Even bundled up from head to toe and with her arms wrapped around her brother’s waist, Twilight Sparkle’s teeth chattered violently in the freezing winds, to the point that she barely noticed when the snowmobile powered down and Shining Armor started pulling her up. It took a bit of work to pry her out of the seat, but soon (after Shining fished a tarp out from under the snow with his magic and haphazardly threw it over the snowmobile), they were stumbling towards the warm glow from the window of a snow-covered log cabin. As soon as they got close, cyan magic threw the door open, yanked them inside, and slammed it shut behind them. Twilight nearly cried as the biting cold around her eyes began to melt away, surrounded by warm air and the warmer embrace of two beloved family members.

After a moment, Cadance spoke up. “Oh, goodness, what took you two so long?”

Shining answered, to Twilight’s gratitude—even bundled in his jacket, she couldn’t trust herself to speak through her chattering teeth. “Her train was delayed, and she wasn’t prepared for just how cold it would get this late.”

“Twilight? Not prepared?” Cadance’s voice took a joking tone as her hands framed Twilight’s face. “Are you sure you didn’t actually pick up a changeling?” Both siblings just gave her a look, even as Twilight was still shivering. “What? Too soon?”

“You were the one who got kidnapped,” Shining pointed out.

“And you got brainwashed so hard you couldn’t see straight,” she shrugged. “The way I see it, the sooner we can joke about it, the easier it will be to put that nastiness behind us. But that reminds me…” She pulled away from the cuddle and crouched to her sister-in-law’s eye level.

“Sunshine, sunshine, ladybugs awake!” Twilight picked up the chant and motions halfway through the first line, despite her shivering. “Clap your hands and do a little shake!” As they turned to shake their butts at each other, Shining’s grip on Twilight’s shoulders kept her steady. With a shared laugh, the three rejoined their hug.

Shortly after, the siblings discarded their luggage and slushy outerwear, and all three were seated in the living room in front of a cracking fireplace. The newlyweds arranged a fortress’s worth of cushions around them to ensure Twilight was squeezed snugly in between them. With a blanket over her back, her family at her sides, and hot cocoa in her belly, Twilight was finally capable of speaking clearly. “I think Ponyville made me forget how cold and windy mountains could get, especially at night,” she was explaining, clutching her mug. “I was concerned when the train was delayed, but I remembered a self-heating spell I picked up once for an exam.”

“Are you talking about Sunbeam Song’s Heat Regulator?” Cadance asked. “It sounds like you forgot it doesn’t hold well in heavy winds.”

Twilight blushed, but Shining leaned in to whisper, “don’t let that get you down. Cadance only knows that because she made the same mistake, once.”

Cadance smacked him playfully. “Hey! Don’t take away from my ‘wise older sister’ act!”

Twilight just giggled at this display. “Well, even after freezing my butt off, I’m still glad to be here with you two.”

“Awww, so are we!” They all shared another hug. “Though it might’ve been better if you joined us in the Bahaymas,” Cadance mused. “We had an over-water bungalow there, and it was just lovely!”

“Yeah, what’s with that?” Twilight asked. “Going straight from tropical islands to a snowy mountaintop? That seems like quite the leap.”

“It was actually Auntie Celestia’s idea. We actually wanted to spend our entire honeymoon up here, but she suggested we spend our vacation somewhere a lot warmer.”

“She was oddly insistent on that,” Shining Armor added, rubbing his chin in thought. “Like we wouldn’t get another chance for a while.”

“Huh. That sounds… ominous.”

“I wouldn’t worry about it,” Cadance shrugged. “But anyways, we compromised. We spent almost two weeks in the tropics, mostly at the bungalow. Oh, and on the way here, we stopped in Las Pegasus for all the rides!”

“Oh?” Twilight smirked. “And how many times did Shiny throw up?”

“Twilight!” he cried, mortified.

“Oh, only once,” Cadance giggled. “I’m so proud of him!”

“Cadance…” he groaned as both women laughed at him.

“He may be a big, strong, Royal Guard Captain,” Twilight said, nuzzling his chest, “but he definitely got Dad’s stomach instead of Mom’s.”

Cadance leaned over to join in on the nuzzling. “I can think of at least one other thing he got from your dad.”

There was a pause as the siblings tried to parse her meaning, furrowing their brows. Cadance eventually clarified, “I’m talking about his dick.”

