Finally, after five long days, Shining Armor was alone. It had been a long wait, eagerly tapping his hooves at school today, watching the clock so closely his vision began to blur, but as he shut the door and tossed his bag to the floor, he could practically taste it in the air. The time was finally here. An entire weekend home alone!
When his parents reminded him of their anniversary trip, at first he thought nothing of it. Last year it was Manehattan. Las Pegasus the year before. He grew accustomed to looking after his little sister from time to time, though Twilight was much too old for a foalsitter these days. However, this year's plans would take the happy couple eastward to Fillydelphia, and when Twilight begged to accompany them, Shining began paying attention. She'd never been that far east, and predictably, she was interested in the Fillydelphia library and its five-hundred-thousand-some-odd books. Their parents weren't too keen on the idea, having romantic plans for the trip, but they were no match for their daughter. All she had to do was make a cute face and drop the line about a "great learning experience" and they instantly lost their authority over her.
And so here stood Shining in the living room, hatching plans for his precious, precious alone time. It was Friday afternoon, and he had the house entirely to himself until Sunday night. He considered jumping for joy, but he restrained himself. After all, he had the whole weekend to do plenty of jumping.
What to do first? So many possibilities! He could raid the pantry of all the junk food. He could build a fort of sofa cushions and sheets and pretend he was a little colt again. He could put on his awesome music and turn it up as loud as he liked. He could even bring Cadance over and they could...well...do what his parents would be doing if Twilight hadn't invited herself along with them.
Suddenly, Shining had a thought. A dark thought. It chilled him to the bone and stopped his breath. He rolled his eyes and groaned at the realization. There was something in the way. Something had to be dealt with before any of this fun could take place. Something more evil than any villain Equestria had ever seen.
Shining had homework to do...
That day in the living room, he knew. Homework was a cruelty inflicted by bitter teachers, and weekend homework was invented by the most evil creature in history to make students' lives miserable. So close to graduation, such things were beneath him! Alas, it had to be done. He knew he wouldn't be able to enjoy himself until he got it out of the way, so he ruffled through his bag and set out to make this as painless as possible.
* * *
Four hours... Ugh! Four long hours he would never see again. It was such a shame. Evening was already here, and he was just now finishing up. The assignments had been easy enough, but Shining was distracted by thoughts of Cadance. He'd planted the seed earlier, and now he couldn't get her out of his head. He'd eventually settled on his back, levitating a book to keep the paper rigid and writing with his magic, and in this position, it was very easy to drift off into a reverie about his girlfriend. As he finally scrawled an answer to the last question, he shut the paper inside the book, tossing it aside.
Shining took a deep breath and let it out slowly. Things had stirred between his legs, something he wouldn't dare allow happen in the living room...except on this rare occasion. He looked at the clock. 7:21. "Shoot," he muttered. No way would her parents let her come over this late. Too bad. He was in the mood. Then again, nopony was here. He could do anything he wanted! He could clop right here on the sofa and nopony would know!
And Shining thought, "Why not?"
A quick trip to the linen closet for a towel was all he needed before lying back down with an excited fluttery feeling in his belly. For something so mundane, it sure felt naughty. Masturbating right here in the living room! He set the towel within hoof's reach and began touching himself. It wasn't completely hard yet, but it would be soon. He stroked over it a few times, feeling it growing. Thoughts of Cadance had put him in such a mood, and it wasn't long before he reached full size. Once he did, he really got down to business, paying special attention to the tip first, making himself groan and shift. He shut his eyes and let his hooves take him away. Only in the darkness of his room did he ever do this, and even then, he would usually wait until everypony was asleep. For some reason, doing it here in this open part of the house under cheery lights enhanced the experience in a way he didn't entirely understand. It felt wonderful, and that was good enough.
Down his penis he went, now stroking the ring. He loved it there, and Cadance knew it. In the empty house, there was no need for modesty, so he moaned in pleasure, imagining her soft hooves and tongue. It was all starting to be too much. He pulled things back a little, savoring the sensations that he craved. Tomorrow she'd come over and they could do whatever they wanted, wherever they wanted. Right here on the couch, or up in his room to use the bed. They could just put a towel down and he could mount her anywhere in the house. Might even do it on the dining room table. Who knows? Anything was possible in Shining Armor's current state of mind. "Yeah," he declared to himself before moaning once more. With his orgasm looming on the horizon, he decided to delay it no longer. Imaginary Cadance was suckling on his tip, and Shining was eager for his climax to cripple him and send him flying high.
Shining opened his eyes and reached for the towel to place over his chest, but there was something extra in the room with him. He knew it shouldn't be there, and yet there it stood at the foot of the stairs, looking at him. He froze, mouth agape, one hoof on the towel, the other stuck to his penis as if by glue. Movement was impossible. Speech was impossible. The burning in his belly meant he was in big, big trouble.
