6 months to the end of term.

17-year old Rebecca had had enough of Mr Williams making the girls do unspeakable acts to get better grades.

She decided to teach him a lesson in humiliation.

With the aid of a little bit of black magic she stole his body and stuck him in hers.

She told him he had to be a good girl and do what she said or he would never get it back.

Mr Williams was not too happy that he had his body stolen but told her there was nothing she could do to him that would make him not want to be in this body.

She just looked at him and said well as far as I'm concerned you're failing all your classes and as you know my parents are very strict and have already informed the school that if I don't do good this year they're sending me off to a nunnery.

So you can come and see me everyday for a little bit of tuition so we can see if we can improve your grades or you can go home as me with bad grades and deal with my parents.

The next day Mr Williams who had spent most of the night awake thinking it over as the other girls in the dormitory slept soundly around him.

He turned up to his own office in his first free period of the day for his first lesson in humiliation.

Rebecca smiled as he entered the office and said this is going to hurt you a lot more than it's going to hurt me Mr Williams as she crossed the room and locked the door behind him.

She told him to bend over his desk closed.

He did what he was told and closed his eyes waiting for what was to come.

He felt the skirt he was wearing pulled up and the knickers he was wearing pulled down.

He felt his own masculine hand reach between his legs and cover the pussy he now had in cold sticky lube.

He let out  a sharp squeal of pain as he felt the pussy between his legs spread wide open as he was penetrated by his own cock.

The tiny female body he was now in was shocked by the power of being screwed.

He could not believe how painful and delightful it was at the same time.

He felt after a few minutes of frantic screwing Rebecca emptying into him.

He felt Rebecca sliding out leaving him sticky and wet and dripping.

He felt Rebecca finish herself off & squirt what was left over his buttocks before telling him to get dressed and get out and come back the same time tomorrow for another lesson in humiliation.

He pulled his knickers up, smoothed his skirt down and walked towards the office door before hearing Rebecca say don't forget to take one of the pills I left in my locker for you as we don't want you to get pregnant halfway through term.
