Party Time!
“Pinkie, why did I have to drink that weird potion at Zecora’s house?” Rainbow Dash sighed, feeling irritated as she opened the door to Pinkie’s room. “Couldn’t we have waited until we got back?”
“Of course not, silly,” chirped Pinkie Pie, bouncing past Dash. “We had to know if it was working or not.”
“Well, it’s working alright,” said Rainbow Dash. To emphasize her words she raised one of her hind legs, revealing her new appendage while staring at Pinkie with an unamused glare. “Do you have any idea how hard it is to walk with this thing?”
“Well, I didn’t think it was going to be so excited,” answered Pinkie Pie with a grin, her cheeks growing into a darker shade of pink as she stared at the throbbing length. “But it sure looked fun!”
“Oh really?” said Dash and her angry glare broke up into a sly grin as she kicked the door shut with her back hoof. “Then how about we continue the fun and give this bad boy a test run?”
“Well, duh, that’s the whole point,” Pinkie turned around and raised her ass towards Dash. “The love tunnel is ready for entry!”
And it sure looked ready. Pinkie’s lowers lips were puffy, glistening wet and so swollen with anticipation that they had grown a couple of millimeters. Each time the lips winked, opening and closing themselves in front of the gaping tunnel, thick juices slowly dripped down onto the floor beneath the pink pony.
Dash couldn’t turn her eyes away. Had Pinkie always been this hot? Or was this another effect of the potion? Dash’s questions were soon forgotten as she suddenly caught the musky scent of Pinkie’s sex. The smell seemed to fill her mind, making her stop caring about such trivial things, while her new toy throbbed and twitched in excitement.
She tossed the bag with the additional potions onto Pinkie’s couch before finally grabbing her pink friend’s soft buttocks. Thinking that she wanted to punish the pink pony for making her walk through entire Ponyville with an erection worthy of Celestia, Dash began to knead and squeeze the ass in front of her.
Pinkie gasped as her buttocks was suddenly baked like dough.
“Dashie, stop teasi- gah!”
Pinkie’s protest was cut short as Dash suddenly lowered her head and dragged her tongue over her friend’s swollen sex, tasting the pink mare's sweet juices. Hearing how Pinkie gasped and moaned as she was licked made Dash’s own arousal grow ever stronger. She pressed her tongue against Pinkie’s clit and was surprised at how hard it was. Did this really turn her on so much?
“Pinkie, you don’t usually get this turned on,” said Dash and playfully gave the clit another lick. “Is it because of my new 'friend' here?”
Dash stood up on her hind legs and placed her thick length on top of Pinkie Pie’s buttocks, giving one of them a small slap with the flared head.
“Y-yes,” gasped Pinkie and pressed her ass against Rainbow Dash. “That… and I might have…guh… taken one of Zecora’s potions… too.”
“Wait… so you’ve been this horny all the way back from Zecora!?” exclaimed Dash.
“Kind of,” admitted Pinkie and gave Dash a sultry smile while pressing a bit harder against the cyan mare.
“Ha, then I’ll make you come in ten seconds flat!” teased Rainbow Dash and suddenly pressed one of her hooves against Pinkie’s dripping snatch.
“Oooh, Dash!” moaned Pinkie. “Do it… faster!”
“Faster is my specialty!”
The pegasus began to move her hoof up and down in a very fast pace while pressing it against Pinkie’s sex. The hoof, coated with the pink mare’s slimy juices, flicked against the throbbing clit with each stroke.
“Aaah! Not… that fast, Dash,” moaned Pinkie and dug her hooves into the carpet below. “You’ll make me- ah!”
“Did you say faster?” teased Dash and grinned as she sped up her motion. “I’m the fastest pony in Equestria, remember?”
Pinkie didn’t answer. Instead, her entire body tensed up, her hips raised themselves even higher and with a high-pitched scream she emptied her juices all over Dash’s hoof. Her pussy convulsed in pleasure and juices gushed out like a fountain, drenching the floor, before her body fell down into a shuddering heap.
“Woah!” yelped Dash in surprise and took a step back. “I didn’t think you’d actually cum in less than ten seconds.”
Pinkie slowly stood up and gave Dash a wide smile.
“Now it’s my turn!”
“Your turn? Wait, what!?”
Pinkie suddenly launched at Rainbow Dash, knocking her to the ground. Dash hit the floor with a loud *thump*, her wings sprawled out beneath her, while Pinkie quickly grabbed the fat member with her hooves.
