A very horny Twilight Sparkle gets to the bottom of a trespassing sister-in-law and the rest as you can imagine becomes quite messy from there on out, whether Cadence likes it or not.
With Twilight Sparkle purposefully avoiding her brother since her ascension, Shining Armor asks Cadence to see if she could get to the bottom of the problem.
Instead, a very horny Twilight Sparkle gets to the bottom of her sister-in-law and the rest as you can imagine becomes quite messy from there on out, whether Cadence likes it or not.
Hint: she does.

(Featured on 15/07/2015 because I don't know why.)
Cadence could not help but feel that her husband was abusing his connections as a Prince of the Crystal Empire.
Who was she kidding? His actions were downright out of line.
What kind of brother employs a number of royal spies to secretly observe his little sister as opposed to the enemies of the kingdom, each one tasked in recording her daily routine in great and somewhat terrifying detail for his intense scrutiny?
It was at this particular juncture that Cadence thought it was right to intervene before it inevitably crashed down around him.
I understand he loves her dearly and would do anything to protect her, but, I think he is going a little bit too far just to find out something he could simply ask her.
It’s kind of embarrassing… and what is worse? He won’t even admit it… however, I know exactly what the problem is here. He’s afraid his little sister has finally met her special somepony and is doing…
Cadence blushed at the thought as she calmly walked through the halls of Canterlot Castle.
Well. She’s a grown mare now, so, I don’t see what the problem is if she is exploring herself with others. But, I suppose I will soon find out the truth from the mare herself. A little bit of girl talk between sister-in-laws will clear this all up and I can finally settle his mind…
Or unsettle it, if it is indeed a stallion.
Twilight Sparkle had been acting very strange since she ascended as a Princess. She had all but cut ties with her brother and even refused to join Princess Celestia and Luna on visits to the Empire, which prompted many sleepless nights for the Prince because he just couldn’t stand the notion that his little sister might have found another stallion to depend upon.
Cadence could not help but think it kind of cute. If anything, his concern (although excessive at this point) only deepened the love for her husband. He was too kind and caring for his own good, at times.
That and he’s a rather big crybaby, Cadence added as an endearing afterthought.
The two siblings only recent mode of contact was the weekly exchange of letters and even then, they were short and to the point.
Upon arriving at the entrance to Twilight’s chambers, Cadence knocked and waited for several minutes. Hearing no response, Cadence repeated the action a few more times before resorting to interrupting a passing guard, inquiring as to the whereabouts of her sister-in-law.
Discovering the mare was preoccupied in the library, a sudden and rather dangerous idea came to her.
Twilight Sparkle used to keep a detailed record of her thoughts and actions throughout the day…
A diary of sorts. If there was ever a place to search for the answer, it would be there.
Cadence infiltrated her sister-in-law’s bedroom all for him, and to be perfectly honest, she felt more than a little bit guilty for what she was doing.
But she had to know the uncensored truth.
After all, Cadence had promised him.
Only love could change a mare so suddenly, Cadence thought as she glanced under the mare’s bed, smiling as she noted a plain white book hidden away towards the back.
The discovery of Twilight’s diary had prompted Cadence to lock the bedroom door magically, just in case somepony happened upon her trespass.
Content that she was safe for the moment from any surprises, Cadence took the diary and headed over to the bedside cabinet, placing the book upon it as she flicked through to the latest entries penned on the crisp and clean pages.
Bizarrely, some of them were stuck together.
Glue? It’s not like Twilight to be this messy or reckless with her books.
Cadence sniffed the air.
It kind of smells strangely musky though… like Shining.
Pushing the thought from her mind, Cadence carefully parted the stuck pages to reveal a rather large entry.
Ah ha, here it is. Her most recent entry… huh? The writing looks quite rushed. This is far from the neatness I am normally used to from Twilight’s letters.
I don’t know what happened to me since becoming a Princess, but I have grown very fond of the addition to my anatomy.
Addition? Cadence blinked, clearly confused by the comment.
Before, whenever I felt turned on by anything, I simply yearned for something to fill me. A hoof… my toy. Once I achieved my orgasm, everything felt… great… resolute… blissful, you know?
