A Human And A Rainbow Pony
On a bright sunny day in magic horse land there was a human, who was dressed in a fine black tuxedo and fancy black shoes. That human was you, who looked rather depressed as you sat down on a wooden stump in the middle of some sort of medieval like town, populated by small alien horses.
The town was far cleaner than the average medieval town from what you’ve seen on TV at least. These thatched houses you saw had many modern appliances like toilets, electricity and running water. The strange alien ponies stood only at about four foot tall, had very big heads and insane basketball sized eyes.
You sighed in sadness. "Nopony will have sex with me," you said in a low voice.
Oh woe was you. You were in the magical land of Equestria and none of the ponies had a human fetish. Sure, they treated you rather nice, gave you a free house, free top of the range medical care and decent welfare to live on.
But no sex just boring ass magic of friendship. You just had to be teleported at random into a universe of Equestria where none of the ponies wanted the Human D.
… or so you thought.
"Anon?" whispered a soft voice from behind you.
Slowly, you turned around to face the one and only Rainbow Dash. A beautiful, light blue coated pegasus with a fine toned ass and a rainbow mane. However, her butt was a lot more plump this week, since she challenged Princess Celestia to a ‘magic butt fattening cake eating contest’.
Naturally Rainbow Dash lost, but her butt expanded a great deal nonetheless and was even quite a bit bigger than Pinkie Pie’s big fat rump.
Your heart skipped a beat. Could this be the moment you were waiting for? Have the Clopper Gods answered your prayers of cumming inside Rainbow Dash?
"Human, I would like you to cum inside me with your homo sapien cum inside me," she said sexfully in a hot breathy voice, looking at you with bedroom eyes.
"I want to cum inside Rainbow Dash," you said quietly, looking at her with seductive eyes.
Rainbow Dash squealed in joy, making a sound like a squeaking ball.
The winged pony lunged forward to take hold of you with her powerful hooves, said hooves were softer than velour, that a certain space captain would be proud of.
Once you were held in her grasp she blasted off into the sky at such great speed she was little more than a rainbowish blur. She payed no heed to your screams of terror whilst a content smile was upon her face.
Seconds later, Rainbow Dash gently put you down upon the ground.
At first everything was blurry, you could not make out a thing. However, your vision soon returned and you found yourself butt naked, in what appeared to be in an oak wooden walled room.
You lay upon a small, single bed, with a light blue blanket, decorated with several stars and half moons. Along the walls there was several of neatly stacked bookshelves.
Rainbow Dash stood at the foot of the bed, swishing her rainbow tail from side to side along with her fat rump raised into the air. Her bubble butt was quite a sight to behold. Those plump, perfectly smooth, rounded, shapely cheeks metaphorically begged to be rubbed and humped all over.
You became hard like a diamond down stairs. Your cock rose high to attention to her gigantic fat ass. Pony buttmagic giving you a mighty long and thick horse like cock to give that butt of her’s the hard pounding it deserves.
You were lost to the world as you stared at her beautiful butt. Her marehood glisten in anticipation of you cumming inside her.
"What are you waiting for Anon? Cum inside me already," she said sensually, looking back at you with bedroom eyes.
Suddenly, you noticed that there was a nearby telescope sticking out a window next to your bed.
You sat up with a start. "Wait! This is Twilight's room?!" you shouted in panic, eyes shifting from left to right nervously.
Rainbow Dash snorted, rolling her eyes with a nonchalant wave of her hoof. "Was Twilight's room more like. She got a big ass fancy castle now."
"Oh, but I thought it got destroyed by--
"Shut up and cum inside me you big sexy ape!” she shouted, scraping her hooves upon the ground.
"Cum at me Rainbow Dash," you said sexfully, followed shortly by flashing her an insane happy grin.
With that Rainbow Dash flapped her wings and took off into the air.
The mare slowly flew toward you. Once there, she gently pushed you over onto your back, before proceeding to straddle her hind legs tightly around you.
