The male maid is ordered into the studio by Mistress Silvia. There she has to suffer several nasty procedures. Partly to enhance toughness and usability, partly just to please the diabolic Mistress. The maid has to undergo an embarrassing and painful anal inspection and has to bear electric shocks which Mistress Silvia administers with sadistic pleasure. Finally the male maid has to suck another slave’s cock before the lesson ends with orgasm control and jerking off on command.
