Heat of the moment

View Online

The house was quiet, only the sound of honey nut oats being chewed filled the air. The mid-morning sun was already present, covering parts of the kitchen in broken sections of light, courtesy of the large glass windows. Sitting at the kitchen table was a lone stallion, casually munching away at his breakfast, while he fought to keep his eyes open.

Shining Armor grumbled, his head constantly throbbing thanks to a study session from the previous night that went on longer than it should have. Thoughts of guard protocols and regulations flooded his mind, while at the same time images of flasks and beakers tried to fight for his center of attention. He hated studying for exams and usually just coasted by in school thanks to him having a better understanding than most, but sadly certain subjects and failing grades made him put in more effort. He wouldn't have cared otherwise, but the idea of attending school for an extra year because he was short one credit wasn't something he didn't want to deal with.

Guard duty and security took over his mind as mundane thoughts of positions, salutes, and general duties played out. He hated the constant stream of thoughts, but thankfully not as much as his school ones. It was a future he was setting himself up for. He was already guaranteed a guard position, thanks to his father being Captain of the Royal Guard himself, but Shining knew he had to show the effort and drive to become that as well. He just wished both school and his guard pony exams didn't fall under the morning and evening of the same day.

Thankfully it was a few days away, and he instead focused on the fact it was a weekend. He usually slept in, enjoying the blissful respite from a long week of schooling, but this week he wouldn't get that. He continued to eat and struggled to keep his eyes open, but he stayed focused enough to read over a letter left for him by his parents. It was short and simple; both his parents had to tend a royal summit up in the castle and they apologized for having to drop foalsitting duties on him. They also took Spike for special reasons, so it would be one less sibling to worry about. He didn't mind it, since they always paid him for it, but he wished they would hire a proper sitter so he could enjoy the small amount of time he had off.

He didn't foalsit often, thanks to his mother being a stay-at-home parent, or even the fact that his younger sibling was usually up in the castle with the princess, eagerly studying magic under her wing. Sadly thanks to the royal summit, the princess was preoccupied and unable to teach, and though his mother was usually home, she generously offered to help prep for it, thanks to her old occupation of working within the castle itself.

His thoughts went to his sister. She was young and very book smart, and though they had a very active childhood together, she was slowly starting to grow out of the usual activities they did. She was growing up, showing more interest in a magical academic pursuit in life, and most of the time she was at home, she usually stayed in her room or in the house library, studying spells or reading up on Equestrian history. She was a shut in and didn't go out much, but from what he knew, she had a few friends she mingled with on occasion. Nothing concrete though, which was worrying in a way, but Shining himself wasn't a social butterfly either. Both ponies kept to themselves and opted to pursue their life goals from their own comfort zones, and both just happened to enjoy that from the comfort of their own homes.

The sound of hooves dragging across the floor filled his ears and a loud yawn quickly followed. He grew more alert but he didn't look behind him, knowing very well it was his sister.

"Morning, Twiley," Shining mumbled, trying his best to not sound miserable from his lack of sleep.

"Morning, Shiny," Twilight replied, her voice sounding like she didn't get a good night's sleep either. "Where's Mom and Dad?"

"They took Spike and left early to attend the summit, since a dragon emissary is visiting," Shining replied as he took another mouthful of oats. "It's just you and me until the evening."

"Oh," she spoke, her voice filled with worry, as she trotted past his seat. "I guess I can't go to the doctors anymore."

Shining went quiet as she walked by, and he couldn't help but notice she was frantic yet awkward in the way she walked. Her mane she always combed was bedridden and stuck off to the side, and her tail constantly swished almost in an impatient manner. Her breathing was slow and heavy and a hint of perspiration covered her whole body, making it shine with a wet glow. It almost looked like she showered, yet thanks to her mane being completely dry, he knew something was off.

"Are you feeling okay?" He asked as she opened the fridge and magically grabbed a jug of milk and an apple.

"Think I'm coming down with something," she replied with uneasiness in her words. "Woke up feeling all hot and sweaty, so I'm wondering if I got a fever of some kind."

"Did you sleep well last night?" He probed further, hoping to get answers or hints to what was wrong with her.

"I slept fine," she told him as she poured a glass of milk and put the jug back in the fridge, before trotting to the table to sit. "I just woke up feeling… off."

"Off?" He quoted.

"Yeah, I just don't feel myself today," she replied as she neared. "It's not depression or anything, it's just my whole body feels weird in a way I can't describe it."

Shining stayed quiet, trying to make sense of the situation. He stared a few seconds longer, taking in her appearance as his thoughts drifted. She recently went through a growth spurt and no longer looked like a filly. She was still young, being the ripe age of fourteen, and she was starting to blossom into a proper mare. She was still small though, and being a stallion that was almost fully grown himself, he still towered over her.

His mind took notice of the more particular parts growing, specifically her flank, legs, and her butt, but he shrugged it off as if it was nothing, doing his best to silence the more lewd machinations of his teenage mind. He wasn't immune to his heterosexual thoughts, considering he dealt with females in school often, but he knew better than to look at his sister in that same light.

Shining continued to watch and hoped he could figure out what was wrong with her. It wasn't until she started to hoist herself up on the chair that made the gears in his mind start to turn. He watched her expression cringe and tense up as her rear came into contact with the smooth surface of the wooden stool. She stifled something under her breath and her lips trembled for a moment. Something clicked in his mind and his groggy mind jolted fully awake. He knew that look on her face, something he saw a lot of in school just before spring break hit. Mares would come to school with that same frantic and awkward step, and when they sat in their seats, their expressions were the same as Twilight's currently was. Sometimes they would moan and sometimes they would remain quiet, but Shining knew exactly what was wrong.

His sister was in heat.

He continued to stay quiet and he could tell his sister was starting to get confused by his awkward silence. He didn't know what to say, but his mind screamed at him, telling him to leave and lock himself in his room. Being around a female in heat was never a situation he liked to be in. It was awkward and uncomfortable, especially at school. Most of the time the mare would distance themselves from others, hoping they wouldn't give into the temptation of the situation, and thankfully most of the times they were successful.

Sometimes though, it got so bad that mares would have to go to the nurses office to be dealt with. He didn't know what they did, but when they returned to class, their heat cycle was gone. The answers were always mixed; some mares said they got rutted into oblivion, while others said a spell of some kind was used. He knew the latter was more likely, but in the back of his mind, the former interested him more. He wasn't oblivious to the topic of sex. Though he never engaged in sexual activity with others, he had a basic understanding of it.

He let out a deep sigh and started to breathe in through his nose. He instantly regretted it as a familiar scent started to fill the room. He knew that scent well, an unpleasant sensation that triggered something in his mind. He looked at Twilight who was focused on drinking the last bit of her milk, while his eyes caught sight of her tail. Even from her seated position, it stood upright, constantly fanning and flickering about, accidentally spreading her scent. The more it spread, the more anxious he grew, and eventually he swallowed back a building tension in his throat as he felt his loins start to stiffen.

"You should try laying down a bit longer. Maybe you didn't get enough sleep," he answered finally, hoping to distract himself before lewd thoughts started to surface in his mind. "Or try having a cold shower."

"I don't know, but I think you're right," she replied, as she put the empty glass down and grabbed her apple. "What do you think is wrong with me though?"

Shining didn't want to answer that question, knowing very well the answer to it. It wasn't out of spite, but rather the fact she was oblivious to the situation. He feared telling her she was in heat would cause her to panic, and she had a tendency of overreacting to things when something didn't go her way. He didn't want to deal with it, at least not alone, and the idea of making sure they didn't linger around each other for most of the day became present, as well as another thought. She was young but considering her age, it shouldn't have been her first heat cycle. She would have experienced her first cycle last year, and thankfully he didn't have to deal with it then. He just wondered why she was acting like she didn't know. Maybe she was trying to not let him see it; maybe it was all an act, or maybe it was something else. He wanted to probe her for answers, but as the scent started to become much more prominent, he knew it was better to not stick around her.

"I'm not sure, but I can head to the library and look something up," he replied, trying to figure out an excuse, while at the same time he did his best to appear confident. "There may be a spell I can find or some sort of explanation to what's wrong with you. While I do that, you should go shower and get some rest. Just let your big brother figure something out for you."

Twilight said nothing and stared quietly at him. For a brief second, he wondered if he pushed too hard to be away from her, but as a warm smile appeared on her face, he knew otherwise.

"Alright, I'll go get some rest," she replied, her voice no longer carried the uneasiness it did prior. "Thanks, Shiny. You're the best."

Shining smiled in return and watched his sister raise from her seat. Her expression tensed as she moved but she quickly composed herself as she began to trot away. Still holding her apple with her magic, she took a bite, and Shining couldn't help but notice a small sashay in her hips as she walked. It felt off to him and he closed his eyes, fearing his mind was working against him. When he opened them back up, she was walking the same way as she came into the kitchen earlier. He started to sigh, loathing the state of his sexually active mind, but lost his breath as her rear came into focus. As she moved under one of the broken beams of light, her back end glistened and he quickly looked away. What he saw wasn't a machination of his mind but instead was something very real.

He squeezed his legs together, trying his best to forget what he saw, but it only got worse as he clinched his eyes shut. He saw that crystal clear image floating in his mind, taunting him as the sight of a very aroused mare's nethers dominated him. A very wet and puffy vulva stared back, voicelessly clamored to be filled and sated, while an equally wet and winking clitoris yearned to be touched and caressed.

Twilight left the kitchen, the sound of her hooves beating against the floor faded as she went deeper into the house. He opened his eyes and took a deep breath, letting out a sigh shortly after. He gave his head a shake, and the image began to fade and distort until he let the thoughts from his study session early on start to play out. Eventually the image faded from existence and he breathed a sigh of relief. He stared forward, his eyes unfocused as he stared off into nothingness. All the times he had to deal with a mare in heat, he was told to ignore her. He wanted to, but with him and her in the house by themselves, it was going to be tricky. Coupled with the fact that he had to watch over her and that they were going to be alone until the evening, made Shining dread the day. He hoped and prayed the library had something to fix the situation he was in.

He looked down to his bowl and noticed a few oats and milk were left on the bottom. Two oats remained, one half broken while one end of it overlapped into the round hole of the other. He stared and grumbled at the image, before he lifted the bowl with his magic and drank down the rest.

"It just had to be one of those days, didn't it?" Shining asked himself, grumbling as he looked down at his lap, noticing he was no longer stiff. "Well… better not waste any time and start searching."

Tick, tick, tick…

The constant monotonous tick of a clock filled the otherwise quiet library. Periodically the sound of hooves brushing against the carpet of the oval room played out, along with the frustrated groans of the stallion inside of it. Shining continued to search the endless amount of books in hopes he could find something related to dealing with a mare in heat. He had no such luck, even with the vast collection of spells at his disposal.

"Why don't we have anything on this?" He groaned as another book came to a close.

Shining stopped, realizing he was talking to no one but himself. Taking a deep breath, he looked up as he laid the book on the floor and saw he still had a large portion of the library to explore. He already cleared two full shelves and saw he had another eight to go.

He grabbed another; a book titled 'A Beginner's Guide to Body Alterations' he was even more hopeful than before. Holding the book, he sat himself down in a large blue bean bag cushion and began to read. A lot of it was interesting, but mostly insufficient. There were spells covering size alteration, mane and coat hair extending, and even a spell that could alter his voice, yet even with a book covering body spells, he came up fruitless with an answer to his question.

He looked up at the clock, noticing an hour had passed since he first arrived. His already tired mind grew more tired by the second and it started to show. A mild headache had formed and Shining groaned as he clenched his eyes shut, before he rubbed his forehead. His frustrations started to peak, and in a fit of anger, he chucked the book at the shelf from whence it came.

"What did that book ever do to you?"

Shining opened his eyes as a familiar voice filled his ears. He knew it was his sister right away and he tensed up completely when he saw her enter the room. Her appearance was much the same, but he noticed her mane was more of a mess than before. What was once bed hair, now looked like she had been constantly rubbing her mane backwards while twirling a bit of it with her hooves. It looked like a wreck that reminded him of a bird's nest. He would have laughed if he wasn't afraid of the situation he was in.

"I thought you were resting?" Shining asked, noticing her face looked more flushed than before.

"Body is still acting weird and it's only getting worse. Now it feels hot and itchy back... there," she answered as she winced and raised her back leg, before she rubbed her thighs against each other. "But why are you throwing books around and why is the library a mess?"

Shining looked around and saw most of the books he searched were either sprawled about aimlessly or stacked up awkwardly.

"Sorry, been trying to find a spell to help you," he apologized as he looked away. "Kinda getting frustrated with finding nothing though."

"I appreciate the effort, but at least keep everything the way it was before," Twilight huffed with annoyance as she started to return the books to the shelves. "You know how Mom gets when everything is unorganized."

"Sorry, you're right," Shining sighed as he watched her put the books away.

It went quiet and Shining looked to the untouched shelves, until he noticed she had her back to him. He quickly looked away but not fast enough to notice a wink from her swollen clitoris. He cringed and felt his lower body react again and his nose picked up her scent. It smelled much more potent and knew it would drive him mad if he had to stay around her. He opened his mouth and began to breathe in through it, in hopes her scent wouldn't be as intense.

"You have any idea what's wrong?" He asked randomly, as he grabbed another book with his magic.

"Well… while I was laying down, I started to remember something," she answered, without looking back at him. "This isn't the first time I've felt like this."

"When was this?" Shining cocked his brow but kept his eyes on the book.

"Around the same time last year now that I think of it," she answered quietly, before she spoke louder. "It was the same feeling as now. I went to Mom and told her how I felt, before she cast this weird spell on me."

"What did the spell do?" Shining's ears perked and his eyes widened.

"I don't know how to best describe it," she began. "It cooled me down in a way and the itching feeling was gone. I asked her what she did and though I don't remember her exact words, she said something along the lines of fixing a problem all growing mares deal with."

"Did she tell you what the problem was or what the spell was?" Shining asked with growing excitement in his voice.

"No," Twilight replied in a sullen tone, which caused him to sulk back in his cushion. "I was hoping I could find the spell somewhere in here, but without a name, I don't know what to look for."

Shining sighed, as he grew more frustrated by the minute. Knowing a spell existed that suppressed her heat was great to hear, but without the spell itself, it amounted to nothing. Even with that, Shining had to take another positive note from it. It wasn't her first heat and knew it was better to tell her about it, instead of playing the fool in the matter.

"I think I know what's wrong with you, Twiley," he spoke up, which caused her to turn around and look at him with a growing smile on her face. "Did Mom ever tell you about estrus?"

"Estrus?" Twilight tilted her head and gave him a puzzled look. "I haven't heard that word before."

Shining grumbled, knowing he had to be the one to explain it to her. In all honesty it didn't surprise him, considering school didn't teach him about it until he was fifteen. He just wished his parents would fill her in.

"It's what's happening to your body right now," he began. "It happens to mares every year around this time once they're old enough. Your body gets hot and you feel the need to… umm." He stopped, a bit of embarrassment started to show on his face.

"Umm, what?" She replied.

"I don't know how to be subtle about this, but… wait, different question first," Shining started, but changed his line of thinking half way through. "Have you ever had urges?"

"Urges?" She asked as she grew more curious.

"You know, the urge to rub yourself in a way," he answered sheepishly.

"Rub myself? Why would I need to rub myself?" She asked in return.

"Okay, different approach," he sighed. "How about the urge to put something inside of you?"

