Chapter One

“A free spa treatment?! Are you serious?!” Pinkie Pie clutched the ticket in her hooves and jumping excitedly around the room. The floors of Sugarcube Corner creaked and threatened to fall apart from the barrage of excitement coming from the pink mare. “Of course you’re serious! Wohooo!!!”

“I’m glad you like it, Pinkie Pie.” Rarity giggled, trying not to move lest she experienced an unfortunate collision with the excitable bundle of energy that was her friend. She soon realized that Pinkie Pie was jumping in a perfect circle right around her, trapping her in a circle of pink adorableness.

“But why aren’t you coming, I ask you?” Pinkie said, turning her head to face Rarity as she went around her without missing a beat. "You love spas and spas with friends!"

“Well, I have to finish a dress that it’s taking all of my time. I’m trying to make it look luscious but not tacky. I can’t decide if there’s too much pizzaz or too little, you know what I’m talking about?”

“I only know that pizza is best with blue cheese, but I understand. I was hoping we were going to be spa buddies but you couldn’t let it go to waste, isn’t it?”

“Of course I couldn’t.” Rarity moved her hoof and was relieved when Pinkie Pie stopped her dance of joy to let herself be given a friendly pat on her shoulder. “And we all know you also deserve some rest. Am I right?”

Pinkie Pie grabbed her foreleg and pulled Rarity in a tight embrace. “Don’t worry, I’m going to have fun for us both!”

“I know that.” Rarity sighed and just hugged her friend back.

“Well, I guess I should get going! This spa won’t be be done by itself! And remember: Go blue if you have doubts!”

Rarity shrugged as she watched Pinkie Pie going away one small hop after the other. “Well, not only she made me hungry but now that I think about it, a touch of blue in that dress won’t hurt…I should ask Fluttershy about this.”

“Miss Pinkie, always a delight to see you here!” Aloe said as she came greeting the pink mare. Everypony in there, whether client or workers, waved back at Pinkie Pie.

“The delight goes double for me, especially when I see you and your sister! But then, it would be quadruple because I like you and her double the time and you're always two and I’m going cross eyed but I have a free spa treatment.” Pinkie’s head did start to spin but maybe it was just because the air was hot and there was a strong scent of massage oils everywhere. Pinkie still managed to show the spa pony her ticket.

“Of course. Miss Rarity told us about it. Shall I accompany you to the sauna, for starters?”

“Lead the way!” Aloe complied with a pleasant smile as the pink mare followed her bouncing happily on her trial. “Rarity was so nice and I would’ve really liked she came here too but she has to work, like, double the time and I really needed to unwind and it’s going to be so fun, even if I’m alone!”

Aloe let out a quiet laugh. “Now that you mention it, you won’t be alone. There’s another client at the moment.”

“Good! A sauna is fun while alone but better with company. Do I know her? Of course, I do know her: I know everypony! Do I know her well?"

“Miss Dash is also here! She started becoming a regular, as of recently. She just started her sauna treatment.”

“Dashie?! That’s great! I know her a lot! We can be spa buddies! She’s in my top five of my best friends ever! But everypony has the number one spot because how can you make me choose between them? It would be rude. Maybe I could put her in the first place for my best flyer friends.”

“You would make her a nice surprise. Enjoy and relax!” Aloe smiled and handed her a towel before opening the sauna door. Pinkie Pie happily trotted in as the spa pony went to serve some other client.

The pink mare hummed a silly song as she wrapped a towel around her head as she walked inside, searching for the pegasus, excited and glad to meet Rainbow Dash and have a nice, pleasant vapor bath with her friend. They would’ve gossiped, had a hoofficure together later, talked about stallions and mares, why not? Also, she would’ve invited her to Sugarcube Corner to make her try that perfect new recipe. What Pinkie knew was that this was going to be a perfect day!

“Hello Rainbow Dash my spa buddy of the d-whaaaaaaa’?!”

