Petting Session

You were sat on the couch with seven mares wanting more of your unnaturally powerful dick. Your two and a half feet long cock was more than happy to oblige. Celestia’s massive ass loomed over you, casting a dark shadow upon you as she stood over you. Yours and her cum streamed down the thick canyon of her backside like a river.

Twilight squeezed herself through the middle of Celestia’s thick hind legs, climbed up onto the couch and lay down on your lap. Your thick cock was now hotdogging her soft, fat ass. Your hands came down to take hold of her rump, sinking into the soft flesh of her backside before meeting the strong muscles deep beneath.

Applejack sat down at your feet. Pinkie Pie sat down on your right and simply laid her head on your shoulder. Rarity on the left did the same.

Fluttershy and Rainbow, on the other hand, made to stand beneath Celestia, Fluttershy on the left, Rainbow on the right. The two lay one hoof each on her upper thick, hind legs. She took this as her cue to sit down so they could have better access to her ass. The two pegasi started to worship her ass, kneading the soft flesh of her cheeks, digging deeply into her thick rump.

Now with the rest in position, Twilight magically lifted herself onto your thick, mushroom-like tip with her horn glowing with magic. Your hands shifted down from her cheeks to under her ass to support her.

Your hands took a tight hold of her lovely plump cheeks, your fingers digging in deeply into the soft fat upon her cutie marks. Twilight smiled down upon you along with her beautiful purple eyes sparkling in joy, loving to see your hands were lovingly holding her cutie marks, which was the soul to her very being.

Twilight gave you a nervous smile. She then took a deep breath, before releasing her magical hold over herself, and thus your fat tip plunged into her tight pussy. The poor mare cried out in pain as she slowly took inch after inch of your massive cock inside her.

Your thick member pushed apart her wet, soft walls of her sex as she sank onto your monster cock. Tears fell down her cheeks while she hissed in pain as your massive invader shattered her virginity into smithereens as it did with Fluttershy. Twilight buried her head into your shoulder and cried silently.

You lifted your right hand away from her ass and placed your hand upon her mane. From there, you with loving tenderness pet her mane. Her hair was softer than silk roaming through your fingers. The mare trembled at your touch and made a series of muffled whinnies into your shoulder.

Eventually, your fat tip came to rest against her deepest barrier. Your cock, on the other hand, was not even taken halfway. Pinkie Pie and Rarity lowered their heads down and began to lick your cock just under Twilight’s pussy. The two moved their heads up and down your shaft. Applejack meanwhile started to kiss, lick, and suck on your balls.

Twilight continued to cry quietly into your shoulder for quite some time and didn’t move. You didn’t move either, you allowed the poor mare to take her time to adjust to your cock.

The mare lifted her head up from your shoulder to reveal her badly bloodshot eyes. She then leaned forward and took you into a passionate kiss. Your right hand went back down to her ass, and you took a tight grip of her right cheek. Your hand sinking deeply into her soft rear.

Pony and human tongues danced together in tender union, gently rubbing against each other and whirling about. Despite the fact, the pony had a much larger tongue than the human.

While still kissing you, Twilight magically lifted herself up by a few inches, before dropping herself down on your cock, which made her utter a muffled whinny in your mouth. She did this action over, and over again.

With the feel of your cock being licked and kissed, the feel of a lovely pony pussy, and the kissing of a beautiful mare. You were now quickly approaching the finishing line of your release.

With that, your cock painted her insides with your creamy seed. Twilight moaned aloud into your mouth and her cutie marks began to glow with a blinding light, which made everypony gasp in shock.

As her cutie marks glowed she started to grow in size. While she grew, her pussy was able to take more and more of your cock. The expanding cheeks of her ass pushed Pinkie Pie and Rarity aside.

Her tongue inside your mouth was threatening to suffocate you. Fortunately, Twilight pulled back and uttered a loud whinny as the growth continued to flow through her body.

Her ass came down with a hard meaty slap on your lap. You hissed in pain at her now great weight pressing down upon you. Twilight looked down at you with a sheepish smile. Her body now had grown to be about the same size of Celestia's. If that wasn’t enough, you could see a pair of feathery wings extended out from her back.

You marveled at just how much more ass you had to play with now. Twilight’s ass was now thick and bubbly. You roamed your hands over the wide expanse of her massive backside, applying a tight squeeze here and there. You sighed in delight at the feel of her ass conceding back like soft dough under your applied pressure.

