He should watch his back

K-T was in a hurry to get to his next class and get a chance to get to his seat before the other students got there. So far he was convinced that sitting down at his desk and not interacting with people was his best shot at avoiding detection. In his haste he missed the wet floor sign in the hallway and slipped.

Bare feet were not the best against soapy tiling, he fell on his back and slid a for some distance before getting back up. This got pretty much everyone in the hallway laughing at him while he got up. Of course while he was sure they made fun of him for falling down he had no idea that his slide had stripped all of the paint from his back. The few bits left were slowly getting stripped by the product used to clean the floor.

K-T didn't look back, not wanting to react to the students making fun of him, and he reached his next class. Sitting was even worse than the last time. Running and his fall had pulled hard on the tape glued to his cock, balls and ass, making it hurt.

He was now sitting in his math class, praying to not be called to the blackboard. Both because he didn't want to draw attention to his current attire and because he didn't prepare his homework. The teacher Mr Price had been informed of K-T's new functions the previous day and he had decided not to point out anything about him to avoid distractions during class, the math level of the school was already low enough that he didn't want to lose any time on nonsense. He wondered though what was the idea to have the boy walk around with clothes painted only on his front side, but he had never understood anything about art.

Of course not reacting to his condition was a reason to excuse him from doing his homework and he knew that K-T almost never did his own. So at the half mark of the class he called him to the board to solve an equation he had to prepare for today.

K-T spent nearly 20 minutes in front of the board, trying to solve the problem directly (he could have used his notes if he had prepared it) and Mr Price wouldn't let him go sit until he got it right. K-T could hear the puffs of laughter from the other students, he assumed were making fun of him for not being able to solve the problem, of course what they were laughing at was his naked backside.

After more hints than should be necessary and almost at random due to so many wrong answers he finally got it right and was allowed to go sit down, still earning himself a failing grade for not having prepared it nor having learned the formula. In the few minutes before the bell rang K-T pondered something that he had not thought about so far. The water he had drank after waking up and the tall glass of orange juice he had for breakfast were reminding themselves to him. He could probably hold it in for a bit longer, but there was no way he could do so for all the afternoon before they would allow him to remove the painted clothes and untape his cock from between his legs.

He checked his schedule, next period was lunch, followed by PE where there was a mark indicating he'd have to participate as a model. Still unaware that he was already half naked he started searching for a solution to his other problem.