She found Rainbow Dash, alright.

She was the only pony in there and, to be fair, Pinkie Pie liked it that way, given the situation. She had her hindlegs spread and sported a massive, rock hard and obscenely throbbing erection between them. It was a huge, veiny tube of black flesh, sharply distinct from her blue fur. It looked almost like a toy attached to her crotch as a prank, a notion dispelled as Pinkie also saw a couple of full, plump blue balls hanging just below it. “Oh...Hi, Pinkie Pie.” Rainbow said completely nonchalant about it. She waved her hoof at her and lightly jiggled her hips to make her...Big Dash say hello as well. “Like what you see?”

“Uuuhhhh…” Pinkie Pie tilted her head, unsure on what to think about the massive horsecock that her friend was sporting proudly, like it was the most normal thing in the world. Even if it was half erect it was so thick and invinting. “Hi.”

‘’Sup?” Rainbow Dash just shrugged, like it was the most normal thing in the world to do.

“How are you?” Pinkie tilted her head, trying to remember if that was supposed to be the norm. She really needed to ask Twilight some anatomy lessons one of those days.

“Awesome. As always. You?”

“You know, I don’t say this very often, but what the hay? That is weird!” She pointed at Rainbow’s throbbing sex, therefore stopping to ignore the elephant in the room. Or the massive stallion part as it was the case. “I think there’s a funny story behind it!”

“Well, uh…” Rainbow laughed and scratched the back of her head. “You promise that this doesn’t come out of this room?”

“I Pinkie Promise, Dashie!” She trotted happily towards Dash and sat next to her. “I’m all ears. I mean, I’ve seen plenty of weird things. I’m not judging you.” She looked at her with an expectant smile and happily kicked back and forth her hindlegs, ready to listen to Rainbow's explanation like a filly sitting at a campfire. Rainbow Dash looked even more relaxed as Pinkie didn't even make a scene about it.

“So, I was there at Twilight’s. She had the new Daring Do book and I asked her if I could borrow it...For a few months. She went to pick it up and then had to check something else in another room. Probably a new spell or something. Then I saw a bottle of cider on a desk nearby and...spoilers: It wasn’t cider. I found out right after I drank it...” Rainbow let out a nervous chuckle. It was clear she wasn’t proud of that one.

“Awwww, I wanted to guess that on my own! Maybe it could've been pineapple juice.”

“In my defense, it did look a lot like cider and it’s very hot today. Can you blame a girl for wanting a drink?”

“You could’ve have, I ‘unno, asked her a drink? And then she’d have said ‘No, Rainbow! That’s a magical cock growing potion, don’t drink that!’ and there. Done it.” Pinkie Pie patted her hooves together as she stated the simplest solution.

“Well, maybe.” Rainbow chuckled. “That’s the most straightforward thing I heard you say.”

“Well, duh! Sometimes you need it and your friends need to give you a straightforward answer. I’m not a one trick pony. I’m a five hundred trick pony!” Pinkie blinked. “Does it feel weird?”

“A little. It was a pain to walk with this thing here but I got used to it.”

“Can I ask you a question, Dashie?”

“Shoot.”

“Why did you even go to the spa if you had a big rocking boner? I mean, weren’t you afraid somepony would see it? Like me, for example? Not that I’m complaining, I’m just curious. What if somepony else a lot more close minded saw it? Or Fluttershy? Not that she is close minded but she’s a sensitive pony! I mean, not every day you see your best friend sporting a massive dick like nothing.” Pinkie Pie did lower her head to get a better look at it and it was indeed a marvel. A huge, throbbing, leaky mare-cock; like the ones somepony would’ve seen in those movies that nopony would’ve have admitted to actually see. And Pinkie saw quite a lot of them.

“Well...I was hoping the sexy twins would see it when I got completely hard. And then I would score with both of them.”

