                  Princess Cadance's Plan                  
//-------------------------------------------------------//
Princess Cadance's Plan
"Ouch! O-Okay, pull back a bit?"
Shining Armor lets out a soft sigh, masking it as a moan as he pulls out until a little less than a third of his dick is inside of his little sister's dripping wet pussy. She sighs in relief, her inner muscles spasming slightly around him and causing his muscles to tense as he resists the urge to thrust back in until he's sheathed completely.
"Perfect." Princess Twilight clenches gently, giggling at the grunt it elicits from the stallion above her. "C'mon, big boy." She wiggles her hips. "Keep going!"
He huffs in response, bringing up one hoof to give her a gentle smack on her left cutie mark before pulling out nearly all the way, then pushing back in. "Right there?"
"Nnh...yes, there, now stop teasing me!" She turns to give him a harmless glare, the expression falling apart as her brother starts thrusting at a steady, quick pace. Twilight falls facedown into the pillows before her, moans muffled yet still loud enough to echo off of the crystal walls of Prince Shining Armor and Princess Cadance's bedroom. Her hips push back against his thrusts, forcing him to pull back several times - with no small amount of effort - to avoid hitting her cervix.
It also means that his dick doesn't get to experience the full joy of a mare's warm, wet womb.
He shakes his head to clear his mind, breaths coming heavier as he grips at Twilight's hips and thrusts faster. As she squeals and squirms beneath him, a small smile comes to his lips at the sight. The fact that she's gripping and twitching against his cock like there's no tomorrow also adds to his enjoyment, and as she reaches one hoof below herself to rub at her furiously winking clit, he leans down to nibble at her ear. Specifically her left ear, just at the base of it. Right where she likes it.
With a loud, whinnying cry of Shining Armor's name, Twilight's walls spasm around the white stallion's cock and a fine spray of marecum dampens the bedsheets. When her hoof falls limply to the mattress, a devilish grin comes to Shining's lips and, with a bit of effort, he manages to get his hoof in-between her legs. Briefly, he feels where they're connected and sighs appreciatively into Twilight's mane, grinning at the stretch of her cunt around him.
Then he flicks - gently, of course - at the lavender mare's pleasure nub again, and groans at the ensuing set of full-body twitches and whimpers from the half-comatose mare. Then he does it again. And again. His breaths turn into pants, his muzzle half-buried into Twilight's mane.
When he starts rubbing, he earns another squirt of juices from Twilight, followed by clenches so strong that they pull him to the edge of orgasm, and when she moans out weakly, "Sh- uhhhn- Shining Armooorrr...sss- suh- s-stop," he pushes in until the flared head of his cock nearly bangs into her cervix, tips his head back, mashes the frog of his hoof against her clit, and grits out Twilight's name before his heavy balls draw up tight against his body, glowing with the familiar violet-pink glow of his sister's magic.
She responds to the now-infertile semen rushing into her cunt with another weak twitch, her limp wings ruffling slightly.
He stays there, half-laid against his sister's back, for several long minutes in afterglow, until Princess Twilight comes back to life somewhat and wiggles with a grunt that sounds something like "geddoffame", so he does. She rolls over, and as his cock comes out of her during the process with a wet squelch, both of them giggle at the obscene sound before Shining moves down on the bed to admire his sister's creampie.
"Your fetish is showing, B.B.B.F.F."
"Oh yeah?" Shining Armor leans in and takes a long lick up Twilight's privates from ass to clit, licking his lips loudly and snickering at the squeal and jerk that it gets from her.
"S-Stoppit!" She winks several times due to aftershocks before her body stops jerking. "You know that that portal made me approximately three point seven six three times more sensitive!" She earns a stuck-out tongue from her brother.
"Oh, Shining. Stop torturing your sister! Goodness knows you've put her through enough today."
Both of them jerk at the melodic voice of Prince Shining Armor's wife, her violet eyes examining the exhausted siblings.
"I- Cadance!" Shining Armor sputters, cheeks glowing red as he tries - and fails, miserably - to come up with an excuse. "I can explain!"
"Please do." Her voice grows stern as she trots over, wings flared and her eyes narrowed slightly.
Shining Armor gulps. He resists the urge to chuckle as he hears Twilight do the same. "I- uh-"
"'Royal business', right?" Princess Cadance decides to explain for him.
"...yeah." He bows his head in apology, though it doesn't look as sincere as it should, considering the fact that he's coated head to hoof in sweat and his sister's cum is drying on his lips.
