Do you have everything? If so, I will now train you in some of the basics of being a sex slave. Failing to perform as requested will have varying consequences as you will see later. You may also stroke at your leisure, but if you orgasm, you immediately fail.
Failures don't need to worry about performing well in the future, as their indefinite future will consist of spending 16 hours a day as a secured lump of flesh in the men's room to be used as desired by guests. Such a fantasy may sound arousing to you now, but I assure you those who actually experience it never enjoy it.
