Metamorphilia

“Wait!” Rainbow shouted as Twilight picked up her die. “I… um… I need to use the little fillies' room.” She fidgeted on her chair, her bat wings ruffling adorably.

Applejack chuckled. “Aren't we a bit beyond that now, sugarcube? If you're that hot to trot then—”

“No, seriously. I drank, like, four bottles of cider just now.”

“Oh,” Applejack said sheepishly. “Right, course.”

Rainbow hopped out of her chair and started for the door.

“We'll wait for you,” Pinkie Pie said as the batpony trotted out of the room.

“Thanks!” Dash called back from out of sight.

The door closed behind her, and the room was plunged into another moment of awkward silence. Twilight shifted on Pinkie's lap, slowly becoming more and more aware of just how blatantly sexual she looked. Legs splayed, hair mussed, her slit dripping and slightly spread from its recent penetration. And then…

“Pinkie, I'm sorry that I, um, did that. Without asking.”

Pinkie let out a languid sigh. “That's okay, Twi. I would have told you to get off if I wanted you to. Or just moved you!” Pinkie Pie reached out with her forelegs, wrapped them around Twilight's middle, and hugged her tightly to her chest, nearly lifting Twilight clear into the air in the process. “Earth ponies are strong, remember! And I'm a big earth pony now.”

“Sure ya are, Pinks. Even as a guy you're pretty dang average for an earth pony.” Then Applejack accidentally glanced down at Pinkie's still semi-erect penis and flushed. “I mean, overall. Your whole body. I don't know enough about stallion bits to really say.”

“I do!” Pinkie said with excitement. “I've seen big ones and little ones and all the ones in between.” When everypony else stared at her, she said, “What? It comes with the party territory. You're all acting like you've never been to an orgy before.”

Glances were exchanged at that, to say the least.

Twilight fluttered her wings and kicked her hindlegs a little. “You can let me go now, Pinkie. I think I'm ready to go back to my chair.” The earth pony loosened her hug, and Twilight hopped over to her seat with a flap of her wings and settled onto the cushion. It was a nice cushion, a cushion suited for royal rumps, but Twilight immediately judged it to be inferior to Pinkie Pie's lap. And, of course, her soaked, cum-filled pussy was absolutely going to ruin the upholstery in a moment.

With her passenger finally disembarked, Pinkie Pie straightened in her chair and peered down between her own legs. “Aw, it's already starting to go down. That's the worst thing about dicks, you know. They get tired way too fast.” She reached down with one hoof and gave her cock a few slow strokes. “Hmm. You're right, Applejack. It is pretty average. I like it though!” Pinkie Pie stood up and trotted away from the table to give her friends a view. Her half-hard cock hung beneath her stomach, a thin line of semen trailing from the tip. “Not bad, right?”

Applejack frowned. “Sure, I guess. If that does it for you.”

“I like it,” Fluttershy whispered. “Um, that is to say, it's… nice that you like it.”

Rarity patted Fluttershy's shoulder gently. “Now, now, no need to be embarrassed, darling. She does look like quite the appealing young stallion.”

The door opened and every single one of them jumped.

Rainbow trotted in and smirked at the room. “Sheesh, it's just me, calm down.” Her coat was back to its usual sky blue, her wings feathered once again. “Let me tell you, getting transformed from one creature to another while you're trying to pee is weird. I don't recommend it.”

“I guess the bathroom is just far enough away from the dice that the spell fell apart. So, if anypony feels an urgent need to change back to normal, that's a good place to go.”

“But again, don't use the toilet until it's finished. Seriously, it's weird.” She pointed a wingtip at Pinkie Pie. “Especially you. I don't even want to think of the mess you'd make if you started with a cock and ended up without one mid-stream.”

Twilight rolled her eyes. “Thanks for being so protective of my guest bathroom, Rainbow.”

“No problem, boss.”

Once Rainbow returned to her seat, Twilight floated the empty bottle over and took a breath. “Remember, it's okay to pass if you're uncomfortable, especially after, um, that.” When everypony nodded, she set the bottle down and flicked it with a hoof.

A moment later, it stopped, pointed directly to the deer.

“Fluttershy,” said Twilight.

The little deer nodded bravely. “O-okay. I'm ready.”

