Truth or Dash

The hot air balloon drifted on the prevailing air current. Rainbow Dash and her five Ponyville friends rode along in the basket. Spike wasn't there. They would have invited him to come along but... they didn't want to. They were on their way to the Rainbow Festival in Hope Hollow where Rainbow Dash was to be the guest of honor and meet her fan club there.

It was getting late in the evening and everypony was very tired from the trip taking so long. Well, almost everypony. Pinkie Pie was still wide awake with her boundless energy. She was regaling them with the song of her people. And despite the basket being no more than two meters wide, she bellowed out the lyrics loud enough to make sure that every creature in the surrounding countryside below them could hear her as well.

"... Two bottles of pop on the wall! Two bottles of pop! Take one down, pass it around! One bottle of pop on the wall! One bottle of pop! Take it down, pass it around! No bottles of pop on the wall!" Pinkie Pie took a deep breath. "From the top! One hundred bottles of pop on the wall-"

"Hey Pinkie, does this smell like chloroform?" Rainbow Dash asked, covering her mouth with a rag. Pinkie Pie took a deep whiff to see if it smelled like chloroform. It did indeed smell like chloroform. Then Pinkie Pie decided that the floor looked exceptionally cozy and took a sudden nap. Rainbow Dash looked over at Twilight, expecting to get scolded.

"You know what," Twilight said, "I'm not even mad this time. Thank you, Rainbow."

"Thank goodness," Rarity said. "I need my beauty sleep!" Rarity nodded off almost as fast as Pinkie did and slumped against the basket wall, using Pinkie's supple pink rump as a pillow. Fluttershy, Applejack and Twilight were all still awake.

"What about you guys?" Rainbow asked.

"I'm too scared of heights to sleep," Fluttershy said.

"I'm too worried about my schoolwork I left behind," Twilight said.

"I can't sleep without my medicine," Applejack said. She opened her bag and took out a bottle of cider.

"You drink to sleep?" Twilight asked.

"At this point, I drink just to feel normal," Applejack said.

"Wow. And here I thought we needed an intervention for Dash," Twilight grumbled.

"Cider!? Sweet! Give it here!" Rainbow Dash said, grabbing a bottle from the bag and chugging it down.

"We still might," Fluttershy said.

"Okay, truth or dare!" Rainbow Dash said.

"How 'bout no?" Applejack said, wanting only silence after eight hours of Pinkie Pie singing.

"Truth!" Rainbow Dash answered for them. "What was the first dick you guys ever saw?"

"That's not how the game works!" Twilight said.

"Also, that's really inappropriate," Fluttershy said.

"Pfft," Applejack scoffed. "I work on a farm. What dick haven't I seen? All those animals, come breeding time, it's just dicks everywhere." She just sort of stared off into nothing as she was lost in her flash backs. "Just- like... a hurricane of dicks."

"I meant what was the first pony dick," Dash said, rolling her eyes. She looked over at Fluttershy. "I bet it was Zephyr's for you!"

"Rainbow!" Twilight scolded.

"What?" Dash said. "How could she not? The dude walks around with his boner out constantly whenever he's over Flutter's place!"

"Well, it's not like it's his fault," Fluttershy said. "He's just not always aware of himself. Besides, I blame myself and my stupid pheromones."

"Fluttershy, you shouldn't blame yourself," Twilight tried to council her.

"You can't tell me you've never been tempted to... you know..." Rainbow made an implying motion, thrusting her hips. Fluttershy balked.

"Rainbow, would you want to have sex with Zephyr?" Fluttershy asked.

"Eww! No! He's gross and he smells like he never takes a shower!" Dash said.

"So what makes you think I would want to have sex with him!? My own brother!"

"Because that would be so hot!" Dash said.

"You don't want to have sex with him because you think he's gross, but the idea of me having sex with him turns you on?"

"Hell yeah!" Dash said, grabbing another bottle of cider. "I bet he's the kind of ass that'd forget to pull out too and totally cum inside you and get you super incest pregnant!"

"Oh my gosh," Twilight grabbed a bottle of cider and drank it as fast as she could, hoping to black out as soon as possible. Rainbow looked over at Applejack.

"Come on AJ! There's a reason they call him BIG Macintosh!" Dash said.

"I'm aware," Applejack deadpanned.

"Ain't that how they do it down on the ol' farm?" Dash said, mocking her accent.

