Relatives, Rainbows, and Relationships

Rainbow Dash needed a penis inside of her.

It wasn't that she was straight: She loved vagina quite a bit, and the mare rump just had... something that a stallion plot couldn't quite fully deliver. Not that she didn't mind checking out colt balls either. But she needed something warm, alive, pulsating, and emptying inside of her. And if her memory recalled, stallionhood happened to be pretty good at doing that.

Doing. Olympus did she want to be done in. She wanted some colt who wasn't a prick or using her just for her body to fill her. A decent guy who was really funny and pretty good looking. He didn't need to be an athlete. As long as he could accept for the fact that he would never, ever watch or read pornography without her approval.

Pornography. She couldn't nap anymore with that thought in her head, and yet she knew it nor her sex toys weren't going to be enough to sedate her loins.

Damn it, she was getting wet and waking up from a good nap.

Rainbow Dash opened her eyes slowly to scan over the horizon. The splattering of the rainbow waterfalls around her villa filled her ears, as did the stream that rolled off of her lawn and melted into the heavens filled her eyes. She had taken a nap against her brother's frame after talking, laughing, and joking for hours about how much the last few years had changed their lives.

She had become a Wonderbolt trainee, a local hero, calmed her more bitchy side, and saved Equestria more times than she could remember. Blitz had kicked off his metal band Rolling Thunder, done pretty well, toured most of Equestria, and had plenty of stories and sight seeing recommendations that she added to her to-do list.

Doing. Son of a bitch.

Dash rolled herself over onto her back with a faint groan. She sat up, staring down at her marehood and the liquids she could feel bubbling inside of her. As if she needed to check herself, her left forehoof pulled gently on a labia lip, pulling back the blue fold to expose her pink insides.

Yep. She was getting wet. She wasn't shocked.

"Damn it," she whispered to herself, tracing the edge of her forehoof up the side of her fold, "I need to clop before I freakin' get wetter near Blitz. Because that's what I want him to see."

Or... did she?

The simple thought of wanting Blitz to see her aroused was purged by her idly massaging her left lip with her forehoof, pressing and releasing on the flesh. She let the gentle rolling motion of her hoof kneading into her sex fill her mind, and for a moment, it worked.

Dash let out the faintest of sighs at the spreading and releasing of her labia, pressing the very tip of her dark blue hoof inside of her marehood, letting it nip at the liquid building inside of her. Her eyes closed to embrace that calm, rubbing her hoof in a slow semi-circle between her vagina, stimulating the release of her nectar. Her tail flicked contently behind herself as she reached down with her right forehoof to join in the casual masturbation, using both of her hooves to press together and pull open her navy lips, letting her pink insides expose themselves to the world.

For some reason, this current session of masturbation was working a lot better than her last ones, and by the time she removed her forehooves from her groin, she could see a steady trickle of cum from her sex leak onto the cloud that helped form her lawn.

Buck did that little getaway work. And to top it all off, she brought her left forehoof to her muzzle like she nearly always did, licking at the hardened tip to taste her own slightly sweet secretions. She had asked - although not shown, but very tempted too - Twilight why her mare nectar might taste slightly of sugar, and Twilight's response was that a small percentage of ponies had a bit of 'unique' flavor to their cum.

Dash was cool with her honey being a pinch of liquid candy for somepony to drink.

She pulled herself up onto her four hooves, shaking herself off with a soft nicker as if she had dunked herself in cold water.

Damn she felt better, but she still needed to release herself, and her craving for penis still existed. Hay, it had grown even larger after she teased herself. But that option wasn't available to her. She'd have to deal with a dildo in her room for today, and her wings spread to take her from her lawn to her room.

Until she stopped.

She had trotted forward a few steps, and for some reason she couldn't rationally explain, her muzzle turned around to look at Blitz. Without her frame supporting him, he had fallen onto his side, and continued on with their two hour nap.

And exposed his sheath.

It wasn't like she hadn't seen it a thousand times before. Ponies were naked, he was her brother, and they had tackled each other as kids and, well, existed. A pony didn't think anything of nudity. Neither sex got publicly aroused easily at all, despite extensive flirting; it was 'genetic that ponies have evolved to nearly always only get aroused when they consciously want to' Twilight had said.

But Blitz's dark blue testicles and unaroused sheath looked... so... tasty.

Dash slowly licked her lips. A quiet, feral huff puffed out of her nose as she stared at his scrotum. A scrotum belonging to a cute, spiky haired, lean, funny guy. Exactly the kind of guy she was looking for.

To nearly all of ponykind the simple thought of having sexual flirtations with their siblings would have been considered a good suggestion to go to a psychologist. But Rainbow's hormone filled mind had a workaround.