Twilight passed her a die, then grabbed the other one herself. “On three.”

“One.”

“Two.”

“Three.”

Both dice clattered against the crystal table.

Fluttershy's die showed a trio of fluttering feathers, the same result Rainbow had gotten on her very first turn. Instantly, Fluttershy felt the sharpening of every sensation. The scent of sex in the air, the heat radiating off her friends, the texture of the cushion, her own needy nethers. She shuddered in place, butterflies swarming in her stomach in anticipation of what their challenge would be.

Twilight's result was a bit more bombastic. Her die once again landed on the species change symbol. Is this thing rigged, she wondered. But of course it was. This was Discord's game.

Her skin prickled in waves that rolled from her head down to her hooves. She felt her dock growing longer, her tailhairs receding. Little twinges of pain sprouted along her spine as her posture shifted, driving her shoulders up over her hips, straightening the line from her chest to her neck to her head.

The others watched in fascination and horror as the most dramatic change of the night unfolded in front of them. Twilight's coat melted into scales, her legs bent and twisted as her joints wandered and changed orientation. Her hooves split into fearsome claws. Her face stretched out, muzzle extending far past its usual position.

And she grew. With each passing second, less and less of her fit on her chair, until finally the changes stopped and left a vibrant purple dragon perched carefully on her hindlegs, her tail draping off the back, her majestic wings flared behind her, and her arms braced on the table.

Twilight looked around—and down—at her friends. “Wha-what am I?” she asked through an intimidating set of teeth.

“A dragoness,” Rarity said, a bit flushed. “Think of Dragon Lord Ember, but… well, bigger. You'd surely stand head and shoulders over her. Oh, and you're a bit more serpent-like, I think.”

“No fair,” said Rainbow. “I wanted to be a dragon!” She reached over and ran a hoof down Twilight's side, feeling her scales. “It's a shame you can't test out those wings. I bet flying as a dragon is awesome.” Twilight reached out to playfully swat Rainbow's hoof away, and Rainbow darted back. “Whoa, careful! Those claws are no joke.” Indeed, each of Twilight's new fingers ended in a curved claw that was easily long enough to stab halfway through a pony's leg.

Twilight pulled her hand back sheepishly. “Sorry. I'm not used to having sharp bits.” She turned to her partner. “Ready to turn over a card, Fluttershy?”

Fluttershy nodded shakily. “Yes, I'm r-ready.” She bit her lip. “I t-think the feather side makes you really s-sensitive, by the way.”

Applejack arched an eyebrow. “Aren't you always pretty sensitive? No offense or anything.”

“Not that kind of sens—ah—sensitive,” Fluttershy replied with a slight smile. “It's like my whole body is tingly. It's very strange. Not bad, but strange.”

“Sounds like Discord all right,” Twilight muttered. She turned over the card and immediately felt her face burn. “I think the stakes are rising a bit.”

“No kidding,” said Rainbow dryly. “You just used Pinkie's cock like a vibrator and then let her jizz inside you. What could the card possibly say to top that?”

“But that wasn't on my card!” Twilight argued, blushing even harder at Rainbow's words. “I was only supposed to sit on her lap! And you and Rarity weren't supposed to kiss, you were just supposed to bite her neck! This challenge is… well, I'll just read it.” She took a breath. “Eat out your partner for sixty seconds.”

It was a good thing everypony was out of cider, or there would definitely have been spit takes.

Rarity blinked. Applejack hissed through her teeth. Rainbow let out a low whistle. Pinkie Pie's hooves tapped together in glee.

Fluttershy whimpered. She knew—she knew!—that if anypony so much as touched her down there, she'd be finished. A whole minute…

“We can pass,” said Twilight, gently.

Rainbow added, “You're not even into mares, so it's no big deal if you don't want to.”

“No!” Fluttershy shouted. “I mean, um, we're doing so well, I wouldn't want to put a damper on things.”

Once again, Rarity reached over and gave the deer a gentle pat. “If you want Twilight to bury her dragon tongue so deep inside you that you scream, you should say so.”

“Oh my.”

Twilight's heart was pounding as she stood up from her chair and made her way across the table to Fluttershy. Perhaps this wasn't all that scandalous after what she'd done with Pinkie, but that had been a spur of the moment thing, a slippery slope into lewdness that she hadn't seen coming. And, even more importantly, she hadn't thought anypony else would notice at first.