I felt satisfied.
Oh… I… I shouldn’t be reading this… Clearly affected, Cadence blushed, though continued to read regardless.
But not anymore.
This is something different.
Since becoming a Princess, no matter how many times I release my tension, I just want more.
Is this what stallions feel? The overwhelming urge to feel something hot and moist around them constantly? Desperate to experience the sudden buildup of pressure that with each stroke erupts into a frenzy, as they work to achieve that heart-stopping, silent scream as they ejaculate their hot semen inside of their lovers…
Cadence quickly stole a glance to the door. “Twilight… this is… this is, so…”
...the mind numbing sensation followed by the shattering rush of something rushing out of you, seeking to smother whatever surface it can… to impregnate…
Before the concept of pregnancy somewhat scared me and yet now? The idea of… cumming inside of another mare without protection—the concept, it’s just so thrilling to think about!
As time goes on, my every waking thought has been to satisfy the sleeping, lusty monster inside of me… and I can’t stop touching myself whenever I think about it.
I can’t stop making myself cum.
Cadence was flabberghasted. She was not entirely sure if she wanted to read any more.
I used to masturbate maybe once a week to relieve the stress of my duties, but now I can’t stop. Everyday-no, every morning and every evening! Whenever I am alone and I get the chance I have to jerk one out.
What’s worse? I can’t stop thinking of her.
Her? Cadence swallowed hard.
I… I need her.
No... I don’t need her.
I must have her.
I want to cum in her… with her… on her face… on her flank—in her flank! On her tongue—her lips—in and on every part of her! I want her covered in my semen and begging for more as I masturbate into her gaping mouth!
Cadence took a few steps back, her eyes still locked upon the dairy, shocked to the core as almost every part of her told her to turn around and trot away… and yet, there was one small part of her that wanted to know more.
A small part of her was perversely interested in the inner most secrets of a mare she once thought pure and innocent.
Returning to hovering her gaze above the dairy, Cadence turned the page hesitantly.
Just thinking about her as I write these words… I’m hard already.
I need something to fuck.
I want to fuck her with my cock and make her scream!
Cadence quickly tore herself away from the bedside cabinet as if the furniture had caught fire, blushing red and utterly at a loss for words as she retreated, unable to read anymore of the smut or be anywhere in its vicinity.
“C-cum inside? W-what? Who?” A bigger question lingered at the forefront of that list and it was one that confused her exceptionally. “... already hard? B-but… that…”
How? Twilight’s a mare… she doesn't have the… thing, to—
The bedroom door handle’s sudden movement caused Cadence to whirl about and stare wide eyed in a panic, momentarily forgetting she was trespassing uninvited. She was glad she had locked the door upon entering because the voice on the other side caused Cadence’s hairs to stand up on end.
“Huh… I don’t remember locking the door.” A long suffering sigh huffed from the owner of the voice. “Don’t tell me it’s jammed again. I really need to ask somepony to get this fixed.”
Oh, no... it’s Twilight! I got to hide!
Searching the room desperately, Cadence brought her gaze to the closet and quickly dashed on over to it without thinking.
She hadn’t a moment to lose. Twilight could teleport herself in at any moment! She had to hide herself and she had to do it fast!
Throwing open the closet with her magic, Cadence’s eye twitched as she gazed upon the space normally reserved for clothes, which she had figured she would easily hide herself amongst.
Instead, the space was stacked head-high with dusty old books.
For the love of… Cadence complained internally, though wasted little time in stuffing herself into the dusty, cramped space in-between the stacks of reading material.
Next, Cadence used her magic to carefully close the closet just as a flash of lavender bled through a slight crack in the doors.
Okay, Cadence. Just breathe slowly and don’t move. It’s far too early for her to go to bed so just wait until she leaves, then open the window and just fly out—
Cadence immediately cursed herself.
Why didn’t I do that in the first place?! Urgh… now I’m stuck here! What a fine mess you've gotten me into, Shining! The things I do for you...
But then again, what did she discover that she could tell Shining Armor, anyway?
Nothing, that’s what!