"You mean eating? Shining, I'm not hungry if that's what you're suggesting." Twilight puffed her cheeks out at him, almost like she was insulted by the implication.

"I can't be subtle about this can I?" He groaned as he looked to the ceiling.

"Subtle about what? Why don't you just say it?" She rebutted, her voice started to fill with anger. "Just tell me what estrus is already!"

"Fiiine, I give up. I'll just say it: Twiley, you're in heat and your body is horny!” Shining whined loudly.

"Horny?" Twilight blushed as she started to reach for her horn.

“No, not that type of horn. Ugh, since you don't know what sex is, you probably don't know what an orgasm is either right?" Shining asked, growing flustered and very annoyed.

Twilight shook her head no.

"That hot and itchy feeling you're experiencing is your body telling you that you are horny and that you need an orgasm, a release of sexual tension. The best way to do it is to either rub yourself or have a stallion or even a mare do it for you," he answered fully as he sank back in his cushion and sighed. "The first is called masturbation and the second part is called sexual intercourse; it's the equivalent of a male and female loving each other in a more romantic way."

"Oh? Ooh! Is that what it's called?" Twilight replied in an excited manner. "I've seen ponies doing that!"

"Wait, what?" He replied, shocked to hear that revelation. "It wasn't Mom or Dad was it?"

"Eww, no," she replied with disgust in her expression. "Why would you get that idea?"

"Just a random thought," he lied as he blushed at an old memory of seeing his father face deep in his mother's privates one night as he was going to the bathroom. "Where did you see it?"

"Well," she started as her already flushed face grew more red. "During one of my overnight visits with Celestia, I snuck out of my room to explore the castle. While out, I happened to see something that sounded like what you said."

"Go on." Shining grew more intrigued.

"I saw a guard pony and a maid pony hiding near the garden and the maid was," Twilight stopped and looked away as she crossed her back legs. "I saw her sucking his… umm, what's it called?"

"His penis?" Shining answered, unamused.

"Yeah, that! She was sucking it because it was all hard and pointy. His penis was all 'horny' so that's what you meant right?" Twilight asked, her voice too innocent for the words she conveyed.

Shining didn't know to answer that for a second, but she was technically correct, if not slightly awkward in her portrayal of it

"Uhh y-yeah, you're right actually. How long did you watch them?"

"Not long. It made me feel weird as I watched it, and it's kinda how I feel now, just it was nowhere near as bad," she answered before she stopped and looked at him with a nervous look on her face. "Are… you going to have to do that to me? I mean, I don't have a penis, but are you going to have to stick your face where it's all hot and itchy?"

Shining tensed up, the conversation going in a direction he knew would happen, but subconsciously hoped it wouldn't. He wished he kept quiet and with her popping the question, he knew it was now a 'Make or Break' situation. The way he wanted it to go was to say no and hoped he could find a spell, but his perverted mind and body were saying otherwise. Thankfully his morals outweighed his foolish desires and he stayed strong.

"I can, but I can't," he replied, and he was sure he saw her expression sink into disbelief. "I'm sorry, Twiley but two ponies who are related can't do this. It's called incest and lots of ponies view it like dark magic. It's forbidden and taboo, and Dad told me if you ever go into an estrus cycle when he's not home, I'm supposed to lock myself in my room."

"But dark magic hurts ponies both physically and mentally. Is incest supposed to hurt?" She asked.

"No, sex isn't supposed to hurt but, it's frowned upon because incest can lead to… complications."

"Complications?"

"Look its hard to explain, but Dad told me that I can't have sex with you."

"B-but… why would they leave me home with you if they knew this would happen?" She asked, visibly confused.

"Ponies don't go into a heat cycle this early in the year," Shining noted that it was a week earlier than the usual cycle hit. "Plus they had the summit on their minds for the past week and they must have forgotten about it."

"So what am I supposed to do? Wait?" She asked further, frustration started to surface in her voice. "I don't think I can wait all day until they come home."

"That's why I'm trying to find a spell to fix this mess," he replied as he floated a book in front of him. "If I can find a spell then I can make it stop."

"Okay but… we could just… do it and not tell anyone," she replied meekly, almost like she didn't want to say it herself. "It's just us and if you can make it go away, then we don't have to search for a spell."

"Twilight, we are not having sex!" Shining answered back, red faced and embarrassed. "Mom and Dad will kill me if they found out about this!"

"But it's really bad!" She whined as she fidgeted her back legs. "Plus they won't know about it. I won't tell, I promise!"

"That's not the point!" Shining snapped back, as she jerked her body back out of fear for the level of anger in his voice. "Sorry… but I'm scared I may knock you up if we did it."

"Huh?" Twilight asked.

"Ugh, do you know where foals come from?" Shining asked as he brought a hoof up to his temple and rubbed it.

"Oh. Celestia told me a big heron-like bird delivers them to moms and dads in the night!" Twilight replied with a chipper tone in her voice. "But what does that have to do with anything?"

Shining stared forward and his mouth hung open. Normally he would have corrected her on the spot, but the fact that she stated Celestia told her that complicated the matter. Twilight was a mare that looked to Celestia like she was a living god among ponies and every word or fact that she stated was right and absolute. If Celestia told her a pig could fly without magic, she would believe it. If Celestia said two plus two equals five, then Twilight would find every book stating otherwise and try to change it. Shining may have been her older brother that she admired, but when compared to Celestia, it was like comparing an ant hill to a mountain. He wouldn't win the argument even if he tried.

"Forget I said anything," he replied, almost forcing himself to bite his tongue in the process. "But my point still stands; we aren't having sex. You just have to wait."

"And my point also stands; we won't tell Mom or Dad," Twilight spoke back, as a stubborn expression appeared. "I don't wanna wait! I want it now!"

He loathed her stubborn attitude and barely ever had to deal with it, yet whenever it surfaced he almost always gave into her demands. He had one card up his sleeve though, and knew he had to play it.

"Twiley, don't make me evoke the rule of Sibling Supreme," he told her as a confident smirk appeared on his face.

This time it was Twilight's mouth who went agape and she knew she wasn't going to win the argument. Whenever there was a fight, whoever had the crown of being the supreme sibling, would automatically win all arguments. Fortunately he was the current holder of it and he could tell she wasn't happy with it.

“What? Why? That’s not fair!” she snapped at him as she stamped her hoof into the ground.

"Yeah well you’re acting like a brat!” he snapped back. “Look, I know you’re not feeling well but we are not having sex! Now, I'm going to continue searching and I want you to go to your room," Shining ordered as the scent from her body now clung to both their coats.

Twilight went quiet, stamped her front hooves, and sat her haunches on the ground. Even with her sensitive backside bothering her, she didn't wince or show it in her expression.

Unfortunately Shining started to hit his limit with the situation. His own body was starting to feel hot and thankfully the conversation kept his mind off of sexualizing his sister, but he felt it start to slip. He wished it would stop, he wished she would not try to argue with him, and he wished he didn't have to foalsit his sister because his parents were too lazy to hire a proper sitter.

"Go to your room," He ordered with a stern intensity that made Twilight lean back.

She refused regardless.

“NOW!”

He breathed heavily as he stared at her, the corner of his mouth trembled and his teeth gritted. He was unaware of how angry he looked and for a few seconds he wasn't sure why Twilight looked at him with confusion on her face. It wasn't until Shining heard her let out a sob that he quickly calmed down.

She let out another, but he could tell she was trying to hold back. She continued to stare at him with angry eyes and her lips started to tremble as time dragged by. He felt bad but he didn't know what to say to her. He knew he had to do something but he couldn't muster up the resolve to do anything at the moment, until finally his words returned to him.

"Hey I didn't mean-"

Twilight cut him off and huffed loudly at him before she turned around and began to trot away. Her backside greeted him again but his mind was too fixated on her expression. She didn't look back but as she reached the door, Shining watched her expression sink into despair and sadness. He felt his heart sink and it felt like gravity started to crush his very soul. He made his sister cry, something that he promised he would never do to her. It hurt more than anything and he wanted to apologize to her, yet the words didn't come. Only the sound of hooves transitioning from carpet to tile flooring played out.

"Why does this gotta happen to me?" He whined loudly as he dropped the book, his mind a jumbled mess.

He felt like crying himself and got ready to throw his face into his bean cushion, until the sound of a door slamming echoed from the hallway. He looked up and knew he would have to fix the problem he caused. He didn't want to go near her but he couldn't ignore what he just did. If anything, he would apologize for his actions and continue to search the library. He couldn't let her stay mad at him all day, fearing the repercussions of it, but he also feared going near her. He was at a crossroads with his mind, frantically debating going left or right; do as his parents instructed and wait it out, or be a big brother and apologize for what he did.

Finally after a few minutes of mental anguish, he looked up at the clock and noticed the numbers had returned. He looked down to the book and saw the magic circle return as well, which caused him to relax.

"I can do this, I'll apologize and then continue to search for the spell," he spoke to himself, in an attempt to bolster his confidence. "Just go in, apologize, and go out. Quick and easy; nothing can go wrong."

He took another deep breath and stared at the doorway. He smiled weakly and began to walk to Twilight's room.

Fools Rush in

Shining stood outside the door to his sister’s bedroom. On the other side he could hear the muffled sobs, almost belittling him for his outburst prior. He still felt bad and he kept his head low, feeling more shame than anything as he slowly began to raise his hoof. It stopped before it came into contact with the door.

He looked up and stared at the smooth oak before him, knowing very well that every instance of her scent he experienced before was going to be nothing compared to what waited for him inside. He swallowed back and wanted to turn away, hoping to carry on with his endeavor to find the spell he needed.

Another loud sob played out and a very needy whine followed. His body tensed and he felt blood shoot to his lower body, causing him to fidget his legs in an effort to shut down what would follow. He wanted to stick to his morals and did his best to rationalize his actions, as he took a deep breath and relaxed his body. In and out, less than a minute hopefully. Just apologize, comfort her from a distance, and continue on. It was wishful thinking, but he frantically clung to the idea that fortune would favor him, but in the back of his mind it wasn’t going to be as easy.

“Twiley?” he knocked on the door, his voice filled with concern.

“Go away!” she snapped back, her voice a broken mess of anger, frustration, sadness, and horniness.

“Twiley, please. I… I just want to apologize,” he replied as the door inched open, thanks to the door not being properly closed.

Shining stopped as the scent nearly floored him as it came from the open doorway, causing him to almost reel back. He kept himself steady, but it was as he feared. Her room reeked of sexual frustration and as the door continued to open, it only got worse. The scent was thick in the air and for a few brief seconds he found it impossible to inhale through his nose and quickly started to breathe through his mouth.

It didn’t get any better. As he breathed he felt a warm sensation in his chest, a similar sensation he got when he snuck out one of his dad’s alcoholic beverages from the special mini fridge he usually kept locked. It was a warm buzzing feeling and for some reason it relaxed his body and mind, and that sensation was eerily similar to what he was feeling now. It wasn’t until he gave his head a shake and looked around that he broke from his stupor. Now in full view of her room, Shining could see a large lump under the covers of her bed, signaling she was hiding herself under them.

“Twiley, please come out,” he started as he took a step in and quickly found his body almost moving on its own accord. “Look, I know I shouldn’t have yelled at you like that or even evoke the rule like I did. I was wrong to get mad at you. I was being selfish and I wasn’t looking at things from your point of view.”

She didn’t reply but he heard movement from under the covers as she adjusted her body. He wondered what she was doing, until her head poked out and her eyes locked onto his. With her now visible, Shining’s heart sank as the sight of her red and puffy tear filled eyes stared at him. Her lower lip was trembling but thankfully she stopped sobbing as she continued to listen to him.

“You’re in pain, and I can’t even imagine how your body feels right now. Even worse I went and told you the best way to deal with your heat cycle was with another pony… and when you looked to me for that help, I got mad at you for it. I’m sorry, sis.”

“I was very confused,” Twilight spoke up, as she brought up a bit of her blanket and rubbed her face against it, ridding the unsightly tears from her eyes. "And I'm still confused as to why you can't do anything."

“I should have made an effort to explain things better… it’s just, being around a mare in heat does things to stallions that make everything very uncomfortable,” he finished as he looked to the ground out of fear at looking at anything around the room.

“It does?” Twilight asked as she tilted her head. “What’s it doing to you?”

Shining said nothing for a moment, fearing the answer he wanted to say. How could he say it? How would a big brother tell his little sister that his perverted sexually starved teenage mind was subconsciously provoking him? He had to be simple and blunt with the topic, and knew it would be better to just say what was wrong with him.

“It makes me horny as well,” he said as his face reddened and his expression twisted into an uncomfortable one. “But it’s not right to be horny around you.”

“Why?” she asked.

“Siblings can’t have sex, I told you this already.”

“But why? You said it’s like dark magic, but I don’t see the resemblance. You said it’s not going to hurt, and if it's the best way to stop this pain in my body, then you should just stop making it out like it's a big deal.

Shining cringed, wishing he could just say that sex will lead to pregnancy and that Celestia told her a lie. That unpassable hurdle stopped him and made things complicated.

“Besides I’m still confused why you think sticking your face where it’s hot and itchy is a problem,” Twilight added nonchalantly.

Shining stopped his thoughts as her words took over. It could have been the scent in the air, or it could have been his frustrated mind, yet something clicked. His biggest fear was accidentally impregnating his sister, and he always viewed sexual intercourse as simple rutting. He never considered other ways of tending to her, and for some reason, even with his early memory of seeing his parents in bed, while Twilight brought up she saw a mare giving a blowjob to a stallion, it never clicked… until now. Sure the thoughts were dirty and very unfitting for a big brother, but the idea of tending to her heat cycle, without actual sexual penetration was becoming a dominant thought in his mind.

It still felt morally wrong; the thought of going muzzle deep into her, but the thoughts in his head twisted and turned about, pushing him to many different ideas. Masturbation was definitely a thing and he wondered if she bothered to try it.

“Twiley,” he spoke up, causing her to stare back quietly. “Have you tried rubbing yourself yet?”

“Yes,” Twilight blushed. “But it’s super hard to concentrate and it only feels worse when I touch myself."

Shining cocked his brow, something didn’t seem right. Maybe she was doing it wrong and though rubbing one off with hooves wasn’t really the best feeling, it did the job for whenever Shining got horny.

“How are you rubbing it?” Shining asked.

“Umm… should I just show you?”

Shining tensed and knew what he got himself into. There was regret, as his initial plan started to crumble to pieces, and there was another rush of blood to his groin. He didn’t move, nor did he clench and flex his loins, hoping if he ignored it, the rush would go away without being provoked. He knew he was just prolonging it, knowing very well once she showed him how she was tending to herself, his body would betray him fully.

His mind kept telling him to leave, but he found his body already taking control of his actions. He sat his haunches to the ground, took a deep breath and stared forward.

“Go for it.”

Twilight said nothing and quickly pushed the thick covers off her sweaty body. The scent got worse and his stallionhood started to poke out of his sheathe. He cringed and tried to ignore the feeling, but as Twilight turned her body around and raised her rear to him, he felt his resolve crumble.

Shining expected her to be bad, but she was even worse. She was wet, almost soaked partially down her thighs as she presented herself. Her vulva was red, puffy, and clenching the air around it. Her clitoris was swollen, and constantly winking from her aroused state. It needed relief very badly, and there would be no way she would last the whole day without something to sate her.