She rationalized he was a childhood friend who she had decided to surprise for having had such a long trip and coming out of his way to visit her. Blitz had admitted that he wanted a girlfriend to her anyways. And like her, perhaps chasing a few tails was starting to get a bit old.

Dash was here to deliver on all fronts. A brother? She didn't have one! This wasn't her friend, this was her coltfriend who just happened to have been holding in his prostate for far too long.

She trotted forward quickly, laying down beside him to nose her snout right against his testicles. It was impossible for her nose not to flare at the scent of stallion blasting to the very rear of her mind, and any genetic barrier screaming for her to stop was muted by that wonderful scent.

Her thick tongue reached out to lap at his scrotum wetly, letting the faint flavor of stallion nip at her tongue and add rocket fuel to her sex drive. Her tongue caked his testicles in her spit as her muzzle moved forward, kissing gently along his orbs, her muzzle moving upward toward his penis tip.

Blitz was getting aroused, which was to be expected. He was mostly asleep, but stallions did get semi-hard from time to time asleep if her biology lessons - or past experiences giving surprise oral - were to be remembered.

There it was. The very tip of his flared, night ocean colored shaft pressed out of his sheath as he whickered quietly in his sleep.

It was Dash's now.

Her round snout pressed right into the head of his penis, and she lapped at it as if it was a large lollipop. Sticky strands of her saliva oozed down his sheath while her hot breath hovered over his groin. Dash's magenta eyes were barely open as she had been pulled into a sexual utopia.

Finally, after so long... stallion.

Dash's lips sealed around the tip of his member with a soft pop, kissing on the taste of Blitz's dick nipping on the edge of her tongue. He was getting harder, and Dash's muzzle more than willingly accepted his shaft. She quietly suckled on the top of it as if it was a frozen popsicle, bobbing her head to let his warm penis throb in her snout.

She was so wet. She could feel her cum stick to her inner thighs and it drove her nuts. The tips of her hindlegs tickled at her throbbing arousal.

As her spittle drolled down his semi-hard stallionhood, her lips popped off and resealed around the head, her wide and thick tongue circling over his shaft. Her forehooves had begun to scoff at his lower stomach, perhaps in an instinctive need to get his attention.

His shaft was the perfect size. Not too small, large, thick, or thin. She wasn't exactly capable - or wanting - to take massive stallionhoods, preferring technique over raw girth. Like her family and herself, he was on the leaner side, and it was glorious.

"Mmm... another excited fan huh? Sleipnir, mare, you must love me."

Dash's ears perked up to Blitz's voice.

It wasn't Blitz, it was some other lead singer to Rolling Thunder. Sure, they needed some work, but 'Ball of Lightning' was a catchy song.

"Hay yeah I am," Dash nickered seductively. Her brain was on autopilot. It needed his penis in her mouth. His cum in her stomach. "Really good for new guys. I think by album three, you'll be killer."

Blitz shuffled in place, moving a forehoof toward Dash's side to both pet her husky coat and stroke down her toned core. His eyes were barely open as he stroked Dash like a cat, which only gave her more incentive to pleasure his nearly completely hard shaft.

"You are both cute and hot," he said, scratching at the side of her stomach. "Unlike other lead singers, I please the rare mare who wants me for nothing. Come over here. You smell... different. Has to be that scented cum thing."

She looked back at him, pulling her drooling snout off his curved member. "Ya know, if you say a mare smells 'different' most of the time, you're gonna get your balls in your prostate. But yeah, I got that."

Dash took half of his cock inside of her muzzle to his obvious, sighing delight, pulling on Blitz's dick with her hot air to the reward of his pre dripping on her tongue. His penis left her mouth with a rumble of content escaping from her throat, her tail smacking loudly on the ground in delight.

"Oh buck yes. I've been craving colt cum for so long. And you'll eat me out? Totally go for it, hot shot."

Blitz didn't need to be told twice. Offered a free blowjob and a free pie to eat out of? He couldn't ask for much more than a good record deal.

Dash squeaked as she was dragged over and pulled on top of Blitz, now free with her forehooves and wings to do as she pleased. Her lips continued their succulent popping kisses of his flared tip, teasing every little nip of his pre from inside of him.

She loved that sweet taste, and needed it. She lived for it right now, and would do anything to get more of it. Her tongue suckled around his tip as she bobbed her muzzle up and down the top third of his member, her forehooves stroking his exposed length to feel every little vein twitch in her grasp.

Blitz couldn't contain himself. His eyes shot open to take in the sight in front of his eyes as Dash seemed keen on making him lose himself. He saw nothing but Dash's wind trained, martial art built, fitness curved rump directly on his neck, and he would be lying to so many parts of himself if he didn't say it was the nicest rump he had ever seen.

