Pinkie Pie was the sort of mare who tried to keep abreast of what everypony was up to. Not that she wanted to be nosy, but she was curious by nature, and strove to make certain her closest friends in particular were always happy. As a consequence she'd ended up spying on Spike's herd, watching it form over time, and doing her best to keep it a secret until they were ready to break the news. It started to drive her crazy as the weeks passed...especially once Rainbow Dash suspected something was up.

She'd done her best to slip away and derail any conversations about what secrets she was keeping, which merely served to frustrate Dash even more, the pegasus often stalking her across Ponyville. Luckily, it wasn't hard to give her the slip despite her speed, due to how surprisingly sneaky she could be. But after hours of evading her even she was starting to get worn out!

The sun bore down on her, Dash having kicked aside all the clouds, leaving the blue sky blank. Ponies were going about their daily routine, ignoring her as she scuttled by, a silhouette always looming behind her. She slid under carts, weaved between mobs, and hopped from place-to-place, trying to keep low so it would be harder for Rainbow to scoop her up.

She started to duck behind Sugarcube Corner, relieved she was almost home...and stumbled upon exactly what she'd tried to avoid. Behind the quaint little shop Spike was busy mounting Rarity, biting her lower lip to halfway silence her moans, the fire ruby on a chain bouncing in tandem with her milky, veiny tits each time he slammed his twin cocks into her. She sucked in a gasp, stunned. Why'd they have to pick this spot of all places to start fucking like wild animals in heat?!

Not that she could blame the attraction; that predatory dominance and sense of danger, knowing that a dragon could end her life at any time, yet realizing Spike would never harm her. Of course the idea of dragons eating ponies was outlawed since Celestia and Luna came to power, but a subconscious realization they were prey remained a genetic memory still passed down.

She spotted Rainbow's shadow closing in from the corner of her eye, and intentionally let herself be spotted to draw her attention away from the couple, making a mad dash away. But where to hide? She decided to seek refuge with one of their friends, and settled on Fluttershy's cottage, since it wasn't too far away, and hopefully Dash wouldn't force her way in?

It didn't take long before she reached her destination. She was about to start hammering on the door, only to spot some movement within, and decided to take a teensy peek into the window. Her eyes shot wide open.

It wasn't a well-kept secret that Fluttershy and Tree Hugger were in a relationship, even though they tried to keep it on the downlow. However, she never expected to see them involved in a foursome with Discord and the Smooze! He was busy reclining and smoking one of Tree's joints, wearing a pair of sunglasses, while the mares happily bounced atop his dicks.

The bundle of slime would roll over their bodies, stimulating them with its odd texture and warmth. The lovers would kiss atop the draconequus, thankful he'd helped them take their relationship to the next level, and so he was now invited around on occasion to participate; his kinkiness was a bit too much for Fluttershy to handle all the time!

Pinkie shook her head with bemusement, wondering if all her friends had gone crazy. Instead of interrupting their joyous session, she took off running again, and rather than try and take refuge in the Castle of Friendship she decided to haul ass all the way to Sweet Apple Acres. Surely an upright mare like Applejack wouldn't be too busy to help a pal out?

She huffed and panted and perspired, racing at top speed to try and beat out Dash. Failing to spot AJ around the trees, in the fields, or about the animal pens, her eyes darted between the house and the barns. Seeing that her pursuer was almost atop her, she instinctively made her choice, rushing into a barn and slamming it behind her.

Sweat beads rolled down her face when her eyes focused. “Oh! Um, hi!” She waved.

Twilight Sparkle and Applejack flushed deep, locked in a passionate embrace while they made out. “Th-this isn't-”

Applejack raised a hoof to hush her partner. “Yep, we're lovers now. Got a problem with that, sugarcube?”

“Not at all! But you know, a lie by omission is still a lie! Still, I suppose it's to protect a friend or two!” Pinkie pressed her ample rump against the door where Dash was currently banging to be let in. “I, uh, kind of stumbled on you two, Spike's, and Rarity's secret some time ago! I haven't told anypony, but I don't think I can keep it hidden from Rainbow Dash any longer!”

“Then I reckon it's about time we told her.” She held her stetson to her freckled bosom. “Go on, let 'er in.”

Twilight wiped cold sweat from her brow, her heart hammering. “A-are you sure? What if she-”

“It'll be fine. Trust me. Rainbow can be juvenile, but she's a loyal friend. I'd stake my reputation on it.” And they very well could be since they hadn't broken the news with many ponies. Not everypony agreed with the herd concept. Some claimed it was sexist or immoral. But with mares outnumbering stallions so badly there were only so many options. “Step aside, Pinkie.”