“Oh, Dashie, you scamp!” She gave Rainbow a playful bump on her foreleg. The two mares both laughed with mirth as Rainbow massaged the pained spot. “You’re terrible! But you have fine taste! This is just between you and me but I think they are very cute, too! But now that I think about it...Uhm…”

“What is it, Pinkie?” The two locked their gazes together, Pinkie Pie scooting towards Dash, close enough to touch her hips with her own. A sly smile appeared on her lips, mirroring the rainbow maned athlete’s own.

“You do have one mare quite willing to try right here…you’re okay with trying it with just one mare, right?” She realized that this was going to be a fun day, after all...Something that was going to surpass her wildest dreams...

“Really? And where is she?” Rainbow Dash leaned closer, apparently not minding Pinkie’s hoof resting nonchalantly on her huge member. In fact, she rested her own hoof on Pinkie’s, pushing it to follow the line of her generous girth.

“Right here…” Pinkie Pie leaned closer and locked her lips with her Rainbow Dash, slipping in few inches of tongue as the two filled the silence with the sweet noise of sloppy kisses. She felt Rainbow’s wet mane sticking to her own forehead as she pushed closer, hungrily and yet gently pushing herself on top of Rainbow Dash. She trapped the mare’s throbbing cock between both of them and started body sliding on it, caressing it with her soft tush and driving Rainbow insane with pleasure already. Her organ was extremely hard and sensitive to the pink pony’s advances and distracted herself by grabbing Pinkie’s cheeks and diving in with a deep kiss, starting an impromptu wrestling match with her tongue. Pinkie Pie was a sloppy, uncouth kisser and Rainbow loved it as the pink pony caressed her lips with her tongue, playfully biting it as they resumed pressing their tongue’s against the other.

“Oh, yes...It’ feels funny…” Rainbow broke the kiss and close her eyes, steeling herself from head to hooves as she felt a sharp, tickling sensation at the base of her dick. Pinkie moved and noted with delight that Rainbow had spurted her first drop of cum. She cleaned it off with her hoof and brought it to her mouth, tasting the bittersweet liquid with the tip of her tongue.

“Oh, I’m so glad you stopped before you blew your whole load!” She cooed as she covered in delicate kisses Rainbow’s neck, tracing a line towards her chest before following the cute curve of her belly. “Because now the real fun is starting…” She took between her warm hooves Rainbow Dash’s virility and started stroking at it slowly and deliberately. “You like it?”

“Heck yeah if I do. Now do your best, Pinks.”

“Like this?” Pinkie Pie started stroking it faster, landing a few kisses on Rainbow’s tip. She shared the warmth of her soft lips, never breaking eye contact with her praise expecting blue eyes.

“Oh, yes...That’s the stuff…” Rainbow grinned as she felt pleasure mounting in her generous lengths the moment Pinkie landed her
first lick. She played with it like a pro: Not just gobbling it with her mouth and licking it up, but treating it. She kissed it like mother would kiss a foal’s booboo and landed her tongue in strikes so thorough, so felt up and sincere, one would think she was swallowing up a lollipop. Not to mention her perfectly warm hooves that kept the raging boner in place and in the most caring, soft place they could be in. Pinkie Pie opened her her mouth to test the water, experimenting with Rainbow’s monstrous girth to find a better way to fit it into her mouth.

“Mhhh...This is puzzling…” Pinkie said as she covered Rainbow’s entire glans with her wanting mouth before pulling it back out from it. She looked at it like a toy without instructions as she jiggled it around. Rainbow tried to keep calm as her sex was still extremely sensitive at every simple touch. “How should I do it?”

“Well, maybe you can skip that part if it doesn’t fit.”

“Maybe, but how would I get you off, then? Also, now it’s a matter of principle! A challenge! Would you back out of a challenge?”

"Nope.” Dash chuckled and shook her head. "Glad you think that as well."

