When his Mistress arrived home, he knew that this evening would turn to a painful torture. He heard it when her high heels stomped strong on the floor on her way to him. And - in fact - she wants to trample his balls just to calm down after work. So she stands on his dick with her soles and her heels, before she starts trampling and crushing his penis and balls with her sharp heels. He can't help himself but gets a boner, and this is much more painful!