"Guess you weren't expecting me to be home," said Twilight.
Lying there, trying to unfreeze himself, Shining watched Twilight trot casually past him into the kitchen. It was certainly embarrassing, but at least she wasn't freaking out. Maybe he could avoid an ugly episode after all. "I thought..." he started nervously, "I thought you were going with Mom and Dad," he called over the back of the sofa.
"I would have gone, but I felt guilty for intruding on their romantic time, so I changed my mind."
Under better circumstances, Shining might have admired her selflessness. "I didn't see you this morning...or at school."
"Mom and Dad already had me excused for the trip. And I was awake late studying, so I didn't want to get up early." She paused. "I hope you're not suggesting this is my fault, mister."
Twilight losing sleep over books. Nothing new there. "I'm so sorry, Twily..." Shining Armor scrambled to a sitting position, his back to her, and tried desperately to will his erection away. "I really thought I was alone."
"Look, Shining, all stallions take care of their business," he heard her say as she rummaged around behind him in the kitchen, "but most of them do it in the privacy of their own rooms. You know, where their little sisters won't walk in on them."
"I really am sorry. Hope you didn't see too much." He thought for a moment, and then looked back at her. "How long were you standing there, anyway?"
"Oh, well...you know...just..." she mumbled something as her head disappeared behind the counter.
"Huh?"
"What?"
"I didn't catch that."
"Catch what?"
"What you said."
"When?"
"Just now!"
"What are you talking about?"
Something wasn't right. "Twily, I know I'm the one in trouble here, but really... How long were you watching me?" he asked sincerely.
After a few moments of nervous silence, Twilight finally gave him a straight answer. "Just a few seconds," came a shy voice from behind the counter.
Shining furrowed his brow. By the sound of things, that was what Twilight herself would call a rather conservative figure. Was she testing him? Gauging his reaction? The more Shining thought about it, the more it frightened him. The house was supposed to be empty, so he'd let his guard down. He'd been deep in his fantasy with his eyes shut. For all he knew, she could've been standing there nearly the whole time! Something told him to let it go rather than press the issue. Surely their relationship would be better for it.
It was around this time that Shining Armor realized two things. The first was that his erection still lingered, stiff and full as ever. Not much of a surprise. He'd been so close, not even the shock of being caught could stem the tide. His best hope now was that Twilight would be a good sister and allow him a relatively painless way out of this. Then he'd be free to go upstairs and finish his business.
The second thing he realized was that the kitchen had fallen silent. Shining looked over his other shoulder. Where'd she go?
"Twilight?"
Silence. Had she slipped past him somehow?
"Twily?"
"Why are you still erect?" she said as she plopped down next to him on the sofa.
"What the hay?!" Shining nearly jumped out of his skin. He tumbled over the arm of the couch and hid his lower half behind it. "I'm trying not to be!"
"You don't have control over it?"
"Of course I don't!"
Twilight looked positively dumbfounded. "Oh, wow... I thought... I guess I just assumed..."
"No! I mean, thinking about stuff helps, but it's totally involuntary."
"Wow! How do you keep it from just...popping up?"
Shining huffed. "Why are you so interested in this?"
"Well, it's kinda what I was...studying...last night."
And just like that, it all made sense. "I see..."
"It really is fascinating material. Especially stallions. I've learned a lot."
"Listen, kid...I don't think this is something for brothers and sisters to be talking about."
Suddenly, Twilight's smile vanished. There was anger in her eyes. "Why does nopony want to discuss this subject?! Not Mom, not Dad, not Cadance. None of my teachers. I even asked Princess Celestia! You know what she said?"
"I-"
"Nothing! She just recommended some books I've already read, and they all leave out too much detail! What is so bad about this stuff?!" Her eyes lingered on his for a moment before falling to the cushions, where she stared idly.
Shining was at a loss. He had no idea she was so frustrated over this. "It's just..." He searched for the words, but none were there. "It's one of those things that you don't..."
"I just wanna see it," she said, looking back up at him. "And maybe ask some questions. I won't touch it or anything. I just wanna look at it. Some of the books have drawings, but...drawings aren't real life. I want to see an actual penis."
Shining shook his head. "Twily, why in Equestria w-"
"Pleeeeease? Come on, I won't tell anypony. Pretty please?"
Shining groaned in nervous embarrassment. The thought sent his heart soaring into his throat. Was he really considering this? What would their parents think? What would Cadance think? He stared her down even as she pleaded like she used to plead for a second bowl of ice cream. Those eyes. They were the same eyes she used on their parents, and it worked on her brother from time to time, as well.
