Detention
I finally managed to write something.
Had to upload to SoFurry because Fur Affinity is broken or something lol
"Welcome to detention."
That's right. I got detention. Just after I turned eighteen. I was about to piss myself and rushed towards the bathroom after the teacher refused to let me go.
Detention. Because I needed to take a fucking leak.
"So, here's the deal," said the Black Kyurem. "You are getting assigned the next homework assignment early. You're not leaving until it's all done. Correctly."
I had to pee again, but I already knew he wouldn't let me go, so I didn't bother asking. My only option was to try to get all of these math problems done, ideally before I ended up with wet pants.
"Um, Mr. Winters," I said. "How am I supposed to finish this? We haven't even covered integration in class yet..."
"I'm sure you can figure it out, Jake. You're the smartest kid in class, right?"
"... Kid? I'm a Palkia, a legendary Pokemo -"
"You and everyone else at this school. Now stay quiet and finish the assignment."
Mr. Winters seemed intent on keeping me here for as long as the school would allow him to. My only choice was to try to use whatever I knew about integrals to try and get the assignment completed. He just sat at his desk grading the latest test, hushing me whenever I tried to ask him for help.
"Uh, Mr. W -"
"I said stay quiet, Jake!"
At this point, my need to piss was really bad. It was to the point where I could no longer even focus on the assignment and to where I was very visibly fidgeting. Mr. Winters took notice of my fidgeting and seemed to look over quite frequently. I could've sworn I heard him unzip his pants, too, but I didn't think of trying to get up to check. Eventually, I got one of the problems finished.
"Mr. Winters? Is this the right answer?"
Mr. Winters got up to walk over to see what I wrote, before which I once again heard the distinct sound of a pants zipper. He looked at my answer and all of the work on my paper.
"Yes, that's right. Only nine more problems to go."
Mr. Winters went back to his desk to continue grading tests. Meanwhile, I looked at the other nine problems, which appeared to be in a foreign language. Furthermore, my rapidly increasing desperation proved to be very effective at distracting me from the problems. Eventually, I couldn't even divert a smidgen of my attention towards the homework assignment; my entire mind was focused only on how badly I had to piss, and my hands were too focused on pressing down on my bulge in a last-ditch attempt to keep even the tiniest amount of pee from leaking out.
"Can't get the work done with your hand on your dick, Jack."
I knew he was right, so I took my hands off of my bulge - and that's immediately when all of my piss started to leak out. I just sat there as I got to watch my pants get soaked with my own urine, which then formed a pool on my chair which overflowed onto the carpet. Mr. Winters watched the whole thing intently, standing up to reveal his erection that he had freed from his pants.
"Goodness, Jake... You really had to go, didn't you..."
"You bastard... This is what you wanted, isn't it?"
"You catch on quickly. Unfortunately, you're gonna need some extra punishments."
He put his cock right up against my face, saying, "Put it in your mouth."
I didn't want to suck him off, but I also wasn't exactly in a position to refuse, so I begrudgingly put his penis in my mouth and started licking.
"Don't spit it out."
He started peeing into my mouth, forcing me to drink every last drop of the contents of his bladder. Thanks to the sheer strength of the salty flavor, I could tell that he hadn't been drinking enough water; it's as if he intentionally dehydrated himself in order to make sure I'd be forced to have a pretty concentrated sample.
"Good," he said as he finished peeing. "Now turn around. Lick all of your piss off of that chair."
Once again, not being in a position to refuse, I had no choice but to comply with his demand. As tears started to uncontrollably drop from my eyes, I licked every last drop of urine off of my chair.
"Good. Now strip."
Still crying, I took off my clothes, setting them in a pile on the desk.
"Put your underwear in your mouth and suck on them."
I put my thoroughly urine-soaked jockstrap in my mouth and started sucking the piss out. At this point, I was just hoping for anyone to walk in - even that dipshit of a Raikou who betrays everyone's trust - just to get this assault to end.
"One more thing," he said, as I looked at him now nude and applying a generous amount of lube to his throbbing member. "It'll hurt more if you scream."
He pinned my chest down on the desk with one hand and used the other to prevent me from spitting out the jockstrap. He then started aggressively penetrating me. I tried to make some kind of noise, but my own pissy jockstrap muffled all of the sounds I could make to an unintelligible mumble. Every time I tried to scream, his penetration got even more aggressive. My only solace was that it was over quickly; he jumped the gun, so to speak, reaching climax in only a minute.
Whatever happened after that point, I don't remember. I blacked out from the trauma.