You hissed in pain when her massive rump came to rest upon your lap. Rainbow was a great deal more heavy than the last time she sat on your lap. That was just friends lap sitting though, this was something else entirely.
All that cake fat had to go somewhere, thankfully most of it appeared to have gone to her rump, thus she kept her overall athletic body, while at the same time she gained a massive, bootylicious butt. Slightly disproportionate to the rest of her body, but not overly so.
Her heavy, plump blue buns rested hard upon your pelvis, pinning you down to the bed from under their immense weight.
So heavy she was, you found it a little hard to breathe from under her. You were at her mercy, that humongous fat ass of her’s could possibly be used to break your bones if you upset her. Your towering cock stood between the thick, wide expanse of her fat buttcheeks. Your long, fat cock gently brushed against her tail and plump donut asshole.
"Jeez! Rainbow Dash, you got heavy," you said in a low raspy voice.
Her jaw dropped and ears drooped sadly over what you just said.
"I know. I shouldn't have eaten so much cake! I am a big, ugly fatass pony now," she spoke in a low voice, looking down sadly, tears in her eyes.
You could not stand to see this poor, beautiful mare get upset. Thus, you lifted your hands up to place them upon her cutie marks on both sides of her huge fat flanks.
Once your hands lay upon her rump, you had pressed your fingers into the soft fat of her glorious mounds of fat pony booty, the pillowy soft flesh easily depressing under your hands applied pressure. With loving affection, you tenderly squeezed that big blue bubble butt of her’s.
Rainbow cooed, loving the feel of your tender hands upon her big blue pony butt. Your hands sank deep into the thick layer of fat from her massive flanks. The oh-so soft fat of her rump felt amazing, softer than silk. So warm and cuddly soft it was, the butt fattening cake made her lose all that rough muscle.
However, as your hands pushed down the fat lower, you eventually came into contact with the firm, strong muscles deep blow the thick layer of soft fat powered by cakes. These muscles represented the time before she ate the butt fattening cake.
The pegasus moaned, her wings spreading wide over the loving attention you are giving her butt.
No words were needed as you showed your love for her butt. Your hands roamed across the wide expanse of her massive rump, rubbing the tender flesh gently and giving a tight squeeze here and there.
Each time you squeezed her ass, Dashie uttered low lustful moans. You tenderly massaged that glorious, massive fat rump of her’s, caressing and rubbing away any pent-up stress that her firm muscles had, which lay deep beneath the thick layer of soft fat given to her by those cakes.
The mare uttered a low sad, whine when she felt your hands abruptly lift off her rump. As if by magic, the moment your hands lifted off her rump, her cheeks within mere seconds were restored to their perfectly smooth shape.
"Hey, what are-- Neighhhh!" she shouted animalistically.
Both your hands simultaneously came hard down upon her ass, slapping that lovely butt, as a result her massive cheeks wobbled from side to side.
"Oh Anon! Stick it in me now!" she shouted excitedly, clapping her hooves together in joy.
So, with that the mare adjusted herself over you, her thighs brushing lightly against your stiff cock, at the same time you used your hand to guide your cock into her cum receiver, aka her glorious magical pony pussy.
Her marehood was soaking wet over the prospect of you cumming inside her. You were going to cum inside that pony.
"Oh Anon, I never had anypon-- any human cum inside me," she said in a low voice with a bright red blush upon face, embarrassed over being a virgin.
"That’s my Rainbow Dash. Only homo sapiens can cum inside Rainbow Dash!", you said sexfully, before giving her fat butt a hard slap.
Rainbow Dash moaned, her massive butt jiggling from the hard impact of your hand.
A smug look came upon her face. "That’s right. It’s heresy for a pony to cum inside me, Rainbow Dash. Only humans can cum inside me, Rainbow Dash!" she proclaimed proudly.
Rainbow Dash bit her bottom lip, before taking the plunge. There wasn’t much of a reaction from her at first when your tip entered inside, that soon changed as you began to penetrate her deeper.