“Hold on, Pinkie, and let me catch my breat- Ooohuuugh!”
Rainbow Dash threw her head back in pleasure as Pinkie gave the sensitive tip a long lick.
“Tastes like rainbows,” said Pinkie while licking her lips. “With a hint of salt.”
“You’re not going to… eat it are you?” asked Dash a bit worried, as she never quite knew what her pink friend might do.
“Sure am!” exclaimed Pinkie before shoving the flared head into her mouth.
Before Dash could stop the pink pony, Pinkie Pie had already begun to quickly swallow more and more of the thick cock down her throat. Suddenly, the blue mare felt something stirring in her loins and a few seconds later her member grew even bigger. Pinkie spat out the growing length, coughing and gasping for air.
“If you plan to grow like that you got to tell me,” said Pinkie.
“I… I didn’t know it was going to grow!” answered Dash irritated. “Didn’t you read the label?”
“What label?” said Pinkie while staring questioningly at cyan mare.
“The label on the potion!” yelled Dash even more irritated.
“Oooh, that label!” exclaimed Pinkie and stood up.
She quickly made her way to the bag on the couch and began to search through its contents until she found the empty bottle she had used on Dash. She stared at the label a long time before opening her mouth.
“What does; ‘three drops only’, mean?”
“PINKIE PIE!” screamed Dash. “You made me drink the entire bottle!”
Before she could continue scolding Pinkie Pie, Dash felt the stirring in her loins again followed by her member growing even larger and thicker. The fat veins coiling around the shaft seemed to pulse in rhythm with Rainbow Dash’s heartbeat. The growth didn't slow down until at least 25 inches of thick horse-meat throbbed between the blue mare's trembling legs.
“Oooh, I’ve never seen such huge cock before!” said Pinkie gleefully and quickly grabbed hold of the throbbing length again. “Don’t worry; I’ll fix this, Dashie! Trust me.”
“I was afraid you’d say,” answered Rainbow Dash but Pinkie ignored her and quickly pressed her mouth against the flared head, which was much bigger than last time.
A few slobbering attempts later, the head finally found its way into Pinkie’s welcoming mouth. The pink mare’s cheeks bulged out from the sheer thickness of the flared head alone.
“Ah… that feels… awesome!” gasped Dash and laid down on her back. “You’re a natural at this, Pinkie. I had no idea… it would feel this good. I should have gotten me one of these things long ago.”
Pinkie pushed her tongue up against the cock in her mouth, moving it around while sucking, before pressing her head forward. Dash perked up as she felt how Pinkie tried to swallow even more of her member.
“W-wait, Pinkie!” Dash put a hoof on the pink mare’s forehead. “Stop, you featherbrain, that’s impossible! It’s too big now!”
Pinkie let out a gurgle, supposedly a giggle, and quickly shoved her head forward. Dash, overwhelmed by the new sensations, fell backwards onto the floor and gasped in pleasure as her member was forced into Pinkie’s gaping maw. The pink mare continued to shove more and more of the fat cock down her throat, not stopping even as her throat bulged out. Spit and foam began to gush out between her lips as she went past the medial ring. Wrapping her front hooves around Dash’s waist, Pinkie pie forcefully pressed down the rest of the length into the throat, gagging and coughing along the way, until her snout hit the cyan mare’s abdomen. Then, she quickly ascended, drawing the entire length out of her gaping maw, before diving back down and slamming the cock into her slimy throat. This time the cock went in much faster, lubricated by Pinkie’s spit and saliva. Even though she was gagging, Pinkie didn’t let up her violent blowjob. She bobbed her head, faster and faster, until she was going up and down the thick cock like a piston, her throat bulging out each time the fat member squeezed inside. Her fast and rough motions made her saliva fly in all directions, drenching her own face.
At this point Dash was screaming and thrashing around in pleasure, her mind going blank every time the pink mare moved her head. She bucked her hips into Pinkie’s face, feeling how her friend’s throat clasped and squeezed around the member like a vice. After only a few minutes of Pinkie’s violent face-fucking, Dash felt a strange pressure build up inside her. The pleasure quickly grew stronger and stronger as the pressure rose and spread towards her cock.
Rainbow Dash had no time to warn Pinkie of the impending orgasm before she fell into a blissful abyss, her mind going blank and her vision turning white from the unearthly pleasure that now coursed through her body.
