Author's Note

And here we are at the Grand Finale, get your lotion and tissues ready, it's about to get... Lewd.

In which Somber Shade and Twilight Sparkle do unspeakably lewd things to each other

Twilight

Twilight took a deep breath and mentally went over her mental checklist.
Shower? Check.
Room clean? Check.
Makeup? Check.
Mane styled? Check
Tail braided? Check
Sexy lingerie Rarity gave as a gag gift? Check (but it's a bit... Small).
Thigh-highs and elbow-leangth fingerless gloves? Check (thanks Luna)
Mood lighting? Check.
All that was missing at this point was Somber Shade's thick ass cock splitting open the Princess of Friendships' cunt and finally quenching the burning heat that had been driving her insane! Then, after a nice long nap and another shower, maybe the two can talk about the future. THEIR future.

"Oh goddess this wait is killing me, where is that stupid, sexy, stallion!?!" She fumed aloud, glancing at the door.

It was nearly 9:00 PM, when Shade's Shift starts, and soon he'd be there, in her room, ideally letting her teleport his armor off so they could just get to it. Twilight sighed as she let her mind wander, fantasies most lewd playing in her mind for just a moment before she heard it. The knock she'd been preparing the last 4 hours for.

Quickly Twilight teleported onto the bed, lounging atop the soft blanket on her side to show off her ample assets in slightly too-small lingerie.

"Come in..." She called out in a singsong voice

Shade

Shade gulped hard as he waited for Twilight to respond to his knocking at her door. Truth was he'd been standing in front of the door, wearing his usual work attire, while trying to work up the courage to just KNOCK!

'I've fought Changelings, Dragons, Yacks, and a Hydra without even thinking twice but helping my Princess relieve her heat and possibly discussing how we feel about each other after is what's got me scared... Figures.' He thought, before hearing Twilight's singsong reply to come in.

With one last deep breath Shade took the doorknob and quickly turned it open, walking through the door and heading to the bedroom, locking the door behind him.

To say that Shade was Blown away at the sight of the Princess would have been an understatement. She was radient, laying upon the bed like an angel, wearing a set of matching dark purple lingerie, thigh-high stockings, and elbow leangth fingerless gloves, topped off with tasteful applications of eyeshadow and lipstick. Sure, the bra was a bit tight, and the panties looked liable to snap from the strain of wrapping around her wide hips, but that just meant it wouldn't be a problem if he ripped them off her. Hopefully.

Twilight blushes and moves off the bed to greet Shade, smiling warmly as her breasts bounced ever so slightly with each step.

"You like what you see, Handsome?" She asks in a teasing tone

Shade nods dumbly, practically drolling over her, before finally managing to find his words.

"You look stunning... Like something out of my dreams." He says, closing the gap between them and gently reaching up to cup her cheek. His dark blue eyes gazed into Twilight's dark purple orbs (in her head this time) and quickly locked his lips with hers.

The two groan as they share their first kiss, their shared arousal quickly heating the exchange, and soon Shade found himself naked and teleported onto the bed with Twilight straddling his waist.

The alicorn gave her half-zebra lover a lustful look as she started grinding her plush backside against his rod, the unseen pillar of flesh quickly growing between soft ass cheeks.

Twilight

As she was teasing the naked stallion beneath her Twilight realized she hadn't actually SEEN the endowment she was rubbing with her butt, so quickly glancing back she had to double take and then stop in her tracks.

The average stallion in Equestria is 8 inches long, for Zebras is about 6, and Unicorns are a bit all over the place depending on breed. Somber Shade, now fully erect, was sitting pretty with a whopping 11 inches of near soda can thick cock meat hotdogging Twilight's bootycheeks.

"Shade... Did you know you've got a fucking huge dick?" Twilight asked nervously, biting her lip as she continued to grind against him.

"My father was a South Stafford Shire breed, Princess, from what I've heard we were bred specifically FOR princess breeding. This isn't even my full size though, I'm employing a size reduction technique my mother taught me." Shade Explained with a small prideful smile

Twilight gave a nervous gulp before raising her hips to let Shade's cock flop onto his abs for a moment before raising it in her magic and holding it up aimed at her soaked pussy lips, and resting herself against it gently. The princess took a deep breath as she looked Shade in the eye, the royal guard (and i guess long-term booty call now, we'll see) looking back and moving his hands up to her waist and giving the little bit of extra squish a small squeeze. With that Twilight Sparkle took a deep breath and slowly pushed down to let the fat flare of Somber Shade's cock stretch passed the enterance to her tight pussy.

