Vindicated Depravity

Shining Armor stretched and arched slightly with the faintest of groans, before beginning to walk down the long hallway to the rooms he and Cadance shared. He had just returned from a lunchdate with Twilight Sparkle. Over the past month, he had been trying his best to be close to his little sister again.

With the threat to the castle over, he was once again free to pursue to activities of leisure in his now-existent free time. And the first order of business was restoring the strained relationship with his little sister.

And so it was lunch dates and picnics galore, flying a kite with her, throwing a ball, helping her study, sneaking into the palace library with her (even though it was perfectly legal) to purloin books on gryphon mating habits. That last one was kinda weird, but someone had put the idea in her head, and bless her heart, Twilight was the most curious unicorn in all of Equestria.

Two hours of reading up on the magical potential of terrestrial elements and magnetic fields over cups of coffee later, and Shining Armor was starting to feel the strain in his neck.

He was looking forward to just laying himself out on the bed he and Cadance shared, and relaxing for the rest of the afternoon. Maybe even snuggle with his wife.

Shining Armor pushed open the door with a hoof, slinking inside quietly in case his wife was napping. Generally, she wouldn’t even be back in the rooms until later in the evening.

“Ah, big brother!” came the excited call from his bed.

Twilight was sitting on his bed, a hoof resting on the corner of a book to keep it held open.

“I was just hoping you’d help me do some extra studying...I’ve been doing a course on equine physiology and I don’t have any male ponies to study...” Twilight simpered, her tone undeniably seductive. She was hitting on him?!

Twilight shifted to arrange herself in a more advantageous pose, stretching out on the bed and grinning at him, arranging herself deliberately to give him the best view of her taut stomach and chest, and the way her body was curved just enough to hide her sex from his view, but providing a tantalising tease of the flesh leading down to it.

Shining Armor stood in the doorway with an open mouth, staring in utter stupefaction at the sight before him. Twilight was trying to seduce him!

It was several long seconds before Shining Armor recognized the shape of a wing on Twilight’s side. Her horn was still poking out of her purple mane, and it all crystallised in his mind in an instant.

“...Cadance?” he asked in disbeleif.

A soft giggle left the alicorn as she shook her head and waved a hoof at him in rebuke, “Nono big brother, you shouldn’t be thinking of Cadance at a time like this.”

Shining Armor stepped closer to the bed uncertainly. “C-Cadance...seriously, what are you doing?”

Cadance pouted at her husband and then shook her head, rolling her eyes. “I try to surprise you with something sweet and you always ruin it.”

“You’re...painted up like Twilight!” Shining Armor protested, waving a hoof at her accusingly.

It really was a very well done job. The wings were the only thing that gave it all away. From the specific shade of her coat, the cut of her mane, and even Twilight’s Cutie Mark.

“Oh?” Cadance asked, twisting around and lifting a hoof to rest on her flank, inspecting her paintjob. “I hadn’t noticed.”

“What are you doing?” Shining Armor asked, staring at the alicorn, not understanding at all.

“I’m trying to seduce you as Twilight. It’s a kind of roleplay,” Cadance replied flippantly, raising a brow at him with a slight giggle.

“But you’re painted up as my sister!” he rebuked, waving a hoof in her direction in mortification. “I’m not that kind of stallion!”

“Oh, you claim that,” Cadance said, watching him, looking him up and down, and then patting the bed, urging him to come lie beside her.

Shining Armor shook his head at his wife for a long moment. “I know that love is your thing...but this is crazy. I don’t feel that way for Twilight!”

“Don’t you?” Cadance asked, arching a brow upwards and shifting around to bring her nose right up in front of his own, staring into his eyes with a thoughtful expression. She smiled, and gave Shining Armor the disturbing image of his sister speaking to him in his wife’s voice, “You didn’t feel that twinge deep in your groin when you first saw me on the bed asking to ‘study’ you? Didn’t your eyes sink down my form when you first entered the room, searching to see if anything was visible...?”

Shining Armor swallowed audibly and then looked away, feeling heat rising in his cheeks. “Th-that’s immaterial...”

Cadance smiled, lifting her hooves to touch gently at his chin and pull his gaze back around to meet her own. “Shining...it’s natural to have these feelings for your younger sister.”

“Natural?” Shining Armor asked with a blank stare.

“Yes, natural,” Cadance soothed, stroking her hoof back to gently work along the side of his neck.

“But I don’t feel that way for her,” Shining Armor rebuked again.

“You keep saying that...” Cadance said with an eerie smile, leaning in and turning her head to the side, resting an ear against his chest. “And yet I can hear your heart beating faster at the thought of getting to live out a naughty fantasy with your little sister.”

“Listen to what you’re saying, Cadance!” he rebuked once more, rubbing his temple with a hoof.

“I’m saying that you have deep-seated sexual urges for your little sister, that they’re completely normal, and I think it would be fun to play into those fantasies and enjoy the fiery passion it induces in you,” Cadance responded flippantly.

Shining Armor shook his head helplessly, “You still think this is going to happen?”

“I know this is going to happen,” Cadance stated with a low purr, grinning at her husband. “I’m going to coax you until you slowly open up to the idea and then begrudgingly go along with it until you actually start to enjoy it.”

“You can say ‘I told you so’ when we’re done,” Shining Armor said calmly, before adding, “But you’re still painted up like my sister whom I have no desire for!”

“Oh you keep claiming that!” Cadance said with a pout. “I’m your wife, Shining, you can admit anything to me.”

“I can admit that I’ve never had any fantasies about my sister like that!” he rebuked firmly, bopping his wife on her painted nose.

“Maybe not consciously...” Cadance cooed, grinning up at him, her tail giving a slow, excited flick. She leaned in close to gently lap at his cheek and then whisper seductively into his ear, in a tone that was scarily like Twilight’s, “Ever found yourself staring at my rump, big brother? Ever wanted the warm touch of one of my hooves to linger at your side a little bit more? Ever had to fight the urge to lean in and kiss me when we’re close like this, big brother? huh?”

Shining Armor stared down at his wife in shock, eyes wide and breathing increasing in speed as his cheeks flushed. “This has to be some kind of joke...”

“This isn’t a joke, big brother...I need to study, and you’re the only male I can study,” she simpered, gently stroking her hooves down his neck and to his chest, kneading slowly.

“C-Cadance, this is weird,” Shining Armor protested weakly, lifting a hoof to gently stroke along her neck imploringly.

“Come now, Shining,” Cadance said shortly, in her normal tone, nudging the base of his neck with her nose. “The natural protective urge an older sibling has for their charge can easily, and quite often does, transfer over into base sexual desires. It is perfectly normal, if not stigmatized by society at large.”

“But Twilight is my sister!” Shining Armor hissed in response, staring down at his painted wife.

“And I’m not...” Cadance said in a decidedly seductive tone. “You can live out your desired on me without any actual depravity having taken place...”

“But...I...” Shining Armor tried to protest, but was silenced by his wife’s hoof on his lips.

“If you can look me in the eyes and say that there’s no sexual tension between you two, then I’ll get myself washed up and grant that changeling fantasy you’ve been trying to hide from me,” Cadance responded with a sly grin.

Shining Armor stared at his wife for a long, long moment, before deflating and staring at her, shaking his head. “I’d lie to get kinky changeling roleplaying...but you’d know I was lying.”

“Course I would, hun,” Cadance said with a smile, leaning up to kiss him. She pulled back, instantly slipping into Twilight’s voice again, “Now, I have study to do.”

Shining Armor stared down at his wife, painted up to look like his sister, and then crossed his hooves in front of himself, taking a deep, steadying breath, before nodding. “W-what do you need help with studying, Twilie?”

“I love it when you call me Twilie,” she crooned, leaning up to gently nuzzle in underneath his chin, “I need to study the anatomy of a stallion for a school project...and I figure I’ll just study you. You don’t mind, do you, big brother?”

“Not at all, Twilie, what particular things do you need to study?” he asked warmly, settling himself out a little more comfortably, watching her.

“Stallion anatomy!” she replied with a grin, leaning in to lip gently at his neck. “Like...your horn!”

Shining Armor nodded, leaning his head downwards gently to present his horn to her gaze.

Shining Armor’s faux-sister hummed happily a moment, and then peered down at her textbook, reading a few lines, before turning her gaze back up to her ‘brother’s’ horn.

“The book says that they’re really sensitive!” she said with an earnest nod, lifting a hoof to clasp around the horn and squeeze along the base of it gently. “Is it, big brother?”

Shining Armor closed an eye reflexively as he felt the hoof squeezing at his horn, and then beginning to slowly work up and down the length of the sensitive material. His breath caught in his throat, and his hindlegs squirmed a little bit against the bed at the sensations. “Y-yeah.”

A low hum left the young ‘unicorn’ and she peered up at her ‘brother’ with an innocent grin, before looking down at the textbook again, releasing his horn. “It says that in some cases, males can achieve orgasm through simple horn stimulation!”

Shining Armor’s breath caught again, and he stared down at Twilight for a long moment, blinking slowly. His voice squeaked as he asked, “W-what book are you reading?”

“Equine anatomy!” she replied with a vigorous nod, grinning and then holding up the book for him to see the cover of it.

The title ‘Equine Anatomy: A Study’ was embossed on the front cover in neat bronze lettering.

Shining Armor was suddenly impressed by the amount of trouble that his wife had gone through to make the charade as realistic as possible. He was infinitely more impressed by Cadance’s skills when he realised that he had actually forgotten, for an instant, that it wasn’t Twilight in front of him.

“Let me try!” ‘Twilight’ said with an innocent giggle, leaning up and instantly capturing his horn in her soft lips, sinking her muzzle down to the base of it with a smooth motion.

Shining Armor’s eyes widened, and he gave a shuddering gasp of surprise and delight, swallowing hard as he felt the soft tongue beginning to slowly swirl and grind around his horntip in her maw. Soft, moist walls of suckling flesh surrounded his horn, undulating slowly along the rigid length of his horn, while her tongue ground against the tip of it suggestively.

Immediately, he asked himself where his sister had learned to do such explicit things, and had to forcibly remind himself that it was his wife. And he knew where she had learned that; after all, he had been her guinea pig when she was trying new things!

“T-Twilie, h-hun, you might wanna s-stop...” Shining Armor stuttered, panting heavily, his cheeks flushed with warmth, rolling unconsciously onto his stomach to hide the swelling stallion cock beginning to make itself apparent between his legs.

“But this is fun, big brother!” ‘Twilight’ said with a giggle, pulling back and then lapping delicately along the tip of the horn, and then leaning in to give the tip of the horn a soft, delicate kiss. Her tone was soft and innocent, but utterly seductive as she murmured, seemingly to herself, “Hmm...I wonder what else I could do this to...?”

Shining Armor inhaled deeply, shuddering and squirming a little bit under the workings of his faux-sister, her words making him flush harder, feeling the length of heavy flesh against his stomach twitching with eager desire.

“Big brother...do you have any ideas?” ‘Twilight’ asked, raising a brow at him and gently lapping at the tip of his horn still, delicately running her tongue over the tip.

Shining Armor splayed his ears back, his spine arching a little bit as he tried his best not to grind himself against the bed. “I-I have no idea, Twilie.”

“Are you suuuure?” faux-Twilight asked, pulling back and peering into his eyes for a long, long moment. “You know you couuuld never lie to me, big brother. I know there’s something you could show me that isn’t in the books...That’s why you’re the best for studying with! You teach me things that aren’t in the books!”

Shining Armor stared down at his simpering faux-sister, hearing his heart pounding in his ears. He’d already had Cadance’s muzzle in his lap countless times before, but somehow, this was different. The thought of suggesting that she put her muzzle to use on his aching stallionhood was making his breath come shallow and his heart beat faster, as though it was the first time. It was so damn naughty!

“W-well...I-I...uhm...m-maybe...” Shining Armor tried to stutter out an answer to his faux-sister, thinking how to phrase it so as not to be offensive.

Cadance took it into her own hooves though, shifting to peer past his shoulder, her eyes widening, a hoof coming up to her muzzle. “B-big brother, is that what I think it is?”

Shining Armor’s eyes widened, and he twisted slightly to peer at himself, realising that the throbbing eager tip of his member was visible, a mottled brown against his white hide.

Swallowing down the urge to deny it all and just hide it, Shining Armor gently rolled over onto his side, stretching out languidly, revealing the length of his body to his faux-sisters gaze.

‘Twilight’s’ eyes widened a little bit, and she stared for a long moment, entranced, leaning in close to the length of stiffened stallionhood, a hoof lifting tentatively. “C-can I touch it big brother?”

Shining Armor closed his eyes and took a deep breath in, and then out, shuddering faintly. “Y-yes, Twilie...you may.”

A low purr left the ‘unicorn’ and she lifted a hoof to wrap around the base of the thick length of flesh, squeezing gently at it, gazing at the stallionhood appraisingly. “It’s so warm...and heavy. It’s even bigger than in the books!”

“Y-you’ve read a lot of books on this subject, Twilie?” Shining Armor asked, panting down at her, eyes still closed.

“Tons and tons!” came the immediate response, before a devilish smile crossed her muzzle. “I didn’t think it would be this long, big brother...I always thought it would be just long enough to touch the back of my throat but no longer...”

“W-what are you saying, Twilie?” Shining Armor asked, and then gasped as he felt a velvet tongue swipe across the tip of his eager member, cleaning up the dribble of precum there.

“Welllll...” ‘Twilight’ trailed off for a moment, staring up at him, giving a naughty grin. “Sometimes, when it’s really...really late...”

Shining Armor raised a brow, panting down at her, waiting for her to continue her story.

“I fantasize, big brother...dream of big stallion phallus’...” ‘Twilight’ whispered, staring up at him, giving the tip of his member another delicate lick. “Hot, drooling stallion penii I can stuff into my maw. It makes so wet, big brother. I swear I can almost taste them. Sometimes, I even practise on carrots while I’m rubbing a hoof between my hindlegs.”

Shining Armor shuddered and gasped at the imagery, the little lick to the throbbing tip of his aching member making him quiver helplessly as he stared down at the sight of his own sister lapping at him, and saying the dirtiest things!