Shining just groaned while Twilight shot her a disturbed look. “Why…?”

“Cadance… spends time with Dad every now and then,” he explained, pinching the bridge of his nose

“What? Since when?”

“I started fucking him back when I was babysitting you. Your mom, too. Oh, come off it, you two,” Cadance tutted at their outraged sputtering. “Is it any surprise I think the parents of two of the sexiest people I know are sexy too?”

“…But— they’re our parents!” Twilight squeaked.

“They’re your sexy and very eager parents! Now stop pretending neither of you have gotten off thinking about either of them.” She tapped her forehead. “Princess of Love, remember? I know these things.”

Wordlessly flapping their jaws, the siblings turned to each other. After a moment, they silently came to an agreement and sighed in resignation. “Yeah, they are pretty sexy,” Twilight admitted.

“Mhm,” Shining grunted, sagging into the cushions. “Mom’s got a great rack.”

“I knooow,” Twilight groaned. “I hope I got the genes to stay that perky when I’m her age.”

His hand came up around her and groped her chest through her sweater. “I hope so too,” he said as she squeaked in delight.

She retaliated by shimmying into his lap, ass-first, and grinding against him. “While I’m at it, I also hope I got the genes for her ass, and I’m just a really late bloomer,” she sighed.

Shining rolled his eyes and kissed her neck. “Hush.”

Cadance just watched the siblings with a growing smile. “You know what? I hope so too. I do love watching Velvet’s ass jiggle when I go to town on her with my own cock, especially while Nighty’s doing the same to me, and I would love to do that with you two.”

They stopped to stare at her in shock and arousal. “Do you… do that often?” Twilight asked.

“Oh, yes!” she giggled. “Almost as often as they have me in the middle, double stuffing me. And I do like it when Velvet’s tits are mashing against mine, and Nighty’s body grinding against my back.” She reached over to pat her husband’s arm. “Though yours definitely feels better, Honey.”

The siblings hardly noticed, their heads filled with the fascinating mental image. Both of Shining’s hands were now buried under his sister’s sweater, each from a different direction, while she had a hand pressed against the growing bulge of his pants. Cadance’s sensual grin stretched even further. “You know, most kids don’t get off on hearing about their parents’ bedroom exploits.”

They spared a quick glance at each other. “Most couples don’t invite their sister into their honeymoon bed,” Twilight retorted. “We aren’t like most people.”

Shining nodded while Cadance laughed. “True enough. Then I’ll continue.” Hiding another giggle at how the siblings perked up, she thought of a particularly juicy tidbit. “Did you know I like to roleplay as their daughter? Years after I stopped babysitting you, I’d dress up and do my hair like I did back then, and I’d call them mom and dad.” She paused and tilted her head. “Technically, now they really are my mom and dad!” she giggled. “Anyways, it really got them hot. Dad would make me sit in his lap and pose for him, and Mom—did you know Velvet never let herself stop lactating? She would have me drink from her, and mmmmmm, she tasted delicious!”

Both jaws dropped. After a moment, Twilight spun around in Shining’s lap, only waiting long enough for him to untangle his hands from her sweater, and began pulling blankets and clothes out of the way, him quickly joining. “Fuck, I can’t even wait,” she groaned as her brother bared and squeezed her breasts. “Dad’s got a dick like you, Mom’s got natural milk, and they’re into incest roleplay? What the hell are we waiting for?”

“Roleplay and reality are different things,” he sighed as his hard cock popped free of his boxers into his sister’s grip. “After all, Cadance likes to roleplay as a kid for me, and it’s… different, but I wouldn’t dream of actually going after one.”

Twilight froze. “Seriously? She got you into that too?”

“A little, but she gets off on it a lot more than me,” he sighed. Twilight gave her sister-in-law another disturbed look.

“Hey, don’t knock it until you try it!” she chirped.

“…Yeah, I don’t think I will,” Twilight deadpanned. Cadance just pouted.

Shining Armor decided to take his sister’s mind off the topic by wrapping his arms around her body, pulling her up against his, and wrapping his lips around one of her rock-hard nipples. She squealed, holding his head in her hands and pressing his face harder into her chest. “Oh, Shiny, you know me so well,” she moaned. “In fact, I think you deserve a reward for being such a good brother, and Cadance has given me a fantastic idea for one.” She snapped her fingers.

