Rainbow Blitz needed vagina.

Okay, he didn't need it, but it would be very nice right now.

The trip to Dash's crib - as calling it a house would have been an insult - was formerly one of an innocent nature. He missed his younger sister, as they had been best friends in their youth until he left to explore the world of music and metal. They got along extremely well as foals, and time hadn't changed that in the least.

It had however changed Dash's sex drive, because boy had she grown hornier since she had finished puberty, and she didn't shut up about sex as a young teenager either. At least back then she kept it to that yellow girl who was shy. Now though...

Now she had grown so bad that she had given him a blowjob to end all blowjobs, and she bathed in his cum like it was the Wonderbolt's compliments.

Not that... he was complaining.

The extended family was part of a long lineage of Scandineighvian pegasi. It only made the famous pegasi hotheadedness even stronger thanks to their inability to plunder and stab things violently. If they couldn't stab enemies, they stabbed each other violently. If they couldn't stab each other violently, then they stabbed each other with sexual objects. If it happened to be a relative every blue moon, then that's why mead had been invented.

Was that why Dash was so close to this Applejack she kept on mentioning in letters and recently? Some attraction to another pony who most likely bucked kin but denied it? Had that subconscious seed been planted in the back of her mind?

He wasn't meant to think of this. He was meant to think of guitar solos and power ballads.

Blitz would however, ask if Applejack was interested in doing both Dash and Blitz at the same time through slowly manipulating Dash in revenge. If Applejack wanted to bring her brother or cousin along, Blitz was happy with it. He'd suck off a dude and bang his sister at the same time. He wasn't picky after what Dash had unlocked inside of him.

And so here he was, two days after having had his sister half rape him and using his face as a cum bucket, thinking about marehood. Dash's marehood.

Not that... he was complaining.

Dash had set the bar really, really high. He just needed to call an ambulance for water once he got to the top of that bar.

The sticky make out session afterwards helped give him the water he needed to not die on the spot. And the half gallon of water he drank afterwards too.

All of this thinking was making him hard. So was the thought of having his member buried inside of her vagina and feeling her cum explode on his groin. If she was that messy without something in her...

Blitz rolled over onto his back, turning off the television in her living room and left to stare at his curved, semi-hard stallionhood. He gave his blue cock a casual stroke with his left wing, feeling the warm penis twitch and drip a line of pre down its length.

They were supposed to have gone to Ponyville to meet her friends two days ago instead of... what they had did instead. They had decided for the better to not go to Ponyville afterwards; recuperate instead, and give each other some room and wonder if they should entirely forget what happened. Sometimes sisters tasted each other, so this was just slightly different!

Yesterday they had returned home to Cloudsdale to talk to their parents about life and what they had been up too. Minus their recent adventure of course.

Their parents had noticed they were nervous, and it was thanks to Dash making up the excuse that they had got plastered last night and went to a club together, only for them to have both slept with a random pony and wake up with little memory of what had happened.

Surprisingly enough, both Firefly and Chromatic Flash laughed off their nervousness, saying they were both impulsive, young, and had high stress lives. They didn't need to worry about it.

Blitz was worrying that if he didn't explode on something of his sister's to simply mark his scent he was going to murder somepony.

His wing tendons curled and stroked up and down the length of his penis with nowhere near the trained technique that Dash had. It wasn't that he couldn't and didn't stroke himself off with his wings: It was just that he couldn't replicate the pulsing pull she had done on him. He needed that badly again right now.

His wing moved up and down his entire length slowly, smearing his cock in the dripping pre that escaped from his stallionhood at the thought of her sucking him off again, or burying himself inside of her and filling her to the brim. He reached down with his right forehoof to idly squeeze his warm blue testicles, applying more pressure on his crotch.

Blitz's wing didn't stop its movement along his sleek blue pole, letting his tickling feathers dance over his shaft, the rounded nubs that ended at the tips of his wings tracing over the growing veins of his dick.

That was it. He needed Dash on him. Now. He wouldn't ask. He wouldn't plead. He'd-

He'd be Soarin', and he'd make her wetter than she had ever been in her entire life.

Blitz rolled himself up onto his hooves and crept silently up the spiral staircase toward her room.

Yes. He'd make her plead to be filled by him. And get some sweet revenge. Literally.

Dash was sleeping on her bed and on her stomach, her muzzle resting on two pillows with a blanket around the front half of her body. She was taking a quick power nap before they were going to go to Ponyville. She had done an intense workout to burn off some steam, and the shower made her a pinch sleepy.

And sleeping like she did exposed her beautiful, tight hindquarters.

His wings spread by the sides of his frame as he did his best to hover quietly in the air, moving his body forward toward her.

