From Princess to Privy (scat)

The sound of dripping water, endlessly falling in an annoyingly, inconsistency pattern was the only thing Celestia hear other than her own pained breathing.

Her cell was without even a shred of light, and she was so far underground that she couldn't hear the ponies above. Or, the changelings rather. She couldn't imagine Chrysalis would allow her pony slaves to use her streets. They would be working elsewhere. In mines or as entertainment. they were just food to her... but useful food.

No reason not to make a heybuger do the dishes it was possible.

As for herself, Celestia wasn't sure, but she was expecting the worst. Chrysalis likely had plans with her. She had made sure she didn't go anywhere, not even anywhere in her own cell.

She was practically bolted to the ground, clamps around every limb, holding her in place. Even her tail was clamped to the floor.

She could do nothing when the Changeling army stormed the city, and she could do even less now.

She lied utterly and completely defeated, just waiting for the Queen to appear.

And eventually, right when Celestia was about to abandon the hope that she would ever talk to another sentient being again... she did.

The sound of hoofsteps approaching outside her cell broke the constant, static noise of her own whimpering and droplets falling.

A door creaked open, and flickering light flooded in. It was a meek, dim, reddish light, made from torches outside in the dungeon corridor, but having laid in total darkness for three days straight, even this amount of brightness was too much for her sore eyes.

She closed them and cried silently as the Queen walked inside, her large hips swaying voluptuously as she approached her restrained prey.

"Pathetic Celestia," the queen cooed as she looked at the former ruler of Equestria, tied up on the ground, eyes closed in pain, whimpering in fear and sadness.

"C-Chrysalis, please!" she cried out, still not looking at her in the, to her, sharp light. "Let my people go. They didn't do anything to you."

Laughing slowly, the Queen clopped closer, and Celestia finally managed to open her eyes.

She looked at the dark looming figure in front her, tall, menacing and majestic.

As the Queen gets close enough, her feminine face became visible in the dim flickering light. She was smiling sadistically, her green, lush lips looking moist from licking her lips lustfully with her long snake-like tongue.

They stared deeply into each other's eyes, Celestia's full of fear, and the terrifying queen Chrysalis' glowing green with cruel excitement.

"Trying to be a martyr after I've already won, Celestia? Well, that's just pointless. Does it bother you, though? You've spent so much time sitting around, letting your subordinates do the work, allowing yourself to get weak and slobby. When your time finally came to fight, when the Elements were separated..."

She leaned in closer, whispering directly into her victim's ear.

"...You were useless."

Celestia cried. Chrysalis was right, she had barely even presented an obstacle for the powerful changeling. The day where her people had depended on her most had come, and she had failed them.

"Please..." she tried again, knowing full well that she could do nothing else but plead.

"Oh, Celestia," she queen giggled. "There's no need to act so pathetically... You already look the part well enough," Chrysalis said, lightly brushing the stub on Celestia's forehead that used to be her horn.

Sensing it was no use, Celestia instead turned to asking questions.

"W-what are you going to do to me?" she asked, shaking in her tight bindings with fear.

It was a question she wasn't sure she had the courage to ask. Turned out, she didn't have the courage not to.

Chrysalis' smile turned ever brighter... crueler... scarier.

"Well, I have a couple of ideas."

Celestia took a deep breath. She didn't want to know, but she needed to.

"A-am I going to die!" she asked slowly, looking up at the changeling with big puppy eyes.

Chrysalis chuckled lightly, the way someone laughs when a child says something silly.

"No," she answered calmly and delightfully.

Somehow, this didn't ease Celestia much. It mostly just made her fear another undesirable possibility.

She turned pale.

"Wi... will I... Will I be... T-t-tortured?" she asked, her voice dripping with fear.

As much as Celestia had turned pale with fear, Chrysalis' cheeks turned red with excitement.

She chuckled deeply, licking her voluptuous lips again.

"Well, of course, you will," she sang gleefully, caressing her prisoner's cheek.

Celestia started crying again, the realization hitting her like bricks.

"P-p-please... I-I beg you, please don't hurt me" she pleaded, even though she knew it wouldn't help her in the slightest.

Chrysalis chuckled yet again.

"Are those really the words of a martyr? You, truly are pathetic. I can barely wait to make you suffer!" she said, putting a leash around the princess' neck.

The clamps that held Celestia pinned suddenly disappeared, allowing her to stand.

And with Chrysalis looking sternly at her, she stood, her limbs aching from after their abuse.

"Come here!" the queen commanded, tugging on her torture slave hard behind her.

Celestia whined as she stumbled after her captor, but she was quick to get back up, as Chrysalis send her a death glare.

Together they walked out of the dungeon and into the caste in silence.

"W-what exactly will happen to me," Celestia finally asked as the two large mares wandered through what used to be her hallways.

"I'll show you in a moment," cooed Chrysalis, and other than her quiet cried and whimpers, Celestia shut her mouth until they arrived.

They enter a bathroom. Her bathroom.

Her eyes widened.

"No..." she said quietly into the air.

During the last three days, the bathroom had been remodeled into a torture chamber... Yet, it was still very much a bathroom.

There was a platform with a shower curtain and various types of soaps and shampoos. there was no showerhead, however.
Instead, there was a pillory to trap a pony in, placing their hard roughly in the hight of chrysalis' hight. But there was a crank that allowed it to be lowered down to hoof-level.

Other than that, there was a seat with two protruding leg-rests to keep your thighs separated and lifted high without sitting uncomfortably. And underneath it, around where the seat's users pussy would be, there were some hooks, that could hold another pony's mouth open wide, and some bindings to hold said pony in place.

Finally, there was a metallic coffin, packed with chains and binding to hold a horse in place tightly... Very tightly, like restriction was more needed for this one than the others. At the end of the open coffin, there was a toilet seat.

There were three devices here:

A shower, a urinal, and a toilet.

Celestia looked up and Chrysalis with begging eyes.

"No..."

The queen smiled.

"You'll be my living bathroom... You'll serve my body. You'll know your place below me. Far, far below me."

Too overwhelmed to even panic, the crying Celestia took one last look around the bathroom.

"No..."