"I don't appreciate the stereotype," Applejack said.

"Twi, what about-"

"Fuck off."

"Come on! Having a brother must be like having a live-in coltfriend!"

"You really think that's what it's like?" Twilight asked. "Brothers are a pain. Always competing over everything..."

"Brothers are gross," Applejack said. "Always blowing up the outhouse..."

"Brothers are weird, always sniffing your bed sheets," Fluttershy said.

"What!?" Applejack balked.

"Ha! I knew it! Zephyr wants to sleep with you!" Dash said.

"Oh, no, he never wanted to sleep with me. He just sometimes watched me sleep from my doorway."

"Your brother watched you sleep at night?" Applejack asked. "That's creepy! What kind of sibling does that?"

"I know, right?" Twilight chuckled nervously.

"You never answered," Rainbow said. "Was Mac's the first dick that you saw? The first pony dick?"

"Of course it was!" Applejack huffed. "He's the only stallion on the farm. But that doesn't mean I wanted to go rolling in the hay with him!"

"Yeah yeah. What about you Twi? Was it Shining's?"

"Actually, no, it was my Dad's," Twilight admitted. "I kinda, sorta accidentally walked in on my parents..."

"Ha! Me too! Up top!" Rainbow Dash's offer for a hoof-bump went without return as Twilight glared at her. "My Dad's was the first one I saw too. And oh my gosh it was like..." Dash held her hooves up in front of herself a good distance apart indicating her father's size.

"Oh my," Fluttershy blushed.

"You're exaggerating," Applejack said.

"Not even a little bit, that's the thing!" Dash said.

"Well I'm sure it seemed bigger back then," Twilight said, blushing herself.

"Anyway, I told my dad that I wanted to do what my mom was doing with him, since it looked like it was so much fun. And they gave me the whole 'sex talk' and my dad told me that he wouldn't do it with me. And I realized that it must be because I'm a lesbian!"

"What the fu... That's not even how that works!" Twilight said. "That's not how any of this works! Dash, are you... are you actually retarded?" Rainbow wasn't listening to anything but the sound of her own voice.

"So I figured that if my dad wouldn't do it with me, my brother would! But I didn't have one yet. So I told them I wanted one, and my dad said they were trying their best. But they said that when I was born, I came out so fast I dragged half of my mom's organs out with me. But I still hold the record for fastest delivery at Cloudsdale General! Ten minutes flat!"

Fluttershy threw up in her mouth a little bit.

"Wow. That... is horrifying." Applejack said.

"But anyway, it meant that I could never have a brother. Unlike you lucky fillies! Talk about unfair!" Dash sulked. Applejack held up her bottle of cider.

"Twi, do you think you could turn this into a memory-erasing potion?" Applejack asked. Twilight's horn was glowing brightly as she focused on her own bottle.

"You think I haven't been trying!?"

"You guys all suck!" Dash said. "I'm an only child and you all have brothers! You guys owe it to me to fuck your brothers! If I had a brother, I'd totally fuck him!"

"Then let's just be glad that you don't have a brother!" Applejack said.

Hit the Showers

Twilight Sparkle woke up with a splitting headache. The same one that Applejack, Fluttershy and Rainbow Dash had. The note on her nightstand told her that she had given herself and her friends a memory erasure potion. She had been in this position before. Her curiosity wanted to know what it was that she had made herself forget. But she knew better than to actually find out what it was. There was a reason they had taken the potion in the first place.

"Ugh, what happened last night?" Applejack asked, looking around the room. They were in the 'Royal Suite' of the Hope Hollow Hotel. Though the label was surely overselling the dull-grey, run-down room. Twilight looked at the instructions that she had left for herself.

"We... had a drinking contest on the way here and... Rainbow Dash won," Twilight said.

"Ha!" Dash gloated, and then winced, clutching her head. Twilight passed around a vial of headache potion, being sure to leave most of it for Pinkie who had a different, but equally severe headache. Chloroform is a hell of a nap.

Rarity also slept poorly, but that was more due to the lumpy bed.

The group walked outside into the town. The mayor met them and told them that the town used to be the called 'the end of the rainbow', despite it looking very gray now after a magical mishap.

"If magic caused this, maybe magic can solve it." Twilight said. She tried to cast a counter-spell. It didn't work. "I guess I need to do more research."