After a few seconds, he started to moan in appreciation as a stream of warm, creamy milk started to pour down his throat. Cadance, watching giddily, couldn’t sit still any longer. She scooched over to her husband’s side and leaned in to lick up the trail of milk dripping from Twilight’s free nipple before claiming it herself. Twilight cried out, curling a hand behind the new head and basking in the blissful sensations of both her beloved bigger siblings drinking deeply from her, each tongue expertly teasing her teats, each stroking her breasts with a hand, and each mouth constantly drawing out the sweet, nourishing liquid from within her.

The spell didn’t last for long, however. In only minutes, Twilight was drained dry, and the couple reluctantly let her go with a deep, final suck each, stretching out her tits before letting them pop back into shape. While she panted, they turned to each other and locked lips, sharing the last of her milk. Soon, Cadance pulled her head down, and Twilight squealed as her lips joined theirs, dribbling sweet milk in a three-way kiss with two of the most precious people in her life. All three of them had plenty of experience in kissing, but Twilight, overwhelmed by the sensuality and Cadance’s magic still playing with her, was utterly outmatched as both her partners dominated her mouth, hardly giving her a chance to breath.

When they finally parted, Twilight’s chest was heaving, but that hardly slowed Cadance down. With a snap of her fingers, every scrap of clothing had disappeared from the trio, and the couple stood up. Twilight shivered as Cadance’s magic faded and she was left alone on the couch—while the cabin’s thick wood and enchantments kept the bitter cold out and the gentle warmth of the fire in, she missed the contact of other bodies. Before she could complain, however, Cadance snapped her fingers again, causing a pink, crystalline strap-on to appear around her hips. Twilight eyed it appreciatively, but her eyebrows rose when Cadance casted another spell. “Not an illusion?” she asked.

Cadance huffed. “Of course, not an illusion! You can’t get creative with just that!” She thrust her hips forwards, jutting out her new cock which—while still looking like it was roughly carved from pink crystal—melded with her crotch seamlessly and bounced like flesh. “Really, Twilight, when’s the last time you’ve tried a transformation?”

She tilted her head. “Well, besides Celestia, it would be… I dunno, almost two years ago. I never really saw enough of a benefit to switch from the illusion.”

“Not enough benefit? I don’t believe you. Besides, you’re the best spellcaster of your generation! The switch should be trivial for you.”

She just shrugged, chewing on her cheek. “Well, as a pet project, I have been reverse-engineering Princess Luna’s flesh-shaping magic,” she offered.

Cadance’s eyes lit up. “See? Now there’s something interesting! Let’s see it!”

“No.”

“What?” she cried. “You can't just bring that up and not show me! Come on, pleeeease?”

“I said no!” she barked. “It’s nowhere near complete enough that I can confidently cast it without risking having to rush someone to a hospital in order to avoid permanent scarring or a crippling disability, at which point I would have to explain that I’ve been experimenting with barred magic I’ve only seen used by a Princess. All-in-all, it would likely utterly ruin your honeymoon.”

Cadance was about to respond when Shining Armor grabbed her hips and effortlessly thrust his hard cock right inside her wet, ready pussy. “You two are spending an awful lot of time talking about sex spells instead of having sex,” he teased over her squeak.

After catching her breath, she giggled, “Sorry, Honey! You know I can’t help thinking about new ways to play.” After a quick nuzzle, the couple maneuvered Cadance’s crystalline cock over to Twilight, who spread her legs out eagerly. Cadance’s tip prodded Twilight’s dripping lower lips before quickly sinking in, and she sighed at the feeling of her first time in her sister-in-law’s pussy. Twilight, meanwhile, took in the unfamiliar sensations. She had experimented with crystal before, finding the smooth surfaces and hard, geometric edges an interesting novelty, but feeling it warm and throbbing in her was a very different experience. Cadance interrupted her thoughts by bending over and gently pressing their lips together, still hilted in her.

Soon, Shining slowly slid out of Cadance, and she followed, sliding out of Twilight while filling herself back up with Shining. They settled into an easy, languid pace, gradually crawling up the sofa and rearranging cushions so none of them had to strain, lying on their sides to grind their hips together. Their hands danced everywhere, curling around each other’s fingers as often as they stroked and groped sensitive flesh. Cadance and Twilight shared a slow, tongue-filled kiss until Shining leaned over his wife’s shoulder, at which point they each took turns kissing each other, at least whenever all their lips weren’t mashed together. Minutes passed like this, and while Twilight wasn’t quite sure why they were fucking at such a sleepy pace, but she wasn’t going to complain—they had plenty of time to spend together.