“I-It’s so arousing, Shining...The book tells me that it flares up when you’re going to ejaculate!” ‘Twilight’ nodded earnestly, inadvertently rubbing her nose against his drooling tip. “Please, big brother, tell me that it’ll flare! I wanna feel your glans flaring against my tongue and shooting warm ejaculate across my palate!”

“O-Oh sweet Celestia!” The stallion inhaled hard, his eyes closing to try and block out the image of his little sister so eagerly inquiring about his orgasm, his hooves automatically gripping the blankets underneath him. The length of stallion cock throbbed eagerly as Shining Armor’s arousal went through the roof, and ‘Twilight’ took the opportunity without hesitation.

Shining Armor cried out in surprise as he felt a hot, moist mouth sinking down his member. Soft lips, a warm, velvet tongue, and the ridged top of her mouth all conspired to send him cross-eyed, his back arching and horn beginning to glow as his mouth parted in a low groan.

‘Twilight’s’ tongue began to swirl along the underside of the tip of his cock, even as she ground her muzzle deeper over his member, her hooves lifting to softly cradle his balls and squeeze the base of his stallionhood. She began to slowly tilt her head from side-to-side, causing all of the flesh surrounding his member to shift and squeeze, causing a delightful friction that was rapidly ramping up his arousal.

Shining Armor gasped and arched his back helplessly, his hips automatically trying to grind towards the skilled touches around his eager flesh, his ears pinning back as he curled to peer down at his wife.

With her paint, and her mane done up like that, she looked so much like Twilight that it was almost scary. There was, of course, the size difference, and the wings. But when he was staring down at her like that, her eyes closed in concentration, nursing at his throbbing member like a foal at a teat, it was Twilight.

And then her eyes opened, purple irises staring up at him imploringly, while she smiled around his eager member. Shining Armor stared down at his sister suckling around his cock so eagerly, and he just lost it.

‘Twilight’ drew back with a gasp as she felt the thick tip of the cock flare in her muzzle, stretching her jaws around it as it began to throb and jerk wantonly.

“Yes, big brother! It flared!” she squealed eagerly, lapping fervently at the tip of the flared cock again and again, parting her maw to present her open mouth and soft tongue to the tip of his stallionhood. “Ejaculate for me, big brother! Spill all that gooey semen into my muzzle!”

Shining Armor’s hips jerked of their own accord as a magical touch squeezed and jerked around the base of his member, and then he just exploded. Magical light glowed deep in his horn in a pulsing rhythm to match the pulse of blood in his stiffening member, and the pulses of gooey semen bursting from the tip.

The first thick volley splashed across her face with its intensity, splattering across her forehead and trailing down across her muzzle and nose, messing up the base of her horn. The second and third jet spilled direction into her mouth, quickly coating her tongue and drooling over it in a sticky, gooey mess. A low groan left the ‘unicorn’ as she quickly fastened her mouth over the tip of the swollen flare, her eyes widening with each sticky pulse of ejaculate that was fired into her maw over and over again.

Shining Armor groaned and shuddered, quivering and arching through the most intense orgasm of his life, feeling the heavy bursts of his spunk firing into his sister’s muzzle over and over again, until he just slumped to the bed with a low groan of delight.

A prod of a hoof against his shoulder made him blearily blink an eye open to peer down at her.

A grin crossed the female’s maw, and she paused for effect, before opening her mouth up innocently, poking out her tongue. Voluminous amounts of white, gooey spunk spilled from her mouth to drool slowly to the bed, while a thick reservoir of the potent stallion essence was still held inside. Grinning, she closed her mouth, and then tilted her head back, swallowing, and then opening up again to show him it was all clean.

Shining Armor realised that if he hadn’t just filled her muzzle with the mess she was presenting to him, then he would have pounced on her and rutted her into the bed. As it was, he could barely move. It was hard to even keep his eyes open.

“I didn’t think it would be that good, big brother! You should have let me do this to you much, much earlier!”

The mimicry of his sister was the last thing Shining Armor heard before he passed out.

Consciousness returned slowly to the unicorn, and he mumbled something unintelligible before he opened his eyes, peering down at his wife, who was snuggled up against his side, looking very much like herself.

“Oh that was a weird dream,” he stated, rubbing a hoof against his forehead.

“A dream, big brother?” Cadance teased, kissing his cheek.

Shining Armor went still a moment, quivering in mortification. “I-It was real?”

“Well...as real as your wife getting painted up like your little sister and seducing you can be. I take it you enjoyed it?” Cadance asked casually.

“It was weird.” The unicorn huffed faintly, waving a hoof for punctuation.

“And yet you came so hard that, for the first time since I’ve known you, you couldn’t muster the stamina to get yourself up and please me in return,” Cadance replied accusingly.

“I’ll make it up to you,” Shining Armor replied, wrapping a hoof around his alicorn and pulling her against his side. “But, I have to ask...why?”

“Why? Because you have sexual urges for your sister that both of you are far too shy to get out in the open,” Cadance said with a calm wave of a hoof.

Shining Armor huffed and nuzzled into his wife’s neck gently, “But she’s my sister, that’s why.”

“It’s unhealthy to be lusting after something you can’t have,” Cadance said with a warm smile, nuzzling into his cheek in response with a happy hum.

“It’s unhealthy to want to mate my sister, you mean?” He asked, raising a brow.

“Dearheart,” Cadance said, petting his cheek lightly with a hoof, “You’re married to the princess of love. You’re going to have to stop treating base desires like some taboo thing I have no clue about. I think it would be very unhealthy for you to be so close to your little sister and not feel any inkling of sexual urges for her at all. After all, it is stallion nature.”

“It’s still a pretty hard pill to swallow,” Shining Armor responded, frowning deeply and working his hooves against the covers slowly.

“You think pills are hard to swallow?” Cadance rebuked suggestively, raising a brow at him.

Shining Armor rolled his eyes. “You know what I mean.”

“Hey. I’m not the one who wants to bone my little sis’, you pervert,” Cadance said with a grin, kissing the side of his muzzle.

“I love you, my kinky alicorn,” Shining Armor said, leaning in to pull his wife into a kiss, humming happily.

“I love you too, my depraved unicorn. Now...admit to me that you desire your little sister in far more than a platonic fashion, so I can prey on your desires to sate my sexual deviances,” Cadance said with a wave of a hoof, grinning.

Shining Armor licked his lips for a moment, nervous, and then shook his head, before stating calmly, “I have no sexual desire for my sibling, whatsoever.”

Cadance rolled her eyes, shaking her head and then nosing into his neck gently.

The stallion peered down at his wife, gently rubbing his nose against her cheek, and then added; “For now. Maybe...next week you’ll have wheedled me out of my shame spiral enough for me to try it again.”

A grin spread across the alicorn’s cheeks, and she didn’t even look up at him as she murmured into his neck, “I told you so.”

Tentative Depravity

‘Twilight’ groaned and shuddered under the constant barrage of Shining Armor’s thrusts, her chest and face pushed into the pillows repeatedly. Sweat matted both of their coats, and a slick dribble of sexual fluids was spilling from around Shining’s embedded cock, seeping from within the clenching cunt of his little sister.

‘Twilight’ groaned faintly, biting down on the pillow to try and stifle her noises as each rocking thrust from Shining Armor drove deep inside her, filling her utterly with his thick, round cock. Her wings fluttered in reflexive spasms, and her rump lifted as high as it could, giving the best angle she could afford to her husband’s motions.

The paint that Cadance was wearing smudged faintly from their sweat and the delicious friction between them, causing Shining’s pristine white coat to become smudged with purple.

A constant stream of encouragement left the alicorn, her panting supplications occasionally halting from a particularly brutal, liberating thrust. “Y-yes big brother! H-harder! I can take it! I’m a big mare now!”

Shining Armor growled and gripped his ‘sister’ tighter, hooves clasping around her middle, helping to hold her in place against the constant rocking motion of his eager thrusts. “G-getting close, T-Twilie,” he panted into her ear, before biting down on it lustfully, braying an eager snort of exhale into her mane.

“Yesss...” Cadance breathed, her ears pinning back a little bit as she squirmed at the dominant bite. Her muzzle parted and tongue lolled free as she was fucked so hard, another orgasm overcoming her, causing rippling spasms of delightful milking motions to squeeze and clench at the thrusting member. “C-cum in me, big brother!” Cadance cried out lustfully, “S-spill it all deep inside!”

Shining Armor growled heatedly against his ‘sister’s’ neck, burying his muzzle against her, hooves gripping her all the tighter as he drove himself into her over and over again, rocking her form back and forth even with the tight grip to hold her steady.

With an eager growl, and a few rough, almost violent strokes, the tip of Shining’s cock flared within his ‘sister’, stretching the soft, moist inner flesh around the swelling cock. Rapid throbs pulsed through the thick member, making the stallion’s motions grow jerky and rougher. With just a few quick tugs, the length of swollen flesh tensed within her, stiffening and jerking rapidly. Repeated gooey bursts of thick semen splashed across her inner flesh, painting it with the heavy bursts of cum, drenching the moist inner flesh with the sticky loads. Shining Armor snarled in delight, holding himself deep inside, flared tip pressed against her very deepest barrier, each fresh spurt of his urgent spunk dashing against her deepest reaches over and over again.

Cadance tensed up, her back arching and wings fluttering on reflex, stiffening and quivering repeatedly. The alicorn’s insides clenched around the spurting cock, squeezing and embracing it in a vice-like grip of milking, rhythmically convulsing flesh eager to coax out every last dribble of his spunk.

The stallion gave a low groan and collapsed atop his ‘sister’, panting hard and shifting weak hooves to hold around her middle, burying his nose in her mane with a low groan. “Oh sweet Celestia, Twilie. That was good.”

Cadance panted up at her husband, a goofy grin plastered across her features, wings slowly lowering, resting on the blankets. “That was gooood big brother,” she murmured, in the perfect mimicry of Twilight.

Shining Armor looked down into the doppelganger of his little sister and leaned in to kiss at the base of her horn, grinning. “I love you, Twilie.”

The two ponies stared into each others eyes for several long moments.

A prickly sensation rolled across the back of Shining Armor’s neck, and he blinked once, looking up.

Twilight Sparkle stood in the doorway, one hoof on the door itself, eyes wide and mouth open, a picnic basket levitating beside her. Somewhere in the back of his mind, Shining Armor remembered that he had meant to take Twilight on a picnic that afternoon, and she must have come looking for him.

The forefront of Shining Armor’s mind however, was focused on the fact that his slowly-leaking spunk was drooling from his wife’s cunt, who was painted up to look like his little sister, who was standing in the doorway!

“T-this isn’t what it looks like,” Shining Armor stuttered, fumbling over the words in a mix of anxiousness, fear, and post-fuck-session bliss; a bliss that he was quickly coming out of as he realised that Twilight Sparkle was standing in the doorway! Who knew how long she had been there?!

Cadance blinked and lowered her gaze from her husband eyes, following his line of sight to where Twilight stood in the doorway, aghast, watching them both.

A long, awkward silence stretched between them. The silence was broken as Twilight turned away from them and bolted down the hallway, the picnic basket falling with a clatter to the floor.

In mere seconds, Shining Armor was following after her, slipping out the door with a call of, “Twilie, wait!”

Twilight was already halfway down the hall when Shining Armor made it to do the doorway, and he had a glimpse of her rump disappearing around a turn and her tail flicking out of sight.

Shining Armor bounded down the hallway, but by the time he got to the corner, Twilight had already disappeared.

Shining Armor shifted his hooves uncertainly, his head lowered and eyes on the ground in front of him as he walked. It was a few days after Twilight had seen he and Cadance together like that, and he hadn’t heard a word from his sister. He had sent a letter to her, imploring her to speak to him, but it had gone unanswered.

It was one of Shining’s rare weekends off, and he was supposed to be taking Twilight out for another picnic. It would be the first time he had seen his little sister since she had caught him and his wife in such a compromising position. He fully expected Twilight to stand him up.

To his surprise, however, Twilight was standing where Shining was supposed to pick her up; in front of Sugar Cube Corner. She had a bag over her cutie mark, and a basket was levitating in front of her.

“Hello,” Twillight said with a wave of a hoof.

“Uh... Hi Twilie,” Shining Armor said nervously. “Ready for the picnic?”

Twilight lifted up the picnic basket, jiggling it a moment. “I see you’re as observant as ever.”

Shining gave a weak laugh and shook his head. “Well c’mon then, Twilie,” he said, as he turned and started back up the path towards Canterlot, heading for their favorite picnic spot.

It was a quiet walk, and they didn’t talk at all. Shining Armor wasn’t sure what to say to her. Maybe she didn’t even get a really good look at what he and Cadance had been doing?

“So uh... about last week,” Shining nervously said, rubbing a hoof against the back of his neck.

“Yes?” Twilight asked blankly.

“Sorry about not picking you up, something uhh... came up,” Shining replied lamely, his ears splaying.

“You refer, of course, to your penis?” Twilight replied flatly.

Shining spluttered at that, and Twilight just gave a smug snort before walking ahead of him in triumph.

This put shining in a rather interesting position in relation to her, and he found his eyes lingering on her rump and the swaying purple tail. His cheeks flushed just faintly with blood, and he shook his head rapidly to clear it of the depraved images suddenly springing into his mind.

“Th-that wasn’t it at all!” Shining protested, bounding forwards to catch up with his little sister, so that he didn’t have the tempting view of her rump in front of him.

“Oh? So that wasn’t you I saw atop Cadance in the castle when you were supposed to be picking me up?” Twilight asked calmly, raising a brow at her brother. “If not, then perhaps you should ask her who she is cheating on you with.”

“I... Just... But...” Shining Armor spluttered, unable to respond, thinking furiously.

Twilight lifted a hoof to rest on her brother’s lips, keeping him quiet. “Shine, you’re a stallion. Stallion’s have needs. Your wife is a full-grown mare. She has needs too. I’d just rather you told me before you ditched our picnic to mate with your wife.”

“It wasn’t like that, Twilie,” Shining protested urgently. “She kinda jumped me.”

Twilight gave a giggle at that, “Cadance is the alicorn of love. Lust is part and parcel of love... It’s only natural that she'd want to do that with you.”

“I know, but I still feel bad... I should’ve sent word that I wouldn’t be arriving. It just kinda... slipped my mind,” Shining Armor said ruefully, ears splaying back.