“Maybe I can try something like this…” Pinkie Pie took a deep breath and opened her mouth to the max. Outfitting that huge thing alone was going to be difficult, but Pinkie Pie was willing to try. She deepthroated the enormous thing in one fell swoop and instantly felt it touching the back of her mouth. Pinkie’s eyes widened and sported two small cartoon hearts at their center. The taste was mind blowing and it filled her mouth perfectly. She felt a strange tingle down her in her nethers and felt she would've come just by holding that broad cock in her mouth.

Rainbow relished in the sloppy, wet sensation of Pinkie’s most inner parts delighting her, being 100% there and caressed her mane, hanging onto it to never keep her from leaving. Pinkie Pie started pulling in and out of her mouth Rainbow’s cock, her soft cock slobbering all over its length, caressing every sensible nook and cranny of the sensitive appendage. She helped herself with her hooves, that never left the thick surface, and her lips, soft petals that enticed and stimulated Rainbow’s new, wonderful body.

The pegasus rode the wave as she felt wonderful pressure building up slowly in her loins. Adrenaline raced through her veins as she started facefucking Pinkie Pie who didn’t slow down a bit: She took everything the pegasus had to offer with a smile on her face. Pinkie Pie found Rainbow’s taste impossible to resist and impossible to give up. The pink pony used her tongue at the best of her ability as Rainbow let out a howl of pure pleasure as she felt her quick tongue going up and down the entrance of her urethra. She bit her lip as she spurted some more precum, prelude to something great and wonderful, as she wanted that sensation to last as long as possible.

Pinkie looked up and noticed her pegasus friend was getting closer, so like a truly crafty minx took more and more inches in and out of her mouth, slamming Rainbow’s girth in the back on her mouth. She rubbed every inch of Rainbow’s cock in every corner of her mouth, her lips firmly sealed across her length as she started fondling Rainbow’s balls, trying not to giggle as she made them comically bounce back and forth as she rubbed them faster with a hoof as she kept going.

“Pinkie...Get ready!” Rainbow whipped her cock out of Pinkie’s mouth and the pink pony didn’t give up the chance to lick its entire length one last time with a wet, slurping noise. She stood there with an open mouth as Rainbow jerked herself off and her whole body froze in shock as ultimate pleasure overwhelmed her. Her balls churned out and her whole length shook and trembled as it shook a thick, warm gusher of tasty cum right inside Pinkie’s mouth. The pink pony didn’t miss one drop of it as she gobbled on the precious ambrosia. She wanted to fill her whole belly with that warm, salty wonder that her friend was so generously giving her. Shot after shot, Pinkie Pie felt full and swallowed every thick drop with a satisfied moan.

Rainbow Dash fell back on her seat and gave herself a few seconds of rest, her chest heaving up and down as she felt absolutely wrecked but satisfied. She opened her eyes to look at the ground and noticed there were just a few stains of cum. Rainbow was strangely relieved that they didn’t make a mess. But that would’ve been short lived as she noticed she still was quite erect…

“Mhhh! That was juicy!” Pinkie liked her own face with her overly long tongue. “A bit salty but not bad. That potion is high quality, I tell you! In fact, I’d like to try it one day! But why do you think Twilight created something like that?”

“I ‘unno. Maybe she needs a dicking for one lonely Saturday Night?”

“Or give a dicking.”

“True.” Rainbow laughed at the thought of Twilight actually being a top and giving some rowdy mare a good, hard night of pounding. Not for Twilight herself, of course, but the scenario was just surreal.

“You know who else needs a dicking?”

“Youuuu?” Rainbow wiggled her eyebrows as she took off, slowly prancing her way towards the pink mare.

“Whoah, did ya read my mind? Quick, tell me what I’m thinking about right now!”

“About the dicking I’m going to give you?”