This was one of those times. Twily wouldn't give up. She had the basics, but he'd never known her to be satisfied with the basics. She wanted to know everything about everything. After a long sigh through clenched teeth, he finally gave in. "You promise not to tell anypony?"
Twilight nodded gleefully.
"I mean anypony. Not Mom or Dad. Not your teachers. Especially not Cadance or Princess Celestia! And no touching. Don't even ask."
His little sister nodded again, and he rubbed his face, wondering what he was getting himself into. Still rock-hard, Shining Armor crawled out from hiding. He didn't particularly want to, but something dragged him back to his seat. An overwhelming desire to help his sister? Maybe... Or maybe he was just horny out of his mind. A bit of both, he suspected. In any case, he reclined against the back of the couch, cock standing straight up like a flagpole as he stared blankly at nothing. She'd already seen it only moments ago, but even that knowledge wasn't enough to comfort him. He blushed so hard he thought his face might burst.
* * *
Twilight Sparkle on the other hoof was captivated. She hadn't been afforded a close look at it earlier, and she leaned over to inspect it like one might inspect a strange new animal. "Wow," she uttered. Saying her brother's penis looked like the pictures in her books would be an insult to her brother. Truly, it was beautiful. Solid black all the way from the tip to the base, except for a small patch of pink on the right side, which she thought was adorable. Its impressive thickness made her legs weak. For a moment, Twilight was acutely jealous of Cadance. Her former foalsitter was the luckiest mare in Equestria. "It's..." she stared with eyes practically aglow, "big."
* * *
"It's a penis, Twily. They usually are." Though he didn't show it, Shining couldn't help but feel a slight tingle of pride. Any stallion would love to have a girl admire his equipment...but this was certainly different.
"Yeah, but...good grief. Where does it all come from?"
"I thought you knew a lot about us stallions already."
"Like I said, the books were a little vague on some points," said Twilight.
Shining shrugged. "It's real boring technical stuff. Has to do with the way it expands and this ring in the middle here," he said pointing it out and somehow blushing even harder as he drew her attention to it. "I don't really remember all of it."
"That's so neat," said Twilight, inching ever closer. That something so large had been hiding between her brother's legs all this time... It was the most incredible thing she'd ever seen.
Shining replied with an unenthused, "Yeah..."
Twilight wiggled closer still and eyeballed the big thing like it was edible. "Hmm..."
Shining raised an eyebrow. "What?"
"It's just...perfect. All the proportions. The color, the shape, your testicles. Everything seems to be perfect."
This felt more like an awkward doctor's visit. Never in his life had Shining Armor felt such a strange concoction of pride and embarrassment. "Thanks, I guess."
Twilight tore her eyes away from it long enough to look up at her brother. "Can I touch it?"
Shining grunted. "You said you wouldn't ask!"
"But when am I gonna get another chance like this?"
Shining rolled his eyes. "I dunno... Maybe when you get a coltfriend?!"
"That's too long to wait," said Twilight in a very matter-of-fact way. "Plus, I'd like to have a little experience by then." She gazed down at it again. "It's very sensitive, right? Won't it feel good?"
Shining chuckled. "Yeah, that's...kinda the problem."
His little sister looked back up at him, her face having taken on a rather serious expression, and then came the question. "Why?"
That stopped Shining Armor in his tracks. For all his maturity and resistance, he suddenly went blank as a newborn's flank. He couldn't think of a single reason why it would be wrong for Twilight to make him feel good. Both ponies knew Shining Armor's heart belonged to Cadance, but this was somehow exempt from the normal boundaries. The very fact that Shining was caught for an answer spoke volumes, despite realizing that his unfinished session was likely affecting his judgment.
Shining sighed heavily. "I can't believe I'm letting you do this..."
"Yay!" Twilight clapped her hooves happily.
At this point, Shining knew Twilight wanted to keep this a secret as well - perhaps even more than he - but his cautious side made one last appearance before being swallowed up. "Just please don't tell anypony, okay?"
"Of course not." With that, Twilight gingerly reached over with a single hoof and touched her big brother's penis. Just on the shaft, halfway between the tip and the ring. Slowly, she let her hoof glide upward until it reached his more sensitive areas. It graced across the top and Shining twitched. Twilight looked up at him with a casual smile and grasped it with the other hoof, holding it in place while she stroked back downward. She began exploring the entire structure of his penis, surveying every facet of it with both hooves. All the way down to the base and back up again.
"Which parts are the most sensitive?" she asked with genuine interest.
Shining hesitated. He felt as though he'd be betraying some expensive trade secret if he told her the truth, but... "The tip feels best. And the ring in the middle is pretty good, too."
