"Uhh, Pinkie? Are you sure this is what we're supposed to do?" Rainbow Dash asked. Pinkie was leading Gilda and her up on a makeshift stage that had been quickly set up in town square. Mares and stallions alike were already setting up benches, many of them wearing eager faces and cocky smirks.

"Of course! Whenever somepony challenges your sexual prowess, the only way to settle it is with a Dirty Duel! It's an ancient griffon tradition." Pinkie explained.

"Wait, wait, if it's an ancient griffon tradition, how come I've never heard of it?" Gilda said.

"I agree," Twilight Sparkle said, approaching the group from the other side of the stage. "I've been looking through my history books all afternoon, and I haven't found any mention of a 'Dirty Duel.' Are you sure you didn't make it up?"

"Are you sure you were looking in the right books?" Pinkie answered.

Mayor Mare now joined the rest of the ponies on stage, and Twilight gave a sigh of relief. "Oh, thank goodness you're here, Mayor. This event can't go on. The amount of indecency laws it would be breaking alone-"

"Oh, but Twilight, we wouldn't want to trample on griffon tradition, would we?" the Mayor returned. "Pinkie Pie was so generous as to take me right to the source text to make sure we got every detail of the competition correct. And, after your friends' blunder in failing to recover the Idol of Boreas under your leadership, Princess, we could certainly use the chance to prove to Griffonstone that Equestria is very pro-griffon, wouldn't you agree? When Gilda returns home and tells her people about her experiences, don't you think they'll be impressed?"

"Uhh sure..." Twilight was caught off guard. "But you set this all up by following instructions in a book? That Pinkie Pie showed you?"

"Oh, yes. It was a fascinating read, if I do say so myself," the Mayor answered.

"You wouldn't happen to be able to loan me your copy, then, Pinkie, would you? Or at least tell me the title?" Twilight fished.

"It's like, in every library ever, Twilight! I'm surprised you haven't read it yet. Not too fond of griffon history, eh?"

"It's not that- well, I guess I'll just go double-check myself, then..." Twilight said as she left the stage, feeling like she was having a nightmare.

"Okie dokie lokie, because we've got a Dirty Duel to get on with!" Pinkie hollered to the modestly-sized crowd, who cheered back at her.

"So what are the rules of this thing?" Rainbow Dash whispered to Gilda.

"I have no idea, but it doesn't sound good," she answered.

"Ladies and gentlecolts!" Mayor Mare began to address the crowd. "I would like to welcome you to Ponyville's first Dirty Duel! On this day we celebrate a timeless artifact of griffon history, and remind ourselves about the rich culture of our feathered friends. It is my hope that by watching this elaborate performance of strength and grace, that you will come to a deeper understanding of the world griffons come from, and help Ponyville lead Equestria in griffon/equine relations." She paused to let the crowd applaud for a moment. "Pinkie Pie will be our appointed Master of Ceremonies and referee for the competition. So without further ado, please proceed with the Duel, Pinkie!"

Rainbow Dash and Gilda exchanged suspicious looks, but Pinkie came between them, wrapping her arms around their necks. "Alright, ladies, listen up! We're going classic Grover rules: females only, no scratching or mane-pulling. Loser becomes the winner's slave for a moon. The first round is all about pure skill. You're gonna take turns eating each other out while the referee, that's me, keeps time. The receiver chooses whatever position they get to be in, no talons or hooves, and no mouth above the nipples. Whoever takes the longest to cum wins the first round!"

"Wait, wait," Rainbow Dash put a hoof on her pink friend's chest. "You mean, eat each other out in front of everypony?"

"Yep!" Pinkie answered cheerfully. "The Dirty Duel was a beloved competition for griffons, the ultimate contest of honor, skill, and willpower. Entire cities used to watch lords and ladies duel, and the winner would make their new servant bring them meals at the victory feast."

"Yeah, that's humiliating," Rainbow Dash said. "There's no way I'm doing this."

"What's the matter, Dash? Chicken?" Gilda shot at her.

Rainbow Dash was taken aback, but she saw a fierce mettle in Gilda's eyes. Even if it was stupid, even if it was humiliating, if Dash backed out first, Gilda would bring it up for the rest of forever about how she "wasn't mare enough to take her on in that duel." And Rainbow Dash was anything but a coward.

She scoffed at Gilda. "Speak for yourself, pigeon."

Gilda puffed up like she was about to tear Rainbow's eyes out, but Pinkie Pie came between them again. "Coin toss to see who goes first."

