Teacher

The boy just laughed and lifted something up for him to see. To Arnolds horror it was his badge! It had his full name, a contact email, a photo of his face and even worse the title "Substitute Teacher". The game was up, he was caught.

"Now come on teach, drop those hands or I'll tell the head mistress I caught you jacking it to me in the showers" Arnold gasped as he heard this!

"T-thats ****! A-and its only your work against mine!" he tried to defend himself but the boy just held up something else... the cheeky bastard had taken a photo of him, ass facing the camera and little could be seen but it was clearly him, in the boys locker room with his hands down his front! It looked very incriminating!

"Drop those hands or this ends up on Miss Bitchface's desk" the boy said smugly. "And if you take too long the other boys will get here and you can explain to them why your in here jacking it" He was smug, Arnold had no control.
