also penetrating that deepest, tight ring at the same moment and adding those sensations to it all as well, my instincts burning hot at that ultra-tight squeezing on my tip. I'd just entered her deepest cove, bypassing that inmost barrier to the womb that my Changeling teacher had called a cervix, 'the mouth to a mare's uterus'.

*I, a paltry, practically-pathetic peasant of a pseudo-pony, past prudence, was packed and pounding, plunging and pumping my perky, palpating phallus profusely into this pink-and-purple pony's proffered posterior. Her powerfully pulsating, pouting, perfectly-puffy peach and peaking, practically pinching procreation-passage – princess pussy, put plainly – pulled my penis with pure passion.

Personally, passing any perception of pause, I pleasantly pistoned, pat-pat-pat, rapping her rump rather roughly, rueing it not, rhythmically ramming her regal rear with my remarkably real, rare, riveting and robust rutting-rod, removing it and refilling the rebellious ruler in recompensation for romance - reasonably respectfully really, rather reproaching and repulsing rapaciousness.

I, the royal's roomie, rocking my red rocket – rather, not rouge in realism – then ravaged rapturously, rolling and relaxing repeatedly, really reaming the royalty's rounded, ruddy, reddened ravine, rapidly rearing rudimentary reproductive realisms, rather than reasonabilities, as the righteous, realistic rules of this room. Reproductive or recreational? Recondite; obscure. Orgasmic? Overtly.*

I was in her womb. Her cervix was squeezing my tip. I was in nirvana.

I stopped moving, feeling as though I could burst at any moment, my penis throbbing rapidly. After my brief pause, I was again quickly and deeply trying to thrust my hips even as I could not move within her, my instincts not letting me hold back anything anymore now that I was fully inside my mate and trapped inside of her until I'd seeded her, my hard throbs telling me I was very close now that I had her knotted.

Feeling her body milking me hard, like I'd heard a female changeling drone or the Queen would do throughout the entire mating, my hips still humped against her fruitlessly while being tied to her, feeling her passage grow tighter around me as my knot and penis swelled up even further, her walls growing tighter still. I paused a few moments to simply take in the amazing feeling of just how tight the fit was, her walls clamping down so deliciously tight on my entire length, especially on my knot. I struggled to move as my knot was literally impossible to pull out at this point, and would no doubt only be painful if I just forcefully tried to do so – so I decide to just stay in, trying to penetrate her further and get deeper into her womb on instinct, trying to stimulate myself more to end the pressure in my pelvis. Something deep inside of me told me thrusting more was the only way to end it, and end it I would.

I tried my best to hold on, to enjoy this mind-numbing pleasure for a few seconds more, but it was all too much; her body's kneading me for my sperm was getting to me, and her constant moaning and shivering body were certainly not helping. "Twilight, I'm going to e-ejaculate soon!" I warned again as I felt her clenches become more forceful and grow rhythmic, hearing her squeal as she suddenly grew tighter than before and apparently came again. I continued to thrust faster, futile as it was, trying to bring myself to my own finish as I felt myself now in her very core; her womb.

"OH NO, I'M TRAPPED WITH YOU INSIDE MY WOMB NOW, WHATEVER SHALL I DO?! I GUESS YOU'LL HAVE TO C-CUM IN ME Y-YOU MONSTER! C-claim my body for your s-squirmiiiiing, wriggling g-grubs! Make my uterus s-swell with your young!"

~ ~ ~

As his knot forced into me, spreading me far and beyond wide, I came. Hard.

I couldn't really breathe as I felt him somehow penetrate me even deeper, feeling this changeling now in what must have been my womb. I felt my inmost chamber massaging his tip, my whole body trying to coax him of his seed, a passive nagging prodding me, making me wonder how my cervix being so pliable and spreading like this was possible with me still out of my estrus. In my most intense orgasm ever, however, I simply couldn't care. "OH NO, I'M TRAPPED WITH YOU INSIDE MY WOMB NOW, WHATEVER SHALL I DO?! I GUESS YOU'LL HAVE TO C-CUM IN ME Y-YOU MONSTER! C-claim my body for your s-squirmiiiiing, wriggling g-grubs! Make my uterus s-swell with your young!" I squealed out in my over-stimulated state, my deepest desire put to words, my front hooves joining my rear ones in roughly squeezing his whole body as tightly to mine as possible as my passage milked his trapped member, embracing him tightly in this moment of climax.

"L-Like I said earlier, that's..." he stammered out, but I gave another tight squeeze on his cock to interrupt him, making his statement end in a quiet squeal from him. Even as he was knotted and swollen deep inside of me, in my very womb, he tried to lecture me!

"JUST SHUT THE BUCK UP AND CUM ALREADY! KNOCK ME UP!" I screamed out, anticipating the inevitable feeling of his seed coating my most sacred, now-violated chamber and giving me his wriggling mass of hundreds of changeling grubs against my will; to complete my fantasy of being forcibly impregnated by a changeling, even if I knew in reality I wouldn't really get pregnant.

"Alright, you asked for it!" he said and apparently stopped holding back, letting his member pulse harshly a few times before I actually felt the first shot of his load traveling up his length and making it swell a little thicker, the hot liquid clearly felt traveling up his underside, bulging each inch it traveled along the base.

