Headmistress has agreed with Miss Stevens that she will cover her private Physics lesson while she is away. She is not overly impressed that she is having to teach Physics to a St Hugh’s student in the very hot laboratory. Headmistress shows you what you need to read, you will sit quietly and read all the work set and she will help where she can. As Headmistress feels her body temperate rise she has to unbutton her shirt which reveals her cleavage and when you call her closer to try to help you can see right down her shirt. You are so close you can see her shirt buttons strain under the pressure of her bulging cleavage. Each time Headmistress goes back to the front of the class you seem to need help again, this wouldn’t be to do with her having to unbutton more to cope with the heat would it? As Headmistress fans herself with her hand she knows her ******* are bouncing but she is past caring, she even removes her bra from underneath hoping it will cool her down but instead her ******* are just free to bounce even more. When she is close to you again she notices that your hand is under the desk and when she peers over it is obvious you are playing with your **** inside your trousers! She finds this very amusing, you are pathetic, a little bit of bouncing ***** down a blouse and your are tugging away. She laughs and decides to let you jerk that **** inside your trousers like a pervert. You will *** inside them and then you can sit through the rest of the lesson with that sticky mess pressed against you.