Gilda won. "You go first, Dash. This beak's gonna make you scream."

Rainbow Dash nodded. "Rainbow Dash, take your position," Pinkie prompted. Already, her competitive mind was strategizing, figuring out what position might best help her hold out against Gilda. She figured that her beak might make things difficult, so she opted to simply bend down, putting her clit on the bottom side of her torso. That way, Gilda's longer upper bill would get in the way.

"Alright girls, are you ready?" Rainbow looked behind her, past her raised rump to exchange a steely nod with Gilda. She gulped when she turned to face forward, catching all the eyes of the spectating ponies on her. She felt heat flood her cheeks as her mouth felt suddenly dry. This would be something they would never forget. Rainbow Dash would forever be known as the mare who fucked a griffon onstage in town square. But it was too late to back down now, especially if it meant losing to Gilda. The only way this would be worth the reputation would be to win. She didn't have another choice. The look on Gilda's face when she beat her would justify everything.

Pinkie's voice drowned out her thoughts. "May the baddest bitch win! On your marks! Get set! FUCK!"

Before she knew it, she was raising her tail, exposing her taut ass and marehood to everypony present. She exhaled, steadying her nerves. It would be worth the bragging rights.

"Ahh!" her head shot up as she moaned. Gilda shoved her beak into her nethers, but all she felt was tongue. Not on her clit, not yet at least, but that pointed griffon tongue was exploring every inch of her folds, inside her slot and out. It had been a while since Rainbow had rolled in the hay with a pony, and the attention was something she hadn't realized she'd been needing for so long.

Dash knew that any competition was all a mind game, though. If she could break Gilda's focus and hold her own when her turn came, she could win this round easy. "Enjoying yourself back there Gilda?" she taunted, looking back at her opponent.

Just as Rainbow Dash hoped, Gilda paused to return the taunt, her face like a soldier's in the heat of battle. "I should ask you. You're already soaking wet, Dash," the griffon answered, wiping her beak on her talons for emphasis before diving back in.

Rainbow bit her lip as her marehood was assaulted by that hot, probing tongue again. "Oh please," she huffed, "After this I bet you'll be begging me for another taste of this pussy."

Whether it was Gilda's saliva or Dash's own wetness, the pegasus didn't know, but she could feel that Gilda was right. Her cheeks and even the tops of her thighs were feeling extra cool as the breeze rolled over them. Dash would have tried another taunt, but it was all she could do not to moan with an incredible heat spreading through her groin. How Gilda managed to keep her beak out of the way, she had no idea, but she was getting nothing but tongue, and in all the right places.

Her eyes widened when that tongue took its first swipe over her clit. "Ah!" she hissed against her will. But as soon as the electric sensation had finished radiating throughout her lower body, it was gone as Gilda moved back to lapping over the outside of her pussy lips. Gilda was going with a slower approach, taking the time to warm Rainbow Dash up properly like it was a first date, and Rainbow knew that even if Gilda had laid off for a moment, the break wasn't going to last long.

Rainbow Dash could feel the heat of the audience's eyes on her body as well. She glanced at them, seeing stallions resisting the urge to pump their erect cocks and mares elbowing their friends and laughing at the looks on Rainbow's face. It was one thing to be a spectacle for the town, but it was another thing to think about all those stallions imagining themselves having their way with her when they were alone. And it was an entirely different thing realizing that after this she would have the reputation of a slut among her fellow mares, no matter what Twilight or anypony else did to combat it.

It didn't matter if she was the Element of Loyalty before. It didn't matter if she had been a top competitor in the Equestria games. She wasn't a hero to these ponies anymore. Her moans and blushes, her flanks and marehood, her wetness and eventual orgasm were simply entertainment to the audience. Rainbow Dash was entertainment now.

"Fuck!" Rainbow screamed. She felt the beak now, and Gilda was sliding it into her marehood, her tongue swirling around her clit all the while. After it was a couple of inches in, Gilda pulled back only to thrust forward again. She was fucking Rainbow Dash with her beak! And between the rough edges of the beak and soft, wet teasing of the tongue, Rainbow Dash didn't stand a chance of holding in her cry.

Cheers sounded behind them, and Rainbow Dash didn't know if they were cheering for Gilda or for her. They probably were just cheering for the action, she realized. This was better than any porn they could find in magazines, and as much as that thought humiliated Rainbow Dash, the attention was having a powerful effect on her. Sweat beaded on her brow, and heat was spreading through her entire abdomen as Gilda worked over every inch of her pussy, inside and out. Dash could swear she had done this before.