A faint pink tinge marked Twilight’s cheeks as she looked back over her shoulder at her brother. “S-shine... Why was Cadance painted purple...?”

Shining Armor’s heart began to pound faster, and his mouth went dry. “W-well, s-see, she just wanted to uhm... Try out a different c-colour scheme...”

Twilight shook her head, lifting a hoof to halt her brother’s words. “Y-you called her T-Twilie.”

Shining’s stuttered at the blunt accusation, his ears pinning back flat against his skull. After a few moments, he fell silent, looking down at his forehooves in shame.

Sensing movement in front of him, Shining Armor looked up. His mouth fell open, and his eyes widened.

Twilight was bent over, chest to the ground and rump in the air, her tail twitched to one side, exposing everything to him.

Shining Armor closed his mouth and swallowed hard, his eyes automatically drawn to the sight of his sister’s cunt bared so willingly to his gaze. The soft purple fur that covered her form was visible between her thighs, leading up to the soft, pliable outer lips of her sex. Her position was causing a slight strain on her flesh, causing the outer lips of her cunt to spread slightly, revealing the tinge of pink hidden between them. His heart thudded violently in his throat as he stared at this wondrous sight.

Twilight wiggled her rump back and forth for a moment, looking back over her shoulder, eyes narrowed, as she whispered, “And do a little shake...”

Shining Armor swallowed once more, and then looked away pointedly, his cheeks flushed deeply with pink, tail twitching back and forth behind him in reflexive spasms. He added up columns of numbers in his head, trying to concentrate on something other than the sight of his sister’s luscious cunt so close in front of him. It was all in an effort to keep the swelling between his legs from taking place. That would be impossible to explain away.

“I remember you always loved to watch me when I did that...” Twilight breathed, straightening up and turning to face her brother, her head tilting slightly to the side and ears pricking upwards. “...You’re... You’re attracted to me, aren’t you, Shine?”

“T-Twilie, I,” Shining started to say, shaking his head firmly and refusing to look up, aware of the warmth in his cheeks.

Twilight snorted once, lifting a hoof to halt his words. “Don’t lie to me, brother.”

Shining Armor winced at her tone, and then hung his head. “I... Yes,” he admitted, with painful honesty. “I am.”

By the time Shining Armor looked up again, Twilight was already long gone, disappearing down the path and away from her lecherous brother.

Prorated Depravity

Twilight Sparkle’s heart beat somewhere at the base of her throat. Her throat was constricted, and she found it hard to breath. The shocking ramifications of her very own brother’s admission rocked her. She could hardly believe it!

Of course, seeing him atop Cadance, and seeing Cadance painted up like herself, Twilight had put two and two together. But there was just something that was utterly more stunning and forceful about hearing it from her brother’s own mouth!

Twilight had watched carefully when she bent over in front of him. She had watched the way Shining’s eyes had been drawn straight to that naughty area between her legs. She had seen his cheeks flush with embarrassment at her accusation, and she had seen, with her own eyes, the effect that it had had on him: the swelling of his thick sheath as it tried to contain the eager stallion cock straining to get free.

Of course, Twilight had seen her brother’s cock before. Growing up together, it had been almost impossible not to. She still remembered the first time; catching him looking at a magazine, holding it in front of himself with his hooves while his magic rapidly stroked at his stiffened cock.

It was an image that Twilight doubted she would ever forget, watching her brother tense and shudder, his thick cock stiffening and throbbing madly as it began to pump spurt after spurt of a gooey white substance across the floor. She had been too young at the time to really understand what was happening.

And then there were the times when Twilight was with her big brother, that she caught him staring at her. She didn’t say anything about it, but she knew he liked watching her.

Twilight strode down the path, trying to push the thoughts from her mind. With a growl of annoyance, she sidestepped off the path and headed for the nearby lake. A touch of magic pulled her bag off, and she set down the basket, before unceremoniously throwing herself into the water.

The shock of cool water against Twilight’s face and body was just what she needed; a refreshing awakener that flushed the thoughts of her brother from her mind.

coming up for air, the unicorn gasped, paddling back to the shore and just resting there, laying her head on her hooves, her mouth and nose just above the surface of the cool water.

Once more, Twilight’s thoughts turned to Shining, and the revelation that he was sexually attracted to her. He wanted to fuck her?

Twilight tried to wrap her mind around it. Her own brother, wanting to fuck her. How did he think that would even work? How would her brother brooch a subject like that? It was so awkward a subject. Would he just brooch it to her on one of their picnics? ‘Oh hey, Twilie. I wanna fuck you. You game?’?

Even in her mind, it sounded stupid. And he had been fucking Cadance, pretending that it was her! How could her own brother do such a thing? What did he imagine? Twilight felt dirty just thinking it!

Did he go down on Cadance? Did he lave his tongue against that tight pink cunt while imagining it was his very own sister that he was tonguing? Did he get Cadance to go down on him in return and pretend that it was his little Twilie who was sucking on that thick stallionhood?

Twilight wrinkled her nose in disgust, giving a faint grunt and rolling over onto her back, staring up at the sky, watching a cloud scudding towards the horizon in the west.

What kinds of terrible fantasies did he have of her? Did he watch her sleep? Did he jack off while imagining her? Or even watching her?

Twilight cast her mind back to a few years previously, just before her brother had moved out of their home. It had been late at night, and she had awoken to find her brother in her doorway. She hadn’t realised it at the time, but she had been sleeping in a provocative position, on her back with her legs splayed out. She had been completely exposed. Her brother would only have to glance in to see everything. It wasn’t so big a deal, considering that Canterlot and Ponyville ponies didn’t wear clothes as much as other towns. But still!

Had he been masturbating while watching her? Secretly using his magic to squeeze and stroke at his stiff stallionhood while he stared lecherously at his little sister exposed like that? What perverse thoughts were going through his mind while he stared at her?

Twilight entertained the idea for a moment, of her own brother, smiling up at her from between her thighs, light blue eyes staring into her own as his nose touched delicately against her burning cunt.

A soft groan left the unicorn, and she squirmed slightly, her eyes widening as she realised that a hoof had sunk down between her legs sometime during her imagining. Automatically, she was rubbing the hoof against her cunt, working back and forth slowly to stimulate her senses.

Twilight bit her lower lip, hindlegs tensing up a little bit as she cast a furtive glance left and then right, confirming that she was alone, before she closed her eyes and returned to her imagining. Her hoof pressed against her cunt all the more eagerly, working slowly at the soft, pliable outer lips, stretching them and pressing her open a little bit so she could get at her clitoris. She knew exactly how to pleasure herself, having read a few books on the subject. Books that now were hidden underneath her bed.

As her hoof ground against her clit, Twilight bit her bottom lip once more, resuming the fantasy. Would that be what he started with? Burying his muzzle between her legs and lapping at her cunt, spreading her eager sex open with his hooves and slipping his tongue up into her body...

Twilight stiffened slightly, hindlegs kicking once more and she shuddered, her rump wiggling against the soft silt of the lake bed as that magical place between her legs grew warmer.

What would he do after he was finished tonguing her? Would he make her cum, or would he leave her on edge and wanting him? Wait right before she came, and then pull back, so that she needed him? So that she was basically drooling and clenching in her need for his cock. So that when he rolled over and splayed out on his side, stretching out to expose himself to her, she wouldn’t be able to do anything but pounce on him?

Twilight swore she could feel his hot cock against her hooves, could feel it swelling against her as she coaxed it out of her brother’s thick sheath. Is that what he fantasized about? His little sister urging out his arousal? Or did it go further?

Twilight peeked her eyes open again to look about, making sure she was still alone, before continuing.

Did he imagine her using her mouth to worship that thick, mottled stallionhood? How would she even do it? Would it already be hard, or would she have to coax it out? Maybe she’d have to tease him a little to make sure that he was already half-erect before she went down to finish the job with her maw?

Twilight entertained that idea for a long moment, eagerly rubbing her hoof against her cunt in both her fantasies and in reality. But in her fantasies, she wasn’t half-submerged in a lake, she was sitting on the edge of a bed, hindlegs splayed wide and hoof rubbing delicately at the soft outer lips of her cunt, deliberately spreading them to show her brother the juicy pink insides. The young mare ground her hips towards the motions of her hoof as she imagined the look on her brother’s face, the shock and awe. The light-blue eyes narrowing as he fixated on the view of her heated cunt being spread and exposed right in front of him.

Twilight stiffened up slightly, stifling a gasp with her free hoof and grinding her other between her legs all the more eagerly, feeling her insides clenching around a phantom object as her slick liquids dribbled from her depths.

What would she do then? How would she tease him after that?

Sunshine, sunshine,

Twilight breathed the start of the childish rhyme to herself, in both reality and her depraved fantasy, covering her moist cunt with both hooves to hide the view from her brother.

Ladybugs awake!

Twilight lifted her hooves away from her cunt with a coquettish grin at her sibling, eyes narrowing eagerly at him, watching the way his eyes were drawn to her aching cunt.

Clop your hooves...

With a decadent grin, Twilight lifted her hooves to her maw, slowly laving her tongue across them and tasting her own liquids directly in her brother’s view, watching him the entire time.

...And do a little shake!

And then Twilight quickly swivelled around, presenting her rump to her brother and lifting it into the air, wiggling it from side to side, giving him the perfect view of her exposed cunt, hidden amongst the purple of her form.

Twilight groaned and stiffened, rubbing her hoof against her cunt all the more eagerly, hindlegs kicking anxiously as she approached orgasm, imagining Shining Armor losing control and just leaping on her, pinning her to the bed and thrusting inch after inch of stiff, eager stallion cock deep inside her.

The young unicorn’s depths tightened up, clenching and convulsing in reflexive spasms as they tried to milk a non-existent cock of its load to empty into her womb. Hot slicks of her liquids spilled into the cool water as she arched and quivered, grinding her hips into her hoof all the more urgently as she imagined Shining thrusting into her with a wild, primal urgency.

Twilight clenched and convulsed several times, biting down on her hoof to keep from squealing out at her legs shook and her entire form trembled, a muffled cry of delight leaving her as her eyes rolled back, glorious climax shattering her coherent thoughts.

After several long moments filled with panting and head-spinning euphoria, Twilight Sparkle came back to earth, groaning faintly and slowly stirring, weakly lifting a hoof to push her moist mane out of her face.

It was several more moments before Twilight realised that she just masturbated while thinking about her brother!

Twilight felt dirty, and ashamed. Weak-limbed and shake, she pulled herself out of the lake and retrieved her things, before heading back down the path towards Ponyville.

Shining Armor panted heavily, before just collapsing onto his side with a low, stifled groan, careful not to fall in the ribbons of gooey white spunk he had just finished depositing over the undergrowth.

He had just watched his little sister masturbating. And he had enjoyed it. It had been impossible for him not to just masturbate furiously as he watched her using her hooves to pleasure herself.

Shining had gone after her to try and explain; to somehow make it all right. But instead, he had committed more depravity.

Twilight sat on her bed in the library, head resting on her forehooves, reading a book that floated in front of her magically. Her thoughts kept straying to Shining Armor. And occasionally, those thoughts turned naughty.

Hardly able to believe what she was doing, Twilight pulled out a roll of parchment and a quill from her bedside dresser. She checked to make sure that Spike was soundly asleep still, and then wrote her letter.

The words were messy from her nervousness, and she couldn’t believe that such a simple invitation was so hard for her to write.

Dear Shining Armor

Can you please join me for a picnic tomorrow? I will meet you in Canterlot.

Please reply

Twilight Sparkle

The reason Twilight was so nervous about the invitation though, was because she didn’t intend for it to be just a picnic.

Twilight Sparkle was fully intending to seduce Shining Armor.

Iniquitous Depravity

Twilight was late.

Or, more accurately, Twilight was deliberately late. Rather than meeting her brother at the point they had agreed upon, she was instead loitering behind a line of buildings, pacing back and forth nervously.

Every now and again, Twilight would self-consciously lift a hoof to straighten her mane, or fluff her tail, or make sure that her fur was slicked down uni-directionally.

Twilight was mildly tired, having stayed up later than usual doing some very naughty things. That is to say she snuck downstairs in the middle of the night to get far enough away from Spike that she wouldn’t be caught, and then furiously masturbated to the anticapatory fantasies of what she was intending to do to her brother.

But fantasy was a far cry from reality, and Twilight doubted she had the nerve to actually go through with it all. Fantasy was fine. Fantasy was hot, but this was her brother. Was she really intending to seduce him?

Biting her bottom lip, Twilight paced back and forth a few more times, before taking a deep breath and stalking around the line of buildings towards where she was to meet Shining Armor. She was half-hoping that he had given up waiting and already left, but when she rounded the corner, she saw him sitting there, waiting, a basket on the ground in front of him.

Twilight waved a hoof nervously as Shining Armor looked up. Her brother smiled and waved a hoof in return. “Twilie! I was beginning to think you weren’t coming.”

Twilight gave a nervous laugh at that, nodding slightly and stepping over closer to her brother. “Well... I was just... you know. Busy.” She gave a weak laugh and tried to look innocent.

Shining Armor nodded gently, and rose to his hooves, levitating the basket to chest height. “Do you have anywhere in particular in mind?”

Humming faintly, Twilight leaned in towards the basket, inhaling. In passing, she got a strong whiff of her brother’s scent. “Something smells nice,” Twilight purred, realising after she said it that she wasn’t just referring to the scent of bread coming from the basket.

“Cadance baked them herself,” Shining Armor said with a smile.

Twilight smiled at that, and then jerked her head down the mountainside. “There’s a quiet little lagoon along the river that I wouldn’t mind having a picnic at.”

Shining Armor nodded gently, sliding into place beside her. “Lead the way,” he said with a gentle nod.

Twilight smiled in response, turning about and beginning to walk down the path, leading her brother towards their intended picnic spot.

Twilight had almost given up on the stupid idea of seducing her brother. What was she thinking? It was a great fantasy for a masturbation aid, but in reality it was a stupid, stupid thing to attempt.

That was, until Twilight realised that she was walking in front of Shining Armor at just the right angle. When she looked back over her shoulder at him, she caught him staring sideways under her tail, watching her rump. With a little flick of her tail, seemingly innocently, she flashed him a view of her cunt, and was so inexplicably gratified by the flush of warmth that suddenly filled his cheeks as he averted his gaze nervously.

