Night Mares 4.5

Twilight Sparkle unhurriedly made her way down the stairs toward the front door of Pinkie Pie's house, casually pulling on the clothes she had discarded just minutes earlier. In contrast to the purple princess's demeanor, the doorbell's ringing went from polite to insistent, and the alicorn smirked as she deduced who it could be at this late hour.

Each of her fellow Element-bearers were accounted for. The princess had personally attended to every one of them that night, after all, using her newfound dark powers to unmask their deepest fantasies. She left them exhausted but satisfied, unconscious and splayed out lewdly about the pink pony's home.

So if it wasn't them, that left only...

"Hello, Sunset Shimmer. I was worried you weren't coming tonight," Twilight said as she opened the door, feigning her familiar, thoughtful sincerity.

The anger that had welled up in the impatient, fiery-maned unicorn quickly sputtered out the moment Twilight opened her mouth. Even after a stressful day and a trudge through the bitter rain, Sunset found it difficult to get mad at the Princess of Friendship.

"I didn't think I was, either, but then I heard you guys were in need of a reload." The orange-furred unicorn grinned as she held up a 24-pack of soda. Twilight returned the smile and stepped aside to let her friend, and her precious cargo, in.

"Where do you want this? Kitchen?" Sunset asked, already on her way there as Twilight closed the door behind her. A look of alarm flashed across the princess's face before she hurriedly barred Sunset's way, then politely took the soda off the unicorn's hands.

"R-right here's fine!" she said, setting the soda against the living room couch. Blues and whites from the television flickered off Sunset's face, an eyebrow cocked questioningly before Twilight finished with, "You're... dripping water everywhere."

Sunset's eyes widened in realization, and she sighed as she trudged back to the front door. "Ugh, I'm such a horrible guest, getting Pinkie's carpet wet."

As she turned her back to Twilight and shrugged her raincoat off, the princess found, to her delight, she wore her sleepwear underneath: tasteful teal pajamas that matched her eyes and contrasted with her natural red, yellow, and orange coloration. Unaware she was being watched, Sunset bent over to meticulously remove her boots, and Twilight couldn't help but sneer devilishly. "That's not the only thing getting wet," she muttered.

Oblivious, the unicorn casually snatched a can of soda and asked, "So where is everyone? Don't tell me you guys are actually sleeping during a sleepover."

With a playful chuckle, the alicorn replied, "I guess this is what happens when there's no soda." She narrowed her eyes and helpfully added, in a sultry tone, "You really should come earlier next time."

As the words sank in, Sunset paused mid-swig, lowering the can in her mouth just enough to see Twilight smiling wide-eyed and innocently back at her. Did she really just say that? The unicorn shook her head and shrugged it off. "I... don't believe you," she said as she gestured toward the TV. "Not like AJ and Rainbow to leave their game running."

"Oh, they found another way to settle their rivalry." Before Sunset could ask what exactly Twilight meant by that, the alicorn continued: "You like video games, too, don't you?" Her lips twisted into the most competitive, instigative smirk she could muster. "Think you can take me?"

The unicorn blinked, completely caught off-guard by the princess's challenge. Meek, bookish Twilight was challenging her! To a video game, of all things! It took all of her willpower not to choke on her soda, and some of it burned at the back of her nose and throat as she stifled a burst of laughter. Sunset, with effort, played it off cool, though, finishing off the can before casually tossing it aside like the horrible guest she was. "Bring it."

“Hah!” Sunset Shimmer cried triumphantly, leaning back on the couch and turning to her friend. “Looks like I win again.”

Twilight Sparkle huffed, feigning frustration, making the unicorn dial back her victory celebration a tiny bit. “For what it's worth, you did better than I expected. I mean, I didn't even know you played,” Sunset said, trying to sound as encouraging as she could.

The alicorn smiled back sincerely, even blushing a little. “Thanks for trying to boost my morale, at least.” Her eyes sought the unicorn's, and as their gazes locked, Sunset couldn't help but smile back.

Suddenly, a brief glint of malevolent violet energy flashed across Twilight's oculars. It lasted less than a heartbeat before Sunset's magical defenses instinctively kicked in, but enough of a connection was established: Twilight learned all she needed from that split-second of contact.

