Today had been yet another pointless day where you achieved nothing.
You spent this day playing video games, watching TV and masturbating to normal human porn. Unlike your brony clopper Internet friends, who masturbated to superior My Little Pony porn, porn that was vastly superior to boring human porn.
You lay in bed fast asleep, just after you masturbated to boring human porn. When you came, you drifted off into blissful sleep.
Nothing could disturb you now, your home was locked tight, even your bedroom door was locked. Nobody could enter your room now.
…. but then there was a blinding flash of light.
You groaned as you opened your eyes to see the huge, towering, alabaster alicorn known as Princess Celestia standing next to your bed. Her back was to you, which gave you a perfect view of her enormous butt. Her massive butt was so plump, so round and so smooth.
Unfortunately, you were not a clopper, so you did not find the white pony goddess sexy.
"Hello there handsome human!" she said sensually as she looked back at you with bedroom eyes.
"Uh, am I dreaming?" you said in a most bewildered voice.
"No, my little human. You are not dreaming," she said as she shaked her huge butt a little before you.
"Ok. But why are you here?" you asked with a raised eyebrow.
"Oh, isn't it obvious?" she said sexfully, before a nasty grin formed on her face.
You shook your head from side to side.
"I'm here for human on pony buttsex!" she shouted excitedly as she rubbed her butt against the side of your bed.
"What?!" you shouted with wide eyes in alarm.
Celestia sighed sadly before she lifted her tale to reveal her beautiful pony pussy and butt hole.
"Anon, you must cum inside my butt to save humanity. You are the chosen one to cum inside my butt to save humanity," she said in a low voice as she looked at you with pleading doggy eyes.
"But but.... but I'm not a clopper. I don't like pony butts!" you shouted as you crossed your arms angrily.
"Heresy! Every human, deep down wants to fuck my butt!" she shouted with narrowed angry eyes.
"Yeah well, I don’t like pony butts! Deal with it!" you said as a nasty smirk formed on your face.
Celestia turned around to face you, her large magenta eyes stared pleadingly into your own.
"Please human, you must cum inside my butt. For cumming inside my butt is the only way to save humanity," she said in a low voice.
"Why?"
"Because if you don't cum inside me, my magical pony butt will not be strong enough to protect humanity!"
"I mean why? Why should I cum inside your butt to save humanity?" you asked in a harsh tone.
“Oh, don’t tell me you're a misanthrope?!“ she said with wide eyes.
"Yes! Because all humans are evil and you ponies should commit xenocide on all evil humans, by turning all humans into ponies!"
“And miss out on glorious human on pony buttsex? Marehood finger banging and belly rubs with your amazing hands! I think not!“ she said crossly as she glared at you angrily.
"But ponies have bigger penises than humans!" you argued.
"Nu-uh! I had sex with Commander Shepard! And besides, I love a human woman's breasts!"
"At any rate, you ponies should kill all humans! Because human are all evil and-- she stuffed her right hoof into your mouth.
"Shut up! Ponies can be just as evil!" she shouted, glaring daggers at you. "Now... " she pulled her hoof out of your mouth. "Are you going to cum inside my butt or not?"
"No! I don't want to cum inside your butt Princess Celestia!" you shouted as you glared at her angrily.
"Is it because I'm a pony?! If I was a human would you be having sweet buttsex with me now?" she shouted as her eyes glowed bright red.
You rolled over onto the opposite side, in order to look away from her.
"If you were a human! Yes, I would gladly have buttsex with you! But you’re not a human!" you said in a harsh tone.
"You are a fat, ugly, oversized, talking horse!" you roared.
The silence hung in the air, the only sound was the gentle clop of hooves.
You sighed in relief that Celestia was going away. However, for some reason your heart skipped a beat when you heard a quiet sniffling sound.
You sat up… only for your heart to begin pounding in your chest as you saw the shaking form of Celestia crying silently to herself in grief at the foot of your bed.
"Celestia?" you said softly.
You got out of bed and ran over to the massive mare and picked her up…. tried to pick her up at least. You could not lift her sheer weight, thanks to thousands of years of eating fattening cake.
You did not notice the sly grin on her face as you gently rubbed a hand through her mane in an attempt to cheer her up.
"I'm sorry Celestia, I didn't mean to hurt your feelings."
"You don't love me! You don't want to cum inside my butt!" she wailed in grief.
All of a sudden, a spark of passion overwhelmed you, which resulted in you gently placing a hand on her right buttcheek.
"Maybe… maybe… I could learn to love you and your pony butt?" you said in a low voice, unsure of buttsex with a pony.
Celestia stood up, before she turned to face you with bedroom eyes.
"Oh don’t worry, my little human. You will worship this butt after tonight," she said with an evil grin.
With that she picked you up, before she carried you onto the bed. Once you were there, the large mare straddled herself over you. Her heavy, massive butt pressed you deep into the mattress.
"Ah… you’re too heavy Celestia!" you said in a low, raspy voice under her crushing weight
With a small flash of her horn you no longer felt any pain from the massive mare now lying atop you.