She reluctantly did as instructed and Dash swept inside, leaving a rainbow trail behind in a blue blur and kicking up bits of straw which rained around them. The pegasus barely pulled to a stop before colliding with a wall. “Hey, what gives?”

Pinkie swallowed, feeling it wasn't her place to explain. “W-well...” She turned to them for support, shrugging.

“I can explain,” said Applejack who took a step forward. “You two know what I herd is, right? 'Course you do. Rarity was in one with Fancy Pants and Fleur de Lis. Well, she decided to start up a little shindig with Spike, invited Twilight here in, and then me once they were good and ready. It might seem queer to some ponies, but we take are relationship seriously.”

“We do have lots of fun though,” admitted Twilight with a bright blush. “I've learned so much about dragons!” She started to recount facts with swelling pride. “For instance, while dragons might be stronger and more long-lived than ponies, they're also far less intelligent on average, and with a much higher mortality rate due to their recklessness! Probably nature's way of ensuring they don't flood the whole of Equestria with swarms of them. Could you imagine that? Oh, sorry! Got carried away!”

Pinkie sat on her haunches swishing her poofy tail about. “No, it's really interesting! Tell us more!”

“W-well,” she continued suddenly feeling self-aware. “Dragons have a pretty stagnant culture since they have little need for technology. They have a very tribalistic, might-makes-right society.” She recalled the way that Ember had practically forced herself on Spike, riling him up until he lost himself to his instincts and ravished her. “And apparently...drake semen is incredibly addictive. It bonds their mates to them whenever they...er...inside them...” She trailed to a whisper, turning beet red.

Pinkie twitched an ear. “What was that?”

“Whenever Spike cums inside them,” stated Rainbow with a barely contained snicker.

AJ rolled her eyes. “No need to be crude, now. It's all from the heart. And we all love each other.” She held Twi in a possessive manner, planting a kiss on her cheek. “If that aint natural, I don't wanna know what is!”

“Ooohhhh,” said Pinkie whose tail swished faster. “Can I join, too? I mean, being a free pony is nice and all, and I like getting lots of action on the side, but maybe it would be nice to settle down too, and I'd like to try it for a while, so-”

“I dunno,” cut in AJ who pursed her lips. “I'm not sure you're a right fit for our herd. Plus, it'll be a bit crowded.”

“Awww....please?” She gave them her best puppy-dog eyes. “I can behave!” In truth it was more curiosity than anything. She'd always wanted a roll in the cupcake batter with Spike but never dared ask him. But seeing him rail a blissful Rarity made her more determined than ever to have a shot at him. “Pretty please? With an unpopped cherry on top? Just one night?”

“Well...I don't mind,” admitted Twi who figured it would at least spice things up. “All of us have to be on board, though.”

“Hmmm,” mused Dash who perched atop a stack of hay. “Maybe I should give your harem a try, too!”

“It aint a harem,” reminded AJ. “It's a herd. We all consider ourselves equals here. Sure, we do our best to please Spike, and Rarity likes callin' the shots outside the bedroom most of the time, but we each have a day with him all to ourselves if we want each week. Okay, maybe we do kinda play the role of his fluffers while the chosen mare takes her turn...”

“That's hot.” Dash's imagination was on fire at what the herd got up to in private. She lazily stretched her wings. “What do you say, Applejack? Afraid Spike'll trade up for me once he tastes the rainbow?” She shot her the cockiest smirk she could muster.

“Fine. If Rarity and Spike are okay with it, ya'll can have a night with him. 'Course, you don't mind sharin', do ya?”

“Nah, that's fine. Just hope he can handle the most awesome mare in Equestria! Oh, and the funniest, too!” She pulled Pinkie close with a wing, already thinking up all the things she could potentially try with Spike. Sure, she'd had a few flings with lots of potential paramours; a number of the Wonderbolts, Gilda, Quibble Pants, Daring Do (At least in her dreams!), but she'd never been able to settle down. Heck, she and Pie had even had a few romps in their time, usually when they were piss drunk.

For her part Pinkie had to try hard not to bounce all over the barnyard walls. Not having to keep this a secret anymore was relief enough, but a night of fun with Spike? It was almost too much to wish for! Of course she wasn't certain whether they'd all agree to it, but her heart was set on it anyhow. A shame Fluttershy would be left out, but it's unlikely she'd ever go for it regardless. At best maybe she could convince her, Tree Hugger, Discord, and the Smooze to let her in own their sessions?

The mares decided to go their separate ways in preparation for what was to come.