Shining Armor wanted her. Twilight could tell.

After a few minutes walk, they made it to the lagoon, a gently swirling pool of water with the lake feeding into it, and then feeding out on the opposite side. Twilight sauntered over to a patch of grass, and laid herself out on it happily, resting her head on her hooves. The entire area was screened from view by a thick stand of trees in all directions. Anypony would have to walk within a stones throw of the clearing to even see what was happening within. It was the definition of private.

Shining Armor moved toward his sister, setting the basket down in front of her, and then levitating the blanket from on top of it, spreading it out before laying on top of it carefully. “I wish I had your fur,” he stated, jealousy in his tone.

“My... fur?” Twilight asked uncertainly.

Shining Armor nodded firmly. “Indeed, Twilie. It’s a lovely colour, and it’s not stark white,” he said with a soft laugh, brushing his chest with a hoof. “My fur dirties so easily.”

“But white is a very regal colour,” Twilight said with a gentle nod, scooching forwards to open up the picnic basket. She looked up for a moment, regarding her brother, “...It looks good on you.”

“You look good too, sis,” Shining Armor said with a little bit of a smile, before motioning with a hoof. “Cadance said I was forbidden to eat any of the loaves until the picnic started, so I’m starving.”

Twilight grinned at that, picking up one of the loaves and pressing her nose close, inhaling the scent of it. It was a golden-brown colour, perfectly baked, and sprinkled with cinnamon. They smelled delicious.

Without hesitation, Twilight popped the pastry into her mouth and chewed it up happily. Shining Armor leaned in to do the same, selecting one of the larger pastries and downing it in two quick, neat bites.

The two ponies exchanged pleasantries as they made short work of Cadance’s treats. But Twilight was having increasing troubles keeping her mind away from naughty thoughts. She had decided to simply enjoy the picnic with her brother, but now... she wanted nothing more than to seduce him, to feel that thick cock sinking into her body. She could feel her pussy beginning to warm and moisten, the soft outer lips, covered in the soft plush fur, swelling and flushing with blood with her arousal, revealing the shiny pink inner depths.

Shining Armor seemed to be thinking along the same lines as well, as she caught him staring at her with an eager look in his eyes, and he had rolled carefully over onto his stomach, perhaps to hide a certain swelling.

Twilight entertained the fantasy that he was hiding his swelling cock from her view, thinking lewd things about her. Twilight tried to force herself to think of something else, as she could already feel a dribble of her moisture slowly tracing down over her clit to drip off onto the grass below. Her inner muscles clenched on reflex, yearning for something inside them.

Neither of the siblings saw the pink heart float gracefully over top of them, and then shatter. Twilight blinked. Shining Armor lifted his head.

Casting a furtive glance left and right, Twilight rolled over onto her rump, her cheeks flushing deeply as she deliberately splayed her hindlegs, exposing herself to her brother. One hoof slid back behind her to support her weight, while the other hoof pressed down to eagerly begin rubbing between her legs, grinding against her already-slick cunt.

“S-Shining, I want you,” Twilight breathed, her eyes half-lidded, and her tone at once seductive, eager, and tentative. Her hoof ground firmly against her heated folds, in full view of the wide-eyed stallion. “I’ve been sneaking downstairs in the library just so I can hoof myself silly fantasizing about you fucking me. You want me, don’t you, Shining?”

Shining Armor swallowed hard, watching with wide eyes as his own sister rubbed a hoof against her quite visibly dripping pussy so very, very close to him. He tried so very hard to maintain eye contact with her, to pay attention to what she was saying, but his eyes were dragged down to stare at what she was doing to herself. He was forced to stare at what he had only fantasized about before: the hot pink folds of his sister’s cunt so willingly bared to him.

Twilight whimpered faintly, rubbing her hoof against herself all the harder, biting her bottom lip, eyes sliding closed as she began to vigorously rub her hoof against herself, quickly getting it slick with the drooling liquids. Another soft whimper left her muzzle, mingled in with the soft, needy exhale of ‘Shiiining...’

The stallion watched with narrowed eyes, panting faintly already. With a shudder, he rolled over onto his side, facing her still, watching intently as she worked at herself, even as he exposed himself to her in turn. His own arousal was becoming evident, in the growing of the mottle white-and-grey-speckled cock stiffening between his hindlegs.

Twilight peeked one eye open and gasped, her hoof beginning to rub at herself all the more intently, awed at the size of the growing stallion cock. “O-oh sweet Celestia... I can’t wait to feel that inside me...”

Shining Armor shuddered a little bit more, his ears pinning back as he watched his very own sister masturbating in front of him. It was impossible for him not to become aroused at the sight. Chewing his tongue a moment, he stretched out, his horn beginning to glow. A blue glow encompassed his member, and began to rapidly, eagerly move up and down it, working the stiffening cock. The stallion groaned faintly, his nostrils flaring as the aroused scent of his sister so close began to invade his senses, muddling his mind even further.

Whimpering in delight, Twilight watched with unguarded interest as her brother worked himself off with his magic right in front of her. Her eyes traced down the form of his stiffened cock, admiring the soft curves and the supple bend to it, watching it throb faintly in time with the stallion’s powerful heartbeat. A single bead of precum drooled from the tip of the rigid length, and Twilight groaned softly, licking her lips, grinding her hoof against herself all the harder as she watched.

Twilight bit her bottom lip until she almost broke the flesh, whimpering and panting in delight, her chest heaving, hoof grinding all the more firmly against her aching, quivering cunt in repeated motions. Her hindlegs quivered and kicked reflexively, and her limbs got shaky as she clenched her eyes closed and humped towards her hoof a few times, slick cunny squeezing around a non-existant object. A stifled cry left the unicorn as she quivered, tensing up as orgasm crashed over her body, a slick burst of her liquids drooling from her spasming cunt to wet the blanket between her legs.

Panting and pink-faced, Twilight slowly relaxed a little bit, slowly lifting her hoof to her muzzle. She inhaled her own heady scent, hoof shaking tentatively, before she took a deep, fortifying breath and pressed her nose in to begin slowly, seductively licking her hoof clean.

Shining Armor watched all this with wide eyes, his own form beginning to tense, his hips shifting into the magical squeezing around his eager cock. The tip of it was beginning to flare with the stallion’s impending climax, his arousal skyrocketing at his little sister’s seductive display.

Twilight panted softly, watching with narrowed eyes as her brother magically jerked himself off right in front of her. With a soft groan, she pushed herself forwards, dropping down onto her chest and stomach and crawling close to the stallion. Her nose was mere inches from his swollen cocktip as she watched him, giving a low groan at the musky scent of her sexy brother so close.

“S-shining, stop!” Twilight breathed, placing a hoof on his stomach to get his attention.

Shining Armor gave a low groan of frustration, gritting his teeth and letting his magic drop. Carefully, the stallion rolled onto his haunches, panting down at his little sister, his mouth parted as he panted hard, a slick dribble of precum drooling to the blanket.

Twilight stared up at her brother for a long moment, swallowing hard to fortify herself. She rolled onto her own haunches, and then stared at him, her eyes narrowing. She stepped forwards, pushing him over onto his back. The stallion gave a faint ‘oof’ at being pushed over, but broached no argument against it, staring up at her.

Grinning, Twilight stepped over him, forehooves straddling his hips as she leaned down, swirling her tongue firmly against the white fur of his stomach where his cock had spit a trail of precum. A low groan left her as the musky taste flooded her senses, and she shuddered, staring up at him.

“I want it in my mouth,” Twilight said in her most seductive tone.

Shining Armor’s eager cock jumped at that, drooling another spurt of precum, and this time, Twilight was there to catch it. Without a hint of hesitation, the young unicorn tilted her head down and captured the tip of his cock, quickly closing her lips over as much of the tip as she could handle, eagerly swirling her tongue against the source of the precum.

Feeling her brother stiffen underneath her, Twilight grinned around what little of his cock she had managed to get in her mouth. His tip had already begun flaring, and it was much thicker at the tip than she had anticipated. Even stretching her jaw open, she couldn’t squeeze it inside her maw. Instead, Twilight settled for closing her lips in a clumsy seal around a good portion of his tip, and swirling her tongue eagerly against that little bit of flesh where his gooey precum was originating from.

One hoof rested on the ground for balance, while Twilight’s other hoof lifted to eagerly stroke her brothers cock, working him off into her maw, eager to taste his semen.

Shining Armor groaned helplessly as his sister went to work on him like that, making his eyes roll back and his entire form quiver in delight. “Oh g-geeze Twilie,” he panted breathlessly, trying his best to focus on her, to fix in his mind the image of his beautiful sister blowing him so eagerly. With a grunt he had to clench his eyes closed, his hips automatically trying to push towards her muzzle.

Twilight hummed with delight as she felt her brother reacting so well to her attentions. Her books told her what stallion’s liked, how to please them orally. She had wanted to bob her muzzle on him, to graze her blunt teeth over his flared tip and tease him to orgasm. But that was impossible with her unable to open her mouth far enough.

Groaning faintly at the musky taste flooding her senses, Twilight shifted her free hoof from his cock, to her cunt, sliding it down her form and beginning to grind it between her legs fervently. she was insanely turned on by what she was doing: much more than she thought she would be.

With her head tilted down, Twilight could only see the expanse of her brother’s chest and stomach, and nothing else. Panting, Twilight drew back a little bit, scooching her haunches closer to her brothers own rump, and angling his cock up as she rocked herself back onto her hindquarters in a sitting position. The new position was a little less comfortable than laying on top of her brother, but with him on his back like that, and his cock standing straight up, when Twilight returned her mouth to his tip, she could stare directly into his eyes. Humming eagerly against the swollen cock in her maw, she kept a seductive, heated eye contact with her brother. Twilight’s smoldering gaze conveyed many things to her sibling; lust, desire, eagerness. She told him with her eyes exactly how much she was enjoying this and exactly how much she wanted him to spill into her suckling maw.

Twilight was gratified to feel the thick member throbbing heatedly against her tongue, and she readied herself to be overwhelmed with her brother’s urgent essence. But then Shining Armor deviated from Twilight’s mental transcript, by leaning forwards, curling up into a sitting position and capturing her horn in his maw, beginning to suckle on it rapidly.

It obviously wasn’t the first horn Shining had sucked, a detached part of Twilight’s mind decided. He had to have practised on Cadance many times to be so good at it. But that part of her mind was a mere whisper compared to the scream of pleasure pulsing throughout the rest of her thoughts. Twilight shuddered and arched as her brother bobbed his mouth on her horn, eagerly suckling and swirling his tongue around it. With a helpless quiver, Twilight began to rapidly, urgently rub at her aching cunt with her hoof, helpless against the sensations rising in her form, pushing her rapidly towards her peak.

Shining Armor pressed his advantage, tonguing at his sister’s horn all the more firmly and applying more and more pressure to it, determined to make her climax at the same time he did. But the thick throbbing in his stiffened cock was reaching its crescendo, and even trying his best to hold back, he was about to blow.

Twilight groaned heavily against the tip of her brother’s cock, gulping down a small mouthful of his precum to help clear her muzzle out before returning to pleasuring him. Each throb of his eager cock in her maw was rewarded with a fervent flurry of licks against the tip, urging her brother to give up his spunk to her suckling muzzle.

The mare was the first to tip over the edge, grunting helplessly and tensing up, her horn glowing in her brother’s mouth as magic oozed from her form. Her thighs tightened around her hoof as she ground it against her clit, and she whimpered helplessly, tears in her eyes as a powerful orgasm pulsed through her form. Her slick cunt clenched again and again in reflexive spasms as her lubricating liquids drooled and dripped to the blanket below.

Shining Armor hummed happily as the metallic taste of magic flooded across his tongue, gratified at his sister’s orgasm. But it was only a few moments later that he himself tensed up, his eager cock flaring and throbbing urgently.

Twilight’s eyes went wide as the first thick spurt spilled into her muzzle so suddenly, splashing across her tongue and coating the inside of her maw in her brother’s hot spunk. The sudden knowledge that she was taking her own brother’s spunk into her very mouth made her tense up in another orgasm as she whimpered, clenching her thighs against her hoof reflexively. She was too far gone to swallow, and Shining Armor was holding nothing back, emptying himself into her maw in rapid, urgent spurts. Twilight’s maw rapidly filled with the gooey, heavy bursts of spunk, pooling in her muzzle. The mare was panting too hard to swallow, and so she did the only thing she could think of without pulling back, opening her mouth up a little bit further and laying a fervent flurry of licks against the pulsing tip. Hot bursts filled her accepting mouth over and over again, the thick white mess quickly filling all available space and then beginning to drool out the corners of her open mouth, dribbling down her jaw and onto the blanket.

Twilight groaned as her brother filled her muzzle with his urgent spunk, feeling each renewed spurt forcing more of the thick mess to spill from the corners of her mouth. Over and over again it filled her muzzle, coating her tongue in the indescribable, intoxicating taste of pure, primal male.

After what seemed an eternity, the spurts died down to a slow trickle, and Twilight slowly drew back, her maw still parted.

Shining Armor slowly disengaged his own mouth from her horn, licking his lips at the odd taste still clinging to his tongue, panting down at his little sister. A low groan left him at the arousing sight of her with her mouth still open like that, holding an obscene amount of his spunk, drooling from her maw to drip to the blanket below.

Twilight’s eyes opened, and she watched him with a sly grin as she closed her mouth and swallowed. It took three swallows for her to clear her muzzle of his gift, and then she opened her mouth again to show him that she had, indeed, managed to swallow all of it.

“You taste good, Shining,” Twilight panted breathlessly. “Musky, and primal...”

Shining Armor stared at his little sister, his ears splaying back and his mouth parted as he panted heavily. “Y-you have no idea how hot that is,” he panted, having trouble finding his voice.

“I have an idea,” Twilight said with a soft, seductive giggle.

Shining Armor gave a lustful growl, and then leapt on his sister, pushing her to the ground and kissing fervently at her stomach. “Time for me to repay the favour,” he growled, as he began to kiss a trail down her form eagerly.