He knew she beat him physically on all fronts thanks to the years of martial arts, acrobatics, and high-speed flying that she did. Her hearing and eyesight were legendary. He had to be as stealthy as possible if he was to pull this off.

Oh he'd pull it off alright. And then bury it inside of her until his tight little sister screamed in his eardrum like a fan girl.

And pull it off he did. She didn't detect him as the faintest flutter of his wings carried him directly behind her. He placed his forehoof on her wild, untamed tail and moved it to the side as slowly as possible.

He could see why nearly every mare in Equestria got annoyed when Dash flirted or mentioned her fitness level. They couldn't compete.

Her training had shaved off a good amount of the mare fat on her rump and replaced it with a sickle like firmness that would have deflected most hooves if they punched her there. Despite being on the smaller side of pegasi, her lean withers showed incredible strength and stamina. He knew full well she could kick harder than him, and knew that her fit plot truly did deserve the head turns that it got when she decided to flaunt it.

And it was his now.

With her tail free, his eyes focused right on her marehood, and his tongue got the better of him, reaching out to drag his drooling, wet spittle up her blue outer lips.

Dash wasn't a virgin nor a whorse, but she could very well attempt to pass off as the former, and she'd succeed.

Her blue labia lips were a trim, rigid line that curved between her thigh tendons like a racetrack. Biology and the gym had pressed her muscles together and made them the smoothest looking vagina that Blitz had ever seen. The lick of his tongue straight up the middle of them made them faintly twitch, only confirming to his mind that it wasn't an illusion.

There was no doubt ten percent of stallions would not fit in her at all, and another fifteen percent would be downright agony for her. Luckily, he fell smack dab just above the average of pegasi colts. And even more luckily for her - as she had found out - he was on the higher end of the sperm count.

Sperm. Sleipnir he was going to bucking fill her with it.

His tongue moved from the top of her marehood straight down her folds to just above her clit, licking her like a salt lick over and over. His saliva stuck to her flexing muscles as he tasted her sex, and was soon enough rewarded with her pink insides beginning to expose themselves.

And her delicious nectar.

Two days before, after he had recovered enough to breathe, they had decided the least they could do was start with the steps that usually preceded sex. He had no qualms licking up his own jizzum, much like she had no issues with suckling on his neck and cheeks to lap back down her slightly sweet cum.

Getting it straight from the source was heaven.

Blitz had to control himself with all of his might not to grope her rump as his lips tilted to seal around her vagina, pulling on Dash's winking folds to feel them curve toward his snout. His thick tongue flickered across them more rapidly to feel the heat of her opening insides ooze her Skittle hinted honey on his tongue and snout tip. It melted on his tongue, caking it in a soul relaxing flavor that was sinful.

"Mmm... Soarin'. Keep... keep on doing that. Eat as much as you want, stud."

Blitz smiled as his sister rumbled in her sedated half sleep. It seemed that she already thought he was her number one idol and clop icon. It was fine by him. It also gave him permission to fondle her.

He landed on the bed and laid himself down on his side, secretly delighting that his hard shaft was making a tiny puddle of pre that stained her mattress. Good. It would only make his scent known and make her beg for him to continue.

Blitz's forehooves squeezed Dash's rump cheeks and he was rewarded with exactly what he had expected. Dash nickered contently as he began to dig his hooves into the tight muscles and curved form of her withers, his snout fully pressing to her vagina to drink from her body as she showed her approval.

His muzzle and lips pulled and pushed on her open marehood, suckling around the curves of her labia only to kiss her inner pink lips now exposed to him. His snout moved slowly in a circle as he worked, ending with his muzzle directly between her dripping walls that caked his tongue in her cum.

"Buck yes," Dash huffed, her forehooves squeezing her pillow tightly as she arched her back into the pleasure. Her tail lifted straight up into the air at the curling arousal budding through her body. "You have any idea how long I've wanted you inside of me, Soarin'?"

Blitz pulled his snout away from Dash's nethers to lick his lips loudly. He might as well attempt to play the part.

"I just want a little taste of our future star," he smiled, squeezing her rump once more. His lips and tongue slithered down her slit, lapping up the cum she offered him. "And I need to see if you can... uhh... 'handle' what might happen in the after parties."

Dash's wings spread by the sides of her body with a loud pomf of her feathers spreading, her mind reeling at the thought of wild parties with her idol. "Oh man," she panted, "I'm sure you have wicked parties when tours end and stuff. Mmmph. They have to make up for the boring formal ones."

Blitz grinned widely to himself as his lips sealed around her aroused clitoris, giving it a soft suckle. He just had to show her how fun those parties were, and what better party could Dash have than her idol caking her clit in hot saliva and his thick tongue?

By the howling moan that escaped from Dash's muzzle, not much.