"Let me try," Rainbow Dash said. She tried to solve everything by flying really fast. When rainbows and/or dashing didn't work, she was out of ideas. "Yeah, that's all I've got."

Just then, two pegasi foals flew past, trying to do some kind or aerial maneuver, zigzagging back and forth when they collided and fell. Rainbow flew over to help them, but they were able to recover just in time to not crash.

"Are you okay?" Rainbow asked.

"Why did you zig in front of me like that?"

"I didn't zig, you zigged! I zagged!"

"That's no excuse for-"

"Guys, guys!" Rainbow Dash broke up the argument. "Hold on! It was just an accident."

"An accident that happened in front of you."

"Ugh, I'm so embarrassed. All of our lives we've been wanting to meet you and-"

"Wait, so you're the fan club?" Rainbow asked.

"You've heard of us?"

"Barley is the president!" the colt said, pointing at the filly.

"Pickle is the Assistant President," Barley said, pointing back at the colt. "You're my brother's favorite Wonderbolt!"

"And my sister's favorite Wonderbolt, too!" Pickle said.

"He knows all your best moves!"

"So does she!"

"We practice all of them everyday!"

"But we really can't do them."

"Do you think maybe you could give us a lesson? Just a tiny one? Show us some of your moves?"

"Wait," Rainbow Dash said. "Wait... wait! She's your sister? And he's your brother? You're siblings!?" Her wings sprang open.

"Yeah," Barley said. "Isn't it obvious?"

Rainbow Dash squinted at them. Even under their fashionable hooded sweatshirt tops, and with their colors dulled, she could see that their coats and manes were the exact same patterns of shades of grey to each other. They were-

"Twins," Pickle said, as if Rainbow Dash's wingboner could get any stiffer. Her pussy winked beneath her tail.

"I'm older," Barley said.

"Only by a few minutes," Pickle argued.

"So what do you think?" Barley asked. "What moves should we work on first?"

Rainbow chewed on her lip as she tried to get her wings to relax.

"I think we should hit the showers!" she said.

"What? But we've barely done any flying yet!" Pickle said.

"True, but we need to work on your coordination first, and do some team-building exercises!" Rainbow said.

"... In the showers?" Barley asked.

"Hey, who's the Wonderbolt here?" Dash said.

"Fine! But I get to go first," Barley said.

"What part of 'team exercise' don't you get?" Dash said. "You bathe together, just like the Wonderbolts!"

"Um, there's really not enough room in the small tub."

"Tub?" Dash asked.

"Yeah. We just have a tub at home. The only 'showers' are at the school gym."

"Okay, well I did say to hit the showers, so let's go there!" Dash said.

"On a Saturday?"

"Yeah! Let's go!" Dash said.

The school was empty during the weekend, but not locked in the small town. They walked through the gym to the locker rooms on the far side. There was two, one for colts, and the other for fillies. Dash and Barley headed towards the fillies' room. Pickle automatically headed for the colts'.

"This way, Pickle," Dash said, waving him to follow them.

"Into the fillies' room?" he asked. "Isn't that against the rules?"

"Nope. Oh, sure, the Wonderbolts have lots of rules. But never forget rule number one."

"What's that?"

"I rule!" Dash said. "The Wonderbolts shower room is co-ed, so come on." Pickle followed after them into the fillies' shower room. To his surprise, it looked exactly the same as the colts' room. He always though that it would be gold-plated walls or something. "Alright, shower time!" Dash said, turning on the water. She stepped under the warm spray and waited while Barley took off her shirt. She stepped under the shower head next to the one Rainbow was using. Pickle watched the water running off of the two mares, and hesitated by the benches, keeping his hoodie on.

"You too, Pickle. Come on," Dash said. Pickle nervously peeled off his hoodie and walked over to another shower. "Nope! Over here with Barley. You shower as a team!" He slowly walked over to his sister, hoping she didn't notice what his hoodie had been hiding. She didn't notice his predicament. But Rainbow did. "Ah, no wonder you've been having trouble flying," she said, pointing at his erection. Barley followed her gaze and saw her brother cross his legs to try to hide his shame.

"Sorry sorry!" he cried, feeling mortified.

"It's okay," Dash said with a smug grin, "I'm aware of the effect I have on ponies. Especially since you're at just the right height to... enjoy the view." Dash turned her rump to him and flagged her tail, presenting her pussy to him less than a foot from his snout. "But if you're going to be able to fly well, you're going to need a bit of stress relief first." She made a 'jerking off' motion with her hoof.

