The Keintapans have a system of slavery, although it isn't fully fleshed yet. The Keintapans were meant to be a conglomeration of stereotypical commies, nazis, and a feminist's worst nightmare.
In Keintapan society, from an outsider's point of view, there are four classes of slaves: "free" women, men, women, and eduated. "Free" women are simply normal women. They are bound to their closest male relative, whether it's their father, brother, husband, son, and so forth. Unlike in other traditional societies where women are bound to males, the woman, in this case, is legally bound and her "master" can transfer her to another male in the family legally and even sell her to be a normal slave if he so wants. Depending on the region, "free" women might be treated just like normal slaves.
Male slaves are male slaves.
Women slaves are women slaves. They also tend to be sex slaves, although this is really up to the master. The Keintapans use the analogy of a dog - you can play games with a dog, but not everyone wants to; similarly, you can bone your female slave, but not everyone might want to. However, Keintapans also consider it good etiquette to share a female sex slave - especially an attractive one - with your friends and other family members. Refusing to do so makes you look, in their eyes, as selfish and inconsiderate (sort of like sharing your toys, or sharing your food, or sharing your car, etc.). This practice started to slowly die away once Keintapa began to get some influence from the significantly more liberal Aidisese Empire. Anyhow, however, Keintapans consider pedophilia undesirable, so boning a 10 year old girl is not considered good. This is not necessarily because of some kind of higher moral standard, but rather because Keintapans consider children to not have sufficient "adult energy" (or something like that), and boning one would drain your energy as it takes away your "adult energy".
Educated slaves, the rarest type, are like the educated slaves in Rome and Greece who would tutor children. For instance, they might serve as secretaries to their masters, or even the equivalent of business partners in all but name. In a sense, these men (and very, very rarely, women) are really slaves in all but name - legally they are owned by their master, but due to how their help, they often are very independent.
Slaves can also be owned by corporations, businesses, and other non-person entities. Male slaves are most often used for labor and female slaves most often used for prostitution, for instance. Sometimes, businesses such as inns and restaurants might provide a female slave as a kind of business appreciation for customers. Anyhow, educated slaves also work for the government, and many are in-fact standard bureaucrats who report to their masters who happen to be supervisors and so forth.
Again, the entire system is not fully fleshed, since Keintapa isn't really my focus conculture, and it's sort of meant to be slightly over the top in a way.
