Hump MS Daisy's Ass

I have finished writing my test. Mrs Daisy wipes the board and wiggles her butt. I am fascinated by this and have to hug her from behind and rub myself against her. Mrs Daisy is shocked, but I have to do it. I lay her on the desk and take off her skirt and satisfy myself on her ass until it really smacks. Then I make her kneel on the floor and mount her from behind until I cum.