The confused unicorn blinked, unsure what she just saw, but before she could ask, the alicorn's challenging smirk returned. “Up for one more?” the princess asked, voice filled with renewed confidence.

Still visibly unsettled, the fiery-maned unicorn nodded. “Your funeral.”

Sunset hunched forward on the couch, focusing once more on the game. Still, the unicorn couldn't help but notice her friend sidling closer and closer to her. Their hips were inches away from touching, while purple wings brushed against her sun-colored mane with feather-light touches. Maybe that was part of the game, too. “Heh, you're not gonna get in my head that easily, Twi.”

The purple princess's grin only widened in response. The game continued, and the room soon faded to just the sounds of the television and the sporadic clicking of buttons and thumbsticks.

“Wow, it's like you're not even trying,” Sunset remarked, another victory close at hand. But before she could finish Twilight off, the unicorn gave a startled gasped when a pair of familiar purple hands suddenly reached around her waist and cupped her breasts. It quickly dawned on her that at some point during the game, Twilight had somehow stealthily wedged herself behind her on the couch.

“I guess I got distracted,” the alicorn purred, her muzzle nestled against Sunset's ear.

Sunset froze, while Twilight's ministrations continued. The alicorn nuzzled and licked her friend's ear teasingly, while her hands boldly groped and fondled the unicorn's chest. It wasn't until she started undoing the buttons on Sunset's pajamas that the unicorn snapped out of her stunned silence, clasping her hands over the alicorn's.

“Whoa, easy there, bookworm. I'm, uh... happy that you feel this way, but this might not be the bes- Ah!”

Twilight interrupted her friend by taking the unicorn's horn between her lips. The alicorn stroked her tongue all along its spiral length and sucked on its tip, silencing Sunset's protests. With the unicorn caught off-guard, she finished unbuttoning her top and pulled it open, then brazenly dug her fingers into Sunset's bra to toy with her tits.

The unicorn let out a soft, pleasured gasp as she melted into her friend's intimate touches. The provocative suckling on her horn left no doubts of Twilight's intentions. And who was she to deny the Princess of Friendship? Letting go of the alicorn's hands, she set to work helping her along, shifting and shrugging her top off, then unhooking and removing her bra.

Twilight's smile widened around Sunset's horn as the unicorn came around to her plans, her fingers circling and massaging her breasts while occasionally teasing and pinching the hardened, attentive buds capping each firm mound. Momentarily setting Sunset's horn free, Twilight huskily whispered in her friend's ear, “You like playing games, don't you?” The alicorn's horn lit up, purple auras surrounding each of the game controllers as she yanked them out of the console. “How about letting the games play with you for a change?”

Sunset's eyes followed each controller as they danced and swirled in front of her. She didn't resist as Twilight pulled her wrists back and bound them together behind her head using a controller's cord. With her elbows bent, her shoulders pulled back and her back slightly arched, the unicorn's modest chest jutted out proudly. The alicorn licked her lips hungrily as she intricately looped coils upon coils of controller cord all along the unicorn's torso, tying her breasts and her body up in an impressive, albeit lewd, display.

Once done, Twilight climbed off the couch and stood in front of the bound Sunset, inspecting her work. The unicorn squirmed as she tested her bindings, surprised by how tight they were. She snickered and shot a playful, mischievous look at the alicorn. “Been reading some interesting books, huh?”

Twilight's grin bordered on maniacal as her purple auras held up more unplugged controllers. “You have no idea, my dear.”

Her work obviously not done, the alicorn nonchalantly peeled off Sunset's pants, leaving the bound unicorn in nothing but a pair of white bikini panties.

Sunset gulped as Twilight sauntered between her legs and knelt there. Hooking a single digit to her underwear and pulling it outward, the alicorn brought her nose right up against Sunset's mound and inhaled deeply, then blew warm air over the hidden, sensitive slit. The unicorn could only shudder and squirm with anticipation.

The alicorn licked and kissed up along the unicorn's body, her lips starting dangerously close to her sex, trailing over her navel and trapped mammaries, delving into the crook of her neck, and finally ending on her muzzle.

