Only Chapter

It had started as an experiment. A way to remind Sunset Shimmer of home. But this was her home now, wasn't it? Sometimes Equestria seemed like a far off memory; a dream which made her heart ache at times. Yet she had grown attached to the people here and their strange customs, and while she could use the mirror on occasion to travel between worlds, she figured it wasn't something to be done lightly. Thus, she reserved such trips for special occasions when she grew too homesick.

Yet with the help of the Twilight Sparkle she'd met here and Flash Sentry the three had come up with a compromise. “Are you sure about this Flash?” She'd asked the question several times. “I don't want you to feel like a guinea pig.”

“Oh, don't worry about that.” His hands were in his jean pockets and he rocked back-and-forth in his sneakers. They were in Twilight's personal laboratory, situated in the basement of a house so large it more resembled a manor; with patents from her inventions she had quickly risen to wealth and used that to fund her research. “It will be a little weird, though.”

Twilight's lab coat swept past her when she rounded a table meticulously lined in schematics and equipment. She paused to look him over with an adjustment of her glasses. “Don't worry, I've brewed up something to nullify the effects if this doesn't work out.” She nodded at a beaker filled with a bubbly multi-colored liquid. “Now, are you ready to test our theory?”

Sunset swallowed when he took the concoction and sniffed it. Through a combination of science and magic the pair had worked it down to the last detail; still, she couldn't help but feel selfish about what she'd asked them to do. “Flash, you can still-”

He gulped it down before she could finish. His face scrunched at the bitter taste. “A-ah...” He groaned and dropped the empty beaker which shattered with a loud ring. “Feels like I'm on...fire...” His teeth grit and he swayed.

“Hold on.” Sunset dashed over and let him lean on her for support. “I'm really sorry, I-”

Twilight pursed her lips and narrowed her eyes. “It's working.” He cried out, clutched at his groin, which swelled to bursting. Soon his penis strained against his pants, and he hastily undid his zipper to provide some relief; only what spilled out over his briefs wasn't the average if well-shaped equipment he remembered. No, it now dangled between his thighs.

“It's beautiful.” Sunset slapped a hand over her mouth with a blush.

“It should be a fully functional horse penis. Exactly like you requested.” Twilight grinned at their work which had settled into place. The dark piece of meat flared at the tip, complete with a medial ring and lined with thick veins. Below them swelled a matched set of testicles. He slid out of his pants and underwear for blessed relief. “How do you feel, Flash?”

“Dizzy.” He rubbed his temple.

“Must be the rush of blood to the area. You should get used to it,” replied Twilight. “We also took those magic pills Sunset supplied us. You know, the ones that are supposed to simulate estrus? Minus the icky urination part!”

Sunset experimentally poked the tip. “Can I...lick it?”

“Of course,” he replied barely able to finish the words before she dragged her tongue across it. Grunting, his cock twitched and bounced, slapping her lips and slathering them in a glaze of precum that coated them. She took an experimental taste, moaning.

Twilight giggled, the odor from his pre helping the pills kick in. “That good, huh?”

Sunset nodded. “Rather salty, but I like that. Definitely reminds me of the real thing. Oh.” She wrapped a hand around his medial ring to keep him from going flaccid. “It would be rude to work you up and not finish, so-” She wrapped both hands around his stallionhood and slowly stroked it, the half-erect equipment soon swelled to full rigidity.

She kissed his urethra, pressed her lips to his flare and traced circles around it with her tongue. Her half-lidded eyes met his own, and he stripped off his skirt, casting it aside and staring down his chiseled musculature while she happily worked him over with soft suckles, tender kisses, and playful pulls with her teeth, her burning face almost as red as her hair.

Groans emerged from Flash, and he tentatively placed a palm upon her head; when she didn't resist he curled his fingers through her bangs and started to buck his sculpted hips. She opened wide to accept him, his cock sinking into her throat, and she greedily tried to devour it, gagging with a few small tears as in this body she wasn't used to taking anything near this size.

Still she pushed herself harder, determined to take him balls deep before he came. She didn't want to turn down a challenge, and besides, she felt like he was owed this after she'd dated him for so long before her reformation without ever giving him so much as a chaste kiss. No, she was going to give him the absolute best blowjob of his life, even if it meant she choked on his dick!

