Dear Twily,
That's really sweet of you, sis, but I'm not sure if now's the right time for an all-Equestria Book Fair run. And I know I said that the last three times, but this is… you know, this really isn't the right time. Cadance wants me to join her in Satle Sadull Arabia(?) This hoofwriting's terrible. I can't even read it. She's in Seattle Aruba right now for the negotiations, and she's super insistent that I hurry up and join her. SUPER insistent, I mean. You know how she gets. I'm sorry. Maybe next time?
Love Shining Armor
Dear Shiny,
That's fine. It's not like this is the fourth time we've tried to schedule something, and it's not like this is the fourth time Cadance has had other plans, and it's not like you're my Big Brother Best Friend Forever, and it's not like you said you would always be there for me if I ever needed you. I don't mind. You probably should go and be there for her. I'm starting to see exactly how she gets.
It's 'Saddle Arabia,' by the way.
Love, Twilight.
Dear Twily,
Great! Thanks, sis. I knew you'd understand.
Love Shining Armor
Twilight shifted silently as she waited for the procession to assemble. She wasn't much in the mood to wait right now, but she'd read plenty of the Crystal Empire's customs, and knew the importance of respecting them. Royalty couldn't just walk into the Crystal Throne Room. You had to have a procession, complete with dancers and drummers and — what else? — flugelhorns.
It was a fascinating culture, honestly. She'd have to study it in-depth sometime, when she was safely out of heat. It wasn't that distracting, but the equine biology had its ways. The need to mate crept like a shadow at the back of her mind, making her that extra bit more sensitive. Making things look that extra bit more phallic.
Her eye caught on the blunt end of a Crystal Guard's spear and her mouth felt that little bit dryer. A hoof wandered slowly downward… No. She stopped just in time. Heat or no, it probably wouldn't look good to the Crystal Empire for an Equestrian princess to masturbate in public.
Later, though…
"Princess Twilight!" a guard called. "The procession is ready. Do you wish us to proceed?"
"Of course," Twilight said, nodding. "Let's go."
The throne room's door opened up in a blazing array of trumpets and flugelhorns. A dozen crystal dancers flew in with perfect form, followed by a herald to make the announcement proper.
"Hear ye, hear ye!" shouted the herald, as Twilight stepped forth. "Princess Twilight Sparkle of Equestria, here unannounced for business with Prince Shining Armor."
Shiny's face was priceless. Jaw, meet floor.
"T-Twily!" he said, rubbing his eyes. He shook his head. "What? I thought we were — you know, you said in your letter — I don't… What?"
"I said I was fine with it," Twilight said, stopping just before the throne. "And I am, obviously. I'm just here to see you off, since you'll be leaving for Saddle Arabia tomorrow." She bit her lip. "With Cadance."
"Uh, oh yeah!" Shining Armor said, his eyes brightening. Storm cleared. He stood and ran to hug her, wrapping Twilight in a warm, brotherly embrace. "Glad you came, then, sis."
"Mmm." Twilight returned the hug with gusto. He smelled of sandalwood and cinnamon and all the other scents the Crystal Empire thought royal. Perfect for a stallion like him. She took a deep breath, nuzzling her muzzle into his thick, strong neck. Yep, that was Shiny alright.
Just like the old days, nothing like the new days. It occurred to her that they hadn't hugged like this in a long time… Why?
Cadance, of course.
"So..." Shiny started, breaking the hug (too soon!). "I was actually planning to wrap up with the court for the day. Do you want to, you know, stay the night and see me off in the morning?"
"I'd love to," Twilight said, waiting just a second longer to step back. She paused and took a moment to collect her thoughts. Deep breath. Now or never. "Can I… Can I keep my quarters with you?" She tapped her hooves awkwardly. "Since, well, Cadance isn't here right now…"
"Sure!" Oh, Shiny. Always happy to please. Always ready to do anything for her, so long as Cadance didn't have other plans. "You can room with me! It'll be just like that one time you were too afraid of the thunder to read about it, and you asked if you could—"
She coughed.
"Right, right, sorry. Old habits and stuff." He looked toward the rest of the procession and clapped his hooves. "Alright, gang, show's over. You can take the rest of the day off. Guards too."
Every mare and stallion gave a gracious bow and trotted off, leaving Twilight and her big brother — alone — together in the throne room.