Her claws clicked across the crystal floor with each step. She had a feeling her new form was designed to walk on two legs, but she didn't trust her balance just yet, so she moved on all fours, her wings slightly extended, her long, muscular tail whipping gently behind her. She felt heavy but powerful, a bit like how she'd felt after becoming an alicorn only ten times more so. She danced carefully around the table, worried that so much as leaning on it would shatter its hard crystal surface.

Rainbow Dash's eyes were wide as Twilight walked past her, giving her a wide berth. She was close enough to see the subtle muscles rippling under Twilight's bright purple scales and the light gleaming off the razor sharp spikes along her back. Rainbow was used to ignoring the predatory beaks and claws of griffons, and she'd never had a problem seeing Spike or Smolder as the gentle dragons they were, but she couldn't deny that Twilight's new form was dangerous.

The effect was only slightly ruined by the last of Pinkie's load trickling down Twilight's hindlegs and tail.

Fluttershy turned in her chair and stared up at the approaching dragoness. Apart from her lovely purple eyes, Twilight's face was so different now that it was like looking at a stranger. A stranger who was also an adult dragon with teeth to match. A stranger who was about to go down on her.

“Eep.”

Twilight crouched down so Fluttershy didn't have to peer up at her, then down a bit more. “Just say the word if you want to stop. We won't think any less of you.”

The other mare took a deep breath, then slid her chair back and spread her hindlegs wide, displaying her eager marehood for all to see, lips glistening and slightly parted, revealing a tiny slit of pink. “Be gentle,” she whispered to Twilight.

“Don't worry,” the dragon replied, a bit of a smirk on her face. “I've been told I'm pretty good at this.” Although she'd always used a pony tongue before…

Twilight opened her jaws and let her draconic tongue loll out. She swiped it up over her own lips, and blinked in surprise when she felt the tip graze her nose. She had known dragons had long tongues, but this was ridiculous! It was nearly a foot long, and, after giving the air a few test licks, she seemed able to control every inch of it just as well as her former appendage.

She shifted forward and lowered her face into Fluttershy's lap. A full body shiver ran through the deer, but she didn't move away or close her legs.

Twilight started by rubbing her cheeks against Fluttershy's thighs, savouring the soft deerpelt against her scales. She leaned forward and planted a kiss just above her hips, then trailed downward, leaving little half-kisses in her wake. When she reached the top of Fluttershy's slit she pulled back a little and inhaled deeply through her nose. Twilight didn't understand ponies who disliked the scent of marehood. She found it intoxicating, and it always left her wanting more.

But Fluttershy deserved a bit more time to warm up, so Twilight resisted the urge to dive into the main course.

She parted her jaws and gave Fluttershy's inner thigh a long lick, pausing just beside the top of her pussy, then quickly repeated the motion on her opposite leg. Her second lick was almost imperceptibly lower.

Fluttershy's teeth were clenched and her forehooves hung limply to either side of her as she resisted the impulse to grab Twilight by her dragon horns and force her nose into her crotch. Twilight said she knew what she was doing, and so far she was definitely living up to her word.

She lifted her gaze from the dragon between her legs and looked around at her friends. They seemed only slightly more composed than Fluttershy herself. Applejack's forehooves were moving suspiciously under the table. Rarity's horn was glowing, but she didn't seem to be levitating anything. Both mares were flushed and staring, but only Rarity was actually staring at her and Twilight—and mostly the latter.

Applejack's attention was a bit more fractured. Her eyes would scan over Fluttershy's trembling figure, parted lips, and spread hindlegs. They would travel down to the purple dragon crouched in front of her, with her graceful serpentine figure, down to the tip of her tail and the glimpses she was afforded of what that tail hid. And then, inevitably, her attention would turn just a bit to the right.

Rainbow Dash, in all her prismatic glory, reclined in her seat, almost laying on her back. Her hindlegs were spread wider than Fluttershy's, and one forehoof moved languidly over her pussy, pulling and massaging at her labia one second, rubbing gently at her clit the next. Every time Applejack looked over, it took her longer to look away.

