Curing an itch.

“What could be so important he would have to stray away from his duty as the ruler of the empire just to see me?” Twilight said pacing around her library’s main floor.

It had been a few days since Twilight first got the letter that was stating that her brother and the cor-ruler of the Crystal Empire, was telling Twilight something big that no one else knew about yet. Spike stood by the door staring calming at her with his arms behind his head.

“Come on Twilight, stop worrying about it. He’ll be here soon so just calm down a bit.” Spike said trying to ease her troubled mind.

“I don’t see how you can be so calm about this! Not only is he captain of the guard, he’s also a prince now! Princes just don’t take the day off and visit a town in the middle of nowhere!” Twilight said as she turned her body to Spike and gave him a crazed stare.

Spike was a bit taken back by her response but wasn’t surprised to hear her snap at him. The last few days had been hard on Twilight. She was so worried that her brother would somehow smell the scent of her male play mates on her even though she had showered almost 10 times in the last 2 days. To make it worse Twilight didn’t get that much sleep thanks to that simple letter. She couldn’t figure out why after endless hours of pondering his visit.

“Twilight, you’re overthinking this like usual. Remember that one time that you went a bit crazy and needed to find a friendship problem? You if don’t calm down, this may turn into something like that.” Spike said as he walked over to her and put his little dragon hand on her front leg.

There was that word again. Crazy. Twilight hated that word with the burning intensity of 1000 suns. She felt her body tense up and her jaw twitch as she turned to her diminutive assist with an angry stare.

“What did you just say!? Did you just call me crazy!? How many times have we talked about not using that word Spike!?”
Twilight said as her bloodshot eyes stared into Spikes worried eyes.

“I didn’t say that. I said that one time you went a bit crazy.” Spike said trying to defend herself.

There it was again. Once again she had to hear that cursed word against her ears. Again her jaw twitch and Spike started to worry as her stare got more menacing by the second.

“Listen you. We’ve gone over this 23 times to be exact. That word is to NOT be said in this library! Now unless you start remembering that rule, I’m going to-”

A knock on the door gave the crazed mare a small startle and stopped her dead in her tracks.

“Oh no…he’s here! Oh nonononono! I’m still not ready! My mane is a wreck and my eyes are bloodshot and droopy! If he sees me…Spike!? No don’t open it…SPI-” Twilight said as panic had hit her body once she heard the knock and only further when her assist ran to the door and opened it before she could stop him.

The second the door open Twilight saw the large muscular figure of her bigger brother Shining Armor. The sun shone on his bare white fur giving him the proper regal look which he had acquired thanks to his marriage. Twilight wasn’t used to seeing her big brother out of his captain armor, heck he wasn’t wearing anything formal at all! Twilight looked over him and almost felt like blushing and in fact was quite taken in by his perfect white fur along with his cerulean eyes and his neatly combed sapphire mane. Twilight wasn’t sure if it was her mind or her recent activities with all the stallions around that made her see her big brother a bit differently.

Itch.

“Twily!” Shining Armor said joyfully before he walked in and hugged his little sister.

“It’s…it’s great to see you again big brother!” Twilight said still a bit shaken by her previous dilemma but quickly discarded the thought to hug her brother.

“It’s been some time hasn’t it? Sorry this was so sudden. I hope I didn’t get you worried.” He said as he held his sister around his hooves.

Didn’t get me worried!? You nearly made me lose it!!

“No not at all! I was happy to hear you were going to visit me. I never thought you would be able to get away from guard duty to visit me. Come inside please!” Twilight said returning the hug.

“Well, I’m going to visit Rarity will you catch up.” Spike said not wanting to be near Twilight when she was on edge.

“Alright have fun!” Twilight said giving him a small glare from before while hiding it from her brother. Spike quickly ran out the door, closed it, and ran from Rarity’s shop.

“Would you like some tea? I’ve got a kettle on for us.” Twilight said with a smile as she pulled away from him.

“I would love some tea Twily.” Shining Armor answered back as he followed her into the kitchen.