Twilight blinked, squirming slightly on her back to get more comfortable. A giggle left her as she learned of her brother’s intentions, before she gave a gasp of delight and surprise as he suddenly pressed her hindlegs open and delivered a heated lick to her quivering, slick cunt.

Shining Armor grinned up at his little sister, his nose between her legs, inhaling her wonderful scent from point-blank range. With a low, eager hum, he leaned in and delivered another lick to those wonderfully pliable, soft outer lips, watching them deform slightly under the pressure of his tongue. It was so arousing, to see them stretch like that, and he couldn’t wait to just shove between them and fuck her until she was screaming. But first, he had to prepare her.

Rumbling, the stallion pressed in, letting his snout bump up against her sex, his lips parting and tongue sliding forth to give a slow, firm lick from the base of her heated, moist cunt, to the tip, flicking off her clit at the end quite deliberately.

Twilight arched and squeaked faintly at that, hooves flying to her muzzle to stifle the sounds as she quivered softly in delight and automatically splayed her hindlegs further for her brother, offering herself fully to him. “Y-yes Shining...”

Shining Armor flushed faintly at the lustful tone in his sister’s voice, and laved his tongue against her all the more eagerly, deliberately pressing into the crevice of her pink cunt. The strong muscles of his tongue spread his sister’s burning entrance open, just a little bit; enough for his tongue to lave directly against exposed inner flesh that would usually remain untouched. He felt Twilight stiffen in approval, a soft whimper leaving her as her tight pussy, if possible, moistened further.

Grinning, the stallion lifted his hooves to rest on his sister’s heaving stomach, and then slipped his muzzle up higher, delivering a long, firm lick along the outer lips of her cunt in passing, until he reached her clit. He paused them, waiting for Twilight to look down at him.

Twilight peeked her eyes open, panting down at her brother. Their eyes locked, and a slow, sly grin stretched Shining Armor’s muzzle. Without warning, he attacked her clit, closing his lips over it and suckling firmly, and then giving it a violent flurry of licks with his powerful tongue, alternating the two distinct stimulations.

Twilight’s eyes widened and she ground her hoof against her muzzle to keep from screaming to the sky, her back arching so hard that her shoulders almost left the ground. Her entire form spasmed under the relentless oral attack, and very quickly, she came. Twilight screamed in delight and stuffed her hooves in her brother’s mane, eagerly grinding her hips into his muzzle in reflexive delight as she pushed his head towards her in incessant lustful motions. Slick spurts of her liquids washed over her brother’s muzzle, wetting his snout with her lust.

Shining Armor grinned up at his sister, his eyes narrowing lustfully. He licked his lips, and then swirled his tongue once against her drooling cunt in parting, before drawing back and panting at her.

“I want to fuck you so bad right now, Twilie,” Shining panted, one hoof slipping back to stroke slowly at his stiffened member.

Twilight shuddered, her mind muddled from the hot scent and taste of her brother, and the multiple orgasms. But she knew she wanted it. She wanted it deep inside her, claiming her. with a coy smile, Twilight stretching slightly, and then spread her legs in invitation.

Shining Armor fairly pounced on her, diving over top of his sisters form and eagerly, passionately kissing her, the heavy weight of his cock pressed between their forms, grinding against Twilight’s stomach.

Twilight shuddered faintly, peering between them at the tip of his cock, her mouth parting slightly in a low groan, as she deliberately twisted to rub her eager, heated pussy against the base of it. “I-I want it inside me, Shining,” Twilight stuttered, wrapping her hooves around his shoulders. She could smell herself on his muzzle, and it was just making her all the more eager for him to fuck her.

The stallion nodded eagerly, pulling his sister into a fervent kiss, locking their lips together and pressing his tongue slightly past her lips in a passionate embrace. Twilight moaned faintly into the passionate kiss, closing her eyes and shuddering in delight.

Shining Armor wrapped his hooves around her smaller form, shifting back so that his thick tip slid down her form, until it dropped between her legs, grazing over her aching cunt. Twilight sucked in a breath, tensing slightly. Without warning, Shining Armor shifted and then sank himself into his little sister with a low, lustful growl.

Twilight arched under him, her eyes widening and mouth parting as she screaming in surprise and delight, hooves gripping tight around his neck and shoulders. He was so huge inside her! She grit her teeth as he shifted and pressed further into her, stretching her oh-so-tight cunt around his rigid member.

The stallion groaned faintly, gripping around his sister a little bit tighter and heaving his hips against her own, baring his teeth in lustful delight as he sank another inch into the mare, spreading her even further around his throbbing maleness. “Oh g-geeze Twilie... You’re so t-tight...”

Shining Armor paused then, panting, with just the first few inches buried inside his little sister, resting his cheek on her chest and panting heavily, just slowly working his hips back and forth against her.

Twilight whimpered faintly, and then gathered her brother up against her chest, curling down to lap heatedly at the base of his ear, before whispering pure filth into it. “S-Shining... You’re not going to stop now, are you? You’re inside your little sister now... Don’t hold back now. F-fuck me, Shining. Fuck me hard and cum in me, I want to feel it all warm and gooey inside me!”

Shining Armor’s eyes widened at his sisters filthy urging, and his cock throbbed urgently as he shuddered. Twilight panted heavily and then leaned in to kiss him urgently, her tone rising. “Fuck me!”

The stallion shifted his stance, unable to help but accede to his sister’s wishes, spurred on by the dirty wording of her demands. His cheeks flushed faintly with delight at her words, as he grunted as he gripped around her middle and began to do exactly as she asked. Shining’s powerful hips began to grind back and forth, sliding back, and then shoving forwards, sinking into his sister’s tight, spasming cunt. Twilight groaned and arched her back, pushing her hips against his motions, forcing him just that little bit deeper with each thrust. Her hooves wrapped around his chest as she urged him on with incoherent murmurs and whispers of ‘d-deeper...’ or ‘h-harder’.

Soft, stifled groans left the mare’s quivering maw as she was taken by her big brother, feeling his thick shaft spreading her eager, wet cunt, sinking so very, very deep inside her. It was only a few eager thrusts later that the stallion bottomed out in her, spreading her to her very physical limits. Twilight’s eyes widened and she went rigid, her eager cunny starting to spasm and clench at the intrusion of her brother’s cock, milking it urgently for its load.

Shining Armor grunted in helpless delight as he bottomed out in his little sister, feeling his tip graze up against her deepest barrier gently, making the mare stiffen and arch in delight. Panting hard, he buried his nose in against her sternum, hot exhalations washing through her fur. His eyes met her own, and he paused a moment, panting hard, an unasked question bouncing between them.

Groaning helplessly, Twilight nodded enthusiastically at his nonverbal question, grinding her hips towards him urgently. “F-fuck me!” she pleaded urgently, gripping him with her hooves. “P-please Shining!”

The stallion grinned wildly at that, gripping his little sister tight around the middle as he slid back, and then started to fuck her with a primal, fervent pace. His hips shoved up against her over and over again, sinking his eager cock deep inside her repeatedly, stretching her insides with his incessant strokes. Even her clenching, convulsing inner muscles squeezing around his moving cock couldn’t slow his powerful strokes. Hot patters of precum began to spill into Twilight’s rhythmically squeezing cunt, mixing with her slick juices.

Both unicorn’s shuddered, nearing their peaks, their motions getting wild and desperate. Their horns began to glow, sparkling with magic.

Shining Armor grunted helplessly, shoving himself into his little sister over and over again, lifting his nose to rest against her own. He stared into her eyes in a lustful expression of love and desire as he took her hard and fast. A particularly rough thrust bumped his sister slightly.

Their horns touched.

An explosion of magic took place, and the two unicorns stiffened, their eyes clenching closed as blue and purple bolts of electrical magic suddenly linked their horns. They both quivered and tensed, thrown into mirrored violent orgasms by the electric sensations coursing throughout their forms.

Shining Armor went rigid, buried deep inside his little sister, crying out incoherently as his cock tip flared deep inside Twilight, stretching her deepest reaches around it as it throbbed and quivered. Repeated bursts of heavy spunk began to burst from him in urgent jets, splattering across the mare’s inner walls in rapid, wild jets. It took very little time for the thick bursts to overcome the seal of Shining’s flared tip deep inside her body, and the repeated spurts began to drool from around his embedded cock, seeping out of his little sister and making a mess of her tail.

Twilight screamed to the heavens, before burying her muzzle in against her brother’s neck, gripping around him tighter as she rocked her hips reflexively, her insides milking around him. The sensation of his flaring tip spreading her deepest reaches sent her absolutely wild. She came again and again, her tight muscles rhythmically clenching and squeezing around her brother’s cock, milking him for the thick load he so eagerly supplied her with, until each climatic clench squeezed out trickles of his heavy, thick, sticky essence to drool and dribble from her used cunt.

After several long moments, the two unicorns went limp, panting hard and splaying out with eachother. Shining Armor groaned, lifting a hoof to try and move his limp mane out of his eyes, giving up after the third failed attempt and just resting atop his little sister, still buried in her used cunt.

Twilight likewise groaned, loosening her grip on her brother’s shoulders, untangling her hooves from his mane and then just splaying out, eyes closed, enjoying the warmth of Shining’s heavy spunk pooled in her to the point of overflowing.

The alicorn of love watched from the treeline with a faint giggle, removing her hoof from between her hindlegs, inspecting the moisture collected there. The aphrodisiac in the bread had worked like a charm, and a little ‘help’ from her magic had sealed the deal. And what was even better, was that she had got to watch the taboo union.

Cadance settled herself down to wait until her legs stopped shaking, so she could leave, watching brother and sister resting in euphoric bliss. It really was beautiful to her. Love was love, after all. And being taboo just made it all the more delicious.

Reprobate Depravity

Twilight Sparkle knocked on the door to the room shared by her brother Shining Armor, and his wife Princess Cadance. She cleared her throat, calling out: “Shining Armor?”

The young unicorn was being cautious, her tone a little nervous and wavering. She hadn’t seen her brother since their little tryst by the lake. And by ‘tryst’, she meant the wild incestuous rutting they’d shared, after burying their mouths in and around eachother’s respective genitalias, Twilight reminded herself. The image of her brother, panting and satisfied, fast asleep by the lake with her liquids in his muzzle and the softening length of his stallionhood, mixed with his own pearly semen, was burned into her mind. Twilight would never admit it, but she wished she was a painter, so she could immortalize the scene on paper. And then clop furiously to it whenever the urge took her.

It had been over two weeks since that point, and Twilight was resolved to talk privately with her brother on the subject. She was going to cut it off before it could happen again, stop the depraved thoughts happening in both of their minds. She had a counselor all lined up, sworn to keep her ‘little secret’ confidential when she dragged her brother to the appointment. She would excise the incestuous fantasies from both of their minds so they could resume a natural brother/sister relationship.

And Cadance. The one who had started all of this. Twilight still wasn’t sure how she would deal with her. Maybe she could even convince the princess to attempt to make Shining Armor see how depraved he was?

There was a shuffle of movement from behind the door, the sound of the handle turning, and then it was thrown wide.

“Twily!” Shining said in an excited tone, grinning from ear to ear and hugging around her neck with his forehooves as though he had been expecting to see her. “How good of you to come! Come in, come in!”

Completely confused and wrong-footed, Twilight tentatively stepped into the room, closing the door behind herself.

Shining Armor bounded over to the bed eagerly, throwing himself upon it with the sound of straining bedsprings, the stallion curling around to peer at his sister with a grin, before asking coyly, “Are you coming?”

Blinking once, her ears pinning back, Twilight Sparkle stepped slowly over to the bed, uncertainly pulling herself up onto it, sitting down awkwardly on her haunches.

“Shining, I-”

Shining Armor cut her off by crawling closer to her and leaning up to kiss her heatedly, pressing their lips together and tilted his head slightly to the side to press his tongue between her lips.

Twilight made a soft sound of alarm and dismay, trying to push the forceful stallion away, wrenching her lips from his own, her cheeks flushing heatedly. “Shining, Stop!” Twilight said forcefully, her tone commanding. “I’m your sister! You’re not supposed to be kissing me!”

The stallion paused at that, a look of concern coming across his muzzle, before his expression turned into that wry, playful grin again. “Ohhh, I know what you mean, Twily!”

In an instant, Shining Armor was upon her again, tugging her around and throwing her onto her back on the bed, a hoof pressing against her stomach as his other powerful foreleg press her hindlegs open.

Twilight had time to gasp in surprise, her eyes widening, twisting to stare down at her brother, her cheeks burning.

Shining Armor drank in the sight of his sister’s pussy, his eyes narrowed and tail flicking eagerly back and forth. With her legs spread, everything was visible, from the puffy outer lips, visibly soft and covered in that short purple fuzz, and the sliver of pink between them, promising slick, smooth inner flesh. He licked his lips once, glancing up to her face with a grin and then shoving his nose in against her. Immediately, that strong, velvety tongue began to lap at her, working at first in a slow, strong motion, from the base of her purple cunt, right up to the tip, flicking off her clit.

The unicorn whimpered, her hooves flying to her mouth as her stomach convulsed and her sex clenched immediately at a non-existent object. Twilight hadn’t managed to bring herself to an orgasm for a full week, determined not to clop to her very own brother, and it had left the young unicorn antsy, very easy to work up. Already, those soft purple lips were swelling with blood, moisture beginning to make itself apparent between the soft outer lips.

Shining Armor lapped at her harder, grinning up at her as he tongued at her tight cunt firmly, eyes locking on her own over the curve of her stomach.

Already looking disheveled, with her hips twitching, Twilight curled around to try and grip at her brother’s horn, to push his face away from her rapidly heating folds.

The stallion took her motions for assent, and quickly swirled his tongue up to toy with her clit, closing his lips over it and beginning to suckle powerfully around it, humming to add vibration.

Twilight yelped, her back arching hard and her entire form spasming, her stomach muscles rippling as a small, unexpected orgasm struck her, her plump cunny giving up a sudden slick gush of her liquids.

Neither of them heard the door open and then close again quietly.

Shining Armor grinned, giving a delighted sound as he slipped down to tongue at the base of her quivering sex, swirling his tongue through her sweet liquids with an eager hum, muzzle pushing against her powerfully.