"Show you to your room?" Shiny offered, holding out a hoof.
"Our room," Twilight said. She gave him a mock bow, just like in the old days. When she'd played princess and he her daring knight. "Lead the way, Captain."
Shiny cocked his head, vaguely puzzled for a moment — then he grinned and returned the bow. He remembered! He always remembered the important things, when it came down to it. "It would be my pleasure, Princess."
She tried to keep her eyes off him as they walked together down the corridor, but somehow or another she couldn't. All the fascinating architecture and interesting artifacts of the Crystal Palace couldn't compare at that moment to her older brother. His confident strut, his muscular flank, the slow, sensual movement of his tail as he…
Half of it was the heat, obviously, but another half of her couldn't help but wonder. Objectively — objectively — Shining Armor was an incredible catch. A well-built captain of the Royal Guard, who also happened to be the best older brother in the world? Cadance wasn't by any means a bad fit, sure, but maybe, just maybe, Shiny could have done just a teensy bit better.
His tail swished to the side again, revealing just the slightest glimpse of Shining Armor's tantalizing package, his balls bobbing gently between his legs. Gifted there, too, of course, but not a talent he'd bothered to ever show her. Oh, if only. She could almost feel herself slickening at the thought…
But no, she had to hold it. Not here, not now, not yet. Not yet.
"And here's the room!" he said, opening the door for her like the perfect gentlecolt he was. A faint whiff of rose petals drafted out from the crack. He shrugged, almost embarrassed. "It's not that much."
"For certain definitions of 'much,'" Twilight murmured. The room was a little snug, fair enough. A dresser, a nightstand, and not much elbow room, but that was more than made up for by the massive bed dominating the center. The finest silk sheets, phoenix down pillows, the works. Magic mood lighting, even! She dimmed the lights to a faint violet and bit her lip, imagining what else she could do with it... What Cadance had undoubtedly done with it. She huffed as the fantasy fell to pieces. Oh, why did Cadance have this room and Shiny all to herself? It just wasn't fair!
...But it would be soon.
"That's about it," Shining said, following her in. "I was thinking we could get your things up here quick, then go grab a bite to eat after that? Hope you're hungry, sis." He licked his lips. "The head chef here makes the best hayburgers."
"That sounds great," Twilight said, licking her lips for altogether different reasons. "I'd love eating out."
She knew he wouldn't catch the double entendre, but that was half of why she loved him.
"Great!" he grinned. "So, I'll just—"
"Oops!" she accidentally purposefully knocked a picture to the floor. Shining and Cadance at the wedding. "Oh, I'm so sorry!" She leaned down, way down, to grab it with her hooves. "Let me just get that..."
"It's no big deal, sis," he said, trotting over. "We've got a hundred pictures like that. Even if you broke it, I'm sure—" He stopped as she wiggled her generous flank straight in his face, her tail parting just an inch to display her most precious parts. His eyes only. "Uh, Twili..." She could almost hear him sweating. "You know... You know you could get that with magic, don't you?"
"Don't be silly!" Twilight said. She knocked the picture frame a little further away, forcing her to lean a little further down. She could only imagine the view Shiny was getting. "I've almost got it!"
"If you say so..." Shining coughed. She almost had him. Twilight gave her rear another wiggle, shifting her pleasantly hefty, oh-so-squeezable cheeks. Her soaking lips gave him a wink, inviting him inside. She could practically smell her own arousal from a body-length away, so she could only imagine what Shiny was getting. "Right..."
It wasn't even difficult to tease him like this. She'd read all his magazines; she knew exactly what he liked, and if he'd ever read her magazines, Shiny would have known that he was exactly what she liked. She was his, if he wanted her. All he had to do was reach out and take it... "Uh, Twili!" he panted. "C-come on! We don't have all night, you know."
Oh, but Shiny was too much of a gentlecolt for that. He was miserable at hiding how much his little sister had grown on him — how he'd finally noticed her ascension from a modest bookworm to an alicorn goddess — but he was too honorable to make the first move.
That was fine. She could make it for him. The picture came up and she placed it face-down on the dresser. She turned slowly back toward him, loving the desperation with which he tried to hide his raging erection. A foot long, if an inch. The faintest hints of a smile played at her lips, but instead she gasped in mock surprise. "Shiny!" she cried. "Oh my goodness! Is that — were you — were you staring?"