*****

Becoming bolder as her sex life became kinkier, Fluttershy still insisted they kept their relationship private, but after a naughty suggestion from Discord, and Tree Hugger shrugging in a why not sort of way she decided to take up his offer, too. She and Hugs stood in her cottage before a full-length mirror in her bedroom, and she exhaled sharply in anticipation. The Smooze watched from one side, what passed for his head tilted, while Angel Bunny thumped his furry paw with a glare.

The draconiquus had transformed himself into a pair of insertable plugs topped with shiny jewels. It was a risque sort of fashion statement, usually reserved for underground cultures on the wilder sides, and far beyond a similar bit of fetish wear like a saddle Rarity had taken to wearing. With a flush she and Hugs inserted the buttplugs into each other's plotholes, and she moaned low when it sunk in, her sphincter reflexively constricting around the piece once it filled her warm tunnel.

Tree Hugger smacked her lover's rump which wobbled under the impact. “That's a nice look for you, babe.”

“Th-thanks.” It was strange enough to stick Discord in such an intimate place, but to go out in public like this? She could feel him occasionally wiggle inside her, making her nethers leak down her loins. “Don't tease me like that, Discord!”

“Ah, but where would be the fun in that?” His chuckles sounded from their rears, making her redder. “Ready to hit Ponyville?”

“Um...okay.” Fluttershy sat on her haunches and patted the bunny's head. “Don't worry, we'll be back in an hour or two. I've prepared your favorite salad and left it on the table, so try and enjoy yourself, okay?” He nodded, softening.

With a crooked grin Tree Hugger said, “Let's mosey.” The sleepy-eyed hippie lazily took the lead like she often would, leading her love out of the cozy little abode and on the path towards Ponyville. Within a short time they reached their destination, and Shy kept her tail firmly tucked down over her privates, while in contrast Hugs hiked hers up a bit in a daring manner.

It was normal for ponies to wander around nude, but clothes had a manner of drawing attention to their usually innocent bodies, sexualizing them, and doubly so in the case of fetish-wear like a buttplug. But the idea it was a sentient creature on top of that? She could only imagine the scandal, and felt her lower holes clench in response, the taboo nature of it all leaving her lower half drenched. She darted her eyes about as her heart raced, swearing the ponies she passed could smell her musk.

Her limbs trembled and she huffed, her barrel rising and falling, until Hugs steadied her. “Easy now, babe.” She stroked her love's pink mane. “You're like, doing totally great, you know? I'm really proud of you for stepping outside your comfort zone.”

(Yes my dear Fluttershy,) telepathically spoke Discord into their heads. (You've been most accommodating! But how about we kick this up a notch to make it more interesting, hmm?) He transformed himself into a second pair of plugs...much larger ones which were embedded deep within their snug pussies, soaking in the warmth and moisture of their hot pink love tunnels.

Tree Hugger's sleepy eyes rolled into her head as she opened her maw to cry out a silence orgasm from suddenly being so thoroughly filled, and she barely managed to clasp a hoof over Fluttershy's mouth, whose dam similarly broke as she gushed with her, only she couldn't restrain her blissful shriek which Hugs could barely muffle. Shy's wings shot out, fully erect.

Not that Discord let up even when they were about to crumble, enjoying the way he could blissfully torture the pair, playing with their most intimate parts hidden from view to the populace. They were barely able to maintain even a lazy gait, and were forced to excuse themselves from the crowded streets, given odd looks from the unaware citizens who passed and assumed they were under the weather. That was until he caused their docks to raise, fully lifting their tails and exposing them to a stunned audience still nearby. His almost insane sounding cackles echoed in their skulls, unable to control himself any longer.

“D-Discord,” cried a stunned Fluttershy who whined in a feminine manner.

“Whoa,” mused Tree Hugger in a more laid-back fashion. “Trippy.”

“Sorry, couldn't resist!” Sure, he'd mellowed out a tad over the years, and had been on his best behavior when Fluttershy and Tree Hugger invited him over, fearing that if he misbehaved he'd miss a chance at such hot pieces of ass, but he'd managed to restrain most of his impulses. He still couldn't resist torturing Angel Bunny when they weren't looking, though!

In truth he could easily make proxies of the pair and have them any time he liked; but it just wouldn't be the same. Thus he'd restrained himself in the hope he'd get a shot at Fluttershy for real one day, and his patience had finally paid off.

On the other hand he he'd once made a temporary copy of Tree Hugger when he thought she'd stolen his friend away, summoned up a few copies of himself, and hatefucked the absolute shit out of her, calling her every degrading thing he could think up to vent his frustration. That memory often helped whenever he needed to get off hastily.