A weight settled on the bed, and Twilight looked up in time to see herself staring down at her, before she pressed her muzzle down and captured her horn in her mouth, pressing right down to the base, suckling and swirling her tongue along the entire stiff spire in a practised motion.

Twilight whimpered helplessly, her entire form tensing up as she felt her horn and heated pussy both being assaulted by muzzles. Her hoof finally found her brother’s horn, and she gave a soft shudder and a whine, clenching her thighs around his head and wrapping her hoof further down to twine with Shining’s mane. With a heated groan, the young unicorn gave in, tugging her brother’s muzzle against her heated cunt while grinding her hips towards him helplessly.

Shining Armor gave a low rumble of delight against her, tongue working against her hard and fast, trying his best to dig his tongue into the moist slit, letting his velvet tongue wash against the soft, silky-smooth inner flesh.

A helpless groan left the unicorn as she arched and quivered, her head being held in place by firm, but gentle hooves at her neck, just at the line of her jaw, so that her clone above her could work her muzzle all the more firmly over the stiff horn, bobbing her head firmly back and forth while humming heatedly.

The horn within the clone Twilight’s muzzle began to glow fitfully, pulsing with magic in the same cadence as the tonguing she was receiving at both her aching cunt and sensitive horn. Her hindlegs gripped her brother’s head as her hips shoved against his face reflexively, the young unicorn screaming in delight as she came hard. A burst of magic filled her clones muzzle, shining so bright that it was visible through both her cheeks and the paint covering them, while a hot gush of liquids splashed across her brother’s face, slicking his cheeks and muzzle with her liquid lust.

Slowly, Twilight came down from heaven, giving soft little breathless whimpers as she collapsed back into the arms of painted-Cadance. Cadance lifted her muzzle from the unicorn’s horn, grinning down at the slick countenance of her husband, with his own sister’s liquids dripping from his pristine white fur.

Grinning, Shining Armor swirled his tongue against his sister’s cunt slowly, and then looked up at her face.

The stallion paused, blinking once.

Two Twilight’s greeted his gaze, one flushed hard and panting, looking elated, her horn slick with saliva, while the other Twilight was perfectly composed, licking her lips innocently and smiling down at him, raising a brow.

“T-Twily?” Shining asked, his voice suddenly hoarse as he licked his own lips nervously.

Cadance gave a soft laugh, nudging the unicorn gently for a moment. “She’s taken a vacation, lover. Can I take a message?”

Shining Armor stammered, his cheeks flushing hard as he quickly tugged himself away from his sister, looking away, the blush intensely visible on his white furred cheeks. “I-I thought it was you, Cadance!”

Cadance giggled and shook her head. “Shining... I was there at the lagoon. I was watching,” she purred seductively, gently laying the euphoric purple unicorn aside and then moving towards her brother, rubbing herself up against his side, her tail flicking to trail along the stiff length of his flesh bobbing beneath his belly.

“Y-you were watching?” Shining Armor asked, his tone a squeak.

The princess nodded slowly, giving a sly grin. “Watching and clopping furiously.”

Shining Armor gave a whimper, shifting his weight from hoof to hoof slowly.

Twilight sat up with a low groan, panting and visibly shaken, peering over at the pair, looking from herself to her brother. Her usually studious mind slowly put two and two together. “C-Cadance...”

Cadance nodded gently, smiling. “I see my lessons with Shining have paid off. He made you orgasm quite hard, didn’t he?”

Twilight nodded automatically, her cheeks flushing as she tried not to look at the length of stiff pony cock hanging beneath her own brother’s stomach.

“You want this, don’t you,Twilight?” Cadance asked, slipping a purple-painted hoof down to push at the thick member, making it bob and twitch.

Flushing, Twilight nodded, refusing to vocalize her answer.

Grinning, the alicorn tugged at her husbands mane, pulling the willing but nervous stallion over to the bed, before she heaved her hips against him, pushing him onto the bed and rolling him onto his back calmly. A hoof lifted to gently trail down the length of throbbing member, and Cadance lifted her gaze to Twilight’s.

Twilight was staring at her brother’s rigid member with embarrassment and guarded desire, a hoof stuffed between her legs as though to hide herself, even though she was slowly grinding herself against it. Twilight glanced at Cadance, realising that she had been caught staring, and her blush redoubled, burning on her cheeks as she bit her bottom lip and looked away.

“Shining made you orgasm... it is only fitting that you return the favour, yes?” Cadance asked, grinning, casting her gaze from one sibling, to the other.

Shining Armor stared at his sister, panting, his cheeks, neck, and the base of his ears flushing with warmth. He didn’t say anything, but his throbbing cock spoke for him, pulsing intently at the idea of his own sister tending to him.

Still biting her bottom lip, Twilight nodded, and then turned her nervous gaze back towards Cadance and the thick cock she was stroking. “Y-you were watching when w-we...?”

Cadance nodded slowly, giving a sly grin.

“W-why didn’t you sat anything?” Twilight asked, inching closer and reaching out a tentative hoof to rest on the throbbing member, feeling the warmth pulsing through it.

“I hadn’t seen you since then,” Cadance said with a sly grin, casting her gaze back towards her husband. “I’m willing to bet he’d just love to have a pair of Twilight’s tending to him,” Cadance murmured with a heated grin, squeezing the base of his member while Twilight herself began to stroke her hoof slowly up the length of the stiffened staff. “Wouldn’t you like that, Shining? Having two of your little sisters tending to your stiff stallionhood?”

A low groan answered her, and a spurt of precum drooled from the tip of the thick member, spilling across the stallion’s stomach.

Flushing hard, Twilight leaned over her brother further, until her chin was near the tip of the long member, the uncorn stammering faintly, “S-shining? D-do you want me t-to...”

Shining’s head lifted, and he bit his bottom lip hard, looking from one Twilight, to the other, giving a low whimper and then nodding earnestly. “Y-yes! P-please!”

Twilight shuddered, pressing down until her chin bumped the thick tip, allowing her to inhale the potent, musky scent of her brother. Without her mind clouded with insatiable lust, she had time to realise what she was doing, to really cogitate on the fact that she was about to suck on her brother’s cock.

Flushing hard, one of Twilight’s hoof’s pressed down between her thighs, grinding against her drooling cunt as she pressed down and swirled her tongue through the trail of precum on her brother’s chest, following it up to the fleshy tip of his cock and swirling her tongue heatedly against it.

Shining Armor gave a low growl of delight, his back arching as he shuddered and stared down at the sight of his sister beginning to tongue and lap at his drooling tip, while his wife, a perfect clone of his sister, watched!

Twilight mouthed over his tip, panting hard through her nose at the taste of her brother’s musk flooding her muzzle, and Shining Armor groaned as she began to delicately push his tip into her muzzle, stretching her mouth around the thickness of it. Shining Armor gave a soft grunt of delight as he watched his sister taking his tip into her muzzle. Beyond that, he saw his wife - his sister - pressing her muzzle down to swirl her tongue heatedly against his balls, the ticklish sensation making him jump and jerk in surprise and delight.

The purple unicorn gently pushed her muzzle further down his member, grinding her hoof more firmly between her hindlegs, working against her aching cunt repeatedly. Her lips stretched around him until her mouth was completely full. A spurt of precum hit the back of her throat, and she gave a muffled groan around him, shuddering and beginning to rub her aching, heated cunny rapidly, even as she started to bob her muzzle on her brother’s throbbing cock.

Cadance grinned up at her husband past his sister’s flank, her gaze pausing for a moment on the sight of Twilight masturbating as she went down him, before she flicked back to the expression of unabashed pleasure on Shining Armor’s face.

Purring, Cadance began to suckle at his testicles, her hooves sliding forwards to grip around the base of his member, beginning to eagerly stroke him off while Twilight suckled at his tip, even as she stared up at him with her most seductive glare.

Shining Armor whimpered, watching the two different images with helpless delight. One on hoof, he had Twilight between his thighs, suckling and lapping at his nuts, glaring up at him seductively, giving him exactly what he wanted. And then, just to the side of this his actual sister was tonguing at him, whining in the back of her throat and masturbating as she blushed at the sheer naughtiness of what she doing!

Already, Shining Armor could feel a tightness growing in his chest, that little tingling in his loins becoming an alarming buzzing, his hindlegs growing weak.

Cadance grinned and pulled off his testicle with a soft pop! of suction, quickly crawling up to where Twilight was eagerly bobbing her muzzle. A gentle hoof stopped the unicorn, and Twilight’s eyes flicked open, the unicorn blinking at the image of herself, reluctantly releasing the thick member from her muzzle.

Grinning, the alicorn shifted and swirled her tongue around Shining’s drooling tip. “Allow me...” she whispered heatedly, quickling diving her muzzle down over the throbbing member, bobbing in earnest.

Shining Armor grunted and arched, shuddering and giving a low cry of delight, staring down at the image of his sister watching herself bobbing on his eager cock, the entire thick thing throbbing and pulsing against her tongue.

Cadance pulled back suddenly, and pushed the stiffened cock towards Twilight. Twilight flushed, but quickly slipped it back into her muzzle, bobbing on it as Cadance had done, though she was noticeably different. Where Cadance swirled and lapped with her tongue, Twilight merely swirled her’s against the underside of the hot member, suckling gently at her mouthful.

The alicorn gave an impatient sound, and Twilight relinquished the spire of flesh to her babysitter.

Grinning, Cadance pushed her mouth back over the member, laying her tongue against it, feeling the throbbing and jerking of it within her mouth, so close to finishing. With an inward giggle, the princess began to bob her muzzle, hooves lifting to start jerking off the stallion with rapid strokes, encouraging his orgasm.

Twilight panted faintly, watching with interest as her facsimile worked her own brother’s cock with such an earnest bobbing and jerking pace.

Cadance tugged back as the thick cock throbbed, and Shining Armor groaned, tensing up all over. She pushed the thick member back towards Twilight, just in time for the first thick spurt to splash across her muzzle, leaving a long line of white from her nose to her forehead.

Twilight stared with wide eyes as the throbbing cock gave up another slick burst, spilling into her mouth, already opened in anticipation of accepting the thick member. Her gaze flicked to her babysitter, and she shuddered, before she dove her mouth over the throbbing cock, suckling and bobbing her muzzle in earnest.

Shining Armor grunted and arched as he felt his sister bobbing and suckling on his cock mid-orgasm, his hooves clenching at the bed helplessly as he cried out aloud, thick, hot bursts of his gooey heavy cum sspilling into the suckling mouth again and again.

Twilight shuddered, her ears pinning back and her free hoof shoving against her clit roughly as she felt her brother spilling his urgent load into her mouth, coating her tongue and filling her muzzle with the musky taste of his spunk.

After several long, intense moments, the throbbing in the length died down, and Twilight whimpered muffledly around her mouthful, beginning to slowly draw back.

Cadance was there waiting, quickly pulling the unicorn into a heated kiss before she could swallow her brother’s thick load. The princess twisted her muzzle and parted her lips, forcing Twilight to likewise open her mouth, the princess meshing her tongue with Twilight’s, sharing the musky, gooey spunk between their mouths.

Shining Armor came back down to earth to the image of two of his sisters sharing his essence, the one with the messiest mouth whimpering and groaning helplessly, her cheeks flushing hard.

The two Twilight’s pulled back, and swallowed, one of them flushing hard while the other gave a naughty grin, raising a brow. “Never kissed a girl, Twilight?”

Twilight flushed hard, shaking her head.

Shining Armor panted heavily, looking between the two with a low groan, slowly relaxing.

Cadance grinned innocently, and then rolled onto her back, slipping a hoof down to spread her slick sex. “Well... there’s a first time for everything. You use your tongue on me... and I’ll return the favour.”

Twilight stared, her eyes wide, gazing at herself spreading her legs and offering such a naughty, lesbian act! But there was still an ache between her legs, and it was a tempting offer...

Flushing deeply, exchanging a glance with her brother, Twilight crawled over to her clone and then carefully crawled atop her, nudging her nose against her clone’s nose for a moment, her blush intensifying. Panting softly, Twilight slowly slew around, stepping carefully until her hindlegs were on either side of Cadance’s chest.

Cadance grinned, wasting no time at all, splaying her hindlegs as she wrapped her hooves around Twilight’s middle and pulled her hips down against her muzzle, shoving her tongue into the unicorn’s leaking cunt without a hint of hesitation.

Twilight groaned faintly, her legs going weak and her eyes sliding closed. A soft, feminine scent assaulted her nose, and she blinked once, casting her gaze downwards to the spread thighs of her babysitter right in front of her. The soft outer lips of her cunt were plainly visible, slicked with moisture and eager for attention. Twilight flushed even harder, leaning in tentatively, and then giving the slick entrance an experimental lick.

Shining Armor rolled onto his side, a hoof pressing against his stomach and slowly beginning to work at his hardening cock as he watched his sister in a soixante-neuf with herself! He could plainly see Twilight’s tongue swirling at his wife’s quivering pussy, delicately, tentatively lapping across the heated folds. Past that, Cadance’s muzzle was buried between Twilight’s thighs, tonguing powerfully at the drooling pink and purple slit, a dribble of liquids drooling slowly down her chin.

Whimpering, Twilight pressed in even further against the princess’ drooling cunt, swirling her tongue more firmly against it, becoming more comfortable with the motions and the idea of going down on another mare.

Cadance drew back for a moment, and mouthed something to her husband. Twilight paused, blinking, before her eyes widened, feeling Shining Armor suddenly climbing atop her. Her cheeks warmed again, and she gave a soft shudder, lifting her hips up invitingly, even as her knees went weak with the knowledge that her brother was going to fuck her, even as she was exchanging oral with Cadance!

Shining Armor took the offer of lifted hips, grinding himself against her with a heated groan, and then shifting to begin stretching her around his tip with an eager hiss. Twilight whimpered, gripping Cadance’s hips tightly, pushing herself back against her brother with a firm pressure to help that thick cock spread her aching cunny. A soft tongue trailed against her clit, even as her brother sheathed himself inside her, and Twilight fairly screamed, shuddering and going weak as a fitful burst of orgasm liquids spilled from her stretched cunny to drool from around the embedded cock.

Cadance grinned, lapping at the drooling liquids as Shining Armor gripped his sister and began to hump into her slowly, sliding back and then grinding forwards, allowing the unicorn to become accustomed to the thick cock filling her.