You pulled your right hand back and gave her ass a hard slap. A loud meaty slap accompanied your strike upon her rear, along with a soft moan from her, which was music to your ears.

The mare giggled at your great assy antics. “Oh Anon, you really love my new big fat ass, don’t you?” You uttered a muffled grunt into her soft, furry chest. “I’ll take that as a yes.”

“Alicornation? Well, forget friendship lessons. Just get a human to fuck you.” said Celestia, looking at the strange events that took place in front of her.

“What if it doesn’t work with the others?” said Twilight.

“Only one way to find out.” said Applejack, turning around, dropping herself down and raising her ass high into the air.

You stood up off the couch and made your way behind Applejack. You placed your hands on her cutie marks, sinking about an inch into her plush rear, before meeting her strong apple-bucking muscles beneath.

“Make me a princess, sugarcube.” she said softly.

You thrust forward into her marehood, she flung her head back, moaning aloud. You grunted at the feel of her tight marehood as your cock went further and further into her.

You looked back to the others to see them not moving and just staring at you. You sighed sadly over the fact that the other half of your cock was not going to be tended by lovely pony mouths this time.

You pulled back, before slamming into her. You grunted at the feel of her powerful walls squeezing your member.

Your heavy, long, thick cock went back and forth into her. Applejack’s legs started to become a little shaky at the bombardment of your dick into her, while she uttered low moans.

On and on this continued for quite some time. But your release appeared to be nowhere near.

“Applejack, I’m not even close. I think I need some help.” you said.

“Ya… ya heard him. This... this fella... needs help.” said Applejack between breaths.

Celestia came to stand on your right, and the now larger Twilight came to stand on your left. Both turned around and presented you with their massive asses. The two then slowly walked backward, and smothered you on both sides with their huge asses, sandwiching your body between their massive ass and taking you into a world of darkness, the lovely scent of their marehoods drove you crazy with lust.

You uttered a muffled moan. Which turned into a muffled scream when you felt the others begin to kiss and lick your cock. You didn’t last very long after that.

With that, you came into Applejack’s pussy.

You heard the muffled voice of Twilight speaking. “Oh, good. She seems to be growing as well.”

You felt your cock take more and more of her hot marehood. You sighed in bliss when your cock came to rest against her deepest barrier. However, something strange started to happen, you now felt your cock beginning to slip further away from her deepest point.

“She’s still growing! Wooo!” shouted Pinkie Pie.

Your cock slipped out of her marehood. This was followed by Celestia and Twilight being pushed back as Applejack’s ass grew to overshadow theirs. Applejack grew to be at least twice as large as Twilight. A horn and a pair of wings appeared on her body, making her another alicorn as well.

“Whoa, nelly. Ah got even bigger.”

“How is that possible?!” said Twilight.

You placed a hand on Applejack’s ass, marveling at its size and thickness. Despite her now bigger size, her ass still maintained its perfectly smooth and round shape.

Your hand sank into her soft, malleable flesh. You dug deep into the thick layers of squishy soft fat before meeting the strong, muscles far underneath.

“Ya like them big apples, don’t ya? Ah wonder if ya can make me even bigger if ya cum inside me again?” said Applejack.

“Hey! I want a turn!” shouted Pinkie Pie.

“Sure Pinkie, ya can use mah new big fat ass as a couch.”

With that, Applejack lay down on the floor before you. You laid yourself down on Applejack’s right cheek. Her ass felt like a warm, waterbed as you sank into the thick layers of squishy soft fat, before you met her powerful muscles deep beneath.

At the sight of a pinkish blur of speed, you suddenly found Pinkie Pie on top of your cock in a reverse cowgirl position, which gave you a nice view of her ass. Rarity lay herself down next to you on the right. While Fluttershy joined you on the left. Applejack’s ass was so large there was more than enough room, each cheek of her ass was like a couch in itself.

Pinkie slowly lowered her ass down onto your cock, taking you in, inch by inch, giggling in joy while she did so. Rarity and Fluttershy licked and kissed your cock just under Pinkie’s pussy, the two moving their heads down as Pinkie took more and more of your shaft inside her. Alas, your cock made less than halfway before hit her deepest barrier.