As she touched him, Shining knew he should be outright disgusted, but all he could feel was the tenderness of her hooves. She touched his ring, and he twitched again. The feeling was not unlike when Cadance touched him, but there was something else, too. Some extra sensation deep down at the base of his spine that he couldn't identify. Trying to focus on it was exciting. This strangely intimate examination by his little sister made him feel like a young colt discovering himself. In just a few moments she'd found his favorite spots and was exploiting them. As he relaxed under his sister's touch and sank comfortably into the cushions, he finally admitted to himself how much he was enjoying this.
"So, how close were you?"
Shining thought he knew what she meant. He just hoped he was wrong. "Close to what?"
"You know. Orgasm. Ejaculating."
Hearing his little sister say those two words was like a hammer to the head, and he nearly fell over. But again, he was taken aback by the way she spoke so calmly about these things. He was drawn in and compelled to give an honest answer for every awkward question. "Close... Really close."
"Really close?"
Shining nodded. "Like...I was reaching for that towel."
Twilight's hooves stopped. She looked a bit put off at the thought. "You use our towels to...clean up?"
"I wash 'em afterwards."
"That's still a little... I mean, can't you just use tissue or something?"
Shining burst into laughter at Twilight's relative innocence. "I guess your books did leave a few things out. Tissues don't cut it, Twily. I'd use up half the box on one session," he confessed before he could stop himself.
Twilight blinked. "Is it really that much?"
Shining nodded nervously.
"Wow..." Twilight stared down at the big thing in her hooves. "Can I see?"
How far was he willing to go with this? She wanted to watch him orgasm? He couldn't imagine a more private, vulnerable moment in which one pony could possibly see another. It was an experience he'd only ever shared with Cadance. To have his sister see him in that state... The thought was frightening, but he had to acknowledge his curiosity. The question should have carried more weight, but Shining Armor found his boundaries stretching farther and farther. What would that be like?
Against his better judgment, Shining muttered an uncertain, "Okay..." He gazed at the purple hooves still attached to his member. "But I should probably lie down...like I was before...because...messy," he stammered.
Twilight removed her hooves from her brother and hopped down to give him room. She sat in front of the couch, watching with intense interest as her brother lay down across the cushions and began masturbating before her very eyes.
"This is so weird," said Shining as he began to fully commit to his stroking. With Twilight just inches away, it wasn't as easy as he'd hoped. He shut his eyes and tried to pretend his sister wasn't watching. He tried instead to think of Cadance. For a moment, it actually worked. His earlier reverie involving her mouth began to return. Her luscious body, perfect rump...talented tongue...
"Does it feel good?"
Twilight snapped him out of it. "Of course it does. I'm masturbating," he said, slightly annoyed.
"Sorry. It's just, this is really interesting. Are you thinking of Cadance?"
"Mmhm." Shining closed his eyes again, but before he could even try to lose himself in thoughts of his girlfriend, Twilight spoke up again.
"Getting close?"
Shining's hooves stopped. "You're not making this easy, you know," he said as he glared up at the ceiling.
Twilight clamped her hooves over her muzzle. "Sorry, sorry. I promise I'll be quiet."
With little hope that she would keep that promise, Shining slowly brought himself back into a good rhythm. The thought of what they were doing kept nagging at him. On one hoof, he knew it was strange, to say the least. But on the other hoof, the idea that Twilight was watching him do this... It actually seemed to make things more exciting. Eyes shut, Cadance in his head, he approached the orgasm he'd been denied earlier with far less trouble than he'd imagined.
Hooves at his tip, he contained all his exclamations of pleasure except one. A single soft moan leaked from Shining's throat. For some inexplicable reason, he was almost more embarrassed about that than everything else. Soon, that embarrassment gave way to something much nicer as he felt himself nearing the edge. Shining turned his head to see Twily staring right into his eyes. He looked past her. "Can you give me that towel behind you?" he asked with a shaky voice.
Twilight looked over her shoulder and levitated the towel to her brother. "Are you about to ejaculate?" The question should have been completely rigid and scientific coming from Twilight Sparkle, but it sounded much more...flustered than Shining had any right to expect, and he turned it into fuel for his pleasure as he nodded.
Hoof still hard at work, he placed the towel over his chest, covering himself and protecting the couch. In the next few seconds, Shining guided his body into orgasm. For the briefest of moments, he forgot about his sister and allowed himself to enjoy the wonderful feeling. However, as soon as the first squirt of semen made its appearance and landed safely center-towel, Twilight gawked and squeaked. "Whoa!" She said nothing else, but it was too late. Shining Armor's concentration was broken. Even with his eyes shut, he could feel her staring...watching the squirts continue...watching him enjoy what had turned out to be a tremendously pleasurable climax. The idea should have been repulsive. And yet, he didn't stop. As the orgasm wound down and his sexual fervor was finally satisfied, the reality of what he'd just done began to set in.