Cadence was fully not prepared to share his little sister’s most intimate and surprisingly erotic thoughts, especially if they were that… vulgar and… detailed...
Not to mention his little sister was thinking of a particular mare rather than a stallion.
I never knew she swung that way… I always thought of her as the studious, married to her work type… I figured Flash Sentry was more of her thing if she ever wanted to pursue a relationship… but then again, he is kind of a mess.
“Well, I suppose it saves me locking the door.”
Twilight’s voice broke Cadence out of her thoughts, causing the Crystal Princess to bring an eye close to the crack in the door which happened to afford a perfect view of the foot of Twilight’s bed.
Cadence silently observed as she watched Twilight Sparkle walk into view and sit at her bed, stroking her…
WHAAAAAAAAAAAAT?!
Aghast, Cadence drew her gaze away and clamped her hooves over her lips to prevent the yelp of surprise from spilling out of her.
How is this possible? I would have noticed something like this when she was a filly! And I am pretty sure this is something Shining would have warned me about way in advance! This is… this has to be some kind of dream...
Right?
Leaning forward to peer out of the closet once again, Cadence observed as Twilight laid at the foot of her bed, stroking the long phallus that protruded between her rear legs.
“C-cum…” She could Twilight whisper hotly to her lonesome self.
It’s… it’s massive. Bigger than—
No! This is not something to think about… this is your sister-in-law and she’s… your brother-in-law? I don’t understand this situation.
Just what in Equestria is going on here?!
Swallowing hard, Cadence quietly shifted in the confined space, her erect wings making things very awkward to maneuver without drawing suspicion towards her hiding place.
Twilight was going to town on herself. There was no desire behind the strokes that caused the young Princess to writhe and pant upon the bed. Her strokes were so quick and desperate that Cadence could almost imagine that the mare was trying to rip the appendage off from the root.
“Ahhhn~mpnh!”
Cadence observed as the mare arched herself forward and plunged the tip of her own penis into her mouth and began to suck noisily.
This… this is… just… impossible…
“Mmmnnph~” Slurp. “C-Cadence… suck me…”
Wait… w-what?
Cadence pushed an eye closer to the gap as her name was mentioned.
Blushing hard, Cadence glanced back at her wings, cursing their current erect state.
This has to be a dream. Some kind of, weird, Discord influenced dream!
She wrinkled her nose.
“ACHOO!”
Cadence froze, feeling the blood drain away from her face as she thoughtlessly released a sneeze she wasn’t expecting.
Quickly she pulled back from the gap, covering her muzzle with her hooves.
Crapcrapcrapcrap!
“H-hello?” Came Twilight’s cautious tone. “I-Is somepony in there?”
“Oh, no…” Cadence whispered as the doors to the closet slowly opened, revealing Twilight Sparkle standing with both of her eyebrows raised in shock at just who was hiding in her closet.
“C-Cadence?” Twilight asked incredulously. “Why are you in my closet? How long have you… um, been there?”
“OH!” Cadence smiled nervously, laughing while she struggled to keep her eyes away from the large cock hanging from underneath Twilight’s body. “Funny story, I was… experimenting with a teleportation spell and I just so happened to appear here! Funny, right?”
Twilight Sparkle blinked. “You accidentally teleported halfway across Equestria into my closet? That seems rather specific.” She raised her eyebrow.
“Y-yeah! Funny that! Heh… Oh well! I best be off and try and work out the kinki—I mean figure out what went long—wrong!” Cadence removed herself from the closet and moved past Twilight Sparkle, clearly embarrassed and heading straight for the door.
Upon attempting to depart, Cadence found herself trapped.
She had forgotten she had locked the door.
In her panic, she quickly turned from the door and made her way towards the window, only to be stopped by Twilight Sparkle. The younger alicorn blocked her path, looking very suspicious and yet, if her reddened cheeks were to be believed, easily as embarrassed as Cadence was.
“You heard, didn’t you? You… you saw?” Twilight narrowed her eyes.
“Oh, I… uh… saw nothing?” Cadence faked a smile, struggling to look at the younger mare in the eyes and not the thing that kept grabbing her attention.
