Humiliate him completely in front of everybody

You take his wrist, bending it in an unnatural position. He is **** to follow your pushing and roll up side down, making painful noises during the rotation. You land on his back, crossing your feet under his arms and blocking him face on the ground. He squirms "Please Sarah..don't do anything..I submit..". He has understood your intentions and is so scared that is almost pissing in his pants. Unfortunately for him you are merciless; closing your tights in a reverse armlock you lean forward, rising your hands over his ass. "You are stronger Sarah!!" he screams fearfully, "You are better than me..please stop..". "You are a spoiled little child Josh and you need to learn manners! If our parents have failed with you it is up to me then..", you retort coldly. Holding him still you start spanking his little ass in front of everybody. He cannto help but cry, probably suffering the worst humiliation of his entire life. After a minute or so you stop, letting him run away. He will be destroyed by this experience, which will upset his mind for the years to come and will make him drop the martial arts's world forever.