With messy hooves, Shining lay still, trying to collect the pieces of his moral compass. Twilight was equally speechless, having watched the whole event with perfect attentiveness. When he dared to turn his head, their eyes met. It was less awkward than expected. A smile crept over her purple muzzle, and he knew his sister wouldn't stay quiet for long.
"Wow, that was so neat!" Twilight surveyed the many streaks of white fluid on the towel. "That's a lot of sperm," she declared, clearly impressed as she compared what she saw here to her books.
Shining caught his breath. "Semen," he corrected. "Or goo, or whatever. Just please don't call it 'sperm'. It sounds weird."
"Semen," she repeated, testing the word against her tongue.
Shining grimaced. He debated telling her that was actually worse, and he now preferred 'sperm'.
"Didn't last very long. Do it again!"
"I can't," admitted Shining with a bit of effort.
"Oh, come on. Pleeeease!"
"No, I mean I can't. Stallions need time to...err...recharge." He pointed to his shrinking erection.
"Huh... Really? The books didn't mention that, ether. How long do I have to wait?"
"I dunno. A while."
Twily groaned in frustration as his penis disappeared back into its home. Shining watched his disappointed sister play with the corner of the towel for a moment before he folded it up. Not bothering to move, he levitated the soiled towel into the bathroom, where he would later rinse it off before adding it to the dirty laundry. With all the evidence gone, he felt much better. Just like that, it was like nothing happened.
And yet, the look on his sister's face had become one he knew quite well. The disappointment had gone. She was thinking. Thinking hard. Hatching something. Their eyes met again and Shining considered issuing a preemptive 'no'.
Before he could, Twilight put a hoof on his belly. "Want me to try one of the spells I use on myself?"
Shining laughed and rolled his eyes. "You would have spells for that..." he said, not bothering to ask where she'd learned such taboo magic techniques.
"You don’t?" she asked sincerely.
Shining shook no.
"Heh, you're really missing out," she said, clearly quite pleased to have a one-up on her brother.
Shining felt a surge of warmth in his belly at the thought. "That good, huh?"
"You have no idea."
Shining raised an eyebrow in mild disbelief. "Really?"
Twilight nodded.
The thought made him nervous, but her hoof on his tummy began to sway his answer. "Alright," he said. "Go for it."
Suddenly, his sister looked a bit more mischievous than he would have liked. "Fantastic," she said. "We should probably move this upstairs, though. And get more towels."
Shining sat up. "Towels? Plural?"
Twily nodded, still wearing her sly expression as she moved toward the staircase.
Shining Armor suddenly wasn't so sure about this. Nevertheless, he rose from the couch and slowly followed his sister up the steps. On the way, Twilight lit her horn and opened the door to the linen closet. From it, she produced several clean towels, floating them above her as she reached the top of the stairs. "Your room or mine?" she asked, looking back and forth between the left and right doors.
Shining stopped behind her. "Mine, I guess," he said with a shrug of indifference.
* * *
Twilight entered the door on her right. In here, she noted the smell. She was no stranger to her brother's room, often forgiving the light mess to play games with him or assist him with a particularly difficult homework assignment. In her younger years, she even shared his bed in the event of a nasty nightmare. It was by no means an unpleasant or overbearing scent, but had she been blind, she would still know without a doubt what room this was.
It was messy, but any room was messy compared to her own, so she was more than used to it. The closet was wide open with miscellaneous objects poking out. A hoofball jersey lay on the floor - clean, thank Celestia. The trophy rack above his bed was slightly dusty, but acceptable. School books lay scattered across the desk on the opposite wall, but that was the kind of mess she liked to see. Shining did indeed have the larger of the two rooms; something for which Twilight was ever-so-slightly resentful, but she put that thought away and spread a few towels over the bed, covering it almost completely.
"Go ahead and lie down," she said.
* * *
Shining did so, but not without a nervous moment of hesitation. He might say she was being a little too organized about this, but Twilight was just being Twilight.
The moment he was in place, Twilight shut the door as a precaution and sat beside the bed. "Ready?" she asked, betraying the hint of a grin.
"Twily... Uhh... You know what you're doing, right?"
In a villainous voice, she bellowed, "You dare doubt my powers?" She pulled several of his sports trophies from their shelves and levitated them around her with a mock-evil laugh.
Shining happily shared the laugh, and it helped calm his nerves. "Alright, alright, put those back. Just...be careful messing around down there, okay? I don't want to wake up tomorrow with...like...nine testicles."
Twilight snickered. "I told you, I use this spell on myself."