"Here it...I...cu-cum!"

~ ~ ~

I was totally awash with bliss as I felt my first blast of cum into her deepest depths; her milking each and every glob of my life savings of seed into her womb and me gladly depositing each gush. My cock kept pumping and pumping, us staying stark still save the occasional quiver as she kept her inner muscles working on me, milking me of my seed, both of us silent and still except our shuddering breaths. I couldn't even be mad she called me a monster at this point. She just felt too good clenching down on my penis as I...'came'?

Some time later, I felt as my main climax tapered off after multiple huge streams of my virile seed gushed into her and a state of lesser arousal and satisfaction replaced it, my more-swollen length pulsing with each much-smaller squirt, my knot keeping any that would leak out of her womb and into her passage inside of her until I deflated in some minutes. As an added bonus, it was keeping her locked to me so I could absorb more of the now-excessive love from her through the extremely intimate contact. She didn't seem to mind.

I simply laid there in bliss, getting a small spike of pleasure each time I'd throb and squirt another, much smaller spray of my seed into her, her legs' grip on me now slack and trembling occasionally and the expression on her face one of pure satisfaction.

After some more moments of me filling her womb, my knot trapped within her as she squirmed her hips near-constantly, she suddenly tensed up and cried out again, her passage eagerly squeezing over my entirety again and seemingly trying to claim every drop of my seed into herself. More of her orgasmic fluids splashing over my crotch as she apparently came again and squeezed me tightly to her body, apparently overtaken by the sensations of me constantly stretching, pulsing, and squirting into her, as well as my full weight upon her and holding her down as I pumped her full; clearly making her feel pinned down by a predator like she wanted. I felt like this was what my whole life had led up to, a deep satisfaction as I completed what I felt I was born to do. My life's purpose felt like it was to breed this mare. "M-make me...your...b-broodling..." I heard her stammer out, then mumble something else out after, my body complying to her demand with another long, heavy stream of cum into her depths.

Even still, as we came together, I could hear the subtle scratching of quill on parchment over her impassioned cries, moans, and whinnies.

~ ~ ~

When I felt my passage strained to its limits as his knot swelled huge in me and that very thick, slimy warmth start squirting directly into my core, my scream escalated a tone and merged into a whinny; a second orgasm already rocking through me as my whole tract was stretched so wide, his deep gushes of extremely thick, sticky Changeling semen never seeming to end. It felt so satisfying, like I was being given a hug from the inside as I felt him pulsing and pumping into me, the sensation something that I could only compare to being comforted in the most intimate way possible. Never before had I felt so deeply, instinctively satisfied, like this was what I was always meant to do, like I was always meant to carry a stallion's young.

I clung to him as my only anchor in this sea of bliss and never thought the waves of the most extreme pleasure I'd ever felt would stop, leaving me a trembling, whining mess beneath this changeling as he planted his seed, his babies, within my uterus. "M-make me...your...b-broodling...I...I love you..."

I could only lay there and remain pinned beneath him for the next Celestia-knows-how-long, feeling myself cum again and again, feeling him continue to pump his seed into me - each throb and burst of Changeling cum inside of me sending my pleasure up a notch, the growing heat of his expanding mass of virile semen in my belly making my breath become forced as I imagined I was being impregnated by it...and his cum never seemed to end! I noticed that as I was filled, my belly gently swollen now as his seed had nowhere to go but be forced into my womb and slowly stretch it out, that the intense burning that had started when we'd entered my chamber, the one akin to my estrus, had ended as he'd inseminated me. Interesting. I wrote a note of that.

Though, all good things must end, even a changeling's massive first orgasm. As he pulled out of me after ten minutes of near-constant bliss later, it hurting a bit as that still-huge mass of a knot is pulled from me, I finally felt my passage slow its clenching and my seemingly endless chain of orgasms end.

When I could, I shakily lifted my head enough to look down at his still-huge knot, hardly believing that orange-sized thing was even bigger before when it was still inside of me, feeling and watching a small flood of his slightly-green-tinted-pearlescent cum streaming over my ponut and into into my tail. "Holy hay, that was the best sex I've ever had..." I said weakly as I laid there panting, hearing his own labored breathing in kind. "...and the biggest load of sperm I've ever taken. T-Thanks for...for knocking me up with billions of your grubs..."

I heard him give a huff. "It felt great for me too and thank you, but..."

I used my magic on his muzzle before he could continue his earlier sermon about how it wasn't possible, instantly shutting him up, but followed it with a brief kiss. "Just shut the buck up and kiss me, sire to my future grubs..." I said before locking my lips with his, letting my tongue trace over his sharp fangs and reminding me he truly was a predator in some ways. Oh yeah, this couldn't be the last time THIS happened. No bucking way.

"Wanna 'rape me' again and give me more grubs? I want a whole Changeling hive of my own!"**

Author's Note

Twilight, you're a really kinky mare.

* - I really can't say I'm sorry for this patch of purple prose. I regret none of it. At all. Also writing this portion made me giggle. Hard.

**- This either. I'm not sorry.