Her eyes rolled back in their sockets along with her tongue lolling out from her mouth, moaning in pure ecstasy as your cock went deeper and deeper inside her wanton depths. Inch by inch, she took it all in. The union between homo sapien and interdimensional alien small horse was wonderful.
Surprisingly, Rainbow Dash took your long and thick cock with stride, not complaining in pain or anything despite this being her first time. Her marehood must of been specifically designed for a human to cum inside by some sort of divine being.
Rainbow sighed happily when your thick cock came to rest within her deepest barrier.
You looked at one another with love in both your eyes. Overwhelmed by how cute and sexy she looks, you had thus had lifted your hand to stroke her rainbow mane. Her hair was soft like silk, the mare smiled joyfully, loving the feel of your hand petting her mane.
Without a word, Rainbow leaned forward to press her lips against yours. She growled in frustration when she pushed her long, thick tongue against your tight bared teeth, you not allowing entrance inside.
You laughed, before opening your mouth and letting her inside. Both your tongues came together to dance, swirling around one another. Her tongue was a lot stronger than yours, but despite her tomboyish nature the mare gently stroked your smaller human tongue.
Rainbow Dash giggled, gently brushing her tongue against your front, sharp canine teeth, loving the foreign feeling of your predatory teeth.
You uttered a low, lustful groan when Rainbow began to bounce that glorious fat bubble butt on top of you. Immediately, your hands rejoined her plump flanks, digging deeply into the thick layer of her amazing soft fat.
Her massive blue booty slapped hard against your flesh, at the same time you humped upward to meet her in time with her bounces.
Rainbow Dash’s bounces slowly became harder and harder as Dashie got more and more excited. You felt no pain, just the tightness of her slick vagina milking you for all you were worth and that soft, heavy booty slamming up and down upon you. Despite the immense weight of her massive rump repeatedly bouncing up and down upon you.
‘Hmm. Must of been pony buttmagic,’ came your thoughts.
The room was filled with the slapping of flesh against flesh, along with the moans and groans of both human and pony. Rainbow Dash on occasion making very horsy sounds.
She bounced on top of you, you humped upward. It was great team work.
Alas, all good things must cum to an end.
With that your shaft blasted her insides with thick waves of cum, the mare moaned loudly in your mouth in pure bliss as you did so. Her powerful marehood repeatedly sent thick waves of rainbow colored cum out of her pussy.
Your white human cum and Rainbow Dash’s rainbow cum came to mix together as the combined cum flowed out from her pussy like a waterfall, soaking the bed in the cum of both human and pony.
Suddenly, there was a blinding flash of light and a blue long horn appeared on her head along with her body and butt growing to be about the same size of Princess Celestia’s body.
"Awww yeah, thanks Anon! Thanks to the power of human cum I have become an immortal alicorn!" she shouted, hooves raised in joy. "And a one cool of that, not like egghead Twilight."
"You’re welcome, Dashie."
Rainbow Dash leaned down to give you a light peck on the cheek.
"You gonna be real busy for awhile. After all, your cum turns ponies into alicorns. The more overpowered alicorns we can get, the better. So, you gotta help ponykind by cumming inside as many ponies as you can, so we can protect Equestria from future evil forces."
"I don’t have to cum inside stallion’s butts do I?" you asked nervously, scratching the back of your neck.
"No, you don’t have to. But quite a lot of stallions will be pissed off that they can never be alicorns."
"I can live with that. Besides, they will all probably be red and black."
"Oh, cum here you sexy racist!" she shouted sexfully.
And then you came inside Rainbow Dash again and again forever and ever. Rainbow Dash used her amazing alicorn powers to keep you young and immortal to cum inside her forever.
The End
Princess Celestia pressed her massive fat white butt against a mirror upon a white marble wall in her castle.
"Mirror, mirror, on the wall, who has the most beautiful butt of them all?"
"That would be Rainbow Dash’s butt," spoke the mirror in a deep, manly voice.
"HERESY!!!!!", she boomed.
With that Celestia roared in rage, kicking the mirror with her back legs, thus shattering it into tiny pieces.