Shining smirked at his sister. "Right, and there's clearly nothing wrong with you," he said playfully.
Twilight hoofed him in the shoulder.
"Kidding!" he said with a good-natured smile as he rubbed the spot where he was hit.
Twilight's expression dropped back into a serious one. "So... Ready?"
Shining Armor nodded and was immediately rewarded with an intense sensation between his legs. It bordered on pain, and he inhaled sharply through his teeth. "Aah! Aaah!"
Just as quickly, it stopped. "Too much?" asked Twilight.
"Yeah... Dial it down a little."
"Okay, lemme try again."
Another burst from her horn and Shining still couldn't handle the result. "Nnngg, stop, stop, stop, stop!"
"Sorry, sorry!" she said, looking thoroughly embarrassed. "The intensity is hard to gauge when you're using it on somepony else."
"It's okay. I'm guessing you've never done that before."
Twilight shook her head. "Just on myself."
"Okay...well..." Shining was now very intrigued. He couldn't deny that the aftertaste was rather nice. Perhaps the spell could feel good under the right circumstances. "Think of it like hot water in the shower."
Twilight paused. "I don't get it."
"You know, you wouldn't make the water scalding hot right away and just jump in. You need to make it warm first, then once you're in and you're getting used to it, you can start turning it way up. Think of it like that."
Twily nodded thoughtfully. "Alright... Let's try this, then..." Her horn lit up again.
This time, Shining Armor's body was greeted with a warm, tingly feeling not unlike that of approaching a particularly powerful orgasm. Had he not been ready for it, it might have been too much, but he handled it just fine. In a few moments, he was able to relax and bathe in the new feeling between his legs. He looked down there to see his sheath enveloped in an aura of purple. "That's... Wow, that's really nice," he managed.
"Great!" Twilight was quite enthused to finally get it right. She focused her magic just the tiniest bit harder and Shining responded with a happy groan. He was right. Easing into it was a good method.
Shining hadn't imagined he could get any closer, yet Twilight made it happen. He barely even noticed that he was hard as a rock. How long had he been like that? No idea. All he could think about was how thankful he was for his sister's meticulous nature right now. It felt like he could go over the edge at any moment, but she held him right on the razor tip. "That's really good. I really, really like that," he said, trying to will his way back to reality. He was officially impressed.
"Just wait," said Twilight. "Here comes the good part."
"What good p-" Shining had no time to complete his thought before his sister plunged his body into orgasm without even trying. The words caught in his throat and his hooves hit the bed. There was no time to reach for a towel. Semen leaked gently, but steadily from his cock as it surged with immense pleasure. He looked down to see the purple glow around his member had clouded and the flow of semen looked like a volcano oozing a thin trail of white lava. "Wh-" he tried. "Wha-" he couldn't quite get it out. Not with that feeling crippling him the way it was.
"Good?" asked Twilight with a knowing grin.
Shining could barely open his eyes enough to look at her, but he finally gathered the strength to say, "Amazing!" And it certainly was. The orgasm was going on for so long...that he actually had time to realize that it was going on for so long! He'd never done it twice in a row so quickly before, and this was something quite extraordinary. How had he never thought of spells like this? How had Cadance never thought of it?
Twilight extended her brother's orgasm as long as she could, but eventually his body gave out and the incredible feeling subsided. It pulsed slowly out of him and he was left squirming around on the bed with a very messy groin. Most of all, he just needed to breathe. He concentrated solely on that, blinking several times to look up at Twily once he had regained his faculties. She looked down at him with an almost motherly warmth. After such an experience, there was only one question on his mind. He took a moment to clear his throat and swallow before daring to speak. "Where in Equestria did you learn that?"
"A book," she said, cheerfully.
He cracked a smile. "What a surprise..."
* * *
Twilight just snickered, glad to see her brother was still lucid enough to be sarcastic after that orgasm. "Strange and Exotic Spells. There was a whole chapter on sex-related magic," she said. It had been one of the few helpful books she'd come across. In addition to orgasm-inducing magic, she picked up several obscure, but useful spells from other chapters. Spells to assist in cooking, which she taught her mother (very tentatively, so as not to sound insulting), a spell to keep vegetation extra healthy, which she used on the houseplants, and even a teleportation spell. She hadn't been able to get that one to work yet, but one day... For now, the orgasm magic was her favorite. "Found it in the no-foal area as soon as I was old enough to go back there. Of course, you'd know that if you went to the library once in a while."
* * *
"Wait, the library?!"
"Obviously I took it home before practicing that particular spell, Shining Armor," she said with a playful nudge to his shoulder.
Shining noted his erection. Even after that, it still felt like it wasn't going anywhere. "I just never thought about using magic that way."