“M-mate me b-brother,” Twilight whimpered breathlessly, her cheeks burning as she buried her muzzle back between Cadance’s thighs and began to tongue at her powerfully, lapping fervently at the alicorn’s own drooling cunt.

With a low growl, Shining Armor did as his sister asked, gripping around her middle with his hooves and beginning to rock his hips powerfully, the circular motions sliding the girth of his cock out of her gripping cunt, before sinking deep inside her again, spreading her velvety soft depths around him. Cadance watched all this with an eager gaze, with the perfect ring-side-seat to the main event, her nose a mere inch from the action, soft tongue occasionally lapping some of the buildup of Twilight’s moistness where it was gathering at her tip of her clit.

Twilight cried out aloud into her clone’s moist cunt as she was taken by her brother, her ears pinned back and hips pushing in counterpoint to his motions, her tonguework getting more and more erratic as she was taken.

Panting in delight, Shining Armor began to take his sister harder, shoving himself hilt-deep inside her tight, gripping cunt, until his tip kissed against her cervix. The shock of the bottoming out made Twilight whimper and shudder, orgasming instantly at the mix of pain and pleasure, a slick burst of her liquids drooling from around the thrusting cock to splash across Cadance’s muzzle. The princess for her part gave a cry of delight, lapping eagerly up across the messy joining of the two siblings, whispering encouragement.

“Fuck her, Shining! Cum in her!” Cadance urged, grinning wildly and grinding her quivering cunt against Twilight’s muzzle. “Fill her with your spunk!”

Shining Armor whimpered, his own ears pinning back as he nudged his sister’s cheek gently. “T-Twily... C-can I?”

Twilight pulled back from Cadance’s sex just long enough to nod fervently, before burying her tongue back in the alicorn’s cunt, tongue working at her furiously.

Growling in delight, Shining Armor began to fuck his sister with an urgent, eager pace, shoving his hips against her over and over, rocking both of their forms back and forth as Cadance stared at their union with lustfully narrowed eyes.

Twilight’s eyes widened and she stiffened as she Cadance suddenly latched onto her clit, suckling powerfully and tonguing at her, even as Shining fucked her hard, making the unicorn tense up and orgasm again, her insides clenching around her brother’s thrusting rod, squeezing and milking it.

Shining Armor grunted, braying heatedly as he shoved roughly into his sister, gripping her tight and burying himself into her until his tip was mashed against her very deepest barrier, the flaring tip caught and squeezing by her powerful inner muscles, making it almost unbearably tight inside her. The tightness snapped, and the stallion snarled, crying out in triumph as the entire length of his cock throbbed and jerked, trapped by Twilight’s squeezing, orgasming cunt, the sudden hot bursts of spunk splattering across her deepest barrier being squeezing out instantly by the grip her depths had on him. The stallion grunted, shoving his hips back and forth a few inches as he emptied himself into his willing sister, the two of them crying out in delight at the sensation of his hot load coating her insides and filling her completely.

Cadance stared with wide eyes, her chest heaving with excitement as she watched Shining Armor spilling into his sister right in front of her, a slow buildup of white mess heralding what was to come. The princess of love opened her muzzle up with an eager sound, closing her eyes and holding steady. A moment later, the first thick dribble of Shining Armor’s spunk spilled from Twilight’s squeezing, spasming cunt, drooling from around his embedded cock in a thin line, right into her muzzle.

The princess continued to hold her mouth open, grinning widely as the warm mixture of Twilight’s and Shining’s orgasmic liquids drooled into it, rapidly filling her muzzle until it began to leak from the corners of her mouth. A low groan left the alicorn, and she shuddered, a hoof grinding between her legs to bring herself to a quick, messy orgasm at the taste of the two and the sight of their finished joining directly above her.

The alicorn whimpered around her mouthful, closing her eyes and shuddering, her legs going weak as her liquids spilled out between her thighs, wetting the bed with her slick moisture as she held herself in position. The three of them looked like an adults-only fountain, with the slick whiteness drooling slowly between Cadance’s eagerly spread lips, until she closed her mouth and swallowed audibly, giving a low groan.

“You two are so naughty!” Cadance said with a giggle, leaning up to lap at their joining, swirling her tongue across cock and cunt alike, cleaning the slick white mess that was still sluggishly being squeezed free the unicorn’s slowly relaxing depths.

Twilight stood at the door, peering back over her shoulder with a smile. Shining Armor and Cadance were on the bed, all clean now after a long bath together where the three of them had lazed and had a nice talk about mundane things.

The couple smiled and waved at her. “Goodbye, Twily!” Shining Armor called.

“Come back soon, Twilight!” Cadance called in counterpoint, smiling innocently.

Twilight couldn’t help but giggle to herself, her cheeks flushing faintly as she closed the door behind her and began to make her way out of the castle.

She had a counselor booking to cancel.

Consecrated Depravity

Twilight Sparkle tentatively knocked on the door to the private quarters of Princess Cadance and her brother, Shining Armor. Twilight’s new wings twitched nervously, and she grit her teeth, grimacing at the odd sensation of her new feathers brushing against eachother.

The door clicked and swung open, revealing Shining Armor standing there, blinking down at his sister. “Hey Twily!” Shining Armor said with his predictable enthusiasm, lifting a hoof to ruffle her mane. “I never noticed that you got taller! How is my favorite princess?”

Twilight smiled nervously, shifting anxiously in place, her ears splaying back. “H-hi Shining. Is Cadance there?”

Shining Armor shook his head sadly. “‘Fraid not, Twily, she’s in court at the moment. Talking to the Equestria Games manager.”

Twilight winced, hanging her head.

“Can I help you with anything?” Shining Armor asked, his expression turning to one of concern.

Twilight made a soft, annoyed sound in the back of her throat, her wings mantling slightly. “I... I need to talk to somepony. About my wings. There’s nothing in any of my books about the issue, and Fluttershy and Rainbow Dash both said they haven’t experienced it!”

Shining Armor frowned at that, his brow furrowing. “Come in, Twily. You can talk to me.” He stepped aside, waving a hoof towards the room.

Twilight stepped inside uncertainly, her wings twitching again, making her entire form shudder.

Shining Armor closed the door, before stepping over to the bed, pulling himself up onto it, curling up to allow his sister onto the bed as well.

Cautiously, Twilight pulled herself onto the bed as well, biting her bottom lip as she carefully spread her wings out to lay them flat against the bed.

“So, what’s the matter with your wings?” Shining Armor asked, leaning in to peer at them, gently reaching a hoof forwards to stroke across the leading edge of one of them.

Twilight yelped at the contact, snatching her wings back and shuddering, squiming in place. “Don’t touch them!”

“What’s wrong?” Shining Armor queried, raising a brow confused.

“They’re sensitive,” Twilight admitted, flushing deeply. “They were fine for a little while after I got them... but now, every time I touch them...” Twilight trailed off, biting her bottom lip and pinning her ears back. “I can’t fly with them, because the wind through my feathers... ermh... excites them.”

Shining Armor stared at his sister with narrowed eyes, blue tail giving a slow flick back and forth. “Excites them?” he asked curiously, his tone turning delicate. “Do they... hurt?”

Twilight shook her head slowly her eyes wide and placating. “T-they turn me on,” she admitted in a breathy whisper. “I had to kick Spike out of the library while I was searching through the books because I kept brushing my feathers up against the bookcase and... well...” Twilight lowered her voice, “I had one hoof on my books and the other stuffed between my legs.”

“Puberty?” Shining Armor suggested with a goofy grin.

Twilight gave a sound of frustration, flailing a hoof at her brother. Shining Armor grinned, leaning out of the way deftly.

Twilight’s expression turned hopeful, “Did... did Cadance ever go through anything like this?”

Shining Armor gave a thoughtful sound at that, before shaking his head. “No, not that I know of. She does enjoy having her wings rubbed though...” the unicorn paused then, grinning and leaning closer to whisper into his sister’s ear, “Especially when I’m screwing her from behind.” To reinforce his words, Shining Armor gently dragged a hoof down the leading edge of Twilight’s left wing.

Twilight yelped again, clenching her teeth as her entire form tensed, warmth blossoming on her cheeks and neck. “Even though I’m a princess now, you still want to screw me?”

Shining Armor smiled helplessly at that, ruffling her mane with a hoof. “C’mon Twilight. You want me as much as I want you. And I have a idea for helping with your wings.”

Twilight flushed a little bit further at the accusation, and she bit her bottom lip, looking away. “W-well... I did come in here... alone...”

Shining Armor grinned at that, gently trailing his hoof through her mane. “Ever heard of exposure therapy?”

Blinking once, Twilight shook her head.

Shining smiled and shifted closer to her. “Well, you got these new wings. And you’ve never really done anything with them... It’d be natural for them to be sensitive.”

“Understanding why doesn’t help treat them,” Twilight said with a soft huff.

Shining Armor grinned at that, leaning in to kiss her cheek and chin affectionately, a hoof lifting to delicately trail down the upper edge of her wing, making his sister shudder. “Basically, we’ll stimulate your wings repeatedly. Over and over again. Until they’re desensitized.”

Twilight flushed faintly, her ears splaying back. “B-but that’ll mean...”

Shining Armor gently placed a hoof on her lips, quieting her, “Twily. Let your big bro take care of this problem for you.”

Flushing further, Twilight stared up at her brother, and then nodded slowly.

Shining Armor grinned, growing visibly excited at her acquiescence, his eyes narrowing as he licked his lips. His hooves came up, and he shifted around to lay against her side, beginning to stroke his forehooves firmly along her wings.

Twilight stiffened, arching helplessly into the bed, her tail giving a slow flick as her wings sprang out and quivered stiffly in place. One of her hooves automatically slid down her stomach, worming between herself and the bed until it was pressed firmly between her hindlegs, the other hoof pressing to her muzzle to stifle her noises. She began to grind her hoof against herself, wimpering softly. “Y-you had better be prepared to fuck me into the floor,” Twilight whispered back to her brother.

Shining Armor stared, watching as Twilight’s tail twitched, moving far enough to the side to reveal her hoof and her moistened treasure. The soft, purple fur of her coat puffed out slightly with the pliable outer lips of her sex, framing the perfect shade of pink hidden within. Each time Twilight’s hoof ground up against herself, her outer lips shifted, revealing a little of her inner flesh to her brother.

Shining Armor swallowed hard, staring, entranced, before he lifted his gaze suddenly and blinked, nodding earnestly. “O-oh yes, I will,” he said belatedly, realising that he had stopped stroking her wings. Immediately, he resumed his motions.

Twilight peered at him over her shoulder, smiling devilishly, watching the way his gaze lingered under her tail. “I really turn you on, don’t I?” Twilight asked coquettishly, batting her eyelashes, her wings flexing eagerly.

Shining Armor nodded dumbly, staring under his sister’s tail, his eyes wide and tail flicking eagerly. The tip of his swelling cock was beginning to make itself known, poking out from under his stomach.

Twilight whimpered faintly, grinding her hoof against herself all the more eagerly, her ears pinning back and eyes clenching closed. She bit her bottom lip, rocking her hips into the motions of her hoof impotently, shuddering. Her eyes snapped open, and focused on her brother’s throbbing member, and she licked her lips eagerly, her eyes narrowing and pupils dilating with lust.

“Shining, I need you to stop rubbing my wings,” Twilight murmured, her tone soft, but commanding.

Automatically, Shining Armor stopped and drew back slightly, a hoof trailing down to his visibly throbbing member, stroking it slowly. “What do you need, Twily?”

Twilight’s eyes narrowed, and she giggled, rolling onto her hooves, and then stepping off the bed, crouching down, lifting her rump into the air. It would have been an inviting pose, had she been facing away from him. Twilight stared up at her brother hungrily, licking her lips. “I want you to rub my wings, brother. I want you to grind against my wings while you fuck my mouth.”

Shining Armor stared down at his little sister as she opened her mouth teasingly, poking out her tongue, her wings mantling slightly, shifting and rustling. his breathing intensified, and he shuddered, before rolling over onto his hooves and pouncing on her. His forehooves automatically found her wings, beginning to rub along them, touching at the joints, kneading and stroking. His throbbing, eager cock bobbed in front of Twilight’s nose, eager for attention.

Twilight gave a low moan at the touches to her wings her hindlegs trembling. Her eyes fixed on the bobbing cock of her older brother, and with a lusty, eager growl, she leaned forwards and dragged a firm lick against the tip, before drawing back, watching with a warm smile at the way the thick member bobbed.

Shining Armor gasped at the lick, his ears pinning back and hips rolling slightly. A thick spurt of precum drooled from the tip of the thick head, and immediately, Twilight was there, suckling and lapping directly at the slit where the musky fluid had emanated. Shining Armor groaned, tensing up and trying his best not to thrust, burying his nose against one of her wings. After several seconds, he humped his hips on reflex, and then bit at her wingjoint lustfully.

A soft whimper left the alicorn, and she shuddered, arching harder at the sensation of her brother teasing her new wings like that. Her tongue swirled and lapped at the very end of his cock, digging into the cumslit, eager for more of that musky precum, the hot scent of her brother’s arousal intoxicating in its intensity. The thrust against her muzzle caught her by surprise, and she got a facefull of her brother’s cock, the length of it grinding across the bridge of her nose. The bite to her wing made her stiffen and whimper, tensing up, her arousal starting to drip from the slick, clenching alicorn cunt.

Twilight drew back, panting and nudging the tip of her brother’s member, her eyes wide and wild. “I want you to fuck my muzzle, brother,” Twilight whispered hoarsley, a hoof lifting to cup the base of his member, holding it steady as she stroked her tongue around the head. “I want you to cum in my mouth. I want to taste your spunk, Shining.”

Shining Armor’s eyes widened at Twilight’s tone and her words. It was the kind of language he had come to expect from Cadance, but certainly not from his sweet, innocent sister! It was... hot.

Twilight growled heatedly as she finished speaking, slipping her hoof down to cup his balls, before she shoved her muzzle over his member without warning, beginning to bob and suckle in earnest.