Twilight lowered her upper body to the bed and jostled her back legs, allowing her to slip one hoof through. Shining watched further and heard Twilight gasped as the edge of her hoof brushed against her slit, before it moved off to the side. She began to rub on the outside of the swollen area and Shining knew why she wasn’t feeling any better.

“Is that how you’ve been rubbing it?” He asked.

“Yeah, it hurts to touch myself where it's sensitive,” she replied as she looked back.

“You gotta rub where it hurts the most though. Once you do, then you’ll be able to release that tension,” Shining noted matter-of-factly.

“But every time I touch it, I get this tingly sensation that makes me feel weird.”

“That’s normal. Once you start rubbing it, that sensation is your body telling you to keep going, and the more you rub it, the bigger that feeling is going to get.”

“Oh… okay, but it’s also exhausting as well and I’m already tired from trying. What did you think I was doing after breakfast?” Twilight’s voice filled with a hint of annoyance.

Shining went quiet, forgetting that he was in the library for quite some time prior. Of course she would have been coping on her own and he failed to consider that possibility earlier on.

“Can you… show me how to do it properly then?” Twilight asked as she looked at him with a begging expression. “Plllllease?”

Shining said nothing.

“Please!” She begged further, her voice almost turning into a yowl as she swished her tail at him, fanning that dreaded scent even more.

Shining sighed, knowing he put himself in a corner he couldn’t get out of anymore. If he said no and left the room, she would get more upset with him and their relationship would get even more strained. He tried to be a good stallion, but he couldn’t say no anymore to her. He had to stop looking at it from his point of view and focus on hers. Though it wasn’t what he wanted, it's what she needed. As long as it didn’t lead to him mindlessly rutting her then everything would be fine.

“Alright, I’ll help you. Just… promise you’ll never tell Mom or Dad.” Shining broke as he bit his lip.

“I’ve been making that promise since we were in the library,” she replied as she gave him an annoyed frown.

“I know, I’m sorry,” he sighed as he stepped forward but stopped as he felt that familiar sensation in his groin.

His sigh deepened as he fidgeted and he felt more stiff than he cared to be. It was to the point that ignoring it wouldn’t calm him down and looking between his legs, the head was already starting to poke out. He hated it, but as he looked back up, he blushed as Twilight was now turned around and staring between his legs.

“You’re getting horny right?” she asked innocently as she tilted her head down to get a better look at it.

“Please don’t look at it,” Shining told her as he moved closer and started to climb onto the bed.

“But I haven’t seen one up close.” Twilight puffed out her cheeks before she huffed at him for smothering it in the sheets. “Besides I thought I was supposed to suck on it.”

“Twilight, I’m here to help you,” he replied sternfully as he sat upright on the bed, before he grabbed the blanket and covered his lower region. “I can deal with my horniness by myself.”

“Can I at least look at it?” she asked.

“Why?” he replied stoically.

“I’ve only seen it that one time and in books. What’s wrong with letting me look at it? I showed you my privates so why can’t I look at yours?”

"No."

"Please? Pretty please?"

“No means no, so stop asking.”

Twilight huffed again but didn’t argue with him. He was thankful for it yet he still wished his impending erection would go away. He could tell she was sexually interested in him, but he refused to give in, hoping to keep it as pure as possible and pray a hoof was all it took. He hoped if he got her off quickly enough, he would leave and rub one off in the shower.

“Come rest your back against me,” he told her as he crawled backwards to the headboard and rested his back against it. “Lean against my stomach and try to avoid sitting on my… you know, penis.”

He relaxed his body and Twilight quickly crawled to him as he did. Leaning himself against the headboard so he could get comfortable, he kept the blanket loose and cozy so it didn’t overly rub against him. He only kept his stallionhood covered and once Twilight was close enough, she started to shimmy herself so her back was against his stomach. With her touching his body, he could feel how hot and sweaty she really was. Her breathing was labored and he could see her looking down at her nethers with bated anticipation. He jostled his body once more and her head rested against his shoulder, allowing him to lean his head forward far enough that she could rest her own head against his cheek. Her breathing slowed and she looked at his eyes with a silent neediness before she rubbed her cheek against his.

“Please make it go away,” she begged quietly as her legs spread open for him.

“I will, I promise. Just take a deep breath and relax for me,” he replied as he brought his left hoof up to hers. “The first bit may be a bit intense, so hold my hoof.”

She nodded and wrapped around his, holding it tightly. He could feel the uneasiness in her body as she did so, and knew she was trying her hardest to not look worried. As uneasy as she was, he could feel the trust in her grip, and it helped him to continue on.

“Twiley?”

“Yeah?”

“If it gets too much to handle, just tell me if you want me to stop, okay?”

“Ok.”

She took a breath like he asked, and her body relaxed against his, allowing him to not feel so uneasy himself. Looking down he saw that wet patch and wasting no time, he moved his free hoof downward.

The reaction was instant and as he brushed against her clitoris, her legs fidgeted close, her lower body arched forward, and her eyes slammed shut. The grip of her hoof tightened and Shining moved his hoof away, causing her to move her lower body back.

“It's a lot different when somepony touches you, isn’t it?” Shining asked as Twilight nuzzled his cheek once again.

"Mhm hmm," Twilight mumbled as she bit the bottom corner of her lip.

“I’ll try a bit lower.”

Shining reached down a bit more and brought the edge of his hoof against her wet fillyhood. He got the same reaction, but it wasn’t as notable and he kept his hoof still as a soft gasp left her mouth. He kept his eyes on her face, looking for any reaction that warranted him to pull away as he began to slowly stroke. He saw her lips trembling and he felt her grip tighten even more around his hoof, but he didn’t stop, even as she closed her eyes.

“Not as bad?” Shining asked as he moved his hoof back and forth ever so slightly.

“It… feels good actually,” Twilight replied, her voice a mixture of pleasure and relaxation.

Her body relaxed further as he continued to rub; his movements were a circular clockwise motion, allowing him to spread out the pleasure through the entire outer area. As he moved his hoof, her hips gyrated in tune with it. It wasn’t excessive, but her motions were fast enough that her butt constantly rubbed against his lap. Her movements were accompanied by soft moans and periodic gasps as the edge of his hoof slipped in a bit more than he wanted to. Her eagerness and her constant moans played on Shining’s mind and he felt his erection suffer for it.

He couldn’t keep it down, no matter how hard he tried. Eventually his erection grew to full length and made a tent with the covers. As it grew, Twilight got more excited in her movements and her eyes opened and stayed trained on it, causing Shining to blush hard and focus his efforts on getting her off faster. He tightened his grip on her hoof and moved his other hoof up against her clit. A loud gasp escaped and Twilight looked to his face.

“Tell me how good this part feels.” As the words left his mouth, Shining pressed his hoof hard against her clit and began to rub very quickly.

Her body tensed, her eyes went wide, and her head craned up, while her mouth went agape. A loud and carnal moan came from her and her hips jerked forward, inadvertently pushing his hoof harder against her sensitive nub.

“That feels- that feels… a-ahhhh,” she panted loudly, unable to put the intense feeling into words.

Her body rocked in tune with his hoof and her hips gyrated to the rhythm he had established, yet as she rocked her body, it slowly started sliding down his stomach. He did his best to ignore the aching feeling in his neglected erection, but a sudden rush that warranted him to flex it caused Twilight’s butt to almost lean against it. It continued to ache and throb as the soft covers smothered it, and as Twilight kept her eyes on it, she started to look like she was becoming infatuated with its appearance.

“I’m going to go a bit faster okay?” Shining warned her as he pushed both his and her hoof to her chest, allowing him to hug her closely.

She didn’t reply but she nodded in acknowledgement, before the first of many broken gasps started to play out. He did as he said, and pushed harder while rubbing faster against her clitoris. Her free hoof quickly shot to his and Shining thought she was going to stop him, until she opted to rest it against his, almost in an effort to guide it. Her gasps grew louder and her body writhed with absolute pleasure as her already intense scent seemed to grow thicker. She was close and considering how pent up she was, Shining was surprised she was holding out for so long.

It didn’t take long though and as Twilight let out a notable moan, Shining watched her clench her eyes shut and bite her lower lip intensely. He felt her body stiffening against his and even found her hoof urging him to go as fast as he could against her clitoris. He waited, longing to get her off so badly and rid her of that treacherous heat cycle, and eventually his efforts paid off.

She came hard and she let off a moan so loud, it played throughout the whole house. Her body went rigid and Shining pushed his hoof back against her slit in an attempt to stop her from dirtying the blanket more than it already was. He moved his hoof slightly to the side by mistake, and looked down as a squirt of white liquid shot from her nethers and hit the blanket covering his erection. As the initial spurt left, smaller ones followed. Her pussy clenched at his hoof, almost like it was trying to draw it in as she came, and Shining watched a thick white stream of cum flow out, running against both his stomach and the blankets.

“Looks like I did it,” Shining noted, feeling a sense of pride in his actions.

“That- that feels so much better,” Twilight sighed loudly, her heart racing as she looked down at the mess she made. “Is that what the relief feels like?”

“Yeah, it’s even more intense when you hold it in for as long as you can,” he told her as he brought his tired hoof up and stared at the glistening wetness covering it. “Never thought I would say this, but did you enjoy your first orgasm, Twilight?”

“It felt great… but I am still very hot and itchy,” Twilight replied.

Shining instantly grew worried. He assumed one orgasm would be able to sate her heat, yet he didn’t expect she’d still need more. As he thought about what to do, his thoughts were cut as Twilight grabbed the blanket covering his erection and tugged at it.

“H-hey, what are you doing?” Shining stammered, scared she was going to remove the covers.

“I’m just cleaning the bit of… Whatever that white stuff is, off your stomach,” Twilight replied as she sat up. She made an attempt to wipe up the mess but stopped as his erection let off a rather noticeable twitch. She let go of the blanket and moved her hoof away as she once again started to stare at the tip of the erection poking upward.

“You shouldn’t use your blanket to clean it,” Shining told her, but found she was too preoccupied with his erection. “Twilight?”

Without warning, Twilight lit up her horn and lifted the edge of the blanket off his erection.

“Twilight!? What are yo-ah!” Shining shouted as he panicked, his lower body slid forward, causing his back to rest against the bed.

He quickly reached for the blanket, only to accidentally push Twilight forward. Her lower body slid as well, allowing her lithe frame to rest on his chest, giving him a full face view of the vulva he just rubbed. That pungent scent hit him full blast and Shining went silent as a bit of cum Twilight failed to wipe up, dribbled onto his chest. He stared deadpanned, that winking clitoris still begging for more attention, but his mind focused on something else entirely.

Lower down his body, Shining almost felt his heart stop as the blankets were now off his stallionhood, allowing Twilight to see the shameless pink and black moted erection before her. She didn’t say anything, but Shining could see a smile on her face that very much reminded him of a pony discovering something new and exciting. Her face mere inches from his cock, Shining could almost feel her labored breaths beating against his sensitive flesh.

“Is that what it looks like up close? Oh wow,” She spoke quietly as his cock let off a hard twitch before a bit of precum seeped out from the tip.

Shining said nothing, shocked and embarrassed that the erection he tried so hard to hide was now in full display. He wanted to speak, but only found his mouth trembling and failing to produce any form of speech. He only further watched as she twisted and turned her head, letting her inspect it, while at the same time leaned in close to the tip and began to sniff.

“It smells weird but it smells good at the same time. I don’t know how to describe it, but for some reason it makes me feel even hotter,” Twilight said quietly before she turned and looked at Shining. “It looks like it hurts, though. Does it hurt right now?”

“A-a little,” Shining replied without realizing it. “But you shouldn’t be looking at it.”

“What’s wrong with me looking at it?” She asked in an annoyed tune. “If this is what it looks like when you’re horny then you should do something about it.”

“I’ll take care of it after I'm done helping you,” Shining replied as some of his nerve returned to him.

“Or… I could help you as well,” Twilight replied as she gave him a coy smile and began to move her hoof.

“Wait! Please, Twilight, don't touch it-eet!” Shining stammered out, only to find his words cut off as Twilight’s hoof touched the tip of his erection, causing it to spasm at the touch.

“It’s not fair that you should only help me, Shiny,” Twilight replied as she wiggled the tip back and forth gently. “Plus I really wanna try sucking it.”

“This isn’t right,” Shining muttered as he cringed and tensed at the feeling, causing his body to jostle.

His movements made Twilight’s lower body slide even more back, to the point that she was now laying on his body. She may have been smaller and lighter, but Shining felt like he was pinned to the bed.

“Please can I try sucking it? Hey! While I suck it, you could try to use your mouth on me!” Twilight noted with excitement in her voice as she brought her second hoof and rubbed it against the medial ring of his penis.

Shining groaned at the touch and wanted to deny her request, but he found himself unable to fight the idea of it. Her touch was too good to ignore and his erection voicelessly screamed at him for relief of any kind, even more so wishing she could do it for him. It felt wrong, filthy, disgraceful, and yet he wanted relief more than ever.

“Alright, fine. You can suck it,” he replied, finally breaking. “Do you remember how the maid did it?”

Twilight didn’t respond, instead her eyes closed as her body quivered. He heard her take a deep breath through her nose, no doubt enthralled by his own scent, before she grinned and opened her mouth. Shining watched quietly as she stuck out her tongue and gave the tip of his cock a firm lick, which caused him to stifle a groan and restrain himself from mindlessly bucking his hips forward. He didn’t get a chance to say anything before Twilight moved both her hooves to the head of his erection, holding it in place as she began to lean more forward.

A soft ‘ah’ left her throat and her lips gently latched onto the edge of his erection, that caused Shining to let out a sigh, and leaned his head back. He stared at the ceiling, while the sight of her tail swished about in his vision, mesmerizing him until he felt her tongue swirl around the edge, eagerly lapping up the mixture of precum and sweat covering it.

Her hooves started to gently stroke the sides of his stallionhood, never applying too much pressure to the sensitive flesh as both her mouth and lips continued to explore his endowment. Her head began to move downward and her head turned to a sideways position, allowing her lips to move effortlessly with her. She stopped at the middle of his cock, planting her lips on his medial ring, before a soft moan left her throat, letting her lips vibrate against it. A deep sigh of approval left his mouth as shuddered breaths followed behind, before she started to run her mouth back up to the tip.

As he laid there taking in the feeling of it, Twilight gave her rump a shake, causing him to refocus on it. Her legs parted more and Shining knew she was trying to coax him into using his mouth on her.

"Come on," she whined, "I still feel hot down there, too." He still had a bit of uneasiness in his system, but the sight of it was too good to ignore.

Slowly, Shining brought his hooves up and placed them against her flank. She cooed into his erection and a gasp quickly followed as he pulled her back just a bit. Her mouth left briefly but she was quick to crane her neck forward and latch back into it. Her lips took in the whole head of it, and Shining felt her tongue start to run circles around the edge. It pushed him on and craning his own neck in return, he placed his muzzle against her inner thigh.

His nose was greeted a bit of almost-dried arousal, and he instantly noticed a watermelon scent to it. It smelled fruity, sweet, and he was sure there was a hint of apples in it as well. It reminded him of their snack they had before bed the previous night, and Shining wondered if Twilight tasted as good as she smelled.

“It’s gotta feel cold for a second,” he warned as he trailed his nose along her leg before he pressed it against her slit.