"You always do it with your hooves?"
"Yeah."
"I like to start with my hooves, and save the magic for later."
"You gotta teach me that spell," he said, wearily.
Twilight giggled in excitement. "That's actually the most basic one. An easy sort of 'generic' orgasm spell. I don't use that one much. I use the advanced version." Shining's face lit up. He was about to say something, but Twilight held up a hoof to stop him. "And before you ask, it's for mares only."
"Oh..." He looked genuinely disappointed.
"Sorry, Shiny. The spell would just fizzle if I tried it on you. The anatomy simply doesn't work."
"Well...were there any advanced spells for stallions?"
"There was one, but I couldn't really learn it without the proper...apparatus."
"You totally did not just call my penis an 'apparatus'."
Twilight giggled.
"Do you still have the book?"
Twilight shook her head. "I learned this stuff years ago. Who knows if the library even has it anymore?"
"Shoot," he exclaimed.
After a brief thought, Twilight grinned. "Buuut...since I know the other two spells so well, I might be able to figure it out. I can try, but don't get your hopes up."
Shining looked like he did the morning of Hearth's Warming Day. "Really?"
"Just lemme know if it feels weird. I don't want to hurt you."
Preparing for another onslaught on his senses, Shining wiggled into a comfortable position and let his sister do her thing. In a quick moment, her horn lit up again.
"Does that feel alright?"
"I don't feel anything."
"Okay... How about now?"
Shining shook his head.
"... Now?"
"No."
"Nothing at all?"
"Nothing."
Twilight let her magic dissipate. She tapped a hoof on her muzzle, staring intently at her brother's nethers. "I was sure one of those would do it. How else would this work?" she quietly asked herself. A few more tries and nothing. Shining was starting to get discouraged.
"Twily, if you can't do it, don't wo-" She silently shushed him with a hoof. He could tell she was in the zone now. Once Twilight got to thinking about magic-related things, there was no stopping her. In a way, that made him more comfortable, knowing she would eventually figure this out no matter what. Rarely did his little sister ever falter in this field.
"If the... No... What if I compensate for...?" She lit her horn once more as she continued to debate herself and Shining suddenly felt something strange. "Anything?"
He gave a slow nod.
"Good?"
"It's... I dunno."
"But it's not bad?"
He shook no.
"That's perfect, actually. I think I've got it. Let me know if it gets better."
As Twilight gently increased the intensity of her new modified spell, Shining felt something stir within him. Something was happening that he did not understand at all. The base of his tail felt like the source, but there was no real epicenter. Shivers began in his legs and ended all the way up in his neck. It felt foreign, but not wrong, and his body seemed to welcome the intruder. He decided right away that he liked it.
"Better?" asked Twilight.
Shining Armor nodded in lazy contentment.
"Hah! Yes!" she declared happily. "Alright, get ready. Unless there's something seriously wrong with your insides, I think I've got this figured out."
"Okay." He mentally prepared himself, but no amount of preparation would have been enough. It hit him so hard he barely had time to realize what was happening before he slipped seamlessly into yet another orgasm.
It was far more deep and powerful than the last one. With a series of little gasps, all his thoughts went away as the wonderful feeling surged between his legs and streams of thick semen went soaring skyward. He couldn't believe how good it felt. It was like having two or three orgasms at once! His back arched uncontrollably, his muzzle agape. In his head, he searched for words that could describe it, but found none. The strength of it was almost frightening, and the force with which the streams of ejaculate came shooting out of him was unnatural.
His hooves desperately grasped at the bed, trying to hold onto the mattress as though he might float to the ceiling at any moment. This was unfamiliar territory to the highest degree. The orgasm Twilight had given him - continued to give him - was impossibly good! He had no idea his body could feel like this! The way his entire lower half tingled and pulsed and buzzed was absolutely surreal. It made his legs kick. Made his spine twitch. Made his voice quiver. All completely involuntary. It dawned on him only then that he had been moaning instead of breathing for quite some time.
Where normal orgasms seemed to drain him, this one did not. In fact, he felt charged! It was invigorating, and it just wouldn't quit, crashing into him in endless waves. As he looked to Twilight - who, he would later note, wore the most satisfied grin he had ever seen - he began to understand that as long as her horn stayed aglow, he would feel it. He was at her mercy. With all his will, he tried to tell her to keep going, but nothing except slurred gibberish came spilling from his mouth. At that moment, his sister had such power over him that he would have literally begged her to keep going if she stopped.
