Twilight Sparkle, nerd of epic proportions, Princess, Element of Magic. All these things described her, but none of them were what she really was.

Sister, lover, hornier than a herd of unicorns? Yeah those fit.

Will it even fit?!? She couldn't help but wonder as she stared at the titanic slab of stallionhood in her hands. Ten inches long and at least three across at the base. Sure, Celly and Luna had dildos but...seeing one in person, a real one, the only one she'd ever really wanted. Well it was intimidating.

Seeing her hesitation "You okay Twily?" Shining asked.

"Y-yeah, just.. never seen a real one before." She replied, now nervous for some reason, even as the incessant Heat made a furnace of the cleft between her thighs. She was quite certain she was going to have to replace the sheets after today, she just wasn't expecting 'pussy shaped burn mark' to be why.

"It's okay Twilight, you don't have to rush things. Come up here, let's start slow." Shiny said as he pulled her up face to face. He leaned in and let their lips meet for the first time. A slow soft kiss that deepens into open mouths, wrestling tongues, and breathless sighs as the heat reasserts itself, overpowering her nerves.

But now Shiny took the reigns and rolled her onto her back, taking care to settle her wings comfortably. Looking into the eyes of his little sister he realized that while this might be new for him, she's wanted this for years. The least he could do is make it worthwhile. Kissing and nibbling his way down her neck to the slopes of her breasts he realized, perhaps for the first time conciously, that she had a beautiful set. Firm, gravity defying, with small pink nipples begging to be licked and kissed in equal measure. Although he paid some loving attention to those wonderous globes, his goal was south of the border. A Taco Run if you will.

Moving down her body he finally saw his sisters dripping nethers, slick with moisture and blooming just slightly to show the delicate blush of pink her soft folds hid. Watching her body twitch as his breath wash over her he couldn't help but smile as he inhaled the fragrance wafting from the cleft of her center.

Twilight's breathing seized as he laved his tongue over her in a long slow motion, teasing and tasting at the same time. "huh vanilla and coffee, with just a hint of tangy goodness. Of course she tastes like a latte."

As he smacked his lips, enjoying the flavor of the newly writhing mare beneath him he grinned "Itadakimasu!" As he spread her folds and plunged his tongue into her depths delving as deep as he could, searching for the source of that deliciousness. This had several reactions, Twilight's shoulders heaved up off the bed as she looked at her brother feasting upon her slit with wide eyes. It also revealed a secret of Shiny's, he had a LONG tongue, obscenely long actually, thick and muscular enough to not only directly stroke over the rougher patch amongst the velvety vice that indicated her G spot but to even brush over the entrance to her innermost sanctum.

As Twilight's thighs quivered and clenched around his ears he opened his eyes to meet hers, frenzy showed in his little sisters gaze like a newly formed zealots, he countered it with a look of utter loving compassion. He truly did love her, it just took seeing her memories to show him exactly how he loved her.

"S-shining Armor, I swear on Faust's mane if you don't get up here and stuff me full of enough cock the Roosters union files a grievance!"

Removing his tongue and flicking it fast and hard over her clit silenced the rest of her incoming threat into a shuddering moan, he replied with a smile as his middle and ring fingers slid into her and danced on the old Grafenburg stage.

"You'll do what little sister?" He asked mischievously as she clenched harder on his dancing digits "cum for me? Drown me in this river leaking from you? Don't threaten me with a good time." Pistoning his fingers faster into her slick tunnel he played her like an instrument, the crescendo of moans and squelching wetness was music to his ears as her first climax roared over her like a tsunami, and was twice as wet.

The gush of her juices drenched his face and chest in a blast as her hips levitated off the bed, no mean feat without TK. Shiny just smiled as he slowly flicked his tongue over her clit as she rode out the storm.

