Ms. Banks told the boys what was expected of them

The boys went properly to their seats and sat down, but almost all of them looked angry.

"Good morning! ... Girls!" Ms. Banks greeted them accentuating the girls. "My name is Ms. Banks and I will be your math-teacher. I see you all have received your first, basic therapy, as you all decided to join this class."

"Therapy, my ass." One boy in the first row retorted. "They brainwashed us, so we would come. It's not like we want to."

"Well, then you know that you should listen to what we teachers are telling you. Every defiance could result in you getting punished for it. And that won't be detention or such things, but some messing with your brains or bodies." Ms. Banks stood up. "But there is also one benefit for you." She unbuttoned two of the buttons of her blouse and pulled it open, so that even more of her big, round breasts, the tan line on them and the purple bra get exposed. "This school is filled with a lot of sexy girls and a lot of them wouldn't refuse some ... fun." The boys started to roar and whistle to show they loved it. Ms. Banks walked to the first row and bent over to let the boy before her get an even better view of her cleavage. "How about you? Would you love to get your hands on a nice, big pair of tits like mine?"

"Not just my hands." The boy said and rubbed his hand on the big bulge on his pants. He clearly had a huge erection.

"Good." Ms. Banks smiled to his reply. She unbent and took a step back. "If you want to get a hand, or whatever, on me, or any other staff, you need to do as we tell you. Is that clear?" Most of the boys nodded, only a few looked skeptical. "Good, then I give one simple task, which you have to do until class tomorrow morning." Everyone awaited Ms. Banks telling them what the task would be. Her smile got bigger now that she had their full attention. "Go back to your rooms and put on the uniform provided to you."

For a moment there was silence, then the first boys protested. "You must be kidding! That is for girls!" A fey boys had already noticed the uniform, but they seemed to have thought it was a mistake. Soon all the boys protested.

"Silence, class, silence!" Ms. Banks ordered with a loud voice and soon the boys got silent. "That was neither a mistake, nor a request. Either you put on that uniform until tomorrow! Or you will get to know not to defy orders!" Ms. Banks walked towards you. "This is Alex, a boy doing his internship at this school. Is that right, Alex?"

You blushed and hesitated, but then you confirmed. "Yes. I'm a boy doing his internship here."

Most of the boys doubted that. They said your looks and voice didn't matched a boys.

"You don't believe me?" Ms. Banks walked behind you and reached with both hands around you. You looked down and saw her unbuttoning your blouse before pulling it open, so everyone could see your firm breasts. "Like you, Alex couldn't accept it at first and got these tits as a punishment." Ms. Banks began playing with them. It felt quite good and you began to lightly moan, despite you feeling really embarrassed. Again the boys refused to believe you were a boy and not a girl. "You still don't believe me?" Ms. Banks let go of your breasts and moved her hands further down.

Wondering what she was up to you looked down and nearly panicked. You wanted to protest, but Ms. Banks had already opened the belt of the skirt and pulled it down. Your boxers were revealed, as well as the erection you had.

The boys were totally surprised and shocked by seeing that you really was a boy.
