Sonic the Hedgehog is the fastest runner in Equestria, and Rainbow Dash is Ponyville's aerial ace. When Sonic asks Rainbow Dash out, they come up with a brilliant idea that will change Ponyville forever.

Sonic the Hedgehog was the fastest runner in Equestria; not even Shadow could hold a candle to Sonic's speed. Similarly, nopony in Ponyville can match Rainbow Dash's aerial superiority and grace. When they both found out about each other, they became -quick- friends. Even quicker, they became inseparable lovers. Together, they ruled sky and ground and loved every moment they had in the spotlight, but they wanted some more, something special. And then it hit them: something only they could do that all of Ponyville would remember for the rest of their lives.

Breaking The Speed Barrier

Sonic and Rainbow Dash wanted to be remembered. Not just by Ponyville, but all of Equestria. However, it was easier said than done. They were already known as the fastest pair around, but it wasn't enough. What could they do that would make Equestria remember them until the end of time?

The two were currently at Rainbow Dash's house on her couch. Rainbow Dash had Sonic's little cock positioned in her mouth. They had been maneuvering a little bit, trying to find the best position to give Sonic a blowjob. His penis was much smaller than average, so Rainbow Dash had spread the hedgehog's legs and stuck her head between them, grabbing hold of that perky little hedgehog dick.

"Oh fuck, Rainbow Dash!" The pegasus felt Sonic's gloved hands dig into her back.

"What is it, Sonic?" she mumbled around his cock, but her actions only made her boyfriend buck even more violently.

"AH, AH, I'M... CUUUUUUUUUMMING!!!" screamed Sonic has milky white semen spilled out of his throbbing cock, emptying its contents into Rainbow Dash's mouth. He moaned slightly as he felt Rainbow Dash's lips sliding off his penis head, which was painfully sensitive after his orgasm. The next moment, he felt something warm and sticky spray on his face. Reaching out a hand and rubbing it, he knew exactly what it was. "H-Hey, what was that for!?" he cried. "I just showered before this!"

Rainbow Dash gave him a scathing look, a fire blazing in her dark pink eyes. "What the buck do you expect when you cum before I even have a chance to move my mouth over your penis!?" She huffed heavily. "Are you even taking this seriously? Maybe you can invite Shadow over next time so we can--"

"NO, FUCK NO!" screamed Sonic. "I've regretted doing that from the day I did it!" It was true. Sonic had questioned his sexuality that night and in fact, he still wasn't sure if he was bisexual or not. However, what he did know was that Rainbow Dash was the one for him. The way her pussy fitted around his cock, the perfect blowjobs she gave, that tight and perky ass that swung in his face when she was walking around. He loved all of it, and not even his best friend Sonic could take it from him.

"Fine, whatever." Rainbow Dash looked down and started masturbating furiously since Sonic had cum so fast. She moaned and squirted all over the couch. "Anyway, you got any ideas for what we can do to make everypony remember us?" she asked. "I mean," the pegasus flicked her mane, "I know they'll remember me because I'm awesome. I'm just worried about you," she finished.

"Gee, thanks for that," mumbled Sonic, hanging his head. "I'll be remembered as the hedgehog who sprays cum inside the awesome Rainbow Dash in two seconds flat." And then it hit him. "OH MY GOD, RAINBOW DASH! I KNOW WHAT TO DO!" Sonic sprang to his feet instantly, speeding around the couch to drag Rainbow Dash as well. Her vagina was still sticky and left a clear trail on the cushions as she was pulled to her hooves.

"Oh yeah?" Rainbow Dash massaged her hooves with her temples. her lover had never been known for his brilliant ideas. Not even in his own world. "And what might that be?"

Some time later...

... And that was how they had ended up in the sky, Sonic's body on top of Rainbow Dash's as she flapped her wings furiously. It was one thing to fly by herself, but even Rainbow Dash struggled to fly flat on her back with a hedgehog laying on top of her. "THIS IS YOUR BRILLIANT PLAN, YOU STUPID MOTHERFUCKER?"

Sonic blushed. "I only fucked her once! I was confused at that stage of my life," he said indignantly. "Anyway, I know this will work. Just trust me!" He thrust his hips at Rainbow Dash in reassurance, who gave his erection a tight squeeze in response. "OH FUCK, NOT YET!"

Rainbow Dash rolled her eyes. She didn't believe the plan would work at all. However, she didn't have a better idea either. "Let's just get this over with," said grumbled as she started accelerating in a straight line through the air. She heard a wet squelching noise from below as she barely felt Sonic's micropenis slip inside her perfect pussy. Despite her criticisms of her lover, his penis did feel quite good for the few seconds he got to use it. She had edged for some time before they took to the skies, knowing all too well that Sonic wouldn't last if they started having sex only once they were airborne. So this is it. We're going to perform a Sonic Rainbow Dash Boom and spray our cum all over Ponyville!

The blue hedgehog had began thrusting, panting as he inserted and slid out his blue cock as fast as his hips would let him. Precum was dripping out of the tip and into Rainbow Dash's pussy as they soared through the air. He held on for dear life as he and Rainbow Dash accelerated, getting closer and closer to the speed of sound. He heard his beautiful girlfriend moan first, and then himself as they continued to make sweet love in the sky. "Oooooooh!" moaned Sonic. He could feel it building, like a wave he couldn't control. Closer and closer. And surprisingly, he could tell Rainbow Dash was on the edge right there with him as well. He didn't think he had done that, but he could barely think clearly as his peak approached. There was no going back. "Do it, Rainbow babe!" he shouted.

"A-Ah, got it!" Rainbow Dash fluttered her wings as fast as they could. The atmosphere around the two lovers grew louder and louder until they could barely hear each other moaning at all. "IT'S TIME, SONIC! I'M..."

"CUUUUMMING!!!" Sonic and Rainbow Dash shouted in unison as they orgasmed together in the middle of the Sonic Rainbow Dash Boom. Sonic could feel Rainbow Dash's pussy pulsing around his cock as he also climaxed, ejaculating as far as his cum would go inside his girlfriend's tight cunt.

I'M LOSING MY MIND IT FEELS SO FUCKING AMAZING!" screamed Sonic as he kept thrusting. His penis head was red and throbbing, but he forced his hips to continue, willing another few splurts of semen from his member.

"ME TOO SONIC, THIS FEELS SO FUCKING GOOOOOD!" Rainbow Dash was having multiple orgasms and squirted all voer Sonic's cock. Some of the fluid leaked out, watering the plants and trees that they rapidly passed by.

There was a thunderous crash and a rainbow trail blitzed across the sky, with another milky white stripe on the inner curve under the violet one, and then another semi-clear curve inside that one. It was... beautiful. Ponies began looking up at the rainbow in wonder. It was impossible for rainbows to have more than seven arcs, and yet it was right there above them. A rainbow with nine curves of divine, soul soothing colour.

Princess Celestia flew up immediately at the sight. "Why that's beautiful, Rainbow Dash!" Suddenly, the princess sniffed. "What the fuck is that? Smells like shit," she commented. She got closer and licked the white trail, then the clear one. Her eyes sprang open in recognition, and she gagged in disgust. Celestia would recognize those two tastes anywhere; Shining Armour had introduced her to the taste of semen when Princess Cadence was away with Twilight to watch some magic show back in Ponyville, and she had tasted the clear sweet vaginal fluids of a mare when she seduced Twilight Sparkle when she was mentoring her in her filly years.

In the end, Sonic and Rainbow Dash were caught and sent to Tartarus for the actions.

"Fuck you, Sonic. I am asking shadow next time," Rainbow Dash muttered as she masturbated from inside her cell.
