Continuous Milking

A slave has been chained up to a milking machine for 8 hours and has been made to cum 5 times already. When Effie shows two of her friends round her dungeon they want to know if the slave can still cum from a real hand. They detach the machine and the slave rejoices, thinking his ordeal is over - but the girls just jerk him off with their hands instead! Its not long until he has yet another orgasm before they reattach the machine and leave him to suffer his continuous cumshot hell.
