With the advent of Nightmare Night came unintended consequences. One of those was visited on Spike, and his twin counterpart from Equestria, who had been left in Fluttershy's care upon Twilight Sparkle's visit. Her own twin had exchanged places with her to explore Equestria for the day, the princess eager to see the human world again and the doubles of her friends.
None of them expected the black mass of clouds that swathed a crimson moon. Darkness fell over the town, the girls and pair of hounds holed up in Twilight's mansion for a sleepover. The pair of Spikes howled in unison, their fur standing on end.
“There, there.” Fluttershy traced their toned backs as they continued to growl and slobber. She shivered, like the rest of her friends garbed in naught but a nightgown, bra, and panties, which hugged her voluptuous physique that threatened to spill out.
Rainbow Dash, whose slender but athletic form hadn't even bothered with a gown, approached a window and peered through the shudders outside the window. “What did you hear out there, boy? Is some perv trying to creep on us?”
“Almost couldn't blame 'em,” admitted Applejack, the tall mass of muscles and curves dotted in freckles, particualrly on her cheeks, breasts, and buttocks. She had reluctantly abandoned her stetson but still wore a ribbon at the bottom of her hair.
“I'd sure give them a party,” teased Pinkie Pie who also hadn't bothered with more than a bra that barely contained her ample tits and a thong, her flesh jiggling as she bounced over to the window and pushed Dash aside with a wide hip. Gasps arose from behind her when she unclasped her bra from behind, let it drop to the floor, and mashed her breasts against the glass.
“Pinkie,” cried Rarity, her well-shaped form shifting under her gown. “Desist at this instance!” Yet her words went ignored, spurred on by Dash's whistles and cheers, as Pinkie beamed wide and slowly dragged her pancaked tits in slow circles.
“Knew you'd take the dare,” teased Dash who hooked her fingers into the hem of Pinkie's panties and slowly peeled the lacy garment down, her pert ass slowly exposed with a hint of the party girl's cunt, a thin trail of its nectar connected to the cotton crotch. They were drawn down her ankles, only to be kicked off, as Pinkie stood completely butt-naked before them.
A loud slap on Pinkie's ass reverberated, the cheek left to wobble, an angry red hand print left on it by Dash. Flutterhsy half-turned her head and covered her face, still peeking through her curtain of soft pink hai and between her fingers at the sight.
“Absolutely shameless,” said Rarity, who nonetheless sneaked out her cellphone and started to record the event. She hated to admit it, but her loins had started to enflame, her thighs pressed closed where she sat in attempt to hide a moist spot.
Twilight Sparkle, who had watched in silent wide-eyed fascination, reached for her own phone, unable to help but tremble and sweat. “I...I'd better recod this,” she mumbled as she joined in with Rarity. “For scientific purposes, of course.”
“Of course,” replied Rarity who zoomed in on Pinkie's plush ass.
Fluttershy tried to keep hold on one of the Spikes, who slipped her grasp and padded forward. An “Eep,” escaped Pinkie as the dog's moist muzzle suddenly pressed between her asscheeks and brushed against her wet pussy slit. “Ooh~!”
“Bad dog,” cried Shy who hurried to her feet to intercept him. Yet when she hurried forward, she stepped on her gown and splayed onto all fours as the silk practically ripped in half and left her panty and bra clad skin exposed.
Seizing on the luried sight before him, the other Spike launched at her, like his other half his eyes turned pure, milky white, like he had been possessed. She yelped when he settled his mass over her, forelegs hooking around her midsection and hips hocked in preparation to mount his bitch. “Spike? Ah~,” she cried as his red cock pushed aside her panties and plunged in.
She seized up and full-faced blushed as he pentrated her with a lewd schlick. Her cunt seized around the intruder, dripped down her inner thighs, spread wide open when his knot swelled to split his bitch open and he started to hump into her.
Shy couldn't help but pant and whispered almost inaudibly, “Not in public.” She had done this with him a number of times in secret when she watched him, the beast primed to take her whenever she assumed the position like a bitch in heat. But if the hound heard her he ignored the words, as he started to thrust harder, her buttocks slapped each time his hips connected.
“Goodness,” said AJ who blushed and squirmed as her own heated hole slickened further.