So what’s the big news you brought for me Shiny?” Twilight asked as she calmly grabbed the hot kettle with magic to pour some water into some cups.

“Considering you’re my favorite little sister I thought it fair to tell you first before everypony else. Cadance…is pregnant!” Shining Armor said beaming with joy.

“What?” Twilight said stunned as her control over the kettle fell and it fell to the water.

“Are you ok?” Shining Armor asked noticing she tensed up at the mention of the child.

“I…I gotta get some towels…” Twilight said still trying to piece together what she just heard.

Before Shining Armor could say anything else, Twilight ran upstairs and into her room, shutting the door behind her.

“This…this can’t be…” Twilight said as she push her back to the door and stared at the floor in disbelief.

She knew with her studies and training she would be a princess…but with her brother and aunt having a child, she may be pushed back because of it. As far as she knew, her dreams just got shattered.

“No…I worked so hard to become a princess…this isn’t fair….this isn’t fair!” Twilight said getting angry as she slammed her hoof against the floorboard.

“What if the child turns out to be an alicorn!? Oh no…NONONONONO!!! IF THAT BRAT IS BORN WITH BOTH A PAIR OF WINGS AND A HORN I’LL NEVER BE A PRINCESS!! Sure the chances are only one out of thousand but it could still happen!! IT COULD STILL HAPPEN!” Twilight screamed in frustration as dark magic started to seep from her eyes.

All that anger was starting to boil up to a breaking point where she just wanted to unleash it at someone, anyone. Twilight started to hyperventilate and her pupils started to dilute to small little dots. Her hooves were coursing up her face to her mane making it into a wreck as she pushed it back.

“Twilight? You okay little sis?” Shining Armor’s voice rang out as he started to walk up the stairs.

The second she heard his voice, the dark magic started to fade and she was calming down. Suddenly Twilight’s mind started to flood with lust filled thoughts of her and Shining armor and at the same time snapped. She could picture herself bent over her bed, being mounted by the muscular body of her older brother. Her throat felt more dry as she pictured his meaty cock slowly sliding into her, and rocking her small body wildly. She was no stranger to seeing his dick. Back when she was young and living with her parents, it was a normal thing to see it sometimes. Back then it was all innocent family living. Now when she thought about his member, it sent a shiver down her spine.

Itch.

It didn’t help her that she was stressed over his visit and didn’t get to enjoy anybody for the last few days. But now, here she was, wanting her brother’s lean and massive frame. She could have it for herself. She could feel how a real princess felt to be bucked by him. Her dream may have been pushed back but she’ll make him pay her in so many ways... Though incest was common place around most of Equestria, it would cause quite the scandal if it was found out that the new ruler of the Crystal Empire was bedding with the star pupil of princess Celestia, let alone his own sister. If she wanted she could keep it secret and threaten to choke him with it like a hangmare’s noose. She could get away with so much more things thanks to her brother. With a big grin she turned off the lights and teleported herself to on top of her bookshelf and waited.

“Sis? Are you alright? You didn’t burn yourself did you? I thought I heard you screaming up here.” Shining Armor said worried about Twilight as he opened the door and walked inside of her room.

The room was eerily quiet and he was getting a very bad vibe from it.

“Twilight?” Shining said speaking into the darkness feeling uneasy.

With a small laugh, Twilight used her magic and locked the bar behind her brother.

“Wh-what the!? Twilight are you ok!?” He said looking to find her.

“I’m fine big brother…just fine…” Twilight said as she grinned like a cheshshire cat.

Shining looked toward her voice and when he saw her crazed grin, it made him more nervous.

“You’re starting to scare me Twi…” he asked not sure what to expect from her.

Twilight didn’t say anything and started to look over his body again. She could have it for herself…and no one would ever know…but she had to play it smart. Considering his talent was making a shield to block anything he deemed a threat, she needed to be smart. She quickly turned on the light and teleported beside him.

“Am I seriously be an auntie!? Oh my gosh! How far is she in?” Twilight said beaming with energy and putting on a false smile.

“Twily? You’re acting a bit crazy right now…” Shining said not liking her burst of oddly happiness.