The pegasus was so… at ease! Applejack had a feeling that this was exactly how Rainbow pleasured herself in the privacy of her home, relaxed and unreserved. Without thinking, Applejack leaned out of her chair a bit to get a better angle. She could just about make out every inch of Rainbow's hindquarters, and if she leaned a bit further, she'd be able to see the mare's face, too.

Rainbow noticed the motion from the corner of her eye. She turned to Applejack, noted the flush on the earth pony's cheeks, the constant drift of her eyes away from Rainbow's own. Rainbow never stopped touching herself, her rhythm completely uninterrupted. She grinned, then slid her chair back so Applejack had a better view and returned her own attention to Twilight and Fluttershy.

On the far side of the table, Pinkie was similarly subtle. She sat upright on her chair, her cock fully hard once again and sticking straight out from between her legs. Its tip rested just an inch above the edge of the table, and a growing puddle of clear precum was growing underneath it. She ran a hoof up and down her own length, squeezing and massaging her new organ at a steady pace while she ate up the sight of Twilight's cunnilingual demonstration. She met eyes with Fluttershy across the table, who was staring with wide eyes at her cock. Pinkie winked, silently communicating her interest in introducing the two of them soon.

Fluttershy's eyes widened even further, her cheeks flushed deeper.

That same second, Twilight paused her licking to take a breath. She exhaled a mouthful of hot air right over Fluttershy's pussy right as her lips parted and her clit winked out. The sudden sensation was too much for the little deer.

“Oh, oh, T-Twili— ah!” Fluttershy collapsed back against her chair, hindlegs kicking wildly, her hips flexing up off the chair as her marehood convulsed.

Twilight Sparkle pulled back a bit in surprise, but not before her scaly muzzle was sprayed with a generous helping of marecum. She grinned, licked up the mess with her reptilian tongue, and watched, fascinated, as Fluttershy's orgasm continued. She'd never seen anyone orgasm without being touched before. Fluttershy's crotch was soaked and her vulva was quivering and slightly puffy, clit winking out in time with her heartbeat.

Twilight shifted in place, and thoughtlessly placing a clawed hand on Fluttershy's thigh and squeezing a bit, the tips of her digits digging ever so slightly into the soft flesh.

Fluttershy made a sound between a moan and a whimper, and a fresh spurt of juices trickled from her pussy and rolled down the curve of her ass.

Finally, after what seemed like minutes, the deer started to come down. Her head lolled off the back of her chair, her limbs slumped lifelessly, and every few seconds her hips gave a little jerk as the last of the aftershocks racked her nervous system.

“Oh Celestia,” she breathed. “Is— has it been a minute?”

“Uh, I don't think the minute even started. Twilight never even licked you properly!” Rainbow said. “Trust me, I've got a pretty sweet angle.”

Fluttershy's flushed at the thought of her lifelong friend peering between her hindlegs like that. But then, it was hardly a first. She and Rainbow had had their fair share of fillyhood experiences and experimentations, although those moments dropped off pretty sharply after flight school, and by the time they reunited in Ponyville those days were only foggy memories.

Then the rest of Rainbow's statement registered, and Fluttershy yelped and sat upright. “Hasn't started?” she gasped.

Twilight licked her lips. “Nooope. But if you're not too sensitive—”

“I think I probably—” Fluttershy tried to interject.

“—then I think we should rectify that.”

Twilight waited a moment for Fluttershy to pull away or close her legs. When she did neither, Twilight dove in. She planted a kiss at the base of Fluttershy's vagina, then swiped her tongue up over every inch of her outer lips. She pushed in deeper, trying to fit her whole snout inside. Fluttershy was a bit too tight for that, though, so she settled for pressing her lips to her entrance and driving her tongue as deep inside as she could, teasing out all the spots she knew, then even more: places she could never have reached with a short pony tongue.

Fluttershy's second orgasm slammed into her immediately with even more ferocity than the first. Her hooves curled and she moaned louder than she usually spoke. Her hindlegs closed instinctively, and her ankles crossed behind Twilight's head, locking her in.

Twilight pulled back just enough to slip her tongue out of Fluttershy's pussy and move it up to her clit. With a deftness that amazed even Twilight herself she wrapped her tongue around the winking love button and encircled it completely, then slowly retracted her tongue so that every inch of it slid slowly across the little deer's most sensitive part.