Twilight sighed. “I can see you looking at it…”
“Twilight, listen, I don’t know what I saw and to be perfectly honest? I think this is just some kind of dream that I need to wake up from badly, so, if you will excuse me, I will be leaving now.”
Stepping around Twilight, Cadence made yet another attempt to escape, and was intercepted again by Twilight Sparkle.
“You enjoyed it.” Twilight pointed a hoof to Cadence’s still erect wings. “Didn’t you?”
“I… I didn’t! I am just shocked that I would dream something so… something so—”
“Erotic?” Twilight finished with a gentle and somewhat sultry tone of voice that caused Cadence to blush again.
“Well, yes but I—”
Immediately Cadence was cut short by a needy and intrusive kiss that crashed against her lips, causing her to yelp and retreat in an attempt to flee. However, Twilight had locked her forelegs around the older mare’s neck and kept the kiss firmly in place.
A tongue invaded her mouth and she could do nothing to stop it.
Eventually, Princess Cadence ripped herself from the kiss by pushing her hooves against Twilight’s muzzle, her heart pounding against her chest as she breathlessly spoke. "T-Twilight! What i-in Equestria are you doing?!"
"If this is a dream, then it doesn’t matter what happens, right? Even if we kiss, even if we have… sex."
“S-sex?” Cadence stammered. “But… this isn’t right! Even if this is a dream... This is… I have to wake up. I don’t want to have sex with you, even in my dreams!”
Twilight shuddered in anticipation at the word coming from the other mare’s lips, even if it brought rejection along with it. "I don’t care... I want to feel my c-cock inside of you... I want your warmth to consume it. I want... I want us. So badly... So much so that it is driving me insane! It feels like something is building up inside of me and it is just begging for me to let it out... to let it, all, out..." Twilight's sultry eyes narrowed upon Cadence's lips. "All, over..." She added as a lustful afterthought.
"But I love your brother; we're married! I'm your sister-in-law! There's no way I can… I just don’t feel that—" The sudden presence of Twilight’s body pressing up against her caused Cadence to shiver and take a sudden step back as something wet and hot poked her side.
She knew what it was and dared not to look down.
"He doesn't need to know. Nopony needs to know, Cadence. If this is indeed a dream then I never want us to wake up." Twilight pursued, closing the gap. “You watched, didn't you? You watched me masturbate just now. You were intrigued, weren't you? Why else did you hide in the closet like that for so long without saying a word? You were excited, right? Like how excited I am right about now, right?”
"I-I don't know..." Cadence averted her gaze. "I... I'm not quite sure... I thought you were... I came here because Shining told me you were acting strange around him lately. You've been quite cold towards him and myself the last couple of weeks, but I never thought that it was because—"
"—your sister-in-law was masturbating to the thought of plunging her long, hard, cock inside of your flank?” Twilight interjected in a seductive groan, “I've been avoiding him because I almost can't control myself, anymore. I’ve wanted to say something since the wedding about my feelings but… but... but now I don't care. I will make you mine and I don't care what you say or what my brother thinks of me… I’ve always had this feeling for you since I was a young filly… I didn’t understand my feelings at the time but, ever since you married my brother and I became a Princess, I... I want to hear you scream my name… I want you to beg for me to stop as I make love to you... I love you and I want to show you just how much."
“Twilight, you can’t… I don’t like you in that way.”
Twilight’s pleading voice became desperate. “Please, let me show you. Just this once?”
Cadence pressed her back against the bedroom door, forcing her to rip her wide-eyed gaze away from the large, throbbing cock hanging below Twilight Sparkle. “N-no… I would never… Twilight, this is wrong. We’re family! You’re my step-sister and I could never love you like I do Shining Armor. I would never betray him to anypony… and… this is just wrong! I’ve known you since you were a filly and I just can’t do this! Please, control yourself.”
“I-I know. I know you would never feel the same way but yet, I just have to try, you know?” Twilight took a step back, tears forming in her eyes, her wings drooping towards the ground. “Cadence, you’re… not even curious…? How good I can make you feel?”
