Slave are creatures common like any other person but their needs are met differently. They are treated in a condescending mannerism, they aren't superior beings and they serve a selected owner to work for to earn what they want but not in paper green but food, clothing or a pretty little collar to eventually escalate towards being treated like a high class slaves.
There are all kinds of slaves. Any kind you choose will be your own, please separate them in a category.
Own a collection of slaves you'd like for sell or to be owned? Great place to choose where to advertise your pretty little caged victims.