She let off a small moan and her body tensed at the touch, but she was quick to relax as he began to nuzzle her pussy. It didn’t last long and a small gasp left Twilight as Shining moved his tongue out and brushed it against her slit. It tasted just as he thought, yet it was sweeter than he imagined. It was like a distilled and thick fruity cocktail that made him want it even more of it as he brushed his tongue harder against it. Her lips left his erection and a louder moan came out as she looked over her shoulder to watch him work.

Having eyes on him, Shining focused his efforts and gave her a long and pleasurable lick. As he came to the top, he moved his tongue away and gave her another lick, making sure to start at her clitoris before going up. The tip of his tongue touched her clit, causing it to wink repeatedly and made her moan even louder. He moved it up again, making sure it was slow enough that she could feel every bit of it touch her wetness.

Shining wiggled his own hips in return, wanting her to continue her blissful motions on his erection. She caught on quickly and turned back to the aching erection before taking the head of it back in. She couldn’t take it far in, but Shining wasn’t going to fault her for it. Both were inexperienced, but it worked in Shining’s favor. He was able to explore and poke his tongue around to see what made her body tick, and she was able to enjoy his cock as much as she wanted.

She started to bob her head, taking a good inch of it in her throat and though he worried she would push herself too hard for his pleasure, her hooves came up and stroked in tune with her bobs. Her strokes were long but quick, moving to his medial ring before she trailed back up. The feeling was great but he wanted to return the favor even more. He moved his face away from her nethers, before his hooves came up and rested at each side of her slit. He pulled them apart, letting his eyes stare into the hot crevice that awaited him.

As they parted, Twilight’s rear clenched the air around the opening and wasting no time he stuck out his tongue and dove right in. Another carnal moan echoed into his erection and Twilight took a bit more of his cock into her throat. Her lips sucked harder on the tip and in return Shining brought his mouth against her slit; letting his tongue wiggle about, while he was able to caress and coax her outer lips. The taste of her insides were intoxicating and he regretted he put himself off for some long on acquiring it.

“That… feels good but weird.” Twilight broke her menstrations, allowing herself to speak. “Can you do what you did before and rub that one area?”

For a moment Shining was confused by her words and pulled away getting ready to ask. He stopped as the sight of her clitoris caught his eyes and he instantly knew what she meant. He waited for another wink and when it showed itself, Shining dove in and kissed the nub.

“Yeah, like that,” Twilight cooed as she resumed her blowjob.

He felt it wink against his lips and tongue, letting Shining gauge it. He wrapped his lips around it, and started to swirl his tongue in a circular motion very similar to what his hoof was doing prior. Every action was rewarded with a moan from Twilight and he felt her putting more gusto into her bobs. The feeling was enjoyed, but with his nose resting against her folds, Shining found himself more into that end.

He put more pressure into his tongue, letting it to circle faster while he periodically flicked it against her clit. Every flick was rewarded with a soft buck of her hips and Shining quickly figured out that stimulating her clit was the key to getting her off very quickly. He was relentless with his tongue and his actions excited Twilight so much that her vagina was seeping arousal. His nose constantly brushed against her slit, letting the lubrication from within drip onto his nose. The scent was maddening, but it fueled him to go hard and fast against her.

Even with the constant torrent of licks and flicks he gave her, Twilight never ceased her movements on the opposite end. Never taking it too deep, Twilight had long since been able to suck and coax just under half his length. Missing his medial ring by an inch, Shining was amazed she was able to get a good grasp on how to suck a cock so well. Her teeth never touched, her bobs were well paced, and her tongue constantly rubbed against his erection. Even with her being a book smart shut-in, she was a natural in the sex department.

Her pace started to falter as Shining relentless tongue lashing started to take effect. Her bobs slowed and her hooves weren’t able to apply constant relief to him. Sure he was close but not close enough to warrant his focus. If anything, knowing his tongue was delivering her to a second impending orgasm filled Shining with a large sense of pride. It made him go faster and harder against her, wanting to make her second climax just as great as the first. He kept the pleasure going, making sure it was so intense, Twilight couldn’t help but moan and pant till her mouth left his erection completely. He felt her body tighten up and he noticed her head turn slightly, allowing him to see her face. She was gritting her teeth and her eyes were clenched shut. He was close to finishing her off. He could sense it and as a soft groan escaped her throat, Shining knew he once again flipped that climactic switch.

Her body tensed again and she tightened up, while her mouth trembled and fought to suppress the coming moans. A small splash of cum hit his muzzle and he watched her fillyhood clench and convulse before his eyes. As it trembled he moved his tongue up and gave it a hark lick, causing her mouth to open as a pitiful whine of sexual relief rang out. He felt her wetness tremble harder against his tongue and he kept it in place, allowing him to feel the throes of her orgasm come to a close. The trembling stopped, her moan died down, and Shining felt her body relax against his body as everything started to wind down.

“How do you feel now?” Shining asked as he pulled his tongue away and gave his lips a quick lick.

“That felt just as good as the first time,” Twilight answered in a single haggard breath. “Is it supposed to feel as good?”

“I think so. Stallions usually are sexually satisfied after one orgasm,” Shining noted as he looked at his still hard erection. “I’m not sure if mares are easily satisfied though. Do you still feel hot and itchy?”

“Definitely not as bad as before, but I feel like I could go again,” Twilight replied as Shining stared wide-eyed at her.

“Wait… you’re still horny?”

“I think I am,” Twilight replied as she shaked her rump at him. “That’s normal right?”

“I- I honestly don’t know,” Shining said, unsure of what to say to her. “I always thought mares only needed one orgasm to be pacified.”

“Pacified?” Twilight asked.

“Sorry. Meant to say cooled down. Like I said, stallions usually need only one to cool down,” he answered as Twilight slowly turned her eyes back to his erection.

“Oh, then you’re still horny too, right?” Twilight asked as she leaned up and remained her face to be level with the tip of his erection.

“Yeah.”

“Can I continue sucking it?”

“Do you want to continue?”

Twilight paused as she licked her lips.

“Sure, I really wanna see what your orgasm looks like.”

Shining paused as he stared at the dripping fillyhood before him.

“Alright, just get off me for a moment so I can get cozy.”

Twilight rolled her body off his and Shining took a deep breath in, before he pulled his upper body up and rested it back against the headboard. Once settled, he relaxed his body and let his back legs spread out, letting the cool air brush against his wet sack and shaft. As he spread himself out, Twilight watched with eager anticipation until he patted the pillow at his side.

“Come sit beside me?” he asked.

Twilight wasted no time and moved the pillow, before she laid on all four of her legs, while she sat upright. Her face was almost level his which caused her to look up at him. He stared back, smiling as genuine trust and affection was very present in her expression. As he stared, she began to lower her mouth towards his waiting erection and once she was close enough to it so he could feel her hot breath beat against it, Shining relaxed and leaned his head back, while looking up at the ceiling. She didn’t say anything to him, but as she brought one hoof up to the wet tip of his shaft and began to softly stroke it, he brought his own hoof up and stroked her mane. The touch was brief as his hoof moved down her neck and eventually stopped just before her shoulders. She snuggled closer to his body and Shining heard her take a deep breath as he waited for the eventual touch of her lips once again.

The touch came quick and as her mouth wrapped around the head of his erection, she moaned softly into it. Her tongue gave one hard lick across the tip of it, before she quickly followed up with another, and then another, until her licks became very reminiscent of a pony licking a lollipop. As she licked, she brought her second hoof up to his erection and lined it up with her first hoof to quickly resume where she left off prior with her strokes. Her head stayed in place while her hooves tended to him nicely, the feeling of her eagerly licking the head of his cock was too good to push away for the moment. She circled the head with her tongue, occasionally stopping and giving the tip a teasing lick, almost like she was trying to gauge some kind of response for him. He couldn’t ignore the oddly sensational feeling as every hard lick made his arousal spike little by little, and every hard movement he felt, he let out a groan and bucked his hips forward out of instinct, while tensing up his lower body.

“You’re too good at this,” Shining groaned quietly, just loud enough Twilight was able to hear him.

She rewarded him with a chuckle, and quickly relaxed herself as she moved her mouth more downward. As it went down, he felt her tongue swirl about, making sure to cover his aching erection in her spittle, until she stopped as the head of his erection finally hit the back of her throat. He quickly leaned his head back down, and though she wasn’t paying attention to his expression, Shining was amazed at how hot she looked.

Her eyes were closed and though her ragged mane covered lots of her face, he brought his hoof up and brushed it, allowing him to see her expression more clearly. She acknowledged his touch, and opened her eyes, before craning her neck slightly to look up at his face. She didn’t go far and letting her purple eyes lock with his, Shining couldn’t help but smile at her. Even with a cock in her mouth, Twilight smiled as well, until she gave a hard lick, causing his eyes to close once again. The feeling was accompanied by her slowly moving her mouth back up his stallionhood, and he could feel that eager tongue move side to side in a teasing manner.

Once she came to the top, she instantly went back down, before her movements became linear, while her tongue made an effort to lick any area it could. Her hooves quickly matched the pace of her bobs and she went as deep as she could, while she continuously moaned into his erection, no doubt in an effort to please him further. It worked to a great extent and Shining quickly returned the favor by placing his hoof against her mane, and began to gently stroke it, while at the same time he helped guide her along.

Her motions quickly became fluid and with every lick of her tongue and bob of her head, she drove him closer and closer to a finish. He felt it coming; it was a growing intensity he tried to snuff out so hard prior but now he was basking in the sensation and enjoying every twitch, every spasm his cock delivered. He could feel the cool precum flowing out and it reminded him of a leaky pipe ready to burst. He could feel the swelling and the urge to nut so hard starting to take over his mind. Luckily Twilight’s soft moans kept him in check and he knew he would have to warn her of what was to come.

“Twiley, I’m about to cum,” he groaned as he pushed his sister to suck as hard as she could. “When I tap your head, pull your mouth off but keep your hooves moving, okay?”

Twilight mumbled a ‘yes’ in return and quickly changed her movements. She stopped going as deep as she could, but instead, she pulled back and began to eagerly suckle the head of his erection. Her bobs became short and her lips constantly caressed the flaring head of his erection. It felt great, but he tried to stop himself from mindlessly bucking his hips forward from the sensation, but the feeling was short-lived as he felt himself peak.

He waited, drawing out the pleasure as long as he could, until the feeling was too intense to hold back. He grunted as he tensed loins and quickly gave Twilight’s head a tap. Her mouth left with a soft ‘pop’ and Shining heard her take a deep breath before the first wave hit.

He let out another groan as a large spurt erupted from himself and he opened his eyes in time to see the thick line of semen travel in the air before it landed in Twilight's mane. She noticed it as well, but Shining could see a look of bewilderment on her expression as another burst of it followed behind. The second hit his chest, and the rest started to come out in lesser spurts as it all began to dribble on his shaft. Twilight kept her hooves moving, coating his now deflating erection in the white sticky seed until it got so soft that she stopped stroking it altogether.

“What is all of this? It's all slimy and warm,” Twilight asked, as she inspected the semen on her hooves.

“It’s called semen,” Shining panted as he felt the end of his climax greet him, causing a wave of fatigue to rush over his body. “I don’t think there was supposed to be that much.”

His shaft was soaked and the white spunk slowly dribbled down onto his balls, before it all trailed towards the sheets below. He knew a change of sheets and bedding which would be needed later on.

“This isn’t pee is it?” Twilight asked as she brought her hoof to her face and sniffed it. “Why does it smell like watermelon and apples?”

Shining got ready to reply but stopped himself as Twilight stuck out her tongue and licked a bit of it. He opened his mouth to speak but nothing came out as Twilight ran her tongue against her lips, almost in an effort to gauge its taste.

“Even tastes like watermelon and apples,” Twilight replied in an excited tone as she licked more of it. “Did you know it tasted like this?”

“No, I don’t… eat my own jizz,” Shining replied matter-of-factly with a stupid grin on his face. “But that’s not really important. Did you enjoy the experience?”

“Yeah it was fun and exciting to try that,” Twilight told him as she brought her face down to his dying erection and gave it a tantinitive lick. “Can we try it again?”

“I would, but like I said earlier, stallions are usually satisfied after one orgasm,” Shining replied as he looked at his stallionhood and still felt it had some life in it, pushing his mind to go for a second round. “I need a few minutes to get hard again.”

“So we’ll go again?” Twilight asked with eager need in her voice as she wiggled her rump.

Shining looked to her rear and though he was beyond satisfied, he knew she wasn’t.

“How horny are you still?” Shining asked.

“Well… sucking on your penis made me more horny and I would really like you to rub me again,” She said with a smile as she stared with a lusty look in her eyes. “But I kinda wanna know if there is any other way of doing this.”

“What do you mean?” Shining cocked his brow.

“As I was sucking, I couldn’t help but think of how good it would feel to have your penis inside of me.”

Shining tensed up.

“Having it in my mouth was pretty fun and exciting, but I couldn’t help but wonder if you could try to… mount me?”

“Mount you?” Shining asked with hesitation.

“Yeah! Could you?” She asked in return.

“How did you get this idea?” Shining probed further, wondering if she knew more than she was putting out. “You only know what sex is because you watched a pony give a blowjob to another pony. Why would you suggest that I mount you?”

Twilight clammed up and scrunched up her expression.

“I kinda lied when I said I didn’t watch them earlier,” She replied meekly."I watched the whole thing…” her voice trailed off as she bit her lower lip.

Shining said nothing and did find it a bit weird she sucked his dick as good as she did without prior experience, and now he knew why.

“What did they do?” Shining asked.

“When the maid stopped sucking him, he was still hard and pointy, so she turned around and lifted her tail to him.”

Shining noticed Twilight’s back legs fidget.

“And he did a thing where he kissed her back a bunch and slowly mounted her. He ended up sticking his penis inside of her and she cried about how great it felt.”

Shining grew worried as the situation was quickly turning into the problem that he wanted to avoid for so long.

“He rocked his body against hers and I saw him constantly whisper into her ear while he kept nibbling on it.”

“That sounds like they were in love and it wasn’t just a casual sex thing,” Shining muttered under his voice.

“Huh?” Twilight stopped as she looked at him.

“Sorry, I was just thinking out loud. You can continue,” Shining replied as he waved her off.

“Okay… so I watched them until he stopped moving. I’m guessing he orgasmed into her because I didn’t see anything come out of his penis,” Twilight finished as she flashed Shining a smile. “Can we try that next!?”

Shining went quiet as Twilight starred up his face with a big grin on her own. He wondered what to say and his fears of accidentally impregnating her started to play out once again.

“I… rather not,” Shining replied as he looked away, causing Twilight’s ears to droop and her expression to frown.

“Why not?”

Shining scrunched his expression and bit his tongue.

“Are… you worried you’ll make a mess inside of me?” She asked.

Her words rang true in more ways than her young mind could comprehend, but those words were enough for him to figure out an excuse to us.

“Yeah, I don’t want to blow a load inside of you. Semen is a pain to clean and I don’t know how to clean it out from inside of you.”

“Oh… Well, why don’t you try a spell of some kind?” Twilight suggested, almost like a lightbulb went off in her head.

“What kind of spell?” Shining asked, wondering what she was thinking.

“If you’re scared of making a mess inside of me, why don’t you put up a barrier of some kind? You know, to catch it all or something.”

“Huh?” Shining replied as he tilted his head. “I don’t think it can work like that. Plus if I put a barrier spell up inside of you, then I doubt you’ll enjoy it.”

“Why not?