Blitz continued to rotate his tongue around her exposed marebell, his eyes watching her sticky fluids pour out of her vagina to the point that it broke his ability to concentrate.

He was going inside of her. Now. Dash was his mare.

Grabbing hold of her rump once again, Blitz sat up on his hindquarters, his pre covered cock erect and needing Dash's soaked pussy squeezing his member for his cum. Digging into her plot as if it was the only thing that was keeping him from falling off of a cliff, he lifted up her rump and pulled her toward him, sliding himself into her.

It felt like his crotch had entered paradise.

He was thankful she had burst his load two days ago, otherwise he would have came immediately with her walls hugging his tower like he dug into her rump cheeks. Deep, loud hisses escaped from his muzzle as his shaft was bombarded by a flood of her warmth and her contracting marehood pleading for his cream. By the content grunts that came out of Dash's snout, she clearly was enjoying it as much as he was.

"Buck you are tight," Blitz huffed, his body shivering as her juices lathered his already soaked shaft in her quam. "Oh buck, can you stop pulling on me like that! I want to feel you without going just yet!"

Dash whickered in sedation, her tail slapping the side of his frame. She was awake, and having the greatest day of her life.

"Mmm. Am I too much for ya, Soarin'? You're grabbing my butt like a friggin life jacket. Man, you must be getting old, or just haven't had the hottest mare in Equestria yet."

That touched a nerve on Blitz. So his mare wanted a fight huh?

Blitz moved his left forehoof from her rump to directly under her frame, using the advantage of having her rear end lifted several inches off of the ground. He did what any angry but loving colt would to his stable mare: He pressed his forehoof right against her clitoris and rubbed. He rubbed her fast and firmly, using her own lube against her.

"Rainbow Dash, don't you want to be on the team?" Blitz purred, his grin growing at the quick scream Dash made in overloading pleasure. "And insulting me? What do you say?"

Dash's tail smacked against his side as she gasped for air. Blitz pulled his forehoof away to give her a few seconds to breathe, only to return to rubbing her marehood tip off to another feminine howl of sexual delight.

"What do you say?" Blitz said, slapping his groin into her rump as the soft squish of their soaked crotches colliding echoed in the air. He pushed his member through her loosening walls, grunting in brute pleasure as his pre squirted inside of her.

"Buck me, Soarin'!" Dash wailed, her eyes wide open as saliva dripped from her mouth. "I'm yours! I'm sorry! I'll be good! Or bad! Whatever you want!"

Blitz pulled himself out of Dash's slit to rub his crotch across her right cheek, staining it with her own juices and his pre leaking down her tight behind. He felt like he had just performed in front of tens of thousands of ponies, and felt like he had made it to the big leagues.

"Good stable mare," Blitz rumbled, pushing and pulling Dash's rump cheeks together as if he was kneading bread. He sat there to regain his own composure, now keen on torturing Dash instead of dumping his cum into her womb. Simply hearing her purr like a cat and pant like a dog at the same time was a treat that he would savor until the day he died.

"Do you want to kiss me?" Blitz asked, sliding his forehooves over her cutie mark. "And will you try to at least not milk my dick like a machine?"

"Anything to kiss you, Soarin'," Dash said, incoherent words of bliss echoing out of her muzzle afterwards. "I'll be a good mare. Just don't tell anypony outside of the Wonderbolts."

Blitz smiled as he pressed his forehooves into Dash's sides, turning her around to stare down at her with a happy, proud grin. "I won't tell anypony."

Before Dash could respond to his words Blitz pulled Dash up and into his lap, content to listen to her squeak once again at being moved without her consent. Feeling her thick and fluffy coat on his own was divine, and now face to face with her, he lifted her up once again to slide his curved shaft inside of her marehood. The wet suckling sound of their drenched sexes connecting was just an added bonus to her loosening up to let him feel her raw heat radiate over his own throbbing dick, returning the favor in kind.

Dash spoke drooling gibberish as her magenta eyes looked into Blitz's own. Her inner walls relaxed to let him breathe inside of her, but the messy slop of both of their lubrication rubbing together between their groins was ecstasy for her. She rubbed herself into his crotch on instinct, Blitz returning the favor with his wings curling forward to wrap around her rump, giving her already slightly ruby behind a dense squeeze.

She tried to speak again, her forehooves stroking down his sides as she looked at him, attempting to restart her brain. She dripped spittle down her chin as her own wings were rigid behind her back, lost to his slow thrusting inside of her sex.

"You're... you're not Soarin'," she sighed, her eyes rolling toward the back of her muzzle as she rocked her hips into his smooth and gentle humping of her frame.

"And you won't care by the end of this," Blitz hissed between his teeth, his wing tips latching onto her rump to reinforce his statement.