Pinkie stopped her piston movements as she felt how the cock suddenly throbbed violently and how the flared head swelled up, pushing right at the entrance to her stomach, before a flood of semen poured down into her bowels. Pinkie held her head pressed against Dash’s abdomen for as long as she could, taking more and more semen into her stomach, until her lungs screamed for air. With a jerk of her head, Pinkie dragged the horsecock out of her throat in a single movement. Gagging and gasping for air, the pink pony fell down onto the floor beside her cyan friend, while the cock covered them both in its last spurts of cum.
“*Cough* That was… *cough* … so much fun!” panted Pinkie while placing a hoof on Dash’s chest, playing with some of the semen that had hit the pegasus. “Did it feel good?”
“It felt… too good,” answered Dash, while stroking her forehead that was slick of sweat. “Do all stallions have these kinds of orgasms?”
“Of course not,” giggled Pinkie and gave the semi-hard member a playful tap before locking eyes with Dash. “I would only give this kind of pleasure to you, Dashie.”
Rainbow Dash felt how she began to blush under Pinkie’s intense gaze and quickly shook her head.
“Enough of this mushy stuff,” said Dash as she stood up. “I can still go for another round.”
“He he he~… My love tunnel is still waiting for its cream filling.”
Dash grinned and, wanting to take the lead, tried to push Pinkie onto the bed but it seemed like the pink mare had other plans. She quickly stepped to the side as Dash tried to push her, and attacked as the pegasus tried to regain her balance. They tumbled onto the bed, the springs creaking under their combined weight, and Pinkie landed on top of Dash with a small *thud*.
“Hey, no fair!” protested Dash. “I wanted to be on top!”
“Sorry, but first I’m going to give you the P.S.S.R.R.F.R!” said Pinkie while gently bouncing on top of Dash, playfully grinding her wet snatch against the underside of the still rock-hard cock.
“What the hay is P.S.S or whatever you just said?” asked Dash and raised an eyebrow at the pink pony on top of her.
“Pinkie’s-special-super-rough-rollercoaster-fuck-ride,” exclaimed Pinkie with a grin.
“I think you need a better name for it,” mumbled Dash as Pinkie lowered her head towards the cyan mare.
“And what would that be, Dashie?” whispered Pinkie, right next to Rainbow Dash’s ear, before giving the pegasus a gentle kiss.
“I… uh… i-it’s f-fine… I suppose,” Dash stammered, blushing so intensely she wondered if her cheeks had turned on fire.
“Great!” said Pinkie as she stood up over the blue mare, aligning her wet hole with Dash’s throbbing member.
“All aboard the rollercoaster! Are you ready, Dashie?”
“Uh-huh,” nodded Rainbow Dash without breaking her sight with Pinkie’s drooling slit.
“Then… here… we… GO!” yelled Pinkie and proceeded to thrust her hips down, shoving the flared head against the tight opening of her slit.
At first, the cockhead simply prodded the opening despite Pinkie’s efforts, until the pink pony slammed her hips down as hard as she could. The fat head, coated with the slimy juices that spilt out from the drooling cunt, drilled itself against the tight opening before slipping insidet with a wet *plop*. Pinkie’s hips came to a stop as soon as the cockhead plopped inside, the fleshy walls straining around the thick shaft as they tried to confine its well-endowed size.
“Oh whoozie!” panted Pinkie with a satisfied smile. “You sure is big, Dashie!”
“Well, that’s your fault, you know?” answered Rainbow Dash.
“Then… I better take responsibility, right?” continued Pinkie and began to move her hips once again.
The pink pony had to use all her strength to force the giant cock any further and, despite the fact that it should have been impossible, the fat and throbbing meatpole was slowly but surely pushed inside. Pinkie used slow but strong thrusts to squeeze the shaft deeper into her constricting snatch, the clasping pussylips swallowing the vast member inch after inch. It even went past the medial ring, which pushed through the strained opening with another loud *plop*, before the flared head met a barrier.
Dash gritted her teeth as she felt her cock being squeezed like a vice inside Pinkie’s deepest reaches. Slime and mare juices coated the member, making it slick and wet, as it throbbed in time with the cyan mare’s heartbeats. Some of the gooey juices dribbled out around the veiny cock, forming a small puddle on top of Dash’s abdomen, as Pinkie suddenly shifted her weight.