At the sound of hearing crazy, her left ear started to flop and jaw started to twitch. It was bad enough to hear it from the walking purple fax machine but to hear it from her brother as well drove her even crazier.

“I uh…Think I’ll go downstairs and let you calm down for a bit…” Shining said as he turned his back to her and walked for the door.

Twilight’s false smile faded and got replaced by her catlike grin. Without a word she flared her horn up and launched the green heart at him.

“Shinnnyyyyy~” She said to him.

“What are you-“ He started to say as he turned around but was instantly greeted with the spell sinking into his forehead.

Twilight continued to smile and slowly walked to his side.On the inside, Shining Armor was greatly concerned because the spell he was under, considering it felt very familiar yet different in a way.

“Sorry big brother…you’re not going anywhere until I get my fill of you~” She said seductively as she put her hoof to the jaw and pull his chin so he was looking at her face.

“Soooo…Cadance is bearing a child is she~? Makes me wonder how much love making you did. The image of you rutting her behind is….oddly arousing for some reason.” She said as she put her face into his gut and nuzzled it.

Twilight could feel all his tense muscles against her face. Years of being the captain toned his body to perfection.

“Maybe I should make you do the same to me. But first…lay on your back…” Twilight ordered to him.
Shining Armor wanted to fight his crazed sisters spell and put some sense back into her but he had a hard time fighting it. His legs started to feel numb and then they started to move on their own. Eventually the same feeling hit his whole body and then he was nothing but a puppet being manipulated to perform for its master.

“Mmmmm…The spell is working nicely.” Twilight hissed with enjoyment as she watched his dick start to grow.

Twilight wanted more badly then anything ever before. She knew she should stop here. She knew it was a bad idea and that it could ruin their relationship forever. She had never even thought of him this way, but her thoughts were so clouded by excitement and lust that she didn’t want to turn away. With a lust filled sense of determination, she climbed over his lean body and sat on his gut and looked into his now green eyes. Her backside twitched with excitement as his large member brushed against her flank.

“Think of this as sibling love Shiny. Your little sister wants you to know how much she loves you…” Twilight said as she moved her mouth over his making touch just barely.

She could feel his warm breath beating against her lips and up her head to her horn as she kissed his chin, down his neck and to his chest. The feeling of his breath against her sensitive made her quiver with even more excitement. She started to move her kisses up to his left ear and gave it a kiss on the lobe of it.

“Mmmmm...I think I’ll enjoy you the most big brother…” She said as she started to feel very flushed and hot.
Wanting to enjoy the feeling even more, she eyeballed his long horn on his head and smiled. She read in a few books that unicorns could have magical orgasms if the horn is pleasured enough. With that thought she gently moved her body up his body a bit so his horn was in front of her face. Without a word she moved her hooves and her tongue to the base of the horn and moved her tongue upward. Even under her spell, Twilight felt his body quiver and react to his horn being touched.

“Is your horn sensitive big brother~? Does this feel good~?” She said as her lips wrapped around the edges and she moved her tongue around it like she was licking the shaft of a dick.

To her this was the best thing in the world. 2 pure blood unicorns fooling around on the floor in her room with no one coming to bug them and ruining it. She didn’t care he was her brother. The second he told her Cadance was pregnant any sort of logic she had leave got tossed out the door. She just quietly enjoyed running her lips on his horn. Deep inside Shining Armor’s mind he was unprepared to see his sister like this. Even in their youth she was always so quiet and sheltered. He never noticed if she had any affection for him at all, yet he knew it wasn’t affection. The way her body moved against his, he knew lust was driving her to have him. To him it was almost like the first time when Cadance started to get more wanting in his body in the weeks before their wedding, or the proper case of things, it was Chrysalis who wanted his body. He wanted to fight back and put some sense into his sister but the spell kept him at bay of performing any resistance at all.

Twilight continued to enjoy what she was doing. Without accidentally stabbing herself, she put the horn into her mouth and bobbed it slowly. She could feel the horn giving her warning as it poked the back of her mouth, so she made small yet erratic bobs on the tip of it. Eventually she could feel magic energy starting to course around the tip signaling her books were indeed right.