"But Barley-"

"Barley should too!" Dash said. "All of us, actually, since we're a team now." Dash grabbed the shower head off the wall holster and held it with her wing, directing the spray under her tail. "Aw yeah! That feels good! Really gets all that stress out. Especially at your age, guys. All that sexual tension used to drive me nuts as an only child. Luckily you have each other." Dash set her shower head back on the wall and grabbed Barley's, pointing the stream of water under the filly's tail, making her shudder and moan.

"Here." She gave the shower head to Pickle to hold, keeping it aimed under his sister's tail. Pickle held it as Barley hooves shuffled in place and her knees started to go weak.

"Pickle..." she moaned.

"You're making her feel so good! But you know what feels even better? Using your tongue." Dash pushed the shower head aside and leaned down to lick Barley's filly bits. She gave her long licks up and down her little pussy, sticking it into her entrance and flicking her clitoris with her tongue.

"Oh my gosh oh my gosh!" Barley cried out. Dash could tell she was getting closer. But it would do them no good if she got her off too soon. So she stopped, leaving her in the lurch.

"Did you see what I did for her?" Dash said. Pickle just sort of nodded, mesmerized by what he was seeing. "Alright. Let's see what you can do. Why don't you practice on me first?" She turned and presented herself to Pickle again, lifting her tail for him to get a good look at her marehood. "Go on, check it out!"

Pickle couldn't believe his luck or his eyes. He shuffled closer and reached out with his hoof, just barely touching her blue outer lips. He moved it aside slightly, revealing her wet, pink interior. Her clit winked at him.

"Whoa."

"Hehe, yeah it does that sometimes," Dash said. "That just means that a mare is in the mood for sex. Why don't you give it a lick like I showed you?"

Pickle stuck out his tongue and gave her a quick, experimental lick. Despite it being in the general butt-hole region of a pony, it didn't taste as bad as he expected. In fact, it tasted good. Really good! He dove back in for more, pushing his whole muzzle into her pussy, licking as deeply into her vagina as he could.

"There, that's the spirit!" Dash said. "But try focusing on the little nub sticking out." He pulled back and gave her clit a lick and a little suck. "Oh f-fuck yeah! That's it! That's the way to do it!" Dash looked over at Barley who had grabbed the other shower head and started spraying her own pussy with it again. She stepped away from Pickle to stop Barley from getting herself off. That was supposed to be her brother's job.

"Okay," Dash panted, "Good practice. But we're missing the most important part." She grabbed the other shower head away from Barley. "Teamwork! So show me what you can do by doing that to Barley."

"But- but he's my brother!" Barley protested.

"Exactly! You guys live together. And as a team you need to take care of each other. Especially when it come to stress relief like this! And you're lucky, Barley, he's really good. A natural team player! Go on Pickle, show her!"

Pickle didn't voice any objection. If she tasted anything like Dash, he knew he would enjoy it. With Dash's encouragement, he dove right into his sister's pussy. As soon as he tasted her, he enjoyed it right away. She didn't exactly taste like Dash. She was a bit more tart, but also a little less bitter or watery. It was almost like a syrup on his tongue. A syrup of his sister's sweet nectar. He wanted to just lap her up, as deeply as he could, but he remembered Dash's instructions. He looked for her little nub. His sister's was much smaller, but it was proportionate to her fillyhood. He did the same thing, licking it and giving it little sucks.

Barley's front legs gave out and she slid forward onto the tile floor. Her hind legs locked out as she propped her butt up in the air at him. Her damp tail flagged higher and draped backwards along her back, giving him total access to her.

"Oh my gosh! Pickle! PICKLE!" Barley cried out. Her whole body shook and her pussy quivered and winked harder. Pickle felt hot spurts against his lips and chin, dripping down his neck. Dash grabbed his mane and gently pulled him off of her.

"Easy there tiger," she said. "You just made your sister cum! Give her a minute to recover." Pickle just stared at his sister's dripping pussy. His dick slapped against his belly. "Here," Dash directed him. "Why don't you come take a seat over here on the bench." He climbed up, completely on the bench, resting down on all fours, covering himself as he did. "No no, like this. Sit upright!" Dash adjusted him so he was sitting on his butt with his hind legs hanging down and his dick sticking up in front of him like a steel bar. "Perfect!" Dash walked over and helped Barley walk after she recovered from her orgasm. She sat her down in front of her brother, and Dash knelt down beside her.

