You, a very-very happy human with an insane grin on your face lay naked upon a large pink, queen sized bed. For there was a massive, towering alabaster pony goddess straddled over you. Said goddess was far taller and bigger than you.
The alicorn pony had smooth, silky soft white fur, a long swan like neck, the face of an angel in equine form. The mare had luscious, kissable lips, gorgeous large, feathery wings and beautiful large magenta eyes. A long, white horn worthy of a spartan warrior protruded out from her forehead. Her multicolored, mane and tail flowed in a non existent breeze, which seemed to be made of some sort of magical matter.
All those were needless details. For the most important detail was that this white alicorn mare had quite possibly the greatest, most tremendous and most beautiful fat butt you ever seen in your entire life. Her plump, fat ass was so massive and beautiful it was beyond compare to any other butt you ever saw. The soft feel of her ass put the finest of silks to shame.
As luck would have it, that glorious, bootylicious, royal big fat pony butt of her’s was bouncing on your lap. Her heavy, enormous butt made you lost to the world. The only thing you really cared about was dat ass bouncing on top of you. Topped off with her soft angelic voice, even through the throes of passion with moaning and groaning was music to your ears.
As her butt repeatedly bounced up and down upon you, the hot confines of her vagina tightly hugged your magically extended cock, her slick insides milking you for all you were worth. Her dripping wet marehood made your cock lubricated for the job as it stood tall and proud deep inside her love tunnel.
Your hands could not help but tightly grip the sides of her wide, white marshmallow flanks. Your hands dug deeply into the thick, bountiful mounds of flesh from her buttcheeks. Your tight grip upon her had caused your fingers to dig deep into the thick, soft fat of her squishy soft, enormous rump. Your applied pressure from your hands compressed down the immense layer of fat belonging to her godly butt.
You didn’t just do that though. You would also roam your hands over the wide expanse of her cheeks belonging to her immense bubble butt. With a happy grin on your face you fondled her gigantic ass all over, giving a tight squeezed to her butt here and there.
This huge butt belonged to Princess Celestia, the most big and sexy, immortal interdimensional alien god horse you ever saw. She was a pony princess, but she was also the best booty queen with the fattest butt in all of Equestria.
How did you, a mere human get to tap Celestia’s sweet ass? Simple, after about ten minutes of being teleported into Equestria for some reason you had walked up to her as she was sat on her throne. There, you gave her a belly rub with your amazing hands. Then you offered to hand feed her a carrot out of your hand. She became very happy over this with tears of joy in her eyes, she then quickly wolfed down the carrot, before she dragged you off to her bedroom and things got pretty heated from there.
And then you got to fuck dat ass and god pony pussy!
Truthfully, it wasn’t the perfect experience being under her butt. For this massive, meaty mare was very heavy… very- very heavy. Sure, her enormous butt was the most spacious butt you ever felt up. But she did most of the work, you could only merely hump upward to meet her in time with her bouncing, for the sheer, immense weight of her butt made lifting it with your hands next to impossible. It was just way too heavy for any normal human to lift.
Though, being dominated by a giant female was quite an awesome experience nonetheless.
To show her appreciation on the pleasure she’s giving you and the desire to give this also cute and sexy pony a pet, you thus had lifted your hand to stroke her ethereal mane. It felt amazing and was warm to the touch, yet it still felt somewhat like normal hair, your fingers slid through it like it was flowing water, and you felt a slight tingling sensation course through your hand as you touched it.
You shuddered as you felt her gently brush her ethereal tail over your legs. It seemed clear that she liked to feel your hand rubbing her mane.
You then opened your mouth to speak… but merely uttered a raspy gasp when Celestia had abruptly slammed herself down hard upon you.
"Aaahhhhaaa! Not so rough!" you cried out in pain.
Celestia ceased her bouncing, looking down at you in concern. "Sorry, Anon. Got a little carried away there," she spoke softly.