“Aww!” said Pinkie sadly. “Anony needs to powerup my body with his wonderful magical human cum of friendship.”

“Of course Pinkie Pie. I love to see how big your ass gets.” you said, giving her right cheek a playful slap. This resulted in her cheek slapping against the other one with a delightful sound of flesh slapping against flesh.

“Woo! Get ready to cum Anony!” she shouted.

Pinkie without magical aid was able to move up and down your long cock in quick strides. She giggled happily while doing so. The mare stared back at you with a big cheesy smile. Combined with the sight of Pinkie Pie being so happy and the fact Fluttershy and Rarity were licking and kissing your cock you were near the point of release already. Not that it mattered, since you seemed to be able to cum and cum without stop while still remaining hard.

With that, you came… already. Pinkie’s cutie marks glowed with magic and she started to grow in size. Fluttershy and Rarity jumped down off Applejack’s ass.

You watched as Pinkie's expanding rump swallowed up your cock. A dark shadow started to creep over you as her rump rose higher and higher into the air.

An avalanche of massive pony ass then collapsed upon you with a wet, meaty smack, taking you into a wonderful world of darkness and candy smelling ass. The sudden slam of massive ass upon you should have broken your bones, but it seemed pony love magic protected you.

“Aww, I didn’t grow so big. I’m only as big as Twilight.” Pinkie whined sadly. “Hey, you wanna test if I grow even bigger with another round?"

You heard all the others hum in agreement.

With that Pinkie lifted her ass high into the air, before slamming back down upon you with an earth-shattering kaboom. Applejack hissed in pain and her ass wobbled about like a stormy ocean from the impact. You grunted a little in pain. But the pain was not so bad, it was vastly overshadowed by the softness of Pinkie’s ass.

Pinkie Pie lifted her ass again and did the same, again and again, slamming down upon you with greater force and speed each time, giggling all the while she did so.

Loud slapping sounds filled the room as she relentlessly bounced atop you, her ass soon became a blur of motion of speed. She moaned and made quiet horsey sounds in bliss. You, in turn, uttered muffled moans into her ass each time she slammed her ass down on your body.

Your cock twitched inside her and you soon found yourself releasing again. Your seed shot into her, filling up her thick and meaty marehood with your love cream.

Pinkie Pie dropped her huge ass down on you for one last time with a hard, meaty slap. From there, she began to grind her soft, fat ass back and forth over your body as her cutie marks glowed with blinding light and she once again started to grow in size.

“Muwhahaha! I grow even bigger!” she laughed maniacally.

Pinkie’s ass air-ballooned outward in size over you, increasing the weight and pressure upon you. You were somehow able to see Pinkie Pie growing in size over you by a third-person perspective.

Pinkie’s ass grew to overshadow Applejack’s ass below her, her ass soon advancing beyond onto her lower back. Bookshelves soon fell over as Pinkie’s bloating cheeks pushed into them. The sight of falling bookshelves caused Twilight to gasp in shock. Pinkie’s head rose toward the ceiling. Just when she was about to touch it, she stopped growing. However, she needed to duck her head a little to avoid poking her new alicorn horn against it.

You were now trapped between two huge pony asses. Pinkie Pie was now easily about twice as large as before. She was in fact so tall, she could not even stand up in the library.

“Let’s help Anon get out.” said Applejack.

“Okay, but let’s have fun doing it.” said Pinkie.

Pinkie Pie and Applejack grinded their massive asses back and forth against each other, this made a loud, meaty slapping sound of flesh slapping against flesh. Applejack hissed in pain from the great weight of Pinkie’s ass upon her. Pinkie Pie, on the other hand, was giggling while she dominated the smaller mare beneath her.

You found yourself sliding down the soft hill of Applejack’s ass. You soon came to fall off her ass, but you landed safely on Celestia's smaller ass sitting down below, which broke your fall from the hard wooden floor.

You stood up and walked back over to the couch. Rainbow joined you on the right, Rarity joined you on the left, and Fluttershy sat down at your feet. All three mares stared hungrily at your erection.

“Let’s test what happens if he cums inside a pony’s mouth.” said Rainbow Dash.

Rainbow and Rarity kissed both sides of your thick cock at your midsection. Fluttershy below took your left ball in her mouth and began to lovingly suck on it. The other mares in the room simply watched to see what would happen. Except for Applejack and Pinkie, who were grinding each other’s massive asses against one another, moaning aloud while they did so.