“Twilight,” Cadence reaffirmed in a stronger tone, narrowing her eyes upon the younger Princess with an air of authority, “I’m sorry, but I can’t. I’m leaving.”
Cadence barely looked at Twilight as she brushed past her, heading for the window so she could depart from the bedroom. “Don’t worry. I won’t tell Shining about this… it’d break his heart to know his little sister was thinking about taking away the mare he loves.”
“W-wait…”
Twilight’s trembling voice caused Cadence’s steps to pause. Turning, she looked back at the younger Princess with a slight frown, though tried her best to not appear as annoyed or as uncomfortable as she felt.
“Yes—wha?!” Cadence was met with a flash of light that momentarily dazed the mare, causing her to sway and fall back onto her flank.
Confused and blinded, Cadence drew her hooves to her closed eyelids, pressing tight against them as the strange fuzz bled throughout the rest of her body, spanning from the tip of her horn down throughout the rest of her body.
“Cadence… are you okay?” Twilight enquired, concerned.
Rubbing at her eyes, Cadence opened them, her stunned state boiling into anger as she realized what had just happened. “Twilight! How could you? You attacked me!”
“I’m sorry but there was no other way I could think of to fix this!”
“What do you mean? Fix what?” As Cadence’s vision cleared, her heart felt as if it had stopped the moment Twilight Sparkle’s concerned face came into view.
A wave of emotion crashed through Cadence’s body, causing the mare to tremble and gasp, forcing her to push her hooves to her lips to contain the noise.
The very image of Twilight Sparkle had caused her body to react in quite the unexpected manner. For her previous turmoil of betrayal was instantly replaced with an awe and wonder that felt unnatural.
“T-Twilight…” Cadence whispered softly as she slowly got back to her hooves. “W-what have you done to me?”
“I-I’m sorry, Cadence, I just—”
“Why… why do I feel… I want it?” Cadence groaned as her eyes slowly dropped to Twilight’s cock, shivering as she approached it, her mind screaming for her body to stop but to no avail.
Cadence’s head drooped low as her lips parted, breathlessly whispering her words the closer she got to the glistening tip of her sudden and unexpected desire. “I-I need it.”
Parting her lips, Cadence felt her tongue flattening as she slid Twilight’s long throbbing penis into her mouth and down her throat.
It’s filling my mouth, my throat... and it fits so well.
But... this is wrong!
This… this isn’t right—I’m not this kind of mare!
Cadence pulled back her lips from Twilight’s penis, the twitching, throbbing appendage departing her mouth with a resounding wet pop. Her eyes remained transfixed upon the tip as she noted the merest leakage of a milky white coloured substance form into a tiny pearl that trickled down her cock.
Cadence immediately wanted to taste it.
But… but I want more… I want so much more.
For reasons that both horrified and greatly thrilled Cadence, she could not help but slither her tongue out to lap up the pre-cum like a mewling cat.
It tastes so good…
She savoured the musky, salty taste, swirling her tongue around the inside of her mouth; she battled with her magically forced state of sexual bliss, but could not prevent her body from moving of its own accord as it reacted to the flare of sexual energy she longed to release.
Cadence felt dirty and it felt good.
No! This shouldn’t feel good!
I should be fighting this!
Drawing back, Cadence trembled in uncontrollable anticipation as she looked up at Twilight with a mixture of betrayal and unbridled appetite, tears forming in her eyes.
But I… want it...
Twilight took a step back, her head shaking side to side. “Cadence this is… I’m so sorry!” Guilt ridden, the mare opened her wings and quickly curled them down around her body to hide the still erect appendage that Cadence now wanted, needed. “Give me a moment… I-I’ll change this! I’ll…”
I want her inside of me.
“T-Twilight… h-how could you?” Cadence inclined her head away as she gnawed at her lower lip, struggling to keep herself from staring at Twilight’s undercarriage.
I want to feel good.
“I… I don’t expect you to forgive me, but I… I’m sorry! I was just so desperate that I… that I didn’t think and I was just thinking about… what have I done? I’ve ruined everything.” Twilight clenched her eyes shut as her horn ignited with its lavender hue. “I think I remember the counter-spell. I can fix this, Cadence. We can just pretend none of this happened and Shining won’t know that I… that I tried to…” The mare clenched her eyes shut. “I’m a terrible pony. Just give me a moment to—”
I must… I must have her!