Shining opened his mouth to reply but stopped as a new idea played out. At first he thought her idea was stupid and that it didn’t work, but a quick reminder of how the ponies anatomy looked, he wondered if a barrier spell would actually work.

Specifically put, he wondered if he was able to place a barrier spell just outside the entrance to her womb to avoid his worst fears.

“Actually, I think your barrier spell idea may work,” Shining told her as he looked up to the ceiling. “I just need to tweak it slightly.”

Twilight smiled at him while giddly bouncing on the bed, before she quickly looked back to his penis.

“Looks like you’re already getting hard again as well.”

Shining broke his thoughts and looked down, quickly noticing that his cum soaked stallionhood was slowly coming back to life. He was still horny, he wouldn’t deny that, and the thought of being able to stick it in his little sister was very off putting, but he wasn’t going to ignore the intense spike in arousal as he thought about mounting her without the worries of knocking her up. His loins twitched and his erection started to slowly point back upward until he knew it was time.

“Yeah, I am,” Shining snarked as he lit up his horn and looked to Twilight. “I need you to turn around for a second.”

“Trying a spell?”

“Yeah. I got something in mind. Need to slowly work my magic in.”

Shining lit up his horn as Twilight lifted her body off the covers and turned herself around for him. His eyes latched onto her fillyhood and Twilight swished her tail at him, eagerly showing she was waiting for him. Keeping his eyes on it, Shining cast a spell and a small mass of magic appeared in mid air. It was about the width and diameter of a bit, and noticing it was floating towards her rear, Twilight spread her legs a bit more and lit up her horn as well. Her spell was much the same, but instead she brought to the side of her slit and pulled it. She didn’t moan but Shining watched her tremble as she split the spell, allowing her to move the other side as well. Now fully spread, Shining couldn’t help but smirk as another pulse went through his erection.

“I’m going deep, so you may feel a pinch at some point. If it hurts too much, tell me to pull out, okay?” He asked her as the mass of magic hovered just outside her wetness.

“Okay. I’m ready.”

Shining pushed it in and Twilight stifled a moan as the mass of magic disappeared inside of her. He closed his eyes, allowing him to concentrate and feel with the magic, almost like it was an extension of himself. He felt everything with his mind; the hot and tight walls around the magic tightly squeezing it as it pushed further and further in, until he hit the entrance of her womb.

“Ahh,” Twilight cried softly, halting her own spell, which caused Shining to open one eye.

“Did I hurt you?” Shining asked.

“No, you just touched something that felt weird,” she replied.

“Then my magic is where it needs to be.” Shining closed his eyes again.

Twilight said nothing but as Shining’s magic was able to map out the small opening. He tweaked the spell and turned the mass of magic into a wall-like barrier that completely covered the entrance.

“It’s about to pinch, so brace yourself, Sis,” Shining warned.

Twilight ‘mhm’d’ at him in response and he pressed the barrier against her. A small groan left her mouth but nothing more as Shining relaxed his mind and opened his eyes. Even with him relaxed, Shining knew the spell would constantly need to be focused on. His horn stayed lit and Shining hoped the spell and his mental fortitude would be strong enough to endure the intense feeling to come.

“Can you feel anything inside of you?” he asked.

“I felt it for a second,” Twilight started as she swayed her hips. “But I don’t feel anything now.”

“Alright,” Shining spoke with a deep sigh as he began to pull his body up and stood on all fours. “Are you really sure you want me to put this in you?”

Shining pointed to his hardening erection and Twilight stared back at it with almost hungry eyes. She smiled at him and braced her legs against bed, before her horn flared up once again. He watched her magic return to her fillyhood, once again spreading the outer lips for his pleasure.

“Give it to me, Shiny,” she purred at him.

“Alright, I guess we are actually doing this,” Shining said with a smirk as he moved to the edge of the bed and hopped off. "Come with me."

Twilight followed and both stood on the floor.

"Hey sis, I need you to turn around and place your front hooves on the bed," he told her.

Twilight did as asked and turned her rear back to him, before propping her hooves on the bed. Once set, she leaned forward and rested her chest against it, before her head quickly followed.

"Like this?" she asked as she looked over her shoulders and fidgeted her back legs, so she could spread them open.

"Almost," He quickly stood up on his hindlegs and though his balance was wobbly, he placed his front hooves against her flank. "I'll guide you the rest of the way."

He stepped forward, which caused Twilight to shift as well. He continued to move and eventually her hind legs hit the side of the bed. With her upper body on the bed, he took another step, causing her back hooves to rise into the air, almost letting her back side dangle. Thankfully the bed was high enough that he was able to line up his stallionhood, and moving forward one last time, he rested the tip of his erection against her fillyhood and stopped, before he looked down.

"You cozy?"

Twilight took a deep breath.

"Yeah, I'm fine."

“I don’t know if this will hurt you or not,” Shining spoke. “Just tell me to pull it out if it does.”

“Stop worrying so much and put it in me,” Twilight begged as she looked over her shoulders.

"I would, but you're a virgin, so I'm scared I'll hurt you."

"What's a virgin and why would it hurt?" She asked.

"A virgin is a pony who hasn't had sex before, and unlike me, a mare's first time is a bit different."

"Really? How?"

"If I put my penis in you, I'll end up breaking your hymen. As far as I know, a female's first penetration is supposed to be painful."

“Oh…” Twilight’s ears drooped and she looked away, before she went quiet for a few seconds. “Wait, what’s a hymen?”

“It’s basically a small bit of flesh that tears when you get sexually stuffed with a penis,” Shining told her, doing his best to put the basic definition of it into words.”It’s a one-time thing thankfully, and most ponies dub it ‘popping your cherry’.”

Twilight continued to look away, almost like she was having doubts.

“I’ll be as gentle as I can be, but I just wanted you to know what may happen,” Shining told her as she looked back at him.

“Ok, I trust you,” She replied with confidence as she swished her tail, allowing it to brush against his stomach. “If it hurts too much, I’ll stop you.”

“Alright. Let’s do this.” Shining just smiled as he brought a hoof to his erection and held it in place, getting him ready to insert it in. He lined it up perfectly and as the tip pressed more against the tight wetness, he couldn’t help but jerk his hips forward.

Both ponies tensed up, and Twilight let off a loud, surprised moan as the large head slid in. Shining groaned and his eyes went wide as the hot and very tight opening clenched tightly around the head of his erection.

“Oh gosh, that feels different,” Shining mumbled as he found himself completely still. "That's very tight as well."

“Mhmmm, that feels great,” Twilight cooed at him. “Put more of it in!”

He was hesitant, but quickly did as he was asked and stuffed another inch in.

Twilight moaned again but Shining quickly detected a hint of distress in her voice as well.

“You okay?” He asked.

“I felt a pinch,” she replied. “I think you popped it."

Shining started to pull out.

“No no, don’t take it out,” Twilight spoke out, which caused him to stop. “I can handle it.”

“Are you sure?”

“Very, but be gentle with me.”

“Okay.” Shining slowly pushed his erection back in.

There was a bit of resistance as he pushed in, no doubt thanks to her smaller size, yet Shining was able to slip himself in with relative ease. Even with her wet and accepting of his erection, Twilight tensed up and continued to groan as more of it went in. It was a vice-like grip that continuously applied pressure, but it eventually eased up as Twilight's body relaxed and grew accustomed to it. The further it went in, the more comfortable they both got.

Once almost half of it was in, Shining leaned forward and rested his underbelly against her back. Her body heaved slightly as he pressed against her, and he heard her take a deep breath in.

"Can you breathe easy?" He asked as he steadied himself.

"Yeah I'm fine," she answered, before she wiggled her rump, allowing his stallionhood to poke around.

"Good. How does it feel inside of you?" He probed further, before he closed his eyes.

"It feels big inside of me, but it doesn't hurt as much as I thought it would. I'd feel better if you would rut me though," she noted as she leaned up and rubbed her mane against his chest, making sure to not poke him with her horn in the process.

Shining felt at ease with her words, but knew he had to be careful. Slowly pulling his hips back, Twilight moaned as his cock started to exit her pussy, until only the tip of it remained inside of her. He slid it back in, but never further than his medial ring. He was scared his dick would bump against the barrier inside, which would cause his mind to falter and his spell to break, if hit hard enough. That realization almost came true as he accidentally pushed his ring in, and he felt the tip of his stallionhood press against the barrier. His spell didn't drop, and Twilight showed no reaction, but Shining knew he found his limit with how far he could go in. Just under half of his dick would enjoy that tight and very warm crevice, and though he wished he could bottom out inside of her, he had to put that fantasy in the back of his mind.

He pulled out and once again he kept only the head nestled in, until he gave his hips a hard buck. A gasp left Twilight's mouth, but it was cut short as he pulled back and repeated the motion. He was quick to find his rhythm, and his thrusts were short but fast enough that he provided vast amounts of pleasure to Twilight. Shining could tell she was enjoying it as well. Her moans were soft and every time he pushed it forward, they steadily increased in volume and it drove him further and further.

He kept his pace, never deriving from it, but found himself starting to moan from how great it felt. The constant clenching of her walls against his dick made him wish he could enjoy that sensation forever. It made him want to rut her faster and give in to his animalistic nature more than anything. His mind gave in for a moment and he gave her a hard thrust, causing a carnal and needy gasp escaped her throat. He hit the barrier and the feeling of it quickly brought him back to his senses. He gave his head a hard shake and looked down at the bed.

Part of Twilight’s face was showing and her tongue was hanging out while she stared forward at the wall with almost a glazed over look in her eyes. Her continuous gasps and pants showed there was nothing but pure enjoyment in her body. He loved the look more than anything and it made his arousal spike and it quickly became a game of who would outlast the over first.

It didn’t take long though, as Twilight’s moans picked up and Shining found her body trying to rock against his. The constant bucking of her own hips caused the barrier inside of her to get hit with the tip of his erection. The feeling was maddening and he was sure his spell would fall if she kept up her motions.

“Please give all of it to me!” she moaned wildly at him.

Shining grumbled, wishing he could give her all of it. Instead he steadied his back legs and raised his upper body up. His hips never stopped and now at a standing position, Shining placed his front hooves against her shoulder blades and pushed her gently into the bed. He put more power and speed into his thrusts, while making sure it never went too deep. She didn’t seem to mind the feeling of being pushed into the bed; instead he found her moaning and panting even harder as his erection poked deeper into her clenching walls.

Suddenly, a loud moan played out, very reminiscent of a cry mixed in with a moan of utter satisfaction, and Shining felt her clench harder than ever before. Her head jerked upward and she stared mindlessly at the wall ahead of her. He gritted his teeth and pushed harder against the intense feeling, and quickly realized that she orgasmed for a third time. He felt the convulsions and her moan turned into a soft squeak as she bucked her hips against his plowing erection. He never slowed and made sure he gave her a finish that was worth all of the effort.

“Please don’t stop,” she spoke quietly as she leaned her head back into the bed. “Please don't ever stop!”

His gritted expression turned into a proudful smile and he felt her body start to relax once again. Her body trembled weakly, and her walls still clenched, but he found it not as tightly as before; yet the feeling was short-lived as he felt a familiar sensation starting to build up once again in his own loins. He took a sharp breath in and exhaled it through his nose, before his eyes went to her back. He saw her tail flickering wildly, and he quickly brought back one hoof, and wrapped the end of her tail around it. He gave her tail a tug and she moaned at the feeling of it as she looked over her shoulder and stared into his eyes. Shining gave his sister a smirk as he quickly started to feel himself nearing the point of no return.

He let out a grunt, and a growl quickly surfaced behind it. It sounded feral and almost unnatural to Shining, but he ignored it and pushed harder and faster. More of him slipped into her as he plowed and neared and once again, this tip of his erection started to beat against the barrier. It didn’t stop him, nor did it slow his pace. He was close, too close to care and without realizing it, he felt his horn starting to tingle. Unsure of the feeling at first, Shining quickly realized he was losing his focus on the spell. He felt it cutting out and every time he hit the barrier, he felt his mind falter. Quickly pouring more magic into it, he tensed up, but was too far deep into his motions that stopping wasn’t an option for him. He plowed, he tensed, and eventually he felt that orgasmic click inside of his body. Five seconds, if not less, till he came.

Twilight let out a loud cry of pleasure and it pushed him over the limit. He felt the swelling begin to build and he felt the need to go as deep as he could go. Another feral grunt came out and Shining gritted his teeth and closed his eyes. The feeling was so intense that he felt his spell faltering more and more and in a last bit of effort, he poured more magic into his spell.

Then he came… and he felt a sharp pain in his horn as the spell broke. He winced and cursed under his breath while his erection gushed out whatever semen he had left in him. He quickly pulled out, but knew it was too late as two weak surges pulsed through him before he could. His erection left his sister's ravaged orifice with a loud and wet shlick, which caused a soft groan to leave Twilight's mouth. He looked down at his cum soaked erection, noticing a bit of red on it, and though it was off putting, Shining was more worried when he didn't notice any spunk immediately flow out of her gaping pussy.

"Are you… done already?" Twilight asked as she panted at him, almost like she was surprised he wasn't still going.

Shining said nothing and stared with a horrified look on his face as a bit of semen started to finally flow out of her.

"Shining? Are you okay?"

"I'm fine," Shining lied, breathlessly. "I'm finished sadly. Do you feel better at least?"

"I… feel a lot better actually," Twilight replied as she moved her back legs. "It's not hot and itchy back there anymore. It just feels very wet and cold now."

"Good to know." Shining breathed a sigh of relief, but it was momentary as Twilight pulled her tired body onto the bed.

Shining moved his hooves away from her shoulders and looked down as a bit more of his semen spilled out.

"Don't get too cozy, sis," Shining continued.

"Why? Can't I lay down for a bit?" Twilight asked as she relaxed her body against the bed.

"I gotta change the bed sheets and we got to clean ourselves up," Shining told her, hoping a hot shower and a quick cleaning of her privates would be enough to save him. "Let's go have a shower and I'll help you clean up. You wanna go warm up the water while I strip the bed?"

"Okay," Twilight replied as she pulled her body up and hopped off the bed. She walked to him and stood by his side

Shining noticed a content smile on her face as he lowered his upper body and stood on all fours. As he touched the floor, Twilight quickly leaned in and gave him a kiss on the cheek.

"Thanks for helping me, big brother," she spoke in an affectionate tone as she whispered into his ear.

"Anything for you, sis," he replied with a weak smile, before Twilight walked away and exited the room.

Now left to his own devices, Shining just stared blankly at the bed before him. His mind took note of the multiple wet spots, but it did nothing to alleviate the intense feeling of dread that was starting to cloud his mind.

Everything he had done, every precaution he tried to do; it all amounted to nothing in the end. Sure he managed to sate her intolerable heat cycle, yet it came at the cost of everything. His sister's virginity, her once innocent demeanor, and most importantly, her future. He felt defeated and pathetic at his lack of control, constantly wishing he wasn't so careless in the crucial moments near the end.

More thoughts raced through his head. Images of his parents scolding him and disowning him for what he just did. He pictured them casting him out to the streets, wishing never to see or hear from him ever again. The images got worse as he pictured Celestia staring him down with ill and murderous intent for impregnating her star pupil. Would she banish him from Equestria for his horrid act? Or maybe even banish him to the moon or the sun instead? He shook his head and did his best to silence those horrid thoughts in an effort to not fall into despair.

