Cadence quickly felt her forelegs buckle under her as the pain burnt straight through her rear, causing the mare to fall forward and push her muzzle straight onto her crumpled appendages, muffling her surprised and agonized scream.

As she struggled to overcome the sensation of something foreign and very big occupying the space in her rectum, Cadence tossed her mane to one side of her muzzle so she could look back up at Twilight Sparkle that grinned mischievously back at her.

“Y-you asked for it…” Twilight responded with a huff. “Oh wow, it’s so tight in there…”

“G-g-get it out!” Cadence winced, her wings spread wide and completely locked at the hinges. “AH! Pull it out! Pull. It. Out!”

“Nope.” Twilight responded monotonously, her grin menacing. “How do I sound now, hmm?” She bucked her hips forward until the full shaft forced its way down to the hilt. “Teasing me earlier; saying you changed my diapers... trying to embarrass me… well,” leaning over her fully, Twilight whispered into Cadence’s twitching left ear. “... who’s being the little filly now, hmm? Whining because of a little pain… you want it really, don’t you?”

“Puh-laaaeaase-ahnnn!” Cadence’s words trailed off into a gibberish mess as she felt her anus squeeze around the intrusive phallic shape, failing miserable to prevent its full penetration.

With wide eyes, Cadence pushed her muzzle against the ground, trying her best to will herself forward and remove her impaled rear from upon Twilight’s cock and yet despite the unusual, burning pain she was assaulted with, she could barely move.

Her rear screamed out in agony and yet her sex-fueled brain ashamedly wanted more. It was a conflict ion Cadence found herself oddly thrilled by; a humiliation that some pony would be willing to fuck inside such a dirty place… and Twilight’s words? It left little to the imagination.

Twilight shuddered as she began to work hips and slip herself in and out of Cadence’s constricting anus. “It’s kind of dry in there though…” Twilight groaned. “B-but it feels great… no, better than great… it’s so tight I can… Ugn, I can feel myself ready to cum inside of you already... can you stop squeezing so hard?”

Cadence gnawed on her lower lip as she grunted against Twilight’s slow yet thunderous thrusts. Every stroke shook her to her very core. Her entire body was rigid from the assault; her wings remained erect and ached under the strain; her neck stiff from the awkward angle her head had tilted to.

“C-cum,” Tears streamed down her muzzle, her voice pleading for it to all end, “please—ah! Please! I can’t… I can’t take this pain any more.” She almost wept her plea, but Cadence could not help but release an all too pleasing moan when she felt Twilight pull out her dick’s bulbous head from her gaping, sore anus.

Before she had time to recover from the odd sensation of the cool air occupying the space that her newly stretched anus had exposed, Cadence’s breath hitched in her throat when she heard Twilight’s desperate groan and for her final thrust.

This time, the entry was wet.

So very wet in fact, it was quite unnatural.

In fact, something warm and comforting had started to fill up inside of her and just as Cadence realized just what it was, she looked back at Twilight, whose face was contorted into something she could only describe as a blissful agony.

The younger Princess’s mouth was agape and her tongue was lolling out of one side, drooling with saliva as her eyes rolled back into her head. The wondrous noise that Twilight released was something Cadence had never heard before. A grunting moan that almost mirrored something that Shining Armor would make whenever Cadence sucked him off.

Music to her ears, Cadence moaned as Twilight continued to ride her climax; feeling every single pulsation of Twilight’s penis as it squirted load after load deep inside of her.

“Y-yes… that’s it, Twi… let it go—ahhhn, inside of me…” Licking her lips, Cadence grinned to herself, enjoying the view more so than the act.

“Haahnnn~ ahhh~ Ca-Cadence…” Twilight could string a coherent sentence together. “M-more… I wanna c-cum more… I wanna this f-feeling to last f-forever…”

Twilight’s horn ignited in a warm pink glow just as she removed her cock from Cadence's ass for the final time, still squirting its near-endless load all over Cadence’s back and wings; the stringy fluid sticking her feathers together.

"Haaah, h-how was it?" Cadence asked, assuming that their sexual liaison had ended.

But Twilight was not finished.

"I'm gonna..." Twilight huffed.

Cadence pushed against the ground as she felt Twilight’s still pulsating penis slip easily past the folds of her already lubicated labia and plunge deep straight into her vagina.

A tremor of pleasure rocked Cadence into a throaty moan and although she was utterly thrilled to finally attain further pleasure from Twilight's cock, something terrified her into thinking rationally through the pink fog of lust. “Stop! Twilight!” Cadence looked back at Twilight’s glowing horn then down to the odd glow animating from her crotch. “What are you doing!?”

“Fill you… up… wanna fill... you up...”

"You could make me pregnant, Twilight! Please, stop!"

Twilight moaned like a mare possessed as she locked her hooves around Cadence’s midsection to keep her in place, slamming her hips back and fore so that she could fully piston her cock thunderously into Cadence's drenched vagina, locking eyes with Cadence in her blissful and dominating daze. “Need, more… cum…” Twilight’s horn glowed brighter still. "S-scream, Cadence... s-scream... 'cause I'm going to... make you pregnant..."