With her hips still grinding onto his fingers and smaller spurts of her juices still coming in spasmodic waves she pushed him away only to grab his head and mash her lips to his, tasting herself on his tongue. "H-huh, I taste like a latte. N-nice. Now, please, stuff your cock in me like Spike stuffs gems in his gullet"

"Can we NOT bring your son into this debauchery please?" Shiny replied with a brief look of distaste "incest is one thing but sheesh Twily"

Twilight giggled at her faux pas "True, bad form on my part." Reaching down to grab the steel like pillar of stallion meat tantalizingly close to where she so desperately needed it. Swiping his drooling cock head through the soaked furrow of her cunny she lined him up with her clenching opening "Make love to me Shiny. Please?"

Nodding, he flexed his hips and with only a slight squeeze he entered that clenching velvet vice once again,he was shocked at how well they fit together as he seated his shaft into her heated depths in one slow push "Tight! Faust how are you so tight?"

"It's my first time with a real stallion Shiny." Twilight replied breathlessly, feeling fuller than she ever had.

"Then I'll be gentle." He said with a small grin only to feel Twilight's nails dig into his shoulders as she looked at him with a blush dusting her features.

"Don't you dare! I'm no weeping maiden on her wedding night, I'm an Alicorn. I can take it." Twilight said, fire in her eyes as her Heat started to reassert itself.

Seeing the look in her eyes he steadied himself as he began stroking his length into her spasming tunnel. He was going to take her at her word as soon as he caught his rhythm.

Each of his thrusts was met with one of her own as the sound of wet flesh slapping against each other echoed through the room to the sweet singing of her breathless moans. Each one getting faster and harder until their hips were a blur of impacting flesh.

Shiny felt something coming, something he hadn't felt for a month. "Twily...I'm about to cum little sister." He whispered in her ear as his strokes started to lose their cadence.

"Do it big brother! Fill me up! Break her spell and give me a baby!" Twilight whispered right back, urgent zeal lacing her breathless voice.

With a spark of inspiration and a little magic Shiny flipped them over so that Twilight was on top, gasping as his cock speared even deeper into her, almost bruising her deepest barrier. The slight pain of having her cervix assaulted in such a manner only made it better as she adapted to the new position and began rolling her hips, grinding her clit into the base of Shiny's shaft and the soft tuft of fur above it.

"I want to watch you move, I want to see that beautiful body of yours writhe on my cock as I fill your cunt!" Shiny said, his voice husky from lust as he finally dove headlong into the incestuous deviancy he would enjoy with his sister and now, wife. He could feel his cock head starting to flare for the first time in months as biology took over and his shaft sealed itself to her innermost barrier, the very entrance to her womb.

Grasping her breasts Twilight rode her brothers cock as her aching nipples were picked between her finger. She could feel his cock swelling as his body prepared to fill her womb with an ocean of his cum. Magic flaring from her fingers she let go of all semblance of control and instinctively cast several spells all at once. Fertility boosters, pleasure enhancers for both of them. Arcane sigils flared to life all over the room, ancient symbols of ecstasy and fertility taught to her by Celestia and Luna in preparation for this singular moment.

In a final rush of agonizing pleasure her climax once again crashed over her very soul as she felt his shaft flexing within her core as he filled her womb with his potent seed. A rush of her own nectar flooded the junction of their bodies to the silent scream of pleasure that ripped from her mouth. With a final shuddering moan she collapsed on Shiny's chest.

"Gods that was amazing big brother." She muttered breathlessly, sweat streaking her brow and sticking her bangs to her forehead.

Chuckling tiredly Shiny stroked his little sisters back as he held her, the final pumps of his seed leaving his churning balls as they clenched hard enough to be almost painful.

"Yes it was Twily, yes it was. I love you my little sister, my wife."

Twilight rolled off to lay next to him as she tiredly cast a small barrier spell to hold his seed where it belonged. Another moan rolling out of her as his softening shaft dragged it's girth along her oversensitive walls on its way out.

"So much cum..." She said in wonder as she could feel the puddle sloshing a bit within her.

"Yeah...I think I set a record for creampies with that one.." he said sheepishly as he held her close.

"You'd have to ask Pinkie about that one, hers are pretty big." Twilight said cheekily.