"N-no! Of course not!" But the protest was weak. Half-hearted. He didn't really think he could get away with lying to his little sister, did he?
"It's okay, Shiny," she said softly, running a hoof down his chest. "I understand. I'm in heat right now. I'm probably giving off all of these pheromones. Things that make big, hunky stallions like you go wild. And this flank!" She looked to her tush and gave it another shake, fully aware that every ripple in her cheeks sent another heartbeat's worth of blood straight to Shining Armor's cock. "It just keeps getting bigger! Too many days sitting in the library, eating sweets. I'm not sure if I can afford to eat those hayburgers." She backed slowly up to him. "Do you think it's too big for hayburgers, Shiny?"
"Ah, n-n-buh!" he stammered. She decided she could afford a giggle out loud. Her big brother's brain clearly needed a reboot. "No, no! Not at all! You look great, Twily!"
"It's so sweet of you to say that!" She sighed. It really was a pleasure, hearing that last, verbal confirmation. He wanted her. She wanted him. She'd gone without him four times this year, and she wasn't going to let him get away now. "Say, Shiny," she began, in her sweetest little puppy-dog voice. He'd never been able to resist that. Not once. "I have an idea. I could use some... relief right now, and I can see you do, too. Why don't we fool around a little before dinner?"
That woke him up. She could swear he'd actually jumped. "What?" He laughed nervously. "Y-you're joking, right? Look, Twilight, I love jokes, but—"
"But, of course, you love me more," Twilight finished for him. She pushed her rump up until her desperately needy nethers could stare him in the eye. She could almost feel his shallow breaths against her sensitive lips, the long, slow line of sexual drool dripping down. The puppy-dog voice came on a little thicker. "Come on, Shiny. We're both in the mood. What's the harm?"
"The harm!" he choked out, backing away from her. "I've — sure, I've thought about it, I guess, but... And you're really hot, Twilight, but..." He coughed, trying to catch a pause. "Well, for one, we're brother and sister!"
"Contraceptive spells," she said immediately, turning around to face him. She'd gone over this moment. She knew the lines. "Five of them, already cast."
"But, but the law!"
"I'm a princess of Equestria, and you're a Crystal Prince." She giggled. "We are the law."
"Cadance!"
"Cadance..." she whispered. She leaned in close, very close. Close enough to smell his cologne, his sweat, his need. "Doesn't have to know." She leaned away and winked at him, with her eye this time. "And besides, you owe me at least three favors after canceling our other plans. I have the letters to prove it."
"Well..." She could almost hear the gears turning in his head. A solid minute of careful consideration. Finally, he sighed a defeated sigh. "Alright. If it's quick."
She didn't need to hear any more. They were on the bed in the blink of an eye, with assistance from a blink of magic. Her on top, him on the bottom. Finally, face to face — and quite a bit more than that down below. For a moment she could only stare into his big, steel-blue eyes, and he could only stare back into hers.
"Sis..." He broke the silence first. "You're pretty hot."
Oh, to finally hear that. Her heart fluttered in her chest. She giggled and turned around, the bed springs easily handling her weight. Her rump planted itself just before his face as she settled herself down by his thick, twitching cock. "Your princess is in need," she practically sang. "Would her knight in shining armor care to help?"
He did care. He cared a lot. She could hardly stifle her gasps and whimpers as Shining's tongue met her steaming-hot slit. Jolts of pleasure ran up her spine with his every move. Long, purposeful licks up her lips, mixed with delightfully squirmy forays deeper in. Best of all were the fleeting, teasing passes over her throbbing clit. "Ffffuck!" she screamed, her restraint dropping in an instant. "That! Keep doing that!" He was so good at this! He had to have experience. Cadance, no doubt. Warming him up for the main event.
"Okay, my turn." It was time to give back, to show him just how much she could do for him. Cadance may have been a princess of love, but Twilight Sparkle knew her big brother better than any pony in Equestria. And she'd prove it. It all started with his dick, a foot-long black obelisk that twitched and pulsed as her warm breath fell on it. She hadn't had all that many sexual partners before Shiny, but she knew it could overshadow pretty much any stallion's, easily. It was Shining Armor's, cock of cocks. Look on its length, ye mighty, and despair.
