A young rabbit girl laid within her cell. She stared with fear and anticipation at the roof, she knew she needed to rest, but could not. Today was her big day, the day of her ceremony. Where she was to show that she was a big girl, and be capable of being potty trained. If not, then her short time in this twisted realm would end like so many others before her, unable to learn before reaching a certain age.
The cell door creaked opened, making her sit up on her cot, and stare towards the door. 
“Alright young one it’s time." One guard said gently reaching out a hand. 
“we know you’ll make our village proud, sweetheart “said the other in an encouraging tone.
As she stood up she could feel as tinge of deep embarrassment coming over her. While the two guards were dressed in their ceremonial attire, deep aqua robes with swirling patterns embroidered on them. She had recently had her clothing and diaper taken from her, leaving her naked except for a loin cloth that only covered up her vagina. She could feel herself growing hot from blush, but another sensation was coming over her. A growing heat in her lower body. Was this her body telling her that she needed to go or something else entirely?
The guard who offered the encouraging words noticed the young woman’s confusion, and placed a hand on her shoulder. 
“It’s OK sweetie, it’s natural to be afraid, I had to do this myself, I wasn’t able till get it right either until I was a young adult like you.  But once I got on the stage, I was able to do it and continue to do it. Now let’s get you to your potty big girl!" 
The young rabbit took a deep breath and placed her hand into that of the other guard and allowed herself to be led from the cell. The tension was high as they led her down the dimly lit corridor, murals depicting happy anthros using the toilet lined one side of the hall, on the other though a much grimmer event. It shown villagers failing or refusing to be potty trained, they either wore diapers like she had up to this point, or just having accidents. They were shown being placed up a massive toilet, and were flushed down it into a watery fate. This was to be her fate soon if she couldn’t go.
Finally, the lights grew brighter and she could hear the sounds of an excited crowd ahead of them. Her eyes adjusted as they stepped into the arena and the crowd cheered for her arrival. But despite the jovial nature of the scene, her blood ran cold and hair stood on end when she saw what was ahead of her.
Before them in the center of the arena stood a massive stone toilet basin. It was painted in bright almost welcoming colors, this was contrasted the dark wooden platform built around it, giving the toilet strange gallows like appearance. They began their ascent up the ramp towards her destiny. She’d watched countless villagers make this same walk as her with her family, many went up to the platform. But less came back down this final thought, got her heart racing and the strange heat in her body growing once more. 
Once they climbed up the ramp she stood before two figures, the village elder who was dressed in a bright red robe, and the trainer a menacing figure of a woman dressed similarly to the rabbit girl. Only wearing a loincloth and a large black hood that obscured their appearance from everyone else.  
Behind the pair waited the seat on which she was to be given her final chance on, a wooden box with a brightly colored potty seat in the middle, precariously placed on a platform above the dark indigo maw of the toilet below, help up by several attached ropes in a similar fashion to a dunking booth. 
The guards began to push her towards her morbid potty chair. Then the elder spoke.
“Dearest family it is with great reverence we reach this trying time again; a young member of our flock has struggled and must be given this one last chance to prove she is capable of taking care of herself. The village has maintained these rules for generations one must learn to Go on their own or they must Go to our holy whirlpool goddess. “ 
Upon the utterance these final words a low rumble could be felt coming from the toilet as if in anticipation shaking the platform the girl had been moved onto. Is it waiting for me the rabbit thought.  This might have been her imagination but the once still waters now had ominous ripples moving across its surface.
The elder approached her now, gently placing her hands on the girl’s shoulders before saying in a warm tone, 
“You can do this dear"
“I I can do this” the young girl repeated
After she nervously repeated this back to her elder, who gave her a warm smile and took her towards the potty. She placed her exposed posterior towards the seat and while still holding the elders hand sat down upon it. The smooth texture was cold on her ass and she shivered nervously. The elder gently kissed her forehead and began to walk away she nodded towards the trainer who moved to stand beside a rope hanging from the roof of the room and a table that contained a roll of toilet paper and an hour glass. The trainer placed their hand on the hour glass flipping it over so the sand began to flow towards the pattern of a skull swirling in a vortex inside it. 
“Time to go little one make us proud! “the trainer said coldly
The young rabbit concentrated, she had to do this it was her last chance.  She strained desperate to start peeing, she could feel drips coming from her pussy but not the torrent she needed to pass. She looked out towards the crowd, many watched on with faces of worry and sadness. Some however had what looked like expressions of sadistic glee, but many were knelt in prayer for her success. This did not help her, making her body hotter and plight more obvious.
A low rumble came from below, much to her fear and horror the water had started to spin. It started slow but soon turned into a raging vortex, filling the room with the deafening sound of a flushing toilet. 
“Please p-please just let me do this" the rabbit whispered to herself. 
Her face became flush from embarrassment as well as fear. Her bladder strained as she desperately pushed, one little stream even just a tiny amount would be all that was required to save her. 
She placed one hand onto her labia, maybe this would help, and spread the lips. Unfortunately, this did anything but help and sent a foreign feeling shocking through her body, that left her breathless and dizzy, sat upon the precarious potty in a stunned haze.
When she regained her composer, she looked toward the hourglass, it was nearly empty the last grains of sand starting to spill away. 
“No!” she cried “please give me another chance, I’m trying I really am. Please I’m sorry!!” 
The priest shot her a solemn look as the trainer beside her gripped the rope with trepidation. 
“I’m sorry little one, you know the rules. If you can’t go Properly, then you have to Go.” The priest said in sorrowful monotone voice, before nodding at the anthro to her side.
With a swift movement the rope was yanked. A mechanism could be heard spooling up above the bunny and the sound of flushing somehow grew more intense. The girl began to scream and panic. Desperately moving around on the potty seat.  Then she felt something a warm feeling from below. A small yellow stream was exiting her, she had done it. But it was now too late, as the platform started to fall.
The girl screamed as it tipped forward, throwing her towards the now violently raging vortex of water. Within seconds she tumbled towards it landing with a violent splashing, coughing and sputtering she struggled to stay above the icy torrent. But it was in vain as she soon began to lose her equilibrium from the intense spinning water. Round and round she spun with in the flushing toilet, until with one swift motion the rabbit disappeared down the drain with little fanfare just a glug as the basin took the last of its water into the dark oblivion with her. 
The room grew silent, except for a few sniffles, and the villagers began to leave the arena. The priest knelt down before the vortex and said a prayer for her fallen flock member. She then approached a memorial on the opposite side the of the room. 
Above it read the words “Let those who have gone to the goddess not be forgotten” 
She placed her hand on the wall, and glowing rooms soon formed in a blank space on the wall forming into the name of the now devoured young rabbit, another name of the hundreds who found out it was their time to go.