Sunset's eyes narrowed to slits as she shared a deep, passionate kiss with Twilight, the discomfort of her bindings pushed to the wayside. This wasn't the warm welcome home she expected, but she certainly didn't mind! The alicorn leaned on her, pushing her back against the couch, fingers busily groping her bound breasts once more.

“Time to play,” Twilight said, her voice taking on a darker tone as she wedged a controller into Sunset's panties, the tightness of the garment holding it snugly against her sex, one end digging into her folds. The unicorn squealed as the controller hummed to life, her thighs instinctively trying to squeeze shut as jolts of sensation rushed up her spine.

“H-how?” Sunset asked breathlessly, heat rushing to her cheeks as the game paddle buzzed ceaselessly against her sensitive flesh. “It's not even plugged in!”

Twilight's devilish grin widened as she ground the vibrating controller against Sunset's lower lips. “Magic,” she answered. Her hands kept busy toying with Sunset's breasts, roughly fondling them while she slid the video game controller-turned-sex toy back and forth across the unicorn's slit. “You love this, don't you?”

Sunset clenched her jaws tight, her heavy breaths and grunts the only vocalizations of her enjoyment. But she couldn't hide her shameful blush as her body betrayed her lust through other means.

“Oooh, I think I found your Start button!” Twilight said, and the unicorn let out a stuttering, quivering moan as the toy pressed against her aroused clit. “You're not like the others,” Twilight continued, assaulting the trapped unicorn's nub again and again. “You were almost powerful enough to be a challenge.”

Sunset was barely processing the alicorn's cryptic words. Her hips moved of their own accord as she twisted and squirmed against the couch, half trying to pull herself away from the mind-numbing stimulation, half trying to ride it over the edge.

“But I figured out your defenses... Figured out your desires.”

Sunset panted and moaned, the relentless vibrations upon her sex making it impossible to form any coherent thoughts.

“Give in to them,” Twilight purred into the unicorn's ear.

Sunset obliged. Climax claimed the orange-furred unicorn, and she let out a breathless, stuttering cry. Her mind whirled in chaotic bliss as her entire body shuddered spasmodically, arching and twisting in the throes of orgasm. The controller glistened with the nectar leaking from her nethers, and it wasn't until her cries died down to whimpers that Twilight finally pulled the diabolical device away from Sunset's puffed, dripping folds.

Sunset was in a daze, barely aware when the alicorn pulled her bikini panties off, stripping her bare. She didn't even notice when Twilight turned around and undressed herself. It wasn't until the purple alicorn faced her once more that she snapped out of her blissful haze, eyes immediately drawn to the veiny, throbbing horsecock between Twilight's legs. “Wh-What the fu-ngh!”

A purple aura suddenly surrounded Sunset's sex, stroking the sensitive flesh and spreading her folds, causing more of her fluids to leak out. “Like I said, almost a challenge. But what good's your magic when you're so easily... distracted?”

The unicorn struggled desperately in her bindings as the alicorn magically molested her. Twilight was right, of course. Drained from orgasm and too aroused to think straight, Sunset was in no condition to counter the princess's spellcasting. The phantom fondling soon stopped, but Twilight was far from done.

Sunset whimpered as Twilight gripped her ankles and lifted her legs. A controller cord coiled around her right knee, then looped around her right elbow, tying them together. Despite her squirming, her left limbs soon received the same treatment, leaving the unicorn unable to close her helplessly spread legs.

Satisfied with her work, Twilight then leaned over Sunset, the fiery-maned unicorn now at her mercy. “Awww, don't act like you don't want this,” she teased, grinding the base of her length along Sunset's slit. “I know you haven't had a good dicking since you've returned to Equestria.”

Sunset tried desperately to gather her thoughts, to weave a teleportation spell together and escape. But Twilight's lips soon found hers, the alicorn's tongue snaking into her muzzle and coiling around her own. Shudders of sensation rippled through the trapped unicorn as Twilight dragged her throbbing length back and forth across Sunset's attentive clit. By the time the alicorn lined the tip of that organ against her folds, the unicorn was yearning for her to put it in.

Twilight broke the kiss, her unnaturally long tongue slurping back into her mouth as she shot the unicorn a sinister grin. “Consider this your welcome home.”