She started with a slow lick up the shaft, followed by a line of sloppy kisses, from his heaving balls to the meaty, flaring tip. She sighed as Shining gave an approving moan, which reverberated straight into her core. Clearly, she was doing something right. She swallowed the tip easily, licking and sucking with gusto. The first drops of salty pre were beading upward, and she lapped at those with special care. Her horn glowed as she caressed his swollen sack in a light magical massage, just like stallions liked.
"Ooooh," Shining Armor moaned. "She never does that."
Anything for him. Finally, she took it wholesale, stuffing as much pulsing meat down her throat as she could manage. Bob up, bob down, just as it said in the book. He seemed to like it, lapping at her cunt with redoubled enthusiasm while growing trickles of precum ran down her throat. Now and then she did have to come up for air. Deep-throating her brother, satisfying as it was, made it a teensy bit difficult to breathe. Sacrifices, sacrifices.
"Guh!" That last lick against her clit. That was just too much. She couldn't take any more teasing, and from the twitches that ran up Shining Armor's shaft, he wouldn't take all that more either. She stood up and presented herself to him in all her needy glory. "Now!" she gasped. Articulation was for ponies with attention to spare. All she could think about now was getting filled up.
And Shining delivered. With a grunt, he rose to his hooves and mounted her, the springs creaking and groaning with their combined weight. "Ready, Sis?"
She'd been ready for years. She was hot, she was wet, and she needed him "Now!"
Words couldn't describe what she felt when that flaring tip plunged into her. Amazing was a start. Mind-blowing got a little closer. She eeped slightly when his cock — overwhelming — delved too deep, but he quickly found how much she could take, and settled into a steady rhythm. Or as steady as it got. Heart-stopping, earth-quaking thrusts straight inside her, punctuated by tantalizing retreats. "Yes... mm, yes, yes! Yes, yes, yes, yes, yes! Faster!"
Squelch, schlick, squelch. His balls slapped wetly against her with every thrust. So good. So very good. Sweat ran down her coat in streams, and breath came in short, huffy gasps. She'd never felt so satisfyingly full in her life. She'd had dildos about as big, or maybe a teensy bit smaller, but none of them had been attached to Shining Armor. None of them could give her exactly what she needed from them — not like he could. Not like she'd always wanted. He was giving her all he had, and she was milking him for all he was worth, tensing and squeezing around him in time with his thrusts.
The tempo sped up. Faster and faster, harder and harder, deeper and deeper, until...
"Ngh, oh, Twi — Twi — Twilight!" Every part of him tensed as he screamed, and that was her name he was screaming. She barely had a moment to savor that as he erupted, filling her completely with warm, sticky cum, and turning her vision white to match her insides.
And still, ever the gentlecolt, he kept thrusting, his softening cock sliding and spreading his piping-hot semen against her walls. The mere thought of him, still so desperate to please her, trying his hardest to fulfill that deepest, most intimate bond between siblings, thinking only of her in his most private fantasies... That was more than enough to send her over the edge. "Ah!" Her pussy squeezed tight and a deep, all-consuming warmth rose up from her hooves to her horn. Her screams weren't nearly as coherent as his were, but they were louder, and she meant just as much by them. Nothing else mattered but this. Twilight Sparkle, Shining Armor, and the mind-blowing orgasm he'd just given her.
Quietly, he dismounted, and they both slumped to the covers. Both of them in each others' hooves, just like old times — if they'd been covered in sweat and other, stickier fluids back then.
"Oh, Shiny," she whispered, burying her muzzle in his chest. "Promise we'll do this again, soon?"
"I..." he was still breathing hard, but she could tell she'd won. He was her Big Brother, Best Friend Forever. And now Best Fuck Forever. Cadance, for all her wiles, couldn't love him like that. Couldn't give him what she could. And he knew it. "I... think I'll write and tell Cadance I have to cancel. We... I think we need to spend some more time together."
"Mmm, thanks, Big Brother," she whispered, giving him a peck on the cheek. She grinned and snuggled up, wrapping one hoof around her knight in shining armor. The other was buried deep beneath the covers, stroking and teasing her engorged cunt as it waited patiently for round two. "You're the best."