He'd finally grown a little fond of her, at least. However, he decided it best to keep what he'd done a secret! She'd probably chuckle in a way he once would've thought was mocking him and shrugged it off, but he tried not to show his pettier side to Fluttershy when he could help it. Sometimes he almost felt like another one of her tamed animals!

The pair stumbled down an empty side street, taking refuge in the shadows away from prying eyes. Tree's eyes looked even sleepier than usual, while Fluttershy panted, unable to stop thinking about how what happened would be burned into the brains of the witnesses. She couldn't deny how hard her marehood was winking, though. Why did this all turn her on so much?!

Unable to contain her hunger any longer, Tree Hugger lifted the pegasus up and practically slammed her into a wall, locking lips with her in a sloppy manner. Shy wrapped her limbs and wings around her as their tongues danced, nibbling on each other's mouths. “Oh Tree,” she whimpered between kisses, trails of sticky saliva strings still connecting the worked-up couple.

Not be be left out, Discord moved within their slippery walls, rocking them to the core. They clenched down their holes in response, focused entirely on one-another, not that he minded being their toy with all the interesting and fun times they provided! He massaged their wet interiors, even able to see, smell, and taste them on a whim even in this guise.

Tree almost knocked the wind from her lover when she pounced atop her, pinning her below as they continued to make out. Their limbs wrapped around each other, pressed barrel-to-barrel, their tits smooshing as their erect nipples caressed and danced. Wanting to push this even further, Discord mutated the plugs inside their holes once more, transforming them into a pair of dildos that connected them. But these were no ordinary toys, not only resembling a pair of horsecocks that ended in flared heads at both tips, but they felt exactly like the fleshy protrusions too, veiny and pliable as they swirled within their warm loveholes.

Hugs seized Shy's ankles on her backhooves, lifting them up and pulling them back until they surrounded the pegasi's head, angling herself to drive in deep as she could manage, bottoming out once his flared tips hit their cervices. “I-I want to be fucked by a tree,” cried Shy nonsensically as her eyes glazed and her mind was doped up by bliss. Normally Hugs wouldn't be so rough and domineering, but something about Discord's presence seemed to bring out all the things they tried to repress within them.

She smacked atop her, ass-to-ass, breasts-to-breasts, and pussy-to-pussy, small translucent spurts erupting from their marehoods each time which squished with schlick sounds. He massaged their spongy g-spots with surgical precision. Swollen, glistening lovebuds kissed and danced, throbbing as they rubbed into each other, making their snatches continually leak.

Within mere moments they squealed and came as one, well attuned to one-another by now, almost of one mind, body, and soul when they lost themselves in their passions due to the meditative sessions they undertook together. Their cunts winked and constricted with their assholes repeatedly with each full body spasm, like a bunch of vices around the wetted cocks.

He throbbed and spurted inside of them, painting the insides of their fuckholes, increasing the heat and volume of his seed to impossible and almost absurd levels. Their wombs swelled until their bellies distended, to the point where Fluttershy feared they'd pop, the mares pushed once more over the edge by the sheer force on their unmentionables, making them squeal and squirm. He refused to let up until he was certainly they couldn't take any more, fearing he'd permanently break them. Sure, Tree Hugger had obviously been around some, but compared to a kinky creature like him she was still an amateur.

The couple collapsed unconscious, and the pair of double-headed dicks plopped loose with an audible plop, their gaping holes oozing bathfuls of cum which continued to churn, slosh, and bubble within them, their eggs swimming within his dense milk. He transmuted back into his usual self, laughing and smacking their cutie marks, which made their plush asses jiggle about.

“Another pair of satisfied customers!” He bowed to an invisible crowd that clapped and cheered. “No, no, don't thank me all at once! I couldn't have done it without my lovely assistants!” He produced a camera from nowhere, zoomed in on their most intimate parts, and snapped a bunch of pictures with a blinding flash. “Ah, but what to do now?” With a snap he teleported the sopping, cum-drenched mares back to their shared bed in the cottage, certain the Smooze and Angel could look after them.

They'd fulfilled him for the moment. But he wanted more! Much more. He sneaked a peek at the mares that passed, their privates casually on display, usually on all fours like they were always ready to be mounted by any stallion that passed. So far as he was concerned they were practically asking for it! Not that he dared share that opinion aloud.

He pulled up a number of windows in midair to spy on the happening's around Ponyville, going back to Spike's herd with a chuckle, a mixture of arousal and envy swelling within him. A devious idea started to form in his mind...
