Pirates of Venus by Edgar Rice Burroughs — Read

For some time I had been aware that I was in the house of Mintep, the king, and that the country was called Vepaja. Jong, which I had originally thought to be his name, was his title; it is Amtorian for king. I learned that Duran was of the house of Zar and that Olthar and Kamlot were his sons; Zuro, one of the women I had met there, was attached to Duran; the other, Alzo, was attached to Olthar; Kamlot had no woman. I use the word attached partially because it is a reasonably close translation of the Amtorian word for the connection and partially because no other word seems exactly to explain the relationship between these men and women.

They were not married, because the institution of marriage is unknown here. One could not say that they belonged to the men, because they were in no sense slaves or servants, nor had they been acquired by purchase or feat of arms. They had come willingly, following a courtship, and they were free to depart whenever they chose, just as the men were free to depart and seek other connections; but, as I was to learn later, these connections are seldom broken, while infidelity is as rare here as it is prevalent on earth.
