Concubinage : Concubine 

In the Western world, this term has become antiquated and has been replaced the term "living together" if both members of the couple are otherwise unattached, and mistress for a woman who has an ongoing sexual relationship with a married man. The term concubine is generally used to signify an outdated relationship model where the male is the dominant partner, socially and economically. In this model the male may also have one or more wives in addition to the concubine.

Another definition is a woman who is attached to a man solely for reproduction, and caring for the resulting children without any romantic relationship. The father in this case may have a legal wife or other lovers.

Concubinage was frequently voluntary as it provided a measure of economic security for the woman involved in the relationship. When involuntary, "servile concubinage" involves the chattel slavery of one member of the relationship, most typically the woman.