"It’s Ok! Just… just be a little more gentle," you spoke in a low voice.
Celestia nodded, before she resumed bouncing herself atop you. This shortly followed with her head leaning down, in order to press her lips against your own. Both tongues swirled around one another, gently caressing each other as both human and alicorn moaned in ecstasy, all the while she continued to bounce her massive butt atop you.
The sounds of slapping flesh against flesh along with the moans and groans from her, and her massive glorious butt relentlessly bouncing atop you without pause was becoming too much for you.
You unleashed a loud groan, tightly gripping her huge butt, deeply depressing into the thick soft fat of her butt. "Celestia…. I’m getting close!"
"Don’t hold back, my little human! Cum inside this big horse, you sexy hairless ape!"
With that you groaned in pure bliss as your cock sent forth wave after wave of human cum deep into her glorious magical pony pussy. The sheer volume of your cum became too much, thus both human and marecum flowed out from her pussy to make a terrible mess on the bed.
Eventually, your blasts of cum became less and less, until you finally stopped. Your cock deep inside her had began to soften.
Celestia bounced gently on your softening cock for a little, before she uttered a happy sigh as she pulled out, followed by laying herself down beside you.
You and Celestia cuddled for awhile before you kissed and then went to sleep with blissful smiles on both your faces.
You slept well... until you awoke with a start as a sharp, throbbing pain flowed through your legs. Your legs felt like jelly. You quite literally could not move them without causing agonizing pain, even while remaining still the pain sored through you like a knife.
Thus, you unleashed a loud scream in pain, tears falling down your cheeks.
Celestia opened her eyes wide in panic. "Sweetheart! Are you OK?!" she shouted.
"Aaaaaaahhhhhhhaaaa fuck! My legs! My fucking legs! They fucking hurt so fucking bad!" you shouted in agony.
Celestia’s horn became surrounded in a golden aura, just before you felt a brief, light tingling sensation in your legs. But nothing had changed, you still felt the horrible pain.
"Use fucking better horse magic you fucking bloody cunt ya!" you roared angrily.
"I’m sorry! But the healing spell takes a few hours to fully kick in!"
You merely screamed at her in response. The mare then wrapped her hooves gently around you, letting you cry into her mane as she held you.
"Shh, there-there little one,” she whispered into your ear as she gently patted you on the back with a hoof. “It's going to be OK, the pain will get less and less over the next few hours and you'll be able to walk again once the healing magic fully kicks in."
"Thank bloody fucking hell!" you shouted.
"Oh and I’ll make sure not to break your legs by using weight suppressing magic the next time we have sex.”
"Why the bloody fuck did you not use that the cunting first time you fucking cunting big fat whorse bleedin' cunt bitch ya?!" you bellowed.
"I’m sorry! I didn’t know human bodies were so weak!" she cried, a few tears falling down her cheeks.
You cried out and screamed out more profanity as the pain in your legs suddenly intensified… you now could only scream as tears flowed down your cheeks.
As the hours went by, Celestia continued to hold you close and whispered soothing words into your ear, not ever letting go as she endured your screaming, crying and general yells of profanity about fucking bloody cunts without even a look of annoyance crossing her face. Like a mother with patience of stone, she held you without complaint.
As the hours passed, the pain in your legs, little by little became less and less painful. When the pain finally became a more tolerable level at the break of dawn. You had spoke in a low, raspy voice. "The pain was worth the sex. But please… please cast protection magic on my body next time."
"I will. I’m so terribly sorry. Can you forgive me?" she said in a low voice, looking downcast with a guilty expression on her face.
"Oh, of course I forgive you, you sexy big fat horse!" you said in a raised voice, rubbing a hand through her mane. "Like I said, the pain was worth the sex."
"Thank you for accepting my apology," she said, before she leaned forward to softly kiss your forehead. "Oh and if you call me a big fat horse again, you won’t get any chocolate cake nor buttsex from me for a week."
You gulped nervously. "OK. That’s understood."
