A Big Rainbow

It was a most joyous day, the sun shone brightly in the near cloudless sky, birds were singing and there were at least a dozen or so rainbows in the sky today.

Along a paved path there was a wooden bench. A strange being wearing a tuxedo was sat upon the bench, the being was you, a human.

Right next to you, upon a much larger bench was a minty green unicorn. Yes, a unicorn, and a really big one of that. She towered over your small form, you were a mere ant in size when compared to her huge form, for she was about as wide as two... two story houses put right next to each other and twice the height of a two story house.

Thankfully, the unicorn seemed to pay no attention to you whatsoever. You can’t even recall if this pony ever spoke to you, which was strange since quite literally everyone of these big ass horses wanted to talk to you.

In fact, several times you've tried to start a conversation with her in the past few months you have been here, which only resulted in her simply giving you a harsh look before walking away.

Eventually, you did learn your lesson and no longer even tried to talk to her. So, in peace and quiet you read your especially designed newspaper for your size without any of those ponies to interrupt you.

Alas, as if by some cruel fate there soon came a powerful gust of wind out of nowhere, blowing your newspaper far away into yonder sky… and also a massive… vast dark shadow had appeared over you.

Slowly, trembling in fear, you looked up to see a big... a REALLY big blue pony with wings and a long, thick horn atop her head, who was hovering just a few feet above your head. This big blue pony was about as tall as the Empire State building and her body was about as wide as the Michigan Stadium.

Yep, she be a really big pony.

"Hey Anon, wanna hang out?” she said softly, looking down at you with bedroom eyes.

You simply gulped in fear, staring up in terror at the giant blue alicorn looking down at you with lustful eyes and licking her lips as if you were a piece of meat.

The minty green unicorn simply uttered a low growl, before jumping to her hooves to quickly trot away from the area, leaving you alone with the big blue horse giving you lustful looks.

She continued to look sexfully upon you, until you eventually found the courage to speak.

"Uhhhh… Rainbow Dash, why are you looking at me like that?” you asked, nervously scratching the back of your neck.

"Luna tells me you like a big rainbow in your dreams… “ she said mockingly, before speaking sexfully. “My big rainbow. Isn't that right, little man?"

"Goddamn it Luna! I told her not to tell anyone!" you shouted.

"So, how about you ride my big rainbow, little man?"

Sweat poured down your face as you became red as a tomato. "But.... Rainbow you're.. so... so—"

"So big? That only makes it even hotter!" she shouted excitedly, dropping down to slam her heavy, enormous rump hard upon the pavement.

The ground shook violently, the hard impact of her monstrously large, heavy butt left a deep crater in the earth beneath her.

"Whoa! Fuck!” you shouted, nearly falling off your bench. “Be careful you big fat horse!" you yelled, glaring at her harshly.

"How dare you!” she roared angrily, staring down at you with narrowed eyes. "I may be big, but I'm not fat! Take that back, you little, small penised ape!"

“Well… Rainbow, you're fat butt is huge—”

"No, my butt is not fat! Look!" she shouted, turning around to show her massive butt, casting a vast dark shadow over your tiny form. "Look how small and thin it is!”

You gulped in fear at the sight of her massive, skyscraper high, plump rump, standing tall and proud before your tiny form. Rainbow Dash's butt was one of the biggest, strongest, fattest pony butts of all ponykind. Although, she herself thought it was small and thin.

Her fat cheeks was about as wide as a football stadium, if not even wider. Her cheeks were thick with layer after layer of squishy soft fat before reaching the hard, firm muscle deep beneath.

Her massive cheeks were perfectly round to form the shape of a perfect bubble butt. High up above her towering mounds her long, rainbow tail covered her assets. A set of powerful, long, thick hind legs supported the immense weight and size of her mighty alicorn butt.

"See? Look how small and thin it is when compared to Princess Celestia's big fat butt," she spoke, in a nervous tone, before raising her voice in a rather defensive manner. “I don’t spend all day sitting down on my ass stuffing myself with cake.”

"Admittedly, your butt is smaller than Princess Celestia's butt, but your butt is still very fat,” you said firmly.

"Hey, just because I’m an alicorn doesn’t mean I have a fat butt!” she protested.

“I think all alicorns have fat butts, Dashie.”

"We'll agree to differ,” she said in a flat, neutral tone.