Knowing it was about to get messy, Twilight helped Sunset slip out of her clothes, which she resorted to tearing away when necessary. Her frilly pink panties with their tiny bowtie were absolute soaked at the crotch; Sunset popped off her lips for a moment and strings of saliva mixed with his pre tethered his flare to her luscious lips. “Wait, I have an idea.”

Twilight shared a sly grin with her. “I think I know what you have in mind.” She stepped out of her own lacy violet underwear, her own pussy drenched in ribbons of juices that connected to its stained groin. While Twilight awkwardly shirked her own garments, she and Sunset placed the slick areas of their panties around his cock, smearing the cunt nectar over his cock and balls until they were thoroughly drenched. She then knelt beside Sunset, helping her lick and nibble down his shaft.

“Hey Wallflower,” called Twilight and they followed her gaze to the nubile woman at the back. As usual she'd went unnoticed nearly the entire time, despite the fact that they'd invited her here, forgotten and left to operate the camcorder that filmed their latest experiment. Of course the slender nymph had taken advantage of that, stripping down and fingering herself.

“Y-yes?” Wallflower blushed and paused like a reprimanded child with fingers still buried in her moist snatch. Unkempt hair trailed about her, her perky tits and pert bottom decorated with freckles like her cheeks.

“Why not help out directly? There's room.” Twilight patted a spot by her. “Flash can play camera man, if he likes!”

“I would.” He smirked and accepted the camcorder from Wallflower, who scuttled by Sunset who took the middle when they commenced their triple blowjob; Shimmer clamped her mouth on his tip while the other two traced down his throbbing meat and swollen testicles. His musk was overpowering, driving them into a dull stupor, witless and ready to be bred.

Not that he fared any better. Bestial instincts compelled him to breed the trio. Glazed eyes met when they stared up at him, serviced him with lewd sucks and smacks, their mouths awash with his tangy need. He zoomed in on them, captured each salacious detail; and when his arm started to tire, he pressed a few buttons on Twilight's camcorder, her invention transforming with a whir into a helicopter drone that buzz away and continued to capture them from a bird's eye view.

Again his hands bunched into their hair, more forcefully this time, manhandling his herd when he drove forward and started to facefuck Sunset in earnest. She gagged some more but didn't resist, drooled down his length, her throat distended when he hilted deep as possible. Fresh tears ran down her cheeks, but she wouldn't have it any other way, driven to please him and herself in the process. Plus, she couldn't wait to watch the depraved porn they were making later!

“Unf,” he grunted slamming into her, his balls slapping her chin. Gradually he withdrew, then brutally thrust all the way back in, worked into a rhythm where he skullfucked his alpha bitch. She took it like a champ, his pre-ejeculate swirling with her slobber when it dribbled down her lips and chin to speckle her bulbous tits, by far the largest pair of the girls here.

At random he would draw back, and push into the mouths of Twilight or Wallflower instead; neither could remotely take him as deep, but he enjoyed poking into the wet insides of their cheeks anyhow. He made sure to give them all a thorough swabbing, claiming them for his own, but reserved most of his savage thrusts for Sunset, who he sensed was clearly the strongest of them.

“Open your mouths and stick out your tongues,” he demanded and they hastened to obey. Jerking himself a few more times with animal grunts and a cry that resembled a whinny, his rod pulsed and his flare erupted. A comically large thick rope of horse cum launched across Sunset's hair, slapped her face, and made her wince with a cry when she was shot in the eye.

It stung and she closed her eyes but held her ground, her features coated in spunk that flopped all over her tongue and onto her sweat-soaked breasts. He seized the other two by the hair, hosed them down in a similar manner, taking turns dousing them in virile, slimy sperm that slathered down their faces and curves, their messy features now thoroughly cake in foal-batter.

He was still jerking out the last weak sprays when Sunset pulled Twilight and Wallflower into a shared kiss with her. Greedily she slurped up the splooge from their mouths, a bubbly soup which clung to their gums and the warm roofs of their interiors in gooey tendrils, the saltiness jammed between their doused teeth. They playfully fought over his load, tongues wrestling as it was passed back-and-forth between them, each compelled to slurp the most down and prove themselves the worthiest mate for this stud. And when the supply ran low, they licked more off each other, most of it swathed over their luscious sets of tits.

He patted their cheeks with his dick, offered a few playful yet dominant slaps. “Clean my cock and balls,” he ordered and with faces twisted in sheer lust they lapped at him. “Good girls,” he all but nickered, stroking their scalps. They cooed in appreciation; and as slivers of sanity started to return to him he pondered if their experiment had worked too well?

