Rainbow Wants Inside You

To say you were nervous was an understatement. You were lying next to a ridiculously heavily endowed mare, with a thick, meaty and long cock. Your tiny human cock was nowhere near the size in comparison to it.

You couldn't move, you were simply too terrified.

Fortunately, Rainbow seemed to soon pick up on your anxiety, prompting her to gently rub your back.

“I’ll take the lead. Okay?” she said softly.

With that Rainbow stood up, from there she made to stand over you, her mighty shaft standing tall and proud above you. Its massive size casting a huge dark shadow over you.

Her great big blue fat cock bobbed eagerly in the air, swinging from side to side.

Without further ado, the mare proceeded to straddle herself over you, resting her soft blue bubble butt between your legs, pressing her dripping wet, hot, soft marehood against your manhood.

The only downside was her big, fat, heavy horse-cock came to rest upon your torso, along with her massive balls resting gently upon your far smaller ones.This was made even worse by the fact her cock was so long, the thick and meaty mushroom head of her cock’s tip was pressing against your face. The smell of skittles filled your nostrils as her mighty tip pushed against your face.

You hissed in pain, her balls were heavy. The thick mass of meat resting on your lap was quite uncomfortable to bare.

Rather than protest, you gave her cock a gentle push, moving it aside with your hand, laying to rest her meaty member on your right shoulder. Rainbow sighed sadly when you did that.

“Awww, I wanted to cum on your face dude.” she huffed.

“That would be gay Rainbow. No gay shit is happening here.” you said bitterly.

“Yeah, whatever dude. Stick it in me already.”

You raised your arms, taking a tight grip of her muscular backside. The feel of her soft, furry rump was wonderful, her soft flesh conceding slightly from under your applied pressure, before meeting the firm muscle beneath.

You gently thrust your hips forward, but your penis wasn’t exactly pointing straight, and ended up poking her huge, left testicle, which felt uncomfortably soft and warm to the touch.

Rainbow’s mouth formed a ‘O’ shaped for a brief moment, before shifting into a shit eating grin.

You gave her an awkward smile, before trying your luck again. Your hips lightly thrust forward, this time meeting their mark. The soft, hot and wet walls of her marehood enveloped your tip, causing you to shudder in bliss.

You took a deep breath, before taking the plunge. The soft walls of her marehood, tightly squeezed your cock as you entered her. Rainbow made happy whinny sounds, while you moaned in ecstasy at the wonderful feel of her wet and soft love tunnel massaging your cock within its tender hold.

Soon enough, you were balls deep. Your cock was now lovingly hugged by her amazingly strong, yet soft, wet, and hot feeling walls of her vagina. You had a dream like look on your face, Rainbow on the other hand looked quite disappointed.

You sighed, making to look down at your small, pitiful balls, flanked on both sides by rainbows enormous balls, with its towering slab of fat horse-cock standing tall and proud into the air.

'Man, I’m jealous.’ came your thoughts.

Her cock throbbed powerfully, growing by several more inches. At the same time, her balls grew slightly bigger, causing you to hiss in pain.

Rainbow gave you a wicked grin, before lifting herself up and then slamming hard upon your lap.

Her huge, blue balls came down onto your lap with a loud slapping sound. You uttered a quiet grunt, her heavy balls smacking your legs was a little painful.

Before you had a chance to recover, Rainbow Dash lifted herself up again and came slamming down again.

Repeatedly, without stop Rainbow Dash came slamming down upon your lap, her long, fat cock swung wildly about as she bounced up and down upon you. The sounds of big heavy balls slapping against flesh filled the room, along with your painful grunts of pain from the tremendous weight of her balls impacting your lap.

'Man, this is so gay!’ came your thoughts.

Her cock throbbed powerfully, growing once more in size. However, this time something even worse happened. To your indescribable horror, you felt your shaft rapidly begin to shorten, while at the same time Rainbow's cock grew even larger.

Rainbow uttered a loud moan, her cock going through an overdrive of expansion, soaring into the air, casting a vast shadow over you. Her balls swelled in thickness, inflating like balloons atop you. You hissed in pain at the increasing weight of her growing balls. Your cock was nothing in comparison to her mighty shaft, growing more and more mighty by the second.

You cried out in pain, when her inflating heavy balls came slamming upon your lap. Fortunately, Rainbow Dash showed you mercy, by not bouncing on you again, letting her balls go through its expansion.

You looked on in horror at these turn of events, while Rainbow Dash had a big smug grin.

Shorter and shorter your cock became, filling her less and less, eventually to the point it slipped out of her marehood, continuing to become even shorter from there. Her cock rose into the air, showing no sign of stopping as it swelled in thickness and length by ridiculous proportions. Her cock grew, bigger and bigger, longer and longer, thicker and thicker, fatter and fatter, heavier and heavier.

Your balls deflated, rapidly shrinking into peanut size, and becoming even smaller from there. Rainbow's balls on the other hand began to become mighty big blue beach balls.

