Late at night, you a human lay in bed masturbating with your eyes closed. The white blanket over you was themed with a spiraling sun. That sun was the cutie mark of the alabaster alicorn known as Princess Celestia, a pony sun goddess with a most fine sexy butt.
Her plump, fat ass was so massive and beautiful you thought there was no finer butt in all of existence. All the other pony butts were nothing when compared to Princess Celestia's vastly superior, bootylicious, royal fat pony butt.
Anyway, the walls of your bedroom had many posters of Princess Celestia getting fucked up the butt by handsome humans.
As you lay there jerking off yourself, the mental image of Princess Celestia’s tremendous butt standing before you entered your imagination.
In your mind Celestia pressed her enormous, white bubble butt against you as she looked back at you with a come hither look.
"Mount me, you handsome bastard!" she roared.
With that you placed your hands on either side of her humongous cheeks, before you tightly squeezed them. You watched with a nasty grin on your face as your hands sank deep into the silky soft flesh of Celestia’s flanks, depressing under your applied pressure.
Celestia purred as you roamed your hands all over her massive butt. "Yes! Praise the sun!" she cooed.
With that you pulled your right hand back, before you slapped her cutie mark hard, which caused the massive cheeks of her butt to wobble from side to side.
"Give me the D!" she demanded in a loud voice.
With no further ado, you aligned your cock with her butthole… but when you were about to mount her, something totally unexpected happened.
"Stop it, human!" roared Princess Celestia's angry voice.
You opened your eyes to see the towering form of Princess Celestia looking down at you with narrowed angry eyes as she stood next to your bed.
You masturbated all the harder from the sight of her, which only seemed to make the alicorn even angrier. If her now glowing red eyes was anything to go by.
"Stop masturbating to me you filthy human!" she roared as she slammed her hooves on your bed.
"No! I will not stop masturbating to you!" you shouted in defiance as you continued to masturbate in front of her.
The furious alicorn growled as she bared her teeth while she looked at you with her eyes narrowed angrily.
"STOP MASTURBATING TO ME OR I'LL KILL YOU! YOU DIRTY PEASANT!" she roared in the royal canterlot voice as she fixed you with a death glare.
With lightning speed you moved your hand away from your crotch.
"OK OK!" you said in a panic filled voice.
A long awkward silence filled the room as she continued to stare angrily down upon you. Sweat poured down your face from under the mad alicorn’s glare.
"So… you’re really Princess Celestia?" you said in a nervous voice in an attempt to make conversation.
"YES PUNY MORTAL HUMAN! IT IS I PRINCESS CELESTIA !" she declared in a loud booming voice as her horn and eyes flashed with blinding light, along with her wings outstretched.
"Wh--what are you doing here?" you asked in a nervous tone.
"I'm here to stop you from masturbating to me," she said in a sour voice as she pointed a hoof to a poster of a self insert of yourself cumming inside her butt.
"Why? I'm not hurting anyone," you said in a low, nervous tone.
"I'm sick of hearing humanity crying out my name as they masturbate to me. So, please just stop," she shouted angrily.
"How can you--
"I can hear your voices from my universe next door to yours," she said as she stomped her hoof.
"Right, but I'm not the leader of humanity," you said as you rolled your eyes.
"That is why I'm going to stop all you ugly humans from masturbating to me," she said as an evil grin formed on her face.
You gasped in horror.
"You can't do that!' you shouted in shock.
'Yes, I can. For I am an immortal all powerful pony goddess, while you are a mere stupid, weak human, " she said mockingly.
"Please, a bigger and stronger Celestia with a human fetish come to my aid," you cried out with your arms in the air.
"Hah! Do you really think-- suddenly there was a blinding flash of light, followed by the appearance of another Celestia, who stood twice the size of the other one, on the opposite side of your bed.
"Uhhh…. you’re freakin huge!" she said as she stared wide eyed at the even bigger alicorn in disbelief.
The giant alicorn mare payed no attention to her as she stared down at you with a big red blush on her cheeks as if you were the cutest thing ever.
"Awwww, you’re so cute my little human!" she said as she leaned her head over your bed to look down at you with her eyes sparkling in joy.
The smaller Celestia stared in disbelief at what was happening in front of her.
"You’re the most beautiful lady I ever saw," you said as a happy smile formed on your face.
"Oh, you’re such a gentleman. May I offer you a blowjob my handsome human?" the bigger Celestia said softly as she looked down at you with her eyes filled with warmth and kindness.
The smaller Celestia jaw dropped in disbelief at what was happening
"Uh… I um--- you said in a low, nervous voice. Just before the gentle giant tenderly placed a huge hoof on your exposed chest.
"Awww, don’t be nervous my little human. Over the past sixty five trillion years that I have lived I had sucked quadrillions of human penises from across the multiverse," she said softly as she gently rubbed your chest with her thick hoof. "So, do you want me to suck your cock?"