“The rollercoaster is primed and ready,” giggled Pinkie Pie while placing her front hooves on top of Dash’s chest in order to get a better angle. “One rough fucking starting in three… two… one!”
As soon as the last number had left her lips, Pinkie raised her hips, dragging the member out of her slobbering snatch until only the head remained inside, before slamming her hips down against Dash’s own. The fat head instantly crashed against the pink mare’s cervix like a battering-ram, sending waves of pleasure to both ponies. Rainbow Dash arched her back and tensed her muscles as Pinkie raised her hips for another thrust. Slamming down once again, Pinkie shouted in delight as mare juices squirted out from her swollen slit and splashed across Dash’s chest.
After a few hard thrusts Pinkie was confident that the meatpole, which was currently impaling her, was wet enough. The sound of her wet hips smacking against Dash’s own brought a satisfied grin to her face.
“Time to go to phase two!” declared Pinkie while panting, her fur already glistening of sweat. “Rollercoaster piston-fucking engaged!”
“Augh, Pinkie!” gasped Rainbow Dash. “You’re... too good!”
Pinkie instantly sped up her thrusting, forcing the member in and out at an incredible speed. The slime made the cock slip in and out with no problem despite the overwhelming tightness. Each time Pinkie thrusted she made sure that her hips slapped against Dash’s and that the flared head bashed against her womb like a jackhammer.
Each time the cocktip hit the bouncing mare’s cervix it sent waves of pleasure through Dash, each being more powerful than the last. She panted heavily, digging her hooves into the sheet and flexing her muscles as Pinkie rode her like a simple fucktoy.
Suddenly, Pinkie slammed down one last time before stopping, looking down at Dash’s thick cock in surprise. Somehow the cock had grown during her violent humping, as almost five inches of slime-covered horsemeat separated Pinkie’s reddened pussylips from reaching the cyan mare’s muscled abdomen. The pink pony grunted as she slammed down again, trying to take the newly grown inches, but her already overly stretched pussy was unable to contain the new length.
“I don’t think that will work, Pinkie,” said Dash as the pink pony slammed her hips down yet again. “It’s impossible. Not even your cunt can take that much!”
“Oh, really?” said Pinkie with a sly grin as an idea formed in her sugarcoated brain. “We still haven’t tried the rest of the potions we got from Zecora!”
Pinkie rose up, sliding the slimy cock out of her drenched snatch before bouncing off the bed, letting the fat meatpole slap against Dash’s chest as it was freed from its tight confines. She made her way over to the bag and dragged it over to the side of the bed.
“This one says; ‘Stretching’,” said Pinkie as she rummaged around amongst the potions. “That sounds fun, let’s try it!”
Before Dash had a chance to warn her, the pink pony had already emptied the flask into her mouth.
“Uh… how do you… feel?” asked Dash as she eyed Pinkie with concern.
“Horny,” answered Pinkie with a smile as she quickly jumped up onto the bed, spreading her legs and once again aligning Dash’s throbbing dick against her winking pussylips.
With a small squeal of delight, the pink pony swallowed the bestial shaft, inch by inch, as her hot and slimy pussywalls quivered around the thick member. This time the cock seemed to make its way through Pinkie’s pussy much easier. As Pinkie reached the five inch mark, Dash felt the fat tip of her cock pressing against the soft and swollen, yet firm, barrier once again.
“Preparing to drill!” Pinkie raised her hips until only the flared cockhead remained inside. “In three… two… one… GO!”
The pink pony jumped up, using her entire body weight as she slammed down on Dash’s dick. With just one shove the cock reached Pinkie’s cervix again, bashing against the tight barrier like a sledgehammer. Dash’s screamed out in pained pleasure, but Pinkie had no plans to stop. She continued to press her hips down with all her might, sweat rolling down her fur, as she put more and more pressure on her cervix until it finally caved in. The flared head slowly forced itself through the tight barrier as the pink mare pushed down harder and harder. With a loud scream, Pinkie shoved her entire weight down and forced her hips to slap against Dash’s. The puffy pussylips smashed against the cyan mare’s muscled abs as the bestial shaft stretched the tight cervix fully open, the fat cockhead plopping inside the slimy womb. With a final, hard, thrust Pinkie slammed the tip of the beastial member against the backwall of her trembling womb. The cock stretched the uterus, making it bulge out from Pinkie’s abdomen.
