My slave can only helplessly look in fear as I bound his encased body with my rope. I whip him repeatedly over his belly, legs and cock. Next, I turn up the power and direct my attention to his hard cock. I don't want him to feel any pleasure with his prick. I just jerk him until he ejaculates the desired amount of sperm, even though I can see he has more. Though I don't allow it, he explodes on his belly and finally I feed him with his Sperm.