Both groaned in a mix of pleasure and slight discomfort. Shade at the sheer tightness of Twilight's pussy, and Twilight at the sheer thickness of Shade's cock stretching her pussy... And this was just the first inch or so. The Princess took a deep breath and slowly began to rock her hips, relaxing so more of her lovers thick cock could slide into her soaked cunt, only stopping at the medial ring.

"Fuck you're big... I-I don't think I can take it on my own Shade... I need you to take chaOHMYGODDESS!!!" Twilight began to say before Shade grabbed her by the hips, rolled her onto her back, and gave a quick back slide out before suddenly SLAMMING the rest of his cock balls-deep inside her royal pussy like a jackhammer.

Shade had tried to remain calm and let Twilight do her thing, but the intense sensations surrounding his member drove him into a lustful frenzy, and for an instant he let his dominant instics take over. This suited Twilight just fine and she happily wrapped her legs around his waist, moaning happily as she began to push into his thrusts. Shade returns her lustful grin as he leans in closer, roughly kissing her as he plowed into her hard and deep. Their tongues would egarly wrestle for dominance, and Twilights fingers gripped Shades back as her sensitive body edged to it's first climax.

Shade could tell she was close, and while he was still ways away from cumming himself, he was happy to make his Princess scream in delight. Using a bit of magic the smokey grey unicorn stimulated the purple princesses clit ever so slightly while also angling his inward thrusts upward to hit her g-spot, thus pushing Twilight into a powerful orgasm.

Were it not for the soundproofing spell all of ponyville would have heard Twilight Sparkle, Princess of Friendship, soon-to-be ruler of Equestria, and general bookish shut-in scream the words 'Fuck me like the little whore princess i am Daddy!' And 'Make me your roal baby momma' at nearly midnight.

In the crystal empire

Princess Cadence suddenly sat up in her bed, eyes wide, panting softly.
Shining Armor, her loving Husband, sat up with her as she had awakend him.

"Babe, what's wrong, bad dream?" He askwd sleepily

"No Shining... I just felt a disturbance in the Kink-Force... Someones slutty side Just emerged and it was big enough to wake me." She explained, shuddering and biting her lip.

"Oh, okay... Wanna fuck before we go back to bed?" The blue maned prince asked with a smirk

"Dude, get out of my brain." Cadence replied before pinning Shining to the bed, thankful she married such a stud, and that they both slept nude.

Back with the title characters, no more detours

Somber Shade slowed his thrusts to a slow rocking to let Twilight recover, having nearly lost his hearing to her loud screams for more. The Princess of Friendship herself was flat on her back panting heavily, eyes slowly focusing on her slightly embarrassed lover.

"Oh... Goddess... That was incredible Shade. I-I'm sorry if i got too loud." She said breathlessly

"I'm fine. Glad to know you can handle that much, most mares pass out by now. Wanna see something cool?" Shade asked with a lewd grin

Twilight gulped nervously and gave a small nod, still somewhat dazed by the intense orgasm she'd just had, but she was curious what this stallion had in mind.

Shade took deep breaths as he began to focus himself, at first the Princess below was unsure of what was going on, but soon the warm tingle in her lower belly signaled something was going on inside her. It took a few moments for her to realize it, but soon it was undeniable: Shade's cock was getting bigger!
More and more his organ swelled inside her, an outline emerging from her lower abdomen, until it finally stoppeed. Twilight reached down and ran her hand over the bulge from just above her navel to her entrance where even more of Shades now massive fuckstick was left outside of her.

The princess took a few shuddering breaths while her eyes took in the sight, before closing them, focusing her mind, and slowly squeezing her inner walls around the cock lodged inside her.

"... 14 inches long, 3 inch diameter, 4 inch medial ring, 4.5 inch flare." She mumbled to herself before looking up at Shade, who looked at her with a perplexed expression.

"T-Twilight... Did you just measure my dick with your pussy?" He asked, a blush spreading across his face.