Princess Cadance rolls her eyes and comes closer to the two on her bed, leaning in to lock eyes with Shining Armor. "You are in very big trouble, mister." She gives him a hard kiss on the lips, savoring the taste of her sister-in-law's pleasure on - and in - her husband's mouth before pulling back with a soft hum of enjoyment. "If you're going to sneak off to fuck your sister instead of doing actual work, you should at least invite your wife."
Husband and wife flop onto their sides on that same bed, their chests heaving and hearts thumping as sweat cools on their bodies. For a while, only silence and slowly steadying breaths fill the air, but eventually a small giggle breaks the monotony.
"And here I was, thinking that you'd be too tuckered out to give me a good ride too," Cadance says with a breathless laugh. She scoots closer to give Shining a brief kiss, smiling brightly. The expression fades somewhat, though, as she notices the look of troubled contemplation beginning to form upon his face. "Shiny?"
He jerks slightly, his eyes refocusing as he blinks himself out of his thoughts. "Huh? O-Oh, yeah, it was great for me too." When he gets a small snicker from his wife in response, he frowns. "What? Did I do something funny?"
Cadance gives him a small bop on the side of the head before leaning in to kiss him again. "It was wonderful, but that isn't what I said." Her hoof comes up under his chin so that she can look him in the eye. "What's wrong, Shining Armor?" Her eyes narrow. "And don't give me any of that 'nothiiing!' nonsense."
Shining Armor's light smile fades at the question, then his ears flatten as his favorite excuse is promptly crushed into dust. After opening and shutting his mouth three times, he finally finds the right words for his thoughts. "...it's Twilight." When she doesn't respond, he huffs at the fact that, once again, she's forcing him to explain his problems further so that they can work them out together. She has no right to be such a perfect wife. "It's just that, ever since she came back through that weird portal thing, she hasn't been able to handle my full length."
She grins. "Well, that's somewhat your fault. You're the biggest stallion I've ever had, and that's saying something." Her levity eases up, though, and she nods. "So, you're frustrated." Cadance leans in to lock their lips, playing her tongue against his and sighing happily into the kiss. Once they break, she gives him a suggestive smile. "Well, I'm always up for a second round, Shiny, and I can take it all in all three holes. Would it help if we did all three tonight?"
The kiss helps to sooth his mind, and he feels himself untensing, practically melting into the loving action until it breaks. When she suggests a second round, he chuckles and considers it before shaking his head. "I...I don't know how to say this in a not-shitty way, but it's just not the same as my sister's, uh...y'know." An awkward grin crooks across his lips.
Fortunately for Shining Armor, Princess Cadance simply laughs and nods. "I still remember how relieved you were when I told you that it's only allowed if I get to hit that too." She purses her lips, her expression turning contemplative. "...so, then. What do we do about this?"
His heart stops.
"W-Wait, Cadance, I didn't mean it that w-"
"Shining Armor, for the love of Celestia, calm down." She snorts and boops his nose. "I was talking about Twilight. What do we do about her?" When she receives a confused cock of the head, she elaborates, "Twilight's body is literally designed to be able to take a stallion's entire penis. All mares' bodies are. She certainly had no qualms with it before that portal magic did whatever it did to her." She presses her hooves together, giving her husband an exaggeratedly evil little grin. "So: What do we do about this little conundrum?"
He presses one hoof against his face. "Something tells me that you're formulating a plan as we speak."
She takes his foreleg in her own and nods, kissing the ankle of it before saying, "First, we start with a simple little threesome. Then..." And as she explains her idea, she gestures with more dramatic sways of her hooves and sinister cackles. At one point, she attempts to flare her wings and nearly sends them both flying off of the bed.
Still, at the end of her speech, Shining Armor is once again floored by how smart his wife is. Maybe diabolical. That's why he loves her.
"Alright, you've convinced me, oh Mighty And Evil Cadance." He smiles and presses his forehead to hers. "I don't tell you how much I love you often enough. You know that?"
Princess Cadance closes her eyes and sighs contently. "You tell me just often enough, Shiny." She reaches down to slap his plot, earning her a squeak of surprise. "Now, let's get some sleep. We're doing this tomorrow."
"Oh!" Twilight squeals out in surprise as Cadance takes her forelegs within her magic and crosses them at the ankles, pulling them up above her head and keeping them there. "W-What're you doing, Cadance?"
"We're just going to try some light bondage. Nothing too intense, Twilight; this is all we're doing this time. If you like it, we'll try more." Princess Cadance leans in to give the smaller alicorn a long, heated kiss. It leaves the purple mare panting and somewhat dazed. Cadance isn't the Princess of Love for nothing. "If you don't like it, we won't do it again, and you can tell us to stop at any time. Okay?"