Suddenly knocked from her hooves, Twilight yelped in surprise as she felt Cadence smash into her, wincing as she was knocked onto her back.
Cadence quickly straddled Twilight, her face contorted into a grinning mess of blushing bliss, panting heavily as sweat dribbled down her brow. Savagely she ripped Twilight’s wings from around her under carriage and pinned them to the ground, allowing Cadence to stare manically wide eyed at Twilight’s still erect penis.
“C-Cadence! Wait a minute!”
“W-why? Y-you said you wanted me, r-right? You did this to me, so...” Cadence whispered as she slithered her lips close to wash her hot breath over the end of Twilight’s penis, “then… l-let me take you… like you wanted me to...”
“I… I…” Twilight shook her head, swallowing hard as her body froze, watching as Cadence’s lips descended upon the tip of her penis once again. “C-Cadence, what about Shining? I… this isn’t you… I didn’t mean for this to happen like this, I just reacted and—”
Shining…
Cadence’s mouth wrapped around the cock and began to suckle upon the tip, her eyes rolling back into her head as she heard Twilight’s satisfied groan.
I don’t care.
Maneuvering her head, Cadence flattened her tongue to allow Twilight better access and drove her mouth down around the thick shaft. She forcibly parted her throat and held her breath so she make it all the way to the base of her sister-in-law’s penis, with her nose buried in the large bulbous ball sack for several seconds to allow Twilight to feel the full extent of her throat.
I can feel it…
It’s filling up every inch of my throat.
I can feel her twitching.
She clenched her eyes shut so she could focus on ignoring her gag reflex, spluttering as her body salivated to aid in her throat’s lubrication, while her throat pulsed as it sought to swallow the obstruction .
Holding it for as long as she could, she suddenly tore her mouth away from Twilight’s cock, coughing and heaving as she gasped for air.
“S-stop… I-I’m sorry… I… AHN!” Twilight’s words were cut short as Cadence took a second plunge, though this time she did not pause in her plunge, thrusting back and forth with wild abandon. “I-I can’t let you… Mnnn~”
Every single stroke of Twilight’s penis as it penetrated her throat caused Cadence to hasten her attempts, the alluring and near grotesque sounds of Cadence’s efforts culminated in a series of wet coughs and loud spits as she drooled out the excess lubrication down onto Twilight's testicles.
Opening her eyes so she could look at Twilight, Cadence drew her lust crazed stare upon the mare’s blissfully contorted face.
Whether it was right or not, Cadence could not help but feel that there was more at work than the spell that Twilight had cast upon her.
Her overwhelming desire to have Twilight’s penis inside of her was one thing, but was she truly enjoying the fact that Twilight’s face was twisted into a euphoric state of bliss all because of what she had done?
It felt intoxicating.
No, it felt empowering to know that she could force Twilight to make the same face Shining Armor made when he enjoyed her ministrations.
Maybe that was why she felt strangely attracted to the mare?
This… this isn’t me…
And with Twilight, no less...
But I… I can’t deny I… I did find watching Twilight masturbate a turn on… I… I’d never act on it though.
I never thought I would do something like this and yet, why does it feel so… right?
And yet, isn’t this incest?
It’s just so, so wrong and yet…
It just feels so right!
Cadence’s eyes fell half lidded and content as she lifted a hoof under Twilight’s tail, finding the tight pucker of Twilight’s anus, massaging it in a slow clockwise-like motion that immediately caused Twilight’s body to tense up.
Cum… Twilight.
“W-wait… n-not there! I—”
Cum!
Cadence pushed the tip of her hoof into the tight hole and obtained an immediate reaction that caused her to grin. She felt Twilight suddenly tense up and spasm.
I want your cum, Twilight!
I want to taste it!
I want it!
I need it!
Twilight’s wings sprang open as she ejaculated, whining and writhing as she she pressed her hooves firmly against her lips to muffle the scream. Cadence positioned herself to accept the spurts of hot semen to coat the inside of her mouth and for a single string of white to cling to her muzzle and lips.