“Your little sister is about to get you off Shiny~ How does it feel~?” She said as she nibbled on the tip of it to drive the feeling further.

As if answering her question his horn started to seep raw magic into her lips. He could feel his possessed body heating up to an unbearing point, and his horn pulsed with life before it released. Twilight could feel the magic starting to come out and quickly moved her tips off the tip and to the sides of it, stroking it wildly. A few seconds later she felt a slight tingling come from it and felt a burst of magic energy come from it and launch into the air. Twilight smiled as the magic bolt of power disappeared, signaling she was successful In her task.

“Did you like that~? Does cadence ever play with your horn like that~? I’m I proving I’m just as good as she is~? Maybe I should enjoy you right~” She said quickly moved her swollen pussy to his member and started to grind against it eagerly.
The feeling of it was unreal to Twilight. she felt it throb and twitch against her begging marehood as if it wanted to go inside of her. She could feel even more heat radiating from her body and more wetness building up. Her wetness even started to make his member more smooth and ready for access. The more she rubbed against it, the more she lusted for it. Finally thinking it was wet enough to go in, she moved her tender lips to the end of it and slowly prodded the tip.

“Are you ready Shiny~? Your dick that Cadence gets to enjoy every night is about to go inside of me~ we’re about to commit the act of incest dear brother and there’s nothing you can do about…oh gosh! Itttttt….” Twilight said as she pushed her hips back and felt the massive member start to enter inside her body.

Twilight moaned in ecstasy as his twitching massive went deeper and deeper into her body. She couldn’t believe what she had just done. Here she was, on the floor of her room, with the body of her brother below her, getting penetrated by his large mass. The itch in her loins was finally getting relief after two days of stress and barely any sleep. To her, sex was the perfect remedy and she would get the remedy no matter what.

“Come on big brother~ Let me feel you buck my pussy non stop~” Twilight ordered to him.

Shining Armor continued to try and fight her spell but nothing was working for him and then he felt his lower body start to thrust upward sending his quivering mass even deeper into her. Twilight again moaned in ecstasy as the large member slid in and out with no resistance at all. The thrusts started a bit short but quickly got a good pacing going and even went deeper and deeper until she could feel his balls slapping her ass.

“How does it feel big brother~? How does it feel to have your big cock inside your little sister~? Does it feel good~? Does it feel good that your little sister has you under her spell~? Does it feel good to be under this spell again~? It’s a little familiar isn’t it~? Let’s just say your little sister decided to fuse both Chrysalis’s mind spell with your loving wives Want It Need It spell~ I’m pretty sure Celestia told you about my little incident some time ago with that spell Cadence taught me~ Do you like it~? I’ve been exploring the use of the spell around town and I love it very much. But do you know what I love more~? That my BIG brother is rutting away at my pussy with no hesitation at all~ Maybe once you fill me up, I’ll keep your seed inside of me just to spite you for making Cadence pregnant~ Do you know how hard I worked to earn my spot as the first student of Celestia’s to become an alicorn~? If the royal couple end up having a child, I’ll be pushed back because of some brat! I was so close to earning that spot but you had to knock up my aunt and ruin that dream for me. I can easily make it seem like your little visit to Ponyville was nothing more than to share a tender moment with your little sister that went too far. I can easily make it look like you raped me big brother~ what would happen to you then~? What would happen if my little Spike came home and hear his mother figure screaming from the bedroom~? I can make your life miserable big brother…” Twilight said as her brother shamelessly rutted away at her backside.

“T-twi…” Shining said still trying to fight the spell.

“hehehe. You can’t fight my spell Shiny. I’m a prodigy among unicorns. I’m gifted in all forms of magic and should be in line to become the next princess of Equestria. Now rut your little sister harder!” Twilight shouted as she put more power into her spell knowing he couldn’t fight her magic.