* * *
But she didn't stop. She pushed on, keeping her brother in a perpetual state of bliss that she knew all too well herself. Yet, while she was used to it and had learned to handle the intense pleasure, the way her brother rode the mighty orgasm was distinctly ungraceful - even clumsy - and she found the sight of it to be completely wonderful. She took in every moment, watching him spasm and convulse like she'd expected. Watching the streams of white liquid ebb to a trickle before finally drying up. Listening to shameless and effeminate moans that sounded like they could have come from a colt half his age. Watching his face as it contorted into the funniest shapes. It looked as though he was in pain, but Twilight knew better. Such a strong feeling was bound to have that effect.
* * *
Shining Armor had lost himself some time ago. At one point, he noticed that he'd stopped ejaculating, but the monstrous orgasm didn't seem to care. It burned just as strong as when it had begun. The smell of all that semen made his head swim. Not in his wildest fantasies had he pictured something like this enormously pleasurable experience. He had no idea how long he'd been enduring it. A minute? Two minutes? Three? He thought of asking Twilight, but still couldn't manage a single clear word. His little sister had effectively paralyzed him, and he loved her for it.
Almost as if she read his mind, Twilight spoke up. "Nice, isn't it? In theory, I could make it go on forever." At least, that's what Shining Armor thought she said. He couldn't be certain in his stupor. In truth, it could have been anything, but he appreciated her voice anyway. It reminded him that this was real, yet sent him even deeper. Bizarrely, his entire sex life seemed to flash before his eyes. From his first fumbling experiments with masturbation to the awkward birds-and-the-bees talk from his father, all the way through his relationship with Cadance and up to this very day. Twilight was giving him the best orgasm of his life - by a long margin - and he didn't want it to end, let alone go back to regular masturbation. In his head, that was like comparing cheap firecrackers to a royal fireworks display.
* * *
Twilight watched her brother, enrapt. His impressive cock continued twitching dryly under her spell. His mane was unfurled carelessly on the pillow as he shuddered. The strong, well-toned muscles on his flanks showed nicely each time he tensed up. He was just so...male! She was feeling quite warm with the sheer eroticism of it. Not made of stone, Twilight had a terrible urge to reach down and take care of her own needs. More than once, she nearly did, but in the end, her hooves stayed on the edge of the bed. There would be plenty of time for that later. Right now, Shining Armor's pleasure was paramount. Considering the scene playing out before her, she realized she must have the restraint and patience of Celestia herself to remain focused during all this. She rewarded herself with a figurative pat on the back. Being able to give Shining this gift was making her very proud.
* * *
As he lay there in his own mess among the towels, eyes screwed shut, Shining began to wonder how long he could take this. There was, after all, nothing he could do about it. Twilight was in control. He groaned weakly as the electrifying feeling worked him over. It was so good, Shining didn't know how to deal with it. He knew her special talent was magic, but this was truly unique!
"Okay, mister. You need a rest." When Twilight finally began to pull back and allow her brother to settle, he was disappointed, yet strangely satisfied. Like waking up from a pleasant dream after a good night's rest. She brought him out of it very gently, allowing his body to calm itself and readjust to the absence of her magic. The pulsing in his groin eventually came to a stop. The wondrous feeling left him, and his senses returned as the last of her horn's glow dissipated.
Silence filled the room. Shining sank into the bed. He blinked a few times, looking up at his sister. "Already?" he said, slightly out of breath.
"It's been about half an hour."
Did he hear that correctly? "What?!"
"Seriously. Look," she said, pointing to his clock.
He followed her hoof to the opposite wall. Indeed, it was well after eight. Shining couldn’t believe it. It certainly didn't feel like thirty minutes. Not even half that! What a spell!
"Besides, my magic needs a break."
No words could possibly express it, but that didn't stop Shining from trying. "Twily...that was...incredible," he said with a shiver of foggy pleasure in his voice.
"I know," she said, not without a hint of pride. "Believe me, I know."
Both ponies watched Shining's penis shrink back into his sheath and disappear. After swatting away thoughts of his sister undergoing the same spell, he put a weary hoof on hers. "Sis, you gotta teach me. Please?"
Such a smug look she wore now, he was worried her smile would come right off her face. "Alright, I promise I'll teach you later, but you should clean up first."
Shining looked down his body. She was right. He was an absolute mess. The whole extent of his fluid supply had been expelled in that orgasm, and he was now dripping with it. All the way up to his neck were streaks and globs that ran off his torso in little rivers. It was impressive in a weird sort of way. He was certainly thankful for the towels now. He took some of the ones that had gone unsoiled and wiped away what he could; just enough to allow him a trip to the shower.
He stepped off the bed and onto shaky hooves. "This is officially the weirdest day of my life." With a little effort, he made it to his bedroom door, where he and Twilight exchanged sincere smiles. "But it was really fun. Thanks, Twily."
"You're welcome, BBBFF."