Yet they had given the reigns over to him entirely, begged him for more as estrus-like effects left their thighs absolutely soaked, and the beast now inside the normally gentle boy demanded it be sated. “Form a pile with your asses towards me, largest on the bottom.” They snapped to obey, Sunset prostrating herself on all fours to be mounted. Twilight swung a leg over her, similarly perched on top, and lastly Wallflower clambered to the top of this fleshy naked tower, cooing with them to be fucked stupid.

Grunting he sank his horsecock into Sunset's pussy with a wet squelch. Her eyes went wide with a whinny-like moan, on the verge of instantly creaming herself, so long had she been without a stud buried deep inside her. She squeezed down on his dick, milking it, coating her slimy pink walls with his precum. She simulated a nicker, nostrils flaring to be taken roughly.

Above her, the girls dribbled down each other, Wallflower's feminine lubricant washing over Twilight's puckered asshole and cunt, mixing with her natural lube as it painted Sunset's fuckholes and his equipment. He teased her with slow strokes that made her whimper in need, pressed his flare against her cervix repeatedly. “D-don't tease me,” she begged.

A loud smack on her ass made it wobble and her yelp; a reminder he was in charge! “Wait your turn, bitches.” He withdrew from her birth canal which pressed down in attempt to keep him in, sending spatters of her juices about that still connected her to his meat when he withdrew, and he shoved into Twilight's twat, making her moan and snort as she drooled.

After a few strokes he dislodged and skewered Wallflower last; she squeaked and dug her nails into Twilight's breasts. Gradually he took turns fucking them, sometimes for dozens of slams, other times merely a few, testing their limits and keeping them on edge, not allowing them to finish but keeping them worked up and shamelessly pleading to take his cock.

His palms kneaded their tits and buttocks, landed more slaps that echoed through the lab, red hand prints left to mark their asses as his property. The two who weren't currently being pounded he'd tease with twists and pinches of their perky nipples and swollen clits, or he'd shove a couple of fingers up their sphincters and slits, then make them taste their own love nectar.

“P-please,” whined a red-faced Sunset whose eyes were teary with want for blessed release.

She was his alpha bitch, after all. With a violent shove he groaned and pierced into her cervix, bottomed out in her slippery, slime-drenched womb, his flare fully blossoming to lock him inside. The mushroom-like tip pulsed and unloaded its first virile payload, splashing against her confines with such force she wailed and milked him harder, her pussy gushing over his groin. He fired spray-after-spray, emptied the first salvo, her eggs awash in a murky white soup that bloated out her belly.

With a loud pop he withdrew and impaled Twilight, the process repeated until she was left a similar panting mess that soaked his equipment. Removing himself, he took a mere moment to admire their gaping funholes which ran with his seed, then he savaged Wallflower in the same manner, easily the tightest of the three. He filled her uterus to overflow like them, made her shriek and her dam break upon him in a messy deluge, until she was also left a ragged, thoroughly satisfied mess.

They stared back at their stud with sleepy, half-lidded eyes to match dopey expressions, made whorish bestial noises as they reveled in their afterglow. “Spread yourselves open.” Using a couple fingers they fully parted their pink pussies, packed full of gooey cream that partially slid from them. “Now, make a daisy chain and clean each other out.”

His herd did so, making a fleshy circle, eating each other out and rimming their companions for good measure. And after they scooped out every last drop with their tongues they could get a hold of, their wet mouths met and passed the gunk between them, tasting themselves and their pals, swishing the natural cocktail which they slurped and swished and chewed.

After they swallowed down his thick treat a semblance of normalcy returned to them all. Blushing, the four avoided anyone's gaze, yet they still smiled, the moment captured by the drone above. He asked sheepishly, “Is everyone okay? Sorry if I went too far.” He rubbed the back of his neck and stared at his now flaccid junk. “I don't know what came over me.”

“It was wonderful,” admitted Sunset who rubbed circles around her still swollen tummy.

Wallflower nodded, her freckles radiant under her flush. “I'm not sure I can go back to human dick after that.”

“You hear that?” Twilight hopped to her feet and pulled up the girls to pose with him. “I'd say our experiment was a success!” She seized her cellphone off a table and snapped a selfie, to memorialize the moment. They also offered him their bras and panties as trophies; so far as they were concerned he'd earned them, after the most intense bout of sex they'd ever had!
