Run
Slowly, you opened your eyes to find yourself looking up at a bright pink ceiling. Alarmed, you sat up... at least tried to sit up, for you felt no feeling from the neck down for some reason.
Fortunately, you could move your head. So you used your only form of movement to survey your environment for danger by turning your head to the left.
On your left you saw a most strange sight, a small red pony lying on his back with thick white bandages wrapped around his rump. The horse had a red mane... and a fully erect penis sanding at six inches tall.
You don't know much about horses, but you were pretty sure that was very small for a horse.
You were surprisingly calm about the situation you found yourself in. So, with that you decided to calmly turn your head to the right... to see a most terrifying sight. A massive blue horse butt with a rainbow tail.
The sheer size of the big blue horse's bubble butt cast a dark shadow over your small form. The horse must have been about the size of a shire horse, if not even bigger. Not only that it appeared to be both female and male, for below her vagina dangled a massive blue cock, thicker than your own leg, along with a pair of balls about the size of basketballs.
Immediately, upon the sight of such a massive terrifying penis you closed your eyes tightly shut, pretending to be asleep in hope of not awakening the behemoth cock into an erection.
A shiver went down your spine when you heard the mare utter a quiet evil laugh, along with the clopping of her hooves.
"Oh, don't worry handsome little human. My friend Fluttershy, is the slow and gentle type, she shall be the first to make gentle, sweet love to your anus, until your butt can take a proper hard pounding from my big cock and all my friends big cocks going up your anus... and your intestines and body in general," she spoke in a hot breathy voice.
For a moment, you simply pretended to be asleep until you felt a mass slam down upon you.
"Ow," you shouted in pain, opening your eyes to see a heavy, meaty slab of long and fat pony cock resting across your chest, standing at a mighty 40 inches long and thicker than your own torso.
"Do you like my penis, handsome ape?" she said sexfully, looking down at you with her huge, rosy red, beach ball sized eyes.
"Uhhhhh, I-I--"
"Don't worry, these big balls of mine shall fill you with so much cum you won't be able to move for hours. You will be filled with rainbow cum, for I am Rainbow Dash," she said sexfully, pointing a hoof down at her massive testicles.
You only made a low whimper of fear in response to that.
"Hah, just you wait! Until you see all my big friends penises. They got even bigger futa mare penises," she said joyfully, not noticing... or perhaps not paying attention to the look of pure terror upon your face.
With that you heard a door slam open, along with a mass of hooves trotting inside. A moment later, your eyes were shown with the horrifying sight of massive horse cocks, standing tall and proud over you, each one bigger than the last.
At the far end of the bed was a pink horse cock which stood at a scary 42 inches long, next to it a orange horse cock stood at an impressive 44 inches long, followed by a white horse cock standings at a mighty 46 inches long, but an even larger yellow cock stood at a fearsome 48 inches long.
And finally, there stood a massive purple pony cock standing at an absolutely terrifying 50 inches long loomed right over your head, casting a dark shadow over you from the sheer size of her cock.
"Hit it, Twilight! Make them even bigger!" boomed Rainbow Dash with a most evil grin on her face.
"Oh yes, our penises are far too small. This sexy human deserves better," spoke a very soft, feminine voice.
"Ah hear ya Fluttershy, this human needs a proper bucking up his cute little apple," came a strong southern accent.
"Indeed, this handsome fellow would hate us forever if we never gave him a proper pounding up his butt with smaller penises," spoke a rich, cultured voice.
"Right on Rarity! I, Pinkie Pie demand we get our penises bigger so we can fill him up with lots and lots of creamy goodness!" shouted a bubbly voice.
"Yes, you are all right, my friends. I, Princess Twilight Sparkle have been taught from Princess Celestia herself that the best way to earn a human's friendship is to pound his anus with unnaturally large penises!" she shouted excitedly.
With that, a dark purple glow surrounded each of the penises as they began to expand in size, thickening outward and growing longer and longer in a manner of seconds.
Not only did their cocks grow bigger and bigger, but their balls inflated out like balloons.
The ponies collapsed to the ground, landing upon their plump massive fat backsides as they became lost in a sea of sexual euphoria, moaning and groaning as their penises grow bigger and bigger.
Thankfully, as if by some sort of divine intervention you could feel your legs once again.
Slowly, you shifted your legs upon the bed, before placing your feet quietly upon the floor and then standing up.
A bright blush came upon your face, realising you were completely naked to the world. You felt really inadequate with a small human penis while being surrounded by giant growing horse cocks.
With that, you quietly tiptoed your way past the massive spheres and long obelisks of inflating balls and growing cocks.
However, you soon noticed that the balls were growing so quick that they were rapidly taking up any remaining space of the room.
So with lightning speed you ran straight for the door, just barely managing to squeeze past a pair of giant pink balls about the size of an african elephant.
You didn't really take in your surroundings, but you did believe you were inside some sort of hospital. Also you jumped out the nearest window, which thankfully wasn't very high.
The sun was high in the sky outside, but you didn't really pay attention to that because you were too terrified.
Your eyes lit up with hope when you saw a forest not too far in the distance.
'Well, I'd rather die in there by being eaten by a wild animal than end up being fucked to death by giant horse cocks.'
So, with that you made a mad dash towards the trees, running past many a thatched house in your wake into the forest to save your anus.
