Headmistress; Inside Blouse Bouncing Breasts

Headmistress has agreed with that she will cover her private Physics lesson. Headmistress shows you what you need to do, you will sit quietly and read. As Headmistress feels her body temperate rise in the hot laboratory she has to unbutton her shirt which reveals her cleavage and when you call her closer 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 cleavage. As Headmistress fans herself with her she knows her breasts are bouncing but she is past caring, she even removes her bra from underneath hoping it will cool her down but instead her breasts are just free to bounce even more. She notices your hand is under the desk and when she peers over it is obvious you are playing with your dick inside your trousers! She finds this very amusing, she laughs and decides to let you jerk that cock inside your trousers. You will cum inside them and then sit with that sticky mess pressed against you.
