I've got some more info for you, Deborah.
Talked to my Professor again and he said that there was no specific name for when the master had sex with the slaves. However, he did say that the women (slave) were referred to as slave mistresses. In Louisiana, South Carolina and Georgia, they were sometimes called a concubine or a plaçage due to the French influence in those areas. He said that these women were normally in the house and had to have sex with the master whenever he wanted. He said this was also related to the quadroon ball. A quadroon is someone that is 3/4 white and 1/4 black. In this event, the parents, particularly the mothers would dress up the daughters, especially if they were quadroons since they had the most exotic looks, and basically auction them off to a rich person. He basically said this was like a whore house without the sex. The sex came after they bought the girl. That's all I can remember for now.