Like a diving eagle, Gilda was going in for the kill. It must have been brutal thrusting with her face, but the force of her beak spreading Rainbow Dash's nethers, and the onslaught that was her tongue, lashing at Rainbow's sensitive clit was overwhelming. Rainbow bit her lip just to keep her moans in. But she wasn't a champion for nothing. She had more guts than Gilda could ever dream of, and she wasn't about to go down without a fight.

Dash breathed hard through her nose. The sweat was trickling down her neck, just as her juices were starting to trickle down Gilda's beak and wet her thighs. She clamped her eyes shut, letting the cries of pleasure well up in her throat before dying down. She tensed her belly, trying to keep the heat spreading through her abdomen under control. She even imagined Granny Smith as the one giving her the once-over instead of Gilda. Anything to delay her orgasm. Anything to make Gilda work for it. With some luck, Gilda's mouth might tire before she could even make Rainbow Dash cum.

Rainbow Dash allowed a smirk, as it seemed like that might just be the case. Gilda was lapping up her entire slot in broad strokes, and while surges of pleasure still coursed through her, it wasn't anything cum-threatening. She let a sigh escape. She could handle this.

The tongue withdrew, and Rainbow Dash awaited her concession.

"Ohh!" she barked out as Gilda's beak tweaked one of her nipples, the tongue flicking over the engorged nub. Dash had always prided herself on having nice, full teats for such an athletic mare, and Gilda had been jealous ever since they were teens. But the downside was how damn sensitive they were. With Gilda's skillful swirls of her tongue and firm tugs with her beak, even tending to the rest of her mounds, Rainbow Dash could feel her orgasm building once more. She had been caught with her guard down, and Gilda was capitalizing.

When Gilda licked her way back up Dash's belly, she assaulted the pegasus's clit with renewed vigor, cleaning her marehood of the new wave of fresh juice she had produced. Her tits still buzzed with sensation, and combined with the tongue lashing her bead was enduring, causing her legs to twitch and moans to spill from her lips, Dash knew it wasn't about trying to endure anymore. All she could do was delay the inevitable.

Everything seemed to slip away from her as pleasure built within her body. Her breathing and moans couldn't be held back, and her marehood throbbed and winked, her clit pushing out for Gilda's tongue to circle. Rainbow Dash's eyes rolled upward, her back legs trembling as she tried to stay upright. Her gut tightened, and she made one last attempt to try and hold everything back, clamping her eyes shut, gritting her teeth through her ecstatic groans, but it was no use. She felt the tension building, ready to burst at any moment, and she decided she might as well enjoy it.

"Oh- oh- ah," the noises tumbled from her mouth as Gilda ate out her pussy, her beak shoved deep in her marehood. With a final sharp intake, her clit and lips burning, Rainbow Dash went over the edge. "Aww yeah..." she moaned, grinning wide as her pussy began to clench and surge, juices flowing from her as the fire in her clit spread to the rest of her body in a cool heat, every squeeze of her gut and marehood causing her whole body to jerk. She let the pleasure flood through her, not caring who was watching or what it meant for a few moments, her mind too overwhelmed to care.

"That sounds like cumming to me!" Pinkie Pie exclaimed. Looking at her stopwatch, she read off the time. "Three minutes, ten seconds. Not bad, Gilda!"

Gilda moved around to Rainbow Dash's side, wiping her beak once more, the feathers around it a little stained with mare juice. Still, her grin was cocky. "Dash, you came so fast, you'd think it was like a fantasy of yours or something. You got a crush on me, or do you just like fucking on stage?"

Rainbow felt her jaw clench at the taunt, but she kept her cool. "Oh, please. I had to think about fucking Soarin the whole time just so I could cum from that. Watch and learn." To punctuate, she whipped her tail at Gilda as she passed her.

Before Gilda could pounce on Rainbow, Pinkie took over. "Alright, Gilda, take your position!"

Gilda moved around Dash now, wearing a smug smile. She lied down on her back, resting her head on her arms and spreading her legs, revealing a tight-looking pair of lips, already leaking a clear bead from the thin stripe of pink between them. "I don't really expect you to know what you're doing, Dash, so try not to just dive bomb my clit. And don't be shy about the juice while you're down there. Remember, I like it sloppy!" She barked at Dash like she was ordering a pizza.

Rainbow Dash growled as Pinkie raised her arm. "On your marks! Get set! FUCK!"