Maybe half an hour later, Twilight finally felt a change in pace as Cadance’s movements sped up and she started audibly panting. It looked like being in the center of the siblings’ love-making really heated her up. Mid-kiss with Cadance, she locked eyes with Shining Armor, and they silently plotted with each other, smirking deviously.

Suddenly, Twilight broke the kiss, and the siblings rolled around so that Shining was hunched over his wife while Twilight cuddled her from below. Cadance barely had time to gasp before her husband started driving into her with longer, faster, but still smooth strokes while her sister-in-law rhythmically slammed her sex on her transformed cock. Both of them wrapped their arms around her, stroking her skin and tugging her breasts, and they each bent over to suckle at either side of her neck.

Their plan went off perfectly, catapulting Cadance from her gentle plateau of pleasure to a peak of blinding ecstasy. Neither sibling let go as she shook in their combined grip, still smoothly fucking as she spasmed around Shining and throbbed and unloaded inside Twilight. Only when her cries and thrashing died down did they finally slow down, pulling their mouths from her neck, leaving mismatched marks.

Seeing that she was too insensate to do much more than moan, they both pecked her mouth and pulled her away, glittery semen dribbling from her crystal cock as she popped out of Twilight. Gently, they set her aside as well as they could manage on the crowded sofa before finally facing each other. They wasted no time or words, Shining Armor aiming his slick cock at his little sister’s already creamy pussy and stuffing it, just the way he knew she liked it. She squealed, pulling his head down for a deep, passionate kiss as he got right to pounding her, their appetite for slow sex exhausted for now.

When Shining finally broke their kiss, he leaned on his elbows so he could palm Twilight’s tits. “So, what’s this I hear about Luna and flesh-crafting?” he asked, not slowing his pounding in the slightest.

“Flesh-shaping,” she corrected, her words only slightly affected by their fucking. “And I thought you’d rather have sex than talk about sex spells,” she teased.

“We’re having sex now,” he pointed out. “We can multi-task.”

Twilight giggled, grinding against his pelvis as it crashed against hers. “It’s what it sounds like. Flesh-shapers could almost freely transform the bodies of themselves and others, like giving soldiers tougher skin and muscles, or, you know, giving a girl a huge rack and dick. As you might imagine, it also had far less pleasant uses, and even benign, temporary changes could have nasty long-term side effects, to say nothing of—Ah!”

He cut her off by pinching her nipples. “I get the gist of it; I already took an entire course on criminal magic and its history,” he sighed. “I was asking more about Princess Luna being a flesh-shaper.”

“Oh, um, well, Princess Luna is a flesh-shaper,” Twilight shrugged. “I guess she had time to master it long before it was barred. Apparently, back then, they used flesh-shaping for sex spells instead of illusions or temporary transformations. She used it to give me a huge, really sensitive dick for a… contest between her and Princess Celestia.”

“Whoa, both of them?” he whistled. “Way to go, Twiley! But a contest? Who won?”

Twilight smirked. “Well, I guess I’d have to say incest won.”

He stopped thrusting at that. He stared for a second, then burst out laughing. “The princesses joined the incest club? Oh, man, that’s just great. I mean, that’s both hilarious, awesome, and sexy!” He quickly shuffled, slightly bending her hips so he could start fucking her even faster and harder. “I’ve got to hear more about that!”

Twilight opened her mouth to oblige, but was interrupted when Cadance sat on her face. “Sorry, Honey,” she giggled over Twilight’s muffled cries, “but I want a turn with her mouth.” Her crystalline cock bobbed in the air, the cum-coating glittering in the firelight. “But maybe I can tell you about me and my Aunties?”

He raised his eyebrows, still plowing his thrashing sister. “Aunties? As in plural? So you’ve been with Luna, too? Why is this the first I’m hearing about it?”

Cadance giggled, leaning over to smooch her husband. “Think of it as punishment for never telling me about you and Twiley here yourself.” By now, Twilight had stopped struggling and resigned herself to her fate of eating out her babysitter. “I’m sure you’ve noticed that both Auntie Celestia and Luna got more amorous after last Nightmare Night. That’s when Twilight got them to realize their long-ignored lust for each other and also repeal some stupid ancient law about princesses’ lovers being exclusive from other princesses, which, by the way, I’m pretty sure is the reason she never called you up. Since then, they’ve both gotten a lot friskier with me: I finally got an orgy with Celestia, and wow, can she handle a lot of cocks at once!”