"Yeah, no, I am NOT asking one of your best friends about creampies with me and you being in the equation." Shiny said laughing "The jokes are already non stop."

"She's a baker you oblivious goof" Twilight replied as her magic began to fade from the Castle of Friendship.

"Think it's gonna take this time?" Shiny asked as they retreated from the fantasy they had been playing out.

"I hope so Shiny, I'm the last one that hasn't gotten pregnant yet. Celestia and Luna are both pregnant. Flurry turns eighteen in a few months. I'm hoping to at LEAST be pregnant before Flurry becomes competition." Twilight said with hope filling her eyes. "The sigils I carved should help. One is usually enough to help the fertility of an entire town, I carved 33."

"I gotta ask, how did you make the sisters showing up sound so real? It was exactly like it happened that day" Shiny asked, fondly remembering the first time this scene played out, when it had ACTUALLY been the Royal Sisters chasing him like hounds instead of the roleplay his little sister kinked so hard over.

"I have a better question." Twilight asked as she glared at him lightly "did you REALLY start speaking Neighponese before going down on me?!?"

"Hey! It's only polite to say thank you before eating a delicious meal!" Shiny asked with faux offense as he put his hand to his chest.

"Nerd! You're lucky I love you."

"Yes I am Twily, yes I am."

*CANTERLOT CASTLE*

An amber Unicorn strolled through the mirror into the chambers Mom had set up for her on her oh so infrequent visits. To Sunset it had only been a few years since she had come home, but time moved a little differently in Equestria. It had been over a decade here. She and her Mom and long reconciled that allowing the mirror to return to it's normal thirty moon cycle was safest for Earth. Less magic was likely to leak through that way.

As she made her way to the throne room to meet with her mom and Aunt Luna, Sunset noticed two things, well, three actually. Noticing these things made her start charging her magic for a quick teleport.

With a pop of displaced air Sunset popped into the throne room to the sound of the Royal Guard snapping a dozen spears in her direction all at once. The guards thankfully relaxed as they recognized the red and gold streaked mane of their absent princess.

"Mom!! Can you explain why in the raging pits of Tartarus I have wings all of a sudden?" Sunset Shimmer shrieked only to stop short at the sight of her heavily pregnant mother and Aunt on the throne.

"Hello Sunset my dear" Celestia said serenely laying one hand on her swollen belly and summoning another smaller throne with a wave of magic. " You better sit down, with those wings appearing, we have a great deal to talk about."

Luna spoke to their aide Raven Quill quickly. "Best prepare an Alicorn strength dose of Moon Tea for her before it hits her."

"Before WHAT hits me?!?" Sunset asked in a panic as she started to sweat profusely and her nethers started to feel as if she would burn the stitching out of her jeans.

With a mischievous grin Celestia replied "I know it's been a while since your Equestrian Law classes but do you remember the First 100? Specifically statute 100, Section A, subsection B3?"

With pupils rapidly shrinking to pin pricks and eyes widening as her jaw dropped Sunset stammered. "Y-You're pregnant. I'm an Alicorn and my crotch is burning so badly it might as well be deep fried. I'm fucked aren't I?"

With a troll like smirk Celestia replied "Not yet! But you will be!"

Author's Note

Sorry for the long delay but I was trying to work out a Collab with this chapter. Sadly it didn't quite happen. I'm cool either way, honestly, things happen and 2020 was freaking weird.

That said the reality of this situation has now been revealed. As I said I don't write rape.

Shiny is a willing and enthusiastic participant in this rauchy debauchery and has been since the beginning.

Twilight is a nerd and gets off on Roleplay, their first sexual encounter is a particular turn on for her. And it all happened like this with a few modifications.

The first time there was no unwillingness with Luna or Celly nor did Cadance lock down hair junk to manipulate him. She only did that this time to work with the magic Twilight was working to try and help her get pregnant. Though he DID run to Twilight the first time to try and get a break when the Heat caught her. They had agreed to ignore the law due to their relationship at the time. Biology said Screw that. Now it's her favorite roleplay for the bedroom.