"Yes please… I would like my dick sucked," you answered in a low voice.
The larger Celestia smiled warmly as she gently placed a hoof on your crotch. However, just when she was about to pull down your underpants the other Celestia slapped her hoof away.
"Stop it!" the smaller Celestia roared as she bared her teeth.
"You’re just jealous because my butt is bigger than yours" she said with a nasty grin as she turned around to rudely moon her with her twice as big butt.
"How could you want to have sex with a human? Their penises are so small," she shouted with her hooves raised high in the air in exasperation.
"Not true. For I have sucked and fucked many a human with a gigantic penis from across the multiverse! Also genetic engineering and a bit of penis growing magic can fix little issues like that," she said as she looked at you with bedroom eyes.
"And besides, human hands are amazing!" she added with a bright red blush on her cheeks.
"Ewwwww! You are disgusting!" she roared as she raised her hooves in the air.
"Well, whenever you change your mind about human on pony action. You are more than welcome to join us," she said with an evil grin.
"Ewww! How can you find humans sexy? They are ugly hairless apes!" she asked with wide eyes in shock.
"Oh, I don’t know. Maybe because the heart attack cute expressions they make as they stare at you with their adorable little eyes when they hold your butt with their hands as you make love with them. The amazing feeling of their skin against my fur. The appearance of their penis I find is far nicer than a stallion’s. The delicious taste of their cum. Oh, how I love the feel of their hands. I just love how their hands stroke my mane, rub my belly, hold my butt and finger bang my pussy. And their women’s boobies! Oh, how I love to bury myself between them and suck their nipples!" she said with dreamy eyes.
"By Faust! You’re a pervert!" she said as she held back the bile down her throat.
"And you are a boring prude," she said mockingly, before she cheekily stuck out her tongue. "Now, if you excuse me I got a human dick to suck."
With that the bigger Celestia flashed her horn, before pulling down your boxers. The mare leaned her head down, slowly closing her eyes as she quickly closed the distance between her muzzle and your cock, which twitched excitedly as her lips closed in on it.
However, just when her lips were about to touch it, the other non human fetish Celestia pushed her head away.
"Hey!" the bigger Celestia shouted angrily.
"Fucking cock blocker!" you shouted angrily as you slammed your arms upon your bed in frustration.
"Stop it! Stop it now!" she roared as she flashed her horn with deadly magic. "I command you to-- OW!” she cried out in pain as the bigger Celestia slapped her across the face with her huge hoof.
The larger Celestia hit her with such strength it caused Celestia to fall over onto her backside and stop her spell dead in its tracks
"How dare you threaten me and stop me from giving such a nice human a blowjob?!" she roared as she glared daggers down at her.
"How dare you slap me?!" she shouted as she jumped to her hooves.
"I will kill you and your hu-- Ahhhaaahhhaaa!" she roared just before the bigger Celestia in one quick motion like a kung fu master had leaped high into the air over your bed, in order to kick her in the chest with her two thick and powerful back hind legs.
The force in which she hit the smaller Celestia sent her flying through your window, into the sky, and hurtling far out to space.
"Nobody hurts my sexy humans," she said angrily as she flashed her horn to magically repair your window.
A warm smile came on her face as she turned back to face you. "Now, where were we," she said with a lustful tone as she looked at you with bedroom eyes.
The warm smile soon faded away when she saw the fearful look in your eyes. "Oh human, I would never do that to you," she said softly as she approached your bed.
When you said nothing in response she proceeded to stand up on your bed, casting a dark shadow over you. The newly added massive weight of her body had caused the wooden supports of your bed to creak loudly.
You gulped nervously as you stared up at the massive, towering mare who stood above you.
"Please, be gentle," you said in a low voice as you looked at her with pleading eyes.
"Oh, I will," she said as an evil grin formed on her face.
Ever so gently the huge, towering mare slowly descended over you, straddling herself on top of you. You were barely able to breathe and it felt quite painful from being under her immense weight, topped off with her massive rump lying on top of your crotch. The heavy weight of her body pressed you deep into the mattress below.
The enormous amazonian like mare giggled happily as you became a shivering wreck from under her. Your pelvis felt rather painful from being under the intense weight of her gigantic butt sitting atop it.
"Please… don’t crush me," you spoke in a low, raspy voice.
"Oh, don’t worry my little human. My butt won't crush you.... much," she said as she looked down at you with a nasty grin.
You opened your mouth in reply, but only a groan escaped it as the massive mare’s body oh so gently began rubbing against you. The feeling of her fur felt silky soft against you, along with her massive butt gently squeezing your cock between her titanic mounds of her luscious buttcheeks.
All this had left you once again as a shivering wreck.