Shining sulked his tired body into the side of the bed, before his head fell down and landed on the crinkled sheets. He sighed deeply and attempted to light his horn up, but failed to even ignite a magical spark of any kind. A tinge of pain quickly followed, but Shining just groaned and rolled his face into the sheets.

"How in Tartarus' name am I going to explain this mess?"

Two Days Later

View Online

Shining walked the dimly lit halls with an unsteady pace and a guilty conscience weighing on his mind. Time itself seemed to slow to a crawl and during the last few days all he could do was constantly worry about Twilight. Her cycle was gone and she was able to function properly, but with her no longer in heat, Shining knew she was pregnant. He knew very well how a mare's body worked.

He constantly asked her for the last few days if she was feeling okay and though she was content and happy, Shining couldn’t have been more horrified when she told him the hot and itchy feeling was gone completely. He wanted to ignore it and even tried to convince himself otherwise that her body was just acting abnormally and she would resume her natural cycle as the days went on. The illusion in his mind worked for two days but Shining started to slowly accept what he did. His pace quickened as he focused on the destination in mind. The house library, but not for spells; he needed to talk to his father.

He couldn’t keep this ordeal a secret and he knew it was just under a week until the natural cycle for all mares and blossoming fillies would be in effect. Since Twilight couldn’t experience it, his parents would catch on very quickly and things would snowball out of his control.

He came to the library and though his guilty conscience weighed even harder on him as his father came into view, Shining knew he had to remain steadfast in his resolve. As he walked in, he noticed his father laying on the bean bag cushion, casually reading a book without a care in the world. His father didn’t notice him at first, but as he walked closer, he saw his father’s ears perk up and his attention quickly turned to him.

“Ahh, hello son,” Night Light said in a warm and comforting tone. “Looking to do a bit of reading to wind down the evening?”

“Not exactly.” Shining took a deep breath. “I need to… talk to you about something serious.”

“Really now? Is about why you’ve been distant the last few days with me and your mother?” Night asked, quickly reminding Shining that he had been too ashamed and embarrassed to show his face, much less even talk to them.

“Yeah. I… I had to do a lot of thinking,” Shining let out a sigh as his eyes darted around the room in a vain effort to distract himself as he spoke.

“Nice to see you’re opening up,” Night replied as he closed the book and floated it to the ground. “Your mother and I were worried we did something wrong.”

“Don’t worry, it wasn’t you guys…” Shining’s voice trailed off sheepishly as he sat his haunches to the ground and rubbed his front hooves together nervously. “It-it was me.”

“What did you do?” Night asked softly.

“I… I… I…” Shining couldn’t speak as the words got stuck in his mind. He knew what to say, he had practiced the potential conversation out in his head all day, but actually coming forth and saying it wasn’t going to be as easy as he thought. How could he come clean about what he did?

“This sounds like something serious,” Night said quietly, as his carefree expression turned into a stern frown and his voice took a more commanding tone. “Shining, what did you do?”

Shining tried to speak again, but the words refused to leave his mouth. A loud sigh was all he was able to muster and it transitioned into a groan of shame as he felt the soul piercing gaze of his father. He tried to look at his father’s face, but he couldn’t bear it. He instead looked at the ground and it felt like the weight of the world was crushing his soul into nothing, to the point he felt like he would start crying at any moment.

A hoof touched his shoulder and Shining tensed instantly at the feeling. The touch was surprisingly gentle, and before he could react, his father slowly trailed his hoof to Shining's chin and tilted it upward, allowing both stallions to stare at each other. Shining found a bit of nerve and looked into his father’s eyes, still nervous and anxious. As they locked Shining felt the tension in his body and mind ease up as he could read a bunch of emotions before him. Worry, warmth, affection, and concern. He could see it all, he wasn’t sure why, but the longer he stared, the more at ease he started to feel.

"It's okay, you can tell me."

“Ok.” Shining took a deep breath, and steadied himself, doing his best to muster up the rest of his nerve. “Dad I… Twilight was in heat two days ago.”

The words spilled out finally, faster than he could mentally keep track off. As they left, he instantly regretted his words, and tensed back up with worry as he awaited his father’s reaction.

“Really now? So… Twilight was in heat the day me and your mother were at the summit,” Night replied, his tone shifting to one of a parent ready to scold his child. “And judging from your behavior… I am going to safely assume you did the one thing I told you to not do if Twilight or even your mother, fell into a heat cycle?”

Night removed his hoof from Shining’s chin and the younger stallion looked back at the floor with utter shame.

“I-I tried to be safe about it…” Shining spoke meekly as he felt a whirlwind of emotions building up. “I-I really didn't mean to…”

“Shining.”

Shining tensed up even more as his father’s tone shifted back to a very commanding and unapologetic one. He dared to not look up at his father’s face anymore, knowing full well what awaited him.

“I’m sor-”

“Shining.”

“Dad. I’m really sorry.”

“Shining, look at me,” Night lifted his hoof.

Shining saw the hoof at the corner of his eyes and shut them out of fear of getting hit by it. He winced and brought up a hoof to shield himself, ready for whatever punishment was about to be dished out. Seconds passed and nothing came. Shining kept his eyes closed, but wondered why his father wasn’t yelling or striking him. He knew by default he deserved the former, and then some, but with nothing happening, Shining opened up.

He expected his father to be seething as dilated pupils stared him down with ill-intent and unbridled rage… but it was far from it. His father’s expression was emotionless and Shining couldn’t get a read on him. Shining looked on quietly and did his best to maintain eye contact with him, until his father closed his eyes and breathed in an excessive amount of air.

“Soooo.” Night sighed deeply, his voice almost sounding like it was trembling. “I have questions; several of them, however the biggest question comes first and I want an honest answer: Did you rape your sister?"

Shining's eyes widened as he jerked his head back. He was expecting many questions starting with ones like 'do you realize what you've done?' Or 'what's wrong with you?'.

"What? No, I could never hurt Twilight like that," Shining replied as his nerve returned to him and he looked his father in the eyes with an unhindered look.

Shining stopped talking and both ponies quietly stared at one another for a few seconds, whilst never breaking eye contact.

"Alright, I believe you… for now," Night said at last. "Next question: You're a smart stallion, and you know the risks of pregnancy, so why didn't you pull out?"

Shining's eyes unfocused and he blinked several times as the realization settled in his mind. It was so simple, yet it never occurred to him during the act to pull out and spray his climax into the bed sheets. He was too lost in the sensation that rational thought had been thrown out the window at some point.

"I-I didn't think about it at the time," Shining stammered out as his head went down in shame and he once again stared at the floor. "I was… I knew the risks and tried to put that into effect. I tried to explain that to Twilight as well but… we ended up trying a barrier spell instead."

"Barrier spell?" Night probed.

"Yeah, I thought if I could cover the entrance to her womb, we could prevent it."

"Magic and sex don't mix well for the inexperienced." Night let out a deep sigh of disappointment as he brought a hoof up and rubbed it against his forehead. "Did your magic short out?"

"Yes. It happened right at the end and before I could react fast enough…" Shining's voice trailed off as his body and mind felt weak, before he rested his front legs against the floor to relax himself. "I'm sorry Dad. I know you're mad at me and nothing will change what I did."

There were a few moments of silence as Shining grovelled at his father's hooves. His father showed no reaction to him, and it only made Shining worry more and more.

"I'll be honest; I'm mad, but I'm more disappointed than anything," Night said finally.

Shining's ears sulked down and he let out a defeated groan. Hearing his father was more disappointed than mad should have made him feel better, expect it did the opposite.

"I'm sorry," Shining said meekly as he looked up.

This time Shining could see emotion finally. His father looked distant and distracted while his eyes were very much present with sadness and regret. Seeing all of it made Shining feel like garbage, knowing he was causing unspoken distress to his father.

"Sorry won't fix this mess, Son." Night laid his body down and was head level with Shining. "Though I am upset and very disappointed at your lack of self control, I'll say this; I'm happy you brought this up when you did."

"You are?" Shining asked, confused by the hint of praise in his words.

"Yeah. It takes a grown stallion to admit his wrong doings," Night started as his lips turned into a soft smile. "Considering how big this is, I'm glad you came clean before me and your mother found out the hard way." Night's smile faded and his expression went back to his neutral look. "That being said, now that I heard it from your point of view, I'm going to hear it from Twilight's perspective as well as the full truth."

"Full truth?" Shining cocked his brow and grew confused by his father's wording.

"Shining, how well do you know our nation's history?" Night asked as he stood up and focused his eyes on the bookshelves around them.

"I know the basics about how Equestria was founded," Shining pulled himself up. "But what does that have to do with anything?"

"I'm getting to that," Night replied as his eyes scanned the books more closely. "Naturally during the early days of settling, there was conflict with other races and constant territorial disputes that almost always led to fighting. Thanks to constant strife, spells were created for… well let's just say ponies nowadays wouldn't be open to the ethics behind them."

"What kind of spells?" Shining asked as he trotted to his father's side.

"Borderline dark magic," Night replied sharply as he partially pulled out books, before returning them back to their rightful place. "Stuff like mind control, necromancy, and lots of other spells that could punish an enemy both physically, mentally, and even emotionally."

Shining stayed quiet, not looking forward to what the conversation was leading to.

"As ponies settled, the use of such spells became less and less needed to the point that Celestia outright banned and forbid the use of them," Night continued as he pulled another book and Shining quickly noticed it was radiating a green magic shield, very reminiscent of a ward spell. "Ah, here it is. Anyhow, certain spells became lost to time, while others were deemed a 'necessary evil' and were kept around."

Shining watched his father put the book to the floor and conjured up a small magical key, before he laid it flat against the book itself.

"Considering I'm Captain of the Royal Guard, I have privileged knowledge about these spells, along with access to a select few." The spell faded around the book and Shining watched his father open it up. "Now to the point; I'm going to use one of these spells on you." Night quickly flipped through the pages until he stopped.

"Which one?" Shining asked with worry in his voice.

"A spell that lets me read your memories while you sleep," Night replied. "It was a spell created by Princess Luna, and used mostly by the elites among the troops."

"Princess Luna?" Shining asked, unaware of who she was.

"You'll learn about our 'Banished Princess' in your final year at school, but that's a conversation for another time. Back to the point; this spell was created in an effort to expunge brutal interrogation tactics in place for a more civil approach. As you sleep, I would be able to read your memories like a book and would see everything and hear everything from your perspective. Think of it as watching real life from the past, but you couldn't interact or change anything."

"So it's a mind reading spell. That… sounds scary," Shining replied, realizing the full power of a spell like that could easily shift the balance in fights and potential strategies.

"That's putting it mild honestly. Only the princess and high military officials like me have knowledge and access to it." Night finished reading the book and slammed it shut. "You will not tell anyone about this conversation or the fact I'm using this magic for personal interest. Do you understand Shining Armor?"

Shining took a moment to take in everything he learned. The fact that his father told him such privileged knowledge shows that he still trusted him, but he realized it would be another burden to carry.

"Yes sir," Shining replied dutifully.

"Good. Just so you know, I'll be using this spell later on Twilight as well… expect she'll already be sleeping and won't know about the specific of this. Now after hearing this brief history lesson, I'll ask you again; did you rape your sister?"

"No sir, I could never bring myself to do such a thing," Shining replied without hesitation.

"Great." Night flared his horn up. "I better not see otherwise, because if I do… well, let's just say the Princess has no qualms about putting colts in Tartarus."

Shining tensed and swallowed back a large lump of anxiety in his throat. He knew how Tartarus was a prison that housed Equestria's worst offenders along with many different creatures. Hearing that he could end up in that place at a young age wasn't something fond to think of.

"I'm not lying to you father; you can read my memories and see for yourself," Shining told him proudly.

"Excellent… now shall we begin?" Night asked.

"Wait? Right now?" Shining asked in return.

"Of course. The sooner I see your memories, the better. You didn't have plans for the evening right?"

"Other than some homework… I got nothing else," Shining shrugged his shoulders.

"Perfect." Night flashed a smile. "Now close your eyes and relax. You'll feel this almost instantly so lay down."

Shining nodded and did as instructed. The second he closed his eyes, he felt the tip of his father's horn touch his. For a brief second there was an odd numbing sensation, before his body gave out and his mind went blank.

Tick… tick… tick…

The waiting room was deathly quiet, save that familiar and ominous ticking. From his seated position, Shining said nothing as he stared at the white ceramic floor tiles below him, almost able to make out his own troubled reflection in it. At his side sat his father, but unlike Shining, Night was sitting upward and starting quietly ahead, eyeballing the rest of the hospital lobby, while he focused on the hallway where Twilight had been led off into. Shining didn't dare look up at him, thanks to the tense situation they were in. Two weeks had passed and it was finally time to truly confirm if Twilight was pregnant.

Ever since that day where his father had read his memories, Shining found both parents distracted and very distant from him. While his mother was always upfront about how she felt with him, his father kept his thoughts to himself. Shining feared speaking with him, wishing not to incur his father's wrath in the manner. He could never read his father's expressions or emotions well, a trait that only a hardened military captain possessed. One wrong question, he feared, would set off his father.

"So."

Shining nearly jumped out of his skin as he heard his father speak.

"Mhm?" Shining replied meekly.

"So here we are," Night said with a deep sigh as he leaned back in the chair. "I sure hope you are ready for the outcome of the test, son."

His words were cold, but Shining detected no ill will or seething anger in them as he gingerly swung his hanging hooves back and forth.

"I'm sorry I caused this mess," Shining spoke, a very familiar phrase he had been conveying to his parents over the past weeks.

"Stop apologizing. I've heard enough apologies to last a lifetime from you already," Night replied scornfully. "Not enough magic at my disposal to change the past anyway. All that remains is the fallout and consequences of your actions you've got to live with."

Shining said nothing and continued to stare at the floor.

"I'm done being disappointed at you anyway," Night sighed deeply as Shining felt a hoof touch his shoulder. "Now I'm just mad at myself."

Shining cocked his brow and looked to his father's lap.

"Why?"

"I spent a lot of time looking at you and your sister's memories and even more time thinking about what I saw," Night replied as Shining started to slowly pull his body up. "Lots of things stuck out to me, most of it was things you could have done differently. You could have ignored your sister like I always told you too. You could have continued to search for the spell, but instead you didn't."

"I-I stopped bec-"

"You stopped because you made your sister cry," Night cut in. "Your mother always told you to never make your sister cry, and if you did, you fix the issues before they become animosity and hatred."

Night sighed again and pulled Shining's body close to his.

"You're a good stallion, Shining," Night told him as Shining looked up to his father's face and saw a look of sorrow and regret. "I just wish your heart wasn't bigger than your brain."

"I'm sorry," Shining replied.

"I told you to stop apologizing." Night turned his head and looked down at Shining. "Another thing stuck out to me was that you tried to look for a certain spell that suppressed a heat cycle. Sadly it wouldn't have mattered anyway if you found it."

"Really? Why?"

"That spell you were looking for was in a book detailing expert level alteration spells. We actually don't have the book in the house so your search would have turned up empty. Sadly it didn't matter if we had it or not. You're only apprentice level, so you wouldn't be able to tackle a spell two grades above your range."

"Oh." Shining sulked back down, feeling low and defeated for his lacking ability.

"Don't sulk," Night ordered as he placed a hoof against Shining's chin and started to guide his head up. "Even Twilight wouldn't have been able to perform the spell, so in the end it wouldn't have mattered."