His forehooves stroked up and down her lithe flanks, massaging the tender muscles underneath her tight withers. He couldn't stop looking at her rump, nor could he keep himself from pressing his nose right into her marehood. Her blue lips had opened to expose her pink insides, and her cum oozed onto his muzzle and tongue. She was practically on fire on the inside, and the only thing keeping her vagina for boiling over was the ample amount of drizzle that caked her pussy.

Dash's eyes were focused solely on Blitz's shaft. She was getting that teasing treat of his pre that dripped onto her tongue and melted over her taste buds, feeding her carnal need to feel his cum blast down her throat.

But his pre wasn't enough. The feeling of her forehooves feeling every throb of his penis inside of her muzzle wasn't enough. Her drool pouring down his cock and the taste of stallion dick wasn't enough.

She needed his cum. Now. Damn her own orgasm. She needed to feed.

Dash removed her forehooves from around his base, her wings spreading loudly by her sides, only to wrap both of them completely around his length except for the tip. She gave his member a test squeeze with her famous wings, the curled, rounded tendons and feathers offering both a rigid, flexible, and extremely warm sheath for his penis to rest in. Soon, her muscles gently contracted and released around his shaft like a biological penis bump, squeezing in to let him feel her wings hug his shaft with her feathers sealing in the warmth. When she released, cool air and the tickling break away of her feathers tracing over Blitz's stallionhood shot pleasure up his spine.

All Dash had to do now was seal her lips around his head, and pull as hard as she could on his dick. She did exactly that, wanting her drink. Needing that life source. And she would get that colt cum.

Blitz came harder than he had in his entire life.

Blitz screamed at the top of his lungs as Dash abused every bit of her sexual experience, mating desire, and physical training to fry his brain completely. Dash could feel the rush of heat and blood from Blitz's penis as it turned as hard as steel, opening up to blast his sperm directly at the back of her throat.

Burning hot, thick gushes of stallion cum hammered the back of Dash's throat and dripped down her tongue and gums. The stout, thick, and then slightly bitter flavor of colt batter that plastered her mouth was that heroin high she had missed for so long, and she drank from Blitz's dick as if it was the fountain of youth. His cum rolled down her throat like she had never drank before, and she wanted to bask in it.

Bask. Yes. Bask in it!

She pulled her muzzle off of his penis, rewarded with pulsating shots of his cream shooting up nearly three feet into the air until it curved down to splatter on her face.

"Buck yes, coat me!" Dash cried, her eyes shutting as his cream splashed across her muzzle like the thickest of raindrops. Her once blue snout was painted with Blitz's jizz, ruining her famously colored bangs and scalp, coating it cloud white in sticky, dense colt slop. It dripped down her long ears and bangs, rolled down her cheeks and eyelids, and landed back on his own groin as Rainbow accepted her white baptism by fire.

All she could taste was cum. All she could smell was cum. All she could be was Blitz's cum that her wings squeezed out of him with every cry of euphoric Tartarus that Blitz was forced to endure.

But eventually, his member could give no more, and Dash knew all too well as the shots only landed on her nose tip, ending with his penis twitching with what it couldn't give.

Blitz barely sounded alive with the amount of choking, wheezing, and panting that echoed from behind Dash. He had given up trying to sample her sweet mareness, instead keen on screaming himself raw with the amount of pleasure that Dash had forced him to feel without his full consent. Instead, he had to simply accept that her sticky dew had completely soaked his neck, and that he wasn't quite sure if he was part of the realm of the living anymore.

Dash's vagina vodka had explosively discharged pretty much over his entire snout like a chemical weapon. Dash hadn't even felt her own orgasm. She was so consumed with her vampiric hunger for his liquids that she didn't even realize she had came herself.

Although... that would explain why she suddenly felt like her vaginal walls had just open up and dumped her juice on him like a cup of watered down honey tossed at someponies face. And she was usually a squirter.

Dash was as happy as a kitten with string regardless of how she didn't feel her own orgasm actively until the post-orgasmic high pranced in her brain like Pinkie did everywhere. She nipped playfully at his softening member and wore his spooge like war paint, licking her lips of one last taste of the goo that had been so evasive for so long.

And then it hit her like a train.

She had just drank a cup of her brother's cum and wore another cup of it.

And she had pretty much pseudo-raped him.

"Dash... if... if you think... I didn't know what you did..."

Dash swallowed down several strings of his sperm lodged in her vocal chords at the voice of Blitz in her ears.

She couldn't open her eyes, even if she wanted to. The shame had crushed her. What she had done, was unforgivable.

"Because... it was... amazing, mare. And when... when I'm not dying... I'm gonna get you back."

And then the shame melted away. Replaced by the most perverted part of her mind squealing up and down.

Apparently, that part of her mind ran in the family.
