Pinkie Pie's parties are always hotspots of activity in Ponyville whenever she throws one, and this one was no exception.
What had started as small gathering consisting of just yourself, Pinkie Pie and her closest friends had quickly escalated as more Ponyvilleans decided to party crash.
When Vinyl Scratch showed up bringing her DJ equipment, things really took off and soon the Sugarcube Corner had turned into a booming night club.
 
You aren't sure if it was some of the party snacks that didn't agree with you, or just the combination of all the strange liquors you had imbibed, but whatever the reason you now found yourself sitting on the can with a mild stomach ache, hoping that the worst was over.
You could still hear the bass of the disco music thundering through the building from the party still going strong downstairs.
You had just started contemplating getting up when all of a sudden a pink blur came crashing through the door.
"Sorry Anon, but it's an emergency! Spread your legs!" a visibly inebriated Pinkie Pie slurred as she continued to charge towards you.
 
----------------
 
Before you could fully comprehend what was happening, she had leapt into the air, and doing a 180 degree turn in mid-air landed with her rump in your lap, burying your face in her poofy tail.
You only barely had time to move your legs apart before a veritable waterfall erupted between your legs, showering your shaft with a force you would not have thought possible for a pony mare - or any woman for that matter.
The pungent, but not altogether unpleasant smell of concentrated horse piss rising up from below begins to invade your nostrils.
Your cock responds to the ruthless onslaught of pleasantly warm fluids pounding your shaft and balls by immediately starting to harden. Rapidly.
Soon, it began to rise up between Pinkie's legs, disrupting the torrent of fluids and sending it spraying all over the place.
"Oh my, you're a naughty boy aren't you, Anon?" Pinkie chirps, finally taking notice of it. "You like being tinkled on by auntie Pinkie?"
 
Before you can reply, she spins around to face you, lifting herself slightly and positioning still violently gushing vulva directly above your rock hard erection before dropping back down and impaling herself on your throbbing member.
You would have thought that the pressure of your cock against her urethra would have slowed the flow, but if anything the flow seemed to have increased in force as it now gushed violently out around your shaft, hammering your balls more forcefully than ever,  before splashing into the bowl below.
The sensation is unlike anything you've experienced before, with the closest comparable thing being standing with your crotch in front of a water jet at a swimming hall.
You know you won't last long like this, as each splash of urine pounding your crotch sends waves of pleasure surging through your body.
You can feel a powerful orgasm building up in your loins, preparing to unleash itself inside the pink pony mare.
 
-------
 
 
Just when you thought it couldn't get any better, Pinkie looks up at you, a mischievous glint in her eye as she begins to bounce herself up and down, humping your cock with her flow going stronger than ever.
You are amazed as you realize that she's been pissing like a fire hose for what feels like several minutes straight and wonder if a dimensionally transcendent bladder is also among the many unusual and inexplicable powers she seems to possess.
Soon, all thoughts are momentarily erased from your mind as you climax with the force of a thousand elephants, involuntarily grabbing the pink mare and pressing her firmly down against your crotch.
A tiny fart escapes her, causing her to giggle before turning into a moan as you feel your balls contract, shooting a veritable geyser of sticky white stuff inside her hot spring.
You feel her insides clench down on you as the sensation of your cum filling her up pushes her over the edge, causing her to lose control of her bowels and let out a resounding wet fart.
At that, she breaks into a fit of uncontrollable giggling and moaning as her insides massage your shaft, the contractions causing her urine flow to become erratic.
You feel a mixture of what you presume to be marecum mixed with your own starting to seep out around your shaft before getting flushed away by sporadic eruptions of piss each time she breaks out a laugh.
 
As her orgasm subsides, she slumps down on your lap, limp with exhaustion, her face resting against your chest.
For a while, you just sit there waiting for her to say something. As you start to release your grip on her, her head lolls backwards, her mouth wide open, complete with a trickle of drool running down her check, and letting out a loud snore.
If you had been a character in an anime, a large drop of sweat would have spontaneously formed on your forehead at this point.
The drunken bitch had fallen asleep with you still inside.
 
-----------
 
Just then, a deep compassion for the mare resting limply in your lap flares up inside you, and you decide to get her cleaned up.
Mustering all your strength, you return her favor by releasing your bladder inside her, flooding her cave and flushing out the gooey reminder of your union.
After finishing up, you pull out of her and give her a quick rubdown with a warm washcloth to get the sweat and stray urine out of her coat, lest she smell like a public restroom in the morning, and carry her into her bedroom.
Exhausted, you lie down on the bed and are quickly overtaken by a deep slumber.
 
THE END