In a few short moments, your cock was gone. Replaced with a vagina. Rainbow on the other hand had an even greater cock then before, three times the length and as thick as your own torso.

You raised your hands to cover your face, before you began to wail in grief.

“There-there, Anon. Your penis will grow back if you appease my cock.” she said softly.

“Really?…. No joking?” you said in a low, timid voice.

“Yes. If you worship my mighty magical pony penis, you will get your penis back.”

You gulped, your eyes travelling up the long spire of her massive slab of her fat horse-cock standing tall and proud into the air.

“Gay or not, I can’t live without my penis.”

With that, you licked the monstrously thick midsection of her cock, Rainbow making a loud neigh in approval.

You stood up, you needed to stand up for this… she was huge. You now stood before the high mushroom head that was her cock’s tip. Without further ado, you leaned forward to lick her sensitive tip.

Her cock twitched, hard, rainbow pre-cum the color of a rainbow began to leak from her thick mushroom tip, tasting of sweet skittles.

“Yes! Worship my mighty magical pony penis human if you want your cock back!” she shouted excitedly.

With that you stopped pussy footing around, by wrapping your arms around the ridiculously thick shaft, proceeding from there to stroke her shaft vigorously with both your arms, while at the same time licking her fat mushroom head.

“That’s more like it! Work that cock!”

You hate it to admit it but her cock tasted delicious, the smell of skittles was flowing into your nostrils and the taste of her rainbow pre-cum was quite delicious. You moaned at the taste of her, without stop, you worshiped the mighty pony dong. Rainbow made loud happy whinnies and other horse noises as you worshiped her cock.

“Oh, Anon. I’m about to cum!”

By hearing this you only proceeded to worship her cock even harder. Your head moved about the fat tip of her member, licking every inch of the big blue mushroom before you.

Her cock throbbed powerfully, swelling in thickness and length by several inches, before unleashing a volcano eruption of rainbow cum. Spurt after spurt of her skittle flavored essence showered over you.

By the time she had finished, you were a rainbow colored snowman, covered in hot horse spunk. Nonetheless, you were immensely relieved to feel your cock coming back, growing slightly bigger than it was actually before as if to reward you.

“Okay, that’s over with. I won’t have to do that other gay thing.” Just then, you felt your cock begin to shrink. “Okay, okay! I’ll do it!” you shouted in panic.

Your cock reversed its shrinkage, and returned back to its larger size.

"You cannot escape from the power of horse cock human."

With that Rainbow Dash stood up, her fat cock swinging from side to side, bobbing eagerly.

You gulped reluctantly going on all fours behind her, presenting your ass to the mare. Rainbow wrapped her hooves around your waist, positioning her fat cock's tip at the entrance of your asshole, you shuddered at the feel of her member pressing against it.

“Are you ready for cock you, little faggot?” she said in a nasty tone.

“Yes. Make me yours, Rainbow.”

You cried out in pain when she violently thrusted inside you, her cock went quickly through your intestines, through your stomach, and then up your throat and out of your mouth without somehow killing you.

Tears fell down your cheeks from the pain, your entire body ached from being impaled by her cock. Your body was bloated out, to accommodate the massive shaft inside you.

The big blue shaft's tip out of your mouth bobbed up and down outside of your mouth. But other than that, Rainbow didn't' move, allowing you to adjust to her massive size.

Soon enough the pain began to wither away, replaced with a soothing warmth and a firm hardness deep inside you. You moaned like a bitch in heat at the feel of big fat long pony cock inside you.

Rainbow whinnied softly, before pulling her hips back, bringing her cock’s tip back inside your mouth. A sad sigh left you when you felt Rainbow’s cock had left your mouth to go back down your throat.

Back and forth Rainbow thrust her hips, her cock coming in and out of your mouth each time.

Her all powerful god horse cock made sweet love to your body. You moaned in utmost bliss as her mighty cock made sweet love to you.

Over and over again, her cock made sweet love to your body, pounding your insides and making your whole body shudder in bliss as you moaned in ecstasy. Yours and her moans filled the room, she rode you without stop, her big, blue heavy balls slapping against your backside with a wonderful sound of flesh slapping against flesh.

Rainbow nickered loudly before suddenly picking up the pace, violently thrusting into you. You cried in a mix of both pain and pleasure as she rode you like a jackhammer. You shuddered, moaning in bliss at the feel of being rode like no tomorrow. Her mighty endurance ensured she could go for a prolonged time without stop.

You lay there, helpless as she rode you without mercy, pounding into you with her big fat cock, massaging your entire body and causing you to shake uncontrollably in pleasure. You were lost to the world in pleasure, seeing literally rainbows flashing over your eyes.

Eventually, after prolonged pounding you felt her cock begin to grow even larger inside you, making you scream, before she exploded inside you, filling you up with vast quantities of her essence. Spurt, after spurt of her rainbow cum flowed into your body bloating you out like a balloon, by the time she had finished you were more than a miniature blimp.

"When you deflate you can ride me, Anon." she said softly.