Dash’s gritted her teeth as the cervix clamped down around the veiny shaft as if it was trying to crush it, trapping the flared head deep inside the pink pony’s uterus. The womb seemed to quiver and contract around the tip of the cock, sucking and milking the throbbing head like a pump, while the wet cunt squeezed and constricted around the rest of the thick horsecock with its fleshy and muscular walls.
“Told you I could take it!” grinned Pinkie Pie and rubbed the bulge on her abdomen. “Let’s resume the ride!”
Dash had no time to recover from the overwhelming sensation of entering Pinkie’s impossibly tight womb before the pink mare began to raise and slam her hips up and down in quick succession. Her thick shaft was forced in and out of the clasping snatch as slime and gooey mare-juices were squeezed out around the fat cock due to Pinkie’s violent humping. Dash jerked her hips up to meet Pinkie’s fast-moving hips, trying to match her friend’s fast-paced rhythm, but the sheer force of the pink mare’s thrusts made it impossible for Dash to even raise her hips before they were slammed back down against the bed.
Pinkie Pie laughed as pleasure coursed through her bouncing form. She pressed her front hooves against Rainbow Dash’s chest before picking up her already fast pace. She moved her hips in a piston-like motion, bashing the fat cockhead against the end of her womb with each thrust. Her abdomen bulged out several inches as the cock slammed in and out of her, her clit throbbing in pleasure as it pressed against Dash’s furry crotch every time their hips met with a loud slap.
Suddenly, Dash put her hooves around Pinkie’s waist, panting and sweating as the pink mare continued to ride her.
“I’m… g-going to… cum!” grunted Rainbow Dash before moaning loudly.
“Ahh, yes!” panted Pinkie Pie and giggled. “Turn me into a cream-filled cake!”
Pinkie pie sped up her thrusting even more, slamming her hips against Dash so hard that the entire bed shook from the force. The fat head hammered against the inside of her womb, the cervix clasping around the veiny shaft as it moved through the tight barrier like a piston. She moaned and gasped louder and louder as she felt how Dash’s throbbing horsecock started to swell inside her, straining her snatch despite the potion she took.
Rainbow Dash moaned together with the pink mare, still pressing her hooves against Pinkie Pie’s hips as the pleasure reached its peak. Dash screamed, arching her back and began to convulse as the pleasure completely overwhelmed her senses.
Pinkie joined Dash, screaming as loud as she could. Her hips kept moving in a blur until she felt how the head of the swollen cock flared up inside her womb. Gritting her teeth, Pinkie put all her strength behind a final thrust as she slammed her hips against Dash’s, making the beastly cock hilt inside her and forced the flared cockhead to crash into her uterus. As the tip of the member pressed against her innermost depths and stretching her uterus up against her guts, Pinkie screamed even louder as she orgasmed. The slimy snatch squeezed and milked against the thick shaft that currently impaled the pink mare before a fountain of gooey mare-juices shot out from her cunt and drenched Dash’s convulsing form.
As the cock was pressed against the innermost wall of the womb as hard as it could possibly be pressed, Dash rolled her eyes up in her skull before her fat member let loose a torrent of steamy sperm. The slimy cum shooting out from the spasming shaft filled Pinkie’s womb within seconds, bloating it and making it bulge out from the pink mare’s abdomen. As the pressure became too big, the cum slipped past the tight cervix and gushed out around the thick meatpole, splattering Rainbow Dash’s hips with her own hot sperm.
The dual orgasm lasted for several minutes, the fat cock pumping the pink mare full of sperm and bloating her flesh-cave like a balloon, before the two ponies finally came down from their blissful height. Pinkie Pie rubbed her swollen belly as she basked in the afterglow, smiling down at Rainbow Dash who lay panting and shuddering in a sweaty mess beneath her. The pink mare leaned forward and pressed her bloated form against her blue friend before giving Dash a long kiss.
“That was fun,” giggled Pinkie as she broke the kiss.
“That… was… a-awesome,” stammered Dash. “We should… totally do that again.”
“Totally,” repeated Pinkie, giggling and closing her eyes as she nuzzled her head against Dash’s neck. “And Dashie?”
“Yeah?”
“We still got more potions to try out.”
“… How many did you borrow, Pinkie?”
“33,” answered Pinkie with a smile before giving Rainbow Dash a kiss on her cheek.
Dash swallowed nervously, staring at Pinkie’s bloated belly, before her pink friend reached out with a hoof and turned off the lights.