Dash lunged at her, quickly burying her muzzle into Gilda's folds. Immediately, her nose was soaked in sticky griffoness fluids. Gilda hadn't been kidding when she told Rainbow Dash not to be shy about her juices; there was a lot of it, thick and hot, each drop seeming to cling to the fur on Dash's nose and slide down her face. Dash went to work cleaning, letting her tongue swipe along every inch of Gilda's snatch, collecting every drop of salty, tangy liquid. She had to admit, the taste was pretty good. It made exploring the tight pussy all the more interesting, but as the sounds of wet tongue sliding through thick fluid filled her ears, she didn't hear a single moan from Gilda.

It was all a mind game, Rainbow reminded herself. Stopping for just a moment, she grinned at Gilda, licking her sticky lips as the strands of juice connected Dash's lips and chin to Gilda's cunt. "Damn, Gilda, I didn't know eating me out turned you on this much. If you like it so much, I might give you another round with my pussy if you ask real nice."

Gilda hardly looked up, still reclining like she was on a beach. "I'm barely even wet, Dash. Quit being such an amateur."

She had to be kidding. But Dash couldn't lose time being surprised. She dove back in, re-wetting her muzzle with fresh fluid as the heat from Gilda's loins washed over her face. Dash knew that Gilda was acting cocky to compensate. It was all a bluff. This juice was a sign of how turned on she was, and Rainbow Dash was going to call her on it.

Slipping up, she found the little nub that was Gilda's clit nestled in the wet folds of her marehood. It wasn't nearly the size of a pony one, but Dash knew it wouldn't matter once she had her lips on it. Pursing her mouth, she planted a fierce kiss on it, sucking the bead in, lashing and swirling at it with her tongue.

"Nnf!" Gilda grunted, and Dash knew how much of the moan Gilda was biting back. She continued, twisting her head and lips around Gilda's clit, flicking and squeezing it with her tongue, even grinding her chin into Gilda's opening to create more pressure on her whole pussy. Sure enough, she felt a new wave of sticky wetness coat her chin and upper neck. She had Gilda right where she wanted her.

Or so she thought. "What did I say about dive bombing me, Dash?" Gilda said from above, her voice almost perfectly even. Dash almost stopped for a moment. "Everything's a race to you, huh?"

Okay, so Gilda hadn't been bluffing. No big deal. Rainbow Dash pulled off her clit to explore lower, probing her depths with her broad tongue, lapping the juice out from the tight inner walls. But Gilda seemed to retain her cool. "You call that sloppy? Quit being a prude, I've had burgers messier than this."

Rainbow Dash didn't know what to do now. Gilda was plenty wet, but she stayed laid back, seemingly nothing Dash did having an effect on her. Dash knew she wasn't an amateur, but Gilda was acting like Dash was her waiter instead of her partner.

She could hear the crowd's anxious murmurs, their snickers and 'ooh's. Rainbow Dash had thought being in the spotlight like this would make Gilda just as nervous as she had been, but the griffon's nerves were hard as steel. Instead, it was Dash who was experiencing another wave of embarrassment and fear. Not only was she fucking in front of the whole town, but she was losing.

No. She couldn't lose. She was Rainbow Dash! The most awesome pony who ever lived! Gilda had to have a weak spot. Dash started with her outer folds, licking over them, occasionally planting kisses, sucks, and licks on her golden-furred thighs. Gilda may have let out an "Mmm," but it was hardly the response Rainbow was looking for.

She moved higher, licking up her belly until she reached the dainty mounds that were Gilda's teats. They weren't Dash's size, but they were large enough for her to circle the soft flesh before latching onto a perky nipple, sucking firmly, flicking it with her tongue.

"You always did have a thing for tits, Dash. This must be a dream come true for you," Gilda taunted once more. Rainbow Dash was getting frustrated, and switched to the other nipple, tugging it hard with her lips, circling rapidly with her tongue. Gilda hardly let out more than a small, pleasured breath.

Rainbow Dash was running out of options, and both she and Gilda seemed to know it. The griffon finally leaned forward to grin smugly at her. "Give it up Dash. Maybe you can save yourself further embarrassment. I'll be sure to tell everypony you were just having an off day."

She gritted her teeth. Rainbow Dash may have been many things, even a public griffoness fucker as of today, but she was not a quitter. With a growl, she dove back down in a last-ditch effort to bring Gilda to climax.