"Hmm! I should have let my huge butt crush you, after how mean you’ve been to me," she said mischievously as a nasty grin formed on her face.
"I’m sorry! I was wrong! I was in denial! Your butt is so big and amazing!" you shouted as you looked at her with fear filled eyes.
"You really hurt my feelings there. I feel like I should let my massive butt crush you from under me," she said as she looked down at you with narrowed angry eyes.
"Please no!" you shouted in panic as you began roaming your hands over her massive, bountiful, silky soft cheeks.
You soon began to tightly squeezed her butt here and there, the applied pressure from your hands compressed the silky soft fat of her massive butt. Each time you squeezed her butt the mare atop you groaned lustfully in approval.
"See? I worship your butt now! As a mortal, I am not worthy of such a fine butt!" you shouted.
A nasty smile formed on her face.
"Very well, puny human! Your kind words and butt rubbing have persuaded me to give you another chance," she said as she looked down at you with bedroom eyes as you felt an odd feeling between your legs.
You sighed in relief, just before you felt a tingling sensation as your boxers were lowered to reveal your buttmagic magically enhanced penis, which stood tall and proud.
"We don't have much time! You must cum inside my butt before it's too late!" she shouted with wide panic filled eyes.
With that she positioned her massive butt over you, before she took the thick tip of your cock inside her butthole. You groaned lustfully as the massive mare slowly sank down upon your long and thick shaft.
"All fall before my mighty butt," she said with a nasty grin as she descended upon you.
You groaned in pure ecstasy as Celestia continued to lower herself atop you. You could not help yourself but to lean forward in order to tightly squeeze her massive, amazing butt. The soft feel of her butt put the finest silks to shame.
As the last few inches of your long, towering massive cock became buried deep inside her butt, the huge mare atop you had leaned forward to bring you into a passionate kiss.
Her soft, plump lips pressed against yours as her large tongue danced with your smaller human tongue in a tender display of human and pony love. Before a moment later, she began to bounce her enormous butt atop you all the while she moaned aloud as she kissed you deeply.
You cried out in delight as her gigantic butt slammed heavily upon you, your long and thick cock was hugged tightly deep inside her butt’s amazing embrace.
The huge alicorn mare continued to bounce herself down harder and harder upon you to the point you thought your pubic bone could break at any moment.
Soon, you had no fear of that happening, for you knew at that moment Celestia’s magical butt would never hurt a human from under her. Her butt was for loving humans, not for hurting them.
Your grip on her butt tightened, the soft fat of her butt compressed to the applied pressure from your hands. You, the poor human were getting close. Her all powerful butt demanded your seed to be unleashed inside her.
"Come on human! Cum inside my butt before it’s too late!" she shouted in panic.
You squeezed her beautiful, massive white bubble butt with new found resolve. You were the chosen one, the fate of humanity was at stake, thus you began to thrust upwards into her massive ass in order to meet her butt in time with her bounces upon you as you became crazed with lust.
"You can do it human! I believe in you!" she shouted in encouragement.
"Hah! You’re too late Celestia!" came a deep evil voice.
"Oh no, it’s Lord Darknessmarkness Narkness Blurness!" she shouted in panic.
There was a blinding flash of light, followed by a huge red and black alicorn with glowing red eyes and an evil grin on his face as he stood before the foot of your bed.
"Mwahahaha! When I destroy all of humanity there will be no more human on pony buttsex ever!" he said evilly.
"Noooooooooo!" she screamed in horror.
Just when all hope was lost, you came inside Celestia’s butt. Your cum blasted into her butt. Her butt glowed with rainbow light.
"What?! No it can’t be!" he roared as he fired two red laser beams from his eyes at her butt… which had no effect on her butt nor the human softening cock still deep inside her.
"Hah! I am the overpowered alicorn here now! Unlike you, I’m not an evil cunt that abuses their overpowered pony magic" she said with a nasty grin.
"No! I am still more powerful than you!" he shouted in anger as he stomped his hooves.
She took a deep breath. "BEHOLD, THE POWER OF MY SUNBUTT!" she roared in the traditional royal canterlot voice as her butt glowed in blinding light.
"Nooooooooo!" he roared as his body was vaporized by a rainbow particle beam blasting out from her butt.
You sighed in relief. "We did it, your butt saved humanity," you said as a happy grin formed on your face.
"It was my pleasure," she said softly before she looked down at you with bedroom eyes.
"Now, I want more human on pony buttsex! Your magical human cum makes my butt stronger and stronger!" she said lustfully as she used her magic to re-harden your cock and refill your balls with cum.
"So… the more times I cum inside your butt. The more powerful you shall become?"
"Yes, the more cum your human penis offers my glorious butt, the more my magical powers will grow ever more stronger," she said as a nasty grin formed on her face.
And then you had even more buttsex with the overpowered alicorn. Her butt and magical powers only grew more powerful every time you cum inside her butt. So many times you came inside her butt tonight, the power of your cum gave the god pony the ability to easily take over the entire universe… if not even hundreds of other universes as well.
A time will come when another human will have magical cum to make Celestia's glorious butt even more powerful. But that is a tale for another time.