Your small human cock below the towering form of her enormous butt, had barely even reached her marehood as the soft, thick flesh of her butt gently cradled your penis in a tender show of affection.
"Don’t fear the giant sun, my little human. The sun only wants your love," she said softly as her huge magenta eyes stared into your own with utmost kindness behind them.
A moment later, Celestia’s horn became surrounded in a golden aura, then you felt a tingling sensation flow through your entire body. Whatever spell she cast, you seemed to no longer feel any pain and could breathe easily once again.
"Thanks Celestia," you said softly as you rubbed a hand through her mane.
"You’re welcome," she said, before she looked down at you with pleading doggy eyes. "Now my handsome human, can you please take hold of my butt?" she said in an imploring tone.
Not wanting to disappoint her you swiftly placed your hands on each side of her massive butt, the soft flesh of her rump conceded back to your touch. The mare above you smiled broadly as you held her butt with your hands.
However, the smile soon faded, when you merely held your hands on her smooth buttcheeks and did nothing else.
"Go on my little human, praise the sun," she said as she looked at you with a slightly annoyed look.
You squeezed her huge butt, digging deeply into the soft flesh of her thick rump. Fearful of making her angry you proceeded to roam your hands all over her butt, giving her a tight squeeze here and there.
The massive mare atop you moaned as you fondled her butt all over. She in turn tightly pressed her massive bubbly buttcheeks together, smothering your cock in a thick layer of silky soft butt fat. Then without a word, she had tilted her head a little to the side, before she leaned her long swan like neck forward, slowly closing her eyes as she pressed her lips into yours.
The mare moaned as her soft, plump lips pressed against your own as she drove her massive tongue deep into your mouth, all the while her immense butt continued to gently hug your cock between her enormous cheeks.
The long and thick alicorn tongue danced with your far smaller human tongue. Both of your tongues swirled around one another as they gently caressed each other as both human and pony moaned in bliss.
A giggle escaped her throat as her tongue played with your sharp canines, loving the errotic feel as her tongue lightly brushed over them.
Human and pony continued to kiss passionately with their bodies tightly pressed against one another. Her massive butt still continued to gently embraced your cock.
Nothing could ruin this tender moment between a mortal human and an immortal alicorn.…
"STOP THIS AT ONCE!" roared the smaller Celestia from before as she smashed through your window to land at the foot of your bed.
Two painful looking bruises in the shape of hoof marks were across her chest. The bigger Celestia lying atop you turned around to give a death glare to the other Celestia.
"You dare come between me and my handsome human?" she said quietly with her eyes narrowed in rage, said eyes glowing bright orange.
"What you are doing is an abomination! Humans and ponies can’t love one another!" she shouted.
"Oh, go back to whatever boring non human fetish universe you came from!" the Celestia atop you roared as her horn flashed with blinding light.
"You die now--” she roared with her horn flashing…. but only harmless sparks flew out of her horn. "What the?! What have you done?!" she shouted with wide eyes in shock.
"Oh don’t worry, your magic will come back. When you stop being an anti human and pony sex cunt!" she said mockingly as a nasty grin came upon her face
"What?! You can’t---
"Begone! You have delayed my human on pony buttsex for long enough!" she shouted angrily with her horn flashing with blinding light.
There was a flash and the non human fetish Celestia was gone. The Celestia atop you flashed her horn to once again fix your window, before she turned to look back at you with bedroom eyes.
"Let’s ready up that cock shall we?" she said sexfully.
The alicorn shifted herself over you, resting her head just above your crotch. Then, without a word the mare took the tip of your cock into her muzzle, before in one quick scoop she took your entire cock and balls into her spacious mouth, your cock barely reaching her throat.
Celestia gently suckled on your cock in her mouth, swirling her tongue all over it. You groaned in pure ecstasy as your legs spasmed uncontrollably as if they were receiving an electric shock. Her lips curled into a nasty grin, just before she began to bob her head up and down your shaft.
You cried out as you sat up to wrap your hands around her head, gripping her mane tightly.
"Ahhh fuck, I won’t last ten seconds if you keep this up!" you shouted.
The mare ignored you as she mercilessly bobbed up and down your shaft. You held out as long as you could, but it was not long till your grip on her mane became loose as you fell onto your back, whilst you thrust erratically into her mouth as your semen fired into her.
The mare hummed happily as you shot a few last strands of your spunk into her, before you became limp like a fish out of water with your whole body shaking.
"Oh…. I’m sorry. I didn’t last long," you said in a low voice.
Celestia swallowed, before she lifted her head. "Hey, don’t feel bad. If it’s any consolation, you lasted far longer than the human I sucked off yesterday. For he came within two seconds once I started," she said softly.
"I guess that makes me feel better," you said in a low, sad voice.
