Your cock is so sensitive, because you're a dirty bitch in heat. I only need two fingers to drive you crazy, that's enough for me to make you blow your load. It will becomes unbearable for you to feel my fingers run up and down on your penis, brush against the skin. But you cannot move, forced under the trample box. You necessarily MUST wait my whim, the moment in which a simple squeeze of the fingers, an imperceptibly faster move of my hand, will literally make you erupt out all the sperm.