Sunset arched her back and let out a breathless cry as the first thrust drove the wind from her. The corrupted princess buried more than half her length in the unicorn in one stroke, and Sunset's vision clouded from the initial, painful shock. That sensation quickly faded, however, and was replaced by a feeling of fullness that could only come from being filled to the brim by a stiff, equine cock.

Twilight held her shaft half-buried in Sunset, reveling in her tightness. As the unicorn adjusted to her size, she could feel those warm, velvety reaches gripping her pulsing organ. She would not let Sunset completely regain her composure, though, and with a devilish smirk, she began thrusting.

Sunset gasped and grunted, muttering soft expletives as Twilight assaulted her with short, rapid strokes. The alicorn was meticulous, never fully hilting inside her. Instead, the unicorn could feel Twilight's medial ring flicking over her clit and stretching her entryway with each thrust. It was deliberate, of course, and it was driving her wild.

The unicorn's face twisted in a mixture of anger, shame, frustration, and want, and Twilight reveled in the conflicting emotions. “You put up a strong front, Sunset Shimmer,” she said as she harshly thrust the rest of her shaft into the unicorn's wet, winking sex. “But underneath that tough girl act...” The alicorn withdrew her length until her medial ring slipped out with a squelch. “You just want to be tied up and fucked...” Her hips slammed home again, wrenching a cry and a spasmodic shudder from Sunset. “Like the slut you are.”

With that, all pretense of lovemaking was gone. Twilight's hips became a blur as she pounced on Sunset and truly began fucking the mare. Each thrust was punctuated by a wet slap, the corrupted princess's balls swinging lewdly against the orange-furred equine's rump. Even as she started to pant and moan with exertion and excitement, the triumphant grin never left the alicorn's face.

If Sunset couldn't concentrate before, she certainly wasn't able to now. The Princess of Friendship's rapid, firm strokes took their toll, and the unicorn's thoughts were completely addled with desire. Moaning lustfully, Sunset twisted and squirmed in pleasured reflex, her bound body succumbing to the overpowering heat emanating from her sex. Instinctively, the unicorn met each of the alicorn's thrusts with a rough buck of her own.

Neither of them would last long, but it was Twilight who gave in first, her eyes glowing violet as dark magic channeled through her. With a triumphant growl, the princess hilted one last time before her corrupted cock erupted inside the unicorn's rippling, clenching walls.

Hot seed geysered into Sunset's slickened tunnel, and the bound unicorn spiraled into climax. All coherent thoughts melted into chaos, liquid pleasure flooding her mind just as the juices of her lust gushed out of her depths. Her warm nectar coated Twilight's rampaging, twitching column of horse flesh, spilled out her puffed sexlips, and pooled messily on the couch.

Grinning as her latest conquest melted and convulsed around her hardened shaft, Twilight's thrusts grew less and less frantic, until she slowly withdrew her cock from Sunset, causing a fresh, sticky spill of their mixed fluids. The unicorn shuddered in response, letting out a blissful murmur, which turned into a shrill cry of protest when the alicorn suddenly speared two fingers between those over-sensitive folds.

“Mmm... Exquisite,” Twilight said as she withdrew her fingers and licked them clean.

Sunset's gaze was first drawn to Twilight's glistening fingers, and then snapped to her still-glowing oculars. Her eyes suddenly widened in recognition.

“D-dark magic? Twilight, you shouldn't...!” The unicorn stopped short as five more pairs of violet orbs suddenly lit up around her.

“Oh, save it. It's not like you've never given in to the allure of overwhelming power yourself." The unicorn winced, Twilight's words hitting home. She squirmed nervously in her bindings when it dawned on her how corrupted the princess had become. "At any rate, I'm touched that you're worried about my well-being. But I think you've got bigger problems to deal with.”

Each of the other five Element-bearers stepped within the flickering glow of the still-running television, and each one of them sported a hefty equine cock between their legs. Wearing nothing but sinister grins, they surrounded the bound unicorn.

Sunset pulled and strained fruitlessly against the cables that still held her spread and helpless, but there was no escape. Physically and mentally drained, the unicorn could only whimper as a certain rainbow-maned pegasus lined her thick member up against her gaping, drooling folds. With a sudden, unceremonious thrust, the hellish night continued...