It almost tastes the same as Shiny’s... but, sweeter? There’s something different about it I can’t quite put my hoof on.
Collecting what she could in her mouth, Cadence tilted back her head and parted her lips, writhing her semen covered tongue about the inside of her mouth, coating her teeth and lips before allowing some to dribble onto her cheek.
This… this is amazing…
Out of the corner of her eye, she observed Twilight’s exhausted form sprawled before her, near motionless as her cock twitched and continued to pulsate mere trickles of her seed down the shaft.
Why did I resist?
How could I resist?
You’ve made me dirty and I… I like it...
Cadence slowly leant over Twilight, bringing her lips to hover above Twilight’s panting face and drooled the mare’s own cum down into her mouth.
I want to be dirtier. I’ve always wanted to do things like these with Shining. I’ve always wanted… to do more.
Explore every part of him.
Twilight received and savoured the taste of her secretion mixed with Cadence’s saliva, swallowing noisily with each mouthful.
I want more.
The momentary calmness passed however, when Cadence plunged her glistening lips against Twilight’s own. Both lost themselves in the sheer ferocity and passion of the kiss.
Their hooves intertwined and their bodies crushed against each other as they rolled about on the floor, each fighting the other for dominance. The sheer savagery displayed resembled two dogs locked in combat, each nipping at the others’ flesh between kisses, only to illicit yelps that spurred the other on.
It wasn’t until Twilight sat atop Cadence, pinning her forelegs to the ground with magic, that the dance finally came to an end. .
Cadence gazed up at Twilight with a silly smile, panting heavily as she awaited the victor to take the spoils, but it was then that Twilight suddenly became the voice of reason.
“C-Cadence, w-we…” Twilight swallowed hard, the taste of her own seed lingering upon her breath, “we have to stop… this has gone too far…”
No, Twilight, this has not gone far enough.
I want more.
I want to go further!
“Fuck, me…” Cadence whispered haughtily.
Twilight’s sprung back at the request. “Cadence… I-I can’t. Not like this… this is wrong… I… I forced this on you.”
You opened my eyes to the truth.
I was turned on while watching your masturbate.
I’m a deviant just as much as you are.
These are the kind of things I only ever dreamed of… things that I only ever fantasized about in my deepest and darkest desires.
Things I never thought I’d explore.
“It doesn’t matter, Twilight… I want it…” Cadence leaned her head up off of the ground, her words sultry and sickly sweet. “I want you, Twilight… I want you to… fuck me… to force yourself on me. Take me, Twilight…” Cadence whispered seductively. “Take what is yours.”
“What about big brother?” Twilight whispered as she looked down along Cadence’s body, her eyes locked upon a particular area that her cock ached to enter. “If… if he finds out that I—”
I don’t care anymore… I don’t care if he finds out.
“Twilight.... do it,” Cadence moaned her words as anticipation spurred her body to thrust upwards towards the cock, “do it like you wanted in your diary… steal me from him… make me yours.”
Cadence clenched her eyes shut, listening to Twilight’s breathing as she felt the tip of Twilight’s penis gently stroke her moist entrance, groaning as it brushed against the red hot nub of her clitoris.
“Stop teasing me…” Cadence moaned, cracking open an eye to observe Twilight’s apprehensive expression, “stick it in already.”
It felt like an eternity as she felt the bulge of Twilight’s cock fill her up. As Cadence looked down, she could just about make out the impression of something long and phallic under the flesh of her belly slowly traveling upwards like an invasive snake, until eventually Cadence felt a sudden pang of pain as Twilight’s cock hit the very end of her womb.
And what was most fascinating? Twilight possessed a couple of inches to spare.
“You’re b-bigger than Shining... much bigger.” Cadence commented with a bubbly giggle.
“C-Cadence… you’re so warm… it’s… I’ve never felt anything like this before…” Twilight began to thrust, gently at first, just to feel Cadence encompassing her aching cock.