Dash opened her mouth to protest, but was silenced when his lips connected with her own, forcing Dash to feel Blitz's tongue merge with hers as he thrusted himself inside of her marehood. It was only made worse for Dash when Blitz readjusted his grip on her rump, pressing and pushing the longest nub on his right wing into her tailhole.

Blitz opened his eyes once the kiss was broken to listen to Dash neigh in lust as he sank his wing tip into her pucker, using it as a feathered anal dildo for Dash to press her weight down on.

"Oh, Blitz, buck yes!" Dash yelled, wrapping her forehooves around his upper back. She tenderly massaged her hoof tips into the base of his wings as her muzzle pressed into his neck, her stomach deep exhales blowing down his chest. "I just... I just... oh my gosh!"

He tried to respond verbally himself, but he couldn't. His wing tip wiggled gently inside of her tailhole as he held onto her rump for dear life, feeling her bear her weight down on his wing. The loud slaps of their fluid covered crotches slamming together filled the air while they exchanged lube. His thrusts inside of her picked up speed on a will far more base than his lust while Dash dug into his shoulders, his need to explode inside of her reaching a breaking point.

Dash broke. Hard.

She let out a sharp cry of pleasure as she simply hugged Blitz, wrapping her lean thighs around his waist to squeeze him inside of her. The feeling of his wing inside of her behind and his shaft sliding inside of her was too much.

Thick, sticky gushes of her Skittle sugar poured down his shaft like a waterfall parting across a rock. She soaked his shaft, testicles, crotch, and their inner thighs in her mare gunk as she tugged on his penis internally as hard as she could. She wanted his cum in her womb, and he delivered.

Blitz groaned in release, emptying himself inside of Dash in an orgasm even better than the one he had before. His hips rolled up and down to slide his rigid member across her grabbing folds, feeding on their mutual desire and longing for a soul purging orgasm.

Hot, pulsating, spurting gushes of his sperm rocketed out of his body and into Dash's own, caking her womb and insides with his foal batter as they moved their hips together to milk each other dry. His penis did everything it could to feel one more contraction of Dash's sex. One more pull on his flared head that gushed his gooey jizzum.

But eventually, neither of them had anything more to give. They breathed, moaned, and whimpered as their soaked waists squished together with the dense, gurgling churns of their cum turning their lower bodies into a pony spooge swamp. Blitz felt bits of his cum roll down his length and onto his testicles, while Dash's nectar had ruined their thighs, crotches, and the sheet underneath them.

Slowly, they lifted up their muzzles to look at each other, breathing and huffing into each other's mouths. Magenta eyes stared back into their own reflection, their noses flaring in unison, tasting and smelling their own mutual coupling.

Dash stroked Blitz's mane with a forehoof, squeezing the back of his head as she cracked a tiny, knowing smile.

Blitz chuckled nervously back, a shy grin and a large blush going across his blue snout quickly.

He opened his muzzle to say something, only to feel Dash seal her lips on his, giving him a proper kiss.

Blitz kept his wing and member inside of her, stroking through her own wild mane as his snout tilted to the side, letting the two siblings suckle onto each other's tongues. They swapped saliva as the crackle of their snouts breaking apart and resealing filled their ears, their eyes closed to enjoy the intimacy.

They stroked each others bodies, moving their forehooves through their sibling's fur. Their crotches peacefully and teasingly rubbed together, their tails swaying rapidly behind themselves, happy that their urges were purged, and perhaps a secret little game that the two siblings could enjoy from time to time had suddenly been invented.

All was well for the two Rainbows, and maybe, just maybe, they could have a secret little relationship and family fun together.

Except for Soarin', whose muzzle hung over Rainbow Dash's bedroom window, his eyes dots of shock as his wings were solid titanium behind him. If it wasn't for him gripping onto her ledge with his arms, he would have fallen off.

He was going to tell her about how he might have convinced Daring Do to meet her favorite fan with a little bit of wonder from his bolt. Instead, he got to see... this.

He might have to explain to Rainbow Dash why the side of her house smelled slightly of...

Him.

Author's Note

Remember, remember, the fifth of Neighvember, the Rainbow treason and plot.

And so I have officially written clop. It is likely I will do it in the future, and may do a sequel to this, but for now, my urge to write erotica has been sedated.

To everypony: I hope you have enjoyed yourself in many ways, as I have as well. It has been mentally and physically stimulating to say the least! If you get off mentally or physically, it's really... enjoyable to think I was able to do that.

Thank you to my old readers who happen to be perverts as well and don't hate me for doing this once. I'm not shocked you're all perverts. I am... too...

To those of you who have read just this, I would be honored if you gave my sex comedies a try. That is what I love more than anything, as skirting the M rating as hard as possible is oh so fun, as is writing our favorite fillies drunk, horny, and being Adult Swim approved mares.

Thank you, all of you.