Resigned to the fact that she had went this far and the crazed beast wouldn't stop until he spilled his seed in her, Shy sighed and unclasped her bra. Her pendulous tits, onced freed, swung and slapped together. They were topped by wide inverted pastel pink nipples that were teased out as they brushed over the carpet, and Spike used his claws to shred the offensive panties that blocked him, her tight pink asshole exposed to him as he drooled on her back and rocked her each time he hammered in-and-out.
Twilight ran to fetch the magic detector her twin had left and stared at the machine which violently throbbed in her grasp. “Something supernatural is happening, alright. Is it because of the moon? Both Spikes seem to be affected...”
“Who cares?” Pinkie giggled as she too was pushed onto all fours by the other Spike who mounted his bitch.
“That's right, this is awesome!” Dash squatted down with her phone close to Pinkie's pussy as she too was taken like an animal by the beast. Eager for her own turn as Pinkie was penetrated, Dash rushed to cast off her scant garments.
Rarity muttered, “It is somewhat warm in here.” She raised her gown over her shoulders and chucked it aside. Seeing as two of her friends had denuded themselves, she slowly undid her bra, let it drop, and her pale tits bounced loose. She then rolled down her panties and kicked them aside, her pubic hair trimmed like Shy's in contrast to Dash's and Pie's shaved snatches.
Twilight's cheeks colored. “I-I think the moon's affected us as well.” Yet the cloud of lust rolled over them unimpeded, as AJ slipped behind her. “Huh...?” She felt firm hands unclasp her bra, released her average-sized tits, and yank down her panties.
“Thought I'd help you along,” said AJ who flushed when she turned to her. “Make it even, ya know?” She undid her own top, freed freckly floppy funbags, then stepped out of her panties, her crotch covered in a blonde bush.
“Er...thanks,” said Twilight who nonetheless felt her heart quicken, spurred on like the rest of them. The animals had been first to surrender to their basest instincts, and once ignited the rest of them were quick to follow as their minds dulled by desire.
She realized this wasn't end until they were all satisfied, so she might as well surrender and enjoy herself. From here she could see the hounds hump away at their primed bitches, Shy and Pie left to pant and squirm and quiver under the beasts.
The dogs cast back their heads and howled in unison. Fueled by lust, their muscles started to visibly expand, transformed as they slightly enlarged, and a second penis rose from each and landed with a smack between the asscheeks of their lovers. The red wet mass traced over their assholes, before they plunged in and double-knotted the bitches to squeals of approval.
“Oh god~” Shy's words were lost in a shameless moan as her eyes rolled into her head and she squirted on her invaders, split further open as the twin cocks divided her lower holes, separated by a thin layer of hot flesh as they practically rubbed.
Pinkie squeaked shrilly as her own eyes rolled and she also came over her intruder's knots, which swelled further in the pair of bitches, drove open their cervices as they came, and locked themselves deep in their wombs as they continued to messily squirt.
Growls rose from the dogs who humped harder, spurred on to dominate their bitches and fill them with their seed. At this point schlicks sounded from Dash who shamelessly fingered herself to display in spatters of her own juices.
Rarity more subtly fingered herself and toyed with one of her heavy tits, biting her lower lip as she practically purred. She tensed up slightly when hands cupped her breasts, then relaxed under AJ's tender touch, as she was sensually kneaded.
Crawling on all fours with the dogs still knotted in them, Shy and Pinkie met face-to-face and locked lips as they were taken. Sloppy kisses sounded as their mouths locked and their tongues wrestled, reaching to feel each other's suspended, bouncing tits.
So turned on was Twilight that she completely threw caution to the wind and shoved the magic detector into her cunt. The cool metal filled her to a moan, drove her open as her pussy drooled down the handle as she rapidly pushed it in-and-out. “H-have to warn Sunset,” she whimpered with the last of her sanity as her free hand typed a clumsily written text into her phone.
More howls came from the hounds, who with one last thrust cast back their heads, teeth bared, and started to unload into their bitches. The throbs of their cocks in the tight rings of hot flesh made Shy and Pie clenched down further as they creamed themselves once again, their slimy wombs blasted by shot-after-shot of viscous dog come that splattered their walls.
Once the Spikes finished, they turned ass-to-ass with their breeders, and strained to withdraw, determined to seed every last bitch here before the night was done. Thankfully with a little help from Dash one came free of Shy, desperate to take her own turn as she went immediately to all fours. Spike licked his chops, knots still half-erect as he pushed against her lower holes and plundered them. “Hell yeah,” she cried as her tightness was impossibly widened as he started to swell inside her.