A long awkward silence ensued.

"Well, are you going to cum inside me now?” she said in a soft tone.

You crossed your arms and simply said in a quiet voice. “No!”

“Grrrrr!” she growled, stomping her massive hoof, causing the earth to shake violently, knocking over several trees and leaving a large crack in the ground. “Don’t be a heretic Anon, get your small human penis ready and cum inside the big rainbow!" she shouted angrily.

You whimpered like a dog in fear, before dropping to your knees before her. "Okay! Okay!... I'll... I'll cum inside you Rainbow Dash," you said in a low voice, trembling in fear.

She sighed deeply, before speaking in a soft voice that could rival Fluttershy. "Jeez dude, don't be so scared. I wouldn't hurt you, even if you did chicken out and run away like a little bitch.”

“I’ll do it Rainbow, but I have no hope in pleasing you. Since, you’re really… really big,” you said in a low voice.

“I don’t care if you can please me or not. What I value most is the emotional experience of your tiny human penis cumming inside my mighty magical ponypussy,” she spoke in a sweet, soothing voice.

“Hah, now you sound like a bitch,” you said, smiling smugly.

A bright red blush came over her cheeks as she covered her face in shame with her wings. “Yeah well…. you shut up,” she blurted out defensively, not finding any good comeback line.

“But you're still the coolest pony I know!” you shouted, more out of fear than praise.

“Awwww! Give us a kiss, handsome.” she said softly,” dropping her head low, to bring her massive lips right over your body.

You leaned forward to kiss a tiny area upon her lower lip. Dashie’s cheeks flushed red as you left the soft tender kiss upon her.

“That was nice,” she said in a blissful tone. “But now… it’s time to come inside me, to cum inside me while inside me.”

With that she turned around in quick session… to gently drop her massive ass before you, thus only shaking the earth slightly. You gulped, staring up at the massive rump before you, with its mighty size casting a dark shadow over your pitiful form.

You stood before her gate… or rather the plump, pink lips of her marehood, by your perspective the entrance into her vagina had a large, gaping hole, but only because of your small form.

You stood there scratching your arse, unsure what to do for quite some time. Before, you heard a long, drawn sigh from Rainbow Dash. The next thing you knew your body was wrapped in faint, rainbowish light, before your pants vanished with a puff of rainbowish smoke.

“Hey, what the— Aaaaaahhhhh!” you didn’t even get to finish your sentence, when you were sent hurtling into the air into her vagina.

Thankfully, your landing was soft. In fact, it was so soft your body sank deeply into the flesh beneath you.

From being inside her your body soon became drenched in her juices, much of it seeping into your mouth, tasting of skittles. Nonetheless, you were quickly getting a hardon, the floor of her marehood felt softer than silk.

“Hump it with your small penis, ape!” she commanded, in a muffled voice from all around you.

You gave a light lick to the floor. You heard her body rumble, along with a loud moan in response.

“Oh yeah, that feels nice. But hump with your tiny penis human!” she demanded.

“How can you even feel that, you’re huge?” you asked in a curious tone.

“It’s my G-spot. Now quit complaining and get to work!” she shouted.

“Yes ma'am!” you simply said.

With that you began to hump back and forth against the soft floor beneath you, muffled moans and horse noises filled your ears as you made sweet love to her.

“Hah, this actually feels quite nice.”

Building up a rhythm, you began humping her g-spot in earnest, loving the feel of silky soft flesh rubbing off against your cock. Through it all you heard Rainbow making loud moans and horsey noises.

“Mmmmm, neehhhaaa! Keep going!”

From hearing those encouraging words, you humped against the floor of her vagina all the harder.

Hard slaps of flesh against flesh could be heard as you humped the floor in quick, powerful thrusts.

“Oh fuck! I need you to cum first!” she shouted, panic filling her voice.

As if by magical command, you came a mere second later, showering a small area of her vagina with your creamy human spunk.

A moment later, there came a low rumble, before a tidal wave of glowing rainbow marecum slammed into you, sending you hurtling out of her vagina to land in a heap on the ground... and somehow you felt no pain or felt anything break.

“Hey, Rainbow Dash how come I’m not—”

“You seriously didn’t think I was going to put you in there without protection? Come on dude, I’m not that cruel,” she said in a shocked voice.
