The slave gets a hard time, the Nurse wants his sperm,

First She makes sure that he is trapped inside the inflatable heavy rubber bodybag,

Then She makes his cock sensitive and very hard with the terminator, to make sure he doesn't orgasm to early, She is denying and edging his cock.

After that She takes the strong serious kit milker milkingmachine and drives the slave crazy with the speed of the milking.
