Mrs. Kunt needs to grade her papers.

Mrs. Kunt spoke up. "John, I have to grade some papers before first period starts." She smiled at me kindly, still stroking my cock, but softly now, almost reassuringly, "but I want you to keep masturbating until the end of homeroom, and for the rest of the day, like Nurse Olivia said. Are you going to be okay?"

"Yeah..." I managed to get out from between clentched teeth. The urge to pee was growing stronger and stronger every moment.

"Good," she said. She stopped stroking and gave my dick a pat on its head as if it were a dog. "Just tell me if you need anything."

I nodded yes as best as I could manage, as she stood up, putting the stool back in the corner before returning to her desk. I tried to continue jerking off, but this only made my need to pee even a more central focus.

Finally, despite there being less than ten minutes left in class, almost only five, I couldn't take it any longer. I had to go to the bathroom immediately. I shot a hand up in the air and immediately Mrs. Kunt acknowleged me.

"Mr. Doe?"

"Buh... ba... froom?" I could barely speak, I had to go so badly.