The other girls rushed to claim the other Spike. “Mine,” cried Rarity who shoved AJ aside, Twilight unable to keep up with their mad run. She presented herself on all fours to Spike, who popped free of Pinkie and mounted his new bitch. She tittered and prostrated herself, claimed by the mad dog who bit the nape of her neck as he skewered her hot pink holes.
She and Dash also made out and felt each other up. Their bellies swelled up heavily by doggie spunk, Shy swung a leg over Pinkie's face and settled her wide bottom onto it, met by Pie's giggles as warm cum leaked from the snatch and asshole in front of her to splash over her face. They buried their faces in the orifices presented to them as they started to lick the semen out.
With a disappointed groan, AJ instead pressed her pussy to Twilight's. Their inflamed slits connected, their clitorises kissed, swollen and damp, sticky trails left connected in thin trails each time they withdrew their hips them slammed back.
A rattle sounded at the lock and the door was kicked open. “What the-?” Sunset Shimmer, dressed in her usual blue attire, jacket, and boots, stared at the sights before her as the wind howled at her back. Her cheeks burned as she closed the door.
“H-hello darling,” managed Rarity between kisses, her tits left to sway each time she was impaled balls deep like a bitch.
“S-sorry,” said Twilight who continued to hump back against AJ, grinding their messy cunts together. “I couldn't-”
“Don't worry about it,” replied Sunset who removed her jacket with her own resigned sigh. She had seen her share of weird magic in her time and certainly dealt with far worse. So she shed her own clothes, until the shapely woman stood naked too. She started to feel up her own bulbous tits to warm herself up, determined to help the Spikes drain their balls dry.
Fortunately, more howls split the air with a final hump as they filled Dash and Rarity, who had came on them several times and left a slimy pool below as their lubrication continued to drizzle down their inner thighs.
“Our tun,” said AJ as she withdrew from Twilight and the duo crawled over. After some tugging they helped pry the sepnt doggies free, lowered themselves, and were taken by the savage beasts who wasted no time in pentrating their fuckholes. Her well-toned, freckled ass jiggled under his assault, as did Twilight's much smaller but heart-shaped posterior.
Dash and Rarity, stomachs swollen, joined Pinkie and Shy in a daisy chain where they cleaned out cum-soaked funholes. Sunset grit her teeth and stroked her clit harder at the sight, a hand still cupped around a tit she squeezed and kneaded.
Drool dribbled down AJ's and Twilight's backs as the muscular hounds slammed their bitches. They hissed and panted like they were in heat, made out and felt each other up, nipples pinched and twisted as they completely submitted below them.
Sunset hated to admit it, but she'd never seen anything hotter in her life. She didn't worry about the same taboos as humans did, since clothes were unnecessary and interspecies relations were common in her birth world, yet awareness at how shameless and perverse this was to the rest of them only made her clench her nethers further as she groaned in frustration for her own ride.
Flesh slapped and the hounds pounded away. They roared in victory and once more fired their cum into their uteri.
Once the Spikes pulled off with wet pops from gaped holes, AJ and Twilight added to the chain while Sunset presented herself like a bitch to both of them with a leer. One mounted her from behind and stabbed into her lower holes, while the one in front shoved one cock down her throat, his other moist tool, still soaked in cum and cunt nectar, left to slap hotly between her eyes.
The duo started to hammer between their Sunset sandwhich, left to shake as she was ruhtlessly battered between them. She surrendered to them, soaked them as her tits smacked, her mouth, twat, and ass annihilated under their angry assault.
Squirts soaked their cocks and balls as they ravished her wrecked holes, growls loosed as they made her their latest bitch!
A cry came from her core as Sunset felt them fill her. Her stomach distended under excessive cum that sloshed inside her, pulsed down her throat and all over her reddened face as the dog dick nestled between her eyes fired off its own excessive payload. Her face was soaked as it was hosed down, forced to close her eyes as spunk drizzled down her cheeks, onto her lips, into her mouth.
By the time they withdrew she was pleasantly sore. Yet somehow the hounds were hard as ever. She had no doubt this would carry on into the dawn and perhaps beyond, as Rarity and Pinkie presented themselves again and were freshly claimed.
She lost track of how many times all of them were fucked. All that mattered was that everyone satisfied their baser desires!