"Twi couldn't do it?" Shining asked as he looked back to his father's face.

"Yeah. Twilight's got talent. Celestia said so herself; yet it's raw talent that needs to be refined and polished. She's only recently started tackling adept level spells with Celestia, and that alteration spell was more intricate than most expert spells were."

Shining quietly processed the information and stayed silent.

"That being said, that's the reason I'm mad at myself." Night moved his hoof away and stared forward. "I should have foresaw this kind of thing happening, and yet it never clicked in my mind that Twilight would be a mare that would ever experience an early cycle. I was careless and I could have prepared emergency scrolls for you to use… but dwelling on it won't change it now. Now… we just got to be ready to raise another foal."

"We?" Shining asked, curiously.

"Of course." Night looked to Shining with a skeptical look on his face. "You two aren't raising that foal alone, not while you're still going to school; however you better be ready for big life changes and lots of sleepless nights. Trust me, I went through it twice. At least I can prep you for what's coming."

"What's coming?" Shining asked.

Night stayed quiet for a moment before a smirk and a small laugh followed.

"Pickles, donuts, ice cream, and pineapple pizza," Night chuckled before he recovered his stern demeanor. "Lots of late night cravings… especially after the five month mark."

Shining stayed quiet.

"There's also going to be lots of mood swings and unstable hormones, even more so considering how young Twilight is," Night continued. "Your patience is going to be tested, but even with that being said, Twilight will be looking to you for comfort and reassurance, so you're going to have to be a supportive pillar for her. It's a lot of trial and error, and no amount of books will give you all the answers to being a parent… but you'll figure it out. Parenting comes naturally; you just gotta be willing to adapt. Me and your mother will guide you along as well, so you don't have to ever worry you'll be doing this alone."

Shining quietly let the words sink in.

"One more thing; now that you're go…" Night's voice trailed off as he looked up. "Ahh, here comes Twilight and your mother."

Shining tensed and starred in the same direction and quickly noticed the both of them walking towards them. Their expressions were somber and Twilight looked like she was distorted and lost in her own thoughts, while their mother wasn't looking too impressed at all. Her expression was neutral for the most part but as they're eyes met, Shining felt resentment targeted at him.

It didn't surprise him. After learning Twilight was pregnant, his mother was very vocal with her displeasure. Within the first week, she would constantly berate him for his actions. Shining never protested when she started to go off on a tangent, and he just sat in place to take it all in, knowing he deserved all of it. She stopped eventually, thanks to his father talking to her, but she still distanced herself from him, and focused more on comforting Twilight.

"Sooo… what's the verdict?" Night directed his question to their mother, Twilight Velvet.

"Hmph," Velvet groaned with disdain as she looked to Shining and shook her head at him with disbelief. "Well… she's pregnant. She's very pregnant."

Shining sank more into his seat.

"What do you mean by very?" Night cocked his brow.

"Let's just say our work will be cut out for us," Velvet told Night before she looked back to Shining and took a deep breath. "The doctor noticed there was more than one foal developing."

"What?" both father and son said in unison.

"She's expecting twins," Velvet replied, almost like she didn't believe the words herself. "You got your fourteen year old sister pregnant with twins, Shining Armor."

Two Years Later

“Daawa.”

Shining’s eyes jolted open as a very familiar sound filled his ears. He stared forward, blinking and clenching his eyes open and shut until the blurriness in his eyes ceased to exist. Once everything came into focus and he became more aware, he found his stiffened neck awkwardly resting his hoof in an upright position, while a bit of drool hung from his lip.

“Good girl, you woke daddy back up,” a chirpier and very enthusiastic Twilight spoke up.

Still trying to get rid of the cobwebs, Shining shook his head repeatedly, until he was able to focus on the three unicorns before him; two of which were his colt Starry Night and his filly Twinkle Shine. Both sat upright in their high chairs, staring at him with wide and curious eyes, before he turned his attention to Twilight.

“Sorry, didn’t mean to fall back asleep,” Shining groaned as he spoke.

“It’s okay, Shiny. It was a long night for the both of us,” Twilight replied.

His sister looked as bad as he felt. Her disheveled and bedraggled mane flopped to one side, while her half-lidded eyes stared into his. Despite her messy and overly tired look, she had a big smile plastered across her face as she held a jar of baby food with her magic.

“Open up Twinkle, here comes the shooting star!” she chimed as she lifted a spoon full of greenish goop. “Say aaaahhhh…”

“Aaaaamphm,” the baby replied as it leaned forward and opened its mouth, taking the spoonful in. Shining couldn’t help but chuckle as his baby swallowed the food and scrunched up her expression for a brief second, before she opened her mouth up for more.

“Ah ahhhh.” Twilight shook her head. “It’s Starry’s turn.”

His second baby immediately let out a loud scream of excitement as his little hooves pounded against the hard plastic surface on its chair.

“Oooohhh, somepony’s excited this morning,” Twilight mused as she reloaded the spoon and floated it to him. “Here comes the shooting star!”

As Shining watched on, he curiously watched the scene play out as he started to reminisce. He found it hard to believe that two years had already passed. What was once grueling, endless months of supporting his sister through her pregnancy, quickly became days that never seemed to last long enough. It was challenging, and though there were days where he felt like he was at his limit, he pressed through it and stayed strong for both his and Twilight’s sake.

When it came time for the twins birth, all that effort came to a boiling point. Months of love and care teetered on the edge as he paced endlessly back and forth in the hospital, while his father stayed calm and collected, constantly reassuring him everything would be fine, despite complications. He heard and listened, but it never stopped him from worrying regardless. For better or for worse, his parental instincts had long since kicked in, and he could never forget the sheer amount of stress and anxiety he felt that day. As bad as it was, it all melted away when Shining was able to hold his newborn foals for the first time.

Despite the ups and downs of parenthood, both Shining and Twilight found that parenting really did come naturally to them. Sure some things took longer than other things to get the hang of, as well as the constant shifts in sleep, both found their stride. As time rolled by, parenting quickly became second nature to them.

"Shining."

Shining's ears perked up as the voice of his mother came from behind. Swiveling around on his stool, he noticed his mother busily cleaning and preparing baby bottles at the sink.

"Yes, Mom?"

"Before you leave for work, can you make sure to grab your father's lunch? He forgot it again." She replied with a motherly tone.

"Sure thing, Mom." He needed to report to him for his shift anyway. Shining hopped to the floor, noticing the clock at the corner of his vision. "I got a few minutes to spare. Would you like a hoof with the bottles?"

"I'm fine dear, thanks for asking." Velvet turned to face him as a faint smile appeared on her face.

Shining smiled back and turned towards the table, just in time to dodge a magically wrapped ball of baby food being thrown at him. He ducked and the floor landed somewhere behind him, before he pulled himself back up and stared at the colt responsible. At his back he heard his mother sigh and no doubt quickly wiped up the small mess. Focusing on Starry's stubby horn, Shining noticed it was wrapped in a dark blue aura of magic. A slight smirk appeared on Shining's face as his son's cheerful and innocent expression heavily outweighed Twilight's nervous one.

"Sorry Shiny. I thought I cast the forbearance spell on him." Twilight cringed and forced a smile.

"It's fine, Twiley. It's actually more refreshing to see him using magic anyway," Shining replied as he lit up his own horn, mentally noting the small difference in horn size between his foals at the same time.

As Shining cast a spell on his son, the magic around Starry's horn faded, and the baby looked upward, almost like he was puzzled by it. Once the spell was complete, Shining walked around the table and came close to his foals.

"You two be good for mama and nana while daddy's at work today," Shining said to the both of them as he gave both a kiss on the cheek.

Both foals cooed and giggled as they lifted their front hooves and pointed them out at Shining, a signal that they wanted a hug. Shining silently obliged and lowered his head towards Starry and then Twinkle, letting each of them hug his face.

"Give daddy a boop on the snoot," Twilight chimed as Shining pulled away from Twinkle.

Just before he could pull far enough away, Twinkle let out a giggle and pressed her hoof harmlessly against Shining's muzzle. In response his eyes crossed and his tongue rolled out of his mouth, prompting a loud squeal of delight from both foals. Twilight giggled as well, and Shining was sure he even heard his mother chuckling behind his back. He just shook his head to refocus his vision, before he looked to Twilight and gave her a warm, but unamused, smirk.

"You have a good day, Twiley," Shining spoke in a loving and caring tone as he leaned in close.

"You as well, dear," she replied, her tone matching his, as she leaned forward, letting their lips meet in the middle.

The kiss was short and sweet, but carried lots of affection between the two. Once it was finished, Shining nuzzled her cheek, prompting another giggle from her, before he pulled away and walked to the fridge. Opening it, he grabbed two cutie mark oriented lunch boxes, along with an orange for the walk to work. Once he had a hold of everything, he turned to the kitchen window to gauge what his day would be like.

The sun was shining, and he knew today would be a good day.

Chapter 5.5- Five Months later

View Online

Shining woke from his slumber, a dream already fleeting from his memory as the sound of an alarm blaring, filled his ears. He blinked repeatedly as his eyes started to adjust to the area around him, until he focused on his window and noticed it was pitch black outside. He shifted his body in an effort to wrap the covers tighter around himself, and regretted it instantly as tired muscles strained and ached. Work had taken its toll from the previous night on him as he found his body nearly unresponsive. Night shift guard duty was something he was getting used to, and looking towards the clock, he sighed as it said 21:17. His next shift was less than 2 hours away.

Finally he summoned up enough strength and pressed the silence button on the clock, before his razzled mind found a brief moment of reprieve. No longer distracted by the noise, he started to regain his senses slowly, until he felt a line of drool on the side of his mouth, falling to the bed below. For a moment his eyes refused to focus and they stayed half lidded and heavy, until he let out a big yawn, causing them to momentarily go wide and reveal how bloodshot they were.

"Ughhh, I still feel so tired," Shining whined, not wanting to get out of bed.

As much as he wanted to fall back asleep, his stomach grumbled, causing him to pout and realize he didn't eat anything before he passed out earlier in the day. Normally he would snack on something after his shift was over, however the previous night left him so exhausted that he got home and went right to bed without even saying a word to anyone else.

Laying in place, his mind slowly grew more alert, and after a few long seconds of deathly silence, he noticed it was a bit too quiet for his liking. Normally his mother would be up and about making noise around the house as she either cooked, cleaned, or even sang to himself, and his father would have the radio on loud enough that Shining could pick it up if he listened hard enough, but for some reason, none of the above was present at all.

"Is everyone out?" He grumbled, pulling his tired body up.

His back cracked and popped as he sat himself upright and he felt a head rush greet him... both to his skull and his loins below. He let out a moan of displeasure as he felt a heavy throb greet him both areas, and though he tried to calm his mind and not think it, morning wood was starting to take its effect on him.

"Horsefeathers! I’m too tired to deal with that right now," he cursed as the head of his erection poked at the blankets.

It got hard fast, thanks to a growing sense of horniness starting to cloud his mind. A small wet spot was present where the head of it was, bringing up a brief memory of what he was dreaming about. A glimpse of purple played in his mind as the sight of his sister greeted it, and it was accompanied by a lewd display of his spreading her legs for his amusement. A hard twitch greeted him, and Shining could only whine at his depraved thoughts.

It had been a few months since he first got Twilight pregnant by accident, however ever since that day, he started to fantasize more and more about her. He never acted on those fantasies, fearing his parents would scold him or belittle him more then they already did, his mother especially, however Twilight was also showing him more affection when they were briefly alone together.

The first few months were an interesting mix of depression and worry for the young mare, however at some point Twilight started to become a lot more eager to be a parent. She started reading more books on parenting, and spent a fair amount of time at the castle, no doubt spending as much time as she could with the princess before she would end up giving birth. Now here she was 5 months into her pregnancy, happy as she could be and spending lots of her off time with Shining.

The sound of hooves walking down the hallway outside the door, alerted Shining that someone was indeed in the house. For a moment he wondered if his parents were home, until he heard the sound of Twilight humming a tune to herself, causing a smile to surface on his face.

“You up, Shining?” Twilight asked as she came to his door and knocked on it a few times.

“Yeah, just woke up,” Shining answered loudly, his voice mostly mumbling, but still coherent enough to make it out.

“Mom and dad had a work meeting so it’s just us right now,” she retorted with eagerness in her voice, causing Shining to raise an eyebrow.

For a few moments his mind tried to figure out what kind of work meeting was happening, and during that time, Twilight opened the door, causing the light from the hallway to flood in. As it did, Shining quickly realized his covered erection was visible as a beam of light greeted it, and feeling his cheeks start to burn, he put his hooves down on it, in an effort to smother his horniness.

“Bad timing?” Twilight spoke with a chuckle as she turned her attention to his face.

Shining said nothing, too embarrassed that he was caught off guard, however his thoughts calmed down as he could see his sister fully. Being a fair amount into her pregnancy, she was a bit more plump and round, however it didn't turn him off at all, in fact she looked beautiful. He didn’t know why he thought as such; he had always seen her as his little sister, yet now here he was fantasizing about her in his sleep and felt his heart swell with pride whenever he saw her walking around. He didn’t know what to make of it, his young adult mind operating on it’s own intuition while he seemed too stupid to keep up with it.

“Yeah, bad timing,” Shining replied with a smile as he calmed himself down and rolled onto his side so his erection wasn’t visible anymore. “How are you doing today, Sis?”

“I’m doing good,” she answered with a soft sigh as she turned her attention back down the hallway. “i'lI make you some breakfast and get some fresh coffee brewing for you in a jiffy, by the way.”

"Thanks, Sis, I really appreciate it." Shining’s smile grew at the prospect of hearing that, however he became momentarily distracted as his eyes looked closer at Twilight, specifically her horn, and saw a blanket of magic covering it.

Before he could wander further, Twilight flashed him a smile and continued her way down the hallway, and trailing behind her, whilst floating in mid air was a book of some sort. He only saw it for a few brief seconds, but his eyes lit up.

Sex & Pregnancy?” Shining muttered the title of the book to himself, his back legs clenching in response.

He laid still for several moments, his mind beginning to wonder if Twilight was looking to become more sexually active with him, however he didn’t want to think too much about it, in case he got so hard he would have to rub one off before work. Instead he let out a deep sigh, threw the covers off his body and began to climb out of bed.

***

The scent of coffee filled Shining’s nostrils as he walked down the hallway towards the kitchen. Faint yet energetic humming could be heard coming from the kitchen as well, signaling Twilight was in a rather good mood for that evening, and while it was a welcome noise, an ache between his legs made him regret not jerking off quickly. He walked awkwardly down the hall, his penis fully erect and swaying with every step, and though he had covered his body with his bathroom robe, he still felt embarrassed and silly. Despite his feelings, he ignored it the best he could as he turned the final corner, and once the kitchen was in full view, his mind was able to relax.

“Coffee is on the table, and just how you like it,” Twilight spoke over her shoulder.

Finding his eyes latched onto his sister, he briefly stared at her plump body, before his vision turned slightly in order to see what she was doing at the counter. A jar of pickles and a container of vanilla ice cream were present, and though it was an odd combination, Shining held back a chuckle as he walked towards the dining table. On the table itself was a plate of freshly toasted hay, a single poached egg, and thinly sliced radishes, neatly decorated in the form of a crude smiley face, most likely a form of amusement for Twilight, and beside the plate was a steaming cup of coffee. Getting closer to it, Shining picked up an extra scent, before his eyes widened and his lips curled into a smile. He could smell a shot of espresso in the coffee, and noticed Twilight had already added his two signature creams to the mix, thanks to the diluted color of it.

