My rubber slave made a mistake some time ago. He jizzed without permission and without being asked. I remember such things and now he will pay for his mistake. I will treat his cock VERY intensively with my Venus 2000 milking machine. Agonisingly slow, tight and then extremely fast again... I overstimulate him and his best piece with full sadistic lust. Again and again I hold the vent of his gas mask closed, teasing him with words and ideas until he becomes desperate and begins to beg and plead for mercy. Will he obey my rules this time? Or have I come up with another diabolical plan?