"At any rate, time for human on pony buttsex!" she shouted excitedly as she clapped her hooves together in joy.
Celestia smiled nastily as she flashed her horn, a moment later you felt a strong tingling sensation as your cock began to rapidly re-harden… and grow to a ridiculous size.
"Yeah, I think I feel better now," you said as you stared with wide eyes at your new insanely long and thick cock.
The mare shifted herself over you, positioning the thick tip of your cock before the entrance of her butt hole. Just when she was about to push her butt down on your cock, you stared pleadingly into her eyes.
"Wait… I want your magical pony pussy," you said quietly as you stared into her beautiful, huge eyes.
"OH HUMAN! she cried in happiness.
The mare magically guided your cock to the wet entrance of her marehood, before she slowly took in the thick tip of your cock inside.
You groaned as you placed your hands on her rump to tightly squeeze her bountiful cheeks, compressing the soft fat of her butt as she slowly but surely took in your massive cock inch by inch into her. Both human and pony moaned lustfully as they joined one another in tender human on pony pussysex.
Once you finally bottomed out deep inside her love tunnel the mare had leaned forward to press her lips into yours.
The huge mare atop you passionately kissed you, both your tongues danced with each other once again as her hot, slick insides tightly hugged your long and thick cock deep inside her vagina. Her dripping marehood making your saliva soaked cock just a little more slick as it stood tall and proud deep inside her.
You groaned in her mouth when she began bouncing her enormous butt on your lap. You in turn thrust your massive cock upwards to meet her bounces. The sounds of flesh slapping against flesh along with moans and groans of both human and pony filled the room.
As the mare continued to bounce atop you, you took the liberty to roam your hands over the soft, bountiful cheeks of her massive butt. You fondled her butt all over, giving a tight squeeze here and there.
However, you began to notice something rather odd happening. You didn’t really notice it as first, but it seemed you had to stretch your arms further and further. At some point your hands slipped ever further away from her butt… until you could no longer hold it.
…. and then you heard the wooden support of your bed snap, thus your bed slammed to the floor with a loud bang. This startled you, causing you to open your eyes to see the already massive mare atop you had grown several times bigger.
You pulled your lips away. "Hey, I want to hold your butt!" you shouted.
"Hey, I made your cock bigger inside me too!" she stared at your unimpressed face, before a moment later she sighed in defeat. "Oh, you’re no fun."
The mare’s size rapidly shrank back down to a level you could just about place your hands on her rump. "There! Happy now?!" she grumbled
You gave her massive butt a tight squeeze, digging deep into the fat of her thick cheeks.
"Yes, much better," you said as you gave her spiraling sun cutie mark a hard slap, which caused her to moan aloud as her enormous cheeks wobbled from side to side.
A second later, your lips rejoined and she resumed bouncing atop you. Your grip on her butt was all the more stronger, your hands tightly squeezing the silky soft flesh of her ass as you groaned into her mouth.
The several times bigger butt now on top of you was quite a deal heavier than it was at first. This was not helped by the fact the massive mare had began slamming herself harder and harder down upon you.
A scary thought entered your mind, if Celestia had not used her magical protection on your body you were quite sure you would have been flattened like a pancake. Judging by the sheer weight and force of her butt that was now slamming down upon you.
You cried out in pure ecstasy as your defences quickly withered away, even with a magically enhanced cock, it was no match before the glory of Celestia’s gigantic butt slamming harder and harder down upon you.
You made one last desperate stand… before you grunted as you exploded into her. Your love cream blasted deep into the hot confines of her pussy, her powerful insides squeezing your cock, milking your cock for everything it was worth.
Wave after wave of cum blasted into the huge alicorn. Soon, the sheer quantity of your cum was so much it came to the point she could no longer contain it. Thus the bed was soaked in human and pony cum that flowed out of her dripping marehood.
Eventually, your blasts of cum became less and less, until you finally stopped. Your cock deep inside her had began to soften.
Celestia slowly parted lips with you. "If you ever want to bang me again. Just shout ‘I need Celestia’s big fat pony booty’ and I’ll come to you," she said as a nasty smirk formed on her face.
With that she disappeared in a blinding flash of light.
"I need Celestia’s big fat pony booty!" you shouted the moment she was gone.
Celestia reappeared atop you. "Miss me already? Well, you better give me buttsex this time," she said before she stuck her tongue out with a silly look on her face.
"Yes, my sexy pony princess," you said sexfully.
Celestia teleported herself to the opposite side of the room. Once there she looked back at you with a come hither look.
"Mount me, you handsome bastard!" she roared.
With a nasty grin on your face you stood up out of the bed, then walked toward her, using your hand to hold your massive magically enhanced cock at the ready to fuck her butt.
The End
Author's Note
No buttsex this time.
I stayed up late on a Friday night writing this.
