You become Kim's personal toilet

It's been several days of being a public use toilet for futas. Your knees are aching. Your back hurts. You've forgotten what normal food and drink tastes like. Yet, you love it. You're in heaven. There is nothing you enjoy more than drinking futa nectar and swallowing futa cum.

Especially Kim's nectar and cum. Oh how you love it. You yearn for it. Every minute spent not drinking the delicious fluid that comes out of Kim's cock feels like an eternity. Yet, you don't understand why. Maybe it's a terrible case of Stockholm Syndrome? Or maybe, just maybe, Kim was right in all those years of bullying... maybe you do deserve to be nothing more than an object for her to use.

Your thoughts are interrupted by the principal and Violet entering into the bathroom. They walk over to you and begin to undo your bindings.

"Hi Doug, er... toilet," said Violet, "a decision has been made to make some adjustments to your situation."

Violet and the principal both stand you up.

"Yes," said the principal, "a new student has been selected to serve as a public toilet, and so that will no longer be part of your duty."

Your mind immediately turns into mush as your thoughts go into a thick haze. Does that mean... you're free? You get to go enjoy life again?

"Ma'am..." you begin, but your sentence is immediately stopped by the principal who puts her hand up.

"This new student was selected," continued the principal, "on the account of you being moved to a... different post. You see, you will still serve as a toilet, but no longer publicly. Kim has been getting amazing grades these past couple of weeks, and has been named student of the month. As such, she will be given her own personal restroom to use, as well as asking for one privilege from the school and, well, she elected to have you serve as her personal toilet next month. It seems you've impressed her!"

You nearly faint, and have to grab a hold of the wall to stop yourself from falling. "Impressed her. Right." You manage to utter.

"Well, come along then, let's get you situated in your new home," said the principal.

Your mind goes into a fog as Violet and the principal lead you down the hall over to the student of the month's bathroom. The 3 of you enter in as you glance around. The bathroom was simple enough - sink on one end, hole where the toilet goes on the other, and a small table off to the side that was attached to the wall, which appeared to contain some whips and other BDSM equipment, as well as a few other mechanical contraptions.

"Kim has specifically requested that you attend to her fully naked," said the principal, "so strip down, and then go kneel inside your hole."

You do as asked, taking off all your clothes and handing them to the principal, before kneeling down in the toilet hole. Violet and the principal fasten you to the wall before promptly leaving.

After a few minutes of kneeling in the darkness, the door opens, and Kim walks in.

"Hello toilet," said Kim, smiling. "This is going to be a fun month... for me, anyway. See, I've noticed that you've been enjoying your position a little too much, so I've asked for you to serve me here instead. In here, it will not be fun for you. No. The fact you've been enjoying my company tells me that you are not being treated harshly enough. That changes today. As you can see, you are now fully naked, which not only displays your submissiveness to me but also allows me full access to your body to do with as I wish."

"Now, let's start things off correctly, shall we? I'm going to break you."