The purple alicorn nodded slowly
"Uh... Yeah... I learned it from a book Rarity loaned me, I never used it on a stallion though... Is it too wierd?" She asked, already embarrassed

"Weird? Twilight Sparkle? Hell no, that was the sexiest fuckin' thing I've ever seen! You're a naughty, nerdy, princess and I'm gonna pound your pussy till you're full of my cum!" Shade declared with a wide grin, pinning Twilight under him as he began to thrust his much larger cock into her.

At first Twilight could only gasp and squirm under him, his size and hard thrusts easily pushing the alicorn to cum over and over from the sensations the wide head sent shooting up her spine, but soon she found her voice and cried out as a particularly stimulating climax hit her.

"OHHHH FUCKING GODDESS YES!!!" She moaned as she clung to her darker hued stud.

Said stud was on cloud nine as he plowed into what felt like the cunt of a goddess, his fat nuts bouncing off purple booty cheeks, and his wide flare kissed her cervix. Somber Shade fucked Twilight like a mad beast, grunting and groaning in her ear, loving the sound of her own high squeals.

"I'm gonna bust the fattest fuckin' nutt in you Princess, you're not leavin' this bed till i knock you up!" He growled, reaching his hand up through Twilights mane to gently pull back.

"Fuck YES!! I need your hot cum... To fertilize my egg... And make a genetically perfect foal!!!" The princess begged, eyes starting to cross while her tongue stuck out a bit.

Hearing this seemed to set Shade off and the already energetic half-zebra briefly stopped to sit up while balls deep inside her, then lifted her legs over his shoulders so he could pin her in a true mating press, railing into her love-tunnel even faster and deeper. The flare of his onyx shaft battered Twilights royal cervix brutally, her inner walls clenching around it as she came over and over to the point of actually SQUIRTING all over the base of the shaft and balls.

This rapid pace, along with the dripping, squeezinf pussy, as well as the constant nerdy/lewd moaning (at this point Twilight was mostly begging Shade to "release the billions of sperm cells inside his balls"), was bringing him closer to his own climax. Shade felt his flare widen, Twilight went full Ahego, Shade let out a loud groan as his heafty balls pulled tight and began to audibly churn, while Twilight began to feel a powerful stream of liquid heat fill her womb. Shade was cumming hard as he continued thrusting, literally fucking his seed inside her, the Princess feeling more and more thick fluid fill her to the brim before it started to leak down between her ass cheeks.

It would be a few moments before the heavy flow of jizz began to taper off until Shades nuts were finally drained. Twilights belly was swollen from the sheer volume of seed that filled her womb, though that wasn't all that unpleasant.
'Thank the goddess for Alicorn physiology...' She thought to herself.

Shade held himself up over Twilight, panting heavily as he let her legs fall onto the bed and he slowly began to withdraw his slowly softening cock. The unicorn stallion grinned sheepishly as the flare literally popped out of her and cum began to leak out more before a seal was put in place by the alicorn princess. With that done Shade gave a heavy sigh of relief after flopping down onto the bed next to Twilight.

They were quiet for quite some time before, finally, the princess broke the silence.
"How did you make your dick that big?" She asked

Shade blinked in surprise before snorting and replying.
"Pff haha! Okay then, that's fair. Technically it's supposed to be like this, but most mares can't handle it at all, especially Zebra mares back home, so i asked the village elder, who taught me the art of cock-control. Now, how did YOU learn to measure dicks with your cunt?" He askec with a teasing grin.

Twilight blushed and chuckled nervously.
"I-I practiced with toys... And fruits... And vegetables... And other things... But yours was the first real cock i used it on. It's bigger than my biggest toy, and that one was cast in a mold of Big Macs." Twilight admitted, biting her lip.

It was Shades turn to blush, though he did give a slight smile to possibly being the biggest in Ponyville (though Snails did have him beat in terms of leangth), and after a long yawn he'd pull Twilight close and gently kiss her lips.

The Princess kissed back softly, loving the feeling of his hard body against her feminine curves, their tongues lazily caressing each other as they drifted into a post-coital slumber...

Little did they know someone WAS watching the entire affair, a pair of someones, from a far away place, who very much enjoyed the show...
