Shining Armor slowly awoke from his slumber as sunlight shined in through the glass pane windows of the Crystal Castle's royal chambers. He opened his eyes slightly, and brought his hooves up to his eyes to rub them. Blinking, his eyes slowly adjusted to the bright light, and the prince yawned loudly. He cracked a small grin, glad that it was a new, bright day and threw the sheets off of him as he got out of bed.
However, he winced as his body was immediately met with cold air. His pristine, white coat went rigid and stiff as the temperature difference took his comforting heat. Nevertheless, he adjusted to the room temperature and finally planted all four hooves on the sparkling crystal floor. He stretched out his legs, each one popping as the gases left the respective joints in his legs. He then stretched his neck a bit, and felt relieved as the tension in his neck muscles left him. He looked over to his bed again, and his sister and wife were still sound asleep, cuddling in a cute, warm embrace.
And then the pungent aroma hit him. His nostrils finally took in the scent that had been in the throne room since the previous night. As the sweet, strong smell of sweat, cum, and sex registered in his brain, he began to remember. He remembered that his sister came to the Crystal empire on what she told Spike was "royal business". However, it was entirely the opposite when Twilight had arrived late into the night. After being escorted to the crystal throne room and being left alone with Princess Cadence and her brother, she forced Cadence into a deep embrace. Cadence was all too happy to oblige the sensual greeting, and soon after Twilight tackled her brother and tongue kissed him.
This was somehow all that was necessary to get the rulers of the Crystal Empire aroused, and no explanation was needed as the trio made their way to the royal chambers. Once inside Cadence and Twilight had jumped onto the large bed and had yet another lesbian embrace. This time, however, Shining's sister started to dry hump the other princess. The pair moaned as Shining had sat next to them, stroking his large member, which was equally as happy as he was to see his sister again.
In a flash of pink, the Princess of Love had grown herself the stallionhood she used on Twilight just about a year ago. Twilight, being a very horny princess, eagerly watched in awe as it grew in size and hardened. Once fully erect, the Princess of Magic toyed with it. examining it in her hooves like a studious filly who had just discovered alchemy. Her brother watched the scene play before him, and couldn't suppress a gently laugh as he figured his sister would even treat sexual contact and interaction as a study session. He wouldn't have put much thought into it before, seeing as the last time they had done this, she was spellbound by Cadence.
However, this time was an entirely different story. While spellbinding another living being is in fact a way to have them do your bidding, the spellbound individual has complete control over their senses. Although Twilight couldn't control her body during the time, she could certainly feel every touch and sensation given to her. That fact being present, she most likely gave into her carnal desires after their escapade a year ago.
And that's all Shining could really remember. The rest of the night was a complete blur of pleasure, cum, and moaning. All Shining could truly think about now was the exact thing he knew he was forgetting. It was something about this time of year. Something about the chill in the air. In order to collect his thoughts, he turned to the large doors that led to a balcony that looked over the entire Crystal Empire. He smiled st the thought of getting fresh air, and slowly trotted over to the doors, his hoofsteps breaking the silence and tranquility of the bedroom.
He pushed the doors open and recoiled slightly as pure sunlight invaded his retinas. One he had adjusted for the second time this morning, he moved forward and looked out over his kingdom. Only now did he realize it was snowing outside. Small snowflakes landed across the Crystal Empire in a haphazardly fashion as Shining tried to recollect his thoughts. Could it be Wednesday? He was sure he had something to do Wednesday. Something important involving the market district, perhaps? No, it had to do something with this snow, he was sure of it.
He finally remembered that it was near that time of year again. He had been so busy with royal matters lately that he had forgotten that it was December! His mind was immediately filled with some regret of this recollection, as he hadn't gotten anypony close to him a gift yet! Not his mother, which he usually got her some writing supplies. Not his father, which he usually got him a new telescope for his research. For his younger sister sleeping not fifty feet away from where he stood, he could get away with getting her a few books. As for his wife, he still had no idea what she would truly want for Hearth's Warming this year. She had been dropping hints for the past few weeks, but he shrugged those off.
He leaned over the balcony slightly, still deep in thought of how to attend to the upcoming holiday. He was interrupted as he felt somepony draping over his back.
"Hey Big Bro!" Twilight said with a giggle. Shining turned his head to see his sister, her mane a mess and her eyes lazily open.
"Oh, hey Twiley! Did you sleep well?" Shining asked as his nostrils were flooded with a strong smell of sex. All of this suddenly felt odd to him. Like somehow this should have never happened. He remembered how his sister was a year ago, and how she wasn't entirely a sexual deviant. Now, instead of her studious self, she seemed to be craving sex constantly. Granted, she is deprived of it when she has no special somepony of her own, but he couldn't help but think of what drove her to come to the Crystal Empire for a incestuous fucking.
His thoughts were cut off again as his sister kissed him. Every thought of how this was wrong was instantly replaced of how this was right! He leaned into the kiss and Twilight opened her mouth to lash out her tongue. Shining did the same, and soon the two were tongue kissing sloppily. They inched closer and closer back into the royal chambers, and once inside, hopped back onto the bed, not breaking their kissing session.
In the heat of the moment, Twilight had grabbed her older brother's hoof and trailed it down her body, all the way to her dripping sex. Shining couldn't help but think of one thing to do, and so he broke the kiss and began rubbing his sister. she gasped lightly, and a tiny whimper escaped her as her eyes closed shut. Shining felt good for giving her such pleasure, and started kissing her neck, trailing down her body till he found her hot marehood against his chin.
Twilight spread her legs open, allowing Shining easier access to her pussy. Looking at his sister's perfect looking snatch, he inhaled deeply, the sexual scent increasing his actions with fervor as he gave her a slow lick from the bottom of her slit to her clit. She moaned loudly, and pushed Shining's head deeper into her muff.
Meanwhile, Shining was in heaven. His sister's pussy tasted like salt and sugar, and he licked her slit faster, darting his tongue in the soft flesh of her inner labia.
"Don't be shy. Eat me." Twilight said, moaning again in delight.
As Shining took the hint and darted his tongue into his sister's slick opening, he heard the sheets rustle next to him, and his wife slowly awoke.
"Do the two of you have to be so loud?" She said, blinking a few times before laying down to watch the incest loving before her. Just then, Cadence heard a knock on the bedroom door. With her magic, she slowly opened it, only for a fully armored guard to saunter in slowly, remaining completely emotionless to the scene before him. He trotted up to the side of the bead where the prince was, and cleared his throat so he could speak up correctly.
"Sir, I have important information for you." The white guard said in a strong and firm tone.
"Give me a second." Shining said, looking towards the guard as his sister slowly raised her voice, approaching orgasm at an alarming rate to the guard, who stood completely emotionless to the scene.
Just then, Twilight screamed as her orgasm hit her, and shining was greeted with a torrent of his sister's sweet, juicy marecum. Shining eagerly lapped up what he could as it flooded his mouth. Some spilled out around his muzzle, but he didn't care. Twilight was panting heavily after her intense orgasm, and lay there completely limp.
"Yes, what is it?" Shining asked the guard as he lifted his wet muzzle from his sister's muff and turned his head toward the guard. The guard's face was still emotionless.
"I didn't mean to bother you at this time, Sire, but your parents are here to see you. They said they had something important to tell you, and that you should come at once."
"What? My parents?" Shining thought to himself as the guard slowly left the room formally.
"Lucky fuck." The guard mumbled as he left the royal chambers and down the stairs.