Fluttershy howled, and her upper body lurched forward until she was effectively folded around Twilight's head. The sensations wracking every inch of her, vibrating out from her crotch and rattling every nerve, were too much. There was no thought, no other senses, only pure, almost painful pleasure. With nothing else to cling to, she threw herself into it. She leaned forward and wrapped her forehooves around Twilight's long, snakelike neck and hauled herself to a sitting position. Then, using her leverage against the chair and her hold around her partner, she started to thrust back, humping Twilight's face just like she'd humped so many pillows in the past.

The shift in power was almost instant, and Twilight didn't have a chance to respond. She was suddenly locked in place, Fluttershy's thighs squeezing the side of her head, her forelegs commanding her motions. She could have broken free at any moment, of course. A demure little deer is no match for a fully grown dragoness. But escaping was the last thing on Twilight's mind.

She redoubled her efforts, coiling her tongue to spread Fluttershy's insides, stretching it to touch several spots at once, and while she couldn't reach Fluttershy's clit with her tongue from her current position, she could tell that the soft scales of her brow were doing that work for her.

Fluttershy couldn't tell one orgasm from another. She'd definitely had three at least, and even as she rode the aftershocks of one she felt another swiftly approaching. Usually she'd be completely exhausted by now, or too oversensitive to so much as wipe her marehood dry, but now her oversensitivity never veered into discomfort, probably thanks to Discord's magic. She bucked hard against Twilight's face, almost heedless of the other mare's efforts. Sure, the tongue-work was nice, but all she could focus on was the motion of Twilight's snout as it pushed and pulled at her entrance, the texture of scales sliding against her outer lips, and the grinding of her clit against Twilight's forehead.

Finally, something inside Fluttershy snapped. She jolted and pitched forward, her hindlegs unclasping from around Twilight's neck and her forelegs losing their grip. Her upper body landed on Twilight's head and shoulders, and her crotch slid up Twilight's nose and rested on the bridge of her snout. Like a dragon wearing a backward deer hat.

Her limp legs twitched and her stump of a tail wriggled as the last of her energy escaped her. She hung there, unmoving except for the occasional muscle spasm and the slow heaving of her lungs, for a long moment.

Then Twilight sucked in a long, greedy gasp of air. She reached up and gently removed Fluttershy from her perch and set her back down on the chair, then turned to face the room.

Rainbow Dash burst out laughing. The others were only a bit more composed.

“You, your… your face! Your neck! Holy feathers, it's everywhere!” Rainbow nearly fell out of her seat.

Applejack was breathing in tight, controlled bursts to suppress her chuckles. “Y'all might want a quick shower or something, Twi. It looks like somebody cracked a dozen eggs right above you.”

She glared. “Thanks, everypony, I couldn't tell.” She swiped her tongue in a few quick circles around her face, clearing most of Fluttershy's juices off and slurping them down. Then a towel appeared next to her with a flash of purple magic. She she wiped the rest off and banished the towel again. “Was that a minute?”

Rainbow finally managed to get her laughter under control enough to say, “Barely, but it doesn't look like Fluttershy could take another second.”

“Mmmmm,” Fluttershy uttered, somewhere between a moan and a grunt. She was sprawled in a loose pile on the chair, her hindlegs splayed and her hips propped up to avoid brushing her nethers against anything. Trickles of marecum disappeared into her fur and tail, and a bit was already gathering on the chair.

Rarity cleared her throat. “I think perhaps we should give Fluttershy a rest for a few rounds, hmm?”

“Yeah, I reckon she's a little tuckered out.”

Rainbow leaned over and nudged Applejack in the ribs. “More like 'fuckered out,' right? Right? AJ, right?”

Applejack sighed and silently cursed the beautiful idiot beside her.

Twilight returned to her chair and reached for her glass of cider. Empty, of course. She quickly summoned a pitcher of water for the table and refilled her cup. She took a deep gulp, washing away the remains of her challenge. “All right then. If we're all ready…”

And all eyes turned to the farm pony.

Applejack looked around at the room and saw a dragon, a deer, two tomcolts, and a stallion, and she licked her lips. “Hurry up and pass me a die already.”
