Celestia - Big Mac contest (PISS)

>Celestia walked into her chambers, giving her guards strict orders not to enter, even if she could be in trouble.

>She would need some private time for this, and she cast a privacy spell on her room.

>The windows became tinted, and although she would still be able to see the outside world, none would be able to see inside.

>She had just came back from a meeting, one that had narrowly escaped from intact.

>The meeting itself was boring, the highlight of the event was one of the guards collapsing, bladder emptying itself after a brutal 12 hour shift.

>The warm yellow liquid, draining from gaps in the armor...

>Oh that sweet sweet nectar...

>It was a closely guarded secret, not even luna knew.

>Nobody knew about her watersports fetish.

>Horn glowing, a picture of her bladder appeared before her.

>It was her bladder, and it was brimming full.

>She had already started leaking on her walk here, and it had since grown into a slight stream.

>Shaking her flank, she felt the piss filled organ shake inside her, demanding relief.

>She brought her hoof to her pussy, feeling the wet labia of her body.

>Giving up all self control, her bladder erupted, sending a torrent of piss out of her.

>He hoof somewhat blocking her pussy, forced the torrent to spray out in all directions.

>The urine sprayed everywhere. The curtains, the walls, the floor, her bed, It did not matter to her.

>Her hoof, fighting against the stream, began to work its way inside her pussy.

>Slowly she began to pleasure herself, her hoof slowly making circles.

>Using a bit of energy, she begins to force the urine out of her bladder, doubling the intensity of the stream.

>She climaxes, sending a shower of magical sparks into the air.

>Finally her flow slows, and she is left lying down in a pool of her own fluids.

>After a few minutes, she gets up off the floor. Her coat has soaked up most of the fluid, but the smell still lingers in the air.

>This was the glory of having the biggest bladder, her stream could not be rivaled.

>Or maybe it could, having been the ruler of equestria for several thousand years, she got to see ponies change. See them adapt. See them evolve.

 

>A quick flash of her horn sends a pulse throughout her kingdom.

>It would penetrate every living pony, and show the average amount of fluid their bladder could hold.

>Slowly but surely, numbers came.

>Anything over a litre would come up, and anything under would be ignored.

>A few ponies came up. Spitfire, Rarity, Luna...

>Waiting for the spell, she begins to magic the liquid out of her coat and room.

>Levitating the floating ball of cold liquid, she stares at it for a brief moment more.

>And then she pours it into the toilet. Flushing it away forever.

>The spell flashes dead, having done it’s job.

>Looking over, she see’s only one more addition.

>Big Mac.

>2.7 litres.

>That was the biggest bladder size there by far. Bigger than luna’s.

>It might be even bigger than hers.

>A wave of dread waved over her.

>She loved her bladder, the feeling of it full, the release it gave her...

>The idea that a simple mud pony could ever dare try to out do her!

>A smile stretched across her face, she would put it to the test.

>A contest.

>Drinking as much as you could, and then being scored by how long you lasted, how big the stream, and by volume.

>Yes, a contest would do nicely. Then she would see who has the largest bladder.

>But for now she needed to practice. And have her engineers come up with a diluted liquid, one that would shorten the contest to no more than a few hours at best.

>Soon, she would put Big Mac to the test.