“Wow. We can make so much money out of this! Now, sex me hard!” Pinkie Pie turned and lifted her tail, showing her puffy, wet pink prize. Rainbow rubbed her hooves and licked her lips, shivering in pleasure. If Pinkie’s mouth was so great, the rest would have to be pretty amazing. She grinned as she caressed the sweet curve of her butt and gave her a small slap on it. “Wow, you’re rough! I love it!” Pinkie Pie lifted her butt and waggled it at Dash, leaving her drooling at the wonderful spectacle. Her member liked that too, as it happily overflowed with cum. Rainbow’s felt her chest trembling her pleasure, her heart beating hard on her ribcage and felt butterflies in her stomach. She had to take that mare. Right there. Right then. On that floor.

Rainbow Dash stood on her hindlegs and grabbed her penis. Both of them winced the moment she brushed her sensitive tip against Pinkie’s velvet folds. For all of her bravado, she never ever tried something like that. She stuck with her own genitals. “Ready?” She said.

Pinkie Pie nodded and licked her lips. She turned to get a oh so sweet glance of Rainbow ready to jam herself inside her before, with a slow thrust of her hips, Dash slipped inside her. Pinkie Pie moaned as she filled her hungry folds with her wide girth. Pinkie Pie let out a silent moan of pure pleasure as she was filled, slow inch by slow inch, by the biggest, thickest cock she had ever felt. Not that she had that many cocks to begin with but Rainbow was her own class. Rainbow knew how to use it and didn’t apologize for it. Even if she just got that for less of a day, Rainbow Dash had a knack for improvising. Pinkie’s whole body was quaked as Dash went rough on her, without mercy and without subtlety. She even ripped the towel out of Pinkie's head in the heat of the moment, so she could take at her beautifully loose mane. She took a good whiff of her scent as she kept plowing her, reveling with her sense of touch of the pink pony's body.

Rainbow's passion had a purity on its recklessness that Pinkie found amazing as Rainbow fucked her without mercy, squeezing her flanks firmly. The blue pegasus was a roaring, humping machine, mounting her like she was possessed and Pinkie Pie felt pleasure unlike any other as she felt her inner walls being spread. She felt a little uncomfortable as Rainbow was as big as it got but she was finding her pace and growing more accustomed to her friend’s big virtue. It stopped feeling like she was splitting her in half. She giggled to herself as she realized that Rainbow Dash did everything big...Or had it big!

Rainbow showed her tender side as she gently wrapped her forelegs around Pinkie’s waist and eased herself in by kissing Pinkie’s back and reaching for her cheeks. Pinkie Pie blushed as she felt that wonderful contrast of tenderness and reckless fucking. She felt herself safe and satisfied in Rainbow’s embrace as the pegasus rocked her world. Rainbow was going absolutely crazy, though: She felt up Pinkie’s hole and she loved what she was having. She was wonderfully tight and her insides felt so good. Her already sensitive member due to Pinkie’s sweet lip work was getting itself a treat, tucked in Pinkie’s warm, juicy folds. They wonderfully wrapped itself tight around the entrance of her cock as she slammed it in over and over again.

Rainbow passed her hooves on Pinkie’s belly as the pink mare’s legs shook under the increasing pressure in her body. Rainbow felt her up and chuckled warmly.

“What’s that, Dashie?”

“It’s a bulge…” Rainbow could feel her own movements just with the touch of a hoof.

“Uh?”

“I’m so big you have a bulge…”

“Should we be worried?”

“Does it hurt?” Rainbow immediately slowed her pace. Pinkie Pie grabbed one of her hoof wrapped around her very real bulge and smiled gently, even though Dash couldn’t see it.

“Nope. I’m loving it so much.” Rainbow burrowed herself further inside, wriggling her hips left and right.

“Want some more?” Rainbow Dash grunted and pushed, slapping her balls on Pinkie’s derrier.

“Step up your game, Dashie!”