“Thanks a bunch, Sis,” Shining spoke out, causing Twilight’s own smile to widen, along with her swishing her tail.

She looked over her shoulder and flashed him a smile, before she went back to filling up a bowl with ice cream. Refocusing on his coffee, Shining lit up his horn and wrapped a layer of magic around the mug, before slowly lifting it towards his face. Hot steam flittered in his vision before he closed his eyes, took in a big whiff of it, and proceeded to take a sip. As he drank the hot beverage, his eyes went wide as the espresso hit him instantly. His eyes watered and he felt a surge of life course through his groggy mind, until he finished taking the sip and put the coffee back down.

“Awwweeee, that hits the spot,” he groaned loudly, his watery eyes barely able to make out the kitchen around him.

“Glad to see I got it right,” Twilight spoke with a chipper tone in his voice as she started to turn herself around.

Though his vision was blurry, Shining could make out two items floating in mid air, suspended by Twilight’s magic; the bowl of ice cream with sliced pickles in it, and the book he saw back at his room. Bringing his foreleg up to his face, he wiped the blurriness away just in time to see Twilight sit down at the table with him, before his eyes latched onto the full title of the book. Sex & Pregnancy; Your Pregnancy Sex Drive Explained. The book itself was a simple brown cover with only the title and name of the author displayed. Seeing the full title up close reminded Shining that he was still hard below, and it was starting to get to the point that it was beginning to get too tiresome to ignore.

For a few minutes there was silence in the air, barring the exception of cutlery and occasional chewing of hay or radishes. While they sat there, Twilight casually ate and kept herself focused on the book she was reading, which in turn, caused Shining to fully wonder if she was going to end up popping the question to him soon. They were rarely at home alone, and much like Shining, Twilight knew to not engage in sexual act when the parents were around, out of fear of being scolded for her actions. However whenever they had a few seconds of alone time, Twilight was always trying to convince Shining for a quick rutting session, yet they never could act upon it with their parents around. If anything, it was the optimal time to get all the pent up sex out of their systems for a bit.

“What’s the book about?” Shining asked, hoping to provoke a conversation.

“Mainly a book about how it’s normal to be sexually active during pregnancy,” Twilight answered, her eyes staying peeled to the book. “Plus it also gives advice on what kind of sex positions a pony could try.”

“Really?” Shining asked simply. “What position does it highly suggest?”

Twilight’s lipped curled slightly as she quickly flipped through the pages, just enough for Shining to notice her smile.

“Side-by-side sex from behind,” She answered, before clearing her throat. “Lying on your side is one of the best sex positions for pregnancy and extra intimacy. This variation on the classic side-by-side sex position allows for your partner to enter you from behind, whilst letting the both of you express that same passionate closeness you would have felt prior to your term. Lie with your partner facing your back, and be sure to keep some pillows handy for extra support around your belly as your pregnancy progresses. Penetration tends to be shallower in this position, and that is a good thing, because deep thrusts may become uncomfortable in later months.”

As she stopped speaking, silence filled the room as Twilight finally moved her eyes up and locked them onto Shining’s.

“Parents are out for a few hours and we’re finally alone for the first time in a few months,” Twilight spoke again, putting the book face down on the table. “So do you...”

“Don’t bother asking because I’m already saying yes,” Shining spoke in return, his tail flailing about in an excited manner.

“Are you that excited?” Twilight spoke with a chuckle.

“I’ve been horny ever since I woke up,” Shining replied, his own lips starting to curl.

“Figures as much.” Twilight looked at Shining’s plate. “Finish your meal and we’ll head into the spare room. Those sheets are due for laundry tomorrow morning so mom and dad won’t suspect a thing if I throw them in tonight.”

“Smart thinking,” Shining told her as he looked down and saw he had a few strands of hay left, along with a single radish off to the side, before he lit up his horn, picked up the last bit of it, and stuffed it all in his mouth. “Whenever you’re ready to go,” he finished, whilst still chewing.

Twilight rolled her eyes and shook her head, but it was enough for her to get out of her seat and put her empty bowl in the sink. As she walked by, Shining noticed that she was holding her tail up more then before, and managed to take a quick glance at her rear. Though they were ponies and usually in the nude daily, Shining grew more excited that he was going to plow his sister within the next few minutes. His penis flexed in response and he was sure a bit of pre was already coating the tip of it; a sign that he was long overdue.

Quickly getting out of his chair, Shining followed closely behind Twilight, never taking his eyes off her pussy as they walked around. Twilight, very aware that her brother was staring at her rear nonstop, shimmied as she walked, giving the horny stallion a small show, and though some days she felt fat with her growing body, seeing Shining watch her with such sexual intent that he was practically leaking as he walked, made her feel more comfortable, excited, and a small sense of control over him. She could sway her hips to the side and Shining’s eyes would move accordingly, causing her to giggle as she looked over her shoulder at him.

“You really like what you see?” Twilight asked, a bit self conscious about her weight, starting to poke back into her head.

“How could I not?” he answered back as he made eye contact with her.

“Does my bigger body not bother you?” she asked.

“No?” Shining answered, almost like he was confused by her question. “If anything, you’re growing so nicely and beautifully.”

“Really?” she probed further.

“Yeah, you look great, Sis. ” Shining accompanied his words with a smile. “So don’t feel fat or ashamed with the way you look or anything like that.”

Twilight blushed at his words. He was a bit naïve and corny in the way he spoke, but Twilight knew his words were genuine and knew she could put her worries to rest.

The walk to the room was quiet afterwards, however once they made it to the door and opened it, Shining took his eyes off his sister and looked to the bed as Twilight turned on the light. The room was remarkably bare for being an extra room, with the only things inside of it being a bed and an old dresser that had old knick-knacks in it. Movement from Twilight caused Shining to refocus on her as she walked to the side of the bed and paused for a moment. A dull brown cotton blank laid neatly across the bed and two firm looking pillows sat at the head of it in Shining’s side vision, but he was more concerned about Twilight climbing up.

“It’s a bit higher then your bed is,” Shining noted as Twilight put her hoof on the bed, almost like she was gauging its height. “Hold on, let me get you on.”

With little warning, Shining lit up his horn and wrapped his magic gently around Twilight’s entire body, before picking her up, making sure to put extra magic on her stomach so it wasn’t uncomfortable with her.

“Thanks, Shining,” She spoke with a smile as she landed on the bed.

He smiled back but didn’t say anything as Twilight was quick to grab the pillows on the bed, before laying on her side and putting the pillow under her stomach. Once she was settled and her stomach was comfortable, she let out a deep sigh and laid her head on the bed.

“You okay?” Shining asked, noticing she didn’t move a muscle for a few long and drawn out seconds.

“I’m fine, just a bit tired from walking around all day,” she answered as Shining hopped on the bed and laid next to her.

“Are you fine enough to be doing this?” Shining questioned further, before placing a hoof on her thigh and gently caressing it.

Twilight chuckled for a moment. “I’m absolutely fine enough to be doing this.”

Shining smiled in return and started to get himself into position. From how Twilight described it, all he had to do was lay down and rest the underside of his body against her back; similar to how they shared the bed occasionally in the past, without the lewd machinations included, and quickly shimmying his body, he did just that while making sure the head of his hard erection was resting in between her thighs. Now they were close and laying together and enjoying the closeness of the two of them for the moment, Twilight rubbed the back of her head against Shining’s neck in an affectionate manner.

"Been awhile since we were able to share the bed like this," Twilight purred as she swayed her hips, causing Shining's erection to move with her.

"Seems it was worth the wait," Shining purred back as he nuzzled the tip of his muzzle against her ear, before he started to jerk his hips back and forth.

For a moment, she giggled and her ear flopped in response, before her attention was grabbed by Shining moving a hoof to her hindleg and slowly lifting it up. His hips moved again and Twilight thought he was about to line himself up for entry, however the motion was brief, until it was followed by a hum of magic. Without warning, Shining focused his magic over the entirety of Twilight's pussy, and began to slowly stroke it up and down, causing the small mare to let out a deep sigh of relief.

There was silence between the two as both focused their attention to the spot Shining was rubbing, however for Twilight, she found herself staring more at the tip of Shining's erection. A bit of pre-cum was very visible on the tip and she could see it flex from time to time, making her wonder just how sore he was. She half expected him to stuff it inside of her and rut her into a stupor, yet to her surprise, he seemed more interested in rubbing her down below. Whether out of concern to make sure she was nice and wet for entry, or out of fascination of playing with her privates, Twilight didn't know… nor did she even care to ask. His movements were slow and jerky, yet unsure in a way, almost like he was trying to gauge it. However soon the field of magic started to spread out and pick up a bit of speed, constantly applying pleasure to the entirety of it whilst kneading it in a brisk manner. An enjoyable feeling nonetheless, and Twilight couldn't help but periodically moan when he kneaded it the right way.

Finally after a few minutes of rubbing, Twilight found her own breathing starting to speed up, thanks to Shining's ministrations, and picking up on that, Shining knew she was ready for a rutting.

"How do you feel?" He asked, his magic dimming down until his horn went out completely.

"I feel great, Twilight with a smile as she gave her hips a wiggle. "But I would feel a lot better if you stick it in me."

Shining smiled in return as his eyes looked down at Twilight's pussy. He was successful in making her wet and noticed how puffy it looked. Her body was eager for penetration and his erection ached nonstop as he jostled his hips and began to line himself up. As the tip of it brushed against her warm entrance, Shining could barely contain himself as he pushed the first few inches in with utter ease.

"Fuck…" he groaned under his breath, the words never making it to Twilight's ears as she let out a deep moan in return.

As he came to a stop, he noticed he wasn't able to get much more of himself in, thanks to his positioning. Just under half his erection was in, but it was enough for him to enjoy the feeling and he began to quickly rut her. His movements were short and shallow, but they were fast and eager enough that the bed was squeaking underneath them. At first he worried he was going to quickly and not giving Twilight any sense of pleasure, however she moaned in tandem with his movements, almost making him want to pick up pace and fuck her even faster. He did his best to keep a steady pace, but his body had other plans for him. Being too pent up since he awakened, he felt his erection constantly throbbing and providing endless amounts of pleasure every time his cock rubbed against Twilight's inside. The intense feeling radiated throughout his body, coursing all over and eventually coming to his hooves, where he could almost feel them curling inwards the more he moved. He was in bliss, yet at the same time, he had great desire to cum.

Twilight's moans kept him in check, reminding him that her pleasure mattered as well. She was enjoying it, he could tell with ease. Her eyes were closed and her mouth hung agape with only soft and constant moans coming from it. Her leg felt limp in the hoof he was hoisting up, a sign she was enjoying herself immensely, and her backside clinched hard around Shining's erection, doing its part to coax as much feeling as it could. He couldn’t help but moan in response to the intense feeling, his mind wavering between autopilot and self-control as every continuous thrust caused the former to take more effect, little by little.

Soon the sound of the bed squeaking began to drown out both their moans and Shining knew it wouldn't be long until he came. It would come quickly, but before that happened, he wanted to make sure Twilight came first so she didn't get left behind. Thankfully he knew how to make that happen, and as a magical pop filled the air, Twilight let out a moan as Shining focused his magic on her clitoris.

"Sh-shining! Tha-that's…" She stuttered, unable to form words as her body writhed with bliss.

He rubbed it fast and vigorously, causing Twilight's once limp leg to come alive and squeeze downwards against him. Regardless he still kept her leg in the air and fucked her as hard and as fast he could go, even as she looked back at him with pleading eyes and erratic moans. His efforts were pushing her to a fast approaching finish, however he found himself on the verge of wanting to cum. Something clicked in his body and he clenched both his teeth and eyes as his oncoming orgasm was rearing its head. He couldn’t slow himself down, nor did he have any sort of willpower to limit himself anymore as his body kicked into auto pilot and he started to fuck his sister wildly.

“I need to cum,” he groaned apologetically as he nuzzled his face into Twilight’s mane.

She didn’t reply, too lost in her own lust to hear him. Her own orgasm was peaking as well, thanks to the combined assault by both Shining’s magic and his dick constantly smashing into her. Her body strained from the onslaught as everything in her being started to tightened up, and as she did, she felt Shining's operate his magic much faster and felt his erection go harder and deeper in her. She couldn't speak and instead could only muster small whinny's as her hooves clenched aimlessly at the sheets, until a loud grunt from Shining and a second pause from his thrusts came next. It was a brief sensation as she felt her brother’s cock twitch and flex inside of her, no doubt a sign he was in the process of cumming, however much to her surprise he sped up his thrusts once again to the same level he was once at.

"D-did you just…" Twilight moaned but stopped as Shining hugged her close.

"Damn," Shining groaned as he found himself starting to fatigue quickly as burst after burst of seed erupted from his erection and into his sister.

He didn't want to cum before she did, however with quick improvisation, he pulled his deflating erection out of Twilight and altered his magic so it was the same as a crude penis, similar in length and girth of his own. Twilight only got a moment of reprieve until she felt the magical erection continue off from where the real one finished.

"Ohmygosh!" she screamed as she grew quickly accustomed to the new appendage fucking her.

It was fluid, quick, and surprisingly flexible as carried a buzzing sensation with it, causing her to gasp and clench her legs around it. She moved her back leg down from Shining's hoof and felt a stronger sense of bliss and her lower body squeezed hard around the faux erection. She could feel it stretch and mold to her being and it was just the thing to send her body into overdrive. All corners of it rubbed against her insides and stimulated her senses so much that she felt her eyes starting to roll behind her head. She continued to moan loudly as she got fucked, dangling on the line of the incoming climax and infinite pleasure, until she felt her body give out and she came.

Shining watched quietly as Twilight moved a hoof to her mouth, covering it just in time to stifle a loud scream of pleasure as his eyes noticed her back legs start to convulse and twitch. She was cumming and making sure she had an orgasm worth remembering, he continued to move his magic accordingly. After a few seconds, he noticed her convulsions die down, and in return he slowed his movements down gradually until he came to a standstill.

"How do you feel?" He asked as heavy breathing from Twilight filled the air, before he began to slowly pull his magic out of her.

"Oh my gosh," was all she could mutter as she stared up at the ceiling.

Her mind could barely process what just happened to her as an euphoric sense of nirvana washed over her being, until she finally regulated her breathing and looked to her brother.

"That was... that was great!" She spoke breathlessly, her expression turning into a big smile.

"Glad to know I did a good job," Shining spoke with a smile as he laid against the bed and hugged his body close to hers.

"You work well when your... under pressure," Twilight chuckled as she smiled at him, before lowering her eyes down to her legs.

The bed and her backside were drenched in so much cum, she was amazed at how much of it there was to see.

"Sorry for the mess," Shining replied with a sheepish smile as he looked down at the mess he made. "I really needed that more then I thought."

For a couple seconds, there was only silence between the two of them as each basked in their respective afterglow, however Twilight made sure to nuzzle her body against his with affection.

"Hopefully we can do this more often," she cooked, shimmying her hips against his.

"Agreed," Shining spoke with a chuckle as he nuzzled her mane in return. "If mom and dad are gone for more late night meetings like this, we definitely should do this more often."

"Hope so," Twilight replied as she rested her head against the bed. "I don't think I'll last another 5 months without any sex."

"Me as well, Twi. Me as well."