She only hesitates briefly before nodding. After all, Shining Armor and Princess Cadance have never hurt her before. "Okay!" Twilight smiles brightly. "I do like trying new things!" Her voices pitches up into a squeal as Shining Armor spreads her hind legs, the warm breath fanning out over her slit the only warning she gets before his wide tongue is laving over her clitoris in long, wet strokes. Her wings rustle frantically, attempting to spread but pinned under her body.
Shining pauses briefly in his ministrations to move up to his sister's teats, taking first one nipple then the other into his warm mouth to suckle on them gently. While this doesn't get the frantic writhing from her that he's so fond of, he still enjoys the breathless whines and whimpers that Twilight gasps out.
Her sounds are promptly cut off as Cadance leans down to kiss her again, their tongues playing together hotly and giving Shining Armor quite the nice view as he continues to lick out Twilight's cunt just how she likes it. She lasts through another six kisses before she breaks the seventh to buck her hips and demand, "Prince Consort Shining Armor, if you don't fuck me right this second, I'll break free and do it myself!"
That earns a fond laugh from the married couple currently ravaging her body, but Shining Armor complies, climbing up her body and putting him face-to-face with Twilight. It's a bit awkward to be with her like this, belly-to-belly, but luckily he has a loving wife that positions his tip to his sister's cunt, and with a push and a soft gasp from Twilight, he's in and steadily sliding in further.
Now that Cadance doesn't have Twilight's muzzle to herself and her only job is to keep the lavender alicorn's hooves restrained, she moves down to place a hoof on Shining Armor's rear, massaging the flesh there and practically purring at the sight of her favorite cock moving into her sister-in-law's pussy.
Both of them wait for it.
Princess Twilight breaks her kiss with Shining Armor to squeak out a soft cry of pain, followed by, "Okay, stop there!" She giggles. "You'd think that you would remember where to stop by now, huh big brother?"
Princess Cadance subtly tightens her magical grip on the other mare's ankles, glancing at Twilight's hind hooves to make sure that she's out of kicking range.
Shining Armor simply responds by kissing her again, tracing the contours of her tongue with his own as he pulls his hips back. When he pushes back in, Twilight attempts to break the kiss, her whimper muted but clear in its discomforted nature, but he keeps their lips locked as he starts up a steady series of thrusts, his tip meeting her cervix just enough that she feels it with each press inwards.
With a wet pop, their lips finally leave each other, and Prince Shining Armor's moan nearly echoes off of the walls. It's only an extra inch or so that he's been granted so far, but his sister's pussy is always so warm and wet. Logically, he's aware that quite a few consenting vaginas are like that, but his cock and his emotions enjoy the added bonus that this is his baby sister's pussy. His hips shove in just a little bit harder.
"Ow! Sh- Shining," Twilight whines out, her eyes watering slightly, "that hurts." She struggles at the teal surrounding her forelegs' ankles, a bit of a scowl forming upon her face. When wiggling her hips only earns her a moan and an even harder thrust, followed by a much deeper, sharper pang of pain as her brother's flare bangs into her cervix, she doesn't try that again. Her eyes dampen further. A tear threatens to fall. "Seriously, Shining Armor, this isn't funny! Cadance, let me go. I-I don't like this anymore, okay?"
Princess Cadance simply places her other forehoof upon Shining's previously unoccupied cheek and pushes while he's at his deepest.
Shining Armor's moan nearly covers up the sound of Twilight's surprised squawk. The sounds she makes afterwards, though...
She sniffles, her face screwed up as she desperately tries to avoid crying. She can't stop her cunt from rippling over her big brother's cock, both from the faint pangs of pleasure she's still getting and from the much larger, more deepset jolts of cramp-like agony starting to spread throughout her entire lower body. The sounds escaping her body with each thrust could nearly be mistaken for moans, if not for the fact that each low, sighed-out wheeze is more and more imbued with fear, betrayal starting to shine clear as day within those big, purple eyes as she stares up into Shining Armor's pleased face.
"Aw, c'mon, Twily- hff- don't you like this at least a little bit?" The smile he gives her is the same half-smirk he's given her for all the years they've known each other: Full of confidence, the cockiness only half-exaggerated, and with all the care in the world.
It breaks her heart to see as his cock grows closer and closer to breaking down the entrance to her womb.
"NO! I-I'm saying 'no', B.B.B.F.F.! I don't want this anymore, do you- snff- understand me?!" A proper sob leaves her drooling lips, and although she's a grown alicorn mare now, in this moment, she looks for all the world exactly like the little filly she once was when she was crying over a ninety-nine on a test grade. Another drawn-out wail leaves her as she realizes that her big brother, the one that's supposed to protect her, is the one making her cry like this. The tears start coming in earnest, then.