Cadence drew Twilight’s eyes with her own and the two mares quickly became entranced by the other. As Twilight picked up the pace on her thrusts, their pants and moans unified into a blissful cacophony that spurred Twilight into wilder, more desperate thrusts.
With Cadence’s vagina perfectly drenched for the occasion combined with Twilight’s cum and saliva lubricated penis, it was a smooth glide with little to no difficult in and out of the mare.
There was no longer any restraint from Twilight Sparkle. Each thrust reverberated throughout Cadence’s body, spreading goosebumps across the flesh in sharp jolts of bliss.
And Cadence liked it.
Each sickening slap against her found Cadence’s mind awhirl in a constant haze of joy, satisfied beyond comprehension and aroused beyond belief that she was being violated with the full knowledge that, eventually, Shining Armor would find out.
D-Do I want to be found out?
The concept drew a shiver along her spine the more she thought about it. Her tongue lolled out of the side of her gaping mouth as she weakly laid back and surrendered to her fate, her rear legs spread wide to fully allow Twilight access to her deepest depths.
It was at this point Cadence felt her orgasm and her moans rising to a crescendo. Just as she was about to hit the breaking point, Twilight pulled out, garnering a groan of disappointment as she dazedly leaned her head up to frown at Twilight.
“W-why did you stop?”
“I… I’m close,” Twilight whispered as she stroked her penis, drawing back from a disappointed Cadence, “l-let me cum on you, please? On your belly… I’ve been wanting to do that for so long now.”
Shaking her head, Cadence quickly manouvered herself so that she was upon all fours with her flank pushed right up into the air. Her tail drooping to one side away from the swollen folds of her ravaged vagina, she used a hoof to pull at her flank to purposefully part the folds of her glistening labia for Twilight to see in all of its glory.
“N-no… do it inside me…”
“E-excuse me?” Twilight couldn’t avert her eyes, not for a second, from the swaying flank presented before her.
“Cum,” Cadence reaffirmed with more certainty, her tail swishing impatiently, “inside of me.”
Twilight shook her head weakly, still trying to make herself cum. “B-but if I do that—”
“Twilight Sparkle!” Cadence raised her voice, glaring back at Twilight for a moment before smiling sweetly to her. “Do it, or you’re going to bed early with no happy ending.”
“But!” Twilight blinked, the strokes on her cock halting altogether. “Y-y-you wouldn’t!”
Cadence grinned, arching a brow. “Wouldn’t I?”
“I… I’m not so sure about this… what if you… you know? What if you become—”
Cadence drew her sultry eyes down her own body, pausing a moment to think about it. “If it happens, then we’ll just pretend it’s Shining’s. I mean… after all, who is to tell it isn’t his? I’m sure it’ll look the same.”
Carrying Twilight’s child… while pretending it’s his?
Why do I find such a concept so exhilarating?
Am I that sick?
“In fact,” Cadence winked, “I think it’ll be kind of exciting, don’t you?”
Twilight swallowed hard. “I’m not so sure… I’m not ready to become a parent… I’m still too young.”
“You cast that spell on me to make me this way; you, wanted this from the very beginning. So, whether you like it or not, you started this mess and brought out a side of me I would willingly allow myself to reveal to anypony. You better hope you finish it or so help me, I am going to tell Shining Armor exactly what his little sister has been thinking about his newly wedded wife.”
Twilight lifted her brows, stunned that Cadence would go so far as to blackmail her into the act. Momentarily conflicted, Twilight eventually felt her lips curl into sultry and somewhat sadistic smile.
“Fine.” Twilight relented in a huff as she placed her hooves either side of Cadence’s flank, bringing the tip of her cock to the folds of her vagina. “I’ll finish it. But I am going to make you regret it.”
“Oooo, how frightening… Remember who was the pony who used to change your diapers? That was me, Twily. You can't make yourself sound threatening towards me even if you were Nightmare Moon herself with that kind of image in my mind.”
Twilight frowned as she narrowed her eyes upon Cadence’s flank. “Oh yeah?”
“Yeah.” Cadence replied indignantly, smug that she had won the argument.
Until she felt something forcibly penetrate and spread her anus painfully apart.
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?”