Shining Armor whimpered and shuddered, biting down on her wingjoint a little harder, his hips giving another reflexive thrust at the sudden suckling and warmth around his eager cock. Twilight took the thrust eagerly, bobbing down against it, grinding her tongue along the underside of his member firmly. Panting helplessly, he lifted his muzzle from her wing and squeezed at the base of them firmly with his forehooves, listening to the way his sister whimpered and shuddered. The hot scent of her arousal met his nose, and he shuddered, shifting a hoof down to her cheek.

A heated growl left the alicorn as she felt his hoof on her cheek, automatically knowing what it meant. She tugged back off his aching length with a pop! of suction, a line of precum drooling down her chin. “Y-yes, brother! Fuck my muzzle! Fill my mouth with your gooe-Mrf!”

Twilight’s heated cajoling was cut off as Shining Armor found her mouth with his cocktip, wasting no time in shoving himself back into her eager muzzle. Without hesitation, she started to suckle around him again, bobbing and tilting her head to increase the suction and friction, tongue grinding and working against his tip.

Shining Armor was just as eager to fill his sister’s muzzle with his spunk, as she was vocal about getting it. The new, more aggressive style was turning him on so much that he was sure he’d make a mess of her mouth very soon. Wasting no time at all, Shining Armor began to thrust eagerly into his sister’s mouth, sliding back and then humping forwards until his tip bumped the back of her throat.

Twilight groaned muffledly around her mouthful, her wings mantling and quivering against her sides as she lifted both forehooves to grip around her brother’s rump. One hoof found his heavy nuts, squeezing them delicately, urging him to fuck her muzzle harder, while her other hoof wrapped around his rump and pulled.

Shining Armor couldn’t help but thrust harder into his sister’s mouth as she pulled at him. With a push of her head and a straightening of her body, Twilight pulled him even harder, and Shining Armor gave a cry of surprise and ultimate delight as he felt the tight grip of his sister’s throat opening to allow the tip of his cock inside. Twilight gagged for a few moments, before smiling hard and beginning to swallow.

Shining Armor’s eyes widened, and he stood on the tips of his hooves, thrusting back and forth an inch of so as he felt his sister suckling and swallowing around his cock, his ears pinning back as he bit his lip so hard he could taste blood. “T-Twily!... f-fuck!” Shining Armor panted past his quivering lips, feeling his entire form tensing up.

Twilight gave a low groan around her mouthful, squeezing his rump, balls, and swallowing hard around his cock, a muffled sound of encouragement reaching her brother’s ears.

Shining Armor whimpered as he stared down at his sister, before finally giving in. With a heated snarl, the stallion gripped his sisters chest in his forehooves, and then drew back, stiff cock throbbing on Twilight’s tongue, before he shoved forwards, sinking deep, deep inside her throat. Twilight smiled hard around him again, purring in delight at his sudden initiative.

With a whimper of delight, Shining Armor began to thrust into his sister’s mouth in earnest, sliding back and shoving forwards, rutting her muzzle like he would fuck her cunt. His hips met her muzzle, and he held himself there, cock stiff and throbbing, buried in her throat entirely. “T-Twily. I-I’m gonna c-cum!”

Twilight gave a muffled sound of anger around his cock, glaring up at him with an expression that said more eloquently than words ever could, exactly how much she wanted him to spill into her mouth.

Shining Armor leaned over his little sister again, starting to hump his hips powerfully, sliding back and forth inside her throat. He managed barely a dozen thrusts before he tensed up, sliding back and grinding his tip against her tongue urgently.

Twilight whimpered in delight, suckling at his tip, before she popped off of his member and panted hard, grinning up at him. “Cum, Shining! Cum for me!” she commanded, stroking him off rapidly with a forehoof, her gaze wild and excited. “Spill all that thick spunk in my mou-”

Once more, Shining Armor cut off his sisters begging with a harsh thrust of his cock, shoving himself into her muzzle, holding her in place with his hooves on her cheeks and thrusting violently back and forth. His flared tip ground against her tongue repeatedly, before he tensed and cried out, exploding suddenly into her mouth.

Twilight’s eyes went wide as her brother paused in his lustful humping, his throbbing tip buried against the back of her throat. The cock throbbed harder, jumping against her muzzle, and a burst of heated spunk filled her mouth instantly. Twilight whimpered in delight, her furled wings suddenly tensing and straightening, quivering in place as she tasted her brother’s spunk spilling across her tongue, her eyes wide and staring into space. Repeated bursts of gooey mess splashed across her tongue and the back of her throat, dribbling rapidly from around the embedded cock, drooling down her chin, spilling from her mouth in rapid bursts to spill onto the floor.

Gasping, Twilight tugged back, panting for breath, the last of Shining’s spurts spilling across her face, marking her cheeks and muzzle with his mess.

Shining Armor came back down to earth slowly, staring down at his little sister with wide eyes. Twilight was panting as well, whimpering and shifting slightly in place, rubbing a hoof between her legs. Her face was marked with her brother’s spunk, and her open mouth showed a slick pool of gooey cum on it. Twilight shuddered and swallowed, before panting again, her tongue poking out, now clean.

“You’re a mess,” Shining Armor panted, staring down at her with a low groan.

Twilight looked up at him with narrowing eyes, her wings fluttering faintly as she ground her hooves firmly against her drooling cunt. “It’s just liquid pride. Now I want you to fuck me.”

Shining Armor stared for a few more moments, licking his lips as he tried to catch his breath, motioning towards the bed.

Immediately, Twilight stalked over to the bed, and pulled herself up onto it, lifting her rump into the air, tail twitching to the side in invitation.

Shining Armor gave a growl of delight, stalking up behind her and pushing her rump up a little higher with his hoof, before pushing his muzzle against the exposed, dripping sex and burying his tongue in it.

Twilight whimpered, her legs quivering and wings flaring again, fluttering faintly. Her forehooves gripping at the bed as her hindlegs trembled, and she moaned softly back at her brother. “Yessss...”

Shining Armor growled lustfully, tonguing against her a little harder, a hoof lifting to squeeze her rump, spreading her open for him. His tongue ground up against the now-exposed inner flesh, making his sister whimper and bite down on her hoof in delight.

With a quick twist of his hooves, Shining Armor pushed his sister over onto her back, grinning up at her over her stomach. Twilight shuddered and squirmed in place, her wings flexing and then splaying out flat to help her balance as she stared down at him, eyes narrowed with lust. “I need you to fuck me, Shining.”

“Don’t want any more of my magic tongue, little sis?” Shining Armor asked innocently, dragging another heated lick across her drooling cunt.

Twilight arched and gasped, biting at a hoof again to stifle her noises. “Shining, if you don’t crawl up and fuck me right now, I swear to the goddess, I’m goi-eep!”

Shining Armor once more cut his sister off by dragging a firm lick across her exposed cunny, laving his tongue heatedly in a slow swirl right up over her clit, before clasping it with his lips and suckling firmly.

“You’re so much more aggressive as a princess,” Shining Armor said with a sly grin up at her.

“Fuck me already!” Twilight demanded, reaching down with both forehooves and gripping his mane, dragging him up her form, before she clasped him with both sets of hooves, grinding herself against him in earnest.

Shining Armor grinned at his sister’s aggression, leaning down to kiss her chin and throat lustfully, shifting his hips to grind his eager cock against her stomach.

Growling, Twilight wrapped her hooves around his neck and then leaned in, whispering pure filth into one of his ears. “Shiny... I want you to fuck me. I want you to rut me into the bed until I’m a quivering pile of unicorn flesh drooling your spunk from my well-fucked cunt. I need it!” Twilight punctuated her demand with a heated grind of her drooling cunt along the underside of his stiffened rod. “Shiny... please fuck me!”

Shining Armor stared down at his lust-addled sister, his eyes wide and his heart pounding. He ground his hips against her slowly, deliberately working the base of his stiff member against the slick outer lips of her sex, his tip throbbing against her chest. His forehooves reached forwards to press down on her wings, rubbing and massaging them heatedly.

Twilight groaned aloud, her entire form spasming as she shuddered and bit her bottom lip, trapped under her big brother as he ground against her teasingly. Her forehooves lifted, capturing his cock, holding it against her chest as she curled and found his tip with her lips again, fastening over the end of it and nursing at it almost urgently.

Shining Armor whimpered in delight, staring down at his sister as she suckled on the very end of his member and ground her slick cunt against his underside at the same time, her wings splayed wide.

With a low groan, Shining Armor pulled back from her muzzle once more, sliding himself free of her lips reluctantly. “You can have some more after I fuck you into the bed,” he promised, grinning down at her.

Twilight gave a coy smile at that, her eyes narrowing as she splayed her hindlegs further. “Fuck me, big bro. Fuck me hard and spill all of that gooey cum deep inside me.”

Shining Armor shuddered at his sister’s words, his ears pinning back and eyes narrowing down at her. He slid back, letting the thick cocktip slide across her stomach, the flared tip dragging through her fur until it fell neatly into place against her. Gently, he began to push forwards, grinding the flared cocktip against her drenched entrance.

Twilight started getting impatient immediately, grinding her hips up against him. “Shiny... fuck me, please!” she pleaded, squeezing her hooves around him and pushing her hips towards his throbbing cock. “Don’t be gentle, just fuck me! Rut me into the bed!”

“You are so fucking filthy,” Shining Armor growled down at his sister with a lustful smile, grinding against her a little harder.

“Fuck me!” Twilight demanded, shoving herself towards him.

With a mighty thrust, Shining Armor managed to sink his tip inside her, both of them gasping as the flared flesh forced her open around it. Wasting no time, Shining Armor bounced forwards and thrust even harder, making Twilight arch and cry out in delight as he suddenly forced two thirds of his stiff cock deep inside her.

“Yes!” Twilight cried ecstatically, so loudly that Shining Armor was glad the room was soundproofed. “Yes! Yes! Fuck me! Rut me, big brother!”

Shining Armor growled heatedly, gripping around her middle with his hooves, deliberately rubbing against her wings as he buried his nose against her throat, lipping and biting heatedly at the tender flesh there. He drew back and thrust hard, starting to fuck his little sister with a firm, urgent motion.

Twilight’s wings splayed and fluttered against the bedsheets as her brother fucked her hard. Her tight cunny clenching rhythmically around him, squeezing and milking at his thrusting cock, the soft sound of her immense moistness echoing throughout the room, mingled with the siblings pleasure-moans and the soft impact of firm thrusting.

Shining Armor panted hard as he stared down at his little sister, whimpering in delight, his forehooves pressed hard against her wings, forcing them into the bed.

“Don’t hold back!” Twilight gasped out, squeezing him hard with her hooves and grinding her hips towards his motions. “F-fuck me! Fill me!”

A low groan left Shining Armor as he gripped Twilight harder, hooves digging into her sides as he began to thrust into her with a frenzied, urgent motion.

Twilight whimpered and pushed back at him, biting her bottom lip again, panting breathlessly. Her soft, moist depths squeezed around him, clenching around his flared cocktip and making it hard for him to withdraw, before squeezing and suckling in earnest to welcome him back inside with each inwards thrust.

“T-twily... h-hahh...” Shining Armor tried to warn, his ears pinned back and teeth baring, his hips shoving against her own in a rough motion, hooves tugging her against him over and over again.

“Y-yes! Yes!” Twilight cajoled, squeezing him with her her forehooves and grinding her rump into his crotch urgently. “Fill me! Fuck me! F-fuck me and spill it all inside!”

Shining Armor clenched his teeth, and then gripped Twilight, holding her firmly in place and then thrusting wildly. Twilight’s form no longer rocked back and forth, held firmly in place by her brother’s powerful muscles, forcing the princess to take each thrust until every single millimetre of her brother’s aching cock was buried deep inside her clenching cunt.

Twilight was the first to succumb to the pleasure, crying out and spasming, her wings twitching feebly and her head throwing back as she screamed her delight to the ceiling. Her already-tight depths became impossibly so, squeezing and clenching around him wildly, milking him for his essence.

Shining Armor only last a few more thrusts, baring his teeth as he rutted his sister, sinking deep inside. He didn’t even break his rhythm, thrusting jerkily as hot bursts suddenly spilled from him. A gooey cascade of pony spunk burst deep inside Twilight’s squeezing cunny, splashing across her inner walls, coating her soft depths in her brother’s sticky essence over and over again.

With a low groan, Shining Armor continued to thrust, each firm thrust causing a wave of gooey white liquids to splash from around their joined bodies, making a mess of their hips and tails. Shining Armor misjudged his next thrust, and his throbbing rod skipped out of Twilight’s clenching body, ending up sandwiched between them, a burst of cum splashing right into Twilight’s face.

Twilight jerked back in surprise, her eyes widening in surprise before closing on reflex, the alicorn blindly lunging forwards with her muzzle and capturing his still-spurting cock with her lips, quickly fastening on the very tip and nursing on it urgently.

Shining Armor whimpered in delight, slowly rolling his hips as his gooey spurts spilled across his sisters tongue, feeling her swallow each pealy pulse of gooey ejaculate as it came out. After the first two swallows, she stared up at him, grinning devilishly against his spurting cock as she swallowed down his essence, draining him. Shining Armor couldn’t help but give another low groan, his spurts coming to a stop.

After several long moments, Shining Armor rolled to the side and splayed out hard, panting heavily and trying to get his wind back.

Twilight swallowed once more, peering down between her legs and watching a sluggish dribble of her brother’s spunk drooling from her freshly-fucked cunt, and she grinned, reaching a hoof down to rub through the mess before drawing it up to her lips, trailing her tongue across her hoof innocently. She looked to the side at her almost-comatose brother, raising a brow. “C’mon now, Shining. I’m a big girl now, I know what I want. And what I want is not you sleeping.”

Shining Armor gave a low groan, climbing to his hooves slowly and leaning against his little sister, stroking a hoof down over her wing.

Now he had two princesses to please!

Several hours later, a much more sedate Twilight Sparkle emerged from Shining Armor’s and Princess Cadance’s chambers, brushing out her mane with a hoof.

“Thank you for the therapy, big brother. I really needed that. It was bugging me so much,” Twilight Sparkle said with a faint smile.

Shining Armor smiled warmly. “Any time, Twily. I was glad to help.”

Twilight Sparkle smiled, and then leaned forwards, pecking him on the cheek, before leaning in further to whisper into his ear, “And don’t think I won’t be back again for another dose of your ‘liquid pride’.”