With that said Shining Armor’s thrust went faster and harder into her. Twilight loved how her small body was being rocked on top of his. She eventually moved her hooves to the floor so she could brace herself to feel even more of him inside of her. She loved the sound of his dick violating her backside the way it was. It was so good her mind began to get hazy and clouded, and soon the sound of it faded into nothing. She could feel her loud moans escaping her throat and her face flushed red. She loved her sense of power over the ruler of a kingdom. To think she has the power to bring her own brother on his back and more obedient then Spike when a gem stood in front of his face. If she could have her brother, she could have any pony at all. Maybe she would target her teacher for a night of passion and sex. Or maybe Luna, the princess who spent nearly 1000 years trapped on a moon with no one to comfort her at all. No pony was safe from her undying lust.

What felt like hours, which actually had been minutes, Twilight felt her brother going as fast as he could go. Her senses finally started to return after being lost in the passion of it all. Twilight wished she could turn her head just to see the twitching cock slamming in and out of her without pause. She wanted to see his balls slapping hard against her ass. She just wanted to look and forever remember the dirty scene playing out. She wished she had a camera around just to make that idea a reality.

“You’re about to cum inside of me big brother. It feels wrong doesn’t it? But you don’t have to worry about me getting pregnant. You can finish up inside of me without feeling horrible for this act of passionate incest~ Do you hate me now~? Do you hate me for what I have become~? Your once sheltered innocent sister who you never thought would do something as vile as this now eagerly awaiting for the grand finish~? You may hate it…but I love every second of it~” Twilight whispered as she moved her face down to his and spoke against his lips.

Right after say that to him, she felt her orgasm building up. She could feel her body tensing up and her legs shaking uncontrollably. She felt her moans getting more erratic and louder with every thrust that erupted from him. She didn’t have to worry about holding back her pleasure. The upside to having a treehouse for a home meant your neighbours houses were a good 20 feet away because of the branches from it.

She quickly shut her eyes and started to push her body back into his already thrusting member. She wanted this orgasm to be her greatest one ever, one to remember forever. She could feel her breaking point quickly starting to hit her. Eventually the sensation hit and she just held it in for as long as she could. She pushed her body against his and for the last few seconds her mind became like a raging ocean on a stormy night.

“So close…oh gosh so close!!” She moaned into his neck.

A split second later both orgasms met. Twilight’s eyes shot open as she stared at the wall taking it all in. To her it was the greatest feeling ever. To Shining Armor it was vile and disgusting to know he just climaxed into his younger sibling and couldn’t do anything about it. Twilight felt her body relax and her head went down and rested on his chest. Her breathing was heavy and the scent of sweat and sex filled her nose. She loved the feeling of his seed dripping out her backside as she slowly moved her body off of his member. For the time being that itch had been dealt with. Even though she knew it would return, she was still satisfied for the time being.

“You truly are the best big brother a little sister could ever have~” She said softly as she moved her mouth up to his and locked lips with him for a few seconds.

She didn’t want to move from her spot on top of him. She wanted to stay like that forever and keep her brother to herself. She just laid on his chest and started to think of a plan as she pulled her lips away from his.

Twilight had her plan figured out. She would simply clean up the mess and make it look like he hadn’t arrived yet. All she had to do was make sure no one was watching her put him outside the door and lock a few extra memories of seeing Spike from before. It wasn’t full proof but it was all she could do because of her reckless actions. She wanted to see what would happen if she set it up to look like she got raped but went against it. For now she would lock the memories and if she ever wanted to enjoy her brother again, she would simply go and visit him and use the memories to her advantage. She didn’t want this to be the only time she got to enjoy the vile act of incest. In fact the thought of getting Cadence involved in a 3-way even went through her mind.

Twilight quickly grabbed some cloths and cleaned up the lovely little pool of cum that mere minutes ago were her greatest pleasure. She could notice Shining Armor’s massive member slowly going down at the corner of her eyes. After the mess was gone and the cloths discarded into the laundry basket, she turned her attention back to him and a small tune formed in her head.

“My little Shiny, My little Shiny~ I used to wonder what incest could be. My little Shiny, My little Shiny~ until you shared all of its magic with me.” Twilight whispered into her brother’s ear before setting her plan into motion.