"Alright. I showed him what to do for you, now I'm going to to show you one of the things to do for him," Dash said to Barley.

Dash leaned over and opened her mouth, taking the tip of Pickle's pickle in her mouth. She bobbed her head a few times, swirling her tongue around on his tip in her mouth, flicking along his sensitive flare ridge. But she didn't stop there. She swallowed more and more of his length. It was actually quite easy for her, since he was still a colt and she had taken bigger dicks before. Barley was in awe, watching Rainbow swallow his entire length. Pickle gasped, feeling it happen until her nose was pressed into his belly and her chin was touching his balls. Dash slowly pulled back off until her mouth was empty again.

"Feels a lot better than your hoof or wings, huh?" Dash asked him. He didn't know what she was talking about. He just gave her a goofy grin. "Okay Barley, you give it a go. Don't try to take the whole thing like I did. That's a pro-level move!" Barley leaned forward and opened her mouth to at least get the tip of her bother's dick in her mouth. She took a few inches and started to gag. "It's okay. It takes practice. Use your hooves or wings to help while you bob your head. She did as Dash instructed. Pickles hips jerked and made little involuntary thrusts. She could taste his salty precum in her mouth. It didn't taste all that great, but it also wasn't as bad as she feared. He started making little moans.

"Okay, don't get too carried away," Dash said, "or else he'll finish in your mouth!" She looked at Pickle. "You should never finish in a mare's mouth unless she wants you to. Especially your sister!"

"But- but what do I do now!?" he asked, desperate for release.

"Relax! The best is yet to come!" she said. "Come on and get up," she said. He got off the bench. Dash brought him around behind Barley and lifted her tail. "Alright bud! Climb on up! It's time for the big finish!"

"Wait! We're really going to go all the way?" Barley asked. "Like... actual sex?"

"Yup!"

"Can't I with you instead?" Pickle asked Dash. Dash tried not to laugh at him.

"Sorry kiddo but you're-" She stopped herself from saying 'too small for me to even feel it'. She re-worded it. "I'm too tall for you to reach. And besides, since you're twins, you'll be a perfect fit for each other!"

"But he's my brother. I thought that siblings don't-"

"Hey! Brothers and sisters have sex all the time!" Dash said, genuinely believing it despite being told to the contrary by her liar friends.

"Really?" Pickle asked. "I've never heard about that."

"Well duh! No pony admits to it because it's a secret!" Dash said like it was the most obvious thing in the world. "I mean, you don't hear ponies going around blabbing about who they have sex with. That would be impolite. Do you really want to hear that stuff from your parents?"

"Ew! No!" Barley said.

"Exactly! So don't tell them about this either!" Dash said, helping Pickle mount his sister, lining up his dick with her wing.

"Why not? I thought you said all siblings do it," Pickle said.

"Because sex is fun!" Dash said. "Especially with your sibling! And you know how much parents hate it when you guys have fun, right?"

"Oh, they so do!" Barley said.

"Exactly! So you need to just keep this secret fun between the two of you! If you thought his tongue was good, you're gonna love this even more!"

"Wait! don't we need a condom? I remember that being an important thing," Pickle said.

"Pfft, yeah if you're having sex with a dirty street whorse!" Dash said. "A condom is to keep you from getting sexually transmitted diseases. But your sister isn't a dirty street whorse, is she!?"

"No! Of course not!" Pickle said.

"So she doesn't have any sexually transmitted diseases!" Dash said. "And as long as you only have sex with each other, than you'll never have to worry about that and you never use a condom!"

"Makes sense to me," Barley said.

"Me too, Pickle said. Dash put her hoof on Pickle's rump and pushed him forward, guiding him with her other hoof. She rubbed the tip of his penis against his sister's pussy, getting it slick with her juices. Another push and a bit more pressure and the broad tip finally popped in. Barley gasped when she felt her her brother's dick slip inside her for the first time. "Okay, so now what you do is-"

"I know how to have sex!" Pickle said defensively. "I'm not a little foal!"

"Oh, okay then, go for it. I'll just watch from over here," Dash said, sitting on the end of the bench.

