Ideally, they should always be happy with the way they are treated; if their Master wanted them to have better food, clothes, less work, and perfume, he would surely tell them; after all, he always has their best interests for them. Any slave that is identified to be discontent or questions her master is immediately returned to the resort to be "re-educated." Reeducation consists of altering the drug formula to get them back to their blissful, happy state. Unfortunately, some slaves develop a tolerance to the drug treatments after years of being on it, so it is better to identify the deviates sooner rather than later. Slaves that build a tolerance to the treatments that can't be corrected by adjusting the dosages are sent to Masters that own dungeons, where they have a hobby in hardcore BDSM and torture the sluts for their sick pleasure; these rebellious slaves tend not to last long once these types of Master's get a hold of them.
Also, slaves who have been on the drug treatments for years develop cognitive deficiencies over time. Since part of the drug's effects interfere with critical thinking. Women can have a Master's in college degree before they are enslaved and are lucky if they can even read after 10 to 15 years of daily treatments. Their mental decline only accelerates from there; a few years later, they lose the ability even to speak or understand language. At that point, it is usually to the dungeon they go. Since they can't pass a discontent check without verbal speech, they are automatically categorized as a security threat.
The resort takes security threats to the status quo very seriously. In the past, Masters have been known to have lapses in judgment in their responsibility as slave owners. They either neglect to medicate their slaves on a regular basis or fail to notice one of them developing a resistance to the medication. Which often results in one of the slaves regaining control of themselves. Usually, what happens is that the woman realizes what has been done to her and complains to the authorities. The Resort has an extensive network of informants both within and outside the government. Once a threat is identified, a cleaner detail is activated and dispatched. They eliminate anyone with knowledge of the incident. Obviously, the woman who filed the complaint is eliminated. But they do not stop there, the Master, any other of his slaves, the police officer who took the report, and so on. Where possible, they make everything look like accidental deaths but have been known to wipe out entire small-town police departments to contain the situation. The original complaint gets deleted for all databases if it never happened.
This rarely happens anymore. Now the sluts have to return to the resort every year for two weeks not only to give other Masters the benefit of using them but to ensure they are not developing a resistance to the treatments. It's almost impossible for a slut to build resistance to the treatments within a year that would not be detected well before they become a threat.
This particular facility can process about 4,000 sluts every two weeks, given there are 26 two-week periods in a year, which gives the capacity of just over 100,000 sluts a year to both enslave and verify sluts remain enslaved. There are other facilities all over the world, some bigger, some smaller, but the organization that runs them all has grown massive and very powerful. The resorts often do not appear on any map, tax map, or even satellite photos; they are non-descript buildings and look more like big warehouses from the outside than resorts. Other times they are hidden in plain sight, another big warehouse in a vast industrial park. Other tenants of the industrial park have no idea that a factory that turns women into slaves is a few hundred yards away from where they work.
Overhead is low as well; the resort is run by women slaves; Master Jerry can count on one hand the number of men that are employees of the resort. From the front desk, cleaning crews, spas, restaurants, maintenance, and security, all obedient slaves. Men are only used to critical positions where actual decisions have to be made.
The Masters who greatly benefit from this arrangement pay a hefty fee each year for membership and the perks that come along with it. Some Wealthy Masters pay for membership out of their own pockets. Others whore out their slaves as prostitutes to generate enough income to pay for membership, usually broken out into monthly payments. They are affordable enough that a Master whoring out his slaves on the side can still make a hefty profit for themselves and still pay for membership. Most Masters only have two slaves, as the fees increase for having more than two become less affordable. This, of course, isn't an issue for the more wealthy Masters. Master Jerry knows of several Arab Princes who have dozens of slaves in their harems.
Master Jerry, being an employee, gets two slaves for free as an employee benefit; he could get another at a discount, but it's still costly. He's content with just enslaving his Wife and 2nd Daughter. Besides gets enough pussy at work any time he wants it. The only downside is that he can't torture the slaves of other Masters; he has to be content with only torturing his own slaves. His Wife was once a dominating woman who routinely belittled him; when his friend Bill told him about a job he thought would be ideal for him, he jumped at the chance. He wasted no time in enslaving his Wife and later his Daughter. He was a little too abusive with his real daughter and ended up killing her accidentally, but the resort was able to provide a replacement. Every year, the resort is allocated a batch of replacement staff for running the resort. There is no retirement plan for Staff slaves; when they get too old, they are eliminated and replaced with younger slaves. Some are kidnapped women, and others are the Daughters of slaves from other Masters. He took extra steps in the treatment process to make his new slave believe she was his real daughter. He had his 2nd Daughter for a number of years now and was satisfied with her performance.