Princess Cadance's magic tweaks at Twilight's clitoris gently, the shimmering aura surrounding the sensitive nub and stroking at it in the ways that she knows the other mare likes. "Oh, Twilight, please don't cry..." When her sister-in-law bawls even louder, she presses her hooves to Shining Armor's rear once again. Once his hips are pulled back all the way, she pulls upon the earth pony aspect of her alicorn magic and shoves as hard as she can, her forelegs glowing a weak teal with the force of her push. That nearly-cruel, scheming little grin returns to her face.
She just needs to get Twilight to get through this once. Then she'll see the light. She knows that the lavender princess is tough enough to see this through to the end.
When his wife's hooves meet his plot, he braces himself. The familiar feeling of Cadance's magic soon meets his skin, and his hips move forwards faster than he could've managed on his own.
And as Princess Twilight's cervix is broken through, three moans of different natures ring through the air of Prince Consort Shining Armor and Princess Mi Amore Cadenza's bedroom.
Shining Armor's head tilts back and he whinnies as over half of his cock sinks into his sister's deepest depths.
Princess Cadance moans softly at the sight, her hooves leaving her husband's bottom for the moment so that she can lick at the penetration point.
And Princess Twilight positively shrieks.
He doesn't stop to savor the warmth and the tightness. Not for much longer than a few seconds, anyways. No, instead, Shining Armor begins to truly hammer his hips into Twilight Sparkle's pussy, his hips thrusting in and out so quickly that Cadance must move her head back away from where his body meets Twilight's for fear of gaining a black eye from his swinging balls. His head dips, sweat quickly beading along his brow as he grunts and presses his forehooves into the mattress on either side of Twilight's head, face twisted into a grimace of pure pleasure.
"Shining, dear, don't use it all before you get to little ol' me!" Cadance laughs out.
It takes Twilight a moment to realize what her sister-in-law is talking about, but when she does, her struggles renew. She's reminded that the other alicorn has had much longer than her to master her alicorn magic. That, and being raped tends to hinder one's magical abilities.
"W-Wait, you didn't cast the- hhng- the spell, please, pull out!" The ache is all-consuming. Her brain feels numb; she's amazed that she could get words out at all. She's convinced that she can feel her brother's cock scraping against the back of her womb with each heavy thrust inwards, though she can't remember whether he's big enough to actually do that or not. Did she used to enjoy it, if he could? Her body jerks with each pump of his hips, and she hates her body for clenching around the painfully solid length of flesh pistoning in and out of it.
All Shining Armor does is grit his teeth, snort, and pick up his pace. Distantly, he hears the melodic giggle of his beloved wife, but all he's focused on right now is cumming. One, two, three, and on the fourth thrust he buries himself to the hilt, balls drawing up tight against his body as his flare spreads wide within the smaller princess's womb. Heavy spurts of fertile semen begin to fill her, and with no way back out, he convinces himself that he can see a small bulge beginning to form in her lower belly. A low, gut-wrenching grunt exits his muzzle, and for a moment he looks shocked at the fact that such a sound left him.
"Yes, Shiny, you really did make that noise." She runs her tongue up the back of his sack before prodding playfully at his tailhole, which results in a jerk of his ballsack as another, final surprise shot of cum is forced out of him, followed almost comically by a shrill, garbled cry of "no more, please!" from Twilight.
For a few minutes, the only sound in the room is Princess Twilight's heavy, choking sobs. Her recovery isn't made any easier by the fact that her big brother - and now rapist - is laying on top of her in a position that she's all too familiar with. She cries harder, snot and tears drooling off of her face and down onto the sullied bedsheets. When one of her own hooves hits her upside the head, she realizes that she's finally been released from Cadance's magic. All she does is curl her forelegs inwards. She wishes she could become smaller.
Brother and sister float upwards, surrounded by Cadance's aura, and she gets a good look at where they're connected before deciding that she wants to keep Twilight plugged up a little bit longer. To that end, she positions them on their sides on the bed, still facing each other, before she makes herself comfortable on her own side, cuddling up behind Princess Twilight as the big spoon.
Leaning over top of Twilight's head for a brief kiss with Shining, she gives the whimpering lavender princess a kiss too, smiling fondly at the lack of response, before settling down with a content sigh. "Don't worry, Twilight. You're going to love motherhood. And if it didn't take, there's always next time, right?"
The body in-between them begins to quiver harder, her desolate mewls growing in volume briefly before she resumes near-silence.