Pickle pushed his hips forward, sinking the rest of his rigid shaft into his sister's tight vagina. She felt snug around him, and he filled her just enough without stretching her uncomfortably. Barley felt the tip of his dick just barely kissing her cervix as his balls rested against her loins. Just as Dash said, the twin siblings were a perfect fit together like lock and key. Pickle held himself there, hilted inside her, clearly enjoying the feeling of her wrapped around him. A look of concentration was on his face.

"It's so warm," Barley said, feeling him inside her. "It's- I can feel it coming!"

"Wow, already!?" Dash asked in surprise. Pickle nodded. Even with all the teasing, Dash hadn't expected him to cum instantly.

"There's so much!" Barley gasped, feeling herself being filled. It started to spurt out and run down her legs. "It's leaking out!" Dash leaned over to look in excitement. Her eyes followed the trickles running down the filly's legs to the yellow puddle forming at her hooves.

"Wait- did you just-" Dash couldn't stop herself. "Ba-ha-HAHAHA!" She laughed out loud. "What are you even doing!?"

"Having sex," Pickle said matter-of-factly. "Duh!"

"That's not-" Dash couldn't even get the words out between fits of laughter. "That's not- how you have- sex!" Dash clutched her sides. Her ribs hurt from laughing so hard. Pickle didn't understand what was so damn funny. "You don't pee inside her! You're supposed to cum!"

"I did. I came here and we had sex," Pickle said. Dash just laughed harder.

"No no, you-" Dash wheezed, wiping the tears from her eyes. "You're supposed to cum. You know, ejaculate?" He gave her a blank stare. "You know, when you clop off and white goo comes out?" His expression remained unchanged. "You mean you've never- cum?" she asked. He shrugged.

"I guess not," he said.

"Oh my gosh oh my gosh!" Dash squealed. "This is gonna be the best! Okay, so it's like, when you were licking her, and she squirted, it felt really good for her. Didn't it?"

"Oh yeah! The best feeling in the world!" Barley said.

"Yeah! That's what cumming feels like! So now you get to do it!"

"Okay then... how?" he asked.

"Well, first you push your dick in," Dash explained. He looked at her, and then at himself. It was already in all the way. "And then you pull it back out." He pulled out. But he pulled out all the way. A big gush of his pee came pouring out of her. "Okay, you're not supposed to pull out all the way. You're supposed to stay inside the whole time. Just pull out like, three quarters of the way." She guided him with her hoof again and he pushed his dick back inside his twin sister. Once it was all the way in, he pulled it back out most of the way, but managed to stay inside this time. "Now push it back in."

"I don't get what the purpose of this is," he said.

"It's like doing wing push-ups! You gotta do a lot of reps in a set!" Dash explained in exercise terms. "Just keep doing that motion." He did as she said, moving his hips and thrusting in and out of Barley. Each time he pushed in, his balls would hit her clit, sending little spikes of pleasure through the filly. She chewed on her lip as she felt another orgasm building inside her, like a rope in her tummy tying itself into a bigger and bigger knot, pulling tighter with each thrust, threatening to snap free soon. But she also felt another hunger, looking at Dash, watching them from the bench, rubbing herself with her hoof.

"Dash, I- I kinda wanna lick you like Pickle did," she said.

"Oh? Well sure, come on over!" Dash said, laying back on the bench.

"But Pickle is-" she moaned, with the weight of him on her.

"Come on guys, both of you walk together. Teamwork, remember?" Dash coached. Barley shuffled carefully, taking small steps over to Dash while Pickle held onto her waist and followed in step, keeping himself inside her. At the bench, Barley was able to lean on it while her brother continue to fuck her. She pushed her face into Dash's pussy and started to lick just lick how she knew she would like it to be done to herself.

"Oh, that is good!" Dash said. Barley brought her hoof up under her chin to play with Dash's pussy while she licked and sucked on her clit. Her hoof prodded and teased at her entrance, pushing just a little more and more. She wanted to see what Dash's limit would be. She started to push the tip of her hoof inside her, and then the rest of her hoof.

Dash was in heaven, watching the twin brother and sister fucking right in front of her while the filly ate her out. She felt her push her hoof inside her and it was even better. The filly's hoof was approximately the same thickness as an average stallion's cock anyway.

