Kim, your former bully

As the principal finished her sentence, the bathroom door opened. You glance over towards the door and your heart sinks; it's Kim, a girl that used to relentlessly bully you when you were younger. Kim looks over at you and smiles evilly.

"Oh. Hello Kim," the principal said.

"Hello ma'am," replied Kim, still smiling at you. "Is this our new toilet?"

"Yes it is," replied the principal, "we just had it installed, although it may require some maintenance based on its initial performance."

"Well," replied Kim, "I really need to use the restroom. Do you two mind giving us some privacy so I can test it out? I can report back afterwards with my review."

"Of course Kim," said the principal, "that would be great. Come on Violet, let's give Kim her privacy."

Your heart is pounding as you watch the principal and Violet leave the bathroom. Your newfound enthrallment of futa piss can only go so far when the girl who traumatized you for so many years is the one who is serving it. You also realize that Kim has full power to make your life a living hell if she reports back to the principal that you were a bad toilet for her, so you'd have to overperform as best as you could.

"Well, well, well," said Kim, walking up towards you. "All of those years of making you lick my shoes and making you drink my spit are looking pretty good right about now, aren't they?"

"Hello miss Kim," you respond, trying to sound confident, "how may I serve you today?"

"Well," said Kim while her smile widened, "I did have to use the restroom. But I think before I do that I might have a little orgasm first. Post-nut pee always feels better than regular, you know?"

Kim pulled out her member in front of your face. Even though it was significantly smaller than the principals, it was still much larger than yours. Maybe all those years of bullying were justified.

You open your mouth to begin sucking, before you hear Kim's voice. "Toilets do not give head. Toilets only act as a disposal for cum. Keep your mouth open and as close to the tip as possible, but if you touch me I won't hesitate to tell the principal that you're not up to proper toilet standards."

You do as asked, opening your mouth under the tip your bully's member. Kim grabs it and starts stroking. She continues to stroke silently for a few minutes, before you hear her speak again.

"I'm close to cumming toilet, so you better be ready," said Kim. "I always knew you were scum, not even fit for a task designed even remotely close to what a human would be useful for. I should have traumatized you more back then, it would have served you well for this moment."

Just as she finished speaking, a hot load of cum came shooting out of her member and into my open and ready mouth. You tried to swallow as fast as you could, but more and more of it came shooting out. Finally, you manage to get it all down and into your stomach, but you're barely able to breathe.

"Thank... you... miss... Kim..." you managed to stutter in between sporadic breaths. You took a moment to take in a couple of deep breaths to get your breathing under control. "How else may I serve you today?"