Rainbow Dash plastered Gilda's butthole with her tongue. She absolutely lavished every inch of it, and thanked Celestia it was clean. She could feel just how tight it was as her lips explored it and the tip of her tongue prodded it, seeking to loosen it a little. Taking her friend's soft, plump rear in her hooves, she spread her cheeks to allow better access, and continued the oral assault on Gilda's ass, lapping wildly until every inch of it was wet.

"Ohh, fuck," Gilda groaned loud. Rainbow Dash almost grinned. Jackpot.

She pressed her face harder into Gilda's backside, really trying to force her tongue into that vice-tight ring, licking over her taint and inner cheeks as well. Gilda continued to moan above her, and as Dash thoroughly serviced her rear, she felt sticky strands of mare juice trickle down from above, coating Dash's muzzle and brow in waves. Gilda was one wet griffon, but Dash did a few more laps around her butt, really laying into her asshole, waiting until her entire rear was wet with thick griffoness fluid.

Dash lapped up the tangy juice in one stroke, moving in for the kill. Gilda's folds were practically gushing with arousal, and she was no longer reclining in cocky confidence, but hunched over in tense pleasure. Dash had her right where she want her.

"You want it sloppy?" Dash taunted. "Then I'll give ya sloppy."

She mashed her muzzle into Gilda's cunt, earning a high-pitched cry as she slurped at her sopping pussy. Rainbow Dash didn't lick to clean now, instead using her lips and tongue to spread the juice around. She nibbled and dragged her tongue from snatch to tits and back again, coating every part of Gilda's lower body in her hot fluid, and still ended up with a mouthful herself. But no matter how much she spread the sticky love around, every time she came back, Gilda's pussy had a fresh gob of creamy griffoness femcum for Dash to lap up. With every pass, she let her lips clamp down on Gilda's throbbing clit, each one earning a yelp from the gasping beak above.

Rainbow's face and neck were soaked, the strands running like spider silk from her to Gilda. But she didn't hesitate. She knew Gilda was right on the edge, and she dove in one last time to finish her off.

Diving onto her clit once more, Rainbow Dash sucked and swirled and lavished the bead. But as she did so, she lapped at everything else, rubbing her face in a back-and-forth motion all over Gilda's pussy, pressing in with her tongue and stroking over every last bit of sensitive flesh Gilda had just as much as she worked over her screaming clit.

"Nng! Mmf!" Gilda was hissing above her. Dash didn't let up, knowing her climax was seconds away. She continued her messy cunt eating until she heard that scream.

"Shit! Oh, fuck!" she cried out to the heavens as she started cumming. With her last lick, Dash felt a powerful burst of sticky juice hit her face. She jumped back in surprise, watching Gilda jerk and spasm, strangled moans tearing the air as gouts of fluid shot from her nethers into the air. Gilda was a squirter, and with every clench of her ecstatic body, a stream of her copious cum spurted from her, splattering across the stage and into the audience, dousing the upper bodies of a couple lucky stallions sitting front-row for the action.

After a long while it was over, and a raucous cheer went up for Gilda's gushing climax. Rainbow Dash and Gilda were both sprawled across the stage, trying to hold themselves up as they caught their breath. Their pussies burned and their lips tingled, Gilda's face and Dash's muzzle and neck each coated in each other's juices. All that was left was to see who had won.

"Wowee! We'll make sure to mark that splash zone for you fellas next time, amirite?" Pinkie Pie said, waving with her hooves to get another cheer from the crowd. "Now, for the moment you've all been waiting for. It was a close one, but finishing strong with a time of two minutes and fifty-four seconds, our winner is Rainbow Dash!"

"Yes!" Rainbow roared, her fatigue lifting from her as she rocketed into the sky with spread wings. She took a lap around the crowd, basking in their cheers and applause before stopping in front of a scowling Gilda. "In your face! And you thought you could out-fuck me? Better luck next time, Gilda."

"I wouldn't start the party yet, Rainbow Dash," Pinkie Pie interrupted. "The next round starts tomorrow, and I'd wager Gilda's gonna want her revenge!"

"Next round?" Rainbow Dash said. "What do you mean 'next round?' We gotta do this again?"

"You could always forfeit," Gilda said.

With her blood already pumping, Dash didn't hesitate to get in her face. "What's the matter? Scared to face the champ?"

Gilda shoved her beak into Dash's muzzle. "I'm gonna fuck you so hard you won't be able to fly straight for a month!" she growled.

"Looks like the competition's already heating up! Save it for tomorrow, ladies. This Duel's just getting started!"