"Oh my gosh!" Dash moaned. Barley stopped, thinking that she was going to tell her to pull it out. She started to pull back. Dash bent her hind leg to bring the heel of her hoof to the back of Barley's elbow. "No. More. More!" She pushed more of her hoof in. Barley got the hint and pushed in more herself in little thrusts to simulate what Pickle was doing to her. She wondered how deep she could go, pushing in more and more of her foreleg until she was almost elbow deep. She felt her hoof bump into Dash's cervix and tried to fuck deeper into her with her punching hoof. Dash winced and grunted as she lurched forward a bit.

"Oof, okay! That's deep enough!" Dash said. Barley back off a bit and just kept thrusting with her hoof inside Dash while she leaned down and kept licking and sucking on her clit. Pickles thrusts became more erratic.

"It- it feels funny!" Pickle stuttered. "Like I'm gonna pee again but- but I-"

"Keep going!" Dash coached. "Whatever you do, don't stop!"

Barley felt her brother's penis flare inside her, stretching her even more as it moved back and forth across her g-spot even harder.

"I- I'm-" Barley couldn't even get the words out as she flopped forward onto the bench, pressing her face into Dash's pussy harder as her brother continued to plow her as hard as he could. "Cumming!" she cried out.

"You'r cumming!?" Dash asked excitedly.

"Ye-e-e-sss!" Barley cried out as her pussy twitched and winked around his thrusting dick, squeezing him harder with each of her pussy's contractions. Her fresh wetness dribbled down her legs and his shaft, onto his balls, now makeing wet slapping noises with each hilt.

"Your brother is making you cum!?" Dash asked.

"Yes!"

Say it!"

"My brother is making me CUM!"

"OH FUCK!" Dash squealed as her own hips bucked against her foreleg inside her. Dash came hard. The first jet of her marecum sprayed Barley in the nose. She moved her head out of the way of the second spurt, just as hard and voluminous as the first. It arced over her back and into Pickle's face, dripping down his snout and into his open, panting mouth.

Barley pulled her hoof out of Dash and slid off the bench. Her knees locked up and her front hooves gave out as she bent over and pressed her cheek to the floor, face down ass up. It was the last straw for the poor colt.

"I'm- I'm gonna- UH OH!" He started to stagger and tried to pull out of her from the over stimulation.

"No!" Dash screamed. She leaped off the bench and ran over to behind him in a flash, pushing on his butt with her hooves, pushing him back inside his sister all the way. "Keep it inside! Keep it as deep inside as you can!"

"Oh- oh OHHH!" he groaned as he was about to ejaculate for the first time in his pubescent life. His hooves wrapped around his sister tightly. His dick head was pressed hard against her deepest barrier as it flared even wider, stretching her cervix entrance just the slightest bit. As his balls tightened and his dick pulsed and throbbed, he was perfectly lined up with his twin counterpart. "Augh!" he cried out as he came deep inside his sister.

His dick pumped in time with his heartbeat, filling the almost-nonexistent space in the back of her vagina instantly. His wide flare sealed her tight pussy, preventing any from leaking out. Each thick rope of potent seed spurted straight through the small opening directly into her fertile womb.

"AH! I- I'm!" Pickle's mind went blank as the most incredible feeling of his life filled his every sense. His entire world was his penis, and his sister that he was inside. That he was cumming inside.

"You're cumming!" Dash said, seeing the base of his shaft throbbing again and again, delivering its massive load deep inside his sister's pussy, stretched taut around his dick. "You're cumming inside your sister!"

"YES!" he yelled.

"Come on! Say it!" Dash begged as her hoof moved like a blur on her own pussy. She just needed to hear that line to get herself off one more time. He didn't think about it. He didn't have the capacity to think. He only did as he was told.

"I- I'm cumming inside my sister!" he cried out.

"OH FUCK YES!" Dash squealed, nearly collapsing herself as she came again against her hoof. "That is the hottest thing I've ever seen!" Barley's knees finally gave out and her back half flopped onto the floor with the rest of her. Pickle moved with her, still balls-deep as they laid panting on the floor.

"Doesn't that feel awesome!? Don't you guys love it!"

"Yes," they both moaned.

"Don't you guys love each other?"

"Yes," they said.

"Well go on! Say so!"

"I love you, Barley."

"I love you too, Pickle," she wheezed, feeling his weight on him. Pickle realized he was squishing her and tried to lift himself off.

"No no!" Dash said, moving over to keep him in place.

"But I'm squishing her," he said.

"Alright guys, roll on your sides. But stay inside her!" Dash said. Holding onto her they slowly rolled onto their sides, taking care to to keep him as deep inside her as they could. Dash moved over next to them and gave his hips a push, getting him the rest of the way back in.