Rainbow lifted her head over your member. She took a deep breath before plunging as much of your cock as she could down her throat. She made a powerful swallowing motion as she sucked on your dick.

At the prospect of seeing these mares grow big as well, you soon found yourself near the point of release. So, with that, you soon came into Rainbow’s mouth. Rainbow pulled her head back and turned to look back at her cutie marks to see them glowing with blinding light. But she did not start to grow in size.

Your cock blasted a huge blob of your seed all over the mares around you while Rarity moved to take your tip into her muzzle. Once her muzzle was over your tip you gave her a blast of your seed. Rarity pulled her head up from your member and looked back to see her ass glowing with blinding light as well. She too did not grow in size as of yet.

Fluttershy quickly flew up and took your member into her mouth. She was too greeted by a blast of your seed. She pulled her head up to look back at her ass to see her cutie marks were glowing.

All three mares then shot upward in growth. Rainbow and Rarity grew to be about the same size of Celestia. Fluttershy, on the other hand, was growing… MUCH BIGGER.

Fluttershy moaned as the growth flowed through her. Her cheeks came crashing down on everypony like a tidal wave, smothering everyone in the room under her ass. Her head soon blasted through the ceiling and her flanks bulldozed down the walls.

Fluttershy continued to grow and grow, her body surging up over the surrounding buildings of Ponyville, her gigantic rump rapidly spreading across the street.

Her butt continued to grow larger and larger, quickly reaching the nearby thatched houses. When her inflating flanks reached them, the squishy soft fat of her cheeks got pushed back, depressing deeply against them.

Fortunately, before things could get too out of hand, Fluttershy’s growth ceased, stopping just short of bulldozing the surrounding houses. A vast dark shadow loomed over the sleepy little town. Fluttershy had grown so large, she was about twice the height of the very building she used to be in.

“Oh my… I hope everypony is Okay.” she said, flashing her horn with golden light, magically scanning the others trapped under her ass. She sighed in relief, seeing that they didn’t seem to be crushed into oblivion and could still somehow breathe.

“Let’s turn everything back to normal.” she said, flashing her horn, while she clapped her two hooves together.

With a flash Fluttershy, yourself and everyone were back on the couch inside the fully repaired library. And everyone was returned to normal size. However, they were all still alicorns.

Rainbow Dash sat on your right shoulder, with Twilight below her with her head on your chest, followed by Rarity, resting her head on your lap. On your left, Pinkie lay her head on your shoulder, and below her was Applejack, who laid her head on your chest. At your feet sat Fluttershy and Celestia, Fluttershy on the right, Celestia on the left.

Everyone, including yourself, was glaring angrily at Fluttershy.

“Not cool! I liked being big! For once in my life I had a big thick ass.” said Rainbow.

“You big meanie! I want to be big again! You ruined my big fat bouncy castle ass!” said Pinkie.

“I was enjoying seeing my rump being so huge.” said Twilight.

“Indeed. I was looking so thick and fabulous in the rump as well!” said Rarity.

“Yeah! Ah too loved seein’ mah booty being so huge.” said Applejack.

Celestia simply said nothing but had a smug grin on her face. She looked back at her own ass seeing that it was now the biggest ass of the seven mares in the room.

“Please everypony. Calm down. You can grow bigger with magic. Don’t you feel how magically strong you are now?” said Fluttershy in a soft voice.

“I…. you’re right. I feel…. So… much stronger now.” said Twilight, the others nodded in agreement.

Twilight flashed her horn and started to slowly inch upward in size. The rest soon joined in, flashing their horns and slowly growing in size as well.

There became less and less room on the couch, and you soon found yourself smothered under growing pony asses. You magically were allowed to see that the dimensions of the room started to push away from them as they grew in size. At the same time, the exterior of the building didn’t move.

“See everypony? We can keep growing bigger and bigger now. And we can shrink back down to normal if need be later.” said Fluttershy.

“Awesome. Let’s get Anon to cum inside us again to make us even more OP!” said Pinkie Pie.

“But this time, let’s get him to cum inside us while inside us.” said Rainbow Dash.

“Sure thing, my sexy overpowered ponies!” you said. Your voice was carried in the air by magic. Since your real voice was muffled by big fat, giant pony ass. Fluttershy's ass to be exact.