“Mm-hmm!” Twilight agreed eagerly from under them.

“Luna, meanwhile, was always… distant. If I didn’t know any better, I would’ve thought she wasn’t interested in anyone at all! In retrospect, she was just being shy and guilty and didn’t want to step on Celestia’s toes by risking going after someone who was already ‘claimed’.”

Twilight grumbled something, but quietly enough that the couple ignored her.

“When she got over that, well, Luna got direct. She didn’t so much proposition me as she personally dragged me into her bedroom, threw me to my knees, and demanded I demonstrate my reputed ‘oral mastery’ for her.”

“Which kind of oral mastery? Pussy or dick?”

Cadance smirked. “Both. A lot.”

At this point, Shining Armor’s thunderous pace finally stopped, his hips slamming against Twilight’s one last time. Twilight squealed into Cadance’s pussy and locked her legs around her brother as his rod pulsed inside her, pumping his love into her and mixing it with his wife’s. When he was done, they sagged together in contentment

Eventually, the couple both pulled away from Twilight, though Cadance didn’t pass up the opportunity to lick up the glittery mess from the siblings, kneeling on the ground to reach them.

“So,” Shining Armor said after Cadance moved on from his softening cock, “who’s hungry?”

“Me,” Twilight exclaimed/panted, raising a tired hand into the air.

The princess just made a noise of disappointment into Twilight’s pussy. “What, already? Just like that?” she cried once she finished. “We each only came once! And I have plans! Twilight will never bother with the illusion spell again when I’m through with her!”

“I don’t doubt it, but we have plenty of time for that,” he said, walking away from the couch without bothering to dress. “But right now, I am hungry, and I am checking the crockpot. Between Twilight’s train being late, and how long we’ve been at it, I’m worried…”

Cadance sighed as she watched her husband walk into the open kitchen. Then a finger tapped her soldier. As she looked over, Twilight grabbed her chin and pulled their lips together. Though surprised, she let herself relax into her sister-in-law’s slow, wet kiss, enjoying the cocktail of flavors from all of them.

"He's right, you know," Twilight stated after they finally pulled away. "We've got plenty of time to fuck and talk about fucking all we want. No need to rush it."

"I know", Cadance sighed, pulling her closer so they were touching foreheads and staring into each others' eyes. "I'm just so excited to spend quality time with both my favorite people like this!"

Twilight smiled back warmly, but suddenly, the smile stiffened.

"What? Are we not your favorite people?" Cadance pouted.

"I'm… not sure?" She pulled away, tapping her chin. "I mean, you two really do mean a lot to me, but... when you said favorite people, I actually thought about my friends in Ponyville." She was met with silence. "Not that you aren't—!" She cut her panicked backpedaling off on seeing her babysitter's expression.

Cadance was mashing her hands into her cheeks, stars in her eyes, and her grin splitting her face. "Awwwww! That's so precious!"

"Cadance."

"My little ladybug has really grown up!"

"Cadance."

"It feels like only yesterday when you'd rather bury yourself in books or work glory holes than talk to people!"

"Cadance."

"Does this mean you're ready to start dating? GASP! What about your friends?"

"That's it. I'm done here."

"I know there's some serious chemistry between you and Rainbow! Also some with Pinkie! And Applejack, although that would get in the way of her and Rarity, but the heart wants what it wants... Twilight? Twilight! Don't you walk away from me, Sparky!"

Author's Note

*Slams chapter on desk* TIME! Got it out by 2019! I'm counting that as a victory!

If you could believe it, I sat on this thing at 95% done for almost a year because I didn't know how I wanted to continue the scene! Then I came up with the idea of not really continuing it. I tell you, it's hard thinking up new ways to write about people having sex.

Well, the show's literally over, so the goalposts of pornifying the whole series have stopped moving! *stares into the distance* *pulls out binoculars* Hmm.

Fandom. You disappoint me. Why can't I find an image of Twilight making Fluttershy's :I face from the gala?

Next time on Artifact Title: Spike and Twilight have been fuckbuddies for a while, but Spike feels frustrated at the experience gap between them and how Twilight isn't as into it as he is. So, he channels his frustrations in some productive ways. Sex ensues.