"Ooh," Barley moaned, rubbing her belly.

"Sore?" Dash asked. Barley nodded. "Yeah, well it's just like any other exercise. You gotta keep at it. Every day, you two. Got it?" They both nodded. "A lot more fun than regular exercise though, isn't it?"

"Yeah," they both said.

"Oh no, coach Dash!?" Pickle whimpered, looking down at himself. They all watched at his erection slowly wilted and began to slip out of his sister. "I'm sorry! I'm not doing it on purpose!" he said.

"It's okay," Dash said. "That part happens eventually." His dick finally slipped out of her, followed by a dribble of his cum starting to leak out. Dash leaned down and gave it a lick. "Mmm, good stuff kiddo. She'll get a lot of energy from that."

"Really?"

"Oh yeah," Dash explained. "When it's in a stallion's balls it slows them down and makes them cranky and clumsy. But when you put it into a mare, it gives them energy and focus!" With the ache in their respective loins gone, and the clarity in their heads after cumming, it was hard to argue with Dash's logic.

"That's why you need to do this as often as possible," Dash said. "And only with each other! And you need to make sure that you always cum inside your sister, because that's where a brother's cum belongs. Okay, Pickle?"

"Yes ma'am!"

Barley moved her hoof down to her pussy to try to keep her brother's precious cum from leaking out of where it belonged. Dash rummaged through a few of the lockers to find something suitable. She came back with a small, rubber racket-ball. She rubbed it against her pussy and then moved Barley's hoof out of the way and pushed it inside her, plugging the leak.

"There! Now his cum is safe and sound!" Dash said.

"But- how are we supposed to have sex again if that's inside her?" Pickle asked.

"Well, cum is kinda like milk. It goes bad after a day or so," Dash explained. "So Barley, when you go to have sex again, just squeeze the ball out and let the old stuff drip out first. As long as you guys make sure to refill again!"

"Of course!" Pickle said. They helped Barley to her hooves. "How does it feel?" he asked. Barley shifted her hooves and looked at herself. She didn't look nearly as bloated as she felt like she would be, and she could only just barely feel the rubber ball hidden inside her vagina.

"I feel fine," she answered. "Mostly I can feel you inside me," she said to Pickle, swaying back and forth a little. "I can feel your cum inside me, sloshing around like a big meal."

"But don't you both feel better now?" Dash asked.

"Yeah!" they cheered.

"Alright. Good team-building exercise!" Dash said. She turned the showers back on. "Now let's hit the showers for real and get washed up before we go flying. Remember, you have to make sure you don't get caught doing something this fun or else you'll get in trouble! So no telling anypony! Not your family or your friends! This is a super secret just between you two!"

"We know," they said in unison.

"Alright then. Hit the showers!"

Later that day the rest of the town celebrated the Rainbow Festival. Princess Twilight Sparkle and the rest of her friends were able to dispel the Hopeless Magic, bringing back color to the town and saving the day with the Magic of Friendship (again). As the festival got underway, Rainbow Dash and the Barrel twins did a fly-by.

"Attention everypony!" Dash called out. "Introducing Hope Hollow's very own Junior Wonderbolts!"

"Did you hear what she called us?" Barley asked her brother.

"Did you hear what she called us?" Pickle asked back.

"Junior Wonderbolts!" they both cheered as the color returned to their fur, manes, tails and tops. They flew with Dash up to the cloud tops and got into position.

"Okay guys," Dash said. "Show time!"

Rainbow Dash flew really fast and created a Sonic Rainboom. The Barrel twins followed after her lead through the concentric rings of color, performing the routine they had been practicing after they showered. They executed the maneuvers perfectly and came to a three-point landing just as they planned. Dash landed on the stage next to Twilight.

"Wow! How did you get them to fly so much better in just one day?" Twilight asked.

"Wonderbolts secret training," Dash said with a smug grin. She looked down at the twins and winked, knowing what they would be doing with each other from now on. Dash would be clopping to the thought of it just as often. The twins hugged each other and their flanks flashed with a magic light, as they each got their matching cutie marks at the same time: A pickle stuffed into a barrel of barley oats. That was their special talent that they shared. Dash smiled and turned to Twilight on the stage behind her.

"Now this is something I'm proud to be a guest of honor for!" Dash said.