“On it!” With that, Rainbow lifted Pinkie Pie from the ground and let herself literally fall on her cock as she let gravity do most of the job for her. Pinkie Pie giggled and rolled her hips faster, letting herself be impaled by Rainbow’s cock and being penetrated in a better, narrower angle. She could finally see her engorged belly and she felt oh so ready to have it swell a little more with Rainbow’s tasty spunk...

Rainbow wrapped her forelegs around Pinkie’s tummy and pumped up and down, amping up her game as she penetrated her lover to an even narrower angle, perfectly socketing her plump dick. Pinkie Pie was a fantastic cock warmer and the way she was using her hips to ride her while she mashed her own forward in perfect harmony with Pinkie Pie. Her cock slammed itself upwards, hitting Pinkie Pie in her sweetest spot. She stepped up her game, all right, bucking her so hard until she could feel Dash's member engorge and harden even further and finally pumping her full of Rainbow’s hot spunk. Pinkie Pie writhed in pleasure as Dash emptied, warm shot after warm shot, her plump balls right in Pinkie’s womb. Shot after shot inflated her belly with Rainbow’s hot cum and the pegasus moaned like a possessed mare, absolute pleasure striking her body in every way. She could feel Pinkie's delicate walls cling onto her rod, massaging it to milk every single drop of cum out of Rainbow Dash. Just as she loved it. She could feel every shot of warm cum running trough every inch of her lenght. She kept going until she filled Pinkie’s belly with every last drop of her cream and her half flaccid cock popped out of Pinkie’s snatch of its own. Huge drops of her seed came out of her slit and splattered on the floor with a loud, wet noise like somepony was dumping a bucket of jelly on it.

“Holy crap…” Pinkie Pie said, her head still spinning from the powerful orgasm, every cell of her being riveting with joy. It was one of those sensations that actually struck in a sharper way after the event. “That was amazing…”

“Glad you liked it. I really liked it, too. In fact, I loved it...We should do that, like, every day!” Rainbow Dash chuckled as she landed a few delicate kisses on Pinkie’s neck as the two cuddled on the floor. She was visibly exhausted and her breath came out in sticky globs as she kept laughing, her snout buried in Pinkie's poofy mane. She felt a strange warmth in her chest, a rush of energy and joy. “So...Crap, I realized something right now.”

"What's that?"

“How can we explain this mess to the twins?!” Rainbow looked at the cum covered spa floor. Her semen was still oozing out of Pinkie’s snatch.

"Oh, shoot...Well, leave it to me. I’m sure I can come up with a good excuse.”

“I may have costed us that free spa treatment…” Rainbow Dash looked down at their mess. “And any other spa treatment ever. If you’re lucky we’ll be the ones cleaning this stuff…”

“Leave that to me. I’m sure I can come up with a perfectly reasonable explanation for—”

"Miss Pinkie? We are ready to continue your treatment!" Suddenly, the twins opened the spa’s door and saw the the scene, their eyes widening with surprise at the unusual sight of two mares both relaxing post coitus and one of them sporting a very unmare like equipment. “Miss Pinkie?! Miss Dash?! What is happening here? What is this mess? What have you done here?”

“Uuuuuuuuuuuuuuuuuuuuuuuuuuuuhhhhhh…” Pinkie Pie then realized the two of them were still on the floor and exposing their once very busy privates. Pinkie realized she had just the time to improvise “I have an explanation! An explanation I have prepared and it’s perfectly sensible and I’m not stalling at all even if it sounds like I’m doing it this very moment! And the explanation is—”

“And why didn’t you invite us in?” The twins winked at each other and flashed a seductive look at the two as Aloe closed the door behind them again, nonchalantly kicking it with her hindleg. Rainbow Dash got hard again as soon as she saw those pretty flanks coming towards her.

“Told you I was getting lucky today.” Dash said with a chuckle as she got up, sporting another, bigger than before, erection.

“Oh, you’re still a scamp! But the best kind of scamp! Can I join, too?”

“Well, duh!”

The three other ponies said at the same time as they prepared to make an even bigger mess...
