How to get a slave

You can start with the BDSM personals: The Slave Register, Collarme.com
and other similar sites for consensual slavery. The latter site (collarme) is very BDSM based and that is not what modern slavery is about. A very submissive woman might want her submission deepened through physical pain, but that is not necessary to be a slave. The Gor model is closer to what I am discussing here - see http://www.goreanliving.com/slavery.php

Grow your own

Based on the principles here Wikipedia fifth temperament you would have to assume 1/5 of the population are supine, perhaps 1/10 are submissive - which is many millions of people male and female. Yet only a few thousand are registered on these sites. The rest do not know what they are and go through life without being fulfilled. The same applies to men who would be Masters (and women who would be Mistress).
So one solution is to avoid those sites and instead join "vanilla" dating sites. Once there stress the fact that you are old fashioned and demand obedience and see what comes up. In your exchanges with the girl gradually reveal the extent of the obedience you demand - your right to choose clothes, that you have strict rules, that she must kneel before you, that she be naked for your pleasure as well as doing the housework etc. If the girl fits into the supine category she will be interested. Next test your ability to control and hers to be controlled. Set some task, like to wear a white shirt and take a photo, etc. Do not go for stripping on webcam - that is just sex and slavery is more than that.

When you have your first meeting tell the girl to stand in front of you and turn slowly round so you can "see what you are getting". Why? because through actions like this you are starting to assert your dominance and take control. If she responds to this by giving you control bit by bit then the end result is inevitable and she will be yours. But don't rush it.
From Tanos: Mate as Master
The Enslavement Hypothesis is that there are submissives who have an overwhelming need to be possessed by a dominant. Given the right environment, the submissive can be coaxed out from behind the protective walls she has built during her life and made to expose all of her Self to her master. Among other things this requires that he creates an environment which is emotionally safe and in which her underlying character will be accepted, probably for the first time in her life. During this process, the bond between the submissive and her master becomes sufficiently strong that she can no longer break it herself, and she has then been enslaved.

At a subsequent meeting be sure to ask about STD, has she been checked. Ask about her sexual experiences and find out more about her submissiveness.
Finally when she arrives at your house command her to strip for inspection. Again tell her to stand and turn slowly. Her submissive feelings will be running strongly at this point but do not use her sexually. In any case you need STD tests and arrange contraception before any of that. Focus on taking control. Inspect her teeth, her ears, her breasts. Tell her to lie on the floor and spread her legs then inspect her vagina. If you get this far she is yours.

The next step is to offer her a contract like the example at the foot of this page. One of the contracts specifically does not use the word slave because it can cause alarm. Nevertheless a woman who is totally owned, utterly obedient, punished if she errs, is a slave.

There is one more thing that needs to be done: some permanent reminder for her that she is owned property. My girls wear a Gorean collar, a steel collar that fits round her neck and is locked in place by an Allen screw (see picture). Another option is to get her tattooed with your ownership mark, perhaps a stylized version of your initials. This should be tattooed somewhere most people don't see, like her thigh.




Finally this must be said: ownership of a human being is a huge responsibility, far exceeding that of owning a horse or dog etc. The slave will be relying on you for two important things: security and safety. If you do anything to shake that you could lose the control and lose the slave. Remember her slavery is voluntary. For this reason you must adhere to a policy of utmost honesty. You can do what you like with her - that's your prerogative as her owner - but do it openly. Don't pussy-foot around her sensitivities trying not to upset her - she is yours and you can do what you like. You can fuck her on a whim, make her run naked in the forest, whatever turns you on, make her work her guts out for you earning money. That's slavery. But don't hide things from her, don't do things behind her back or anything that makes her feel unsafe. Be decisive and firm on all issues. Never show weakness.

Contract of consensual slavery (cut and paste into word processor)

I, _____ _____ being of sound mind voluntarily offer myself to you, _____ _____ as your owned property.. This means that I will be your slave just as in traditional slavery where the slave is taken by force except that I give myself to you voluntarily.

I refer to the attached document that I have written which is a table of all the sacrifices I will make and the fears that I have along with my assessment of how I will benefit from this life. I confirm that considering all the items on this list I have decided to give myself to you in trust for better or for worse as chance may be. I understand that if you accept me I will no longer have any choices in my life and that all choices and decisions will be yours to make not mine.

I understand that you will train me to be more obedient, and to focus on your needs and pleasures above all else. I sincerely ask that over time you remove my remaining desires to be independent and help me become a better slave. I beg you to help this to become second nature to me. I understand that this process may involve physical punishment and discipline and I assert that I will be happier as your slave if you do this over-riding any objections I may have.

I wish to become your owned property and like any high value animal I expect to be put to work. Any and all earnings will be yours to dispose of as you wish without question. Money will no longer be my concern. I also understand that like any owned animal you will see to it that all my medical and other needs are met. However those needs will be determined by you not by me.

I promise to live in harmony with your existing slaves present or future as my slave sisters and to respect their strengths and weaknesses just as you wish them to respect mine.

I hereby offer myself to you to do with as you wish. You are my Lord and Master, Lord of my mind and body. If you accept me I beg that should I try to escape or demand my release that you use any force or restraint necessary to keep me under your control and ownership.