Cadence did scream. As she pushed herself to her full height, her eyes rolled back into her head as Twilight was quite literally fucking her brains out.

"Ahhhhnnnn! Hahhh—Twilight! Twilight!"

And best of all? Twilight was filling her up.

And it felt... great.

The flood of semen that poured out from Twilight’s cock was easily felt as the pressure within her gut had started to rise to a point that she felt like she was about to erupt.

Every space of Cadence's womb was filling up with the hot sticky fluid and, for just a panicked moment, Cadence had realized that a terrible mistake had occurred… and it had lasted mere moments as she looked down under her body to watch with a blissful expression as her stomach began to swell.

“Y-yes, yes... f-fuck me more... do it... me... make me.... preg—nahhhh~"

With one final thrust Twilight, released a shuddering scream and pulled out, her cock slipping out of Cadence’s vagina, the long appendage hitting the floor with a hard and wet slap.

Staggering forward, Cadence moved a hoof under her body, touching her swollen stomach as she looked back to Twilight who had collapsed into a heap on the ground just behind her. “Ahn… I… I…”

With cum leaking out of of her anus and vagina, Cadence resisted with all her might to stop the natural desire to push back against the foreign, sloshing pressure that did not belong inside of her and with little effort and control, her body pushed back naturally, expelling substance.

Like a fountain, Twilight’s stored up semen erupted out of Cadence’s vagina as one giant wet slop; smacking the ground as if some pony had just dumped a full bucket of water onto the floor behind her.

The sudden rush of expelled fluid pushed Cadence into a mind numbing, euphoric rapture that outright caused the mare to pass out.

“Oh-my-gosh! So cute! I could just eat the baby up!” Pinkie Pie bounced up and down on the spot as she peered into the cot.

Fluttershy gasped at Pinkie Pie, lifting a hoof to her mouth. “R-really?”

“Ah think it was a figure of speech, sugar.”

“Pfffft! Like I would really eat a baby! a jellybaby maybe... but that’s like, some seriously crazy fanfiction talk right there.”

“Say what now?” Applejack blinked at Pinkie Pie. “Fan-what?”

“You don’t wanna know.” Pinkie Pie levelled her eyes back at Applejack, making a zipping up motion with her mouth.

“Aaaaaanyway,” Rainbow Dash interjected, looking to the baby, “that’s some seriously big set of wings you got there, squirt! Maybe when you are old enough, Rainbow Dash could show you a few moves? After all, by then, I am going to be the best Wonderbolt there ever was.”

“That is most certainly a long way off, Rainbow Dash and… I have to say, Princess Cadence… Shining Armor... it is most unusual to see an Alicorn being born in this day and age. This is most unprecedented. You must both be so very proud.”

Shining Armor, who was standing next to his wife’s bed, was looking so pleased with himself, he was practically glowing with smug. “Well, she does certainly have her Father’s eyes and her Mother’s good looks!” He leaned against the bed, reaching over to kiss Cadence upon the forehead.

Cadence, although exhausted, showed little to no expression of joy. Every pony around her pretty much summed it up to the harrowing experience she had just went through, however, it had everything to do with what was currently laying next to her in the cot.

Or rather, the state of which the baby was in.

Pinkie Pie moved her hooves forward into the cot, ticking the giggling foal. “You’re so cute! Yes you are! Yes you are—WHOA!”

Alarmed, Pinkie Pie jumped back, blinking, pointing a hoof to the cot. “Wait-a-minute! If she’s a she then why does she have a winky?!”

Rarity blinked. “A what?” Peering into the cot and moving aside the blanket, Rarity lifted a hoof to her lips, gasping. “Oh… oh my…”

Shining Armour scratched at the back of his head nervously. “Yeah… so… she’s… not entirely perfect? But it doesn’t matter, does it darling?” He looked to Cadence, who only looked back at him with a smile. "We will love her regardless no matter what she is."

“Of course not, we… we will love her no matter what…” Cadence smiled at Shining Armor and then to the others around then... and then, drew her eyes to the petrified, pale Princess standing next to the door.

Twilight was rigid. She barely said a word to any pony.

A stiff cough however, had turned Twilight's gaze up to Princess Celestia who stood next to her, glaring back down at her,

Grinning up innocently to the glare, Twilight shrank back when she realized that the cat was finally out of the bag.

“Your mother is going to hit the roof when she realizes what has happened.” Celestia muttered.

“I… I’m sorry… I…”

“I don't want to hear a word of it…” Celestia leaned down, whispering to Twilight so that no one else could hear, “next time you get in on some action, invite me along, okay? At least if I am there I can stop you from doing something stupid like... oh, I don't know, impregnating you sister-in-law?”

“Yeah… yeah, sure.” Twilight swallowed hard. “I’m so… fucked, aren't I?”

“Oh yes,” Celestia nodded looking over to Cadence with a shake of her head, “completely.”
