Today I'm teaching a new technique in our self defence class, kicking and kneeing your attacker in the cock and balls, one of my most favourite and effective techniques. After demonstrating for a while, I notice you're not fully concentrating, I send the others out of class to practise next door, while I try and find out the problem with you, turns out your cock has been distracting you, the view up my skirt of my white flimsy panties, and the idea of ball busting is turning you on. I can only think of one way around this and instruct you to pull your trousers and pants down and take care of your cock while I demonstrate some more, I get annoyed you're not cumming fast enough, despite my generosity, I demand you spread your legs and use your balls as my target.. it doesnt take long until you cum over my knee.
