Well for those who were unwilling or whatever that is where the officers, or students/staff come in that are already broken and subdued to the place.  The main power of this is the sexual enhancing drug.  It makes one addicted to sex as well as boost performance.  So in that way other members of authority could use that plus other methods to break their will and have them submit to the place.  Even if they try to argue or resist at first, as soon as the drug is administered they start to lose control...their body heats up...their sexual organs crave it...so on and so forth.  It would be an underground sort of thing, though a very profitable business as it does deal with leaders and the rich all over.  When government comes in...some are even corrupt and take part in it, others are bribed and what not.
