At Highgrove Manor we place the utmost importance on female slaves acquiring the ability to provide long and sustained pleasure service to their owners. That's why they have to go through a hard training in which they are subjected to a wide variety of stimuli without reaching the climax. Only slaves who undergo continuous stimulation at the highest level of 36 hours are eligible to advance to the next level of their training. Slaves who do not reach this level during their three-month stimulus training are eliminated and trained as slave workers.
